Description

Die Erfindung betrifft eine transportable Reinigungsvorrichtung für Wärmetauscher, insbesondere Luftkondensationsanlagen.The invention relates to a portable cleaning device for heat exchangers, in particular air condensation plants.

Luftkondensationsanlagen (Lukos) werden als ein geschlossenes System zur Kondensierung des Abdampfes bzw. des Überschußdampfes von Turbinenanlagen verwendet. Die Gesamtkühlfläche ist für die produzierte Dampfmenge ausgelegt. Dabei wird von einem bestimmten Wärmeübergang von der Kühlfläche in die Umgebungsluft ausgegangen. Der Wärmeübergang bleibt jedoch nicht konstant. An den Kühlflächen kommt es außen zur Verschmutzung. Die Verschmutzung wird unter anderem durch Blütenpollen, Laub, Industrieabgase, Flugstäube verursacht und führt zu Belägen an den Kühlflächen. Dadurch verschlechtert sich der Wärmeübergang.Air condensation plants (Lukos) are used as a closed system for condensing the exhaust steam or the excess steam of turbine plants. The total cooling surface is designed for the amount of steam produced. It is assumed that a certain heat transfer from the cooling surface into the ambient air. The heat transfer, however, does not remain constant. On the cooling surfaces it comes to the outside for pollution. Pollution is caused, inter alia, by pollen, leaves, industrial emissions, flue dust and leads to deposits on the cooling surfaces. As a result, the heat transfer deteriorates.

Anfänglich auftretende Verunreinigungen können durch evtl. vorhandene Drehzahlreserven der Lüfter ausgeglichen werden. Das hat bereits den Nachteil höheren Energieaufwandes zum Betrieb der Anlage.
Eine weitere Verschmutzung kann nicht mehr kompensiert werden. Sie führt zu einer Reduzierung des Wärmeüberganges und somit zu einer verminderten Kühlleistung für die Dampfkonsation.Initially occurring impurities can be compensated by possibly existing speed reserves of the fans. This already has the disadvantage of higher energy consumption for operating the system.
Further pollution can not be compensated. It leads to a reduction of the heat transfer and thus to a reduced cooling capacity for the steam consumption.

Infolge der nachlassenden Kühlwirkung steigt der Dampfdruck in der Abdampfleitung. Die Turbine verliert an Leistung. Die Energieerzeugung des Generators verringert sich. Üblicherweise reagieren die Anlagen darauf. Sind z.B. Turbinen für einen Abdampfdruck von 0,2bar absolut ausgelegt, werden sie bei einem Anstieg des Dampfdruckes auf 0,8 bar durch Überwachungseinrichtungen abgeschaltet.As a result of the decreasing cooling effect, the vapor pressure in the exhaust steam line increases. The turbine loses power. The power generation of the generator is reduced. Usually, the systems react to this. Are e.g. Turbines are designed for an Abdampfdruck of 0.2 bar absolute, they are switched off with a rise in the vapor pressure to 0.8 bar by monitoring devices.

Bei Wasserkühlern und Produktkühlem, wie sie vorzugsweise in der chemischen Industrie vorkommen, finden sich die gleichen Probleme. Auch hier kann ein Nachlassen des Wärmeüberganges anfänglich durch vorhandene Luftmengenreserven ausgegleichen werden.With water coolers and product coolers, as they are preferably in the chemical industry, find the same problems. Again, a decrease in heat transfer initially be compensated by existing reserves of air reserves.

Danach kommt es jedoch zu einem stetigen Temperaturanstieg im Wasserkreislauf oder Produktstrom. Das führt in absehbarer Zeit zu einer Betriebsstörung.Thereafter, however, there is a steady increase in temperature in the water cycle or product flow. This will lead to a malfunction in the foreseeable future.

Obige Zusammenhänge sind den Betriebsleuten hinlänglich bekannt.
Es liegt auf der Hand, daß der Verschmutzung der Kühlflächen durch Reinigung entgegengewirkt wird.The above relationships are well known to the operators.
It is obvious that the contamination of the cooling surfaces is counteracted by cleaning.

Vorzugsweise wird die Reinigung manuell ausgeführt. Die Reinigungsarbeiten werden zumeist den Reinigungskolonnen übertragen, denen auch sonstige Reinigungsarbeiten unterliegen. Es besteht die Neigung, diese Arbeiten als Gesamtpaket zu vergeben. Bei allen Reinigungsunternehmen stehen jedoch nur Hand-Dampfstrahlgeräte bzw. Hochdruckwasserstrahlgeräte zur Verfügung. Der Erfolg der Arbeiten mit einem Handgerät ist gering. Es wird nur der lose sitzende Schmutz abgespült. Hinzu kommt, daß die Kühlflächen mehrlagig angeordnet sind bzw. aus Rippenkühlern mit sehr hohen Rippen bestehen. Bei mehrlagigen Kühlrohren verursacht eine unsachgemäße Vorgehensweise bzw. der Einsatz von ungeeignetem Gerät nur ein Lösen von Schmutz an der oberen Lage und ein Anlagern an unteren Reihen/Lagen. Bei Kühlflächen mit hohen Rippen besteht die gleiche Gefahr. Auf dem Wege kann der Kühlluft sogar der Durchtritt durch den Kühler versperrt werden.Preferably, the cleaning is carried out manually. The cleaning work is usually transferred to the cleaning crews, which are also subject to other cleaning work. There is a tendency to award this work as a complete package. For all cleaning companies, however, only manual steam jet equipment or high pressure water jet equipment are available. The success of working with a handheld device is low. It is rinsed off only the loose-fitting dirt. In addition, the cooling surfaces are arranged in multiple layers or consist of fin coolers with very high ribs. In the case of multi-layer cooling tubes, an improper procedure or the use of unsuitable equipment only causes a loosening of dirt on the upper layer and an attachment to lower rows / layers. Cooling surfaces with high ribs are at the same risk. On the way, the cooling air can even be blocked from passing through the radiator.

Außerdem hat sich an Kühlem mit Aluminiumkühlrippen gezeigt, daß mit den Hochdruckgeräten ganz leicht eine Beschädigung an den Rippen verursacht werden kann. Der übermäßige Druck verbiegt die Rippen bei unsachgemäßer Beaufschlagung. Den Betriebsleuten wird das nicht sofort deutlich, weil die Kühlflächen üblicherweise nicht regelmäßig befahren, d.h. beobachtet werden. So ist nicht zu kontrollieren, wann und wer welchen Schaden angerichtet hat und haben sich Situationen ergeben, in denen die Kühler durch Reinigung unbrauchbar wurden.In addition, it has been shown on Kühl with aluminum cooling fins that with the high pressure equipment easily damage to the ribs can be caused. Excessive pressure will bend the ribs if handled improperly. This is not immediately obvious to the operators, because the cooling surfaces are usually not regularly driven, i. to be watched. Thus, it is not possible to control when and who caused what damage and have encountered situations in which the radiator were unusable by cleaning.

Ein älterer Vorschlag sieht stationäre Reinigungseinrichtungen vor, mit denen eine zuverlässige Reinigung der Kühlflächen erreicht wird. Bei derartigen Reinigungsvorrichtungen können die Reinigungsdüsen, ihre Stellung und der Reinigungsdruck den Kühlflächen angepaßt werden. Dadurch wird eine tatsächliche Reinigung ohne die Gefahr einer Beschädigung möglich.An older proposal provides stationary cleaning facilities, with which a reliable cleaning of the cooling surfaces is achieved. In such cleaning devices, the cleaning nozzles, their position and the cleaning pressure can be adapted to the cooling surfaces. This will allow actual cleaning without the risk of damage.

Ein anderer älterer Vorschlag sieht vor, daß eine Reinigungsvorrichtung für mehrere Kühlflächen (Kühlregister) einer Anlage verwendet wird. Das wird mit Hilfe einer Fahranlage erreicht. Die Fahranlage ähnelt einer Kranbahn, mit der die Vorrichtung von einer Kühlfläche zur anderen umgesetzt wird.
Die stationären Reinigungsvorrichtungen und auch die umsetzbare Reinigungsvorrichtung haben allerdings gemeinsam, daß zunächst ein erheblicher Investitionsaufwand getätigt werden muß. Das steht naturgemäß dem Einsatz solcher Geräte entgegen.Another prior proposal provides that a cleaning device for multiple cooling surfaces (cooling registers) of a system is used. This is achieved by means of a driving system. The driving system resembles a crane track, with which the device is converted from one cooling surface to the other.
However, the stationary cleaning devices and the implementable cleaning device have in common that initially a considerable investment must be made. This naturally precludes the use of such devices.

Nach einem anderen älteren Vorschlag der DE 19800018 A wird obigen Problemen dadurch begegnet, daß

  • a) eine tragbare Reinigungsvorrichtung mit einem sich vertikal über die Höhe des Kühlregisters erstreckenden Fahrwagen geschaffen wird, der horizontal verfahrbar ist und eine darauf vertikal verfahrbaren Düsenstock trägt.
  • b) der mehrere Kühlrohre oder auch mehrere Kühlregister übergreift und
  • c) die Reinigungsvorrichtung eine Tragkonstruktion mit einem in Fahrrichtung des Fahrwagens verlaufenden Kantprofil besitzt und der Fahrwagen auf dem Kantprofil verfahrbar angeordnet ist und/oder die Tragkonstruktion durch Steckverbindungen längenänderbar ist
According to another older proposal of DE 19800018 A, the above problems are met by the fact that
  • a) a portable cleaning device with a vertically over the height of the cooling register extending carriage is provided which is horizontally movable and carries a vertically movable thereon nozzle.
  • b) the plurality of cooling tubes or more cooling register overlaps and
  • c) the cleaning device has a support structure with a running in the direction of travel of the trolley edge profile and the carriage is arranged movably on the edge profile and / or the support structure is length-adjustable by connectors

Dabei können auch zwei oder mehr Kantprofile nebeneinander angeordnet sein. Die Verwendung eines einzigen Kantprofiles beinhaltet jedoch einen besonderen Schritt zu einer optimal leichten und zugleich funktionssicheren Vorrichtung. Der Gewichtsvorteil eines einzigen Kantprofiles ist nicht ohne weiteres erkennbar, weil mehrere nebeneinander angeordnete Kantprofile bei gleichem Materialaufwand rechnerisch einen größeren Biegewiderstand als ein einziges Kantprofil besitzen. Gleichwohl kommt es nicht allein auf das größere Widerstandsmoment an. Es kommt auch darauf an, daß die Führungsrollen keine Deformierung der Rollflächen verursachen. Das führt zu einer Mindestdicke der Rollflächen und Kantprofile. Zwei mindestdicke Kantprofile können einen größeren Materialaufwand als ein einziges tragfähiges Kantprofil zur Folge haben.In this case, two or more edge profiles can be arranged side by side. However, the use of a single Kantprofile includes a special step to an optimally lightweight and at the same time functionally reliable device. The weight advantage of a single Kantprofiles is not readily apparent, because a plurality of juxtaposed Kant profiles with the same cost of material computationally have a greater bending resistance than a single edge profile. Nevertheless, it is not just about the larger moment of resistance. It is also important that the guide rollers do not cause deformation of the rolling surfaces. This leads to a minimum thickness of the rolling surfaces and edge profiles. Two minimum-thickness edge profiles can result in a greater cost of materials than a single, stable edge profile.

Vorzugsweise ist das Kantprofil als Hohlprofil ausgebildet und durch Steckverbindungen längenänderbar. Die Längenänderbarkeit erleichtert die Arbeit mit einer einzigen Vorrichtung an verschiedenen Lukos oder dergleichen. Unabhängig vom Kantprofil kommen der Längenänderbarkeit und der Steckverbindung deshalb auch eine besondere Bedeutung zu.
Das Kantprofil und die Steckverbindung sind für eine Längenänderung günstig. Nach dem älteren Vorschlag kann das Kantprofil aus mehreren Teilen zusammengesetzt werden. Die Vorrichtung kann aber auch einen Kopf und einen Fuß und zwischen Kopf und Fuß ein zur Längenänderung auswechselbares Kantprofil besitzen.Preferably, the edge profile is formed as a hollow profile and length-adjustable by connectors. The extensibility facilitates work with a single device at different Lukos or the like. Regardless of the edge profile of the extensibility and the connector are therefore also of particular importance.
The edge profile and the plug connection are favorable for a change in length. After the older proposal, the edge profile can be composed of several parts. However, the device may also have a head and a foot and between the head and foot a changeable for length change edge profile.

Die Steckverbindung wird mit Hilfe von separaten Dornen/Zapfen herbeigeführt, die in zwei miteinander zu verbindende Rohrenden greifen. Es können aber auch Dorne/Zapfen an den Rohrenden angebracht werden, so daß das eine Rohr mit einem Dorn/Zapfen in das andere Rohr greift.
Zur weiteren Gewichtsersparnis können die Dorne/Zapfen hohl bzw. ihrerseits als Rohre ausgeführt sein.
Die Steckverbindung kann selbstklemmend ausgelegt sein und/oder eine mechanische Sicherung ausgelegt sein.
Wahlweise befinden sich nach dem älteren Vorschlag an Kopf und Fuß der Vorrichtung Arme für unterschiedliche Zwecke, z.B. zur Abstützung und/oder Führung und/oder Halterung der Vorrichtung und/oder zur Halterung von Führungsrollen/Rädern/Scheiben und/oder zur Halterung von Antrieben und/oder Pumpen vorgesehen sein.
Die Halterungen für Rollen/Räder/Scheiben können verstellbar oder fest angeordnet werden.The plug-in connection is brought about by means of separate spikes / pins, which engage in two pipe ends to be connected to each other. But it can also spikes / pins are attached to the pipe ends, so that engages a pipe with a mandrel / pin in the other tube.
To further weight savings, the mandrels / pins hollow or in turn be designed as tubes.
The connector may be designed self-clamping and / or designed a mechanical fuse.
Optionally, according to the older proposal at the head and foot of the device arms for different purposes, eg for supporting and / or guiding and / or holding the device and / or for holding guide rollers / wheels / discs and / or for holding drives and Be provided / or pumps.
The holders for wheels / wheels / discs can be arranged adjustable or fixed.

Wahlweise können die Arme und/oder Kopf und/oder Fuß aus Teilen lösbar zusammengesetzt sein, so daß ein Auswechseln in Anpassung an bestimmte Bedürfnisse möglich ist. Günstig kann dabei eine Steckverbindung wie bei dem Kantprofil sein. Dem ist förderlich, wenn sich Arme, Kopf und Fuß aus gleichen Profilen zusammensetzen.Optionally, the arms and / or head and / or foot may be releasably assembled from parts so that replacement in adaptation to particular needs is possible. Conveniently can be a plug connection as in the edge profile. This is beneficial if the arms, head and foot are made up of the same profiles.

Vorzugsweise gehören zu dem Antrieb ein Kraftübertragungsmittel wie Band, Kette, Seil oder Riemen, insbesondere ein Zahnriemen, und ein Getriebemotor mit einem Antriebsritzel. Mit den Rollen/Rädern/Scheiben wird das Kraftübertragungsmittel vorzugsweise über Kopf und Fuß hinweg geführt und die notwendige Spannung erzeugt. Zur Spannungserzeugung ist die zugehörige Rolle/Rad/Scheibe quer zur Längsrichtung des Kraftübertragungsmittels verstellbar.Preferably, the drive includes a power transmission means such as a belt, chain, rope or belt, in particular a toothed belt, and a geared motor with a drive pinion. With the rollers / wheels / discs, the power transmission means is preferably passed over the head and foot and generates the necessary tension. To generate voltage, the associated roller / wheel / disc is adjustable transversely to the longitudinal direction of the power transmission means.

Das Kraftübertragungsmittel greift an den Fahrwagen und wird mittels des Getriebemotors bewegt. Dabei kann das Kraftübertragungsmittel um das Antriebsritzel herumgeführt oder mittels einer weiteren Rolle/Rades/Scheibe gegen das Antriebsritzel gedrückt werden.The power transmission means engages the carriage and is moved by means of the geared motor. In this case, the power transmission means can be guided around the drive pinion or pressed by means of another roller / wheel / disc against the drive pinion.

Zur Gewichtsreduzierung tragen die Verwendung von Aluminium für die Profile und eine beschränkte Breite der Düsen bzw. des Düsenstockes im Fahrwagen bei. Die Beschränkung wird mit der Anzahl der an einem Rohr im Düsenstock angeordneten Düsen gegeben.To reduce weight, the use of aluminum for the profiles and a limited width of the nozzles or the nozzle assembly in the carriage contribute. The restriction is given with the number of nozzles arranged on a pipe in the nozzle.

Die Düsen bzw. der Düsenstock kann trotz beschränkter Breite durch Verfahren auf der gesamten Breite/Länge des Fahrwagens alle darunter liegenden Kühlrohre reinigen. Die starke Gewichtsreduzierung schont auch die Kühlregister. Das ist vor allem für Kühlregister mit empfindlichen Kühlrippen wichtig. Zu den empfindlichen Kühlrohren/Rippen gehören z.B. diejenigen mit rechteckigem Querschnitt, zwischen denen die Kühlrippen als meanderndes Metallband hin- und hergeführt sind.Despite limited width, the nozzles or the nozzle block can clean all the cooling tubes below by processes along the entire width / length of the trolley. The heavy weight reduction also protects the cooling coils. This is especially important for cooling coils with sensitive cooling fins. The sensitive cooling tubes / ribs include e.g. those with rectangular cross-section, between which the cooling fins are guided back and forth as a meandering metal band.

Hinzu kommt, daß das geringe Gewicht keine Gefahr einer übermäßigen Belastung der Kühlregister mit sich bringt.In addition, the low weight brings no risk of excessive load on the cooling coil with it.

Durch Übergreifen mehrerer Kühlregister und Verfahren der Reinigungsdüsen in dem Fahrwagen von einem Kühlregister zum anderen wird eine optimale Arbeitsgestaltung und Arbeits- und Betriebszeitnutzung erreicht.By overlapping several cooling registers and moving the cleaning nozzles in the trolley from one cooling register to the other, an optimal work design and working and operating time utilization is achieved.

Die Wasserversorgung der Reinigungsvorrichtung kann über eine mitgeführte Schlauchleitung erfolgen. Wahlweise wird das Wasser über eine zwischengeschaltete Pumpe auf den gewünschten Druck gebracht. Die Pumpe kann an der Vorrichtung befestigt oder separat vor der Vorrichtung aufgestellt werden.The water supply to the cleaning device can take place via a hose line entrained. Optionally, the water is brought to the desired pressure via an intermediate pump. The pump can be attached to the device or placed separately in front of the device.

Bei besonders breiten Kühlanlagen mit einer Vielzahl von nebeneinander angeordneten Registern ist es von Vorteil, im oberen Bereich der Kühlregister und/oder an deren Halterung und/oder an dem Gebäude Laufschienen anzubringen, in bzw. auf denen die Vorrichtung verfahrbar ist, so daß die Reinigungsvorrichtung zum Umsetzen auf ein benachbartes Kühlregister nicht mehr gelöst werden muß, sondern verfahren werden kann.In particularly wide cooling systems with a plurality of juxtaposed registers, it is advantageous to provide in the upper region of the cooling coil and / or on the support and / or on the building rails in or on which the device is movable, so that the cleaning device to implement on an adjacent cooling coil no longer needs to be solved, but can be moved.

Der Erfindung liegt die Aufgabe zugrunde, die vorstehend beschriebene tragbare Reinigungsvorrichtung noch zu verbessern. Das wird mit den Merkmalen der geltenden Ansprüche erreicht.The invention has for its object to improve the portable cleaning device described above yet. This is achieved with the features of the current claims.

Ein wesentliches Merkmal der Erfindung bilden portalförmige Bügel, unter denen der Düsenstockwagen verfahrbar ist.
In bevorzugter Ausführung ist an den Bügeln der Reinigungsvorrichtung eine Leiter befestigt. Dies kann dadurch dargestellt werden, daß die Bügel zumindest teilweise aus einem Leiterprofil bestehen.
Wahlweise ist auch eine Höhenverstellung an der Leiter vorgesehen.
Günstig ist, wenn die Leiter klappbare Stufen bzw. Sprossen und/oder ein klappbares Geländer besitzt.An essential feature of the invention form portal-shaped bracket, under which the nozzle floor carriage is movable.
In a preferred embodiment, a conductor is attached to the temples of the cleaning device. This can be represented by the fact that the stirrups consist at least partially of a conductor profile.
Optionally, a height adjustment is provided on the ladder.
It is favorable if the ladder has foldable steps or rungs and / or a foldable railing.

In der Zeichnung ist zunächst der ältere Vorschlag dargestellt.

To the cleaning device includes a linkage with a replaceable square tube 2. The tube 2 has an edge length of 50 mm with 2.5mm wall thickness. At the left end in the drawing, the tube 2 is connected to a foot 5 and at the right end in the drawing with a head 6. The head 6 and the foot 5 form extensions 3 and 4 of the tube 2 and have arms 10 and 11 and 7 and 8. With the arms 7 and 1 O takes place a support. Accordingly, a support roller 12 is provided on the arm 1 O of the foot 3, while on the arm 7, a bracket 13 is guided with a roller in a profile tube 14 and in addition to acting perpendicular to the longitudinal axis of the tube 2 supporting forces and the vertical force absorbs. The profile tube 14 is held with brackets 15 on the radiator.

An dem Arm 8 befindet sich eine verstellbar angeordnete Führungsrolle 9. Die Verstelleinrichtung wird durch eine rohrförmige Hülse mit einer Stellschraube 18 gebildet.
An dem Arm 11 ist ein Getriebemotor 17 mit einem Zahnriemenantrieb bzw. Ritzel 24 verstellbar gehalten. Die Verstellung wird in gleicher Weise wie für die Rolle 9 bewirkt. Die zugehörige Hülse ist mit 16 bezeichnet.On the arm 8 is an adjustably arranged guide roller 9. The adjusting device is formed by a tubular sleeve with a set screw 18.
On the arm 11, a geared motor 17 is held with a toothed belt drive or pinion 24 adjustable. The adjustment is effected in the same way as for the roller 9. The associated sleeve is designated 16.

Ferner trägt der Fuß 5 am Ende der Rohrverlängerung 3 eine Halterung für zwei Rollen 22 und 23. Desgleichen finden sich an der Rohrverlängerung 4 des Kopfes 6 eine Halterung und zwei Rollen 19 und 20.Furthermore, the foot 5 carries at the end of the pipe extension 3, a holder for two rollers 22 and 23. Likewise found on the pipe extension 4 of the head 6, a holder and two rollers 19 and 20th

Die Rollen 9,19,20,22 und 23 dienen der Führung für einen Antriebsriemen 21. Der Riemen 21 ist als Zahnriemen ausgebildet und an einem Fahrwagen 25 befestigt, der mit Rollen 26 auf dem Rohr 2 verfahrbar angeordnet ist. Die Rollen 26 laufen auf den ebenen Flächen des Vierkantrohres. Dadurch, daß auf allen Flächen Rollen 26 laufen, ist der Fahrwagen auf dem Rohr 2 gesichert.
Der Fahrwagen 25 trägt einen Düsenstock mit zwei quer zur Längsrichtung der Kühlrohre angeordneten Wasserzuführungsrohren 27 und 28, die durch eine weiteres Rohr 29 miteinander verbunden sind. An den Wasserzuführungsrohren 27 und 28 sind Düsen 30 angeordnet, aus den die Kühlrohre mit Wasser beaufschlagt werden.The rollers 9,19,20,22 and 23 serve to guide a drive belt 21. The belt 21 is formed as a toothed belt and attached to a trolley 25 which is arranged with rollers 26 on the tube 2 movable. The rollers 26 run on the flat surfaces of the square tube. Characterized in that run on all surfaces rollers 26, the carriage is secured to the tube 2.
The carriage 25 carries a nozzle with two transversely to the longitudinal direction of the cooling tubes arranged water supply pipes 27 and 28, which are interconnected by a further pipe 29. At the water supply pipes 27 and 28 nozzles 30 are arranged, from which the cooling tubes are supplied with water.

Die Wasserzuführung erfolgt über eine nicht dargestellte, mitgeführte Schlauchleitung und eine zwischengeschaltete und separat aufgestellte Pumpe.The water supply via a not shown, entrained hose and an intermediate and separately installed pump.

Die Vorrichtung nach Fig.2 dient gleichfalls der Reinigung geneigter Kühlflächen und unterscheidet sich von der nach Fig. 1 durch ein an dem Kühler angebrachtes Doppel-T-Profil 35, auf dem der Kopf mit Rollen 36 läuft. Die Rollen 36 sind am Arm 7 gehalten. Diese Konstruktion ist besonders zur Aufnahme hoher Vertikalkräfte geeignet.The apparatus of Figure 2 also serves to clean inclined cooling surfaces and differs from that of FIG. 1 by a mounted on the radiator double T-profile 35 on which the head with rollers 36 runs. The rollers 36 are held on the arm 7. This construction is particularly suitable for receiving high vertical forces.

Die Vorrichtung nach Fig.3 unterscheidet sich von der nach Fig. 1 durch die Anwendung auf Flachkühler. D.h. die Darstellung stimmt hier mit der tatsächlichen Anordnung überein. Nach Fig. 3 besitzt der Arm 7 wie der Arm 10 nach Fig. 1 nur eine einfache Stützrolle 37.The device of Figure 3 differs from that of FIG. 1 by the application to flat cooler. That the representation here agrees with the actual arrangement. According to Fig. 3, the arm 7 as the arm 10 of FIG. 1 has only a simple support roller 37th

In allen Ausführungsformen sind in der Darstellung jeweils zwei Rollen 12 bzw. 36 bzw. 37 senkrecht zur Zeichnungsebene hintereinander angeordnet, um der Vorrichtung die notwendige Stabilität gegen Kippen zu geben.
Ferner ist in allen Vorrichtungen das Rohr 2 zur Anpassung an den jeweiligen Kühler auswechselbar. Dazu sind zwischen dem Rohr 2 und Kopf 6 und Fuß 5 Steckverbindungen vorgesehen. Die Anschlußstellen am Kopf 6 und Fuß 5 werden durch rohrförmige Zapfen gebildet, die in das Rohr 2 greifen. Entsprechend dem Innenmaß des Rohres 2 von 45 mm Kantenlänge wird ein Zapfen mit geringfügig kleinerem Außenmaß verwendet.
Die Rohrverlängerungen 3 und 4 sind in gleicher Weise lösbar mit Kopf 6 und Fuß 5 verbunden wie das Rohr 2.In all embodiments, two rollers 12 and 36 or 37 are arranged perpendicular to the plane of the drawing one behind the other in the illustration in order to give the device the necessary stability against tilting.
Furthermore, the tube 2 is replaceable for adaptation to the respective radiator in all devices. For this purpose 5 connections are provided between the tube 2 and head 6 and foot. The connection points on the head 6 and foot 5 are formed by tubular pins which engage in the tube 2. According to the inner dimension of the pipe 2 of 45 mm edge length, a pin with a slightly smaller external size is used.
The pipe extensions 3 and 4 are releasably connected in the same way with the head 6 and foot 5 as the tube. 2

Durch Längenänderung der Arme 7 und 10 kann der Abstand der Düsen zu dem Kühlregister optimiert werden. Für die Längenänderung sind die Arme 7 und 10 in nicht dargestellter Form teleskopierbar und in der jeweiligen Stellung arretierbar. Die Teleskopierbarkeit wird durch ineinander verschiebbare Rohre bewirkt, die Arretierung durch Stellschrauben.By changing the length of the arms 7 and 10, the distance of the nozzles to the cooling register can be optimized. For the change in length, the arms 7 and 10 in a manner not shown telescopic and can be locked in the respective position. The telescoping is effected by telescoping tubes, the locking by adjusting screws.

Zur Reinigung werden die Düsen mit Wasser beaufschlagt und wird durch Betätigung des Getriebemotors der Fahrwagen über dem Kühlregister hin- und her verfahren, bis der gewünschte Reinigungsgrad erreicht ist. Danach wird die Reinigungsvorrichtung senkrecht zur Bildebene über ein noch verschmutztes Kühlregister verfahren und erneut die Reinigung in Gang gesetzt.For cleaning, the nozzles are charged with water and is moved back and forth by pressing the geared motor of the car over the cooling coil until the desired degree of cleaning is achieved. Thereafter, the cleaning device is moved perpendicular to the image plane over a still dirty cooling register and set the cleaning again in motion.

Die hin- und hergehende Bewegung des Fahrwagens mit den Düsen wird durch Endschalter gesteuert.The reciprocating motion of the truck with the nozzles is controlled by limit switches.

Bei den vorstehend beschriebenen Reinigungsvorrichtungen, können die Düsen bzw. der Düsenstock nicht über den Kopf bzw. Fuß der Reinigungsvorrichtung hinaus bewegt werden. Das ist bei einigen Kühlregistern von Nachteil, weil die Anlage nicht so weit verlängert werden kann, daß das gesamte Kühlregister im Zugriff der Düsen liegt. Die Gründe sind unterschiedlich. Nach der Erfindung wird auch in solchen Fällen eine Reinigung möglich, weil die Düsen über den Kopf der Vorrichtung hinausbewegt werden können. Dazu gehört einerseits eine ausreichende Bewegungsfreiheit für die Düsen bzw. den Düsenstock. Das wird erreicht durch portalförmige Bügel.
Ferner ist der Düsenstock so groß angelegt, daß er in der obersten Stellung in gewünschtem Maß gegenüber dem Kopf der Vorrichtung vorragt.
Die Fig. 4 zeigt eine solche erfindungsgemäße Vorrichtung.
Die Vorrichtung besitzt die gleichen Elemente wie die Vorrichtungen nach den Fig. 1 bis 3. Die Düsen sind zu mehreren in einem Düsenstock 50 angeordnet. Die Düsen sind in unterschiedlichen Reihen angeordnet, wobei die Düsen der einen Reihe eine andere Richtung als die Düsen der anderen Reihe besitzen. Die unterschiedlich gerichteten Düsen sind in Fig. 5 und 6 dargestellt. Ziel der unterschiedlichen Düsenrichtung ist ein unterschiedliches Anspritzen der Kühlrohr 51.
Die Kühlrohre 51 sind zu Registern zusammengefaßt. Die Kühlregister sind zwischen Trägem 52 der Kühlkonstruktion gehalten.
Die Fig. 5 und 6 zeigen einen Querschnitt, die Fig. 4 eine Seitenansicht. In der Seitenansicht ist die Neigung des Kühlregisters dargestellt. Dabei ergeben sich am oberen Ende des Kühlregisters sehr beengte Verhältnisse, im Ausführungsbeispiel wegen einer Windwandabstützung. Infolgedessen kann das Vierkantprofil 2 nicht so weit verlängert werden, daß die Reinigungsvorrichtung mit ihrem Kopf das obere Ende des Kühlregisters erreicht. Nach Fig. 4 kann das dadurch ausgeglichen werden, daß der Düsenstock 50 in der oberen Stellung entsprechend weit über den Kopf der Reinigungsvorrichtung hinausragt.
Das ist im Ausführungsbeispiel aufgrund der portalförmigen Bügel 53 möglich, mit denen die Reinigungsvorrichtung gehalten wird.
Die portalförmigen Bügel 53 bilden zusammen mit dem Kantprofil 2 einen Tragwagen, der seitlich auf den Kühlregistern verfahrbar ist. Der Tragwagen trägt alle zur Reinigungsvorrichtung gehörenden Komponenten, wie sie bereits Gegenstand des älteren Vorschlages sind. Dazu gehören im Ausführungsbespiel ein Zahnriementrieb (statt Riementrieb kann auch Kettenzug oder eine andere Zugeinrichtung mit Band oder Seil vorgesehen sein), der Antrieb und der Düsenstockwagen.
Zum Verfahren sind unten an den Bügel 53 Fahrrollen vorgesehen. Die Fahrrollen besitzen eine Arretierung in Form einer Klemme. Die Einzelheiten sind in Fig. 7 dargestellt.In the cleaning devices described above, the nozzles or the nozzle can not be moved beyond the head or foot of the cleaning device. This is disadvantageous in some cooling registers, because the system is not extended so far can be that the entire cooling coil is in the access of the nozzles. The reasons are different. According to the invention, a cleaning is also possible in such cases, because the nozzles can be moved beyond the head of the device. This includes on the one hand sufficient freedom of movement for the nozzles or the nozzle. This is achieved by portal-shaped bracket.
Furthermore, the nozzle is designed so large that it protrudes in the uppermost position to the desired extent relative to the head of the device.
Fig. 4 shows such a device according to the invention.
The device has the same elements as the devices according to FIGS. 1 to 3. The nozzles are arranged in multiple in a nozzle 50. The nozzles are arranged in different rows, wherein the nozzles of one row have a different direction than the nozzles of the other row. The differently directed nozzles are shown in FIGS. 5 and 6. The aim of the different nozzle direction is a different injection of the cooling tube 51st
The cooling tubes 51 are combined into registers. The cooling registers are held between supports 52 of the cooling structure.
Figs. 5 and 6 show a cross section, Fig. 4 is a side view. In the side view, the inclination of the cooling register is shown. This results in very cramped conditions at the upper end of the cooling register, in the exemplary embodiment because of a wind wall support. As a result, the square profile 2 can not be extended so far that the cleaning device reaches with its head the upper end of the cooling register. According to Fig. 4, this can be compensated by the fact that the nozzle 50 protrudes in the upper position corresponding far beyond the head of the cleaning device.
This is possible in the embodiment due to the portal-shaped bracket 53, with which the cleaning device is held.
The portal-shaped bracket 53, together with the edge profile 2 a trolley, which is laterally movable on the cooling registers. The wagon carries all belonging to the cleaning device components, as they are already the subject of the earlier proposal. These include the example of a toothed belt drive (instead of belt drive can also chain hoist or other drawbar be provided with tape or rope), the drive and the nozzle floor carriage.
To process 53 driving rollers are provided at the bottom of the bracket. The castors have a detent in the form of a clamp. The details are shown in FIG.

Fig. 7 zeigt zugleich die Aufhängung des Kantprofiles 2 in den Bügeln 53. Als Aufhängung dient eine Verstrebung 54. Das Kantprofil 2 ist so angeordnet, daß eine Diagonale des Querschnittes vertikal verläuft.
Auf den geneigten Flächen des Kantprofiles 2 laufen Rollen 55. Die Rollen 55 sind an Blechstreifen 56 montiert. Die Blechstreifen 56 sind am oberen Ende so gekantet, daß die Befestigungsflächen für die Rollen 55 unter 90 Grad zueinander stehen. Den gleichen Winkel schließen die Seitenflächen des Kantprofiles 2 jeweils zwischen sich ein.Fig. 7 shows at the same time the suspension of Kantprofiles 2 in the brackets 53. As suspension is a strut 54. The edge profile 2 is arranged so that a diagonal of the cross section is vertical.
On the inclined surfaces of the Kantprofiles 2 run rollers 55. The rollers 55 are mounted on metal strips 56. The metal strips 56 are folded at the upper end so that the attachment surfaces for the rollers 55 are at 90 degrees to each other. The same angle, the side surfaces of the Kantprofiles 2 each between them.

An den unteren Enden der Blechstreifen 56 sind Bolzen 57 vorgesehen. Die Bolzen 57 bilden zugleich Abstandshalter für die Blechstreifen und auch Befestiger für den Düsenstock 50.At the lower ends of the metal strip 56 bolts 57 are provided. The bolts 57 at the same time form spacers for the metal strips and also fasteners for the nozzle 50th

Nach Fig. 8 ist zur Befestigung des Düsenstockes 50 an der durch die Bolzen 57 gebildeten Konstruktion eine Verschraubung vorgesehen. Die Verschraubung erlaubt eine schnelle Montage und Demontage. Hilfreich ist dabei, daß die zugehörigen Schrauben am Kopf einen Hebel besitzen, mit sich eine Schraubendrehung ohne Werkzeug von Hand bewirken läßt. Der Hebel ist in Fig. 8 mit 58 bezeichnet.According to FIG. 8, a screw connection is provided for fastening the nozzle assembly 50 to the construction formed by the bolts 57. The screw connection allows quick assembly and disassembly. It is helpful in that the associated screws have a lever on the head, with a screw rotation without tools can be done by hand. The lever is designated 58 in FIG.

Die Fig. 8 zeigt im weiteren den Riementrieb mit dem Zahnriemen 59 und verschiedene Riemenrollen 60 und 61. Ferner ist dargestellt, wie die Enden des Zahnriemens an dem Düsenstockwagen (bestehend aus Düsenstock, Rollen, Halterungen, Blechstreifen, Bolzen usw.) bei 62 und 63 angeschlagen sind.Fig. 8 further shows the belt drive with the timing belt 59 and various belt rollers 60 and 61. Furthermore, it is shown how the ends of the toothed belt on the nozzle floor carriage (consisting of nozzle, rollers, brackets, metal strips, bolts, etc.) at 62 and 63 are posted.

Fig. 8 zeigt auch eine Bremse mit einem federbelasteten Bremshebel 64. Der Bremshebel wird von der Spannkraft des Zahnriemens 59 außer Eingriff gehalten. Bei nachlassen der Spannkraft wird der Bremshebel gegen das Kantprofil 2 gedrückt. Zugleich bewirkt die entstehende Reigung ein Drehmoment an dem Bremshebel 64. Der Bremshebel 64 wird noch stärken in Funktion gebracht.Fig. 8 also shows a brake with a spring-loaded brake lever 64. The brake lever is held by the clamping force of the toothed belt 59 disengaged. When the tension decreases, the brake lever is pressed against the edge profile 2. At the same time, the resulting rectification causes a torque on the brake lever 64. The brake lever 64 is brought strengthen even more in function.

Der Bremshebel ist für die Wartungs- und Reparaturarbeiten an der Vorrichtung von Vorteil. Bei einem Auswechseln des Riemens sichert der Bremshebel 64 den Düsenstockwagen selbsttätig in der jeweiligen Stellung. Sonst besteht die Gefahr eines ungewollten unds schnellen Herunterfahrens des Wagens. Die Folge wird leicht ein Sachschaden sein.The brake lever is advantageous for the maintenance and repair work on the device. When replacing the belt, the brake lever 64 secures the nozzle floor carriage automatically in the respective position. Otherwise there is a risk of unwanted and quick shutdown of the car. The consequence will easily be a property damage.

In Fig. 8 sichert eine U-förmige Fahrschiene 65 die Reinigungsvorrichtung gegen ein unbeabsichtigtes Abheben vom Kühlregister. Die Fahrschiene wird nachträglich an den Kühlregistern angebracht.
Als seitlichen Verfahren der Reinigungsvorrichtung ist auch ein seitliches Gleiten der Reinigungsvorrichtung anzusehen. Dabei sind keine Rollen sondern Gleitkufen vorgesehen.In Fig. 8, a U-shaped running rail 65 secures the cleaning device against inadvertent lifting from the cooling register. The rail is attached to the cooling registers later.
As a lateral method of the cleaning device and a lateral sliding of the cleaning device is to be regarded. There are no rollers but skids provided.

In Fig. 9 ist der Fuß der Reinigungsvorrichtung in einer Draufsicht dargestellt.
Mit 66 sind weitere Rollen des Riementriebes bezeichnet, mit unterschiedlichen Funktionen, z.B. Umlenkfunktion und Spannfunktion und Antriebsfunktion. Die Antriebsrolle ist über eine Kupplung 67 mit einem Getriebemotor 68 verbunden.
Mit 69 ist die Wasserzuführung zum Düsenstock 50 bezeichnet.In Fig. 9, the foot of the cleaning device is shown in a plan view.
With 66 other roles of the belt drive are designated, with different functions, such as deflection function and clamping function and drive function. The drive roller is connected via a coupling 67 with a geared motor 68.
At 69, the water supply to the nozzle 50 is designated.

Fig. 10 zeigt die Teile der Fig. 9 in einer Seitenansicht.
Der Motor 68 und die verschiedenen Rollen 66 sind mit einer Haube 70 abgedeckt. Die Haube 70 ist schwenkbar gelagert und kann von Hand an einem Bügel 71 bewegt werden. Der Bügel 71 kann zugleich genutzt werden, um die Reinigungsvorrichtung von Hand seitlich zu versetzen. Dabei stellt sich wiederum das Problem des Gleichlaufes am oberen und unteren Ende. Wahlweise wird der Gleichlauf bei mechanischem Antrieb über eine geeignete Steuerung oder über eine Mechanik sichergestellt. Für die mechanische Gleichlaufsteuerung eignet sich auch ein Seilsystem mit einer Handkurbel. Dabei wird gesichert, daß das Seil zugleich die Fahrrollen am obern und unteren Ende bewegt. Das geschieht durch geeignete Umschlingung der Rollen.Fig. 10 shows the parts of Fig. 9 in a side view.
The motor 68 and the various rollers 66 are covered with a hood 70. The hood 70 is pivotally mounted and can be moved by hand on a bracket 71. The bracket 71 can be used at the same time to move the cleaning device laterally by hand. This in turn raises the problem of synchronism at the top and bottom. Optionally, synchronism is ensured in the case of mechanical drive via a suitable controller or via a mechanism. For the mechanical synchronization control is also a cable system with a hand crank. It is ensured that the rope also moves the rollers at the top and bottom. This is done by suitable wrap around the roles.

Fig. 11 zeigt eine Sicherung gegen Abheben der Vorrichtung mittels einer Rolle 75, die eine Fahrschiene hintergreift. Die Rolle 75 ist mittels einer Spindel 76 gehalten und so vorfahrbar und zurückfahrbar, daß die Rolle 75 in die Sicherungsstellung kommt oder aus der Stellung wieder herausbewegt wird. Die Spindel 76 ist mit einem Hebel oder Griffteller oder Rad verstellbar und in der jeweiligen Stellung arretierbar.Fig. 11 shows a backup against lifting of the device by means of a roller 75 which engages behind a running rail. The roller 75 is held by a spindle 76 and so vorfahrbar and retractable, that the roller 75 comes into the securing position or is moved out of the position again. The spindle 76 is adjustable with a lever or handle plate or wheel and can be locked in the respective position.

In einem nicht dargestellten Ausführungsbeispiel sind die Beine der Bügel 53 verlängerbar bzw. einkürzbar. Das geschieht wahlweise mit montierbaren oder demontierbaren Stücken oder durch Teleskopieren der Beine.In an embodiment not shown, the legs of the bracket 53 can be extended or shortened. This is done either with mountable or removable pieces or by telescoping the legs.
