Definitions

  • a device for surface treatment which consists of a chassis, a blasting chamber with a surface treatment device and a mast boom.
  • a hydraulic device With a hydraulic device, the processing angle of the boom with respect to the vehicle frame and that of the blasting chamber with respect to the mast can be changed.
  • a device for a surface treatment is also known from DE-A-36 29 623 A1. It consists of a chassis with a support and a cabin mounted on the support. The cabin is open on the side facing the property and is provided with sealing elements all around. A centrifugal wheel is arranged inside the cabin. Aircraft bodies are cleaned and blasted. The used abrasive is reprocessed by a connected abrasive preparation system. In order to be able to travel along the surface with the cabin, the support in the chassis can be pivoted from 0 - about 90 ° and the cabin on the mast about its axis by about 270 °.
  • the invention has for its object to provide a device for surface treatment of large exposed substantially horizontal surfaces of objects, in particular ships, which enables simple and safe handling.
  • the object is achieved in that a scissor joint device with an overlying three-dimensionally movable spring-joint device is arranged between the chassis and the blasting capsule.
  • the advantages achieved by the invention when machining an essentially straight horizontal or horizontal bottom area of a ship consist in particular in that it is possible to move as far as possible to the bottom surface under the ship, to direct the blasting capsule to the bottom area and to use the spring Press the hinge device precisely onto it. It is thus possible that the surface treatment device inside the blasting capsule can easily, reliably and precisely grasp the entire floor area and process it accordingly. If the area of the bottom of the ship corresponding to the size of the blasting capsule is treated, the next area is treated by moving the chassis. So this way treated the entire difficult to access surface of the bottom of the ship.
  • the scissor joint device consists of a scissor-type frame, which is composed of scissor bar elements movable in scissor and / or scissor pivot points, a scissor base element and an upper scissor element. This makes it possible to guide the blasting chamber vertically upwards from the vehicle plane to the bottom of the ship.
  • hydraulic cylinders instead of the scissor-type joint device, which are actuated individually in coordination with one another.
  • the universal joint is connected to the center of the scissor element and the springs are connected to the lower periphery of the blasting capsule.
  • the blasting capsule thus held and sprung can adapt to any curvatures or deformations of the bottom of the ship when it is pushed up, so that it is ensured that all parts of the very large floor area are treated effectively and sufficiently.
  • roller elements are arranged opposite the springs. These roller elements ensure that the blasting capsule can be moved along the surface of the ship's floor.
  • blasting capsule with the scissor-joint device and the spring-joint device are arranged in front of a driver's cabin. This enables the operator to control the precise manner and level of the process of the blasting cabinet.
  • the blasting capsule is connected to a suction delivery hose and at least one blasting agent hose on the surface treatment device designed as a blasting nozzle with an oscillator drive.
  • This ensures that the blasting process takes place dust-free and that the blasting medium is circulated and processed.
  • this allows blasting with multi-way blasting media - preferably with steel blasting media.
  • single-use blasting media usually copper slag - this steel blasting media can be reused up to two hundred and fifty times.
  • the blasting process as a whole is environmentally friendly and, in particular, considerably more economical.
  • the blasting capsule is surrounded on its open side with sealing elements. These sealing elements ensure that the blasting agent is held within the blasting cubicle and suctioned off accordingly. It is advantageous if the sealing elements are a combined rubber / brush cover. This ensures that when the Blasting media can draw enough air without blasting media leaving the blasting chamber. It has proven to be advantageous if the combined rubber / brush cover is additionally provided with magnets. These magnets ensure that the seal clings tightly and intimately to the surface of the surface to be treated in this case the ship's bottom.
  • the driver's cabin is not higher than the uppermost point (sealing elements 23) of the lowered blasting capsule.
  • the chassis is advantageously moved forward by chains.
  • wheels or the like instead of the chains.
  • the selected dimensions ensure that the entire device can move freely and safely under the ship's floor.
  • the palls are arranged according to a ship-specific pale plan. This is related to the ship's statics. Since ships are to be blasted and coated at regular intervals, the pads are arranged at a different location during a subsequent anti-corrosion treatment and then the previously occupied location is blasted.
  • the pads 4.1, ... 4.n are arranged accordingly offset.
  • FIGS. 3 to 5 A blasting device which can be used for the bottom region 1.4 is shown in FIGS. 3 to 5.
  • the chassis 20 is freely movable by a chain undercarriage 11.
  • a driver's cabin 7 is located above the chain undercarriage 11, in which the driving lever 8 and a seat element 15 are arranged.
  • a lamp 6 is installed on the driver's cabin 7.
  • a motor drive 5 is located in front of a window element 17.
  • a scissor base element 18 is arranged on the chassis 20 in front of the driver's cabin 7.
  • a scissor upper element 28 is arranged above the scissor bar elements 25.1, ... 25.n.
  • the first scissor bar element 25.1 is rotatably and longitudinally displaceable in an elongated hole 30 of the scissor base element and the last scissor bar element 25.n in a slot recess 31 of the scissor upper element is likewise arranged so as to be rotatable and longitudinally movable, while the second scissor bar element 25.2 and the penultimate scissor bar element 25.n. -1 in the second or penultimate scissor pivot point 26.2 or 26.n-1 on the scissor base element 18 or on the scissor upper element 28 can only be rotated.
  • the upper scissor element 28 is in its center Z 'over a Cardan joint 29 connected to the center Z of a smooth element 19.
  • springs 12.1, 12.2 are arranged, which are attached with their opposite side to the lower periphery P 'of the blasting capsule 22.
  • roller elements 24.1 and 24.2 are fastened on the other side. It is possible to attach the rollers 24.1, 24.2 to all four corners of the blasting chamber 22 or in the middle thereof. Whether two, four or more roles are used depends on the respective application.
  • the essentially open side of the blasting capsule 22 is surrounded by sealing elements 23.
  • Combined rubber / brush seals which are additionally equipped with permanent magnets, are advantageously used here. This measure ensures that the blasting capsule 22 clings very intimately to the bottom of the ship and prevents individual steel grains from escaping.
  • One or two oscillating jet nozzles 21.1 and 21.2 are arranged in the blasting chamber 22 itself. Your location is preferably selected so that the cleanest possible surface can be created during the blasting process. Both blasting nozzles 21.1 and 21.2 are connected to a blasting hose 10.
  • a vacuum suction system 14 and a blasting medium delivery hose are provided in order to be able to extract the blasting medium after blasting.
  • the blasting agent conveying hose 9 and the blasting hoses 10 are connected to a blasting preparation system.
  • the self-propelled blasting device described in this way is suitable for processing not only the bottom area of a ship, but also other essentially flat, large areas.
  • the chassis 20 is positioned below the ship wall 2 of the floor area 1.4 by the operator sitting in the driver's cabin 7. Since the blasting capsule 22 can be moved and resiliently supported on both sides in the universal joint 29 and the springs 12.1 and 12.2 and can be displaced upwards on the movable scissor linkage 13, it is adjusted upwards at a driving speed of preferably 0 to 6 m per minute and at the Surface of the ship's floor positioned in the floor area 1.2. The mobility of the blasting capsule 22 on the ship's floor is expanded by the roller elements 24.1 and 24.2, which also function as spacers.
  • the blasting power itself depends on the nature of the surface to be blasted or on the required degree of purity. On average, beam outputs of up to 20 m 2 / hour are realistic.
  • the jet nozzles 21.1 and 21.2 are fastened in the jet capsule in such a way that they are oscillating via a lifting rod and can be moved laterally in a jet path of 800-1000 mm.
  • the oscillation speed is about 20 m / min. This ensures good coverage.
  • the blasted blasting medium - preferably blasting blasting medium - and the dedusting via the vacuum system 14 are carried out with an integrated filter via the suction conveyor hose 9.
  • a mechanical pre-separator which also functions as a cleaning section, is interposed between the blasting capsule 22 and the flexible, highly abrasion-resistant suction delivery hose 9.
  • the blasting agent cleaned in this way gets back into a pressure blasting container and is removed from there out via the blasting hoses 10 back to the blasting nozzles 21.1 and 21.2 in the blasting capsule 22.
  • the blasting capsule 22 is adequately secured to the blasting surface of the ship's wall 2 in the floor area 1.4 by the circumferential sealing elements 23 such that, on the one hand, no blasting agent can escape from the blasting capsule 22 and, in addition, sufficient air is drawn into the capsule from the outside by the high vacuum of the suction conveyor system. It is essential that the entire blasting process takes place dust-free and that the blasting medium is circulated and processed. As a result, it is advantageously possible to use a reusable blasting medium, preferably steel blasting medium, instead of the previously used one-way blasting medium. In contrast to single-use blasting media - usually copper slag - the steel blasting media can be reused up to two hundred and fifty times.
