Description 5

The invention relates to a bridge or gantry crane for the handling of standardized cargo carriers, in particular for the handling of ISO containers in the port area, with a along a crane carrier in Katzfahrtrichtung movable trolley, on a rigid and in a lifting and 0 lowering direction extending mast is performed, the at least one at the

Crane arranged hoist via ropes in the lifting and lowering direction is movable, at the lower end of a load-receiving means for standardized load carrier is attached, wherein the mast is rotatably suspended about a longitudinal axis extending in its longitudinal axis on the trolley. 5

European Patent EP 1 365 984 B1 discloses a bridge crane for stacking containers, in particular ISO containers, which stores containers within a container terminal in and / or out of a storage area. The bridge crane has a crane girder, which spans an essentially parallelepiped-shaped storage area in width. On the crane girder and along the longitudinal direction of a crane trolley in the width direction of the storage area is movable. The crane girder can be moved on trolleys on rails in the crane travel direction and thus transversely to the crane trolley on the crane girder and in the longitudinal direction of the storage area. In order to handle the container, a trolley 5 is arranged on the trolley, which is guided in the vertical direction and can be raised or lowered. The mast is designed as a box girder and hoists are arranged on the crane trolley for the lifting and lowering movement of the mast. At the bottom and in the direction of the container to be handled end of the mast a load-handling means for containers, in particular a so-called spreader, hinged. The load handling equipment is connected by cables to the hoists on the crane trolley. The mast is not directly driven in lifting and lowering direction but only indirectly via the acting on the load-carrying ropes. The use of a rigid mast between the trolley and the load-carrying means has the advantage that a pendulum-poor handling of the container in contrast to also used and 5 exclusively suspended on ropes lifting equipment is possible. From the German patent application DE 29 1 1 938 B2 a crane system for the handling of containers in rail transport is already known. This crane system is designed as a gantry crane, which has in the usual way a horizontally extending bridge girder on which a trolley is movable. This trolley carries a columnar mast which is vertically movable in a lifting and lowering direction. At the lower end of the mast, a load-carrying means for the container is attached. In order to rotate the load-carrying means and the mast about a vertical axis, the mast is eccentrically guided in the region of its upper end on an annular intermediate frame in which a central hoist is arranged, which is connected by ropes to the mast. The annular intermediate frame is movable in the direction of rotation via running gears on an annular rail, which is arranged on the trolley, and can thus rotate the mast, including the load-carrying means for the containers arranged thereon, about a vertical axis.

Furthermore, a device for handling containers in rail traffic is already known in the German utility model DE 200 13 245 U1, which is constructed in the manner of a column swivel crane. Correspondingly, this device has a vertical pedestal, at the upper end about a vertical axis pivotally a horizontally extending and cantilevered boom is arranged. At the end of the boom facing away from the pillar, a crane boom for a trolley traveling along it is suspended by means of a slewing gear with a vertical axis. This trolley carries a hoist and two vertically downwardly extending masts on which a lifting with the help of the hoist in lifting and lowering direction along movable. At the lower end of the carriage there is a load handling device for the containers.

Furthermore, from German patent application DE 27 52 212 A1 a transfer device for containers in rail traffic is known, which is designed substantially as a gantry crane with a trolley. On the trolley, a lifting device for the containers is suspended via a vertical column. The non-raised and lowered column is supported via a rotating device at its upper end on the trolley and can thus be rotated about its vertical axis of rotation. Furthermore, the load-carrying means is suspended by hoists to a small extent in the lifting and lowering movable to the lower end of the mast. The present invention has for its object to optimize a bridge or gantry crane with a rigid boom for an envelope of normalized charge carriers, in particular ISO containers in port handling.

This object is achieved by a bridge or gantry crane with the features of claim 1. Advantageous embodiments of the invention are specified in claims 2 to 6.

According to the invention a bridge or gantry crane for the handling of standardized cargo carriers, in particular for the handling of ISO containers in the harbor area, with a along a crane carrier in Katzfahrtrichtung movable trolley on which a rigid and extending in a lifting and lowering mast out is, which is movable over at least one arranged on the trolley hoist ropes in the lifting and lowering direction, at the lower end of a

A load-carrying means for standardized load carrier is attached, wherein the mast is suspended about a longitudinal axis of rotation extending rotatably mounted on the trolley, an optimization of the application possibilities achieved in that is hung on a rotating assembly on the trolley, the lifting frame, which carries the at least one hoist, the Rotary assembly consists essentially of a rotary tube having an upper end and a lower end, the rotary tube is supported at its upper end via a rotary connection to the trolley, that at the lower end of the rotary tube of the lifting frame is fixed and that in the rotary tube and coaxial with the rotary tube of the mast is raised and lowered guided. This makes it possible to align normalized carriers depending on requirements within a transhipment facility in any angular positions to facilitate further transport. The creation of a lifting frame next to the trolley divides their functions among each other. The attachment of the lifting frame at the lower end of the rotary tube leads to a stable unit of ropes, hoist and mast and makes this in itself as a swivel. By this arrangement is also achieved that a rotation of the mast can be made together with the load-receiving means relative to the trolley.

The fact that the lifting frame is arranged below the crane girder, it is achieved that the lifting frame can be pivoted under the crane girder through and the swivel angle is not hindered by the crane girder.

A particularly stable support of the mast and the rotating device is achieved in that the crane girder consists of a first carrier and a second carrier, on which Katz rails are arranged, on which the trolley is moved in Katzfahrtrichtung, the first carrier and the second carrier in the perpendicular to the Katzfahrtrichtung running crane travel direction is spaced apart and the mast between the first carrier and the second carrier extends.

A direct introduction of the lifting forces in the load-carrying means is achieved in that the ropes of the lifting gear on the load-receiving means attack. The mast takes over the management tasks.

A particularly stable suspension of the lifting device is achieved in that at least four cables are provided, the ends of which act in the region of the corners of the substantially rectangular load-bearing means.

Advantageously, it is provided that the load-receiving means consists of a suspension frame and a spreader frame suspended thereon, the

Hanging frame is hinged or rigidly attached to the lower end of the mast and attack the ropes on the hanger frame.

An embodiment of the invention is illustrated in the drawing and will be described below. Show it:

FIG. 7 shows a detail enlargement of FIG. 3 from the area of a rotary joint.

FIG. 1 shows an overview of a handling installation 1 in a port area in which containers 2, in particular ISO containers, are handled. The overview map shows only a part of the transhipment installation 1, but reveals its essential components. The handling installation 1 consists of a land-side transshipment area 3, a container storage 4 and a sea-side transshipment area 5.

The land-side cover area 3 adjoins a landseitiges end 4a of the container storage 4 and has a subsequent loading and unloading area 6 with a plurality of juxtaposed spaces 7 for loading and unloading trucks 8. In the loading and unloading area 6, a lorry 8 parked on one of the parking spaces 7 is loaded or unloaded by a bridge or gantry crane 9 operating in the container storage 4.

The container storage 4 consists of a plurality of parallel side-by-side and row-like arranged container storage areas 4c, each of which at its land-side end 4a a loading and unloading area 6 and 4b is assigned at its sea-side end a storage and retrieval area 10. Each container storage area 4c is assigned one or more bridge or gantry cranes 9, which can be moved along the container storage areas 4c in the crane traveling direction F on rails 11. From the bridge or gantry crane 9, the container 2 between the container storage area 4c and the loading and unloading area 6 and the Transport and removal area 10 transported. Each container storage area 4c has, in addition to the one or more bridge or gantry cranes 9, a storage area 4d for the containers 2. The storage area 4d has a rectangular base area on which the containers 2 are arranged in columns and rows. Here, up to five containers 2 are stored stacked on top of each other. The parked container 2 are aligned with their longitudinal extent substantially parallel to the rails 1 1 and thus in crane travel direction F of the bridge or gantry cranes 9. This orientation of the container 2 can also be found in the loading and unloading area 6 with the arriving and departing trucks 7, so that the bridge or gantry cranes 9 in addition to any necessary alignment corrections, the container 2 do not have to pivot during recording and delivery. At the seaward end 4b of the container storage 4, the containers 2 are parked by the bridge or gantry crane 9 in the storage and retrieval area 10 or taken from there. The storage and retrieval area 10 serves as an interface to the seaward cargo area 5 and has a plurality of juxtaposed supporting frames 7a for container 2, can enter into the driverless transport vehicles 15 with an unrecognizable lifting table to accommodate the stored there intermediate container 2 or park there. It is also possible that the container 2 are received directly by means of the bridge or gantry crane 9 of the platform or parked there. Then no supporting frames 7a are present and the driverless transport vehicles 15 have no lifting tables.

FIG. 2 shows an enlarged detail of FIG. 1 from the area of loading and unloading area 6 and part of an adjacent container storage area 4c. It can be seen that in each loading and unloading area 6 several parking spaces 7 for trucks 8 are arranged side by side and with the smallest possible distance from each other. Furthermore, the closer construction of the bridge or gantry crane 9 can be seen from FIG. There are two bridge or gantry cranes 9 shown on common rails 11. This bridge or gantry crane 9 consists essentially of a along the laterally adjacent to the storage areas 4d of the respective container storage area 4c arranged rails 11 in crane traveling direction F crane crane 12, on the transverse direction of travel F of the crane girder 12 a crane trolley 13 in Katzfahrtrichtung K is movable. On the trolley 13, a mast 14 is arranged and vertically and relative to the trolley 13th Can be raised and lowered to record and deliver by means of a at its lower end 14a, (see Figure 3) attached to the load receiving means 17, preferably a Spreaderrahmen container.

In order to rotate the container 2 by 180 degrees about a vertical axis, the bridge and gantry crane 9 is equipped with a rotating device 16. With the turning device 16, the orientation of the container 2 can be changed over the bridge and gantry crane 9 so that the doors of the container 2 arranged only on one side at a longitudinal end of the container 2 point in the desired direction. It can thereby be avoided that the transport vehicles 15 have to make the time-consuming turning of the container 2. Also, the rotating device 16 may be used to park the containers 2 at an angle of, for example, 30 degrees to the crane travel direction K on the trucks 7 and / or the transport vehicles 15 when the parking spaces 7 and / or the supporting frames 7a are arranged at an angle to the crane traveling direction K. are.

FIG. 3 shows a view of a transhipment installation with a bridge or gantry crane according to the invention in the form of a gantry crane. It can be seen that the load-carrying means 17 is divided into a suspension frame 17a, which is gimbal-mounted or fixed to a lower end 14a of the mast 14, and in a

Spreaderrahmen 17 b, which is suspended by chains 17 c on the suspension frame 17 a.

Furthermore, the crane girder 12 is supported at its opposite ends by right and left vertical supports 181 and 18r viewed in the crane traveling direction F. Overall, the bridge or gantry crane 5 seen in crane travel direction U-shaped and open at the bottom. The vertical supports 181 and 18r receive the crane girder 12 at their upper ends, at their opposite end regions, and can be moved at their lower ends by crane gantries 19 on the rails 11 in the crane travel direction F.

The trolley 13 consists essentially of a rectangular base frame 13a, in its four corners Katzfahrwerke 21 are arranged, which moved on the crane girder 12 arranged cat rails 20. In the base frame 13a of the trolley 13 is located in the central region an opening for a rotating device 16 for the mast 14. The rotating device 16 consists essentially of a rotary tube 16a, which is guided through the opening in the vertical direction. The rotary tube 16 a is supported at its upper end 16 b via a rotary joint 16 c on the base frame 13 a of the trolley 13 and is rotatable about the rotary joint 16 c about a vertical axis of rotation D. Within the rotary tube 16 a of the mast 14 extends and is guided there.

FIG. 4 shows a side view of FIG. 3. It can be seen that the crane girder 12 is designed as a double girder with a first girder 12a and a second girder 12b which, viewed in the crane running direction F, are arranged at a height level and at a distance one behind the other. Correspondingly, the left vertical support 181 and the right vertical support 18r seen in crane running direction F are formed as double supports, which are connected to each other in the region of their lower end U-shaped via a base support 18a.

FIG. 4 also shows that the first carrier 12a and the second carrier 12b each have a triangular cross-section. This triangular cross section has the shape of an isosceles triangle, wherein the angle in the region of the tip 12c is about 30 °. In the area of the tip 12c of the first carrier 12a and the second carrier 12b, the cat rail 20 is fixed in each case, on which the crane trolley 13 can be moved in the trolley travel direction K.

FIG. 4 clearly shows the rotary joint 16b and the rotary tube 16a. For driving the rotary tube 16a, a ring gear 16f circulating on its outside is provided, which engages with a rotary electric drive 16g which is supported on the base frame 13a. In order to move the mast 14 in the lifting and lowering direction H, a rectangular lifting frame 22 is rigidly attached to a lower end 16d of the rotary tube 16a. On the lifting frame 22 of the trolley 13, a hoist 23 for the mast 14 is arranged. The hoist 23 has a first cable drum 23a and a second cable drum, not shown, which are coaxial with each other and mounted on a common gear 23b, which is driven by a drive motor 23c. From the first cable drum 23a, a first cable 24a and a second cable 24b run off. From the second cable drum 23b, a third cable 24c and a fourth cable 24d run off. Correspondingly, there are four cables 24a, 24b, 24c and 24d, either directly from the first or second cable drum 23a, 23b drain down vertically or horizontally on the opposite side of the mast 14 are guided and deflected there by a deflection roller 25 with a horizontal axis of rotation by 90 ° vertically downwards. The ends of the cables 24a, 24b, 24c and 24d are connected to suspension frames 17a.

Also, Figure 4 shows that on the outside of the second support 12b, a container-like container 26 is fixed, in which the control and power electronics or electronics for the bridge or gantry crane 9 is arranged.

FIG. 5 shows an enlarged detail of the bridge or gantry crane 9 according to FIG. 1 from the region of the crane trolley 13. From this sectional view, it can be seen in particular that the mast 14 in each case via lower guide elements 28a in the region of the lower end 16d of the rotary tube 16a and above Guide elements 28b in the region of the upper end 16c of the rotary tube 16a is guided. The lower and upper guide members 28a and 28b are formed as guide rollers which guide the mast 14 and each from four sides and opposite. The mast 14 has an elongated hexagonal cross section for reasons of stability.

Furthermore, it can be seen clearly from FIG. 5 that the trolley 13 does not carry the hoists 23 as in the usual way, but instead a separate lifting frame 22 is provided which is rotatably suspended by a rotary device 16 on the trolley 13 with the trolleys 21 , On the lifting frame 22 then the hoist 23 and associated pulleys 25 (see Figure 4) are arranged. This has the advantage that the lifting frame 22, the lifting mechanism 23 arranged thereon with the deflection rollers 25, the mast 14, the load receiving means 17 and the first to fourth cables 24a to 24d extending between the lifting frame 22 and the load receiving means 17 together about the rotation axis D. are pivotable. Thus, these parts form an inherently stable unit, which further excellently carries the load-receiving means 17 against lateral deflections.

FIG. 6 shows an enlarged detail of FIG. 5 from the region of the crane trolley 13 or the rotary device 16. It can be seen that the rotary device 16 has, in addition to the rotary tube 16a, a circular tubular support tube 29 which surrounds the rotary tube 16a coaxially and at a distance. This support tube 29 is supported on the base frame 13 a of the trolley 13. The support tube 29 serves with its upper end 29a as a support for a rotary joint 16b in the form of a roller bearing. On this rotary joint 16b then the rotary tube 16a is supported in the region of its upper end 16c, thereby a total of a stable connection of the trolley 13 is achieved with the lifting frame 22, with which the lateral guiding forces of the mast 14 can be accommodated.

The description refers to a bridge or gantry crane 9, which is designed as a gantry crane. In principle, it is also possible to form the bridge or gantry crane 9 as a bridge crane with raised or elevated rails 1 1 or half gantry crane. In addition, the embodiment is based on the ISO container handling in the port area. This bridge or gantry crane 9 is also suitable for the handling of standardized load carriers, such as ISO containers or swap bodies, between road and rail.
