(54) DEVICE FOR TRANSFERRING THE CRANE TO RELATED CRANES

I

FIELD OF THE INVENTION The invention relates to a lifting and transport machinery, namely, devices for converting cranes to adjacent crane tracks.

A device for transferring a crane to another object is known, which contains a calf with longitudinal beams on which a rail track and screw stops 1 are mounted.

A disadvantage of the known device is the laboriousness of transferring the crane to the adjacent crane runways.

A device for transferring a crane to adjacent crane runways is known, comprising a carriage with longitudinal beams on which a track 2 is mounted.

A disadvantage of the known device consists in the inaccuracy of the docking of the rails of the trolley and runway path.

The purpose of the invention is to provide accurate docking of the carriage rails and crane runway.

To achieve this goal, the longitudinal beams of the trolley are made of separate sections with the possibility of moving one of them.

FIG. 1 shows schematically the proposed device, a general view; in fig. 2

Section A-A in FIG. one; in fig. 3 shows a section B-B in FIG. 2; in fig. 4 is a view B in FIG. one.

The device for converting a gantry crane comprises a carriage 1, a rail track 2, supporting concrete walls 3.

The cart has leading rollers 4 with drives 5, driven rollers 6, intermediate rollers 7, crane beams 8 with rails 9. At the base of crane girders there are screw stops 10, end stops 11 are mounted at the ends of the rails. The crane beams are interconnected by connecting beams 12, which consist of two sections, with the possibility of moving one of them by

 screws 13. To ensure rigidity of the structures, the sections of the connecting beams are fastened with overlays 14 with bolts 15.

Metal plates 16 are laid on the surface of the supporting concrete walls 20. The crane rails 17 of the gantry crane 18 are placed adjacent to each other.

The device works as follows.

When converting the gantry crane 18 to the adjacent crane runways, the traverse trolley 1 is aligned with the rail tracks 17. The rails 9 of the crane beams 8 are lined with the rails of the crane rails and the sections of the connecting beams 12 are centered with screws 13, after which they are fixed with bolts 15 The screw stops 10 are lowered to the contact with the plates of the 16 supporting concrete walls 3. The gantry crane is moved from the crane runways to the carriage rail to the end stops P. The crane is attached to the rails of the crane locks, the screw stops are raised ie, the release liner, and traverse trolley gantry crane moves into adjacent podkranovsh way. The transfer of the crane from the tracks of the traverse trolley to the main crane tracks is made in a similar way.
