Description

Technical field:

[0001] The present application relates to the technical field of slings, and in particular to a special sling for large-tonnage crawler beams. Background technology:

[0002] The crawler beam generally includes a U-shaped beam body, one end of which is eccentrically provided with a guide seat, and the other end of the beam body is provided with a driving wheel seat. After the assembly is completed, the crawler beam is lifted to the predetermined position using a lifting device.

[0003] A construction machinery driving wheel seat hoist with application number 201420048486.1 comprises a shackle lifting plate and a lifting body connectable to the driving wheel seat, wherein the lifting plate is connected to the lifting body; a lifting hole is provided on the lifting plate, and the shackle is installed in the lifting hole; when the hoist lifts the driving wheel seat, the line connecting the lifting hole and the center of gravity of the driving wheel seat is parallel to the bottom plate of the driving wheel seat.

[0004] This patent hoists the driving wheel seat, but for the large-tonnage crawler beam that has been assembled, two slings are required, each sling is connected to a sling, one of which is placed at the guide seat and the other is placed at the driving wheel seat. However, since the guide seat and the U-shaped beam body are relatively eccentrically arranged, the hoisting will be unstable and there will be a great safety hazard. Another way is: one end uses the patented sling, and the other end is hoisted by the cooperation of a wire rope and a U-shaped lifting ring. The steps are as follows: after passing the wire rope with the U-shaped lifting ring body through the bottom of the crawler beam, the wire rope is fixed in the cavity of the U-shaped lifting ring through a pin shaft. Since the cooperation between the wire rope and the U-shaped lifting ring is relatively free, if the wire rope is not placed correctly, it will cause the wire rope to slide along the axial direction of the crawler beam, causing the crawler beam to fall and endangering the personal safety of workers. Utility model content:

[0005] In order to solve the above technical problems, the utility model provides a special lifting device for large-tonnage crawler beams, and solves the technical problem that the lifting of large-tonnage crawler beams is unstable, which poses a great safety hazard.

[0010] A U-shaped frame, wherein the horizontal section of the U-shaped frame is connected to the lower end surface of the hanging plate in a fixed structure manner, and a through hole is opened on the side wall of the U-shaped frame;

[0011] A support rod adapted to the through hole in a sliding structure;

[0012] A locking structure is connected to the U-shaped frame to fix the support rod.
