Special lifting appliance of side wall of coal conveying open wagon

Abstract

The invention discloses a special lifting appliance of the side wall of a coal conveying open wagon. The lifting appliance comprises a double-buckle flexible lifting belt, a high-strength bolt connecting pair, an installing and clamping groove body and a clamping block; the double-buckle flexible lifting belt is connected with the installing and clamping groove body through the high-strength boltconnecting pair, and the high-strength bolt connecting pair comprises a screw rod and a nut; the installing and clamping groove body is of a double-clamping-groove structure and comprises a large clamping groove and a small clamping groove, a square opening through hole is formed in the center position, close to the front, of the top of the installing and clamping groove body, two pairs of ear plates are fixedly arranged on the positions, near the rear part, of the top of the installing and clamping groove body in a left-and-right symmetrical mode, and through holes matched with the screw rodof the high-strength bolt connecting pair are orrespondingly formed in the opening end parts of the ear plates and the opening end parts of the double-buckle flexible lifting belt respectively; the screw rod penetrates through the through holes of the ear plates and the through holes of the double-buckle flexible lifting belt; and the clamping block penetrates into the square opening through holein the top of the installing and clamping groove body. The special lifting appliance is small in structure, light in weight, convenient to operate and capable of greatly reducing the labor intensity during lifting of an operator, the production time is shortened, the production bottleneck is overcome, and the production efficiency is improved.

Description

Technical field: [0001] The invention relates to the technical field of vehicle manufacturing, in particular to a special spreader for the side wall of a gondola car for coal transportation. Background technique: [0002] At present, in the railway wagon manufacturing industry, the side walls of the wagon are generally hoisted and assembled with a beam spreader. In the prior art, the large assembly line of the gondola car body of the relevant manufacturer is designed and manufactured based on the 70T class gondola car, and the side walls are hoisted and assembled by overhead lifting with a beam spreader, while the height of the side walls of the C80B stainless steel gondola car The 70T level side wall is more than 1 meter high. If the original side wall spreader is still used for hoisting, there will be interference between the top guardrail and clamps of the assembly line and the side wall, and the side wall cannot pass the top, so the beam spreader cannot meet the requirem...

AI Technical Summary

Problems solved by technology

Therefore, it is urgent to design a special spreader with miniaturization and light weight to solve the problem of interference between the side wall hoisting overhead and the general large assembly line
