Novel lifting appliance for transporting passenger car body

Abstract

The invention provides a novel lifting appliance for transporting a passenger car body. The novel lifting appliance comprises a lifting appliance body and a lifting eye device, wherein the lifting appliance body comprises a main framework and a lifting ring connected with the main framework through a lifting chain; the main framework comprises four lifting points; the lifting eye device comprises lifting claws arranged on the lifting points respectively; lifting point slings are also arranged on the lifting points; each lifting point sling is connected with a U-shaped support through a connecting ring. The novel lifting appliance has the advantages that complete dependence on the upper part side window structure of the passenger car body is avoided; the strength pressure on the upper part side window structure is reduced; the novel lifting appliance is suitable for passenger car bodies with arc side windows, and convertible and semi-convertible sightseeing buses; the lifting requirements of passenger car bodies of almost all structures can be met approximately. Moreover, due to the arrangement of the U-shaped support device, the stability of the passenger car body when the passenger car body is lifted up is enhanced; friction between the lifting belts and the skin of the passenger car body is avoided. Furthermore, manual moving is avoided during the lifting process, so that the labor efficiency is greatly improved, and the potential safety hazard is reduced.

Description

technical field [0001] The invention relates to special equipment for transfer and hoisting of vehicles, in particular to a spreader for transfer and hoisting of passenger car bodies. Background technique [0002] With the development of bus technology and scale, the transfer and lifting of bus body has become an inevitable process. For example, all the fastening of semi-loaded vehicles requires the lifting of the body; many passenger cars have several branch factories, which generally focus on one area for electrophoresis of the entire vehicle, and the body needs to be lifted for transfer. At present, the spreader commonly used in the passenger car industry is a pneumatic eight-claw spreader or a manually adjustable four-claw spreader, which are all lifted from the side window along the grab hook. These spreaders have the following problems: [0003] 1. It is not suitable for the full-loaded body: because the full-loaded truss structure chassis frame and the body are in...

Problems solved by technology

[0005] 3. It is not suitable for the body with curved side windows: There are many models on the market at present. In order to increase the internal lighting, the side windows adopt a curved structure, that is, the upper edge of the side window of this structure is on the big roof, so the four claws cannot grasp it at all. On the one hand, the adduction width is too narrow, on the other hand, the four-claw hook interferes with the top skin, which is easy to pierce the top skin;

[0006] 4. Sightseeing cars cannot be used: At present, many sightseeing cars adopt open-top or semi-open-top structures. The upper part of the bus body of this structure has no side windows, and the four-claw and pneumatic eight-claw spreaders have no hook points at all;

[0007] 5. Poor versatility: due to the non-adjustable structure or small adjustment range of the lengthwise distance and widthwise distance of each claw of the four-claw spreader and the pneumatic eight-claw spreader, and the structure of the current market models is changeable, it is often encountered that claws and Window column interference phenomenon, resulting in unusable spreader
