New passenger car body transfer spreader

Abstract

The invention provides a novel passenger car body transfer spreader, which includes a spreader body and a lifting lug device, the spreader body includes a main frame and a lifting ring connected to the main frame through a lifting chain; four lifting points are arranged on the main frame , the lifting lug device includes lifting claws respectively arranged on each lifting point; the lifting point is also provided with a lifting point sling, and the lifting point sling is connected to a U-shaped lifting device through a connecting ring. The present invention avoids all dependence on the upper side window structure of the passenger car body, reduces the structural strength pressure of the upper side window, and is suitable for the body with curved side windows, as well as open-top and semi-open-top sightseeing cars, and basically meets all requirements. Structural bus body lifting requirements. At the same time, the setting of the U-shaped lifting device strengthens the stability when lifting the vehicle body and avoids friction between the suspenders and the skin of the vehicle body. In addition, manual movement is avoided during the lifting process, which greatly improves labor efficiency and reduces potential safety hazards.

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 inte...

AI Technical Summary

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
