Shelf push-and-pull turnover vehicle

Abstract

The invention discloses a push-and-pull shelf turnover vehicle. The vehicle comprises a bottom frame, side frames, a top frame, fixed shelves, guide frames, a movable shelf, lug plates, positioning rods, universal wheels, fixed rolling wheels and movable rolling wheels, the universal wheels are installed at the four corners of the bottom frame, a plurality of rows of fixed shelves are fixed between the two side frames, the two guide frames are symmetrically fixed to the upper ends of the fixed shelves and the bottom frame, the movable shelf is limited between the two guide frames in a slidingmode, a plurality of sets of lug plates are fixed to the upper end of the movable shelf, and the positioning rods are connected among the lug plates; and guiding sliding grooves are formed in upper side plates and lower side plates of the guide frames, the fixed rolling wheels are rotationally supported in the fixed shelf and the bottom frame, and the movable rolling wheels are rotationally supported in the movable shelf. When large-size materials are loaded and unloaded, personnel operation does not make contact with or interfere with the tote cart body any more, and the loading and unloadingefficiency is improved; and the risk that the materials collide with the turnover vehicle to be scratched is reduced, the installing quality is improved, and the quality risk of an engine caused by the fact that the cleanliness of key parts exceeds the standard is reduced.

Description

technical field [0001] The invention relates to the technical field of engine production equipment, in particular to a turnover vehicle with pushable and pullable layers. Background technique [0002] Turnover cart is an indispensable tool in production and has the characteristics of reusability. Most of the material delivery and transportation in the engine assembly workshop are carried out by turnover vehicles. [0003] There are deficiencies in the use of existing turnover cars: [0004] 1) The shelves for storing materials on each floor cannot be moved. When storing large materials such as crankshafts, the operating space is narrow, and the iron plates on both sides of the turnover car will inevitably hinder personnel from storing materials; on the one hand, the operating time of personnel is reduced. increase, resulting in unnecessary waste, on the other hand, if there is a bump, it will increase the risk of scratches and defects on the surface of the parts, which wil...

AI Technical Summary

Problems solved by technology

If the cleanliness of pistons, connecting rods, and crankshaft journals cannot be guaranteed, it is likely to cause lava in the engine, resulting in greater safety accidents

[0006] 3) For parts that need to be selected in groups, such as cylinder liners, if they are stored in existing turnover cars, the same cylinder liner must use two turnover vehicles considering different group factors, which takes up a large production space and will occupy an extra turnover vehicle , causing waste
