Description

A vehicle-mounted self-loading and unloading mechanism

technical field

The utility model belongs to the technical field of vehicle equipment, in particular to a vehicle-mounted self-loading and unloading mechanism.

Background technique

At this stage, many factories and freight stations have been expanded, but generally new factories are located in development areas on the fringes of cities. For example, due to partial updates of technology and production equipment in many companies, the production workshops of parts are not in the same place as the newly built general assembly workshops. Therefore, it is impossible to directly use forklifts to realize transportation between factories. In response to the above situation, most companies currently use small and medium-sized trucks to transport parts between the old and new factories. There are two main loading and unloading methods: one is to use a forklift to load at the starting point, and then use a forklift to unload at the end point. However, the loading and unloading process of this method requires the cooperation of transport vehicles and forklifts. The work process is relatively cumbersome, and the total cost of the required equipment is relatively high; However, when this method is used for loading and unloading operations, at least two loading and unloading workers are required to work at the same time, which is laborious and time-consuming, and there are great potential safety hazards.

The use of self-loading trucks can well solve the problems existing in the existing loading and unloading methods, but there are few types of existing self-loading trucks, and most of them are designed for larger trucks. The modification of the body is very large and the cost is extremely high, so it cannot be applied to the modification application of small transport trucks. The Chinese patent application number 201220733299.8 discloses a self-loading truck with a telescopic swing arm mechanism loading and unloading truck. The horizontal axis is movably connected with the left swing arm and the right swing arm. The inside of the left swing arm and the right swing arm are respectively inlaid with copper slide plates and telescopic oil cylinders. The telescopic oil cylinders are fixed inside the left swing arms and right swing arms by bolts. It is threadedly connected with the telescopic arm, and the piston rod of the telescopic oil cylinder drives the telescopic arm to move along the surface of the copper slide plate during operation. Although this patent effectively expands the loading and unloading position range of the box body compared with the prior art, it still requires at least two loading and unloading workers to cooperate with the operation, and it is impossible for a single person to hang the goods on the hooks of the two booms, and it is very difficult for loading and unloading. Personnel themselves have potential safety hazards. Therefore, a new structure is needed to solve the above problems.
