Automatic loading and unloading device for vehicles and automatic loading and unloading vehicle

Abstract

The invention relates to an automatic loading and unloading device for vehicles and an automatic loading and unloading vehicle. The automatic loading and unloading device comprises a lifting mechanism and a loading and unloading mechanism, wherein loading and unloading mechanisms are connected to the two sides of the lifting mechanism respectively and comprise a main oil cylinder, a landing gear and a supporting connecting rod respectively; the landing gear comprises a first hinge hole, a second hinge hole and a third hinge hole; the third hinge hole is hinged with a chassis of a tank-transport truck; one end of the main oil cylinder is hinged with the second hinge hole, and the other end of the main oil cylinder is hinged with the chassis of the tank-transport truck; and one end of the supporting connecting rod is hinged with the first hinge hole, and the other end of the supporting connecting rod is hinged with the lifting mechanism. Since the structure of the landing gear and the supporting connecting rod is adopted, a connecting rod mechanism is formed between the landing gear as well as the supporting connecting rod and the main oil cylinder as well as the lifting mechanism, and thrust force of the main oil cylinder is uniformly acted on a lifting arm; and thus, the lifting arm is slowly and stably opened or folded, and the defect of large shock produced by the lifting arm during releasing of an auxiliary oil cylinder and acting of the main oil cylinder existing in the prior art is avoided.

Description

technical field [0001] The invention relates to an automatic loading and unloading device, in particular to an automatic loading and unloading device for vehicles. In addition, the present invention also relates to an automatic loading and unloading vehicle equipped with the automatic loading and unloading device. Background technique [0002] At present, most of the construction mortar used in my country's construction industry uses a bulk mobile silo storage device, which is used together with a continuous mixer and often operates between the construction site and the dry mixing station. In the traditional mode of operation, the joint operation of lifting equipment and transport vehicles is often used to carry the mobile silo, which causes various wastes of financial resources, manpower, material resources and time.

AI Technical Summary

Problems solved by technology

In the traditional mode of operation, the joint operation of lifting equipment and transport vehicles is often used to carry the mobile silo, which causes various wastes of financial resources, manpower, material resources and time. There are also problems in the following aspects:

[0003] 1) In the lifting stage, the combination of the auxiliary cylinder and the main cylinder is used to add a control method, and when the auxiliary cylinder is disengaged, the lifting arm is prone to vibration to a certain extent, which poses a safety hazard

[0004] 2) The main oil cylinder is directly connected to the lifting arm, which requires high synchronization of the two main oil cylinders, and it is difficult to achieve precise control
