Self-dumping truck large-cargo compartment backdoor anti-swing jump-stopping device

Abstract

The invention provides a self-dumping truck large-cargo compartment backdoor anti-swing jump-stopping device. The self-dumping truck large-cargo compartment backdoor anti-swing jump-stopping device comprises a cargo carrying box; two sides of the upper part of a cargo compartment backdoor are connected to the upper part of the box tail of the cargo carrying box in a hinged mode, and lock catches are in welded connection with the lower end of the cargo compartment backdoor; another lock catches are installed on a box tail bottom plate of the cargo carrying box, and the two groups of lock catches are uniformly distributed at the tail end of the bottom plate of the cargo carrying box; supporting plates are in welded connection with the two side surfaces of the cargo compartment backdoor, andlimiting clamping hooks are in welded connection with the right sides of the supporting plates; hinged pieces are in welded connection with the supporting plates, and one ends of spring plates are connected to the hinged pieces; limiting protruding blocks are in welded connection with the outer side surfaces of the spring plates; and wedge-shaped baffles are in welded connection with the two sidesurfaces of the cargo carrying box. It is observed that compared with an existing truck self-dumping box, the spring plates and the wedge-shaped baffles are additionally arranged to fix positions of abox door and a box body when the box door collides with the box body at the first time, secondary collision is avoided, and the service life of the truck box body is prolonged.

Description

technical field [0001] The invention belongs to the field of a large compartment of a dump truck, and more specifically relates to an anti-swing and anti-jump device for a rear door of a large compartment of a dump truck. Background technique [0002] In modern transportation work, means of transportation play a very important role. Having a truck with automatic unloading function will make the unloading work easier, improve work efficiency and save manpower and material resources. On the common car body with self-unloading function The rear door of the truck body often swings after unloading, and sometimes the swing violently hits the body of the truck body, making noise, and the accumulated collisions will gradually deform the truck body. Unnecessary collisions will reduce the service life of the truck body. [0003] For example, the existing Chinese invention patent with the patent number CN201220018364.9 discloses an automatic leak-connecting device for materials transpo...
