Self-unloading carriage applied to trailer

Abstract

The invention discloses a self-unloading carriage applied to a trailer, relates to the technical field of plastic processing, and solves the problem that the joint of a tractor and a trailer is difficult to move. A self-unloading carriage applied to a trailer comprises a trailer frame, a traction table is arranged at one end of the trailer frame, hydraulic supporting rods are movably connected to the two sides of the trailer frame, a supporting structure is fixedly installed at the lower end of the traction table, and a rotating structure is movably connected to the upper end of the supporting structure; the upper end of the rotating structure is movably connected with a connecting structure, an inserting structure is fixedly installed on the upper surface of the connecting structure, the supporting structure comprises two sets of fixing bottom feet, a movable base, a containing inner groove, a fixing hole groove and a movable bearing, and each set of fixing bottom feet comprises two fixing bottom feet. By means of the self-unloading carriage applied to the trailer, the multi-angle moving function of the trailer and a tractor during vehicle moving can be achieved.

Description

technical field [0001] The invention relates to the technical field of trailer traction, in particular to a self-unloading compartment applied to a trailer. Background technique [0002] A semi-trailer tractor is a commercial vehicle equipped with special devices for towing a semi-trailer. There are two ways to connect the tractor and the trailer: the first is that the front half of the trailer is placed on the traction saddle above the rear section of the tractor. The bridge behind the tractor bears part of the weight of the trailer, which is a semi-trailer. [0003] However, the existing connecting parts of the trailer and the tractor have a single structure, and it is difficult to realize the angle buffering between the trailer and the tractor. For example, when the tractor enters the ramp, an angle will be generated between the tractor and the trailer. The connection condition is extremely unstable, and it does not have the function of multi-angle activities; therefore,...

AI Technical Summary

Problems solved by technology

[0004] The object of the present invention is to provide a self-unloading carriage applied to a trailer to solve the connection between the trailer and the tractor proposed in the above-mentioned background technology. The structure is relatively simple and it is difficult to realize the angle buffer between the trailer and the tractor. When entering the ramp, there will be an angle between the tractor and the trailer. At this time, the connection condition of the connecting part is extremely unstable, and it does not have the function of moving at various angles.
