A semi-trailer container automatic running mechanism

Abstract

The invention relates to the field of semitrailers, in particular to an automatic walking mechanism of a semitrailer container. The automatic walking mechanism comprises a frame, a container body, a container conveying device and a frame conveying device. The container conveying device and the frame conveying device are located behind the frame. The container body is the body for the container. The container conveying device comprises a forward conveying device and a backward conveying device. The forward conveying device and the backward conveying device each comprise a main conveying frame, a rotating shaft, a rotating frame, a rotating hydraulic rod, a connecting wheel hydraulic rod, a wheel frame, a spring and a container conveying wheel. The forward conveying device further comprises a forward conveying motor and a motor frame. The frame conveying device comprises a rotating disc, a connecting shaft, a supporting frame, a frame conveying motor, a first sliding rod, a second sliding rod, a connecting rod and a limiting plate. Automatic conveying of the container can be achieved, the container get away from the semitrailer horizontally and moved to the designated container placement region, no manual operation is needed, and the semitrailer body and cargos inside the container are effectively protected.

Description

technical field [0001] The invention relates to the field of semi-trailers, in particular to a semi-trailer container automatic running mechanism. Background technique [0002] Semi-trailers are widely used in our lives, and they also bring us a lot of convenience. Container transport semi-trailers are a special type of container that loads goods of various shapes and sizes into standard sizes before transportation. The box is convenient for water, land and air transport. It can realize loading and unloading, transportation mechanization and standardization. It is a major reform of traditional transportation methods and an important part of transportation modernization. This kind of special box is the container; the vehicle specially used to transport the container is the container transport semi-trailer.

Problems solved by technology

[0003] However, in the prior art, the semi-trailer often uses a hydraulic lifting device to unload the container. The side of the container near the driver's cab is lifted through the hydraulic jack, and then the hydraulic rod is stretched out to lift the container. The container is slowly placed on the ground from the rear of the semi-trailer; during the whole process, the container is in a tilted state, and when the container moves to the rear of the vehicle body, the chassis of the vehicle body is easy to shake, which in turn easily damages the items in the container, and It is easy to cause wear and tear on the semi-trailer; thus, it is urgent to improve the traditional semi-trailer unloading method
