An easy unloading container semi-trailer

Abstract

The invention relates to the field of semi-trailers, in particular to a container semi-trailer facilitating cargo unloading. The container semi-trailer comprises a trailer frame, a container body, container pushing devices, container conveying devices, frame feeding devices and air bags. Each container pushing device comprises a container jacking hydraulic rod, a forward pushing device and a backward feeding device. Each container conveying device comprises a forward conveying device and a backward conveying device, and the forward conveying device further comprises a forward conveying motor and a motor frame. Each frame feeding device comprises a rotary plate, a connecting shaft, a supporting frame, a frame feeding motor, a first sliding rod, a second sliding rod, a connecting rod and a limiting plate. A container can be automatically and horizontally moved away from the semi-trailer and can be automatically conveyed to a specified container placement area; and the container can be automatically placed on the ground, manpower is saved, inclination of the container and shaking of the semi-trailer are avoided, and a semi-trailer body and cargos in the container are effectively protected.

Description

Technical field [0001] The invention relates to the field of semi-trailers, in particular to an easy-discharge container semi-trailer. Background technique [0002] Semi-trailers are commonly used in our lives, and they also bring us a lot of convenience. Container transport semi-trailers are a special kind of goods that have a large variety of different shapes and sizes into standard sizes before transportation The inside of the box is convenient for water, land and air transportation. 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. [0003] In the prior art, the method for unloading containers by semi-trailers often uses hydraulic lifting devices. The side of the container close to the cab i...

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
