A new type of container semi-trailer

Abstract

The invention relates to the field of semitrailers, in particular to a novel container type semitrailer. The novel container type semitrailer comprises a car frame, a box body, a box push device, a box transport device and a frame transport device, wherein the box push device comprises a top box hydraulic rod, a forward push device and a backward conveying device; the box transport device comprises a forward transport device and a backward transport device, and the forward transport device comprises a main conveying frame, a rotating shaft, a rotating stand, a rotating hydraulic rod, a wheel-connection hydraulic rod, a wheel stand, a spring and a box transport wheel, and the backward conveying device comprises a main conveying frame, a rotating shaft, a rotating stand, a rotating hydraulic rod, a wheel-connection hydraulic rod, a wheel stand, a spring and a box transport wheel too; the frame conveying device comprises a rotary disc, a connection shaft, a support frame, a frame transport motor, a first slide bar, a second slide bar, a connection rod and a location-limited plate. The novel container type semitrailer can enable a container to automatically and horizontally to leave a semitrailer, and can enable the container to be automatically transported to an appointed placement area of containers without the need of manual operation, slant of the container and shake of the semitrailer cannot be caused, thus the semitrailer body and goods in the container are effectively protected.

Description

technical field [0001] The invention relates to the field of semi-trailers, in particular to a novel container-type semi-trailer. 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 a container; the vehicle specially used to transport containers is a container transport semi-trailer.

AI Technical Summary

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
