Universal box body of van with liftable ceiling

Abstract

A universal box body of a van with a liftable ceiling comprises a bottom frame, a lower box body, an upper box body, a lifting driving mechanism and a carriage ceiling curtain pulling mechanism, the bottom frame is a steel structure rectangular frame, and four detachable supporting legs are installed on the lower portion of the bottom frame; the lower box body comprises four steel structure main stand columns and four steel structure side stand columns. The upper box body comprises a box top side reinforcing frame, four upper box body top stand columns and a box top front corrugated board. The upper box body is connected with the lower box body through a moving pair, a logistics worker controls the lifting driving mechanism through manpower, then the upper box body ascends and descends relative to the lower box body, and the transfer requirements of van trucks of different specifications are met by changing the rated volume of the box body. The compartment ceiling curtain pulling mechanism comprises an aluminum alloy rail, a waterproof piece, a compartment top curtain pulling front fixing cross beam, a ceiling cross rod bearing frame and a ceiling cross rod, a compartment top curtain pulling is flexibly folded and opened on the aluminum alloy rail through the ceiling cross rod, and hoisting, loading and unloading of heavy objects are facilitated.

Description

technical field [0001] The invention relates to the field of carriages, in particular to a universal box body of a van truck with a liftable ceiling. Background technique [0002] The box body is an important part of the truck and the key structure of the van for cargo transportation. It is widely used in logistics express, supermarkets, major factories and other occasions. The box body of a van is mostly composed of a bottom plate, left and right side panels, a front panel, a rear panel, and a top panel that are welded or hinged to each other. Common van models include box-type mini-cars, van-type medium-sized cars and container-type large Although vans are widely used, there are many problems in the actual application process. [0003] On the one hand, vans of different specifications carry different sizes of boxes. In actual freight transportation, since the volume of the box cannot be changed, vans of different specifications must be reloaded and unloaded to realize the...

AI Technical Summary

Problems solved by technology

Due to the inability of large, medium and small vans to achieve fast transshipment, resulting in low logistics efficiency and high labor costs, logistics companies have to bear greater transport pressure during the peak period of online shopping

On the other hand, the ceiling of the van box body is generally fixed and cannot be opened, which satisfies the hoisting requirements of large and heavy parts.
