Refrigerated van type transportation semitrailer

Abstract

The invention belongs to the field of automobiles special for cold chain transportation, and relates to a refrigerated van type transportation semitrailer, including a box body assembly, a walking mechanism assembly arranged on the box body assembly, a refrigerating unit arranged on the box body assembly, traction device arranged on the box body, a supporting device assembly arranged at the bottomof the box body, and an oil tank assembly and a tool box assembly arranged in the supporting device assembly, a guardrail assembly arranged on the outer side of the oil tank assembly, a fender assembly arranged on the outer edge of the walking mechanism assembly, and a rear bumper assembly arranged on the side face of the bottom of the box body. For the refrigerated van type transportation semitrailer, specific section design is carried out on the box body assembly and the frame assembly, and machining, bending and other machining procedures are carried out through aluminum extrusion, and theuse requirements of all components are met. And the use amount of steel is reduced in the whole vehicle, so that the whole vehicle is corrosion-resistant, light in weight, good in environmental protection benefit, high in recovery value and high in box body strength, foaming materials are prepared on site, and the residual rate is controllable.

Description

technical field [0001] The invention belongs to the field of special vehicles for cold chain transportation, and relates to a refrigerated box type transportation semi-trailer. Background technique [0002] Refrigerated trucks are special vehicles for cold chain logistics, used to transport perishable goods and goods with specific temperature requirements. Refrigerated trucks are important road refrigerated transportation tools. Its basic function is to keep the goods from rot and deterioration during the entire transportation process under any external environmental conditions (mainly temperature conditions). Refrigerated trucks are divided into refrigerated bicycles and refrigerated semi-trailers according to the models in the existing market. Refrigerated bicycles are mainly composed of a second-class chassis, refrigerated box, refrigerator (excluding diesel engine), etc. Refrigerated semi-trailers are mainly composed of refrigerated box, semi-trailer Trailer traveling ...

AI Technical Summary

Problems solved by technology

Due to the complex structure, high cost and high production cost of the box board, enterprises rarely use it, but this kind of structural box has good environmental protection benefits, high recycling value, high box strength, especially the high utilization rate of aluminum alloy, which is easy to recycle, and foam material On-site preparation remaining rate is controllable
