Side wing opening tarpaulin type air suspension semitrailer

Abstract

The invention provides a side wing opening tarpaulin type air suspension semitrailer, relates to the technical field of semitrailer machinery, and aims to solve the problems that a side box plate is difficult to open, the use is very inconvenient, and the tarpaulin needs to be detached because most of the tarpaulin of the existing semitrailer is of a traction structure. The side wing opening tarpaulin type air suspension semitrailer comprises a semitrailer body; side wing plates are fixedly mounted at the edges of the left end and the right end of the top plate body of the semitrailer body in a vertically upward manner; detachable structures are arranged between the side wing plates and the semitrailer body; the tarpaulin is of an inverted-U-shaped structure and is longitudinally installed between the upper ends of the left side wing plate and the right side wing plate in a sliding mode. As the third roll shaft is transversely and rotationally mounted in the middle of the front end of the clamping plate, the height of the third roll shaft tends to the middle of the first roll shaft and the fourth roll shaft, and the extension frame can be slidably clamped to the telescopic base frame through the clamping plate, front-back stretching and retracting are facilitated, tarpaulin can be conveniently stored and folded, and the movable box plate can be conveniently opened for use; meanwhile, the extension frame can be prevented from being broken when not in use.

Description

technical field [0001] The invention relates to the technical field of semi-trailer machinery, and more specifically relates to a side-opening cloth type air-suspension semi-trailer. Background technique [0002] At present, the road traffic requires the implementation of the rigid policy of overloading, and the lightweight of the semi-trailer has become an inevitable trend in its future development. In order to ensure the cleanliness of the road, tarpaulins are usually used to cover it to prevent sandy goods from falling. [0003] For example, in the patent application CN202020591964.9, a side-opening-cloth air suspension semi-trailer belongs to the technical field of side-wing air-suspension semi-trailer; the technical problem to be solved is: to provide a side-opening air suspension The improvement of the structure of the semi-trailer; the technical solution adopted to solve this technical problem is: including a semi-trailer compartment and a vehicle frame, the semi-trai...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the above technical problems, the present invention provides a side-opening tarpaulin-type air suspension semi-trailer to solve the problem that the tarpaulins of the current semi-trailers are mostly pull-type structures, which require manual pulling, and the manual pulling method is easy to get stuck. It is extremely inconvenient to operate, and the pulling track is preset and fixed, which makes it difficult to open the side box panel. It is extremely inconvenient to use, and the tarpaulin needs to be disassembled
