Ceiling and side curtain cloth semitrailer

Abstract

The invention relates to a ceiling and a side curtain cloth semitrailer. The ceiling comprises two parallel guide rails (1), supports (2), tarpaulin and a locking assembly (4), rails are arranged on the upper side and the lower side of each guide rail (1), each support (2) comprises a supporting rod (21) and a telescopic structure (22), and the supporting rods (21) are perpendicular to the guide rails (1). The two ends of each telescopic structure (22) are slidably supported on rails on the upper sides of the two guide rails (1), the supporting rods (21) are arranged at intervals in the guiding direction of the guide rails (1), the telescopic structures (22) are located between the adjacent supporting rods (21), the ends of the telescopic structures (22) are fixedly connected with the supporting rods (21), and the telescopic structures (22) are of an integrated structure and the middle part of the telescopic structures (22) is a curved face bending downward. A bent part is arranged inthe middle of the telescopic structure in the ceiling. Therefore, bending is convenient, a driving assembly is not needed, and opening and closing of the ceiling can be completed only through manpower.

Description

technical field [0001] The invention relates to the technical field of special vehicles, in particular to a roof and side curtain semi-trailer. Background technique [0002] At present, traditional warehouse vehicles need to be covered with tarpaulins during operation, especially for semi-trailers with a height of 13m, which not only requires the cooperation of several people, but also needs to be covered with tarpaulins on the roof, which is time-consuming and laborious and poses a great safety hazard. There is a lot of criticism in the transportation industry. Therefore, there is an urgent need for a roof system to solve this problem. [0003] Patent CN205737171U discloses a roof automatic retractable mechanism, in which a chain transmission system is used to realize the opening and closing of the telescopic ceiling. It can be seen that the retractable ceiling in this patent cannot be opened and closed by manpower due to design reasons, and this will cause great disadvan...

AI Technical Summary

Problems solved by technology

It can be seen that the retractable ceiling in this patent cannot be opened and closed by manpower due to design reasons, and this will cause great disadvantages

First of all, the design of the chain drive system is more difficult, which will increase the cost of the vehicle and increase the difficulty of the design of the vehicle master control system.

Secondly, the chain drive system is bulky and will occupy limited space on the roof, which will also increase the weight of the roof and increase the burden on the uprights on the frame.
