Problems solved by technology
[0003] However, as far as the current traditional air suspension semi-trailer is concerned, first of all, the existing device cannot realize buffering when the cover plate is closed, which reduces the service life of the cover plate, and the noise is relatively large when it is closed; secondly, the existing device is in the cover. After the board is opened, it cannot be automatically positioned

Embodiment
[0036] Example: Please refer to Figure 1 to Figure 8 :
[0037] The present invention proposes an air suspension semi-trailer with side wings open tarpaulin, including: a compartment 1, an adjustment part 2 and an auxiliary part 3;
[0038] Compartment 1 is installed on the vehicle frame;
[0039] There are two adjustment parts 2, and the adjustment part 2 is composed of a rotating seat 201, a rotating shaft 202, a cover plate 203, a gear 204, a drive motor 205, an adjustment rod 206, a tarpaulin 207, an auxiliary frame 208 and a locking block 209; There are two seats 201, and the two rotating seats 201 are fixedly connected to the carriage 1 by bolts;
[0040] There are four auxiliary parts 3 in total, and the auxiliary parts 3 are composed of a sliding seat 301 , a sliding rod 302 and an elastic member 303 .
[0041] In addition, according to an embodiment of the present invention, as Figure 4 As shown, two fixing plates 101 are welded on the compartment 1, and the two...

The invention provides an air suspension semitrailer with side wing opening tarpaulin, which relates to the technical field of semitrailers and comprises a carriage, an adjusting part and an auxiliary part, the carriage is mounted on the frame; two fixing plates are welded to the carriage, and the two fixing plates are each of a rectangular plate-shaped structure. Due to the fact that the sliding rod is aligned with the fixing bolt in position, the head end of the sliding rod makes contact with the top end face of the fixing bolt under extrusion of the locking block after the cover plate is closed, the sliding rod forms a looseness detection structure of the fixing bolt, in other words, when the fixing bolt is loosened, the cover plate cannot be closed, and the problem that the cover plate cannot be closed is solved. According to an existing device, buffering cannot be achieved when a cover plate is closed, the service life of the cover plate is shortened, and noise is large when the cover plate is closed. And secondly, the problem that an existing device cannot be automatically positioned after a cover plate is opened is solved.
Description
technical field [0001] The invention relates to the technical field of semi-trailers, in particular to an air-suspended semi-trailer with side wings and an open tarpaulin. Background technique [0002] According to the implementation requirements of the current road traffic on the rigid policy of overrunning and overloading, the lightweight of semi-trailers has become an inevitable trend in its future development, and with the rapid development of the network e-commerce market, logistics companies are spread all over the country, and express delivery companies have developed to In all corners of the country, the road transportation industry has been greatly developed, making the application range of van semi-trailers wider and wider. [0003] However, as far as the current traditional air suspension semi-trailer is concerned, first of all, the existing device cannot realize buffering when the cover plate is closed, which reduces the service life of the cover plate, and the n...
