Problems solved by technology

[0004] In order to make up for the deficiencies of the existing technology, the length of the longitudinal beam assembly of the semi-trailer on the market is fixed. When the length of the longitudinal beam assembly is greater than the length of the container, the position of the container will be difficult to fix; When the formed length is less than the length of the container, the container is easy to fall off from the vehicle, causing safety accidents; the invention proposes a semi-trailer longitudinal beam assembly

Embodiment approach

[0023] As an embodiment of the present invention, a No. 2 chute 22 is opened on the side wall of the top column 2; a slider 221 is slidably connected in the No. 2 chute 22; the slider 221 and the locking plate 51 A connecting rod 512 is arranged between, one end of the connecting rod 512 is hinged on the slider 221, the other end of the connecting rod 512 is hinged on the bayonet plate 51, and the connecting rod 512 is provided with a support rod 513, so that the support rod 513 and the sleeve 3 side wall contact; strengthen the strength and reliability of the locking unit 5 through the cooperation of the slider 221 and the connecting rod 512; during operation, when the length of the longitudinal beam assembly needs to be adjusted according to the container of different length, the air pump is controlled by the controller Supply air to the cylinder 4, so that the cylinder 4 expands and contracts, thereby pushing the top column 2 to slide in the sleeve 3. During the expansion an...

Abstract

The invention belongs to the technical field of semi-trailers, in particular to a semi-trailer longitudinal beam assembly. The semi-trailer longitudinal beam assembly comprises a beam frame, a top column, a sleeve, an air cylinder and a clamping unit; the side wall of the top column is provide with a first clamping tooth; the sleeve sleeves on the outer side of the top column, and a first slidinggroove is formed in the position, close to the first clamping tooth, of the sleeve; the air cylinder is fixedly arranged on the side wall of the sleeve; the clamping unit comprises a clamping tooth plate and a piston cylinder; the clamping tooth plate is slidably connected in the sliding groove, and the clamping tooth plate is provided with a second clamping tooth near the first clamping tooth; the piston cylinder is installed in first sliding groove, and the longitudinal beam assembly is lengthened and shortened through the cooperation of the beam frame, the top column, the sleeve, the cylinder and the clamping unit, so as to strengthen the fixing effect on the container in the transportation process, thus realizing the change of the length of the longitudinal beam assembly, greatly improving the use range and the use effect of the semi-trailer longitudinal beam assembly, increasing the practicability of the longitudinal beam assembly and bringing great convenience to users.

Description

technical field [0001] The invention belongs to the technical field of semi-trailers, in particular to a longitudinal beam assembly of a semi-trailer. Background technique [0002] At present, the lightweight of automobiles has become the consensus of the automobile industry. At present, most semi-trailers are mostly welded by steel structural parts, which have problems such as large welding volume, high fuel consumption, and heavy vehicle weight. In the case of meeting the use requirements, the weight of the semi-trailer should be fully reduced, in response to the call for energy conservation and emission reduction, to save fuel costs for users and improve operating profits, so the proportion of aluminum alloy materials used in the vehicle structure is gradually increasing; The beam is the main load-bearing part of the semi-trailer, and its strength affects the performance of the entire vehicle. In the case of meeting the requirements of the regulations, the weight reducti...
