Embodiment Construction
[0032] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0033] In this embodiment, the device proposed by the present invention for the assembly of semi-trailer axles and chassis includes: a ground track for transporting the vehicle axle 7, and a vehicle axle transport trolley 1 running on the ground track. The bridge roller table 2 supporting the front and rear ends of the semi-trailer chassis 6 and the hydraulic lift 4 used to lift the axle 7, the upper end of the track section of the ground track is basically flush with the ground, and the axle conveying trolley 1 is driven by a battery The motor drives the wheels of the axle conveying trolley 1 to walk on the ground track. The frame of the axle conveying trolley 1 is a U-shaped structure, and the axle conveying trolley 1 is movable along the moving direction. The distance between the V-shaped seats of the adjacent axles can be adjusted according ...

The invention relates to a device and method for assembling an axle and a chassis of a semitrailer. The device comprises a ground track used for conveying the axle, an axle conveying trolley traveling on the ground track, two bridge-type roller ways used for supporting the front end and the rear end of the chassis of the semitrailer correspondingly, and a hydraulic lifter used for lifting the axle. A trolley frame of the axle conveying trolley is of a U-shaped structure. The U-shaped structure of the axle conveying trolley is at least movably provided with a V-shaped axle bearing seat in the moving direction. The V-shaped axle bearing seat comprises a left seat body and a right seat body which are arranged in parallel symmetrically. The hydraulic lifter is installed and fixed to the ground. According to the device and method for assembling the axle and the chassis of the semitrailer, the chassis of the semitrailer does not need to be turned over, the trolley frame is prevented from deforming, and the ratio of worthless operation is lowered; the assembling procedure needs only one station, and the occupied space is reduced; multiple axles are assembled simultaneously, so that the operation time of the procedure is substantially shortened; and as no lifting equipment is used, operation is safer, easier and more convenient.
Description
technical field [0001] The invention relates to the technical field of semi-trailer assembly, in particular to a device and method for assembling a semi-trailer axle and chassis. Background technique [0002] A semi-trailer is usually composed of a body loaded with goods, a chassis that carries the body and is connected to the tractor, a walking system composed of an axle and a suspension, and other systems. Conventional products are divided into single-axle, double-axle parallel, and three-axle parallel-mounted, etc. different styles. The assembly and manufacture of the semi-trailer is usually after the above systems are assembled into a whole, and then assembled into a semi-trailer. Among them, the joint assembly of the semi-trailer axle and chassis is one of the key processes in the entire assembly process. The traditional method in the semi-trailer manufacturing industry is to turn the chassis over and place it on the assembly station, and use cranes and other lifting e...
