System and method for jointly assembling axles and chassis of semi-trailers

Abstract

The invention discloses a system and a method for jointly assembling axles and chassis of semi-trailers. The system comprises a chassis conveying mechanism, axle conveying mechanisms and a lifting mechanism. The chassis conveying mechanism comprises a front-end roller bed, a rear-end roller bed and two pallets, the front-end roller bed and the rear-end roller bed are parallel to each other, two roller bed supports are fixedly arranged at the lower end of each of the front-end roller bed and the rear-end roller bed, rollers are arranged on the front-end roller bed and the rear-end roller bed, and the two pallets can be supported at the front end and the rear end of the chassis of each semi-trailer and are slidably arranged on the rollers; each axle conveying mechanism comprises a transport component, the transport components are arranged below the front-end roller bed and are slidably arranged on tracks on the ground, and two bearing seats are arranged on the side, which is close to the corresponding roller bed supports, of each transport component; the lifting mechanism comprises a hydraulic lifting machine arranged in the ground at the front of the rear-end roller bed, axle supporting seats are arranged on the hydraulic lifting machine, and the hydraulic lifting machine is positioned in central regions of two opposite sides of the ground in the width directions. The system and the method have the advantages that deformation of frames in operation procedures can be prevented, valueless operation proportions can be reduced, the working procedure operation time can be shortened, and the problems of potential safety hazards and the like during hoisting operation can be solved.

Description

technical field [0001] The invention relates to the technical field of semi-trailers, in particular to a combined assembly system and method for an axle and a chassis of a semi-trailer. 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 li...
