Description

Technical Field

[0001] The present application relates to the technical field of truck longitudinal beam transfer, and in particular to a longitudinal beam auxiliary transport structure and device. Background Art

[0002] At present, the length of truck frame longitudinal beams is generally 4-12 meters and the weight is 100-200kg. Under specific working conditions in the factory workshop, for example, when transferring the frame longitudinal beams to the C-shaped cavity of the flip mechanism, the traditional truss manipulator is limited by space and other factors and cannot directly transfer the frame longitudinal beams of different lengths into the C-shaped cavity.

[0003] At present, the main goal is to achieve fully automated transportation of the frame longitudinal beams throughout the entire cycle; however, due to the space limitations of the factory workshop, the process of transporting the frame longitudinal beams to the flip structure currently relies mainly on manual operation; there are several reasons: First, when the frame longitudinal beams are automatically transported to the vicinity of the flip structure through the roller structure on the production line, the frame longitudinal beams are then transported to the flip structure using a truss manipulator, but due to the space limitations of the automated production line, there is physical interference between the truss manipulator and the flip structure in the limited space, and multiple people are required to lift both sides of the frame longitudinal beams, which is extremely laborious and time-consuming, and there are certain safety risks; second, an intelligent overhead crane is used; however, the disadvantage of an intelligent overhead crane is that it is expensive and requires manual assistance, and cannot achieve unmanned operation of a fully automated assembly line. Secondly, the accuracy of the intelligent overhead crane cannot meet the use requirements, so it cannot be applied to automated production lines.
