Description

Technical Field

[0001] The present application relates to the technical field of commercial vehicle assembly, and particularly relates to a gantry beam subassembly transfer station device. Background Art

[0002] At present, before the gantry beam of a commercial vehicle is assembled onto the vehicle frame, it generally needs to be subassembled, stored, and transferred. Since the gantry beam parts are relatively large, appropriate multi-functional station devices are required for subassembly. After subassembly, the assembled gantry beam units cannot be stacked to avoid damage caused by collision of parts. After subassembly is completed, the assembled gantry beam units need to be transferred from the subassembly area to the general assembly production line for assembly.

[0003] In related technologies, traditional gantry beam station devices are only suitable for storing scattered parts of the gantry beam. After the scattered parts are assembled into assembled gantry beam units, the assembled gantry beam units need to be temporarily stored in other positions outside the gantry beam station device. After all the scattered parts in the gantry beam station device are assembled into assembled gantry beam units, all the assembled gantry beam units are then transported to the gantry beam station device for transfer. This increases the operation steps and operation time, and the surfaces of the parts are easily damaged by collision, resulting in low subassembly operation efficiency.

[0004] Therefore, it is necessary to design a new gantry beam subassembly transfer station device to overcome the above problems. Summary of the Utility Model
