[0002] A transfer vehicle is a vehicle used to transport goods or personnel between different places. In a factory, it is often necessary to transfer goods between different locations. To facilitate the transfer, a special track will be set up to facilitate the movement of the transfer vehicle. At present, the conveying structure of the mobile conveying equipment mainly adopts rubber-coated wheels for bearing, and the conveying track adopts rectangular steel pipes and is assisted by guide wheels. The weight of the workpiece that can be carried by the rubber-coated structure is small, and it cannot handle heavy workpieces. In addition, the rubber-coated wheels have certain requirements for the working environment. Using them in areas with high or low temperatures will have a greater impact on the life of the rubber-coated wheels. The guide structure and guide wheels of the equipment need to be adjusted on site, and there are certain requirements for the quality of the construction and installation personnel. The equipment originally adopted the form of rubber-coated rollers, but because the equipment needs to be transported in the X direction, it is often not easy to intuitively see whether the rubber-coated rollers are accurately docked during docking, and the life of the rubber-coated rollers will be greatly affected when facing heavy loads.
