AI Technical Summary
In the wheel and axle workshops of railway vehicle factories or depots, the loading and unloading time of wheelsets at the bearing break-in machine station is too long, resulting in high labor intensity for workers and low production efficiency.
The system employs a gantry robot and a conveyor system. The conveyor system transports wheelsets between the placement position, the working position, and the picking position. Combined with a lifting device, the height of the wheelsets is adjusted. The gantry robot's large and small carriages move longitudinally and laterally within the factory building, achieving efficient wheelset transport.
This significantly shortens the loading and unloading time of wheelsets at the bearing break-in machine station, reduces the labor intensity of operators, and improves production efficiency.

When the front stopper 5C retracts, the wheelset 1A that has completed its work on the working position 3B rolls to the retrieval position 3C.
[0006] As a further embodiment of this utility model: the conveyor 4 includes a lifting device 7 located on the working position 3B, which lifts and adjusts the height of the wheelset 1A to complete the positioning of the wheelset 1A on the bearing break-in machine 3.
[0007] As a further embodiment of this utility model: the gantry robot 2 includes a large trolley 2A, a small trolley 2B, a lifting device 2C, and a gripper 2D. The large trolley 2A includes a transverse track 2AY. The gripper 2D that grasps the wheel pair 1A is mounted on the lifting device 2C, and the lifting device 2C is mounted on the small trolley 2B. The small trolley 2B moves laterally on the transverse track 2AY, and the large trolley 2A moves longitudinally within the factory building.
[0008] In summary, compared with the prior art, the main advantages of this utility model are: by using a gantry robot and a conveyor, this utility model greatly shortens the loading and unloading time of wheelsets at the bearing break-in machine station, reduces the labor intensity of operators, and improves production efficiency.
