Description

Technical Field

[0001] This invention belongs to the technical field of railway vehicle maintenance and production equipment, specifically a three-dimensional wheelset selection warehouse with a chain conveyor at the bottom of the storage area. Background Technology

[0002] Currently, the wheelset selection and matching systems in most depots across the railway network suffer from space constraints, resulting in insufficient buffering of the four-wheelset queues after selection, severely impacting production efficiency. For example, at the start of the workday, the outbound gantry robots are idle, while in the afternoon, they are too slow to operate. Furthermore, the automated warehouse exit 1B is often located at one end of the wheelset selection and matching warehouse 1, making it difficult to operate even with two gantry robots. Its main drawback is low wheelset outbound efficiency. Summary of the Invention

[0003] In view of the problems existing in the prior art, the purpose of the present invention is to provide a three-dimensional wheelset selection library with a chain conveyor at the bottom of the storage area, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: The railway vehicle depot or vehicle factory includes a three-dimensional wheelset selection warehouse 1. The three-dimensional wheelset selection warehouse 1 includes a warehouse entrance 1A, an upper selection area 1D, wheelsets 2, a chain conveyor 3, a steel structure 6, and a gantry robot 7. The steel structure 6 includes a support 6A and a gantry 6C. The chain conveyor 3, located below the gantry 6C, includes a conveyor entrance 3A. Wheelets 2 can be stored and operated on the chain conveyor 3. The support 6A is located above the gantry 6C. Wheelets 2 in the upper selection area 1D above the gantry 6C are horizontally staggered and placed on the support 6A. The gantry robot 7 picks up wheelsets 2 from the warehouse entrance 1A and places them on the support 6A. The gantry robot 7 can pick up the selected wheelsets 2 and place them at the conveyor entrance 3A, and then transport them to a designated position via the chain conveyor 3.

[0005] As a further embodiment of the present invention: the wheelset 2 includes a wheel rim 2A, the chain conveyor 3 includes an accumulation chain 4 and an accumulation chain track 5, the accumulation chain 4 includes a support roller 4A, a traveling wheel 4B and a chain piece 4C, the traveling wheel 4B is located on both sides of the support roller 4A, the support roller 4A includes a rim-supported support roller 4A1 and a smooth wheel 4A2, the diameters of the rim-supported support roller 4A1 and the smooth wheel 4A2 are equal, the rim-supported support roller 4A1 includes a support roller rim 4A1A, the support roller 4A supports the wheel rim 2A, and the traveling wheel 4B travels on the accumulation chain track 5.

[0006] As a further aspect of the present invention: the gantry robot 7 includes a large vehicle 7A, a small vehicle 7B, a lifting device 7C, and a gripper 7D that can move longitudinally. The small vehicle 7B can move laterally on the large vehicle 7A. The gripper 7D that can grasp the wheel pair 2 is installed on the lifting device 7C, and the lifting device 7C is installed on the small vehicle 7B.

[0007] As a further aspect of the present invention: the chain conveyor 3 includes a conveyor outlet 3B, through which a group of four wheelsets 2 are transported to a set position on the bogie line after selection.

[0008] As a further aspect of the present invention: the conveyor inlet 3A includes an opening 3A1 located in the middle of the upper selection area 1D.

[0009] As a further aspect of the present invention: the wheelset three-dimensional matching warehouse 1 includes a three-dimensional warehouse exit 1B, and the gantry robot 7 can grab the selected low-position wheelset 2B or high-position wheelset 2C and place them in the three-dimensional warehouse exit 1B.

[0010] As a further aspect of the present invention: the bracket 6A includes a low bracket 6A1 and a high bracket 6A2, and the wheelset 2 in the upper selection area 1D includes a low wheelet 2B and a high wheelet 2C that are horizontally staggered and vertically staggered. The low wheelet 2B rests on the low bracket 6A1, and the high wheelet 2C rests on the high bracket 6A2.

[0011] In summary, compared with the prior art, the present invention, by setting up a lower buffer area, allows the gantry robot to pre-queue and cache the wheelsets that have been selected in groups of four on the accumulation chain as soon as it starts working. When there are two gantry robots, the conveyor entrance is arranged in the middle of the upper selection area, so there is no interference between them. Its main advantages are: high wheelset outbound efficiency and small footprint. Attached Figure Description
