Description

Technical Field

[0001] This invention belongs to the field of railway vehicle maintenance equipment technology, specifically a disassembly and maintenance system for components in freight car frame maintenance lines. Background Technology

[0002] Currently, the disassembly, repair, assembly, and parts storage of components (such as crossbars, wedges, and wear plates) in various depots across the railway system still adhere to the traditional concept of each unit being independent. In particular, the conversion between units and storage is almost entirely done manually, which has the following main drawbacks: large footprint, low work efficiency, and high labor intensity. 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 disassembly and maintenance system for components in a truck frame maintenance line, 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: A railway freight car bogie includes a frame 1, which includes components 1A. The frame maintenance line 2 of the frame 1 includes a disassembly station 2A, an assembly station 2B, and a disassembly and maintenance system 3 for components 1A. The disassembly and maintenance system 3 includes a robot 3A, a component maintenance line 3B, and a storage warehouse 3C. The component maintenance line 3B includes a workstation 3B1 for components awaiting repair and a workstation 3B2 for components that have passed inspection. The same robot 3A can perform repairs on components 1A on the frame 1 at the disassembly station 2A. The system can disassemble and place the component 1A to be repaired at the repair line station 3B1, or assemble the good component 1A on the good structure 1 of the assembly station 2B. It can also cache the component 1A to be repaired at the disassembly station 2A or the good component 1A on the good line station 3B2 to the storage repository 3C, or place the component 1A to be repaired in the storage repository 3C at the repair line station 3B1, or assemble the good component 1A in the storage repository 3C on the good structure 1 of the assembly station 2B.

[0005] As a further aspect of the present invention: the robot 3A includes a general-purpose robot 3A1 and a ground rail 3A2.

[0006] As a further aspect of the present invention: the component inspection line 3B includes a straight inspection line 5 that is straight in the top view, the straight inspection line 5 including a work station 3B1 to be repaired at the beginning and a work station 3B2 to be properly repaired at the end.

[0007] As a further aspect of the present invention: the storage warehouse 3C includes end warehouses 3C1 located at both ends of the straight maintenance line 5.

[0008] As a further aspect of the present invention: the storage warehouse 3C includes a parallel warehouse 3C2 parallel to the straight maintenance line 5.

[0009] As a further aspect of the present invention: the end warehouse 3C1 or the parallel warehouse 3C2 both include multi-layer shelves 3C3.

The gripper 2C3 is installed at the bottom of the lifting and rotating device 2C2, which is installed on the self-propelled trolley 2C1. The self-propelled trolley 2C1 can run on the overhead track 2C4.

[0011] As a further aspect of the present invention: the frame maintenance line 2 includes a dual-station gantry robot maintenance line 2D, which includes a gantry robot 8, two disassembly stations 2A and two assembly stations 2B. When one of the two disassembly stations 2A and two assembly stations 2B is performing work, the other station is used for the conversion between the frame 1 waiting for work and the frame 1 that has completed work. The gantry robot 8 includes a large trolley 8A, a small trolley 8B, a lifting device 8C and a gripper 8D. The gripper 8D that can grip the frame 1 is installed at the bottom of the lifting device 8C. The lifting device 8C is installed on the small trolley 8B. The small trolley 8B can move laterally on the large trolley 8A, and the large trolley 8A can move longitudinally on the track.

[0012] As a further aspect of the present invention: the gantry robot 8 includes a disassembly gantry robot 81 for disassembly station 2A and an assembly gantry robot 82 for assembly station 2B.

[0014] In summary, compared with the prior art, the present invention creatively achieves fully automated conversion between units such as disassembly, inspection, assembly and storage of parts using only one general-purpose robot. Its main advantages are: small footprint, high work efficiency and high degree of automation. Attached Figure Description
