Description

Technical Field

[0001] This invention belongs to the field of railway vehicle maintenance equipment technology, specifically a maintenance line for railway passenger car bogies equipped with a gantry robot. Background Technology

[0002] Currently, due to personnel movement and the operation of vehicles transporting parts on the workshop floor, all EMU depots across the railway operate their structural maintenance production lines via overhead lines. There are currently only two overhead line operation methods: 1. Assembly line structure: Each workstation is connected by several rail-mounted carriers (such as self-propelled trolleys or other conveyors). Its main disadvantages are: 1. Workstations can only be located within the coverage area of ​​the conveyors, resulting in significant waste of factory space; 2. When a carrier malfunctions, both the carrier before and after it cannot move, causing obstruction. 2. Overhead crane structure: Because the winches use flexible steel wire ropes, they sway during operation, hindering rapid operation, posing safety hazards, and making automation difficult. Furthermore, the existing EMU depot structural maintenance line workshops have large spans, and the structures are bulky and heavy, making overhead cranes unsuitable. 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 maintenance line for railway passenger car bogies with a gantry robot, 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 workshop 2 for repairing bogies 1 in a railway passenger car depot and rolling stock plant includes a safety platform 2A, side longitudinal tracks 21, intermediate longitudinal tracks 22, and a bogie repair production line 2B. The bogie 1 includes components 1A and a frame 1B, with the frame 1B including a gripper interface 1B1. The side longitudinal tracks 21 and intermediate longitudinal tracks 22 are arranged longitudinally along the length of the workshop 2. The bogie repair production line 2B includes workstations 3 and a gantry robot 4. Workstations 3 include a disassembly station 3A and an assembly station 3B. Both disassembly stations 3A and assembly stations 3B include ground supports 3C. The disassembly station 3A can disassemble the components 1A to be repaired on the frame 1. Assembly station 3B can assemble good parts 1A; gantry robot 4 includes gripper 4A, large trolley 4B, small trolley 4C and lifting device 4D. Gripper 4A is installed at the bottom of lifting device 4D, lifting device 4D is installed on small trolley 4C, and small trolley 4C can move laterally on large trolley 4B; large trolley 4B includes large trolley body 4B1, side travel wheels 4B2, intermediate frame 4B3 and intermediate travel wheels 4B4. Side travel wheels 4B2 and intermediate frame 4B3 are installed on large trolley body 4B1, and intermediate travel wheels 4B4 are installed on intermediate frame 4B3. Large trolley 4B achieves longitudinal movement by the movement of side travel wheels 4B2 on side longitudinal track 21 and the movement of intermediate travel wheels 4B4 on intermediate longitudinal track 22. The gantry robot 4 can grasp the gripper interface 1B1 through the gripper 4A, so that the frame 1B can carry the parts 1A for operation; the gantry robot 4 can realize the arbitrary transportation of the frame 1 between various work stations 3 by the operation of the trolley 4C above the safety platform 2A.

[0005] As a further aspect of the present invention: the bogie maintenance production line 2B includes a double-line maintenance production line, wherein several workstations 3 in the double-line maintenance production line can be arranged in parallel in a "non" shape on both sides of the safety platform 2A; the intermediate longitudinal track 22 is installed on the columns on both sides of the safety platform 2A.

[0006] As a further aspect of the present invention: the same decomposition operation includes two decomposition stations 3A, and the same assembly operation also includes two assembly stations 3B; while one station is performing the operation, the other station performs the conversion between the completed frame 1B and the frame 1B to be operated.

[0007] As a further aspect of the present invention: the security platform 2A includes a cache platform of the storage structure 1, the gripper 4A includes a hook 4A1, the gripper interface 1B1 includes a process hole 1B1A, and the gantry robot 4 can automatically pick up and place the structure 1B on the cache platform by hooking the process hole 1B1A with the hook 4A1.

[0008] As a further aspect of the present invention: the ground support 3C includes a ground rotation device 3C1, which enables the frame 1 to rotate on the ground; the gantry robot 4 includes an aerial rotation device 4E, which is mounted on a lifting device 4D, enabling the frame 1 to rotate in the air; the lifting device 4D includes a multi-column multi-stage lifting device 4D1.

[0009] In summary, compared with the prior art, this invention greatly increases the rigidity of the large vehicle body by setting multiple intermediate frames on the large vehicle body. Moreover, when the large vehicle is running longitudinally, the trolley can always run above the safety platform, which can prevent the workpiece from falling. In addition, the lifting adopts a rigid structure, which not only avoids the swaying of the frame in the air, but also greatly improves the running speed. Furthermore, the innovative design of the transition track can automatically realize the transportation between different cross-workshops within the workshop. The work stations can be arranged according to the work process flow, or they can be arbitrarily arranged within the coverage area of ​​the large vehicle. The main advantages are: small footprint, low labor intensity, and high work efficiency. Attached Figure Description
