Description

A ground conveyor with a rotating pallet for the maintenance of freight car bogies Technical Field

[0001] This invention belongs to the technical field of railway vehicle maintenance equipment, specifically a ground conveyor with a rotating pallet for the maintenance of freight car bogies. Background Technology

[0002] Currently, almost all bogie maintenance production lines in railway depots across the country adopt an overhead suspended structure. However, this structure requires a large number of ground-mounted columns, which not only occupy a significant amount of factory space but also affect aesthetics. Its main drawback is the potential safety hazard. While early bogie maintenance production lines before the advent of overhead suspended systems also used ground conveyors, and some depots are now developing bogie maintenance production lines using AGVs (Automated Guided Vehicles), the main components of all these ground conveyors are located above ground. The above-ground components are quite large, severely impacting the working space. 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 ground conveyor with a pallet rotation function for the maintenance of freight car bogies, 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 maintenance production line 2 for bogies 1 in a railway freight car depot and rolling stock plant includes a ground cover plate 2A, a cover plate groove 2B, a work station 2C, a conveyor 3, and a pallet 4. The bogie 1 includes a bolster 1A and components 1B. The ground cover plate 2A includes a middle cover plate 2A1 and an outer cover plate 2A2, with the gap between the middle cover plate 2A1 and the outer cover plate 2A2 equal to the width of the cover plate groove 2B. The work station 2C includes a disassembly station 2C1 and an assembly station 2C2. At the disassembly station 2C1, the components 1B to be repaired are disassembled, and at the assembly station 2C2, the good components 1B are assembled.

The cover plate groove 2B is located above the conveyor roller conveyor 3C. The pallet 4 includes a pallet body 4A, a slewing device 4B, and a bracket 4C for supporting the bolster 1A. The pallet body 4A includes two parallel I-beams 4A1 at the bottom and a base 4A2. The I-beams 4A1 include a bottom edge 4A1A and a web 4A1B located in the cover plate groove 2B. The bottom edge 4A1A rests on the conveyor roller 3C. The slewing device 4B includes a fixed ring 4B1, a rotating ring 4B2, and a rotation drive 4B3. The fixed ring 4B1 is mounted on the base 4A2, and the base 4A2 is fixedly connected to the top of the I-beams 4A1. The bracket 4C mounted on the rotating ring 4B2 includes a bolster support 4C1. The bolster 1A resting on the bolster support 4C1 can rotate relative to the fixed ring 4B1 through the rotation drive 4B3. The bolster 1A can carry the parts 1B through the conveyor 3 to realize the transportation of the bogie 1 between various working positions 2C.

[0005] As a further aspect of the present invention: the conveyor 3 includes a rotary conveyor 3B, the rotary conveyor 3B includes a rotary table 3B1 and a conveyor roller 3C installed on the rotary table 3B1, and the pallet 4 can be switched between two orthogonal linear conveyors 3A through the rotary conveyor 3B.

The power receiving device 5A includes a flat cable 5A1. The web plate 4A1B includes a web groove 4A1B1. One end of the flat cable 5A1 can pass through the web groove 4A1B1 and pass under the ground cover plate 2A through the cover plate groove 2B to be located above the ground.

[0010] As a further aspect of the present invention: the power supply device 5B includes a fixed-point power supply 5B1 located at the work station 2C.

[0011] As a further aspect of the present invention: the work station 2C includes a lifting device 6, which is located underground and includes a lifting frame 6A, a lifting electric cylinder 6B, and a lifting head 6C; the ground cover plate 2A includes a pusher hole 2A1A; the rotary device 4B includes a secondary guide column sleeve 7, which includes an outer sleeve 7A, an intermediate sleeve 7B, and a guide column 7C; the lifting head 6C of the lifting electric cylinder 6B installed on the lifting frame 6A can pass through the pusher hole 2A1A to lift the guide column 7C, thereby realizing the lifting and lowering of the bolster 1A at the work station 2C.

[0012] As a further aspect of the present invention: the tray 4 includes a positioning electric cylinder 8, which includes a positioning rod 8A. The positioning rod 8A can lock the outer sleeve 7A, the intermediate sleeve 7B and the guide post 7C, so that the rocker 1A on the rocker support 4C1 is limited to a set height and conveyed between each work station 2C by the conveyor roller 3C.

[0013] As a further aspect of the present invention: the component 1B includes a side frame 1B1, and the work station 2C includes a side frame precision positioning device 9 installed on the ground. The side frame precision positioning device 9 can achieve precise positioning of the side frame 1B1, which facilitates disassembly or assembly operations by robots or operators.

[0014] In summary, compared with the prior art, the present invention uses an underground friction accumulation roller as a conveyor, with only a cover plate groove on the ground that does not affect the movement of workers and vehicles. In addition, the present invention creatively adopts a lifting device fixed underground only at the work positions where the frame needs to be raised or lowered, which greatly simplifies the structure of the pallet. Moreover, it uses a fixed point power supply only at the work positions, avoiding the drawbacks of sliding contact line power supply. Its main advantages are: simple pallet structure and minimal space occupied above ground by the maintenance line. Attached Figure Description
