Description

Technical Field

[0001] This utility model relates to the field of rail transit testing equipment technology, and in particular to an electrical integrated test bench for rail transit. Background Technology

[0002] In the rail transit industry, the stability and reliability of electrical equipment are crucial to the safe operation of trains. The comprehensive electrical test bench for rail transit can test a variety of electrical equipment on rail transit vehicles.

[0003] The existing integrated electrical test bench for rail transit is inconvenient to move to the required location, which is time-consuming and labor-intensive. When using wheels to move it, the entire test bench is supported by the wheels, resulting in low stability. Furthermore, it is not convenient to protect the interfaces and buttons on the test bench when not in use, which makes them prone to accumulating dust and debris when exposed to the outside for a long time, affecting the stability of electrical connections. Therefore, the device has certain shortcomings. Utility Model Content

[0006] The adjustment assembly includes a fixed plate, which is fixedly connected to the rear side of the electrical test bench body. A threaded rod is rotatably connected to the bottom of the fixed plate, and a movable plate is threadedly connected to the outer wall of the threaded rod. The movable plate slides on the rear side of the electrical test bench body. Connecting plates are fixedly connected to both ends of the movable plate. A universal wheel with brake is connected to the bottom of the connecting plate. Limiting plates are fixedly connected to both sides of the electrical test bench body. The connecting plates slide outside the limiting plates. The top of the threaded rod passes through the fixed plate and is connected to a drive assembly.

[0007] As a further description of the above technical solution:

[0008] The protective winding assembly includes a fixed frame, which is fixedly connected to the top of the electrical test bench body. A drive rod is rotatably connected inside the fixed frame. A roller shutter is fixedly connected to the outer wall of the drive rod. A strap is fixedly connected to the end of the roller shutter away from the drive rod. Two sets of straps are symmetrically arranged. A limit rod is fixedly connected to the outer wall of the electrical test bench body. Two sets of limit rods are symmetrically arranged. One end of the drive rod passes through the side of the fixed frame and is connected to a transmission assembly.

[0009] As a further description of the above technical solution:

[0010] The transmission assembly includes a second worm gear, which is fixedly connected to one end of the drive rod. A fixing block is fixedly connected to the side of the fixing frame, and a second worm is rotatably connected inside the fixing block. The second worm meshes with the second worm gear.

[0011] As a further description of the above technical solution:

[0012] The drive assembly includes a first worm gear, which is fixedly connected to the top of the threaded rod.

[0020] 1. In this utility model, in the electrical integrated test bench for rail transit, the height of the universal wheel with brake is easily adjusted by the adjustment component. When the electrical test bench body needs to be moved, the universal wheel with brake is lowered for movement. When movement is not required, the universal wheel with brake is raised so that the bottom of the electrical test bench body is grounded, which is more stable and avoids damage caused by prolonged pressure on the universal wheel with brake.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figures 1-6 An embodiment of this utility model is provided: an electrical integrated test bench for rail transit, including an electrical test bench body 1, an adjustment component connected to the side of the electrical test bench body 1, and a protective winding component connected to the top of the electrical test bench body 1;

[0032] The adjustment assembly includes a fixed plate 2, which is fixedly connected to the rear side of the electrical test bench body 1. A threaded rod 6 is rotatably connected to the bottom of the fixed plate 2. A movable plate 7 is threadedly connected to the outer wall of the threaded rod 6. The movable plate 7 slides on the rear side of the electrical test bench body 1. Connecting plates 8 are fixedly connected to both ends of the movable plate 7. A universal wheel 18 with brake is connected to the bottom of the connecting plate 8. Limiting plates 9 are fixedly connected to both sides of the electrical test bench body 1. The connecting plate 8 slides outside the limiting plates 9. The top of the threaded rod 6 passes through the fixed plate 2 and is connected to a drive assembly to facilitate the rotation of the threaded rod 6.

[0033] The protective winding assembly includes a fixed frame 10, which is fixedly connected to the top of the electrical test bench body 1. A drive rod 11 is rotatably connected inside the fixed frame 10. A roller shutter 12 is fixedly connected to the outer wall of the drive rod 11. A strap 13 is fixedly connected to the end of the roller shutter 12 away from the drive rod 11. Two sets of straps 13 are symmetrically arranged. Two sets of limit rods 19 are fixedly connected to the outer wall of the electrical test bench body 1. One end of the drive rod 11 passes through the side of the fixed frame 10 and is connected to a transmission assembly. The transmission assembly includes a second worm gear 14, which is fixedly connected to one end of the drive rod 11. A fixing block 15 is fixedly connected to the side, and a second worm gear 16 is rotatably connected inside the fixing block 15. The second worm gear 16 meshes with a second worm wheel 14. The drive assembly includes a first worm wheel 3, which is fixedly connected to the top of the threaded rod 6. A drive motor 4 is fixedly connected to the top of the fixing plate 2, and a first worm gear 5 is fixedly connected to the output end of the drive motor 4. The first worm gear 5 meshes with the first worm wheel 3. A protective door 20 is connected to the front side of the electrical test bench body 1, and a handle 21 is fixedly connected to the outer wall of the protective door 20. A crank handle 17 is fixedly connected to one end of the second worm gear 16. The limiting plate 9 is T-shaped to make the movement of the connecting plate 8 more stable.

[0034] Working principle: In the integrated electrical test bench for rail transit, the drive motor 4 is started, which drives the first worm gear 5 to rotate. The first worm gear 5 drives the first worm wheel 3 to rotate, and the first worm wheel 3 drives the threaded rod 6 to rotate. The threaded rod 6 then drives the moving plate 7 to slide on the outer wall of the electrical test bench body 1, causing the connecting plates 8 on both sides to rise and fall along the limiting plate 9. This facilitates the adjustment of the height of the universal casters 18 with brakes. When the electrical test bench body 1 needs to be moved, the universal casters 18 with brakes are lowered for movement; when movement is not required, the universal casters 18 with brakes are raised, so that the bottom of the electrical test bench body 1 is connected to the limit plate 9. The ground is more stable and avoids damage caused by prolonged pressure on the caster wheel 18 with brake. Turning the crank handle 17 drives the second worm gear 16 to rotate, the second worm gear 16 drives the second worm wheel 14 to rotate, and the second worm wheel 14 drives the drive rod 11 to rotate, thus facilitating the unfolding of the roller shutter 12. Pulling one end of the roller shutter 12 downward and tying the strap 13 to the outside of the limit rod 19 protects the plugs and buttons on the electrical test bench body 1 from dust accumulation affecting the stability of the electrical connection. Turning the crank handle 17 in the opposite direction can roll up the roller shutter 12, making it convenient to use the electrical test bench body 1.
