Description

Technical Field

[0001] This utility model relates to the field of subway vehicle maintenance, specifically a subway vehicle maintenance platform. Background Technology

[0002] Subways are high-speed, high-capacity, electrically powered rail transit systems built in cities. They can greatly alleviate urban traffic pressure and have become an important means of transportation in modern cities. Subway cars require maintenance after a period of use to ensure their safety during operation. When maintaining the air conditioning, lighting, and internal circuits on the roof of the subway car, maintenance personnel need to use a lifting platform to assist in the work due to the height of the roof.

[0003] Existing maintenance platforms are often insufficient to meet the maintenance needs of various vehicle types. When vehicles of different heights need to be inspected, it is often necessary to replace them with dedicated maintenance platforms, which is not only cumbersome and time-consuming, but also increases maintenance costs and seriously affects maintenance efficiency. At the same time, the maintenance platforms lack precise positioning and adaptive adjustment functions during the maintenance process, which is not conducive to the smooth progress of maintenance work. Therefore, we propose a subway vehicle maintenance platform to solve the above problems. Utility Model Content

[0021] According to one embodiment of the present invention, in conjunction with the appended drawings Figure 1-5 As shown.

[0022] A subway vehicle maintenance platform includes a base 1, with four movable seats 11 connected to the bottom surface of the base 1. A height adjustment frame 3 is connected to the upper surface of the base 1. A motor slot 13 is formed on the bottom surface of the base 1, and a height adjustment drive motor 17 is connected to the inner wall of the motor slot 13. A groove 19 is formed on the bottom surface of the base 1, and an angle adjustment drive motor 20 is connected to the inner wall of the groove 19. An electro-hydraulic telescopic rod 22 is connected to the output end of the angle adjustment drive motor 20. An angle adjustment seat 16 is connected to the bottom surface of the electro-hydraulic telescopic rod 22, and two anti-slip pads 2 are connected to the bottom surface of the angle adjustment seat 16. When maintenance personnel need to perform maintenance work on different height parts of the subway vehicle, they can start the height adjustment drive motor 17 through the touch panel 14, which drives the threaded rod 6 to rotate and cooperate with the limit slider 5 in the limit slide groove 4. The limit slider 5 is constrained by the limit slide groove 4 and can only move along the slide groove. The platform moves upwards, thereby driving the support plate 7 connected between the two limit sliders 5 and the maintenance frame 8 on the support plate 7 to rise and fall along the height direction. If the maintenance work requires operation of the subway car from different angles, the maintenance personnel can also set the angle adjustment command on the touch panel 14 and start the electric hydraulic telescopic rod 22 to extend and retract. Under the guidance of the bottom limit slide rail 23 of the base 1 and the upper limit slide column 24 of the angle adjustment seat 16, the angle adjustment drive 20 is used as the fulcrum to achieve angle deflection. The angle change of the angle adjustment seat 16 drives the entire maintenance platform to produce a corresponding angle adjustment, thereby meeting the needs of maintenance personnel to carry out maintenance work from multiple angles. This allows the maintenance platform to flexibly deflect in height and angle, meeting the needs of maintenance personnel to carry out maintenance work on the vehicle from multiple angles, and improving the comprehensiveness and efficiency of the maintenance work.

[0023] In this embodiment, two limiting brackets 21 are snapped onto the outer surface of the angle adjustment drive 20. The outer surface of each limiting bracket 21 is connected to the inner wall of the groove 19. A cover plate 12 is bolted to the bottom surface of the motor groove 13. Two U-shaped seats 18 are snapped onto the outer surface of the height adjustment drive 17. The outer surface of each U-shaped seat 18 is connected to the inner wall of the motor groove 13. The height adjustment drive 17 can be fixed by the U-shaped seats 18. A limiting bracket is provided on the bottom surface of the base 1. The inner wall of the slide rail 23 is slidably connected to the limiting slide post 24. The bottom surface of the limiting slide post 24 is connected to the upper surface of the angle adjustment seat 16. The limiting slide rail 23 can restrict the movement trajectory of the limiting slide post 24. The inner wall of the height adjustment frame 3 is provided with two limiting slide grooves 4. The inner wall of each limiting slide groove 4 is slidably connected to a limiting slider 5. One of the limiting sliders 5 has a threaded rod 6 threadedly connected to its inner wall. The limiting slider 5 is constrained by the limiting slide groove 4 and can only move along the direction of the slide groove.

[0024] In this embodiment, one end of the threaded rod 6 passes through the limiting slide groove 4 and the base 1 in sequence and extends into the interior of the motor groove 13. One end of the threaded rod 6 is connected to the output end of the height adjustment drive 17. Through the threaded rod 6, the driving force of the height adjustment drive 17 can be converted into linear motion. The two limiting sliders 5 are connected to a support plate 7 on their side that is close to each other. The upper surface of the support plate 7 is connected to a maintenance rack 8. The maintenance rack 8 facilitates maintenance work for the staff. A protective door 9 is hinged to the front of the maintenance rack 8. A handle 10 is connected to the front of the protective door 9. A storage box 15 is connected to the inner wall of the maintenance rack 8. A touch panel 14 is connected to the inner wall of the maintenance rack 8. The touch panel 14 facilitates operation of the equipment for the staff.

[0025] Working principle: In use, the operator first uses the movable seat 11 to push the subway vehicle maintenance platform to the designated position. After reaching the predetermined position, the two anti-slip pads 2 on the bottom of the angle adjustment seat 16 make close contact with the ground, and the increased friction makes the maintenance platform stably positioned. When the maintenance personnel need to perform maintenance work on different height parts of the subway vehicle, they start the height adjustment drive motor 17 through the touch panel 14, which drives the threaded rod 6 to rotate and cooperate with the limit slider 5 in the limit slide groove 4. The limit slider 5 is constrained by the limit slide groove 4 and can only move along the slide groove direction, thereby driving the support plate connected between the two limit sliders 5. 7 and the maintenance frame 8 on the support plate 7 are raised and lowered along the height direction. If the maintenance work requires operation of the subway car from different angles, the maintenance personnel can also set the angle adjustment command on the touch panel 14, start the electric hydraulic telescopic rod 22 to extend and retract, and drive the angle adjustment seat 16 connected to it to achieve angle deflection with the angle adjustment drive motor 20 as the fulcrum under the guidance of the bottom limit slide rail 23 of the base 1 and the upper surface limit slide column 24 of the angle adjustment seat 16. The angle change of the angle adjustment seat 16 drives the entire maintenance platform to produce a corresponding angle adjustment, thereby meeting the needs of maintenance personnel to carry out maintenance work from multiple angles.

[0026] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
