Description

Technical Field

[0001] This utility model relates to the field of locomotive maintenance equipment technology, and in particular to a maintenance lifting platform for locomotive maintenance. Background Technology

[0002] Maintenance lifts are commonly used for the repair and maintenance of locomotives (motorcycles). They can raise the locomotive to a suitable working height for maintenance technicians, reducing the burden on their lower backs. They are an important tool for locomotive maintenance and can greatly improve work efficiency and safety.

[0003] A search revealed a Chinese patent with authorization number CN221720397U, which discloses a limiting mechanism for a motorcycle repair lifting platform. The mechanism includes a lifting platform with two parallel limiting plates, one and the other, arranged in an arc-shaped cross-section. A placement groove is provided on the lifting platform, containing a movable plate. An installation groove is formed on the inner wall of the placement groove, containing a pushing cylinder. A moving assembly is provided on the upper surface of the movable plate, comprising a lead screw, a stepper motor, and two mounting seats. The output end of the stepper motor extends into the mounting seats and connects to the lead screw. A sliding seat is fitted onto the lead screw. The first limiting plate is connected to the sliding seat. One end of the second limiting plate is placed on the movable plate. A horizontal plate is located between the first and second limiting plates. An extension plate is provided in the docking groove, slidingly connected to the docking groove. Compared to existing technologies, this invention increases the mobility of the repair platform and reduces operating costs for businesses.

[0004] The limiting mechanism for a motorcycle maintenance lifting platform in the aforementioned patent has the following shortcomings: it is inconvenient to replace the first limiting plate and the second limiting plate; different models of motorcycles have different tire sizes, and the aforementioned device can only fix motorcycles with specific tire sizes, thus limiting the applicability of the maintenance platform and failing to meet the maintenance needs of different models of motorcycles. Therefore, it is necessary to design a maintenance lifting platform for motorcycle maintenance to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a maintenance lifting platform for locomotive maintenance.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A maintenance lifting platform for locomotive repair and maintenance includes a scissor lift. The lifting platform of the scissor lift has a first mounting slot and a second mounting slot at each end. A first mounting box is disposed in the first mounting slot and is fixedly connected to the lifting platform of the scissor lift. A second mounting box is disposed in the second mounting slot and is slidably connected to the lifting platform of the scissor lift. Both the first and second mounting boxes have a first fixing plate and a second fixing plate inside. The two first fixing plates are fixedly connected to the first and second mounting boxes respectively. Two sleeve plates are fixedly connected to the bottom inner walls of both the first and second mounting boxes. A limiting rod passes through the sleeve plate and is slidably connected to the sleeve plate. Both the first and second fixing plates have two slots, and a common insert plate is disposed in both slots. The first, second, and insert plates all have holes adapted to the limiting rods. A limiting plate is fixedly connected to the top of the insert plate. The use of the moving limiting plate limits the movement of the insert plate. This technical means allows the limiting rod to be inserted into the holes on the first, second, and insert plates when the upper limit plate on the second fixed plate is moved towards the limiting plate on the first fixed plate. This limits the position of the insert plate and fixes its position, thus installing the limiting plate. When the limiting plate on the second fixed plate moves away from the limiting plate on the first fixed plate, the limiting rod can be removed from the insert plate on the first and second fixed plates, releasing the limiting of the insert plate and allowing it to be removed. This effectively solves the problem mentioned in the background art: the inconvenience of replacing the first and second limiting plates, the different tire sizes of different motorcycle models, and the fact that the above device can only fix motorcycles with specific tire sizes, thus limiting the applicability of the maintenance platform and failing to meet the maintenance needs of different motorcycle models. This achieves the technical effect of quickly installing and removing the limiting plates, effectively saving time and manpower. By flexibly replacing the limiting plates, it can be compatible with different specifications of motorcycle tires, expanding the applicability of the maintenance platform.

[0008] Preferably, the bottom inner walls of the first and second mounting boxes are each fixedly connected to two square plates. The square plates have holes that are adapted to the limiting rods. The limiting rods are slidably connected to the square plates. A ring is provided on the side of the sleeve plate near the square plates. The ring is fixedly connected to the outer wall of the limiting rods. A spring is provided between the square plates and the rings. The spring is sleeved on the limiting rods.

[0009] Preferably, a first drive screw is provided in both the first mounting box and the second mounting box. The two first drive screws pass through one side of the first mounting box and the second mounting box respectively. A first screw nut is fitted on both first drive screws. The first screw nut is adapted to the first drive screw. The first screw nut is fixedly connected to the second fixing plate.

[0010] Preferably, the first mounting box and the second mounting box are each provided with a first handle on a side that is far apart from each other, and the first handle is fixedly connected to the first drive screw.

[0011] Preferably, both the first mounting box and the second mounting box are provided with two second guide rods inside. The second guide rods are fixedly connected to the first mounting box and the second mounting box, and the second guide rods pass through the second fixing plate. The second fixing plate is slidably connected to the second guide rods.

[0012] Preferably, a first movable plate is fixedly connected to the bottom of the second mounting box, a second lead screw nut is mounted on the first movable plate, the second lead screw nut is fixedly connected to the first movable plate, a second drive lead screw is mounted on the second lead screw nut, the second drive lead screw is adapted to the second lead screw nut, the second drive lead screw passes through one side of the lifting platform of the scissor lift, the second drive lead screw is rotatably connected to the lifting platform of the scissor lift, and a second handle is fixedly connected to one side of the second drive lead screw.

[0013] Preferably, both ends of the first movable plate are provided with first guide rods, the first movable plate is slidably connected to the first guide rods, and the first guide rods are fixedly connected to the lifting platform of the scissor lift.

[0014] The beneficial effects of this utility model are as follows:

[0015] Because of the technical means of limiting the insertion plate during the movement of the limiting plate, when the limiting plate on the second fixed plate is moved towards the limiting plate on the first fixed plate, the limiting rod can be inserted into the holes on the first fixed plate, the second fixed plate, and the insertion plate, thus limiting the insertion plate and fixing its position. After the limiting plate is installed, when the limiting plate on the second fixed plate moves away from the limiting plate on the first fixed plate, the limiting rod can be removed from the insertion plate on both the first and second fixed plates, releasing the limitation on the insertion plate and allowing the insertion plate to be inserted. Removing the limiting plate effectively solves the problem mentioned in the background technology that it is inconvenient to replace the first and second limiting plates. Different models of motorcycles have different tire sizes, and the above device can only fix motorcycles with specific tire sizes, which limits the applicability of the maintenance platform and cannot meet the maintenance needs of different models of motorcycles. This allows for the quick installation and removal of the limiting plate, effectively saving time and manpower. By flexibly replacing the limiting plate, it can be compatible with different specifications of motorcycle tires, thus expanding the applicability of the maintenance platform.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-6A maintenance lifting platform for locomotive repair and maintenance includes a scissor lift 1. The lifting platform of the scissor lift 1 has a first mounting slot 2 and a second mounting slot 3 at both ends. A first mounting box 4 is disposed in the first mounting slot 2 and is fixedly connected to the lifting platform of the scissor lift 1. A second mounting box 5 is disposed in the second mounting slot 3 and is slidably connected to the lifting platform of the scissor lift 1. Both the first mounting box 4 and the second mounting box 5 have a first fixing plate 6 and a second fixing plate 7 inside. The two first fixing plates 6 are respectively fixed... The first mounting box 4 and the second mounting box 5 are fixedly connected. Two sleeve plates 8 are fixedly connected to the bottom inner walls of both the first mounting box 4 and the second mounting box 5. A limiting rod 9 passes through the sleeve plate 8 and slides along the sleeve plate 8. Two slots 10 are opened on both the first fixing plate 6 and the second fixing plate 7, and the same insert plate 11 is installed in each slot 10. Holes matching the limiting rod 9 are opened on the first fixing plate 6, the second fixing plate 7, and the insert plate 11. A limiting plate 12 is fixedly connected to the top of the insert plate 11. Due to the use of the moving limiting plate, [the following is possible]: The technical means of limiting the insertion plate allows the limiting rod to be inserted into the holes on the first, second, and insertion plates when the upper limiting plate on the second fixed plate moves towards the limiting plate on the first fixed plate. This limits the insertion plate and fixes its position, thus installing it. When the limiting plate on the second fixed plate moves away from the limiting plate on the first fixed plate, the limiting rod can be removed from the insertion plate on both the first and second fixed plates, releasing the limitation on the insertion plate and allowing it to be removed. This effectively solves the problem mentioned in the background art: the inconvenience of replacing the first and second limiting plates, the different tire sizes of different motorcycle models, and the limitation that the above device can only fix motorcycles with specific tire sizes, thus restricting the applicability of the maintenance platform and failing to meet the maintenance needs of different motorcycle models. This achieves the technical effect of quickly installing and removing the limiting plates, effectively saving time and manpower. By flexibly replacing the limiting plates, it can be compatible with different specifications of motorcycle tires, expanding the applicability of the maintenance platform.

[0025] In this utility model, two square plates 13 are fixedly connected to the bottom inner walls of the first mounting box 4 and the second mounting box 5. The square plates 13 have holes adapted to the limiting rod 9. The limiting rod 9 is slidably connected to the square plates 13. A ring 14 is provided on the side of the sleeve plate 8 near the square plates 13. The ring 14 is fixedly connected to the outer wall of the limiting rod 9. A spring 15 is provided between the square plates 13 and the ring 14. The spring 15 is sleeved on the limiting rod 9. By providing the spring 15, when the second fixed plate 7 presses the limiting rod 9 and moves the limiting rod 9, the ring 14 will move, and the ring 14 will press the spring 15 to contract. When the second fixed plate 7 does not apply pressure to the limiting rod 9, the contracted spring 15 will gradually extend, so that the limiting rod 9 returns to its original position.

[0026] In this utility model, a first drive screw 16 is provided in both the first mounting box 4 and the second mounting box 5. The two first drive screws 16 pass through one side of the first mounting box 4 and the second mounting box 5 respectively. A first screw nut 17 is sleeved on both first drive screws 16. The first screw nut 17 is adapted to the first drive screw 16. The first screw nut 17 is fixedly connected to the second fixing plate 7.

[0027] In this utility model, the first mounting box 4 and the second mounting box 5 are each provided with a first handle 18 on a side that is far apart from each other, and the first handle 18 is fixedly connected to the first drive screw 16.

[0028] In this utility model, the first mounting box 4 and the second mounting box 5 are each provided with two second guide rods 24. The second guide rods 24 are fixedly connected to the first mounting box 4 and the second mounting box 5. The second guide rods 24 pass through the second fixing plate 7. The second fixing plate 7 is slidably connected to the second guide rods 24. When the second fixing plate 7 moves, it will move along the second guide rods 24 to ensure the stability of the second fixing plate 7 when it moves.

[0029] In this utility model, a first movable plate 19 is fixedly connected to the bottom of the second mounting box 5. A second lead screw nut 20 is provided on the first movable plate 19. The second lead screw nut 20 is fixedly connected to the first movable plate 19. A second drive screw 21 is provided on the second lead screw nut 20. The second drive screw 21 is adapted to the second lead screw nut 20. The second drive screw 21 passes through one side of the lifting platform of the scissor lift 1. The second drive screw 21 is rotatably connected to the lifting platform of the scissor lift 1. A second handle 22 is fixedly connected to one side of the second drive screw 21.

[0030] In this utility model, both ends of the first movable plate 19 are provided with first guide rods 23. The first movable plate 19 is slidably connected to the first guide rods 23. The first guide rods 23 are fixedly connected to the lifting platform of the scissor lift 1. When the first movable plate 19 moves, it will move along the first guide rods 23 to ensure the stability of the first movable plate 19 when it moves.

[0031] Working Principle: In use, with the scissor lift platform 1 at its lowest position, place the scooter on the platform. Turn the first handle 18 to rotate the first drive screw 16. The first drive screw 16 will then move the first screw nut 17, which in turn will move the second fixing plate 7. The second fixing plate 7 will then move the insert plate 11, which will in turn move the limiting plate 12 closer to another limiting plate 12. This will limit and fix the scooter wheels, allowing the scissor lift platform 1 to rise, adjust the height, and perform maintenance work. Other... When maintaining a locomotive with a specific wheelbase, the second handle 22 can be rotated. The second handle 22 will then rotate the second drive screw 21, which in turn will move the second screw nut 20. The second screw nut 20 will then move the first moving plate 19 along the first guide rod 23. The movement of the first moving plate 19 will then move the second mounting box 5, allowing adjustment of the distance between the second mounting box 5 and the first mounting box 4. This accommodates locomotives with different wheelbases. When maintaining locomotives with other tire sizes, the insert plate 11 on the limiting plate 12 corresponding to the locomotive's tire size is inserted into the slot 10. In the process of moving the second fixing plate 7, the second fixing plate 7 gradually fits onto the limiting rod 9. The limiting rod 9 then passes through the holes on the second fixing plate 7 and the insert plate 11, thus restricting the position of the insert plate 11. This allows the limiting plate 12 on the second fixing plate 7 to be installed. The second fixing plate 7 continues to move until it abuts against the limiting rod 9. At this point, the continued movement of the second fixing plate 7 will drive the limiting rod 9 to move, causing it to enter the holes on the first fixing plate 6 and the insert plate 11. This restricts the position of the insert plate 11 on the first fixing plate 6, thus allowing the first fixing plate to be installed. The limiting plate 12 on the first fixed plate 6 will also drive the ring 14 to move during the movement of the limiting rod 9. The ring 14 will compress the spring 15, causing the spring 15 to contract. When the limiting plate 12 needs to be removed, the second fixed plate 7 is moved away from the first fixed plate 6 until it reaches the farthest point. The contracted spring 15 will then extend, allowing the ring 14 to return to its initial position, which in turn allows the limiting rod 9 to return to its initial position. The limiting rod 9 is no longer in the holes on the first fixed plate 6, the second fixed plate 7, and the insert plate 11, so the limiting can be released. The insert plate 11 can then be removed from the slot 10, and the limiting plate 12 can be removed and replaced.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
