[0004] The above scheme has the following deficiencies in use: although the height of the traction box can be adjusted, the angle of the traction box cannot be adjusted after the traction box is lifted to the height, thereby affecting the maintenance work of the workers, and therefore, the application provides an adjustable subway traction box maintenance lifting device to solve the above problems. Content of the utility model

[0005] The application aims to provide an adjustable subway traction box maintenance lifting device to solve the problems in the background art.

[0006] To achieve the above-mentioned purpose, the application provides the following technical scheme:

[0007] An adjustable subway traction box maintenance lifting device includes a frame frame. A motor is installed at the bottom of the middle position of the frame frame. A threaded rod is fixedly connected to the output end of the motor. The top end of the threaded rod is rotatably connected to the bottom surface of the top end of the frame frame. A movable plate is threadedly connected to the outer surface of the threaded rod and is slidably connected to the outside of the frame frame. A carrier plate is fixedly connected to one side of the movable plate. A connecting column is rotatably connected to the upper surface of the carrier plate. A support plate is fixedly connected to the top end of the connecting column. A gear plate is fixedly connected to the bottom surface of the support plate. A motor is installed on the carrier plate. A gear is installed at the output end of the motor. The gear meshes with the gear plate.

[0012] In a further embodiment, the diameter of the toothed disc is four times the diameter of the gear.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This application utilizes a motor, a movable plate, a frame, and a carrier plate in coordination. The motor's operation causes the movable plate to rise, while the carrier plate simultaneously raises and lowers the pallet, thus adjusting the height of the traction box. Furthermore, the connection column, motor, gears, and gear disc work together. The motor's operation causes the gears to rotate the gear disc, which in turn drives the pallet to rotate, allowing for angle adjustment of the traction box. This facilitates maintenance work on the traction box. Support wheels provide support for the pallet, preventing lateral deviation during rotation. Attached Figure Description

[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0021] Please see Figs. 1-3 In this utility model, an adjustable subway traction box maintenance lifting device includes a frame frame 1. A motor 2 is provided at the bottom of the middle position of the frame frame 1. A base plate 11 is fixedly connected to the bottom end of the frame frame 1. The upper surface of the base plate 11 is connected to the bottom surface of the motor 2. The base plate 11 can support the frame frame 1 and fix the motor 2.

[0022] A threaded rod 5 is fixedly connected to the output end of motor 2. The top end of the threaded rod 5 is rotatably connected to the bottom surface of the top end of frame 1. A movable plate 4 is threadedly connected to the outer surface of the threaded rod 5, and the movable plate 4 is slidably connected to the outside of frame 1. A carrier plate 9 is fixedly connected to one side of the movable plate 4. A connecting column 15 is rotatably connected to the upper surface of the carrier plate 9. A support plate 8 is fixedly connected to the top end of the connecting column 15. When motor 2 is working, the threaded rod 5 will rotate on the movable plate 4, and the movable plate 4 will drive the carrier plate 9 to move. The support plate 8 can then drive the traction box to adjust its height.

[0023] Two top plates 10 are fixedly connected to the bottom surface of the carrier plate 9. Each top plate 10 is fixedly connected to the bottom end of a support plate 3. Each support plate 3 is slidably connected to the left side of the frame 1. By using the cooperation between the top plate 10 and the support plate 3, one side of the carrier plate 9 can be supported, thereby enhancing the load-bearing capacity of the carrier plate 9.

[0024] A geared disc 16 is fixedly connected to the bottom surface of the pallet 8. A motor 13 is installed on the carrier plate 9. A gear 12 is installed at the output end of the motor 13. The gear 12 meshes with the geared disc 16. The operation of the motor 13 can drive the gear 12 to rotate, which in turn drives the geared disc 16 to rotate. The geared disc 16 will then drive the pallet 8 to deflect, thereby completing the deflection of the traction box and facilitating the maintenance work of the traction box by the staff.

[0025] The diameter of the gear 16 is four times that of the gear 12, which ensures that the gear 12 drives the gear 16 to rotate slowly and smoothly.

[0026] The toothed disc 16 is equipped with support wheels 14 arranged at equal intervals, and the support wheels 14 are in contact with the upper surface of the carrier plate 9. The support wheels 14 can support the pallet 8, ensuring that the pallet 8 is horizontal, so as to prevent the pallet 8 from breaking due to uneven force on the connecting column 15.

[0027] The upper surface of the pallet 8 is fixedly connected with a crash pad 7, which can prevent friction damage between the towing box and the pallet 8.

[0028] The upper surface of the pallet 8 has a ring of slots 17, and a baffle 6 is inserted into each slot 17. When the traction box is raised, lowered and rotated, the baffle 6 can be inserted into the slot 17 to block the traction box and prevent it from falling. When the staff performs maintenance work, the baffle 6 can be removed from the pallet 8.

[0029] The working principle of this application is as follows: When in use, the starting motor 2 drives the threaded rod 5 to reverse, the moving plate 4 will drive the carrier plate 9 to descend, and then the traction box can be moved onto the pallet 8. Then, the motor 2 is controlled to rotate forward, and the moving plate 4 will drive the carrier plate 9 to rise. When the traction box is lifted to a certain height, the starting motor 13 is started. The motor 13 will drive the gear 12 to rotate, and the gear 12 will drive the gear plate 16 to rotate. At the same time, the gear plate 16 will drive the pallet 8 to deflect, and the traction box on the pallet 8 will also rotate accordingly, which is conducive to the maintenance work of the staff.

[0030] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
