[0036] 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.

[0037] See appendix Figure 1 Appendix Figure 2 and attached Figure 5 This utility model discloses a maintenance tool for railway power distribution equipment, used for internal maintenance and repair of power distribution box 2, including: horizontal mounting strip 1 and vertical mounting strip 5;

[0038] The horizontal mounting strip 1 is detachably connected to the top wall of the transformer box 2. A horizontal mounting groove is provided on the side wall of the horizontal mounting strip 1, and a horizontal adjustment component 4 is installed in the horizontal mounting groove.

[0039] The top of the vertical mounting block 5 is connected to the power output end of the horizontal adjustment component 4. A vertical limiting groove is provided on the side wall of the vertical mounting block 5. A lifting adjustment component 6 is installed in the vertical limiting groove. An L-shaped mounting plate 7 is fixedly installed on the power output end of the lifting adjustment component 6. The L-shaped mounting plate 7 is connected to a push telescopic rod 8 and a miniature camera 9. The push telescopic rod 8 can enter the interior of the transformer box 2, and a hook component 10 is fixed to the telescopic end of the push telescopic rod 8.

[0040] To further optimize the above technical solution, an air jet connector 11 is fixedly inserted into one end of the L-shaped mounting plate 7, and one end of the air jet connector 11 is connected to an external air pump.

[0041] In use, the horizontal mounting strip 1 is securely fixed to the top of the transformer substation 2 using the magnetic strip 3. The horizontal adjustment assembly 4 is moved within the horizontal mounting slot and adjusted to a suitable horizontal position before being fixed. Then, the vertical mounting strip 5 is adjusted to the required height using the lifting adjustment assembly 6. The L-shaped mounting plate 7 is fixed to the lifting adjustment assembly 6, and the telescopic rod 8 is activated, driving the hook assembly 10 to precisely move to the maintenance area inside the transformer substation 2, facilitating the removal of wire ends or debris. Simultaneously, the miniature camera 9 transmits images in real-time, assisting the operator in observing the internal situation to accurately operate the hook assembly 10 to complete the maintenance task. It also controls the external air pump to activate, causing air to spray from the air jet connector 11 to clean dust inside the transformer substation 2.

[0042] See appendix Figure 3 The horizontal adjustment assembly 4 includes a first servo motor 401 and a horizontal threaded rod 402. The first servo motor 401 is fixed on the inner wall of one end of the horizontal mounting groove, and one end of the horizontal threaded rod 402 is rotatably connected to the inner wall of the other end of the horizontal mounting groove through a rotating joint 403. The other end of the horizontal threaded rod 402 is fixedly connected to the output shaft of the first servo motor 401.

[0043] To further optimize the above technical solution, a transverse threaded block 404 is threadedly connected to the transverse threaded rod 402, and the transverse threaded block 404 is slidably connected in the transverse mounting groove.

[0044] To further optimize the above technical solution, an extension head 405 is fixedly installed on the transverse threaded block 404, and the top of the vertically installed strip 5 is fixed at the end of the extension head 405 away from the transverse threaded block 404.

[0045] In use, the first servo motor 401 is started, and its output shaft drives the transverse threaded rod 402 to rotate. Since the transverse threaded block 404 is slidably connected in the transverse mounting slot and threadedly connected to the transverse threaded rod 402, the rotation of the transverse threaded rod 402 will drive the transverse threaded block 404 to move laterally along the transverse mounting slot. The transverse threaded block 404 drives the vertical mounting strip 5 to move synchronously through the extended column head 405, thereby realizing the transverse position adjustment.

[0046] See appendix Figure 4 The lifting adjustment assembly 6 includes a second servo motor 601 and a vertical lead screw 602. The second servo motor 601 is fixed on the inner wall of one end of the vertical limiting groove. One end of the vertical lead screw 602 is rotatably connected to the inner wall of the other end of the vertical limiting groove through a rotating seat 603. The other end of the vertical lead screw is fixedly connected to the output shaft of the second servo motor 601.

[0047] To further optimize the above technical solution, a lifting threaded block 604 is threadedly connected to the vertical lead screw 602, and an L-shaped mounting plate 7 is fixed on the lifting threaded block 604.

[0048] In use, the second servo motor 601 is started, and its output shaft drives the vertical lead screw 602 to rotate on the rotary seat 603. Because the lifting threaded block 604 is threadedly connected to the vertical lead screw 602 and is limited by the vertical limiting groove, the rotation of the vertical lead screw 602 will drive the lifting threaded block 604 to move up and down along the vertical limiting groove. The lifting threaded block 604 then drives the L-shaped mounting plate 7 fixed on it to move up and down synchronously, realizing the vertical position adjustment.

[0049] To further optimize the above technical solution, the hook assembly 10 includes a positioning joint 1001, which is fixed to the telescopic end of the push telescopic rod 8, and a positioning hook 1002 is fixedly installed on the positioning joint 1001.

[0050] When in use, in conjunction with the miniature camera 9 and controlling the horizontal adjustment component 4 and the lifting adjustment component 6 to observe and inspect the electrical components inside the transformer box 2, if a damaged connector or debris appears at the position directly in front of the miniature camera 9, the push telescopic rod 8 is adjusted to a suitable length so that the positioning connector 1001 reaches the damaged connector or the location of the debris. This allows the positioning hook 1002 fixed on the positioning connector 1001 to smoothly hook the target component, and then the push telescopic rod 8 is used to complete the subsequent pull-out action. Observation using the miniature camera 9 can magnify small areas, solving the problem of difficulty in observation with the naked eye. At the same time, it reduces the contact time with the electrical components inside the transformer box 2 during maintenance, increases safety, and solves the disadvantage of the small space making it difficult to pull out wire ends or debris while facilitating inspection. If a problem occurs directly in front of the miniature camera 9 during the inspection process, the push telescopic rod 8 can be controlled in time to move the positioning hook 1002 for handling.

[0051] To further optimize the above technical solution, the telescopic rod 8 is pushed through the L-shaped mounting plate 7 and slidably connected to the L-shaped mounting plate 7.

[0052] To further optimize the above technical solution, a magnetic strip 3 is fixed to the bottom surface of the horizontal mounting strip 1, and the horizontal mounting strip 1 is attached to the top wall of the transformer box 2 by the magnetic strip 3.

[0053] This utility model can be firmly fixed to the top of the transformer box 2 by magnetic strip 3, which is convenient for disassembly and carrying. The horizontal adjustment component 4 and the lifting adjustment component 6 can flexibly adjust the horizontal and vertical positions to accurately locate the maintenance parts. At the same time, the telescopic rod 8 drives the hook component 10 to accurately hook out wire ends or debris. The miniature camera 9 provides real-time assistance for observation, improving the accuracy of operation and enhancing the convenience and safety of maintenance.
