Description

Technical Field

[0001] This utility model relates to the field of substation maintenance conductor technology, and in particular to a substation maintenance conductor traction device. Background Technology

[0002] In this context, with rapid economic development, society's demand for electricity is increasing daily. The scale of the power system is constantly expanding, including the number of substations, the capacity of power equipment, and the length of transmission lines. The importance of substation maintenance is becoming increasingly prominent, because substations are key nodes in the power system, and the normal operation of their equipment and conductors is directly related to the stability of the entire power network.

[0003] The substation maintenance conductor traction device consists of a traction main structure, a clamping device, a guiding device, and a control device. The clamping device clamps the conductor via a power mechanism, and the motor drives the device to move linearly through a transmission mechanism, transmitting force to the conductor to move it. During the process, the guide wheel guides the conductor along a predetermined path. Once the conductor reaches its destination, the motor stops, the clamp is released, and the traction ends.

[0004] In existing technologies, using guide wheels to pull conductors can lead to missed inspections and jamming during conductor maintenance. Traditional equipment clamping, which relies solely on a simple motor drive, cannot accurately fix the conductors. Therefore, a substation maintenance conductor traction device is proposed to solve the above problems. Utility Model Content

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the motor supported by the connecting plate drives the rotating disk to rotate, and the sliding bar also rotates accordingly. The shaft at the top of the sliding rotating plate drives the rotating disk to rotate. The rotating disk rotates and cooperates with the rotating disk, jointly driving the wire to be inspected to be pushed rhythmically. The rhythmic pushing of the wire can achieve an automated traction process, which can ensure that the wire's movement speed is uniform and stable, avoiding the situation where the wire's movement is unstable due to the lack of manual operation skills, thus affecting the maintenance effect.

[0017] 2. In this utility model, the second motor drives the gear to rotate, and under the interaction of the gear and the rack, the second sliding bar moves relative to each other, so that the sliding plate fixes the wire, so that the wire does not shift during maintenance. Fixing the wire can prevent it from moving accidentally during maintenance and reduce the risk of maintenance personnel being injured by the wire. Attached Figure Description

[0025] 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.

[0026] Reference Figures 1 to 3 The present invention provides an embodiment of a substation maintenance conductor traction device, comprising a support plate 1, the support plate 1 providing a solid mounting base for a propulsion mechanism 3 and a fixing mechanism 4, a support block 2 provided at the bottom rear side of the support plate 1, the support block 2 being used to support the upper structure, a propulsion mechanism 3 provided at the top of the support block 2, and a fixing mechanism 4 provided at the lower inner side of the support plate 1.

[0027] The propulsion mechanism 3 includes a connecting plate 301, which supports the first motor and connects components such as the second rotating disk 305, the first rotating plate 307, and the second rotating plate. The bottom of the connecting plate 301 is mounted on the top of the support block 2, and a rotating assembly is provided on the top of the connecting plate 301. The second rotating disk 305 is rotatably connected to the outer side of the propulsion mechanism 3, i.e., the inner side near the support plate 1. A connecting block 306 is provided on the outer side of the second rotating disk 305, i.e., the outer side away from the support plate 1. The connecting block 306 serves to connect and transmit power. The first rotating plate 307 is rotatably connected to the outer side of the intermediate shaft of the second rotating disk 305, i.e., the side away from the support plate 1. The connecting block 306 is driven to move through components such as the extension column and the rotating bar 309, thereby driving the propulsion mechanism 3. Rotating disk 2 305 rotates, and rotating plate 1 307 is rotatably connected to the outer side of the intermediate shaft of rotating disk 2 305. During the wire pulling process, rotating disk 2 305 cooperates with rotating disk 314 to pass the wire under maintenance through the middle of its outer groove, which plays the role of clamping and guiding the wire. An extension column 308 is provided on the top of rotating plate 1 307. 308 causes rotating bar 309 to rotate around it, thereby pushing connecting block 306 to drive rotating disk 2 305 to rotate. Rotating bar 309 is rotatably connected to the outer side of the top shaft of extension column 308. Rotating bar 309 is used to push connecting block 306. Rotating plate 2 310 is provided on the top of rotating plate 1 307. Intermittent component is provided on the outer side of the connecting shaft on the upper outer side of rotating plate 2 310.

[0028] The rotating assembly includes a motor 302, which drives a rotating disk 303 to rotate. The bottom of the motor 302 is fixedly mounted on the top of the connecting plate 301. The fixed output end of the motor 302 passes through the top of the inner side of the support plate 1 and is fixedly connected to the rotating disk 303. The rotating disk 303 drives a sliding bar 304 to rotate. The sliding bar 304 is provided on the outer side of the rotating disk 303 and is used to push 310. The outer side of the connecting plate 301 is fixedly connected to one side of the support plate 1, and the outer side of the motor 302 is fixedly connected to the outer side of the support plate 1.

[0029] The intermittent assembly includes a limiting spring 311, which, through its elasticity, pulls the rotating plate 307 to rotate within a certain range. The upper end of the limiting spring 311 is fixedly connected to the outer side of the connecting shaft on the upper outer side of the rotating plate 310. A fixing post 312 is provided on the outer side of the limiting spring 311, i.e., the end away from the rotating plate 310, fixing the limiting spring 311 to itself. The outer side of the fixing post 312, i.e., the side closer to the motor 302, is fixedly connected to the outer side of the connecting plate 301. A fixing shaft 313 is provided on the outer side of the connecting plate 301, and the outer side of the fixing shaft 313 passes through the inner side of the support plate 1. A rotating disk 314 is rotatably connected to the outer side of the fixing shaft 313, i.e., the side away from the support plate 1.

[0030] Reference Figure 1 , Figure 2 , Figure 4 The fixing mechanism 4 includes a connecting frame 401, which provides a stable mounting platform for the second motor 402, gear 403, limiting strip 406, sliding plate 405, and second sliding strip 404. The outer side of the connecting frame 401 is mounted on the inner side of the support plate 1. The second motor 402 is located on the rear side of the connecting frame 401. A gear 403 is located at the top of the middle part of the connecting frame 401 through the fixed output end of the second motor 402. The gear 402 is used to drive the gear 403 to rotate. The limiting strip 406 is fixedly connected to the inner side of the connecting frame 401, ensuring that the second sliding strip 404 can only move along a specific path. To prevent deviation or wobbling during movement, gear 403, through meshing with sliding bar 404, converts the circular motion of motor 2 into linear motion of sliding bar 404. A sliding plate 405 is slidably connected to the outer side of the limiting bar 406, away from the connecting frame 401. When sliding bar 404 moves under the drive of gear 403, sliding plate 405 moves accordingly, fixing the wire. Sliding bar 404 is fixedly connected to the outer side of sliding plate 405, away from the connecting frame 401. The outer rack of sliding bar 404 meshes with the outer side of gear 403. The outer side of connecting frame 401, away from sliding bar 404, is fixedly connected to the outer side of support block 2. The bottom of motor 2 402 is fixedly mounted on the top of support block 2.

[0031] Working principle: When inspecting the substation conductor, the conductor to be inspected is passed through the outer grooves of rotating disk 2 (305) and rotating disk 3 (314). The motor 1 (302) supported by the connecting plate 301 drives rotating disk 1 (303) to rotate in a circular motion. Sliding bar 1 (304) also rotates with rotating disk 1 (303). When rotating disk 1 (303) rotates, the shaft at the top of rotating disk 2 (310) slides, thereby driving rotating disk 1 (307) to rotate outside rotating disk 2 (305). At the same time, the elastic action between the two ends of the limiting spring 311 connecting rotating disk 2 (310) and fixed column 312 causes rotating disk 2 (310) to reciprocate within a certain range. Simultaneously, the movement of rotating disk 1 (307) drives the extension column 308 to move together. The rotating bar 309 connected to the top of the extension column 308 pushes the connecting block 306 to move, thereby driving rotating disk 2 (305) to rotate. At the same time, rotating disk 3 (314) rotates around the fixed shaft 313, thereby driving the conductor to be inspected to be pushed rhythmically, facilitating inspection and serving as a conductor traction function.

[0032] When a problem is detected during maintenance, the motor 402 supported by the support block 2 drives the sliding bar 404 to rotate. When the gear 403 rotates, the outer racks of the sliding bars 404 on both sides cause the sliding bars 404 to move relative to each other. As the sliding bars 404 move, the sliding plate 405 slides outside the limit bar 406 through the restriction of the connecting frame 401. This allows the sliding plate 405 to fix the wire and prevent it from shifting during maintenance, thereby improving maintenance efficiency.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
