Description

Technical Field

[0001] The utility model relates to the technical field of electric iron towers, in particular to a cable fixing device for electric iron towers which is easy to maintain. Background Art

[0002] Power towers are tower-shaped buildings used for power transmission and are very important facilities in the power sector. They are mainly built near outdoor power plants and distribution stations. The cables that transmit electrical energy are often installed and fixed on power towers through fixing devices.

[0003] For example, a Chinese patent (publication number: CN220527643U) discloses a cable fixing device for an electric power tower that is easy to maintain, comprising: a base plate for bearing a limiting effect, a cover plate rotatably connected to the inner side of the upper left end of the base plate, and movable rods that are equidistantly engaged and penetrated in the cover plate; further comprising: an adjusting rod is engaged and non-detachably connected to the inner side of the lower end of the base plate, and clamps are threadedly connected to the outer sides of the left and right ends of the adjusting rod; a worm gear is fixedly connected to the rear side of the lower left end of the cover plate, and a worm is meshedly connected to the lower right side of the worm gear; a spring is nested on the outer side of the lower end of the movable rod, and a pressure plate is fixedly connected to the lower side of the movable rod; a limiting rod, which is obliquely and symmetrically arranged inside the outer upper end of the cover plate. The cable fixing device for an electric power tower that is easy to maintain is easy to install and fix on the electric power tower, and is easy to shield and rust-proof some parts, easy to quickly clamp and fix and disassemble and maintain different cables, and easy to rotate against the wind to drive away birds.

[0004] The above-mentioned power tower cable fixing device which is easy to maintain still has certain shortcomings. The worm gear is rotated to press the pressure plate downward under the elastic force of the nested spring on the outer side of the lower end of the movable rod, so that the pressure plate drives the first anti-slip pad adhered and fixed on the inner side thereof to fit the outer side of the upper end of the cable, thereby facilitating the rapid clamping and fixing of different cables. However, the worm gear needs to be rotated to drive the worm wheel and the cover plate to rotate together. During the rotation of the cover plate, the rightmost pressure plate not only affects the rotation of the cover plate, but also fails to limit the cover plate after the rotation is completed, resulting in the cover plate being easy to rotate, affecting the fixing effect of the cable. Therefore, a power tower cable fixing device which is easy to maintain is proposed to solve the above-mentioned problems. Utility Model Content

[0033] See also Figure 4In order to facilitate the fixing of the box body 1, the fixing mechanism 4 in this embodiment includes a cavity 401 opened inside the box body 1, and the front of the inner cavity of the cavity 401 is rotatably connected with a worm 402 that penetrates and extends to the outside of the box body 1 through a bearing seat, and a second threaded rod 404 is rotatably connected between the left and right sides of the inner cavity of the cavity 401 through a bearing seat, and a worm wheel 403 meshing with the worm 402 is fixed on the outer surface of the second threaded rod 404, and two clamping plates 405 are threadedly connected to the outer surface of the second threaded rod 404. The rotation of the worm 402 drives the worm wheel 403 and the second threaded rod 404 to rotate together, so that the two clamping plates 405 move relative to each other at the same time.

[0034] The second threaded rod 404 has two threads with opposite directions. The second threaded rod 404 rotates to drive the two clamping plates 405 to move relative to or away from each other at the same time. A second rotating handle is fixed on the back of the worm 402 to facilitate the rotation of the second rotating handle.

[0035] In addition, a vertical plate is fixed between the upper and lower sides of the inner cavity of the cavity 401, and a sliding rod is fixed on the opposite sides of the two vertical plates. The splint 405 is slidably connected to the outer surface of the sliding rod to increase the stability of the splint 405 when it moves. A second rubber pad is fixed on the opposite side of the two splints 405 to increase the stability of the fixed box 1.

[0036] The fixing mechanism 4 in this embodiment rotates the second rotating handle to drive the worm 402 to rotate, and drives the worm wheel 403 and the second threaded rod 404 to rotate together, so that the two clamping plates 405 move relatively at the same time, and drive the second rubber pad to move together, and the second rubber pad abuts against the iron tower to fix the box body 1, thereby improving the stability during fixation.

[0037] The working principle of the above embodiment is:

[0038] (1) When it is necessary to clamp the cable, first insert the shell 301 into the box body 1, so that the insertion rod 311 is inserted into the interior of the slot 312, and the cable is clamped and fixed by the cooperation of the pressure plate 7 and the bottom plate 8. At this time, turn the first rotating handle, the first rotating handle drives the first threaded rod 303 to rotate in the threaded hole 302, and drives the push block 304 and the T-shaped rod to move together. The T-shaped rod will slide in the round hole to increase the stability of the push block 304 when it moves. When the push block 304 moves, it will push the two moving blocks 305 to move back to each other at the same time. The moving block 305 will drive the moving plate 306 to move together and squeeze the first telescopic rod 307 and the first spring 308. The moving plate 306 will also drive the clamping rod 309 to move together, so that the clamping rod 309 is clamped into the interior of the clamping slot 310, and the cover plate 2 is fixed to prevent affecting the fixing of the cable by the pressure plate 7 and the bottom plate 8.

[0039] (2) When the box body 1 needs to be clamped on the iron tower, the box body 1 is first placed on the iron tower, and the second rotating handle is turned. The second rotating handle drives the worm 402 to rotate. When the worm 402 rotates, it drives the worm wheel 403 to rotate, and the second threaded rod 404 is driven to rotate together through the worm wheel 403. Since the two sections of the second threaded rod 404 have opposite threads, the second threaded rod 404 rotates, driving the two clamping plates 405 to move relative to each other at the same time. The clamping plates 405 will slide on the sliding rod, thereby increasing the stability of the clamping plates 405 when moving. When the clamping plates 405 move, they will drive the second rubber pad to move together, and the second rubber pad will contact the iron tower to fix the box body 1, thereby improving the stability when fixing.
