Description

Technical Field

[0001] The utility model relates to the technical field of live working, and more specifically, to a mechanical structure for live working on a 10kV distribution line. Background Art

[0002] During the live working process of general cable systems or power equipment systems, it is usually necessary to hang a grounding ring or a drainage ring on a live line, which requires live working such as stripping the insulating layer of the live line. In the current existing live working process, it is usually that the staff uses a manual wire stripper to clamp the wire and then wrap around the wire, and then manually push the cutting edge slowly to strip the insulating layer of the wire layer by layer. Although this operation method can meet the basic operation needs, its operation efficiency is low, and the operation process is time-consuming and laborious.

[0003] Chinese Patent Grant Publication No.: CN218997569U provides a live working wire stripper. After the cable is cut by the blade on the wire stripper, the cable is placed vertically on the cutter, and then the gripper squeezes the cutter into the cable, and then the cable or the wire stripper is pulled, and the cable can be vertically cut, so that the skin of the cable directly falls off, which is very convenient and greatly improves the work efficiency. However, there are still the following defects in the specific implementation process: the length of the cable to be stripped cannot be determined accurately during wire stripping, and it can only be judged by eyes, which may cause errors.

[0004] Therefore, a mechanical structure for live working on a 10kV distribution line is proposed for the above problems. Summary of the Utility Model

[0028] Embodiment:

[0029] Please refer to Figures 1-5 , a live working mechanical structure for a 10 kV distribution line, including an insulating housing 1. A scale 2 is fixedly connected to the upper end of the insulating housing 1. An operating mechanism 3 is rotatably connected to the left and right inner walls of the inner cavity of the insulating housing 1. A cutting mechanism 4 is fixedly connected to the left and right inner walls of the inner cavity of the insulating housing 1.

[0030] In this solution, insulation protection is carried out through the insulating housing 1. When working live, the operating mechanism 3 cooperates with the scale 2 to quickly cut the cable epidermis to a fixed length. The cutting mechanism 4 can horizontally cut the cut cable epidermis, quickly peel off the cable epidermis, and facilitate the high-voltage wiring work.

[0031] Please refer to Figures 2-4 , the operating mechanism 3 includes a rocker 31. The outer surface of the rocker 31 is rotatably connected to the inner surface of the right end of the insulating housing 1. A bidirectional screw 32 is fixedly connected to the left end of the rocker 31. The left end of the bidirectional screw 32 is rotatably connected to the left inner wall of the inner cavity of the insulating housing 1. Two operating components 33 are threadedly connected to the outer surface of the bidirectional screw 32. The operating component 33 includes a moving block 331. The inner surface of the moving block 331 is threadedly connected to the outer surface of the bidirectional screw 32. A connecting head 332 is fixedly connected to the lower end of the moving block 331. A pointer 333 is fixedly connected to the front end of the connecting head 332. A fixing component 334 is fixedly connected to the lower inner surface of the connecting head 332. The fixing component 334 includes an arc-shaped square tube 3341. The outer surface of the arc-shaped square tube 3341 is fixedly connected to the inner surface of the connecting head 332. Two sliding grooves 3342 are clamped in the inner cavity of the arc-shaped square tube 3341. A sliding pressure plate 3343 is slidably connected to the inner cavities of the two sliding grooves 3342. The inner surface of the sliding pressure plate 3343 is fixedly connected to the outer surface of the second arc-shaped clamping plate 336. A spring 3344 is arranged in the inner cavity of the arc-shaped square tube 3341. The left and right parts of the fixing component 334 are fixedly connected with first arc-shaped clamping plates 335. A second arc-shaped clamping plate 336 is fixedly connected to the inside of the fixing component 334. A first blade 337 is fixedly connected to the inner surface of the second arc-shaped clamping plate 336. A pull rod is fixedly connected to the outer surface of the second arc-shaped clamping plate 336. A high-voltage cable 34 is movably connected inside the two operating components 33.

[0032] In this solution, by shaking the rocker 31, the bidirectional screw 32 rotates under the action of the rocker 31. Since the two sections of threads on the outer surface of the bidirectional screw 32 are opposite, when the bidirectional screw 32 rotates, it can drive the two moving blocks 331 to move inward on the bidirectional screw 32 at the same time. At this time, the two pointers 333 will also move under the action of the two moving blocks 331. Just observe the distance between the two pointers 333 on the scale 2 to determine the length of the cut epidermis. After the length is confirmed, pull the pull rod so that the arc-shaped clamping plate II 336 can rotate 180° along the inner surface of the arc-shaped clamping plate I 335, and make the outer surface of the arc-shaped clamping plate II 336 closely adhere to the inner surface of the arc-shaped clamping plate I 335. At this time, the sliding pressure plate 3343 will drive along the inner cavity of the two sliding grooves 3342 under the drive of the arc-shaped clamping plate I 335, and the spring 3344 will be compressed during the sliding process. When the outer surface of the arc-shaped clamping plate II 336 closely adheres to the inner surface of the arc-shaped clamping plate I 335, make the inner surface of the arc-shaped clamping plate II 336 closely adhere to the outer surface of the high-voltage cable, and then release the pull rod. When the external force disappears, the sliding pressure plate 3343 will slide along the inner cavity of the two sliding grooves 3342 to the initial position under the action of the spring 3344, and will drive the arc-shaped clamping plate II 336 back to the initial position. The operating component 33 at the other end also needs to perform the above operations. Then, with the high-voltage cable as the axis, rotate the operating machine one week to cut the outer skin of the cable at a fixed length.

[0033] Please refer to Figure 1 and Figure 5 As shown in FIGS. and, the cutting mechanism 4 includes a connecting rod 41. The left and right ends of the connecting rod 41 are respectively fixedly connected to the left and right inner walls of the inner cavity of the insulating housing 1. The outer surface of the connecting rod 41 is movably connected with a sliding joint 42. The lower end of the sliding joint 42 is fixedly connected with an arc-shaped plate 43. The inner surface of the arc-shaped plate 43 is fixedly connected with a blade II 44. The outer surface of the arc-shaped plate 43 is fixedly connected with a push handle 45.

[0034] In this solution, by pushing the push handle 45 forward with the connecting rod 41 as the rotation axis, the arc-shaped plate 43 can be closely attached to the outer surface of the high-voltage cable. At this time, the blade II 44 will penetrate into the cable epidermis. Just move the push handle 45 horizontally and make the sliding joint 42 slide horizontally on the connecting rod 41 to horizontally cut open the cable epidermis that has been cut at a fixed length.

[0035] Working principle: When live working needs to be carried out using this machine, first shake the rocker 31. The two-way screw 32 rotates under the action of the rocker 31. Since the two sections of threads on the outer surface of the two-way screw 32 are opposite, when the two-way screw 32 rotates, it can drive the two moving blocks 331 to move inward on the two-way screw 32 at the same time. At this time, the two pointers 333 will also move under the action of the two moving blocks 331. Just observe the distance between the two pointers 333 on the scale 2 to determine the length of the cut epidermis. After the length is confirmed, pull the pull rod so that the arc-shaped clamping plate two 336 can rotate 180° along the inner surface of the arc-shaped clamping plate one 335, and make the outer surface of the arc-shaped clamping plate two 336 closely adhere to the inner surface of the arc-shaped clamping plate one 335. At this time, the sliding pressure plate 3343 will drive along the inner cavity of the two sliding grooves 3342 under the drive of the arc-shaped clamping plate one 335, and the spring 3344 will be compressed during the sliding process. When the outer surface of the arc-shaped clamping plate two 336 closely adheres to the inner surface of the arc-shaped clamping plate one 335, make the inner surface of the arc-shaped clamping plate two 336 closely adhere to the outer surface of the high-voltage cable. Then release the pull rod. When the external force disappears, the sliding pressure plate 3343 will slide along the inner cavity of the two sliding grooves 3342 to the initial position under the action of the spring 3344, and will drive the arc-shaped clamping plate two 336 to return to the initial position as well. The operating component 33 at the other end also needs to perform the above operations. Then, with the high-voltage cable as the axis, rotate the operating machine one week to cut the outer skin of the cable at a fixed length. Then, push the push handle 45 forward with the connecting rod 41 as the rotation axis so that the arc-shaped plate 43 can closely adhere to the outer surface of the high-voltage cable. At this time, the blade two 44 will penetrate into the cable epidermis. Just move the push handle 45 horizontally to make the sliding joint 42 slide horizontally on the connecting rod 41, and the cut cable epidermis can be horizontally cut open, and the cable epidermis can be peeled off for subsequent wiring work, which is safe and convenient.

[0036] The above is only a preferred specific embodiment of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
