[0021] The present invention provides a live wire insulator replacement tool for electric power, aiming to design a live wire insulator replacement tool for electric power that integrates a supporting wire and a tightening wire.

[0022] The live wire insulator replacement tool for electric power proposed by the present invention will be described in the following specific embodiments:

[0023] In the technical solution of this embodiment, Figure 1 , Figure 2 , Figure 4 As shown, a live wire insulator replacement tool for electric power includes: a small crossarm 10, a wire support 20 and a wire tensioner 30, wherein the small crossarm 10 is used to be fixed on the original crossarm; the wire support 20 is fixed on the small crossarm 10; one end of the wire tensioner 30 is connected to the small crossarm 10, and the other end is used to connect the wire 21; wherein the wire support 20 includes an insulator 21, a bracket 22, an anti-slip structure 23, and a fixing frame 24, wherein the fixing frame 24 is fixed on the small crossarm 10, the bracket 22 is fixed on the fixing frame 24, the insulator 21 is fixed on the bracket 22, and the anti-slip structure 23 is fixed on the insulator 21.

[0024] Working principle: When replacing the conductor insulator, first conduct an on-site survey to determine its fixed position. After starting the operation, fix the small cross arm 10 on the original cross arm, and the anti-slip structure 23 of the conductor support 20 faces the direction of the conductor to be supported. Push the conductor to be supported into the groove of the insulator 21 in the anti-slip structure 23 through the one-way spring baffle. Then replace the old conductor insulator. After the insulating rod is pressed against the one-way spring baffle, push the supported conductor onto the replaced new insulator 21, fix it, and complete the maintenance operation.

[0025] When replacing the tension insulator, the conductor support 20 and the tensioner 30 are used together. The conductor support 20 supports the tension section jumper conductor, and the tensioner 30 relaxes the replaced tension insulator string, thereby replacing the tension insulator. Both the conductor support 20 and the tensioner 30 have insulation capabilities.

[0026] Specifically, the small cross arm includes a fixing clip, an oblique bar, and a cross bar. The fixing clip is used to be fixed on the original cross arm, one end of the oblique bar is fixed on the fixing clip, and the cross bar is fixed on the other end of the oblique bar; and the oblique bar is inclined relative to the cross bar and the fixing clip, so that the cross bar and the fixing clip are relatively misaligned, and the wire support and the tensioner are fixed on the cross bar at intervals. During operation, a certain operating space is reserved for easy operation.

[0027] Furthermore, if Figure 3 As shown, the tensioner 30 includes a positioning hook 31, a bracket 32, a tightening gear 33, a handle 34, and a wire clamp head 35; the positioning hook 31 is fixed on the small cross arm 10, the positioning hook 31 is fixed to the end of the bracket 32, the tightening gear 33 is rotatably arranged on the bracket 32, the handle 34 is fixed to the end of the tightening gear 33, and the wire clamp head 35 is wound around the tightening gear 33 through a wire 36. An insulating structure is provided at the connection between the positioning hook 31 and the bracket 32 ​​for insulation.

[0028] It can be understood that the tightening gear 33 is rotated by rotating the handle 34 to drive the wire 36 to move, thereby controlling the distance between the bracket 32 ​​and the wire clamp head 35 to achieve the tightening operation. The handle 34 is provided with a hole for operating the insulating rod.

[0029] Specifically, the tensioner 30 is made of high-strength insulating material and is lighter than a conventional galvanized steel tensioner.

[0030] Furthermore, the fixing frame 24 includes a fixing plate 241, a frame 242, and a fixing screw 243; the bracket 22 is fixed on the frame 242, the fixing plate 241 is movably arranged in the frame 242, the fixing screw 243 is connected to the frame 242, and is bolted to the frame 242, and one end of the fixing screw 243 located in the frame 242 abuts against the fixing plate 241.

[0031] Furthermore, the fixing plate 241, the frame 242, and the fixing screws 243 are made of galvanized steel.

[0032] Specifically, the fixing plate 241 is made of galvanized steel material; the contact area with the cross arm is increased, and during operation, the fixing screws 243 are tightened to achieve effective fixation with the cross arm. The rack 242 is made of galvanized steel material; the contact area with the cross arm is increased to achieve effective fixation with the cross arm. The fixing screws 243 are made of galvanized steel material; there are two fixing screws 243, and by tightening the fixing screws 243, the fixing effect of the fixing plate 241, the rack 242 and the cross arm is enhanced.

[0033] Furthermore, the insulator 21 is a porcelain or composite insulator 21 , and a groove for placing the conductor is provided on the top of the insulator 21 ; the anti-slip structure 23 is embedded in the groove of the insulator 21 .

[0034] Specifically, the insulator 21 serves as an insulator between the conductor and the cross arm, and its groove serves to fix the conductor, effectively preventing the conductor from falling off. The bracket 22 is used to support between the insulator 21 and the fixing bracket 24; the anti-falling device is made of galvanized steel material, and is used to push the conductor from the one-way spring baffle, which can effectively prevent the conductor from falling off.

[0035] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the present invention should be included in the protection scope of the present invention. Therefore, the protection scope of the present invention should be based on the protection scope of the claims.
