Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1-6 As shown, the present invention is a clamping and securing operating rod for uninterrupted power transmission line operation.

[0021] Example 1 Please see Figure 1 , Figure 2 and Figure 4 In this invention, a technical solution is provided: a fixed base plate 1, an extendable and adjustable fixed insulating rod 2 is installed at the lower end of the fixed base plate 1, a first worm gear 103 is provided above the fixed base plate 1 to drive the fixed base 106 to rotate, and a second worm gear 105 is provided on the inner side of the fixed base 106 to drive the adjusting box 3 to rotate.

[0022] Furthermore, a first worm 102 is provided on the outer side of the first worm wheel 103 for meshing connection, and the first worm wheel 103 is fixedly connected to the fixed base 106; The lower end of the first worm gear 103 is provided with an annular plate, and the first worm gear 103 forms a close-fitting circular rotation motion within the fixed base plate 1 through the annular plate.

[0023] Furthermore, the second worm 105 is meshed with the second worm wheel 301, and the second worm wheel 301 is rotatably connected to the fixed base 106.

[0024] Furthermore, an auxiliary insulating rod 201 is threadedly connected to the lower end of the fixed insulating rod 2, and an insulating control handle 203 is threadedly connected to the lower end of the auxiliary insulating rod 201. Both the fixed insulating rod 2 and the auxiliary insulating rod 201 have through holes 202 on their inner sides for passing through the line to conduct electricity.

[0025] Specifically, firstly, based on the actual working height, auxiliary insulating rods 201 of corresponding length are installed on the inner sides of the fixed insulating rod 2 and the insulating control handle 203 respectively, so that the components are threadedly fastened. The power cable can be passed through the through hole 202 and passed through the inner sides of the fixed insulating rod 2 and the auxiliary insulating rod 201 respectively to connect with the insulating control handle 203, so that the first servo motor 101, the second servo motor 104 and the third servo motor 303 set at the upper end can be directly controlled through the insulating control handle 203.

[0026] The first worm gear 102 is meshed with the first worm wheel 103. When the first servo motor 101 is turned on and the first worm gear 102 is rotated, it can drive the first worm wheel 103 to rotate synchronously. An annular plate is provided at the lower end of the first worm wheel 103, allowing the first worm wheel 103 to rotate stably and securely against the inner side of the fixed base plate 1, thus driving the fixed base 106 fixedly mounted on the upper end of the first worm wheel 103 to rotate in a circular motion. The second worm gear 105 is meshed with the second worm wheel 301, allowing the second worm gear 102 to rotate when the second servo motor 104 is turned on. When the worm gear 105 is in operation, the entire adjusting box 3 rotates at an angle on the fixed base 106 via the second worm wheel 301. This allows for angle adjustment of the adjusting box 3 and its upper components. In conjunction with the special structure of the first worm gear 102 and the first worm wheel 103, as well as the second worm gear 105 and the second worm wheel 301, the first worm wheel 103 and the second worm wheel 301 can be prevented from moving independently. Afterward, the entire parallel groove clamp 4 is fitted onto the fixed guide plate 302 via the connecting lug 401, allowing for uninterrupted power supply operation of the high-voltage transmission line using the parallel groove clamp 4.

[0027] Example 2 This embodiment is derived based on Embodiment 1. Please refer to [link / reference]. Figure 2 , Figure 3 , Figure 4 and Figure 5In this invention, a technical solution is provided: a reciprocating screw 306 for lifting and lowering reciprocating motion is provided on the inner side of the adjusting box 3, a movable adjusting block 308 is movably connected to the upper end of the reciprocating screw 306, a movable locking block 3082 is provided on the inner side of the movable adjusting block 308, a parallel groove clamp 4 is provided on the upper side of the adjusting box 3, a fastening bolt 402 for driving the movable horizontal plate 403 to move up and down is provided on the inner side of the parallel groove clamp 4, and a first positioning wiring block 404 and a second positioning wiring block 405 are respectively provided on the upper side of the movable horizontal plate 403.

[0028] The right side of the inside of the regulating box 3 is equipped with a drive gear disk 304, the left end of the drive gear disk 304 is meshed with a driven gear disk 305, and the upper end of the driven gear disk 305 is equidistantly equipped with a fixed sleeve rod 3051.

[0029] Furthermore, an annular plate is provided at the lower end of the driven gear disk 305, and the driven gear disk 305 forms a close-fitting rotation structure in the adjusting box 3 through the annular plate. A positioning block 307 connected to the adjusting box 3 is provided below the driven gear disk 305.

[0030] Furthermore, the driven gear disk 305 is threadedly connected to the reciprocating lead screw 306, and a limit groove 3061 is provided on the inner side of the lower end of the reciprocating lead screw 306; The reciprocating lead screw 306 forms an engaging sliding structure on the positioning block 307 through the limiting groove 3061.

[0031] Furthermore, the movable adjusting block 308 is rotatably connected to the reciprocating lead screw 306, and the lower end of the movable adjusting block 308 is provided with a limiting vertical rod 3081 connected to the fixed sleeve rod 3051; The movable adjusting block 308 forms a nested sliding structure within the fixed sleeve 3051 via the limiting vertical rod 3081; The inner side of the movable adjusting block 308 is equidistantly equipped with damping springs 3083 that are connected to the movable locking block 3082. The movable locking block 3082 forms an elastic telescopic movement within the movable adjusting block 308 through the damping springs 3083.

[0032] Furthermore, the upper surface of the movable locking block 3082 is fitted with the fastening bolt 402, and the fastening bolt 402 is movably connected to the lower end of the movable horizontal plate 403; The movable horizontal plate 403 forms a locking lifting motion within the parallel groove clamp 4.

[0033] Specifically, in conjunction with Embodiment 1, after the overall length adjustment is completed, the parallel groove clamp 4, nested on the outer side of the fixed guide plate 302, is hung on the high-voltage transmission line. At this time, the third servo motor 303 is turned on to rotate the drive gear disk 304. Since the drive gear disk 304 is meshed with the driven gear disk 305, the rotation of the drive gear disk 304 can drive the driven gear disk 305 to rotate synchronously, and the driven gear disk 305 can rotate stably inside the adjustment box 3 through the annular plate set at the lower end. The driven gear disk 305 and the reciprocating screw... With a 306 threaded connection, the reciprocating screw 306 will move stably up and down on the positioning block 307 through the limiting groove 3061, so as to drive the movable adjusting block 308 to adjust its overall height. When the parallel groove clamp 4 is hung on the high-voltage transmission line, the fastening bolt 402 installed on the inner side of the parallel groove clamp 4 will be nested inside the movable adjusting block 308. Since the movable adjusting block 3082 and the damping spring 3083 are equidistantly arranged on the inner side of the movable adjusting block 308, they can adaptively adjust and engage according to the actual cross-sectional size of the fastening bolt 402.

[0034] Following this, as the movable adjusting block 308 moves up and down, a limiting vertical rod 3081 is also provided at the lower end of the movable adjusting block 308. The limiting vertical rod 3081 forms a nested lifting motion within the fixed sleeve rod 3051. When the driven gear disc 305 rotates, it drives the fixed sleeve rod 3051 to rotate synchronously, allowing the movable adjusting block 308 to rotate circumferentially at the upper end of the reciprocating screw 306. This is to cooperate with the rotational and lifting forces generated when the fastening bolt 402 and the parallel groove clamp 4 are threaded together, thereby making the threaded connection between the fastening bolt 402 and the parallel groove clamp 4 more secure and stable. Under the action of the second worm gear 301, it can drive the adjusting box 3 and the parallel groove clamp 4 to perform tilt angle adjustment. Under the action of the first worm gear 103, the adjusting box 3 and the parallel groove clamp 4 can perform circumferential rotation adjustment, which is convenient for fastening and clamping high-voltage transmission lines at different angles and positions.

[0035] Among them, the upper front and rear sides of the adjustment box 3 are fixedly installed with fixed guide plates 302, which facilitates positioning and guidance when the parallel groove clamp 4 is disassembled later.

[0036] Example 3 This embodiment is derived based on Embodiment 1 and Embodiment 2. Please refer to [link / reference]. Figure 1 , Figure 2 and Figure 6 In this invention, a technical solution is provided: the first positioning wiring block 404 and the second positioning wiring block 405 are arranged symmetrically front and back at the upper end of the movable horizontal plate 403; A fixed connector 406 connected to the parallel groove clamp 4 is provided directly above the first positioning connector 404, and the first positioning connector 404 and the fixed connector 406 are vertically corresponding. A wiring groove 407 is provided on the inner side of the right end of the parallel groove clamp 4 for cable passage.

[0037] Specifically, in conjunction with Embodiments 1 and 2, before use, the spare cable is passed through the wiring groove 407 and inserted into the inner right side of the parallel groove clamp 4, so that the upper end of the spare cable contacts the groove opening inside the wiring groove 407. The fixed wiring blocks 406 symmetrically arranged on the inner upper side of the parallel groove clamp 4 are then hung on the high-voltage transmission line. When the fastening bolt 402 rotates, the movable horizontal plate 403 can move stably up and down within the parallel groove clamp 4, thereby facilitating the movement of the first fixed wiring blocks symmetrically arranged on the upper side of the movable horizontal plate 403. The first positioning connector 404 and the second positioning connector 405 move synchronously. At this time, the first positioning connector 404 moves upward and contacts the lower surface of the high-voltage transmission line, and cooperates with the fixed connector 406 to achieve the function of fastening and clamping. At the same time, the upward movement of the second positioning connector 405 can position and clamp the spare cable. Finally, the entire fixed base plate 1 is removed, so that the parallel groove clamp 4 can clamp the high-voltage transmission line and the spare cable, or the high-voltage transmission line can be fastened and clamped by the parallel groove clamp 4 alone.

[0038] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
