Description

Technical Field

[0001] This invention relates to the field of cable maintenance technology, specifically to a device and method for securing the upper lead of a switch and placing it upright in a bottle for live-line work. Background Technology

[0002] In live-line emergency repairs, if the pin insulator (vertical insulator) used to fix the top lead of the drop-out fuse, along with its own tied top lead, becomes loose at the crossarm connection point, it will create a line defect that is difficult to handle. It is easy to induce phase-to-phase short-circuit faults and poses a great risk of equipment damage and personal safety. It is a typical defect that is difficult to handle efficiently in live-line emergency repairs.

[0003] When handling detached insulated cylinders with live wires using traditional methods, one operator cannot directly work with insulated gloves because the detached cylinder and its fixed upper lead are at different potentials. Two electricians working inside the bucket are required to work with two insulated bucket trucks. One operator uses an insulated locking rod to lock the cylinder, while the other operator uses another insulated bucket truck to secure the cylinder to the crossarm. This method requires two people, is time-consuming and complex, and the angle of force application is very inconvenient when fixing the detached cylinder, which greatly increases the labor intensity of the workers inside the bucket. Summary of the Invention

[0004] This invention provides a device and method for securing the upper lead wire of a switch for live-line work, in order to solve the problem that the prior art requires two people to work together when repairing a loosened bottle, which is inconvenient, time-consuming and labor-intensive.

[0007] Furthermore, the first transmission component includes a first transmission shaft and a first rotating sleeve. The first main rod is a hollow structure. Both the first transmission shaft and the first rotating sleeve are disposed inside the first main rod and are coaxial with the first main rod. In the radial direction of the first main rod, the first rotating sleeve is located between the first main rod and the first transmission shaft. The first rotating sleeve can rotate relative to the first main rod and is restricted from moving by the first main rod. The first rotating sleeve is screw-fitted with the first transmission shaft. The second gripper is fixedly installed on the first transmission shaft and is located at the end of the first transmission shaft close to the first gripper along the horizontal central axis of the first main rod.

[0008] Furthermore, one end of the first rotating sleeve, located away from the first gripper along the horizontal central axis of the first main rod, extends out of the first main rod, and a first handle is provided at the end of the first rotating sleeve extending out of the first main rod.

[0009] Furthermore, a first limiting ring is coaxially arranged on the inner peripheral wall of the first main rod, and a first rotating groove is formed on the outer peripheral wall of the first rotating sleeve for rotating cooperation with the first limiting ring.

[0010] Furthermore, a pressure plate is provided on the first gripper, the pressure plate is located above the first gripper, and a spring piece is fixedly provided on the pressure plate, and in the vertical direction, the spring piece is located between the pressure plate and the first gripper.

[0011] Furthermore, the third insulating rod includes a second main rod, a first top block, a second top block, and a second transmission component. The second main rod is arranged in a horizontal direction. The first top block is fixedly installed on the second main rod, and the second top block is slidably installed on the second main rod and located on the same side as the first top block. The second transmission component is installed on the second main rod and can cause the second top block to move along the horizontal central axis of the second main rod, moving closer to or away from the first top block.

[0012] Furthermore, both the first and second insulating rods are provided with locking sleeves, and the locking sleeve on the first insulating rod is installed on the third insulating rod through a first buckle.

The locking sleeve on the second insulating rod is rotatably installed on the first insulating rod through a second buckle. The locking sleeve on the second insulating rod can allow or restrict the second insulating rod to move in the horizontal direction relative to the first insulating rod.

[0013] Furthermore, the locking sleeve on the first insulating rod includes a sliding sleeve, a first elastic element, and a pressure handle.

[0018] S40, the first insulating rod moves up and down relative to the third insulating rod. The movement of the first insulating rod will drive the bottle to move through the second insulating rod, adjusting its position in the vertical direction.

[0019] S50, fix the upright bottle to the crossbar.

[0020] The beneficial effects of this invention are as follows: The device for securing the upper lead of a switch and the upright bottle for live-line work uses a main fixing mechanism and an auxiliary fixing mechanism in combination. The third insulating rod of the auxiliary fixing mechanism is first fixed to the crossarm to form a stable support, and a second insulating rod that can rotate and move horizontally is used to horizontally position the upright bottle, while a first insulating rod that can be adjusted vertically is used to vertically position the upright bottle. This allows the upright bottle to be easily fixed to the crossarm. Only one operator is needed to handle the loosening of the upright bottle, which greatly reduces the investment of manpower and supporting resources for live-line work and lowers the construction cost of live-line emergency repair of distribution networks. In addition, the device can drive the upright bottle to be adjusted at multiple angles, eliminating the need to laboriously find the force application angle and eliminating the problems of limited force application angle and high labor intensity in traditional operations, thus improving the convenience of operation.

[0021] Furthermore, by setting a spring clip, when the bottle is clamped by the second insulating rod, the lead wire on the bottle will also squeeze the spring clip, and the spring clip will press the lead wire tightly, providing auxiliary fixation between the bottle and the lead wire, preventing the lead wire from becoming loose when the bottle is being repaired.

Detailed Implementation

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0035] An embodiment of the device for securing the upper lead of a switch for live-line work according to the present invention is as follows: Figures 1 to 10 As shown.

[0036] A device for securing a switch upper lead insulator for live-line work is provided. The insulator 100 is inserted into a through hole on a crossarm 200, and the insulator 100 is locked to the crossarm 200 with a nut. An upper lead wire 110 is fixed to the upper end of the insulator 100, and a screw 120 for inserting into the through hole is provided at the lower end of the insulator 100. The nut is located below the crossarm 200 and screw-fits the screw 120. The crossarm 200 is an angle iron horizontally fixed to the top of a utility pole to support overhead power lines. A device for securing the lead wire of a switch for live-line work and standing a bottle 100 includes a main fixing mechanism 300 and an auxiliary fixing mechanism 400. The main fixing mechanism 300 includes a first insulating rod 310 and a second insulating rod 320. The first insulating rod 310 is arranged in a vertical direction, and the second insulating rod 320 is arranged in a horizontal direction and can clamp the bottle 100. The second insulating rod 320 is detachably installed on the first insulating rod 310, rotates with the first insulating rod 310, and can move horizontally relative to the first insulating rod 310.

[0037] The auxiliary fixing mechanism 400 includes a third insulating rod 410, which is horizontally positioned and can be mounted on the crossarm 200. A first insulating rod 310 is detachably mounted on the third insulating rod 410 and can move up and down relative to the third insulating rod 410. The lengths of the first insulating rod 310, the second insulating rod 320, and the third insulating rod 410 all conform to the safe distance lengths specified in the live-line operation procedures. By utilizing reliable operating distances, dangers such as phase-to-phase short circuits are prevented, effectively ensuring the safety of operators.

[0038] In this embodiment, by setting up a main fixing mechanism 300 and an auxiliary fixing mechanism 400 in cooperation, the operator is transported to the location that needs emergency repair by an insulated bucket truck during operation. The operator first fixes the third insulating rod 410 to the crossarm 200, then uses the second insulating rod 320 to clamp the loose bottle 100, then installs the first insulating rod 310 on the third insulating rod 410, and finally installs the second insulating rod 320 on the first insulating rod 310. After all installation is completed, by rotating and moving the second insulating rod 320 relative to the first insulating rod 310, the vertical bottle 100 is adjusted to its horizontal position so that it can find the through hole on the crossarm 200. By moving the first insulating rod 310 up and down relative to the third insulating rod 410, the second insulating rod 320 is moved synchronously, changing the vertical position of the vertical bottle 100 relative to the crossarm 200 so that the screw 120 of the vertical bottle 100 can be inserted into the through hole. Finally, the nut is tightened onto the screw 120 of the vertical bottle 100 using the external insulating auxiliary rod, locking the vertical bottle 100 to the crossarm 200, thus completing the process of removing the vertical bottle 100 from the crossarm.

[0039] In this embodiment, the third insulating rod 410 of the auxiliary fixing mechanism 400 is first fixed to the crossarm 200 to form a stable support. It is then used in conjunction with the second insulating rod 320, which can rotate and move horizontally, to horizontally position the upright bottle 100, and the first insulating rod 310, which can be vertically adjusted, to vertically position the upright bottle 100. This allows the upright bottle 100 to be easily fixed to the crossarm 200. Only one operator is needed to handle the loosening of the upright bottle 100, which greatly reduces the investment of manpower and supporting resources for live-line work and lowers the construction cost of live-line emergency repair of the distribution network. In addition, the device can drive the upright bottle 100 to be adjusted at multiple angles, eliminating the need to laboriously find the force application angle and eliminating the problems of limited force application angle and high labor intensity in traditional operations, thus improving the ease of operation.

[0040] In a further embodiment, the second insulating rod 320 includes a first main rod 321, a first gripper 322, a second gripper 323, and a first transmission member. The first main rod 321 is arranged horizontally. The first gripper 322 is fixedly mounted on the first main rod 321 by a mounting sleeve. The second gripper 323 is slidably mounted on the first main rod 321 and is located on the same side as the first gripper 322. A first clamping space is defined between the first gripper 322 and the second gripper 323. The first transmission member is mounted on the first main rod 321 and can cause the second gripper 323 to move along the horizontal central axis of the first main rod 321, moving closer to or away from the first gripper 322.

[0041] The first transmission component includes a first transmission shaft 324 and a first rotating sleeve 325. The first main rod 321 is a hollow structure. Both the first transmission shaft 324 and the first rotating sleeve 325 are disposed inside the first main rod 321 and are coaxial with the first main rod 321. In the radial direction of the first main rod 321, the first rotating sleeve 325 is located between the first main rod 321 and the first transmission shaft 324. The first rotating sleeve 325 can rotate relative to the first main rod 321 and is restricted from moving by the first main rod 321. The first rotating sleeve 325 is screwed to the first transmission shaft 324. The second gripper 323 is fixedly installed on the first transmission shaft 324 and is located at the end of the first transmission shaft 324 close to the first gripper 322 along the horizontal central axis of the first main rod 321.

[0042] Specifically, one end of the first rotating sleeve 325 extends out of the first main rod 321 along the horizontal central axis of the first main rod 321, away from the first gripper 322, and a first handle 326 is provided at the end of the first rotating sleeve 325 extending out of the first main rod 321.

[0043] A first limiting ring 327 is coaxially arranged on the inner peripheral wall of the first main rod 321, and a first rotating groove is provided on the outer peripheral wall of the first rotating sleeve 325 for rotating cooperation with the first limiting ring 327, thereby enabling the first rotating sleeve 325 to rotate relative to the first main rod 321, and the first rotating sleeve 325 is restricted by the first main rod 321 to not move.

[0044] Furthermore, a pressure plate 328 is fixedly disposed on the first gripper 322, the pressure plate 328 is located above the first gripper 322, and a spring piece 329 is fixedly disposed on the pressure plate 328, and in the vertical direction, the spring piece 329 is located between the pressure plate 328 and the first gripper 322.

[0045] Furthermore, there are two spring clips 329, which are referred to as the first spring clip and the second spring clip respectively. The first spring clip has an arc-shaped structure, and the second spring clip has a W-shaped structure. The first spring clip is located on the side of the second spring clip that is close to the first gripper 322 in the vertical direction.

[0046] When the second insulating rod 320 is needed to clamp the upright bottle 100, the operator holds one end of the first handle 326 and swings the entire second insulating rod 320 in a vertical direction, so that the upright bottle 100 is in the first clamping space defined by the first clamping claw 322 and the second clamping claw 323, thus initially positioning the upright bottle 100. The lead wire 110 on the upright bottle 100 will also squeeze the spring piece 329, and the spring piece 329 will press the lead wire 110 tightly, thus providing auxiliary fixation between the upright bottle 100 and the lead wire 110, preventing the lead wire 110 from becoming loose when the upright bottle 100 is being repaired. The operator then rotates the first handle 326. The rotation of the first handle 326 will drive the first rotating sleeve 325 to rotate. The first rotating sleeve 325 will rotate relative to the first main rod 321. Since the first rotating sleeve 325 is screwed with the first drive shaft 324, the rotation of the first rotating sleeve 325 will cause the first drive shaft 324 to move. The movement of the first drive shaft 324 will drive the second gripper 323 to move closer to the first gripper 322 and clamp the bottle 100.

[0047] In a further embodiment, the third insulating rod 410 includes a second main rod 411, a first top block 412, a second top block 413, and a second transmission member. The second main rod 411 is arranged horizontally. The first top block 412 is fixedly mounted on the second main rod 411, and the second top block 413 is slidably mounted on the second main rod 411 and located on the same side as the first top block 412. A first pressing space is defined between the first top block 412 and the second top block 413. The second transmission member is mounted on the second main rod 411 and can cause the second top block 413 to move along the horizontal central axis of the second main rod 411, moving closer to or away from the first top block 412.

[0048] The second main rod 411 has a hollow structure, and the structure of the second transmission component is the same as that of the first transmission component. The second transmission component includes a second transmission shaft 414 and a second rotating sleeve. Both the second transmission shaft 414 and the second rotating sleeve are disposed inside the second main rod 411 and are coaxial with the second main rod 411. In the radial direction of the second main rod 411, the second rotating sleeve is located between the second main rod 411 and the second transmission shaft 414. The second rotating sleeve can rotate relative to the second main rod 411 and is restricted in movement by the second main rod 411. The second rotating sleeve is screwed into the second transmission shaft 414. The second top block 413 is fixedly installed on the second transmission shaft 414 and is located at the end of the second transmission shaft 414 near the first top block 412 along the horizontal central axis of the second main rod 411.

[0049] Specifically, one end of the second rotating sleeve extending away from the first top block 412 along the horizontal central axis of the second main rod 411 extends out of the second main rod 411, and a second handle is provided at the end of the second rotating sleeve extending out of the second main rod 411.

[0050] The second main rod 411 has a second limiting ring coaxially arranged on its inner peripheral wall, and the second rotating sleeve has a second rotating groove for rotating with the second limiting ring on its outer peripheral wall, so that the second rotating sleeve can rotate relative to the second main rod 411, and the second rotating sleeve is restricted by the second main rod 411 to not move.

[0051] In use, the operator holds one end of the second handle and moves the entire third insulating rod 410 from top to bottom, so that the crossarm 200 is initially positioned within the first pressing space defined by the first top block 412 and the second top block 413. Then, the operator rotates the second handle, which will drive the second rotating sleeve to rotate. The second rotating sleeve will rotate relative to the second main rod 411. Since the second rotating sleeve is screwed with the second transmission shaft 414, the rotation of the second rotating sleeve will cause the second transmission shaft 414 to move. The movement of the second transmission shaft 414 will drive the second top block 413 to move closer to the first top block 412 and fix it to the crossarm 200.

[0052] In a further embodiment, both the first insulating rod 310 and the second insulating rod 320 are provided with locking sleeves 420. The locking sleeve 420 on the first insulating rod 310 is mounted on the third insulating rod 410 via a first snap fastener 430. The locking sleeve 420 on the first insulating rod 310 allows or restricts the first insulating rod 310 to move vertically relative to the third insulating rod 410. The locking sleeve 420 on the second insulating rod 320 is rotatably mounted on the first insulating rod 310 via a second snap fastener 440. The locking sleeve 420 on the second insulating rod 320 allows or restricts the second insulating rod 320 to move horizontally relative to the first insulating rod 310.

[0053] Taking the locking sleeve 420 on the first insulating rod 310 as an example, the locking sleeve 420 includes a sliding sleeve 421, a first elastic element 422, and a pressure handle 423. The sliding sleeve 421 is slidably installed on the first insulating rod 310, coaxial with the first insulating rod 310, and engages with the keyway of the first insulating rod 310. Multiple locking grooves 330 are sequentially arranged on the first insulating rod 310 along its axial direction. The pressure handle 423 is rotatably installed on the sliding sleeve 421 through a rotating shaft and is connected to the sliding sleeve 421 through the first elastic element 422. The first elastic element 422 is arranged along the radial direction of the sliding sleeve 421 and is a compression spring. The pressure handle 423 can engage with any locking groove 330.

[0054] The structure of the locking sleeve 420 on the second insulating rod 320 is the same as that on the first insulating rod 310, and multiple locking slots 330 are also provided on the first main rod 321 of the second insulating rod 320.

[0055] The first buckle 430 includes a first buckle body and a second buckle body, both of which are annular open structures and are fixedly connected, specifically by welding. The first buckle body is coaxial with the first insulating rod 310 and locked to the locking sleeve 420 on the first insulating rod 310 by bolts. The second buckle body is coaxial with the third insulating rod 410 and locked to the third insulating rod 410 by bolts. Similar to the first buckle 430, the second buckle 440 includes a third buckle body and a fourth buckle body, both of which are annular and fixedly connected, and are integrally formed. The third buckle body is coaxial with the first insulating rod 310 and rotatably mounted on the first insulating rod 310 via a bearing 441, and the first insulating rod 310 has a protrusion for receiving the bearing 441. The fourth buckle body is coaxial with the second insulating rod 320 and locked to the locking sleeve 420 on the second insulating rod 320 by bolts.

[0056] When the second insulating rod 320 needs to move horizontally relative to the first insulating rod 310, the pressure handle 423 of the locking sleeve 420 on the second insulating rod 320 can be pressed, and the first elastic element 422 can be compressed, so that the pressure handle 423 and the locking groove 330 engaged with it can be disengaged. Then the second insulating rod 320 can move horizontally. By rotating the second insulating rod 320 relative to the first insulating rod 310, the upright bottle 100 can be adjusted to its horizontal position, so that the upright bottle 100 can find the through hole on the crossarm 200. After moving, the pressure handle 423 can be released, so that the pressure handle 423 can be engaged in other locking grooves 330 to lock the first insulating rod 310. When it is necessary to move the first insulating rod 310 up and down relative to the third insulating rod 410, press the lever 423 of the locking sleeve 420 on the first insulating rod 310 and compress the first elastic element 422, so that the lever 423 and the locking groove 330 engaged with it are disengaged. Then the first insulating rod 310 can move up and down, and drive the second insulating rod 320 to move up and down, changing the position of the upright bottle 100 relative to the crossarm 200 in the vertical direction, so that the screw 120 of the upright bottle 100 can extend into the through hole. After the movement, release the lever 423 so that the lever 423 is engaged in other locking grooves 330 to lock the first insulating rod 310.

[0057] Based on the above embodiments, the specific working process is as follows:

[0058] During operation, the operator is transported to the location requiring emergency repair via an insulated bucket truck. Then, the operator holds one end of the second handle and moves the entire third insulating rod 410 from top to bottom, so that the crossarm 200 is initially positioned within the first pressing space defined by the first top block 412 and the second top block 413. After that, the operator rotates the second handle, which will cause the second rotating sleeve to rotate. The second rotating sleeve will rotate relative to the second main rod 411. Since the second rotating sleeve is screwed with the second drive shaft 414, the rotation of the second rotating sleeve will cause the second drive shaft 414 to move. The movement of the second drive shaft 414 will cause the second top block 413 to move closer to the first top block 412, thus fixing the third insulating rod 410 onto the crossarm 200.

[0059] Then, the second insulating rod 320 is used to clamp the loose bottle 100. The specific operation is as follows: the operator holds one end of the first handle 326 and drives the entire second insulating rod 320 to swing in the vertical direction, so that the bottle 100 is in the first clamping space defined by the first clamping claw 322 and the second clamping claw 323, thus initially positioning the bottle 100. The lead wire 110 on the bottle 100 will also squeeze the spring piece 329, and the spring piece 329 will press the lead wire 110 tightly, thus providing auxiliary fixation between the bottle 100 and the lead wire 110, preventing the lead wire 110 from becoming loose when the bottle 100 is being repaired. The operator then rotates the first handle 326. The rotation of the first handle 326 will drive the first rotating sleeve 325 to rotate. The first rotating sleeve 325 will rotate relative to the first main rod 321. Since the first rotating sleeve 325 is screwed with the first drive shaft 324, the rotation of the first rotating sleeve 325 will cause the first drive shaft 324 to move. The movement of the first drive shaft 324 will drive the second gripper 323 to move closer to the first gripper 322 and clamp the bottle 100.

[0060] Next, the locking sleeve 420 on the first insulating rod 310 is connected to the third insulating rod 410 using the first buckle 430, and the locking sleeve 420 on the second insulating rod 320 is connected to the first insulating rod 310 using the second buckle 440. After all installations are completed, the pressure handle 423 on the locking sleeve 420 of the second insulating rod 320 is pressed, and the first elastic element 422 is compressed, causing the pressure handle 423 to disengage from the locking groove 330 it engages with. Then, the second insulating rod 320 can move horizontally. By rotating the second insulating rod 320 relative to the first insulating rod 310, the upright bottle 100 is adjusted to its horizontal position so that it can find the through hole on the crossarm 200. After moving, the pressure handle 423 is released, causing it to engage with other locking grooves 330 to lock the first insulating rod 310. Next, press the lever 423 of the locking sleeve 420 on the first insulating rod 310 and compress the first elastic element 422, causing the lever 423 to disengage from the locking groove 330 it engages with. Then, the first insulating rod 310 can move up and down, causing the second insulating rod 320 to move up and down as well, changing the vertical position of the upright bottle 100 relative to the crossarm 200. This allows the screw 120 of the upright bottle 100 to extend into the through hole. After movement, release the lever 423, causing it to engage with another locking groove 330, thus locking the first insulating rod 310. Finally, use the external insulating auxiliary rod to tighten the nut onto the screw 120 of the upright bottle 100, locking the upright bottle 100 to the crossarm 200, completing the process of loosening the upright bottle 100.

[0061] The present invention also provides a method for standing an insulator with the lead wire of a fastening switch for live-line work, which utilizes the above-mentioned device for standing an insulator with the lead wire of a fastening switch for live-line work, and includes the following steps:

[0062] S10, install the third insulating rod 410 on the crossarm 200, and use the second insulating rod 320 to clamp the loose bottle 100.

[0063] S20, the first insulating rod 310 is installed on the third insulating rod 410, and the second insulating rod 320 is installed on the first insulating rod 310.

[0064] S30, the second insulating rod 320 is rotated and moved relative to the first insulating rod 310, which drives the upright bottle 100 to adjust its position in the horizontal direction so that the upright bottle 100 can find the through hole on the crossarm 200.

[0065] S40, the first insulating rod 310 moves up and down relative to the third insulating rod 410. The movement of the first insulating rod 310 will drive the upright bottle 100 to move through the second insulating rod 320, adjusting its position in the vertical direction so that the screw 120 of the upright bottle 100 can extend into the through hole.

[0066] S50, tighten the nut onto the screw 120 of the upright bottle 100 to fix the upright bottle 100 to the crossbeam 200.
