Description

Technical Field

[0001] This invention relates to a combination device and method for replacing or resetting the ground potential of a conductor vibration damper, belonging to the technical field of conductor vibration dampers. Background Technology

[0002] Most vibration dampers on overhead transmission line conductors are bolt-type. These dampers are easily damaged and displaced due to various weather conditions and long-term line operation. Once damaged or displaced, they lose their vibration damping function and may damage the conductors, seriously threatening the safe operation of the transmission line. Currently, vibration damper replacement and recovery work often involves power outages or equipotential live-line work. However, power outages are subject to various constraints and cannot be approved in a timely manner. Equipotential live-line work has high safety requirements, making it difficult to perform in some situations, necessitating power outages, which significantly reduces power supply reliability. If replacing or resetting damaged bolt-type vibration dampers under equipotential conditions, the distance between the damper and the tension or suspension clamp varies depending on voltage level, line span, and other conditions. Workers operating under equipotential conditions must also meet live-line work distance requirements. Without specialized tools, replacing or resetting vibration dampers under equipotential conditions is extremely difficult and inconvenient. Summary of the Invention

[0003] The purpose of this invention is to provide a combination device and method for replacing or resetting the ground potential of a conductor vibration damper. While meeting the safety distance requirements between personnel and live parts for live-line work, it achieves the purpose of replacing or resetting the conductor vibration damper without power interruption or manual wiring, thus avoiding power outages, improving power supply reliability, and ensuring that the overall operation process is safe, efficient, and highly applicable. This invention solves the aforementioned technical problems existing in the prior art.

[0004] The technical solution of this invention is: A live-line replacement or reset device for a conductor vibration damper includes a bolt tightening device, a screw removal or insertion device, and a vibration damper removal or installation device. The bolt tightening device, used to loosen or tighten the vibration damper nut while energized, includes a sleeve, an adapter, a commutator, a connecting rod, and a push-pull rod. One end of the sleeve matches the vibration damper nut, and the other end of the sleeve has a groove and is connected to the commutator via the adapter. One end of the connecting rod is hinged to the commutator, and the other end is connected to the push-pull rod. The adapter consists of a sleeve connector, a gate post, and an anti-detachment slot. A spring ball on the sleeve connector is pressed into the groove inside the sleeve to hold it in place. The gate post and the anti-detachment slot are connected via a rotating shaft. The anti-detachment slot can rotate 180° around the rotating shaft within the gate post to change direction. The anti-detachment slot has a square hollow groove inside, with a recess on each of its four sides. The screw removal or insertion device is used to remove or insert the screw of the conductor vibration damper while it is energized. It includes a suction device and a magnetic pull rod. The suction device includes a housing and a first rotary joint. The housing is cylindrical, with a hollow groove at one end containing a magnet. The magnet has a suction head, which matches the vibration damper screw on the bolt-type vibration damper. The other end of the cylinder has a first rotary joint, which is directly or indirectly connected to the magnetic pull rod. The magnetic pull rod includes a second rotary joint, an insulating tube, and a threaded joint. The second rotary joint and the threaded joint are fixed to both ends of the insulating tube by their respective fixing pins. The first and second rotary joints have the same structure, both being annularly arranged toothed structures that match each other and are connected by bolts. The vibration damper removal or installation device is used to remove or install the conductor vibration damper while it is energized. It includes a hanging plate, an adjusting plate, and insulating hooks. The top of the hanging plate is provided with a rope hole, and the bottom is connected to the adjusting plate. Insulating hooks are provided on both sides of the adjusting plate. The distance between the two insulating hooks is greater than the width of the clamping plate on the conductor vibration damper and less than the minimum distance between the two hammers on the conductor vibration damper. The two insulating hooks hook and lift the steel strand of the conductor vibration damper. The commutator consists of an adapter connector, a second gatepost, and a second rotating shaft.

[0008] The toothed structure of rotary joint one and rotary joint two consists of a cylindrical body with slots and multiple trapezoidal bosses on its sides. Gaps are left between the trapezoidal bosses to form the toothed structure, and the slots facilitate bolt assembly. The toothed structures mesh together, and bolts are passed through the central slots for connection, thus changing the direction of rotation.

[0009] The threaded joint of the magnetic pull rod is connected to the insulated operating link, extending the rotating arm.

[0010] The rotary joint one of the suction rod and the rotary joint two of the magnetic pull rod are indirectly connected via a portal bend to accommodate different rotation angles. The portal bend includes a portal rod, a short rotary joint, and a long rotary joint. The two ends of the portal rod are connected to the short and long rotary joints respectively. The short rotary joint is connected to the rotary joint one on the suction rod via bolt one, and the long rotary joint is connected to the rotary joint two on the magnetic pull rod via bolt two. In actual working conditions, the anti-vibration hammer screw may be installed inside or outside the conductor. If the anti-vibration hammer screw is on the outside of the conductor, the portal bend connects the rotary joint one of the suction rod and the rotary joint two of the magnetic pull rod for easier operation.

[0011] The short rod rotary joint, long rod rotary joint, rotary joint one, and rotary joint two have the same structure and can all be matched with each other.

Insulating hooks 18 are provided on both sides of the adjusting plate 17. The distance between the two insulating hooks 18 is greater than the width of the clamping plate 21 on the conductor vibration damper 1 and less than the minimum distance between the two hammer bodies on the conductor vibration damper 1. The two insulating hooks 18 hook and lift the steel strand 22 of the conductor vibration damper 1. The commutator 6 consists of an adapter connector 6-1, a second gatepost 6-6, and a second rotating shaft 6-7. A steel ball 6-2 is provided on one side of the square column of the adapter connector 6-1, which matches the internal groove of the anti-disengagement slot 5-5 of the adapter 5, and can lock the adapter connector 6-1 in any direction according to the different operating angles of the personnel.

[0022] The connecting rod 7 consists of a locking pin 7-1, a rotating body 7-3, and an extension arm 7-5. The locking pin 7-1 and the rotating body 7-3 at one end of the extension arm 7-5 are connected by a rotating shaft 7-2.

One end of the operating rod connector 9-3 is connected to the connecting plate 9-1, and the other end is connected to the insulated operating rod 14.

[0024] The suction rod device has a cylindrical magnet installed inside its housing. Its function is to remove or insert the anti-vibration hammer screw by means of the magnetic attraction. The magnet is equipped with a suction head for protection to prevent damage to the magnet from impact at the moment of contact with the anti-vibration hammer screw. The housing and the rotary joint are welded together.

[0025] The toothed structure of rotary joint 11-4 and rotary joint 12-4 consists of a cylindrical body with slots 33 and multiple trapezoidal protrusions 34 on its sides. Gaps 35 are left between the trapezoidal protrusions, forming a toothed structure. The slots 33 facilitate bolt assembly. The toothed structures mesh together, and bolts are passed through the central slots 33 for connection, thus changing direction.

[0026] The threaded joint 12-3 of the magnetic pull rod 12 is connected to the insulated operating link 31, extending the rotating arm.

[0027] The rotary joint 11-4 of the suction rod 11 and the rotary joint 12-4 of the magnetic pull rod 12 are indirectly connected by a portal corner joint 13 to accommodate different rotation angles. The portal corner joint 13 includes a portal rod 13-2, a short rod rotary joint 13-1 and a long rod rotary joint 13-3.

[0028] The short rod rotary joint 13-1, long rod rotary joint 13-3, rotary joint one 11-4 and rotary joint two 12-4 have the same structure and can be matched with each other.

[0029] The lower part of the mounting plate 16 is provided with a boss, and the adjusting plate 17 is provided with a matching groove. The mounting plate 16 and the adjusting plate 17 are positioned by the boss matching the groove and are connected by locking screws.

[0030] The adjustment plate 17 and the insulating hook 18 are connected by a locking screw.

[0031] The rope hole 15 of the hanging plate 16 is matched with the insulating rope 20. The insulating rope can pass through the rope hole 15. Its function is to allow the operator to apply force to the hanging plate through the insulating rope, so as to move and raise the conductor vibration damper.

[0032] The length of the adjustment plate can be adjusted or replaced by unscrewing the locking screws to suit various models of conductor vibration dampers, depending on the actual situation.

[0033] The two insulating hooks are used to hook the steel strands in the middle of both ends of the conductor vibration damper, thereby supporting the entire conductor vibration damper.

[0034] A method for replacing or resetting the ground potential of a vibration damper for a transmission line conductor while it is energized, comprising: Remove the conductor vibration damper: Loosen the vibration damper nut using the bolt tightening device and remove the vibration damper nut; remove the vibration damper screw using the screw removal or insertion device; remove the conductor vibration damper clamp and conductor vibration damper under ground potential energized environment using the vibration damper removal or installation device. Replace or reset the conductor vibration damper: Reset the conductor vibration damper using the vibration damper removal or installation device; insert the vibration damper screw using the screw removal or insertion device; tighten the vibration damper nut using the bolt tightening device to complete the installation of the conductor vibration damper in an environment with ground potential.

[0035] The specific operating steps include the following: ① The operator stands at a suitable position on the tower, assembles the bolt tightening device, adjusts the angle of the adapter and commutator, connects the insulating operating rod to the operating rod connector, operates the device through the insulating operating rod, puts the sleeve on the bolt-type anti-vibration hammer nut that needs to be replaced or reset, and pushes or pulls the insulating operating rod back and forth to loosen the anti-vibration hammer nut on the anti-vibration hammer until the anti-vibration hammer nut falls off and is retracted together with the device; ②Assemble the screw removal or insertion device by connecting the threaded joint on the insulated operating link and the magnetic pull rod. Operate the device through the insulated operating link and slowly bring the suction rod of the device close to the anti-vibration hammer screw. Under the attraction of the magnet, the anti-vibration hammer screw will come out of the screw hole of the anti-vibration hammer until it is finally detached and retracted together with the device. ③ To remove the vibration damper or assemble the installation device, pass one end of the insulating rope through the rope hole of the device and tie a knot, and pass the other end through the pulley. Place the pulley on the conductor or ground wire above the vibration damper, pull the insulating rope to drive the device to hook the steel strand between the two ends of the conductor vibration damper, rotate the angle until the vibration damper is detached from the conductor, and then pull the pulley and the device back. Finally, if the safe distance is met, retrieve the damaged vibration damper, or place the displaced vibration damper back to the initial position and then retrieve the device. ④ If the damaged vibration damper is to be replaced, place the new vibration damper on the insulating hook, push the pulley to move slowly upwards to the installation position of the vibration damper, and after reaching the position, slowly loosen the insulating rope at the pulley end until the clamp of the vibration damper clamps the wire, and then take the device and pulley back together. ⑤ After replacing the vibration damper or placing the displaced vibration damper back to its initial position, the operator uses the screw removal or insertion device to attach the vibration damper screw to the suction rod device. The vibration damper screw is then pushed to the screw hole position and inserted through the insulated operating rod. The angle of contact between the suction rod device and the vibration damper screw should not be consistent with the direction of the screw hole. The insulated operating rod is pulled forcefully until the suction rod device and the vibration damper screw separate, and then the device is retracted. ⑥ Finally, use the bolt tightening device again. First, put the sleeve over the anti-vibration hammer nut. Operate the device through the insulated operating rod. After aligning the anti-vibration hammer nut in the sleeve with the anti-vibration hammer screw, push or pull the insulated operating rod back and forth to tighten the anti-vibration hammer nut until it is firmly tightened onto the anti-vibration hammer screw. Then, retract the device to finish the work.

[0036] Step 1: As Figure 1 and Figure 2The diagram shows the operation structure of the vibration damper nut 2 of the conductor vibration damper, which is loosened by using a bolt tightening device when it is inside or outside the conductor 3. The live-line worker stands at a suitable position on the pole, first selecting a suitable sleeve 4 according to the model of the vibration damper nut 2, and installing the sleeve connector 5-1 of the adapter 5 at the bottom of the sleeve 4. Then, pressure is applied to the pressing column 6-3 of the commutator 6, causing the steel ball 6-2 to indent. Depending on the required operating angle, the steel ball 6-2 on the adapter connector 6-1 is pushed into the groove on the appropriate surface of the anti-disengagement groove 5-5. When the steel ball 6-2 reaches the groove, the pressure on the pressing column 6-3 is released, and the anti-disengagement groove 5-5 will firmly lock the adapter connector 6-1. The connecting rod 7 is connected to the gate post 6-6 of the commutator 6 via the rotating shaft 6-7 inserted into the rotating body 7-3. For ease of operation, the connecting rod 7 and the commutator 6 can be rotated to a suitable angle via the rotating shaft 6-7. The hole on the connecting plate 9-1 of the push-pull rod 9 and the last connecting hole of the extension arm 7-5 on the connecting rod 7 are connected by the bolt 36. Loosening the bolt 36 appropriately allows the extension arm 7-5 to rotate back and forth in the middle of the clamping table 9-2. Finally, connect the insulating operating rod 14 to the operating rod connector 9-3, and further adjust the angles of the adapter 5 and the commutator 6. The operator operates the device through the insulating operating rod 14. Put the sleeve 4 on the anti-vibration hammer nut 2, and push or pull the insulating operating rod 14 to loosen or tighten the anti-vibration hammer nut 2. When the extension arm 7-5 is rotated to one end of the clamping table 9-2, move the insulating operating rod 14 to move the sleeve 4 of the device away from the anti-vibration hammer nut 2 by an appropriate distance. Push or pull the insulating operating rod to rotate the extension arm 7-5 to the other end of the clamping table 9-2, and then put the sleeve 4 on the anti-vibration hammer nut 2. Push or pull the insulating operating rod 14, and repeat this operation to loosen the anti-vibration hammer nut 2 until the anti-vibration hammer nut falls off and is retracted together with the device.

[0037] Step 2: As Figure 8 and Figure 9The diagrams show the operation structure for removing the anti-vibration hammer screw 10 from the inside and outside of the conductor 3 using a screw removal or insertion device. The live-line worker first selects a suitable angle according to the operational needs, engages the rotary joint 11-4 on the suction rod 11 and the rotary joint 12-4 on the magnetic pull rod 12, passes the bolt 8 through the slot between the two rotary joints and tightens it securely. Then, the threaded joint 12-3 on the magnetic pull rod 12 is connected to the insulated operating rod 31. When removing the anti-vibration hammer screw 10, the operator uses the insulated operating linkage 31 to slowly move the suction device 11 of the device closer to the anti-vibration hammer screw 10. The housing 11-1 of the suction device 11 contains a magnet 11-3. Under the attraction of the magnet 11-3, the anti-vibration hammer screw 10 will suddenly enter the housing 11-1 of the suction device 11 just before contact. The magnet 11-3 has a suction head 11-2 for anti-collision protection. Then, the angle of contact between the suction device 11 and the anti-vibration hammer screw 10 is adjusted, and force is applied in the direction of screw removal. The conductor anti-vibration hammer 1 itself is relatively heavy and is less affected by the attraction of the magnet 11-3, while the anti-vibration hammer screw 10 is relatively light. Under the attraction, it will come out of the screw hole of the conductor anti-vibration hammer 1 until it is detached and retracted together with the device. When the conductor vibration damper screw 10 is on the outside of the conductor 3, a gate-type corner device 13 needs to be connected between the suction rod 11 and the magnetic pull rod 12 of the device. The operation method is the same as when it is on the inside of the conductor.

[0038] Step 3: As Figure 14 The diagram shows the operation structure for removing the conductor vibration damper 1 using the vibration damper installation or removal device. The operator selects a suitable adjustment plate 17 based on the model of the conductor vibration damper 1 and tightens it with locking screws 19, hanging plates 16, and insulating hooks 18. One end of the insulating rope 20 is passed through the rope hole 15 of the device and tied in a knot. The other end is passed through the pulley, and the pulley is placed on the conductor or ground wire above the conductor vibration damper 1. The insulating rope 20 is pulled at the pulley end, moving the device until it reaches directly above the conductor vibration damper 1. The insulating rope 20 is then lowered slightly, and the position is adjusted until the insulating hook 18 hooks the steel strand between the two ends of the conductor vibration damper 1. At this point, the insulating rope 20 is pulled upwards slightly, causing the device and the clamping plate 21 of the conductor vibration damper 1 to slowly rotate at a certain angle until the clamping plate 21 detaches from the conductor 3. The insulating rope 20 is then pulled to a suitable position, and the pulley and the device are pulled back. Finally, the damaged vibration damper is retrieved while maintaining a safe distance.

[0039] Step 4: The operator places the new vibration damper on the insulating hook 18 in the vibration damper installation or removal device. Another operator holds the insulating rope 20 and pushes the pulley to slowly move it upwards towards the vibration damper installation position. After reaching the position, slowly release the insulating rope 20. Since there are no bolts on the conductor vibration damper 1 at this time, the clamp 21 can rotate. Adjust the opening angle of the clamp 21 by pulling the insulating rope 20 back and forth until the conductor 3 can enter the clamp 21. Then, remove the vibration damper installation or removal device and the pulley together.

[0040] Step 5: The operator uses the screw removal or insertion device again to insert the anti-vibration hammer screw 10. First, the anti-vibration hammer screw is attracted to the suction rod 11 of the device. Then, the anti-vibration hammer screw 10 is slowly pushed to the screw hole position of the conductor anti-vibration hammer 1 through the insulated operating rod 31. The angle of the anti-vibration hammer screw 10 is adjusted and inserted in the direction of the screw hole. Finally, the angle of contact between the suction rod 11 and the anti-vibration hammer screw 10 is not consistent with the direction of the screw hole. The operator pulls the insulated operating rod 31 forcefully. At this time, the anti-vibration hammer screw is firmly stuck in the screw hole of the conductor anti-vibration hammer 1. When the force applied by the operator is greater than the attraction force of the magnet 11-3, the suction rod 11 and the anti-vibration hammer screw 10 separate, and the screw removal or insertion device is retracted.

[0041] Step 6: Finally, tighten the vibration damper nut again using the bolt tightening device. First, put the sleeve over the vibration damper nut. Operate the device using the insulated operating rod, in the same way as in Step 1. Align the vibration damper nut in the sleeve with the vibration damper screw, and push or pull the insulated operating rod back and forth to tighten the vibration damper nut until it is firmly tightened onto the vibration damper screw. Then, retract the bolt tightening device to complete the work.

[0042] Step 1: The operation method is the same as Step 1 in Example 1. Use the bolt tightening device to loosen the vibration damper nut of the displaced conductor vibration damper.

[0043] Step 2: The operation method is the same as in Step 2 of Example 1. Use the screw removal or insertion device to remove the anti-vibration hammer screw on the conductor anti-vibration hammer.

[0044] Step 3: The operation method is basically the same as Step 3 in Example 1. Use the anti-vibration hammer installation or removal device to remove the anti-vibration hammer from its current position. Do not retract it at this time.

[0045] Step 4: The operator grasps the insulating rope 20 and pushes the pulley to slowly move it above the position where the vibration damper will be reinstalled. After reaching the position, the operator slowly releases the insulating rope 20. Since there are no bolts on the conductor vibration damper 1 at this time, the clamp 21 can rotate. The operator adjusts the opening angle of the clamp 21 by pulling the insulating rope 20 back and forth until the conductor 3 can enter the clamp 21. Then, the vibration damper installation or removal device and the pulley are taken back together.

[0046] Step 5: The operation method is the same as in Step 5 of Example 1. Use the screw removal or insertion device to re-insert the anti-vibration hammer screw on the conductor anti-vibration hammer.

[0047] Step 6: The operation method is the same as in Step 6 of Example 1. Use the bolt tightening device to tighten the anti-vibration hammer nut until it is secure. Then retract the device and the work is finished.
