Description

Technical Field

[0001] This invention provides a grounding ring replacement device and its working method, belonging to the field of grounding ring installation technology. Background Technology

[0002] Parallel groove clamps are used for connecting small- to medium-section aluminum stranded wires or steel-cored aluminum stranded wires, as well as steel stranded wires for overhead lightning protection, in positions where they are not under tension. They are also used for jumper connections on non-straight-line towers. In power engineering, these connecting wires are primarily used for power line projects. The connection is achieved by attaching a new grounding ring to the old high-voltage line in the air, using parallel groove clamps to maintain continuity, with both the old and new cables having exposed metal conductors. Current technology includes live-line installation tools for installing parallel groove clamps. Grounding rings are crucial safety devices used for voltage testing and temporary grounding during power line maintenance. Their main function is to provide a reliable grounding connection point for overhead insulated conductors, thereby ensuring the safety of workers. When installing grounding rings, it is absolutely forbidden to touch the high-voltage lines for the following reasons: 1. Residual charge risk: High voltage may remain on the line after a power outage, and contact can still cause electric shock; 2. Step voltage danger: There is a potential difference around the grounding point, and getting close may create a circuit through the human body; 3. Arc discharge: If the high-voltage line is not completely discharged, the air may be broken down, causing arc burns.

[0003] Existing technologies, such as CN202211373510.4 Insulating rod method for installing parallel trench clamps for live-line work in distribution networks and CN202210034583.4 Parallel trench clamp live-line connection device, mostly achieve the installation of parallel trench clamps remotely without interrupting power.

[0004] However, the following technical problems still exist: Currently, most parallel groove clamps are installed horizontally. Since the upper and lower clamps are constrained by bolts, it is difficult to ensure that they can be directly inserted into the grounding ring and busbar. To put it more bluntly, the opening spacing of the parallel groove clamp is equal to or even insufficient with the metal part and core diameter of the high-voltage wire of the grounding ring, making it difficult to insert. Operators need to remove the equipment for adjustment. Therefore, on de-energized wires, you can see installers directly adjusting the angle of the upper and lower clamps to quickly insert the grounding ring or high-voltage wire. Summary of the Invention

[0005] Through practice and summarization, the inventors have derived the technical solution of this invention, proposing a grounding ring replacement device and working method to solve the technical problem that the angle between the upper clamping plate and the lower clamping plate cannot be manually adjusted while energized, thereby facilitating the insertion of the grounding ring and the high-voltage line.

[0016] In a further technical solution, an optical axis guide rail is installed inside the main base.

A movable bracket is installed on the top of the optical axis spring, and the bottom of the optical axis spring is fixedly connected to the main base.

[0017] A drive motor is installed at the bottom of the movable support. The output end of the drive motor passes through the movable support and a drive gear is installed at the top. The drive gear meshes with a transmission gear, which is installed at the bottom of the grooved sleeve.

[0018] A method for operating a grounding ring repair device includes the following steps:

[0019] S1. At a low position, install a parallel groove clamp, connect the upper clamp plate and the lower clamp plate with a parallel groove bolt, and loosen the lock nut on the parallel groove bolt beforehand.

[0020] S2. Pull out the tie rod and adjust the distance between the moving plate and the fixed plate; insert the lock nut into the grooved sleeve, the top of which is a hexagonal sleeve that fits the lock nut; insert the fixing blocks on both sides of the upper clamping plate into the guide seat;

[0021] S3. The vertical spacing between the upper clamp and the lower clamp relative to the installation positions of the grounding ring and the high-voltage line is a and b, respectively. Initially, a and b are of equal size.

[0022] S4. Rotate the push-pull rod. The bottom of the push-pull rod drives the guide seat to slide along the arc-shaped guide groove, first making a larger and b smaller, so that the grounding hanging ring can be inserted.

[0023] S5. Install the grounding ring, placing the exposed metal part of the grounding ring between the upper and lower clamps, with the diameter of the metal part being smaller than the spacing a; insert the sheath of the grounding ring into the elastic clamp tube.

[0024] S6. By manually rotating the push-pull lever in the opposite direction, a becomes smaller and b becomes larger; first restore the equal values, then make b > a;

[0025] S7. At a low position, the external controller drives the electric cylinder to rotate, and the electric cylinder drives the plug plate to move. The top rack of the plug plate meshes with the auxiliary gear, and the plug plate stops moving to prevent the push-pull rod from rotating.

[0026] S8. Install the insulating rod, connect the flange to the insulating rod with a thread, and install anti-loosening bolts on the top;

[0027] S9. Lift the insulating rod to the working area of ​​the high-voltage line, and guide the exposed core of the high-voltage line into the space between the upper and lower clamping plates; the electric cylinder outputs a secondary output, which drives the plug plate forward, causing the rack to mesh with the auxiliary gear to rotate. The rotation of the auxiliary shaft drives the push-pull rod to rotate, making a larger and b smaller, so that the upper and lower clamping plates clamp the high-voltage line; the guide seat is located in the lower part of the upper cavity;

[0028] S10. The drive motor runs, and the optical shaft spring returns to its original deformation upwards; through the drive gear meshing with the transmission gear, it drives the grooved sleeve to rotate, and drives the locking nut to rotate upwards along the grooved bolt; thus completing the clamping of the high-voltage line by the upper and lower clamping plates.

[0029] S11. Pull the insulating rod downwards to detach the fixing block from the top of the guide seat and detach it from the moving plate through the upper cavity; the main base drives the elastic clamp tube to detach from the grounding ring, the hexagonal sleeve to detach from the adjusting nut, and the entire re-installation device to detach from the work area.

[0030] Beneficial effects:

[0031] 1) This invention uses a pre-clamping assembly to constrain and clamp the upper and lower clamping plates, maintaining their distance to facilitate the insertion of the grounding ring. Movable and fixed plates on both sides of the upper clamping plate are connected to fixed blocks on both sides of the upper clamping plate. A pushing mechanism allows the upper clamping plate to slide along an arc-shaped guide groove, enabling angle adjustment between the upper and lower clamping plates and thus changing the distance between them, facilitating the installation of the grounding ring and the high-voltage line.

[0032] 2) The present invention sets the rod body of the push-pull rod to rotate within the upper cavity, and the bottom through the telescopic part structure to realize the constraint guide seat to rotate with the push-pull rod and slide along the limiting groove; because of the arc-shaped guide groove constraint, the sliding is arc-shaped, and it rotates synchronously with the upper clamping plate on the groove bolt, thereby realizing the rotation of the upper clamping plate relative to the lower clamping plate and realizing the adjustment of the distance between the upper and lower clamping plates.

[0033] 3) This invention uses an electric cylinder to drive the forward movement, causing the rack and auxiliary gear one to mesh, thereby rotating the auxiliary shaft. The auxiliary gear two on the auxiliary shaft meshes with the synchronous gear, driving the rotation of the push rod. Using an electric cylinder drive eliminates the need for manual adjustment of the push rod, avoiding the problem of difficulty in manually accessing the push rod when using an insulated rod to hang high-voltage lines at heights.

[0071] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. The application principles of this invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0072] Example 1

[0073] like Figures 1 to 18The image shows one embodiment of the present invention. Specifically, it is a grounding ring repair device, including a grounding ring 100 and a high-voltage line 200. The high-voltage line has a sheath and a core. The grounding ring consists of a sheath and a metal component, typically with a circular connection point, analogous to the core structure. The core is usually aluminum wire. The parallel groove clamp primarily serves to clamp the grounding ring and the high-voltage line together and conduct electricity, extending the high-voltage line. The grounding ring is connected to the ground via a conductor. The parallel groove clamp repair device works by clamping one end of the clamp to the exposed core of the grounding ring, and the other end is attached to the exposed portion of the high-voltage line in the air. The repair device locks the parallel groove clamp and connects the grounding ring and the high-voltage line. After installing the parallel groove clamp, the repair device is detached from the high-voltage line by traction or pulling, leaving only the high-voltage line, busbar, and parallel groove clamp in the air. Currently, manual connection is used for grounding rings and busbars that are de-energized. For energized high-voltage lines, an insulating rod is needed to support the repair device and guide its connection to the high-voltage line. Operators can climb or sit on engineering vehicles to connect high-voltage lines by supporting the insulating poles with their hands.

[0074] like Figure 1 , 4 -6 shows a parallel groove clamp 1, which includes an upper clamp plate 11 and a lower clamp plate 12. The upper clamp plate 11 is provided with an installation arc groove 13 and a parallel groove bolt 14 is installed between it and the lower clamp plate 12. A locking nut 15 is installed on the parallel groove bolt 14 at the bottom of the lower clamp plate 12. Fixing blocks 16 are installed on both sides of the upper clamp plate 11.

[0075] in, Figure 6 The image shows the installation of the arc groove 13, and the remaining space for the insertion of the arc groove and groove bolts is the rotation angle range of the upper clamping plate.

[0076] like Figure 1-3 As shown, a main base 2 is installed inside the main base 2, and a grooved sleeve 21 is installed on the main base 2. The driving structure is used to drive the grooved sleeve 21 to rotate. The top of the grooved sleeve 21 is adapted to the locking nut 15. The grooved sleeve drives the locking nut to rotate along the bolt thread of the grooved bolt. The top diameter of the grooved sleeve is larger than the diameter of the grooved bolt and adapts to the outer wall of the locking nut. Therefore, the top of the grooved sleeve is set to be hexagonal to adapt to the hexagonal outer wall of the locking nut. The insulating rod 3 is detachably connected to the main base 2 at its top. The pre-clamping assembly 4 includes a moving plate 41, a fixed plate 42, and a clamping member. The clamping member drives the moving plate 41 to move toward or away from the fixed plate 42. Both the moving plate 41 and the fixed plate 42 are provided with arc-shaped guide grooves 43, and the two sides of the upper clamping plate 11 are located in the arc-shaped guide grooves 43. The pre-clamping assembly 4 includes a pushing mechanism, which drives the upper clamping plate 11 to slide along the arc-shaped guide grooves 43, so that the upper clamping plate 11 rotates relative to the lower clamping plate 12.

[0077] The top of the upper clamping plate 11 is arc-shaped, and the center of the arc-shaped guide groove 43 is parallel to the axis of the guide rod 45 between the center of the upper clamping plate 11 and the center of the guide groove 43. The parallel groove clamp 1 also includes a parallel groove clamping plate 17, and a parallel groove bolt 14 passes through the parallel groove clamping plate 17, the upper clamping plate 11 and the lower clamping plate 12. The end of the parallel groove bolt 14 is located on the parallel groove clamping plate 17.

[0078] This invention uses a pre-clamping assembly to constrain and clamp the upper and lower clamping plates, maintaining their distance to facilitate the insertion of the grounding ring. Movable and fixed plates on both sides of the upper clamping plate connect to fixed blocks on both sides. A pushing mechanism allows the upper clamping plate to slide along an arc-shaped guide groove, enabling angle adjustment between the upper and lower clamping plates and thus changing the distance between them. This facilitates the installation of the grounding ring and the high-voltage line. It solves the technical problem of inefficient insertion of high-voltage lines when installed in the air via an insulating rod.

[0079] like Figure 7 As shown, the movable plate 41 and the fixed plate 42 are located on both sides of the parallel groove clamp 1; the clamping member includes a support plate 44, which is fixedly connected to the main base 2. A guide rod 45 is installed between the support plate 44 and the movable plate 41. The end of the guide rod 45 away from the movable plate 41 has a stop part 46 installed outside the support plate 44. The stop part is as follows: Figure 8 As shown, the diameter of the stop is larger than the diameter of the hole passing through the support plate; the moving plate is as follows: Figure 10 and 11 As shown, the fixed plate structure is not drawn, and... Figure 11 Similarly, the guide short shaft shown can be removed. The arc-shaped guide grooves of the fixed plate and the moving plate are adapted to the fixed blocks on both sides of the upper clamping plate. In this application, only one set of moving plates is provided to abut against the upper and lower clamping plates. In actual use, the moving plates of the upper clamping plate and the lower frame plate can be separated into two parts and limited by separate guide rods and guide springs. This invention is not limited to protecting only one set of moving plates and one set of fixed plates correspondingly connected to the upper or lower clamping plate.

[0080] A guide spring 47 is sleeved on the guide rod 45; the two ends of the guide spring 47 are fixedly connected to the moving plate 41 and the support plate 44 respectively; a tie rod 48 is installed on the support plate 44, one end of the tie rod 48 is provided with an end head 481, and the other end passes through the support plate 44 and is fixedly connected to the moving plate 41.

[0081] like Figure 10As shown, a guide seat 49 is slidably mounted on the arc-shaped guide groove 43, and the guide seat 49 is provided with a non-closed slot; the fixing block 16 is adapted to the slot; the top is not closed, so that when the fixing block is inserted, it can be used to pull the insulating rod down to install the device without creating a constraint on detachment from the upper clamping plate. In other practical solutions, it is also possible to consider setting a structure such as a movable plate that can be rotated open on the top of the guide seat. For example, a one-way hinged plate that can be opened upwards.

[0082] The movable plate 41 is located between the grounding ring 100 and the high-voltage line 200, and its width is less than the length of the upper clamping plate 11 between the grounding ring 100 and the high-voltage line 200; a pushing mechanism is installed on the back of the guide seat 49, which drives the guide seat 49 to slide along the arc-shaped guide groove 43, so that the upper clamping plate 11 rotates relative to the lower clamping plate 12.

[0083] A limiting groove 410 is provided under the arc-shaped guide groove 43, and a constraint plate 411 is installed on the limiting groove 410; a limiting block 491 is installed at the bottom of the guide seat 49, and the limiting block 491 is adapted to the limiting groove 410 and slides within the limiting groove 410.

[0084] like Figure 12 As shown, the guide seat 49 includes a base plate 492, side plates 493, and a back plate 494. Two sets of side plates 493 are located on either side of the base plate 492. The back plate 494 is fixedly connected to the two sets of side plates 493 and the base plate 492. The base plate 492 is fixedly connected to the limiting block 491. The two sets of side plates 493 are located at both ends of the base plate 492 facing the arc-shaped guide groove 43, and their spacing is adapted to fit the fixing block 16. The bottom limiting block of the guide seat is as follows... Figure 13 As shown, the bending point on the limiting block is constrained by the installation of the constraint plate, thereby achieving the effect of constraining the guide seat, wherein the bottom of the limiting block is in contact with the bottom of the limiting groove.

[0085] refer to Figure 10 An upper cavity 412 is provided on the movable plate 41. The pushing mechanism includes a push-pull rod 413, the rod of which rotates within the upper cavity 412. The upper cavity 412 is connected to the arc-shaped guide groove 43. The depth of the upper cavity 412 is greater than the length of the guide seat 49 along the axis of the grounding ring 100. Figure 14 A telescopic part 414 is provided at the bottom of the push-pull rod 413, and the bottom of the telescopic part 414 is hinged to the side of the back plate 494 opposite to the side plate 493; for example Figure 15 and 16As shown, the telescopic part 414 includes a connecting post 4141 and a connecting cylinder 4142. Its upper end is fixedly connected to the push-pull rod 413, and its lower end is inserted into the connecting cylinder 4142. A connecting spring 4143 is installed inside the connecting cylinder 4142. One end of the connecting spring 4143 is fixedly connected to the connecting post 4141, and the other end is fixedly connected to the inner wall of the connecting cylinder 4142. A hinge interface is provided at the bottom of the connecting cylinder 4142. Figure 13 As shown, the hinge interface is sleeved on a set of rotating shafts. One end of the rotating shaft is connected to the back plate through a bearing, so that the push-pull rod can rotate relative to the back plate without disengaging, and the push-pull rod can push the guide seat along the limiting groove.

[0086] like Figure 17 and 18 As shown, a guide short shaft 415 is installed at the rotation position of the push-pull rod 413 inside the movable plate 41. One end of the guide short shaft 415 is located inside the movable plate 41 and is equipped with a connecting bearing 416. Figure 18 As shown, the other end is fixed to the push-pull rod 413; the connection can be made using one of the following methods: slot plate, key, or screw fastening.

[0087] This invention features a push-pull rod whose body rotates within the upper cavity, while the bottom, through a telescopic structure, allows the guide seat to rotate as the push-pull rod is pushed, sliding along the limiting groove. Due to the constraint of the arc-shaped guide groove, the sliding is arc-shaped and rotates synchronously with the upper clamping plate on the grooved bolt, thereby achieving the rotation of the upper clamping plate relative to the lower clamping plate and adjusting the distance between the upper and lower clamping plates.

[0088] Example 2

[0089] like Figure 19-25 As shown, this is another embodiment of the present invention, based on embodiment 1, as follows: Figure 19 As shown, an electric cylinder 5 is also installed on the main base 2. A connector plate 51 is installed at the end of the electric cylinder 5 facing the moving plate 41. The connector plate 51 is C-shaped, as shown... Figure 21 As shown, it includes an upper plate portion 511 and a lower plate portion 512, wherein the length of the upper plate portion 511 is greater than the length of the lower plate portion 512; as Figure 24 As shown, a synchronous gear 419 is mounted on the guide short shaft 415, and the synchronous gear 419 is located in the upper cavity 412; the insertion direction of the plug plate is perpendicular to the axis of the high voltage line and the grounding ring.

[0090] like Figure 25As shown, an auxiliary shaft 417 is inserted into the movable plate 41, and the auxiliary shaft 417 is parallel to the guide short shaft 415. An auxiliary gear 1 418 and an auxiliary gear 2 420 are installed at the end of the auxiliary shaft 417. The auxiliary gear 1 418 is located between the movable plate 41 and the support plate 44, and the auxiliary gear 2 420 meshes with the synchronous gear 419. A rack 513 is provided on the inner wall of the upper plate 511. The rack 513 meshes with the auxiliary gear 1 418. The height of the upper plate 511 and the lower plate 512 is greater than the diameter of the grounding ring 100. The meshing of the rack and auxiliary gear 1 drives the synchronous gear to rotate, which needs to be compatible with the rotation angle of the push-pull rod. The rotation of the push-pull rod in the upper cavity is limited by the side wall of the upper cavity.

[0091] like Figure 22 and 23 As shown, it includes an auxiliary gear and a synchronizing gear, which mesh with each other, and their spatial positions are as follows. Figure 22 As shown, it does not interfere with the rotation of the push-pull rod and the upward movement of the fixing block on the guide seat. The top of the main base 2 is provided with a position plate 22 and an opening, through which the grooved sleeve 21 passes; position plates 22 are provided on both sides of the opening; an electric cylinder 5 is mounted on one set of position plates 22, and a fixing block 16 and an elastic clamping tube 23 are mounted on the other set of position plates 22, as shown. Figure 19 As shown, the elastic clamp tube 23 is used to clamp the sheath of the grounding ring 100; a flange 24 is installed on the outer wall of the main base 2, the flange 24 has an internal thread and is threaded to the insulating rod 3, and an anti-loosening bolt 25 is installed in the flange 24, such as Figure 20 As shown, this prevents the insulating rod from rotating and falling off.

[0092] This invention uses an electric cylinder to drive the forward movement, causing the rack and auxiliary gear to mesh, thus rotating the auxiliary shaft. The auxiliary gear on the auxiliary shaft then meshes with a synchronous gear, driving the rotation of the push rod. By using an electric cylinder drive, the push rod can be adjusted without manual rotation, avoiding the problem of difficulty in manually accessing the push rod when using an insulated rod to hang high-voltage lines at heights.

The optical axis spring continuously pushes the movable bracket upwards, allowing the grooved sleeve on the movable bracket to move upwards along the axis of the grooved bolt when the locking nut is rotated. This pushes the lower clamping plate to move upwards, thus achieving the effect of constraining the grounding ring and high-voltage line by the upper and lower clamping plates when the locking nut is rotated. Figure 28 The diagram shows a cross-section of the grounding ring marked 100.

[0095] like Figure 29 As shown, the movable bracket 6 has a connecting hole, and a guide sleeve 61 is installed at the connecting hole.

In this embodiment, an optical axis spring is provided to support the movable bracket upward on the optical axis guide rail, keeping the grooved sleeve fitted with a locking nut on the grooved bolt, and allowing it to continuously move upward during rotation. A drive motor is provided to drive the grooved sleeve to rotate via a drive gear and a transmission gear.
