[0002] During the maintenance process of power workers, the grounding wire can prevent the workers from getting close to the live body and generating electrostatic induction. It can also ensure the safety of the workers when the switch is closed by mistake. It is difficult to temporarily install the grounding wire, so installing a reliable insulating grounding wire clamp is the key to ensuring the personal safety of power workers. The structure of the existing insulating grounding wire clamp is as described in the patent number "CN217485735U", including a disk body as the main body of the insulating grounding wire clamp, a detachable gland on the disk body, an insulating cover hinged with the disk body, and a grounding ring connected to the disk body. During installation, the cable is first fixed between the gland and the disk body, and the gland moves toward the disk body by screwing the wire clamp bolt to clamp the cable. After clamping, the insulating cover is closed to complete the installation process.

[0003] When working on live distribution networks, installing grounding wire clamps generally requires power workers to climb to the top or use an insulated boom truck to reach the working height, and manually tighten the clamp bolts with a wrench to complete the installation of the grounding wire clamp. Manual live working at height is time-consuming and labor-intensive, and there are safety risks. At the same time, due to its own structural reasons, the grounding wire is not firmly connected when it is hung on a suspended vertical conductor or in strong winds, which can easily cause the conductor to slip off the clamp, increasing the operating risk of maintenance personnel and therefore needs to be urgently resolved.

[0011] As a further solution of the present invention: the sliding groove is a two-stage sliding groove. Along the direction away from the wire clamp bolt, the sliding groove includes a straight section and a downward inclined climbing section. The sliding frame is provided with a guide rack arranged in parallel with the straight section of the sliding groove.

The fixed end and the telescopic end of the electric push rod are respectively hingedly cooperated with the first connecting rod and the fastening baffle. When the electric push rod is in a telescopic state, it drives the fastening baffle to flip around the hinge point between the fastening baffle and the first connecting rod.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. After the mounting seat is sent to the working height, the striking seat first moves along the sliding groove to apply a locking action to the wire clamp bolt. After locking, the striking seat retreats and then flips the insulating cover to make the lock buckle on the insulating cover abut against the lock tongue. The striking seat then moves along the sliding groove, and during the movement, the first connecting rod drives the fastening baffle to abut against the lock buckle. When the electric push rod is started, the lock buckle can be flipped to complete the locking of the lock tongue, thereby realizing the automatic installation of the grounding wire clamp with low operation risk.

[0016] 2. The sliding groove of the present invention is set as a two-stage sliding groove. In the initial state, when the gear shaft is located at the junction of the climbing section and the straight section of the sliding groove, there is a V-shaped opening between the striking seat and the pressure cover, which makes room for the rotating cover of the insulating cover. When the support frame drives the striking seat to slide along the sliding groove, the gear shaft first slides along the straight section of the sliding groove. At this time, the guide rod slides along the climbing section of the sliding groove. During this process, the striking seat makes a pitching motion and is in an inclined state. Continue to slide until the guide rod enters the straight section of the sliding groove. At this time, the striking seat is converted from an inclined state to a straight state, and moves in the direction of the wire clamp bolt until the wire clamp bolt enters the plum blossom sleeve. After the tightening of the wire clamp bolt is completed, the motor gear drives the gear shaft to reverse, and the support frame drives the striking seat to retreat to the initial state; the entire working process fully utilizes the narrow installation space in the horizontal direction, and the two-stage stroke of the striking seat makes room for the rotation of the insulating cover, thereby improving the space utilization in the horizontal direction.

[0017] 3. When the support frame of the present invention moves along the sliding groove, it drives the first connecting rod and the second connecting rod to produce a V-shaped opening and closing operation. When the support frame is away from the mounting seat, the opening and closing angle between the first connecting rod and the second connecting rod reaches the maximum. At this time, the first connecting rod moves downward to avoid the flipping trajectory of the insulating cover. When the support frame is adjacent to the mounting seat, the opening and closing angle between the first connecting rod and the second connecting rod is the smallest. At this time, the fastening baffle installed on the first connecting rod abuts against the lock on the grounding wire clamp; through the extension and retraction of the electric push rod, the fastening baffle can be driven to flip around the hinge point between the fastening baffle and the first connecting rod, and the lock is pushed to flip synchronously during flipping, thereby completing the locking of the lock and the lock tongue, and the fastening baffle is driven to move by the support frame to make room for the rotation of the insulating cover.

[0018] 4. When the wire claw push rod of the present invention is extended and retracted, it forms a V-shaped two-link structure with the shaft connecting rod. When extended and retracted, it drives the shaft to rotate. After the shaft drives the wire pressing claw to rotate, the wire pressing claw can press the cable to the bottom of the guide channel from top to bottom to avoid the shaking of the cable in the working state; when the wire claw push rod is retracted to the limit state, it is arranged in a straight line with the shaft connecting rod. At this time, the wire claw push rod is arranged in parallel with the gland push rod to maximize the space utilization. The gland push claw rotates coaxially with the gland gear, and produces a pressing action on the insulation cover when rotating. The insulation cover is pressed by the 180-degree rotation of the gland push claw. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] See also Figures 1 to 8 In an embodiment of the present invention, a live installation method for an insulated grounding clamp of a power distribution line is provided. The steps include: S1. Insert the grounding wire clamp 1 into the mounting seat 2 of the grounding wire clamp mounting device, and use an insulating rod to hold the grounding wire clamp mounting device or remotely control the grounding wire clamp mounting device to reach a set installation height; S2, clamp the ground wire into the clamping groove of the ground wire clamp 1, hit the clamp bolt 13 of the ground wire clamp 1, and press the ground wire into the clamping groove through the gland 12; S3, turning over the insulating cover 11, and covering the insulating cover 11 on the outside of the gland 12; S4, flip the lock buckle 16 on the insulating cover 11, so that the grounding wire clamp 1 is inserted into the lock hole of the lock buckle 16; S5. Remove the grounding clamp installation device to separate it from the grounding clamp 1 to complete the installation. After the installation is completed, use a ground resistance tester to test the grounding system to ensure that the grounding resistance meets the requirements. If the test result does not meet the requirements, remove the grounding clamp and readjust the installation position, and repeat steps S1 to S5.

[0030] During the installation process, mark the grounding clamp 1 and cable A to facilitate subsequent inspection and maintenance. At the same time, record relevant information such as the installation date and ground resistance test results for future reference.

[0031] Before installation, you need to strip a certain length of the insulation layer of cable A to expose the bare copper wire. At the same time, remove debris, dust and moisture from the installation area to ensure that the wire clamp can closely contact the installation surface.

[0032] The following is a detailed introduction to the grounding clamp installation device: The grounding wire clamp installation device comprises a detachable grounding wire clamp 1, a mounting seat 2 for positioning the grounding wire clamp 1, a locking mechanism 3 and a buckling mechanism 4.

[0033] Grounding clamp 1: The grounding clamp 1 comprises a base body and a grounding ring 14 arranged below the base body. Preferably, a groove is provided below the base body, and the grounding ring 14 is positioned by clamping.

[0034] The base of the grounding clamp 1 is provided with a wire clamping groove for the cable A to be clamped in. A gland 12 is installed on the base, and the gland 12 is fixed to the base by a wire clamp bolt 13. A wire clamping groove of a corresponding shape is provided at one end of the gland 12 adjacent to the wire clamping groove. When the wire clamp bolt 13 is screwed to move the gland 12 toward the wire clamping groove, the wire clamping groove of the gland 12 is closed with the wire clamping groove to enclose a wire channel, thereby clamping and fixing the cable A.

[0035] The insulating cover 11 is hinged to the base of the grounding clamp 1, so that the gland 12 can be placed inside the cover of the insulating cover 11 after being turned over from top to bottom. A grounding ring groove is provided on the cover of the insulating cover 11. When the insulating cover 11 is closed, the grounding ring 14 is just located in the grounding ring groove of the insulating cover 11. The grounding ring 14 is positioned by the restrictions of the insulating cover 11 and the base. The hinge axis of each structure in the present application is parallel to the turning axis of the insulating cover 11.

[0036] A locking tongue 15 is protruding from the bottom of the grounding clamp 1, and a locking buckle 16 is provided on the insulating cover 11. When the insulating cover 11 is covered, the locking buckle 16 corresponds to the position of the locking tongue 15. The locking buckle 16 is preferably made of a flexible rubber material that can be bent. By applying an external force to the locking buckle 16, it can be turned ninety degrees from the root. A locking hole is provided on the surface of the locking buckle 16, and the locking hole corresponds to the shape of the locking tongue 15 or is slightly smaller than the locking tongue 15. When the locking buckle 16 is turned over by an external force, the locking tongue 15 passes through the locking hole of the locking buckle 16, thereby completing the locking of the insulating cover 11 and the seat body, and preventing the insulating cover 11 from opening.

[0037] Mount 2: The shape is not limited, and is preferably a vertical plate-like structure. The snap-fit ​​mechanism 4 is fixed on the back of the mounting seat 2, and the locking mechanism 3 is fixed on the front of the mounting seat 2, so that the mounting positions avoid each other.

[0038] A slot is provided on the mounting seat 2 in the vertical direction, and the grounding ring 14 of the grounding clamp 1 can be snapped into the slot of the mounting seat 2 from top to bottom, thereby forming a detachable fit with the grounding clamp 1. In the process of lifting the mounting seat 2 to the working height by the insulating rod, the mounting seat 2 can exert a lifting action on the grounding clamp 1. After the grounding clamp 1 is installed and connected to the cable A, the mounting seat 2 is moved vertically downward, so that the grounding clamp 1 and the mounting seat 2 can be disengaged by sliding, and the disassembly work is completed.

[0039] In order to improve stability, a manual or automatic locking device may be installed to improve the connection strength between the grounding clamp 1 and the mounting base 2 so that the grounding clamp 1 and the mounting base 2 are detachably fixed.

[0040] Locking mechanism 3: It comprises two sets of parallel and symmetrically arranged sliding frames 33 , the sliding frames 33 are arranged perpendicularly to the base of the grounding clamp 1 , and the distance between the two sliding frames 33 is greater than the width of the insulating cover 11 , so as to be staggered with the flipping track of the insulating cover 11 .

[0041] The device further comprises two sets of support frames 31 arranged in parallel, and the two support frames 31 can be connected and fixed by a connecting rod 314. The two support frames 31 are used to fix the striking seat 32 for screwing the wire clamp bolt 13.

[0042] The striking seat 32 includes a front mounting seat and a rear mounting seat, which are fixedly connected by multiple aluminum columns. Two groups of impact blocks rotate between the front mounting seat and the rear mounting seat. The brushless motor is arranged on the rear mounting seat. The brushless motor and the impact block are driven by gears. The gear mounting seat and the front mounting seat are fixedly connected. The tightening gear and the tightening drive gear rotate therebetween. The tightening gear is connected to the plum blossom sleeve 321 through a rotating shaft. The brushless motor rotates at high speed to drive the two groups of impact blocks to rotate, and drives the two groups of plum blossom sleeves 321 to rotate by gear transmission. After the plum blossom sleeve 321 is aligned with the wire clamp bolt 13, it applies a screwing force to the wire clamp bolt 13 while rotating. A group of clamping springs 322 are arranged on the sides of the two groups of plum blossom sleeves 321. When the plum blossom sleeve 321 is aligned with the wire clamp bolt 13, the two groups of clamping springs 322 apply a pressing force to the pressure cover 12 to ensure the stability of the striking process.

[0043] The sliding frame 33 is provided with a sliding groove 331, which is a two-stage sliding groove, one of which is a straight section arranged along the screwing direction of the wire clamp bolt 13, and the other section of the sliding groove is a climbing section arranged downwardly inclined, and the climbing section and the straight section directly and smoothly transition, and the length of the climbing section is less than the length of the straight section. The side of the sliding frame 33 is provided with a guide rack 332 corresponding to the position of the straight section of the sliding groove 331 and arranged parallel to each other. A motor is placed horizontally between the two support frames 31, and the motor shaft drives the motor gear 323 to rotate. A gear shaft 312 is provided between the two support frames 31 to rotate with the support frame 31, and the driving gear 313 on the gear shaft 312 is meshed with the motor gear 323. Guide gears 333 are fixed at both ends of the gear shaft 312. The guide gear 333 and the guide rack 332 form a gear-rack match. The motor gear 323 drives the gear shaft 312 to rotate through the active gear 313. At the same time, through the gear-rack match, the striking seat 32 fixed on the support frame 31 moves along the sliding groove 331.

[0044] A guide rod 311 is also provided between the two support frames 31. The guide rod 311 is arranged in the sliding groove 331. The support frame 31 slides with the sliding groove 331 through the guide rod 311. When the support frame 31 is farthest from the gland 12, the end of the guide rod 311 abuts against the bottom end of the climbing section of the sliding groove 331, and the gear shaft 312 is located at the junction of the climbing section and the straight section of the sliding groove 331. The spacing between the gear shaft 312 and the guide rod 311 is preferably equal to the length of the climbing section of the sliding groove 331.

[0045] In the initial state, when the gear shaft 312 is located at the junction of the climbing section and the straight section of the sliding groove 331, there is a V-shaped opening between the striking seat 32 and the pressure cover 12, which makes room for the rotating cover of the insulating cover 11. When the support frame 31 drives the striking seat 32 to slide along the sliding groove 331, the gear shaft 312 first slides along the straight section of the sliding groove 331, and the guide rod 311 slides along the climbing section of the sliding groove 331. During this process, the striking seat 32 performs a pitching motion and is in an inclined state. Continue to slide until the guide rod 311 enters the straight section of the sliding groove 331, and the striking seat 32 is converted from an inclined state to a straight state. And move in the direction of the wire clamp bolt 13 until the wire clamp bolt 13 enters the plum blossom sleeve 321. After completing the screwing of the wire clamp bolt 13, the motor gear 323 drives the gear shaft 312 to reverse, and the support frame 31 drives the striking seat 32 to retreat to the initial state.

[0046] The support frame 31 is also equipped with a clamping assembly 34 for applying a clamping and flipping action to the lock buckle 16. The clamping assembly 34 includes a first connecting rod 341. The shape of the first connecting rod 341 is not limited, and it is preferably in a three-stage step shape, and the three stages are parallel to each other. The lower stage of the first connecting rod 341 is hinged with the fixed end of the electric push rod 342, the middle stage of the first connecting rod 341 is hinged with the connecting rod 314, and the first connecting rod 341 is arranged in the middle of the connecting rod 314. The upper stage of the first connecting rod 341 is hinged with the second connecting rod 343, and the other end of the second connecting rod 343 is hinged with the mounting seat 2. When the support frame 31 moves along the sliding groove 331, it drives the first connecting rod 341 and the second connecting rod 343 to produce a V-shaped opening and closing operation. When the support frame 31 is away from the mounting seat 2, the opening and closing angle between the first connecting rod 341 and the second connecting rod 343 reaches the maximum. At this time, the first connecting rod 341 moves downward to avoid the flipping trajectory position of the insulating cover 11. When the support frame 31 is adjacent to the mounting seat 2 , the opening and closing angle between the first connecting rod 341 and the second connecting rod 343 is the smallest. At this time, the fastening baffle 344 installed on the first connecting rod 341 abuts against the lock buckle 16 on the grounding clamp 1 .

[0047] One end of the fastening baffle 344 is hinged to the upper stage of the first connecting rod 341, and the distance between the hinge point and the lock buckle 16 is smaller than the distance between the hinge point of the second connecting rod 343 and the lock buckle 16. The other end of the fastening baffle 344 is hinged to the electric push rod 342, and the fastening baffle 344, the electric push rod 342 and the first connecting rod 341 form a closed three-link hinged in sequence. Through the extension and retraction of the electric push rod 342, the fastening baffle 344 can be driven to flip around the hinge point of the fastening baffle 344 and the first connecting rod 341, and the lock buckle 16 is pushed to flip synchronously during the flipping, thereby completing the locking of the lock buckle 16 and the lock tongue 15.

[0048] During the installation process, the striking seat 32 first moves along the sliding groove 331 to apply a locking action to the wire clamp bolt 13, and then the striking seat 32 retreats after locking. Then the insulating cover 11 is turned over to make the lock buckle on the insulating cover 11 abut against the lock tongue 15, and the striking seat 32 moves along the sliding groove 331 again. When moving, the first connecting rod 341 drives the fastening baffle 344 to abut against the lock buckle 16, and the electric push rod 342 is started to turn the lock buckle 16 to complete the locking of the lock tongue.

[0049] Fastening mechanism 4: It includes a front guide fork 41 and a rear guide fork 42 fixed on the mounting base 2. The front guide fork 41 and the rear guide fork 42 enclose a guide channel 43 with a V-shaped opening. The opening of the guide channel 43 is upward, and the bottom end of the guide channel 43 is coaxially arranged with the wire clamping groove of the grounding wire clamp 1.

[0050] The rear guide fork 42 is located between the front guide fork 41 and the locking mechanism 3 , and the bottom end of the guide channel 43 is curved to position cables A of different diameters. The front guide fork 41 and the rear guide fork 42 are preferably provided in two groups, and the mounting seat 2 is provided between the two front guide forks 41 and the two rear guide forks 42 .

[0051] A limiting rod 411 is disposed at the top end between the two front guide forks 41 . The limiting rod 411 is located on the flipping track of the lock buckle 16 . The lock buckle 16 can go over the limiting rod 411 after being bent.

[0052] A rotating shaft 413 is provided at the bottom end between the two front guide forks 41 , and wire pressing claws 412 are provided at both ends of the rotating shaft 413 . The pressing surface of the wire pressing claws 412 is in an arc shape and is used to fit the cable A.

[0053] After the rotating shaft 413 drives the wire pressing claw 412 to rotate, the wire pressing claw 412 can press the cable A against the bottom of the guide channel 43 from top to bottom to prevent the cable A from shaking.

[0054] A wire claw push rod 44 is provided on the back of the mounting base 2 and is hingedly arranged with the mounting base 2. The driving end of the wire claw push rod 44 is hingedly matched with the rotating shaft connecting rod 414. The end of the rotating shaft connecting rod 414 is fixed on the rotating shaft 413. When the wire claw push rod 44 is extended and retracted, it forms a V-shaped two-link structure with the rotating shaft connecting rod 414, driving the rotating shaft 413 to rotate during extension and retraction.
