Description

Technical Field

[0001] The present invention relates to the technical field of power grid operation, maintenance and repair, and more particularly to a grounding wire hanging and removing device and method. Background Art

[0002] Before carrying out maintenance work on power-off lines or equipment, a grounding wire must be installed. This can prevent injuries from induced voltage on the one hand, and can effectively avoid personal injury to maintenance personnel due to accidental power supply on the other. Traditional grounding wire installation work usually requires workers to carry the grounding wire up the tower, and then carry out the work layer by layer and phase by phase, and then remove it in sequence after the work is completed. The traditional grounding method consumes a lot of physical energy for workers, and there are also risks such as injuries from induced voltage and falls from heights. With the widespread application of drone and robot technology in the maintenance of power transmission lines, combining drones with grounding wire installation technology can effectively improve the efficiency of maintenance operations and ensure operational safety. However, the electronic control method used in existing technologies is limited by the influence of the high-altitude environment, the poor reliability of the mechanical structure, and insufficient clamping force, which leads to the risk of intermittent disconnection of the grounding wire connection.

[0064] Various embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. In each of the accompanying drawings, identical elements are represented by identical or similar reference numerals. For the sake of clarity, the various parts in the accompanying drawings are not drawn to scale.

[0065] The present invention provides a ground wire hanging and detaching device, which includes a conductor end hanging and detaching device and a tower end hanging and detaching device. The conductor end hanging and detaching device includes a conductor clamping mechanism 6 and a first ground wire locking mechanism. The conductor clamping mechanism 6 is used to hang on the conductor and clamp the conductor via a drone. The first ground wire locking mechanism is connected to the lower end of the conductor clamping mechanism 6 and is used to lock and fix the high-voltage end of the ground wire. Figure 1 and Figure 2The pole tower end hanging and disassembly device includes a hook body 1, an adaptive clamping mechanism 2, a top linkage unlocking mechanism 3 and a second ground wire locking mechanism 4; the adaptive clamping structure is arranged on the hook body 1, and is used to clamp the hook body 1 on the angle steel of the pole tower after the hook body 1 is hung on the pole tower; the top linkage unlocking mechanism 3 is arranged at the top of the hook body 1, and is used to be connected to the drone. The top linkage unlocking mechanism 3 is connected to the adaptive clamping mechanism 2 through a steel wire rope 51 to control the adaptive clamping mechanism 2 to unlock; the second ground wire locking mechanism 4 is arranged at the lower end of the hook body 1, and is used to lock and fix the low-voltage end of the grounding wire.

[0066] The conductor end hanging and removing device and the tower end hanging and removing device of the grounding wire hanging and removing device can respectively realize the hanging of the high-voltage end and the low-voltage end of the grounding wire through drones. The operation is simple and convenient, and there is no need to climb high during the operation, which reduces the difficulty of operation and safety risks, and improves the flexibility, reliability and safety of the grounding wire hanging.

[0067] See also Figure 3 In the pole tower end hanging and disassembly device, the hook body 1 includes two hook side plates 11 set at a distance from each other, and a plurality of fixed support blocks 12 fixedly connected between the two hook side plates 11; the hook side plates 11 include a first vertical plate 111 and a second vertical plate 112 set vertically at a distance from each other, and a horizontal plate 113 connected to the top of the first vertical plate 111 and the second vertical plate 112; two clamping support blocks 13 are also provided between the two hook side plates 11, and the two clamping support blocks 13 are respectively located at the upper end of the first vertical plate 111 and the upper end of the second vertical plate 112; the adaptive clamping mechanism 2 is rotatably provided between the two clamping support blocks 13.

[0068] Specifically, the hook side plate 11 is a hook-shaped structure with an opening downward. The length of the first vertical plate 111 of the hook side plate 11 is smaller than the length of the second vertical plate 112. The width of the lower end of the second vertical plate 112 where it connects to the second ground wire locking mechanism 4 is larger to facilitate the arrangement of the second ground wire locking mechanism 4. The hook side plate 11 is cut from a steel plate of a certain thickness. While meeting the strength requirements, the hook side plate 11 is also provided with a number of oblong holes in the shape of weight reduction holes to reduce the overall weight of the device and facilitate the carrying and mounting of drones. The fixed support block 12 and the clamping support block 13 are respectively fixedly connected to the two hook side plates 11 by screws to achieve the connection and fixation between the two hook side plates 11. The hook body 1 serves as the main mounting frame of the pole tower end mounting and dismounting device. The top linkage unlocking mechanism 3, the adaptive clamping mechanism 2 and the second ground wire locking mechanism 4 are all installed on the hook body 1.

[0069] See also Figure 4 and Figure 5The adapter clamping mechanism 2 includes a rotating seat 21, a hook plate 22, a lifting plate 23, a sliding seat 24, a clamping plate 25, an unlocking piece 26 and an unlocking plate 27; wherein, the two ends of the rotating seat 21 in the length direction are rotatably connected to the hook body 1, and a first compression spring 216 is provided on the rotating seat 21 along its length direction; the sliding seat 24 is slidably connected to the rotating seat 21 along the length direction of the rotating seat 21, the clamping plate 25 is connected to the sliding seat 24, and the clamping plate 25 is located below the rotating seat 21; the unlocking piece 26 is rotatably connected to the sliding seat 24, and the unlocking piece 26 includes a blocking end 261 and a pressure end 262, and the blocking end 261 can abut against one end of the first compression spring 216; the first end of the hook plate 22 is rotatably connected to the sliding seat 24, and the second end of the hook plate 22 is provided with a downwardly extending When the cam 22 is in engagement with the latch 241 of the first lever 22, the first end 23 of the first lever 22 is engaged with the first end 23 of the second lever 22, and the second end 23 of the first lever 22 is engaged with the first end 23 of the second lever 22.

[0070] See also Figure 6The rotating seat 21 has a trough-shaped structure and includes a rotating seat base plate and two rotating seat end plates, which are vertically connected at both ends of the rotating seat base plate in the longitudinal direction. A contact copper plate 215 is provided at the bottom of the rotating seat 21. This contact copper plate 215 allows the rotating seat 21 to mate with the angle steel at the end of the tower, increasing the contact surface and reducing grounding resistance. Each of the two rotating seat end plates is provided with a sheave seat 213, on which a sheave 52 is rotatably connected. The sheave 52 is used to guide the wire rope 51. The hook body 1 is also provided with a plurality of sheaves 52. The wire rope 51 guided from the top linkage unlocking mechanism 3 is guided by the sheaves 52 on the hook body 1 and the rotating seat 21 before being connected to the unlocking plate 27. A guide shaft 214 is vertically mounted on the top of each sheave seat 213. A second compression spring 217 is sleeved on the guide shaft 214. The lower end surface of the unlocking plate 27 abuts against the upper end of the second compression spring 217. A top stopper is provided at the top of the guide shaft 214 to prevent the unlocking plate 27 from being dislodged. By arranging the second compression spring 217 on the guide shaft 214, the top linkage unlocking mechanism 3 pulls the wire rope 51, causing the unlocking plate 27 to move downward along the guide shaft 214, pressing the unlocking piece 26 to unlock the vehicle. After this, the unlocking plate 27 automatically returns to its original position under the elastic force of the second compression spring 217.

[0071] Furthermore, two of the first compression spring 216, unlocking piece 26, clamping plate 25, and lifting plate 23 are symmetrically arranged about the center in the width direction of the rotating base 21. Two pins 221 are provided on the hook plate 22, and the two lifting plates 23 are connected to the ends of the two pins 221, respectively. The two lifting plates 23 are respectively located on the outer sides of the rotating base 21 in the width direction.

[0072] Furthermore, a central axis 211 is provided through the center of the rotating seat 21 in the width direction, and the rotating seat 21 is rotatably connected to the hook body 1 via the central axis 211. Two sliding rods 212 are symmetrically provided on either side of the central axis 211. The sliding seat 24 is slidably connected to the central axis 211 and the two inner sliding rods 212. The two first compression springs 216 are respectively mounted on the two outer sliding rods 212. The blocking end 261 of the unlocking piece 26 is provided with a slot 2611 for hooking onto the outer sliding rods 212. By providing the central axis 211 on the rotating seat 21, the rotating seat 21 can be rotatably connected to the hook body 1. The rotating seat can rotate axially in a direction perpendicular to the first and second vertical plates, allowing the adaptive clamping mechanism 2 to adapt to the tilted angle steel at the tower end. The outermost slide bar 212 on the rotating seat 21 can allow the first compression spring 216 to be mounted thereon, and the slot 2611 on the blocking end 261 of the unlocking piece 26 can be mounted on the outermost slide bar 212 to abut against the first compression spring 216 .

[0073] Figure 8 This is a structural diagram of the unlocking piece. As can be seen from the figure, the blocking end 261 and the pressure end 262 of the unlocking piece 26 are connected as a whole at a certain angle. A through hole is provided in the middle of the unlocking piece 26, and the unlocking piece 26 is rotatably connected to the sliding seat 24 by an unlocking pin shaft passing through the through hole.

[0074] See also Figure 7 The sliding seat 24 has an I-shaped structure, including a first end plate and a second end plate arranged in parallel. The first end plate and the second end plate are connected by a connecting plate. The snap-in hole 241 is set on the second end plate. The two unlocking pieces 26 are rotatably connected to both sides of the second end plate in the width direction through the unlocking pin shaft, and the two unlocking pieces 26 are symmetrically arranged. That is, the blocking ends 261 of the two unlocking pieces 26 can be clamped on the outer sliding rod 212 of the rotating seat 21 through the clamping groove 2611, and abut against the first compression spring 216. The compressed ends 262 of the two unlocking pieces 26 are both located below the unlocking plate 27. The unlocking plate 27 is pulled downward by the wire rope 51, and the unlocking plate 27 presses the compressed end 262 of the unlocking piece 26 to rotate the unlocking piece 26, so that the blocking end 261 of the unlocking piece 26 no longer abuts against the first compression spring 216. The first compression spring 216 loses its force on the sliding seat 24, so that the clamping force of the clamping plate 25 connected to the sliding seat 24 on the angle steel at the tower end is eliminated, thereby achieving unlocking. In this embodiment, two sliding sleeves 242 are symmetrically provided on either side of the connecting plate of the sliding seat 24. The two ends of the two sliding sleeves 242 are connected to the first end plate and the second end plate, respectively. The two inner sliding rods 212 on the rotating seat 21 pass through the two sliding sleeves 242, respectively. A moving block 243 is connected to the two sliding sleeves 242. A long through-hole for the moving block 243 to pass through is provided on the bottom plate of the rotating seat 21. The clamping plate 25 is fixedly connected to the lower end of the moving block 243. In this embodiment, multiple clamping plates 25 are provided in parallel. The two outermost clamping plates 25 are each fixedly connected to a guide plate 28. The lower end of the guide plate 28 is tilted toward the first vertical plate 111 of the hook side plate 11, thereby providing guidance when hooked to the pole tower end angle steel, making it easier for the adaptor clamping mechanism 2 to be hooked onto the pole tower end angle steel. The bottom ends of the two guide plates 28 are further connected via an isolation column 281 , so that the two guide plates 28 are connected as one body to form a rigid structure, thereby enhancing its structural strength.

[0075] The working principle of the adapter clamping mechanism 2 is as follows: before the pole tower end hanging and disassembly device is hung, the adapter clamping mechanism 2 is first adjusted to the initialization state. Specifically, the unlocking piece 26 is manually rotated to make the blocking end 261 of the unlocking piece 26 abut against the first compression spring 216, and then the sliding seat 24 is slid toward the side of the hook plate 22 until the hook at the second end of the hook plate 22 is hooked on the hook hole 241 of the sliding seat 24. At this time, the first compression spring 216 is in the stored state, completing the initialization setting of the adapter clamping mechanism 2. Figure 4 When the drone carries the pole tower end hanging and disassembly device and is hung on the pole tower end angle steel, when the lifting plate 23 touches the angle steel, it will drive the hook plate 22 to move upward, and the clamping hook at the second end of the hook plate 22 will be disengaged from the clamping hole 241 of the sliding seat 24. After the sliding seat 24 loses the limiting effect of the hook plate 22, under the action of the elastic force of the first compression spring 216, the sliding seat 24 moves in the direction away from the hook plate 22, thereby driving the clamping plate 25 connected to the sliding seat 24 to move horizontally. The clamping plate 25 cooperates with the hook body 1 to clamp and fix on the pole tower end angle steel, completing the low-voltage end hanging point hanging, as shown. Figure 5 When removing the tower-end hanging and dismantling device, the drone lifts the top linkage unlocking mechanism 3, thereby pulling the wire rope 51. The wire rope 51 drives the unlocking plate 27 to move downward along the guide shaft 214, pressing the unlocking piece 26 to rotate, so that the blocking end 261 of the unlocking piece 26 no longer abuts against the first compression spring 216. The sliding seat 24 is no longer subjected to the force of the first compression spring 216, so that the clamping plate 25 connected to the sliding seat 24 loses its clamping force on the tower-end angle steel. The drone can remove the tower-end hanging and dismantling device from the tower-end angle steel by raising the height.

[0077] Specifically, if Figure 10 As shown, the top lifting member 35 includes a vertical shaft sleeve for connecting the hook 38 and a horizontal rod connected to the vertical shaft sleeve, the upper ends of the two top pins 34 are respectively connected to the two ends of the horizontal rod, and the lower ends of the two top pins 34 are respectively connected to the two top moving blocks 32 symmetrically arranged in the top shield 31. Among them, the inclined groove 321 on the top moving block 32 is located in the middle position of the top moving block 32. In order to enable the top pin 34 to be connected to the middle position of the top moving block 32, a top moving block cover plate 322 is fixedly provided on the top of the top moving block 32, and the lower end of the top pin 34 is connected to the top moving block cover plate 322. In order to make the top moving block 32 more stable when moving up and down, each top moving block 32 is slidably connected to the two top guide rods 312, and the top guide rod 312 is fixedly connected between the top plate and the bottom plate of the top shield 31, as shown in FIG. Figure 11 As shown, four top guide rods 312 are provided, and each top moving block 32 is slidably connected to two top guide rods 312 .

[0078] Furthermore, a limit block 362 is fixedly provided on the top slide bar 311 for limiting the height of the top movable cap 36. The limit block 362 is an annular structure and is sleeved on the top slide bar 311. The limit block 362 can be fixedly connected to the top slide bar 311 by a set screw. The limit block 362 limits the height of the top movable cap 36 in the following manner: when the top movable block 32 is located at the bottom plate position of the top shield 31, the top lifting plate 33 on the top movable block 32 is located below the top movable cap 36. When the pressing section 332 of the top lifting plate 33 is pressed, the end of the supporting section 331 of the top lifting plate 33 can be rotated to the outside of the top movable cap 36. In this embodiment, a linear bearing is provided between the top movable cap 36 and the top slide bar 311, and a top movable cap cover plate 361 for fixing the linear bearing is provided on the top of the top movable cap 36.

[0079] The top support 37 has a groove-shaped structure and can be fixedly connected to the two hook side plates 11 of the hook body 1 through the two groove side plates of the groove structure. The top support 37 is provided with a sheave 52 for guiding the wire rope 51. A stop pin 371 is further provided below the sheave 52 to prevent the wire rope 51 from escaping. The stop pin 371 is connected to the two hook side plates 11 of the hook body 1.

[0080] See also Figure 2 In this embodiment, two steel wires 51 are connected to the top movable cap 36. Two sheaves 52 are provided on the top support 37, one on each side of the top slide 311. Two sheaves 52 are also provided on the first and second risers 111 and 112 of the hook side panel 11. The two steel wires 51 connected to the top movable cap 36 pass through the bottom plate of the top shield 31 and the top support 37. They then wind from left and right, sequentially around the sheaves 52 on the top support 37, the two sheaves 52 on the hook body 1, and the sheaves 52 on the rotating base 21 of the adapter clamping mechanism 2, before connecting to the ends of the unlocking plate 27. By providing two steel wires 51 to simultaneously pull both ends of the unlocking plate 27, the unlocking plate 27 is better stressed, allowing the unlocking tab 26 to be more reliably pressed to unlock the lock.

[0081] The top linkage unlocking mechanism 3 works as follows: Before attaching the tower-end mounting and removal device, the top linkage unlocking mechanism 3 is first adjusted to the initialization state. Specifically, by manually pressing the pressing sections 332 of the two top lifting plates 33, the ends of the supporting sections 331 of the top lifting plates 33 move to the outside of the top moving cap 36. The top lifting member 35 is then lifted, driving the top moving block 32 upward, causing the top lifting plates 33 to move above the top moving cap 36. The top lifting plates 33 are then released, and the top lifting member 35 is simultaneously connected to the drone via the hook. When the drone carrying the pole tower end hanging and disassembly device is hung on the pole tower end angle steel and the angle steel is clamped, the drone is controlled to detach from the hook. Under the action of gravity, the top lifting member 35, the top pin shaft 34, and the top moving block 32 move downward. During the downward movement, when the top lifting plate 33 on the top moving block 32 touches the top moving cap 36, the top lifting plate 33 rotates and the top moving block 32 continues to move downward. When the top lifting plate 33 is completely moved to the bottom of the top moving cap 36, the top lifting plate 33 is reset under its own gravity. When the hanging and dismantling device at the end of the tower is removed, the drone lifts the top lifting piece 35 through the hook, driving the top moving block 32 to move upward, and the top lifting plate 33 on the top moving block 32 will drive the top moving cap 36 to move upward along the top slide bar 311, thereby pulling the wire rope 51 connected to the top moving cap 36, and then the wire rope 51 pulls the unlocking plate 27 in the adapter clamping mechanism 2 to move downward, and the unlocking plate 27 presses the unlocking piece 26 downward to rotate, and the unlocking piece 26 separates from the first compression spring 216, and the spring returns to its original state, and the clamping force on the clamping plate 25 is canceled, thereby achieving unlocking from the angle steel.

[0082] See also Figure 12The second ground wire locking mechanism 4 includes: a locking cylinder 41, a locking assembly, a ground wire clamping joint 45 and a traction rope 46; wherein, a through hole for the traction rope 46 is opened on the top of the locking cylinder 41; at least two of the locking assemblies are evenly distributed on the locking cylinder 41 along the circumference; the locking assembly includes a locking block 42, an elastic member 44 and a bayonet 43, the locking block 42 is provided with a transverse sliding hole, the elastic member 44 is provided in the sliding hole, the bayonet 43 is slidably provided in the sliding hole and is connected to the elastic member 44, and the end of the bayonet 43 extending out of the sliding hole is provided with a wedge-shaped surface inclined downward; the ground wire clamping joint 45 The upper end is connected to the traction rope 46, and the lower end of the ground wire clamp connector 45 is connected to the ground wire. The ground wire clamp connector 45 includes a conical head 451 at the upper end, a clamping shaft 452 in the middle and a connecting body 453 at the lower end. The diameter of the large end of the conical head 451 is larger than the diameter of the clamping shaft 452. The upper end of the connecting body 453 is provided with a blocking ring 4531 with a diameter larger than the clamping shaft 452. An unlocking ring 454 is provided on the clamping shaft 452 so as to slide up and down. The upper end diameter of the unlocking ring 454 is equal to the diameter of the large end of the conical head 451, and the lower end diameter of the unlocking ring 454 is equal to the diameter of the clamping shaft 452.

[0083] Specifically, the locking cylinder 41 is fixedly connected to the lower end of the hook body 1. The center of the locking cylinder 41 is a cavity for accommodating the grounding connector 45. The locking block 42 of the locking assembly is fixedly connected to the lower opening of the cavity of the locking cylinder 41. Two guide sheaves 461 are rotatably provided on the hook body 1 above the locking cylinder 41 to guide the traction rope 46. A retaining edge 14 is also provided on the outside of the guide sheaves 461 to prevent the traction rope from escaping from the guide sheaves. The traction rope 46 connected to the grounding connector 45 passes through the hole at the top of the locking cylinder 41, bypasses the two guide sheaves 461, and then passes through the outside of the hook body 1 and extends downward. It is pulled by ground personnel to complete the connection between the grounding connector 45 and the locking assembly, completing the connection of the grounding wire at the tower end. In this embodiment, three locking assemblies are provided, and the three locking assemblies are evenly distributed along the circumference of the locking cylinder 41, that is, two adjacent locking assemblies are arranged 120° apart. The elastic member 44 in the sliding hole of the locking block 42 is a compression spring. The sliding hole of the locking block 42 is a stepped hole to prevent the compression spring from dislodging from the outside of the sliding hole. The latch 43 is a stepped shaft. The two ends of the compression spring respectively abut between the sliding hole and the stepped surface of the latch 43. The end of the latch 43 located in the sliding hole can be screwed with a bolt to limit the position of the latch 43 and prevent it from dislodging from the sliding hole. The end of the latch 43 extending from the sliding hole is provided with a downwardly inclined wedge-shaped surface. When the grounding connector 45 contacts the wedge-shaped surface of the latch 43, the latch 43 is pushed into the sliding hole and compressed. When the contact point between the latch 43 and the grounding connector 45 moves from the tapered head 451 to the latch shaft 452, the diameter of the grounding connector 45 suddenly decreases. Under the action of the compression spring, the latch 43 extends and abuts the latch shaft 452, completing the locking of the grounding connector 45. When the grounding clamp connector 45 needs to be unlocked, it is necessary to use the unlocking ring 454 slidingly arranged on the clamping shaft 452, and continue to pull the grounding clamp connector 45 upward through the traction rope 46, so that the wedge-shaped surface of the clamping pin 43 contacts the unlocking ring 454 at the lower end of the clamping shaft 452, and the clamping pin 43 is pushed into the sliding hole and contracts and compresses the compression spring in the sliding hole. The unlocking ring 454 is an inverted cone structure with a large diameter at the upper end and a small diameter at the lower end. When the top end of the clamping pin 43 slides to the conical surface of the unlocking ring 454, it will push the clamping pin 43 out of the sliding hole and along the unlocking ring under the action of the compression spring. The conical surface of the ring 454 slides to the clamping shaft 452 at the lower end of the unlocking ring 454. At this time, the traction rope 46 is loosened. Under the action of the gravity of the grounding wire and the grounding clamping connector 45, the clamping pin 43 pushes the unlocking ring 454 to move to the upper end of the clamping shaft 452. Then the clamping pin 43 will slide along the conical surface of the unlocking ring 454. Since the upper end diameter of the unlocking ring 454 is equal to the large end diameter of the conical head 451, the clamping pin 43 will slide to the upper end of the unlocking ring 454 and then move to the conical head 451. The grounding clamping connector 45 continues to fall, completing the unlocking of the grounding clamping connector 45.In this embodiment, a guide sleeve is also provided on the locking cylinder 41, and the guide sleeve includes a cylindrical section inserted in the accommodating cavity of the locking cylinder 41 and a conical cylinder section located outside the accommodating cavity. The conical cylinder section can guide the ground wire card connector 45 so that it can more easily enter the accommodating cavity of the locking cylinder 41.

[0085] Specifically, the hook body 61 is a hook-shaped structure with an opening facing downward. The hook body 61 includes two side panels spaced apart and fixedly connected together by a connecting plate (not shown in the figure). The top of the opening of the hook body 61 is provided with a burr to increase the contact area with the wire; the inner side of the side panel of the hook body 61 is provided with a copper sheet to guide the current on the wire to the first ground wire locking mechanism and then to the ground wire. A guide baffle 67 is also provided on one side of the opening of the hook body 61. The lower end of the guide baffle 67 is tilted outward and is used to guide the wire when hooking. The lower end of the telescopic fixing sleeve 62 can be fixedly connected to the two side panels of the hook body 61 by welding or screw connection. The top of the hook bracket 63 is equipped with multiple hook-like structures for hooking onto the drone. The main body of the hook bracket 63 is a hollow tubular structure. The upper section of the suspension column 631 is inserted into the lower end of the hook bracket 63 and fixedly connected to the hook bracket 63. The diameter of the middle and lower sections of the suspension column 631 is smaller than that of the upper section. The middle and lower sections of the suspension column 631 slide within the telescopic fixing sleeve 62. The telescopic fixing sleeve 62 is equipped with a linear bearing to reduce frictional resistance when the suspension column 631 slides up and down within the telescopic fixing sleeve 62. The top of the telescopic fixing sleeve 62 is equipped with a suspension column cap 621 to secure the linear bearing and prevent the suspension column 631 from shifting due to rotation. The arcuate slot of the clamping contact block 65 is provided with a stepped hole. The telescopic complementary block 651 is a cylindrical structure that slides into the stepped hole. The stepped hole is provided with a complementary block spring 652, a helical compression spring. A baffle is provided at one end of the telescopic complementary block 651 located in the arcuate slot. The other end of the telescopic complementary block 651 can be prevented from falling out of the stepped hole by a screw or a retaining ring. The two ends of the complementary block spring 652 respectively abut between the stepped surface of the stepped hole and the baffle of the telescopic complementary block 651. The complementary block spring 652 is used to provide elastic force to the telescopic complementary block 651, which is used to compensate for wire gaps and accommodate wires of different sizes.

[0086] The working principle of the wire clamping mechanism 6 is as follows: the drone is equipped with the wire end hanging and detaching device via the hook bracket 63 on the top of the wire clamping mechanism 6 and moved to the position above the wire to be hung. The drone is then controlled to slowly descend and the wire clamping mechanism 6 is hung on the wire. Under the action of the wire end hanging and detaching device's own gravity, the two clamping contact blocks 65 in contact with the wire rotate. When the clamping contact blocks 65 rotate, the upper ends of the clamping contact blocks 65 push the vertical movable block 64 upward until the engaging groove at the top of the clamping contact block 65 corresponds to the engaging plate on the vertical movable block 64. At this point, the vertical movable block 64 moves downward rapidly under the action of the reset spring 66, so that the engaging plate of the vertical movable block 64 engages with the engaging groove of the clamping contact block 65. The two clamping contact blocks 65 lock and clamp the wire. If the wire end hanging and removing device's own gravity cannot achieve automatic clamping of the wire by the clamping contact block 65, the traction rope 46 on the first ground wire locking mechanism can be pulled on the ground. Under the action of the pulling force, the two clamping contact blocks 65 rotate until the clamping groove is clamped into the clamping plate of the vertical movable block 64, locking and clamping the wire. The telescopic supplementary block 651 on the clamping contact block 65 can automatically expand and contract according to the size of the wire to further compress the wire. When the operation is completed and the wire end hanging and removing device needs to be removed, the hook bracket 63 of the wire clamping mechanism 6 is pulled by the drone to move the vertical movable block 64 upward, and the two clamping contact blocks 65 are separated from the vertical movable block 64. The two clamping contact blocks 65 rotate and release the wire to complete the unlocking.

[0087] The structure of the first ground wire locking mechanism is the same as that of the second ground wire locking mechanism 4 . For details, please refer to the structure of the second ground wire locking mechanism 4 described above.

[0088] The present invention further provides a method for hanging and removing a ground wire, which is implemented using the above-mentioned hanging and removing ground wire device, and comprises the following steps:

[0089] The tower end hanging step is to hang the tower end hanging and dismantling device on the drone. The drone carries the tower end hanging and dismantling device and flies above the angle steel of the tower to be hung. The drone clamps the adapter clamping mechanism 2 in the tower end hanging and dismantling device on the angle steel of the tower by lowering the flight altitude.

[0090] Specifically, first adjust the adapter clamping mechanism 2 and the top linkage unlocking mechanism 3 to the initialization state, including rotating and moving the top lifting plate 33 in the top linkage unlocking mechanism 3 to above the top movable cap 36, rotating the unlocking piece 26 in the adapter clamping mechanism 2, so that the blocking end 261 of the unlocking piece 26 abuts against the first compression spring 216, and moving the sliding seat 24 so that the sliding seat 24 is engaged with the hook plate 22, so that the first compression spring 216 is compressed to a stored force state.

[0091] The drone is equipped with the tower-end mounting and removal device and moved to the position above the angle steel at the tower end. The drone is then controlled to slowly land. When the lifting plate 23 in the adaptive clamping mechanism 2 is pressed against the angle steel, the hook plate 22 is driven to separate from the sliding seat 24. The sliding seat 24 moves away from the hook plate 22 under the elastic force of the first compression spring 216, thereby causing the clamping plate 25 fixed to the sliding seat 24 to clamp the angle steel. After the drone is separated from the tower-end mounting and removal device, the top moving block 32 in the top linkage unlocking mechanism 3 moves to the bottom under the action of gravity, and the top lifting plate 33 on the top moving block 32 moves to below the top moving cap 36.

[0092] In the wire end hanging step, the wire end hanging and removing device is hung on the drone, and the drone carries the wire end hanging and removing device and flies above the wire to be hung. The drone clamps the wire clamping mechanism 6 in the wire end hanging and removing device on the wire by lowering the flight altitude.

[0093] Specifically, the drone is moved to the top of the wire to be hung by the hook bracket 63 on the top of the wire clamping mechanism 6, carrying the wire end hanging and detaching device. The drone is controlled to slowly land and the wire clamping mechanism 6 is hung on the wire. Under the action of the gravity of the wire end hanging and detaching device itself, the two clamping contact blocks 65 in contact with the wire rotate. When the clamping contact blocks 65 rotate, the upper ends of the clamping contact blocks 65 push the vertical movable block 64 upward until the clamping groove at the top of the clamping contact block 65 corresponds to the position of the clamping plate on the vertical movable block 64. The vertical movable block 64 then moves downward rapidly under the action of the return spring 66, so that the clamping plate of the vertical movable block 64 is engaged with the clamping groove of the clamping contact block 65. The two clamping contact blocks 65 lock and clamp the wire. If the weight of the wire end hanging and removing device itself cannot achieve automatic clamping of the wire by the clamping contact block 65, the traction rope 46 on the first ground wire locking mechanism can be pulled on the ground. Under the action of the pulling force, the two clamping contact blocks 65 rotate until the clamping groove is clamped into the clamping plate of the vertical movable block 64, locking and clamping the wire.

[0094] In the ground wire locking step, the low-voltage end and the high-voltage end of the ground wire are connected and locked by the second ground wire locking mechanism 4 and the first ground wire locking mechanism in sequence, and then the wire to be hung is operated.

[0095] Specifically, by pulling the traction rope 46 of the second ground wire locking mechanism 4 and the traction rope 46 of the first ground wire locking mechanism in sequence, the ground wire clamp connector 45 connected to the low-voltage end and the high-voltage end of the grounding wire is respectively clamped with the locking components of the second ground wire locking mechanism 4 and the first ground wire locking mechanism, thereby completing the connection between the grounding wire at the pole tower end (low-voltage hanging point) and the conductor end (high-voltage hanging point).

[0096] In the step of removing the ground wire, after the operation is completed, the high-voltage end and the low-voltage end of the ground wire are unlocked respectively through the first ground wire locking mechanism and the second ground wire locking mechanism 4, the ground wire is moved to the ground, and the ground wire is removed.

[0097] Specifically, the traction rope 46 of the first ground wire locking mechanism is pulled to make the ground wire clamp connector 45 connected to the high-voltage end of the ground wire continue to move upward, so that the wedge-shaped surface of the clamping pin 43 contacts the unlocking ring 454 at the lower end of the clamping shaft 452, and the clamping pin 43 is pushed into the sliding hole to shrink and compress the compression spring in the sliding hole. The unlocking ring 454 is an inverted cone structure with a large diameter at the upper end and a small diameter at the lower end. When the top end of the clamping pin 43 slides to the conical surface of the unlocking ring 454, it will push the clamping pin 43 out of the sliding hole under the action of the compression spring and slide along the conical surface of the unlocking ring 454 to The unlocking ring 454 is on the clamping shaft 452 at the lower end. At this time, the traction rope 46 is loosened. Under the action of the gravity of the grounding wire and the grounding clamping connector 45, the clamping pin 43 pushes the unlocking ring 454 to move to the upper end of the clamping shaft 452. Then the clamping pin 43 will slide along the conical surface of the unlocking ring 454. Since the upper end diameter of the unlocking ring 454 is equal to the large end diameter of the conical head 451, the clamping pin 43 will slide to the upper end of the unlocking ring 454 and then move to the conical head 451. The grounding clamping connector 45 continues to fall, completing the unlocking of the grounding clamping connector 45 at the high-voltage end of the grounding wire.

[0098] The steps of unlocking the low-voltage end of the ground wire by the second ground wire locking mechanism 4 refer to the steps of unlocking the high-voltage end of the ground wire by the first ground wire locking mechanism.

[0099] In the wire end removal step, the drone lifts the wire end hanging and removing device to unlock the wire clamping mechanism 6 in the wire end hanging and removing device and separate it from the wire. The drone carries the wire end hanging and removing device to the ground.

[0100] Specifically, the hook bracket 63 of the wire clamping mechanism 6 is pulled up by the drone to move the vertical movable block 64 upward, and the two clamping contact blocks 65 are separated from the vertical movable block 64. The two clamping contact blocks 65 rotate and release the wire to complete the unlocking.

[0101] The tower end dismantling step is to lift the top linkage unlocking mechanism 3 in the tower end hanging and dismantling device by the drone, so that the adapter clamping mechanism 2 in the tower end hanging and dismantling device is unlocked and separated from the angle steel of the tower, and the drone carries the tower end hanging and dismantling device to the ground.

[0102] Specifically, the drone lifts the top lifting piece 35 of the top linkage unlocking mechanism 3 by the hook and moves upward, driving the top moving block 32 to move upward, and the top lifting plate 33 on the top moving block 32 lifts the top moving cap 36 on the top slide rod 311 to move upward, thereby pulling the wire rope 51 connected to the top moving cap 36, and then the wire rope 51 pulls the unlocking plate 27 to move downward along the guide shaft 214, and the unlocking plate 27 presses the unlocking piece 26 downward to rotate, so that the blocking end 261 of the unlocking piece 26 no longer abuts against the first compression spring 216, and the sliding seat 24 is no longer subjected to the force of the first compression spring 216, so that the clamping plate 25 connected to the sliding seat 24 loses the clamping force on the pole tower end angle steel, thereby achieving unlocking with the angle steel. The drone can remove the pole tower end hanging and dismantling device from the pole tower end angle steel by raising the height.

[0103] The present invention provides a grounding wire hanging and removing device and method, wherein the grounding wire hanging and removing device includes a conductor end hanging and removing device and a pole tower end hanging and removing device. The pole tower end hanging and removing device and the conductor end hanging and removing device are carried by an unmanned aerial vehicle (UAV) to complete the hanging of the low-voltage end hanging point and the high-voltage end hanging point in sequence. The adaptive clamping mechanism of the pole tower end hanging and removing device and the conductor clamping mechanism of the conductor end hanging and removing device can respectively realize adaptive clamping and reliable contact of the pole tower end angle steel and the conductor, thereby effectively avoiding the risk of intermittent disconnection of the grounding wire.
