Description

[0002] Before carrying out maintenance work on a power-off line or equipment, a grounding wire needs to be installed, which can prevent induced voltage from causing injury and effectively avoid personal injury caused by accidental power transmission. In the traditional installation of grounding wire, the operator carries the grounding wire to the tower and performs the operation layer by layer and phase by phase, and then removes it in reverse order. The traditional installation of grounding wire is labor-intensive and has the risk of induced voltage injury and high-altitude falling. With the wide application of unmanned aerial vehicles and robots in the process of transmission line maintenance, the combination of unmanned aerial vehicles and grounding wire installation technology can effectively improve the efficiency of maintenance and ensure the safety of operation.

[0055] Referring toFigure 3 In this embodiment, the hook body 1 includes two hook side plates 11 spaced at a predetermined distance and arranged in parallel, and several support blocks 12 fixedly connected between the two hook side plates 11. A guide plate 13 inclined outwards is provided on one side of the open end of the hook body 1 to increase the opening width of the hook body 1 and better guide the hook body 1 to fall into place at the pole end. In this embodiment, the anti-fall mechanism 3, clamping mechanism 2, linkage control mechanism 4, and ground wire locking mechanism 5 are all located between the two hook side plates 11. When assembling the device, the support blocks 12 are first welded and fixed to one hook side plate 11 according to the designed position, and the anti-fall mechanism 3, clamping mechanism 2, linkage control mechanism 4, and ground wire locking mechanism 5 are then installed and fixed. The other hook side plate 11 is then sealed and welded to ensure that the linkages of each mechanism are flexible and without jamming, thereby completing the overall structural assembly of the device. In this embodiment, several weight-reducing holes are provided on the hook side plates 11 to reduce the overall weight of the device and reduce the load when the drone is lifted.

[0056] See Figure 7The clamping mechanism 2 includes two lifting pins 22, a lifting plate 27, a top bearing 272, and a bent plate 21. The two lifting pins 22 are vertically positioned on either side of the upper part of the opening of the hook body 1. An upper lifting support plate 25 and a lower lifting support plate 26 are fixed to the upper and lower ends of each lifting pin 22, respectively, and are fixed to the hook body 1. The two ends of the lifting plate 27 are slidably connected to the lifting pins 22, and the lifting plate 27 can move along the... The lifting pin 22 slides up and down; a first compression spring 23 is provided between the upper lifting support plate 25 and the end of the lifting plate 27; the top bearing 272 is rotatably connected to the top of the lifting plate 27; the curved plate 21 includes a sickle-shaped clamping section 211 and a driving section 212 connected to one end of the clamping section 211, the middle part of the driving section 212 is rotatably connected to the upper end of the hook body 1 through a rotating pin 28, and the end of the driving section 212 away from the clamping section 211 abuts against the top bearing 272. In the initial state, the lifting plate 27 is located at the lower end of the lifting pin 22 under the action of the first compression spring 23, that is, the two ends of the lifting plate 27 abut against the lower lifting support plate 26. When the UAV lifts the device and hangs it on the tower end, the lifting plate 27 is lifted under the action of the device's own weight, which compresses the first compression spring 23. When the lifting plate 27 is lifted, the top bearing 272 on the lifting plate 27 pushes the drive section 212 of the bending plate 21 to rotate around the rotating pin 28, thereby driving the clamping end of the bending plate 21 to rotate, so that the clamping end of the bending plate 21 is clamped on the crossarm or the angle steel structure of the tower top. When the UAV lifts the device again, the lifting plate 27 moves downward along the lifting pin 22 under the action of the first compression spring 23 to reset, so that the bending plate 21 is reset and released from the clamping state of the tower end. In this embodiment, a first linear bearing 24 is provided at each end of the lifting plate 27. The two ends of the lifting plate 27 are slidably connected to the lifting pin 22 through the first linear bearing 24, thereby reducing the frictional resistance of the lifting plate 27 when sliding up and down on the lifting pin 22. Furthermore, a contact copper plate 271 is fixedly provided at the bottom of the lifting plate 27. By providing a contact copper plate 271 at the bottom of the lifting plate 27, the contact area between the hanging device and the steel structure of the pole is increased when the hanging device is hung on the pole, thereby enhancing the conductivity.

[0057] See Figure 4The fall arrest mechanism 3 includes a protective sleeve base, a rotating cylinder 32, an upper and lower sliding shaft 33, a second compression spring 36, a deflecting shaft 34, and a fall arresting rod 35. The protective sleeve base includes a cylindrical protective sleeve 31, and an upper support plate 37 and a lower support plate 38 fixedly connected to the upper and lower ends of the protective sleeve 31. The rotating cylinder 32 has a cylindrical structure and is rotatably connected to the protective sleeve 31. The upper and lower sliding shaft 33 passes through the rotating cylinder 32 and is slidably connected to the protective sleeve base. The upper end of the second compression spring 36 is fixedly connected to the hook body 1, and the lower end of the second compression spring 36 is fixedly connected to the top end of the upper and lower sliding shaft 33. One end of the deflecting shaft 34 is fixedly mounted on the upper and lower sliding shaft 33. The rotating cylinder 32 is provided with a spiral guide groove 321 (e.g., ...). Figure 5 As shown, the other end of the actuating shaft 34 is inserted into the spiral guide groove 321; one end of the anti-fall rod 35 is fixed on the rotating cylinder 32, and the other end of the anti-fall rod 35 extends out of the protective cylinder 31 through the guide groove 311 on the protective cylinder 31; the lower end of the wire rope 7 is connected to the upper and lower sliding shaft 33. When the associated control mechanism 4 drives the upper and lower sliding shaft 33 to move up or down through the wire rope 7, the actuating shaft 34 actuates the rotating cylinder 32 to rotate forward or in the opposite direction, thereby driving the anti-fall rod 35 to swing forward or in the opposite direction in the horizontal direction to unlock or lock.

[0058] Specifically, the upper support plate 37 and the lower support plate 38 support and guide the upper and lower sliding shaft 33 during sliding. The upper support plate 37 and the lower support plate 38 can be welded and fixed to the hook body 1. The upper and lower sliding shaft 33 can be set with a non-circular cross section so that it will not rotate during sliding. Alternatively, a guide rail can be provided on the outer wall of the upper and lower sliding shaft 33, and the upper support plate 37 and the lower support plate 38 can be provided with rail grooves that match the guide rails, thereby restricting the upper and lower sliding shaft 33 from rotating during sliding.

The initial state of the fall arrest mechanism 3 is that the fall arrest rod 35 is horizontally locked at the lower end of the opening of the hook body 1. When the associated control mechanism 4 controls the wire rope 7 to lift the upper and lower sliding shafts 33 of the fall arrest mechanism 3, the upper and lower sliding shafts 33 slide upward to compress the second compression spring 36. The actuating shaft 34 on the upper and lower sliding shafts 33 moves along the spiral guide groove 321 of the rotating cylinder 32, thereby driving the rotating cylinder 32 to rotate. The rotation of the rotating cylinder 32 drives the fall arrest rod 35 connected to the rotating cylinder 32 to rotate, so that the fall arrest rod 35 swings horizontally from the lower end of the opening of the hook body 1 to the unlocked state, thereby making the opening of the hook body 1 open, so that the device can be hung on the pole end or separated from the pole end. When the associated control mechanism 4 releases the wire rope 7, the upper and lower sliding shafts move downward under the elastic force of the second compression spring 36 to return to the initial state, thereby restoring the fall arrest rod 35 to the initial locked state at the lower end of the opening of the hook body 1. In this embodiment, the rotation range of the fall arrestor 35 is 90°, the angle of the guide groove 311 on the protective cylinder 31 is 90 degrees, and an opening groove for the fall arrestor 35 to swing is also provided on the hook side plate 11 on one side of the hook body 1. The included angle between the starting end and the ending end of the spiral guide groove 321 is also 90 degrees, and the height of the spiral guide groove 321 is determined according to the vertical sliding range of the upper and lower sliding shaft 33. In this embodiment, a rotating bearing is provided between the rotating cylinder 32 and the protective cylinder 31 to reduce the friction during the rotation of the rotating cylinder 32 and to provide support for the rotating cylinder 32.

When the underground locking connector touches the wedge-shaped surface of the locking pin 53, it pushes the locking pin 53 to retract into the sliding hole and compresses the compression spring in the sliding hole. When the contact part between the locking pin 53 and the grounding locking connector 55 moves from the conical head 551 to the locking shaft 552, the diameter of the grounding locking connector 55 suddenly decreases. Under the action of the compression spring, the locking pin 53 extends out and abuts against the locking shaft 552, thus completing the locking of the grounding locking connector 55. When it is necessary to unlock the underground clamp, the unlocking ring 554, which is slidably set on the clamping shaft 552, is used to pull the ground wire clamp 55 upward by the traction rope 56. This causes the wedge-shaped surface of the locking pin 53 to contact the unlocking ring 554 at the lower end of the clamping shaft 552. The locking pin 53 is pushed into the sliding hole and retracts, compressing the compression spring in the sliding hole. The unlocking ring 554 is an inverted conical structure with a larger diameter at the upper end and a smaller diameter at the lower end. When the top of the locking pin 53 slides to the conical surface of the unlocking ring 554, it will be pushed out of the sliding hole by the compression spring and along the unlocking ring 554. The conical surface of ring 554 slides onto the locking shaft 552 at the lower end of the unlocking ring 554. At this time, the traction rope 56 is released. Under the gravity of the grounding wire and the underground locking connector, the locking pin 53 pushes the unlocking ring 554 to the upper end of the locking shaft 552. Then, the locking pin 53 will slide along the conical surface of the unlocking ring 554. Since the diameter of the upper end of the unlocking ring 554 is equal to the diameter of the large end of the conical head 551, after the locking pin 53 slides to the upper end of the unlocking ring 554, it will then move onto the conical head 551. The grounding connector 55 continues to fall, completing the unlocking of the grounding connector 55. In this embodiment, the locking cylinder 51 is also provided with a guide sleeve. The guide sleeve includes a cylindrical section inserted into the receiving cavity of the locking cylinder 51 and a conical section located outside the receiving cavity. The conical section can guide the grounding connector 55, making it easier for it to enter the receiving cavity of the locking cylinder 51.
