Description

Technical Field

[0001] The invention relates to the technical field of power supply obstacle removal, and in particular to a high-altitude tethering device. Background Art

[0002] As the scale and coverage of the power grid continue to expand, tree barriers in transmission line channels and protected areas have become prominent, seriously affecting the stable operation of power supply devices. In order to reduce the risk of tree barrier hazards to the safe operation of transmission lines and ensure the reliability of power supply to the power grid, workers need to regularly clear tree barriers in the line channels under their jurisdiction. At present, the most direct way to clear tree barriers is to cut down the entire tree, especially for super-tall trees. During the tree felling process, rope traction is usually used to accurately control the direction of the tree's fall to ensure the safety of workers and power facilities. However, when working with ropes, workers need to climb trees or use long ladders to operate at high altitudes, which poses a safety hazard of falling from high altitudes and accidental electric shock. Summary of the invention

[0003] In order to overcome the deficiencies in the prior art, the present invention provides a high-altitude tethering device, which has the advantage of improving safety without the need for climbing.

[0004] In order to achieve the above object, the present invention adopts the following technical solution:

[0005] A high-altitude tethering device comprises an insulating rod, a tethering rope head connected to the top of the insulating rod and a traction rope; the tethering rope head comprises a tethering rope seat, a tethering rope locking head and a tethering rope driving member; a hook rope lock seat is arranged on the tethering rope seat; the tethering rope locking head has a locking head seat, and a first hook and a second hook are inserted and hung together; a third hook is inserted on the hook rope lock seat; one end of the traction rope passes through the third hook and is fixed on the second hook; the tethering rope driving member is used to drive the tethering rope locking head away from or close to the hook rope lock seat; when the tethering rope locking head is close to the hook rope lock seat, the first hook is hooked on the third hook.

[0006] By adopting the above technical scheme, when the traction rope is connected to the tying rope head, the third hook is inserted into the hook rope lock seat, the first hook and the second hook hooked together are inserted into the lock head seat, and then the traction rope passes through the third hook and the final end is fixed on the second hook hooked with the first hook, which is convenient for connecting the traction rope with the tying rope head; when tying the rope, the operator moves the tying rope head close to the branch to which the rope is required to be tied through the insulating rod, and then the tying rope driving member drives the tying rope lock head close to the hook rope lock seat. During this process, the end of the traction rope is pulled by the second hook on the lock head seat to move around the branch until the first hook hooked with the second hook and the third hook through which the traction rope passes are hooked, so that one end of the traction rope is put on the branch through the second hook, the first hook and the third hook. During this process, there is no need to climb trees or use a long ladder for high-altitude operations, which improves safety.

[0007] Optionally, the first hanging buckle, the second hanging buckle and the third hanging buckle have the same structure, and all have a hanging notch and a swinging opening and closing member with one end elastically hinged to the wall of the hanging notch; when the swinging opening and closing member is subjected to a thrust, the swinging opening and closing member swings to open the hanging notch; when the tether rope lock head is close to the hook rope lock seat, the swinging opening and closing members of the first hanging buckle and the third hanging buckle press against each other and apply force.

[0008] By adopting the above technical solution, when the tether rope lock head is close to the hook rope lock seat, the swing opening and closing parts of the first hook and the third hook are pressed against each other and exert force, so that a pair of swing opening and closing parts complete avoidance and return to their positions while the moving directions of the first hook and the third hook remain unchanged, thereby realizing the hooking of the first hook and the third hook, and improving the hooking completion rate of the first hook and the third hook.

[0009] Optionally, a first insertion groove and a first avoidance groove which are perpendicular to each other are formed on the end surface of the lock seat facing the hook rope lock seat; a second insertion groove and a second avoidance groove which are perpendicular to each other are formed on the end surface of the hook rope lock seat facing the lock seat; the first hook is inserted into the first insertion groove, the first avoidance groove faces the swing opening and closing part of the first hook and avoids the third hook; the third hook is inserted into the second insertion groove, the second avoidance groove faces the swing opening and closing part of the third hook and avoids the first hook.

[0010] By adopting the above technical solution, the first hook and the second hook are first hooked together, and then the first hook is inserted into the first insertion slot with its swing opening and closing piece facing outward, and the third hook is inserted into the second insertion slot with its swing opening and closing piece facing outward. When the lock head seat is close to the hook rope lock seat, the second avoidance groove avoids the first hook and the first avoidance groove avoids the third hook, so that the swing opening and closing pieces of the first hook and the third hook will not interfere with each other during the process of applying force to each other, thereby ensuring the smooth hooking of the first hook and the third hook.

[0011] Optionally, a traction rope placement seat is provided on the rope tying seat; a plurality of clamping blocks are formed on the traction rope placement seat; and a clamping gap for the traction rope to be clamped into is provided between the clamping block and the rope tying seat.

[0012] By adopting the above technical solution, the traction rope can be inserted into the clamping gap between the block and the rope seat, so that the traction rope is distributed along the rope seat, reducing the possibility of the rope head accidentally getting caught on other branches when approaching the target branch.

[0013] Optionally, the tether seat has an arc-shaped hook portion; the tether lock head and the hook lock seat are located on the opening side of the tether seat; and the tether lock head moves circumferentially around the rotation center axis of the hook portion.

[0014] By adopting the above technical solution, the arc-shaped hook portion can allow branches to enter its opening, which is conducive to the subsequent traction rope around the branch. When the rope lock moves circumferentially around the rotation center axis of the hook portion, it is more conducive to the traction rope around the branch, thereby improving the success rate of tying the rope.

[0015] Optionally, the tether lock includes an arc guide portion and a driving arc rack; the arc guide portion is connected to the lock seat; the driving arc rack, the arc guide portion and the hook portion are coaxially arranged; an arc limiting structure is arranged between the driving arc rack and the arc guide portion, and the driving arc rack and the arc guide portion move in an arc at a fixed angle relative to each other; an extended arc segment is arranged at one end of the driving arc rack toward the lock seat; an arc guide groove for inserting the extended arc segment is formed on the hook lock seat; the tether drive component includes a tether drive motor and a driving gear; the tether drive motor drives the driving gear to rotate; and the driving gear is meshed with the driving arc rack.

[0016] By adopting the above technical solution, when the lock head seat is close to the hook rope lock seat, the rope driving motor drives the active gear to rotate, and drives the driving arc rack meshing with the active gear to move in an arc shape. Since the driving arc rack and the arc guide part move in an arc shape at a fixed angle relative to each other, when the driving arc rack moves in an arc shape at a certain angle, the arc guide part will be driven by the driving arc rack to move in an arc shape. In this process, the extended arc segment of the driving arc rack extends out and exceeds the lock head seat. In this way, during the arc movement of the tether rope lock head, the extended arc segment will be inserted first. In this way, due to the guiding effect of the extended arc segment and the arc guide groove, the force exerted by the swinging opening and closing parts of the first hook and the third hook during the mutual force will not cause the lock head seat to shift, thereby improving the hooking efficiency of the first hook and the third hook; and in the initial state, the extended arc segment does not exceed the lock head seat, so that the overall opening of the tying rope head is maximized, which makes it more convenient for branches to enter the opening of the tying rope head, thereby facilitating subsequent tying of ropes.

[0017] Optionally, one of the driving arc rack and the arc guide portion has an arc groove-shaped limiting guide groove, and the other has a limiting guide bar that cooperates with the limiting guide groove; the angle of the limiting guide groove is greater than the angle of the limiting guide bar and both ends are sealed.

[0018] By adopting the above technical solution, since the angle of the limiting guide groove is greater than the angle of the limiting guide bar and the two ends are sealed, the limiting guide bar can move in the arc of the limiting guide groove. When the driving arc rack moves in the arc, the driving arc rack first moves a certain angle before the end of the limiting guide bar abuts against the end of the limiting guide groove, so that the arc guide part moves together with the limiting guide bar, which is conducive to the extension and retraction of the extended arc segment.

[0019] Optionally, a monitoring device is provided on the tether seat; the monitoring device is used to observe the connection status of the first hook and the third hook.

[0020] By adopting the above technical solution, when it is unclear whether the first hook and the third hook have been hooked, continuing to implement the subsequent steps, that is, separating the tying rope head and the traction rope and pulling the traction rope, may result in tying failure. In this case, the tying rope can only be performed after the tying rope head and the traction rope are restored to their original state, which greatly increases the tying time.

[0021] Optionally, the tether drive is controlled by a remote controller.

[0022] By adopting the above technical solution, the operator can control every step of the tether on the ground, which greatly improves the convenience of operation.

[0023] Optionally, the insulating rod is detachably connected to the tether head.

[0024] By adopting the above technical solution, the insulating rod and the tying rope head can be detachably connected, which is convenient for storage and transportation. BRIEF DESCRIPTION OF THE DRAWINGS

[0054] When working, refer to Fig. 9First, the traction rope 200 is connected to the tether head 20: the third hook 90 is inserted into the hook rope lock seat 31, and the first hook 70 and the second hook 80 hooked together are inserted into the lock head seat 61, and then the traction rope 200 passes through the third hook 90 and the final end is fixed on the second hook 80 hooked with the first hook 70; then the traction rope 200 is tied to the target branch 300: the lock head seat 61 moves in an arc close to the hook rope lock seat 31, so that the swing opening and closing piece 72 of the first hook 70 and the swing opening and closing piece 72 of the third hook 90 are vertically abutted. By applying force, the first hook 70 and the third hook 90 are hooked by avoiding each other, so that the end of the traction rope 200 is hooked on the traction rope 200 through the second hook 80, the first hook 70 and the third hook 90 to form a rope loop that surrounds the target branch 300; then the lock seat 61 moves back in an arc, during which the first hook 70 and the second hook 80 are separated from the lock seat 61, and the third hook 90 is separated from the hook rope lock seat 31; then the rope head 20 is removed; finally, the traction rope 200 is tightened so that the traction rope 200 is fastened to the target branch 300.

[0055] Embodiment 2: The difference between Embodiment 2 and Embodiment 1 is: Figure 1 and Fig.10 The tethering seat 30 is provided with a traction rope 200 placement seat 40; a plurality of clamping blocks 41 are formed on the traction rope 200 placement seat 40; a clamping gap for the traction rope 200 to be clamped is provided between the clamping block 41 and the tethering seat 30; in this way, after the traction rope 200 passes through the third hook 90, it is connected to the second hook 80, and the traction rope 200 is partially clamped in the clamping gap between the third hook 90 and the second hook 80, so as to prevent the traction rope 200 between the third hook 90 and the second hook 80 from accidentally being caught on branches other than the target branch 300. In order to facilitate the disassembly and assembly of the traction rope placement seat 40, the traction rope placement seat 40 is connected to the tethering seat 30 by screws.

[0057] In order to realize the driving arc rack 63 and the arc guide part 62 to move relative to each other at a fixed angle, refer to Figure 6A coaxially arranged limiting guide bar 632 is formed on the driving arc rack 63 near the arc guide part 62, and a limiting guide groove 621 is formed on the arc guide part 62 for the arc sliding of the limiting guide bar 632. The angle of the limiting guide groove 621 is greater than the angle of the limiting guide bar 632 and both ends are sealed. When the driving arc rack 63 is driven by the active gear 100 to move in an arc at a certain angle, the end of the moving side of the driving arc rack 63 will abut against the end of the corresponding side of the limiting guide groove 621, thereby driving the arc guide part 62 to move in an arc, thereby completing the extension and retraction of the extended arc segment 631. When the extended arc segment 631 is extended, the extended arc segment 631 will extend into the arc guide groove 312 of the hook rope lock seat 31 before the first hook 70 and the third hook 90 contact, thereby increasing the connection strength of the arc guide part 62, the driving arc rack 63 and the hook rope lock seat 31, thereby avoiding the arc guide part 62 from deviating during the arc movement, thereby affecting the subsequent hooking of the first hook 70 and the third hook 90.

[0060] Embodiment 4: The difference between Embodiment 4 and Embodiment 1 is: Figure 1 A monitoring device is provided on the tether seat 30; the monitoring device includes a monitoring camera 50; the power supply on the tether seat 30 supplies power to the monitoring camera 50; the monitoring camera 50 is connected to the tether seat 30 through a universal tube 51. Because the universal tube 51 is both flexible and strong enough, the monitoring camera 50 can be facing any position, and the monitoring camera 50 is facing the hooking position of the first hook 70 and the third hook 90. ​​In this way, the hooking status of the first hook 70 and the third hook 90 can be observed in real time through the monitoring camera 50 and the mobile phone APP.

[0061] Embodiment 5: The difference between Embodiment 5 and Embodiment 1 is: Figure 5, a connecting rod 32 is formed at the bottom of the tether seat 30, a connecting vertical plane is formed on the connecting rod 32, and a connecting vertical plane is also formed on the top of the insulating rod 10; a connecting through hole is formed on the connecting vertical plane; when the insulating rod 10 is connected to the connecting rod 32, the connecting vertical planes of the connecting rod 32 and the insulating rod 10 are against each other and the connecting through holes of the two are opposite, and then the bolt passes through a pair of connecting through holes to connect the insulating rod 10 and the connecting rod 32. In order to prevent the two from rotating relative to each other, a plurality of fan-shaped connecting limit blocks 321 uniformly distributed along the circumference of the connecting through holes are formed on the connecting vertical planes of the connecting rod 32 and the insulating rod 10, and the connecting limit blocks 321 of the connecting rod 32 are inserted between a pair of adjacent connecting limit blocks 321 of the insulating rod 10. In this way, the tether seat 30 and the insulating rod 10 are easy to disassemble and assemble, and are easy to store and transport. In order to make storage and transportation more convenient, the insulating rod 10 can be made into a telescopic rod.

[0062] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention.
