Description

Technical Field

[0001] This invention relates to the field of power supply obstacle removal technology, and in particular to a high-altitude rope-tying device. Background Technology

[0002] With the continuous expansion of the power grid's scale and coverage area, the conflict between tree obstructions and power transmission line corridors and protected areas has become prominent, seriously affecting the stable operation of power supply equipment. To reduce the risks posed by tree obstructions to the safe operation of transmission lines and ensure the reliability of power supply, staff need to regularly clear tree obstructions within the corridors under their jurisdiction. Currently, the most direct method for clearing tree obstructions is to fell entire trees, especially excessively tall ones. During tree felling, rope traction is typically used to accurately control the tree's direction of fall, ensuring the safety of workers and power facilities. However, rope traction work requires workers to climb trees or use long ladders for high-altitude operations, posing safety hazards such as falls from heights and accidental electric shock. Summary of the Invention

[0003] To overcome the shortcomings of the prior art, the present invention provides a high-altitude rope-tying device, which has the advantage of improving safety by eliminating the need for climbing.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A high-altitude rope-tying device includes an insulating rod, a rope-tying head connected to the top of the insulating rod, and a traction rope. The rope-tying head includes a rope-tying seat, a rope-tying lock head, and a rope-tying drive. A hook-lock seat is provided on the rope-tying seat. The rope-tying lock head has a lock head seat and a first hook and a second hook that are hooked together. A third hook is inserted on the hook-lock seat. One end of the traction rope passes through the third hook and is fixed to the second hook. The rope-tying drive is used to drive the rope-tying lock head away from or towards the hook-lock seat. When the rope-tying lock head approaches the hook-lock seat, the first hook hooks onto the third hook.

[0006] By adopting the above technical solution, when the traction rope is connected to the tethering head, the third hook is inserted into the hook lock seat, and the first and second hooks, which are hooked together, are inserted into the lock head seat. Then, the traction rope passes through the third hook and its final end is fixed to the second hook that is hooked with the first hook. This facilitates the connection between the traction rope and the tethering head. When tying the rope, the operator uses an insulating rod to bring the tethering head close to the branch where the rope needs to be tied. Then, the tying drive moves the tethering lock head close to the hook lock seat. During this process, the end of the traction rope is pulled around the branch by the second hook on the lock head seat until the first hook that is hooked with the second hook and the third hook through which the traction rope passes hook together. In this way, one end of the traction rope is looped onto 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 long ladders for high-altitude operations, thus improving safety.

[0007] Optionally, the first hook, the second hook, and the third hook have the same structure, each having a hanging notch and a swing opening / closing member that is elastically hinged at one end to the wall of the hanging notch; when the swing opening / closing member is pushed, it swings open the hanging notch; when the rope lock head approaches the hook lock seat, the swing opening / closing members of the first hook and the third hook abut against each other and exert force.

[0008] By adopting the above technical solution, when the rope lock head approaches the hook lock seat, the swing opening and closing parts of the first hook and the third hook abut against each other and exert force. Thus, the pair of swing opening and closing parts complete the avoidance and return to their original positions while the movement direction of the first hook and the third hook remains 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, the end face of the lock head seat facing the hook lock seat is formed with a first insertion groove and a first clearance groove that are perpendicular to each other; the end face of the hook lock seat facing the lock head seat is formed with a second insertion groove and a second clearance groove that are perpendicular to each other; the first hook is inserted into the first insertion groove, the first clearance groove is directly opposite 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 clearance groove is directly opposite 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. Then, the first hook is inserted into the first insertion slot with its swing opening and closing part facing outward. The third hook is inserted into the second insertion slot with its swing opening and closing part facing outward. When the lock head seat approaches the hook rope lock seat, the second clearance slot avoids the first hook and the first clearance slot avoids the third hook. In this way, the swing opening and closing parts of the first hook and the third hook will not interfere with each other during the mutual force application, ensuring that the first hook and the third hook are successfully hooked together.

[0011] Optionally, the rope-tying seat is provided with a traction rope mounting seat; the traction rope mounting seat is formed with a plurality of locking blocks; and a locking gap is provided between the locking blocks and the rope-tying seat for the traction rope to be locked in.

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

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

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

[0015] Optionally, the rope-tying lock head includes an arc-shaped guide portion and a driving arc-shaped rack; the arc-shaped guide portion is connected to the lock head seat; the driving arc-shaped rack, the arc-shaped guide portion, and the hook portion are coaxially arranged; an arc-shaped limiting structure is provided between the driving arc-shaped rack and the arc-shaped guide portion, and the driving arc-shaped rack and the arc-shaped guide portion move relative to each other at a certain angle arc; an extended arc segment is provided at one end of the driving arc-shaped rack facing the lock head seat; an arc-shaped guide groove is formed on the hook lock seat for the extended arc segment to be inserted; the rope-tying drive component includes a rope-tying drive motor and a drive gear; the rope-tying drive motor drives the drive gear to rotate; the drive gear meshes with the driving arc-shaped rack.

[0016] By adopting the above technical solution, when the lock head seat approaches the hook rope lock seat, the rope-tying drive motor drives the drive gear to rotate, which in turn drives the drive arc rack meshing with the drive gear to move in an arc. Since the drive arc rack moves relative to the arc guide at a certain angle, the arc guide will only be driven to move in an arc along with the drive arc rack after the drive arc rack has moved a certain angle. During this process, the extended arc segment of the drive arc rack extends beyond the lock head seat. Thus, during the arc movement of the rope lock head, the extended arc segment will first insert... Once inserted into the arc guide groove of the hook lock seat, the swinging opening and closing parts of the first and third hooks will exert force on each other to avoid each other. 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 and third hooks during the process will not cause the lock head seat to shift, thereby improving the hooking efficiency of the first and third hooks. In the initial state, the extended arc segment does not exceed the lock head seat, making the overall opening of the rope head the largest, which makes it easier for branches to enter the opening of the rope head, thus facilitating subsequent rope tying.

[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 both 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 moves at a certain angle first, and then the end of the limiting guide bar will abut against the end of the limiting guide groove. Thus, the arc guide part will move together with the limiting guide bar as it continues to move. This is beneficial for realizing the extension and retraction of the extended arc segment.

[0019] Optionally, a monitoring device is provided on the rope-tying 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, if it is unclear whether the first and third hooks have been successfully hooked, and the subsequent steps are carried out, namely separating the rope end and the traction rope and pulling the traction rope, the rope will fail to be tied. In this case, the rope end and the traction rope must be removed and restored to their original state before tying the rope again, which greatly increases the rope tying time.

[0021] Optionally, the tethering drive is controlled by a remote control.

[0022] By adopting the above technical solution, operators can control every step of the rope-tying process from the ground, greatly improving operational convenience.

[0023] Optionally, the insulating rod is detachably connected to the rope end.

[0024] By adopting the above technical solution, the insulating rod and the rope end can be detachably connected, which facilitates storage and transportation. Attached Figure Description

[0048] The following is in conjunction with the appendix Figure 1-10 The present invention will be described in further detail below.

[0049] Example 1: A high-altitude rope-tying device is disclosed, with reference to... Figure 1 The system includes an insulating rod 10, a rope-tying head 20 connected to the top of the insulating rod 10, and a traction rope 200. The rope-tying head 20 includes a rope-tying seat 30, a rope-tying lock head 60, and a rope-tying drive component. The end of the rope-tying seat 30 away from the insulating rod 10 is formed into an arc-shaped hook portion, and the opening of the hook portion allows branches to enter for easy subsequent rope tying. An arc-shaped hook rope lock seat 31 is formed on the lower side wall of the opening side of the rope-tying seat 30. The rope lock head 60 is arc-shaped and telescopically disposed on the upper side wall of the opening side of the rope-tying seat 30. The arc-shaped moving path of the rope lock head 60, the hook portion, and the hook rope lock seat 31 are coaxially arranged. The rope-tying drive is mounted on the rope-tying seat 30 and drives the rope-tying lock head 60 to move in an arc away from or towards the hook rope lock seat 31. To facilitate the connection of the traction rope 200, a first hook 70 and a second hook 80 are inserted and hooked together on the end face of the rope-tying lock head 60 near the hook rope lock seat 31. A third hook 90 is inserted on the end face of the hook rope lock seat 31 near the rope-tying lock head 60. One end of the traction rope 200 passes through the third hook 90 and is fixed to the second hook 80. As the rope-tying lock head 60 moves closer to the hook rope lock seat 31, the first hook 70 hooks onto the third hook 90. ​​In other embodiments, the rope-tying seat 30 may not have an opening for the branch to enter, the rope-tying lock head 60 may not move in an arc, and the hook rope lock seat 31 may not be arc-shaped. As long as the rope-tying lock head 60, the hook rope lock seat 31, and the rope-tying seat 30 can ultimately surround the branch, this embodiment is the optimal choice.

[0050] refer to Figure 2 The first hook 70, the second hook 80, and the third hook 90 have the same structure. Each of the three hooks includes a ring-shaped hook body 71 and a swing opening / closing member 72. The hook body 71 is formed into a small end 711 and a large end 712 at both ends, wherein the diameter of the large end 712 is larger than the diameter of the small end 711. One end of the hook body 71 is formed with a hanging notch 710. The hanging notch 710 is located between the small end 711 and the large end 712. One end of the swing opening / closing member 72 is elastically hinged to the wall of the hanging notch 710. When the swing opening / closing member 72 is not subjected to force, the swing opening / closing member 72 closes the hanging notch 710. When the swing opening / closing member 72 is subjected to a pushing force, the swing opening / closing member 72 swings inward to open the hanging notch 710.

[0051] refer to Figures 5-8The rope-tying lock head 60 includes a lock head seat 61, an arc-shaped guide portion 62, and a driving arc-shaped rack 63; the arc-shaped guide portion 62 and the driving arc-shaped rack 63 are coaxially arranged with the hook portion; the hook portion is formed with a telescopic arc groove 300 for the arc-shaped guide portion 62 to move in an arc; the lock head seat 61 is fixed to one end of the arc-shaped guide portion 62 away from the telescopic arc groove 300; the driving arc-shaped rack 63 is connected to the arc-shaped guide portion 62; the rope-tying drive component includes a rope-tying drive motor and a drive gear 100; the rope-tying drive motor is fixed on the rope-tying seat 30; the rope-tying drive motor drives the drive gear 100 to rotate; the drive gear 100 meshes with the driving arc-shaped rack 63; for easy operation on the ground, the rope-tying drive motor can be controlled by a remote control; the rope-tying seat 30 is provided with a power supply, which supplies power to the rope-tying drive motor, and the power supply can be repeatedly charged.

[0052] refer to Figure 3 The lock head seat 61 has a first insertion groove 610, a third insertion groove 612 and a first clearance groove 611 formed on the end face facing the hook lock seat 31; the first insertion groove 610 is perpendicular to the third insertion groove 612 and the first clearance groove 611 respectively; the first hook 70 is inserted into the first insertion groove 610, the swing opening and closing part 72 of the first hook 70 is away from the first insertion groove 610 and the first clearance groove 611 is directly opposite the swing opening and closing part 72 of the first hook 70; the second hook 80 is inserted into the third insertion groove 612, the swing opening and closing part 72 of the second hook 80 is away from the lock head seat 61.

[0053] refer to Figure 4 The hook lock seat 31 has a second insertion groove 310 and a second clearance groove 311 formed on the end face facing the lock head seat 61; the third hook 90 is inserted into the second insertion groove 310, and the second clearance groove 311 is directly opposite the swing opening and closing member 72 of the third hook 90 and avoids the first hook 70. To facilitate the passage of the traction rope 200 through the third hook 90, the third hook 90 is inserted obliquely into the second insertion slot 310. The small end 711 of the third hook 90 is located outside the hook lock seat 31. To improve the hooking efficiency of the first hook 70 and the third hook 90, the second clearance slot 311 has an isosceles trapezoidal opening that is narrow at the bottom and wide at the top. The end of the swing opening and closing member 72 of the third hook 90 away from the hinge end is close to the inclined surface of the second clearance slot 311. In this way, when the lock seat 61 shifts and causes the first hook 70 to move, the swing opening and closing member 72 of the first hook 70 will also press against the swing opening and closing member 72 of the third hook 90 under the guiding action of the inclined surface of the second clearance slot 311.

[0054] When working, refer to Figure 9First, the traction rope 200 is connected to the rope head 20: the third hook 90 is inserted into the hook lock seat 31, and the first hook 70 and the second hook 80, which are hooked together, are inserted into the lock head seat 61. Then, the traction rope 200 passes through the third hook 90 and its final end is fixed to the second hook 80, which is hooked to the first hook 70. Then, the traction rope 200 is tied to the target tree branch 300: the lock head seat 61 moves in an arc closer to the hook lock seat 31, so that the swing opening and closing part 72 of the first hook 70 and the swing opening and closing part 72 of the third hook 90 are perpendicular to each other. By applying force and avoiding each other, the first hook 70 and the third hook 90 are hooked together. In this way, the end of the traction rope 200 is hooked by the second hook 80, the first hook 70 and the third hook 90 to form a loop around the target tree branch 300. Then, the lock seat 61 moves back to its original position in an arc. During this process, the first hook 70 and the second hook 80 separate from the lock seat 61 and the third hook 90 separates from the hook lock seat 31. Then, the rope end 20 is removed. Finally, the traction rope 200 is tightened so that the traction rope 200 is tightly tied to the target tree branch 300.

[0055] Example 2: The difference between Example 2 and Example 1 is as follows: (Refer to...) Figure 1 and Figure 10 The tethering seat 30 is equipped with a traction rope 200 mounting base 40; the traction rope 200 mounting base 40 has several locking blocks 41 formed on it; a locking gap is provided between the locking blocks 41 and the tethering seat 30 for the traction rope 200 to be locked in; in this way, after the traction rope 200 passes through the third hook 90, it connects with the second hook 80, and the portion of the traction rope 200 between the third hook 90 and the second hook 80 is locked in the locking gap, thus preventing the traction rope 200 between the third hook 90 and the second hook 80 from accidentally getting caught on branches other than the target branch 300. To facilitate the assembly and disassembly of the traction rope mounting base 40, the traction rope mounting base 40 is connected to the tethering seat 30 by screws.

[0056] Example 3: The difference between Example 3 and Example 1 is as follows: (Refer to...) Figures 5-8 The drive arc rack 63 moves relative to the arc guide portion 62 at a fixed arc angle; an extended arc segment 631 is formed at one end of the drive arc rack 63 near the lock head seat 61; a coaxially arranged vertically penetrating arc guide groove 620 is formed on the arc guide portion 62; the connection portion 6311 between the extended arc segment 631 and the drive arc rack 63 is arc-slidably disposed within the arc guide groove 620; the extended arc segment 631 and the drive arc rack 63 are respectively located on both sides of the arc guide portion 62; an arc guide groove 312 is formed on the hook lock seat 31 for the extended arc segment 631 to be inserted.

[0057] To achieve relative circular arc movement between the drive arc rack 63 and the arc guide 62 at a fixed angle, refer to Figure 6The drive arc rack 63 is close to the arc guide part 62 and has a coaxially arranged limiting guide bar 632. The arc guide part 62 has a limiting guide groove 621 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 drive arc rack 63 is driven by the drive gear 100 to move in an arc at a certain angle, the moving end of the drive arc rack 63 will abut against the corresponding end of the limiting guide groove 621, thereby driving the arc guide part 62 to move in an arc. This completes the extension and retraction of the extended arc segment 631. When the extended arc segment 631 extends, it will extend into the arc guide groove 312 of the hook lock seat 31 before the first hook 70 and the third hook 90 come into contact. This increases the connection strength between the arc guide part 62, the drive arc rack 63 and the hook lock seat 31, thereby preventing the arc guide part 62 from shifting during the arc movement, which would affect the subsequent hooking of the first hook 70 and the third hook 90.

[0058] In other embodiments, the limiting guide groove 621 may be formed on the driving arc rack 63, and the limiting guide bar 632 may be set on the arc guide portion 62.

[0059] To further increase the movement stability of the arc guide part 62, an arc-shaped auxiliary guide bar 622 is formed on the end face of the arc guide part 62 away from the driving arc rack 63, which is coaxially arranged; an auxiliary guide groove that cooperates with the auxiliary guide bar 622 is formed on the telescopic arc groove 300; the auxiliary guide bar 622 plays the role of arc guiding and also acts as a reinforcing rib, so that the arc guide part 62 is not used for offset.

[0060] Example 4: The difference between Example 4 and Example 1 is as follows: (Refer to...) Figure 1 A monitoring device is installed on the rope anchor 30; the monitoring device includes a monitoring camera 50; the power supply on the rope anchor 30 supplies power to the monitoring camera 50; the monitoring camera 50 is connected to the rope anchor 30 through a universal tube 51. Because the universal tube 51 is both flexible and strong, it allows the monitoring camera 50 to face any position. The monitoring camera 50 is directly facing the hook positions of the first hook 70 and the third hook 90, so 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 a mobile APP.

[0061] Example 5: The difference between Example 5 and Example 1 is as follows: (Refer to...) Figure 5The bottom of the tethering seat 30 is formed with a connecting rod 32, and a connecting vertical plane is formed on the connecting rod 32. The top of the insulating rod 10 is also formed with a connecting vertical plane. 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 abut against each other and their connecting through holes face each other. Then, a bolt passes through a pair of connecting through holes to connect the insulating rod 10 and the connecting rod 32. To prevent them from rotating relative to each other, several fan-shaped connecting limit blocks 321 are formed on the connecting vertical planes of the connecting rod 32 and the insulating rod 10, evenly distributed along the circumference of the connecting through holes. 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 tethering seat 30 and the insulating rod 10 are easy to assemble and disassemble, and easy to store and transport. For even more convenient storage and transportation, 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 scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
