Description

Technical Field

[0001] The invention relates to the technical field of power transmission line repair, and in particular to a ground wire repair device for a power transmission line. Background Art

[0002] Overhead ground wire, also known as lightning arrester, refers to the wire directly connected to the earth on high-voltage and ultra-high-voltage lines. Due to the shielding of the wire by the overhead ground wire and the coupling between the wire and the overhead ground wire, the chance of lightning directly striking the wire can be reduced. When lightning strikes the tower, part of the lightning current can be diverted through the overhead ground wire, thereby reducing the potential on the top of the tower and improving the lightning resistance level.

[0003] During the use of overhead ground wires, metal wires may be damaged and broken in some locations. After the metal wires are broken, they will droop downwards, causing the ground wires to be unable to be used normally. In the prior art, most repairs are done by manual climbing, and the metal wires are manually rewound. However, when the broken wires droop down a long distance, manual re-winding cannot be achieved in a short time, and manual repair is inefficient and dangerous at high altitudes.

[0004] The patent with publication number CN118213906A discloses an aerial operation robot for repairing broken strands of power transmission lines. The flying platform can carry the operation mechanism from the ground to the broken strands at high altitudes for repair work. The robot is equipped with a pan-tilt camera and can accurately locate the broken strands of the power transmission line. The multi-degree-of-freedom robot arm consists of 5 joints and can realize three-dimensional space movement with high flexibility. At the same time, by cooperating with the wire-straightening mechanical claw and the repairing mechanical claw, the wire-straightening mechanical claw can first straighten the broken strand of the power transmission line, and then the repairing mechanical claw can buckle the repair part at the broken strand to complete the broken strand repair work. The repair efficiency is high; the negative pressure adsorption component can be used to fix the repair part on the inner wall of the fixing sleeve to avoid it falling off during flight, and when the repair part is buckled, the transmission release component can be used to synchronously release the adsorption and fixing effect on the repair part, solving the problem that the repair part is difficult to fix and automatically falls off before and after the repair operation; however, during use, the broken power transmission line is straightened by cooperating with the wire-straightening mechanical claw and the repair mechanical claw. During the straightening process, it is impossible to fit the ground wire to achieve spiral rotation, and the spiral direction of the metal wire cannot be effectively reset, which has limitations in use.

DETAILED DESCRIPTION

[0032] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Example 1

[0034] Combination Figure 1-4 As shown, the transmission line ground wire repair device includes a rotating drive assembly. In the actual ground wire repair process, it is necessary to use an external overhead cable walking device. The transmission line ground wire repair device needs to be installed on the external overhead cable walking device to walk on the ground wire of the transmission line and repair the damaged position;

[0035] A first connecting frame 6 is installed on the rotating end of the rotary drive assembly, and a compression repair assembly is installed on the end of the first connecting frame 6 away from the rotary drive assembly. The compression repair assembly includes a first telescopic drive member 7 and a compression seat 8. Two first telescopic drive members 7 are provided, and the two first telescopic drive members 7 are symmetrically installed on the two first connecting frames 6. Two compression seats 8 are provided, and the two compression seats 8 are symmetrically installed on the telescopic ends of the two first telescopic drive members 7. The two first telescopic drive members 7 drive the two compression seats 8 to be combined to surround the ground wire;

[0036] The clamping seat 8 is provided with an arc-shaped groove, and the ground wire can be accommodated in the arc-shaped grooves of the two clamping seats 8 for surrounding clamping repair.

[0037] The rotary drive assembly includes a first mounting frame 1, two drive motors 2 are symmetrically mounted on the lower part of the first mounting frame 1, the output ends of the two drive motors 2 are respectively fixedly connected to two gears 3, a bearing ring 4 is mounted on the first mounting frame 1, a gear ring 5 is rotatably mounted on the outer ring of the bearing ring 4, and two first connecting frames 6 are symmetrically fixedly connected to the gear ring 5 on one side away from the first mounting frame 1.

[0038] A circular hole is opened on the first mounting frame 1, a notch is opened on the upper part of the circular hole of the first mounting frame 1, and notches are opened on the upper parts of the bearing ring 4 and the gear ring 5. When the transmission line ground wire repair device is installed on the ground wire, the ground wire enters into the notches of the first mounting frame 1, the bearing ring 4 and the gear ring 5, and then the ground wire can be located between the two clamping seats 8.

[0039] In this embodiment, in actual use, the power transmission line ground wire repair device moves on the ground wire of the power transmission line with the help of an external overhead cable walking device, moves to the starting position of the damaged ground wire, and then the two first telescopic driving members 7 drive the two clamping seats 8 to merge and clamp the ground wire;

[0040] Furthermore, in order to spirally wind the damaged and scattered metal wires again, the external overhead cable walking device will drive the power transmission line ground wire repair device to walk on the ground wire. During the walking process, the driving motor 2 drives the gear 3 to rotate, and the gear 3 drives the gear ring 5 to rotate. The gear ring 5 drives the first connecting frame 6, the first telescopic drive member 7 and the clamping seat 8 to rotate. The two clamping seats 8 rotate in the spiral winding direction of the metal wire while keeping the ground wire clamped together, and walk along the ground wire during the rotation, and then the scattered metal wires are rotated and fitted to the surface of the ground wire in a spiral winding manner, completing the rewinding and repair of the damaged and scattered ground wires, so that the scattered metal wires can be rewound to the damaged vacant position, thereby realizing the repair of the damaged position.

[0041] Until the pressing seat 8 moves to the end of the scattered wire, the entire scattered wire is completely reset and repaired.

[0042] After the resetting is completed, the metal wire at the damaged position can be fixed by wrapping it with tape to prevent the metal wire from spreading again after the pressing seat 8 is removed.

[0043] It also includes a limit assembly, which includes a third connecting frame 26 and a limit adjustment ring 27. Two third connecting frames 26 are symmetrically fixed to the two outer shells of the two first telescopic driving members 7. The two third connecting frames 26 are fixed to the limit adjustment ring 27 at one end away from the first telescopic driving member 7. The upper part of the limit adjustment ring 27 is provided with a notch.

[0044] During the repair process, due to the gravity of the metal wire itself, the metal wire will hang down for a distance. At this time, since the metal wire hangs down too much, it is difficult to reset the metal wire with a large downward hanging amplitude by the clamping force by directly rotating and tightening the clamping seat 8. Therefore, when in use, the hanging metal wire will first enter the limit adjustment ring 27 from the notch, thereby completing the hanging metal wire being supported on the inner side of the limit adjustment ring 27, which is convenient for the clamping seat 8 to further reset and wind, thereby improving the repair efficiency.

[0045] Example 2

[0046] Combination Figure 1-13 As shown, the difference between this embodiment and embodiment 1 is that:

[0047] The metal wire is normally in a taut state. When it is broken, it will shrink in a short distance due to its own stress. Therefore, when the metal wire is rewound, there will be a small gap at its end.

[0048] Further optimization includes a tensioning docking assembly, two of which are provided, one tensioning docking assembly is installed on each clamping seat 8, the tensioning docking assembly includes a fourth telescopic drive member 28, a sliding platform 29, a fifth telescopic drive member 30, a connecting plate 31 and a positioning cone 32, an inner recessed groove is provided on the arc-shaped groove surface of the clamping seat 8, the sliding platform 29 slides in the inner recessed groove, the fourth telescopic drive member 28 is installed on one side of the inner recessed groove, the telescopic end of the fourth telescopic drive member 28 is connected to the sliding platform 29, the fifth telescopic drive member 30 is installed on the sliding platform 29, the connecting plate 31 is fixedly connected to the telescopic end of the fifth telescopic drive member 30, and a plurality of positioning cones 32 are fixedly connected to the connecting plate 31.

[0049] The positioning cone 32 has a sharp tip in order to be able to bite the wire at the end thereof and stretch it.

[0050] In this embodiment, during the rotation and advancement of the pressing seat 8, the positioning cone 32 is completely hidden in the sunken groove of the pressing seat 8, and the tip of the positioning cone 32 does not protrude from the sunken groove. At this time, the pressing seat 8 normally fits the metal wire spirally and advances. When the pressing seat 8 moves to the end of the scattered metal wire, the metal wire is about to be reset. At this time, the fifth telescopic driving member 30 extends to drive the positioning cone 32 to extend, protrude from the sunken groove of the pressing seat 8, and penetrate into the surface of the metal wire, forming a small pit on the surface of the metal wire. Then, after the tip of the positioning cone 32 is inserted into the small pit, it will form an effective contact friction force on the metal wire. The fourth telescopic driving member 28 rotates slightly, and then the positioning cone 32 will form a strong pull on the metal wire, so that the metal wire is pulled in a short distance and restored to a stretched state, and then the gap at the broken position can be eliminated and it fits tightly again.

[0051] During use, the fourth telescopic driving member 28 can be extended to drive the sliding table 29 to translate, and then the sliding table 29 drives the positioning cone 32 to translate, and adjusts the position of the positioning cone 32 on the clamping seat 8 to adapt to the metal wires with different contact positions of the clamping seat 8.

[0052] Example 3

[0053] Combination Figure 1-13 As shown, the difference between this embodiment and embodiment 2 is that:

[0054] In the actual ground wire repair process, after the original damaged metal wire is restored, in order to further protect the repair position, it is necessary to wrap a pre-twisted wire around the outside of the broken position to enhance the strength of the ground wire.

[0055] Further optimization also includes a temporary clamping assembly, which includes a second telescopic drive member 9, a first arc clamp 10, a third telescopic drive member 11 and a second arc clamp 14. The second telescopic drive member 9 is installed on the first mounting frame 1, the first arc clamp 10 is fixedly connected to the telescopic end of the second telescopic drive member 9, the third telescopic drive member 11 is fixedly connected to the first mounting frame 1, the second arc clamp 14 is fixedly connected to the telescopic end of the third telescopic drive member 11, and the first arc clamp 10 is opposite to the second arc clamp 14.

[0056] The pre-twisted wire can be placed on the upper side of the ground wire by a mechanical arm or manually, and then wound. In the initial stage of winding, since the pre-twisted wire is in an independent state, it is impossible to wind it directly using the clamping seat 8. The two ends of the pre-twisted wire lack support and will fall directly. Therefore, after the pre-twisted wire is placed on the ground wire, the starting position of the pre-twisted wire is attached to the ground wire. The starting position of the pre-twisted wire is between the first arc clamp 10 and the second arc clamp 14. Then the second telescopic driving member 9 is extended to drive the first arc clamp 10 to move, and the third telescopic driving member 11 is extended to drive the second arc clamp 14 to move. , the starting end of the pre-twisted wire on the ground wire can be clamped, and then the starting end is fixed, which is convenient for the pressing seat 8 to carry out subsequent winding. During the winding process, the two pressing seats 8 continue to be close to and fit the outside of the ground wire, and the pre-twisted wire is placed on the upper side of the pressing seat 8. Therefore, during the rotation of the pressing seat 8, the upper side of the pressing seat 8 will continuously rotate the pre-twisted wire, thereby, the pre-twisted wire is wound around the ground wire in circles. Due to the spiral characteristics of the pre-twisted wire itself, through the stress of its spiral, the pre-twisted wire will be firmly wound around the ground wire, forming an effective protection for the outside of the damaged position.

[0057] Whether the pre-twisted wire is placed on the upper side of the ground wire by a mechanical arm or manually, there will be corresponding errors and misalignments, that is, the starting part of the pre-twisted wire cannot be wound at the starting end while being clamped, and during the subsequent rotation and winding process of the clamping seat 8, the starting position will be misaligned, resulting in the entire pre-twisted wire winding being misaligned and not firm;

[0058] Therefore, in this embodiment, it also includes a toggle sorting component, which includes a first elastic telescopic rod 13, a first fixed seat 15, an annular slide rail 16, a sliding seat 17, a first shaft rod 18, a toggle rod 19, a second shaft rod 20, a second elastic telescopic rod 21, a third shaft rod 22, a linkage rod 23, a fourth shaft rod 24 and a second fixed seat 25. The telescopic end of the third telescopic driving member 11 is connected to the first elastic telescopic rod 13, the telescopic end of the first elastic telescopic rod 13 is connected to the second arc clamp 14, the first fixed seat 15 is fixed to the telescopic part of the first elastic telescopic rod 13, the annular slide rail 16 is fixed to the first fixed seat 15 through a bracket, a notch is provided at the lower part of the annular slide rail 16, and the sliding seat 17 is slidably installed on the annular slide rail 16, the first shaft rod 18 is fixed to the sliding seat 17, the toggle rod 19 is fixed to the first shaft rod 18, the first shaft rod 18 and the toggle rod 19 are vertically arranged, the second shaft rod 20 is fixed to the first fixed seat 15 through a bracket, the fixed end of the second elastic telescopic rod 21 is hinged to the second shaft rod 20, the telescopic end of the second elastic telescopic rod 21 is hinged to the first shaft rod 18, the third shaft rod 22 is installed on the fixed part of the second elastic telescopic rod 21 on one side close to the telescopic end, the second fixed seat 25 is fixed to the fixed part of the first elastic telescopic rod 13 on one side close to the telescopic end, the fourth shaft rod 24 is fixed to the second fixed seat 25, the first end of the linkage rod 23 is hinged to the fourth shaft rod 24, and the second end of the linkage rod 23 is hinged to the third shaft rod 22.

[0059] It also includes a second connecting frame 12 , and two third telescopic driving members 11 are provided. The telescopic ends of the two third telescopic driving members 11 are fixedly connected to the second connecting frame 12 , and the second connecting frame 12 is fixedly connected to the fixed end of the first elastic telescopic rod 13 .

[0060] In order to be able to clamp the pre-twisted wire at the starting position and ensure that it is not misaligned, while the first arc clamp 10 and the second arc clamp 14 are close to each other to clamp the starting end of the pre-twisted wire, the starting end of the pre-twisted wire is first placed on the upper side of the ground wire, and then the third telescopic drive member 11 is extended to drive the second connecting frame 12, the first elastic telescopic rod 13 and the second arc clamp 14 to move in the direction close to the ground wire, and then the second arc clamp 14 presses the pre-twisted wire on the upper side of the ground wire. Due to the elastic force of the first elastic telescopic rod 13 itself, the second arc clamp 14 will not completely press the pre-twisted wire at this time, but only limit its downward pressure through the elastic force. At this time, the bottom end of the toggle rod 19 is against the upper side of the ground wire, and the pre-twisted wire is located on one side of the toggle rod 19;

[0061] Then the second connecting frame 12 continues to descend, so that the first elastic telescopic rod 13 continues to be compressed, and then the fixing part on the upper side of the first elastic telescopic rod 13 continues to move downward, driving the second fixing seat 25 to move downward, so that the second fixing seat 25 drives the fourth shaft rod 24 to move downward, and the fourth shaft rod 24 presses the second elastic telescopic rod 21 downward through the linkage rod 23 and the third shaft rod 22, so that the second elastic telescopic rod 21 starts to rotate downward, and the telescopic end of the second elastic telescopic rod 21 drives the first shaft rod 18 to move downward, and the first shaft rod 18 drives the sliding seat 17 to move downward, and the sliding seat 17 slides downward in the annular slide rail 16, thereby driving the toggle rod 19 to start moving along the track of the annular slide rail 16, and the bottom end of the toggle rod 19 abuts against the surface of the ground wire and starts to slide downward;

[0062] Then the toggle rod 19 will start to toggle the pre-twisted wire on one side downward, that is, the toggle rod 19 toggle the pre-twisted wire to start winding and rotating downward in its spiral direction, thereby, the starting position of the pre-twisted wire can be wound in the correct position under the toggle of the toggle rod 19, and the position pressed by the lower side of the second arc clamp 14 can also be gradually adjusted to the correct position as the pre-twisted wire is toggled and wound. Thus, the starting end of the pre-twisted wire can be spirally wound while being compressed, and the correct position of its body is achieved while winding. After the starting end of the pre-twisted wire is wound, the second telescopic drive member 9 is extended to drive the first arc clamp 10 to compress the pre-twisted wire and wind it to the position on the lower side, and the compression amount of the first elastic telescopic rod 13 also reaches the limit, and then the second arc clamp 14 compresses the pre-twisted wire on the upper side, thereby realizing the compression and fixation of the winding position of the starting end of the pre-twisted wire, and ensuring that a part of the starting position will be pre-wound, correcting its position, avoiding dislocation during the winding process, and avoiding the pre-twisted wire from being unable to fully fit the ground wire, thereby achieving a better pre-twisted wire winding effect.

[0063] One end of the toggle rod 19 away from the first shaft rod 18 is a spherical head, and the spherical head contacts and slides on the surface of the ground wire without causing damage to the surface of the ground wire.

[0064] In the specific implementation, in order to facilitate the ground wire to move from top to bottom into between the first arc clamp 10 and the second arc clamp 14, the second arc clamp 14 and the first arc clamp 10 are not arranged directly above and below, but may be arranged with a certain angle of deviation.
