Description

Technical Field

[0001] This invention relates to the field of power transmission line maintenance technology, specifically to a gripper mechanism and a device for repairing broken strands in power transmission lines. Background Technology

[0002] The statements herein provide only background information in relation to this invention and do not necessarily constitute prior art.

[0003] Traditional transmission line strand breakage repair equipment requires a clamping mechanism to compress the repair patch, causing it to wrap around the broken strand. For example, there is currently an overhead ground wire electric repair mechanism that uses a push rod motor to drive the repair clamp assembly to close, clamping the repair clamp onto the ground wire for repair. This repair clamp assembly includes a planar four-bar linkage and the repair clamp assembly itself. The lifting and lowering movement of the push rod connector head can drive the repair clamp assembly through the planar four-bar linkage, opening and closing the repair clamp assembly. However, the above-mentioned repair clamp assembly can only accommodate one wire diameter. To repair lines with other wire diameters, the entire repair clamp assembly and the repair patch need to be replaced. Therefore, the application range of the above-mentioned repair clamp assembly is limited. The repair clamp assembly does not provide sufficient bending pressure on the repair patch, only covering most of the line. This directly reduces the repair pressure of the repair patch, making it unsuitable for strand breakage repair in certain extreme situations (such as when the broken wire is located in the part not covered by the repair patch). Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a gripper mechanism and a power transmission line strand breakage repair device, which overcomes the defects of the gripper mechanism in the current strand breakage repair device.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: In a first aspect, embodiments of the present invention provide a gripper mechanism, including a movable block connected to a telescopic component. One side of the movable block is hinged to one end of a central connecting rod. The other end of the central connecting rod is hinged to one end of a first central pressure rod via a first connecting shaft. The other end of the first central pressure rod is hinged to one end of a second central pressure rod. The other end of the second central pressure rod is hinged to a housing. Both ends of the other side of the movable block are hinged to one end of a side connecting rod. The other end of the side connecting rod is hinged to one end of a first side pressure rod via a second connecting shaft. The other end of the first side pressure rod is hinged to one end of a second side pressure rod. The other end of the second side pressure rod is hinged to the housing. The first connecting shaft is slidably connected to the housing via a first guide groove provided in the housing. The second connecting shaft is slidably connected to the housing via a second guide groove provided in the housing.

[0006] Optionally, the middle position on one side of the moving block is hinged to one end of the central connecting rod via a third connecting shaft, and the two ends on the other side are hinged to one end of the side connecting rod via a fourth connecting shaft.

[0007] Optionally, the third connecting shaft is slidably connected to the housing through a first vertical groove in the housing, and the fourth connecting shaft is slidably connected to the housing through a second vertical groove in the housing.

[0008] Optionally, both the end of the first intermediate pressure rod used to connect to the second intermediate pressure rod and the end of the first side pressure rod used to connect to the second side pressure rod are provided with a pressing component, and the pressing component is provided with a right-angle groove that matches the end of the repair patch.

[0009] Optionally, the housing has a stop on the feeding side, the stop and the stop mounting seat are elastically connected by an elastic element, the stop mounting seat is fixedly connected to the housing, and the part of the top of the stop for contacting the repair piece is provided with an inclined surface so that the stop can overcome the elastic force of the elastic element and move downward under the action of the feeding repair piece to realize the feeding of the repair piece.

[0010] Secondly, embodiments of the present invention provide a transmission line strand break repair device, including a frame, a traveling mechanism for cooperating with a transmission line at the top of the frame, a gripper mechanism as described in the first aspect installed below the traveling mechanism, a pusher mechanism on one side of the gripper mechanism and a line straightening mechanism on the other side, the gripper mechanism being connected to a first lifting mechanism installed on the frame, and the line straightening mechanism being connected to a second lifting mechanism installed on the frame.

[0011] Optionally, the pusher mechanism includes a storage compartment, one side wall of which has a feeding port and the top of the other side wall has a discharging port. Inside the storage compartment, there is a pressing block. The top surface of the pressing block matches the shape of the repair patch. The pressing block is slidably connected to a sliding shaft inside the storage compartment. An elastic element is provided between the pressing block and the bottom surface of the storage compartment. The top of the storage compartment has a pusher drive that is opposite to the discharging port. The pusher drive is connected to the pusher block and can push the repair patch out through the pusher block. Furthermore, the pressure block is connected to the handle, which extends to the outside of the storage compartment through a vertical groove provided on the wall of the storage compartment.

[0012] Optionally, the push block includes a push block body that matches the shape of the repair patch, the push block body having a protrusion that matches the shape of the repair patch, and a stepped surface formed between the protrusion and the push block body for engaging with the repair patch. Furthermore, the outer edge of the stepped surface is chamfered.

[0013] Optionally, the frame includes a back plate, the top of which is provided with a walking mechanism mounting frame, on which a walking mechanism is mounted, and the top of the walking mechanism mounting frame is connected to a hanging ring for cooperating with flight equipment. The push plate mechanism, the first lifting mechanism, and the second lifting mechanism are all installed at the bottom of the back plate. The walking mechanism mounting frame is fixed with a first guide bar, and the back plate is fixed with a second guide bar. A guide channel is formed between the first guide bar and the second guide bar, and the top of the guide channel extends to the bottom of the walking mechanism. Furthermore, the guide channel includes a first guide section, one end of which is connected to a second guide section extending below the walking mechanism, and the other end of which is connected to a third guide section with a gradually expanding structure.

[0014] Optionally, the cable straightening mechanism includes a cable straightening plate, which is connected to the second lifting mechanism, and the top of the cable straightening plate is provided with a cable straightening groove.

[0015] The beneficial effects of this invention are as follows: 1. The gripper mechanism of the present invention has a first connecting shaft slidably connected to the housing through a first guide groove provided in the housing, and a second connecting shaft slidably connected to the housing through a second guide groove provided in the housing. It is also equipped with a second intermediate pressure rod and a second side pressure rod. Since the ends of the first intermediate pressure rod and the first side pressure rod used to connect the intermediate connecting rod and the side connecting rod can slide along the first guide groove and the second guide groove respectively, the first intermediate pressure rod and the first side pressure rod can achieve a large downward pressure, allowing the repair patch to be completely bent and wrap around the entire wire diameter, greatly improving the repair pressure of the repair patch. Broken strands of steel wire at any position can be wrapped. Simultaneously, the gripper mechanism can adapt to various wire diameters, and the same repair patch can be used to repair transmission lines of various wire diameters without changing the gripper mechanism and the repair patch. The entire gripper mechanism has strong applicability.

[0016] 2. In the transmission line strand breakage repair device of the present invention, the outer edge of the step surface of the push block is provided with a chamfer structure. With the setting of the chamfer structure, when the step surface pushes the current repair piece, if it also contacts the repair piece below, the chamfer structure will generate a force on the repair piece below to move it away from the step surface. This allows the protruding part of the push block to replace the gap caused by the current repair piece being pushed out, ensuring that the repair piece is pushed out more smoothly and is not stuck.

[0019] Example 1 This embodiment provides a gripper mechanism, such as Figure 1-4 As shown, the gripper mechanism 1 includes a housing, a moving block 1-1, a telescopic component 1-2, a central connecting rod 1-3, a first central pressure rod 1-4, a second central pressure rod 1-5, two side connecting rods 1-6, two first side pressure rods 1-7, and two second side pressure rods 1-8. The moving block 1-1, the telescopic component 1-2, the central connecting rod 1-3, the first central pressure rod 1-4, the second central pressure rod 1-5, the side connecting rods 1-6, the first side pressure rods 1-7, and the second side pressure rods 1-8 are located in the corresponding cavities of the housing.

[0020] The movable block 1-1 is connected to the telescopic component 1-2. The telescopic component 1-2 can drive the movable block 1-1 to make vertical movements. In this embodiment, the telescopic component 1-2 is an electric push rod or a cylinder. Since the gripper mechanism is for high-altitude operation, the telescopic component is preferably an electric push rod. The telescopic part of the electric push rod is connected to the movable block 1-1 and can drive the movable block 1-1 to make vertical movements.

[0021] In this embodiment, the housing can be an integral structure or a split structure. In this embodiment, the housing adopts a split structure. The housing is composed of a first guide positioning plate 1-9, a second guide positioning plate 1-10, a third guide positioning plate 1-11, and a fourth guide positioning plate 1-12, which are detachably connected by bolts. The second guide positioning plate 1-10 and the third guide positioning plate 1-11 are located between the first guide positioning plate 1-9 and the fourth guide positioning plate 1-12.

[0022] Among them, the central connecting rod 1-3, the first central pressure rod 1-4, and the second central pressure rod 1-5 are located in the cavity formed between the second guide positioning plate 1-10 and the third guide positioning plate 1-11. The side connecting rod 1-6, the first side pressure rod 1-7, and the second side pressure rod 1-8 on one side are located in the cavity formed by the first guide positioning plate 1-9 and the second guide positioning plate 1-10. The side connecting rod 1-6, the first side pressure rod 1-7, and the second side pressure rod 1-8 on the other side are located in the cavity formed by the third guide positioning plate 1-11 and the fourth guide positioning plate 1-12.

[0023] The middle of one side of the movable block 1-1 is hinged to one end of the middle connecting rod 1-3 via the third connecting shaft 1-13. The other end of the middle connecting rod 1-3 is hinged to one end of the first middle pressure rod 1-4 via the first connecting shaft 1-14. The other end of the first middle pressure rod 1-4 is connected to one end of the second middle pressure rod 1-5 via the first middle pressure rod connecting shaft 1-15. The other end of the second middle pressure rod 1-5 is fixed with the second middle pressure rod connecting shaft 1-16. The second middle pressure rod connecting shaft 1-16 is rotatably connected to the second guide positioning plate 1-10 and the third guide positioning plate 1-11, so that the second middle pressure rod 1-5 is hinged to the second guide positioning plate 1-10 and the third guide positioning plate 1-11 via the second middle pressure rod connecting shaft 1-16.

[0024] The two ends of the other side of the movable block 1-1 are hinged to one end of the corresponding side connecting rod 1-6 via the fourth connecting shaft 1-17. The other end of the side connecting rod 1-6 is hinged to one end of the first side pressure rod 1-7 via the second connecting shaft 1-18. The other end of the first side pressure rod 1-7 is hinged to one end of the second side pressure rod 1-8 via the first side pressure rod connecting shaft 1-19. The other end of the second side pressure rod 1-8 is fixed to the second side pressure rod connecting shaft 1-20. The second side pressure rod 1-8 on one side is hinged to the first guide positioning plate 1-9 and the second guide positioning plate 1-10 via the second side pressure rod connecting shaft 1-20. The second side pressure rod 1-8 on the other side is hinged to the third guide positioning plate 1-11 and the fourth guide positioning plate 1-12 via the second side pressure rod connecting shaft 1-20. Specifically, the second side pressure rod connecting shaft 1-20 is rotatably connected to the corresponding guide positioning plate to realize the hinge connection between the second side pressure rod 1-8 and the corresponding guide positioning plate.

[0025] In this embodiment, as Figures 5-6As shown, the first connecting shaft 1-14 passes through the first guide groove 1-21 opened in the first guide positioning plate 1-9, the second guide positioning plate 1-10, the third guide positioning plate 1-11, and the fourth guide positioning plate 1-12, and is slidably connected to the first guide positioning plate 1-9, the second guide positioning plate 1-10, the third guide positioning plate 1-11, and the fourth guide positioning plate 1-12 through the first guide groove 1-21. The second connecting shaft 1-18 passes through the second guide groove 1-22 opened in the first guide positioning plate 1-9, the second guide positioning plate 1-10, the third guide positioning plate 1-11, and the fourth guide positioning plate 1-12, and is slidably connected to the first guide positioning plate 1-9, the second guide positioning plate 1-10, the third guide positioning plate 1-11, and the fourth guide positioning plate 1-12 through the second guide groove 1-22.

[0026] In this embodiment, the first guide groove 1-21 and the second guide groove 1-22 are both wavy line grooves, which are fitted according to the motion trajectory of the first connecting shaft 1-14 and the second connecting shaft 1-18. Their specific parameters are not described in detail here.

[0027] Furthermore, in order to guide the lifting and lowering movement of the moving block 1-1, the third connecting shaft 1-13 passes through the first vertical groove 1-23 opened in the first guide positioning plate 1-9, the second guide positioning plate 1-10, the third guide positioning plate 1-11, and the fourth guide positioning plate 1-12, and is slidably connected to the first guide positioning plate 1-9, the second guide positioning plate 1-10, the third guide positioning plate 1-11, and the fourth guide positioning plate 1-12 through the first vertical groove 1-23. The fourth connecting shaft 1-17 passes through the second vertical groove 1-24 opened in the first guide positioning plate 1-9, the second guide positioning plate 1-10, the third guide positioning plate 1-11, and the fourth guide positioning plate 1-12, and is slidably connected to the first guide positioning plate 1-9, the second guide positioning plate 1-10, the third guide positioning plate 1-11, and the fourth guide positioning plate 1-12 through the second vertical groove 1-24.

[0028] A push rod pad 1-25 is provided between the bottom ends of the first guide positioning plate 1-9 and the fourth guide positioning plate 1-12. The bottom end of the electric push rod is fixedly connected to the push rod pad 1-25. A fixing block 1-26 is provided at the bottom of the second guide positioning plate 1-10 and the third guide positioning plate 1-11. The fixing block 1-26 contacts the electric push rod to prevent the electric push rod from shaking.

[0029] In this embodiment, the first side pressure rod 1-7, the second side pressure rod 1-8, the first intermediate pressure rod 1-4, and the second intermediate pressure rod 1-5 are all arc-shaped rods, which can wrap the repair patch around the power transmission line.

[0030] The outer side of the end of the first intermediate pressure rod 1-4, which is used to connect to the second intermediate pressure rod, is provided with a pressing component 1-27. The pressing component has a right-angle groove for engaging with one side end of the repair piece. The outer side of the end of the first side pressure rod 1-7, which is used to connect to the second side pressure rod, is also provided with a pressing component 1-27. The pressing component 1-27 has a right-angle groove for engaging with the other side end of the repair piece. The right-angle groove prevents the repair piece from detaching from the gripper mechanism during bending, ensuring the smooth bending process of the repair piece.

[0031] Furthermore, such as Figure 7 As shown, the feed side of the housing is also provided with a stop block 1-28. The stop block 1-28 is elastically connected to the stop block mounting seat 1-29 through a first elastic element. The stop block mounting seat 1-29 is fixed to the housing by bolts. Specifically, the first elastic element is a first spring 1-30. One end of the first spring 1-30 is connected to the stop block 1-28, and the other end is connected to the stop block mounting seat 1-29.

[0032] The top of the stop block 1-28 has a beveled side for contacting the repair piece 14. When the repair piece 14 moves toward the gripper mechanism, it contacts the beveled side of the stop block 1-28. Under the action of the repair piece 14, the stop block 1-28 can overcome the elastic force of the first spring 1-30 and move downward, so that the repair piece 14 can move into the space between the first intermediate pressure rod 1-4, the second intermediate pressure rod 1-5, the first side pressure rod 1-7, and the second side pressure rod 1-8 of the gripper mechanism. When the repair piece 14 disengages from the stop block 1-28, the stop block 1-28 can reset under the action of the first spring 1-30. Thus, the stop block 1-28 limits the repair piece 14 in the gripper mechanism and prevents the repair piece 14 from disengaging from the gripper mechanism.

[0033] The working principle of the gripper mechanism in this embodiment is as follows: like Figure 8 As shown, the repair piece 14 moves toward the gripper mechanism. The repair piece 14 first contacts the inclined surface at the top of the stop block 1-28. By cooperating with the inclined surface, the stop block 1-28 overcomes the elastic force of the first spring 1-30 and moves downward. The repair piece 14 enters the gripper mechanism. After the repair piece separates from the stop block, the stop block resets and limits the repair piece.

[0034] At this time, the electric push rod drives the moving block 1-1 to rise. The moving block 1-1 drives the first medium pressure rod 1-4 and the first side pressure rod 1-7 to move in opposite directions through the middle connecting rod 1-3 and the side connecting rod 1-6, so as to wrap the repair piece 14 around the broken strand of the transmission line.

[0035] Because the ends of the first intermediate pressure rod 1-4 and the first side pressure rod 1-7, which connect the intermediate connecting rod 1-3 and the side connecting rod 1-6, can slide along the first guide groove 1-21 and the second guide groove 1-22 respectively, the first intermediate pressure rod 1-4 and the first side pressure rod 1-7 can achieve a large downward pressure, allowing the repair piece 14 to be completely bent and wrap around the entire wire diameter, greatly improving the repair pressure of the repair piece. Broken strands of wire at any location can be wrapped. Meanwhile, as... Figure 9 As shown, the gripper mechanism can adapt to various wire diameters. Using the same repair piece 14, it can repair transmission lines of various wire diameters without replacing the gripper mechanism and the repair piece 14. The entire gripper mechanism has strong applicability.

[0036] Example 2 This embodiment provides a device for repairing broken strands in power transmission lines, such as... Figures 10-11 As shown, the device includes a frame, a walking mechanism 2 on the top of the frame, a gripper mechanism 1 as described in Embodiment 1 below the walking mechanism 2, a pusher mechanism 3 on one side of the feed end of the gripper mechanism 1, and a straightening mechanism 4 on the other side.

[0037] The pusher mechanism 3 is used to push the repair piece 14 into the gripper mechanism 1. The gripper mechanism 1 is connected to the first lifting mechanism installed on the frame, and the straightening mechanism 4 is connected to the second lifting mechanism installed on the frame.

[0038] The traveling mechanism 2 is used to cooperate with the power transmission line. The traveling mechanism 2 can drive the entire repair device to travel along the power transmission line, so that the repair device can reach the broken strand of the power transmission line.

[0039] like Figures 12-13 As shown, the frame includes a back plate 6, a hanging ring 7, a walking mechanism mounting frame 8, and a guide assembly.

[0040] The top of the back plate 6 is provided with a walking mechanism mounting bracket 8. In this embodiment, two walking mechanism mounting brackets 8 are provided. The walking mechanism mounting brackets 8 are fixed to the top of the back plate 6 by bolts. In this embodiment, as shown... Figure 13 As shown, the walking mechanism mounting frame 8 adopts an inverted U-shaped plate, and its inner side is fixedly connected to the back plate 6 by bolts, as shown. Figure 14As shown, the walking mechanism mounting frame 8 has a walking wheel 2-1 inside. The walking wheel 2-1 is fixedly connected to the wheel axle 2-3. The wheel axle is rotatably connected to the walking mechanism mounting frame 8. The outer side of the walking mechanism mounting frame 8 is fixed with a support 2-4 by bolts. The support 2-4 is fixedly connected to the walking drive element 2-2. In this embodiment, the walking drive element 2-2 adopts a walking motor and a reducer. The walking motor is fixed to the reducer. The output shaft of the walking motor is connected to the reducer. The output shaft of the reducer is connected to the wheel axle 2-3. It can be understood that the walking drive element 2-2 can also adopt other electrically driven devices that can output rotational motion. Those skilled in the art can choose according to actual needs. It will not be described in detail here. The walking wheel 2-1, wheel axle 2-3, support 2-4 and walking drive element 2-2 together constitute the walking mechanism 2.

[0041] The output shaft of the walking motor rotates, which drives the walking wheel 2-1 to rotate, thus enabling the entire repair device to move along the power transmission line.

[0042] The top of the two aforementioned walking mechanism mounting frames is fixed with a hanging ring 7. The hanging ring 7 adopts an inverted U-shaped structure, with one end fixedly connected to one of the walking mechanism mounting frames 8 and the other end fixedly connected to the other walking mechanism mounting frame 8. The hanging ring 7 is used to cooperate with the hook at the end of the boom 10 of the flying equipment, such as the drone 9, so that the entire power transmission line repair device can be used to cooperate with the power transmission line by the flying equipment, without the need for manual climbing or building of tracks, avoiding the risk of falling from a height and greatly reducing the safety hazards of operation.

[0043] Furthermore, to facilitate the carrying of the entire repair device, the hanging ring 7 is detachably and fixedly connected to the walking mechanism mounting frame using fasteners. The two ends of the hanging ring 7 are provided with circular fixing holes. The fasteners can be existing bolts or spring pins; preferably, spring pins 10 are used. Existing components can be used for the spring pins 10, and they will not be described in detail here.

[0044] The guide assembly is provided in two sets, including a first guide bar 11 and a second guide bar 12, wherein the top end of the first guide bar 12 is fixedly connected to the back plate 6 and the bottom end is fixed to the back plate 6.

[0045] The first guide strips 11 of the two sets of guide components are respectively set on both sides of the back plate 6. The first guide strip 11 includes a first guide section, a second guide section, a third guide section and a fourth guide section arranged in sequence. The third guide section is arranged in the vertical direction. The second guide section and the third guide section form a set obtuse angle. The first guide section and the second guide section form a set obtuse angle. The first guide section is set below the walking wheel 2-1. The top of the first guide section is fixed to the back plate 6 by bolts. The fourth guide section is perpendicular to the third guide section. One end of the fourth guide section is connected to the third guide section, and the other end is provided with a bent part. The bent part is fixedly connected to the bottom end of the back plate 6 by bolts.

[0046] The second guide bar 12 of one guide component is fixed to a walking mechanism mounting frame 8, and the second guide bar 12 of another guide component is fixed to another walking mechanism mounting frame 8. The second guide bar 12 is positioned opposite to the corresponding first guide bar 11, and the second guide bar 12 and the corresponding first guide bar 11 are offset in the horizontal direction.

[0047] In this embodiment, the top end of the second guide bar 12 is fixedly connected to the bottom end of the corresponding walking mechanism mounting frame 8, and the second guide bar 12 is arranged parallel to the second guide segment of the first guide bar 11.

[0048] With this arrangement, a guide channel is formed between the first guide bar 12 and the second guide bar 11. The guide channel includes a first guide part, one end of which is connected to a second guide part extending below the walking mechanism 2, and the other end is connected to a third guide part with a gradually expanding structure.

[0049] Specifically, a second guide section is formed above the first guide segment of the first guide bar 11, a first guide section is formed between the second guide bar 12 and the second guide segment, and a third guide section with a gradually expanding structure is formed between the second guide bar 12 and the third guide segment.

[0050] A connecting strip is provided between the bottom ends of the two second guide strips 12 to connect the two second guide strips into a whole to prevent the wire from entering and causing misalignment.

[0051] When using a drone to deploy the entire repair device, the power transmission line is first passed through the third guide section. Since the third guide section adopts a gradually expanding structure, it is more convenient for the drone to operate. Then, the drone continues to drive the entire repair device to fall. Using the guiding effect of the first and second guide sections, the entire repair device is moved into place. The walking wheel 2-1 is located above the power transmission line. As the drone continues to drive the entire repair device to fall, the walking wheel 2-1 cooperates with the power transmission line.

[0052] Furthermore, the top end of the second guide bar 12 is detachably and fixedly connected to the walking mechanism mounting frame 8 by a fastener. The top end of the second guide bar is provided with a circular fixing hole. The fastener adopts existing bolts or spring pins, preferably spring pins 13.

[0053] In this way, the first guide bar 11 and the second guide bar 12 can be disassembled, making it convenient to carry the repair device.

[0054] In this embodiment, both the first and second lifting mechanisms are fixed to the bottom of the back plate 6. Therefore, the center of gravity of the entire repair device is located at the bottom, and when the two wheels 2-1 are used in conjunction with the power transmission line, the entire repair device can be stably installed on the power transmission line.

[0055] like Figures 15-19 As shown, the pusher mechanism 3 includes a storage compartment, which includes a lower cover plate 3-1, an upper cover plate 3-2, and a first side plate 3-3, a second side plate 3-4, a third side plate 3-5, and a fourth side plate 3-6 disposed between the upper cover plate 3-1 and the lower cover plate 3-2. The upper cover plate 3-2, the lower cover plate 3-1, the first side plate 3-3, the second side plate 3-4, the third side plate 3-5, and the fourth side plate 3-6 form a cavity for accommodating multiple repair pieces 14.

[0056] In this embodiment, the first side plate 3-3 and the second side plate 3-4 are arranged opposite to each other, and the third side plate 3-5 and the fourth side plate 3-6 are arranged opposite to each other.

[0057] The third side plate 3-5 is located near the back plate 6, and the upper and lower ends of the side plate are fixed with the body connecting block 3-7. The tablet storage compartment is fixedly connected to the back plate 6 through the body connecting block 3-7 and bolts.

[0058] The fourth side plate 3-6 is provided with two first linear guide rails 3-8. The first linear guide rails 3-8 are slidably connected to the gripper slider connecting plate 3-9 through the first slider 3-26. The gripper slider connecting plate 3-9 is fixedly connected to the bottom end of the first guide positioning plate 1-9 and the fourth guide positioning plate 1-12 of the gripper mechanism housing by bolts.

[0059] The first linear guide rail 3-8 guides the lifting and lowering motion of the gripper mechanism.

[0060] The first side plate 3-3 has a film placement opening 3-10, the shape of which matches the initial shape of the repair piece 14.

[0061] The top of the second side plate 3-4 is provided with a dispensing port that matches the initial shape of the repair patch 14 for ejecting the repair patch 14.

[0062] The storage compartment is equipped with multiple sliding shafts, which are optical shafts 3-11. The top end of the optical shaft 3-11 is fixed vertically to the upper cover plate 3-2, and the bottom end is fixed vertically to the lower cover plate 3-1.

[0063] Preferably, the storage compartment is equipped with four sliding shafts.

[0064] Four sliding shafts pass through the pressure block 3-12. The pressure block 3-12 is slidably connected to the sliding shafts via linear bearings and can move along the axis of the sliding shafts. A second elastic element is provided between the lower surface of the pressure block 3-12 and the lower cover plate. The second elastic element is a second spring 3-13 sleeved on the outer circumference of the sliding shaft. One end of the second spring 3-13 is connected to the lower cover plate 3-1, and the other end is connected to the lower surface of the pressure block 3-12. The shape of the upper surface of the pressure block 3-12 matches the initial shape of the repair piece 14 and is used to support the repair piece 14.

[0065] To facilitate the movement of the pressure block 3-12 to insert the repair patch 14, the pressure block 3-12 is connected to one end of the handle 3-14. The handle 3-14 extends out of the first side plate 3-3 through a vertical groove. The vertical groove communicates with the patch opening 3-10 and passes through the middle of the patch opening 3-10.

[0066] Specifically, the end of the handle 3-14 is fixedly connected to the pressure block 3-12 via the handle connecting block 3-15.

[0067] When in use, the operator pulls the handle 3-14 to move the pressure block 3-12 downward. The operator can then stack multiple repair pieces 14 on top of the pressure block 3-12 through the piece placement port 3-10.

[0068] The upper cover plate 3-2 is fixed with a pusher drive component, which is arranged opposite to the outlet. The pusher drive component is connected to a push block, which is used to cooperate with the repair piece. The pusher drive component can drive the push block to make linear motion, thereby pushing the repair piece out from the outlet.

[0069] like Figures 20-21 As shown, the pusher drive is a device capable of outputting linear motion, such as a lead screw drive mechanism, a cylinder, or an electric push rod. In this embodiment, the pusher drive is a lead screw drive mechanism, including a first lead screw motor 3-16. The first lead screw motor 3-16 is fixed to one end of the upper cover plate 3-2 via a motor base 3-17. The output shaft of the first lead screw motor 3-16 is connected to a lead screw, which is connected to a lead screw nut 3-18. The lead screw nut 3-18 is connected to a push block 3-19, and the push block 3-19 is slidably connected to a second linear guide rail 3-20 located on the bottom surface of the upper cover plate 3-2 via a second slider 3-27.

[0070] The first lead screw motor 3-16 drives the lead screw to rotate, which in turn drives the push block 3-19 to perform linear motion through the lead screw nut 3-18.

[0071] Furthermore, to limit the movement of the push block 3-19, a light-blocking plate 3-28 is provided at the bottom of the lead screw nut 3-18. A first photoelectric limit switch 3-21 and a second photoelectric limit switch 3-22 are respectively provided on both sides of the light-blocking plate 3-28. The first photoelectric limit switch 3-21 is fixed on the motor base 3-17, and the second photoelectric limit switch 3-22 is fixed on the first side plate 3-3. Both the first and second photoelectric limit switches 3-21 are connected to the control system, which is connected to the first lead screw motor 3-16. When the push block 3-19 moves towards... When the pusher moves towards the film outlet until the light-blocking plate 3-28 engages with the second photoelectric limit switch 3-22, it indicates that the pusher has completed its push. The second photoelectric limit switch 3-22 sends a signal to the control system, which then controls the first lead screw motor 3-16 to stop rotating and the pusher block 3-19 to stop moving. When the pusher block 3-19 moves away from the film outlet until the light-blocking plate 3-28 engages with the first photoelectric limit switch 3-21, it indicates that the pusher block 3-19 has completed its reset. The first photoelectric limit switch 3-21 sends a signal to the control system, which then controls the first lead screw motor 3-16 to stop working.

[0072] like Figures 22-23 As shown, the push block 3-19 includes a push block body, which has a channel for the lead screw connected to the first lead screw motor 3-16 to extend into. The shape of the push block body matches the initial shape of the repair piece 14. The push block body has a protrusion that matches the shape of the repair piece to divide the push block into a first push block part 3-19-1 located in front and a second push block part 3-19-2 located in the rear. The thickness of the protrusion is the same as the thickness of the repair piece 14. The stepped surface formed between the protrusion and the push block body is used to contact the side end face of the repair piece, thereby pushing the repair piece out.

[0073] The outer edge of the stepped surface is provided with a chamfered structure. In this embodiment, for example... Figure 23 As shown, the repair piece 14 to be pushed out is defined as the current repair piece, and the repair piece below the current repair piece is defined as the lower repair piece. With the setting of the chamfer structure, if the step surface pushes the current repair piece and also contacts the lower repair piece, the chamfer structure will generate a force on the lower repair piece to move it away from the step surface. This allows the second push block 3-19-2 of the push block 3-19 to replace the gap caused by the current repair piece 14 being pushed out, ensuring that the repair piece 14 is pushed out more smoothly and is not stuck.

[0074] In this embodiment, the repair piece 14 includes a first piece 14-1, a second piece 14-2 is provided at the center of one side of the first piece 14-1, and a third piece 14-3 is provided at both ends of the other side. Since only the parts of the second piece 14-2 and the third piece 14-3 that are pushed by the step surface will come into contact with the repair piece below during the process of pushing the repair piece 14, a chamfer is only made on the outer edge of the part of the step surface that mates with the second piece 14-2 and the third piece 14-3.

[0075] In this embodiment, in the initial state, the first push block 3-19-1 corresponds to the position of the repair piece 2, and the second push block 3-19-2 passes through the top of the first side plate 3-3.

[0076] Furthermore, the upper cover plate 3-2 is provided with a positioning hole 3-23 on the side near the gripper mechanism. Correspondingly, the top of the gripper mechanism housing is equipped with a positioning pin 1-32 that matches the positioning hole through a positioning pin mounting block 1-31. When the gripper mechanism descends, the positioning pin 1-32 can be inserted into the positioning hole 3-23, so that the distance between the gripper mechanism and the tablet storage compartment is maintained at a set distance, thus playing a positioning role.

[0077] In this embodiment, the second side plate 3-4 is provided with a first clearance groove 3-24, the top of the first clearance groove 3-24 extends to the plate outlet, and the first clearance groove 3-24 forms a space to accommodate the stop block mounting seat 1-29 in the gripper mechanism, so as to allow the stop block mounting seat 1-29 to pass. The bottom center of the protruding front end of the push block 3-19 is provided with a second clearance groove 3-25, which provides clearance space for the stop block 1-28 in the gripper mechanism.

[0078] The gripper mechanism can be the same as the gripper mechanism described in Example 1, and the requirement will not be repeated here. The housing of the gripper mechanism is connected to the first lifting mechanism, and the first lifting mechanism can drive the gripper mechanism to move up and down.

[0079] The first lifting mechanism adopts a device capable of outputting linear motion, such as an electric push rod or a lead screw lifting mechanism. In this embodiment, the first lifting mechanism adopts a lead screw lifting mechanism, including a second lead screw motor 15. The second lead screw motor 15 is fixed to the bottom of the back plate 6 through a motor base 16. The output shaft of the second lead screw motor 15 is connected to the lead screw. The lead screw is connected to the lead screw nut 1-35. The lead screw nut 1-35 is fixedly connected to the lower slider fixing block 1-33 on the gripper mechanism housing. The lower slider 1-34 is fixed to the housing through the lower slider fixing block 1-33. The gripper mechanism housing is also fixed with an upper slider through the slider fixing block 1-33. The upper slider and the lower slider 1-34 are slidably connected to two third linear guide rails 17 provided on the back plate 6. The second lead screw motor 15 can drive the lead screw to rotate, thereby causing the gripper mechanism to perform lifting motion.

[0080] Since the gripper mechanism achieves lifting and lowering movement through the upper and lower sliders, the body connecting block 3-7 of the third side plate 3-5 of the film storage compartment is provided with a notch to avoid the upper and lower sliders.

[0081] Furthermore, in order to limit the up and down movement of the gripper mechanism, a light-blocking plate 1-36 is fixed on the lower slider fixing block 1-33. A third photoelectric limit switch 18 is provided above the light-blocking plate 1-36, and a fourth photoelectric limit switch 19 is provided below the light-blocking plate 1-36. The third photoelectric limit switch 18 is fixed on the back plate 6, and the fourth photoelectric limit switch 19 is fixed at the bottom of the third side plate 3-5 near the back plate 6 in the chip storage compartment.

[0082] Both the third photoelectric limit switch 18 and the fourth photoelectric limit switch 19 are connected to the control system, which is connected to the second lead screw motor 15. When the light-blocking plate 1-36 of the lower slider moves upward with the gripper mechanism to engage with the third photoelectric limit switch 18, the third photoelectric limit switch 18 sends a signal to the control system, which then controls the second lead screw motor 15 to stop working. When the light-blocking plate 1-36 of the lower slider moves downward with the gripper mechanism to engage with the fourth photoelectric limit switch 19, the fourth photoelectric limit switch 19 sends a signal to the control system, which then controls the second lead screw motor 15 to stop working.

[0083] like Figure 25 As shown, the cable straightening mechanism 4 includes a cable straightening plate 4-1, a cable straightening groove on the top of the cable straightening plate 4-1, and a cable straightening sleeve 4-2 on the surface of the cable straightening groove. The cable straightening sleeve 4-2 is made of existing wear-resistant plastic material, such as POM plastic. A third slider 4-4 is fixed to the side of the cable straightening plate 4-1 near the back plate 6 through a slider connecting plate 4-3. The third slider 4-4 is slidably connected to the fourth linear guide rail 20 set on the back plate. A connecting block 4-5 is provided on the other side of the cable straightening plate 4-1. The connecting block 4-5 is connected to the second lifting mechanism.

[0084] The second lifting mechanism 21 adopts a device capable of outputting linear motion, such as an electric push rod, a cylinder, or a screw lifting mechanism. In this embodiment, the second lifting mechanism 21 adopts an electric push rod, which is fixed to the bottom of the back plate by a support 22, and its telescopic part is connected to the connecting block 4-5.

[0085] Furthermore, the top of the fixed part of the electric push rod is also fixed to the back plate 6 by a fixing bracket 23 to ensure the fixing strength of the electric push rod.

[0086] In this embodiment, the control system and the battery for powering the various devices are located inside the electronic compartment 5, which is fixed between two first guide bars 11 to protect the devices inside.

[0087] The working method of the power transmission line strand breakage repair device in this embodiment is as follows: like Figures 26-27 As shown, the hook at the bottom of the boom 10 of the drone 9 is connected to the hanging ring. The drone 9 lifts the broken strand repair device above the power line that needs to be repaired, so that the power line is located between the first guide bar 11 and the second guide bar 12. Then the drone 9 lowers the broken strand repair device. Under the guidance of the first guide bar 11 and the second guide bar 12, the power line will slide under the two traveling wheels 2-1 and cooperate with the traveling wheels 2-1. Then the drone 9 flies away.

[0088] After the drone 9 flies away, the second lifting mechanism 21 operates, placing the power transmission line into the straightening groove. Subsequently, the walking mechanism 2 operates, and the broken strand repair device moves along the power transmission line. After reaching the area that needs repair, the straightening groove first straightens the drooping broken strand of the power transmission line. The first lead screw motor 3-16 operates, and the push block 3-19 pushes the uppermost repair piece 14 into the gripper mechanism. Then, the push block 3-19 returns to its original position. At this time, under the action of the second spring 3-13, the repair piece 2 below the repair piece rises to fit against the surface of the first push block 3-19-1.

[0089] The first lifting mechanism drives the gripper mechanism to rise. After rising to the correct position, the telescopic component 1-2 of the gripper mechanism operates, using the first side pressure rod 1-7 to bend the third part 14-3 of the repair piece 14, and using the first middle pressure rod 1-4 to bend the second part 14-2 of the repair piece 14, so that the repair piece 14 wraps around the transmission line, completing one strand break repair. Then, the telescopic component 1-2 is reset, the first lifting mechanism and the second lifting mechanism 21 are reset, and after the gripper mechanism is reset, the positioning pin 1-32 is inserted into the positioning hole 3-23.

[0090] The repair device continues to travel along the transmission line, and can complete multiple repair processes.

[0091] The repair device of this embodiment utilizes drones or other flying equipment to coordinate the repair device with the power transmission line, eliminating the need for manual climbing or track construction, thus avoiding the risk of falling from heights and significantly reducing operational safety hazards. The hanging ring, the first guide bar 11, and the second guide bar 12 are detachable, significantly reducing the packaging volume and improving portability. It can carry multiple repair pieces 14, and a single loading can complete the repair work of multiple broken strands, significantly improving operational efficiency. It can adapt to various repair environments, including complex environments such as mountainous areas and forest areas that traditional broken strand repair equipment cannot reach.

[0092] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
