Description

Technical Field

[0001] The present invention relates to the field of electric power maintenance, and more particularly to a ground wire repairing robot. Background Art

[0002] The stability and reliability of the power system are crucial to ensuring socioeconomic activities and people's livelihoods. Within this system, high-voltage and ultra-high-voltage transmission lines, as core components of power transmission, ensure safe and stable operation, crucial for ensuring the quality of power supply. These transmission lines are often deployed outdoors and face constant challenges from the natural environment, including climate change, mechanical stress, external damage, and electrical flashovers. These factors can damage the ground wires, such as cracks and loose strands. This damage can reduce the transmission capacity of the transmission lines and, in severe cases, can even trigger electrical incidents such as short circuits, flashovers, and tripping, posing a threat to the stability of the power system.

[0012] Furthermore, the control mechanism includes a guide rod horizontally fixedly installed on the side wall of the liquid storage chamber, the guide rod extends into the oil outlet, a piston plate is provided on the sliding sleeve of the guide rod, the side wall of the piston plate is in contact with the side wall of the oil outlet, and an elastic part is installed between the piston plate and the side wall of the liquid storage chamber.

[0017] Furthermore, an elastic rope is fixedly installed in the air hole, and a collision block made of rubber material is fixedly installed on the elastic rope.

[0018] Compared with the prior art, the present invention has the following beneficial effects: (1) This solution uses the oil supply mechanism, cavity, sponge, and holes to cooperate with each other. Under the action of the oil supply mechanism, a large amount of lubricating oil is contained in the cavity, and the lubricating oil is discharged to the outside through the holes. At this time, the lubricating oil discharged from the holes is absorbed by the sponge and evenly spread on the surface of the sponge. When the splice is pulled out of the wire hole and passes through the annular sponge, the lubricating oil on the surface of the sponge will be smeared on the surface of the splice. As the gantry moves, the splice with lubricating oil on the surface will come into contact with the ground wire. Therefore, when the annular plate drives the splice to rotate and causes the splice to wrap around the surface of the ground wire, the friction between the splice and the ground wire can be reduced, thereby reducing the wear of the ground wire and preventing the surface of the ground wire from being damaged. This can protect the ground wire when it is repaired.

[0019] (2) In this solution, the air pipe and the air supply mechanism cooperate with each other, and the gas discharged from the air hole impacts the surface of the ground wire, so that the impurities attached to the surface of the ground wire can be knocked off by the air flow. When the splicing strip is wound, the friction force on the surface of the ground wire is reduced, thereby improving the protection effect of the ground wire.

[0020] (3) This solution uses the interaction of the elastic airbag, the air inlet valve, and the exhaust valve. When the elastic part recovers, the pressurized chamber draws air from the outside through the air inlet valve, and the pressurized chamber stops supplying air to the elastic airbag. At this time, the elastic airbag recovers, and the gas discharged during the recovery process of the elastic airbag is discharged through the air pipe and the air hole. Therefore, during the compression and recovery process of the elastic part, the air hole can continuously exhaust gas, thereby improving the cleaning effect of the ground wire.

[0021] (4) In this solution, the elastic rope and the impact block cooperate with each other. The gas discharged from the air hole impacts the impact block. At this time, the impact block impacts the ground wire, which can cause the ground wire to vibrate slightly and shake off the impurities attached to the surface of the ground wire, thereby improving the cleaning effect of the ground wire surface.

[0024] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0025] Example 1 See also Figures 1 to 10 , a ground wire repair robot, comprising a gantry 1, the gantry 1 being provided with a first driving mechanism for driving the gantry 1 to move; A mounting frame 2 is commonly installed between the inner side walls on opposite sides of the gantry 1. The mounting frame 2 is provided with a circular hole 201. A socket 202 communicating with the outside world is opened on the side wall of the circular hole 201. A circular ring plate 3 is rotatably installed on the side wall of the mounting frame 2. A through hole 301 cooperating with the socket 202 is opened on the side wall of the circular ring plate 3. The through hole 301 passes through the inner and outer ring sides of the circular ring plate 3. During operation, the socket 202 is aligned with the through hole 301 to allow the ground wire to enter the center of the circular ring plate 3. Wire holes 302 are evenly opened on the inner ring side of the circular ring plate 3, and a pressurizing mechanism is provided in the wire holes 302. A second driving mechanism for driving the circular ring plate 3 to rotate is provided on the mounting frame 2. A cavity 4 is provided on the annular plate 3, and a hole 5 communicating with the outside is provided on the side wall of the cavity 4. A sponge 6 is fixedly installed on the side wall of the annular plate 3. The sponge 6 is annular, and an opening 7 that cooperates with the wire hole 302 is provided on the side wall of the sponge 6. When the connecting strip passes through the wire hole 302, the connecting strip also passes through the opening 7 into the interior of the annular sponge 6, and an oil supply mechanism for providing lubricating oil to the cavity 4 is provided on the gantry 1.

[0026] The first driving mechanism includes a roller 8 and a support wheel 9 rotatably mounted on the side wall of the gantry 1, wherein the rotating shaft of the roller 8 and the rotating shaft of the support wheel 9 are located in the same plane, and the rotating shaft of the roller 8 and the rotating shaft of the support wheel 9 are parallel to each other, and an annular clamping groove 10 is provided on the outer ring side of the roller 8 and the support wheel 9; a first motor 11 for driving the roller 8 to rotate is fixedly mounted on the gantry 1, wherein the output end of the first motor 11 is fixedly connected to the rotating shaft of the roller 8; thereby, the roller 8 is driven to rotate by the first motor 11; at this time, under the action of the friction between the roller 8 and the ground wire, the gantry 1 can be driven to move, thereby playing the role of driving the gantry 1 to move; The second driving mechanism includes an arcuate groove 12 formed on the side wall of the mounting frame 2. Sliders 13 are evenly fixedly mounted on the side wall of the annular plate 3. The spacing between two adjacent slides 13 is the same, and the slides 13 are slidably mounted in the arcuate groove 12. The spacing between two adjacent slides 13 is greater than the spacing between the side walls of the through hole 301. Therefore, when one of the slides 13 is located in the through hole 301, the remaining slides 13 remain in the arcuate groove 12. Two mounting rods 14 are rotatably mounted on the side walls of the mounting frame 2. Gears 16 are fixedly mounted at the ends of the mounting rods 14. Tooth grooves 15 are evenly formed on the outer wall of the annular plate 3. Each gear 16 meshes with the tooth grooves 15. Therefore, when the two gears 16 rotate synchronously, the annular plate 3 can be driven to rotate via the tooth grooves 15. A sprocket 17 is mounted on the mounting rods 14. A chain 18 is mounted on the two sprockets 17, and the chain 18 meshes with the sprockets 17. A second motor 19 is fixedly mounted on the mounting frame 2 for driving the mounting rods 14 to rotate. The output end of the second motor 19 is fixedly connected to the rotating shaft of one of the mounting rods 14. Therefore, when the second motor 19 drives the mounting rods 14 to rotate, the chain 18 and the sprocket 17 cause the two mounting rods 14 to rotate synchronously, i.e., the two gears 16 rotate synchronously, thereby driving the annular plate 3 to rotate. The cooperation between the sprocket 17 and the chain 18 is conventional and will not be described in detail.

[0027] First, place the roller 8 and the support wheel 9 above the ground wire, and make the slots 10 on the roller 8 and the support wheel 9 stuck outside the ground wire. At this time, under the limiting effect of the slots 10, the gantry 1 can be suspended on the ground wire.

[0028] Then manually insert the connecting strip into the wire hole 302, and apply pressure to the connecting strip through the pressure mechanism to increase the friction between the connecting strip and the side wall of the wire hole 302, ensuring that the rotating annular plate 3 can drive the connecting strip to rotate.

[0029] Then, the first driving mechanism and the second driving mechanism are started, so that the annular plate 3 is rotated while the gantry 1 moves along the ground wire.

[0030] At the same time, under the action of the oil supply mechanism, a large amount of lubricating oil is contained in the cavity 4, and the lubricating oil is discharged to the outside through the hole 5. At this time, the lubricating oil discharged from the hole 5 is absorbed by the sponge 6 and evenly spread on the surface of the sponge 6.

[0031] When the connecting strip is pulled out from the wire hole 302 and passes through the annular sponge 6, the lubricating oil on the surface of the sponge 6 will be smeared on the surface of the connecting strip. As the gantry 1 moves, the connecting strip with lubricating oil on the surface will contact the ground wire. Therefore, when the annular plate 3 drives the connecting strip to rotate and wraps the connecting strip around the surface of the ground wire, the friction between the connecting strip and the ground wire can be reduced, thereby reducing the degree of wear of the ground wire and preventing damage to the surface of the ground wire, thereby protecting the ground wire when repairing the ground wire.

[0032] like Figure 5As shown, the pressure mechanism includes a threaded rod 20 fixedly mounted on the side wall of the wire hole 302, the threaded rod 20 is parallel to the straight line of the diameter of the circular ring plate 3, a nut 21 is threadedly mounted on the threaded rod 20, and a pressure plate 22 is movably sleeved on the threaded rod 20, an elastic pad 23 is fixedly mounted on the side wall of the pressure plate 22 close to the wire hole 302, and the pressure plate 22 is located between the nut 21 and the wire hole 302.

[0033] After the connecting strip is placed in the wire hole 302, the nut 21 is turned so that the nut 21 pushes the pressure plate 22 into the wire hole 302 until the pressure plate 22 applies pressure to the connecting strip and the elastic pad 23 is deformed. At this time, the nut 21 is stopped from being turned, so that the connecting strip in the wire hole 302 can be pressurized to ensure that the rotating annular plate 3 can drive the connecting strip to be wound around the surface of the ground wire. At the same time, under the action of the elastic pad 23, when the gantry 1 moves, the connecting strip can be pulled through the wire hole 302.

[0034] like Figure 7 As shown, the oil supply mechanism includes a liquid storage chamber 24 provided on the mounting frame 2, and the liquid storage chamber 24 is filled with lubricating oil; An oil outlet 25 is provided on the side wall of the liquid storage chamber 24 close to the annular plate 3; An oil inlet 26 is provided on the side wall of the cavity 4 near the mounting frame 2. The oil outlet 25 cooperates with the oil inlet 26. Therefore, as the annular plate 3 rotates, the oil outlet 25 is connected to the oil inlet 26 once each time the annular plate 3 rotates one circle. The oil outlet 25 is provided with a control mechanism for controlling the flow of lubricating oil from the liquid storage chamber 24 into the oil outlet 25. When the oil outlet 25 is connected to the oil inlet 26, the control mechanism controls the flow of lubricating oil from the liquid storage chamber 24 into the oil outlet 25. At this time, the lubricating oil in the oil outlet 25 flows into the oil inlet 26, and then flows through the one-way valve 30 into the cavity 4, thereby providing lubricating oil to the cavity 4.

[0035] like Figure 7 、 Figure 8 As shown, the control mechanism includes a guide rod 27 horizontally fixedly mounted on the side wall of the liquid storage chamber 24, the guide rod 27 extends into the oil outlet 25, a piston plate 28 is slidingly sleeved on the guide rod 27, the side wall of the piston plate 28 is in contact with the side wall of the oil outlet 25, and an elastic member 29 is installed between the piston plate 28 and the side wall of the liquid storage chamber 24.

[0036] A one-way valve 30 and a magnet 31 are fixedly installed in the oil inlet 26. The magnet 31 and the piston plate 28 repel each other. By setting the one-way valve 30, the lubricating oil in the cavity 4 can be prevented from flowing out through the oil inlet 26 when the oil inlet 26 is out of contact with the side wall of the mounting frame 2, thereby saving costs.

[0037] When the elastic member 29 is in a naturally stretched state, the piston plate 28 is located in the oil outlet 25 . At this time, the oil outlet 25 is blocked, thereby preventing the lubricating oil in the liquid storage chamber 24 from leaking.

[0038] When the oil inlet 26 is connected to the oil outlet 25, the magnet 31 approaches the piston plate 28. At this time, under the action of the repulsive force, the piston plate 28 moves along the guide rod 27 and gradually loses contact with the oil outlet 25, and the elastic member 29 is gradually squeezed. When the piston plate 28 loses contact with the oil outlet 25, the oil outlet 25 is connected to the liquid storage chamber 24. At this time, the liquid storage chamber 24 can discharge the lubricating oil through the oil outlet 25.

[0039] Therefore, when the through hole 301 covers the surface of the oil outlet 25 , leakage of the lubricating oil in the liquid storage chamber 24 can be prevented.

[0040] like Figure 3 As shown, a connecting rod 32 is vertically fixedly installed on the inner top wall of the gantry 1, and an arc-shaped air pipe 33 is fixedly installed on the bottom end of the connecting rod 32. The air pipe 33 is made of elastic material, and both ends of the air pipe 33 are sealed. The distance between the two ends of the air pipe 33 is 1 mm, and air holes 34 are evenly opened on the side wall of the air pipe 33, and an air supply mechanism for supplying air to the air pipe 33 is provided on the mounting frame 2.

[0041] An elastic airbag 35 is fixedly mounted on the side wall of the connecting rod 32 . The output end of the elastic airbag 35 extends into the trachea 33 , so the output end of the elastic airbag 35 is in communication with the trachea 33 .

[0042] The air supply mechanism includes a pressurized chamber 36 opened on the elastic member 29, and an air intake valve 37 and an exhaust valve 38 are embedded on the side wall of the pressurized chamber 36. The output end of the exhaust valve 38 is connected to the input end of the elastic airbag 35, and the input end of the air intake valve 37 passes through the side wall of the liquid storage chamber 24 and is connected to the outside world.

[0043] During operation, the arc-shaped air tube 33 is sleeved on the outside of the ground wire of the connecting strip to be wound, and the elastic member 29 is intermittently squeezed.

[0044] During the compression of the elastic member 29, the gas in the pressurized chamber 36 is discharged into the elastic airbag 35 through the exhaust valve 38. At this time, part of the gas is discharged to the outside through the output end of the elastic airbag 35 and the air hole 34 on the trachea 33, and part of the gas remains in the elastic airbag 35 to expand the elastic airbag 35.

[0045] The gas discharged from the air hole 34 impacts the surface of the ground wire, so that impurities attached to the surface of the ground wire can be knocked off by the airflow. When the splicing strip is wound, the friction on the surface of the ground wire is reduced, thereby improving the protection effect of the ground wire.

[0046] When the elastic member 29 recovers, the pressurized chamber 36 draws air from the outside through the air inlet valve 37, and the pressurized chamber 36 stops supplying air to the elastic airbag 35. At this time, the elastic airbag 35 recovers, and the gas discharged during the recovery process of the elastic airbag 35 is discharged through the air pipe 33 and the air hole 34. Therefore, during the compression and recovery process of the elastic member 29, the air hole 34 can continue to exhaust air, thereby improving the cleaning effect of the ground wire.

[0047] like Figure 9 As shown, an elastic cord 39 is fixedly mounted in the air hole 34, and a rubber impact block 40 is fixedly mounted on the elastic cord 39. The gas discharged from the air hole 34 impacts the impact block 40, which then strikes the ground wire, causing the ground wire to vibrate slightly, shaking off impurities adhering to the ground wire surface and improving the cleaning effect of the ground wire surface. Furthermore, the elastic material of the impact block 40 prevents damage to the ground wire, thus protecting the ground wire.

[0048] The above are only preferred embodiments of the present invention; however, the scope of protection of the present invention is not limited thereto. Any person skilled in the art who, within the technical scope disclosed by the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
