Description

Technical Field

[0001] This invention relates to the field of automatic grounding wire attachment and removal technology, and in particular to an automatic grounding wire attachment and removal device based on an opposite double claw structure. Background Technology

[0002] When performing power outage maintenance on the power grid, in order to prevent the power grid lines from being suddenly powered on or from induced voltage generated by nearby high-voltage equipment, which could cause harm to the construction personnel, it is usually necessary to test the line for voltage before construction and connect the grounding wire to the power grid line. During construction, the grounding wire must be kept connected to the power grid line. The power grid line is usually an overhead line and usually consists of three parallel three-phase conductors. During construction, all three conductors must be kept connected to the grounding wire.

[0003] In existing technology, the work of attaching and detaching grounding wires from power grid lines is usually done manually by workers. Workers typically use an insulated rod to lift the clamps of the grounding wire onto the three-phase conductors, and after the work is completed, they use the insulated rod to remove the clamps of the grounding wire from the three-phase conductors.

[0004] However, it is worth considering that during the process of hanging and removing the grounding wire, the grounding wire is fixedly installed on the grounding wire clamp. When the height of the three-phase conductors is relatively high, a longer grounding wire is required, which increases the weight of the insulating rod and may even require multiple people to cooperate. It is not convenient to control the insulating rod to suspend the grounding wire clamp on the three-phase conductors, and the lifting of heavy objects is also prone to loss of force, which poses certain safety hazards.

[0005] Therefore, in order to solve the above problems, a more suitable facility that meets the needs of users is needed. Summary of the Invention

[0006] In view of this, the purpose of this invention is to propose an automatic grounding wire hanging and unhanging device based on an opposite double-claw structure, so as to solve the problems mentioned above, when the height of the three-phase conductors is high, the weight of the supporting insulating rod is increased, it is not convenient to control the insulating rod to suspend the clamp of the grounding wire on the three-phase conductors, and the lifting of heavy objects is also prone to loss of force.

[0020] The beneficial effects of this invention are as follows: The operator places the base at the preset grounding wire position.

The operator then fixes the end of the grounding wire onto the conductive sleeve. The lifting and detaching structure on the base drives the locking sleeve upwards. The locking sleeve slides outside the insulating tube, causing the locking sleeve to automatically move the conductive sleeve and grounding wire upwards. When the conductive sleeve is fitted over the conductive seat, the locking structure secures the locking sleeve and conductive seat together. Furthermore, the conductive connector electrically connects the inner wall of the conductive sleeve and the outer wall of the conductive seat. The automatic suspension of the grounding wire is completed. After construction, the locking structure releases the fixed relationship between the locking sleeve and the conductive seat. The lifting and dismantling structure drives the locking sleeve, conductive sleeve, and grounding wire to move downward relative to the insulating tube, ultimately allowing the grounding wire to be retrieved to the ground. The operator then drives the conductive seat and grounding conductive hook to move through the insulating tube, so that the grounding conductive hook is no longer suspended on the three-phase conductors. The operator does not need to directly suspend the grounding wire on the three-phase conductors through the insulating rod, eliminating the need to consider the problem of manually lifting the grounding wire. This facilitates the suspension of the grounding wire at a high place, and does not require the cooperation of multiple people. A single person can complete the automatic suspension of the grounding wire, reducing labor intensity and danger. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0025] Example 1, by Figure 1 , Figure 2 , Figure 4 and Figure 10The present invention includes a base 1 and a grounding conductive hook 2 for suspending on a three-phase conductor 3. The bottom end of the grounding conductive hook 2 is fixedly connected to a conductive seat 4. Several insulating tubes 5 are arranged vertically in sequence below the conductive seat 4. The bottom end of the conductive seat 4 is fixedly connected to the top end of the uppermost insulating tube 5. Adjacent insulating tubes 5 can be detached and connected by a disassembly and assembly component. A conductive sleeve 6, compatible with a conductive base 4, is provided above the base 1. A locking sleeve 7 is fixedly connected to the bottom end of the conductive sleeve 6. A conductive connector compatible with the conductive base 4 is provided inside the conductive sleeve 6. A locking structure compatible with the conductive base 4 is installed on the locking sleeve 7. A lifting and detaching structure for driving the locking sleeve 7 to slide outside the insulating tube 5 is installed on the base 1. The operator places the base 1 at the preset grounding wire position. The operator drives the conductive base 4 and the grounding conductive hook 2 to move through the insulating tube 5, so that the grounding conductive hook 2 is suspended on the three-phase conductor 3. The operator then fixes the end of the grounding wire to the conductive sleeve 6. The lifting and detaching structure on the base 1 drives the locking sleeve 7 to move upward. The locking sleeve 7 slides outside the insulating tube 5, so that the locking sleeve 7 drives the conductive sleeve 6 and the grounding wire to move upward automatically. When the conductive sleeve 6 is fitted outside the conductive base 4... The locking sleeve 7 and the conductive base 4 are fixedly connected together by a locking structure, and the conductive connector connects the inner wall of the conductive sleeve 6 and the outer wall of the conductive base 4 in a conductive manner, thus completing the automatic suspension of the grounding wire. After the construction is completed, the locking structure releases the fixed relationship between the locking sleeve 7 and the conductive base 4, and the locking sleeve 7, the conductive sleeve 6 and the grounding wire are driven to move down relative to the insulating tube 5 through the lifting and dismantling structure, so that the grounding wire is finally retrieved to the ground. The operator then drives the conductive base 4 and the grounding conductive hook 2 to move through the insulating tube 5, so that the grounding conductive hook 2 is no longer suspended on the three-phase conductor 3. The operator does not need to directly suspend the grounding wire on the three-phase conductor 3 through the insulating rod, and there is no need to consider the problem of manually lifting the grounding wire. It is convenient to suspend the grounding wire at a high place, and no multiple people are needed. A single person can complete the automatic suspension of the grounding wire, reducing labor intensity and danger.

[0026] Example 2, based on Example 1, is... Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 10 , Figure 11 and Figure 12The lifting and dismantling structure includes a mounting base 54 and a lifting box 8 disposed above the base 1. The base 1 is equipped with an angle adjustment mechanism for adjusting the tilt angle of the mounting base 54. The mounting base 54 is equipped with a flipping unit for flipping the lifting box 8. A connecting rod 9 passes through the lifting box 8. Iron columns 10, matching the inner diameter of the insulating tube 5, are fixedly connected to both ends of the connecting rod 9. The diameter of the connecting rod 9 is the same as the outer diameter of the insulating tube 5. Lifting units, respectively matching the connecting rod 9 and the insulating tube 5, are installed on the lifting box 8. A drive mechanism is installed on the mounting base 54. The drive unit for moving the docking rod 9 includes a conductive connector comprising two conductive brushes 11 disposed within a conductive sleeve 6. Two first sliding grooves 12 adapted to the conductive brushes 11 are formed on the inner wall of the conductive sleeve 6. The conductive brushes 11 are located within the corresponding first sliding grooves 12. Several compression springs 15 are provided between the conductive brushes 11 and the locking sleeve 7. Several first receiving grooves 13 are formed at the bottom of the conductive brushes 11, and several second receiving grooves 14 are formed at the top of the locking sleeve 7. The two ends of the compression springs 15 are fixedly connected to the corresponding first receiving grooves 13 and second receiving grooves 14, respectively. The locking structure includes pawls 16 respectively disposed on both sides of the locking sleeve 7. A first fixed shaft 17 is rotatably connected to the pawls 16, and the first fixed shaft 17 is fixedly connected to the locking sleeve 7. A torsion spring 18 is sleeved on the outside of the first fixed shaft 17, and the two ends of the torsion spring 18 are fixedly connected to the pawls 16 and the locking sleeve 7 respectively. Clearance holes 20 are respectively opened on the inner walls of both sides of the locking sleeve 7. A locking block 19 is provided above the pawls 16, and the locking block 19 passes through the corresponding clearance hole 20. A second fixed shaft 21 is fixedly connected to the locking block 19. A locking block 21 is opened at the top of the pawls 16. The second fixed shaft 21 passes through the corresponding waist-shaped hole 22. The side wall of the conductive seat 4 is provided with an annular groove 23 that is adapted to the locking block 19. The end of the locking block 19 away from the claw 16 is provided with an inclined surface that is adapted to the conductive seat 4. One end of the lifting box 8 is provided with an annular support groove 24 that is adapted to the claw 16. The other end of the lifting box 8 is provided with an annular chamber 26. The inner wall of the annular chamber 26 away from the annular support groove 24 is provided with a guide hole 25. The inner wall of the guide hole 25 is provided with an inclined surface that is adapted to the claw 16. After the base 1 is fixedly placed in the preset position, the conductive sleeve 6 and locking sleeve 7 are fitted onto the outside of the connecting rod 9. The bottom end of the claw 16 is located in the annular groove 24. The operator adjusts the angle of the insulating tube 5, and the operator also adjusts the angle of the mounting base 54 and the connecting rod 9 through the angle adjustment mechanism, so that the connecting rod 9 and the insulating tube 5 are on the same straight line. The connecting rod 9 is driven to move by the drive unit, so that an iron column 10 located above is inserted into the insulating tube 5. At this time, the insulating tube 5 and the connecting rod 9 are kept on the same straight line. The lifting unit drives the lifting box 8 to move relative to the connecting rod 9, so that the lifting box 8 slides from the outside of the connecting rod 9 to the outside of the insulating tube 5, and the lifting box 8 drives the conductive sleeve 6 and locking sleeve 7 to slide from the outside of the connecting rod 9 to the outside of the insulating tube 5. Externally, when the lifting box 8 drives the conductive sleeve 6 and locking sleeve 7 to slide to the preset height, the inclined surface on the locking block 19 contacts the conductive seat 4. As the locking sleeve 7 continues to move upward, the locking block 19 slides relative to the clearance hole 20, increasing the distance between the two locking blocks 19. The locking block 19 drives the second fixed shaft 21 to slide within the oblong hole 22, and the pawl 16 rotates relative to the first fixed shaft 17, changing the angle of the pawl 16. The torsion spring 18 undergoes elastic deformation. At this time, the conductive brush 11 contacts the inner wall of the conductive sleeve 6 and the side wall of the conductive seat 4, respectively, and the compression spring 15 is in a compressed state. When the conductive sleeve 6 and locking sleeve 7 move to the highest position, the locking block 19 moves to one side of the annular groove 23, and the torsion spring 18 drives the pawl 16 to rotate in the opposite direction. The chuck 16 can drive the locking block 19 to move in the opposite direction via the second fixed shaft 21, so that the end of the locking block 19 away from the chuck 16 is inserted into the annular groove 23. This fixes the conductive sleeve 6 and the locking sleeve 7 relative to the conductive seat 4, and the compression spring 15 applies an upward force to the conductive brush 11, so that the conductive brush 11 is tightly attached to the inner wall of the conductive sleeve 6 and the side wall of the conductive seat 4, respectively, ensuring that the conductive seat 4 and the conductive sleeve 6 can conduct electricity. After the grounding wire is suspended, the lifting unit drives the lifting box 8 to move down to the initial position. The lifting box 8 is detached from the outside of the insulating tube 5, and the tilt angle of the insulating tube 5 is limited by the connecting rod 9 and the iron column 10 to reduce the possibility of the insulating tube 5 shaking during construction. It is necessary to perform a cleaning of the conductive sleeve 6 and the grounding wire. During dismantling, the drive unit moves the docking rod 9 to disengage the upper iron column 10 from the insulating tube 5, terminating the connection between the docking rod 9 and the insulating tube 5. The flipping unit then drives the lifting box 8 and the docking rod 9 to rotate 180 degrees, positioning the guide hole 25 above the annular groove 24. Similarly, the drive unit again moves the docking rod 9 to align it with the insulating tube 5. The lifting unit then drives the lifting box 8 to slide from the outside of the docking rod 9 to the outside of the insulating tube 5. When the lifting box 8 moves below the locking sleeve 7, the bottom end of the chuck 16 contacts the inclined surface of the guide hole 25. As the lifting box 8 continues to move upward, the inner wall of the guide hole 25 pushes the chuck 16 to rotate, changing its tilt angle.This allows the claw 16 to drive the end of the locking block 19 to disengage from the annular groove 23 via the second fixed shaft 21, releasing the fixed relationship between the locking sleeve 7 and the conductive seat 4. As the lifting box 8 continues to move upward, the bottom end of the claw 16 slides into the annular chamber 26 and engages within it, while the bottom end of the locking block 19 remains detached from the annular groove 23. At this point, as the lifting box 8 moves downward, it can drive the locking sleeve 7, conductive sleeve 6, and grounding wire to move downward relative to the insulating tube 5 via the claw 16. Finally, the grounding wire is retrieved to the ground, and the operator can then drive the conductive seat 4 and the grounding conductive hook 2 to move via the insulating tube 5, allowing the grounding conductive hook 2 to detach from the three-phase conductor 3. This automatically completes the attachment and detachment of the grounding wire, improving convenience.

[0027] Example 3, based on Example 2, by Figure 9 and Figure 12 The assembly and disassembly components include connecting posts 55 disposed between two adjacent insulating tubes 5. The diameter of the connecting posts 55 is the same as the outer diameter of the insulating tubes 5. Threaded posts 56 are fixedly connected to both ends of the connecting posts 55. The threaded posts 56 are located inside the corresponding insulating tubes 5, and the inner wall of the insulating tubes 5 is provided with threads that are compatible with the threaded posts 56. The lifting unit includes at least two sets of climbing components disposed in the lifting box 8. Each set of climbing components includes two rotating shafts 27 rotatably mounted in the lifting box 8. Friction wheels 28 are fixedly sleeved on the outside of the rotating shafts 27, and the friction wheels 28 are in contact with the docking rods 9. Gears 30 are fixedly connected to the rotating shafts 27, and two adjacent gears 30 mesh with each other. At least two first servo motors 29 are fixedly connected inside the lifting box 8, and the number of first servo motors 29 is the same as the number of climbing components. The output end of the first servo motor 29 is fixedly connected to the corresponding rotating shaft 27. The operator drives the connecting post 55 and the threaded post 56 to rotate, so that one of the threaded posts 56 above the connecting post 55 is screwed into the corresponding insulating tube 5. The operator drives the connecting post 55 and the threaded post 56 to rotate again, so that one of the threaded posts 56 below the connecting post 55 is screwed into the other corresponding insulating tube 5, thus connecting the two adjacent insulating tubes 5. The first servo motor 29 is started, and the first servo motor 29 drives the corresponding rotating shaft 27 to rotate. The rotating shaft 27 drives the other corresponding rotating shaft 27 to rotate in the opposite direction through two gears 30. The rotating shaft 27 drives the friction wheel 28 to rotate. Through the opposite rotation of the two friction wheels 28, the two adjacent friction wheels 28 roll and rise on the docking rod 9 or the insulating tube 5, thus realizing the lifting of the lifting box 8.

[0028] Example 4, based on Example 2, by Figure 10 , Figure 11 , Figure 12 , Figure 13 and Figure 16The flipping unit includes a fixed sleeve 31 fixedly sleeved outside the lifting box 8. A lifting ring 32 is slidably sleeved on the outside of the fixed sleeve 31. Several second sliding grooves 33 are formed on the outer wall of the fixed sleeve 31. A slider 34 is slidably arranged in the second sliding grooves 33, and the slider 34 and the lifting ring 32 are fixedly connected. Clamping plates 35 are respectively provided on both sides of the fixed sleeve 31. A translation and rotation device for driving the clamping plates 35 to translate and rotate is installed on the mounting base 54. The translation and rotation device includes a second servo motor 37 respectively arranged on the side of the two clamping plates 35 that are far apart. The output end of the second servo motor 37 is fixedly connected to the corresponding clamping plate 35. Two mounting brackets 36 are fixedly connected to the top of the base 54. Several first hydraulic telescopic rods 38 are fixedly connected to the mounting brackets 36, and the telescopic ends of the first hydraulic telescopic rods 38 are fixedly connected to the corresponding second servo motors 37. The drive unit includes a movable frame 39 set above the mounting base 54. A second hydraulic telescopic rod 40 is fixedly connected to the mounting base 54, and the telescopic ends of the second hydraulic telescopic rod 40 are fixedly connected to the movable frame 39. A positioning sleeve 41 is fixedly connected to the movable frame 39, and the inner diameter of the positioning sleeve 41 is the same as the diameter of the iron column 10. An electromagnet 42 adapted to the iron column 10 is fixedly connected inside the positioning sleeve 41. When the lifting box 8 moves from the outside of the insulating tube 5 to the outside of the docking rod 9, the lifting box 8 drives the lifting ring 32 to contact the top of the clamping plate 35. As the lifting box 8 continues to move, the lifting box 8 moves downward relative to the lifting ring 32, and the slider 34 slides in the second slide groove 33 until the lifting box 8 moves downward relative to the docking rod 9 to the initial position. The top of the slider 34 contacts the top of the inner wall of the second slide groove 33. The first hydraulic telescopic rod 38 drives the second servo motor 37 and the clamping plate 35 to move relative to the lifting ring 32. Finally, the two clamping plates 35 clamp the fixing sleeve 31, so that the clamping... Plate 35 is fixed relative to fixed sleeve 31 and lifting box 8. At this time, the iron column 10 above the docking rod 9 is located inside the insulating tube 5, and the iron column 10 below the docking rod 9 is located inside the positioning sleeve 41. The iron column 10 below the docking rod 9 and electromagnet 42 are magnetically attracted. The movable frame 39 and positioning sleeve 41 are driven to move downward by the second hydraulic telescopic rod 40. Electromagnet 42 can then drive docking rod 9 and iron column 10 to move, so that the iron column 10 above docking rod 9 is disengaged from insulating tube 5. When docking rod 9 moves downward relative to lifting box 8 to the preset position, electromagnet 42 is de-energized. When the electromagnet 42 is no longer magnetically attracted to the iron column 10, the second hydraulic telescopic rod 40 drives the movable frame 39 and the positioning sleeve 41 to move continuously downward, causing the corresponding iron column 10 to disengage from the positioning sleeve 41. The second servo motor 37 then drives the clamping plate 35 to rotate 180 degrees, which in turn drives the fixed sleeve 31 and the lifting box 8 to rotate 180 degrees. At this point, the second hydraulic telescopic rod 40 again drives the movable frame 39 and the positioning sleeve 41 to move, so that the iron column 10 located below the docking rod 9 is inserted into the positioning sleeve 41. As the positioning sleeve 41 continues to move, the positioning sleeve... 41. Push the docking rod 9 and the iron column 10 upward relative to the lifting box 8 so that the iron column 10 located above the docking rod 9 is inserted into the insulating tube 5 again. At this time, the docking rod 9 and the insulating tube 5 are on the same straight line. The second servo motor 37 and the clamping plate 35 are driven to move by the first hydraulic telescopic rod 38 so that the clamping plate 35 no longer clamps the fixed sleeve 31 and the clamping plate 35 is no longer located directly above the lifting ring 32, so as to avoid the clamping plate 35 interfering with the upward movement of the lifting ring 32 and the fixed sleeve 31. At this time, the lifting unit can drive the lifting box 8 to move from the outside of the docking rod 9 to the outside of the insulating tube 5.

[0029] Example 5, based on Example 4, by Figure 10 , Figure 11 , Figure 13 , Figure 14 and Figure 15The mounting bracket 36 is rotatably connected to an iron plate 43. The end of the iron plate 43 away from the mounting bracket 36 is fixedly connected to a straightening plate 44 adapted to the insulating tube 5. The top of the mounting bracket 36 is fixedly connected to a magnet block 45 adapted to the iron plate 43. The angle adjustment mechanism includes a support bracket 46 fixedly mounted on the base 1. The bottom of the mounting base 54 is fixedly connected to a rotating ball 47. The support bracket 46 is provided with a receiving hole 48 adapted to the rotating ball 47. The base 1 is equipped with a positioner adapted to the rotating ball 47. The positioner includes a third hydraulic telescopic rod 50 fixedly mounted on the base 1. The telescopic end of the third hydraulic telescopic rod 50 is fixedly connected to a friction plate 49 located above the base 1. The top of the friction plate 49 is provided with a positioning groove 51 adapted to the rotating ball 47, and the rotating ball 47 and the positioning groove 51 are in contact. Several insert rods 52 pass through the base 1. The top of the insert rods 52 is fixedly connected to a fixing plate 53. The operator drives the iron plate 43 to rotate relative to the mounting bracket 36. The iron plate 43 drives the straightening plate 44 to move. The operator also drives the mounting base 54 and the rotating ball 47 to rotate relative to the receiving hole 48 through the iron plate 43 and the mounting bracket 36, changing the angle of the mounting base 54 and the connecting rod 9. The operator also adjusts the angle of the insulating tube 5. Finally, the two straightening plates 44 clamp the insulating tube 5, correcting its position so that the insulating tube 5 and the connecting rod 9 are on the same straight line. The iron plate 43 contacts the corresponding magnet block 45 and is fixed relative to the magnet block 45. The insulating tube 5 and the connecting rod 9 are on the same straight line. This is achieved through the third hydraulic telescopic rod 50. The friction plate 49 is moved so that the inner wall of the positioning groove 51 presses against the rotating ball 47, which fixes the mounting base 54 relative to the base 1, so that the mounting base 54 and the connecting rod 9 maintain a preset tilt angle. The operator drives the iron plate 43 to rotate relative to the mounting frame 36 to avoid the straightening plate 44 interfering with the movement of the lifting box 8. At this time, the other side of the iron plate 43 and the magnet block 45 are in contact, so that the iron plate 43 is fixed relative to the mounting frame 36. When the base 1 is placed on an uneven soil surface, the operator drives the fixing plate 53 and the insertion rod 52 through the base 1, and the insertion rod 52 is inserted into the soil. The design of the insertion rod 52 and the fixing plate 53 increases the stability of the base 1 when it is placed.
