Description

Technical Field

[0001] The invention relates to the technical field of grounding inspection and hooking devices, and in particular to an automatic grounding wire assembly and disassembly device. Background Art

[0002] High-voltage testers are indispensable safety measurement tools in the process of power transmission line and electrical equipment inspection and testing. The accuracy of its testing and the correctness of its operation are of great significance to ensuring the safety of on-site workers and standardizing the safety operating procedures of the power industry. As a supporting tool for testers, grounding wires are often used to provide grounding protection for electrical equipment to ensure the safety of workers during operations. Grounding wires and testers together constitute an important safety guarantee tool for substation operation and maintenance personnel in power outage operations, effectively preventing the risk of electric shock that may be caused during the operation of electrical equipment.

[0003] In the prior art, a Chinese patent with publication number CN212783863U discloses a grounding wire device that integrates electricity testing and hanging, which mainly includes a clamp, a contact type electroscope, an insulating rod and a traction mechanism. The working principle of the device is that the clamp and the electroscope are fixedly arranged on a bracket, and the clamp and the contact of the electroscope are connected by a wire; the top of the insulating rod is fixedly connected to the bracket; one end of the grounding wire is fixed on the traction mechanism, and the traction mechanism drives the grounding wire to climb along the insulating rod, and finally conducts with the clamp through the connector. This device solves the problem of installation and removal of the grounding wire to a certain extent, and improves the safety during the operation.

[0004] However, the grounding wire device in the prior art still has some shortcomings, which are specifically reflected in the following aspects: In the prior art, the bottom ends of the grounding wire and the insulating traction rope are not effectively constrained, and their bottom ends are in a free state. This means that during the operation, especially in a windy environment, the wind can easily cause the bottom ends of the grounding wire and the traction rope to swing. The swinging bottoms can easily interfere with surrounding objects, and even cause the grounding wire and the traction rope to become entangled, thereby affecting the smooth progress of the operation and bringing certain safety hazards. Specifically, when the grounding wire and the suspension rope swing and become entangled with each other under the action of wind, it not only reduces work efficiency, but may also cause equipment damage or personal injury.

[0005] The existing technology fails to effectively solve the interference problem between the ground wire and the suspension rope, especially when the wind is strong during the operation. Due to the lack of effective limiting structure at the bottom of the ground wire and the suspension rope, they are easily affected by the wind, resulting in mutual entanglement, causing unnecessary risks. In this case, the operator needs more time and energy to untangle the entangled ground wire and suspension rope, which increases the difficulty and danger of the operation.

[0006] Although the prior art provides a traction mechanism to adjust the height of the grounding wire, there are still deficiencies in the precise adjustment and stability of the grounding wire. Under the interference of wind, the bottom of the grounding wire may swing or shift position unnecessarily, which not only affects the working efficiency, but also may cause the grounding wire to fail to connect properly with electrical equipment or other facilities, thereby affecting safety. Summary of the invention

The bottom ends of the grounding wire and the suspension rope are effectively limited respectively, reducing mutual interference, ensuring that there will be no stagnation and safety hazards caused by winding during the operation. In use, the bottom end of the grounding wire passes downward through the first through hole of the anti-winding limiting unit of the base, and the first through hole can limit the bottom end of the grounding wire. At the same time, the bottom end of the suspension rope passes downward through the second through hole, and the second through hole can limit the bottom end of the suspension rope, that is, the bottom end of the grounding wire and the bottom end of the suspension rope are simultaneously limited by the first through hole and the second through hole respectively.

The first through hole and the second through hole are symmetrically distributed about the center of the base top plate, so that there is a certain distance between the first through hole and the second through hole, thereby ensuring that there is also a certain distance between the bottom end of the grounding wire and the bottom end of the suspension rope, further preventing the bottom end of the grounding wire and the bottom end of the suspension rope from being entangled with each other.

[0020] The present invention uses a slidable guide unit, so that the height and position of the grounding wire can be accurately adjusted and maintained in a vertical state, thereby ensuring the stability of the grounding wire during operation and avoiding position deviation of the grounding wire due to wind or environmental changes, thereby enhancing the accuracy and reliability of the operation.

[0021] The tensioning device of the present invention adjusts the tension of the grounding wire through a spring and a sliding shaft system, ensuring that the grounding wire always maintains sufficient tension, avoiding loose deformation or swinging of the grounding wire due to wind or other external factors, thereby enhancing the stability of the grounding wire and further ensuring operational safety.

DETAILED DESCRIPTION

[0032] The present invention is further described below in conjunction with the accompanying drawings.

[0033] like Figure 1-Figure 5 As shown, an automatic grounding wire assembly and disassembly device includes an insulating main rod 31, a top end of the insulating main rod 31 is equipped with an electric detection function unit, the electric detection function unit includes an electric detection rod 32, a top end of the electric detection rod 32 is fixed with a contact ring 33, and a top end of the contact ring 33 is fixed with a hook 34; The insulating main rod 31 is slidably sleeved with a slidable guide unit, which includes a guide cylinder 21, which is slidably sleeved on the insulating main rod 31, an insulating ring 22 is fixed on the top of the outer wall of the guide cylinder 21, a conductive ring 23 is fixed on the outer wall of the insulating ring 22, two conductive rods 24 are vertically fixed on the outer wall of the conductive ring 23, and the two conductive rods 24 are symmetrically distributed about the center line of the guide cylinder 21, a grounding wire 26 is installed on the conductive ring 23, and a movable annular plate 25 is fixed on the bottom end of the guide cylinder 21; a connecting rod 51 is fixed on one side of the guide sleeve 52, and the connecting rod 51 is fixed on one side of the movable annular plate 25, and the grounding wire 26 extends downward from the guide sleeve 52; A suspension rope 41 , one end of which is fixed on the movable annular plate 25 , and a fixed pulley 43 is mounted on the contact ring 33 , and the suspension rope 41 passes around the fixed pulley 43 .

[0034] During use, the staff hangs the hook 34 on the high-voltage line, and can detect whether the high-voltage line has electricity through the electric test rod 32. When it is detected that the high-voltage line is powered off, the bottom end of the hanging rope 41 is pulled downward, so that the hanging rope 41 slides downward along the fixed pulley 43, so that the other end of the hanging rope 41 drives the movable annular plate 25 to move upward, and the movable annular plate 25 drives the guide cylinder 21, the insulating ring 22, and the conductive ring 23 to move upward along the insulating main rod 31, and the conductive ring 23 drives the two conductive rods 24 to move upward, so that the top of the conductive rod 24 contacts the contact ring 33, so that the contact ring 33, the conductive rod 24, the conductive ring 23, and the grounding wire 26 are connected, thereby achieving the purpose of grounding.

[0035] When the guide cylinder 21 moves upward, the guide cylinder 21 drives the top of the grounding wire 26 to move upward through the conductive ring 23. At the same time, the movable annular plate 25 drives the guide sleeve 52 to move upward through the connecting rod 51, so that the guide sleeve 52 can always limit the top of the grounding wire 26. The connecting rod 51 and the guide sleeve 52 can support the top of the grounding wire 26 to the left, so that the top of the grounding wire 26 is away from the insulating main rod 31 and the hanging rope 41, so as to prevent the grounding wire 26 and the hanging rope 41 from being blown up by the wind and entangled, thereby ensuring smooth operation.

[0036] like Figure 1 , Figure 2 , Figure 6 , Figure 7 As shown, the base anti-winding limiting unit is fixed on the bottom end of the insulating main rod 31, and at least two through holes are opened on the base anti-winding limiting unit, which are used to guide the passage of the grounding wire and the suspension rope, respectively, and limit the bottom ends of the grounding wire 26 and the suspension rope 41, respectively, and the two through holes are symmetrically distributed about the center of the base top plate. The base anti-winding limiting unit includes: A base top plate 13, the base top plate 13 is fixed on the bottom end of the insulating main rod 31; A first through hole 27, which is formed on the top plate 13 of the base. The first through hole 27 is located directly below the guide sleeve 52, and the grounding wire 26 extends downward through the first through hole 27; The second through hole 44 is provided on the base top plate 13 . The first through hole 27 and the second through hole 44 are symmetrically distributed about the center of the base top plate 13 . The hanging rope 41 passes through the second through hole 44 and extends downward.

[0037] In use, the bottom end of the grounding wire 26 passes downward through the first through hole 27, and the first through hole 27 can limit the bottom end of the grounding wire 26. At the same time, the bottom end of the suspension rope 41 passes downward through the second through hole 44, and the second through hole 44 can limit the bottom end of the suspension rope 41, that is, the bottom end of the grounding wire 26 and the bottom end of the suspension rope 41 are simultaneously limited by the first through hole 27 and the second through hole 44. When the wind blows during the operation, the bottom end of the grounding wire 26 and the bottom end of the suspension rope 41 will not swing due to the wind, so as to avoid the bottom end of the grounding wire 26 and the bottom end of the suspension rope 41 being entangled with each other, thereby ensuring the smooth operation and eliminating safety hazards.

[0038] In addition, the design of the first through hole 27 being located directly below the guide sleeve 52 makes the grounding wire 26 located between the guide sleeve 52 and the first through hole 27 to be in a vertical downward state, so that the grounding wire 26 and the insulating main rod 31 are parallel to each other, avoiding the grounding wire 26 from being entangled on the insulating main rod 31 due to wind force, eliminating safety hazards. The design of the first through hole 27 and the second through hole 44 being symmetrically distributed about the center of the base top plate 13 makes a certain distance between the first through hole 27 and the second through hole 44, thereby ensuring that there is also a certain distance between the bottom end of the grounding wire 26 and the bottom end of the suspension rope 41, further avoiding the bottom end of the grounding wire 26 and the bottom end of the suspension rope 41 from being entangled with each other.

[0039] like Figure 1-Figure 3 As shown, the center line of the grounding wire 26, the center line of the suspension rope 41, and the center line of the insulating main pole 31 are located in the same vertical plane, and the grounding wire 26 and the suspension rope 41 are respectively located on both sides of the insulating main pole 31. There is a certain distance between the grounding wire 26 and the suspension rope 41 to prevent the two from being entangled with each other due to wind force.

[0040] like Figure 1 , Figure 2 As shown, a base frame 12 is fixedly arranged on the bottom surface of the seat top plate 13, a base bottom plate 11 is fixed to the bottom end of the base frame 12, and a winding mechanism is arranged on the base frame 12, and the winding mechanism includes: The winding motor 45 is mounted on the side wall of the base frame 12 . A winding roller 46 is fixed on the output shaft of the winding motor 45 . The bottom end of the suspension rope 41 is fixed on the winding roller 46 .

[0041] In use, when the winding motor 45 is started, the output shaft of the winding motor 45 drives the winding roller 46 to rotate, and the winding roller 46 winds up the bottom end of the suspension rope 41, so that the top end of the suspension rope 41 drives the guide cylinder 21 to move upward. Compared with the prior art, in this solution, the power source is arranged on the base frame 12, and there is no need to drive the winding motor 45 to move upward, thereby reducing the gravity that needs to be overcome when the guide cylinder 21 moves upward, which can save energy.

[0042] like Figure 4 As shown, an anti-rotation component is provided between the guide cylinder 21 and the insulating main rod 31, and the anti-rotation component includes: An anti-rotation groove 61, wherein the anti-rotation groove 61 is vertically formed on the inner wall of the guide cylinder 21; The anti-rotation rib 62 is fixed on the outer wall of the insulating main rod 31 along the vertical direction, and the anti-rotation rib 62 is located in the anti-rotation groove 61.

[0043] During use, the anti-rotation rib 62 and the anti-rotation groove 61 cooperate with each other to prevent the guide cylinder 21 from rotating around the axis of the insulating main rod 31, thereby preventing the top end of the grounding wire 26 and the top end of the suspension rope 41 from rotating around the insulating main rod 31 and becoming entangled with each other, thereby ensuring the smooth progress of the grounding operation.

[0044] like Figure 5 As shown, a mounting frame 42 is fixedly provided on one side of the contact ring 33 , and the fixed pulley 43 is arranged in the mounting frame 42 ; a distance sensor 8 is installed on the bottom surface of the mounting frame 42 .

[0045] In use, the contact ring 33 is mounted on the fixed pulley 43 through the mounting frame 42. The fixed pulley 43 can change the direction of the suspension rope 41 so that the winding roller 46 can wind up the bottom end of the suspension rope 41, so that the top end of the suspension rope 41 drives the movable annular plate 25 to move upward, thereby providing power for the top end of the grounding wire 26 to move upward. In addition, the distance sensor 8 is used to measure the distance from it to the movable annular plate 25. When the measured value reaches a predetermined value, it indicates that the two conductive rods 24 are in good contact with the contact ring 33. At this time, the winding motor 45 is turned off, so that the movable annular plate 25 stops moving upward, so that the conductive rod 24 and the contact ring 33 are in stable contact at this height.

[0046] like Figure 6 , Figure 7 As shown, the tensioning device adjusts the tension of the grounding wire 26 through a sliding shaft system and a spring. The tensioning device includes: Two tensioning side plates 70, both of which are fixed on the top surface of the base top plate 13, and the two tensioning side plates 70 are symmetrically distributed about the center line of the first through hole 27; A first tensioning roller 71, the first tensioning roller 71 is fixed between the top ends of the two tensioning side plates 70; Two transverse sliding grooves 72, the two transverse sliding grooves 72 are respectively provided on the two tensioning side plates 70, and a first sliding shaft 73 is slidably arranged between the two transverse sliding grooves 72; The second tensioning roller 74 is fixed on the first sliding shaft 73 , and the grounding wire 26 is located between the first tensioning roller 71 and the second tensioning roller 74 .

[0047] In use, when tension needs to be applied to the bottom end of the grounding wire 26, the first sliding shaft 73 is pushed to the left, so that the first sliding shaft 73 slides to the left in the horizontal sliding groove 72, and the first sliding shaft 73 drives the second tensioning roller 74 to move to the left, and then the first sliding shaft 73 is positioned in the left end of the horizontal sliding groove 72. Under the cooperation of the first tensioning roller 71 and the second tensioning roller 74, the bottom end of the grounding wire 26 is bent to form a broken line structure, thereby applying tension to the grounding wire 26, preventing the grounding wire 26 from swinging due to wind force, and further ensuring that the grounding wire 26 and the suspension rope 41 will not be entangled.

[0048] like Figure 6-Figure 9 As shown, it also includes: Two vertical slide grooves 75, the two vertical slide grooves 75 are respectively opened on the two tensioning side plates 70, and the top of the vertical slide groove 75 and the right end of the horizontal slide groove 72 are connected to each other; A second sliding shaft 76, the second sliding shaft 76 is slidably disposed between the two vertical sliding grooves 75; Two springs 77 are respectively arranged between two ends of the second sliding shaft 76 and two ends of the first sliding shaft 73 .

[0049] During use, when the second sliding shaft 76 is located at the bottom end of the vertical sliding groove 75, the grounding wire 26 extends vertically downward between the first tensioning roller 71, the second tensioning roller 74 and the first through hole 27. At this time, the two springs 77 are both in a vertical state, the second tensioning roller 74 is located at the lower right side of the first tensioning roller 71, and the bottom end of the grounding wire 26 extends vertically downward. This is the non-tensioned state of the bottom end of the grounding wire 26 to accommodate the upward movement of the top end of the guide cylinder 21 and the grounding wire 26.

[0050] When the second sliding shaft 76 is located at the right end of the horizontal sliding groove 72, the grounding wire 26 forms a zigzag structure between the first tensioning roller 71, the second tensioning roller 74, and the first through hole 27. Specifically, the two springs 77 are both in a horizontal state, and the second sliding shaft 76 supports the second tensioning roller 74 to the left through the spring 77, so that the second tensioning roller 74 is located below the left side of the first tensioning roller 71, and the second tensioning roller 74 opens the bottom end of the grounding wire 26 to the left, so that the bottom end of the grounding wire 26 forms a zigzag structure, thereby applying tension to the bottom end of the grounding wire 26 to prevent the bottom end of the grounding wire 26 from swinging due to wind force.

[0051] In addition, when the wind force suddenly increases, the bottom end of the grounding wire 26 will inevitably swing slightly. At this time, the bottom end of the grounding wire 26 pushes the second tensioning roller 74 to the right, and the second tensioning roller 74 moves to the right and compresses the spring 77, which has a buffering effect to adapt to the slight movement of the second tensioning roller 74, thereby adapting to the slight swing of the grounding wire 26, avoiding the grounding wire 26 from breaking due to the unadjustable tensioning force, and has the effect of protecting the grounding wire 26.

[0052] like Figure 6 , Figure 7 As shown, the two springs 77 are respectively located on the outside of the two tensioning side plates 70 to prevent the horizontal slide groove 72 and the vertical slide groove 75 from blocking the movement of the spring 77 during the adjustment process, ensuring that the second slide shaft 76 can be smoothly moved into the right end of the horizontal slide groove 72. The two ends of the first slide shaft 73 extend toward the outside of the two tensioning side plates 70 and form a handle. The staff applies force to the first slide shaft 73 by grasping the handle, so as to move the first slide shaft 73 into the left end of the horizontal slide groove 72.
