It can be directly connected or indirectly connected through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0039] The first embodiment of the present application provides a grounding wire hanging device. The structure and working principle of the grounding wire hanging device of this embodiment are described below using specific embodiments. It should be noted that the embodiments described below are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application. The grounding wire hanging device involved in the present application is introduced in detail below.

[0040] In modern power systems, high-voltage power grids are the main equipment for power transmission. High-voltage power grids are composed of multiple transmission lines formed by multiple transmission lines. When the lines are rebuilt, expanded, or damaged by external forces, the transmission lines need to be shut down for maintenance, and hanging the ground wire on the transmission lines is a necessary step for line maintenance.

[0041] When hanging the ground wire on the transmission line, the ground wire should be connected to the auxiliary tool and tied with an insulating rope. After the operator climbs onto the tower carrying the transmission line, he drags the auxiliary tool from the ground to the tower through the insulating rope, and holds the auxiliary tool to hang the ground wire on the transmission line that needs to be repaired.

[0042] In order to ensure that the ground wire can be hung on the transmission line, the existing auxiliary tools are usually equipped with a long hand-held rod, which makes the auxiliary tools too large and the operators cannot carry them with them when climbing the tower. They can only drag the auxiliary tools to the tower with an insulating rope after climbing the tower, which is troublesome and laborious. Therefore, how to reduce the size of the auxiliary tools has become a technical problem to be solved.

[0043] In order to solve the above problems, an embodiment of the present application provides a grounding wire hanging device, in which a first rod and a second rod can move telescopically relative to each other. When the operator operates, the first rod and the second rod are first contracted together to reduce the volume of the telescopic rod, so that the grounding wire hanging device can be carried with him. After climbing the pole tower, the first rod and the second rod are extended to lengthen the overall length of the telescopic rod, so as to ensure that the wire clamp can be clamped on the transmission line when the telescopic rod is held, thereby completing the hanging of the grounding wire. In addition, the telescopic rod and the wire clamp are detachably connected. When the wire clamp is clamped on the transmission line, the operator can separate the telescopic rod and the wire clamp through a disassembly action, thereby disassembling the telescopic rod to prevent the telescopic rod from being affected by natural erosion and affecting the insulation performance. At the same time, the retractor can retract and release the insulating pull rope connected to the wire clamp. The operator only needs to operate on the telescopic rod to control the opening and closing of the wire clamp, making the process of hanging the grounding wire more convenient.

[0044] The ground wire hanging device provided in the embodiment of the present application is specifically as follows: Figure 1 and Figure 2 As shown, Figure 1 A schematic diagram of the structure of the telescopic rod of the ground wire hanging device provided in this embodiment in an extended state, Figure 2 A schematic structural diagram of the telescopic rod of the ground wire hanging device provided in this embodiment in a retracted state.

[0045] The grounding wire hanging device comprises: a wire clamp 10 and a telescopic rod 20; the wire clamp 10 is connected to the grounding wire 30, and a first docking piece 11 is arranged on the wire clamp 10; the telescopic rod 20 comprises a first rod 21 and a second rod 22, and a second docking piece 23 matching the first docking piece 11 is arranged at a first end of the first rod 21; the second rod 22 can perform telescopic movement based on the second end of the first rod 21 to adjust the distance between the second docking piece 23 and the second rod 22; the second docking piece 23 docks with the first docking piece 11 along the disassembly and assembly direction of the second docking piece 23 to form a detachable connection, and the second docking piece 23 can be separated from the first docking piece 11 along the disassembly and assembly direction of the second docking piece 23; an insulating pull rope 17 is also connected to the wire clamp 10, and a retractor 25 is installed on the telescopic rod 20, and the insulating pull rope 17 is retracted in the retractor 25; the retractor 25 retracts and releases the insulating pull rope 17 by winding the handle to control the opening and closing of the wire clamp 10. The retractor 25 can be detachable, for example, a card slot is provided on the telescopic rod, and a card platform is provided on the retractor 25 to facilitate subsequent disassembly.

[0046] In this embodiment, the wire clamp 10 is made of conductive material and connected to the ground wire 30. The wire clamp 10 is used to clamp on the transmission line to connect the ground wire 30 to the transmission line, so that the current of the transmission line is introduced into the ground through the ground wire 30 when the transmission line is detected.

[0047] The telescopic rod 20 is made of insulating material and is used for the operator to hold. The first rod 21 and the second rod 22 of the telescopic rod 20 can perform telescopic movement relative to each other, so that the operator can adjust the overall length of the telescopic rod 20 by adjusting the telescopic state of the first rod 21 and the second rod 22 of the telescopic rod 20, so that the operator can carry it with him or the length of the telescopic rod 20 can be adjusted to the clamping position of the wire clamp 10 on the power transmission line.

[0048] The first end of the first rod 21 is provided with a second docking member 23 matched with the first docking member 11, and the second end of the first rod 21 is close to the first end of the second rod 22. In addition, when the second rod 22 is telescoped relative to the first rod 21, the telescopic movement is based on the second end of the first rod 21, and the distance between the second docking member 23 and the second rod 22 is adjusted accordingly.

[0049] Specifically, when the second rod 22 performs an extension movement based on the second end of the first rod 21, the second rod 22 extends outward from the second end of the first rod 21, and the second end of the second rod 22 continuously moves away from the first end of the first rod 21, thereby lengthening the overall length of the telescopic rod 20 and increasing the distance between the second docking piece 23 and the second end of the second rod 22. When the second rod 22 performs a retracting movement based on the second end of the first rod 21, the second rod 22 shrinks from the second end of the first rod 21 to the first end of the first rod 21, thereby continuously approaching the second end of the second rod 22 to the first end of the first rod 21, thereby shortening the overall length of the telescopic rod 20 and decreasing the distance between the second docking piece 23 and the second end of the second rod 22, so as to reduce the volume of the grounding wire hanging device.

[0050] The first docking member 11 and the second docking member 23 are mutually matched connection structures, and the first docking member 11 and the second docking member 23 can be docked simply and quickly, so that the telescopic rod 20 and the wire clamp 10 form a detachable connection. In specific operation, the operator mainly holds the telescopic rod 20 to perform the disassembly action, so as to dock the second docking member 23 with the first docking member 11 along the disassembly direction of the second docking member 23.

[0051] In this embodiment, the wire clamp 10 is a clamping structure that can be opened and closed. The wire clamp 10 is clamped on the power transmission line, which means that the wire clamp 10 is fixed on the power transmission line by a clamping force.

[0052] A specific implementation method can be as follows Figure 3 As shown, Figure 3A schematic diagram of the structure of a wire clamp provided in this embodiment. The wire clamp 10 includes a first clamping member 12, a second clamping member 13, a first elastic member 14, and a rotating shaft 15. The first clamping member 12 and the second clamping member 13 are hinged to form a clamping angle through the rotating shaft 15. The first elastic member 14 is arranged between the first clamping member 12 and the second clamping member 13 to provide a clamping elastic force for the first clamping member 12 and the second clamping member 13, so that the clamping angle is closed under the elastic force of the clamping elastic force.

[0053] Furthermore, a wire groove 16 may be provided on the first clamping member 12 and / or the second clamping member 13, and the size of the wire groove 16 matches the size of the power transmission line on which the grounding wire 30 is hung. In a specific embodiment, when the wire groove 16 is provided on both the first clamping member 12 and the second clamping member 13, the wire groove 16 on the first clamping member 12 and the wire groove 16 on the second clamping member 13 may be combined into a channel for accommodating the power transmission line, so that the wire clamp 10 is hung on the power transmission line when the clamping angle is closed, so that the grounding wire is hung on the power transmission line. When the wire groove 16 is provided on the first clamping member 12 or the second clamping member 13, that is, when the wire groove 16 is provided on only one of the first clamping member 12 and the second clamping member 13, the clamping member without the wire groove 16 will block the opening of the wire groove 16 when the clamping angle is closed, so that the wire groove 16 forms a channel for accommodating the power transmission line, so that the wire clamp 10 is hung on the power transmission line, so that the grounding wire is hung on the power transmission line.

[0054] In this embodiment, in order to more conveniently control the opening and closing of the clamping angle of the wire clamp 10, an insulating pull rope 17 is provided on the wire clamp 10, and the insulating pull rope 17 is reeled in the reel 25, so that the insulating pull rope 17 is pulled by the reel 25, so that the wire clamp 10 is affected by the working action of the telescopic rod 20 and the insulating pull rope 17, so that the opening and closing of the wire clamp 10 changes with the action of the reel 25 to retract and release the insulating pull rope 17.

[0055] Specifically, a first docking member 11 may be provided on one clamping member, and an insulating pull rope 17 may be provided on another clamping member, so that the telescopic rod 20 and the insulating pull rope 17 can simultaneously apply force to the first clamping member 12 and the second clamping member 13 to control the opening and closing of the clamping angle of the wire clamp 10 .

[0056] For example, a feasible implementation method can be as follows Figure 3 As shown, the second docking member 23 is arranged on the first clamping member 12, and the force-applying end of the second clamping member 13 is provided with an insulating pull rope 17. Alternatively, the second docking member 23 can be arranged on the second clamping member 13, and the force-applying end of the first clamping member 12 is provided with an insulating pull rope 17.

[0057] According to different reeling principles, the reel 25 can be set to different structural forms. For example, it can be set to a reeling structure that retracts and releases the insulating pull rope 17 under the action of a coil spring, or it can be set to a reeling structure that is directly retracted manually by an operator, and no specific restrictions are made here. The operating member of the reel 25 can be set to a button, a wheel, a crank, etc., and the specific setting can be made correspondingly according to the reeling principle of the reel 25, and no restrictions are made here. The reel is also equipped with a handle for rotating the reel.

[0058] In addition, the installation posture of the first docking member 11 on the wire clamp 10 will affect the disassembly direction of the second docking member 23, thereby affecting the angle between the axis of the telescopic rod 20 and the clamping direction of the wire clamp 10, and then the operator's action of applying force by holding the telescopic rod 20.

[0059] In a feasible implementation, the first docking member 11 can be fixed on the wire clamp 10, and the axis of the telescopic rod 20 and the clamping direction of the wire clamp 10 are at a preset angle, so that the operator can apply force by holding the telescopic rod 20 more smoothly.

[0060] In another feasible embodiment, the first docking member 11 can be rotatably connected to the wire clamp 10, for example, by an adjustable universal damping, such as a spherical damping pan / tilt, so that the angle between the axis of the telescopic rod 20 and the clamping direction of the wire clamp 10 can be adjusted by the rotation of the first docking member 11, so that the operator can adjust the installation posture of the first docking member 11 on the wire clamp 10 and make the wire clamp 10 perform universal rotation; thereby adjusting the angle between the axis of the telescopic rod 20 and the clamping direction of the wire clamp 10 to an angle that is convenient for applying force. In addition, in a further embodiment, a limiter can also be provided on the wire clamp 10 to limit the rotation angle of the first docking member 11 relative to the wire clamp 10, thereby controlling the angle between the axis of the telescopic rod 20 and the clamping direction of the wire clamp 10.

[0061] In this embodiment, the first docking member 11 and the second docking member 23 can move telescopically relative to each other. The assembly and disassembly direction of the second docking member 23 refers to the moving direction of the second docking member 23 relative to the first docking member 11 when the second docking member 23 is docked or disassembled with the first docking member 11. For example, if the second docking member 23 is an axis and the first docking member 11 is a hole matching the axis, the assembly and disassembly direction of the axis is the axial direction of the hole. If the second docking member 23 is a plug-in and the first docking member 11 is a slot, the assembly and disassembly direction of the second docking member 23 is the plug-in direction for plugging with the first docking member 11.

[0062] There are many ways to set the second docking member 23 and the first docking member 11. For example, the second docking member 23 and the first docking member 11 can be set as a threaded connection structure, or a plug-in structure, or other feasible structures, which are not limited here.

[0063] When the second docking member 23 and the first docking member 11 are configured as a threaded connection structure, in a feasible implementation, the first docking member 11 includes a threaded hole, and the second docking member 23 includes a threaded rod matched with the threaded hole; the threaded rod is threadedly connected to the threaded hole along the axial direction of the threaded hole to form a detachable connection, and the threaded rod can be screwed out of the threaded hole along the axial direction of the threaded hole by a rotation action to be separated from the threaded hole. In a more specific implementation, the axis of the threaded rod is colinear with the axis of the first rod 21, and when the operator operates, the telescopic rod 20 can be held by the operator to rotate, thereby driving the threaded rod to be screwed into or out of the threaded hole, so that the threaded rod is inserted into the threaded hole or separated from the threaded hole along the axial direction of the threaded hole.

[0064] When the second docking member 23 and the first docking member 11 are configured as a threaded connection structure, another feasible implementation may be that the first docking member 11 includes a threaded rod, and the second docking member 23 includes a threaded hole matching the threaded rod; the threaded hole is threadedly connected to the threaded rod along the axial direction of the threaded rod to form a detachable connection, and the threaded hole can be separated from the threaded rod by rotating the threaded rod along the axial direction of the threaded rod. In a more specific implementation, the axis of the threaded hole is colinear with the axis of the first rod 21, and the operator can hold the telescopic rod 20 and rotate it, thereby driving the threaded hole to be screwed in or out of the threaded hole, so that the threaded hole is inserted into the threaded rod or separated from the threaded rod along the axial direction of the threaded rod.

[0065] When the second docking member 23 and the first docking member 11 are configured as a plug-in structure, a feasible implementation method may be that the second docking member 23 is configured as a prism, and the first docking member 11 is configured as a prism hole matching the prism; the prism is fixed to the first end of the first rod 21, and the angle between the axis of the prism and the axis of the first rod 21 is an obtuse angle; the prism can be inserted into the prism hole or pulled out from the prism hole along the axis direction of the prism hole. When operating, the operator can hold the telescopic rod 20 to insert the prism into the prism hole or pull it out from the prism hole along the axis direction of the prism hole.

[0066] Furthermore, in order to facilitate the assembly and disassembly of the first docking member 11 and the second docking member 23, the first docking member 11 and the second docking member 23 can be configured as Figure 4 The structure shown, Figure 4 A schematic diagram of the structure of a first docking piece and a second docking piece docking with each other provided in this embodiment.

[0067] Specifically, Figure 4As shown, the first docking member 11 is provided with a slot 18, and the second docking member 23 is provided with a stopper 40, such as a pin, which matches the slot 18. At the same time, the second docking member 23 is provided with a second elastic member 50. When the first docking member 11 and the second docking member 23 are connected, the second elastic member 50 is in a compressed state, and the two ends of the second elastic member 50 are respectively against the first docking member 11 and the second docking member 23, so that the stopper 40 is stuck in the slot 18 under the elastic force of the second elastic member 50. When the operator wants to remove the second docking member 23 from the first docking member 11, he only needs to hold the telescopic rod 20 to apply force to control the stopper 40 on the second docking member 23 to move in the direction of leaving the slot 18. When the locking member 40 is separated from the locking slot 18, the second elastic member 50 stretches, and the elastic force of the second elastic member 50 acts on the first docking member 11 and the second docking member 23 to push the second docking member 23 away from the first docking member 11, thereby making the disassembly process of the second docking member 23 more labor-saving.

[0068] When the second docking member 23 and the first docking member 11 are configured as a plug-in structure, another feasible implementation method may be that the second docking member 23 is configured as a prism hole, and the first docking member 11 is configured as a prism matching the prism hole; the prism hole is fixed to the first end of the first rod 21, and the angle between the axis of the prism hole and the axis of the first rod 21 is an obtuse angle; the prism hole can be inserted into the prism hole along the axis direction of the prism, and the prism hole can be pulled out of the prism hole along the axis direction of the prism. When the operator operates, he can hold the telescopic rod 20 to insert the prism into the prism or separate it from the prism along the axis direction of the prism.

[0069] In addition, there are many ways to configure the specific structure of the relative extension of the first rod 21 and the second rod 22.

[0070] A possible implementation method can be as follows Figure 5 and Figure 6 As shown, Figure 5 A schematic diagram of the structure of a first rod provided in this embodiment, Figure 6 The schematic diagram of the structure of the second rod provided in this embodiment is as follows. The second rod 22 is provided with a cavity 24 for accommodating the first rod 21, and the first rod 21 can perform telescopic movement in the cavity 24 of the second rod 22; or the first rod 21 is provided with a cavity 24 for accommodating the second rod 22, and the second rod 22 can perform telescopic movement in the cavity 24 of the first rod 21.

[0071] In another feasible implementation, a slide groove is provided on the first rod 21, and a slider matching the slide groove on the first rod 21 is fixed on the second rod 22; or a slide groove is provided on the second rod 22, and a slider matching the slide groove on the second rod 22 is fixed on the first rod 21. The slider is stuck in the slide groove and can slide in the slide groove, so that the second rod 22 can perform telescopic movement relative to the first rod 21 through the sliding of the slider in the slide groove.

[0072] In addition, a stopper, a thread or other structures may be further provided to relatively fix the first rod 21 and the second rod 22 when the second rod 22 is extended to a preset length of the entire length of the second rod 22 and the first rod 21 .

[0073] In the grounding wire hanging device provided above, the first rod and the second rod can move telescopically relative to each other. When the operator operates, he first contracts the first rod and the second rod together to reduce the volume of the telescopic rod, so that the grounding wire hanging device can be carried with him. After climbing the pole tower, the first rod and the second rod are stretched out to lengthen the overall length of the telescopic rod, so as to ensure that the wire clamp can be clamped on the transmission line when the telescopic rod is held, thereby completing the hanging of the grounding wire. In addition, the telescopic rod and the wire clamp are detachably connected. When the wire clamp is clamped on the transmission line, the operator can separate the telescopic rod and the wire clamp through a disassembly action, thereby disassembling the telescopic rod to prevent the telescopic rod from being affected by natural erosion and affecting the insulation performance. At the same time, the retractor can retract and release the insulating pull rope connected to the wire clamp. The operator only needs to operate on the telescopic rod to control the opening and closing of the wire clamp, making the process of hanging the grounding wire more convenient.

[0074] It should be noted that, although several structures, components or units for realizing related functions are mentioned in the above detailed description, such division is not mandatory. In fact, according to the specific implementation of the present application, the features and functions of two or more structures, components or units described above can be concretized in one structure, component or unit.
