Description

Technical Field

[0001] The invention relates to a construction device for high-voltage live-line operation in an electric power system, in particular to a live-line splicing auxiliary device. Background Art

[0002] At present, workers are faced with the following problems when performing live work on 10KV lines: 1. When connecting the unloaded line to the energized main line according to the wire diameter and length of the unloaded line, the live wire will be touched, and there will be capacitive current shock, which may cause certain harm to the human body. At present, workers who perform live work completely rely on the insulating properties of "insulating gloves" to prevent harm from capacitive current, which is very risky; 2. During live work, for single-circuit shielded wires and complex double-circuit wires, since the vehicle cannot stop at the designated position, there is a situation where the wires cannot be effectively merged, and it is easy to touch objects with different potentials in the merged wires, which poses a safety hazard; 3. For complex lines, due to the merged wires, the procedure for insulation shielding operation is more cumbersome, and if it is protected with an insulating operating rod, it will take longer and increase the physical burden on the workers. Summary of the invention

[0003] Purpose of the invention: In view of the above problems, the purpose of the present invention is to provide a live splicing auxiliary device to effectively bring together unloaded lines at a designated working position, solve the safety hazard problem of objects with different electrical potentials touching each other in the convergence line, and improve efficiency.

[0004] Technical solution: A live splicing auxiliary device, comprising a base, a live wire clamp, a rotating connector, a splicing wire locking assembly, and an insulating operating rod. The base has an L-shaped cross-section, the live wire clamp is connected to the vertical outer side surface of the base through the rotating connector, the splicing wire locking assembly is installed on the lateral inner side surface of the base, and the insulating operating rod is threadedly connected to the bottom surface of the base.

[0005] Furthermore, the live wire clamp includes a clamp body and a clamping strip, wherein the clamping strip is transversely passed through the clamping portion of the clamp body, one end of which is hinged to one of the clamping claws of the clamp body, and a vertical long groove is provided on the other clamping claw of the clamp body, and the other end of the clamping strip is passed through the long groove.

[0006] Furthermore, a notch is provided on one end of the clamping strip connected to the long slot and is opened along the extending direction of the clamping strip.

[0007] Furthermore, the overlapping wire locking assembly includes a wire trough seat, a limit screw, a limit card, and a locking nut. The wire trough seat is fixed on the lateral inner side of the base, and a wire locking groove is vertically opened on one side surface of the wire trough seat. The limit screw enters from one side of the wire trough seat and exits from the other side. The limit card is fixed to one end of the limit screw and is opposite to the wire locking groove. The limit card spans the wire locking groove, and the locking nut is threadedly connected to the outer peripheral surface of the other end of the limit screw.

[0008] The overlapping wire locking assembly is used to fix the unloaded wires to be overlapped. The unloaded wires are placed in the wire locking groove, the locking nut is loosened and the limiting screw is pulled to make the limiting card press the unloaded wire, and then the locking nut is re-tightened, so that the unloaded wire is limited between the wire locking groove and the limiting card.

[0009] Preferably, a rotating handle is provided on the outer peripheral surface of the locking nut.

[0010] Furthermore, the rotating connecting part includes a rotating gear 1, a rotating gear 2, a connecting rod, a rotating sleeve, and a fastening nut. The rotating gear 1 is fixed to the vertical outer side surface of the base, and the rotating gear 2 is fixed to an outer side surface of the pressing portion of the live wire clamp.

[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0018] A live bonding auxiliary device, such as Figures 1 to 5 As shown, it includes a base 1, a live wire clamp 2, a rotating connector 3, a lapped wire locking assembly 4, and an insulating operating rod 5, and the base 1 is made of aluminum plate.

[0019] The cross-section of the base 1 is L-shaped, and the lapped wire locking assembly 4 is installed on the lateral inner side surface of the base 1. The lapped wire locking assembly 4 includes a wire slot seat 41, a limit screw 42, a limit card 43, and a locking nut 44. The wire slot seat 41 is fixed on the lateral inner side surface of the base 1, and a wire locking slot 411 is vertically opened on one side surface of the wire slot seat 41. The limit screw 42 penetrates from one side surface of the wire slot seat 41 and exits from the other side. The limit card 43 is fixed to one end of the limit screw 42 and is opposite to the wire locking slot 411. The surface opposite to the wire locking slot 411 is a concave arc surface. The limit card 43 spans the wire locking slot 411. The locking nut 44 is threadedly connected to the outer peripheral surface of the other end of the limit screw 42, and a rotating handle is provided on the outer peripheral surface of the locking nut 44 to facilitate the rotation of the locking nut 44. The overlapping wire locking assembly 4 is used to fix the unloaded wires to be overlapped. The unloaded wires are placed in the locking wire groove 411. After loosening the locking nut 44, the limiting screw 42 is pulled to make the limiting card 43 press the unloaded wire. Then, the locking nut 44 is re-tightened, so that the unloaded wire is limited between the locking wire groove 411 and the limiting card 43.

[0020] The live wire clamp 2 is connected to the vertical outer side surface of the base 1 through a rotating connector 3. The live wire clamp 2 includes a clamp body 21 and a clamping strip 22. The clamping strip 22 is horizontally inserted into the clamping portion of the clamp body 21, and one end of the clamping strip 22 is hinged to one of the clamping claws of the clamp body 21. A vertical long groove is provided on the other clamping claw of the clamp body 21. The other end of the clamping strip 22 is inserted into the long groove. A notch 221 is provided along the extension direction of the clamping strip 22 on the end of the clamping strip 22 connected to the long groove. The live wire clamp 2 is used to clamp the live high-voltage wire, and the live high-voltage wire is clamped in the clamping part of the clamp body 21. In order to prevent the live high-voltage wire from falling off from the clamping mouth of the clamp body 21, the live high-voltage wire is limited by the clamping strip 22. The live high-voltage wire is limited in the triangular area formed by the clamping part of the clamp body 21 and the clamping strip 22. At this time, the clamping strip 22 rotates around the hinge point so that its other end moves in the long groove of the clamping claw, and the step of the notch 221 abuts against the end of the long groove. Under the clamping force of the clamp body 21 itself, the clamping strip 22 is positioned, thereby ensuring that the live high-voltage wire cannot fall off from the clamping mouth of the clamp body 21.

[0021] The rotating connector 3 includes a rotating gear 1 31, a rotating gear 2 32, a connecting rod 33, a rotating sleeve 34, and a fastening nut 35. The rotating gear 1 31 is fixed to the vertical outer side of the base 1, and the rotating gear 2 32 is fixed to an outer side of the pressing portion of the clip body 21. One end of the connecting rod 33 is laterally inserted from the other outer side of the pressing portion of the live wire clamp 2 to pass through the rotating gear 2 32 and is fixed to the middle of the rotating gear 1 31. The rotating sleeve 34 is sleeved on the connecting rod 33, and one end of the rotating sleeve is fixed to the pressing portion of the clip body 21. The clamping claw 31 is fixed to the inner side of the clamping claw with the rotating gear 2 32, the fastening nut 35 is threadedly connected to the other end of the connecting rod 33 and abuts against the other end of the rotating sleeve 34, so that the rotating gear 1 31 is meshed with the rotating gear 2 32, and a U-shaped opening is provided on the clamping claw without the rotating gear 2 32 in the pressing part of the clamp body 21, so that the connecting rod 33, the rotating sleeve 34, and the fastening nut 35 do not interfere with the clamping claw, thereby ensuring that the clamping claw can be pressed freely and the normal use of the live wire clamp 2 is ensured. The rotating connector 3 allows the orientation of the clamping opening of the live wire clamp 2 to be 360° adjustable relative to the base 1, so that it is more convenient for the live wire clamp 2 to clamp the high-voltage live wire. When the position of the live wire clamp 2 needs to be adjusted, first loosen the fastening nut 35. At this time, the meshing relationship between the rotating gear 1 31 and the rotating gear 2 32 can be manually released. The live wire clamp 2 can be rotated on the connecting rod 33 by rotating the sleeve 34. At this time, the rotating gear 2 32 rotates together. When the live wire clamp 2 is rotated to the desired position, re-tighten the fastening nut 35. By rotating the sleeve 34, the tightening force is transmitted to the live wire clamp 2 and the rotating gear 2 32 in turn, so that the rotating gear 1 31 and the rotating gear 2 32 are meshed and tightened again, and the position of the live wire clamp 2 relative to the base 1 is fixed again.

[0022] The insulating operating rod 5 is threadedly connected to the bottom surface of the base 1 , and the length of the insulating operating rod 5 can be selected according to the distance of the operation point.

[0023] When using this device, firstly, the spliced ​​unloaded wires are firmly fixed by the spliced ​​wire locking assembly, and then the direction of the live wire clamp is adjusted and selected by rotating the connecting piece according to the position of the electrician at that time, and then the high-voltage live wire is clamped by the live wire clamp.

[0024] For complex multi-circuit operations, the operating electrician can fix the live wire clamp of this device on the main line, rotate the connection position of the insulating operating rod and the base to separate them. At this time, the spliced ​​unloaded line has been transferred to the required operation point and is at the same potential as the energized main line, avoiding the harm of the spliced ​​capacitive current to the human body. Then adjust the position of the live working vehicle to the working position that is most conducive to splicing, and perform the live splicing work. After the branch line is completely and firmly spliced ​​with the energized main line, adjust the splicing wire locking assembly to separate the branch line (the original unloaded wire) from the device. For simple triangular arrangement lines, to cross the shielding line, the live wire clamp does not need to be adjusted multiple times. Turn the clamp downward, and perform the transfer of phase conductors with different potentials at a reasonable and safe position below the line, strip the wires and splice. After the work is completed, remove the device below the energized line.

[0025] Through the cooperation of the live wire clamp and the overlapping wire locking assembly, this device can effectively gather the unloaded lines at the designated working position, solve the hidden danger of touching objects with different potentials in the merged lines, and through the overlapping wire locking assembly, the unloaded lines after the merged lines are already at the same potential as the main line before the splicing, and the operating electrician is far away from the splicing point, with a sufficient safety distance, which can effectively solve the accidental injury of capacitive current during live splicing, greatly shorten the operation procedures, reduce the physical strength of the operators, and achieve quality improvement and efficiency increase.
