Description

Technical Field

[0001] The invention belongs to the technical field of power distribution working tools, in particular to a live lead disconnecting tool set. Background Art

[0002] With the increasing requirements of power users for power supply reliability and the need to optimize the business environment, the technology of non-stop operation of distribution network has been vigorously promoted in the daily operation and maintenance of distribution network. At present, when it comes to business expansion or fault elimination, the upper-level line cannot be shut down, and live operation must be carried out to disconnect and connect the flow line.

[0003] At present, insulated wire locking rods are often used for live connection and disconnection of drain wires. Conventional insulated wire locking rods basically only include insulating rods, bolts, wire locking hooks or slots, and transmission mechanisms. When performing operations, operators need to use the insulating rod to hang the wire locking hook on the wire to be fixed and tighten the bolts to lock it on the drain wire. Then, the drain wire is fixed by holding the insulating rod to prevent the lead wire from swinging. When using a traditional insulating locking rod to connect two leads, the operator on the pole is located below the live body on the pole tower, with a limited range of movement, and the arrangement direction of the lead wire to be connected is very random. Therefore, it is usually very difficult for the operator to choose a suitable workstation to disconnect the lead wire, which is very challenging in terms of work difficulty and physical exertion.

[0004] Since the cables will shake when suspended in the air, they need to be clamped and stabilized during the disconnection operation to facilitate the disconnection operation; at the same time, the above operation requires at least two people to perform, which is relatively labor-intensive. Summary of the invention

[0005] In order to solve the problem that one person cannot simultaneously complete the operations of locking and disconnecting the cable during the disconnection operation, the present invention provides a live lead disconnection tool kit.

[0006] The present invention is achieved through the following technical solutions:

[0007] A live wire disconnection tool kit includes a support rod made of insulating material, the top of the support rod is connected to a locking unit acting on a cable, the side wall of the upper part of the support rod is connected to a side support rod, and the side support rod is connected to a wire disconnection unit;

[0008] The wire breaking unit comprises a docking block three arranged at the top end of the side support rod, a docking block four is rotatably arranged on the docking block three, and a wire breaking shear is connected to the docking block four;

[0009] One handle of the wire cutter is installed on the docking block four, and the other handle is freely opened outside the docking block four, and the freely rotatable handles are linked by a pull line extending downward.

[0010] The cable is clamped and fixed by a locking unit to prevent shaking; the angle of docking block three relative to docking block four changes, which helps to break through the complex space limitations, and the cable is pulled by operating the wire cutter to disconnect the cable; the wire cutting operation can be completed by one person holding the tool, reducing labor costs.

[0011] A further improvement of the present invention is that the locking unit comprises a rotating drum rotatably arranged at the bottom of the support rod; the bottom end of the support rod is rotatably provided with a rotating drum;

[0012] The top of the support rod is provided with an angle adjustment component 1, which includes a docking block 1 installed at the top of the support rod, and the docking block 1 is connected to the docking block 2 through a rotating bracket 1; the adjacent end surfaces of the docking block 1 and the docking block 2 are both rotatably provided with meshing gears 1 that can cooperate with each other; the meshing gear 1 on the docking block 1 rotates synchronously with the rotating drum through a linkage member in the support rod;

[0013] The end surface of the docking block 2 away from the docking block 1 is connected with a clamping component 1 which cooperates with the meshing gear 1 on the docking block 2.

[0014] Docking block 1 and docking block 2 realize the angle change of the axis line on the rotating bracket 1, and the meshing angle of the two meshing gears 1 can change; by operating the rotating drum, the meshing gear 1 on the connecting docking block 1 rotates, and the cable can be hooked and tightened in cooperation with the clamping component 1, thereby achieving the stability of the cable by breaking through the spatial angle limitation.

[0015] A further improvement of the present invention is that the above-mentioned meshing gear 1 protrudes from the mounting surface. The mounting surface where the meshing gear 1 protrudes is provided enables the two meshing gears 1 to still form a meshing transmission state even after the angle changes.

[0016] A further improvement of the present invention is that the rotating bracket 1 is provided with a tightening member 1 for fixing the angle change. The angle of the rotating bracket 1 is fixed by the tightening member 1, so that the docking block 1 and the docking block 2 are stabilized after the angle change.

[0017] A further improvement of the present invention is that the above-mentioned docking block 1 is provided with a screw hole 1 that penetrates and is arranged obliquely, and the screw hole 1 is internally threaded with a limit screw that can abut against the docking block 2. The limit screw passes through the screw hole and abuts against the docking block 2, and by adjusting the position of the limit screw, the support after the angle of the auxiliary docking block 1 and the docking block 2 is achieved.

[0018] A further improvement of the present invention is that the side surface of the above-mentioned docking block 2 is provided with a plurality of screw holes 2 that can cooperate with the limiting screw rod along the axial direction. The screw holes 2 cooperate with the limiting screw rod to achieve the position limitation of the docking block 1 and the docking block 2 on the limiting screw rod, thereby achieving the fixing of the angle.

[0019] A further improvement of the present invention is that the clamping assembly 1 includes a wire locking hook, a threaded rod is connected between the wire locking hook and the docking block 2, one end of the threaded rod passes through the docking block 2 and is connected to the meshing gear 1 rotating on the docking block 2. Under the linkage action of the meshing gear 1, the threaded rod realizes that the wire locking hook and the cable are wound at a certain angle, thereby achieving a stable state for the cable.

[0020] A further improvement of the present invention is that the threaded rod is threadedly connected to and passes through the wire locking hook, and a clamping block is connected to the end of the threaded rod located in the wire locking hook. When the wire locking hook is hung on the cable, as the threaded rod rotates relative to the wire locking hook, the clamping block moves relative to the wire locking hook, so that the clamping block cooperates with the wire locking hook to clamp the cable stably.

[0021] A further improvement of the present invention is that an operating handle 1 is provided on the side wall of the drum for easy operation. The operation of lifting and driving the drum to rotate is convenient by the operating handle 1.

[0022] A further improvement of the present invention is that the weight of the scissor head of the above-mentioned wire cutting shears is greater than the weight of the handle, which is helpful in that in the initial state, the wire cutting shears are in an open state and the cutting operation is completed only by pulling the wire.

[0023] A further improvement of the present invention is that the opposing surfaces of the docking block 3 and the docking block 4 are both provided with meshing gears 2 that can cooperate with each other, and a tightening member 2 is provided through the docking block 3, the docking block 4 and the two meshing gears 2. Through the cooperation of the two meshing gears 2, the locking state after the angle change is improved.

[0024] A further improvement of the present invention is that the side support rod is in an overall L-shaped structure, which helps to improve the structural strength of the side support rod.

[0025] A further improvement of the present invention is that the above-mentioned docking block 4, the bending part of the side support rod and the connection part between the side support rod and the support rod are respectively provided with a guide pulley 1, a guide pulley 2 and a guide pulley 3 for guiding the wire, so as to constrain the wire and reduce the interference of the wire on the surrounding components.

[0026] A further improvement of the present invention is that the lower end of the support rod is provided with a detachable mounting seat, and the mounting seat is rotatably provided with an operating handle 2 for tightening the pull wire. The pull wire can be retracted and released by rotating the operating handle 2.

[0027] It can be seen from the above technical solutions that the beneficial effects of the present invention are: the cable is clamped and fixed by the locking unit to avoid shaking; the angle of docking block three changes relative to docking block four, which helps to break through the complex space limitations, and the wire pulling operation allows the wire cutter to disconnect the cable; the wire cutting operation can be completed by one person holding the tool, reducing labor costs.

[0036] As attached Figure 1-5As shown, a live wire disconnection tool kit includes a support rod 1 with a hollow interior and made of insulating material, the top of the support rod 1 is connected to a locking unit for acting on a cable, and the side wall of the upper part of the support rod 1 is connected to a side support rod 5, and the side support rod 5 is an L-shaped structure as a whole. This helps to improve the structural strength of the side support rod 5. The side support rod 5 is connected to a wire disconnection unit.

[0037] The wire breaking unit includes an angle adjustment component 2 6, which includes a docking block 3 601 arranged at the top of the side support rod 5, a docking block 4 602 is rotatably arranged on the docking block 3 601, and a wire breaking shear 7 is connected to the docking block 4 602; the opposite surfaces of the docking block 3 601 and the docking block 4 602 are both provided with meshing gears 2 that can cooperate with each other, and a tightening member 2 is provided through the docking block 3 601, the docking block 4 602 and the two meshing gears 2. Through the cooperation of the two meshing gears 2, the locking state after the angle change is improved.

[0038] The weight of the scissor head of the wire shears 7 is greater than the weight of the handle, which helps in that in the initial state, the wire shears 7 is in an open state, and the operation of shearing is completed only by pulling the wire.

[0039] One handle of the wire cutter 7 is installed on the docking block four 602, and the other handle is freely open on the outside of the docking block four 602, and the freely rotatable handles are linked by a pull wire extending downward.

[0040] The docking block 4 602, the bending part of the side support rod 5 and the connection part between the side support rod 5 and the support rod 1 are respectively provided with a guide wire wheel 1 604, a guide wire wheel 2 605 and a guide wire wheel 3 606 for guiding the wire. The wire is constrained to be routed, and the interference of the wire to the surrounding components is reduced.

[0041] The lower end of the support rod 1 is provided with a detachable mounting seat 8, and the mounting seat 8 is rotatably provided with an operating handle 2 801 that can tighten the pull line. The retraction and release of the pull line can be achieved by rotating the operating handle 2 801.

[0042] The bottom end of the support rod 1 is rotatably provided with a rotating drum 2; the side wall of the rotating drum 2 is provided with an operating handle 201 for easy operation. The operation of lifting and driving the rotating drum 2 to rotate by the operating handle 201 is convenient. The top of the support rod 1 is provided with an angle adjustment component 3, and the angle adjustment component 3 includes a docking block 301 installed on the top of the support rod 1, and the docking block 301 is connected to the docking block 2 302 through a rotating bracket 305; the rotating bracket 305 is provided with a tightening member 1 after the angle change is fixed. The angle of the rotating bracket 305 is fixed by the tightening member 1, so that the docking block 1 301 and the docking block 2 302 are stable after the angle change.

[0043] The adjacent end surfaces of the docking block 1 301 and the docking block 2 302 are both provided with meshing gears 1 304 that can cooperate with each other; the meshing gear 1 304 on the docking block 1 301 rotates synchronously with the rotating drum 2 through the linkage member in the support rod 1. The docking block 1 301 and the docking block 2 302 realize the angle change of the axis center line on the rotating bracket 1 305, and the two meshing gears 1 304 can change the meshing angle; by operating the rotating drum 2, the meshing gear 1 304 on the docking block 1 301 is connected to rotate, thereby achieving the breakthrough of the spatial angle limit and approaching the cable.

[0044] The meshing gear 1 304 protrudes from the mounting surface. The meshing gear 1 304 protrudes from the mounting surface so that the two meshing gears 1 304 can still form a meshing transmission state even after the angle changes.

[0045] The docking block 1 301 is provided with a screw hole 1 306 which penetrates and is arranged obliquely, and the screw hole 1 306 is internally threaded with a limiting screw 303 which can abut against the docking block 2 302. The limiting screw 303 passes through the screw hole 1 306 and abuts against the docking block 2 302. By adjusting the position of the limiting screw 303, the support after the angle of the auxiliary docking block 1 301 and the docking block 2 302 is realized.

[0046] The side of the second docking block 302 is axially provided with a plurality of second screw holes 307 that can cooperate with the limiting screw 303. The second screw holes 307 cooperate with the limiting screw 303 to achieve the position limitation of the docking block 1 301 and the second docking block 302 on the limiting screw 303, thereby achieving the fixing of the angle.

[0047] The end surface of the docking block 2 302 away from the docking block 1 301 is connected with a clamping component 1 4 that cooperates with the meshing gear 1 304 on the docking block 2 302 .

[0048] The clamping assembly 14 includes a wire locking hook 401, and a threaded rod 403 is connected between the wire locking hook 401 and the docking block 2 302, and one end of the threaded rod 403 passes through the docking block 2 302 and is connected to the meshing gear 1 304 rotating on the docking block 2 302. Under the linkage action of the meshing gear 1 304, the threaded rod 403 realizes that the wire locking hook 401 and the cable are wound at a certain angle to achieve a stable state for the cable. The threaded rod 403 is threadedly connected and passes through the wire locking hook 401, and the end of the threaded rod 403 located in the wire locking hook 401 is connected to a clamping block 402. When the wire locking hook 401 is hung on the cable, as the threaded rod 403 rotates relative to the wire locking hook 401, the linkage clamping block 402 moves relative to the wire locking hook 401, so that the clamping block 402 cooperates with the wire locking hook 401 to complete the clamping and stabilization of the cable.

[0049] The live lead disconnecting tool set described in the present invention clamps and fixes the cable through a locking unit to prevent shaking; the angle of the docking block three changes relative to the docking block four, which helps to break through the complex space limitations, and the wire pulling operation allows the wire cutter to disconnect the cable; the wire disconnecting operation can be completed by one person holding the tool, reducing labor costs.
