Description

Technical Field

[0001] The invention belongs to the technical field of power distribution working tools, in particular to a variable-angle insulating locking rod used for live working. 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 lead 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 lead wire. Then, the lead 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 lead wires, 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 and connect the lead wire, which is very challenging in terms of work difficulty and physical exertion. Summary of the invention

[0004] In order to solve the problem that during the operation of cutting and connecting the lead wires, the cables are swaying due to distance and space limitations, which increases the difficulty of stable construction for operators, the present invention provides a variable-angle insulating locking rod for live working.

[0005] The present invention is achieved through the following technical solutions:

[0006] A variable-angle insulating locking rod for live working, comprising a supporting rod made of insulating material, wherein a rotating drum is rotatably provided at the bottom end of the supporting rod;

[0007] 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;

[0008] 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.

[0009] 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.

[0010] 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.

[0011] 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.

[0012] 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.

[0013] 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.

[0014] 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.

[0015] 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.

[0016] 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.

[0017] It can be seen from the above technical scheme that the beneficial effects of the present invention are: the docking block 1 and the docking block 2 realize the angle change of the axis line on the rotating bracket 1, and the two meshing gears 1 can change the meshing angle; by operating the rotating drum, the meshing gear 1 on the connecting docking block 1 rotates, and the clamping component 1 is cooperated to hook the cable, thereby breaking through the spatial angle limitation to stabilize the cable.

DETAILED DESCRIPTION

[0023] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solution of the present invention will be clearly and completely described below in conjunction with the drawings in this specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0024] As attached Figure 1-3As shown, a variable angle insulating locking rod for live working includes a support rod 1 with a hollow interior and made of insulating material, a rotating drum 2 being rotatably provided at the bottom end of the support rod 1; an operating handle 201 for easy operation is provided on the side wall of the rotating drum 2. The operation of lifting and driving the rotating drum 2 to rotate by the operating handle 201 is convenient. An angle adjustment component 3 is provided at the top of the support rod 1, and the angle adjustment component 3 includes a docking block 301 installed at the top of the support rod 1, and the docking block 301 is connected to a docking block 2 302 through a rotating bracket 305; a tightening piece 1 after fixing the angle change is provided on the rotating bracket 305. The angle of the rotating bracket 305 is fixed by the tightening piece 1, so that the docking block 1 301 and the docking block 2 302 are stable after the angle change.

[0025] 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.

[0026] 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.

[0027] 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.

[0028] 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.

[0029] 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 .

[0030] 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.

[0031] The invention discloses a variable-angle insulating locking rod for live working, in which a docking block 1 and a docking block 2 realize angle changes of the axis lines on a rotating bracket 1, and two meshing gears 1 can change their meshing angles; by operating a rotating drum, the meshing gear 1 on the connecting docking block 1 rotates, and in cooperation with a clamping assembly 1, the cable can be hooked and tightened, thereby achieving cable stability without being limited by spatial angles.
