Description

Technical Field

[0001] This utility model relates to the field of power engineering technology, and in particular to an insulating support rod locking device for live poles. Background Technology

[0002] With the development of the power industry and the continuous expansion of the power grid, live-line work plays an increasingly important role in power system maintenance, emergency repair, and upgrades. Live-line work, which involves inspecting or constructing electrical equipment without interrupting power, greatly improves power supply reliability and grid operation efficiency. Researchers have conducted in-depth research on the high-risk operation of erecting and removing live poles, aiming to ensure that workers can complete the task efficiently and safely. A key step in this process is to separate the conductors on both sides of the work area to maintain a sufficient phase-to-phase safety distance. This prevents short circuits or discharge accidents caused by insufficient conductor spacing, ensuring the safety of workers and the stable operation of the power grid. The phase-to-phase safety distance refers to the minimum distance that should be maintained between two adjacent conductors and is a core component of live-line work safety regulations.

[0003] Existing live pole erection and removal technology includes specialized tools and equipment capable of safely separating two electrical wires. These tools, typically made of insulating materials, can operate in live environments without causing short circuits, while simultaneously connecting the live pole to a guide to reliably separate and reconnect the wires. These advancements not only improve operational efficiency but also significantly reduce operational risks, making live pole erection and removal possible.

[0004] However, despite the significant achievements of existing technologies in separating wires, some shortcomings remain in practical operation. In particular, the connection between the support rod and the fixing locking device currently relies heavily on rubber rings and clamps. While this connection method is simple and easy to implement, under long-term inward tension from the wires, if the fixing clamps are not tightened sufficiently or gradually loosen over time, it can easily lead to instability in the locking device, thereby threatening the safety of the entire operation. Utility Model Content

[0005] To overcome the drawback of the risk of loosening, this utility model provides a stable insulating support rod locking device for live poles.

[0006] An insulating support rod locking device for a live pole includes an insulating support rod with multiple limiting holes. A locking rod is slidably connected to each limiting hole of the insulating support rod. A nut is threaded to the bottom of the locking rod. A ring is rotatably connected to the top of the locking rod. A rotating seat is connected to the ring. A clamp is rotatably connected to the rotating seat. The clamp is connected to a wire. A locking component for restricting the rotation of the clamp is provided inside the rotating seat.

[0007] Optionally, the locking assembly includes a connecting rod, the bottom of the clamp is connected to the connecting rod, the connecting rod is rotatably connected to the rotating seat, one side of the connecting rod is connected to a rubber pad, the side of the rotating seat is rotatably connected to a connecting ring, the connecting ring is connected to an operating plate, the operating plate is press-fitted with the connecting rod and the rubber pad, the connecting rod is provided with a notch, and the operating plate is provided with a flexible pad.

[0008] Optionally, the insulating support rod is connected to a plurality of identification cards, the identification cards corresponding to the limiting holes.

[0009] Optionally, a spring washer is fitted at the bottom of the locking rod, and the spring washer is located between the nut and the insulating support rod.

[0010] Optionally, it also includes a pull cord, one end of which is connected to the nut and the other end of which is connected to the ring.

[0011] Optionally, flexible pads are connected to both sides of the operating panel.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. Through the cooperation of the locking rod, nut and spring washer, the locking rod slides in the limiting hole of the insulating support rod and is fixed by the nut. The spring washer at the bottom of the locking rod provides additional pressure when tightening the nut, which enhances the connection stability between the locking rod and the insulating support rod and realizes a stable connection of the wire.

[0014] 2. Through the rotating seat, clamp and locking assembly, the clamp can rotate flexibly to adapt to wires at different angles. By rotating the operating plate, the clamp is pressed against the connecting rod and rubber pad, ensuring that the distance between the wires is stable. Attached Figure Description

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0021] Example: An insulating support rod locking device for live poles, such as... Figures 1-4 As shown, the device includes an insulating support rod 1, a locking rod 3, a nut 4, a ring 5, a rotating seat 6, a clamp 7, and a locking assembly 8. The insulating support rod 1 has fourteen limiting holes 2, seven at each end. A locking rod 3 is slidably connected to the limiting holes 2 of the insulating support rod 1. There is one locking rod 3 at each end of the insulating support rod 1. The bottom of the locking rod 3 is threaded and a nut 4 is threaded to the bottom of the locking rod 3. A ring 5 is rotatably connected to the top of the locking rod 3. A rotating seat 6 is connected to the ring 5. A clamp 7 is rotatably connected to the rotating seat 6. The rotating seat 6 is at the connection point with the clamp 7, and the rotating seat 6 clamps the clamp 7 in the middle. The clamp 7 consists of two arc plates that can rotate. The clamp 7 clamps and fixes the wire through the two arc plates. A locking assembly 8 is provided in the rotating seat 6 to limit the rotation of the clamp 7.

[0022] like Figure 2 and Figure 4 As shown, the locking assembly 8 includes a connecting rod 81, a rubber pad 82, a connecting ring 83, and an operating plate 84. The bottom of the clamp 7 is connected to the connecting rod 81, which is rotatably connected to the rotating seat 6. The rubber pad 82 is connected to one side of the connecting rod 81, and the connecting ring 83 is rotatably connected to the side of the rotating seat 6. The operating plate 84 is connected to the connecting ring 83. The operating plate 84 is press-fitted with the connecting rod 81 and the rubber pad 82. A portion of the connecting rod 81 is missing from the side that contacts the operating rod, and this portion is not covered with the rubber pad 82. The operating plate 84 is provided with a flexible pad 12 that mates with the missing portion of the connecting rod 81.

[0023] After the staff ascends via the ladder, they select the appropriate limiting hole 2 according to the recommended phase-to-phase safety distance between the two conductors. Then, they insert a locking rod 3 into the corresponding limiting hole 2, tighten the nut 4, connect the clamp 7 above to the conductor, tighten the bolt between the two arc plates, and then move to the other conductor to complete the fixing of the clamp 7 and the conductor. Pull the locking rod 3 to separate the two conductors, then insert the locking rod 3 into the limiting hole 2 on the other side of the insulating support rod 1, tighten the nut 4, adjust the distance between the conductors by rotating the clamp 7, and then fix the clamp 7 by the locking assembly 8, thereby completing the fixing of the distance between the guides, which facilitates subsequent work. When removing the insulating support rod 1, the clamp 7 can be released from fixing the conductor.

[0024] When fixing the rotation angle of clamp 7, the operator turns the operating plate 84. When the operating plate 84 rotates, the protrusion on it rotates accordingly and slides against the connecting rod 81. At this time, the operating plate 84 presses against the connecting rod 81 and the rubber pad 82, thereby pressing clamp 7 tightly against the rotating seat 6. At the same time, the connecting operating plate 84 and the connecting ring 83 also press against the rotating seat 6, thereby restricting the automatic rotation of clamp 7 and stabilizing the distance between the wires. Before removing clamp 7, the operating plate 84 needs to be rotated first so that the protrusion on the operating plate 84 is aligned with the notch of the connecting rod 81, so that clamp 7 can rotate freely.

[0025] like Figure 1 As shown, it also includes identification cards 9. The insulating support rod 1 is connected to fourteen identification cards 9. The identification cards 9 correspond to the limiting holes 2. The numbers pasted on the identification cards 9 increase sequentially from the middle to both sides. According to the distance between the two wires, two appropriate limiting holes 2 are selected. The pasted numbers make it convenient for the staff to select the corresponding limiting holes 2.

[0026] like Figure 2 As shown, it also includes a spring washer 10. The bottom of the locking rod 3 is fitted with a spring washer 10. The spring washer 10 is located between the nut 4 and the insulating support rod 1. When the nut 4 is tightened, the spring washer 10 is squeezed. Through the action of the spring washer 10, a stable and reliable connection between the locking rod 3 and the insulating support rod 1 is ensured.

[0027] like Figure 2 As shown, it also includes a pull rope 11, one end of which is connected to the nut 4 and the other end is connected to the ring 5. When the nut 4 is unscrewed, there is no need to collect and place it. The pull rope 11 suspends the nut 4 and moves with the locking rod 3, so there is no need to search for the nut 4 when it is used again. This optimizes the operation steps, saves working time, and improves work efficiency.

[0028] like Figure 2 As shown, it also includes a flexible pad 12. Flexible pads 12 are connected to both sides of the operating plate 84. When the operating plate 84 is rotated, the operator's fingers come into contact with the flexible pads 12, increasing the contact friction and optimizing the stability during rotation.

[0029] After the worker ascends to the working position, they quickly select the limiting hole 2 based on the safe distance between the wires and position it using the identification card 9. The locking rod 3 is inserted into the limiting hole 2, and the spring washer 10 provides stabilizing force when the nut 4 is tightened, ensuring a secure connection between the locking rod 3 and the insulating support rod 1. The rotating seat 6 at the top of the locking rod 3 is equipped with a rotatable clamp 7, which consists of two arc plates to accommodate wires of different diameters and is clamped with bolts. After one clamp 7 is fixed to the wire, it is moved to the other side to complete the same fixation. The locking rod 3 is pulled to adjust the distance between the two wires, then inserted into the limiting hole 2 on the other side and the nut 4 is tightened. The clamp 7 is rotated to fine-tune the distance, and then fixed using the locking assembly 8: the operating plate 84 rotates, the protrusion slides in conjunction with the connecting rod 81, and the pressure pad 82 makes the clamp 7 fit tightly against the rotating seat 6. At the same time, the pressure between the operating plate 84 and the rotating seat 6 restricts the rotation of the clamp 7, stabilizing the wire distance. The pull rope 11 connects the nut 4 and the ring 5, facilitating suspension and movement, saving time and improving efficiency. The flexible pads 12 on both sides of the control panel 84 increase friction and improve operational stability. After the work is completed, release the clamps 7 to remove the device.
