Background technique

Live pole operation is the work of pulling out, moving or replacing poles without power failure. In order to ensure a sufficient safe distance between the pole and the wires on both sides, it is necessary to use insulating tools to spread the wires on both sides outward for a certain distance. Therefore, the insulating tool that stretches the wire is an important tool to ensure the safety and smooth completion of the live pole work. So far, there is no tool that is really suitable for supporting wires for 10kV live pole work.

Contents of the invention

The invention provides a wire support tool for live pole operation, which ensures that the 10kV live pole operation can be carried out safely and smoothly.

The technical solution adopted by the present invention to solve the technical problem: this wire support tool for live pole operation, one end of the insulating rod is equipped with a fixed strut head, and the other end is equipped with a movable strut that can be movably matched with the insulating rod head.

The movable strut head is connected up and down by a wire slot and a buckle. There are several perforations distributed at one end of the insulating rod. The movable strut head is fastened to the insulating rod through a buckle. The two ends of the buckle are fixed by fixing bolts. The diameter of the buckle is Fixed to the hole through the movable bolt.

The fixed strut head is replaced by a movable strut head, and an insulating rod at one end thereof has a perforation.

The fixed pole head is embedded in the end of the insulating rod and fixed radially by screws.

The wire draw-in slot is connected with a movable hook through a rocker.

The nut of the movable bolt is butterfly-shaped.

The wire clamping groove is made of stainless steel.

The wire clamping groove is covered with protective rubber.

The beneficial effects of the present invention are: 1. The present invention is small in size, smart to use, convenient to operate, and less time-consuming to install and dismantle; 2. The degree of insulation is good, and the mechanical strength also meets the requirements of a 10kV live pole, which is safe and reliable; 3. Control Material cost and labor cost are reduced, and live poles can be operated without power outages, which effectively improves the reliability of power supply; Fourth, it is the premise and basis for the institutionalization and management of pole operations, which promotes The maintenance of the regional power grid ensures the safe and stable operation of the power grid.

Detailed ways

Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

Embodiment 1: In this wire support tool for live pole operation, one end of the insulating rod 1 is equipped with a fixed strut head 2, and the other end is equipped with a movable strut head 3 that can be movably matched with the insulating rod 1. At the same time, it meets the needs of 35mm ² -240mm ² overhead lines. According to the regulations for live pole operation, a safe distance of more than 2.5m should be maintained between the conductors on both sides of the pole, but the farther away from the opening point, the distance between the conductors on both sides The smaller the distance is, to keep the distance between a section of conductors at a safe distance, the width of the conductor must be greater than 2.5m. According to the sampling test, when the conductor is stretched to 2.8m, the conductors within the range of 10.9m on both sides of the stretch point The distance can meet the safety requirements of more than 2.5m. Because movable strut head 3 is housed, when taking into account the small span, the safety range of the wires on both sides will become smaller. In this embodiment, the length of insulating rod 1 is set to 3m. From the perspective of mechanical strength and operational flexibility, the diameter of the insulating rod 1 is set to 3 cm. The insulating rod 1 of this specification is the main material, and a 90kV withstand voltage test is performed on it for 5 minutes to meet the insulation requirements for 10kV live pole operation. The maximum stress of the insulating rod section is 1760N, which meets the mechanical strength requirements.

The movable strut head 3 is connected up and down by a U-shaped wire slot 3-1 and a buckle 3-2, stainless steel is used as the main material of the wire slot 3-1, the price is moderate, the mechanical strength is high, and it is corrosion-resistant. It is covered with a layer of rubber to prevent it from wearing and tearing the bare wires. The wire clamping groove 3-1 width is set as 3.5cm, can satisfy the needs of various diameter wires. Paste the limited width sign 6 at the 2.5m place of the insulating rod 1, then punch a perforation 4 slightly larger than the bolt behind the sign, and punch a hole every 15cm thereafter, and have 4 perforations 4 altogether. When installing the movable strut head 3, first buckle the buckle 3-2 on the insulating rod 1, and the two ends of the buckle 3-2 are fixed by the fixing bolts 3-3. Rod 1 moves upward, and the clasp is fixed radially at the perforation 4 at a suitable distance through the movable bolt 3-4. Since the operator wears insulating gloves when performing operations, the nut of the movable bolt 3-4 is designed as a butterfly shape. Easy to operate. Wire clamping groove 3-1 is connected with movable hook 3-6 by shaking skin 3-5, and movable hook 3-6 can be flipped, and when wire clamping groove 3-1 blocks wire, wire can press down movable hook 3-6 one end , so that the other end of the movable hook 3-6 is flipped up to cover the opening of the wire clamping groove 3-1, preventing the wire from slipping out, and the use is more stable, safe and reliable.

Described fixed strut head 2 can be replaced by movable strut head 3, only has a perforation 4 at its one end, and it is fixed dead with fixed bolt 3-3 and movable bolt 3-4.

When in use, first spread the wires on one side with the fixed strut head 2, and then adjust the movable strut head 3 to the appropriate perforation 4 according to the safe distance between the wires, and tighten the movable bolts 3-4. Strut head 3 supports the other side lead.

Embodiment 2: Both the insulating rod 1 and the movable strut head 3 are the same as those described in Embodiment 1, and the fixed strut head 2 is embedded in the end of the insulating rod 1 and fixed by screws 5 in the radial direction.

In addition to the above-mentioned embodiments, the present invention can also have other implementations. All technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
