Support frame for power transmission line

Abstract

The invention discloses a support frame for a power transmission line, which comprises a hoop, an anti-skid gasket, a vertical rod, a cross rod, a bolt and an arc-shaped metal gasket, and is characterized in that the hoop comprises a fixed part and a free part fixedly connected with the fixed part through the bolt; the vertical rod comprises an inner side portion located on the inner side of the hoop, an outer side portion located on the outer side of the hoop, a connecting portion connecting the inner side portion and the outer side portion and a supporting rod located on the connecting portion, and the inner side portion, the outer side portion, the connecting portion and the supporting rod are integrally formed. The anti-skid gaskets are fixedly arranged on the inner side portions, and the transverse rods are fixedly arranged on the vertical rods through the bolts and the arc-shaped metal gaskets. The concrete pole supporting frame has the following advantages that the friction force between the supporting frame and a concrete pole can be enhanced by arranging the anti-skid gaskets; by arranging the vertical rod with the inner side part and the outer side part, the combination area of the vertical rod and the hoop can be increased, and the structural strength is enhanced.

Description

【Technical field】 [0001] The invention relates to the technical field of power transmission equipment, in particular to a support frame for power transmission lines. 【Background technique】 [0002] my country's 35kV to 110kV transmission lines are widely distributed, and most of them use cement poles as wire carriers. According to the relevant regulations of our country, the transmission lines are equipped with lightning protection lines. These lightning protection lines are located above the transmission lines and at the highest point of the poles. The grounding wire of the lightning protection wire is arranged at the cement pole, and the cable stay wire is arranged at the turning or corner of the transmission line at the same time. The device is mainly used to supply power to nearby cities or towns. Therefore, most of them are located in the wild farmland. It often happens that farmers plow the land and hang the cable-stayed wires, which makes the cement poles of the transm...

Problems solved by technology

The device is mainly used to supply power to nearby cities or towns. Therefore, most of them are located in the wild farmland. It often happens that farmers plow the land and hang the cable-stayed wires, which makes the cement poles of the transmission lines tilt. Due to the pulling effect of the wires, it is easy to cause lightning protection. The wire support is bent or broken due to force. At this time, it is necessary to straighten the cement pole, replace the lightning protection wire support, and reinstall and fix the lightning protection wire

[0003] However, since the lightning protection wire support is about 1.5 meters higher than the concrete pole, it is difficult to replace and install the lightning protection wire. Since the lightning protection wire support is installed on the top of the cement pole, the working position is on and above the top of the cement pole, and there is no higher position to hang the safety belt to ensure the safety of the operator, so it cannot be in a reasonable position according to the electrical safety operation regulations. Suspended seat belts, the safety factor is very low, and it is easy to cause casualties of workers falling

[0004] Therefore, in order to solve the above problems, the existing method is to fix the bracket on the utility pole through the hoop, but the pole is fixed on the outside of the hoop, and it is easy to fall off during long-term use, causing a safety accident
