Problems solved by technology

In actual production, it is often the case that the crack defect of the pole occurs in the middle and lower sections and needs to be repaired in a short time, especially when the pole is located on a hillside, the terrain on the front and rear sides is steep, and there is a ground wire hanging on the pole, which is not easy to disassemble. Pole, the workload of dismantling the vertical pole is too large (and for the construction of the new frame, the construction can be carried out by the right side row of poles), and the power outage time is allowed to be short. Under such conditions, it is safe and secure in a short time It is a difficult problem to be solved to remove the defective section of the pole and replace it with a new section

Embodiment Construction

[0014] figure 1 figure 2 It is shown that the present invention includes a left rod 1, a left rod cable 8 and a right rod 2, and a right rod cable 9 for erecting power lines. The crack defect of the right rod occurs in the middle and lower section, and proceed as follows:

[0015] a. On the left and right sides of the right pole 2, a herringbone auxiliary pole 4 and a herringbone main bearing pole 3 are respectively erected, and the middle parts of the two wind ropes 7, 6 are respectively fixed on the top of the auxiliary pole and the main bearing pole. , The two ends of the two wind ropes 7, 6 are respectively fixed on the left and right ground of the auxiliary pole and the main bearing pole, and the two wind ropes 7, 6 are perpendicular to the power line of the pole;

[0016] b. A temporary wind rope 10 is tied to the upper part of the left pole 1, and the other end of the wind rope is fixed on the ground on the left side of the left pole, and the temporary wind rope is perpendi...

Abstract

The invention discloses a pole replacing operation method for fixed double aluminum alloy holding poles, which comprises erection of a left pole and a right pole of an electric line, wherein the cracking defect of the right pole occurs at the middle lower section, and the erection is carried out by the following steps that: a herringbone secondary holding pole and a main bearing holding pole are erected at the left side and the right side of the right pole respectively, two wind ropes are fixed on the left ground and the right ground of the two holding poles respectively, and the two wind ropes are vertical to the over-pole electric line; a temporary wind rope is tied at the upper part of the left pole, the other end of the wind rope is fixed on the ground, and the temporary wind rope is vertical to the over-pole electric line; a hoisting device is arranged on the secondary holding pole; the right pole is hoisted by using the hoisting device, the lower section of the cracked right pole is cut and removed, and then a new pole is hoisted in place and is welded at butt seam; and the seam inspection is carried out after the welding is finished, then soil is filled back a foundation after the seam is qualified, and the construction measures are removed. The pole replacing operation method for the fixed double aluminum alloy holding poles has the characteristics of safe and quick construction.

Description

technical field [0001] b. A temporary wind rope 10 is tied to the upper part of the left pole 1, and the other end of the wind rope is fixed on the ground on the left side of the left pole, and the temporary wind rope is perpendicular to the power line passing through the pole; [0002] The invention relates to a power line maintenance operation method, in particular to a method for partially dismantling, replacing, and repairing electric poles with crack defects in the middle and lower parts by means of double-holding poles. Background technique [0003] The overhead power transmission line is in the field and is affected by various conditions such as the environment and itself during long-term operation, resulting in various line defects and hidden dangers. Therefore, the elimination of line defects and hidden dangers is the focus of line operation and maintenance to ensure that overhead power transmission line equipment Healthy and safe operation. In actual production, ...
