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
B, left bar 1 top bind an interim wind rope 10, and the wind rope other end is fixed on the ground, left bar left side, and interim wind rope is with the bar power circuit is vertical excessively;
The present invention relates to power circuit maintenance activity method, particularly adopt double embrace bar mode that the electric pole that crack defect takes place in the middle and lower part is carried out the method that part is removed Replacement and Repair.
Background technology
Aerial power transmission line be in open-air and long-time running in be subjected to various condition influence such as environment and self, cause all kinds of line defcts and hidden danger, therefore the elimination of line defct and hidden danger is the emphasis in the circuit operation maintenance work, to guarantee the operation of aerial power transmission line equipment health and safety.In the production reality, the situation that often has the electric pole crack defect to occur in middle hypomere and need to repair at short notice, particularly be in the hillside when the bar position, both sides, front and back landform is precipitous, and hang with lead wire and earth wire on the bar, be not easy to tear open vertical rod, it is excessive (and for the construction of new frame that the vertical rod workload is torn in employing open, can adopt a right edge tier pole group cube formula to construct), it is short to permit interruption duration simultaneously, under such condition, safety is removed the electric pole defective section steadily at short notice, the new bar section that changes the outfit is a difficult problem to be solved.
Summary of the invention
The purpose of this invention is to provide a kind of assurance overhead power line safety, quick construction, pole replacing operation method for fixed double aluminum alloy holding poles easily.
The object of the present invention is achieved like this: a kind of pole replacing operation method for fixed double aluminum alloy holding poles, comprise the left bar on erecting power lines road, left bar backguy and right bar, right bar backguy, right bar crack defect occurs in middle hypomere, carry out according to the following steps: a, set up secondary pole of herringbone and herringbone primary load bearing pole respectively in right bar and arranged on left and right sides, two wind rope middle parts are separately fixed at secondary pole and primary load bearing pole top, the two ends of two wind ropes are separately fixed on secondary pole and the primary load bearing pole left and right side ground, and two wind ropes are with the bar power circuit is vertical excessively; B, left bar top bind an interim wind rope, and the wind rope other end is fixed on the ground, left bar left side, and interim wind rope is with the bar power circuit is vertical excessively; C, the lifting rope of boom hoisting is arranged on the secondary pole through two pulleys; D, right bar foundation excavation and base water Heibei provincial opera are surveyed; E, use hoisting apparatus hang right bar by hoisting line, and the right bar hypomere cutting of crackle will take place, and remove; F, to use hoisting apparatus to lift new bar by hoisting line in place, handles burr, and opposite joint welds new bar; After g, welding were finished, butt welded seam carried out x-ray inspection or ultrasonic detection, and the weld seam standard is equal to or higher than the II level; After h, Welding Testing were qualified, basic backfill soil was also removed working measure.
The invention has the beneficial effects as follows:
The present invention has reduced setting, helps the security control of setting, has reduced the control of job execution technology, easy construction; Saved carrier simultaneously and changed the bar cost, saved the engineering time, improved power supply reliability, it is one of working system preferably that this working system is applied in the working line defect processing.
Description of drawings
Fig. 1 is the schematic top plan view of pole of the present invention and wind rope and interim wind rope job site layout;
Fig. 2 is the front view of Fig. 1.
Embodiment
Fig. 1 Fig. 2 illustrates, and the present invention includes the left bar 1 on erecting power lines road, left bar backguy 8 and right bar 2, right bar backguy 9, and right bar crack defect occurs in middle hypomere, carries out according to the following steps:
A, set up secondary pole 4 of herringbone and herringbone primary load bearing pole 3 respectively in right bar 2 and arranged on left and right sides, two wind rope 7,6 middle parts are separately fixed at secondary pole and primary load bearing pole top, the two ends of two wind ropes 7,6 are separately fixed on secondary pole and the primary load bearing pole left and right side ground, and two wind ropes 7,6 are with the bar power circuit is vertical excessively;
B, left bar 1 top bind an interim wind rope 10, and the wind rope other end is fixed on the ground, left bar left side, and interim wind rope is with the bar power circuit is vertical excessively;
C, the lifting rope 5 of boom hoisting is arranged on the secondary pole 4 through two pulley 5b, 5a;
D, right bar foundation excavation and base water Heibei provincial opera are surveyed;
E, use hoisting apparatus hang right bar by hoisting line 5, and the right bar hypomere cutting of crackle will take place, and remove;
It is in place that f, use hoisting apparatus pass through the new bar of hoisting line 5 liftings, handles burr, and opposite joint welds new bar;
After g, welding were finished, butt welded seam carried out x-ray inspection or ultrasonic detection, and the weld seam standard is equal to or higher than the II level;
After h, Welding Testing were qualified, basic backfill soil was also removed working measure.
Can adopt bolt and metal sheet to be connected and fixed.Interim wind rope prevents to vibrate in the lifting process, plays firm electric pole effect.
Main Work tool of the present invention and material are prepared:
