Description
Technical Field
The invention belongs to the technical field of pole rising, and particularly relates to a pole rising device.
Background
The power transmission line channel inevitably passes through mountainous areas due to the characteristics of geographical environment and energy distribution of China. The power transmission line iron tower assemblage in the mountainous area is limited by factors such as terrain, traffic, environmental water conservation and the like, most mountain tower positions cannot be assembled mechanically, and the traditional suspension holding pole assemblage process is still adopted at present.
The iron tower structure of the ultra-high voltage and ultra-high voltage transmission line has various types, the length of the holding pole selected according to the structure characteristics and the weight distribution of the tower is usually 27-45 m, the holding pole has high risk when being erected, the terrain of a mountain area is steep, and the erection difficulty of the holding pole is further increased. For standardizing the pole setting up technology, reducing the safe risk of setting up, specially develop light-dutyization, easy dismouting, simple structure, utilize current tower tool hank to grind and the mechanical lifting pole setting up device of rope as power, filled the blank of suspension pole setting up tool.
The existing suspension holding pole generally adopts the following methods:
(1) integral stand up
Firstly, the falling single holding pole stands up: the standing speed is fast, and it is light to use, but the system of standing up is unstable, and the risk of standing up is great, also faces the difficulty of single pole self standing up simultaneously in mountain region.
Standing the herringbone holding rod: the herringbone holding pole is a holding pole standing mode which is commonly used, the use is convenient, the standing length of the holding pole is limited, the longer the holding pole is, the more complex the standing system is, and the greater the risk is. Meanwhile, the requirement on the terrain for the stand of the holding pole is high, the holding pole needs to have a lengthening condition, and the holding pole is difficult to stand for the full length in mountain areas.
Erecting a crane: the method has the advantages of high standing speed and low construction risk, but has high requirements on fields and transportation, is limited by terrains, and is not suitable for standing in mountain areas.
(2) Erecting by upright installation
The standing speed is high, the operation is convenient, but the standing safety risk is large, and the holding pole is prohibited to adopt a normal installation method in the current safety regulation.
(3) Partially erected and then inverted
When the mountainous terrain condition is poor, the small holding pole is utilized to assemble for 18-24 meters, and then the lower section tower body of the large holding pole or the small holding pole is utilized to reversely assemble the holding pole to a preset height. The method is mostly used for assembling the holding pole in the mountain, but when the lower root of the extra-high voltage iron tower is large and the difference of the high leg and the low leg of the mountain is large, the large holding pole cannot be assembled or cannot meet the requirement of assembling and hoisting the lower tower body, so that the holding pole cannot be inverted.
At present, the tower position paths of ultrahigh voltage and extra-high voltage transmission lines are mostly positioned in dense forests in mountains, the tower footing is designed in an all-dimensional high-low leg mode, the terrain is steep, the environment of an iron tower assembly operation surface is poor, the main material of the iron tower is single and long, the weight is large, and the method for erecting the suspension holding pole is not suitable. Meanwhile, a special assembly construction tool is not used in the flip-chip method, and related process guidance rules are not elaborated in detail, so that the field construction operation method is various, constructors are easy to operate in violation, the safety risk is greatly increased, and safety accidents are frequent.
The suspension holding pole tower assembling process is still the mainstream of the current power transmission and transformation project construction, mountain projects can face the problem of difficult holding pole erection, the erection of the overlong holding pole is a high-risk operation, group death and group injury are easily caused by carelessness, and under the current safety situation, the problem of safe erection of the overlong holding pole is very necessary to solve.
