Auxiliary pole setting device for rural power grid pole
Technical Field
The invention belongs to the field of rural power grid construction, and particularly relates to an auxiliary pole setting device for a rural power grid pole.
Background
In the construction of agricultural networks, the assembly of electric poles is a vital link. At present, the pole setting modes commonly used in the industry mainly comprise a crane pole setting method, a fixed herringbone pole setting method and a pole setting machine pole setting method, however, the methods have certain limitations and challenges in practical application.
1. Vertical rod method of crane
The crane pole setting method takes the dominant role in pole assembly work by virtue of the strong lifting capacity. The electric pole lifting device can rapidly and accurately finish lifting and assembling of the electric pole, and remarkably improves construction efficiency. However, the crane erection is relatively costly, which undoubtedly increases the economic burden for rural network construction in small or remote areas. Furthermore, in complex terrain or confined spaces, the operational flexibility and efficiency of the crane can be severely compromised and even not accessible to the construction site, which limits the range of application of the method.
2. Method for fixing herringbone holding pole and erecting pole
The fixed herringbone pole setting method becomes an alternative scheme in places where a crane cannot enter. The method keeps stability through a flat and solid foundation and reasonably distributed cable ropes, and has certain adaptability to the assembly of the electric pole. However, the fixed herringbone pole setting method has extremely high experience and technical requirements for operators. In the operation process, the main traction rope, the tail rope, the tower center and the pole top are required to be kept on the same straight line, and the pole top is required to be provided with a temporary stay wire. These complex operating requirements not only increase the construction difficulty, but also, once improperly operated, can easily cause the pole to topple over, resulting in personnel injury or pole damage.
3. Pole erecting method of pole erecting machine
The pole erecting machine pole erecting rule assists the assembly of the electric pole through an electric winch or a hand winch. The method solves the problem that the crane cannot enter to a certain extent, but has a plurality of defects in practical application. Under the scene of no power supply in the open-air, the use of electronic hank mill is restricted, and hand hoist engine then is higher to the physical demands of operating personnel, leads to the efficiency of construction low easily. In addition, the pole erecting method of the pole erecting machine also needs a plurality of operators to mutually cooperate, and the labor cost is high.
