Improved concrete transmission and transformation electric power circuit pole and production method thereof

Abstract

The invention relates to an improved concrete transmission and transformation electric power circuit pole and a production method thereof. The method comprises the steps that an electric pole cage-shaped framework is manufactured; a steel wire is wound automatically; an electric pole top part baffle board and a root part anchoring plate are manufactured; the electric pole cage-shaped framework is subjected to concrete grouting and centrifuging; and electric pole maintenance is conducted, an electric pole with the top diameter portion being in a circular truncated cone shape and a base being provided with a flange is obtained, the diameter portion of a metal baffle board body is anchored and attached with an electric pole steel mold top part end plate, the root part anchoring plate and the electric pole steel mold end plate are anchored and attached, the electric pole top part baffle board and the root part anchoring plate are bushed into the inner wall of an electric pole steel mold, and an inner hole is formed in the middle of the metal board body. By the adoption of the method, the electric rod root part and the top part can be made flat after being formed, and the root part end face impact probability of the electric pole in the hoisting or transporting process is lowered; and meanwhile, in the centrifugal forming process of the electric pole, due to the fact that a top part baffle board boss and an anchoring plate chamfer boss are bushed into the electric pole steel mold, a sealing effect is achieved, and the grout runout phenomenon of the electric pole top part and root part end face is reduced.

Description

technical field [0001] The invention relates to the technical field of production of power transmission and transformation power line products, in particular to an improved production method of concrete power transmission and transformation power line poles. Background technique [0002] The prestressed poles of power transmission and transformation lines that we usually see are generally cylinders with one big end and a small end. After being installed on site, the small head is upward, the top is called slightly, and the bottom with a big head is called the root. The root is equipped with an anchor plate. It is further divided into flat end anchor plates and boss end anchor plates. Ordinary poles use flat end anchor plates, and prestressed poles use boss end anchor plates. The currently used flat end anchor plates and boss end anchor plates are the largest The disadvantage is that the sealing of the anchor plate at the end is poor, and the grout retaining metal plate at th...

[0002] The prestressed poles of power transmission and transformation lines that we usually see are generally cylinders with one big end and a small end. After being installed on site, the small head is upward, the top is called slightly, and the bottom with a big head is called the root. The root is equipped with an anchor plate. It is further divided into flat end anchor plates and boss end anchor plates. Ordinary poles use flat end anchor plates, and prestressed poles use boss end anchor plates. The currently used flat end anchor plates and boss end anchor plates are the largest The disadvantage is that the sealing of the anchor plate at the end is poor, and the grout retaining metal plate at the tip is also flat. When the concrete is poured and centrifuged, it is easy to cause the grout defect on the tip and root end of the pole, and it is easy to produce grout defects during hoisting or The end face of the pole root is easy to be damaged during transportation; the installed concrete power pole is also ugly, so the manufacturers of concrete power line poles do not want this situation to happen
