Electric pole centralizer

Abstract

The invention discloses an electric pole centralizer. The electric pole centralizer comprises a clamp hoop connected onto the top of a jack by a support rod; the bottom of the jack is hinged to the bottom plate; the electric pole centralizer also comprises a base; a withdrawal stop plate capable of being embedded underground is fixedly arranged at the top surface of the base; idler wheels are arranged on the base; clamping parts matched with the bottom plate are arranged at two side surfaces of the base and the outside surface of the clamp hoop; a sleeve is fixedly and coaxially arranged at the top of the jack; the lower end of the support rod is provided with a tube drum; iron pillars are inserted into the tube sleeve and the sleeve; an annular edge is arranged at the lower end of the tube drum; a cross rod is fixedly arranged at the upper end of the tube drum; the clamp hoop is formed by hinging two semi rings together; the two semi rings are locked together by a locking bolt. A detachable hinging part is arranged at the upper ends of the clamp hoop and the support rod. The electric pole centralizer adopting the structure is reasonable in structure, soil and stones at the positive position side of an electric pole can be easily excavated, the electric pole can be smoothly centralized, the fixing is firm, the transfer is convenient, the electric pole is prevented from being broken and the electric pole centralizer is particularly suitable for centralizing the electric pole used for years.

Description

technical field [0001] The invention relates to a pole centralizer. Background technique [0002] Low-voltage overhead lines are lines used by residents and agricultural production. Most low-voltage overhead lines are supported by cement poles. When the cement pole is erected, it is generally hoisted and straightened by a crane, and the erection is very simple. Because the soil is soft when the poles are first installed, the poles during erection often tilt. This leads to the fact that the crane can only erect the second pole after one pole is completely erected, so the erection efficiency is low. For example, the pole centralizer whose Chinese patent number is 201320216893.4 is designed for hoisting electric poles. [0003] After the cement pole is installed, due to factors such as seasonal changes, geological conditions, and operating time, the cement pole is often skewed, which seriously threatens the normal operation of the power distribution line, so it is necessary ...

Problems solved by technology

If the pole tilts during this process, it will be very difficult to straighten the pole. The reasons are as follows: When the pole is straightened, it must occupy the ground space on the upright side. Then, 1. If the earth and rocks in this space are not cleared, then It is necessary to forcefully squeeze the soil and rock, and the required external force is extremely large. Generally, construction machinery, such as cranes, bulldozers, etc., must be used. If the soil and rocks in the space are completed by manually operating the shovel, firstly, the soil and rocks on the surface are relatively hard, and it is difficult to dig with the shovel. Secondly, for the convenience of digging with the shovel, a relatively large amount of upper layer of soil and rock must be dug out before the lower layer of soil and rock can be deeply excavated. Excavating the space on the upright side of the pole is conical with a large upper end and a smaller lower end, so it is time-consuming, labor-intensive, and inefficient. If it is completed by construction machinery such as excavators, there will be problems due to terrain, traffic restrictions, and unbalanced erection costs. high problem

[0005] Chinese patent Nos. 201220200863.X and 201220222955.8 utility model patents disclose two positive rod devices, these positive rod devices use the jacking force of the hydraulic lifting device (jack) to carry out strong righting, and have a certain righting effect, but there are The following disadvantages: 1. It does not have the function of cleaning up the soil
