Description

Ground wire lead lifting device for high-voltage line iron tower

Technical Field

The utility model relates to a hoisting device technical field specifically is a high tension line iron tower ground wire lead wire hoisting device.

Background

A stay wire type ground wire: the pull wire is used as the ground wire of the ground body. Specifically, the suspension wire is communicated with the pull wire to be used as a ground wire, or the suspension wire is led out from the pull wire and extends out of the top end of the electric pole. In the maintenance of distribution lines of 10 kv and below, in order to prevent backward power transmission to the line being maintained and to avoid endangering the personal safety of workers, it is common practice to install working ground wires at both ends of each working area and at branches (including users) where backward power transmission is possible. Although the installation of a working grounding wire is the simplest and most effective safety technical measure, the reverse power transmission can be prevented, and the induced electricity can be eliminated, but the hanging of the working grounding wire has higher requirements for the embedding of a temporary grounding body. At present, portable short circuit grounding wires for construction in a system are all provided with temporary grounding bodies with the diameter of 16 mm and the length of 750 mm, which completely meet the requirements in an ideal grounding environment and are convenient to apply. However, in order to reach a specified depth of 0.6 m in application along with implementation of rural road hardening engineering, constructors often use an iron hammer to fiercely hit the grounding body, so that the phenomena of bending deformation of the grounding body, cracking of a welding point, loosening of a screw of a grounding lead, poor contact caused by thread damage and the like are common, and a plurality of potential safety hazards also exist. If a permanent grounding body is pre-buried beside the electric pole which is often required to be provided with a working grounding wire to replace the current temporary grounding body, the application is more convenient during working. An iron tower grounding wire is formed by burying 8-12 mm steel bars underground, welding flat irons at the end parts of the steel bars and connecting the steel bars with the bottom of a tower body through bolts. During maintenance at ordinary times, the bolt needs to be dismounted, the grounding resistance of the grounding wire is measured, and the grounding wire is connected with the tower body after normal operation. During actual work, due to the reasons of sinking of soil around the tower body, deformation of the ground wire and the like, after the ground flat iron bolt is detached, the ground wire reinforcing steel bar is pulled down, so that the flat iron at the head of the ground wire cannot be installed in the original position of the tower body again.

In the high-voltage line iron tower ground wire lead wire lifting device disclosed in the chinese utility model patent application publication specification CN104577873A, although this lifting device possesses the effect of promotion, this high-voltage line iron tower ground wire lead wire lifting device, it is weak to have a supporting capacity, and the installation is carried inconveniently, needs manually operation's shortcoming.
