Strain-resistant tower drainage plate bolt tightener

Abstract

The invention relates to an electrical installation tool, namely a strain-resistant tower drainage plate bolt tightener. The strain-resistant tower drainage plate bolt tightener is characterized in that a long and thin insulating rod (1) is arranged, a connecting rod (4) is hinged to the front end of the insulating rod (1) through a rotary shaft (3), the other end of the connecting rod (4) is fixedly connected with a socket wrench (5), and the socket wrench (5) is matched with an end cap of a drainage plate bolt and a nut. The strain-resistant tower drainage plate bolt tightener has the advantages that a maintainer can complete the drainage plate bolt tightening operation by holding the insulating rod by hand, buckling the socket wrench to the end of the drainage plate bolt and then pushing and pulling the insulating rod, so that high risk operation such as climbing and hanging is avoided, safety is achieved, labor is saved, and hot line work can be carried out. The strain-resistant tower drainage plate bolt tightener has the advantages of being simple in structure, low in manufacturing cost, convenient to carry and operate, low in requirement for operation conditions and the like and is expected to become a necessary tool in the industry.

Description

technical field [0001] The invention relates to an electric installation tool, that is, a bolt tightener for a diversion plate of a tension tower. Background technique [0002] The drainage line of the 220kV strain tower is connected to the main line through the drainage plate and bolts. The swaying of the line will cause the bolts to loosen, causing the drain plate to overheat and ablate or even fall off. For this reason, the line maintenance regulations stipulate that the bolts of the drainage plate of the strain tower must be tightened during line maintenance. The current fastening method is mainly the equipotential operation method. The operator climbs the insulating ladder to enter the strong electric field suspension or volt line operation, which is time-consuming, laborious, and extremely risky. In the process of personnel climbing, the wire is both pulled downwards and increases the swing range. When the drainage plate is overheated or about to fall off, it is more...

Problems solved by technology

The current fastening method is mainly the equipotential operation method. The operator climbs the insulating ladder and enters the strong electric field suspension or volt line operation.

In the process of personnel climbing, the wire is not only pulled downward, but also increases the swing range. When the drainage plate is overheated or about to fall off, it is more likely to break, thus causing personal injury or death.
