Abstract

The utility model relates to a wrench for installing wire spacing rods. The utility model comprises a rotating support block, a rotating rod symmetrically arranged at both ends of the rotating supporting block, a pair of rotating wrenches symmetrically and fixedly arranged on the rotating rod, and a winding claw fixing block and a winding claw fixedly arranged on the rotating rod. The winding claw fixing block is arranged parallel to the axial direction of the rotary wrench. According to the structural size of the wire spacer, the utility model uses the lever principle to design the spacer wrench. When the wire spacer is installed and removed, the spacer is quickly installed and removed through the leverage principle, and can be used for various four-split wire spacers. demolition.

Description

A wire spacer installation wrench

technical field

The utility model relates to a wrench for installing wire spacing rods.

Background technique

In the current 500kV overhead transmission lines, the sub-conductors are mostly fixed by four-split spacers. Due to the difference in construction time, construction units, and purchasing manufacturers, the types of spacers used in the conductors are diverse, and the corresponding special wrenches also come in various forms. . Due to the variety of types of spacer bars used in the wires, a single job requires operators to carry multiple spacer wrenches of different types, which increases the labor intensity. Sometimes the operation and maintenance work of a line requires operators to carry multiple special wrenches for different types of spacers, which virtually increases the labor intensity of the work. Sometimes the normal progress of the work is affected because the spacer wrench is not universal and the spacer cannot be disassembled.

At present, there are two types of spacers used in the 500kV four-split conductors under the jurisdiction of the work area, one with holes and one without holes, and they use two different special screw wrenches—the eye-inserting rotary type and the double-hook rotary type. These two tools are disassembled after "clamping" using the screw principle, which is inconvenient to operate and takes a long time to complete.

Utility model content

The technical problem to be solved by the utility model is to provide a wire spacer installation wrench which is comfortable to use, fast to install, convenient to disassemble, simple to use and wide in application.

The utility model adopts the following technical solutions:

The utility model comprises a rotating support block, a rotating rod symmetrically arranged at both ends of the rotating supporting block, a pair of rotating wrenches symmetrically and fixedly arranged on the rotating rod, and a winding claw fixing block and a winding claw fixedly arranged on the rotating rod. The winding claw fixing block is arranged parallel to the axial direction of the rotary wrench.

The positive effects of the utility model are as follows:

According to the structural size of the wire spacer, the utility model uses the lever principle to design the spacer wrench. When the wire spacer is installed and removed, the spacer is quickly installed and removed through the leverage principle, and can be used for various four-split wire spacers. demolition.

The utility model utilizes the fixed block of the winding claw and the rotating wrench arranged in parallel. During use, the winding claw is wound on the wire, the wire is used as the axis, and the rotating support block is used as the fulcrum to carry out the rotation operation. At this time, the rotating handle is located outside the lower end. , convenient for users to focus on, using the utility model is more than dozens of times faster than using the old tool, and because of the strong general characteristics, the work efficiency is greatly improved and the labor intensity is reduced.
