Description

A tool for handling drain wire clamp bolts with electricity

technical field

The utility model belongs to the technical field of drainage wire protection, in particular to a tool capable of handling the clamp bolts of the drainage wire with electricity.

Background technique

During the operation of the drain wire and its clamp, the fastening bolts will loosen due to wind vibration and other factors, which will cause discharge between the drain wire and the wire, and the bolts need to be tightened. During the operation of transmission lines, personnel, towers and overhead ground wires must keep a certain safe distance from live conductors. According to different voltage levels, the safety distance is also different. Table 1 lists the safety distances corresponding to common transmission line voltage levels.

Table 1 Safety distance between the person and the live body during live work

Voltage level (kV) 110 220 500 Operating safety distance (m) 1.0 1.8 3.4

In order to ensure the above-mentioned safe distance and avoid accidents such as discharge and electric shock, the existing bolt tightening operation is completed based on power failure conditions or electrified equipotential conditions. The main tools used under power failure conditions are: wrench, wooden ladder, etc. The process of fastening bolts is as follows:

First, the person in charge of the work applies to the dispatcher for load transfer and power outage operations on the operation line;

Second, the operator climbs to the loose bolt through the wooden ladder, tightens it with a wrench and returns to the ground;

Third, the person in charge of the work reports to the dispatcher that the work is completed and the power transmission is resumed.

This replacement technique is cost-effective for fastening bolts in large areas, but if only one or two bolts are fastened, it is necessary to perform power-off operations and repeat the arrangement of work tools during each replacement process , which will seriously affect the reliability of the line.

The main tools used under charged equipotential conditions are: wrench, soft ladder, shielding suit, etc. The process of fastening bolts is as follows:

First, the person in charge of the work applies to the dispatcher for the deactivation and reclosing operation of the operation line;

Second, the auxiliary personnel board the pole and hang the soft ladder on the guide line;

Third, the operator wears the shielding suit and climbs through the soft ladder to the loose bolt, tightens it with a wrench and returns to the ground;

Fourth, the person in charge of the work reports to the dispatcher that the work is completed and resumes reclosing.

This kind of replacement technology can only be used for lines that cannot be powered off, and is not suitable for fastening bolts in large areas or in a few places. The arrangement of operating tools must be repeated every time, which will seriously affect the reliability of the line. In addition, if the work site is located in a mountainous area and other areas, the ladders cannot be arranged according to the requirements of the work instructions, and the replacement operation will be difficult.

Utility model content

The utility model overcomes the deficiencies in the prior art, and provides a tool for handling drain wire clamp bolts which can keep operators at a safe distance from live wires, realize live work in the whole process, and have a wide application range.

The concrete technical scheme of the utility model is as follows:

A tool for handling the clamp bolts of drain wires with electricity, including a connecting rod, a sleeve for fastening the bolts, and an insulating rod. The sleeve is detachably connected to one end of the connecting rod, and the insulating rod is rotatably connected to the At the other end of the rod, the insulating rod can rotate 360° around the connecting rod.

An anti-reverse rotation device is provided between the connecting rod and the sleeve to prevent the bolt from being loosened instead of being fastened. The anti-reverse rotation device described in the utility model is preferably a ratchet.

The insulating rods are formed by connecting insulating rod units, and the insulating rod units can be connected, which is suitable for different distance requirements.

The utility model adopts the insulating rod conforming to the stress condition and insulating condition to operate, and utilizes the tool conforming to the mechanical and electrical performance to handle the clamping bolt of the drainage wire to fasten the bolt. During the operation, the insulating rod can rotate 360° around the connecting rod, which simplifies the operation steps and quickly solves the heating defect. The insulating rods are connected by insulating rod units, and the length of the insulating rods is determined according to the needs to keep a safe distance between the operator and the live wires, so as to realize the live working in the whole process. After using the utility model, the work efficiency is improved, the work cost is reduced, and the human body always maintains a required safety distance from the wire.
