Problems solved by technology

[0015] This kind of replacement technology can only be used for lines that cannot be powered off. It 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 work will be difficult.

Embodiment Construction

[0029] The present invention will be further explained below in conjunction with the drawings.

[0030] See figure 1 The tool provided by the present invention for the live treatment of drain wire clamp bolts includes a connecting rod 3, a sleeve for fastening the bolts 1, an insulating rod 5, and the sleeve 1 is detachably connected to one end of the connecting rod 3. The insulating rod 5 is rotatably connected to the other end of the connecting rod 3 through the connecting piece 4, and the insulating rod 5 can rotate 360° around the connecting rod 3. A ratchet 2 is provided between the connecting rod 3 and the sleeve 1 to prevent the bolts from being loosened instead of being tightened. The ratchet 2 is inserted into the connecting rod 3, and the sleeve 1 and the ratchet 2 pass through a square cone (not shown in the figure). Mark) connection. The above-mentioned insulating rod 5 is formed by connecting insulating rod units, and the insulating rod units can be connected, ...

Abstract

The invention relates to a tool for processing a drainage wire clip bolt under a hot-line mode. The tool comprises a connection rod, a sleeve for fastening the bolt and an insulation rod; the sleeve is detachably positioned at one end of the connection rod; the insulation rod is rotationally connected to the other end of the connection rod; the insulation rod can rotate around the connection rod by 360 degrees. The invention also relates to a hot-line work method by adopting the tool. The insulation rod according to the stress conditions and the insulation conditions is adopted for operation, and the tool according with the mechanical and electrical performance is adopted for performing bolt fastening. In the operation process, the insulation rod can rotate around the connection rod by 360 degrees, the operation step is simplified and the heating defect can be fast handled. The insulation rod is formed by connecting insulation rods, and a safe distance is kept between operation staff and a live conductor according to the needed length of the insulation rod, and the full-process hot-line operation is realized. After the tool is used, the work efficiency is improved, the work cost is reduced and a safe distance according with demands is always kept between a human body and the conductor.

Description

Technical field [0001] The present invention belongs to the technical field of drainage line protection, and in particular relates to a tool that can process drainage line clamp bolts with electricity and a live working method thereof. Background technique [0002] The drain wire and its wire clamp will loosen the fastening bolts due to wind vibration and other factors during operation, which will cause electric discharge between the drain wire and the wire, and the bolts need to be fastened. During the operation of transmission lines, personnel, towers, and overhead ground wires must be kept at a safe distance from live conductors. Depending on the voltage level, the safety distance is also different. Table 1 lists the safety distances corresponding to the voltage levels of common transmission lines. [0003] Table 1 The safety distance between the person and the live object during live work [0004] Voltage level (kV)110220500 Operating safety distance (m)1.01.83.4 [0005] ...
