technical field

The utility model relates to a special tool for a split pin electrification repairer of a power transmission line, which belongs to the technical field of special tools for split pins.

Background technique

Cotter pins are a kind of pins, which are commonly used hardware on high-voltage transmission lines. They are widely used in bolts and nails on various clamps. open foot. When in use, it is inserted into the radial holes of bolts, nails, etc., and then the end with long and short open feet is separated into 90 degrees with a tool to fix the nuts that match the bolts, or to prevent the pins from falling off. Prevents the nut or pin from falling off. The cotter pins on the power line are easily corroded by wind and sun. After corrosion, the strength is reduced, and they are easy to break during operation, resulting in failures such as disconnection. Especially in the operation of power transmission lines, defects such as missing pins are often found due to breeze vibration or construction leftovers. In the defect library of primary power transmission equipment, pin breakage, failure, missing, and deformation are listed as critical defects, and must be repaired after discovery. Timely additional processing, in order to eliminate hidden dangers of dropped wires, it is necessary to add cotter pins in time, and reset and write off. At present, the tools for adding live split pins are generally replaced by general-purpose tools for adding spring pins. The work efficiency is low and the labor intensity is high. Tools then become the problem to be solved.

The connecting rod, the insulating rod, the reset hammer, the connecting sleeve and the connecting bolt are all well-known and common equipment in the art, and are all sold on the market.

During use, before adding the cotter pin, combine the alveolar on the first joint with the protrusion on the second joint and fix it on the insulating rod through the connecting bolt; when adding the cotter pin, snap the cotter pin into the pin groove, and prevent the opening and closing opening of the pin from opening through the opening and closing groove of the pin; since the number of the opening and closing grooves of the pin is three, they respectively extend to the three side walls of the connecting rod, so it can be connected from three Add cotter pins in one direction; for the installation of cotter pins at different angles, the angle can also be adjusted by adjusting the position of the combination of the alveolar and the protrusion; the connecting bolt is a self-locking bolt, and the connecting head 1 and the connecting head 2 can be connected Locking; when the cotter pin is inserted into the bolt, use the reset hammer to knock and reset the cotter pin. When the cotter pin is reset in place, push or pull the cotter pin to bend the cotter pin to prevent the cotter pin from fall out of the hole.

The beneficial effect of the utility model is that: it is a special tool which can integrate supplementary cotter pins with electricity, reset and fold-off, has complete functions, is simple to operate, is convenient to use, saves time and effort, and has a broad market space.
