Manufacturing method of bolt tightening device without power failure

The utility model relates to the field of bolt tightening in electric power production, in particular to a bolt tightening device without power failure.

Background technique:

2. In the power production work, it is necessary to protect the staff from electric shock. During live maintenance, power outage maintenance or engineering acceptance of power transmission lines, the tightening and tightening conditions of wire-side hardware bolts such as jumper drain boards and other wire-side fittings are inspected. The operator needs to use heavy and special tools to enter the work site for work, which is labor-intensive. , low work efficiency and high risk of operation, especially if the equipotential tightening and drainage equipment loosens the heating bolts, there is a high risk. If the personnel equipotential is used to eliminate the defect, there is a great potential safety hazard, so it is very necessary to study a safe and efficient operation technology.

3. In some power production occasions, there are strict requirements for the tightening of bolts, especially large bolts. If the preload force is too small, the load acting on the bolts will quickly loosen the bolts and fall off. If the preload force is too large, it will cause Fatigue failure of bolts. Any incorrect operation, use and management of bolt fasteners may lead to safety production accidents.
