Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of power equipment positioning devices, in particular to a positioning and anti-loosening structure for the anchor bolts of power transmission towers. Background Technique
[0002] When erecting a power transmission tower, anchor bolts need to be installed for positioning and fastening. A bolt is a labor-saving lever that can generate great force by using a spiral motion. Due to its great tightening force, it has been widely used. A bolt can not only fasten two or more components together, but also easily separate the fastened components, making the components convenient for maintenance and replacement. Its functional role is irreplaceable;
[0003] A power transmission tower may encounter continuous strong winds or earthquakes outdoors. At this time, the bolt will be subjected to violent high-frequency vibrations of external forces, and the nut will have a reverse rotation phenomenon. The reverse rotation can reduce the tightening force of the bolt, and will further cause a vicious cycle in which the nut is more likely and faster to reverse rotate under the high-frequency violent vibrations of external forces. Eventually, the nut will loosen and slip off, causing the bolt to completely lose its tightening force, resulting in damage or even collapse of the power transmission tower. Content of the Utility Model
[0004] The purpose of the utility model is to provide a positioning and anti-loosening structure for the anchor bolts of power transmission towers to solve the problems raised in the above background technique.
