Embodiment approach

[0039] Further, please refer to Figure 1-3 As shown, as a specific embodiment of an anti-loosening device for preventing bolts from loosening provided by the present invention, the anti-loosening hole 11 is a polygon with the same shape as the nut or a regular dodecagon.

[0040] The above-mentioned anti-loosening hole 11 is designed as a polygon with the same shape as the nut, which can ensure a good fit with the nut and has a better anti-loosening effect; There is no need to consider the angle between the nuts, so the applicability is stronger, and it can also play the role of anti-loosening.

[0041] Further, please refer to Figure 1-3 As shown, as a specific embodiment of the anti-loosening device for preventing bolt loosening provided by the present invention, the upper surface of the support frame 3 is also provided with a handle 1, the handle 1 is rod-shaped, and the handle 1 is connected to the support Frame 3 can be a fixed form or a foldable form. When it is a fo...

Abstract

The invention discloses an anti-loosening device for preventing bolt loosening, and belongs to the technical field of tools or accessories for loosening preventing of UHV transmission line drainage connecting bolts. The anti-loosening device comprises a supporting frame and at least one sliding support in sliding connection with the supporting frame through a first sliding device in the first direction, and each sliding support is provided with at least one polygonal anti-loosening hole clamped to a nut of the bolt. The anti-loosening device can solve the technical problem that in the prior art, a bolt at the position of a drainage plate is prone to loosening, and the technical effect of preventing bolt loosening can be achieved.

Description

technical field [0001] The invention belongs to the technical field of tools or accessories for anti-loosening bolts used for drainage and connection of UHV transmission lines, and more specifically relates to an anti-loosening device for preventing bolts from loosening. Background technique [0002] Due to the large number of transmission lines in my country, the daily maintenance and testing work of the inspection unit is becoming increasingly heavy. During the maintenance and testing of transmission lines, it is often found that the bolts at the UHV diversion plate are loose due to factors such as long running time and wind damage. As a result, the contact between the diversion plate and the clamp is not close enough, so that the electric field at the diversion plate changes, causing the diversion plate to overheat, affecting the safe and stable operation of the line. Contents of the invention [0003] The object of the present invention is to provide an anti-loosening d...
