Infinite-rotating-angle anti-galloping spacer wire clamp with locking device and installation and detachment method

Abstract

The invention discloses an infinite-rotating-angle anti-galloping spacer wire clamp with a locking device. The infinite-rotating-angle anti-galloping spacer wire clamp comprises a rotation wire clamp body, a cover plate, a first lining wire clamp and a second lining wire clamp. The rotation wire clamp body and the cover plate are hinged and connected through a hinge shaft. The first lining wire clamp and the second lining wire clamp are embedded in a groove in the inner side of the rotation wire clamp body and a groove in the inner side of the cover plate. A spring bolt is installed on the left side of the lower end of the rotation wire clamp body through a spring bolt pin shaft. A torsional spring is arranged on the spring bolt pin shaft. The position of the spring bolt is limited through a limiting body. A stop rubber blanket is fixed to the position, opposite to the spring bolts, of the right side of the lower end of the rotation wire clamp body. A brake pad is arranged at the tail end of the cover plate, wherein the spring bolt and the brake pad are locked in a matched mode. The invention further discloses an installation and detachment method of the infinite-rotating-angle anti-galloping spacer wire clamp with the locking device. By means of the infinite-rotating-angle anti-galloping spacer wire clamp, wires can freely rotate when not evenly covered with ice, the rotating angle is not limited, the anti-galloping effect is achieved for the wires, and the infinite-rotating-angle anti-galloping spacer wire clamp is reasonable in structure, safe, reliable and convenient to install and detach.

Description

technical field [0001] The invention relates to an auxiliary device for anti-dancing spacers, in particular to an infinite rotation angle anti-dancing spacer wire clip with a locking device, and the invention also relates to the infinite rotation angle anti-dancing spacer wire clamp with a locking device. Installation and removal method. Background technique [0002] Due to the influence of wind, ice, low temperature and other weather conditions all the year round, the wires in the line often experience fatigue vibration in four directions: breeze vibration, secondary pitch vibration, along-line vibration and galloping. Serious damage to towers, wires, hardware and insulators, frequent trips and power outages on the lines, endangering the safe operation of transmission lines, and causing significant economic losses. [0003] At present, the rotation angle of the anti-galloping spacer bar rotary clamps used in power lines is designed to be in the range of 75° to 360°, but in...

Problems solved by technology

Serious damage to towers, wires, fittings and insulators, frequent tripping and power outages of lines, endangering the safe operation of transmission lines, and causing major economic losses

[0003] At present, the rotation angle of the wire anti-galling spacer rotary clip used on the power line is designed within the range of 75° to 360°, but in some galloping areas with large spans, thick ice and strong wind, this angle is not enough

[0004] In addition, the installation of the inner liner clamp and the rotary clamp of the wire anti-friction spacer rotary clamp used on the power line is carried out separately, requiring a second tightening action, which is inconvenient to install

[0005] In addition, after completing the tightening action of the wire dance-proof spacer rotary clamp used on the power line, bolts, flat washers, spring washers, nuts and other fasteners must be installed, or fastened by inserting and locking the retaining pin. It is very inconvenient to lock the wire clamp by installing a cotter pin or inserting and locking the locking pin and rotating the operation. It usually takes three to four actions to lock the wire clamp, which is very inconvenient. great difficulty

Disclosed in the Chinese invention patent CN101694932B is a kind of fast locking clamp, but it cannot be rotated after it is fixedly installed on the wire
