Novel anti-swinging ring of power transmission line anti-falling device

Abstract

The invention discloses a novel anti-swinging ring of a power transmission line anti-falling device. The novel anti-swinging ring comprises a mounting bracket, an anti-swinging ring arc and an anti-swinging ring weight. The mounting bracket is fixedly connected with a fixing member. The side of the anti-swinging ring arc is fixedly connected with the mounting bracket. The side of the anti-swinging ring arc is fixedly connected with the mounting bracket. The anti-swinging ring arc is provided with a gap for passing of an anti-falling device. The anti-swinging ring arc is provided with a plurality of anti-swinging ring weights which can rotate by a certain angle and can snap an anti-falling steel strand. The side of the anti-swinging ring weight is provided with an anti-swinging ring weight clamp for suppressing left-and-right movement. The anti-swinging ring weight clamp is fixed on the anti-swinging ring arc. The anti-swinging ring of the invention can suppress swinging of the steel strand so that zero-distance contact between the steel strand and the anti-swinging ring is formed and furthermore passing of the anti-falling device is not hindered.

Description

technical field [0001] The invention relates to the technical field of tool manufacturing, in particular to a novel anti-swing ring for limiting the swing of the anti-fall steel strand used in the anti-drop device of the steel strand for transmission lines. Background technique [0002] At present, power transmission lines are required to be equipped with anti-fall devices for climbing. There are two types of anti-fall devices: rail-type and steel-strand-type. Among them, steel-strand anti-fall devices are more commonly used and tend to replace the rail-type. However, the higher height of the pole tower now requires the installation of the anti-swing ring of the steel strand anti-fall device, so as to avoid the steel strand from being broken due to the large swing range with the wind. The existing anti-swing rings are all made of different types of steel bars in the form of two upper and lower arcs facing each other to limit the swing range of the steel strands. However, bec...

Problems solved by technology

However, the towers with higher heights now need to install the anti-swing ring of the steel strand anti-fall device to avoid the steel strand from falling due to the large swing with the wind

The existing anti-swing rings are all made of different types of steel bars in the form of two upper and lower arcs facing each other to limit the swing range of the steel strands. However, because the anti-swing rings need to pass through the fall arrester device, the The swing space is still relatively large, and there is constant friction between the steel strand and the anti-swing ring, and the anti-swing ring is easily broken, resulting in damage to the steel strand, affecting the service life, and easily causing construction accidents
