Description

A transmission tower pole-holding waist ring

technical field

The utility model relates to the technical field of electric power construction equipment, in particular to a waist ring for holding a pole of a transmission tower.

Background technique

During the construction of the transmission tower, the pole should be used as a hoisting tool, and the waist ring is an important accessory of the pole. In the prior art, the length of the waist ring is fixed and cannot be adjusted, which results in that each type of pole must use a special matching waist ring, which is limited and lacks versatility.

In addition, at present, the inside of the waist ring is mostly in the form of rollers as the contact force medium between the waist ring and the standard section of the pole, and the roller assembly and the waist ring are directly fixed by welding or bolt connection, so there are the following two problems:

First, it is impossible to dynamically and flexibly adjust the position of the contact medium.

Second, as the jacking height increases, the pole will sway due to strong winds, and there will be a large impact force in the horizontal direction, which will easily damage the roller assembly.
