Description

An Auxiliary Caliper for Accurately Measuring the Inclination of UHV DC Transmission Line Tower

technical field

The utility model relates to the technical field of tools and equipment, in particular to an auxiliary caliper for accurately measuring the inclination of a UHV DC transmission line tower.

Background technique

In the daily operation and maintenance of transmission lines, for towers in areas such as landslides, side slope collapses and cracks, inspectors need to measure the inclination of towers. The following figure shows the inclination of towers measured by operation and maintenance personnel on site. The following problems exist:

1. During the measurement process, in order to cooperate with the theodolite operator to get accurate readings, the cooperating personnel need to climb the tower to the Dalian plate, the first platform of the tower, and there is a risk of climbing operations during the tower climbing process;

2. After the auxiliary measuring personnel arrive at the connecting plate, they need to use a tape measure to assist in the measurement at the horizontal row of bolts. There are human operation errors in the process of drawing the ruler, such as inaccurate position, tape measure slanting, shaking, etc.;

3. During the process of drawing the ruler, due to the narrow working position at the connecting plate, the auxiliary surveyors may block the tape measure and affect the readings of theodolite operators. Therefore, we improve this and propose an auxiliary caliper for accurate measurement of the inclination of UHV DC transmission line towers.
