Description

Technical Field

[0001] This invention relates to the field of power system technology, specifically to an electric lifting mechanism for live-line work on 220kV transmission lines. Background Technology

[0002] Utility poles are a very common sight nowadays, mainly distributed in various corners of cities and countryside. Utility poles are mainly used to support power lines and are made of materials such as steel and concrete. They are named for their tower-like shape. Pole towers play a particularly important role in the safe and stable operation of the power system. When using utility poles, workers are required to perform maintenance, inspections, or troubleshooting. At this time, workers need to climb up the poles to carry out maintenance work.

[0003] There are currently three main methods for climbing power towers: First, the insulated rope ladder method, where ground personnel use insulated ropes to attach the rope ladder and its top to the working position on the live conductor, and workers climb the ladder by hand to reach the equipotential point. Second, the insulated horizontal ladder method, where ground personnel cooperate with tower climbers to pass the horizontal ladder to the working position using insulated ropes; tower climbers then use ropes to secure both ends of the ladder, and equipotential workers move horizontally along the ladder to reach the equipotential point. Third, the method along the insulator string, where equipotential workers climb the tower to the crossarm and use a "two-span, three-short" method to reach the equipotential point via the tension insulator string. However, the current methods for climbing power towers still have the following problems:

[0004] Currently, most methods for climbing power poles on the market involve long working hours. Workers need to climb manually, which consumes a lot of physical strength, especially when working at heights.

Ground workers then place the drone on the two ropes. Tie a bow on the rope to maintain triaxial tension. Correctly install the pulley and lock (both pulleys and locks are 45T). Each lock should be connected to the pulley via two rope loops. Workers carry the rope up the tower to the work site. Manually construct the belay station. Use backups for the webbing, main lock, and rope. Secure the station at two independent and firmly fixed points on the tower, connecting each with two webbing straps. Tie two figure-eight knots on the rope at appropriate locations, using two locks with opposite lock faces for each knot, connecting them to the webbing straps.
