A pulley for high-altitude lines or pipe diameters and its installation method

Abstract

The invention provides a pulley for a high-altitude line or pipe diameter, and a mounting method thereof. The pulley for the high-altitude line or pipe diameter comprises a left pulley device, a right pulley device, and a transverse connecting rod for connecting the left pulley device and the right pulley device, wherein each pulley device comprises a fixed pulley, a fixed pulley component arranged on the two sides of the fixed pulley, and a hook arranged at the top of the fixed pulley component; and the transverse connecting rod is arranged at the tops of the hooks. The hooks of the pulley provided by the invention are in shapes of circular arcs with the angles of 250 DEG, connecting angles between the pulley components and arc surfaces are 50 DEG, the pulley can be mounted and fixed on the needed pipe diameter or line on the ground through a rope to hoist heavy weights to high altitude, and can be detached from the high-altitude pipe diameter or line on the ground, so that the pulley can be mounted and detached on the ground, ascending operation is not needed, and dangers of ascending operation are prevented from occurring.

Description

Technical field [0001] The invention relates to a device for the maintenance of power transmission and transformation lines, in particular to a pulley for high-altitude lines or pipe diameters that can be hooked and disassembled on the ground and an installation method thereof. Background technique [0002] At present, when hooking pulleys on high-altitude lines or pipe diameters, people need to climb up to fix the pulleys on the high-altitude lines or pipe diameters, and then pass the rope through the pulleys to use the pulleys. The use of pulleys can greatly improve work efficiency, but there is a certain danger in personnel climbing operations, especially in some large-span high-altitude lines or pipe diameters, such as tens or hundreds of meters of power transmission lines, and climbing operations are difficult. Common pulleys Or pulley block, all need to be installed by personnel climbing, and need to be removed after use. Therefore, designing a new type of pulley that does...

AI Technical Summary

Problems solved by technology

The use of pulleys can greatly improve work efficiency, but there are certain dangers in personnel climbing operations, especially in some long-span high-altitude lines or pipe diameters, such as tens or hundreds of meters of power transmission wires, climbing operations are extremely difficult, ordinary pulleys Or the pulley block, both need to be installed by personnel, and need to be dismantled after use
