A movable tightening ring lifting mechanism

Abstract

The invention provides a movable binding ring lifting mechanism, and the mechanism is used for lifting a movable binding ring with the pull rope being wound around a tree bamboo to a high place. The mechanism comprises an annular support capable of surrounding the tree bamboo, a plurality of supporting mechanisms which are disposed on the annular support at intervals and used for supporting the movable binding ring and enabling the movable binding ring to remain opened, and an operating rod which is used for lifting the annular support. The mechanism is simple and convenient in operation, and a worker does not need to carry out high-altitude operation, thereby eliminating the potential safety hazards. The mechanism can prevent the movable binding ring from being loosening from the supporting mechanisms and falling off because of the high smoothness of the tree bamboo, reduces the operation difficulty, and saves the operation time.

Description

technical field [0001] The invention relates to a movable tightening ring lifting mechanism. Background technique [0002] During the operation and maintenance of overhead transmission lines, super-high trees and bamboos often occur in the protected areas of line passage corridors. Super-high trees and bamboos will cause line discharge and tripping, which is an important hidden danger that endangers the safe operation of the line. In order to ensure the safe and stable operation of the transmission network, it is necessary to do a good job in clearing the obstacles of super-high trees and bamboos in the channel. The most common species under overhead transmission lines is fast-growing eucalyptus. This tree species has strong adaptability, rapid growth, tall and straight, and can grow to a height of more than 20 meters. The trunks below 10 meters are usually smooth and branchless. Control its falling direction. The fallen trees and bamboos may fall to nearby workers or low-v...

Problems solved by technology

The most common species under overhead transmission lines is fast-growing eucalyptus. This tree species has strong adaptability, rapid growth, tall and straight, and can grow to a height of more than 20 meters. The trunks below 10 meters are usually smooth and branchless. Control its falling direction. The fallen trees and bamboos may fall to nearby workers or low-voltage lines and other facilities, seriously endangering personal and property safety.

For fast-growing eucalyptus and other bamboos with smooth and branchless trunks, the traditional method is to use personnel to climb up the ladder, tie one end of the pull rope to the bamboo, and the staff pulls the other end of the pull rope to control the bamboo. From the perspective of geometric force combined with previous operating experience, one end of the rope must be tied to a height of more than 6 meters above the ground, and the staff can effectively control its inversion by pulling the other end of the rope. This operation method has complicated steps and takes a lot of time. The efficiency is low, and the operator needs to climb to the ladder with a height of 6 meters or more, which belongs to high-altitude operation, and it is easy to fall from high altitude, posing safety hazards
