Helicopter sling device and method for hoisting phase-to-phase spacers through helicopter sling method

Abstract

The invention provides a helicopter sling device and a method for hoisting phase-to-phase spacers through a helicopter sling method, and relates to the technical field of power transmission line overhauling and maintaining. The helicopter sling device comprises a sling assembly, a lifting hook assembly, a plurality of first locking clam assemblies and a plurality of second locking clam assemblies, wherein the sliding assembly is fixedly connected to the belly of a helicopter; the lifting hook assembly is located below the sling assembly and connected with the sling assembly in a hanging manner; the plurality of first locking clam assemblies are sequentially hung below the lifting hook assembly from top to bottom, each first locking clam assembly comprises a first locking clamp and a first rope sleeve, and each first rope sleeve is located below one first locking clamp and connected with the first locking clamp in a hanging manner; and each second locking clamp assembly comprises a second lock clamp, a third lock clamp and a second rope sleeve which are sequentially connected in series, each second lock clamp is hung on one first rope sleeve located at the lowest position, and each second rope sleeve and each first rope sleeve located at the lowest position are both used for hanging the phase-to-phase spacers. According to the helicopter sling device and the method for hoisting the phase-to-phase spacers through the helicopter sling method, the phase-to-phase spacers can be hoisted through the helicopter.

Description

technical field [0001] The invention relates to the technical field of transmission line inspection and maintenance, in particular to a helicopter sling device used for transmission line operation and maintenance and a method for hoisting interphase spacers by the helicopter sling method. Background technique [0002] With the increasing number of transmission lines, there are more and more operations and construction operations for transmission lines; at the same time, more and more lines are built on high mountains and water, and it is difficult for people and vehicles to reach the above special terrain areas, especially in When maintenance materials with a large volume and weight are required, transportation is difficult and construction time is long, so that it is difficult to complete during a short line power outage maintenance period, and there is a great potential safety hazard in power transmission. For example, in the maintenance of transmission lines, it is often ...

Problems solved by technology

[0002] With the increasing number of transmission lines, there are more and more operations and construction operations for transmission lines; at the same time, more and more lines are built on high mountains and water, and it is difficult for people and vehicles to reach the above special terrain areas, especially in When maintenance materials with a large volume and weight are required, transportation is difficult and construction time is long, so that it is difficult to complete during a short line power outage maintenance period, and there is a large potential safety hazard in power transmission

For example, in the maintenance of transmission lines, it is often necessary to install interphase spacers to prevent transmission lines from galloping. In high mountain areas, if there is no road, they can only be transported by hoist and cableway; The length is longer, because the length is generally more than 10 meters, and some are even as high as more than ten meters, it is difficult for traditional transportation methods to complete the transportation work in the above special terrain

[0003] In view of the above situation, try to use helicopters to carry out large-scale operation of power outage maintenance of transmission lines, but because the length of interphase spacers is generally more than 10 meters, it is difficult to transport by helicopter
