Description

A device and method for hanging and dismantling anti-falling ropes using drones

technical field

The invention relates to a device and a method for hanging and removing an anti-fall rope by using an unmanned aerial vehicle.

Background technique

In recent years, my country's social economy has continued to develop, and the scale of EHV/UHV power grids has gradually expanded. As the main artery of electric energy transmission, the overhead transmission line must have extremely high operational reliability, and it is necessary to climb the tower to eliminate the fault of the overhead transmission line. High, uneven supplier quality, time-consuming and labor-intensive use of seat belts alternately, seriously affect the safety of tower climbers.

Although the installation coverage of high-altitude fall protection devices for overhead transmission lines in my country has increased significantly in recent years, there are problems that cannot be ignored in the actual promotion and application process. Usually, the towers put into operation in the early stage of my country's overhead transmission lines are only equipped with spikes or ladders, and the anti-fall guide rails have not yet covered all the towers due to cost reasons.

Due to the short promotion time of anti-fall guide rail devices in our country, a series of problems have appeared in the process of promotion and application. For example, the quality of guide rail devices provided by anti-fall guide rail suppliers is uneven, and the specifications and materials of guide rails produced by different manufacturers have not yet been unified. Caused the inconvenience in the use, maintenance process, and then caused the large-scale application of anti-fall guide rail device to have bigger difficulty. Since the anti-fall guide rail device is usually multi-section guide rail and installed in multiple combinations, it is easy to fail to cooperate with the anti-fall device due to poor assembly quality during the installation process.

Secondly, since the anti-fall guide rail is exposed to the natural environment for a long time, it must face harsh conditions such as high air humidity, external temperature, and external force impacts, which may easily lead to corrosion and corrosion of the steering part and track joints of the guide rail. Bending, which in turn causes sliding jamming of the fall arrester, hinders the climbers from climbing the tower, and seriously affects the work efficiency of the climbers.

At present, the traditional tower anti-drop devices of overhead transmission lines in my country include foot nails, safety belts and anti-fall hooks. This device has the characteristics of low cost and simple operation during installation and use, and is in line with the usage habits of tower operators. During use, tower climbers climb the tower step by step by alternately using the anti-fall safety belts. However, this anti-falling device has the disadvantages of time-consuming and labor-intensive use. The alternate use process is cumbersome, the climbing speed is slow, consumes more physical strength of the operators, and seriously affects the operation safety and work efficiency.

the method comprises the following steps: installing a high-altitude suspension assembly on a second mechanical arm, lifting the high-altitude suspension assembly by a lifting hook, fixing the lifting hook on a lifting unmanned aerial vehicle by two insulating ropes, fixing one end of a falling-prevention rope on a suspension bolt, lifting the device by the lifting unmanned aerial vehicle, enabling the device to be in a lifting state, lifting the second mechanical arm to trigger the first mechanical arm to fall off the limitation of the second mechanical arm, allowing the first mechanical arm to droop under the action of self gravity, opening a locking device, and allowing the lifting unmanned aerial vehicle to lift the device to fly above a target cross arm from the ground;

step two: the flying hand accurately controls the lifting unmanned aerial vehicle to gradually approach to the tower material to be hung, the lifting unmanned aerial vehicle is hovered after the auxiliary unmanned aerial vehicle determines that the lifting unmanned aerial vehicle reaches the position right above the optimal position suitable for the hanging device, then the flying hand controls the lifting unmanned aerial vehicle to vertically descend, the target tower material enters an opening, and the lifting unmanned aerial vehicle is controlled to move and separate after the device is confirmed to be completely attached to the tower material;

step three: after the high-altitude suspension assembly is separated from the lifting hook, the high-altitude suspension assembly inclines to one side due to self weight and simultaneously drives the second mechanical arm to generate downward displacement, so that the second mechanical arm is in contact with the first mechanical arm to realize position locking corresponding to the first mechanical arm, and at the moment, the device forms complete sealing for the suspended tower material;

step four, the tower climbing operation personnel realize the tower climbing operation through the anti-falling rope connected on the device;

step five: after the operation is finished, after an operator goes down the tower, the flying hand operates the lifting unmanned aerial vehicle to carry the detaching ring to fly to the hanging point of the fixing device, and the detaching ring is used for detaching the device;

step six: the disassembling ring lifts the high-altitude suspension assembly to drive the second mechanical arm to lift upwards to trigger the first mechanical arm to be separated from the contact of the second mechanical arm, at the moment, the first mechanical arm sags due to self weight, and the locking device is unlocked; and finally, lifting the unmanned aerial vehicle, lifting the lifting device, separating the detaching ring from the target tower material, flying away from the tower body, and safely descending to return to the ground.
