Automatic up-and-down device of line patrol robot of strain tower

Abstract

The invention relates to an automatic up-and-down device of a line patrol robot of a strain tower. The device comprises a foundation pile, a hoist, a stay wire and a guiding wire, the foundation pile includes a tower welded by angle iron, and is fixedly arranged on the ground separate from the head of the strain tower for certain distance, the hoist is fixed under the foundation pile, the stay wire and the guiding wire are wound at the two ends of a steel strand of the hoist respectively, the stay wire is led out of the side, close to the foundation pile, of the hoist, guided upwardly via fixed pulleys mounted on the foundation pile, and connected to the ground wire of the strain tower via a tower head bridging device mounted on the head of the strain tower, the guiding wire is led out of the other side of the hoist and fixed on a shaft of a group of movable pulleys, the movable pulleys is hung on the stay line outside the fixed pulley at the topmost end, and the stay wire at each side of the movable pulleys is provided with one stopper. According to the device, up and down of the line patrol robot does not need climbing the iron tower manually, labor and material are reduced, the labor intensity is reduced, the personnel safety is ensured, and the work efficiency is improved.

Description

technical field [0001] The invention provides an automatic on-line and off-line device for a tension-resistant pole tower line inspection robot. Background technique [0002] It is known that the robot goes on and off the assembly line to lift the line inspection robot from the ground to the height of the ground line, and hang it on the ground line according to the working position, or remove the robot from the ground line after the line inspection is completed, and safely lower it to the ground. job process. At present, the more commonly used method is the manual-assisted lifting method. This method requires at least one person to climb the tower, hang the tackle, put the insulating rope, assist the robot to find the line, drop the line, etc., and 5 to 6 people pull and release the cable on the ground. Protect the robot; this method requires a lot of manpower and material resources, and there is a potential risk of live work; another way is to use a cantilever truck to rai...

At present, the more commonly used method is the manual-assisted lifting method. This method requires at least one person to climb the tower, hang the tackle, put the insulating rope, assist the robot to find the line, drop the line, etc., and 5 to 6 people pull and release the cable on the ground. Protect the robot; this method requires a lot of manpower and material resources, and there is a potential risk of live work; another way is to use a cantilever truck to raise the robot to the height of the line, and then use personnel to assist on and off the line. This method is suitable for low towers The line requires a large cantilever truck, and the environment of the line should be convenient for the cantilever truck to enter and exit

Japan's Kansai Electric Power Company proposed an on-line and off-line method based on adding an elevator to the tower body, lifting the robot from the ground to the height of the line, and then the movable joints of the elevator complete the line-finding and landing actions of the robot. Due to the multiple degrees of freedom, the elevator has a complex structure and is inconvenient to install

Generally speaking, the existing artificial-assisted robot off-line method has high labor intensity, low work efficiency, and potential safety hazards.
