Problems solved by technology

[0002] It is well known that high-voltage or ultra-high-voltage lines are the main way of long-distance electric energy transmission, and high-voltage cables are bridges between power supply equipment and electric equipment, and play the role of transmitting electric energy; they are widely used, so failures often occur, and the high-voltage cables used The cables are bare wires. During long-term use, the spacers on the high-voltage cables are "roughly divided into one-shaped, Y-shaped, X-shaped, wooden-shaped or rice-shaped according to the number of lines", and parts are prone to missing parts due to long-term wind force, so Regular maintenance is required; high-voltage cables in heavy ice areas are affected by de-icing operations, which will also cause strand breakage problems; and there are many cases of high-voltage cable system failures caused by high-voltage cables due to construction quality, such as cables on the surface of the line during construction. It is inevitable that small slip marks will be left, and high-voltage cables exposed to the air and affected by acid rain will leave hidden dangers for long-term safe operation; A small number of broken strands; the above faults should be eliminated in time; most of the current maintenance or repairs use a safety belt, and then people stand on the lower high-voltage cable to complete the work, which is not only very inconvenient, but also extremely difficult

Abstract

The invention discloses a standing type high-voltage cable operation device and relates to a high-voltage cable maintenance device. Two sides of a standing plate (13) are respectively hinged with thelower ends of four vertical rods (5) close to the front end and the rear end, grooved wheels (4) are respectively arranged on the outer sides of the upper ends of the four vertical rods, and telescopic rods (22) are respectively arranged between the vertical rods on two sides of the front part of the standing plate and the rear part; a stop lever (9) is arranged between the middles of every two vertical rods on the two sides of the standing plate respectively, and the cable locking device is connected with any vertical rod or any stop lever or any telescopic rod through a pull rope (25). According to the invention, the four vertical rods arranged on the standing plate are respectively hung on a high-voltage cable, and the high-voltage cable is braked by the cable locking device, so stableoperation maintenance on the high-voltage cable is obtained.
