Live working robot and live wire cutter

Abstract

The invention relates to a live-line work robot and a pair of live-line wire cutters. The electrified wire cutters comprise a mechanical execution part and an electric driving part, wherein the mechanical execution part comprises a movable cutter, the electric driving part is used for providing power for the mechanical execution part, the electric driving part is in transmission connection with the mechanical execution part through a transmission rod, the transmission rod is an insulating rod, the transmission rod is sleeved with an insulating protection sleeve, the insulating protection sleeve can prevent flashover, and the insulating protection sleeve, the electric driving part and the mechanical execution part jointly define the protection space used for protecting the insulating rod. The electrified wire cutters are advantaged in that the insulating protection sleeve can protect the transmission rod, and flashover of the transmission rod is avoided; the protection sleeve is matchedwith the transmission rod, so the transmission requirement can be not only met, but also the anti-flashover requirement can be met, a discharge protection problem of a transmission structure betweenthe mechanical execution part and the electric driving part is solved, and safe and stable operation and the service life of the electric driving part are guaranteed.

Description

technical field [0001] The invention relates to a live working robot and a live wire cutter. Background technique [0002] In order to improve the automation level and safety of live work, the live work is usually carried out by a high-voltage live work robot instead of the operator. The wire cutters used for high-voltage live work are important working tools for high-voltage live work robots. The wire cutters are also called wire cutters, and their main function is to cut off power cables. [0003] Wire cutters in the prior art, such as a Chinese invention patent application with application publication number CN102615217A and application publication date of August 01, 2012, disclose a special voice-activated wire cutter for high-voltage live working robots, including mechanical actuators and electrical components. Drive parts, mechanical execution parts include fixed cutter, movable cutter, oil cylinder and oil pump, electric drive parts include motor, control circuit and...
