Abstract

The invention discloses a power transmission line lifting device. The power transmission line lifting device comprises a sliding mechanism and a man-carrying platform. A pull rope is arranged between the sliding mechanism and the man-carrying platform, the upper end of the pull rope is fixed to a left baffle and a right baffle of the sliding mechanism, and the lower end of the pull rope penetrates through a second pulley and a third pulley of the man-carrying platform in sequence to be fixed to a drum of a winch. The sliding mechanism and the man-carrying platform are arranged separately, so that it is only needed to move the sliding mechanism to a position where working is needed and then connect the man-carrying platform to the sliding mechanism, and then harm to the man-carrying platform and workers in the moving process is avoided; besides, the function of automatic lifting of the man-carrying platform and the sliding mechanism is achieved through a motor, so that working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of transmission line maintenance and repair equipment in the electric power industry, in particular to a transmission line lifting device. Background technique [0002] A pulley is usually used in the maintenance work on the transmission line conductor. A section of rope is tied on the pulley, and the free end of the rope is manually pulled by the staff on the tower or the bottom surface to control the sliding speed of the pulley. If the height difference between the two pole towers is large or there are obstacles on the transmission line conductor, the speed of the block is not easy to control, which affects the personal safety of the staff in the block and also brings hidden dangers to the on-site safety work. Contents of the invention [0003] The invention proposes a power transmission line lifting device to solve the problem that there is a safety hazard when the trolley moves on the transmission line...
