Abstract

The invention discloses an electric lifting device for high-voltage transmission line tower working. With regard to the current situation that the present climbing-up and climbing-down working for high-voltage transmission line towers are high in labor intensity, and the frequent accidents of falling injury are caused, the towers are provided with climbing pedals, and some irrelevant personnel privately climb the towers, so that many defects of electric shock injury, power outage and the like are caused, a steel strand fixing frame is installed at the middle of the top of each high-voltage transmission line tower, and a fixing frame is installed at the bottom of the high-voltage transmission line tower; a left steel strand and a right steel strand are fixed to the fixing frames verticallyand in parallel; a steel rope and an upper-end pulley of a lifting winch are driven to the top of the high-voltage line tower through a steel rope tractor, and are automatically locked with the fixingframe at the top; working personnel are carried to climb up and climb down the tower by a storage-battery direct-current winch on the ground; and the climbing-up and climbing-down working is rapid, efficient, safe and reliable, the labor intensity of the working personnel is greatly lowered, climbing-up and climbing-down for the pedals are avoided, the unsafe behavior of privately climbing the towers, of non-working personnel is prevented, and the safe running of a transmission line is effectively improved.

Description

technical field [0001] This patent relates to the technical field of high-voltage line operation, in particular to an electric lifting device for high-voltage line iron tower operation. Background technique [0002] At present, high-voltage transmission line towers; with the increase of voltage level, the line towers are getting higher and higher, the traditional towers work up and down, and the ladder climbing pedals installed are used to climb step by step. When the operators work on and off the tower, the consumption A lot of physical strength and labor intensity are very high, and accidents of falling injuries occur from time to time. Because the iron tower has climbing pedals, some unrelated personnel climb the iron tower privately, resulting in frequent power outages and injury accidents. Contents of the invention [0003] The purpose of this patent is to solve the current high-voltage transmission line iron tower climbing operation, which is labor-intensive, and acc...
