Abstract

The invention discloses a lifting device for an on / off wire of ice coating removal equipment for a transmission line, which comprises a support (5). The lifting device is characterized in that the support (5) is a quadrangular support, an upper edge (8) of the quadrangular support (5) is provided with a wire-guard wide soft band (7), and end parts of the wire-guard wide soft band (7) are connected with a draw rope (6); and a lower edge (3) of the quadrangular support (5) is provided with a pulley (2), the pulley (2) is provided with a lifting rope (10), and one end of the lifting rope (10) is connected with a lifting ring (1). The lifting device is an on / off wire lifting device which is designed for the ice coating removal equipment for the transmission line which can get across porcelain insulators. The lifting device can send the ice coating removal equipment onto an electric wire or send the ice coating removal equipment to the ground from the electric wire through ground operation under the condition without personnel on an iron tower, and prevent the personnel from performing dangerous operation on the iron tower which lifting equipment fails to reach and is coated with ice and snow.

Description

technical field [0001] The invention relates to the technical field of removing ice layers on high-voltage transmission lines in freezing rainy and snowy weather and the on-line and off-line technical field of ice-coating removal mechanical devices, and in particular to a sling used for on-line and off-line of power transmission line ice-coating removal equipment. Background technique [0002] In recent years, due to climate change, freezing rain has occurred in many areas of our country, which has frozen thick ice layers on high-voltage transmission lines, increased the weight of high-voltage transmission lines, and caused the wires to be broken or pull down the iron tower. The invention is an on-line and off-line sling designed for a power transmission line deicing device designed by the inventor, which can go over porcelain bottles. Due to the harsh conditions of removing ice on transmission lines in the field, this equipment has to be sent to the iron rail full of ice an...
