Double-rocker-arm landing holding pole safety power control system

Abstract

The invention discloses a double-rocker-arm landing holding pole safety power control system which comprises supporting frames; an electric hydraulic lifting rod is fixed between the supporting frames; an electric rotating device is fixed at the upper end of the electric hydraulic lifting rod; a rotary vertical arm is fixed on the electric rotating device; a first rocker arm is hinged to one sideof the lower end of the rotary vertical arm; a second rocker arm is hinged to the other side of the lower end of the rotary vertical arm; pulley blocks, around which a steel wire rope passes, are fixed at the upper end of the rotary vertical arm, the other end of the first rocker arm, the other end of the second rocker arm and the lower ends of the supporting frames respectively; and the other endof the steel wire rope is connected with a corresponding winch after penetrating through the pulley block at the upper end of the rotary vertical arm and the pulley blocks at the lower ends of the support frames. The double-rocker-arm landing holding pole safety power control system has the beneficial effects that centralized control is on one operation table, so that disorder of a field configuration is eliminated, the multi-coordination command difficulty of occupying personnel is large, the risk of manual retraction and pay-off of the hoisting steel wire rope is large, the safety construction difficulty is large, and the like.

Description

technical field [0001] The invention relates to the field of hoisting systems, in particular to a safety power control system for double-rocker landing poles. Background technique [0002] As my country enters the era of UHV power grids, UHV power transmission projects have been intensively started in recent years. An important part of this is the construction of UHV iron towers. At present, motor-driven winches are basically used as power, and the tradition of manpower retracting and lifting steel wire ropes is used. Means, the number of people occupied is large, the synergy is poor, and the efficacy is low. The present invention is composed of centralized control operations such as double luffing, double hoisting, including boom hoisting and horizontal rotation, so that 8 to 12 people need to operate a double rocker arm hoisting system instead of one person. In terms of safe centralized control operation, equipment storage and lifting of wire ropes, overload protection, el...
