A hoisting device, installation method, and electrified hoisting method for an iron tower of a transmission line

Abstract

The invention relates to a lifting device of an electric transmission line iron tower. The lifting device comprises an electric transmission line iron tower, the electric transmission line iron towercomprises a tower head and a tower body, a longitudinal telescopic main material fixator set is fixed to the two sides of the tower body, the telescopic main material fixator set comprises two telescopic main material fixators in left-right symmetry, a cage-shaped framework is formed by the telescopic main material fixators and horizontal fixator auxiliary parts, the two ends of one of the fixatorauxiliary parts are connected to the upper ends of the two telescopic main material fixators correspondingly, and the two ends of the other fixator auxiliary part are connected with the lower ends ofthe two telescopic main material fixators correspondingly. The invention further relates to the lifting device, a mounting method and an electric lifting method. According to the lifting device and the mounting method of the electric transmission line iron tower, and the electric lifting method, difficult in construction area coordination can be effectively avoided, uninterruptible construction can also be conducted on lines, stable operation of the power grid can be guaranteed, and the purpose that the height of a pole tower can be risen by electrifying on the original position of the pole tower can be achieved.

Description

technical field [0001] The invention relates to the technical field of transmission line operation of a power grid system, and relates to a method for increasing the distance between a wire and the ground when a transmission line is live, and in particular to a lifting device, an installation method and a live raising method for an iron tower of a transmission line. Background technique [0002] At present, due to changes in the external environment such as offline construction, construction, and tree planting, the transmission lines of the power grid system have insufficient safety distances between conductors and crossing objects, threatening the safe and stable operation of the line. The usual method is to increase the inspection density, stop the construction work in advance in time, and prevent the distance from the conductors from being too short, but most of the violations cannot be stopped in time due to various reasons. The only way to overhaul is to replace the tow...

Problems solved by technology

[0002] At present, due to changes in the external environment such as offline construction, construction, and tree planting, the transmission lines of the power grid system have insufficient safety distances between conductors and crossing objects, threatening the safe and stable operation of the line.

The usual method is to increase the inspection density, stop the construction work in time in advance, and prevent the distance from the conductors from being too short, but most cases cannot stop violations in time due to various reasons

The only way to overhaul is to use the method of power failure to replace the pole tower to increase the height of the conductor. This method involves land occupation coordination, which is very difficult and often leads to stagnation of construction into the site and affects the construction progress.

The power outage plan still needs strict approval, and the problem cannot be solved quickly
