Description

TECHNICAL FIELD

[0001] The present application belongs to the field of equipment installation, and particularly relates to a hoisting tool for side installation of a steel-copper slide wire and a use method. BACKGROUND

[0002] The steel-copper slide wire is a simple, convenient and efficient power supply mode specially used for power transmission of high-power mobile electric equipment, and is widely used in the metallurgy, chemical industry and mechanical manufacturing industries. There are two installation modes of the steel-copper slide wire, one is top slide and the other is side slide. In a relatively harsh dust environment, the side slide mode is usually selected, so as to avoid a large amount of dust accumulated on the contact surface of the conductive copper rail, which causes poor contact between the trolley current collector and the slide wire, and hidden troubles such as power supply failure or poor power supply, and causes the trolley to be unable to normally operate and the service life of the electric equipment to be shortened.

[0003] In the prior art, there are usually two installation modes of the side slide, one is to use a brown rope to tie a rope buckle, to pull the slide wire to the installation position, and then to manually adjust the slide wire to be vertically lateral and then to be fixed on the insulator; and the other is to use a general lifting appliance to hoist the slide wire to the installation position by the hoisting machinery, and then to manually adjust the slide wire to be vertically lateral and then to be fixed on the insulator. The above two modes both need to first adjust the slide wire to be vertically lateral at the installation position, and then to be fixed, which increases the construction operation time, is low in work efficiency, and increases the safety hazard of high-altitude operation.
