Abstract

The invention relates to a sliding type gantry crane with roller and purpose thereof for hauling GIS equipment, and the sliding type gantry crane with roller comprises a main beam portion, a control portion and a supporting portion, and the main beam portion further comprises a main beam, which is arranged in the middle of the gantry crane horizontally; support beams at the double ends are vertically arranged on the double ends of the main beam for supporting the main beam; a slide rail at the top is fixed and arranged below the main beam; an electric slide dolly is installed and hanged below the top slide rail and slides along the top slide rail; a dolly running gear is matched with the top slide rail for assisting the electric slide dolly to slide along the top slide rail; an electric chain hoist is arranged below the electric slide dolly for moving the hoist equipment up and down; a supporting portion comprises a roller and a fix apparatus for fixing the roller to the bottom of the supporting portion, and the whole crane can be flexibly moved and conveniently dismounted.

Description

technical field [0001] The invention specifically relates to a sliding type gantry crane with rollers and its application, which belongs to the field of installation and maintenance of GIS equipment. Background technique [0002] In the power industry, GIS is the abbreviation of "Gas Insulated Switchgear", which refers to all equipment in a substation except transformers, including circuit breakers, disconnectors, grounding switches, voltage transformers, current transformers, Lightning arresters, busbars, cable terminals, inlet and outlet bushings, etc., are organically combined into a whole through optimized design, which is the switch station we often see, also called high-voltage power distribution equipment. [0003] GIS is high-voltage electrical equipment with high operational reliability, less maintenance workload, and long maintenance cycle. Its failure rate is only 20% to 40% of conventional equipment, but GIS also has its inherent shortcomings. Due to the leakage ...
