Assembly type indoor GIS (Gas Insulated Switchgear) transportation and installation equipment and using method thereof

Abstract

The invention discloses assembly type indoor GIS (Gas Insulated Switchgear) transportation and installation equipment and a using method thereof. The assembly type indoor GIS transportation and installation equipment comprises bearing mechanisms for hoisting a GIS, lifting mechanisms for supporting the bearing mechanisms, travelling trolleys for driving the lifting mechanisms to operate, and traveling mechanisms used in conjunction with the traveling trolleys, wherein the two ends of the supporting mechanism are fixed to the traveling trolleys through the lifting mechanisms to form a portal frame; and the traveling trolleys are arranged on the traveling mechanisms. The assembly type indoor GIS transportation and installation equipment can not only realize the rapid installation and maintenance of the GIS, but also can be adaptively adjusted according to different GIS installation and use environments, can be recycled multiple times and has strong universality through the modular designof the travelling mechanisms, the travelling trolleys, the lifting mechanisms and the bearing mechanisms; in addition, the telescopic boom technology is applied to the lifting mechanisms; and boom pins and cylinder pins are arranged simultaneously and symmetrically on the lifting mechanism, so that the stress condition of a telescopic boom is improved very well, and the stability of the GIS transportation process is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of substations, and relates to a GIS transportation and installation equipment, in particular to a modular assembly type GIS transportation and installation equipment for indoor high-rises and a use method thereof. Background technique [0002] GIS (Gas Insulated Switchgear) gas insulated switchgear is mainly used in the fields of high voltage, extra high voltage and ultra high voltage, and is an important equipment in the power system. Since GIS equipment is a primary equipment composed of several blocks, it has high requirements for positioning accuracy and docking technology, and the weight of GIS equipment is large, so the quality of transportation and installation of GIS equipment seriously affects its operation status and service life.

AI Technical Summary

Problems solved by technology

Since GIS equipment is a primary equipment composed of several blocks, it has high requirements for positioning accuracy and docking technology, and the weight of GIS equipment is very large, so the transportation and installation quality of GIS equipment seriously affects its operation status and service life

In addition, some GIS equipment is placed indoors, and the GIS room often has limited space and cannot use large hoisting and transporting equipment, resulting in slow installation progress and low efficiency of GIS equipment

Moreover, in order to meet the indoor use requirements of GIS equipment, it is necessary to lay multiple wire ducts or add embedded parts on the indoor floor, which greatly increases the difficulty of GIS equipment transportation.

[0003] According to the feedback of a large number of substation construction projects, the use of GIS indoor cranes for transportation generally has low efficiency, high failure rate, low precision, constraints of construction power configuration, and loads that cannot meet the installation and transportation of large GIS equipment. security risks and other issues

[0004] At present, foreign GIS indoor transportation and installation equipment includes transportation equipment combined with driving and hydraulic carts, air cushion handling equipment, small tank handling, etc., but the above equipment has the disadvantages of high maintenance costs and high requirements for the site, so it lacks versatility and cannot be used. Universal use

Domestic GIS indoor transportation and installation equipment are mainly roller bars, cranes or other lifting equipment; although the operating cost is relatively low, there are the following problems: (1) Low efficiency, generally requires multiple transfers such as unloading, hoisting, and transmission, which not only increases (2) There are unpredictable safety hazards. Since the position of GIS equipment needs to be constantly adjusted during transportation, it may cause unpredictable damage to the equipment and even affect its later operation. (3) When the rollers are used for transportation, because the diameters of the rollers laid under the equipment are not completely consistent, or the indoor ground is uneven, the GIS equipment will vibrate when it moves, which will easily cause the internal components of the GIS equipment to be displaced. Affect the safe operation of GIS equipment

[0005] In addition, according to the different voltage levels of GIS equipment, the size and weight of the intervals are not the same, and it is impractical to design transportation and installation equipment for different intervals
