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, smal

Embodiment 1

[0061] Due to the special materials and manufacturing process of GIS equipment, the equipment itself has a relatively large weight. Generally, a single component is about 8t to 15t. When assembling in the factory, a 5T crane and a crane are generally used. However, there are the following difficulties when handling and docking at the substation site:

[0062](1) Since the GIS equipment needs to be transported horizontally, lifted vertically, and positioned accurately during the installation process, it is necessary to develop a control system for the device to realize the accurate movement of the hoisting device in the three directions of X, Y, and Z and the rotation around the Z axis Movement, so as to achieve the purpose of precise positioning of the GIS device;

[0063] (2) The floor structure of a general substation is: the first floor is the main transformer, the second floor is the GIS equipment room, and the third floor is the GIS control room. The installation space is...

Embodiment 2

[0085] During the transportation and installation process, due to the unevenness of the ground, the temporarily laid transportation guide rails are not smooth and flat, which makes the transportation equipment inevitably vibrate to a certain extent. In addition, GIS equipment is composed of different parts, and the mass and center of mass of different parts are different, resulting in an unsteady handling process; and it is impossible for GIS equipment to maintain a constant and uniform motion during the handling process, so It will increase the vibration generated. Excessive vibration will adversely affect the connection and function of components inside the GIS equipment, and will affect the stability and safety of the equipment after installation. Therefore, it is extremely important to monitor the condition during transportation.

[0086] This embodiment is further improved on the basis of the assembled indoor GIS transportation and installation equipment provided in Embo...

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. 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 i...
