Description

TECHNICAL FIELD

[0001] The present application relates to the field of GIS carrying, in particular to a modular carrying device for GIS installation. BACKGROUND

[0002] In high-voltage electrical equipment, gas insulated switchgear (GIS) occupies an important position, is a key core equipment for power transmission and transformation, has the advantages of compact structure, small occupation space, no influence from external environment, high operation reliability, long maintenance period, etc., since its appearance in the 1960s, the use of GIS has been increasing, but there are many problems in the installation of GIS at present.

[0003] 1. High labor intensity and safety risk

[0004] During the installation of GIS, due to the lack of automatic installation equipment indoors, the components are usually hoisted to the ground by a truck crane, and then slowly slid to the installation place by using a crowbar, because the equipment is large in size and heavy in weight, the labor intensity is high, and there is a safety risk.

[0005] 2. Existing installation method affects product installation quality

[0006] In the case of sufficient space, the installation mainly depends on the lifting of the lifting appliance, and the manual moving and alignment through the pulling rope or the bar. This manual operation method may cause bruising or damage to the GIS components.

[0007] 3. Problems of existing installation equipment

[0008] In recent years, some companies have developed devices for GIS installation, and the current fully automatic installation equipment has high use and maintenance costs, and the operating personnel must be professionally trained, which increases the human input. SUMMARY

[0009] The purpose of the embodiment of the present application is to provide a modular carrying device for GIS installation, which combines a hydraulic elevator and a modular guide rail, has small running frictional resistance, can be disassembled, can be operated by one person, greatly improves the work efficiency, reduces the labor intensity, and can meet the construction requirements of different substations.

[0010] To achieve the above purpose, the present application provides the following technical solutions:

[0011] This application provides a modular transport device for GIS installation, including a GIS tank assembly, a lateral telescopic assembly, a slide rail assembly, a hydraulic lifting jack assembly, and a lifting ring. The hydraulic lifting jack assembly is located above the slide rail assembly and is used to transport the GIS tank. The entire device is hydraulically driven. The hydraulic lifting jack assembly and the lifting ring are connected by a connecting plate to lift the GIS tank assembly as a whole. The lateral telescopic assembly is equipped with a slide rail assembly, and the track spacing of the lateral telescopic assembly can be adjusted to suit different GIS assemblies.

[0012] The lateral telescopic assembly includes a lateral support plate and a threaded telescopic rod. A fixing block is welded to the lateral support plate, and an insertion shaft is inserted into the hole on the lateral support plate for connecting and installing the two slide rails of the slide rail assembly. The lateral support plate increases the force-bearing area and maintains the stability of the equipment. The threaded telescopic rod adjusts the distance between the two slide rails of the slide rail assembly.

[0013] The slide rail assembly includes inclined rails, straight rails, and curved rails. The GIS tank assembly moves from the inclined rails to the straight rails for transporting the GIS assembly. When a turn is required, a curved rail is installed to meet the turning requirements. The straight rails of the slide rail assembly are installed in the mounting grooves provided on the transverse support plate.

[0014] The hydraulic lifting jack assembly includes a jack section and universal steel wheels. The jack section consists of a pin, a connecting plate, a fixing nut, a lifting component, and a lifting device. The connecting plate clamps the lifting component with a pin, and the other end is clamped to the lifting ring with a fixing nut. The lifting device provides power to lift and lower the entire GIS equipment. Several sets can be installed depending on the situation.

[0015] The universal steel wheel is installed in the track groove of the slide rail assembly and runs along the track groove.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] This invention develops a modular installation device. Modular guide rails are laid indoors. The device uses a claw-type hydraulic lift. The front claw of the lift is fixed to one end of a connecting plate by a pin, and the other end of the connecting plate is fixed to a lifting eye hole. The claw-type hydraulic lift with a lifting mechanism moves the load-bearing components, ensuring smooth transportation and preventing damage to the GIS components.

[0018] The device integrates a hydraulic lift with modular guide rails, resulting in low operating friction resistance. The device is detachable and can be operated by a single person, significantly improving work efficiency and reducing labor intensity. It can meet the construction requirements of different substations.

[0019] The entire device uses low-priced hydraulic claw jacks, and the slide rails are all made of industrial aluminum alloy, which is low-cost, lightweight, easy to disassemble, and highly practical. Attached Figure Description
