Description

Technical Field

[0001] The utility model relates to the technical field of maintenance hoisting, and more specifically, to a hoisting device for the disassembly and overhaul of GIS equipment. Background Art

[0002] GIS is a gas-insulated metal-enclosed switchgear, which is a form of high-voltage distribution device. According to the installation external environment, GIS has two types, outdoor type and indoor type. The structures of these two types are basically the same, except that the outdoor type has additional anti-climate measures. When it is damaged, it needs to be disassembled, overhauled and maintained. However, due to the weight of the GIS equipment, it needs to be hoisted by hoisting equipment. For example, a hoisting structure for the disassembly and overhaul of GIS equipment disclosed in the prior art publication number (CN206767452U) includes a detachable support frame, a hoisting mechanism and a weight monitoring device. This hoisting structure can adjust the height and width according to different requirements of space and live parts; the hoisting structure can move when lifting heavy objects, which is convenient for the disassembly and assembly of GIS equipment; the hoisting structure is detachable and easy to transport, flexible and convenient; at the same time, the hoisting mechanism can finely adjust the lifting and lowering of the hoisted object, solving the problem that large cranes and other hoisting machinery cannot operate finely during the operation process. The support frame includes a cross beam and two vertical beams. The two vertical beams are fixedly arranged at both ends of the cross beam. The vertical beams and the cross beam are respectively composed of multiple I-beams. The multiple I-beams are connected by bolts, realizing that the height and width of the structure can be adjusted and can be adjusted according to the operation space and live parts.

[0003] When the above device is used, it can reduce the demand for manpower and shorten the overhaul time; the cross beam and longitudinal beam of the support frame are composed of multiple detachable I-beams, realizing that the height and width of the hoisting structure can be adjusted. However, when it is moved and disassembled and overhauled, the GIS equipment is prone to looseness, thus affecting the stability of its disassembly and overhaul and the convenience of workers' operation.
