Problems solved by technology

Since the GIS bushing is in a vertical state when passing through the frame, the boom of the crane needs to be in a higher state. In order to protect the insulator string from being damaged by the collision of the boom, it is necessary to consider installing the GIS outlet sleeve for the crane when designing the height of the frame. Although it provides enough space for activities, the design height is higher, but the increase in the height of the frame will increase the construction cost of the project and increase the investment.

Abstract

The invention discloses a GIS lead-out bushing hoisting method used for hoisting a GIS lead-out bushing to the inner side of a framework. Hoisting equipment includes a main crane and an auxiliary crane, the main crane is a 100-ton crane, and the auxiliary crane is a 25-ton crane. Hoisting includes the steps that the GIS lead-out bushing is transversely arranged on the outer side of the framework, the main crane hoists the head portion of the GIS lead-out bushing, the auxiliary crane hoists the tail portion of the GIS lead-out bushing, the two cranes hoist the GIS lead-out bushing and horizontally lift the GIS lead-out bushing by 3-5 m, the main crane and the auxiliary crane enable lifting arms to pass through the position below the framework and extend to the inner side of the framework at the same speed, the height of the lifting arm of the auxiliary crane is kept unchanged, the lifting arm of the main crane is lifted until the GIS lead-out bushing is lifted to be vertical, and the auxiliary crane is moved away; the lifting arm of the main crane descends so that the GIS lead-out bushing can be placed on a bushing base, and hoisting is finished. By means of the method, the height of the GIS lead-out bushing is reduced, hoisting safety is guaranteed, the height of the framework is reduced, and construction cost is reduced.

Description

technical field [0001] The invention relates to a casing hoisting method, in particular to a method for hoisting a GIS outlet casing to the inner side of a frame. Background technique [0002] The frame includes frame support columns on both sides, frame beams connecting the upper ends of the two frame support columns, and insulator strings suspended on the frame beams. The side of the frame where GIS equipment and other electrical equipment are installed is the inner side, and the other side is the outer side; GIS The outlet bushing is an important part used in GIS equipment. When the GIS outlet bushing is installed on the bushing base, the upward end is the head, and the end connected to the bushing base is the tail. The GIS equipment is set inside the frame. Due to the Due to the limitation of space inside the frame, when hoisting the GIS outlet casing, it is necessary to use a crane to hoist the GIS outlet casing into the inside of the frame outside the frame. When hois...
