Problems solved by technology
[0002] On large transformers and reactors, corrugated pipes are generally used for long-distance pipeline connections. Due to the influence of foundation flatness, product manufacturing and installation deviations, etc., bellows often produce stretching or bending deformation, and the deformation is too large. Assembly leading to bellows damage
In addition, large-diameter corrugated pipes have a large corrugated compression force and are difficult to compress. Once there is a large deviation in the pipeline, it is easy to hinder the installation work

The invention relates to a novel corrugated pipe stretching, limiting and pressing method and a auxiliary structure, and belongs to the technical field of transformer equipment. The auxiliary structure is characterized in that a first flange plate (1) is fixedly connected with one ends of pull rods (2), a second flange plate (4) is provided with holes (8) of which the diameters are greater than that of the pull rods, and the second flange plate (4) is movably connected with the other ends of the pull rods through the holes; multiple pull rods are arranged on the outer circumferences of the first flange plate and the second flange plate, the pull rods are divided into a baffle plate structural pull rods and nut structural pull rods, and the two types of pull rods are arranged at intervals;baffle plates (5) are arranged at the ends, located on the second flange plate, of the baffle plate structural pull rods; nuts (7) are arranged at the ends, located on second flange plate, of the nutstructural pull rods; the centers of the first and second flange plates and a corrugated pipe (3) are provided with a central shaft (9), and the central shaft is press tightly or stretched through central nuts (6). According to the auxiliary structure, by arranging the pull rods on the outer circumferences of the flanges, the maximum stretching length of the corrugated pipe (3) can be limited, andthe pull rods can be used for pressing the corrugated pipe to make on-the-spot installation convenient.

technical field [0001] The invention relates to a novel bellows stretching limit and compression method and an auxiliary structure, belonging to the technical field of transformer equipment. Background technique [0002] On large transformers and reactors, corrugated pipes are generally used for long-distance pipeline connections. Due to the influence of foundation flatness, product manufacturing and installation deviations, etc., bellows often produce stretching or bending deformation, and the deformation is too large. The assembly causes damage to the bellows. In addition, large-diameter corrugated pipes have a large corrugated compression force and are difficult to compress. Once there is a large deviation in the pipeline, it is easy to hinder the installation work. Contents of the invention [0003] The purpose of the present invention is to provide a new type of bellows stretching limit and compression method and auxiliary structure. A pull rod is set on the outer ri...
