Problems solved by technology

The structural rigidity of the support is good, and the hoisting is simple, but it adopts the processing method of drilling and drawing holes, which will remove most of the material during processing, and this part of the material cannot be recycled, resulting in material waste, and due to The flow-induced vibration of the heat exchange tube may easily cause fretting wear between the heat exchange tube and the support

Abstract

The invention discloses a grid supporting piece. The grid supporting piece comprises an annular frame and a grid assembly arranged in the annular frame, the grid assembly comprises a plurality of highsupporting strips and a plurality of low supporting strips, the high supporting strips are provided with a plurality of first inserting grooves formed at intervals, the high supporting strips comprise first high supporting strips and second high supporting strips, a plurality of second inserting grooves are formed between every two adjacent first inserting grooves in the high supporting strips, and the low supporting strips are inserted into the second inserting grooves of the first high supporting strips and the second high supporting strips in an embedded mode. According to the grid supporting piece, the first high supporting strips and the second high supporting strips are mutually inserted and embedded, the high supporting strips and the low supporting strips are mutually inserted andembedded, a self-locking stable supporting assembly is formed, the high supporting strips and the low supporting strips are in a strip shape, the structure formed by mutual embedding of the high supporting strips and the low supporting strips has certain flexibility, uneven thermal expansion of a heat exchange pipe can be compensated, the grid supporting piece has good performance of preventing the heat exchange pipe from vibrating, so that the possibility of micro-vibration abrasion is reduced, and the grid supporting piece is applied to the technical field of steam generators.

Description

technical field [0001] The invention relates to the technical field of steam generators, in particular to a grid support. Background technique [0002] The straight pipe section of the steam generator heat exchange tube needs to be fixed by several supports, refer to figure 1 , 9 supports 100 are required in the steam generator, and the straight pipe section of the heat exchange tube passes through the through hole on the support to fix the heat exchange tube. The existing support generally adopts 30mm thick steel plate through drilling and drawing holes (Special-shaped hole, three-leaf hole or four-leaf hole) forms a porous flat plate structure. According to different steam generators, the diameter of the support is different, the diameter can reach more than 3m, and the weight can reach several tons. The structural rigidity of the support is good, and the hoisting is simple, but it adopts the processing method of drilling and drawing holes, which will remove most of the m...
