Further, the hose is snakeskin hose.
Further, the main pipe side is identical or different the distance between per adjacent two branch pipe.
Further, the main pipe is set to the equipment middle part that thermal power plant need to disintegrate or overhaul.
Further, since it is considered that cooling tube is hose, bolt is being carried out to need to keep hose in cooling procedure
Position, guarantee cool down bolt, and the cooling tube is supported by bracket.
Further, the bracket is rigid trestle, and bracket, which is arranged, is used to support the card slot of cooling tube, the size of card slot with
The part side of cooling tube matches, and the bracket of each hose is structure as a whole part or separate structure part, frame bottom are set to
Ground, alternatively, bracket is the vertical bar with card slot, as long as it is exactly feasible for being able to achieve to the support of cooling tube.
Compared with prior art, the utility model has the beneficial effects that
(1) the utility model structure is simple, can be used for multiple times for a long time, maintenance cost is low.
(2) the utility model can carry out multiple bolts while cooling by the setting of multiple branch pipes, effectively improve work
