[0018] Use process:
[0019] When using, the pot barrel backing plate 1 is contacted with barrel body outside, for increasing the supporting surface with barrel body, the support plate 2 is welded with the pot barrel backing plate 1, the support plate 2, the gusset plate 3 and the pressing plate 4 (opening transverse sliding hole 9) are mutually welded as a whole, increase the firmness of support, then the bottom plate 5 bottom plate (opening longitudinal sliding hole 10) and the pressing plate 4 are effectively connected by bolt 6, gasket 7 and nut 8, that is, the firmness of the whole support device is increased, and transverse and longitudinal expansion sliding can also be carried out, and the adjustment can also be very flexible when the pot barrel is assembled in place, that is, the thermal expansion of the boiler can be effectively released in longitudinal and transverse directions, the stress concentration caused by expansion is prevented, hidden danger for safe operation of the boiler is avoided, the boiler can be effectively supported, the boiler can be safely operated, and the pot barrel is more convenient and flexible when being assembled in place.
[0020] When the barrel body produces thermal expansion due to temperature change and other reasons during operation, the barrel body will produce size change in two directions of transverse and longitudinal directions. At this time, the pot barrel backing plate 1 connected with the pot barrel will transmit the size change to the whole structure composed of the support plate 2, the gusset plate 3 and the pressing plate 4.
[0021] The transverse sliding hole 9 on the pressing plate 4 and the longitudinal sliding hole 10 on the bottom plate 5 cooperate with each other, so that the pressing plate 4 can slide in transverse and longitudinal directions on the bottom plate 5. When the barrel body produces transverse expansion, the pressing plate 4 slides on the bottom plate 5 through the transverse sliding hole 10; when the barrel body produces longitudinal expansion, the pressing plate 4 slides on the bottom plate 5 through the longitudinal sliding hole 9.
