Detailed description of the invention
Hereinafter, the protection canopy for turbine stay ring assembly welding of the present utility model is described with reference to the accompanying drawings in detail.
Fig. 1 shows the top view of protection canopy under application state for turbine stay ring assembly welding according to the utility model exemplary embodiment, and Fig. 2 shows the elevation of the protection canopy for turbine stay ring assembly welding according to the utility model exemplary embodiment.
As depicted in figs. 1 and 2, according to exemplary embodiment of the present utility model, the described protection canopy for turbine stay ring assembly welding comprises four side refractory slabs 1 and four side refractory slabs 1 surround the protective zone of protection canopy.Further, because this protective zone is the space of four sides relative closure around, the assembly welding of turbine stay ring can be carried out thus in the protective zone of this protection canopy.
Particularly, protection canopy is made up of frame 2 and the canopy face 3 be coated on frame 2 outer surface, and protection canopy can be made thus to have higher intensity and have the effect of opposing seal, heat-insulation and heat-preservation, fire protection flame retarding simultaneously.Further, protection canopy has at least one fan mandoor 4, pass in and out to facilitate welder personnel.
According to the utility model, frame 2 is the frame structure combined by square steel column 22 and square steel crossbeam 21, and to ensure the convenience of frame intensity and assembling, its concrete combining structure can be as shown in Figure 2.Wherein, the size of frame 2 and protection canopy can be determined according to seat ring size, and such as, the length of protection canopy can be 3 ~ 6m, width is 3 ~ 6m, be highly 3 ~ 6m, but the utility model is not limited thereto.
