The specific embodiment
Below in conjunction with accompanying drawing, by describing a better specific embodiment in detail, the utility model is further elaborated.
As shown in Figure 1, a kind of cylindrical shell anti-deformation vertical lifting device is used for lifting by crane cylindrical shell 1, comprises: hanging beam body 2; Fixedly shore piece 3, it is fixedly connected on hanging beam body 1 one ends; The adjustable piece 4 of shoring, it is movably connected in hanging beam body 1 other end; A pair of shelf component, it is separately positioned on the two ends of hanging beam body 2, and is positioned at and fixedly shores piece 3, adjustable piece 4 tops of shoring.The adjustable piece 4 of shoring is provided with two waist shaped hole 41(referring to Fig. 2).This device also comprises two bolts 42, and it is located in respectively on each waist shaped hole 41; Adjustable bolt 6, it shores piece 4 and hanging beam body 2 links to each other with adjustable, so that the adjustable piece 4 of shoring moves radially along cylindrical shell 1.
Describedly fixedly shore piece 3 and the adjustable piece 4 shored is provided with respectively boss 7 with cylindrical shell 1 coupling end place, the plane of boss 7 and circumference through make after the machinework its with cylindrical shell on groove more identical, more steady safety during lifting.
Described boss 7 is suitable with cylindrical shell 1 groove.
Each described shelf component comprises:
A pair of fixed frame 51, it is installed in respectively hanging beam body 2 outer side edges;
Correspondence is inserted in the shelf 52 in each fixed frame 51.
When the utility model uses, first hanging beam body 2 is hung in the steam generator cylindrical shell 1.The piece 3 of fixedly shoring on the hanging beam body 2 is tightened fixingly by bolt and hanging beam body 2, the adjustable piece 4 of shoring is regulated adjustable piece 4 sway of shoring by adjustable bolt 6, and piece 3 and adjustable length of shoring distance L size between the piece 4 are fixedly shored in control.After the distance L adjustment was suitable, then hanging beam body 2 was just put into cylindrical shell smoothly, by shelf 51 hanging beam body 2 steadily is shelved on cylindrical shell 1 end face.Adjustable shore piece 4 and hanging beam body 2 to fix and position method as follows: first shelf 52 is inserted in the fixed frames 51, then fix with the threaded pin nail piece, in order to reduce floating of shelf 52, the front end of pin is that 19.8 millimeters axle and 20 millimeters hole on the shelf match, the gap only has 0.2, the rear end be M24 screw thread directly and framework tighten.Then adjustable bolt 6 is regulated the adjustable piece 4 of shoring, adjust the radial position of hanging beam body 2 in cylindrical shell 1, until fixedly shore piece 3, the adjustable boss of shoring piece 47 fits like a glove with the internal diameter at cylindrical shell 1 groove place, then two bolts 42 in the waist shaped hole 41 are tightened.After spacing the confining in the position of hanging beam body 2 in cylindrical shell, outside lifting hanging beam winches to corresponding docking location by hanging beam body 2 along continuous straight runs with cylindrical shell 1, confirms two joint cylindrical shells 1 on same line of centers (referring to Fig. 3), finally welds.
