Description
Technical field
The present invention relates to lifting appliance, particularly the vertical lifting appliance of a kind of cylindrical shell anti-deformation.
Background technology
In the nuclear power manufacturing process, because the steam generator volume is big, object is heavy, precision is high, and the diameter of cylindrical shell is big, and wall thickness is easy to generate distortion.What general cylindrical shell adopted when docking is horizontal state, because the weight of cylindrical shell self is between 20 ~ 40 tons, the deadweight of the holder power of steel rope and cylindrical shell produces squeezing action during lifting, make cylindrical shell produce elliptical shape easily, and when being placed on the turning rolls welding after the heating, out of roundness when cylindrical shell is docked with cylindrical shell is bigger, has influenced assembling and the welding quality of steam generator cylindrical shell.
By having taked the way of vertical lifting and butt joint, the distortion and the welding that have reduced cylindrical shell are shunk in actual production.In the frock design; actv. utilizes the cassette groove on the cylindrical shell; because the groove overhang is very little; have only 10 millimeter (about cylinder internal diameter 3600mm), hanging beam is skidded off when lifting, install lifting beam with special folder roof construction form; two joints or more cylindrical shell; groove by on the lifting cylindrical shell of the folder roof construction safety on the lifting beam plays a very good protection to the cylindrical shell anti-deformation, has guaranteed the accuracy of cylindrical shell assembling.The nuclear power manufacturing technology is further improved.
Summary of the invention
The purpose of this invention is to provide the vertical lifting appliance of a kind of cylindrical shell anti-deformation, this device is easy to operate, makes simply, safe and reliable, and repeated usage can satisfy the cylindrical shell size of all kinds of size variation, has both guaranteed technical requirements, and tooling cost is lower.
In order to realize above purpose, the present invention is achieved by the following technical solutions:
The vertical lifting appliance of a kind of cylindrical shell anti-deformation is used for lifting by crane cylindrical shell, is characterized in, comprises:
The hanging beam body;
Fixedly shore piece, it is fixedly connected on hanging beam body one end;
The adjustable piece of shoring, it is movably connected in the hanging beam body other end;
A pair of shelf component, it is separately positioned on the two ends of hanging beam body, and is positioned at and fixedly shores piece, the adjustable piece top of shoring.
The described adjustable piece of shoring is provided with some waist shaped holes.
This device also comprises some bolts, and it is located in respectively on each waist shaped hole.
This device also comprises adjustable bolt, and it shores piece and the hanging beam body links to each other with adjustable, makes adjustablely to shore piece and move radially along cylindrical shell.
Describedly fixedly shore piece and adjustablely shore piece and cylindrical shell coupling end place is provided with boss respectively.
Described boss and cylindrical shell groove are suitable.
Each described shelf component comprises:
A pair of fixed frame, it is installed in hanging beam body outer side edges respectively;
Correspondence is inserted in the shelf in each fixed frame.
The present invention compared with prior art has the following advantages:
The present invention is easy to operate, makes simply, safe and reliable, and repeated usage can satisfy the cylindrical shell size of all kinds of size variation, has both guaranteed technical requirements, and tooling cost is lower.

Fig. 2 for the vertical lifting appliance of a kind of cylindrical shell anti-deformation of the present invention the adjustable block structure scheme drawing of shoring;
Scheme drawing when Fig. 3 docks for cylindrical shell.
The specific embodiment
Below in conjunction with accompanying drawing, by describing a preferable specific embodiment in detail, the present invention is further elaborated.
As shown in Figure 1, the vertical lifting appliance of a kind of cylindrical shell anti-deformation 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, makes the adjustable piece 4 of shoring move radially along cylindrical shell 1.
Describedly fixedly shore piece 3 and the adjustable piece 4 shored is provided with boss 7 respectively 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, steady more 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 hanging beam body 2 outer side edges respectively;
Correspondence is inserted in the shelf 52 in each fixed frame 51.
When the present invention uses, earlier 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: earlier shelf 52 is inserted in the fixed frames 51, fix with threaded pin spare then, in order to reduce floating of shelf 52, the pin front end be 19.8 millimeters the axle with shelf on 20 millimeters hole match, the gap has only 0.2, the rear end be M24 screw thread directly and framework tighten.Adjustable bolt 6 is regulated the adjustable piece 4 of shoring then, 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.
When removing the position of hanging beam body 2 in cylindrical shell 1, transfer loose adjustable bolt 6 to get final product.
In sum, the vertical lifting appliance of a kind of cylindrical shell anti-deformation of the present invention, this device is easy to operate, makes simply, safe and reliable, and repeated usage can satisfy the cylindrical shell size of all kinds of size variation, has both guaranteed technical requirements, and tooling cost is lower.
