Description
Technical field
The present invention relates to boom hoisting, particularly a kind of cylindrical shell anti-deformation vertical lifting device.
Background technology
In nuclear power manufacture process, because steam generator volume is large, object heavy, precision is high, and the diameter of cylindrical shell is large, and wall thickness is thin, easily produces distortion.What adopt during general cylindrical shell docking is horizontal state, because the weight of cylindrical shell self is between 20 ~ 40 tons, during lifting, the towing force of steel wire rope and the deadweight of cylindrical shell produce squeezing action, cylindrical shell is easily made to produce elliptical shape, and after being placed on when turning rolls welds heating, ovality when cylindrical shell is docked with cylindrical shell is larger, have impact on assembling and the welding quality of steam generator cylindrical shell.
By taking vertical lifting and the way of docking in actual production, the distortion and the welding that reduce cylindrical shell are shunk.In Fixture Design; effectively utilize the cassette groove on cylindrical shell; because groove overhang is very little; only have 10 millimeter (cylinder internal diameter about 3600mm), likely making hanging beam skid off when lifting by crane, installing lifting beam by special folder roof construction form; the cylindrical shell of two joints or more; by the groove on the lifting cylindrical shell of the folder roof construction safety on lifting beam, cylindrical shell anti-deformation is played a very good protection, ensure that the accuracy that cylindrical shell assembles.Nuclear power manufacturing technology is improved further.
Summary of the invention
The object of this invention is to provide a kind of cylindrical shell anti-deformation vertical lifting device, this device is easy to operate, and manufacture simple, safe and reliable, reuse, can meet the cylindrical shell size of all kinds of size variation, both ensured technical requirement, processing cost is lower.
In order to realize above object, the present invention is achieved by the following technical solutions:
A kind of cylindrical shell anti-deformation vertical lifting device, is used for lifting by crane cylindrical shell, is characterized in, comprises:
Hanging beam body;
Fixedly shore block, it is fixedly connected on hanging beam body one end;
Adjustablely shore block, it is movably connected in the hanging beam body other end;
A pair shelf component, it is separately positioned on the two ends of hanging beam body, and is positioned at and fixedly shores block, adjustablely shore block top.
Described adjustable block of shoring is provided with some mounting holes.
This device also comprises some bolts, and it is located on each mounting hole respectively.
This device also comprises adjustable bolt, and it shores block with adjustable and hanging beam body is connected, and makes adjustablely to shore block and move radially along cylindrical shell.
Described fixedly shore block and adjustablely shore block and cylindrical shell link place is respectively equipped with boss.
Described boss and cylindrical shell groove suitable.
Each described shelf component comprises:
A pair fixed frame, it is arranged on 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, and manufacture simple, safe and reliable, reuse, can meet the cylindrical shell size of all kinds of size variation, both ensured technical requirement, processing cost is lower.

Fig. 2 be a kind of cylindrical shell of the present invention anti-deformation vertical lifting device adjustablely shore block structure schematic diagram;
Schematic diagram when Fig. 3 is cylindrical shell docking.
Detailed description of the invention
Below in conjunction with accompanying drawing, by describing a preferably specific embodiment in detail, the present invention 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 block 3, it is fixedly connected on hanging beam body 1 one end; Adjustablely shore block 4, it is movably connected in hanging beam body 1 other end; A pair shelf component, it is separately positioned on the two ends of hanging beam body 2, and is positioned at and fixedly shores block 3, adjustablely shore block 4 top.Adjustable block 4 of shoring is provided with two mounting hole 41(see Fig. 2).This device also comprises two bolts 42, and it is located on each mounting hole 41 respectively; Adjustable bolt 6, it shores block 4 with adjustable and hanging beam body 2 is connected, and adjustable block 4 of shoring is moved radially along cylindrical shell 1.
Described fixedly shore block 3 and adjustable block 4 of shoring is respectively equipped with boss 7 with cylindrical shell 1 link place, the plane of boss 7 and circumference make groove on its and cylindrical shell more identical after machined, more steady safety during lifting.
Described boss 7 is suitable with cylindrical shell 1 groove.
Each described shelf component comprises:
A pair fixed frame 51, it is arranged on 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, first hanging beam body 2 is hung in steam generator cylindrical shell 1.Block 3 of fixedly shoring on hanging beam body 2 is tightened fixing by bolt and hanging beam body 2, and adjustable block 4 of shoring regulates adjustable block 4 of shoring to move left and right by adjustable bolt 6, controls fixedly to shore block 3 and adjustable length of shoring the spacing L size of block 4.After distance L adjustment is suitable, then hanging beam body 2 just puts into cylindrical shell smoothly, by shelf 51, hanging beam body 2 is steadily shelved on cylindrical shell 1 end face.Adjustable shore block 4 and hanging beam body 2 to fix and position method as follows: first shelf 52 is inserted in fixed frame 51, then fix by threaded nail piece, in order to reduce floating of shelf 52, the front end of pin is that the hole of 20 millimeters on the axle of 19.8 millimeters and shelf matches, gap only has 0.2, rear end be M24 screw thread directly and framework tighten.Then adjustable bolt 6 regulates and adjustablely shores block 4, adjust the radial position of hanging beam body 2 in cylindrical shell 1, until fixedly shore block 3, the adjustable boss 7 shoring block 4 fits like a glove with the internal diameter at cylindrical shell 1 groove place, then the bolt of two in mounting hole 41 42 is tightened.The position of hanging beam body 2 in cylindrical shell is spacing confine after, cylindrical shell 1 is winched to corresponding docking location by hanging beam body 2 by outside lifting hanging beam in the horizontal direction, confirms two joint cylindrical shells 1 on same center line (see Fig. 3), finally carries out welding.
When removing the position of hanging beam body 2 in cylindrical shell 1, adjust loose adjustable bolt 6.
In sum, a kind of cylindrical shell anti-deformation of the present invention vertical lifting device, this device is easy to operate, and manufacture simple, safe and reliable, reuse, can meet the cylindrical shell size of all kinds of size variation, both ensured technical requirement, processing cost is lower.
Although content of the present invention has done detailed introduction by above preferred embodiment, will be appreciated that above-mentioned description should not be considered to limitation of the present invention.After those skilled in the art have read foregoing, for multiple amendment of the present invention and substitute will be all apparent.Therefore, protection scope of the present invention should be limited to the appended claims.
