Abstract
The invention discloses a lifting method for a basket barrel for nuclear power which can be most insusceptible to size of the basket barrel without welding. A plurality of supporting circles are mounted in the core barrel. Each supporting circle is formed by a plurality of arc support members connected end to end. A lifting hole used for penetration of a lifting steel wire is reserved on each support member. Lateral edge, near the inner wall of the basket barrel, of each support member extends radially along the basket barrel. A plurality of bolts are connected to each extended portion in a threaded manner respectively. The bottom of each bolt is abutted to the inner wall of the basket barrel. An end face at the end with margin of the core barrel is connected with the supporting circles at the end with margin of the basket barrel through a plurality of connection blocks. Lifting can be performed after the supporting circles and the connection blocks are mounted, penetrating the lifting steel wire through the lifting hole and fixing the supporting circles. By the method, the basket barrel can be lifted while the size of the basket barrel is guaranteed, and assembly is convenient and rapid.
Description
Technical field
The present invention relates to a kind of nuclear power hoisting method of cradle cylinder body.
Background technology
At present, the fossil energy reserves of the earth are limited and atmosphere polluted, and the renewable sources of energy are because receiving all its degree of utilization deficiencies that limits, and the whole world all is faced with problems such as energy scarcity and environmental pollution, and nuclear power can be alleviated these problems as safety, its development of the energy efficient, cleaning.Therefore, the development prospect of nuclear power is very wide.
The manufacturing of Shandong, the Huaneng Group Shidao Bay nuclear power plant HTGR nuclear station demonstration project metal stack inner member that my company has accepted, the material of this equipment barrel is 12Cr2Mo1R, barrel diameter 5400mm, circularity requires 6mm, cylindricity requires 8mm, and the circularity requirement of the conventional pressure container of specification of the same race is to be not more than 25mm, and visible requirement is quite high.Because the particularity of material and the high request of size, if during to assembling, still adopt the lifting method (as Fig. 1) of traditional welding hanger in the cylindrical shell group, can bring a series of problem.
The first, the welding of this type of material (12Cr2Mo1R) needs in weld preheating, the welding process strict control interlayer temperature, the postheating hydrogen that disappears, and operates very loaded down with trivial details, weldquality is difficult to guarantee, occur cooling crack easily, have a strong impact on lifting safety, weld a hanger and often want for a long time consuming time;
The second, because welding hanger 2 can cause the local deformation of cradle cylinder body 1, be difficult to guarantee circularity and the cylindricity of this product requirement;
The 3rd, during lifting, 1 four of cradle cylinder body are stressed, and cradle cylinder body 1 circumferential discontinuity influences product size;
The 4th, after finishing, product must remove hanger 2, and the polishing work capacity is quite big.
Summary of the invention
Technical matters to be solved by this invention is: a kind of hoisting method that the nuclear power that just can not influence the cradle cylinder body size is to greatest extent used cradle cylinder body that do not need to weld is provided.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of nuclear power hoisting method of cradle cylinder body, some installations hold round frock in cradle cylinder body earlier, holding round frock is joined end to end to surround by some arc strut members and forms, offer the lifting eye that passes for hoisting wirerope on each strut member, strut member extends axially along cradle cylinder body respectively near the side of cradle cylinder body inwall, several bolts have been threaded respectively on the extending part, the bottom of bolt offsets with the cradle cylinder body inwall respectively, the end end face that cradle cylinder body leaves surplus links to each other by several contiguous blocks with close holding round between the frock of cradle cylinder body surplus one end, install according to the method described above and hold round frock and contiguous block, hoisting wirerope is passed to lift by crane after lifting eye and rigid staybolt sired results are adorned then.
Leave a uniform circle tapped bore on the end end face of surplus in cradle cylinder body, the tapped bore degree of depth is no more than the surplus size, one end of contiguous block is fixed on cradle cylinder body by screw and leaves on the end end face of surplus, and the other end is loaded onto by the cooperation rigid staybolt sired results of bolt of rear end plate and nut.
The invention has the beneficial effects as follows: utilize said method under the requirement that guarantees the cylindrical shell size, to lift by crane cradle cylinder body, easy to assembly, quick.Not be used in welding and removal hanger on the cradle cylinder body, reduced unnecessary algorithm, improved production efficiency.
Description of drawings
Fig. 1 is cradle cylinder body lifting constructional drawing in the background technology;
Fig. 2 is cradle cylinder body lifting constructional drawing among the present invention;
Fig. 3 is the constructional drawing when among Fig. 2 contiguous block not being installed.
Among the figure: 1, cradle cylinder body, 2, hanger, 3, hold round frock, 4, strut member, 5, lifting eye, 6, bolt, 7, contiguous block, 8, tapped bore, 9, screw, 10, bolt of rear end plate.
The specific embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present invention in detail.
As shown in Figure 2, the nuclear power of the present invention hoisting method of cradle cylinder body, some frocks 3 that hold round are installed in cradle cylinder body 1 earlier, holding round frock 3 is joined end to end to surround by some arc strut members 4 and forms, offer the lifting eye 5 that passes for hoisting wirerope on each strut member 4, strut member 4 extends axially along cradle cylinder body 1 respectively near the side of cradle cylinder body 1 inwall, several bolts 6 have been threaded respectively on the extending part, the bottom of bolt 6 offsets with cradle cylinder body 1 inwall respectively, the end end face that cradle cylinder body 1 leaves surplus links to each other by several contiguous blocks 7 with close holding round between the frock 3 of cradle cylinder body 1 surplus one end, install according to the method described above and hold round frock 3 and contiguous block 7, hoisting wirerope is passed to lift by crane after lifting eye 5 and rigid staybolt sired results adorn 3 then.For convenient disassembly, contiguous block 7 and hold round frock 3 and cradle cylinder body 1 between concrete annexation as follows: leave a uniform circle tapped bore 8 on the end end face of surplus in cradle cylinder body 1---shown in Figure 3, tapped bore 8 degree of depth are no more than the surplus size, one end of contiguous block 7 is fixed on cradle cylinder body 1 by screw 9 and leaves on the end end face of surplus, and the cooperation of the other end by bolt of rear end plate 10 and nut is fixed on and holds round on the frock 3.Advantage of the present invention is: utilize said method under the requirement that guarantees the cylindrical shell size, to lift by crane cradle cylinder body, and easy to assembly, quick.Not be used in welding and removal hanger on the cradle cylinder body, reduced unnecessary algorithm, improved production efficiency.
