The specific embodiment
As shown in Figure 3; The fitting device of realizing the low head displacement according to the invention; Comprise cylindrical shell 30 and turning rolls 40, said turning rolls 40 is provided with roller 41 from this cylindrical shell 30 of supported underneath, and when roller 41 rotations, can drive cylindrical shell 30 and be rotated around its axis.
Said cylindrical shell 30 is rolled and is welded by steel plate and forms.Deviation from circular from for fear of this cylindrical shell 30 is too big, causes its problem that can not on turning rolls 40, roll reposefully to take place; Therefore, need guarantee the circularity of this annular location 33 with round on said cylindrical shell 30 outer surfaces at least, thereby cylindrical shell 30 can be rotated on turning rolls 40 reposefully with annular location 33 cars of roller 41 corresponding contacts.
The size of the internal diameter of cylindrical shell 30 and the upper cover of nuclear power evaporator 10 and low head 20 is complementary.Concrete, in order to pass the hydroecium dividing plate 21 of the centre of sphere in one of the interior welds of said low head 20, low head 20 vertically is arranged in an end of cylindrical shell 30.A side opening that makes the low head 20 corresponding centre ofs sphere outwardly, the whole semicircle spheroid of opposite side places in the said cylindrical shell 30.Above-mentioned hydroecium dividing plate 21 is semi-circular plates, needs its along continuous straight runs to put during welding.Concrete welding procedure is that swing roller frame 40 makes hydroecium dividing plate 21 horizontal arrangement, and the technical staff lies prone and welds weld seam in the above one; The swing roller frame 40 afterwards, and the another side that makes hydroecium dividing plate 21 welds another road weld seam up more sidewards; And then upset, welding again, purpose is to reduce temperature distortion.
Outer surface in low head 20 open side is set with a technology ring 22, and this technology ring 22 is the peripheries that are looped around the circular cross-section at centre of sphere place, and arrange along extending radially outwardly of this circular cross-section.The end of said cylindrical shell 30 is provided with flange 32.When the semicircle spheroid of said low head 20 places in the cylindrical shell 30, said technology ring 22 will be stuck in outside the flange 32 of said cylindrical shell 30; At this moment, through connectors such as bolts with flange 32 and the 22 corresponding connections of technology ring, thereby low head 20 is fixedly connected on the cylindrical shell 30 convenient welding.
Similarly, for drier of welding on other circular cross-sections that belong to the cross section in upper cover 10 inside without opening fixedly hangs tube 11, upper cover 10 vertically is arranged in the other end of cylindrical shell 30.Upper cover 10 global approximations are the semicircle spheroid, for example are that the back rest parts is cut apart without the circular cross-section of the centre of sphere in a semicircle spheroid upper edge, and a side of its opening outwardly; At opposite side at least a portion of this semicircular spheroid is placed in the said cylindrical shell 30.Fixedly to hang tube 11 technology be that welding machine is motionless to the said drier of welding in upper cover 10, makes the workpiece rotation through turning rolls 40, and welding the track that comes out thus is a circle.
Outer surface at upper cover 10 is set with a technology ring 12; This technology ring 12 is in the position that is provided with of upper cover 10 outer surfaces, and fixedly to hang tube 11 corresponding in the circular cross-section at upper cover 10 interior welds places with said drier; Said technology ring 12 is to be looped around the peripheral of this circular cross-section and to arrange along extending radially outwardly of this circular cross-section.Said technology ring 12 is stuck in outside the flange 31 that said cylindrical shell 30 ends are provided with, at this moment, through connectors such as bolts with flange 31 and the 12 corresponding connections of technology ring, thereby upper cover 10 is fixedly connected on the cylindrical shell 30, make things convenient for and weld.
In addition, such as preceding text description ground, can make upper cover 10 and low head 20, be fixedly connected on the two ends of this cylindrical shell 30 simultaneously; Perhaps, (not shown) in other embodiments also can be only be fixedly connected upper cover 10 or low head 20 at an end of cylindrical shell 30, and makes the vacant and counterweight of the other end of cylindrical shell 30.Before a kind of advantage of implementing structure more obvious, not only save the cost expenditure of two cover positioners and large-scale clamping frock, also practiced thrift limited place.
The cylindrical shell 30 that has fixedly mounted behind upper cover 10 and/or the low head 20 is placed on the turning rolls 40; Drive the rotation of this cylindrical shell 30 by the rotation of roller 41; And then the rotation displacement that realizes going up low head; Therefore, just can substitute the function of positioner and clamping frock thereof with simple cheap turning rolls 40.
Although content of the present invention has been done detailed introduction through above-mentioned 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 modification of the present invention with to substitute all will be conspicuous.Therefore, protection scope of the present invention should be limited appended claim.
