Description
Technical field
The utility model relates to a kind of antidetonation bar assembling auxiliary mould that is used for bundle of steam generator.
Background technology
Bundle of steam generator is a kind of " giving ring " design, it is made up of the U type pipe that is installed in 4,640 690 alloy materials on the tube sheet usually, and is square arrangement, and the external diameter of every U type pipe is Φ 19.05mm, the pore spacing that U type pipe is installed on the tube sheet is 27mm, and its total heat exchange area is 5631m
2, tube bank is 10604.5mm apart from tube sheet secondary side height.
Generally, tube bundle assembly is supported by 8 blocks of tube supports plates, 1 flow distribution baffle and 3 layers of U type antidetonation bar.Yet because the steam generator volume is big, object is heavy, precision is high, and the gap is very little between antidetonation bar and adjacent U type pipe, and adopt welding manner to fix between antidetonation bar and retaining ring, make the antidetonation bar produce very big distortion and contraction after welding, this has brought very large difficulty to clearance control between antidetonation bar and U type pipe.For this reason, urgently in assembling and welding process, taked some can reduce the means of being out of shape and shrinking between antidetonation bar and U type pipe now.
The utility model content
In order to solve the problem that above-mentioned prior art exists, the utility model aims to provide the assembly tooling of a kind of antidetonation bar, effectively finishing the assembling of antidetonation bar, and reduces distortion and contraction between antidetonation bar and U type pipe.
A kind of antidetonation bar assembling auxiliary mould that is used for bundle of steam generator described in the utility model, described bundle of steam generator comprises some U type pipes of arranging by matrix form, and be respectively equipped with an antidetonation bar that is the U type between the adjacent U type pipe of per two row, described auxiliary mould comprises the clamping device that is arranged on described adjacent two antidetonation bars and the pitch piece between their opposite ends and is used for described adjacent two antidetonation bars of clamping and the pitch piece between them.
At the above-mentioned antidetonation bar assembling auxiliary mould that is used for bundle of steam generator, described clamping device is a hexahedron, this hexahedral bottom surface is provided with a groove that is used to set described adjacent two antidetonation bars and the pitch piece between them, its end face is provided with one section downward-sloping wedge surface, this wedge surface is provided with one and is used to assemble the screw of an adjustment screw, and this screw and horizontal plane are at angle, so that the bottom of described adjustment screw is stretched out described groove one sidewall and withstood described antidetonation bar.
Owing to adopted above-mentioned technical solution, the utility model is by being provided with the pitch piece between adjacent antidetonation bar, and fix position between them by clamping device, thereby avoid after the antidetonation bar and the welding process of retaining ring in the distortion and the phenomenon of shrinking between caused antidetonation bar and U type pipe, guarantee that matching requirements are satisfied in the gap between antidetonation bar and the U type pipe.The utility model can guarantee specification requirement, has advantages such as easy to operate, that manufacturing is simple, processing cost is lower, reusable again.
Description of drawings
Fig. 1 is a kind of scheme of installation that is used for the antidetonation bar assembling auxiliary mould pitch piece of bundle of steam generator;
Fig. 2 is a kind of scheme of installation that is used for the antidetonation bar assembling auxiliary mould clamping device of bundle of steam generator.
The specific embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
See also Fig. 1, Fig. 2, bundle of steam generator comprises some U type pipes of arranging by matrix form 1, and be respectively equipped with an antidetonation bar 2 that is the U type between the adjacent U type pipe 1 of per two row, the two ends of every antidetonation bar 2 are respectively equipped with an end cap 21 that is used for retaining ring 3 welding.
The utility model, it is a kind of antidetonation bar assembling auxiliary mould that is used for bundle of steam generator, comprise the clamping device 5 that is arranged on adjacent two antidetonation bars 2 and the pitch piece 4 between their opposite ends and is used for two adjacent antidetonation bars 2 of clamping and the pitch piece 4 between them, wherein:
Clamping device 5 is a hexahedron, this hexahedral bottom surface is provided with a groove 51 that is used to set adjacent two antidetonation bars 2 and the pitch piece 4 between them, its end face is provided with one section downward-sloping wedge surface, this wedge surface is provided with one and is used to assemble the screw 52 of an adjustment screw 6, and this screw 52 and horizontal plane be α (angle [alpha] is generally 20 degree) at angle, so that the bottom of adjustment screw 6 stretches out groove 51 1 sidewalls and withstands antidetonation bar 2, thus make antidetonation bar 2 and pitch piece 4 by clamping in groove 51.
The size design of pitch piece 4 should be according to the actual size of bundle of steam generator (pitch piece 4 of the present utility model have possessed the needs of 8 kinds of specifications with the U type pipe 1 that adapts to different size in actual design), and to guarantee tolerance at manufacture view, in addition, should as much as possible pitch piece 4 be settled near U type pipes 1 according to actual conditions, and directly get final product applying the tight power of increment (direction of this tight power of rising in value and pitch piece 4 are on same straight line) on the antidetonation bar 2 by clamping device 5.
Because for the every antidetonation bar 2 that will tighten and weld, the final position of itself and retaining ring 3 need be by the installation diagram location of antidetonation bar 2, be that matching requirements should be satisfied in gap between antidetonation bar 2 and the U type pipe 1, therefore, gap between antidetonation bar 2 and the U type pipe 1 can be adjusted to by the utility model and to require the position, and guarantee the degree of accuracy of this position, thereby the situation of avoiding antidetonation bar 2 that the welding because of antidetonation bar 2 and retaining ring 3 causes and 1 distortion of U type pipe and shrinking; In addition, can be after every antidetonation bar 2 and retaining ring 3 are tightened and welded by the U type pipe 1 of the most close pitch piece 4 being pushed be positioned at gently to the antidetonation bar 2 of one side, and measure the mode of U type pipe 1 and the gap x between the antidetonation bar 2 of its opposite side with clearance gauge, check the rigging position of antidetonation bar 2 whether to reach requirement.
Below embodiment has been described in detail the utility model in conjunction with the accompanying drawings, and those skilled in the art can make the many variations example to the utility model according to the above description.Thereby some details among the embodiment should not constitute qualification of the present utility model, and the scope that the utility model will define with appended claims is as protection domain of the present utility model.
