Embodiment
Below our problem of the upper and lower flange dislocation that in building course, occurs with the 9FA diffuser solve the practical application of specifically setting forth dislocation adjusting device of the present utility model.
As shown in Figures 2 and 3, Fig. 2 utilizes the dislocation adjusting device of the present utility model schematic diagram that the lower flange dislocation is adjusted on to the 9FA diffuser, and Fig. 3 is the viewgraph of cross-section that the dislocation adjusting device is regulated upper and lower flange among Fig. 2.As seen from the figure, have two large diameter adpting flanges on the 9FA diffuser, be connected with lower flange by two upper flanges.Because diameter is too big, distortion often when connecting, occurs, thereby cause connecting hole corresponding on the upper and lower flange dislocation to occur, make fastening bolt to penetrate and fix.Be all alignment straight of connecting hole 41,42,43 and 44 of the upper flange among Fig. 2, need take certain means to align back the connection.
When using dislocation adjusting device of the present utility model, at above-mentioned situation, often need paired use, promptly use the dislocation adjusting device to come the hole and install to connect by twos.In fact, dislocation appears between the upper and lower flange, two kinds of situations nothing more than, a kind of situation is that the edge of upper flange is outwards outstanding than the edge of lower flange, a kind of situation is that the edge of lower flange is outwards outstanding than the edge of upper flange, all can take adjusting device of the present utility model to adjust under two kinds of situations.
I am that example is set forth adjustment process upper flange 4 to occur outwards more outstanding than lower flange 3.As shown in Figure 2, outer outstanding on the upper flange 4, the connecting hole on the upper flange is also correspondingly outwards outstanding than the connecting hole on the lower flange, has shown four holes among the figure, and numbering is respectively first connecting hole, 41, the second connecting holes 42, the 3rd connecting hole 43 and the 4th connecting hole 44.
When adjusting butt joint, need earlier second connecting hole 42 to be connected and fixed, two adjusting devices 1 are put into the position of first connecting hole 41 and the 3rd connecting hole 43 respectively, specifically be that front end with the alignment pin 14 of adjusting device 1 penetrates in the connecting hole corresponding on the lower flange 3 and carries out, tighten second then and regulate bolt 13, adjusting device 1 is fixed on the lower flange 3.
, after fixedly finishing on the lower flange 3, on it two first regulate bolts 12 and correspond respectively to first connecting hole 41 and the 3rd connecting hole 43 at two adjusting devices 1, with second connecting hole 42 as hole to be installed.
Then; tighten first on two adjusting devices 1 respectively and regulate bolt 12; make its edge generation extruding radially to upper flange 4; during this time; in order to prevent that flange from damaging; regulate bolt 12 first and placed protection pad 5 with the flange contact position, the front is regulated bolt 13 second and has also been placed protection pad 2 with the flange contact position.Along with extruding force increases gradually, dislocation between the upper and lower flange is eliminated gradually, need check whether corresponding connecting hole aligns on second connecting hole 41 and the lower flange 3 on the upper flange 4, as if having alignd, then with fastening bolt upper flange 4 is connected with lower flange 3 this moment.
Then, respectively two adjusting devices 1 are moved in its contiguous connecting hole, as move to the 4th connecting hole 44 positions from the 3rd connecting hole 43, with the 3rd connecting hole 43 as hole to be connected, only adjusting device 1 of needs was screwed in the 4th connecting hole 44 and regulated this moment, finish because there has been second connecting hole 42 to connect, so do not need to be screwed in second connecting hole 42 with another one adjusting device 1 again.But another one adjusting device 1 can move on to the other connecting hole adjacent with first connecting hole 41 and realize simultaneously upper flange 4 is connected by first connecting hole 41 with lower flange 3.
By that analogy, finish each connecting hole alignment between whole upper flange 4 and the lower flange 3 gradually, and be connected and fixed with fastening bolt.Finish the dislocation adjustment of whole upper flange 4 and lower flange 3 at last and accurately be connected.
Through the installation of tens of 9FA diffusers, this instrument is simple and reliable, and is easy to operate, and operating efficiency is more than being doubled with crow bar, and is very laborsaving, is subjected to assembling master worker's welcome.
