Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1-3, the present invention provides an embodiment: an inward-inclined forged flange comprises a flange plate 1, an upper tower barrel 12 and a lower tower barrel 13, wherein a convex neck 2 is arranged at the outer edge of the upper surface of the flange plate 1, a plurality of bolt holes 3 are formed in the surface of the flange plate 1, an inward-inclined slope is arranged on the lower plane of the flange plate 1, connecting shafts 4 are fixedly connected to two sides of each bolt hole 3, opposite ends of the two connecting shafts 4 are rotatably connected with connecting pieces 6 through short shafts 5, a through pipe 7 is fixedly connected between the opposite sides of the two connecting pieces 6, a through groove 8 is formed between the top and the bottom of the through pipe 7, the inward-inclined slope of the inward-inclined forged flange is changed into a plane due to the outward turning phenomenon in the welding process, so that the bolt holes 3 can incline, even if the two connecting shafts 4 in the bolt holes 3 incline, at the moment, because the connecting bolts 9 penetrate through the two through pipes 7, thereby make siphunculus 7 take place to rotate through connecting piece 6 and minor axis 5 and connecting axle 4 to guarantee that two siphunculus 7 keep on same straight line, prevent that bolt hole 3 from taking place the slope and die connecting bolt 9 card in the inside of bolt hole 3.
Connecting bolts 9 are arranged inside the through grooves 8, one end of each connecting bolt 9 is connected with a connecting nut 10 in a threaded mode, the connecting bolts 9 sequentially penetrate through the through pipes 7 in the two inward-inclined forged flange bolt holes 3 and extend to the outer portion of the inward-inclined forged flange, the connecting nuts 10 are sleeved, and the two inward-inclined forged flanges are fixed together by screwing the connecting nuts 10.
The top and the bottom on the surface of the connecting bolt 9 are both sleeved with gaskets 11, and the gaskets 11 are provided with two gaskets for reducing friction, preventing leakage, isolating, preventing loosening or dispersing pressure.
The top and the bottom on siphunculus 7 surface all set up to the arc, and the top and the bottom on siphunculus 7 surface all set up to the arc to improve the convenience that connecting bolt 9 got into, and reduce the friction with bolt hole 3.
The bolt holes 3 are circularly and uniformly arranged on the surface of the flange plate 1, the bolt holes 3 are provided with a plurality of bolts, and the bolt holes 3 penetrate through the flange plate 1, so that the connecting bolts 9 can penetrate through the inward-inclined forged flange.
The working principle is as follows: firstly, oppositely stacking the surfaces of two inward-inclined forged flanges provided with inward-inclined slopes together, then sleeving a gasket 11 on a connecting bolt 9, sequentially enabling the connecting bolt 9 to pass through pipes 7 in bolt holes 3 of the two inward-inclined forged flanges, extending to the outside of the inward-inclined forged flanges, sleeving a gasket 11 on the connecting bolt 9, finally sleeving a connecting nut 10, screwing the connecting nut 10 to fix the two inward-inclined forged flanges together, welding an upper forged flange with an upper tower barrel 12 of a fan tower, welding a lower forged flange with a lower tower barrel 13 of the fan tower, and enabling the inward-inclined slopes of the inward-inclined forged flanges to be turned into planes by the outward turning phenomenon in the welding process, so that the bolt holes 3 are likely to incline even if two connecting shafts 4 in the bolt holes 3 incline, at the moment, because the connecting bolt 9 penetrates through the two through pipes 7, so that the through pipes 7 and the connecting shaft 4 rotate through the connecting piece 6 and the short shaft 5, and the two through pipes 7 are kept on the same straight line.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
