DETAILED DESCRIPTION OF EMBODIMENT (S) OF INVENTION
As shown in fig. 1, in a specific embodiment, the present invention provides a frog assembly 100 comprising: point rail 106 and wing rail 102, fork and heel rail 104, first spacer iron 110, second spacer iron 114, backing plate 118, and fastening assembly 120. The frog assembly 100 designed by the invention improves the overall stability by connecting the point rail 106, the wing rail 102 and the fork and heel rail 104 together by the first connecting part 108 and fixing the point rail, the wing rail and the fork and heel rail on the base plate 118. The wing rail 102 adopts the NM400 steel rail, so that the use of alloy steel materials is effectively reduced, the alloy steel is applied to the parts easy to wear, and the material cost is reduced. The alloy steel point rail 106 and the wing rail 102 can be machined by adopting a forming cutter, so that the machining difficulty is reduced, and the machining efficiency is improved. Compared with the integral alloy steel frog, the frog assembly 100 provided by the invention has the advantages that the grinding space is not limited any more due to the separated welding, the weld joint grinding efficiency is greatly improved, the welding part is reduced, and the installation difficulty is reduced.
Specifically, the center rail 106 is forged from alloy steel and then machined. The fork and heel rail 104 is made of a common channel rail.
Further, the present invention provides a switch structure 200, comprising the frog assembly 100 of any of the above embodiments, wherein the wing rail 102 of the frog assembly 100 is welded to the rail of the switch structure 200 by flash welding, specifically, the welding surface of the wing rail 102 is processed into the shape of the end surface of the tram rail, and is welded to the rail by flash welding, and the welding seam is ground after welding to ensure the smoothness of welding.
Further, both ends of the weld of the wing rail 102 and the rail are reinforced with a third spacer 206 and a reinforcing plate, respectively. Specifically, a third spacer 206 is disposed between first and second wing rails 1022, 1024 and at the connection of first and second rails 202, 204 and wing rail 102; one end of the third spacer 206 is connected to the first wing rail 1022 and the second wing rail 1024 through the fourth connecting portion 208; the other end of the third spacer 206 is connected to the first rail 202 and the second rail 204 by a fifth connection 210.
Further, the top surface of the third spacer 206 is located on the same plane as the track, so that the shared right of the turnout structure 200 and the road surface is guaranteed, a pit formed on the road surface due to an overlarge gap between the first wing rail 1022 and the second wing rail 1024 is avoided, and the safety is improved.
Further, a first reinforcing plate 212 is disposed at a connection position of the first wing rail 1022 and the first rail 202, one end of the first reinforcing plate 212 is connected to the first wing rail 1022 through a fourth connecting portion 208, and the other end of the first reinforcing plate 212 is connected to the first rail 202 through a fifth connecting portion 210; a second reinforcing plate 214 is disposed at a junction of the second wing rail 1024 and the second rail 204, one end of the second reinforcing plate 214 is connected to the second wing rail 1024 by a fourth connecting portion 208, and the other end of the second reinforcing plate 214 is connected to the second rail 204 by a fifth connecting portion 210. Thereby achieving a strengthening of the connection between the wing rail 102 and the rail by the third spacer iron 206 and the stiffening plate.
According to the frog assembly 100 provided by the invention, the wing rail 102, the point rail 106 and the fork heel rail 104 are designed into the detachable structure, and the wing rail, the point rail and the fork heel rail are connected and fastened through the first connecting part 108, so that compared with an integral alloy steel frog, the casting and processing difficulty of the frog assembly 100 is reduced while the performance of the frog is ensured, the manufacturing cost of the frog assembly 100 is further reduced, and the detachable structural design can further facilitate the transportation process of the frog assembly 100 and reduce the installation difficulty. By adopting the alloy steel rail as the point rail 106 and the NM400 rail as the wing rail 102, the performance of the frog assembly 100 is ensured while the detachable structure of the frog assembly 100 is realized, and compared with the alloy steel frog in the prior art, the alloy steel is reduced, and the material cost of the frog assembly 100 is reduced.
