Abstract
The utility model relates to a steel rail connector which comprises a rail sheet, clamping plates, adhesive forming grooves and fastening bolts, wherein, the rail sheet is arranged on the joint part of the end head of a common steel rail and the end head of a high manganese steel frog, the adhesive forming grooves are respectively arranged on two side surfaces of the end head of the common steel rail and the end head of the high manganese steel frog, the clamping plates are arranged on the outside of the forming grooves, and the adhesive forming grooves and the clamping plates are fixedly connected with the end head of the common steel rail and the end head of the high manganese steel frog through the fastening bolts and nuts. Thereby, rail gaps are effectively eliminated, and the service life of the frogs is extended. In addition, the utility model also has the advantages of simple operation, low cost and easy application.
Description
The utility model relates to a kind of rail linkage, particularly a kind ofly is used to improve train speed and the common rail of overlength gapless track that operates steadily and the linkage of high manganese steel frog.
Usually when laying the overlength gapless track, its common rail is connected with high manganese steel frog, and having only by common clamping plate 12 (as shown in Figure 9) has seam to connect, and affects the application of overlength gapless track.
At present, states such as Austria, France are when the casting manganese steel frog, in one section middle transition section of railway frog two ends weldering connection, this transition rail piece mainly is the austenite structure of steel, have the characteristic that can also can weld connection with high manganese steel frog weldering connection with the rail of common material, this rail gap just can weld connection with exothermic welding when laying the overlength gapless track.But this technical costs is too high, performance difficulty.
The purpose of this utility model is will provide a kind of can overcome above-mentioned defective, effectively eliminates rail gap, simple to operate, a kind of rail linkage that bonding strength is high, easy to implement.
The purpose of this utility model is achieved in that a kind of rail linkage, comprising rail sheet, clamping plate, bonding adhesive grooving and fastening bolt, above-mentioned rail sheet is arranged on the joint of described common steel rail ends and high manganese steel frog termination, described common steel rail ends and two sides, high manganese steel frog termination are respectively equipped with the bonding adhesive grooving, grooving is provided with clamping plate outward, by means of fastening bolt and nut with bonding adhesive grooving, clamping plate and common steel rail ends and high manganese steel frog termination Joint.
The advantage of the rail linkage that the utility model proposes is, overcome the problem that high manganese steel frog and common rail can not directly weld, eliminated rail gap effectively, reduced impact force, prolong the application life of railway frog, reduced maintenance load, and simple to operate, cost is low, and is easy to implement.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Below in conjunction with accompanying drawing, the concrete structure that the utility model proposes is further described with regard to its most preferred embodiment.
As shown in drawings, above-mentioned rail linkage 4, comprising rail sheet 7, clamping plate 2, bonding adhesive grooving 8 and fastening bolt 5, above-mentioned rail sheet 7 is arranged on the joint of described common steel rail ends 1 and high manganese steel frog termination 6, described common steel rail ends 1 and 6 two sides, high manganese steel frog termination are respectively equipped with bonding adhesive grooving 8, the outer clamping plate 2 that are provided with of grooving 8, by means of fastening bolt 5 and nut 3 with bonding adhesive grooving 8, clamping plate 2 and common steel rail ends 1 and high manganese steel frog termination 6 Joints.
Shown in Fig. 6,7, the cross section of described bonding adhesive grooving 8 is the Contraband font, the web of the rail of its external surface and common steel rail ends 1 and high manganese steel frog termination 6 is complementary, the bottom surface 9 of its inner surface and clamping plate 2 is complementary, and the center line of above-mentioned bonding adhesive grooving 8 is provided with the through hole 10 that passes for bolt 5 more than.
Shown in Fig. 4,5, the center line of described clamping plate 2 is provided with the through hole 11 that passes for bolt 5 more than, its bottom surface 9 is a plane that is complementary with the inner surface of above-mentioned bonding adhesive grooving 8, in use guaranteeing that maximum contact area is arranged, thereby improves the intensity that is connected.
As shown in Figure 8, described rail sheet 7 is identical with the rail profile shape, and the end face of rail sheet 7 exceeds and is connected 0.5～1 millimeter of rail level, so in use, by the backing of wheel, make the mechanical performance of high manganese steel frog and common rail a changeover portion occur, thereby increase the service life.
Bonding adhesive grooving 8 in the above-mentioned rail linkage can be formed by multiple material casting such as epoxy resin and curing compound, when mounted, common steel rail ends 1 that carried out processing of rust removing with special tool and 6 pairs of high manganese steel frog terminations are connected, contact position in clamping plate 2 and common steel rail ends 1 and high manganese steel frog termination 6 is provided with bonding adhesive grooving 8, tighten fastening bolt 5 and nut 3 then, make it become an integral body through heat tracing.
