Embodiment 1

[0027] A tramway switch switch structure, such as Figure 6 As shown, it is mainly composed of a manganese steel base 1 and a straight basic rail 2 and a curved point rail 3 fixed inside the manganese steel base. The manganese steel base 1 includes a first connecting section 101 at the head, The second connecting segment 102 at the tail and the base segment 103 between the first connecting segment and the second connecting segment.

[0028] The base is integrally cast with high manganese steel, which has a short production cycle and a small amount of processing, which has great advantages in production cost. Since the base is integrally cast, after assembling the straight basic rail and the curved point rail, the overall stability of the structure is very good, and the assembly accuracy is also higher. Straight basic rails and curved point rails can be made of alloy steel plates, and their hardness is usually above 380HBW, which can well meet the user's requirements for wear ...

Abstract

The invention provides a tramcar turnout switch structure which is mainly composed of a manganese steel base, a straight stock rail and a curved switch rail, the straight stock rail and the curved switch rail are fixed in the manganese steel base, and the manganese steel base comprises a first connection section located at the head, a second connection section located at the tail and a base section located between the first connection section and the second connection section. The base is integrally cast by high manganese steel, so that the process production period is short, the processing amount is small, and the production cost is greatly reduced. Due to the fact that the base is integrally cast, after the straight stock rail and the curved switch rail are assembled, the overall stability of the structure is good, and the assembling precision is higher. The straight stock rail and the curved point rail can be made of alloy steel plates, the hardness of the straight stock rail and the curved point rail is generally 380 HBW or above, the requirement of the user for wear resistance can be well met, and the maintenance workload is reduced.

Description

technical field [0001] The invention relates to the field of turnout switch technology, in particular to a pedestal type tramway switch switch structure. Background technique [0002] In order to alleviate traffic pressure, more and more cities have begun to vigorously develop urban rail transit, such as trams, subways, and elevated light rails. Modern trams usually use grooved rails, such as figure 1 shown. The grooved rail also has the function of the wheel guard rail, which is conducive to ensuring the safety of small radius curves, effectively ensuring the passage space of the wheel rim in the shared right-of-way section, and is conducive to the pavement and protection of the pavement material inside the rail. [0003] The turnout is one of the three weak links of the track in the traditional wheel-rail transportation system. The layout of the tram line is flexible and the radius of the curve is small. Therefore, it is required to have a small number of turnouts, a ...
