Title:
TRAMCAR TURNOUT SWITCH STRUCTURE
Document Type and Number:
WIPO Patent Application WO/2022/267254
Kind Code:
A1
Abstract:
A tramcar turnout switch structure, mainly composed of a manganese steel base (1), and a straight stock rail (2) and a curved switch rail (3) fixed inside the manganese steel base (1). The manganese steel base (1) comprises a first connecting section (101) located at the head, a second connecting section (102) located at the tail, and a base section (103) located between the first connecting section (101) and the second connecting section (102). The base (1) is integrally cast with high manganese steel, and has a short production cycle, a small processing amount, and a great advantage in the production cost. Since the base (1) is integrally cast, after the straight stock rail (2) and the curved switch rail (3) are assembled, the overall stability of the structure is good, and the assembly precision is higher. The straight stock rail (2) and the curved switch rail (3) can be made of alloy steel plates, and the hardness thereof is generally 380 HBW or more, which can well meet the requirements of a user for wear resistance, and reduce the maintenance workload.
