BOLTED FASTENER ASSEMBLY SUITABLE FOR HEAVY HAUL RAILWAY WITH AXLE LOAD OF 35-40 TONS

摘要

Provided is a bolted fastener assembly suitable for a heavy haul railway with an axle load of 35-40 tons. The bolted fastener assembly is composed of a T-shaped bolt (3), a nut (5), a flat washer (6), an elastic strip (4), an insulating gauge block (7), a railway subplate (2) and a pre-embedded iron base (1). The pre-embedded iron base (1) is embedded in advance in a concrete foundation, the T-shaped bolt (3) is mounted on the pre-embedded iron base (1) to fasten the elastic strip (4), the insulating gauge block (7) is provided between a steel rail and the pre-embedded iron base (1), and meanwhile left and right positions of the steel rail are adjusted by changing the insulating gauge blocks (7) of different thicknesses, and then the railway subplate (2) is provided under the railway to provide elasticity in a fastener system. Through the structure, all functions of an existing bolted fastener can be achieved, fewer parts are provided, the structure is simple, and maintenance operation is convenient.
