Abstract

The invention relates to a fastener assembly provided with bolts and suitable for a heavy-load railway with the axle load being 35-40 tons. The fastener assembly is composed of the T-shaped bolts, nuts, flat washers, elastic strips, insulated gauge blocks, an under-rail base plate and pre-embedded iron pedestals. The pre-embedded iron pedestals are pre-embedded on a concrete foundation, and the T-shaped bolts are mounted on the pre-embedded iron pedestals for fastening the elastic strips; the insulated gauge blocks are arranged between a steel rail and the pre-embedded iron pedestals, and meanwhile, the left and right positions of the steel rail are adjusted by replacing the insulated gauge blocks with the different thicknesses; and then the under-rail base plate is arranged under the rail, and elasticity of the fastener system is provided. The fastener assembly provided with the bolts is suitable for the heavy-load railway with the axle load being 35-40 tons. A gauge baffle is omitted, and the design of dovetail grooves in the pre-embedded iron pedestals is optimized. According to the fastener assembly provided with the bolts, all the functions of an existing fastener assembly with bolts can be achieved, the number of parts is small, the structure is simple, and maintenance and repairing operation is convenient.

Description

technical field [0001] The invention relates to a rail fastening system, in particular to a fastening assembly with bolts suitable for heavy-duty railways with an axle load of 35-40 tons. Background technique [0002] Heavy-duty railway transportation has been widely valued by railways all over the world because of its large capacity, high efficiency and low transportation costs. For example, a large number of heavy-duty trains are operated on heavy-duty railways in the United States, Canada, Brazil, Australia, and South Africa. Passenger transportation is used in Europe. Heavy-duty trains have also begun to run on the main mixed passenger and freight lines. As one of the important components of the track structure, fasteners play an important role in maintaining the gauge and enhancing the stability of the track structure. [0003] Fasteners with bolts are widely welcomed because they have the ability to adjust the height and position of the rail, and the buckle pressure c...
