Small-radius curve concrete sleeper component

Abstract

The invention belongs to the technical field of concrete sleepers for metallurgical industrial and mining enterprises, and in particular relates to a small-radius curve concrete sleeper component comprising a small-radius curve sleeper, an upper strand steel rail and a lower strand steel rail which are arranged on the small-radius curve sleeper, and a guard rail which is arranged at the outer side of the lower strand steel rail. The small-radius curve concrete sleeper component is characterized in that two filler plate grooves with shoulders are formed in the top surface of the small-radius curve sleeper; an upper strand rail brace is arranged at the outer side of the upper strand steel rail; an upper strand filler plate is arranged at the bottom of the upper strand steel rail, and a buffer rubber mat is arranged at the bottom of the upper strand filler plate; a rail gauge adjusting block is arranged at the inner side of the upper strand steel rail; the guard rail arranged at the outer side of the lower strand steel rail is an adjustable guard rail; and a rail gauge adjusting block is arranged at the inner side of the lower strand steel rail. The small-radius curve concrete sleeper component provided by the invention adopts a concrete structure to ensure that the stability of a rail structure is stronger, the safety coefficient of locomotive running is greatly improved, meanwhile, wood materials are saved, the small-radius curve concrete sleeper component is safe and environment-friendly, and the production cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of concrete sleepers for metallurgical industrial and mining enterprises, and in particular relates to a small-radius curved concrete sleeper assembly. Background technique [0002] The sleeper is the basic material for laying the railway and one of the important components of the railway track. It is directly connected to the bottom of the rail through the iron backing plate, which can fix the position of the rail to prevent the rail from shifting when the train passes by and cause danger. The pressure generated by the train passing by is evenly distributed on the ballast, making the train run more stable. The small-radius curved sleepers of metallurgical enterprises refer to sleepers with a curve radius of less than 125 meters. The minimum curve radius of the Railway Bureau is 180 meters. However, metallurgical, mining and other industrial and mining enterprises are limited by factors such as site and terr...

Problems solved by technology

However, the use of wooden sleepers has great disadvantages. Due to the increasing axle load required for production, the material of wooden sleepers has been declining due to the national environmental protection policy, and the price is getting higher and higher. It is located in the throat of production and transportation, and cannot be modified due to environmental restrictions. It is often the busiest place for transportation. The strength of wooden sleepers is limited, and generally it can only be used for about 2 years. Therefore, railway maintenance requires a lot of materials and labor every year. Expenses, while increasing maintenance costs, the driving safety factor continues to decline

Before the Ministry of Metallurgy canceled it, it organized the research and development of small-radius concrete sleepers. At that time, the rails were directly fixed to the concrete sleepers with bolts and fasteners. After laying experiments, there were problems such as shoulder damage and lateral displacement of the rails. Due to the curve radius The smaller the size, the greater the lateral impact force. Therefore, the development of small-radius concrete sleeper components has always been a difficult technical problem for industrial and mining enterprises.
