Railway Accessories Product Introduction
Railway accessories is part of the railway line, here referring to orbit, including rail, sleeper, connecting parts, ballast bed, climbing equipment, rail brace and switch, etc. As a holistic structure, track laying on of roadbed, plays a guiding role of the train operation, direct motor vehicles and vehicle load under great pressure. Under the dynamic function of the train operation, the component part of it must have sufficient strength and stability, and ensure the train's top speed according to the regulation, safe, smooth and continuous running.
1.Railway
Railway equipment is an important equipment of railway, rail is the main symbol of railway equipment.
2.Rail Brace
Track components, in order to effectively wheel/rail lateral force resistant, installation of components on the outside of rail. Rail brace general installation in the small radius curve rail shares outside the outer edge of the rail, in order to prevent the train through the curve, the excessive lateral force caused by rail lateral displacement is too large, or even cause rail overturned. Rail brace for wooden sleeper track is more commonly. In most of the switch point rail site, also install the rail brace in basic rail lateral, in order to improve the lateral stiffness of rail, rail brace shape is very much also.
3.Anti-Creeper
Train running, often work on rail longitudinal force, made rail longitudinal mobile, sometimes even drive the sleeper move together. The longitudinal mobile, called the crawl. Crawl range in double track railway trunk line, the single direction of railway heavy car, grew up and downhill path, and stops when the range of braking.
4.Sleeper
Sleeper to support rails, and to keep the position of the rail, the rail even passed to the great pressure to track. It must have a certain flexibility and elasticity, not hard, not soft. Deformation of trains, it can be appropriate to buffer the pressure, but also after the train has to recover as soon as possible. Sleeper include wooden sleeper, concrete sleeper.
5.Connection parts
Two kinds of connecting parts connected the two rail end parts called joint connection parts; Connection between rail and sleeper parts called connection parts, fasteners. Joint connection parts rolled smoothly the wheel rail joint, and keep the two rail before and after coordination. Fasteners to rail and sleeper is an organic whole repeatedly track framework, to keep the two rail right position; Fasteners to provide enough pressure, prevent rail capsized, stop the rail longitudinal movement.
6.Ballast bed
Usually refers to under the sleeper, ballast roadbed laying on the surface of the ballast (ballast) cushion layer. Role is the main supporting sleeper, huge loads from upper sleeper, evenly distributed to the subgrade surface, greatly reducing the deformation of the subgrade. Ballast is 20 ~ 70 mm diameter small block of granite, block and block and the friction between the gap, make orbit has certain elasticity, the elastic can not only absorb shock and vibration of locomotive vehicle, make the train running smoothly, and greatly improve the locomotive vehicles, rail, sleeper components such as working conditions, prolong the service life. The elasticity of the ballast, when it is lost on the concrete sleeper load of 50 ~ 80% increase than normal state.
7.Switch
Switch is a kind of the locomotive vehicles from one track to another track circuit connection device, usually in railway stations, marshall yards laid a lot. With the switch, can give full play to the line capacity. Even the monorail, laid switch, building a is greater than the length of the train to cross it, you can split the train.
