Rail accessories can be a series of professional parts for fixing rails to the sleepers. Referred towards the track including rails, sleepers, connecting parts, track bed, anti-climbing equipment, support and vote of the railway and etc. As a whole engineering structures, track laying roadbed, plays the guiding role of the trains running directly under tremendous pressure, rolling stock certain load.Under the dynamic action of the train run, its various components should have sufficient strength and stability to ensure that according to a predetermined, safe, smooth and uninterrupted operation of the exercise.
Spikes and screws
A. Rail spike
A rail spike (also called to be a cut spike or crampon) is a nail through having an offset head that can be used to secure rails and base plates to railroad ties inside the track. Common sizes come from 9 to 10/16 inch square and ~5.5 to 6 inch way. And its main function will be always to keep the rails gauge. Additional connecting plate attachments for as strong as possible, and when connected into the rail, tie or tie plate generally not required to provide a strong vertical force, allowing the railway more freedom to move.
B. Screw spikes
A screw spike, rail screw is a large metal screws which the fixed tie plate or fixed rail. The screw spike ixed to produce a hole a sleeper. The screw spike having an increased manufacturing costs than the spike, but the advantage of experiencing a larger fixing power, approximately twice the spike, and could be combined but now spring appliance.
C. Fang bolts
Fang bolts have been used for fixing rails or chairs to sleepers. For fastening flat bottom rail the top of lip gasket may be familiar with grip the extra edge of the guide rail. They are more resistant to vibration loosening and moving rails. These kind of are considered in order to become the efficient than spikes and screws, and so might be used in positions regarding example switch (point) tie plates, and on sharp curves.
2. Rail supports
Earliest railway chairs, associated with cast iron, about 1800 to launch fixed at both ends for the cast iron rails and support, the growing system also be employed to connect adjacent tracks. Chairs have been fixed towards the sleeper using wooden spikes, screws, fang-bolts or spikes.
b. Tie plates
Tie plate, base plate or a sole plate with steel plate flange the T track and sleepers while on the tracks. The increase in the tie plate bearing areas it also have railway corrective remember. They spikes or bolts through holes on the plate fixed to the wooden love affair.
There many types of many heavy clip using the rail is bound to the substrate, a common the Pandrol Pandrol cut.
Rail per meter approximate weight in kilograms, could be divided into two associated with heavy rail and light rail.
The manufacture and take. Rail open hearth furnace, oxygen smelting carbon killed steel rolling. Its purpose is to withstand extending pressure within the rolling stock and effect load.
Manufacturing plant and importing countries. Rail currently employed in China, some domestic steel production, with regard to example Anshan Iron and Steel, Wuhan Iron and Stainlesss steel. In addition, due to fairly amount in order to import numerous physical and chemical properties required by our technical standards and relevant foreign standard alternative determine the rail and rail devices. The imported production are Japan, Germany, France, Britain, Russia, Australia additional.
Railway accessories industry investment in the development of the next 10 years, will keep a relatively dangerous. In the context for this rapid progression of the railway system in Jiangxi, this trend, the domestic creation of railway accessories will be a key process. With the process of high-speed railway construction, railway parts industry in China will achieve greater development.
