Single Turnout Brief Introduction
Turnout is the one track branches into two or more tracks, so that rolling stock transferred by the one line to another line of the basic settings. Frog turnout numbers used to represent numbers, working on both sides of the heart side of the fork angle, called the frog angle, angle cotangent frog frog called numbers. Commonly divided into single turnout , turnout symmetry, Double Slip Switches and cross-degree line. Turnout is a special track equipment, not only affect the safe operation of trains, but life is also shorter than other devices, on-site maintenance and repair workload. China's most popular single turnout, the main line is straight, lateral line from the main line to the left or right fork out, also known as the left and right turnout turnout, the number of all types accounted for over 90% of the total turnout.
Single Turnout Features
Single turnout is one of the common rail parts, movable point crossing a single turnout, is the frog individual components can be moved to any evidence when the train too lean continuous trajectories, eliminating fixed single turnout frog the presence of hazardous space and cancel guard rail,Meanwhile single turnout frog geometry on the profile can also be greatly reduced under the smooth, thereby significantly reducing single turnout frog parts of wheel-rail interaction, improve operation and stability, prolong the life of frog,.Long-term operating practice shows that the service life of rail frog tempted to same cast high manganese steel frog 6 ~ 9 times, maintenance workload by 40%, greatly reducing the rolling stock by the impact, improved the single open rail allows for speed and comfort.
