　　Mining DC630-5-12 symmetrical switch supplier

　　Symmetrical switch manufacturer, mining symmetrical switch, symmetrical switch model representation, DC630-5-12 symmetrical switch

　　Everyone knows that the standardization and serialization of symmetrical turnouts are very important for the design, construction, and production of coal mines or other mines. Tai'an Yucheng has strict manufacturing and acceptance standards, and the rail type, gauge, and turning angle of symmetrical turnouts are serialized, which is suitable for the diverse usage situations in China's coal mining industry. We are capable of making turnouts. If you need them, please contact us quickly. Yucheng will definitely not disappoint your trust!

　　1、 DC630-5-1 symmetrical switch related knowledge sharing:

　　After multiple practices, it has been proven that there is a gap between the narrow ends of the two wing rails and the tip of the frog when the wheels pass through the frog, which is the harmful space of the turnout. When the wheels pass through this area, they may derail due to walking in the wrong frog groove. The purpose of setting up guardrails is precisely to force the direction of wheel movement. However, this harmful space limits the speed at which trains can pass through turnouts, which is very detrimental to the operation of high-speed trains.

　　The fundamental way to solve the problem of hazardous spaces in turnouts is, of course, to eliminate hazardous spaces. Since ordinary turnouts cannot be made, it is necessary to develop special turnouts - movable point rail turnouts.

　　The main feature of the movable track is that the frog track can move with a plate. When we want to open a track in a certain direction, the frog point rail of the movable point rail is closely attached to the wing rail in the same direction as the opening direction, and separated from the other wing rail. In this way, the harmful space of ordinary turnouts no longer exists. Practice has proven that eliminating the harmful space of turnouts results in smoother driving and lower speed limits when passing through turnouts, making it particularly suitable for routes with large traffic volumes and the need for high-speed trains.

　　2、 Knowledge supplement:

　　Symmetrical switch types: The narrow gauge railway of the Ministry of Coal Industry has three gauges: 600, 762, and 900mm; 15. 22, 30, 38, 43, KG/m five rail types; There are seven types of turnouts, including single turnout, symmetrical turnout, crossover turnout, and a small number of crossover turnouts, symmetrical combination turnouts, diamond crossover turnouts, and four track nested turnouts. There are eight types of turnouts according to different types, including 2 #, 3 #, 4 #, 5 #, 6 #, 7 #, 8 #, 10 #, and 11 standard curve radius turnouts of 4, 6, 9, 12, 15, 20, 25, 30, 40, 50, and 70m are equipped according to different frog numbers.

　　3、 Conclusion sharing:

　　Each turnout has its own code, such as No.9 turnout, No.12 turnout, No.18 turnout, etc. Using large turnouts is advantageous for train operation. However, things always have their two sides. The larger the number of turnouts and the longer the turnouts, the higher the cost and the larger the land occupation. Therefore, the number of turnouts to be used should be tailored to local conditions and vary depending on the line, and cannot be generalized.
