This topic is targeted at both6Number of symmetrical tunnel fork key components short life，Large maintenance and maintenance workload，Problems with high derailment risk，On the basis of absorbing the design and development of advanced technology at home and abroad，Design parameters of Dao forks、Plane layout、Steel rail structure、Dynamic simulation calculation、buckle system、Basis under the track、Converted equipment and manufacturing process conducted comprehensive research，Design formation50kg/mIron Rail6Symatic Dao fork，188bet mobile loginReview of the technical solution、Trial review、Trial trial and dynamic performance test，Results meet the design requirements，Tao fork structure has good stability。

　　The main technological innovation of the research results:One isDesign road fork plane lines suitable for transportation conditions suitable for Puchai Railway，Optimize the width method of this line -to -to -gimbing，Coordinating the connection between the Tao fork and the front and rear lines，Reduced the rate of gap change，Reinforcement of Zu fork and end structure，At the same time, the 188bet mobileinterchangeability 188bet mobileof the new Taoist fork and the existing Tao fork。The second isFor the first time, the structural type of bilateral layout of the rutor guard rail，This device effectively restricts the horizontal gesture of the rotation when passing through the rutor area，greatly improving the dynamic performance of Dao forpolation，Avoiding the derailment of the rail climbing significantly improves the niperbon life。Three isElastic clamping pressure in the inside of the basic track of the rutor area、Cancellation of the rail support structure used outside the basic track，Dual effects to 188bet mobile188bet mobile loginimprove the strength of the rail structure and alleviate the horizontal impact of the steel rail head，Further slowing the horizontal wear of the rail。Four isRu fork adopts a extension structure，Cancel the interval iron -type joint，Extended the lifespan of the rag。

　　The results of this research marks breakthrough progress in the research of my country's Puchai Railway Marshalling Station，High reliability formed、Small maintenance workload，Tao fork products that can provide guarantee for the safe and efficient operation of the group station，Compared with 188bet sports bettingthe same type of road between the same type 188bet loginat home and abroad，Its technical indicators and service life are better。Research results have obtained a practical new patent1item.
