Relying on the "50kg/m Rail No. 9" formed by the State Railway Group'188bet game s scientific research project "Research on Key Technologies for Improving Passage Capacity in Throat Areas"、No. 12、The research results of "No. 18 Single Turnout" passed the technical review of China Railway Group。
The main technological innovations of this research result:One isInnovatively proposed the key technology for single-point traction of the No. 9 single-opening turnout elastically bendable sharp rail,The heel end of the tip rail is optimized from a union structure 188bet mobile login to an elastic and bendable structure;No. 9 turnout lengthened by 721mm,The frog heel ends are connected by joint splints,Improved the stability of the heel end connector,Extended frog service life。Second isBased on the design principles of industrial and electrical integration,Conversion optimization design method using elastic repulsion deformation of point rail,Coordinated the stroke settings of each traction point,Effectively reduces conversion resistance。Three isFor the first time, technologies such as straight and curved combined tip rail lines and planed basic rails and thickened tip rails are adopted,Extended service life of curved rails。
Developed 50kg/m rail No. 9、No. 12、No. 18 single turnout is mainly used in railway yards,Compared to the existing switches,The new turnout is safer and more reliable,Key components have longer service life,Lower cost over life、Better technical and economic efficiency,Can reduce maintenance 188bet app and repair workload by 40%~50%,Significantly reduces maintenance time,Improve station transportation efficiency,It has important practical significance for improving railway transportation efficiency。Also improves material usage efficiency,Reduced resource and energy consumption,It has practical significance for energy conservation and environmental protection。The research results have obtained 1 invention patent,4 utility model patents。
