Sleeper nylon sleeve rotary taking device
The invention relates to a sleeper nylon sleeve rotary taking device for railway engineering anchor changing operation. The upper portion of a screw-in body is connected with an electric wrench, and aguide column is arranged at the lower end of the screw-in body and has the same diameter as an unthreaded hole in the bottom of a nylon sleeve; the upper part of the guide column is a guide cone witha cone frustum structure; the upper part of the guide cone is a screw cone with threads; the screw cone comprises an upper section and a lower section, the upper section of the screw cone is cone frustum-shaped threads, and the lower section of the screw cone is cylindrical threads; the outer diameter of the upper end of the cone frustum-shaped threads is greater than the inner diameter of the unthreaded hole in the bottom d of the nylon sleeve; the outer diameter of the lower end of the cone frustum-shaped threads is equal to that of the cylindrical threads; the outer diameter of the cylindrical threads is larger than the bottom diameter of the internal thread of the nylon sleeve and smaller than the bottom diameter of the external thread of the nylon sleeve; the diameter of the small end of the guide cone is smaller than the small diameter of the internal thread of the nylon sleeve; the diameter of the large end of the guide cone is the outer diameter of the cylindrical threads; thethreads of the screw cone are uniformly distributed in the axial direction; and chip grooves are formed among the threads; a stop step is arranged at the upper end of the screw cone. Full mechanization of railway line anchor changing operation is achieved, and the anchor changing operation efficiency can be improved.
本发明涉及一种铁路工务改锚作业用轨枕尼龙套旋取器。其旋进主体上部与电动扳手联结，旋进主体下端为导柱，导柱与尼龙套底部光孔直径相同；导柱上部为圆锥台结构的导锥，导锥上部为带有丝牙的丝锥体；丝锥体包括上、下两段，上段丝锥体为圆锥台型丝牙,下段丝锥体为圆柱型丝牙；圆锥台型丝牙上端外径大于尼龙套上端光孔内径，圆锥台型丝牙下端外径与圆柱型丝牙相同；圆柱型丝牙外径大于尼龙套内螺纹底径，小于尼龙套外螺纹底径；导锥小端直径小于尼龙套内螺纹小径，大端直径为圆柱型丝牙外径；丝锥体的丝牙轴向均布，丝牙之间形成排屑槽；丝锥体上端设有止进台阶。本发明实现了铁路线路改锚作业完全机械化，能够提高改锚作业效率。
