Track gauge adjustable ballastless turnout base plate fastening system
A track gauge adjustable ballastless turnout base plate fastening system comprises an iron base plate, an elastic base plate, a height adjusting base plate and a switch tie bolt, first long round holes are formed in the two ends of the iron base plate, second long round holes are formed in the two ends of the elastic base plate, and third long round holes are formed in the two ends of the height adjusting base plate; an eccentric sleeve is inserted into the first long round holes and the second long round holes, and the eccentric value between the center of a round inner hole of the eccentric sleeve and the center of the first long round hole is e; an anti-rotation boss is arranged at the upper end of the eccentric sleeve, a cover plate is arranged above the anti-rotation boss, a via hole is formed in the center of the cover plate, an anti-rotation groove is formed in the lower end face of the cover plate, and the anti-rotation boss is embedded into the anti-rotation groove; and a switch tie bolt sequentially penetrates through the via hole in the center of the cover plate, a round inner hole of the eccentric sleeve and the third long round hole and then is fixed to the switch tie, and the two ends of the iron base plate, the two ends of the elastic base plate and the two ends of the height adjusting base plate are fixedly connected to the switch tie. The eccentric sleeve is rotated by 180 degrees, so that the iron base plate is transversely moved by an eccentric value e, and the track gauge is adjusted.
一种轨距可调无砟道岔垫板紧固系统，包括铁垫板、弹性垫板、调高垫板及岔枕螺栓，所述铁垫板的两端具有第一长圆孔，弹性垫板的两端具有第二长圆孔，调高垫板的两端具有第三长圆孔；所述第一长圆孔与第二长圆孔中插装有偏心套，且偏心套的圆形内孔中心与第一长圆孔的中心偏心值为e；偏心套的上端具有防转凸台且上方设有盖板，盖板的中央具有过孔、下端面上设有防转槽，并使防转凸台嵌入防转槽中；所述岔枕螺栓依次穿过盖板中央的过孔、偏心套的圆形内孔及第三长圆孔后与岔枕固定，将所述铁垫板、弹性垫板、调高垫板的两端固定连接在岔枕上。本发明通过将所述偏心套旋转180°，使铁垫板横向移动偏心值e，从而达到轨距调整。
