Long and short point rail dislocation device of movable point rail frog
The invention is suitable for the technical field of rail transit, and provides a long and short point rail dislocation device of a movable point rail frog. The device comprises a rail body assembly,a point rail connecting assembly and a sleeper connecting assembly, and the rail body assembly comprises a wing rail, a long point rail, a short point rail, a rail head rail bottom gap, an oblong holeand a sleeper. The cover plate and the oblong hole are arranged, the cover plate penetrates through the oblong hole of the long point rail and is propped against the rail waist of the short point rail, when bolts are fastened, the cover plate firstly pushes against the rail web of the short point rail, meanwhile, certain gaps are reserved between the cover plate and the steel rail gasket and between the rail heads and the rail bottoms of the long point rail and the short point rail, and the gap between the cover plate and the steel rail gasket can be adjusted through an adjusting piece, so itis guaranteed that the fastening force of the bolts is partially transmitted to the long point rail; and the long point rail and the short point rail are allowed to move relatively in the longitudinal direction at the splicing position, so the problem that the long point rail and the short point rail cannot move at the splicing position to influence conversion resistance is solved, and the conversion resistance of the long point rail and the short point rail is reduced.
本发明适用于轨道交通技术领域，提供了一种可动心轨辙叉长短心轨错动装置，包括轨体组件、心轨连接组件和轨枕连接组件，所述轨体组件包括翼轨、长心轨、短心轨、轨头轨底间隙、长圆孔和轨枕；通过设置盖板和长圆孔，使得盖板穿过长心轨长圆孔顶在短心轨的轨腰位置，螺栓紧固时盖板先顶紧短心轨轨腰，同时确保盖板与钢轨垫圈、长心轨与短心轨的轨头和轨底留有一定间隙，对于盖板与钢轨垫圈的间隙可利用调整片调整，确保螺栓紧固力部分传递给长心轨，长心轨和短心轨允许在拼接位置沿纵向相对错动，解决了长心轨和短心轨在拼接位置无法错动对转换阻力影响的问题，降低了长心轨和短心轨转换阻力。
