Railway turnout heel end movable joint
The invention relates to a railway turnout heel end movable joint which comprises a track heel base plate, a stock rail, a switch rail, spacer iron, a track heel outer rail brace, a track heel inner rail brace, a track heel clamping plate, a left transverse high-strength bolt assembly and a right transverse high-strength bolt assembly. The left transverse high-strength bolt assembly is used for locking and fixing the other end of the track heel outer rail brace and the spacer iron to rail webs on the two opposite sides of the stock rail respectively. The right transverse high-strength bolt assembly is used for locking and fixing the other end of the track heel inner rail brace, the track heel clamping plate and the spacer iron to rail webs on the two opposite sides of the switch rail respectively. And the right transverse high-strength bolt assembly is further sleeved with a sleeve in a matched mode on a screw rod arranged between rail webs of the switch rail in a penetrating mode. The integral connection stability of the movable joint structure is improved, the problem that the matching position of the shaft shoulder and the spacer iron of the original structure is easy to wear is solved, the service life of the movable joint structure is prolonged, and the reliability of the movable joint structure is improved.
本发明涉及一种铁路道岔跟端活接头，其包括辙跟垫板、基本轨、尖轨、间隔铁、辙跟外轨撑、辙跟内轨撑、辙跟夹板、左横向高强螺栓组件和右横向高强螺栓组件；左横向高强螺栓组件用于将辙跟外轨撑的另一端和间隔铁分别锁紧固定于基本轨的相对两侧轨腰上；右横向高强螺栓组件用于将辙跟内轨撑的另一端、辙跟夹板和间隔铁分别锁紧固定于尖轨相对两侧的轨腰上；且右横向高强螺栓组件在穿设于尖轨的轨腰之间的螺杆上还匹配套装有套筒。本发明在提升活接头结构整体连接稳定性的同时，解决了原结构轴肩和间隔铁配合位置易磨损的问题，增加了活接头结构形式的使用寿命及可靠性。
