Railway fastener system anchoring assembly for composite sleeper
The invention discloses a railway fastener system anchoring assembly for a composite sleeper and aims to effectively improve fatigue resistance and stability of anchoring connection of the composite sleeper and a fastener and thoroughly solve technical problems that when threaded spikes are directly screwed into the sleeper in the existing anchoring connection of the composite sleeper and the fastener, the threaded spikes are easy to loosen and pull up. The assembly comprises a fastener iron base plate, an anchoring bolt and a threaded sleeve which is embedded and fixed in a combined sleeper anchoring hole, the combined sleeper anchoring hole is composed of an upper straight hole and a lower stepped hole, the threaded sleeve is composed of an upper long round rod and a lower flange plate boss corresponding to the threaded sleeve, the top face of the lower flange plate boss abuts against the top face of the lower stepped hole, and an anchoring bonding layer is arranged in an annular gap between the inner wall of the upper straight hole and the outer wall of the upper long round rod; a vertical inner hole with internal threads is formed in the upper long round rod, and after the lower portion of the anchoring bolt penetrates through the through hole in the fastener iron base plate, the external threads of the anchoring bolt and the internal threads of the vertical inner hole form anchoring connection.
一种合成轨枕用铁路扣件系统锚固组件，以有效提高合成轨枕与扣件锚固连接的抗疲劳强度和稳定性，彻底解决现有合成轨枕与扣件锚固连接沿用直接将螺纹道钉旋入轨枕内方式时螺纹道钉易松动、易上拔的技术难题。包括扣件铁垫板、锚固螺栓和预埋固定在合成轨枕锚固孔内的螺纹套管。所述合成轨枕锚固孔由上部直孔、下部台阶孔构成，螺纹套管由与之对应的上部长圆杆、下部法兰盘凸台构成，下部法兰盘凸台顶面与下部台阶孔顶面相抵靠，上部直孔内壁与上部长圆杆外壁之间的环形间隙内设置锚固粘接层；所述上部长圆杆内设置具有内螺纹的竖向内孔，锚固螺栓下部穿过扣件铁垫板上的通孔后，其外螺纹与竖向内孔的内螺纹形成锚固连接。
