The invention relates to a turnover tip hiding mechanism for a suspension type monorail movable core turnout, which can effectively eliminate the defect that a 5mm step exists due to a structural reason after the tip of a follow-up core rail of the suspension type monorail movable core turnout is tightly attached to the inner wall of a turnout beam, and ensures stable vehicle passing. The force is transmitted to a space connecting rod to drive a right-angle crank in the sliding block assembly to rotate, the gyroscopic moment is converted into displacement thrust through a first-stage connecting rod, a sliding block and a second-stage connecting rod in the sliding block assembly, and therefore a driven connecting rod in the swing arm mechanism is driven to move, and the driven connecting rod avoids a return stroke dead point in the moving process through an included angle slotting connecting rod in the moving process. The degree of freedom of a driven connecting rod is increased through a middle stable connecting rod, then an overturning swing arm in the swing arm mechanism is driven to rotate, the overturning swing arm in the swing arm mechanism is hinged to a straight-curve overturning unit, finally, rotation overturning of the straight-curve overturning unit is achieved, switch rail switching is completed, overturning switching of a straight-curve functional face is achieved, and tip hiding and slab staggering are achieved. And the turnout line type and the vehicle passing smoothness are ensured.
本发明涉及一种能够有效消除悬挂式单轨可动芯道岔随动芯轨尖部与道岔梁内壁密贴后因结构原因存在5mm台阶缺陷,确保过车平稳的悬挂式单轨可动芯道岔翻转藏尖机构,驱动机构中外力推杆开始推动推动曲柄轴组件转动,将力传递给空间连杆,带动滑块组件中直角曲柄转动,通过滑块组件中一级连杆、滑块及二级连杆,将回转力矩转化为位移推力,从而带动摆臂机构中从动连杆移动,从动连杆移动过程中通过夹角开槽连杆避开运动过程中回程死点,通过中间稳定连杆增加从动连杆的自由度,再带动摆臂机构中翻转摆臂转动,其中摆臂机构中翻转摆臂与直曲翻转单元铰接,最终实现直曲翻转单元的回转翻转,完成尖轨切换,实现翻转切换直曲功能面且藏尖隐蔽错台,保证道岔线型及过车平顺性。
