Overall flexible toothed rail turnout and design method thereof
The invention relates to an integral flexible toothed rail turnout and a design method thereof. The integral flexible toothed rail turnout is composed of a slide plate, a steel rail, a toothed rail, a T-shaped sleeper, a pi-shaped sleeper, a driving sleeper, a connecting block assembly, a fastener, a driving device and the like. The steel rails on the two sides of the turnout are fixedly connected with the T-shaped sleepers and the pi-shaped sleepers through fasteners or other modes respectively, and the toothed rail is clamped between the sleepers on the left side and the right side. The adjacent sleepers restrain the positions of the rails in the width direction through the connecting block assemblies, bending deformation of the rails in the length direction is released, and therefore the switching force is reduced, and the fatigue life is prolonged. The toothed rail is fixedly connected with the slide plate through a connecting block assembly at the fixed end. The connecting block assembly is composed of two connecting blocks, bolts and nuts and fixed to the two sides of the toothed rail. The driving device is installed at the turnout switch end of the tooth track, so that the sleeper is driven to do reciprocating motion, and turnout switch is achieved. The turnout has the advantages that firstly, the turnout switching force is small, and the fatigue life is long; 2, the structure is simple, and the construction is convenient; and 3, the device can be expanded and applied to railways, urban rail transit and other turnouts.
本发明涉及一种整体可挠式齿轨道岔及其设计方法，整体可挠式齿轨道岔由滑床板、钢轨、齿轨、T型轨枕、π型轨枕、驱动轨枕、连接块组件、扣件、驱动装置等组成。道岔两侧钢轨通过扣件或者其他方式分别与T型轨枕、π型轨枕进行固定连接，齿轨夹持在左右两侧的轨枕中间。相邻轨枕通过连接块组件约束轨道宽度方向的位置，释放轨道长度方向弯曲变形，从而降低转辙力、提供疲劳寿命。齿轨通过固定端的连接块组件与滑床板进行固定连接。连接块组件由两个连接块和螺栓、螺母组成，固定在齿轨两侧。驱动装置安装在齿轨道岔转辙端，使驱动轨枕进行往复运动，实现道岔转辙。优点：一是道岔转辙力小、疲劳寿命高；二上具有结构简单、施工方便的特点；三上可扩展应用在铁路、城市轨道交通其他道岔中。
