Switch rail anti-attrition device
The invention discloses a switch rail anti-attrition device which can comprise a plurality of anti-attrition steel rails, and the anti-attrition steel rails are all arranged on the side face of a target stock rail so that a buffering section can be formed between the anti-attrition steel rails and the target stock rail. According to the point rail anti-attrition device, the point rail side attrition reducing device is arranged at the front end of the point rail, the back of the rim is forcibly restrained to change the movement track of the wheel set, the wheel tread is incompletely in contact with the side face of the point rail, and the purpose of reducing the point rail side attrition is achieved. Under the condition that existing turnout structure parameters are not changed, a specific device is arranged in a railroad switch area to forcibly restrain the back of a rim to change the movement track of a wheel set, and the purpose of preventing derailment is achieved.
本发明公开了一种尖轨减磨装置，该装置可以包括若干减磨钢轨，若干所述减磨钢轨均设置于目标基本轨的侧面，以使若干所述减磨钢轨与所述目标基本轨之间形成缓冲段。本申请提供的尖轨减磨装置，通过在尖轨前端设置减少尖轨侧磨装置，强制约束轮缘背部改变轮对运动轨迹，使车轮踏面不完全接触尖轨侧面，达到减少尖轨侧磨的目的。在不改变既有道岔结构参数情况下，通过在转辙器区设置特定装置强制约束轮缘背部改变轮对运动轨迹，达到防止脱轨的目的。
