Method for reducing insufficient displacement of turnout switch rail
The invention discloses a method for reducing insufficient displacement of a turnout switch rail, which comprises the following steps of: S1, trying to lay a group of high-speed turnouts with the same model as the model to be researched, setting specific working conditions of different lengths from the last traction point to the fixed end, and testing the insufficient displacement, the conversion force and the minimum rim groove; s2, determining a movement amount according to a test result; s3, the number X of moving pillow spans is determined according to the movement amount; s4, according to the offset distance between the switch rail and the stock rail after sleeper span movement, whether an enough offset distance l exists for placing the iron base or not is judged, and if yes, the step S5 is executed; otherwise, performing the step S6; s5, replacing X slide plates related to the actual high-speed turnout to be researched with fixed base plates with iron seats, and carrying out the step S7; s6, replacing X slide plates related to the actual high-speed turnout to be researched with fixed base plates with beveled edge iron seats; and S7, changing the actual high-speed turnout.
本发明公开了一种减小道岔尖轨不足位移的方法，包括以下步骤：S1、试铺一组与拟研究型号相同的高速道岔，设置最后一个牵引点至固定端不同长度的具体工况，测试不足位移、转换力以及最小轮缘槽；S2、根据测试结果确定移动量；S3、根据移动量确定移动的枕跨数量X；S4、根据枕跨移动后尖轨与基本轨之间的支距，判断是否有足够的支距l放置铁座，是则进行步骤S5；否则进行步骤S6；S5、将实际的拟研究的高速道岔所涉及到的X块滑床板更换为带铁座的固定垫板，并进行步骤S7；S6、将实际的拟研究的高速道岔所涉及到的X块滑床板更换为带斜边铁座的固定垫板；S7、对实际的高速道岔进行更改。
