The invention provides a turnout external locking device with precise and controllable close attaching force and a close attaching force control method, the locking device comprises a locking frame, locking iron, a lock hook and a plurality of close attaching adjusting pieces, and an adjusting gap is formed between the locking iron and the locking frame; the plurality of close-fitting adjusting pieces are elastic pieces, and part or all of the plurality of close-fitting adjusting pieces are detachably mounted in the adjusting gap in an overlapping manner; each closely-attached adjusting piece has preset rebound thrust and preset compression thickness, and when the locking iron and the locking frame are mutually locked, the multiple closely-attached adjusting pieces are compressed to a preset state so as to generate the preset rebound thrust; and when the lock hook and the locking iron are mutually locked, the resultant force of the rebound thrust of the plurality of overlapped closely-attached adjusting pieces enables the point rail to generate closely-attached force with preset magnitude on the stock rail. Therefore, the attaching force of the switch rail to the stock rail can be accurately controlled within the range that the standard preset value slightly floats up and down, accurate and quantitative control over the attaching force of the switch rail is achieved, and safe operation of a train is guaranteed.

    本发明提供了一种密贴力精确可控的道岔外锁闭装置及密贴力控制方法,该锁闭装置包括锁闭框、锁闭铁、锁钩和多个密贴调整件,锁闭铁与锁闭框之间形成调节间隙;多个密贴调整件均为弹性件,多个密贴调整件中的部分或全部以叠加方式可拆卸地安装在调节间隙内;每个密贴调整件具有预定的反弹推力和预定的压缩厚度,锁闭铁与锁闭框相互锁紧时将多个密贴调整件压缩至预设状态以产生预定的反弹推力;锁钩与锁闭铁相互锁闭时,多个叠加的密贴调整件的反弹推力的合力使尖轨对基本轨产生预定大小的密贴力。从而能够将尖轨对基本轨的密贴力精确控制在标准预定值上下小幅浮动的范围内,实现尖轨密贴力精确以及定量化控制,保证列车的安全运行。
