The invention provides a turnout outer locking device capable of monitoring close attaching force and a close attaching force monitoring method.The turnout outer locking device comprises a locking frame, locking iron, a strain sensor and a lock hook, a deformation groove is formed in the inner side wall of a positioning plate, and the strain sensor is arranged on the inner side wall of the positioning plate; when the lock hook is locked with the locking protrusion through the step part under the action of the locking rod, the deformation groove and the adjacent area deform, and the strain sensor is used for sensing the deformation quantity of the deformation groove and the adjacent area and monitoring the close attaching force of the switch rail to the stock rail according to the deformation quantity. Therefore, the attaching force between the switch rail and the stock rail can be monitored in real time, whether the attaching force is within a proper range or not is accurately decrypted, and the running safety of a train is guaranteed. The problems that in the prior art, a locking device does not have the function of monitoring the close attaching force in real time, the operation condition of a turnout cannot be accurately known, and train safety is affected are solved.

    本发明提供了一种可监测密贴力的道岔外锁闭装置及密贴力监测方法,该尖轨锁闭装置包括锁闭框、锁闭铁、应变传感器以及锁钩,定位板的内侧壁开设有形变槽,应变传感器设置在定位板的内侧壁上;锁钩在锁闭杆的作用下通过台阶部与锁闭凸起相互锁闭时使形变槽以及相邻区域的发生形变,应变传感器用于感应形变槽以及相邻区域的形变量并根据形变量监测尖轨对基本轨的密贴力。从而能够实时监测尖轨与基本轨的密贴力,准确了解密贴力是否处于合适的范围内,保证列车的运行安全。解决了现有技术中的锁闭装置不具备对密贴力进行实时监测的功能,导致无法准确了解道岔的运行情况,影响列车安全的问题。
