The invention relates to the field of elevators, and discloses an elevator steel wire rope broken wire detection device which comprises a detection module and a signal processing module, the detection module comprises a shell, a cavity allowing a steel wire rope to penetrate through is formed in the shell, and the cavity is wrapped by a first electromagnetic coil, a second electromagnetic coil and a detection coil; all the coils are electrically connected with the signal processing module, and the signal processing module is used for being connected with an elevator main controller and a central machine room. Certain direct current is applied to the two sets of electromagnetic coils to magnetize the steel wire rope between the two sets of electromagnetic coils, when the steel wire rope is broken, electric pulses are detected through the detection coils, whether the broken wire is generated or not is judged through the signal processing module, and therefore an alarm signal is generated. Electromagnetic detection is adopted, the device does not make contact with the steel wire rope, normal operation of an elevator is not interfered, the beneficial effects of being high in response speed and sensitivity are achieved, the safety performance of the elevator is improved, and the steel wire rope can be conveniently overhauled.

    本发明涉及电梯领域,公开了一种电梯钢丝绳断丝检测装置,包括检测模块和信号处理模块,所述检测模块包括壳体,所述壳体内部有使钢丝绳穿过的空腔,所述空腔被第一电磁线圈、第二电磁线圈和检测线圈包覆,所有线圈均与信号处理模块电气连接,所述信号处理模块用于连接电梯主控制器和中心机房;通过对两组电磁线圈施加一定的直流电流,磁化中间的钢丝绳,当钢丝绳有断丝时,通过检测线圈检测到电脉冲,通过信号处理模块,将判断是否产生了断丝,从而产生报警信号。本发明采用电磁式检测,装置不与钢丝绳接触,不干扰电梯正常运行,具有反应速度快、灵敏度高的特点,提高了电梯安全性能,也方便对钢丝绳进行检修。
