The invention discloses a sliding tank detection method which comprises the following steps: acquiring, by a controller, a detection signal value of an encoder at a preset time interval to obtain the actual operation angular speed of a winding drum, or acquiring the actual operation linear speed of an elevator in combination with the outer diameter size of the winding drum; and if a judgment result is that the actual operation linear speed exceeds the preset operation linear speed or the actual operation angular speed exceeds the preset operation angular speed, controlling, by the the controller, the motor to stop rotating and controlling, by the controller, a band-type brake device to brake the winding drum. According to the detection method, the rotating speed of the winding drum is directly detected, and response is made immediately when the speed of the winding drum is abnormal, so that the descending distance of accidental sliding can be reduced. The invention further provides a sliding tank detection system which comprises an encoder used for detecting the rotation angle of the winding drum and the controller, wherein the encoder is in signal connection with the controller. The detection system can utilize the sliding tank detection method for judgment, and the same technical effect can be achieved.

    本发明公开一种滑罐检测方法,控制器以预定时间间隔获取编码器的检测信号值,得到卷筒的实际运行角速度、或者结合卷筒的外径尺寸得到提升机的实际运行线速度;如果判断结果是实际运行线速度超过预定运行线速度,或者实际运行角速度超过预定运行角速度,则控制器控制电机停止转动,并控制抱闸装置对卷筒制动;该检测方法直接检测了卷筒的转动速度,在卷筒速度出现异常时立刻做出反应,可以减少意外滑落的下降距离。本发明还提供一种滑罐检测系统,包括用于检测卷筒转动角度的编码器和控制器,编码器信号连接于控制器;该检测系统能够利用上述的滑罐检测方法进行判断,可以实现相同的技术效果。
