The invention discloses a pulley assembly and a steel wire rope multiplying power detection method applying the pulley assembly, the pulley assembly comprises a pulley, a trigger screw rod, a detection module and a reset spring, a plurality of containing cavities are formed in the outer wall of the circumference of the pulley at equal intervals, and each containing cavity comprises a first step, a second step and a third step; the trigger screw rod is installed in the second step, the head end of the trigger screw rod penetrates through the first step, the detection module is installed in the third step, the reset spring is arranged at the tail end of the trigger screw rod and the head of the detection module in a sleeving mode, and when the trigger screw rod is pressed, the reset spring is pressed as well; and at the moment, the trigger screw triggers the detection module to receive a position detection signal and sends the detected signal to the controller, and when the trigger screw is released from pressure, the reset spring enables the trigger screw to reset, and the detection module loses the detection signal, so that the problem that the moment limiter is inaccurate due to the multiplying power error of a steel wire rope of an engineering mechanical product can be effectively solved; and the detection precision is high.
本发明公开一种滑轮组件及应用该轮组件的钢丝绳倍率检测方法,滑轮组件包括滑轮、触发螺杆、检测模块以及复位弹簧,滑轮圆周外壁等距的设置有多个容腔,每个所述容腔包括第一台阶第二台阶和第三台阶,触发螺杆安装在所述第二台阶内,其头端贯穿所述第一台阶,检测模块安装在所述第三台阶内,复位弹簧套设在所述触发螺杆的尾端以及检测模块的头部上,其中,当触发螺杆受压后,复位弹簧同样受压,此时触发螺杆触发检测模块接收位置检测信号,并将检测的信号发送至控制器,当触发螺杆受压解除时,复位弹簧使触发螺杆复位,检测模块失去检测信号,本发明可有效解决工程机械产品钢丝绳倍率错误引起力矩限制器不准的问题,且检测精度高。
