新型测力式松绳保护装置使用应变片电桥电路测量滑轮内轴承内圈的应变情况,之后根据应变情况计算出钢丝绳中的拉力大小,最后根据拉力大小判断是否发生了松绳故障。由于采用测力原理因而避免了传统松绳保护装置的不知之处。
The new force-measuring type slack rope protection device uses the strain gauge bridge circuit to measure the strain of the bearing inner ring in the pulley. After that, the tension in the wire rope is calculated according to the strain situation, and finally the slack rope fault is judged according to the pulling force. As a result of the principle of force measurement and thus avoid the traditional loose rope protection device I do not know.
