摘　　要：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。A measuring force type lax cord protection device, uses a bridge circuit of strain foil to survey the strain situation of the bearing inner ring inside the pulley, and then calculates the pulling force of the steel cable according to the strain situation, at last judges whether has lax cord trouble in accordance with the pulling force. Making use of the principle of measuring force, the new device can avoid the disadvantages of the traditional lax cord protection device.
