The invention relates to a mechanical trigger mechanism of a speed governor. The mechanical trigger mechanism comprises a centrifugal trigger assembly and a mechanical control connecting rod assemblywhich are arranged on a speed governor sheave, the mechanical control connecting rod assembly comprises a mechanical trigger rod, a clamp rope connecting rod, a clamp rope unit hinged with the lower end of the clamp rope connecting rod and a pulling unit hinged with the upper end of the clamp rope connecting rod, the mechanical trigger rod is hinged to a support plate of the speed governor by a hinge point, one end of the mechanical trigger rod is in contact with the centrifugal trigger assembly, and the other end of the mechanical trigger rod abuts on a contact protrusion arranged on the clamp rope connecting rod, the mechanical trigger rod is released from the clamp rope connecting rod under the trigger of the centrifugal trigger assembly, and the clamp rope unit can clamp a steel wire rope under the action of the pulling unit. Compared with the prior art, the mechanical trigger mechanism can carry out brake by using the lever principle of the clamp rope connecting rod, has reliableaction, high sensitivity, and helps to prolong the service life.
本发明涉及一种限速器机械触发机构,包括设置于限速器绳轮的离心触发组件和机械控制连杆组件,所述机械控制连杆组件包括机械触发杆、夹绳连接杆、与夹绳连接杆下端铰接的夹绳单元以及与夹绳连接杆上端铰接的提拉单元,所述机械触发杆通过铰接点铰接于限速器的支撑板上,所述机械触发杆一端与所述离心触发组件接触,另一端抵在设于夹绳连接杆上的接触凸块上,所述机械触发杆在离心触发组件的触发下,与夹绳连接杆松脱,所述夹绳单元在提拉单元的作用下夹紧钢丝绳。与现有技术相比,本发明通过利用夹绳连接杆的杠杆原理进行制动,动作可靠、灵敏度较高,有助于提高寿命。
