The invention relates to a planetary speed-increasing and torque-reducing safety brake. A rotatable winding drum connecting piece is installed at one end of a shell, an annular brake disc is further installed at the other end of the shell, a central rotating shaft is installed in the center of the shell, one end of the central rotating shaft is connected with the winding drum connecting piece, and the other end of the central rotating shaft penetrates through the brake disc and extends out of the shell; a multi-head thread connecting section is arranged at one end, far away from the winding drum connecting piece, of the central rotating shaft; an inertia brake disc corresponding to the brake disc is mounted on the central rotating shaft through the multi-head thread connecting section; the center rotating shaft capable of being connected with the crane roller is arranged, the inertia brake disc is installed on the center rotating shaft through the multiple threads, and when the crane roller drives the center rotating shaft to rotate in an accelerated mode, the inertia brake disc overcomes the action of the reset spring to move on the center rotating shaft towards the brake disc; the friction plate on the inertia brake disc is in contact friction with the brake disc to brake the crane drum, so that the safety of hoisting equipment can be improved.
本发明涉及一种行星增速减矩安全制动器,壳体的一端安装有可转动的卷筒连接件,壳体的另一端还安装有环状的制动盘,壳体的中心安装有中心转轴,中心转轴的一端与卷筒连接件相连,中心转轴的另一端穿过制动盘并伸出壳体;中心转轴远离卷筒连接件的一端设有多头螺纹连接段,中心转轴上通过所述多头螺纹连接段安装有与制动盘对应的惯性刹车盘;本申请通过设置可与起重机卷筒连接的中心转轴,在中心转轴上通过多头螺纹安装惯性刹车盘,在起重机卷筒带动中心转轴加速转动时,惯性刹车盘克服复位弹簧的作用在中心转轴上向制动盘移动,通过惯性刹车盘上的摩擦片与制动盘抵触摩擦对起重机卷筒进行制动,由此能提高起重设备的安全性。
