The invention discloses an elevator safety brake. The brake comprises a brake body composed of a base body, two brake arms, a screw, two braking shoe brakes, a brake disc, two spring bodies, a springscale, a brake rod, a plunger and an electromagnet. A secondary brake mechanism is arranged at the bottom ends of the two brake arms, the secondary brake mechanism comprises a secondary brake shoe, abrake pad, primary connecting arms, secondary connecting arms, an elastic bending mechanism and fixing bolts, the brake pad is arranged on the upper end surface of the secondary brake shoe, and the upper end surface of the brake pad is closely attached to the annular side surface of the brake disc. By adding the secondary brake mechanism to the device, when the brake is closed and the brake disc is encircled by the braking shoe brakes for braking, the brake arms are skillfully used, and the secondary brake mechanism is compressed to force the secondary brake mechanism to bend upwards to make contact with the annular bottom end surface of the brake disc to assist the brake disc for braking, so that the braking inertia force is evenly dispersed, and the braking effect is increased.

    本发明公开了一种电梯安全制动器,包括由基座主体、两个制动器臂、螺杆、两个制动瓦闸、制动盘、两个弹簧主体、簧标尺、制动杆、柱塞以及电磁铁组成的制动器主体,两个所述制动器臂底端设置有二级制动机构,所述二级制动机构包括二级制动瓦、制动闸片、主连接臂、次连接臂、弹性弯折机构以及固定螺栓构成,所述制动闸片设置在二级制动瓦的上端面,且制动闸片的上端面紧贴制动盘的环形侧面,通过在该装置中添加二级制动机构,巧妙的运用制动器臂在合闸通过制动瓦闸环抱制动盘进行制动时,压缩二级制动机构迫使其向上弯曲拱起接触制动盘环形底端表面对其辅助加以制动,从而使得制动惯性力度均匀分散,增加制动效果。
