| description | 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 bo |
