Abstract
The utility model relates to elevator braking devices, and provides an electromagnetic type elevator braking device which comprises a mounting seat, braking arms, a braking spring, brake blocks and an electromagnet switch-on device. A pressure sensor used for detecting braking pressure is arranged on one brake block and is connected with a pressure sensor detecting circuit, and the pressure sensor detecting circuit is electrically connected with a processor in an elevator control cabinet. In the braking process, when the processor detects that the pressure value of a pressure signal detected by the pressure sensor does not reach requirements, the processor sends out an alarm signal to an alarm device and sends out an emergent elevator stop signal to an elevator emergent stop return circuit to avoid accidents. The electromagnetic type elevator braking device can effectively avoid dangers due to elastic fatigue and insufficient pressure of the braking spring, rusting and inflexible rotation of a hinged shaft, and insufficient braking torque caused by deadly rusting of an electromagnet or foreign matters, and is high in safety coefficient.
