Description

[0002] The structure and technology of speed governor device for elevator have been developed rapidly in recent years, and the currently widely used speed governors mainly include pendulum type speed governor and centrifugal type speed governor, especially the centrifugal flail type speed governor is most widely used, which plays an important role in ensuring the safe and stable operation of elevator. The existing centrifugal flail type speed governor mainly comprises a bracket, a rope wheel, a ratchet wheel, a pawl, a pressure pawl, two flail components, a flail connecting rod, an adjusting screw, a rope pressing and beating assembly and a limit switch. The centrifugal flail type speed governor uses the principle that the centrifugal force increases with the change of rotating speed to complete the action. When the rope wheel of the speed governor rotates, the two flails in the speed governor tend to move away from the rotation center due to the centrifugal force. Once the speed exceeds the limit, the flails trigger the overspeed limit switch, and then the pressure pawl, the pawl, the ratchet wheel and the rope pressing and beating assembly produce a safety clamp action, so that the rope pressing plate in the rope pressing and beating assembly and the rope wheel clamp the steel wire rope, to avoid the phenomenon of rapid operation of the elevator due to failure, thereby ensuring safety. The centrifugal flail is generally produced by using a special mold, and needs to be detected by a gauge after production to determine whether it is qualified.
