Abstract
The present invention relates to a kind of method for limiting speed of elevator car movement, including lift car 1, rack 2, gear 3 and rotary limit device 4.Rack 2 is fixed on elevator vertical guide rail, and gear 3 and rotary limit device 4 are fixed on lift car 1.It is a feature of the present invention that the translational speed of car is converted into the rotating speed of gear 3 by engaging for rack 2 and gear 3, the rotating speed of gear 3 passes to rotary limit device 4.When car translational speed exceedes setting value, the rotary limit device 4 being connected with gear 3 will take brake measure automatically, by the interaction of power, realize slowing down for the speed of car 1, so as to reach the purpose of speed limit.The stress of the speed limit process is continuous and slow, the impulsive force stopped of instantaneously being stopped different from existing safety tongs, considerably increases the security of elevator.
Description
Technical field
The present invention relates to a kind of method for limiting speed of elevator car movement.
Background technology
Bottom is rushed to summit or hit to lift car causes the main cause of injures and deaths to be lift car movement speed when occurring accident
Spend soon, limiter of speed, safety tongs and buffer three-level protective device have not been able to play a role.If can limit at any time
Speed of elevator car movement processed, it is possible to reduce or avoid lift car to rush to summit or hit the casualty accident that bottom is brought.
The content of the invention
The present invention provides a kind of method for the translational speed for interacting to limit lift car using rack-and-pinion.Gear
3 keep engaging with rack 2, are merely possible to motion association, rather than provide power for the motion of lift car.This method is completely not
Dependent on existing elevator brake system and electrical system.The present invention includes：Lift car 1, rack 2, gear 3 and rotating speed limitation
Device 4.Rack 2 is fixed with elevator hoistways, and gear 3 and rotary limit device 4 are fixed with lift car.It is a feature of the present invention that
The translational speed of car is converted into the rotating speed of gear 3 by engaging for rack 2 and gear 3, the rotating speed of gear 3 passes to rotating speed
Limits device 4.When car translational speed exceedes its setting value, the rotating speed of gear 3 can also exceed certain numerical value, now with gear
The rotary limit device 4 of 3 connections will provide corresponding brake force, and the rotating speed of gear 3 is reduced, because gear 3 and rack 2 are all the time
Engagement, by the interaction of power, so slowing down for the speed of car 1 can be realized, so as to reach the purpose of speed limit.
Brief description of the drawings
Accompanying drawing is structural representation of the invention.
