Abstract
The present invention relates to a kind of car to move method for limiting speed, including counterweight 1, rack 2, gear 3, speed-limiting device 4 and car 5.It is a feature of the present invention that make with counterweight 1 that speed is equal using traction sheave as association all the time using car 5, the principle of elevating movement in opposite direction, by controlling the translational speed of counterweight 1 to reach the translational speed of limitation car 5.When car 5, which exceeds the speed limit, to be lifted, counterweight 1 is also in the jacking condition that exceeds the speed limit, and the active force of gear 3 is passed to by speed-limiting device 4, realizes slowing down for the speed of counterweight 1, so as to realize the limitation to the translational speed of car 5.
Description
Technical field
The present invention relates to a kind of car to move method for limiting speed, belongs to elevator industry.
Background technology
It is that car translational speed is too fast when accident occurs that the main reason for bottom causes injures and deaths is rushed to summit or hit to lift car,
Limiter of speed, safety tongs and buffer three-level protective device have not been able to play a role.If car translational speed can be limited, just
It can reduce or avoid car to rush to summit or hit casualty accident caused by bottom.Current most elevators are all using car, draged
The structure of running wheel and counterweight, in the presence of traction sheave, car and counterweight remain identical translational speed.This method passes through
The translational speed of limitation counterweight reaches the purpose of control car translational speed.
The content of the invention
The present invention provides a kind of method that the translational speed of counterweight is limited using rack-and-pinion interaction, including：It is right
Weigh 1, rack 2, gear 3, speed-limiting device 4 and car 5.Rack 2 is fixed in elevator hoistways, gear 3 and speed-limiting device 4 and counterweight 1
It is fixed.When car 5, which exceeds the speed limit, to be lifted, counterweight 1 is also in the jacking condition that exceeds the speed limit, and the work of gear 3 is passed to by speed-limiting device 4
Firmly, slowing down for the translational speed of counterweight 1 is realized, so as to realize the limitation to the translational speed of car 5.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention.
Embodiment
Present elevator is substantially is used as elevator operation power by traction system, and elevator and counterweight bear steel wire rope drawing
Power, steel wire rope moment are in tensioning state, and car and counterweight make that speed is equal using traction sheave as association all the time, liter in opposite direction
Drop motion.As shown in Figure 1, gear 3 keeps engaging with rack 2, but is merely possible to motion association, rather than is carried for the motion of counterweight
For power.The present invention includes：Counterweight 1, rack 2, gear 3, speed-limiting device 4 and car 5.Rack 2 is fixed in elevator hoistways, tooth
Wheel 3 and speed-limiting device 4 are fixed with counterweight 1.It is a feature of the present invention that the lifting speed of counterweight 1 is passed through into rack 2 and gear 3
Engagement is converted into the rotating speed of gear 3, and the rotating speed of gear 3 passes to speed-limiting device 4.When the lifting speed of counterweight 1 is set more than it
During value, the rotating speed of gear 3 can also exceed certain numerical value, and the speed-limiting device 4 now connected with gear 3 will provide corresponding braking
Power, the rotating speed of gear 3 is reduced, because gear 3 engages all the time with rack 2, counterweight can be realized by the interaction of power
1 speed slows down.Because car 5 makees with counterweight 1 that speed is equal using traction sheave as association all the time, elevating movement in opposite direction,
Slowing down for the translational speed of counterweight 1 directly results in slowing down for the translational speed of car 5 by traction sheave, and car 5 is moved so as to realize
The limitation of speed.
