Description
Technical field
This utility model relates to elevators field, particularly relates to the automatic slow-down device of overrunning of a kind of elevator box fall-proofing device.
Background technology
Elevator safety accident is constantly occurring, and particularly elevator box is out of control aloft, occurs when free fall type falls, and causes many security incidents, and such accident is all major accident, it is impossible to save.
Summary of the invention
Problem to be solved in the utility model is to provide a kind of fall-proofing device for elevator box, as the secondary fuse device of whole elevator.When elevator box is out of control aloft, when falling in free fall type, this device can make frictional force occur between elevator box and hoistway wall (or elevator case retaining rail), makes elevator box slow down, until stopping after constantly slowing down, thus avoiding the generation of extra heavy major break down.
For realizing described purpose, the automatic slow-down device of overrunning of this utility model one elevator box fall-proofing device, including: velometer, signal processor, flexible connection point, connecting rod, solenoid, friction brake；It is further characterized in that and includes: friction eceleration is taken turns；The data of described velometer are input in signal processor, start solenoid, and determine the size of solenoid driving force after described signal processor processes information；The startup of described solenoid is to drive connecting rod, allows the wheel of the friction eceleration in connecting rod contact with elevator case retaining rail, and the compactness of contact is determined by the driving force of solenoid, contact more tight, and frictional force is more big；Described connecting rod one end is fixed on flexible connection point, other end fixed friction ratio wheel；The described point that is flexibly connected is located at elevator box, and connecting rod can be flexibly connected on point and rotate；Friction brake is had in described friction eceleration wheel.
The beneficial effects of the utility model: this utility model simple in construction, durable, highly reliable, low cost of manufacture, operating cost are lower.Being the automatic slow-down device of overrunning of elevator box fall-proofing device, be also that the one in second safety system of elevator specifically protects structure, the one of elevator box fall-proofing device is embodied as part especially.
Accompanying drawing explanation
Fig. 1 is that this utility model is overrun the locations of structures schematic diagram of automatic slow-down device.
Detailed description of the invention:
Below in conjunction with Fig. 1, this utility model is described in detail, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.
Embodiment: the automatic slow-down device of overrunning of this utility model one elevator box fall-proofing device, including velometer, signal processor, flexible connection point 27, connecting rod 28, solenoid 29, friction brake 30；It is further characterized in that and includes: friction eceleration wheel 31.
The present embodiment is further arranged to: the data of described velometer are input in signal processor, starts solenoid 29, and determine the size of solenoid driving force after described signal processor processes information；The startup of described solenoid 29 is to drive connecting rod 28, allows the wheel of the friction eceleration in connecting rod 28 31 contact with elevator case retaining rail, and the compactness of contact is determined by the driving force of solenoid 29, contact more tight, and frictional force is more big；Described connecting rod 28 one end is fixed on flexible connection point 27, other end fixed friction ratio wheel 31；The described point that is flexibly connected is located at elevator box 26, and connecting rod 28 can 27 rotations on flexible connection point；Friction brake 30 is had in described friction eceleration wheel 31.
Operation principle:
When the speed that velometer is measured is in the scope of predetermined value, automatic slow-down device of overrunning is normal condition；When the speed that velometer is measured is beyond predetermined value, signal processor will allow solenoid start, electromagnetic force will promote connecting rod, friction eceleration wheel is made to contact with elevator case retaining rail, magnetic force is more big, contact more tight, frictional force is more big, along with the decline of elevator case, drive friction eceleration wheel to rotate, in taking turns due to friction eceleration, have friction brake, the decline of elevator case is just slowed down, decelerating to the speed that velometer measures when having returned to predetermined value, signal processor will allow solenoid quit work, and automatic slow-down device of overrunning returns to normal condition；Continuing in the process declined, when the speed that velometer is measured is again beyond predetermined value, automatic slow-down device of overrunning can make again action just now, allows the decline of elevator case slow down and lowers, and after speed is normal, automatic slow-down device of overrunning returns to normal condition；In the process making a reservation for startup, stopping that elevator normally uses, if there being the above excess speed event of secondary to occur, it is also possible to be decelerated to arresting stop with this signal deactivation, make elevator box stuck, to guarantee safety.
Described above to the disclosed embodiments, makes professional and technical personnel in the field be capable of or uses this utility model.The multiple amendment of these embodiments be will be apparent from for those skilled in the art, and generic principles defined herein when without departing from spirit or scope of the present utility model, can realize in other embodiments.Therefore, this utility model is not intended to be limited to the embodiments shown herein, and is to fit to the widest scope consistent with principles disclosed herein and features of novelty.
