Embodiment
The utility model is further illustrated with reference to the accompanying drawings and examples:
Referring to Fig. 1-3.
Slow down the utility model discloses one kind braking disc type used during elevator falling and stop falling unit, including in elevator hoistways 2 Car 3, both sides are respectively equipped with elevator T type guide rail 2 in the elevator hoistways 1, and velocity pick-up is provided with the outside of the casing of car 3 Device 10, bottom are provided with automatically controlled ECU 9, and the velocity sensor 10 is connected with automatically controlled ECU, and the lower section both sides of car 3 are set respectively There are an only drop clamp 4, the only drop clamp 4 are groove type and are coated on the both sides of T-shaped guide rail 2, described only to drop the two of clamp 4 Inwall is respectively equipped with sliding groove 20, and matched brake piston 18 is provided with the sliding groove 20, the brake piston 18 Glide direction is vertical with elevator traffic direction, and the brake piston 18 exerts a force to T-shaped guide rail via automatically controlled ECU control driver elements 2 motions only drop its locking.
Velocity sensor 10, automatically controlled ECU 9, the buzzer 11 of elevator;The elevator car speed collector is by being arranged at The velocity sensor 10 of car side is formed, and the lift car 3 is done vertically along the T-shaped guide rail 2 being fixed in elevator hoistways 1 Elevating movement;The used during elevator falling, which slows down, only drops brains of the automatically controlled ECU 9 for whole device, completes to sensor collection information Analysis and processing, and the action of executing agency is controlled, it is the core component of whole device;The used during elevator falling, which slows down only to drop, to be performed Mechanism includes only drop clamp 4, master cylinder 5, piston rod 6 and back-moving spring 12, and a pair of brakings work is provided with inside the clamp Plug 18, described one end of brake piston 18 are fixed with friction plate 19, and the place that is contacted with brake fluid of brake piston 18 be placed with it is close Sealing 17, the leakage of brake fluid is prevented, described one end of piston rod 6 is located in master cylinder 5, and is rigidly connected in master cylinder piston 13 On, the affixed block permanent magnet 7 of the piston cylinder other end, the same installation in place that described master cylinder piston 13 contacts with brake fluid There is the leakage-preventing part sealing ring 14 of sealing, the back-moving spring 12 is located inside master cylinder 5, and is enclosed on piston rod 6, with The motion of piston rod and stretching and compression variation occurs;The alarm mechanism is buzzer 11, and the buzzer is arranged at electricity The terraced top of car 3, automatically controlled ECU 9 instruction is only dropped by receiving used during elevator falling deceleration, sends alert help information.
As shown in Fig. 2 system work-based logic principle is that velocity sensor 10 is adopted to the speed of lift car 3 first Collection detection, then holds information conveyance to automatically controlled ECU 9, logic analyses and calculating of the automatically controlled ECU 9 Jing Guo internal structure, control Whether is the action of row mechanism (used during elevator falling deceleration Zhi Jiang executing agencies and alarm mechanism).
As shown in figure 3, when elevator normal operation, executing agency (used during elevator falling deceleration Zhi Jiang executing agencies and alarming machine Structure) will not trigger action, electromagnet 8 will not drive permanent magnet 7 to move, and back-moving spring 12 is located at original state, friction now Piece 19 is separated with elevator T type guide rail 2, and the present apparatus does not interfere with the normal operation of elevator original system.
When elevator occur steel wire rope come off or be broken, the accidental falling accident such as the damage of lift when, velocity sensor 10 The instantaneous falling speed of lift car 3 is detected, and is conveyed to automatically controlled ECU 9 and carries out analysis calculating, when falling speed is beyond setting During value range, triggering executing agency (used during elevator falling deceleration Zhi Jiang executing agencies and alarm mechanism) action, now electromagnet 8 drives Permanent magnet 7 moves, and active force is transferred to master cylinder piston 13 by piston rod 6, and then is converted into pressure and acts on brake fluid, due to Liquid has Incoercibility, so pressure being delivered to up to brake piston 18 via liquid, and then promote friction plate 19 and electricity The T-shaped guide rail 2 of ladder contacts, and produces frictional force, with the motion of piston rod 6, the pressure between friction plate 19 and elevator T type guide rail 2 Gradually increase, frictional force also constantly raises with the increase of pressure, and lift car 3 will gradually slow down, when frictional force is enough gram When taking gravity when lift car 3 declines, brake in some position in elevator hoistways 1, reach the purpose for preventing used during elevator falling, Now back-moving spring 12 is in extended state;At the same time, alarm mechanism starts to act, and automatically controlled ECU 9 sends instruction, buzzer 11 send alert help signal;In addition, after failture evacuation, to the manual power-off restoration of electromagnet, driving force disappears therewith, electricity Ladder falls, and only falling unit comes back to its initial position in the presence of back-moving spring 12 for deceleration, realizes the effect recycled.
