The explanation of elevator block construction
As shown in Figure 3, the utility model mechanical mechanism part mainly comprises a carriage 3 that is used for supporting role, and this carriage 3 is rectangular, and the diagonal angle links to each other; Each 301 termination, long limit at carriage 3 are equipped with jaw 4, and the axis hole 401 of jaw 4 is parallel with the minor face 302 of carriage 3; Sidewall 1 in the elevator is provided with the slide rail 5 of symmetry, offers slideway 501 on the slide rail 5, and it is parallel with the sidewall 1 of elevator that slideway 501 is offered direction; Its constructional drawing as shown in Figure 5 and Figure 6; Inner chamber 502 hollows of this slide rail 5, embedding in the inner chamber 502 has antifriction-bearing box 12, antifriction-bearing box 12 to be installed on the anchor shaft 13, as shown in Figure 4, and anchor shaft 13 passes in the axis hole 401 of the jaw 4 on the carriage 3, so just can carriage 3 be slided up and down along slide rail 5 by antifriction-bearing box 12; The top of carriage 3 is the lifter plates 2 of standing for the people.
At the base plate 6 of elevator adaptive damping bumper 7 for the elevator damping is installed, the top of adaptive damping bumper 7 is bearing in the long limit 301 of carriage 3 and the angle of carriage 3 diagonal lines formation, can regulate damping coefficient according to the weight of passenger on the lifter plate 2, reach good damping effect.On base plate 6, also be equipped be used to the double acting asymmetric servo cylinder 10 that prevents the elevator overload, the top of double acting asymmetric servo cylinder 10 is bearing in carriage 3 bottom centre positions, its power provides and controls by being arranged on hydraulic efficiency gear 9 on the base plate 6, and the size of its stroke is controlled by the servo electromagnetic flow valve of electric control module controls by hydraulic efficiency gear 9 inside.Double acting asymmetric servo cylinder 10 also has the decline that produces is compressed in elimination owing to adaptive damping bumper 7 when the passenger enters elevator effect.
The control unit explanation
Control unit of the present utility model comprises pressure sensor 15, speed sensor 8, acceleration pick-up 14, wherein pressure sensor 15 adopts piezoelectric pressure indicator, acceleration pick-up 14 adopts piezoelectric acceleration transducer, and speed sensor 8 adopts the laser speed sensor.The signal that pressure sensor 15, speed sensor 8 and acceleration pick-up 14 collect, through offering a micro controller system behind amplifier, filter circuit, sampling hold circuit and the A/D converter, micro controller system adopts Freescale 128 type micro controller systems in the present embodiment, micro controller system carries out analytical calculation by the programmed algorithm that sets to the signal that receives, and will calculate institute's call instruction and be transferred to adaptive damping bumper 7 and hydraulic efficiency gear 9; After adaptive damping bumper 7 and hydraulic efficiency gear 9 obtain instruction, finish the adjusting to adaptive damping bumper 7 damping sizes, and to the control of asymmetric servo cylinder elongation, the vibratory sensation of lifter plate 2 is weakened greatly, reach and weaken the passenger when taking elevator, because of the overweight dysgenic effect that human body is produced with state of weightlessness.
The control flow explanation
As shown in Figure 7, according to the running state of speed sensor 8 judgement elevators, may there be the passenger to enter or go out if speed is 0 explanation, will causes the variation of the spring 11 carrying quality of adaptive damping bumper 7 inside like this, the amount of compression of spring 11 is changed.At this moment, the elongation of double acting asymmetric servo cylinder 10 changes, and the one end contacts with carriage 3, substitutes spring 11, the quality on the bearing spring 11 fully.This moment, pressure sensor 15 can record the quality of elevator load, and micro controller system judges whether overload then, if the overload double acting asymmetric servo cylinder 10 volume quality on the bearing spring 11 always prevents from shock mitigation system is damaged.If not overload, double acting asymmetric servo cylinder 10 shortens gradually, and the spring 11 of adaptive damping bumper 7 inside is the weight on the load support 3 again.Meanwhile, micro controller system can calculate best damping damping value according to the force value that pressure sensor 15 records, and according to this result of calculation the damping of damping changing impact damper is regulated accordingly.
The acceleration pick-up 14 that is positioned at carriage 3 bottoms is measured passenger's acceleration/accel, micro controller system judges whether to meet design requirement according to acceleration information, if acceleration/accel is less, illustrate that the best damping damping value of adaptive damping bumper 7 is suitable, program is proceeded.If the accekeration of monitoring does not meet design requirement, illustrate that there is deviation in the calculating of the best damping damping value of adaptive damping bumper 7, program is returned, and the best damping damping value to adaptive damping bumper 7 calculates again, up to meeting the demands.
The utility model has weakened passenger's overweight sense and weightless sense, has strengthened the travelling comfort of elevator, and because not limited, and elevator can faster acceleration and deceleration, with the fast speeds operation, has improved the work efficiency of elevator.
The used components and parts of the utility model are commercially available known product, and related circuit is the field custom circuit, and those skilled in the art are according to the technical solution of the utility model concrete connection mode of the present utility model as can be known.
