The specific embodiment

Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.

As shown in Figure 1, a kind of circulating elevator with multiple compartments comprises two closed annular hoistway rails and is arranged on 5 double cars 3 on the closed annular hoistway rail, and closed annular hoistway rail is to be made of coplane and the inner race track 1 that is parallel to each other and outer race track 2.Inner race track 1 and outer race track 2 all are by two straight rails and two circular rails that the circular arc rail constitutes.Two groups of parallel inner race tracks 1 and outer race track 2 lay respectively at the Si Jiaochu of double cars 3.The madial wall of inner race track 1 is smooth, and lateral wall has the sawtooth 15 that is used for transmission; The madial wall of outer race track 2 has sawtooth 15, and lateral wall is smooth.Double cars 3 comprises sedan-chair face 4 and following sedan-chair face 5, double cars 3 is provided with engine installation 6, brake equipment and detecting device, engine installation 6, brake equipment and detecting device link to each other with elevator main controller by circuit, by car entrance controller control elevator main controller, to realize the steady lifting of car.Engine installation 6 is installed in the Si Jiaochu of double cars 3, change speed gear box 8, worm screw 9 and speed controller 10 that engine installation 6 comprises electrical motor 7, links to each other with electrical motor, as shown in Figure 2.Worm screw 9 is matched with sawtooth 15 on inner race track 1 and the outer race track 2, and electrical motor 7 drives worm screws 9 by change speed gear box 8 and rotates, and worm screw 9 climbs or descends along inner race track 1 and outer race track 2, realizes the lifting of double cars 3.Brake equipment 14 comprises energy disperser and electromagnetic brake device, and energy disperser is a hydraulic ram, and electromagnetic brake device comprises electromagnet, brake disc and brake clamp.Detecting device is installed between sedan-chair face 4 and the following sedan-chair face 5, and detecting device comprises and be used to the displacement pickup 12 that detects the obliquity sensor 11 of car level degree and be used to detect distance between adjacent two cars, as shown in Figure 3.The straight rail of inner race track 1 and outer race track 2 and circular arc rail intersection are equipped with contact switch 13, and obliquity sensor 11 links to each other with elevator main controller by contact switch 13, and displacement pickup directly links to each other with elevator main controller.

Quadruplet engine installation 6 on a double cars 3 lays respectively on four angles of double cars 3, and quadruplet engine installation 6 starts simultaneously.When double cars 3 moves on the straight rail of inner race track 1 and outer race track 2, quadruplet engine installation 6 moves with speed, so that the power of double cars 3 liftings to be provided, an obliquity sensor 11 is all arranged on each double cars 3, be used to monitor the levelness of double cars 3, when double cars 3 inclined degrees exceed 15 °, obliquity sensor 11 sends signal, elevator in-to-in elevator main controller is understood automatic analytic signal, adjusts the speed of quadruplet engine installation then, makes double cars 3 recovery levels.When double cars 3 risings run to straight rail and circular arc rail joint, can touch the contact switch 13 that is arranged on herein, this moment, the obliquity sensor 11 of double cars 3 was closed, elevator main controller is adjusted the speed of the quadruplet engine installation 6 of double cars 3, makes near two cover engine installations 6 of outer race track 2 with near two of inner race track 1 to overlap the motion of engine installations 6 constant angular velocities; When double cars 3 moves to next straight rail and circular arc rail joint with constant angular velocity, touch second contact switch 13 herein, obliquity sensor 11 is opened again, quadruplet engine installation 6 recovers with the speed motion, and double cars 3 was positioned at the straight rail of closed annular hoistway rail opposite side place and began to move downward this moment.Double cars 3 continues to move downward and can touch the 3rd contact switch 13, obliquity sensor 11 is closed once more, elevator main controller is adjusted the speed of the quadruplet engine installation 6 of double cars 3, makes near the two cover engine installations 6 of outer race track 2 and two cover engine installations, 6 constant angular velocities of close inner race track 1 and is moved into the circular arc rail; Touch the 4th contact switch 13 when double cars 3 turns over the circular arc rail, quadruplet engine installation 6 recovers to enter straight rail with the speed motion, realizes the whole circulation process.

Energy disperser on the double cars 3 links to each other with speed controller 10, electrical generator on the speed controller 10 and worm screw 9 coaxial rotation, worm screw 9 is rotated when accelerating, it is big that the electric current that corresponding electrical generator produces also becomes thereupon, this electric current is signal current, signal current enters galvo amplifier, by amplifier guiding acting electric current, the acting electric current excites electromagnet to produce electromagnetic attraction, and electromagnetic attraction drives the piston of the hydraulic ram of energy disperser, hydraulic oil promotes the brake clamp and clamps brake disc, and electric current is big more, and the electromagnetic attraction of generation is big more, and the brake clamp hold tight more, the braking force that produces is also just big more, thereby reaches the quick-acting fruits of braking control.

The motion process of 5 double cars 3 is identical, for no other reason than that in an elevator device a plurality of double cars 3 are arranged, so a displacement pickup that links to each other with elevator main controller 12 is all arranged on each car, be used to monitor the distance between adjacent two double cars 3, to guarantee the safety of passenger or article; When the distance between two double cars 3 up and down during less than the numerical value set, elevator main controller can two double cars of automatic compensation on the speed of engine installation 6, thereby control distance between them.When first double cars 3 rises to a certain position and has the passenger to need to stop down, displacement pickup 12 on second double cars 3 can in time detect the distance between two double cars 3, and feedback-related information is given elevator main controller, the speed of second double cars 3 of the elevator main controller corresponding adjustment of meeting, it is stopped, wait for slightly, avoid causing potential safety hazard.

Should be understood that this embodiment only to be used to the utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
