Climbing ladder apparatus in road is set, is used for stranded passenger's emergency escape.
The operation principle of circulation elevator of the present invention is：
Position induction device detects that car 30 is moved to when vertical guide 22 is moved to the boundary of cross slide way 21, control
Device processed controls one of hanging buckle 441 to be detached from hanging seat 442, while turntable 45 is controlled to rotate appropriate angle, in this way, car 30 is just
It is moved on cross slide way 21 under the guiding of guide groove 11；As car 30 is moved to the end of cross slide way 21, control
Device controls above-mentioned hanging buckle 441 to be fastened again with hanging seat 442, and control turntable 45 rotates back to origin-location, the idler wheel of car 30 again
31 are detached from guide groove 11, and car 30 continues to move in vertical guide 22.In the vertical and horizontal to during conversion of each car 30, all repeat
Above-mentioned switch operation.
If multiple passengers need to reach multiple hall doors 50, controller can calculate corresponding distance, be detected in level transducer
To after the reflection unit of respective hall door 50, traction machine 41 slows down and stops, and band-type brake action, car 30 is stopped at hall door 50, the Room
Door 50 is opened, and the seat 32 of the passenger is skidded off out of car 30, and passenger gets off from seat 32, meanwhile, the gravity-feed tank of seat 32
Device is answered to sense leaving for passenger, the service of the passenger terminates.If this layer also has the outer passenger for calling elevator together, which takes
Seat 32, seat 32 can be moved back in car 30, and hall door 50 is closed immediately, which can carry out selecting layer and other behaviour by executor
Make.
When all hall doors 50 are all closed, infrared protective device has not detected that passenger and carry-on articles exceed car 30
The signal of edge placement, controller send out permission run signal, and traction machine 41 starts, and driving traction chain 43 drives multiple cars
30 operations.
If certain layer is not purpose floor that passenger reaches or this layer has an outer passenger for calling elevator together, but seat at this time
32 all occupy, then level transducer is not carrying out flat bed hunting action, more horizontal seat 32 will not be released, only by raising
Sound device carries out the voice service of voice prompt waiting.
If certain layer have passenger carried out the outer passenger called together on elevator operation or some seat 32 by the layer set in order to
Purpose floor, controller according to current location calculate the distance away from this layer of shortest car 30, then drive car 30 run to
Purpose floor station cancels the registration of this purpose floor, then, repeats the above steps.
Relative to the prior art, circulation elevator of the invention realizes that multiple cars are being led by setting guide rail in hoistway
Cycle operation on rail, had not only improved the carrying capacity of elevator, but also improved the utilization rate to relatively narrow hoistway space, together
When can cut the input of counterweight, reduce cost；In addition, the circulation elevator of the present invention in car by setting what is slided
Seat 32 can provide the seating service of hommization for passenger, enrich usage experience of the passenger to elevator.Simultaneously as the Room
Men Keyu seats match, and seat stretches out hall door and opens, and have prevented the security risk that personnel fall well, the size of hall door also can be substantially
Reduce, saved elevator cost, and the opening and closing of hall door, can have been controlled, also ad save by the stretching power of seat
The part of the special door motor of car.The circulation elevator of the present invention is with carrying capacity is strong, space utilization rate is high, at low cost, human nature
The advantages that change.
Embodiment described above only expresses the several embodiments of the present invention, and description is more specific and detailed, but simultaneously
It cannot therefore be construed as limiting the scope of the patent.It should be pointed out that those of ordinary skill in the art are come
It says, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the protection of the present invention
Range.
