Description
Affiliated technical field
The utility model relates to a kind of rack-and-gear transmission adjustable frequency motor cage lifter of saving oneself that has a power failure, and belongs to the elevator technology field.
Background technology
At present, its running part of known elevator mostly is rope traction or spiral two big classes, can't save oneself when the former has a power failure, the latter can save oneself, and make the installation vertical shaft and want three above screw racks at least, otherwise squareness, right alignment be difficult to guarantee, more than two kinds of equipment manufacturing cost height, install comparatively complicated.
Summary of the invention
In order to overcome above-mentioned deficiency, the utility model has been developed a kind of rack-and-gear transmission adjustable frequency motor cage lifter of saving oneself that has a power failure, this elevator is by gear, vertical tooth rack, I-beam section, worm decelerating machine, adjustable frequency motor, drg, elevator car, counterbalanced weight, the lifting flexible cable, the PLC control setup is formed.Gear, worm decelerating machine, adjustable frequency motor, drg, safety tongs and elevator car are one, and the wheel and rack engagement moves up and down.Cable, PLC control box are located at zero rice layer, and cable is introduced elevator car and each layer doorway by control box, removes lift facility from and is located at tall building, building highest point, has reduced civil engineering costs.
The technical scheme that its technical matters that solves the utility model adopts is: on tall building, building exterior wall of elevator is installed or pre-buried steel part arranged in the vertical shaft, I-beam section or vertical being welded on the pre-buried steel part that designs of channel-section steel, fix tooth bar in the inboard or the outside of two I-beam sections with fastener by design size.The output gear of (little tonnage can replace I-beam section with channel-section steel) two worm decelerating machines meshes with two vertical tooth racks respectively, under the cooperation of counterbalanced weight, adjustable frequency motor drives worm decelerating machine and carries out dipping and heaving, carry moving envelope synchronization action, below worm decelerating machine, be provided with support wheel and safety tongs, the elevator car top is provided with take-up pulley, and the counterbalanced weight pull line guarantees the stable equilibrium operation of envelope upper and lower, left and right.
The beneficial effects of the utility model are: be provided with the door of saving oneself on the floor of elevator car, the passenger can open the door of saving oneself during power failure, operational brake on the other hand, and the rotating joint wheel of saving oneself can drop to the exit on the other hand; Adopt this technical scheme to cut a large amount of steel rope consumptions, reduced cost; The fast jogging speed of adjustable frequency motor automatic guidance worm decelerating machine adds system's control and the reductor self-locking of PLC, the phenomenon that exceeds the speed limit can not occur; Electrical control gear all is located at zero rice layer, and maintenance is convenient; So but same specification elevator cost-cutting is more than 20%.It is simple in structure, and every technical performance all reaches the national requirements standard.
