Description
Technical field
This utility model belongs to box elevators field.
Background technology
Cage type elevator is a kind of vertical conveyor being power with motor, equipped with box like gondola, takes advantage of people or carrying goods for tier building.In people's life, conventional cage type elevator has a car, and this car is mainly made up of traction machine (winch), guide rail, counterweight, safety device (such as limiter of speed, safety tongs and buffer etc.), signal manipulation system, car and hall door etc..These parts are separately mounted in hoistway and the machine room of building.In succession car and counterweight respectively in hoist ropes two ends, being wrapped on traction sheave and directive wheel, hoisting motor is by driving traction sheave to rotate after decelerator speed change, by hoist ropes and the fricative pull strength of traction sheave, realize the elevating movement of car and counterweight, reach transport purpose.But, when utilizing hoist ropes traction car motion, once hoist ropes ruptures, then car will directly fall, and causes serious consequence.Existing elevator is this kind of form, can not ensure the safety of elevator user.
Therefore a kind of publication number that arisen at the historic moment is CN1966380A, name is called the elevator of " ball screw is elevator controlling structure ", this kind of elevator utilizes the rotary principle of screw rod and nut, make elevator raise or decline, it is to avoid the potential danger of hoist ropes, but when practical application, the screw rod that this elevator structure adopts, must have the length meeting story height, but with current technology level, the screw rod of this length is difficult to obtain.
In sum, existing elevator structure is single, and all has very big defective.
Utility model content
This utility model is single in order to solve existing elevator structure, and all has the problem of very big defective, a kind of worm drive formula emergency staircase of existing offer.
Worm drive formula emergency staircase, it includes: motor 1, multiple nut 2, drive link 3, panel 5 and car 6；
Car 6 is internal is provided with dividing plate, and this dividing plate is divided into equipment cavity and carrying chamber by internal for car 6, and motor 1, multiple nut 2 and drive link 3 are respectively positioned on inside equipment cavity, and panel 5 is positioned at carrying intracavity portion, equipment cavity and elevator wall 4 just to side be open design；
Multiple nuts 2 are coaxially disposed from top to bottom, and motor 1 drives multiple nut 2 synchronous rotary by drive link 3 simultaneously；
The surface of elevator wall 4 is provided with oblique screw thread, and the external screw thread of multiple nuts 2 all with the threaded engagement on elevator wall 4 surface, and can move up and down along elevator wall 4 when multiple nuts 2 rotate；
The signal output part that drives of panel 5 connects the driving signal input of motor 1, and panel 5 is for drive motor 1 forward or reverse.
Worm drive formula emergency staircase described in the utility model, the mode adopting nut and flat thread transmission drives lift car to move up and down, thoroughly instead of the mode by hoist ropes with traction sheave traction car in prior art, be inherently eliminated the hidden danger that hoist ropes breaks.And simplifying counterweight part, structure is simpler.Simultaneously as there is no counterweight so that space availability ratio is greatly improved, add economy.
Accompanying drawing explanation
Fig. 1 is the structural representation of the worm drive formula emergency staircase described in detailed description of the invention one；
Fig. 2 is the A portion enlarged drawing of Fig. 1.
Detailed description of the invention
Detailed description of the invention one: illustrate present embodiment referring to figs. 1 through Fig. 2, the worm drive formula emergency staircase described in present embodiment, it includes: motor 1, multiple nut 2, drive link 3, panel 5 and car 6；
Car 6 is internal is provided with dividing plate, and this dividing plate is divided into equipment cavity and carrying chamber by internal for car 6, and motor 1, multiple nut 2 and drive link 3 are respectively positioned on inside equipment cavity, and panel 5 is positioned at carrying intracavity portion, equipment cavity and elevator wall 4 just to side be open design；
Multiple nuts 2 are coaxially disposed from top to bottom, and motor 1 drives multiple nut 2 synchronous rotary by drive link 3 simultaneously；
The surface of elevator wall 4 is provided with oblique screw thread, and the external screw thread of multiple nuts 2 all with the threaded engagement on elevator wall 4 surface, and can move up and down along elevator wall 4 when multiple nuts 2 rotate；
The signal output part that drives of panel 5 connects the driving signal input of motor 1, and panel 5 is for drive motor 1 forward or reverse.
In present embodiment, take full advantage of the existing resource of elevator well channel wall as elevator motion track, the multiple nuts 2 being fixed in car are meshed with elevator wall 4, then multiple nut 2 synchronous axial system is driven, when multiple nuts 2 rotate, multiple nuts 2 just can move up and down along elevator wall 4 on elevator wall 4, and then has driven car to move up and down.In present embodiment, multiple nuts 2 are meshed with elevator wall 4 simultaneously, and this structure is more safe and reliable compared to the mode that messenger suspension dragged by existing elevator, has been inherently eliminated the hidden danger that hoist ropes breaks.And make full use of the structure of elevator hoistways, decrease the cost increasing screw rod so that the elevator of present embodiment is more easy to realization, and is greatly saved equipment cost.
The distance moved due to nut 2 for every revolution is fixing, when elevator user needs mobile floor, drives nut 2 to rotate the corresponding number of turns, it becomes possible to reach relevant position.
Elevator user is carried out subregion with elevator machinery part by arranging of dividing plate, thus preventing artificial destruction lift facility, affects passenger, outside concurrent business when being also prevented from equipment work.
Multiple nuts 2 together move and ensure that being clamped on elevator wall 4 of car, and alleviate nut 2 burden.
Present embodiment can be programmed realizing by the programmable logic controller such as PLC, single-chip microcomputer, and is simple collection and judgement, more easily realizes.Utilizing motor to drive nut to rotate, be namely capable of elevator ascending motion, the rotating cycle k of motor is as follows:
Wherein, N is that elevator is currently located the floor number of plies, and M is the target floor of lifter number of plies, and X is the height value between every floor, and Y is that nut 2 rotates a circle the distance value risen.
The rotating cycle formula of the motor proposed in present embodiment is simple, it is easier in the controller by programming realization, alleviate manufacture difficulty.
Detailed description of the invention two: present embodiment is that the worm drive formula emergency staircase described in detailed description of the invention one is described further, and in present embodiment, panel 5 is fixed on above carrying cavity wall, and this panel 5 is provided with elevator number of plies button.
The restriction of this position is prevented from child or other passengers touch by mistake, causes device damage.
Detailed description of the invention three: present embodiment is that the worm drive formula emergency staircase described in detailed description of the invention one, two or three is described further, and in present embodiment, it also includes speech ciphering equipment, and this speech ciphering equipment is used for reporting the elevator parking number of plies.
Worm drive formula emergency staircase described in the utility model is when reality is implemented, for car bearing capacity and security consideration, on two sidewalls that elevator wall 4 is facing each other, it is equipped with oblique screw thread under actual performance, and drive link 3 and nut are set at car both sides specular.
Detailed description of the invention four: present embodiment is that the worm drive formula emergency staircase described in detailed description of the invention one, two, three or four is described further, and in present embodiment, it also includes steady arm, and this steady arm runs through cage vertical and is fixed in elevator hoistways.
