Description
Technical field
The present invention relates to a kind of high-rise track elevator, relate in particular to a kind of rope-free and falling-prevention freestanding elevator.
Background technology
Traditional elevator is the rope elevator, and based on cord drive, an end of rope connects the car of elevator, and the other end connects trailer coupling.The drawback of the maximum of rope elevator is exactly the restriction that is subjected to height, because the weight of steel wire cable self is very heavy, in case building reaches certain height then the rope elevator just is difficult to meet the demands: the weight of rope elevator self will increase with the increase of height, and rope stressed has certain limit.The weight of its delivery also can be had a greatly reduced quality when overcoming own wt, and also will reduce greatly service life, and safety is difficult to be protected.Rope elevator faults rate height, the phenomenon that the card machine occurs even fall when being everlasting operation or power failure suddenly.Along with being extensive use of of rope elevator, the accident of rope elevator also takes place again and again.Though the rope elevator is constantly improving and perfect, effect be not clearly and complicated in mechanical structure be not easy to M R.
In sum, the weak point of rope elevator is that safety and smoothness are not high, and service life is short, and complex structure is not easy to M R, the cost height.
Summary of the invention
Purpose of the present invention just is to overcome the shortcoming and defect of existing rope elevator, and a kind of rope-free and falling-prevention freestanding elevator is provided.The present invention be a kind of safe and practical, operate steadily, long service life, simple in structure and cheap elevator.
The object of the present invention is achieved like this:
The present invention includes car, be provided with trailer coupling and gear guide groove;
Top at car is provided with trailer coupling, and trailer coupling is scroll-up/down in the gear guide groove.
The present invention has following advantage and good effect:
1, owing to be wireless traction, be provided with speed-limit drive gear and constant speed device again, make safely, smoothness is good, long service life;
2, be not subjected to limitation in height, solved the restriction of traditional elevator height;
3, full mechanical, cheap, convenient maintenance; Operating cost is low;
4, be applicable to all vertical lifts.

The specific embodiment
Describe in detail below in conjunction with drawings and Examples:
One, overall
As Fig. 1, the present invention includes car 300, be provided with trailer coupling 100 and gear guide groove 200;
Be provided with trailer coupling 100 at the top of car 300, trailer coupling 100 is scroll-up/down in gear guide groove 200.
Two, function block
1, trailer coupling 100
As Fig. 2, described trailer coupling 100 comprises front and back bonded assembly motor 110, reducing gear 120, transmission shaft 130, power-transfer clutch 140, helical tooth 150, transmission gear 160, traction gear 170, speed-limit drive gear 180 and constant speed device 190 successively.
Described speed-limit drive gear 180 is to be connected with miniature gears 183 on its axle, miniature gears 183 and separates straight trough 182 in clutch gear 181 mesh, clutch gear 181 meshes with traction gear 170 again;
As Fig. 3 .1,3.2, described constant speed device 190 comprises inertia opening and closing page or leaf 191, adjustment screw 192, gravity lifting friction drum 193, page or leaf axle 194, fixed friction tube 195 and fluted disc axle 196;
Be provided with fluted disc axle 196 in the centre of fixed friction tube 195, above the axle of fluted disc axle 196, be with gravity lifting friction drum 193; On the dish of fluted disc axle 196 bottoms, be fixed with inertia opening and closing page or leaf 191 by page or leaf axle 194; Top at inertia opening and closing page or leaf 191 is provided with adjustment screw 192.
2, other function block and components and parts thereof are part commonly used.
Three, principle of work of the present invention
The present invention rotates by motor 110 and drives reducing gear 120, transmission shaft 130, power-transfer clutch 140, helical tooth 150, transmission gear 160 successively until traction gear 170, because traction gear 170 scroll-up/down gear guide groove 200 in, thus make with trailer coupling 100 and with 300 oscilaltions of trailer coupling 100 bonded assembly cars; Rotate counterclockwise as traction gear 170, car 300 rises; Clockwise rotate as traction gear 170, car 300 descends.
When traction gear 170 rotates counterclockwise, drive clutch gear 181 and in separating straight trough 182, promote, make 183 engagements of clutch gear 181 discord miniature gearss, promptly speed-limit drive gear 180 and constant speed device 190 are not worked;
When traction gear 170 clockwise rotates, drive clutch gear 181 and in straight trough 182, descend, make clutch gear 181 and miniature gears 183 engagements, i.e. speed- limit drive gear 180 and 190 work of constant speed device;
When speed-limit drive gear 180 normal operation, as Fig. 3 .1, fluted disc axle 196 rotates inertia opening and closing page or leaf 191 is not opened fully, and gravity lifting friction drum 193 does not contact with fixed friction tube 195, thereby does not play the speed limit effect;
When speed-limit drive gear 180 rotations are too fast, as Fig. 3 .2, fluted disc axle 196 twirl make inertia opening and closing page or leaf 191 be subjected to centrifugal action and open fully, cause the top of inertia opening and closing page or leaf 191 and the friction between fixed friction tube 195 sidewalls to strengthen on the one hand, play the speed limit effect; Cause gravity lifting friction drum 193 to rise on the other hand and also contact, increase the friction force between gravity lifting friction drum 193 and the fixed friction tube 195, also play the speed limit effect with fixed friction tube 195.
This shows that the effect of constant speed device 190 is that car 300 constant speed are steadily fallen, and prevents the phenomenon of falling.
The end of transmission shaft 130 is with helical tooth 150 and transmission gear 160 ingears.Otherwise its advantage of this connection mode is to have only the transmission shaft 130 can be to transmission gear 160 transmissions and not so.So just ensured that elevator car 300 when sudden power or motor 110 break down can not fall, and stopped, guaranteed the safety of the person in the original place.The people that be trapped in car 300 the insides this moment can will be arranged on the switch opens of the power-transfer clutch 140 of car 300 the insides, transmission shaft 130 and driving device and motor 110 are separated, one deck can directly be fallen in 300 downward constant speed whereabouts under the control of constant speed device 190 of car; Also manually the switch of control clutch 140 guarantees the safety of the person to the position of safety door.
The power supply of motor 110 is to contact with the horizontal path track that is arranged on gear guide groove 200 limits by two junction poles, sliding and running in the above, and its principle of work is the same with rail electric car.
