Abstract
Counterweight-free double elevators dragged with one system and running from opposite directions comprises an elevator drag system. A drag rope is winded on a drag wheel and a guide wheel in sequence and two ends of the drag rope are fixedly connected with a machine room. The tops of a first lift car and a second lift car are respectively provided with a first movable pulley and a second movable pulley, and the drag rope is winded on the first movable pulley and the second movable pulley to respectively drag the first lift car and the second lift car vertically. According to the counterweight-free double elevators dragged with one system and running from the opposite directions, the own weight and load of the first lift car and the own weight and load of the second lift car serve as mutual counterweights, and therefore the two lift cars can go vertically, empty transportation is reduced, elevator transportation abilities are enhanced while fabricating cost and operation cost of the elevators selves are lowered, and space is saved. The counterweight-free double elevators dragged with one system and running from the opposite directions can be widely used for places with high people flow rates and frequent requirements of elevators, wherein the places can be shopping malls, hotels, dwelling houses, hospitals, and the like.
Description
Technical field
The utility model discloses a kind of elevator, particularly a kind ofly utilize two cars to split elevator as the counterweightless one drag two of counterweight each other.
Background technology
Existing elevator device comprises elevator cage, traction system and to pouring weight; In succession respectively car and of hoist ropes two ends to pouring weight; Be wrapped on traction sheave and the track adjusting wheel, hoisting motor rotates through driving traction sheave after the retarder speed change, leans on hoist ropes and the fricative tractive force of traction sheave; Realize car and, reach the transportation purpose the dipping and heaving of pouring weight.
Owing to must hold the conventional room for promotion to pouring weight, so hoist-hole need design extra counterweight track, reduced other usage spaces of building in the existing elevator device; On the other hand, reach balance to greatest extent for reaching in the different loads operating mode, how the weight of counterweight no matter how load changes; Remain constantly, usually, add that half weight of maximum load is formed by the weight of car system itself; Make the Heavy Weight of counterweight itself like this, cost is high; Its three, be used to guide the guide rail of counterweight and assemble the involved installation of these parts, artificial and time cost related.Particularly in the market, hotel, dwelling house and these flows of the people of hospital are big; Elevator uses frequent place; Must install the demand that the multi-section elevator could solve people, and an elevator uses the independent system of a cover, so just caused the waste of elevator human and material resources resources greatly.
The utility model content
The purpose of the utility model provides two cars of a kind of employing and splits elevator as the counterweightless one drag two of counterweight each other; In order to solve the problem that the independent counterweight system that is provided with of existing elevator device takies space, can make market, hotel and hospital etc. to the frequent reasonable and energy-conservation operation elevator in place that uses of elevator.
The utility model adopts following technical scheme to realize: a kind of counterweightless one drag two is split elevator; The traction system that comprises elevator; Hoist ropes one end of said traction system connects first car; Hoist ropes is wrapped on traction sheave and the track adjusting wheel successively, and the other end of said hoist ropes is connected with second car as first car counterweight, and said traction system drags first car and second cage operation simultaneously.
The top of said first car and second car is set with first movable pulley and second movable pulley respectively, and the two ends captive joint of said hoist ropes, hoist ropes are wrapped on first movable pulley and second movable pulley and draw respectively about first car and second car.Adopt about the movable pulley traction car,, improved about one times of the power of load-carrying capacity and the hoisting motor of hoist ropes, improved the safety factor of elevator greatly though reduced the running velocity of elevator.
Adopt the counterweightless one drag two of the utility model to split elevator; Weight through first car and second car itself and load thereof are as mutual counterweight; Only need a cover towing machine system, a cover power-supply system, a cover control system both can control two lift cars about, realize the function of two elevators, guarantees that two cars have on having under; Reduced air transport; Reduced the cost and the operating cost of elevator itself when having increased the transport power of elevator, two cars do not need to be provided with separately pouring weight and track thereof in addition simultaneously, have enlarged other usage spaces of building.
From the above mentioned; A kind of counterweightless one drag two that the utility model provided split elevator have energy-conservation, cost is low, advantage such as safe; Elevator device need not be provided with independent counterweight system; Further discharged other spaces of building, can be adaptable across the market, flows of the people such as hotel and hospital are big and elevator is used frequent place.
Description of drawings
Fig. 1 is the structural representation sketch of the utility model.
Label among the figure: 1-traction sheave, 2-track adjusting wheel, 3-second movable pulley, 4-second car, 5-hoist ropes, 6-first car, 7-first movable pulley, 8-machine room.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
Embodiment:
Referring to Fig. 1; A kind of counterweightless one drag two is split elevator; Its traction system comprises traction sheave 1, track adjusting wheel 2 and hoist ropes 5; Hoist ropes 5 then is wrapped on traction sheave 1 and the track adjusting wheel 2 successively, and hoist ropes 5 two ends are twined first movable pulley 7 that is arranged on first car 6 and second car 4 and second movable pulley 3 respectively in order to draw first car 6 and second car about in the of 4, and its fag end is fixedly set in machine room 8.
When first car 6 is during in low layer, 4 of second cars are positioned at high level, and when first car 6 was up, second car 4 and load-carrying thereof were then descending as the counterweight of first car 6; Vice versa.
Claims (2)
1. a counterweightless one drag two is split elevator; Include the traction system of elevator; Hoist ropes one end of said traction system connects first car; Hoist ropes is wrapped on traction sheave and the track adjusting wheel successively, it is characterized in that: the other end of said hoist ropes is connected with second car as first car counterweight, and said traction system drags first car and second cage operation simultaneously.
2. a kind of counterweightless one drag two according to claim 1 is split elevator; It is characterized in that: the top of said first car and second car is set with first movable pulley and second movable pulley respectively; The two ends captive joint machine room of said hoist ropes, hoist ropes is wrapped on first movable pulley and second movable pulley and draws respectively about first car and second car.
