Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is front view of the present utility model;
Fig. 2 is birds-eye view of the present utility model;
Fig. 3, Fig. 4 are work scheme drawings of the present utility model.
The specific embodiment
With reference to Fig. 1, Fig. 2, a kind of counterweightless device formula elevator, the hoistway 1 that comprises the terraced lifting of powering, be provided with first car 2 and second car 3 in the described hoistway 1, be provided with compound wound machine 4 directly between described first car 2 and second car 3, wherein said compound wound machine 4 is provided with traction after-combustion rope sheave 41 and guiding after-combustion rope sheave 42, wherein traction after-combustion rope sheave 41 provides active force, guiding after-combustion rope sheave 42 is then as flower wheel, it is movable and disperse the stressed effect of traction after-combustion rope sheave 41 to play guiding elevator ropes 51, and this has vital function for this elevator that counterweight is not set.The madial wall both sides of described hoistway 1 are provided with elevator ropes tapered sleeve 5, described elevator ropes tapered sleeve 5, first car 2, compound wound machine 4 and second car 3 are connected in turn by an elevator ropes 51, and wherein the two ends of elevator ropes 51 are connected with the elevator ropes tapered sleeve 5 of both sides respectively.Described first car 2 and second car, 3 upper ends are respectively arranged with the single winding apparatus 6 of track adjusting wheel, and the single winding apparatus 6 of this track adjusting wheel is provided with left and right two lists at least around track adjusting wheel 61.On the whole, elevator ropes tapered sleeve 5 and the compound wound machine 4 of hoistway 1 both sides belong to attachment point, 3 of first car 2 and second cars can be along hoistway 1 oscilaltions, and the single winding apparatus 6 of track adjusting wheel also moves along with first car 2 and second car 3, wherein elevator ropes 51 is under the effect of car, and two ends all are in the pulling force of equal size.Elevator ropes 51 is being to adopt the after-combustion mode to improve the relative friction forces of compound wound machine 4 and elevator ropes 51 through compound wound machine 4 places, this is for this elevator that counterweight is not set, can play important stabilization, the wherein after-combustion number of turns can be according to actual flexible design.Because not having counterweight occupy-place, the direction of opening the door of first car 2 and second car 3 can be in the same way, in opposite directions even vertical setting, does not all influence operation.
The lower end of described first car 2 and second car 3 is connected with compensation rope 7, described hoistway bottom 1 is provided with the compensation rope guide piece 71 for guiding compensation rope 7, this compensation rope guide piece 71 is provided with left and right two track adjusting wheels 72 at least, and the two ends of described compensation rope 7 are connected with the bottom of first car 2 and second car 3 respectively.Because elevator is in the whole service process, the length of elevator ropes 51 is constant substantially, therefore the length of compensation rope 7 also is relative fixed, the length of the local elevator ropes 51 that promotes relates to the length of local equalize's rope 7, be enough to guarantee the elevator reliability service, and compensation rope guide piece 71 can guarantee that the tension force size and Orientation that compensates rope 7 keeps enough stable.
Be provided with overspeed protection device 8 between described first car 2, second car 3 and the hoistway 1, this overspeed protection device 8 comprises the safety clamp that can clamp cage guide and the signal head that is used for receiving compound wound machine 4 instructions.When elevator overspeed, overspeed protection device 8 first teletype commands are by the disconnected safety return circuit switch of motor, do not have the operation of electricity power supply ladder after, be clipped in and do not allow car continue toward descending on the guide rail if just control safety tongs when still exceeding the speed limit.
When real work, with reference to Fig. 3, when the 2 rising carryings of needs first car, the traction after-combustion rope sheave 41 beginning clickwises of compound wound machine 4 drive first car 2 and rise, and second car 3 also descends thereupon, be with other passenger to go down, namely first car 2 and second car 3 are shared out the work and help one another and are carried the passenger origin both direction respectively; With reference to Fig. 4, when needs first car 2 is being with the passenger to go down, the running of traction after-combustion rope sheave 41 conter clockwises, second car 3 then can be with other passenger to get on.So first car 2 and second car 3 not only form the combination of relative equilibrium, and can share out the work and help one another, improve the efficient of elevator.
According to above-mentioned principle, the utility model can also carry out suitable change and modification to above-mentioned embodiment, and for example the elevator ropes 51 by many connects in the same way, and the fine setting of compound wound machine 4 installation sites is like that.Therefore, the specific embodiment that discloses and describe above the utility model is not limited to also should fall in the protection domain of claim of the present utility model modifications and changes more of the present utility model.
Facts have proved, this elevator passes through with first car 2 and 3 two car Compositional balances of second car suspension system apparatus, realized only just can controlling the effect that two cars move up and down with a compound wound machine 4, a motor and a cover control system have been saved, saved the shared space of elevator greatly, and saved manufacturing and maintenance cost, easy to utilize.
