The specific embodiment
Below in conjunction with accompanying drawing and by the specific embodiment, further illustrate technical scheme of the present invention.
As Figure 1-Figure 5, wherein, Fig. 4 has illustrated top layer planar view, Fig. 5 to illustrate hoistway planar view.The hoistway arrangement structure of a kind of machine-roomless lift that present embodiment provides, it comprises car 1, be arranged on the sedan-chair return pulley 5 of car 1 upper bottom portion, be arranged on towing machine 2 on the first bearing beam 10, be arranged on traction sheave 4 on towing machine 2, be wound in hoist ropes 3, counterweight 6 on traction sheave 4, be arranged on counterweight 6 tops and be connected with counterweight 6 to roller 7, to heavy side rope hitch plate 8 and cage side rope hitch plate 9 and control housing 13, car 1 is 2:1 with the traction ratio of counterweight 6.
Control housing 13 is located on the antetheca of elevator hoistways, for controlling the operation up and down of elevator.Car 1 slides up and down operation in car guide rail 16.The outer wall of car 1 is provided with velocity limiter 14, because velocity limiter 14 is stressed less, makes car guide rail 16 can not bear too large cantilever force, when guaranteeing elevator operational effect, has also saved hoistway space.
Towing machine 2 is internal rotor towing machine, and the diameter of traction sheave 4 is 320nm, effectively reduces the oad of towing machine, by rational layout, takes full advantage of hoistway space, has improved the traveling comfort of elevator, has increased the technical advantage of elevator.Counterweight 6 adopts and mixes pouring weight, has cancelled the use of iron to pouring weight, reduces energy consumption, is beneficial to environmental protection, has reduced the operating cost of elevator.
The first bearing beam 10 that supports towing machine 2 is horizontally disposed with along the fore-and-aft direction of elevator hoistways and a side of close elevator hoistways, and counterweight 6 is positioned at the below of the first bearing beam 10 and a side setting of close elevator hoistways, and car 1 is near the opposite side setting of elevator hoistways.In addition, counterweight 6 slides up and down operation in counter weight guide track 15, and counter weight guide track 15 is arranged on rail brackets 17.
Heavy side rope hitch plate 8 is located on the first bearing beam 10, and cage side rope hitch plate 9 is located on the second bearing beam 11, between the gate of car 1 and sedan-chair return pulley 5, is provided with car vertical beam 12, and car vertical beam 12 is positioned at a side of car 1, for supporting car 1.
One end of hoist ropes 3 is fixed on heavy side rope hitch plate 8, and one end of hoist ropes 3 is first walked around downwards roller 7, then upwards walks around traction sheave 4, then walks around at least two sedan-chair return pulleys 5 downwards, and the other end of last hoist ropes 3 is fixed on cage side rope hitch plate 9.
In machine-roomless lift operational process, when control housing 13 control traction sheaves 4 clockwise rotate, cage side hoist ropes 3 shortens, and drives lift car 1 upward movement simultaneously, and counterweight 6 moves downward, and realizes the rising of elevator.Otherwise, when control housing 13 control traction sheaves 4 rotate counterclockwise, heavy side hoist ropes 3 is shortened, drive counterweight 6 upward movements, 1 of car moves downward, and finally realizes the decline of elevator.
The present invention is also provided with the balanced compensated chain for balance car weight, makes between balance car and counterweight within weight difference keeps limit, to guarantee that the traction-driven of elevator is normal.
The above combination specific embodiment has been described know-why of the present invention.These are described is in order to explain principle of the present invention, and can not be interpreted as by any way limiting the scope of the invention.Explanation based on herein, those skilled in the art does not need to pay performing creative labour can associate other specific embodiment of the present invention, and these modes all will fall within the scope of protection of the present invention.
