Fig. 2 is the skiagraph of the elevator without machine room of the embodiment of the present invention 1 to 1 wiring ratio.
The specific embodiment
Below in conjunction with accompanying drawing, embodiments of the invention are elaborated: the present embodiment is implemented under take technical solution of the present invention as prerequisite, provided detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
As depicted in figs. 1 and 2, on the both sides well enclosure 1a of hoistway 1 Width and 1b, be provided with car guide rail 3a and 3b.Car guide rail 3a and 3b lead to the motion of car frame 10, make car frame 10 carry car 11 interior along plumb bob vertical direction free lifting at hoistway 1.
Hoistway 1 depth direction rear side is provided with counter weight guide track 6a and 6b, in the gap between car frame 10 and well enclosure 1c.Counter weight guide track 6a and 6b lead to the motion of counterweight 12, make counterweight 12 interior along plumb bob vertical direction up-and-down movement at hoistway 1.
Car guide rail 3a top is provided with the first diversion sheave 4a, and car guide rail 3b top is provided with the second diversion sheave 4b.And then the axis of the first diversion sheave 4a and the second diversion sheave 4b overlaps mutually.Counter weight guide track 6a top is provided with the first traction sheave 7a, and counter weight guide track 6b top is provided with the second traction sheave 7b.And then the axis of the first traction sheave 7a and the second traction sheave 7b overlaps mutually.
The axis of the first traction sheave 7a and the first diversion sheave 4a is parallel to each other, and grooving faces mutually.And then the grooving number of the first traction sheave 7a and the first diversion sheave 4a is the half of hoist ropes sum.The axis of the second traction sheave 7b and the second diversion sheave 4b is parallel to each other, and grooving faces mutually.And then the grooving number of the second traction sheave 7b and the second diversion sheave 4b is the half of hoist ropes sum.
When wiring, half hoist ropes 5a is connected with counterweight 12 after the first traction sheave 7a through the first diversion sheave 4a successively by the first fag end assembly 2a.Remaining half hoist ropes 5b is connected with counterweight 12 after the second traction sheave 7b through the second diversion sheave 4b successively by the second fag end assembly 2b.
According to above-mentioned embodiment, realize the elevator without machine room of 1:1 wiring ratio with simple structure.The minimizing of track adjusting wheel, can significantly improve life-span of steel rope.In addition, because traction sheave and track adjusting wheel are all outside car projecting plane, do not increase the requirement to well headroom spatial altitude, effectively reduce building cost.
