And; As main hoist cable 5; If use the hoist cable that applied resin or, then can improve bendability, make it possible to very easily set the diameter of drive pulley 9 for 29 times smaller or equal to main hoist cable 5 with the hoist cable as main component such as aromatic polyamide resin.
Next with reference to Fig. 3 and Fig. 4 another embodiment is described.In Fig. 3; Lift car side master hoist cable connecting element 3 is arranged on the top of the side direction of lift car 1; Main hoist cable 5 is constituted as from said lift car side master hoist cable connecting element 3 and extends towards the below; Use rope sheave 7b from lift car with another lift car of rope sheave 7a extend past, the extend past lift car side that is arranged on lift car 1 top turns to rope sheave 8a, 8b then, extends towards the below once more afterwards and arrives drive pulley 9; After this; This main hoist cable 5 reel on this drive pulley 9 about 180 degree backs towards above the balance heavy side turn to rope sheave 11 to extend, turn to rope sheave 11 backs to extend the balance heavy side master hoist cable connecting element 14 above arriving at last with rope sheave 12a, 12b towards the counterbalanced weight on the counterbalanced weight 2 that is arranged on the below through the balance heavy side.
The difference of Fig. 4 and Fig. 2 is; Turn to rope sheave 8a, 8b through between lift car 1 and drive pulley 9, the lift car side being set; Slim winch 10A is set below hoist trunk; Between drive pulley 9 and counterbalanced weight 2, the balance heavy side is set and turns to rope sheave 11, and 2 rope sheave 12a, 12b are set on rope sheave, thereby counterbalanced weight 2 has been arranged on the rear of lift car 1 at counterbalanced weight.
Through having aforesaid structure; The degree of freedom that is provided with of counterbalanced weight 2 increases; Can improve the efficient that is provided with in hoist trunk; But compare with above-mentioned embodiment illustrated in figures 1 and 2,, make the problems such as service life of bending resistance and main hoist cable become more remarkable because the quantity of rope sheave increases.Therefore; In Fig. 3 and embodiment shown in Figure 4; Other that pass to all rope sheave 7a, 7b, 12a, 12b and all of said lift car of major general 1 and counterbalanced weight 2 or surpass half turn to rope sheave 8a, 8b, 11 diameter to set the diameter greater than drive pulley for, then can obtain the effect same with embodiment illustrated in figures 1 and 2.
Followingly another embodiment is described with reference to Fig. 5 and Fig. 6.In Fig. 5; Main hoist cable 5 is constituted as from the lift car master hoist cable connecting element 3 extend past master hoist cables that are arranged on lift car 1 ground plate portion and returns pulley 4 and extend towards the top; Use rope sheave 7a from the lift car that turns to rope sheave 6a, 6b extend past lift car 1 top of elevator car upper; Turn to rope sheave 8a to extend from the lift car side that is arranged on lift car 1 top afterwards towards drive pulley 9; After this; This main hoist cable 5 is wound on the drive pulley, and extend past be arranged on counterbalanced weight on the counterbalanced weight 2 of below with rope sheave 12a after once more towards 13 extensions of the balance heavy side rope sheave on hoist trunk top, arrive the balance heavy side master hoist cable connecting element 14 of counterbalanced weight 2 at last.
In Fig. 4, the method for winding that main hoist cable adopted 2: 1 is reeled, and in contrast to this, in Fig. 6, the method for winding that main hoist cable adopted 3: 1 is reeled, and body asthenic winch 10 is arranged on the top of lift car 1, is very different with Fig. 4 on this point.Through adopting said structure, under the diameter of drive pulley 9 situation identical, still can reduce drive torque and lock torque etc. with Fig. 4, therefore can further realize the miniaturization of winch.As stated, though elevator has various structures, no matter be any structure, through setting the diameter of the rope sheave beyond the drive pulley for diameter, all can obtain the effect same with previous embodiment greater than drive pulley with above-mentioned condition.
