The example 1 of tractor elevator device of the present invention is described with Fig. 1.As shown in Figure 1, tractor elevator device of the present invention is provided with track adjusting wheel 1a, 1b under car 1, the car, cage side reversion wheel 2, rope 3, bont 4, drives rope sheave 4a, balance block side reversion wheel 5, balance block 6, balance block hanging wheel 6a.
Bont 4 is configured in than the high position, orlop ground in the access trunk.Therefore, even water flows in the access trunk, also the water that overflows from ground a heatable brick bed portion spread to the outside from orlop ground, so bont 4 can not had by water logging.
Take turns 2, hang car by the cage side reversion that is set at Guide vehicle 1a, 1b and access trunk top with the rope of reeling.And then rope 3 is suspended on the balance block hanging wheel 6a of balance block 6 by the balance block side reversion wheel 5 that is arranged on the access trunk top from the bont 4 that is arranged on the position higher than orlop ground.
When stretching like this, the life-span of rope 3 depends on the number of bends of each reversion wheel and imposes on the shape of the rope ditch of each reversion wheel.Generally speaking, the rope groove on the driving rope sheave 4a of bont 4 adopts V-arrangement, undercut type (ァ Application ダ one カ ッ ト) in order to improve friction force, compares with other circular troughs that are applied to the reversion wheel, and there is the tendency of shortening 1/2～1/3 in the life-span of rope.
In addition, very big for the influence of rope 3 bendings, rope 3 was crooked opposite when each reversion wheel passed through, and the direction of flexure stress repeats counter-rotating, so rope 3 produces fatigue, the lost of life.Thereby, do not take turns for the part that makes hanging on of rope 3 drive rope sheave 4a too much hangs on other reversion that to be configured be that life-time dilatation with rope 3 is associated.
As shown in Figure 1, be at car under the state of the superiors, the part of the lost of life of rope 3 is to be accompanied by the decline of car from driving the directional run length part of rope sheave 4a along balance block side reversion wheel 5.The part that hangs on track adjusting wheel 1a, 1b under the car from cage side reversion wheel 2 is passed through 3 rope sheaves, and 3 rope sheaves are circular groove, so rope 3 can short life.
But if bont 4 too high settings, the part that drives on the rope sheave 4a that is suspended on of rope 3 too arrives track adjusting wheel 1b even 1a under the car by cage side reversion wheel 2, damages the life-span.So, the hanging on actuating device 4a part and can not hang reversion wheel more than 2 of rope 3, so, bont 4 the position is set, for example, can above orlop is ground-surface, be arranged in the scope of following formula.
TR≤Hc+Sc+Hmc
Here, TR be lifting travel length, the Hc of elevator be car when the superiors from cage side reversion wheel 2 to car under the distance of track adjusting wheel, Sc is the rope coiling length of cage side reversion wheel 2, Hmc takes turns 2 length to bont 4 from above-mentioned cage side reversion.
Calculate the scope that is provided with of actuating device 4 with concrete numerical value.Use following numerical value as an example.Unit is a rice.
TR＝15、Hc＝2.5、Sc＝0.6
From the superiors ground to the length X t=2 of cage side reversion wheel 2.In addition, highly be made as Xd from orlop ground to being provided with of being asked of actuating device 4, so,
Hmc＝TR+Xt-Xd
∴Hmc＝TR+2-Xd
So
TR≤Hc+Sc+TR+2-Xd
∴Xd≤2.5+0.6+2＝5.1
Between promptly supposing above actuating device 4 is set from orlop ground to 5.1m, then the part of the driving rope sheave 4a that is wound on actuating device 4 of rope 3 is in the descending stroke 2 of car, only hang on the cage side reversion wheel, track adjusting wheel under its front-end configuration car not is so can improve the life-span of rope 3.

Hang over the number of times on other the reversion wheel by the part that reduces the driving rope sheave 4a by bont 4 as far as possible, thereby reach the life-span of rope 3, can bont 4 be set in following formula scope.
TR≤Ho+So+Hmo
Here, TR is that lifting travel length, the Ho of elevator is car 1 distance from balance block side reversion wheel 5 to the balance block hanging wheel 6a of balance block when orlop, So is the rope coiling length of balance block side reversion wheel 5, and Hmo is balance block side reversion wheel 5 length to bont 4.Equally use concrete numerical value to calculate the scope that is provided with of actuating device 4 with example 1.Use following numerical value as an example.Unit is a rice.
TR＝15、Ho＝1、So＝0.6、Xt＝2
Hmo(＝Hmc)＝TR+Xt-Xd
So,
TR≤Ho+So+TR+2-Xd
∴Xd≤1+0.6+2＝3.6
Between promptly supposing above actuating device 4 is set from orlop ground to 3.6m, then the part of the driving rope sheave 4a that is wound on actuating device 4 of rope 3 is in upward stroke, only hang on the balance block side reversion wheel, can not dispose the balance block hanging wheel car of the balance block that hangs over its front end, so can improve the life-span of rope 3.
