The specific embodiment
Below, with reference to accompanying drawing form of implementation of the present invention is described.
Fig. 1 is the figure of hoist cable 5 method for winding of the lift facility in local expression the present invention first form of implementation, and Fig. 2 is the top plan view of the hoist trunk 6 in the lift facility of this form of implementation.The lift facility of this form of implementation is constituted as, and lift car 1 is along car guide rail 16a, 16b lifting, and counterbalanced weight 2 is along counterbalanced weight guide rail 17a, 17b lifting.And lift car 1 is suspended in midair by hoist cable 5 with counterbalanced weight 2, and is driven by the rope sheave 4 of winch 3.
On the position of the below that winch 3 is arranged on hoist trunk 6 central authorities near the elevator hole, it is in the space in the moving area of lift car 1 and the gap between the hoist trunk wall 11.First deflection sheave 7 and second deflection sheave 8 are set below this winch 3, the axle of first deflection sheave 7 is positioned at the right side of the axle of second deflection sheave 8, and be in different height and positions with the axle of second deflection sheave, the left end of first deflection sheave 7 is positioned at the left side of rope sheave 4 right-hand members, and the right-hand member of second deflection sheave 8 is positioned at the right side of rope sheave 4 left ends.And the left end of first deflection sheave 7 is positioned at the left side of second deflection sheave, 8 right-hand members.At this, right side of the present invention is meant as shown in Figure 1, during from the top view of winch 3, is the position that benchmark is positioned at the right side with rope sheave 4.
And, the hoist cable 5 that stretches out towards the below from the right-hand member of rope sheave 4 extends through first deflection sheave, 7 backs and extends towards the top, via fixing and be arranged on two the 3rd deflection sheavies 9 at hoist trunk 6 tops and extend through two of being arranged on lift car 1 bottom and go up slidings wheel 14, and arrive the hoist cable fixed part 12 at hoist trunk 6 tops.On the other hand, the hoist cable 5 that stretches out towards the below from the left end of rope sheave 4 extends through second deflection sheave, 8 backs and extends towards the top, via fixing and be arranged on two the 4th deflection sheavies 10 at hoist trunk 6 tops after, extend through the suspension pulley 15 that is installed in counterbalanced weight 2 tops, arrive afterwards on the hoist cable fixed part 13 at hoist trunk 6 tops.And as shown in Figure 2, the vertical projection of the 3rd deflection sheave 9 is configured to vertical substantially with the vertical projection of the vertical projection of the 4th deflection sheave 10 and rope sheave 4.
And first deflection sheave 7 is arranged on the different position of height with second deflection sheave 8 on the pedestal 18 of one, and the axle of two pulleys is different on upper-lower position.Described first deflection sheave 7 and described second deflection sheave 8 are configured to, and the bolt hole of the axle of two pulleys and the fixed part of bearing has a plurality of on above-below direction, thus, can regulate (not shown) to the position of two pulleys.
And described winch 3 is a kind of slim winchs.At this, so-called slim winch is meant to have the winch of the radial dimension of outling of truss greater than these characteristics of axial width size.
According to this form of implementation, because first deflection sheave 7 is arranged on the different position of height with second deflection sheave 8, so, be arranged side by side in the situation of equal height with second deflection sheave 8 with first deflection sheave 7 and compare, can make the S. A. of the S. A. of first deflection sheave 7 and second deflection sheave 8 approaching mutually in the horizontal direction at an easy rate.Specifically, when the equal diameters of the diameter of rope sheave 4 and first deflection sheave 7 and second deflection sheave 8, if these deflection sheavies are arranged side by side on identical height, then the horizontal throw d between the axle of each deflection sheave will be greater than the diameter D of rope sheave 4, but also can be as this form of implementation, horizontal throw d is arranged to diameter D less than rope sheave 4.Therefore, can dwindle the side-to-side dimensions of the whole driver train of forming by winch 3 and two deflection sheavies thereunder.
And, even first deflection sheave 7 and second deflection sheave 8 are approaching in the horizontal direction, but because the axle base of these pulleys itself can keep bigger value, so can guarantee the comfort feature and the safety of maintenance activity.Its result can set the winding angle of the hoist cable on the rope sheave 45 greater than 180 degree easily, and then improves the friction force between rope sheave 4 and the hoist cable 5, so can increase driving efficiency.Therefore, have and under certain loading condiction, to constitute the effect of more small-sized driver train.And,, have the effect that can constitute more small-sized hoist trunk as its result.
And,,,, have and can improve the effect that acts on the friction force on the rope sheave 4 so compare with the structure that deflection sheave is not arranged on winch 3 belows because the deadweight of hoist cable 5 acts on the rope sheave 4 according to this form of implementation.
And then according to this form of implementation, the situation that is arranged on hoist trunk 6 tops with winch 3 is identical, owing to downward load is arranged from 4 effects of 5 pairs of rope sheaves of hoist cable, so,, then have the effect that can directly use this winch 3 if there is the winch 3 that is designed to be arranged on hoist trunk 6 tops.
And then, according to this form of implementation, because the slim winch of described winch 3 employings in the moving area that is arranged on lift car 1 and the space in the gap between the hoist trunk wall 11, thus also have whole hoist trunk can be provided with the effect of miniaturization more.
Followingly second form of implementation of the present invention is described with reference to Fig. 3.The integral structure of lift facility and first form of implementation are roughly the same.Be that with the difference of first form of implementation second deflection sheave 8 is that pulley 8a and 8b constitute by a plurality of pulleys, pulley 8a and 8b are contiguous side by side to be provided with, and the height of the axle of these pulleys is roughly the same.
According to this form of implementation, identical with described form of implementation, have when improving driving efficiency, dwindle the effect of the lateral dimension on the direction of hoist trunk wall 11 of driver train.Especially, because first deflection sheave 7 is different with the high and low position of second deflection sheave 8, and two second deflection sheave 8a, 8b are arranged side by side in the horizontal direction, the winding angle of hoist cable 5 on rope sheave 4 can be maintained bigger angle so have, and this new effect of rising starting point position that simultaneously can free adjustment hoist cable 5.
At last, with reference to Fig. 4 the 3rd form of implementation of the present invention is described.The integral structure of lift facility and second form of implementation are roughly the same.Be that with the difference of second form of implementation among the second deflection sheave 8a, the 8b, the axle of another deflection sheave of axial ratio 8a of the deflection sheave 8b of close hoist trunk wall 11 is high, thereby is arranged side by side on the different position of height.
According to this form of implementation, identical with described each form of implementation, having can be when improving driving efficiency, dwindles the effect of the lateral dimension on the direction of hoist trunk wall 11 of driver train.
Especially, two second deflection sheave 8a, 8b are set on the different position of height, so, compare with second form of implementation, have and can shorten this new effect of hoist cable 5 total lengths.
