The specific embodiment
Following with reference to description of drawings form of implementation of the present invention.
Fig. 1 is the partial schematic diagram of hoist cable 5 method for winding of the lift facility of expression the present invention first form of implementation.Fig. 2 is the top plan view of hoist trunk 6 of the elevator of this form of implementation.The lift facility of this form of implementation is constituted as, and lift car 1 is along lift car guide rail 16a, 16b lifting, and counterbalanced weight 2 is along counterbalanced weight guide rail 17a, 17b lifting.And lift car 1 and counterbalanced weight 2 are suspended in midair by three one group hoist cable 5, and are driven by the rope sheave 4 that is arranged on the winch 3 in the hoist trunk.
Be arranged in the moving area and the space between the hoist trunk wall 11 of lift car 1 on the position in the close elevator hole of winch 3 below hoist trunk 6 middle bodies.First deflection sheave 7 and second deflection sheave 8 are arranged on the below of this winch 3, the axle of first deflection sheave 7 is positioned on the roughly the same position of the height on right side with respect to the axle of the axle 8 of second deflection sheave, the left end of first deflection sheave 7 is positioned at right-hand member than rope sheave 4 and keeps left on the position of side, and the right-hand member of second deflection sheave 8 is positioned on the left end position on the right side than rope sheave 4.
At this, " right side " or " left side " among the present invention be meant respectively, from right side or the left side of winch 3 when the position observation winch 3 that axially (any one side at the front or the back side) separates.That is to say that the method for arranging of the machinery and equipment of the elevator in the hoist trunk of the present invention 6 also comprises the symmetrical method for arranging of layout with Fig. 1 etc. certainly.Therefore, in Fig. 1, comprise that the driver train of winch 3 and first deflection sheave 7 and second deflection sheave 8 also can be arranged near any wall in two the parallel walls among the figure.And, in this form of implementation, shown in the top plan view of Fig. 2, be that example describes near the situation of the wall setting of Fig. 1 top with driver train.
The method for winding of the hoist cable 5 in this form of implementation as shown in Figure 1.At first, side from the hoist cable 5 that rope sheave 4 extends towards the below obliquely in the mode of being partial to it, extend from turning to towards the top after the right side part of rope sheave 4 extends to the left part that reaches first deflection sheave 7, behind two the 3rd deflection sheavies 9 that are arranged on hoist trunk 6 tops, and arrive the hoist cable fixed part 12 on hoist trunks 6 tops via two the underslung type pulleys 14 that are arranged on lift car 1 bottom.And, the opposing party in the above-mentioned hoist cable 5 extends from the left part of rope sheave 4 to turn to towards the top after the right side part that arrives second deflection sheave 8 and extends, behind two the 4th deflection sheavies 10 that are arranged on hoist trunk 6 tops, and via the hoist cable fixed part 13 of the counterbalanced weight suspention that is arranged on counterbalanced weight 2 tops with arrival hoist trunk 6 tops, pulley 15 back.In addition, as shown in Figure 2, the vertical projection of the 3rd deflection sheave 9 is configured to the vertical projection approximate vertical with the vertical projection and the rope sheave 4 of the 4th deflection sheave 10.
In addition, first deflection sheave 7 and second deflection sheave 8 are arranged side by side on one-piece type pedestal 18, and the height of the axle of two pulleys is basic identical.At this, first deflection sheave 7 and second deflection sheave 8 are configured to and can regulate the position of these two pulleys by on the fixed part of the bearing of two pulleys a plurality of not shown bolts hole being set along the vertical direction.
And the winch 3 in this form of implementation is slim winch.At this, slim winch is meant that the radial dimension of winch framework profile is greater than the winch of axial width size.
According to this form of implementation, because first deflection sheave 7 and the 8 adjacent settings of second deflection sheave, so can be at the size b that on the direction of hoist trunk wall 11, dwindles the driver train single-piece horizontal direction that constitutes by winch 3 and first deflection sheave 7 and second deflection sheave 8.And, the winding angle of hoist cable 5 on rope sheave 4 can be set for greater than 180 °, because the raising of the friction force between rope sheave 4 and the hoist cable 5, so can improve driving efficiency.In addition, because in this form of implementation, the deadweight of hoist cable 5 acts on the rope sheave 4, thus with first deflection sheave 7 be not set below winch 3 compare with the structure of second deflection sheave 8, it is big to have the friction force that acts on the rope sheave 4, the advantage that driving efficiency is high.
And, in this form of implementation,, first deflection sheave 7 and second deflection sheave 8 be arranged on the highly essentially identical position because arranging, so can dwindle driver train single-piece size h up and down, that can reduce winch 3 cheats 21 height of starting at from elevator.In addition, owing to can on identical height and position, carry out the maintenance operation of winch 3 and first deflection sheave 7 and second deflection sheave 8, so also have the effect that can shorten working hours.
In addition, because driver train is arranged on the position in close elevator hole of hoist trunk 6 belows, so the pedestal 18 that can adopt bolt 20 that support driving mechanism is used is fixed on the floor 21 that elevator cheats, so can simplify the mounting structure of driver train.And, owing to carry out the installation exercise and the maintenance operation of driver train on the floor 21 in lift stand hole, so, even in the elevator that the Machine Room is not set, also can carry out the installation exercise and the maintenance operation of driver train easily.
As mentioned above, owing to can dwindle the lateral dimension b of driver train and size h up and down simultaneously, so help realizing the miniaturization of whole hoist trunk.And according to present embodiment, the occasion that is arranged on hoist trunk 6 tops with winch 3 is identical, because downward load acts on the rope sheave 4 from hoist cable 5, so, if according to design, when the top of hoist trunk 6 has been provided with winch 3, then can directly use this winch 3.And, owing to be arranged on the moving area of lift car 1 and the described winch 3 in the space between the hoist trunk wall 11 is slim winchs, so as shown in Figure 2, can design the wall of the elevator lobby opposition side of hoist trunk 6 and the interval between the lift car 1 narrower, therefore from the result, can further realize the miniaturization of hoist trunk 6.And, also can constitute driver train by being arranged in the moving area and the space between the hoist trunk wall 11 of lift car 1 on the position that the non-slim close elevator of winch 3 below the hoist trunk middle body cheated.
Followingly second form of implementation of the present invention is described with reference to Fig. 3 and Fig. 4 and Fig. 5.The integral structure of lift facility and first form of implementation are basic identical.Be that with the difference of first form of implementation as Fig. 3 and shown in Figure 5, with the below of the rope sheave 4 that is arranged on winch 3, a bottom deflection sheave 19 under being actually has replaced first deflection sheave 7 and second deflection sheave 8.In addition, same hoist cable (for example hoist cable 5a) be at the lower portion coiling secondary of bottom deflection sheave 19, so, as shown in Figure 4,, on bottom deflection sheave 19, be adjacent to be provided with two grooves with respect to a hoist cable.Owing to be that three hoist cables (5a, 5b and 5c) are provided with these grooves respectively, so offered 6 grooves on the bottom deflection sheave 19 altogether in regular turn.
The following method for winding that the hoist cable 5 of this form of implementation is described with reference to Fig. 3.At first, the left part that the side the hoist cable 5 that extends from rope sheave 4 towards the below extends arrival bottom deflection sheave 19 from the left part of rope sheave 4 turns to via groove afterwards and extends towards the top.Then, this hoist cable 5 is via two lift cars usefulness deflection sheavies 22 that are arranged on hoist trunk 6 tops, and two underslung type pulleys, the 14 back hoist cable fixed parts 12 that arrive hoist trunk 6 tops by being arranged on lift car 1 bottom.And the opposing party the hoist cable 5 that extends from rope sheave 4 towards the below extends to the right side part that reaches bottom deflection sheave 19 from the right side part of rope sheave 4, turns to the back to extend towards the top by other the groove beyond the described groove.Then, this hoist cable 5 with deflection sheave 23, and arrives the hoist cable fixed part 13 on hoist trunk 6 tops via two counterbalanceds weight that are arranged on hoist trunk 6 tops with pulley 15 backs by the counterbalanced weight suspention that is arranged on counterbalanced weight 2 tops.In addition, because the slightly larger in diameter of bottom deflection sheave 19 is in the diameter of rope sheave 4, so can prevent the hoist cables 5 of 19 extensions from each rope sheave 4 towards the bottom deflection sheave and produce interference from bottom deflection sheave 19 towards the 3rd deflection sheave 9 or between the hoist cable 5 of the 4th deflection sheave 10 extensions.
And, according to this form of implementation, owing to below winch 3, be provided with 1 bottom deflection sheave 19, thus with compare in transversely arranged above-mentioned first form of implementation that two deflection sheavies are set, can further dwindle the width dimensions of driver train single-piece lateral dimension b or base 18.
