The 3rd, be configured in the balance weight of horizontal surface one side in the access trunk 1, the 18th, winch, be configured in and leave the top opposite position of car 2 sides of gangway 15, promptly with the resignation face 17 corresponding positions of car 2, and be installed in the below position of access trunk 1, be provided with the driving rope sheave 6 of pivot dress by vertical axis.This driving rope sheave 6 is positioned at the top ceiling side of the access trunk 1 of winch 18, and is relative with the top ceiling of access trunk 1.The diameter of the driving rope sheave 6 of this example is less than the profile of winch 8.According to this configuration, can effectively utilize top ceiling and the formed space of sidewall by access trunk 1.
In addition, winch 18 relative horizontal directions inclinations (see from the side and be configured to oblique shape).That is, winch 18 is inclined in vertical projection its part and overlaps each other with car 2, other parts between car 2 and access trunk 1 wall, with the overlapping part of car 2 than other parts top ceiling of close access trunk 1 also.In addition, winch 18 is arranged to be positioned at the side wall side of access trunk 1 as far as possible.
7 are provided in a side of car first pulley on one side of car 2 bottoms, and 8 are provided in a side of car second pulley on the car 2 bottom opposite sides.
9 are provided in a side of the balance weight pulley on balance weight 3 tops, the 10th, the cage side deflection sheave, in vertical projection, be configured in the inwall and the space between the car 2 of access trunk 1, be journaled into the top of access trunk 1 and be configured in and car second pulley 8 opposite position places by horizontal axis.
The 11st, balance weight side deflection sheave is configured in vertical projection in the inwall and the space between the car 2 of access trunk 1, is journaled into the top of access trunk 1 and is configured in and balance weight pulley 9 opposite position places by horizontal axis.Cage side deflection sheave 10 and balance weight side deflection sheave 11, and configuration cage side deflection sheave 10 is configured in the inwall and the space between the car 2 of access trunk 1 in the same manner.This configuration helps reducing the cross-sectional area of access trunk 1.
In this example, in the space between the sidewall of car 2 and access trunk 1, dispose winch 18 and deflection sheave 10,11 on the top in the space that disposes balance weight 3 especially, effectively utilized balance weight 3 needed spaces are set.In addition, winch 18 can be understood from Fig. 3, is configured in the corner near access trunk 1, with the interference of minimizing and car 2 as far as possible.
In addition, cage side deflection sheave 10 and the side of the relative intersecting each otherly car 2 of plane of revolution of balance weight side deflection sheave 11, the wall tilted configuration of access trunk 1.
19 be provided in a side of on the bottom surface of access trunk 1, respectively with the energy disperser of car 2 and balance weight 3 corresponding configurations.
The 12nd, main push-towing rope, one end utilization and car first pulley 7 is corresponding and be configured in the first rope retainer 13 on access trunk 1 top and be connected with the top of access trunk 1 and descend, around hanging on car first pulley 7 and car second pulley 8 and rising, hang up to horizontal direction around hanging on the cage side pulley 10 then, take turns on 11 around hanging over to drive on the rope sheave 6 and around hanging over the balance weight sideslip, it is descended rise around hanging on the balance weight pulley 9 back, other end utilization and balance weight pulley 9 are corresponding and be configured in the second rope retainer 14 on access trunk 1 top and be connected with the top of access trunk 1.
This main push-towing rope 12, the part criss-cross in horizontal projection from cage side deflection sheave 10 to the partial sum that drives rope sheave 6 from driving rope sheave 6 to balance weight side deflection sheave 11.But, winch 18 tilted configuration, main push-towing rope 12 is vertically producing skew around hanging over the position that drives on the rope sheave 6 because of the reel beginning and the end of reeling, so the part from driving rope sheave 6 to balance weight side deflection sheave 11 can not interfere with each other from cage side deflection sheave 10 to the partial sum that drives rope sheave 6.Thus, become big, increased towability around hanging over the winding angle θ that drives the main push-towing rope 12 on the rope sheave 6.
Though cage side deflection sheave 10 is arranged on the position that is lower than balance weight side deflection sheave 11, this is because main push-towing rope 12 finishes vertically producing the out-of-position cause because of reel beginning and coiling around hanging over the position that drives on the rope sheave 6.
In the lift appliance that as above constitutes, winch 18 stressed, driving rope sheave 6 generation rotations make car 2 and balance weight 3 lifting round about mutually by main push-towing rope 12.In addition, winch 18 is configured in the top in the access trunk 1 and has save the Machine Room of independent setting, thereby can save the space that the lift appliance of building is used.
In addition, winch 18 lower end that is installed in the upper end of access trunk 1 and is configured in winch 18 is than top position also, the lower end of deflection sheave 10,11.In addition, winch 18 is located at and leaves the top opposite position of car 2 sides of gangway 15, promptly with the resignation face 17 corresponding positions of car 2.In addition, cage side deflection sheave 10 and balance weight side deflection sheave 11 are configured in the gap of inwall of the edge portion of car 2 and access trunk 1.
And, at the upside of winch 18 driving rope sheave 6 is set, and main push-towing rope 12 is hanged up on driving rope sheave 6 to horizontal direction.Therefore, can quite with building installation winch 18 on the formed access trunk 1 of height of the floor height of floor (not shown) topmost, and can hang up main push-towing rope 12.
Owing to can make the below of access trunk 1 approach car 2,, can save lift appliance the required expenditure on construction in space is set so need not to be provided with the below of access trunk 1 to such an extent that be higher than the building floor height of floor topmost.In addition, because of playing the height of this effect and reduction building, so can eliminate the unfavorable condition of invading close to buildings power at sunshine.
In addition, because the part from driving rope sheave 6 to balance weight side deflection sheave 11 can not interfere with each other from cage side deflection sheave 10 to the partial sum that drives rope sheave 6 in the main push-towing rope 12, and it is cross-shaped in horizontal projection, so can increase the winding angle θ that drives the main push-towing rope 12 on the rope sheave 6 around hanging over, thereby can increase towability.
The increase of this towability brings following such effect.
In the lift appliance, if with car weight be made as W1, staffing weight is made as W2, counterweight is made as W3, then designs counterweight W3 with W1+W2 * 1/2=W3.The towability that drives rope sheave 6 need be adjusted according to the increase and decrease of the numerical value of W3/W1, but with the cost-cutting is purpose in recent years, the continuous lightweight of cage (W1 minimizings), and in this case, it is big that W3/W1 becomes, and just needs the increase towability.Therefore,, just can more make the cage lightweight by increasing towability, but cost-cutting.
In addition, towability e
K θ(k: by the constant of the groove shape decision that drives rope sheave, θ: represent winding angle), obtain in desire under the situation of same towability that if winding angle θ can be made as N doubly, then cell constant k is that 1/N is doubly just passable.
Be made as H if will drive the hardness of rope sheave 6, the wearing depth that then drives rope sheave is directly proportional with m/H.Here, m is by the constant of the groove shape decision that drives rope sheave, increases and decreases along with the increase and decrease of groove coefficient k.Obtain in desire under the situation of same towability, if obtain winding angle θ more greatly, then the groove coefficient k is less just passable, and m also diminishes.Therefore, drive the increase that the lower material of rope sheave hardness H also can suppress wearing depth, can guarantee to drive the life-span of rope sheave even use.For this reason, can select the lower inexpensive material of hardness.
In addition, shown in this example, intersect, and can eliminate the tension force of main push-towing rope 12 by making main push-towing rope 12.Figure 20 represents main push-towing rope, and coiling on the rope sheave 6 begins and the axial force of the reel situation that ends up being criss-cross and uncrossed situation driving.As shown in figure 20, if the tension force of main push-towing rope 12 is made as P, then axial force needs 2P under uncrossed situation, and by making its intersection, then axial force becomes 2P1 less than 2P, can reduce the load that acts on the axle that drives rope sheave 6.Thus, can design the axle that drives rope sheave 6 thinner, or must be lower with its Intensity Design.
Example 2

Example 6
This example be special version in access trunk 1 with the fixing structure of the erecting bed of usefulness of winch, deflection sheave 10,11 and deflector wheel 23.
Figure 18 is the lateral plan that is provided with the state of winch, deflection sheave 10,11 and deflector wheel 23 erecting beds of being fixed, and Figure 19 is cross-sectional birds-eye view (vertical projection diagram).
The 25th, erecting bed, this erecting bed be, sets up beam on 2 guide rails that 2 guide rails and the balance weight of car 2 usefulness are used, and is fixed into one with this beam.On this erecting bed 25, with the relative horizontal direction tilted configuration of winch, and the S.

Example 7
Figure 21, Figure 22 represent this example, and Figure 21 is a lateral plan, and Figure 22 is the cross-sectional birds-eye view (vertical projection diagram) of main portion.
In this example, at the below position of access trunk 1 relative horizontal direction tilted configuration winch, this point is identical with previous example, difference is that the vertical projection from cage side deflection sheave 10 to the partial sum that drives rope sheave 6 from driving rope sheave 6 to the part of balance weight side deflection sheave 11 does not intersect.
Among the figure, the symbolic representation same section identical with aforesaid Figure 15～Figure 17 omits explanation.Winch 18 in this example also is provided with the driving rope sheave 6 of diameter less than the profile of winch 18 in the top ceiling side.Therefore, can effectively utilize by the top ceiling of access trunk 1 and the formed corner space of inwall of access trunk 1.
In this example, in the main push-towing rope 12, do not intersect like that as shown in figure 22 to the part of balance weight side deflection sheave 11 in addition from cage side deflection sheave 10 to the partial sum that drives rope sheave 6 from driving rope sheave 6.But green phase is obliquely installed winch 18 to horizontal direction, then compares with existing example can reduce and the rope angle of deviation of 23 on deflection sheave 11, deflector wheel.
The top ceiling position of car 2 that in addition, can be when rising to topmost from car 2 required size A when the size B of the top ceiling of access trunk 1 is provided with less than horizontal arrangement winch 18.
Example 8
The following describes another example at the below position of access trunk 1 relative horizontal direction tilted configuration winch.
Figure 23, Figure 24 represent this example, and Figure 23 is a front view, and Figure 24 is the cross-sectional birds-eye view (vertical projection diagram) of main portion.
Among the figure, the symbolic representation same section identical with aforesaid Figure 15～Figure 17 omits explanation.
In addition, in this example, the deflector wheel is not set.Therefore, main push-towing rope 12 is not come driving rope sheave 6 by the deflector wheel from cage side deflection sheave 10, comes balance weight side deflection sheave 11 from driving rope sheave 6 again.
Balance weight side deflection sheave 11 is located on the gap of the car 2 that disposes balance weight 24 1 sides and fall way wall, is positioned at following (the leaving the direction of access trunk top ceiling) of cage side deflection sheave 10.In addition, the plane of revolution of cage side deflection sheave 10 and balance weight side deflection sheave 11 is set as approximate vertical.
As this example, horizontal direction is configured in winch the below position of access trunk 1 obliquely relatively, is being effective measures aspect the life-span of the groove of guaranteeing to drive rope sheave 6, main push-towing rope 12.This point is described in detail as follows.
Figure 25 is the figure that drives the position relation of rope sheave 6 and balance weight side deflection sheave 11 in the expression existing lift appliance shown in Figure 34.Among Figure 25, the rope groove that drives rope sheave 6 is a level, and the rope groove of balance weight side deflection sheave 11 is configured to vertically, and 2 rope groove spaced windings are hung main push-towing rope 12.Figure 25 (b) is the figure that sees Figure 25 (a) from the direction of arrow.In Figure 25 (b), the occasion that expression main push-towing rope 12 is made of 3 ropes.Rope 12a is set in to work as from the rope groove that drives rope sheave 6 and shifts to the rope groove hour offset of balance weight side deflection sheave 11 apart from being the position of a1.
Among Figure 25, θ 1 expression Fu Leite angle.Under the situation of Figure 25, Fu Leite angle θ 1 can following such calculating:
θ1＝Arctan(a1/L)。
This Fu Leite angle θ 1 is the numerical value how many rope grooves of the rope groove of the driving rope sheave 6 of expression by main push-towing rope 12 and balance weight side deflection sheave 11 is offset.When this numerical value was big, main push-towing rope 12 just was pressed on the rope groove side powerfully, and main push-towing rope 12 becomes big with the abrasive forces of rope groove.That is, as shown in figure 26,, then on rope groove side, acting on the power of T * sin θ, its result, the friction force of generation μ T * sin θ when the friction coefficient that tension force under the situation of Fu Leite angle θ 1, main push-towing rope 12 is made as T, rope groove and main push-towing rope 12 is made as μ.
And, exist the problem that makes the lost of life of main push-towing rope 12 and rope groove because of this friction force.Generally, guaranteeing that need be set as Fu Leite angle θ 1 below 1.5 ° on the basis in life-span in the occasion of elevator.
On the other hand, under the situation of relative horizontal direction as this example, become the position relation of Figure 27 with α angle tilt winch 18.Figure 27 (b) is the diagrammatic sketch after the round portion reservation of Figure 27 (a) is amplified.Under the situation of Figure 27, rope 12a is set in to work as from the rope groove that drives rope sheave 6 and shifts to the rope groove hour offset of balance weight side deflection sheave 11 apart from being the position of a2.Owing to winch 18 is tilted, so become the relation of a2＜a1 apart from a2.
And Fu Leite angle θ 2 becomes θ 2=Arctan (a2/L).
Because the pass of Fu Leite angle θ 1, θ 2 is Fu Leite angle θ 2＜Fu Leite angle θ 1, so can prolong a side the main push-towing rope 12 of inclination winch 18 and the life-span of rope groove.
The relation of the tilt angle alpha of winch 18 and the reduction of a2 as shown in figure 28.Can understand from this diagram of curves, in the less numerical value of angle [alpha], the distance of a2 sharply diminishes, and along with angle [alpha] becomes mild near 90 °.We know from this diagram of curves, even slightly winch 18 is tilted, also can make Fu Leite angle θ 2 become less, can obtain bigger effect.
As described above such, green phase can obtain the actv. effect to horizontal direction inclination winch 18 aspect the life-span of the rope groove of guaranteeing to drive rope sheave 6, main push-towing rope 12.
But, in design, how many degree are tilt angle alpha set depend on other key elements, for example with the relation in the space of access trunk.For example, more angle [alpha] is tilted, will set the access trunk top high more.Its result causes the increase of building cost.Therefore, in life-span of the rope groove of considering to guarantee to drive rope sheave 6, main push-towing rope 12 and do not cause in the scope that building cost increases the tilt angle alpha of necessary setting winch design in.
In addition, the rope groove of the driving rope sheave 6 that prolongation as above illustrates, the effect in the life-span of main push-towing rope 12 also can obtain in the previous example of relative horizontal direction tilted configuration winch.
In addition, the winch 18 in this example also is provided with the driving rope sheave 6 of diameter less than winch 18 profiles in the top ceiling side.Therefore, can effectively utilize by the top ceiling of access trunk 1 and the formed corner space of inwall of access trunk 1.
Example 9
Figure 29, Figure 30 represent this example, and Figure 29 is a front view, and Figure 30 is the cross-sectional birds-eye view (vertical projection diagram) of main portion.
Among the figure, the symbolic representation same section identical with aforesaid Figure 15～Figure 17 omits explanation.
In addition, the part of winch 18 and car 2 are overlapping in vertical projection diagram, and other parts are positioned on the gap of car 2 and fall way wall.
In addition, the deflector wheel is not set in this example.Therefore, main push-towing rope 12 is not come driving rope sheave 6 by the deflector wheel from cage side deflection sheave 10, comes balance weight side deflection sheave 11 from driving rope sheave 6 again.
Balance weight side deflection sheave 11 is located on the gap of the car 2 that disposes balance weight 24 1 sides and fall way wall.And cage side deflection sheave 10 is arranged to roughly the same height with balance weight side deflection sheave 11.
The purpose of above example 8,9 all is to reduce from winch 18 to the Fu Leite angle of deflection sheave 10,11, but also can make these examples combined.That is, the relative horizontal directions of winch 18 are tilted, also can be again with the relative vertical direction tilted configuration of plane of revolution of deflection sheave 10,11.
Example 10
This example be explanation in access trunk 1 with the fixing erecting bed of usefulness of winch 18, deflection sheave 10,11.
Figure 31 is a winch 18, is the cross-sectional birds-eye view (vertical projection diagram) that the erecting bed state that deflection sheave 10,11 is fixed is set.
The 25th, be fixed on the erecting bed on the guide rail top, this erecting bed is, sets up beam on 2 guide rails that 2 guide rails and the balance weight of car 2 usefulness are used, this beam engages each other and constitutes the erecting bed of one.On this erecting bed 25, horizontal arrangement winch 18, cage side deflection sheave 10 and balance weight side deflection sheave 11 also are fixed on the shared erecting bed 25.On the erecting bed of this example,, can obtain following such effect equally as implementing shown in the form 9 plane of revolution of vertical direction tilted configuration deflection sheave 10,11 like that relatively.
Because the position of winch 18, deflection sheave 10,11 relation is decided by the assembling of erecting bed 25, so the adjustment during elevator setting becomes easy.In addition, the load that acts on winch, deflection sheave 10,11 and the deflector wheel 23 is all supported by 4 guide rails by erecting bed 25, so needn't consider the intensity of access trunk 1.
In addition, winch 18, deflection sheave 10,11 being installed on the erecting bed 25 of one also is actv. aspect following.
Figure 32 is the figure that expression is installed in winch 18, deflection sheave 10,11 power of back horizontal direction on the erecting bed 25 of one.Figure 33 is the figure that expression is installed in winch 18, deflection sheave 10,11 power of back vertical direction on the erecting bed 25 of one.
At the driving rope sheave 6 of winch 18 and cage side deflection sheave 10, drive between rope sheave 6 and the balance weight side deflection sheave 11 around hanging with main push-towing rope 12, if the tension force that will act on the main push-towing rope 12 is made as T, then shown in figure 32, driving the power that axially acts on T respectively of rope sheave 6 upper edge main push-towing ropes 12.In addition, on cage side deflection sheave 10, balance weight side deflection sheave 11, also acting on tension force T respectively.These power act on the erecting bed 25 by the support that drives rope sheave 6, the axial region of deflection sheave 10,11, become the compressive force of cancelling each other but the direction vector of tension force T is identical.
Owing in erecting bed 25, make force balance, guaranteeing the structural strength of erecting bed 25 in advance, so power can not act on the car that supports erecting bed 25 with guide rail and balance weight guide rail.
In addition, if the weight of winch 18, cage side deflection sheave 10, balance weight side deflection sheave 11 and erecting bed 25 is made as W, then as shown in figure 33, the power of vertical direction becomes 2T+W.Support this power with guide rail and balance weight with guide rail by car.This power all is the axial power of guide rail, owing to be the strongest direction on the guide rail intensity, so become the applying method of desirable power.
This effect we can say that in the erecting bed 25 that formerly example 6 is put down in writing also be identical.
In addition, under the situation of this example, be provided with at the upside (top ceiling side) of winch 18 and drive rope sheave 6, main push-towing rope 12 is positioned at the top ceiling side of erecting bed 25.And, the axle of deflection sheave 10,11 all is fixed on the face of erecting bed 25 downsides, in fixing vertical section, main push-towing rope 12 on deflection sheave 10,11 outstanding to the top ceiling of erecting bed 25 around hanging the position, the lower end of deflection sheave 10,11 is following side-prominent to erecting bed 25.In other words, make the top and bottom that drive rope sheave 6 and be arranged in erecting bed 25, with the face of the opposite side that car 2 or balance weight 24 1 sides are set, main push-towing rope 12 also is positioned at the face of an opposite side around extension on deflection sheave 10,11.Thus, in the vertical section from the upper end of deflection sheave 10,11 to erecting bed 25 is set the lower end.
This structure is actvies for the space that is provided with of the short transverse of dwindling erecting bed 25, winch 18 and deflection sheave 10,11.As shown in figure 34, be provided with under the situation that drives rope sheave 6 when downside at winch 18, the short transverse of erecting bed 25, winch 18 and deflection sheave 10,11 the distance that the space becomes S1 is set.But, under the situation of this example, drive rope sheave 6 owing on the upside (top ceiling side) of winch 18, be provided with, and in the top ceiling side of erecting bed 25 main push-towing rope 12 is set, so the short transverse of erecting bed 25, winch 18 and deflection sheave 10,11 be provided with the space can be arranged to less than S1 apart from S2.In this example, two sides' of deflection sheave 10,11 S. A. is fixed on the face of erecting bed 25 downsides, main push-towing rope 12 side-prominent to the top ceiling of erecting bed 25 around hanging the position, but the such configuration of either party S. A. all can obtain same effect.
In addition, the end, two ends of main push-towing rope 12 is fixed on the erecting bed 25.Thus, the fixedly carriage of usefulness of main push-towing rope need not be set in addition.As prior art, when the end, two ends with main push-towing rope is installed on building or the guide rail, because of concentrate the tension force that has acted on main push-towing rope in the mounting portion, so building or guide rail are had requirement of strength, but the end, two ends by main push-towing rope is installed, support erecting bed 25 by a plurality of guide rails again on erecting bed 25, just can disperse supporting power.
In addition, more than the structure of explanation also applicable to the erecting bed 25 of example 6.
In addition, in this example, be that erecting bed 25 is fixed on 2 cars, 2 usefulness guide rails and 2 balance weights with the top of guide rails, but, also can be installed on the inwall of access trunk 1 as long as the wall of access trunk 1 has enough intensity.In addition, both erecting bed 25 only can be fixed on the car 2 usefulness guide rails, also can only be fixed on balance weight with on the guide rail.And, also can in above-mentioned 4 guide rails, select any radical to fix.
