Abstract
Description
- The present invention relates to a traction elevator apparatus in which a counterweight is disposed behind a car, and particularly relates to a load supporting construction that is effective for machine-roomless types.
- In elevators that are conventional machine-roomless two-to-one (2:1) roping method traction elevators, and that have a construction in which a counterweight is disposed behind a car, and a hoisting machine is installed in an upper portion of a hoistway, a first car guide rail is installed on a first hoistway side wall, and a second car guide rail is installed on a second hoistway side wall that faces the first hoistway side wall. When the hoistway is viewed from directly above, the counterweight is disposed so as to be close to the second hoistway side wall, and the hoisting machine is disposed obliquely in an upper portion of a hoistway corner portion in which the counterweight is disposed.
- The hoisting machine is installed on a machine base that is disposed horizontally in an upper portion inside the hoistway. The machine base is supported by first and second counterweight guide rails and the second car guide rail. The first counterweight guide rail is installed on the hoistway rear wall at an intermediate portion in the width direction of the hoistway. The second counterweight guide rail is installed on the second hoistway side wall.
- The car and the counterweight are suspended by a main rope. A first end portion of the main rope is connected to a car rope fastening beam that is fixed to an upper portion inside the hoistway. A second end portion of the main rope is connected to a counterweight rope fastening beam that is fixed to an upper portion inside the hoistway. The car rope fastening beam is fixed to a building in a vicinity of the first hoistway side wall. The counterweight rope fastening beam is mounted onto an upper end of the first counterweight guide rail.
- First and second car suspending sheaves are disposed on a lower portion of the car. The first and second car suspending sheaves are disposed such that the main rope crosses the lower portion of the car obliquely when the hoistway is viewed from directly above. A counterweight suspending sheave is disposed on an upper portion of the counterweight.
- The main rope is wound sequentially from the first end portion around the first car suspending sheave, the second car suspending sheave, the sheave of the hoisting machine, and the counterweight suspending sheave to the second end portion. Specifically, the main rope, which extends almost directly downward from the car rope fastening beam, is deflected horizontally at the first car suspending sheave, crosses the lower portion of the car obliquely, and is deflected almost directly upward at the second car suspending sheave. The main rope, which extends almost directly upward from the second car suspending sheave, is deflected almost directly downward at the sheave of the hoisting machine, is deflected almost directly upward again at the counterweight suspending sheave, and reaches the counterweight rope fastening beam (see
Patent Literature 1, for example). -
- When a machine-roomless elevator in which a compact hoisting machine is installed in a top portion inside a hoistway is configured, the hoisting machine must inevitably be placed on an uppermost portion of the counterweight guide rails since it is preferable that it be installed in a vicinity of a boundary line between the car and the counterweight when viewed from directly above. In order to keep elevator riding comfort satisfactory and to minimize the load acting on the car guide rails from the car guiding shoes to avoid increases in the size of the car guide rails, it is also necessary for the main rope that crosses the lower portion of the car to pass through the center of gravity of the car when viewed from directly above.
- For this reason, in conventional elevators such as that described above, the counterweight is placed on one side of the hoistway, the hoisting machine is installed above that counterweight, and the first and second car suspending sheaves are disposed such that the main rope crosses the lower portion of the car obliquely. As a result, the portion of the main rope between the first end portion and the first car suspending sheave is disposed as close as possible to a landing, and is disposed at a position that is separated significantly from the first car guide rail.
- Thus, because the first end portion of the main rope is separated from the first car guide rail, it is difficult to mount the car rope fastening beam to the first car guide rail from a design perspective, and the car rope fastening beam is fixed to the building. However, some problems have been that fixing the car rope fastening beam to the building increases the cost burden on the building, and that time spent on design for installing the elevator in the building is increased.
- In addition, because the counterweight is placed close to one side of the hoistway, another problem has been that if a post of the building protrudes into the hoistway corner portion, it is necessary to enlarge the hoistway by an amount proportionate to those protruding dimensions. If the hoistway cannot be increased, on the other hand, another problem has been that only an elevator that has reduced carrying capacity can be installed.
- The present invention aims to solve the above problems and an object of the present invention is to provide an elevator apparatus that can reduce time spent on design for installing the elevator apparatus in a building without mounting a car rope fastening member to the building, and that does not require enlargement of a hoistway even if a building post protrudes into a hoistway corner portion.
- In order to achieve the above object, according to one aspect of the present invention, there is provided an elevator apparatus including: a car that is raised and lowered inside a hoistway; a pair of car guide rails that are installed on two sides of the car inside the hoistway, and that guide raising and lowering of the car; a counterweight that is disposed behind the car, and that is raised and lowered inside the hoistway; a pair of counterweight guide rails that are installed on two sides of the counterweight inside the hoistway, and that guide raising and lowering of the counterweight; a hoisting machine that is installed in an upper portion inside the hoistway, that has a driving sheave, and that raises and lowers the car and the counterweight; first and second suspending means that are wound around the driving sheave, and that suspend the car and the counterweight; a first car suspending sheave that is disposed on a lower portion of the car, and around which the first suspending means is wound; a second car suspending sheave that is disposed on a lower portion of the car, and around which the second suspending means is wound; a counterweight suspending sheave that is disposed on the counterweight, and around which the first and second suspending means are wound; a first car rope fastening member that is disposed in an upper portion inside the hoistway, and to which a first end portion of the first suspending means is connected; a second car rope fastening member that is disposed in an upper portion inside the hoistway, and to which a first end portion of the second suspending means is connected; and a counterweight rope fastening member that is disposed in an upper portion inside the hoistway, and to which second end portions of the first and second suspending means are connected, the first and second suspending means cross the car obliquely from a vicinity of front end portions of left and right side surfaces of the car to a central portion of a back surface when viewed from directly above, a machine base that supports the hoisting machine and the counterweight rope fastening member is fixed to the counterweight guide rails in an upper portion inside the hoistway, first and second side beams are disposed in an upper portion inside the hoistway, the first and second side beams are disposed on two sides of the car when viewed from directly above, and are fixed to the machine base or the counterweight guide rails and the car guide rails, and tension from the first and second suspending means that acts on the first and second car rope fastening members is supported by the first and second side beams.
- In an elevator apparatus according to the present invention, because the tension of the first and second suspending means that acts on the first and second car rope fastening members is borne so as to be distributed between the first and second side beams, and the first and second side beams are fixed to the machine base and the car guide rails, the first and second car rope fastening members are not mounted to the building, enabling time spent on design for installing the elevator apparatus in a building to be reduced. The counterweight can also be disposed centrally in the width direction of the hoistway, making it unnecessary to enlarge the hoistway even if a building post protrudes into a corner portion of the hoistway.

The first and second side beams 15 and 16 are disposed parallel to the depth direction of the car 6 (the depth direction of the hoistway 1). The
machine base 8 and the side beams 15 and 16 are disposed at positions that do not overlap with thecar 6 when viewed from directly above. The side beams 15 and 16 are disposed on the left and right sides of thecar 6 when viewed from directly above. - A first car rope fastening member (a first car hitch) 17 is fixed to a front end portion (an end portion on the landing side) of the
first side beam 15. A second car rope fastening member (a second car hitch) 18 is fixed to a front end portion of thesecond side beam 16. The first and second carrope fastening members car 6 when viewed from directly above. - A counterweight rope fastening member (a counterweight hitch) 19 is fixed to the
machine base 8. The counterweightrope fastening member 19 is disposed directly above thecounterweight 7. The counterweightrope fastening member 19 is disposed closer to the secondcounterweight guide rail 5 than the center line in the width direction of thecounterweight 7 when viewed from directly above. - The
car 6 and thecounterweight 7 are suspended inside thehoistway 1 by first and second suspendingmeans 20 and 21 (omitted fromFigures 1 and2 ). The first suspendingmeans 20 is constituted by a plurality of ropes or a belt. The second suspendingmeans 21 is also constituted by a plurality of ropes or a belt. The number and configuration of the second suspendingmeans 21 are similar or identical to the number and configuration of the first suspendingmeans 20. - Intermediate portions of the first and second suspending

A first end portion of the second suspendingmeans 21 is connected to the second carrope fastening member 18. A second end portion of the second suspendingmeans 21 is connected to the counterweightrope fastening member 19. - On a lower portion of the
car 6 are disposed: a plurality of (in this case, a pair of) firstcar suspending sheaves means 20 is wound; and a plurality of (in this case, a pair of) secondcar suspending sheaves means 21 is wound. Rotating shafts of the firstcar suspending sheaves car suspending sheaves - The first
car suspending sheaves car 6 such that the first suspendingmeans 20 crosses thecar 6 obliquely from a vicinity of a front end portion (a vicinity of a first corner portion on a front-surface side of the car 6) of a first side surface of the car 6 (a side surface that faces the first car guide rail 2) to a central portion of a back surface when viewed from directly above. - The second
car suspending sheaves car 6 such that the second suspending means 21 crosses thecar 6 obliquely from a vicinity of a front end portion (a vicinity of a second corner portion on a front-surface side of the car 6) of a second side surface of the car 6 (a side surface that faces the second car guide rail 3) to a central portion of a back surface when viewed from directly above. - The second
car suspending sheaves car suspending sheaves car suspending sheaves car suspending sheaves car 6 when viewed from directly above. - A plurality of (in this case, a pair of)
counterweight suspending sheaves means counterweight 7. Thecounterweight suspending sheaves counterweight 7. Thecounterweight suspending sheaves counterweight 7 when viewed from directly above. - Rotating shafts of the
counterweight suspending sheaves counterweight suspending sheaves Figure 3 ). - The first suspending
means 20 extends directly downward from the first carrope fastening member 17, is deflected horizontally by the firstcar suspending sheave 22, crosses the lower portion of thecar 6 obliquely, is deflected upward by the firstcar suspending sheave 23, is deflected downward by the drivingsheave 14, is deflected horizontally by thecounterweight suspending sheave 26, is deflected upward by thecounterweight suspending sheave 27, and is connected to the counterweightrope fastening member 19. - The second suspending
means 21 extends directly downward from the second carrope fastening member 18, is deflected horizontally by the secondcar suspending sheave 24, crosses the lower portion of thecar 6 obliquely, is deflected upward by the secondcar suspending sheave 25, is deflected downward by the drivingsheave 14, is deflected horizontally by thecounterweight suspending sheave 26, is deflected upward by thecounterweight suspending sheave 27, and is connected to the counterweightrope fastening member 19. - The
car 6 and thecounterweight 7 are thereby suspended using a two-to-one (2:1) roping method, and are raised and lowered in opposite directions to each other by the rotation of the drivingsheave 14. - A joining
member 28 is fixed between the front end portions of the side beams 15 and 16. The joiningmember 28 has: ahorizontal portion 28a; and a pair offoot portions 28b that are disposed at two ends of thehorizontal portion 28a, and that have lower end portions that are fixed to the front end portions of the side beams 15 and 16. Thehorizontal portion 28a is disposed horizontally so as to be parallel to the width direction of thecar 6. Thefoot portions 28b are disposed vertically. Thehorizontal portion 28a is fixed to side surfaces on the landing side of upper end portions of thefoot portions 28b. - The joining
member 28 is disposed within a region that is constituted by a gap between the hoistway wall on the landing side and alanding door apparatus 29, the landingdoor apparatus 29, a gap between the landingdoor apparatus 29 and acar door apparatus 30, and thecar door apparatus 30 in the depth direction of thehoistway 1 when viewed from directly above. As shown inFigure 2 , thehorizontal portion 28a is disposed above the landingdoor apparatus 29 of the uppermost floor. In addition, the joiningmember 28 is disposed so as not to overlap with thecar 6 and thecar door apparatus 30 when viewed from directly above. The carrope fastening members member 28. - Now, double-dotted chain lines in
Figure 2 indicate a maximum reachable height that thecar 6 can reach on going past an uppermost floor when thecounterweight 7 has collided with a buffer (not shown) on a floor portion of thehoistway 1. InFigure 2 , for example, thecar door apparatus 30 is positioned highest among the equipment above thecar 6, and reaches a height such that a minimum gap sufficient to prevent collision with the ceiling of thehoistway 1 is left between thecar door apparatus 30 and the ceiling when thecar 6 is at the position of the double-dotted chain lines. In regard to that, because the joiningmember 28 is disposed in a position that does not overlap with thecar 6 and thecar door apparatus 30 when viewed from directly above, it will not collide with thecar door apparatus 30. - In an elevator apparatus of this kind, because the tension of the first and second suspending
means rope fastening members machine base 8 and thecar guide rails rope fastening members - The side beams 15 and 16 have cross sections that enable them to withstand bending due to the tension of the suspending
means rope fastening members means rope fastening members Figure 3 . The side beams 15 and 16 are constituted by beams that are formed by bending shaped steel or steel plate in consideration of productivity, but it is difficult to align the centers of torsion of the side beams 15 and 16 and the centers of load on the carrope fastening members - Consequently, in the case of a configuration that does not have the joining
member 28, the cross sections of the side beams 15 and 16 become extremely large in order to accommodate excessive shearing stresses due to torsion, making mounting difficult, and also increasing costs. In answer to that, since the joiningmember 28 is used inEmbodiment 1, torsional torque that acts on the side beams 15 and 16 is canceled out. Because of this, the cross-sectional shapes of the side beams 15 and 16 need only be large enough to withstand bending, enabling increases in cost to be suppressed, and also preventing constraints on mounting from arising. - During installation work, raising parts to within a short distance from the ceiling of the
hoistway 1 and fixing them is not easy, and in some cases there may also be problems such as special tools being required. In contrast to that, there are no parts that are installed at positions close to the ceiling inEmbodiment 1, as shown inFigures 1 and2 , and almost all of the parts are installed approximately level with a mounting height of the landingdoor apparatus 29 on the uppermost floor. The part that is mounted at the highest mounted position is the joiningmember 28, but the joiningmember 28 is mounted immediately above the landingdoor apparatus 29 of the uppermost floor. Consequently, installation work can be facilitated. - In addition, since the
counterweight 7 is disposed centrally in the width direction of thehoistway 1, it is not necessary to enlarge the hoistway even if a foundation of a building post protrudes into a corner portion of a pit of thehoistway 1. - Next,
Figure 4 is a front elevation that shows an elevator apparatus according toEmbodiment 2 of the present invention,Figure 5 is a side elevation that shows the elevator apparatus fromFigure 4 , andFigure 6 is a plan that shows the elevator apparatus fromFigure 4 . InFigures 4 through 6 , points that differ fromEmbodiment 1 are that the joiningmember 28 is disposed at a position that overlaps with thecar 6 when viewed from directly above, and that thehorizontal portion 28a is disposed at a position that leaves a sufficient gap that thecar 6 does not collide with the ceiling when thecar 6 is at the position of the double-dotted chain lines. The rest of the configuration is similar or identical to that ofEmbodiment 1. - In
Embodiment 1, since thefoot portions 28b are disposed on two width direction sides of thecar door apparatus 30, width dimensions of a car door are subject to constraints such that car door panels do not come into contact with thefoot portions 28b when the car door is fully open. In contrast to that, inEmbodiment 2, since the joiningmember 28 is disposed at a position at which thecar door apparatus 30 is avoided, the width dimensions of the car doors are not subject to constraints, enabling car doors that have larger dimensions also to be selected. - Next,
Figure 7 is a front elevation that shows an elevator apparatus according toEmbodiment 3 of the present invention,Figure 8 is a side elevation that shows the elevator apparatus fromFigure 7 , andFigure 9 is a plan that shows the elevator apparatus fromFigure 7 . InEmbodiment 3, mounted angles ofcar suspending sheaves 22 through 25 are modified relative toEmbodiment 1 so as to enable acar 6 to be suspended at a center of gravity. - A pair of
tubular duct members 31 that have rectangular cross sections are disposed in left and right corner portions of a front end portion of thecar 6. Theduct members 31 form penetrating spaces that pass through thecar 6 vertically. Suspending means 20 and 21 are passed through the penetrating spaces. - First and second
car suspending sheaves car 6, i.e., directly below theduct members 31. Carrope fastening members horizontal portion 28a directly above the corner portions on the front end portion of thecar 6, i.e., directly above theduct members 31. In other words, the carrope fastening members car 6 on opposite sides of a doorway of thecar 6 when viewed from directly above. - A joining
member 28 is mounted onto side beams 15 and 16 so as to pass through directly above theduct members 31. Thehorizontal portion 28a is disposed at a position that leaves a sufficient gap that the car 6 (including the car door apparatus 30) does not collide with the ceiling when thecar 6 is at the position of the double-dotted chain lines. The rest of the configuration is similar or identical to that ofEmbodiment 1. - Using this kind of construction, riding comfort during raising and lowering of the
car 6 can be improved compared to that ofEmbodiment 1, since thecar 6 can be suspended at a position that is even closer to its center of gravity. - Bending moments that act on the joining
member 28 are also reduced, since the carrope fastening members horizontal portion 28a, enabling the cross section of thehorizontal portion 28a to be reduced. Because of this, even though thehorizontal portion 28a is disposed in a space above thecar door apparatus 30, the height dimension of thehorizontal portion 28a is reduced, enabling enlargement of the height dimensions of thehoistway 1 to be suppressed. - Next,
Figure 10 is a front elevation that shows an elevator apparatus according toEmbodiment 4 of the present invention,Figure 11 is a side elevation that shows the elevator apparatus fromFigure 10 , andFigure 12 is a plan that shows the elevator apparatus fromFigure 10 . InEmbodiment 4, suspendingmeans car door apparatus 30 and alanding door apparatus 29 without usingduct members 31. The rest of the configuration is similar or identical to that ofEmbodiment 3, and similar or identical effects to those ofEmbodiment 3 can also be achieved using this kind of construction. - Moreover, in
Embodiments 1 through 4, twocounterweight suspending sheaves
InEmbodiments 1 through 4, the side beams 15 and 16 were fixed to themachine base 8, but end portions of the side beams 15 and 16 near thecounterweight 7 may also be made into a shape that is bent toward thecounterweight 7, for example, and end portions thereof fixed to thecounterweight guide rails
