Definitions
- the present invention relates to an elevator apparatus in which a driving machine is disposed at an upper portion in a hoistway.
- Japanese Patent Application Laid-Open No. Hei 10-139321 shows an elevator apparatus, so called machine-room-less elevator that does not have a machine room above a hoistway, where a driving machine is disposed at an upper portion in the hoistway.
- an elevator apparatus so called machine-room-less elevator that does not have a machine room above a hoistway, where a driving machine is disposed at an upper portion in the hoistway.
- the height of a building can be shortened in comparison to a case where the machine room is separately provided above the hoistway, there is a need to keep a space for disposing the driving machine at the upper portion in the hoistway. Accordingly, it is desirable that the height dimension of the hoistway be reduced by utilizing space in the hoistway as efficiently as possible.
- an elevator apparatus comprising: a hoistway; a car raised and lowered in the hoistway; a counterweight disposed behind the car and raised and lowered in the hoistway; a driving machine for raising and lowering the car and the counterweight, having a driving machine body disposed at an upper portion in the hoistway and a driving sheave which is rotated by the driving machine body; and a main rope wound around the driving sheave and suspending the car and the counterweight in the hoistway, wherein the driving machine body is disposed to overlap a rear corner portion of the car in a vertically projected surface, the driving machine is disposed so that an axis of the driving sheave extends at an angle with respect to a width direction of the car, and
- Fig. 1 is a plan view showing an elevator apparatus according to a first embodiment of the present invention
- Fig. 2 is a cross-sectional view of an essential portion taken along the line II-II in Fig. 1
- Fig. 3 is a cross-sectional view of an essential portion taken along the line III-III in Fig. 1.
- a pair of car guide rails 2 and a pair of counterweight guide rails 3 are installed in a hoistway 1.
- a car 4 is guided by the car guide rails 2 to be raised and lowered in the hoistway 1.
- a counterweight 5 is disposed behind the car 4 and guided by the counterweight guide rails 3 to be raised and lowered in the hoistway 1.
- a mounting frame 6 is fixed in the vicinity of the top portions of the car guide rails 2 and the counterweight guide rails 3.
- the mounting frame 6 has a plurality of beams 7 and a supporting base 8 fixed onto the beams 7.
- a driving machine 9 for raising and lowering the car 4 and the counterweight 5 are mounted on the supporting base 8.
- the driving machine 9 has a driving machine body 10 including a motor, and a driving sheave 11 which is rotated by the driving machine body 10.
- the driving machine body 10 is disposed to overlap a corner portion of the rear portion of the car 4 in a vertically projected surface. Also, the driving machine 9 is disposed so that the axis of the driving sheave 11 extends at an angle with respect to a width direction of the car 4 (the right and left direction in Fig.1).
- a plurality of main ropes 12 suspending the car 4 and the counterweight 5 in the hoistway 1 are wound around the driving sheave 11.
- One end portion of the main ropes 12 are connected to the mounting frame 6 through a counterweight side rope fastener 13.
- a car side rope fastener 14 is fixed in the vicinity of the upper end portions of the car guide rails 2. The other end portions of the main ropes 12 are connected to the car side rope fastener 14.
- a pair of car suspending sheaves 15 around which the main ropes 12 are wound are provided at the bottom portion of the car 4.
- a counterweight suspending sheave 16 around which the main ropes 6 are wound is provided at the top portion of the counterweight 5.
- Rotatable first and second return pulleys 17 and 18 guiding the main ropes 12 from the driving sheave 11 to the car 4 are attached to the mounting frame 6 spaced from one another in a horizontal direction.
- the first and second return pulleys 17 and 18 are disposed to be located between a side surface of the car 4 and a wall surface 1a of the hoistway 1 when the car 4 moves to the upper portion in the hoistway 1.
- the main ropes 12 are extended downward from the driving sheave 11, wound around the first return pulley 17, extended obliquely upward, further wound around the second return pulley 18, and extended downward. That is to say, the positions of the main ropes 12 in the horizontal direction are shifted by the combination of the first and second return pulleys 17 and 18. Because of this, the main ropes 12 are guided to the car suspending sheaves 15 at a reasonable angle.
- Fig. 4 is a perspective view showing the construction of the main rope 12 in Fig. 1.
- an inner strand layer 24 having a plurality of inner strands 22 and filling strands 23 disposed in gaps between the inner strands 22 is disposed around a core rope 21.
- Each inner strand 22 is composed of a plurality of aramid fibers and an impregnating agent such as polyurethane or the like.
- the filling strands 23 are composed of, for example, polyamide.
- An outer strand layer 26 having a plurality of outer strands 25 is disposed around the outer periphery of the inner strand layer 24.
- Each outer strand 25 is composed of a plurality of aramid fibers and an impregnating agent such as polyurethane or the like just as in the inner strands 22.
- a friction reducing covering layer 27 for preventing abrasion from friction between strands 22 and 25 at the sheaves such as at the driving sheave 2a or the like is disposed between the inner strand layer 24 and the outer strand layer 26. Further, a protective covering layer 28 is disposed around the outer periphery of the outer strand layer 26.
- This synthetic fiber rope has a higher friction coefficient and superior flexibility in comparison to steel rope.
- first and second return pulleys 17 and 18 are disposed to be located between the side surface of the car 4 and the wall surface 1a of the hoistway 1 when the car 4 moves to the upper portion in the hoistway 1, the height dimension of the hoistway 1 is not increased by the first and second return pulleys 17 and 18, thereby efficiently utilizing the space in the hoistway 1.
- the main ropes 12 are composed of a synthetic fiber rope having a high friction coefficient and superior flexibility, the diameters of the driving sheave 11 and the first and second return pulleys 17 and 18 can be reduced, thereby reducing the size of installation space. Accordingly, the space in the hoistway 1 can be utilized even more efficiently, thereby reducing the height dimension of the hoistway 1.
- Fig. 5 is a plan view showing an elevator apparatus according to a second embodiment of the present invention
- Fig. 6 is a cross-sectional view of an essential portion taken along the line VI-VI in Fig. 5.
- first and second counterweight suspending sheaves 31 and 32 around which the main ropes 12 are wound are provided at the upper portion of the counterweight 5 spaced from one another in a horizontal direction.
- the width dimension of the car 4 is larger than that in the first embodiment and the weight of the car 4 is also heavier, and consequently the width dimension of the counterweight also becomes larger.
- the other constructions are the same as in the first embodiment.
- first and second counterweight suspending sheaves 31 and 32 are juxtaposed with each other, if the width dimension of the counterweight 5 is changed according to a change in the dimensions of the car 4 in the width direction, it can be easily dealt with by merely changing the distance between the first and second counterweight suspending sheaves 31 and 32.
