Elevator device {ELEVATOR DEVICE}

6 and 7 show a conventional machine roomless elevator described in Japanese Patent No. 2593288.

In the meantime, 1 represents the hoistway, 2 represents the bit portion, and 3 represents the upper part of the hoistway. 4 shows a traction machine arranged on the hoistway 3 and constituted by a traction sheave 5 and a motor 8. 7 is a car for elevating in the hoistway, and 8 is a counterweight for elevating in the hoistway. 9 is two car guide rails which guide the lifting and lowering of the car 7, and 10 are two counterweight additional trails which guide the lifting and lowering of the counterweight 8. 11 is at the bottom of the car 7 and is two suspension pulleys provided near the car guide rail 9. 13 is a wire rope, one end of which is fixed to the karof stop 14 of the hoistway 3, and ascends through two suspension pulleys 11. In addition, the outer rope 13 is wound on the drive pulley 5 of the hoisting machine 4, descends, passes through the suspension slide 12, and ascends, and the other end is fixed to the counterweight lobe stop 15. The driving force of the hoist 4 is transmitted by the wire rope 13.

The hoisting machine 4 is disposed inside the car 7 and the hoistway 1 wall toward the car side with the drive pulley 5 above the car guide rail 9 and the motor part 6 toward the wall side of the hoistway 1. have. As shown in Fig. 7, the hoist 4 is arranged in a space between the wall of the hoistway and the hoistway of the car.

Next, the operation will be described with reference to FIG. 6. As the hoisting machine 4 drives, the drive pulley 5 rotates so that the wire rope 13 moves by traction. As the wire rope 13 moves, the car 7 and the counterweight 8 move up and down in the up and down directions, respectively.

As described above, the conventional machine roomless elevator has a driving pulley 5 disposed between the car 7 and the hoistway 1 wall toward the car side, and has the following problems.

(1) When the hoisting machine 4 needs to be enlarged due to the enlargement of the car 7, it is necessary to widen the receiving space of the hoisting machine 4 between the car 7 and the hoistway 1 wall. The cross sectional area of the becomes large.

(2) Since the motor part 6 is on the wall side, it is difficult to check and repair the brakes (not shown) arranged on the motor part 6 side, avoiding oil of electric parts or ropes constituting the motor.

The present invention is an elevator without a machine room and the installation position of the hoist is disposed on the hoistway.

[Configuration of Invention]

Next, an Example is demonstrated about this invention as follows.

Example 1.

Embodiment 1 of the present invention will be described with reference to Figs.

1 is a structural perspective view of an elevator apparatus without a machine room according to Embodiment 1 of the present invention, FIG. 2 is a plan view of an elevator apparatus without a machine room according to Embodiment 2, and FIG. 3 is a view seen from the firebox A of FIG. . In the drawings, the same reference numerals as in the conventional example indicate that they are the same or equivalent parts to the conventional elevator apparatus.

16 is a mechanical stand on which the hoist 4 is disposed. The platform 16 is fixed to the upper part of the car guide rail (9). As shown in FIG. 2, part of the workbench 16 overlaps the car 7 in plan view. The machine table 16 may be fixed to the counterweight additional rail 10. The hoist 4 arrange | positions the drive pulley 5 toward the wall side of the hoistway 1, and arrange | positions the motor part 6 toward the car 7 side of the hoistway 1. As shown in FIG. Therefore, in the plan view, the drive pulley 5 is located at the gap between the hoistway wall surface and the car, and the motor part 6 is positioned overlapping with the car.

17 is an anti-vibration material provided between the hoist 4 and the machine base 16 to elastically support the vertical load.

18 is a brace fixed to the bench 16 and which suppresses rolling at the start of the hoist. The brace 18 is integrated with the machine table 16 and the car guide rail (9). When the machine stage 16 is also fixed to the counterweight additional rail 10, the brace 18 is integrated with the machine stage 16, the car guide rail 9, and the counterweight 10. As shown in FIG.

19 is an anti-vibration material provided between the hoist 4 and the brace 18 to elastically support the horizontal load generated when the hoist 4 is rolled.

As the dustproof material, an elastic body such as rubber is used.

The brace 18 is formed of an L-shaped member, and surrounds the rear surface, the upper surface, and the surface of the motor portion 6 of the hoisting machine 4. The dustproof material 19 is disposed between the rear surface side and the brace 18 of the motor portion 6 and between the surface side and the brace 18 of the motor portion 6, respectively.

Such a structure is a structure suitable for supporting the rolling of the hoisting machine 4.

One of the ropes 13 descends from the drive pulley 5 and ascends through the suspension pulley 11 below the car 7 and is connected to the rope stop 14 on the upper guide rail 9. The other side of the rope 13 descends from the drive pulley 5 and ascends through the suspension pulley 12 of the counterweight, and is connected to the rope stop 15 of the upper portion of the counterweight rail.

In the structure, since the gap required between the car 7 and the hoistway wall should at least have a thickness equivalent to the drive pulley 5, the cross-sectional area of the hoistway plane can be reduced. The effect relates to arranging the drive pulley 5 of the hoisting machine 4 in the wall direction of the hoistway 1, and the hoister 4 being arranged on the hoistway of the car 7.

Since the motor part 6 of the hoisting machine 4 is arranged toward the car 7 side, maintenance inspection of the brake apparatus attached to the motor part 6 and the motor part 6 vicinity becomes easy. In particular, it is advantageous when a maintenance worker performs a maintenance check on the ceiling top surface of the car 7.

In addition, since the relationship between the hoisting machine 4 and the car suspension vehicle 11 and the hoisting machine 4 maintain the relationship between the car 7 on the basis of the car guide rail 9, the size of the car 7 is increased. Even if it changes, the center root of the car 7 can always be suspended. Moreover, since the car 7 does not incline, comfortable riding can be maintained.

In addition, in this embodiment, the hoisting machine 4 is not arrange | positioned between the car 7 and the hoistway wall, As shown in FIG. 2, a part of the hoisting machine 4 and the car 7 are arrange | positioned from the beginning. Even when the size of the hoist 4 is increased due to the increase in size of the car 7, there is no need to change the gap size between the car 7 and the hoistway wall. In the case of the conventional example, the cross sectional area is increased by increasing the cross sectional area due to the enlargement of the car 7 and widening the gap between the lifting passage of the car 7 and the lifting wall. In the present embodiment, it is possible to respond only by increasing the cross sectional area due to the enlargement of the car 7.

Therefore, this embodiment can design the whole cross sectional area smaller than the conventional example.
