Detailed ways

Next, examples of the present invention will be described below.

Example 1

Embodiment 1 of the present invention will be described using FIGS. 1-3 .

Fig. 1 is a perspective view showing the structure of an elevator device without a machine room according to Embodiment 1 of the present invention, Fig. 2 is a top view showing the elevator device without a machine room according to Embodiment 1, and Fig. 3 is a hoisting machine fixing part, from the arrow A in Fig. 2 The view you see. In the drawings, the same symbols as those in the conventional example represent the same or equivalent components as those in the conventional elevator apparatus.

16 is the mechanical platform equipped with winch 4. The mechanical platform 16 is fixed on the top of the car guide rail 9 . As shown in FIG. 2, the mechanical platform 16 partially overlaps with the car 7 in plan view. The machine table 16 can also be made to be fixed on the counterweight guide rail 10 . The drive wheel 5 of the hoist 4 is disposed facing the wall side of the hoistway 1 , and the motor unit 6 is disposed facing the car 7 side of the inner hoistway 1 . Therefore, in a plan view, the drive wheel 5 is located in the gap between the hoistway wall and the car, and the motor part 6 overlaps with the car.

17 is an anti-vibration component that is located between the hoist 4 and the mechanical platform 16 and elastically supports the vertical load.

18 is the anti-vibration device that is fixed on the machine platform and suppresses the lateral vibration of the winch when it is working. This anti-vibration device 18 is made an integral body with mechanical platform 16, car guide rail 9. Under the situation that the mechanical platform 16 is also fixed on the counterweight guide rail 10 , the anti-vibration device 18 is integrated with the mechanical platform 16 , the car guide rail 9 , and the counterweight guide rail 10 .

19 is an anti-vibration part located between the hoist 4 and the anti-vibration device 18, elastically supporting the horizontal direction load generated when the hoist laterally shakes, and this anti-vibration part can be an elastic body such as rubber.

The anti-vibration device 18 is composed of an L-shaped member, and surrounds the back surface, the upper surface, and the surface of the motor unit 6 of the hoist 4 . The anti-vibration members 19 are disposed between the back side of the motor unit 6 and the anti-vibration device 18 and between the front side of the motor unit 6 and the anti-vibration device 18 . This structure is suitable for supporting the lateral swing of the hoist 4 .

One end of the cable 13 descends from the driving wheel 5, rises after passing the pulley 11 at the bottom of the car 7, and then connects to the cable fixed end 14 at the top of the car guide rail 9. The other end of the cable 13 descends from the drive wheel 5 , rises after passing through the pulley 12 of the counterweight, and then connects to the cable fixed end 15 at the top of the counterweight guide rail 10 .

In the above structure, as long as the necessary gap between the car 7 and the hoistway wall is guaranteed to be at least as thick as the driving wheel 5, the horizontal cross-sectional area of the hoistway can be reduced. Its effect is related to the situation that the drive wheel 5 of the hoist 4 faces the wall direction of the hoistway 1 and the hoist 4 is arranged on the hoistway of the car 7 .

Since the motor part 6 of the hoisting machine 4 is disposed facing the car 7 side, inspection and maintenance of the motor part 6 and the braking device installed near the motor part 6 become easy. In particular, it is advantageous for the maintenance personnel to ride on the ceiling of the car 7 for inspection and maintenance.

In addition, since the relationship between the hoist 4 and the car pulley 11 and the relationship between the hoist 4 and the car 7 are maintained on the basis of the car guide rail 9, even if the size of the car 7 changes, the center of gravity of the car 7 can always be adjusted. hanging nearby. In addition, the car 7 is not easy to tilt, so the comfort of the elevator ride can be ensured.

In addition, in this embodiment, the hoist is not disposed between the car 7 and the hoistway wall, but as shown in FIG. 2 , a part of the hoist 4 overlaps with the car 7 as it is. Even when the size of the hoist 4 needs to be increased as the size of the car increases, it is not necessary to change the size of the gap between the car 7 and the hoistway wall. In the case of the conventional example, the cross-sectional area must be increased due to the enlargement of the car 7, and the cross-sectional area must be increased due to the enlargement of the clearance between the hoistway of the car 7 and the wall of the hoistway, so the total cross-sectional area And in the case of the present embodiment, it is only necessary to increase the cross-sectional area that must be increased due to the enlargement of the car 7.

Therefore, this embodiment can be designed to have a smaller total cross-sectional area than the conventional example.
