Technical field

The present invention relates to a machine room-less elevator device having a hoist installed below a hoistway. Background art

In recent years, resin-coated ropes with high flexibility, such as highly flexible synthetic fiber caps, and small-diameter, high-strength steel ropes have been developed and commercialized. Miniaturization is becoming possible.

The conventional machine room reslevator system mainly used a 2: 1 roving method to realize a smaller hoist. And, by applying the above-mentioned rope, which was newly developed to the conventional machine room reslevator system that adopted the 2: 1 roving method, the sheave can be further reduced in size and the torque of the hoist can be reduced. Can be reduced. However, when the car was driven at the same speed, the smaller the sheave, the larger the number of rotations and the higher the noise.

On the other hand, in the conventional machine room-less elevator system employing the 1: 1 roving system, the rotation speed of the branch sheave becomes smaller, as compared with the elevator system employing the 2: 1 roving system, resulting in lower noise. Can be reduced, and the structure becomes extremely simple. When the 1: 1 roving method is adopted, a hoisting machine and a deflector are arranged at the upper part of the hoistway, for example, as described in WO 02/16627 A1. The rope wrapped around the hoist was then deflected and hung on a car, and the upper beam of the car was suspended at the center of gravity of the car. Therefore, there was a problem that space for installing the hoisting machine and deflector car was required above the hoistway, and the height of the building increased accordingly. Disclosure of the invention According to the present invention, a sheave is arranged in a gap between a hoistway wall and a cage at a lower part of a hoistway, and a 1: 1 roving method is realized while keeping the hoistway dimensions to a minimum, thereby reducing the space above the hoistway. However, it is possible to obtain an elevator device having a simple structure without deteriorating the noise of the hoist.

An elevator apparatus according to the present invention comprises a hoist arranged in a hoistway, a sheave positioned in a gap between a wall surface of the hoistway and one side in the width direction of the car, and a lower part of the hoistway. A first and a second cleats provided respectively on the lower sides of the car in the width direction; one side in the width direction of the car and the wall surface of the hoistway A counterweight disposed so as to be able to ascend and descend in one of a gap between the car and a depth side of the car in the depth direction and a wall of the hoistway, and a plurality of ports wound around the sheave. A hoisting rope consisting of: Raised from above It is hung on a first car turn-over wheel disposed above the sheave at the upper part of the descending road, then lowered and connected to the first rope stop, and the remaining rope of the hoisting rope is The hoistway is lifted from the sheave and is hung on a second car-side turnover provided above the sheave above the hoistway, and further placed above the second sheave stop above the hoistway. It is hung on the third car-side turnover, which is then lowered and connected to the second rope stop. BRIEF DESCRIPTION OF THE FIGURES
