Description

Elevator system without machine room {MACHINE ROOM-LESS ELEVATOR SYSTEM}

The present invention relates to an elevator system (machine room-less elevator system) that does not have a separate machine room, and more particularly, to minimize the influence of the torsion moment due to noise, vibration, and the lift car load applied to the hoist sieve. A machine room free elevator system having a hoist support assembly supporting a hoist.

1 shows a hoist of an elevator system without a machine room according to the prior art. The hoist 6 is mounted by holding members 2a, 4a, 4b of approximately "c" shape and is fixed to counterweight guide rails 5a, 5b by fixing members 7a, 7b, 7c, 7d. The anti-vibration rubbers 3a and 3b are disposed between the fixing members 7c and 7d and the horizontal plate 2b at the lower portion thereof so as to reduce vibrations when the hoisting machine is operated. Moreover, in order to support the load of the fixing members 7a, 7b, 7c, 7d and the hoisting machine 6, the pair of supporters 1a, 1b are being fixed to the guide rails 5a, 5b.

The illustrated prior art hoist support structure has the disadvantage, however, that by applying the hoist to the guide rail, the load applied to the hoist is transferred directly to the guide rail, thereby deforming the guide rail.

Figure 2 introduces another hoist support structure of an elevator system without a machine room according to the prior art.

In the prior art shown, the hoist 16 is fixed to the beam 12 with the anti-vibration rubber 14 therebetween and the upper and left and right sides thereof are surrounded by the frame member 20. Both ends of the beam 12 are fixed in a state accommodated in the receiving groove 10 formed in the wall (8) of the building. The frame member 20 is fixed to the beam 12 to hold and hold the anti-vibration rubber 14 on the top of the hoist 16.

In the illustrated prior art hoist support structure, the shaft center of the hoist or hoist sheave is located higher than the height of the beam. Thus, the beam receives a large torsional moment when the load of the elevator car is put on the sheave of the hoist. This torsion moment provides a cause for the shaft of the hoisting sheave to oscillate in the vertical direction when the elevator car moves, thereby lowering the riding comfort and increasing the noise. In addition, it causes the stability of the elevator system.
