And a sorase car, which is connected in a slanting manner via ropes, and a machine beam that supports the vertical load that acts from the machine bed that includes the drive device and the sheave, and a sorase beam that supports the load that acts on the sorase car. TECHNICAL FIELD The present invention relates to an elevator apparatus including the above, and more particularly, to an elevator apparatus in which a machine beam is downsized and a hoist installation position can be lowered.

[0002]

2. Description of the Related Art Conventionally, an elevator apparatus has a lifting cage and a counterweight connected to each other in a slipping manner via ropes by a sheave and a sorrel wheel which are rotated by a drive apparatus provided directly above the drive apparatus. It is composed of a machine beam that supports a vertical load acting from a machine bed equipped with a device and a sheave, and a sorase beam that supports a load exerted by a sorase wheel.

FIG. 7 is a front view showing a structural example of a conventional elevator apparatus of this type. In FIG. 7, a sheave 2 rotated by the drive device 1 and a sorrel wheel 3 are arranged in the upper part of the hoistway, and the hoisting car 5 is attached to one end of the rope 4 wound around the sheer wheel 2 and the sorrel wheel 3, Balancing weights 6 are respectively arranged at the remaining ends, the sheave 2 is rotated by the drive device 1, and the driving force is transmitted to the rope 4 by frictional engagement between the rope 4 and the sheave 2. And the counterweight 6 is moved up and down.

The vertical load acting from the machine bed 7 is supported by the machine beam 8. Furthermore, the load applied by the sorase wheel 3 is the sorase beam 9
Supported by

By the way, in such an elevator apparatus, the sorase beam 9 is fixed to the machine bed 7 by bolts as shown in a plan view of FIG. 8 and a side view of FIG. , Shaft 10
It has a function of supporting through.

Since the length of the sorase beam 9 is shorter than the span of the building beam (hereinafter referred to as building spacer) 15, the vertical load acting on the machine bed 7 is
It cannot be supported by the sorase beam 9, but is supported only by the machine beam 8.

Therefore, the size of the elevator apparatus is increased, and
As the vertical load acting from the machine bed 7 increases, the vertical load supported by the machine beam 8 increases, and the machine beam 8 is enlarged in order to satisfy the strength standard.

As a result, since the installation position of the hoisting machine 11 becomes high, there is no room for the height limitation of the machine room, which is disadvantageous in terms of installability and maintainability, and the center of gravity of the hoisting machine 11 is high. As a result, the seismic resistance may be reduced.

This is because the conventional method of supporting the hoisting machine 11 is
This is a problem caused by the structure in which the vertical load acting on the machine bed 7 is supported only by the machine beam 8.

On the other hand, the conventional 2: 1 roping elevator apparatus requires the hitch plate 12 and the hitch beam 13 for fixing the ends of the rope 4 as shown in the side view of FIG. The problem becomes even more prominent.

[0011]

As described above, in the conventional elevator apparatus, the hoisting machine installation position becomes higher as the vertical load acting from the machine bed increases. As a result, there is no room for the height limitation of the machine room, which is disadvantageous in terms of installation and maintainability, and the center of gravity of the hoisting machine is high.

Therefore, in the elevator apparatus according to the first aspect of the present invention, the function of supporting a part of the load in the vertical direction applied from the machine bed is added to the sorase beam to support each machine beam. Since the load applied can be reduced, the machine beam can be downsized and the hoist installation position can be lowered.

As a result, there is a margin for the height limitation of the machine room, which is advantageous in terms of installation and maintenance, and the center of gravity of the hoisting machine is lowered,
Seismic resistance can be improved.

Further, in the invention corresponding to claim 2, the lifting car and the counterweight are connected in a rope manner by ropes by a sheave and a sorrel wheel rotated by a drive device provided directly above. In an elevator apparatus composed of a machine beam supporting a vertical load acting from a machine bed including the drive device and the sheave, and a sorase beam supporting a load acting by a sorase wheel,
The longitudinal length of the Solase beam is extended to a length substantially equal to the longitudinal length of the machine beam so as to support a part of the vertical load exerted by the machine bed.

Therefore, in the elevator apparatus according to the second aspect of the invention, the length of the sorase beam in the longitudinal direction of the machine beam is set so as to support a part of the vertical load acting from the machine bed. Since it is possible to reduce the supporting load per machine beam by extending the machine beam to a length substantially equal to the length of the machine beam, the machine beam can be downsized and the hoisting machine installation position can be lowered. .

As a result, there is a margin for the height limitation of the machine room, which is advantageous in terms of installation and maintenance, and the center of gravity of the hoisting machine is lowered,
Seismic resistance can be improved.

Further, in the invention corresponding to claim 3, in the elevator apparatus of the invention corresponding to claim 1 or 2, the sorase beam is placed on the building beam through a vibration isolator made of an elastic member such as rubber. I'm trying to place it.

Therefore, in the elevator apparatus according to the third aspect of the invention, the seismic resistance can be further improved by disposing the sorase beam on the building beam via the vibration isolator made of an elastic member. .

Furthermore, in the invention corresponding to claim 4, in the elevator apparatus of the invention corresponding to claim 1 or claim 2, the sorase beam supports the hitch plate for fixing the rope end portion. It is arranged.

Therefore, in the elevator apparatus according to the fourth aspect of the present invention, by arranging the sorase beam so as to support the hitch plate for fixing the rope end portion, the rope end portion can be fixed during the 2: 1 roping. A hitch plate for fixing can be installed without adding a hitch beam.
