In this embodiment, the car-side turning pulley 10 and the counterweight-side turning pulley 11 are arranged in parallel with each other. And the main rope 12 in the part from the car-side turning pulley 10 to the driving sheave 5 and the main rope 12 in the part from the driving sheave 5 to the counterweight-side turning pulley 11 are parallel to each other. Such an arrangement is advantageous because the winding angle of the main rope 12 around the drive sheave 5 can be increased.
In this embodiment, the counterweight-side turning pulley 11 is arranged between the car 2 and the hoistway wall in the plan view, and the rotating surface of the counterweight-side diverting pulley 11 is also parallel to the hoistway wall. It is.

Next, a method for fixing the mounting base 15 will be described with reference to FIGS.
The mount 15 includes a first beam 151, a second beam 152, a third beam 153 connecting the two beams 151, 152, a fourth beam 154, and a fifth beam. It is.
The first and second beams 151 and 152 are fixed to the car guide rail 14 via the suspension member 20. That is, as shown in FIG. 8, the upper bent portion of the suspension member 20 is hung on the upper end of the car guide rail 14 to fix the car guide rail 14 and the suspension member 20, and the lower side of the suspension member 20. The first beam 151 or the second beam 152 is hung on the bent portion and fixed. In this way, the beams 151 and 152 are suspended and held from the upper end of the car guide rail 14.
Further, as shown in FIG. 7, one end of the third beam is fixed to the first beam 151 via the anti-vibration rubber 22, and the other end is fixed to the second beam 152 via the anti-vibration rubber 22. The
As shown in FIG. 8, one end of the fourth beam 154 is fixed to the fifth beam 155 that connects the first beam 151 and the second beam 152 via the anti-vibration rubber 22, and the other end is the second beam. It is fixed to the beam 152 via the anti-vibration rubber 22. In this way, the fourth beam 154 is also integrated with the second beam 152 via the anti-vibration rubber 22.

The first beam 15 1 is fixed speed governor 16, the third beam 153 car-side turning pulley 10 is fixed, weight-side deflection pulley 11 balancing the fourth beam 154 is fixed.
The hoisting machine 4 is fixed to both the third beam 153 and the fourth beam 154. The first rope stopper 121 is fixed to the second beam 152, and the second rope stopper 122 is fixed to the fifth beam 155.
In the case of the above-described configuration, the third beam 153, the hoisting machine 4 attached to the fourth beam 154, the car-side turning pulley 10, and the counterweight-side turning pulley 11 are supported in an anti-vibration manner. The third beam 153 and the fourth beam 154 correspond to members to which the hoisting machine 4, the car-side turning pulley 10, and the counterweight-side turning pulley 11 are attached. This member is fixed to the first beam 151 and the second beam 152 via a vibration isolating member. Therefore, the load generated on the hoisting machine, the car-side turning pulley 10, and the counterweight-side turning pulley 11 can be supported by the guide rail, and vibration generated by these devices can be reduced from being transmitted to the guide rail. Can do. Therefore, it is effective in that the vibration and noise to the living room adjacent to the elevator can be blocked and a high quality elevator apparatus can be obtained. Further, since it is possible to reduce the vibrations generated in the hoisting machine 4, the car-side turning pulley 10, and the counterweight-side turning pulley 11 being transmitted to the car guide rail 14, the riding comfort of the car is also improved.

In the case of the fixing method described above, if the car guide rail 14 is erected in the hoistway 1, the first and second beams 151 and 152 are connected to the third and third beams via the suspension member 20. 5 parts 153 to 155, and the hoisting machine 4, the car-side turning pulley 10 and the counterweight-side turning pulley 11 are sequentially assembled with parts that can be suppressed to a weight of 30 kg or less except for the hoisting machine 4. Therefore, a large construction such as preparing a crane on the roof in advance or passing a hole provided in the ceiling of the hoistway becomes unnecessary.

The third beam 153 and the fourth beam 154 have the following functions in addition to simply installing the above-described devices.
7-9, the 3rd beam 153 and the 4th beam 154 have covered the both sides | surfaces and upper surface of the cage side turning pulley 10 or the counterweight side turning pulley 11, and comprised the turning pulley cover.

When the hoisting machine 4 is installed, the hoisting machine 4 can be lifted up to the top of the hoistway 1 by the lifting pulley 25. Therefore, when installing the hoisting machine 4, a large-scale construction such as preparing a crane on the roof in advance or passing a hole provided in the ceiling of the hoistway becomes unnecessary.
Incidentally, a temporary placing beam 26 of the hoisting machine 4 is also provided at the fifteenth attachment. When installing the hoisting machine 4, the hoisting machine 4 is first lifted by a winch for normal installation from the lower part of the hoistway to the temporary placing beam 26, and the hoisting machine 4 is temporarily placed on the temporary placing beam 26. After that, it is lifted to an appropriate installation position using the lifting pulley 25.

The attachment structure of the car-side turning pulley 10 with respect to the third beam 153 is as follows.
The car-side turning pulley 10 is provided with a hollow shaft 28, and a solid shaft 29 is passed through the hollow shaft 28 to fix the third beam 153 and the car-side turning pulley 10. With this configuration, the third beam 153 can be easily attached even if the third beam 153 has a deep drawing shape so that the attachment portion of the car-side turning pulley 10 becomes a part of the soundproof cover. Accordingly, productivity and on-site installation are improved. The mounting structure of the counterweight-side turning pulley 11 with respect to the fourth beam 154 is the same.

Although the mounting base 15 is described as being fixed to the car guide rail 14 in this embodiment, it may be fixed to the counterweight guide rail 13 as well. Moreover, it is also possible to comprise so that it may fix only to the counterweight guide rail 13. FIG.
