As a result, the hoisting machine 6 and the hoisting machine mounting part 71 are held so as to be slidable to the guide rails 5a and 5b. The guide portions 81a, 81b, 82a, and 82b may be mounted when the frame 711 is placed at the bottom of the hoistway 1.

Next, the hoisting machine 6 and the hoister mounting part 71 are lifted up while slidingly moving to the guide rails 5a and 5b (S5 of FIG. 9). At this time, the guide portions 81a and 82a and the guide portions 81b and 82b are mounted so as to be separated from the members 721a and 721b in the projection image viewed from the upward direction, respectively. The hoisting machine mounting part 71 is lifted in the state in which the clearance gap was formed in the space | interval and the space | interval of guide part 81a, 82a and guide part 81b, 82b. After the hoist 6 and hoist 71 are lifted to a predetermined height, the bolt 816 is loosened and along the long hole 815, the guide portion 81a is formed as shown in FIG. 721a).

Next, the force applied to the hoisting machine mounting mechanism 7 will be described. As shown in FIG. 3, the force F is applied to the drive sheave 6a of the hoist 6 by the suspension means 10. Since the driving sheave 6a is arrange | positioned at the position which was out of the frame 711, the moment acts on the hoisting mounting part 71 via the hoisting machine 6 by this force F. As shown in FIG. This moment is applied to the guide rails 5a and 5b and the rail mounting portions at the mounting positions of the hoisting mount 71 and the rail mounting portion 72, that is, the positions of the guide portions 81a and 82a and the guide portions 81b and 82b. Exerts a reaction force against 72). As a result, bending moments are generated in the guide rails 5a and 5b and the rail mounting portion 72 in the lengthwise range including the guide portions 81a and 82a and the guide portions 81b and 82b, respectively.

In addition, the mounting intervals of the hoistway walls of the guide rails 5a and 5b, that is, the mounting intervals of the rail brackets 53a and the rail brackets 53c, and the mounting intervals of the rail brackets 53b and the rail brackets 53d, are included. Even in the range, a bending moment acts on the guide rails 5a and 5b, respectively. The rail mounting portion 72 is mounted to the guide rails 5a and 5b substantially over the range including the mounting intervals of the hoistway walls of the guide rails 5a and 5b, and the bending moment is also applied to the rail mounting portion 72 within this range. Works.

As described above, the hoisting machine mounting mechanism 7 according to the first embodiment includes the hoisting machine mounting part 71 for mounting the hoisting machine 6 and the rail mounting part 72 for mounting the hoisting machine mounting part 71 to the guide rails 5a and 5b. ), The rail mounting portion 72 is mounted to the hoisting mounting portion 71 within the lengthwise range of the guide rails 5a and 5b, and the hoisting mounting portion (in the longitudinal direction of the guide rails 5a and 5b). It is attached to the guide rails 5a and 5b over the installation range of 71).

Thereby, the cross-sectional performance of the hoist mounting mechanism 7 in the mounting range of the hoist mounting part 71 in the longitudinal direction of the guide rails 5a and 5b improves compared with the case where only the guide rails 5a and 5b. Therefore, the bending moment acting on the guide rails 5a and 5b equivalently can be made small.

Moreover, the rail mounting part 72 is attached to the guide rails 5a and 5b substantially over the range including the mounting space | interval of the hoistway wall of the guide rails 5a and 5b. Thereby, the cross-sectional performance of the hoisting machine mounting mechanism 7 in this range improves compared with the case where only the guide rails 5a and 5b. Therefore, the bending moment acting on the guide rails 5a and 5b equivalently can be made small.

In addition, the guide rails 5a and 5b have rail mounting surfaces 55a and 55b on the side opposite to the rail guide portions 52a and 52b on the rail bottom portions 51a and 51b, and the rail mounting portions 72 are rails. It is attached to the mounting surface 55a, 55b. As a result, the rail guide portions 52a and 52b are not impeded in mounting the rail mounting portions 72 to the guide rails 5a and 5b, so that the rail mounting portions 72 can be configured with a simple structure. At the same time, mounting can be facilitated.

Moreover, since the guide parts 81a, 82a, 81b, and 82b which are slidable to the guide rails 5a and 5b are attached to the hoisting mounting part 71, the hoisting machine 6 and the hoisting machine mounting part 71 are elevated by the lifting path 1 Since the guide rails 5a and 5b are guided when they are installed at a predetermined height, the lifting can be made stable and the installation work can be facilitated.

The guide portions 81a and 82a and the guide portions 81b and 82b are mounted to the hoisting mounting portion 71 so as to be detachable from the members 721a and 721b in the projection image viewed from the upward direction, respectively. Has) Thereby, the hoisting mounting part 71 can be lifted in the clearance gap in the space | interval of the member 721a and the member 721b, and the space | interval of the guide part 81a, 82a, and guide part 81b, 82b. Therefore, the member 721a, 721b and the guide parts 81a, 82a, 81b, 82b do not twist, and can make installation easy.

In addition, by configuring the guide portions 81a, 82a, 81b, and 82b to the rail mounting portion 72, the guide portions 81a, 82a, 81b, and 82b are shared as a fixing member to reduce the number of parts. Can be. In addition, the guide parts 81a, 82a, 81b, and 82b can be mounted at any position with respect to the rail mounting part 72, and the mounting height of the hoisting machine 6 can be selected freely.

For example, in a building where the top of the hoistway 1 is high, the tops of the guide rails 5a and 5b are supported by the building beams at the top of the hoistway 1, and thus the guide rails 5a and 5b. The top of the) also needs to be high. At this time, when the mounting position of the hoist 6 is uniform from the upper ends of the guide rails 5a, 5b, the hoist 6 is also installed at a high position of the hoistway 1, so that the installation worker or the maintenance worker need more than Will work at a higher position. In this embodiment, since the mounting height of the hoisting machine 6 can be selected freely, it is not necessary to install the hoisting machine 6 higher than necessary, and installation work, maintenance work, etc. become easy.

Since the guide parts 81a, 81b, 82a, and 82b are attached to the rail mounting part 72, and the hoisting machine 6 is attached to the hoisting mounting part 71 via the elastic bodies 715a, 715b, 716a, 716b, The dust-proof effect of suppressing propagation of the vibration generated in 6) to the guide rails 5a and 5b can be obtained. In addition, there is no need to provide an elastic body between the guide portions 81a, 82a, 81b, 82b and the guide rails 5a, 5b to prevent dust, and to mount the elastic bodies 715a, 715b, 716a, 716b), dustproof effect can be obtained with a small number of configurations.

Moreover, since the shaking of the arrow J direction of FIG. 3 by the vibration of the hoisting machine 6 is supported by the elastic bodies 715a, 715b, 716a, 716b arrange | positioned up and down of the hoisting machine 6, a dustproof effect can be improved further. . In addition, although two elastic bodies were respectively provided in the upper and lower sides of the hoisting machine 6, it is not limited to this, It is good also as a structure which provided one elastic body in the upper center and one lower center of the hoisting machine, and three each in the upper and lower sides You may provide the above elastic bodies.

Moreover, since the hoist mounting mechanism 7 has the rail connection part 73 which connects the guide rails 5a and 5b with each other in the upper side of the guide rails 5a and 5b, it is the space | interval of the guide rails 5a and 5b. Unevenness can be prevented and a highly reliable elevator apparatus can be obtained. In addition, although the rail connection part 73 was attached to the member 721a, 721b, you may mount directly on the guide rail 5a, 5b.

As a result, even if the rail mounting portion 72 and the guide rails 5a and 5b are loosened, the force F applied to the hoisting machine 6 is supported by the contact portions 722a and 722b. A highly reliable elevator device can be obtained.

Further, even when the abutting portions 722a and 722b are mounted without being in contact with the upper ends of the guide rails 5a and 5b, the rail mounting portion 72 and the guide rails 5a and 5b are fastened. This slide and the rail mounting portion 72 may move downward, but the contact portion 722a, 722b is caught on the upper ends of the guide rails (5a, 5b) to support the force F applied to the hoisting machine (6). Highly reliable elevator apparatus can be obtained.

For example, in the case of a bolted fastening which forms a mounting hole in the guide rails 5a and 5b and allows a bolt to pass through the mounting hole to be fastened to the rail mounting portion 72, even if the fastening slides, the bolt is mounted. The force F applied to the hoisting machine 6 is supported by engaging with. In this case, not only the mounting holes are machined in the guide rails 5a and 5b, but the cross-sectional performance of the cross sections of the guide rails 5a and 5b in these mounting holes is lowered, so that the strength of the guide rails 5a and 5b is reduced. Degrades. However, according to this embodiment, since the force F applied to the hoisting machine 6 is supported by the abutting portions 722a and 722b, it is not necessary to process the mounting holes in the guide rails 5a and 5b, and the strength does not decrease. Nor do.

In addition, since the suspension means mounting portion 12 for mounting the suspension means 10 is provided in the hoisting mounting portion 71, a member for attaching the suspension means is unnecessary, and the number of parts can be reduced.

Moreover, when the girders are provided on the guide rails 5a and 5b and the hoisting machine 6 is installed on the girders, the height direction of the hoistway 1 is required. However, in this embodiment, the hoisting machine 6 and the hoisting machine mounting part are provided. Since 71 is provided in the range of the longitudinal direction of the guide rails 5a and 5b, the hoisting machine 6 can be provided without increasing the height direction of the hoistway 1.

In addition, in this embodiment, although the hoisting mounting part 71 is arrange | positioned in the longitudinal direction range of the guide rails 5a and 5b when it sees from a horizontal direction, the part of the hoisting mounting part 71 is the length of the guide rails 5a and 5b. You may arrange | position so that it may come out from the range of a direction.
