First, guide rails 5a and 5b are set up in hoistway 1 via rail bracket 53 and clip 54. (SI in Fig. 9). Next, the members 721a and 721b of the rail attachment portion 72 are attached to the upper arm of the guide lanes 5a and 5b via the clip 54 (S2 in FIG. 9). Note that the guide rails 5a and 5b may be erected in a state where the saddle members 721a and 721b are attached to the guide rails 5a and 5b. Next, as shown in Fig. 10, with the hoisting machine 6 attached to the bottom of the hoistway 1 with the frame body 711 [14 'body 14 715a, 715b, 716a, 716b attached] S3). At this time, the lifting machine 6 and the frame 711 are placed between the guide rails 5a and 5b. The lifting machine 6 and the frame body 711 may be separately placed between the guide rails 5a and 5b, and then the lifting machine 6 may be attached to the frame body 711.

Next, the guide rods 81a, 82a, 81b, and 82b are attached to the frame body 711 (S4 in FIG. 9). At this time, as shown in FIG. 11, the guide portion 8 la is engaged with the guide rail 5a. The guide portion 8 la is attached to the member 721a so as to be separated from the member 721a on the projection viewed from above by using the elongated hole 815 and the bolt 816 of the attachment means 814. The guide portion 81b is also attached to the frame body 711 in the same manner as the guide portion 81a. The guide portions 82a and 82b are not shown, but are attached to the frame 711 in the same manner as the guide portion 81a. As a result, the lifting machine 6 and the lifting machine mounting portion 71 are slidably held by the guide rails 5a and 5b. The guide portions 81a, 81b, 82a, 82b may be attached when the frame body 711 is placed on the bottom of the hoistway 1.

Next, the hoisting machine 6 and the hoisting machine mounting part 71 are lifted while sliding on the guide rails 5a and 5b (S5 in FIG. 9). At this time, the guide portions 81a and 82a and the guide portions 81b and 82b are attached so as to be separated from the members 72 la and 721b, respectively, on the projection viewed from above, so that the members 72 la and 72 lb The lifting machine mounting part 71 is lifted with a gap between the gap and the guide part 8 la, 82a and the guide part 8 lb, 82b. After hoisting machine 6 and hoisting machine mounting part 71 are lifted to the prescribed height, loosen bolt 816 and follow guide hole 8 la to member 72 la as shown in Fig. 7 along long hole 815. Shift like so. Then, the guide part 81a is attached to the member 721a, and the bolt 816 is tightened and attached to the lifting machine attachment part 71. The other guide portions 82a, 81b, and 82b are attached in the same manner as the force guide portion 81a that is not described. As a result, the lifting machine 6 and the lifting machine mounting part 71 are attached to the rail mounting part 72 (S6 in FIG. 9).

Next, as shown in FIG. 2, the rail connecting portion 73 is attached to the members 721a and 721b (S7 in FIG. 9). ) o The Lenore connecting rod may be installed when the brazing materials 721a and 721b are attached to the guide Lenoles 5a and 5b. As described above, the lifting machine 6 is installed in the hoistway 1.

Next, the force applied to the lifting machine mounting mechanism 7 will be described. As shown in FIG. 3, a force F is applied to the driving sheave 6 a of the hoist 6 by the suspension means 10. Since the driving sheave 6a is arranged at a position shifted from the frame 711, a moment acts on the lifting machine mounting portion 71 via the lifting machine 6 by this force F. This moment is applied to the installation position of the lifting machine mounting part 71 and the rail mounting part 72, that is, at the positions of the guide parts 81a and 82a and the guide parts 81b and 82b, respectively, and the guide rails 5a and 5b and the rail mounting part, respectively. A reaction force is applied to 72. As a result, a bending moment is generated in the longitudinal direction including the guide portions 81a and 82a and the guide portions 81b and 82b in the guide rails 5a and 5b and the rail mounting portion 72, respectively.

[0032] Also, the guide rails 5a, 5b are attached to the hoistway wall, that is, the rails 53a and 53c and the rail brackets 53b and 53d are included in the range including the guide rail 5a, Bending moment acts on 5b. The rail mounting portion 72 is attached to the guide rails 5a and 5b across the range including the mounting interval of the hoistway walls of the guide rails 5a and 5b. In this range, the rail mounting portion 72 is also bent. Moment acts.

[0033] As described above, the hoisting machine mounting mechanism 7 in the first embodiment includes the hoisting machine mounting part 71 for mounting the hoisting machine 6 and the rail for mounting the hoisting machine mounting part 71 to the guide rails 5a and 5b. The rail mounting part 72 is attached to the lifting machine mounting part 71 within the longitudinal range of the guide rails 5a and 5b, and is installed in the longitudinal direction of the guide rails 5a and 5b. It is attached to the guide rails 5a and 5b across the attachment range of the portion 71. As a result, the cross-sectional performance of the lifting machine mounting mechanism 7 in the mounting range of the lifting machine mounting portion 71 in the longitudinal direction of the guide rails 5a and 5b is improved as compared with the case where only the guide rails 5a and 5b are used. Therefore, it is possible to reduce the bending moment acting on the guide rails 5a and 5b equivalently.

[0034] Further, the rail attachment portion 72 is attached to the guide rails 5a and 5b so as to substantially span the range including the attachment interval of the hoistway walls of the guide rails 5a and 5b. As a result, the cross-sectional performance of the lifting machine mounting mechanism 7 in this range is only for the guide rails 5a and 5b. improves. Therefore, the bending moment acting on the guide rails 5a and 5b can be reduced equivalently.

[0035] Further, the guide lenores 5a and 5b have rail mounting surfaces 55a and 55b opposite to the lenore guide rods 52a and 52b on the lenole bottom rods 51a and 51b, and the rail mounting portion 72 has the rail mounting surface 55a. Attached to 55b. Accordingly, since the rail guide portions 52a and 52b are not hindered in the mounting of the rail mounting portion 72 to the guide rails 5a and 5b, the rail mounting portion 72 can be configured with a simple structure and can be easily mounted.

[0036] Further, the lifting machine mounting portion 71 is provided with guide parts 81a, 82a, 81b, 82b that are slidable on the guide rails 5a, 5b. When the 71 is installed at a predetermined height in the hoistway 1, it is guided by the guide rails 5a and 5b, so that the lifting weight can be stabilized and the installation work can be facilitated.

The guide parts 81a and 82a and the guide parts 81b and 82b are attached to the lifting machine mounting part 71 so as to be detachable from the members 721a and 721b on the projection viewed from the upward force. 814, 824. Accordingly, it is possible to lift the lifting machine mounting portion 71 in a state where a gap is generated between the member 721a and the member 721b and the gap between the guide portions 81a and 82a and the guide portions 81b and 82b. Therefore, the installation work can be facilitated without the force S being twisted with the saddle members 721a, 721b and the guide rods 81a, 82a, 81b, 82b.

[0037] Further, since the guide portions 81a, 82a, 81b, and 82b are configured to be attached to the rail attachment portion 72, the guide portions 81a, 82a, 81b, and 82b can be shared as a fixing member to reduce the number of parts. it can. Further, the guide portions 81a, 82a, 81b, 82b can be attached to the rail attachment portion 72 at an arbitrary position, and the attachment height of the lifting machine 6 can be freely selected.

[0038] For example, in the case of a building where the top of the hoistway 1 is high, the upper ends of the guide rails 5a, 5b are supported by the building beams at the top of the hoistway 1, so the upper ends of the guide rails 5a, 5b also need to be raised. is there . At this time, if the installation position of the lifting machine 6 is uniform from the upper ends of the guide rails 5a and 5b, the lifting machine 6 is also installed at a higher position in the hoistway 1, so installation workers and maintenance workers are required. You will work at a higher position. In the present embodiment, since the installation height of the lifting machine 6 can be freely selected, installation work, maintenance work and the like that do not require installation of the lifting machine 6 higher than necessary are facilitated. [0039] Since the guide parts 81a, 81b, 82a, 82b are attached to the rail attaching part 72, and the lifting machine 6 is attached to the lifting machine attaching part 71 via the elastic bodies 7 15a, 715b, 716a, 716b. As a result, it is possible to obtain an anti-vibration effect of suppressing the vibration generated in the upper machine 6 from propagating to the guide rails 5a and 5b. In addition, the elastic bodies 715a, 715b, 716a, 716b attached to the lifting machine 6 that do not need to provide vibration isolation between the guide portions 81a, 82a, 81b, 82b and the guide rails 5a, 5b are required. The vibration isolation effect can be obtained with a few configurations.

[0040] Further, the vibration in the direction of arrow J in FIG. 3 due to the vibration of the hoisting machine 6 is supported by elastic bodies 715a, 715b, 716a, 716b arranged above and below the hoisting machine 6. Can be improved. Although two elastic bodies are provided on the upper and lower sides of the lifting machine 6, respectively, the invention is not limited to this, and a configuration in which one elastic body is provided at the upper center of the lifting machine and one elastic body is provided at the lower center. It is also possible to provide three or more elastic bodies on the top and bottom.

[0041] Further, the hoisting machine mounting mechanism 7 has the rail connecting portion 73 that connects the guide rails 5a and 5b to each other on the upper side of the guide rails 5a and 5b. Opening can be prevented, and a highly reliable elevator apparatus can be obtained. The rail connecting portion 73 may be attached directly to the upper portions of the guide rails 5a and 5b directly by the force attached to the members 721a and 721b.

[0042] Further, the rail mounting portion 72 has contact portions 722a and 722b that overlap with the upper ends of the guide rails 5a and 5b in the projection in which the upward force is also viewed, and the rail mounting portion 72 includes the contact portions 722a, 722b is attached in contact with the upper ends of the guide rails 5a and 5b. As a result, even if the rail mounting part 72 and the guide rails 5a and 5b are loosened, the force F applied to the lifting machine 6 is supported by the contact parts 722a and 722b. High elevator equipment can be obtained.

[0043] Even when the contact portions 722a and 722b are attached 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 not fastened. As a result, the rail mounting part 72 may move downward, but the force F applied to the hoisting machine 6 is supported by the hooking force on the upper ends of the contact parts 722a, 722b force guide rails 5a, 5b. An elevator apparatus with high reliability can be obtained.

[0044] Further, for example, mounting holes are provided in the guide rails 5a and 5b, and bolts are passed through the mounting holes. In the case of bolt fastening that is fastened to one mounting portion 72, the force F applied to the lifting machine 6 is supported by the bolt engaging with the mounting hole even if the fastening slips. In this case, the guide rails 5a and 5b are not only forced to cover the mounting holes, but the cross-sectional performance of the guide rails 5a and 5b in these mounting holes is reduced, and the strength of the guide rails 5a and 5b is reduced. To do. However, according to the present embodiment, since the force F applied to the lifting machine 6 is supported by the contact portions 722a and 722b, the strength that does not need to cover the mounting holes in the guide rails 5a and 5b is reduced. Never to

[0045] In addition, since the suspension means attachment portion 12 for attaching the suspension means 10 is provided in the lifting machine attachment portion 71, a separate member for attaching the suspension means is unnecessary, and the number of parts can be reduced. Also, if a beam is provided on the guide rails 5a and 5b and the lifting machine 6 is installed on the beam, the height direction of the ascending / descending path 1 is required. 6 and the lifting machine mounting portion 71 are installed within the longitudinal range of the guide rails 5a and 5b, so that the lifting machine 6 can be installed without increasing the height direction of the hoistway 1.

In the present embodiment, the lifting machine mounting portion 71 is arranged within the longitudinal range of the guide rails 5a and 5b in view of the horizontal force. May be placed out of the longitudinal range of 5b.

[0046] Embodiment 2.

12, FIG. 13, FIG. 14, FIG. 15 and FIG. 16 show a lifting machine mounting mechanism for an elevator apparatus according to Embodiment 2 of the present invention. FIG. 12 is a front view, and FIG. It is a cross section EE in FIG. 14 is a front view of an enlarged view of the main part of the upper part of the lifting machine mounting mechanism, FIG. 15 is a side view, and FIG. 16 is a view showing a cross section GG of FIG. The second embodiment is different from the first embodiment in that a partial contact portion 74, a restricting body 75, and an adjusting member 76 are provided on the upper portion of the rail mounting portion 72. The other points are the same as in the first embodiment, and a description thereof will be omitted. Note that the same reference numerals as those in Embodiment 1 denote the corresponding parts.

[0047] The partial contact portion 74, the limiting body 75, and the adjustment member 76 on the guide rail 5a side will be described with reference to FIGS. 14, 15, and 16. FIG. In the figure, a partial contact portion 74 is provided between the contact portion 722a of the rail mounting portion 72 and the upper end of the guide rail 5a. Further, the partial contact portion 74 overlaps with a part of the center of the upper end of the guide rail 5a on the projection viewed from above. Has been placed. Further, the partial contact portion 74 is attached to the contact portion 722a.

The restricting body 75 is composed of a rod-like restricting body, for example, a pair of bolts 75a and 75b, and is provided on the upper portion of the rail mounting portion 72. The bottom surfaces of the bolts 75a and 75b are located below the upper end of the guide rail 5a, and the bolts 75a and 75b are provided on both sides of the guide portion 52a of the guide rail 5a. Thereby, the restricting body 75 restricts the horizontal movement of the rail mounting portion 72. Bonoleto 75a and 75b are hoofed together with a Lenore connecting rod at the abutment rod 722a!

[0049] The adjustment member 76 is disposed between the contact portion 722a and the upper end of the guide rail 5a, and is formed in a plate shape. Here, the adjustment member 76 is disposed between the partial contact portion 74 and the upper end of the guide rail 5a. Due to the assembly error of the guide rail 5a, an error may occur in the distance between the contact portion 722a and the upper end of the guide rail 5a. At this time, a number of adjusting members 76 corresponding to the error in the interval are arranged, and the interval between the contact portion 722a and the upper end of the guide rail 5a is adjusted. Further, a hole is formed in the adjusting member 76, and bolts 75a and 75b are passed through the hole. Note that the guide rail 5b side is configured in the same manner as the force guide rail 5a side whose description is omitted.

As described above, the hoisting machine mounting mechanism 13 in the second embodiment is provided between the upper contact portions 722a and 722b of the rail mounting portion 72 and the upper ends of the guide rails 5a and 5b. Further, the partial contact portion 74 is disposed so as to overlap with a central portion of the upper ends of the guide rails 5a and 5b on the projection viewed from the upward force. As a result, when the contact portions 722a and 722b support the force F exerted on the lifting machine 6, even if the shape accuracy of the upper end surfaces of the guide rails 5a and 5b is poor, the contact portions 722a and 722b are provided on the contact portions 722a and 722b. Since the partial contact portion 74 is in contact with the central portion of the guide rails 5a and 5b, an offset load acts on the rail mounting portion 72. Usually, the height of the hoistway is caused by construction errors. Therefore, the upper ends of the guide rails 5a and 5b are cut at the installation site according to the height of the hoistway. In general, the shape accuracy of the cut surface is poor, but according to the second embodiment, even if this shape accuracy is poor, it can be handled with a simple configuration, so it is economical and easy to install. Is obtained.

[0051] Further, the restricting body 75 is provided on the upper portion of the rail mounting portion 72, and bolts 75a and 75b as the limiting body 75 are arranged on both sides of the rail guide portions 52a and 52b, respectively. Movement is restricted. This should prevent the rail mounting part 72 and the guide rail 5 When the clip 54 that fastens a and 5b is released, the members 721a and 721b try to move in the direction perpendicular to the interval between the guide rails 5a and 5b. Bolts 75a and 75b are the rail guides 52a and 52b. The movement of the members 721a and 721b is restricted by contacting the side surface of 52b. Therefore, the abutting portions 722a and 722b are not released in the vertical direction in the interval direction of the guide rails 5a and 5b, and the rail mounting portion 72 can reliably support the force F applied to the lifting machine 6 and has high reliability. A lift device can be obtained.

[0052] Further, the adjustment member 76 is disposed between the upper ends of the guide rails 5a and 5b and the contact portions 722a and 722b, and the interval between the upper ends of the guide rails 5a and 5b and the contact portions 722a and 722b is increased. By adjusting, even if there is an assembly error of the guide rails 5a and 5b, the rail mounting part 72 can be accurately mounted in the height direction and the contact parts 722a and 722b are supported by the guide rails 5a and 5b. The force F applied to the lifting machine 6 can be reliably supported. The adjusting member 76 is not limited to the force disposed between the partial contact portion 74 and the upper ends of the guide rails 5a and 5b. The partial contact portion 74 may be in contact with the upper ends of the guide rails 5a and 5b, and the adjustment member 76 may be disposed between the contact portions 721a and 721b and the partial contact portion 74. Further, the adjusting member 76 may be disposed between the contact portions 722a and 722b and the upper ends of the guide rails 5a and 5b in a state where the partial contact portion 74 is not provided.

[0053] Further, a hole is formed in the adjustment member 76, and bolts 75a and 75b as rod-shaped restricting bodies pass through the hole. As a result, in the unlikely event that the rail mounting portion 72 and the guide rails 5a and 5b are loosened, the adjusting member 76 remains engaged with the force bolts 75a and 75b to be removed, and can be prevented from falling off. Therefore, the rail mounting portion 72 can reliably support the force F applied to the lifting machine 6 while maintaining the installation height of the lifting machine 6, and a more reliable elevator device can be obtained.

[0054] In the present embodiment, the bolts 75a and 75b as the restricting body 75 are provided on both sides of the guide portions 52a and 52b. For example, the bolts 75a and 75b may be provided on both sides of the rail bottom portions 51a and 51b. Even in this case, since the bolts 75a and 75b come into contact with the side surfaces of the rail bottom portions 51a and 51b to restrict the movement of the rail mounting portion 72, the contact portions 722a and 722b are perpendicular to the interval direction of the guide rails 5a and 5b. Never come off.

[0055] In addition to the configuration in which the bolts 75a and 75b of the limiting body are provided on both sides of the rail guide portions 52a and 52b, a configuration in which the limiting body is also provided on the head side of the rail guide portions 52a and 52b may be adopted. . this In this case, the restriction bodies provided on both sides of the rail guide portions 52a and 52b restrict the movement of the rail mounting portion 72 in the direction perpendicular to the interval between the guide rails 5a and 5b. The restricting body provided on the head side of the rail guide portions 52a and 52b restricts the movement of the guide rails 5a and 5b of the rail mounting portion 72 in the interval direction. Therefore, the rail mounting portion 72 in which the contact portions 722a and 722b are not released in the direction perpendicular to the interval direction of the guide rails 5a and 5b can support the force F applied to the lifting machine 6 more reliably.
