Below, one embodiment of the support device and guide device for an elevator lifting machine will be described with reference to Figures 1 to 12. Note that the following embodiment is provided as an example to aid in understanding the configuration of the support device and guide device for an elevator lifting machine, and does not limit the configuration of the support device and guide device for an elevator lifting machine.

Before describing the configurations of the support device and guide device of the elevator lifting machine, we will now describe the elevator hoistway X1.

As shown in FIG. 1, for example, the elevator shaft X1 may have entrances X2 to X4 that penetrate in the first horizontal direction D1 and communicate between the interior of the elevator shaft X1 and the landings Y1 to Y3, a top wall X5 that is disposed above the entrances X2 to X4 and faces the landings Y1 to Y3, and a side wall X6 that is disposed to the side of the entrances X2 to X4 in the second horizontal direction D2 and faces the landings Y1 to Y3. As a result, the entrances X2 to X4 are partitioned by the top wall X5 and the side wall X6.

The top entrance X2 is referred to as the first entrance X2, the bottom entrance X3 is referred to as the second entrance X3, and the entrance X4 between the first entrance X2 and the second entrance X3 (only one is shown in FIG. 1) is referred to as the third entrance X4. In the future, landing doors (not shown) will be installed at the entrances X2 to X4.

The topmost landing Y1 is called the first landing Y1, the bottommost landing Y2 is called the second landing Y2, and the landing Y3 between the first landing Y1 and the second landing Y2 (only one is shown in FIG. 1) is called the third landing Y3. Although not particularly limited, for example, as shown in FIG. 1, a machine room may be provided above the elevator shaft X1.

As shown in Figures 1 and 2, the support device 1 is fixed to the elevator shaft X1 together with the guide device 10, for example, and supports the lifting machines 21, 22. The support device 1 may also include, for example, an apparatus main body 2 to which the lifting machines 21, 22 are connected, and a fixing part 3 that fixes the apparatus main body 2 to the elevator shaft X1, as in this embodiment.

For example, as in this embodiment, the lifting machines 21, 22 may include, but are not limited to, a first lifting machine 21 attached to the device main body 2 and a second lifting machine 22 attached to the first lifting machine 21. That is, the first lifting machine 21 is directly connected to the device main body 2, and the second lifting machine 22 is indirectly connected to the device main body 2 via the first lifting machine 21.

Each lifting machine 21, 22 may, for example, as in this embodiment, have a lifting main body 21a, 22a, a hook 21b, 22b for attaching the lifting main body 21a, 22a, and a suspending part 21c, 22c to which material (e.g., a part that constitutes an elevator) Z1 is suspended and raised and lowered by the lifting main body 21a, 22a. Although not shown, each lifting machine 21, 22 may, for example, have an operating part (e.g., a chain, a remote control, etc.) for raising and lowering the suspending part 21c, 22c.

Although not particularly limited, the first lifting machine 21 may be, for example, a manual chain block, and the second lifting machine 22 may be, for example, an electric chain block. And, for example, as in this embodiment, the weight of the first lifting machine 21 may be lighter than the weight of the second lifting machine 22.

As shown in Figures 2 to 6, the device main body 2 may include, for example, a vertical member 4 extending in the up-down direction D3, a horizontal member 5 extending in the first horizontal direction D1, and a diagonal member 6 connecting the vertical member 4 and the horizontal member 5. The diagonal member 6 may include, for example, as in this embodiment, a mounting portion 6a to which the first lifting machine 21 is attached. Although not particularly limited, the mounting portion 6a may be, for example, as in this embodiment, a through hole to which the hook portion 21b of the first lifting machine 21 is hung.

Also, for example, as in this embodiment, the upper wall X5 located above the first entrance X2 may have a through hole X5a penetrating in the first horizontal direction D1. And, for example, as in this embodiment, the fixing part 3 may have an insertion part 7 fixed to the device main body part 2 and inserted into the through hole X5a, and a clamping part 8 fixed to the insertion part 7 and clamping the upper wall X5 and the guide device 10 between the device main body part 2.

As a result, the device main body 2 is disposed inside the elevator shaft X1 and fixed to the upper wall X5, so that the device main body 2 is positioned above the upper end of the first entrance/exit X2. Note that, for example, as in this embodiment, it is preferable that the hanging portion 22c of the second lifting machine 22 can be raised to a position above the upper end of the first entrance/exit X2.

Although not particularly limited, for example, as in this embodiment, the insertion portion 7 may have a male thread (e.g., a long screw), and the clamping portion 8 may be a female thread material (e.g., a nut) that screws into the male thread. The base end of the insertion portion 7 may be fixed to the vertical member 4 of the device body 2, as in this embodiment. In this way, the clamping portion 8 and the vertical member 4 clamp the upper wall X5 and the guide device 10, and the device body 2 and the guide device 10 are fixed to the upper wall X5.

As shown in Figures 3 to 6, the insertion section 7 may have, for example, a rope connection section 7a at the tip to which a rope 23 (see Figures 9 and 10) is connected. The rope 23 includes all rope-like, string-like, and cord-like objects, such as a wire rope or a chain rope (a rope formed from a chain).

Although not particularly limited, each component of the support device 1 may be formed of metal (e.g., steel, stainless steel), as in this embodiment. This provides each component of the support device 1 with rigidity. Although not particularly limited, the device main body 2 may have multiple openings (holes) to reduce weight, for example.

As shown in Figs. 3 and 4, the device body 2 may include an operation connection part 6b that is connected to the tip 24a of the long operating tool 24. For example, as in this embodiment, the operation connection part 6b may be provided on the diagonal member 6 of the device body 2.

And, for example, as in this embodiment, the tip 24a of the operating tool 24 may be a protrusion, and the operating connection part 6b of the device main body 2 may be a cylinder having a through hole into which the protrusion of the tip 24a of the operating tool 24 is inserted. In this way, the operating tool 24 is detachable from the device main body 2, and is rotatably connected to the device main body 2. However, this is not limited to such a configuration, and for example, the tip 24a of the operating tool 24 may be a cylinder, and the operating connection part 6b may be a protrusion inserted into the tip 24a of the operating tool 24.

As shown in Figures 7 and 8, the guide device 10 may include, for example, a cylindrical guide tube 11 that guides the rope 23, a guide body portion 12 to which the guide tube 11 is fixed, and a guide portion 13 that guides the rope 23.

The guide tube 11 may be formed, for example, in a cylindrical shape as in this embodiment, or may be formed, for example, in a rectangular tube shape. The guide tube 11 may be formed, for example, in a size that allows it to be inserted into the insertion section 7 as in this embodiment. The length dimension of the guide tube 11 may be, for example, in this embodiment, less than the thickness dimension of the upper wall X5, i.e., less than the length dimension of the through hole X5a.

The guide body 12 may have a clamped portion 12a that is clamped by the clamping portion 8, as in this embodiment. As a result, the clamped portion 12a and the upper wall X5 of the guide body 12 are clamped between the device body 2 and the clamping portion 8, so that when the insertion portion 7 is inserted into the guide tube 11, the guide device 10 is fixed to the upper wall X5 together with the support device 1 (see Figures 2 and 3).

The guide section 13 may, for example, include a rotating body 13a rotatably connected to the guide body section 12 as in this embodiment. The rotating body 13a may, for example, guide the rope 23 by having the rope 23 wound around its outer periphery as in this embodiment (see Figures 9 and 10).

As a result, the rotating body 13a guides the rope 23, so that the rope 23 extends from the guide tube 11 to the landing Y1 side along the axial direction of the guide tube 11. Note that "along the axial direction of the guide tube 11" means that, for example, when viewed in the second horizontal direction D2, the inclination angle with respect to the axial direction of the guide tube 11 is 30° or less, and it is preferable that, for example, the inclination angle with respect to the axial direction of the guide tube 11 is 10° or less.

Although not particularly limited, each component of the guide device 10 may be formed of metal (e.g., steel, stainless steel) or hard resin, as in this embodiment. This provides rigidity to each component of the guide device 10. Although not particularly limited, the guide body 12 may have multiple openings (holes) to reduce weight, as in this embodiment.

The configuration of the support device 1 and guide device 10 according to this embodiment is as described above. Next, the method of fixing the support device 1 according to this embodiment to the elevator shaft X1 will be described with reference to Figures 9 to 12. Note that the following description is provided as an example to help understand the fixing method of the support device 1, and is not intended to limit the fixing method of the support device 1.

As shown in FIG. 9, the guide tube 11 of the guide device 10 is inserted into the through hole X5a of the upper wall X5. Then, the rope 23 is inserted into the guide tube 11, and the end of the rope 23 is connected to the rope connection part 7a of the insertion part 7. At this time, a worker (not shown) at the first landing Y1 may use a stepladder or the like to insert the guide tube 11 into the through hole X5a and insert the rope 23 into the guide tube 11. At this time, the first lifting machine 21 is connected to the device main body part 2.

Then, as shown in FIG. 10, the tip 24a of the operating tool 24 is connected to the device main body 2, and the worker at the first landing Y1 grasps the base end 24b of the operating tool 24 and pulls the rope 23 while lifting the device main body 2. This allows the rope 23 to be guided by the guide tube 11, preventing the rope 23 from coming into direct contact with the through hole X5a. Therefore, the rope 23 can be pulled smoothly.

In addition, the rotating body 13a guides the rope 23 wound around its outer circumference, so that the rope 23 extends from the guide tube 11 toward the landing X1 side along the axial direction of the guide tube 11 (see FIG. 9). As a result, the rope 23 is smoothly guided by the guide tube 11 and also by the rotating body 13a. This allows the rope 23 to be pulled even more smoothly.

In addition, since the length dimension of the guide tube 11 is equal to or less than the thickness dimension of the upper wall X5, the guide tube 11 does not protrude from the upper wall X5. This allows, for example, the insertion portion 7 to be moved to the through hole X5a and the guide tube 11 while the tip of the insertion portion 7 (rope connection portion 7a) is guided by the upper wall X5. Therefore, the insertion portion 7 can be easily inserted into the through hole X5a and the guide tube 11.

As shown in FIG. 11, the clamping portion 8 is fixed to the insertion portion 7, so that the clamping portion 8 and the device main body 2 clamp the guide device 10 and the upper wall X5, and the device main body 2 is fixed to the upper wall X5 inside the elevator shaft X1, and the guide device 10 is also fixed to the upper wall X5. At this time, a worker at the first landing Y1 may use a stepladder or the like to fix the clamping portion 8 to the insertion portion 7.

In this way, for example, a worker can fix the support device 1 to the elevator shaft X1 simply by performing work at the first landing Y1. In addition, since the guide device 10 is fixed to the upper wall X5 together with the support device 1, for example, there is no need to remove the guide device 10 from the upper wall X5, and there is also no risk of losing the guide device 10 during work, for example.

Then, the first lifting machine 21 lifts the second lifting machine 22, and as shown in FIG. 12, the heavy second lifting machine 22 is connected to the device main body 2 via the light first lifting machine 21. As a result, since the device main body 2 is located above the upper end of the first entrance/exit X2, it is possible to prevent restrictions on the height of materials Z1 that can be transported in and out through the first entrance/exit X2.

For example, since the hoisting portion 22c of the second lifting machine 22 can be raised to a position higher than the top end of the first entrance X2, the entire first entrance X2 can be used as an entrance for materials Z1. This allows, for example, even large materials Z1 located at the second landing Y2 (see FIG. 1) to be brought into the first landing Y1 via the first entrance X2.

Although not particularly limited, the distance that the mounting portion 6a of the device main body 2 is spaced upward from the upper end of the first entrance/exit X2 may be, for example, 500 mm or more, and is preferably, for example, 1,000 mm or more, and is even more preferably, for example, 1,500 mm or more.

In addition, because the support device 1 is fixed to the upper wall X5, the material Z1 transported inside the elevator shaft X1 by the second lifting machine 22 ascends and descends near the entrances X2 to X4. This makes it easy to transport the material Z1 in and out through the entrances X2 to X4.

Although not particularly limited, the distance that the mounting portion 6a of the device body 2 is separated from the upper wall X5 in the first horizontal direction D1 may be, for example, 800 mm or less, and is preferably, for example, 500 mm or less, and more preferably, for example, 300 mm or less. Although not particularly limited, the distance that the mounting portion 6a of the device body 2 is separated from the upper wall X5 in the first horizontal direction D1 is preferably, for example, 200 mm or more.

The method further includes inserting the insertion portion 7 into the guide tube 11, and fixing the device main body 2 to the upper wall X5 in a state in which the insertion portion 7 is inserted into the guide tube 11.
This method is preferred.

With this configuration, the insertion portion 7 is inserted into the guide tube 11. Then, with the insertion portion 7 inserted into the guide tube 11, the device main body 2 is fixed to the upper wall X5. As a result, the guide device 10 is also fixed to the upper wall X5 together with the support device 1.

[3]
In addition, the guide device 10, as in this embodiment,
Used in the fixing method of the support device 1 of the elevator lifting machine 21, 22 described above in [1] or [2],
This configuration is preferred.

With this configuration, the rope 23 can be guided by the guide tube 11. And the support device 1 can be fixed at a position above the entrance/exit X2.

[4]

This configuration is preferred.

With this configuration, the guide section 13 guides the rope 23, so that the rope 23 extends from the guide tube 11 along the axial direction of the guide tube 11. This allows the rope 23 to be smoothly guided by the guide tube 11.

[5]
In addition, the guide device 10 of the above [4] is as in this embodiment,

As a result, the rotating body 13a guides the rope 23, so that the rope 23 extends from the guide tube 11 along the axial direction of the guide tube 11. Therefore, the rope 23 is smoothly guided by the guide tube 11 and also by the rotating body 13a.

[6]
In addition, the guide device 10 according to any one of the above items [3] to [5] may be configured as follows:

With this configuration, the length dimension of the guide tube 11 is equal to or less than the thickness dimension of the upper wall X5, so the guide tube 11 does not protrude from the upper wall X5. This allows, for example, the tip of the insertion portion 7 to be guided by the upper wall X5 while the insertion portion 7 is moved to the through hole X5a.

[7]
In addition, the support device 1, as in this embodiment,
Used in the fixing method of the support device 1 of the elevator lifting machine 21, 22 described above in [1] or [2],

The method of fixing the support device 1 of the elevator lifting machine 21, 22, the guide device 10, and the support device 1 are not limited to the configuration of the embodiment described above, and are not limited to the above-mentioned effects. Furthermore, the method of fixing the support device 1 of the elevator lifting machine 21, 22, the guide device 10, and the support device 1 can be modified in various ways without departing from the gist of the present invention. For example, it is of course possible to arbitrarily select one or more of the configurations and methods related to the various modified examples described below and adopt them in the configurations and methods related to the embodiment described above.

(A) The guide device 10 according to the above embodiment is configured to include a guide section 13 that guides the rope 23 in addition to the guide tube 11. However, the guide device 10 is not limited to this configuration.

(E) In addition, in the method of fixing the support device 1 according to the above embodiment, the device body 2 is fixed to the upper wall X5 with the insertion portion 7 inserted into the guide tube 11. In other words, the support device 1 is fixed to the upper wall X5 together with the guide device 10. However, the method of fixing the support device 1 is not limited to this method.

For example, as shown in Figures 13 and 14, the support device 1 may be fixed to the upper wall X5 with the guide device 10 removed from the upper wall X5. For example, in the fixing method of the support device 1 shown in Figure 13, the insertion portion 7 is directly inserted into the through hole X5a, and the clamping portion 8 and the device main body 2 clamp the upper wall X5.

(F) In addition, in the fixing method of the support device 1 according to the above embodiment, the clamping portion 8 and the device main body portion 2 clamp the upper wall X5.

In this way, the support device 1 is fixed to the upper wall X5.

(G) In addition, in the fixing method of the support device 1 according to the above embodiment, the entire device body 2 is positioned above the upper end of the entrance/exit X2. However, the fixing method of the support device 1 is not limited to this method. For example, a part of the device body 2 may be positioned below the upper end of the entrance/exit X2.

(H) In addition, the method of fixing the support device 1 according to the above embodiment is a method of using the operating tool 24. However, the method of fixing the support device 1 is not limited to this method. For example, the method of fixing the support device 1 may be a method of not using the operating tool 24.

(I) In addition, the order of each task (step) in the method for fixing the support device 1 can be any order, so long as it does not involve using something that was done in a previous task. For example, even if the steps are described using "first" and "next" for convenience, this does not mean that this order is essential.
