Note that in each drawing, some of the components may be omitted in order to facilitate understanding.

[0010] Terms including ordinal numbers such as first, second, etc. are used to describe various components, but these terms are used only for the purpose of distinguishing one component from another, and the components are not particularly limited by these terms. The number of components including ordinal numbers is not particularly limited, and may be, for example, one. In addition, the ordinal numbers used in the following specification and drawings may differ from the ordinal numbers described in the claims.

[0011] Hereinafter, an embodiment of a support device and a 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 the guide device for an elevator lifting machine, and does not limit the configuration of the support device and the guide device for an elevator lifting machine.

[0012] Here, before describing the configurations of the support device and guide device for the elevator lifting machine, the elevator hoistway X1 will be described.

[0013] 1, the hoistway X1 may include entrances X2-X4 penetrating in the first horizontal direction D1 to communicate the inside of the hoistway X1 with the landings Y1-Y3, an upper wall X5 disposed above the entrances X2-X4 and facing the landings Y1-Y3, and a side wall X6 disposed to the side of the entrances X2-X4 in the second horizontal direction D2 and facing the landings Y1-Y3. As a result, the entrances X2-X4 are partitioned by the upper wall X5 and the side wall X6.

[0014] 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 an entrance X4 (only one is shown in FIG. 1) between the first entrance X2 and the second entrance X3 is referred to as the third entrance X4. In the future, landing doors (not shown) will be installed at the entrances X2 to X4.

[0015] In addition, the topmost landing Y1 is referred to as the first landing Y1, the bottommost landing Y2 is referred to as the second landing Y2, and a landing Y3 (only one is shown in FIG. 1) between the first landing Y1 and the second landing Y2 is referred to as 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.

[0016] 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 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.

[0017] Although not particularly limited, for example, as in this embodiment, the lifting machines 21, 22 may include 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.

[0018] Each of the lifting machines 21, 22 may include, for example, as in this embodiment, 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 a material (for example, a part constituting an elevator) Z1 is suspended and which is raised and lowered by the lifting main body 21a, 22a. Although not shown, each of the lifting machines 21, 22 may include, for example, an operating part (for example, a chain, a remote control, etc.) for raising and lowering the suspending part 21c, 22c.

[0019] 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.

[0020] 2 to 6, the device main body 2 may include, for example, vertical members 4 extending in the up-down direction D3, horizontal members 5 extending in the first horizontal direction D1, and diagonal members 6 connecting the vertical members 4 and the horizontal members 5. The diagonal members 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 hooked.

[0021] Also, for example, as in this embodiment, the upper wall X5 disposed 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 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 body part 2 and the clamping part 8.

[0022] 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 located above the upper end of the first entrance X2. Note that, for example, as in this embodiment, it is preferable that the suspending portion 22c of the second lifting machine 22 can be raised to a position above the upper end of the first entrance X2.

[0023] 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. Note that the base end of the insertion portion 7 may be fixed to the vertical member 4 of the device body 2, for example, 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.

[0024] 3 to 6, the insertion section 7 may have, for example, at its tip, a rope connection section 7a to which a rope 23 (see Figs. 9 and 10) is connected. The rope 23 includes all rope-like, string-like and rope-like objects such as a wire rope and a chain rope (a rope formed from a chain).

[0025] Although not particularly limited, each component of the supporting device 1 may be formed of metal (e.g., steel, stainless steel) as in this embodiment. This provides rigidity to each component of the supporting device 1. Although not particularly limited, the device main body 2 may have a plurality of openings (lightening holes) to reduce weight.

[0026] 3 and 4, the device body 2 may include, for example, an operation connector 6b connected to a tip 24a of a long operating tool 24. For example, as in this embodiment, the operation connector 6b may be provided on the diagonal member 6 of the device body 2.

[0027] Although not particularly limited, for example, as in this embodiment, the tip 24a of the operating tool 24 may be a protrusion, and the operation 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. As a result, the operating tool 24 is detachable from the device main body 2 and rotatably connected to the device main body 2. However, without being limited to such a configuration, for example, the tip 24a of the operating tool 24 may be a cylinder, and the operation connection part 6b may be a protrusion inserted into the tip 24a of the operating tool 24.

[0028] 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 main body portion 12 to which the guide tube 11 is fixed, and a guide portion 13 that guides the rope 23.

[0029] 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 portion 7 as in this embodiment. The length dimension of the guide tube 11 may be, for example, in this embodiment, equal to or smaller than the thickness dimension of the upper wall X5, i.e., equal to or smaller than the length dimension of the through hole X5a.

[0030] The guide main body 12 may include, for example, 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 main body 12 are clamped between the device main body 2 and the clamping portion 8, so that with the insertion portion 7 inserted into the guide tube 11, the guide device 10 is fixed to the upper wall X5 together with the support device 1 (see FIGS. 2 and 3).

[0031] The guide portion 13 may include, for example, a rotating body 13a rotatably connected to the guide body 12 as in this embodiment. The rotating body 13a may guide the rope 23 by having the rope 23 wound around its outer periphery as in this embodiment (see Figs. 9 and 10).

[0032] As a result, the rotor 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 lateral direction D2, the inclination angle with respect to the axial direction of the guide tube 11 is 30° or less, and for example, it is preferable that the inclination angle with respect to the axial direction of the guide tube 11 is 10° or less.

[0033] 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 a plurality of openings (hollowed-out portions) to reduce weight, as in this embodiment.

[0034] The configurations of the support device 1 and the guide device 10 according to this embodiment have been described above, and next, a method for fixing the support device 1 according to this embodiment to the elevator shaft X1 will be described with reference to Figs. 9 to 12. Note that the following description is provided as an example to aid in understanding the fixing method of the support device 1, and is not intended to limit the fixing method of the support device 1, etc.

[0035] 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 an 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.

[0036] 10, the tip end 24a of the operating tool 24 is connected to the device body 2, and the worker at the first landing Y1 holds the base end 24b of the operating tool 24 and pulls the rope 23 while lifting the device body 2. As a result, the rope 23 is guided by the guide tube 11, so that the rope 23 is prevented from directly contacting the through hole X5a. Therefore, the rope 23 can be pulled smoothly.

[0037] Moreover, since the rotor 13a guides the rope 23 wound around its outer periphery, 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 rotor 13a. Therefore, the rope 23 can be pulled even more smoothly.

[0038] 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 (rope connection portion 7a) of the insertion portion 7 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.

[0039] 11, the clamping portion 8 is fixed to the insertion portion 7, so that the clamping portion 8 and the device main body 2 sandwich the guide device 10 and the upper wall X5, and therefore 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, the worker at the first landing Y1 may fix the clamping portion 8 to the insertion portion 7 using a stepladder or the like.

[0040] 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, it is not necessary 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.

[0041] Thereafter, the first lifting machine 21 lifts up the second lifting machine 22, so that the heavy second lifting machine 22 is connected to the device main body 2 via the light first lifting machine 21, as shown in Fig. 12. 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 suppress limitations on the height of materials Z1 that can be carried in and out through the first entrance / exit X2.

[0042] For example, since the suspending portion 22c of the second lifting machine 22 can be raised to a position above the upper end of the first entrance X2, for example, the entire first entrance X2 can be used as an entrance for carrying in and out the material Z1. This allows, for example, even a large material Z1 located at the second landing Y2 (see FIG. 1) to be carried into the first landing Y1 via the first entrance X2.

[0043] 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 further preferably, for example, 1,500 mm or more.

[0044] Moreover, since the support device 1 is fixed to the upper wall X5, the materials Z1 transported inside the elevator shaft X1 by the second lifting machine 22 ascend and descend near the entrances X2 to X4. Therefore, the materials Z1 can be easily transported in and out through the entrances X2 to X4.

[0045] Although not particularly limited, the distance of the attachment portion 6a of the device body 2 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 of the attachment portion 6a of the device body 2 from the upper wall X5 in the first horizontal direction D1 is preferably, for example, 200 mm or more.

[0046] [1] As described above, the method for fixing the support device 1 of the elevator lifting machine 21, 22 is as follows, as in this embodiment: A method for fixing a support device 1 for an elevator lifting machine 21, 22 to a hoistway X1, comprising the steps of: The elevator shaft X1 is Entrances X2 to X4 communicating the inside of the elevator X1 with the landings Y1 to Y3; An upper wall X5 is disposed above the entrances X2 to X4 and faces the landings Y1 to Y3, The upper wall X5 has a through hole X5a. The supporting device 1 is An apparatus main body 2 disposed inside the elevator shaft X1 and connected to the lifting machine 21; a fixing portion 3 for fixing the device main body portion 2 to the upper wall X5, The fixed portion 3 includes an insertion portion 7 that is fixed to the device body 2 and is inserted into the through hole X5a, The fixing method includes: Inserting a cylindrical guide tube 11 of a guide device 10 into the through hole X5a; Inserting a rope 23 into the guide tube 11 and connecting the rope 23 to the insertion portion 7; Pulling the rope 23 so that the guide tube 11 guides the rope 23; Inserting the insertion portion 7 into the through hole X5a and fixing the device main body portion 2 to the upper wall X5 by the fixing portion 3. This method is preferred.

[0047] According to this method, the insertion portion 7 is connected to the rope 23 inserted into the guide tube 11. Then, the rope 23 is pulled so that the rope 23 is guided into the guide tube 11, and then the insertion portion 7 is inserted into the through hole X5a. Then, the fixing portion 3 fixes the device main body 2 to the upper wall X5, so that the support device 1 can be fixed at a position above the entrance / exit X2.

[0048] [2] In addition, the method of fixing the support device 1 of the elevator lifting machine 21, 22 described above in [1] is as follows, as in this embodiment: 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.

[0049] According to 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.

[0050] [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.

[0051] According to such a configuration, the rope 23 can be guided by the guide pipe 11. And, the support device 1 can be fixed at a position above the entrance X2.

[0052] [4] In addition, the guide device 10 described above in [3] is, as in this embodiment, Further provided is a guide portion 13 for guiding the rope 23 so that the rope 23 extends from the guide tube 11 along the axial direction of the guide tube 11. This configuration is preferred.

[0053] According to such a configuration, since the guide portion 13 guides the rope 23, the rope 23 extends from the guide tube 11 along the axial direction of the guide tube 11. As a result, the rope 23 is smoothly guided by the guide tube 11.

[0054] [5] In addition, the guide device 10 of [4] above, as in this embodiment, The guide pipe 11 is fixed to a guide body 12. The guide portion 13 includes a rotor 13a around whose outer periphery the rope 23 is wound and which is rotatably connected to the guide body portion 12. This configuration is preferred.

[0055] According to this configuration, the rotating body 13a is rotatably connected to the guide main body 12, and the rope 23 is wound around the outer periphery of the rotating body 13a. 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.

[0056] [6] In addition, the guide device 10 according to any one of the above items [3] to [5] may be configured as follows: The length dimension of the guide tube 11 is equal to or less than the thickness dimension of the upper wall X5. This configuration is preferred.

[0057] According to this configuration, the length dimension of the guide tube 11 is equal to or smaller than the thickness dimension of the upper wall X5, so that the guide tube 11 does not protrude from the upper wall X5. As a result, for example, the insertion portion 7 can be moved to the through-hole X5a while the tip of the insertion portion 7 is guided by the upper wall X5.

[0058] [7] In addition, the supporting 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], This configuration is preferred.

[0059] According to such a configuration, the support device 1 can be fixed at a position above the entrance X2.

[0060] The fixing method of 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 above-mentioned embodiment, and are not limited to the above-mentioned action and effect. Furthermore, the fixing method of 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 possible to arbitrarily select one or more of the configurations and methods according to the various modified examples described below and adopt them in the configurations and methods according to the above-mentioned embodiment.

[0061] (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. For example, the guide device 10 may be configured not to include a section that guides the rope 23 in addition to the guide tube 11.

[0062] (B) In the guide device 10 according to the above embodiment, the guide unit 13 is configured to include a rotor 13a around which the rope 23 is wound and which is rotatably connected to the guide body 12. However, the guide device 10 is not limited to this configuration. For example, the guide unit 13 may be configured to include a guide plate that is fixedly attached to the guide body 12.

[0063] (C) In the guide device 10 according to the above embodiment, the length of the guide tube 11 is equal to or smaller than the thickness of the upper wall X5. However, the guide device 10 is not limited to this configuration. For example, the length of the guide tube 11 may be greater than the thickness of the upper wall X5.

[0064] (D) In ​​addition, in the support device 1 according to the above embodiment, the device main body 2 is indirectly connected to the second lifting machine 22 that transports the material Z1 via the first lifting machine 21. However, the support device 1 is not limited to such a configuration. For example, the device main body 2 may be directly connected to the lifting machine that transports the material Z1.

[0065] (E) In addition, in the fixing method of the support device 1 according to the above embodiment, the device main body 2 is fixed to the upper wall X5 with the insertion portion 7 inserted into the guide tube 11. That is, the support device 1 is fixed to the upper wall X5 together with the guide device 10. However, the fixing method of the support device 1 is not limited to this method.

[0066] For example, as shown in Fig. 13 and Fig. 14, the support device 1 may be fixed to the upper wall X5 in a state in which the guide device 10 is removed from the upper wall X5. For example, in the fixing method of the support device 1 shown in Fig. 13, the insertion part 7 is directly inserted into the through hole X5a, and the clamping part 8 and the device main body 2 clamp the upper wall X5.

[0067] (F) In addition, in the fixing method of the support device 1 according to the above embodiment, the clamping unit 8 and the device body 2 clamp the upper wall X5. Specifically, the clamping unit 8 and the device body 2 clamp the upper wall X5 and the guide device 10. However, the fixing method of the support device 1 is not limited to this method.

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

[0069] (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 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 X2.

[0070] (H) The method of fixing the support device 1 according to the above embodiment is a method of using the operation 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 that does not use the operation tool 24.
