[0009] Hereinafter, embodiments will be described with reference to the drawings. Embodiment 1 1 is a front view showing an elevator hoisting machine according to embodiment 1. In the figure, the elevator hoisting machine 1 has a hoisting machine body 2, a drive sheave 3, a suspension body stopper 4, and a pair of eyebolts 5.

[0010] The hoist main body 2 has a hoist motor 6 and a pair of hoist brakes 7. The hoist motor 6 rotates the drive sheave 3. The pair of hoist brakes 7 keep the drive sheave 3 stationary. The pair of hoist brakes 7 also brake the rotation of the drive sheave 3.

[0011] The drive sheave 3 is fixed to the rotor of the hoist motor 6 by a plurality of sheave fixing bolts 8. A suspension body (not shown) is wound around the drive sheave 3. In the elevator after installation, a car (not shown) and a counterweight (not shown) are suspended by the suspension body, and are raised and lowered by rotating the drive sheave 3. A plurality of main ropes or a plurality of belts are used as the suspension body.

[0012] The suspended body stopper 4 is fixed to the front of the hoist body 2 by a plurality of stopper fixing bolts 9. The suspended body stopper 4 prevents the suspended body from coming off the drive sheave 3.

[0013] The pair of eyebolts 5 are attached to the upper part of the hoisting machine body 2. For example, when the elevator hoisting machine 1 is transported, the pair of eyebolts 5 are used to lift the elevator hoisting machine 1.

[0014] FIG. 2 is a front view showing the elevator hoisting machine 1 of FIG. 1 in a state where the installation auxiliary device according to the first embodiment is attached.

[0015] The installation aid includes a rope drum 11, a lifting rope 12, a connector 13, a guide member 14, and a balance weight 15.

[0016] The rope drum 11 is fixed to the drive sheave 3. The rope drum 11 is rotated integrally with the drive sheave 3 around the rotation center of the drive sheave 3 by the hoisting machine motor 6. The inner diameter of the rope drum 11 is larger than the outer diameter of the drive sheave 3, and the rope drum 11 is placed over the drive sheave 3.

[0017] The lifting rope 12 is wound onto the rope drum 11 as the rope drum 11 rotates. In FIG. 2, most of the lifting rope 12 is wound onto the rope drum 11, and only the tip of the lifting rope 12 is pulled out from the rope drum 11. The connector 13 is connected to the tip of the lifting rope 12.

[0018] The guide member 14 is fixed to the hoisting machine body 2 by a plurality of guide member bolts 18. Furthermore, the guide member 14 guides the lifting rope 12 to the rope drum 11 when the lifting rope 12 is wound onto the rope drum 11. Furthermore, the guide member 14 guides the lifting rope 12 to the withdrawal port when the lifting rope 12 is withdrawn from the rope drum 11.

[0019] The balance weight 15 is fixed to the hoisting machine main body 2 by a plurality of weight bolts 19. The center of gravity of the assembly formed by attaching the installation auxiliary device to the elevator hoisting machine 1 is adjusted by the balance weight 15. The balance weight 15 also serves as a lifting rope stopper. The lifting rope stopper prevents the lifting rope 12 from coming off the rope drum 11.

[0020] Next, we will explain the installation method of the elevator hoisting machine 1. Figure 3 is a configuration diagram showing a first example of the installation method of the elevator hoisting machine 1 of Figure 1. The elevator shown in Figure 3 is a machine room-less elevator, and the elevator hoisting machine 1 is installed at the top of the hoistway 21.

[0021] A first lifting beam 22 and a second lifting beam 23 are installed at the top of the hoistway 21. When viewed from directly above, the second lifting beam 23 is closer to the landing than the first lifting beam 22. A first lifting hook may be used instead of the first lifting beam 22, and a second lifting hook may be used instead of the second lifting beam 23.

[0022] Installed within hoistway 21 are a first car guide rail 24, a second car guide rail (not shown), a first counterweight guide rail 25, and a second counterweight guide rail 26. The first car guide rail 24 and the second car guide rail guide the car as it moves up and down. The first counterweight guide rail 25 and the second counterweight guide rail 26 guide the counterweight as it moves up and down.

[0023] A support beam 27 is installed at the top of the elevator shaft 21. The support beam 27 is disposed below the first lifting beam 22. The support beam 27 is supported by the first car guide rail 24, the first counterweight guide rail 25, and the second counterweight guide rail 26.

[0024] A control panel 28 is installed in the elevator shaft 21. In the first embodiment, the control panel 28 is placed at a position higher than the floor of the top floor landing. The control panel 28 controls the elevator hoisting machine 1, thereby controlling the operation of the car. Power is supplied to the control panel 28 via a power cable 29.

[0025] The elevator hoist 1 is placed at the lowest floor landing. The installation auxiliary device shown in Figure 2 is attached to the elevator hoist 1. The lifting rope 12 is pulled out from the rope drum 11. The tip of the lifting rope 12 is connected to the first lifting beam 22 using the connector 13. In other words, the tip of the lifting rope 12 is connected to the building.

[0026] A temporary cable 16 is connected between the control panel 28 and the elevator hoisting machine 1. Electric power is supplied to the hoisting machine motor 6 from the control panel 28 via the temporary cable 16.

[0027] When installing the elevator machine 1, a worker carries the elevator machine 1 into the lowest floor landing. The installation auxiliary device may be attached to the elevator machine 1 in advance before shipping from the factory, or may be attached to the elevator machine 1 at the installation site.

[0028] After the elevator hoisting machine 1 is delivered, the worker pulls out the lifting rope 12 from the rope drum 11 and connects the tip of the lifting rope 12 to the first lifting beam 22. The worker also connects the temporary cable 16 between the control panel 28 and the elevator hoisting machine 1.

[0029] From this state, the worker rotates the drive sheave 3 and the rope drum 11 using the hoisting machine motor 6, causing the rope drum 11 to reel in the lifting rope 12. As a result, the elevator hoisting machine 1 moves upwards within the hoistway 21, as shown in FIG.

[0030] When the elevator hoisting machine 1 moves above the support beam 27, the worker installs the elevator hoisting machine 1 on the support beam 27, as shown in Figure 5. After this, the worker removes the installation auxiliary device and temporary cable 16, and connects a permanent motor cable between the control panel 28 and the elevator hoisting machine 1. The permanent motor cable is a cable that will be used after the elevator is installed.

[0031] Fig. 6 is a configuration diagram showing a second example of the method for installing the elevator hoisting machine 1 of Fig. 1. In the second example, a worker carries the elevator hoisting machine 1 into the top floor landing.

[0032] After the elevator hoisting machine 1 is delivered, the worker pulls out the lifting rope 12 from the rope drum 11 and connects the tip of the lifting rope 12 to the first lifting beam 22. The worker also connects the permanent motor cable 30 between the control panel 28 and the elevator hoisting machine 1.

[0033] In addition, the worker connects the manual chain block 31 between the second lifting beam 23 and the elevator hoisting machine 1.

[0034] From this state, as shown in Figure 7, the worker uses the hoisting machine motor 6 to wind the lifting rope 12 onto the rope drum 11, while lifting the elevator hoisting machine 1 with the manual chain block 31, and moves the elevator hoisting machine 1 to directly below the second lifting beam 23. As a result, the angle of the lifting rope 12 with respect to the vertical direction becomes smaller than when the elevator hoisting machine 1 was placed at the top floor landing.

[0035] After this, the worker removes the manual chain block 31 and causes the hoisting machine motor 6 to wind the lifting rope 12 onto the rope drum 11. As a result, the elevator hoisting machine 1 moves upward in the hoistway 21 by itself, as shown in FIG.

[0036] When the elevator hoisting machine 1 moves above the support beam 27, the worker installs the elevator hoisting machine 1 on the support beam 27, as shown in Figure 9. After this, the worker removes the installation auxiliary device. In the second example, the permanent motor cable 30 can be left as it is.

[0037] The method for installing the elevator hoisting machine 1 according to the first embodiment includes a carrying-in step, a drum fixing step, a lifting rope connecting step, a moving step, and an installation step.

[0038] The carrying-in process is a process of carrying the elevator hoisting machine 1 and the installation auxiliary device into the landing. The drum fixing process is a process of fixing the rope drum 11 to the drive sheave 3. The lifting rope connecting process is a process of connecting the lifting rope 12 to the building.

[0039] The moving process is a process in which the drive sheave 3 and the rope drum 11 are rotated by the hoisting machine motor 6, and the elevator hoisting machine 1 is moved to the installation height while the lifting rope 12 is wound onto the rope drum 11. The installation process is a process in which the elevator hoisting machine 1 is installed on the support beam 27.

[0040] Next, a detailed description will be given of a method for attaching the installation auxiliary device to the elevator hoisting machine 1. Fig. 10 is an exploded front view showing the elevator hoisting machine 1 of Fig. 1 with the suspension body anti-detachment device 4, a pair of eyebolts 5, and multiple sheave fixing bolts 8 removed. In Fig. 10, the multiple sheave fixing bolts 8 are not shown.

[0041] A rotor of the hoist motor 6 is provided with a plurality of first screw holes 2a. A corresponding sheave fixing bolt 8 is screwed into each of the first screw holes 2a. A plurality of sheave holes 3a are provided in the drive sheave 3. A corresponding sheave fixing bolt 8 is passed through each of the sheave holes 3a.

[0042] A pair of second screw holes 2b are provided on the upper surface of the hoisting machine body 2. A corresponding eyebolt 5 is screwed into each of the second screw holes 2b.

[0043] A plurality of third screw holes 2c are provided on the front surface of the hoisting machine body 2. A corresponding anti-detachment fixing bolt 9 is screwed into each of the third screw holes 2c.

[0044] Fig. 11 is an exploded front view showing a method for attaching the rope drum 11 to the elevator hoisting machine 1 of Fig. 10. Fig. 12 is an exploded side view showing a method for attaching the rope drum 11 to the elevator hoisting machine 1 of Fig. 10.

[0045] Fig. 13 is a front view showing a state in which the rope drum 11 of Fig. 11 is fixed to the drive sheave 3. Fig. 14 is a side view showing a state in which the rope drum 11 of Fig. 12 is fixed to the drive sheave 3.

[0046] A plurality of drum holes 11a are provided in the rope drum 11. When the rope drum 11 is fixed to the drive sheave 3, each drum hole 11a is overlapped with a corresponding sheave hole 3a and a corresponding first screw hole 2a.

[0047] The rope drum 11 is fixed to the drive sheave 3 by a plurality of drum fixing bolts 17. Note that the sheave fixing bolts 8 may be used as each drum fixing bolt 17.

[0048] Each drum fixing bolt 17 is passed through the corresponding drum hole 11a and the corresponding sheave hole 3a and screwed into the corresponding first screw hole 2a. That is, the rope drum 11 and the drive sheave 3 are fastened together to the rotor of the hoist motor 6 by the multiple drum fixing bolts 17 using the multiple drum holes 11a, the multiple sheave holes 3a, and the multiple first screw holes 2a.

[0049] Fig. 15 is an exploded plan view showing a method for attaching guide member 14 to elevator hoisting machine 1 of Fig. 13. Fig. 16 is an exploded front view showing a method for attaching guide member 14 to elevator hoisting machine 1 of Fig. 13.

[0050] Fig. 17 is a plan view showing a state in which the guide member 14 of Fig. 15 is fixed to the hoist body 2. Fig. 18 is a front view showing a state in which the guide member 14 of Fig. 16 is fixed to the hoist body 2.

[0051] A pair of guide member holes 14a are provided in the guide member 14. When the guide member 14 is fixed to the hoisting machine main body 2, each guide member hole 14a is overlapped with a corresponding second screw hole 2b.

[0052] Each guide member bolt 18 is passed through a corresponding guide member hole 14a and screwed into a corresponding second screw hole 2b. That is, the guide member 14 is attached to the hoisting machine main body 2 by a pair of guide member bolts 18, utilizing a pair of guide member holes 14a and a pair of second screw holes 2b.

[0053] FIG. 19 is an exploded front view showing a method for attaching balance weight 15 to elevator hoisting machine 1 of FIG.

[0054] The balance weight 15 has a plurality of weight holes 15a. Since the balance weight 15 also serves as a lifting rope stopper, each weight hole 15a also serves as a stopper hole. When the balance weight 15 is fixed to the hoisting machine main body 2, each weight hole is overlapped with the corresponding third screw hole 2c.

[0055] 2 is passed through the corresponding weight hole 15a and screwed into the corresponding third screw hole 2c. That is, the balance weight 15 is attached to the elevator hoisting machine 1 by the multiple weight bolts 19 using the multiple weight holes 15a and the multiple third screw holes 2c.

[0056] Note that the locking bolts 9 may be used as the weight bolts 19.

[0057] In such an installation auxiliary device and installation method for an elevator hoist 1, the hoist motor 6 rotates the drive sheave 3 and the rope drum 11, the lifting rope 12 is wound onto the rope drum 11, and the elevator hoist 1 moves to the installation height.

[0058] For this reason, when the elevator hoisting machine 1 has been moved to the installation height, no chain block is interposed between the first lifting beam 22 and the elevator hoisting machine 1. Therefore, the elevator hoisting machine 1 can be brought closer to the first lifting beam 22, and the elevator hoisting machine 1 can be installed at a higher position within the hoistway 21.

[0059] As a result, when the elevator hoisting machine 1 is placed directly above the ascent and descent stroke of the counterweight, the ascent and descent stroke of the counterweight can be lengthened for the same height of the hoistway.

[0060] Furthermore, it is possible to omit a chain block or reduce the number of chain blocks used, which reduces the effort required to install and remove the chain block and facilitates the installation of the elevator hoisting machine 1. It also reduces the number of work steps in the overall elevator installation work.

[0061] Furthermore, since the elevator hoist 1 can be moved by the driving force of the hoist motor 6, the burden on the worker can be reduced compared to when operating a chain block manually.

[0062] Furthermore, the rope drum 11 and the drive sheave 3 are fastened together to the rotor of the hoist motor 6 by a plurality of drum fixing bolts 17, using a plurality of drum holes 11a, a plurality of sheave holes 3a, and a plurality of first screw holes 2a. Therefore, the rope drum 11 can be easily attached to an existing type of elevator hoist 1, and the rope drum 11 and the drive sheave 3 can be rotated integrally.

[0063] In addition, a guide member 14 is attached to the hoisting machine body 2. This allows the lifting rope 12 to be stably wound onto the rope drum 11. In addition, the lifting rope 12 can be stably unwound from the rope drum 11.

[0064] Furthermore, the guide member 14 is attached to the hoisting machine main body 2 by utilizing the pair of guide member holes 14a and the pair of second screw holes 2b. Therefore, the guide member 14 can be easily attached to an existing type of elevator hoisting machine 1.

[0065] In addition, a balance weight 15 is attached to the hoisting machine main body 2. This allows the elevator hoisting machine 1 to move in a stable posture.

[0066] Furthermore, balance weight 15 is attached to elevator hoisting machine 1 using multiple weight holes 15a and multiple third screw holes 2c. Therefore, balance weight 15 can be easily attached to existing types of elevator hoisting machine 1.

[0067] The balance weight 15 also serves as a lifting rope stopper, which can more reliably prevent the lifting rope 12 from coming off the rope drum 11. It can also prevent an increase in the number of parts.

[0068] The balance weight and the lifting rope stopper may be separate members.

[0069] In addition, at least one of the balance weight and the lifting rope stopper may be omitted.

[0070] Moreover, the guide member 14 may be omitted.

[0071] Furthermore, in the first embodiment, when the elevator hoisting machine 1 is installed, power is supplied to the elevator hoisting machine 1 from the control panel 28. However, power may be supplied to the elevator hoisting machine 1 from a control device, a portable battery, or the like, separate from the control panel 28.

[0072] Although the preferred embodiments have been described in detail above, the present invention is not limited to the above-described embodiments, and various modifications and substitutions can be made to the above-described embodiments without departing from the scope of the claims.
