Hereinafter, embodiments will be described with reference to the drawings.
Embodiment 1.
FIG. 1 is a front view showing an elevator hoisting machine according to a first embodiment. In the figure, an elevator hoist 1 includes a hoist main body 2, a drive sheave 3, a suspension retainer 4, and a pair of eye bolts 5.

The hoist main body 2 includes a hoist motor 6 and a pair of hoist brakes 7. The hoist motor 6 rotates the drive sheave 3. A pair of hoisting machine brakes 7 maintain the drive sheave 3 in a stationary state. Furthermore, the pair of hoist brakes 7 brake the rotation of the drive sheave 3.

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 a 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.

The suspension retainer 4 is fixed to the front surface of the hoist main body 2 by a plurality of retainer fixing bolts 9. The suspension stopper 4 prevents the suspension from coming off the drive sheave 3.

A pair of eye bolts 5 are attached to the upper part of the hoist main body 2. For example, when transporting the elevator hoisting machine 1, the elevator hoisting machine 1 is lifted using a pair of eye bolts 5.

FIG. 2 is a front view showing a state in which the installation assistance device according to the first embodiment is attached to the elevator hoisting machine 1 of FIG. 1.

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

The rope drum 11 is fixed to the drive sheave 3. Further, the rope drum 11 is rotated integrally with the drive sheave 3 by the hoist motor 6 around the rotation center of the drive sheave 3. 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.

The lifting rope 12 is wound around the rope drum 11 as the rope drum 11 rotates. In FIG. 2, most of the lifting rope 12 is wound around 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.

The guide member 14 is fixed to the hoist main body 2 by a plurality of guide member bolts 18. Further, the guiding member 14 guides the lifting rope 12 to the rope drum 11 when the lifting rope 12 is wound around the rope drum 11. Further, the guiding member 14 guides the lifting rope 12 to the draw-out opening when pulling out the lifting rope 12 from the rope drum 11.

The balance weight 15 is fixed to the hoist 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 hoist 1 is adjusted by a balance weight 15. Further, the balance weight 15 also serves to prevent the lifting rope from coming off. The lifting rope detachment prevents the lifting rope 12 from coming off from the rope drum 11.

Next, a method for installing the elevator hoist 1 will be explained. FIG. 3 is a configuration diagram showing a first example of an installation method for the elevator hoisting machine 1 of FIG. 1. As shown in FIG. The elevator shown in FIG. 3 is a machine room-less elevator, and the elevator hoist 1 is installed at the top of the hoistway 21.

At the top of the hoistway 21, a first lifting beam 22 and a second lifting beam 23 are installed. 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.

Inside the hoistway 21, 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 are installed. The first car guide rail 24 and the second car guide rail guide the raising and lowering of the car. The first counterweight guide rail 25 and the second counterweight guide rail 26 guide the lifting and lowering of the counterweight.

A support beam 27 is installed at the top of the hoistway 21. The support beam 27 is arranged below the first lifting beam 22 . Further, the support beam 27 is supported by a first car guide rail 24, a first counterweight guide rail 25, and a second counterweight guide rail 26.

A control panel 28 is installed within the hoistway 21. The control panel 28 in the first embodiment is arranged at a position higher than the floor of the top floor landing. Further, the control panel 28 controls the operation of the car by controlling the elevator hoist 1. Electric power is supplied to the control panel 28 via a power cable 29.

The elevator hoist 1 is placed at the bottom floor landing. Further, the elevator hoisting machine 1 is equipped with an installation assistance device shown in FIG. 2 . 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 a connector 13. That is, the tip of the lifting rope 12 is connected to the building.

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

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

After carrying in the elevator hoist 1, the operator 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 hoist 1.

From this state, the operator rotates the drive sheave 3 and the rope drum 11 using the hoist motor 6, and causes the rope drum 11 to wind the lifting rope 12. Thereby, the elevator hoisting machine 1 moves upward in the hoistway 21, as shown in FIG.

When the elevator hoist 1 moves above the support beam 27, the operator installs the elevator hoist 1 on the support beam 27, as shown in FIG. Thereafter, the operator removes the installation auxiliary device and the temporary cable 16, and connects the permanent motor cable between the control panel 28 and the elevator hoist 1. The main motor cable is a cable that is used after the elevator is installed.

FIG. 6 is a configuration diagram showing a second example of the method for installing the elevator hoist 1 of FIG. 1. In the second example, the worker carries the elevator hoist 1 into the top floor landing.

After carrying in the elevator hoist 1, the operator 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 operator also connects the main motor cable 30 between the control panel 28 and the elevator hoist 1.

Furthermore, the operator connects the manual chain hoist 31 between the second lifting beam 23 and the elevator hoist 1.

From this state, as shown in FIG. 7, the operator lifts the elevator hoist 1 using the manual chain hoist 31 while winding the lifting rope 12 around the rope drum 11 using the hoist motor 6, and lifts the elevator hoist 1. The upper machine 1 is moved directly below the second lifting beam 23. Thereby, the angle of the lifting rope 12 with respect to the vertical direction becomes smaller than when the elevator hoist 1 is placed at the top floor landing.

Thereafter, the operator removes the manual chain block 31 and causes the hoist motor 6 to wind the lifting rope 12 around the rope drum 11. Thereby, the elevator hoisting machine 1 moves upward in the hoistway 21, as shown in FIG.

When the elevator hoist 1 moves above the support beam 27, the operator installs the elevator hoist 1 on the support beam 27, as shown in FIG. After this, the worker removes the installation aid. In the second example, the main motor cable 30 can be left as is.

The method for installing the elevator hoist 1 according to the first embodiment includes a carrying-in process, a drum fixing process, a lifting rope connecting process, a moving process, and an installation process.

The carrying-in process is a process of carrying the elevator hoist 1 and the installation auxiliary device into the hall. The drum fixing process is a process of fixing the rope drum 11 to the drive sheave 3. The lifting rope connection process is a process of connecting the lifting rope 12 to the building.

The moving process is a process in which the drive sheave 3 and the rope drum 11 are rotated by the hoist motor 6, and the elevator hoist 1 is moved to the installation height while winding the lifting rope 12 around the rope drum 11. The installation process is a process of installing the elevator hoist 1 on the support beam 27.

Next, a detailed method for attaching the installation assistance device to the elevator hoisting machine 1 will be described.

The rope drum 11 is provided with a plurality of drum holes 11a. When fixing the rope drum 11 to the drive sheave 3, each drum hole 11a is overlapped with the corresponding sheave hole 3a and the corresponding first screw hole 2a.

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

Each drum fixing bolt 17 is passed through the corresponding drum hole 11a and the corresponding sheave hole 3a, and is screwed into the corresponding first screw hole 2a. That is, the rope drum 11 and the drive sheave 3 are connected to the hoisting machine motor 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. It is fastened together with the rotor No. 6.

FIG. 15 is an exploded plan view showing a method of attaching the guide member 14 to the elevator hoist 1 of FIG. 13. FIG. 16 is an exploded front view showing a method of attaching the guide member 14 to the elevator hoisting machine 1 shown in FIG. 13.

The guide member 14 is provided with a pair of guide member holes 14a. Each guide member hole 14a is overlapped with the corresponding second screw hole 2b when fixing the guide member 14 to the hoisting machine main body 2.

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

FIG. 19 is an exploded front view showing a method of attaching the balance weight 15 to the elevator hoisting machine 1 of FIG. 18.

The balance weight 15 is provided with a plurality of weight holes 15a. Since the balance weight 15 also serves as a stopper for the lifting rope, each weight hole 15a also serves as a stopper hole. Each weight hole is overlapped with the corresponding third screw hole 2c when fixing the balance weight 15 to the hoisting machine main body 2.

Each weight bolt 19 shown in FIG. 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 hoist 1 with a plurality of weight bolts 19 using a plurality of weight holes 15a and a plurality of third screw holes 2c.

Note that the locking bolt 9 may be used as each weight bolt 19.

In such an installation auxiliary device and installation method for the elevator hoisting machine 1, the hoisting machine motor 6 rotates the drive sheave 3 and the rope drum 11, and the lifting rope 12 is wound around the rope drum 11. The hoist 1 moves to the installation height.

Therefore, when the elevator hoist 1 is moved to the installation height, no chain block is interposed between the first lifting beam 22 and the elevator hoist 1. Therefore, the elevator hoist 1 can be brought closer to the first lifting beam 22, and the elevator hoist 1 can be installed at a higher position in the hoistway 21.

Thereby, when the elevator hoist 1 is disposed directly above the lifting stroke of the counterweight, the lifting stroke of the counterweight can be made longer for the same height of the hoistway.

Furthermore, chain blocks can be omitted or the number of chain blocks used can be reduced. Thereby, the effort of installing and removing the chain block can be reduced, and the elevator hoist 1 can be installed easily. Further, the number of work steps in the entire elevator installation work can be reduced.

Furthermore, since the elevator hoist 1 can be moved by the driving force of the hoist motor 6, the burden on the operator can be reduced compared to when the chain hoist is manually operated.

Further, the rope drum 11 and the drive sheave 3 are connected to the hoisting machine motor 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. It is fastened together with the rotor No. 6. Therefore, the rope drum 11 can be easily attached to the existing type of elevator hoisting machine 1, and the rope drum 11 and the drive sheave 3 can be rotated together.

Further, a guide member 14 is attached to the hoist main body 2. Therefore, the lifting rope 12 can be stably wound around the rope drum 11. Further, the lifting rope 12 can be stably pulled out from the rope drum 11.

Further, the guide member 14 is attached to the hoist main body 2 using a pair of guide member holes 14a and a pair of second screw holes 2b. Therefore, the guide member 14 can be easily attached to the existing type of elevator hoisting machine 1.

Further, a balance weight 15 is attached to the hoist main body 2. Therefore, the elevator hoist 1 can be moved in a stable posture.

Further, the balance weight 15 is attached to the elevator hoist 1 using the plurality of weight holes 15a and the plurality of third screw holes 2c. Therefore, the balance weight 15 can be easily attached to the existing type of elevator hoisting machine 1.

Further, the balance weight 15 also serves to prevent the lifting rope from coming off. Therefore, it is possible to more reliably prevent the lifting rope 12 from coming off from the rope drum 11. Further, an increase in the number of parts can be suppressed.

Note that the balance weight and the lifting rope retainer may be separate members.

Furthermore, at least one of the balance weight and the lifting rope stopper may be omitted.

Further, the guide member 14 may be omitted.

Further, in the first embodiment, power is supplied to the elevator hoisting machine 1 from the control panel 28 when the elevator hoisting machine 1 is installed. However, power may be supplied to the elevator hoist 1 from a control device other than the control panel 28, a portable battery, or the like.

Although the preferred embodiments have been described in detail above, they are not limited to the embodiments described above, and various modifications may be made to the embodiments described above without departing from the scope of the claims. Variations and substitutions can be made.
