The drive system of the elevator apparatus by this invention is demonstrated using FIG. 3 is a cross-sectional view of a driving device of an elevator apparatus according to Embodiment 1 of the present invention. In Fig. 3, "14" is a sheave with a rope groove to which the rope 13 is wound, "15" is a shaft which becomes a fixed shaft, "16" is a stator, and "17" is a sheave 14 and Connected rotor. The rotor 17 is formed in a substantially cylindrical shape, and the stator 16 is provided in a cylindrical shape on the outer circumference of the rotor 17. Also, "18" is a drive motor mainly composed of the stator 16 and the rotor 17. Therefore, this drive device 7 is a gearless hoisting machine having a rotor 17 and a stator 16 provided on the outer circumference of the rotor 17.

This brake 21 is provided on the opposite side to the sheave 14 in the drive device 7, and can be inspected from the outside by detaching the outer casing 22 from the drive device 7.

Here, the drive apparatus 7 has a larger outer dimension in the radial direction of the drive motor 18 than the outer dimension in the radial direction of the sheave 14. The radial dimension of this drive motor 18 is determined by the size of the cylindrical stator 16. The drive device 7 is a so-called thin hoist that has a smaller outer dimension B in the axial direction of the sheave 14 than an outer dimension A in the radial direction of the sheave 14. In addition, the outline of the external shape of the whole drive device 7 is close to the "凸" shape which has the sheave 14 in the upper part as shown in FIG.

Installation of the drive system of the elevator apparatus by this invention is demonstrated using FIG. 4 is an installation diagram of a driving device of an elevator apparatus according to Embodiment 1 of the present invention. In FIG. 4, the drive unit 8 which supports the drive device 7 supports the 1st H-shaped steel 8a which becomes the stand of the direct drive 7, and the 1st H-shaped steel 8a. It consists of the 2nd H-beams 8b. Here, in the hoistway plan view, the second H-shaped steel 8b is disposed at the upper part of the hoistway 1 in an "L" shape, and one elevator car guide rail 5 and two counterweight guide rails 6 are provided. That is, it is supported by three guide rails in total.

In the elevator device configured as described above, the driving motor 18 of the driving device 7 is applied to the rotor 17 so that the rotating force is applied to the rotor 17, and the sheave 14 connected to the rotor 17 rotates to form a rope. The elevator car 3 and the counterweight 4 are lifted in opposite directions via 13. And in the hoistway plan view, the diameter of the sheave 14 of the drive device 7 is arrange | positioned on the line which connects the 1st forward pulley 9 and the counterweight pulley 11 provided in one side of the lower part of the elevator car 3, and is arranged. It is. Therefore, the drive device 7 opposes the sheave 14 side against the wall of the hoistway 1 at the corner of the hoistway 1 from the rear side with respect to the door 2 of the elevator car 3. The rotating surface of 14 is inclined with respect to the wall of the hoistway 1.

And in the hoistway plan view, at least a part of the drive device 7 is overlapped with the elevator car 3 and the counterweight 4, and the lower surface of the drive device 7 is provided with the elevator car 3 and the counterweight 4. It is disposed above the highest rising position. In addition, the overlap of the drive device 7 and the elevator car 3 may be more than 1/2 of the total area of the drive device 7, and more preferably 2/3 or more. Similarly, the superimposition of the drive device 7, the elevator car 3, and the counterweight 4 may be more than 1/2 of the area of the entire drive device 7, and more preferably 2/3 or more. Thereby, in the hoist plan view, 1/2 or more of the plane area of the drive device 7 can be arrange | positioned in the plane area formed by the elevator car 3 and the counterweight 4, and the cross-sectional area of the hoist path 1 is adjusted. It can utilize effectively, ie, the cross-sectional area of the hoistway 1 can be made small as a result.

In addition, the drive device 7 has a larger outer dimension in the radial direction of the drive motor 18 than an outer dimension in the radial direction of the sheave 14, and the sheave 14 having a smaller outer dimension has a wall side of the hoistway 1. The drive motor 18 with a large external dimension is arrange | positioned so that it may face the elevator car 3 side. Therefore, the drive device 7 can be laid out easily without interfering with the wall of the hoistway 1.

For this reason, the volume of the hoistway 1 can be reduced, and the drive room 7 is installed in the upper part of the hoistway 1, and the machine room provided separately is abbreviate | omitted. The construction cost can be reduced, and furthermore, the construction cost required by the installation space of the elevator apparatus can be reduced.

In addition, since the drive device 7 is a so-called thin hoist that has a smaller outer dimension in the axial direction of the sheave 14 than the outer dimension in the radial direction of the sheave 14, the drive device 7 enters the space on the elevator car 3. The projecting area of the drive device 7 is relatively small. This makes it possible to sufficiently secure the maintenance space of the inspector on the elevator car 3 even when the inspector climbs onto the elevator car 3 to perform maintenance of the drive device 7 or the like. And this maintenance space is partitioned by the railing 3a on the elevator car 3, but in order to raise the highest lift position of the elevator car 3, the railing 3a on the elevator car is driven in a hoistway plan view. It is installed at a position away from the device (7).

Therefore, the smaller the projected area of the drive device 7 into the space on the elevator car 3, the more the area of the area surrounded by the handrail 3a on the elevator car, which is the maintenance space of the inspector, can be sufficiently secured. And since the part which faces the drive device 7 of the handrail 3a on the elevator car is provided inclined with respect to the wall of the hoistway 1 in the hoist plan view, the inspector maintains and maintains the drive device 7. Can be executed more easily.

In addition, in the case of an elevator apparatus for a heavy load, the mechanical external dimension of the drive apparatus 7 also becomes large, and the external dimension, ie diameter, of the drive motor 18 of the drive apparatus 7 which is a gearless hoisting machine becomes large, Since the drive motor 18 is arranged on the elevator car 3 side, since there is no interference with the wall of the hoistway 1, the cross-sectional area of the hoistway and the drive device 7 are increased even if the diameter of the drive motor 18 is increased to some extent. ) Is not affected by the external dimensions. Therefore, since the sheave 14 is arrange | positioned at the wall side of the hoistway 1, and the drive motor 18 at the elevator car 3 side, the freedom degree of the external dimension of the drive apparatus 7 which is a gearless hoisting machine is improved. You can.

Moreover, in the hoist plan view, the diameter of the sheave 14 of the drive device 7 is arrange | positioned on the line which connects the 1st forward pulley 9 and the counterweight pulley 11 provided in the lower side of the elevator car 3 to one side. As a result, it is possible to reduce costs without having to arrange a special deflection pulley. And since the counterweight 4 and the part of the sheave 14 overlap in the hoist plan view, the counterweight pulley 11 is not arrange | positioned inclined with respect to the counterweight 4, and the counterweight pulley 11 is counterweighted. It can be accommodated and arrange | positioned in the width | variety of (4), and it is not necessary to enlarge a lifting path cross section area by the arrangement of the counterweight pulley 11.

Moreover, the drive unit 7 is supported by the drive unit 8, and this drive unit 8 is arrange | positioned at the upper part of the hoistway 1 in an "L" shape in a plan view of a hoistway, Since the guide rail 5 for the elevator car and the two guide rails 6 for balancing weights, that is, three guide rails in total, the load acting on the drive device 7 acts on the structure of the hoistway 1. Without this, the structure of the hoistway 1 can be reduced in weight and construction cost can be reduced. In addition, since the load acting on the drive unit 8 by the drive unit 7 is distributed over three rails, each rail size can be reduced and the manufacturing cost can be reduced.

Moreover, since the brake 20 is arrange | positioned facing the elevator car 3 side, by removing the outer casing 22, maintenance of brakes can be performed immediately at the time of maintenance.

That is, regardless of the external dimensions of the drive device, it is possible to provide an elevator device with a small cross-sectional area of the hoistway, and to lay out the drive device easily without being influenced by the cross-sectional area of the hoistway and the external dimensions of the drive device. An elevator device can be provided.

In the hoist plan view, the diameter of the sheave 14 of the drive device 7 is arranged on the line connecting the first turning pulley 9 and the counterweight pulley 11 provided on one side of the lower part of the elevator car 3. It is. Therefore, in the drive device 7, the rotating surface of the sheave 14 is inclined with respect to the wall of the hoistway 1 from the side surface at which the counterweight 4 of the elevator car 3 is arranged.

It is disposed above the raised position. In addition, although the overlap of the drive device 7 and the elevator car 3 becomes smaller than Example 1, since it is the structure in which one elevator car guide rail 5 is arrange | positioned between the elevator car 3 and the counterweight 4, It is not necessary to increase the cross sectional area of the hoistway.

In addition, the drive device 7 has a larger outer dimension in the radial direction of the drive motor 18 than an outer dimension in the radial direction of the sheave 14, and the sheave 14 having a smaller outer dimension has a wall side of the hoistway 1.

The projecting area of the drive device 7 is relatively small. This makes it possible to sufficiently secure the maintenance space of the inspector on the elevator car 3 even when the inspector climbs onto the elevator car 3 to perform maintenance on the drive device 7 or the like.

In addition, in the case of an elevator apparatus for a heavy load, the mechanical external dimension of the drive apparatus 7 also becomes large, and the external dimension, ie diameter, of the drive motor 18 of the drive apparatus 7 which is a gearless hoisting machine becomes large, Since the drive motor 18 is disposed on the elevator car 3 side, there is no interference with the wall of the hoistway 1, so that the diameter of the hoistway motor 18 and the drive device 7 are increased even if the diameter of the drive motor 18 is increased to some extent.
