Hereinafter, embodiments of the present invention will be described with reference to the drawings.

1 is a schematic perspective view of an elevator apparatus according to an embodiment of the present invention. 2 is an enlarged perspective view of a main part of the elevator apparatus of FIG. As shown in FIG. 1 and FIG. 2, a pair of hoisting guide rails 2a and 2b are provided in a hoistway. The lift 4 is lifted along the pair of lift guide rails 2a and 2b. Counterweight guide rail pairs 1a and 1b are provided on the rear side of the elevator 4, that is, on the rear side of the elevated trajectory of the elevator 4. The counterweight 3 moves up and down along the pair of counterweight guide rails 1a and 1b. The rope 5 is wound around the flat thin hoist 11. The lift 4 is suspended at one end of the rope 5 and the counterweight 3 is suspended at the other end of the rope 5. Therefore, when the thin hoist 11 rotates, the elevating box 4 and the counterweight 3 vertically elevate in the opposite direction through the rope 5. The drive system including the thin hoist 11 is built in the frame unit 30. The frame unit 30 has a supporting structure 20 mounted on upper ends of the pair of counterweight guide rails 1a and 1b.

The support structure 20 is a flat thin hoist 11, a first sheave 12, and a second sheave 13, respectively, without interfering with the elevating trajectory of the elevating (4), and elevating (4) The flat thin hoist 11, the first sheave 12, and the second sheave 13 are supported so as to be arranged between the hoistway and the wall of the hoistway.

In this case, the support structure 20 includes bracket members 21a and 21b mounted on the upper ends of the counterweight guide rails 1a and 1b, respectively; Two stage horizontal beams 22 (22u and 22d) placed on the bracket members 21a and 21b; Vertical members 23a and 23b mounted on the two-stage horizontal beams 22 (22u and 22d) and extending in the same direction as the counterweight guide rails 1a and 1b; It includes a substantially horizontal upper beam 24 mounted on the upper surfaces of both vertical members 23a and 23b.

The substantially horizontal beam 25 connects the upper beam 24 with the bracket 2k mounted on one elevating guide rail 2a. The other elevating guide rail 2b is substantially disposed at a symmetrical position of the one elevating guide rail 2a with respect to the elevating trajectory of the elevating box 4.

The thin hoist 11 of this embodiment is arrange | positioned so that the rotation axis of the thin hoist 11 of a perpendicular direction may be horizontal. The upper part of this thin hoist 11 is fixed to the upper beam 24, and the lower part is fixed to the upper horizontal beam 22u.

The first sieve 12 is vertically supported by a sheave bracket 26 fixed between the upper horizontal beam 22u and the lower horizontal beam 22d so that its axis of rotation is horizontal.

As shown in FIG. 2, the upper horizontal beam 22u and the lower horizontal beam 22d rotatably receive the first sheave 12 and at the same time also form a hollow through which the rope 5 can pass. It consists mainly of two opposing C-shaped beam members. Therefore, by removing the sheave bracket 26, the first sheave 12 can be easily removed.

In this case, the first sheave 12 and the thin hoist 11 are arranged in substantially the same plane. In addition, the peripheral surface of the first sheave 12 on the second elevating guide rail 2b is directly below the peripheral surface of the hoist 11 on the beam 25 side (the first elevating guide rail 2a side). It is arranged substantially.

In addition, the second sheave 13 is supported in the vertical direction by the sheave bracket 27 fixed to the beam 25 so that this rotating shaft is horizontal. The peripheral surface of the second sheave 13 on the counterweight side is disposed substantially just above the peripheral surface of the thin first sheave 12 on the beam 25 side. In this case, the vertical member 23a is disposed substantially above the peripheral surface of the first sheave 12 on the beam 25 side. Thus, the vertical member 23a has two opposing C-shaped beam members so as to form a hollow portion through which the rear end of the second sheave 13 is rotatably received and through which the rope 5 can pass. Consists of In addition, the first sheave 12 and the second sheave 13 are orthogonal to each other.

The vertical member 23a may be formed by a hat beam member instead of a C beam member. On the other hand, the vertical member 23b can be easily formed through the wall of the hoistway. For example, it may be formed by an H-shaped member.

A rope hitch 28 is mounted below the thin hoist 11 and between the upper horizontal beam 22u and the lower horizontal beam 22d to fix the other end of the rope 5 which hangs the counterweight 3. It is.

Moreover, the counterweight 3 which can be raised and lowered along a pair of counterweight guide rails 1a and 1b has the counterweight sheave 3a in the upper center part.

On the other hand, bottom sheaves 4a and 4b are provided at the bottom of the lift box 4. The straight line connecting both bottom sheaves 4a and 4b passes just below the center of gravity of the elevating box 4.

In order to fix the one end of the rope 5 which hangs the elevating box 4, the rope hitch 2h is attached to the part of the elevating guide rail 2b at substantially the same height as the thin hoist 11. However, the rope hitch 2h may be attached to another appropriate part.

In addition, when the frame unit 30 is used, the rope 5 for lifting and lowering the lift 4 and the counterweight 3 respectively is a counterweight sheave 3a and a thin hoist from the rope hitch 28. (11), to the first sheave 12, then to the second sheave 13 twisted 90 degrees, to the bottom sheaves 4a and 4b of the lift 4, and to the rope hitch 2h. .

Next, the operation of this embodiment will be described.

The thin hoist 11 is driven to wind the rope 5 in a predetermined direction. For example, when the rope 5 moves in the direction A shown in FIG. 2, the lifting 4 increases and the counterweight 3 moves downward. When the rope 5 moves in the B direction shown in Fig. 2, the lifting box 4 descends and at the same time the counterweight 3 rises. Here, since the straight line connecting the bottom sheave 4a and the bottom sheave 4b passes just below the center of gravity of the elevating box 4, the center of gravity of the elevating box 4 can be set. Therefore, the lift 4 can ascend and rise stably.

According to the present embodiment, the support structure 20 for supporting the thin hoist 11, the first sheave 12 and the second sheave 13 is supported by the counterweight guide rails 1a and 1b. Therefore, the load does not increase in the building construction which forms a hoistway. In addition, it is possible to smoothly guide the rope (5) to control the lifting and lowering the lift box 4 and the counterweight (3), respectively.

Moreover, since the length of the rope 5 is not long, it is not necessary to provide a countermeasure against the shaking of the rope 5 and the like.

In addition, this embodiment is a 2: 1 roping type. Therefore, the thin hoist 11 has a small capacity and occupies only a small space in the hoistway.

Moreover, since the rope hitch 28 is provided below the hoist 11, the arrangement | positioning balance of the rope 5 through the counterweight sheave 3a is excellent. In addition, the entire width of the counterweight 3 can be effectively used. However, the rope hitch 28 may be supported by the counterweight guide rail 1b.

Here, when assembling the elevator apparatus shown in Figs. 1 and 2, first, the thin hoist 11, the first sheave 12 and the second sheave 13 are supported by the support structure 20 to support the frame unit. Assemble (30). Thereafter, the frame unit 30 is mounted on the upper end portions of the counterweight guide rail pairs 1a and 1b. In this case, it is preferable that the frame unit 30 is directly above the counterweight guide rails 1a and 1b. In this way, the thin hoist 11, the first sheave 12 and the second sheave 13 can be installed very easily and efficiently in the hoistway.

However, the support structure 20, the hoist 11, and the like may be mounted in order on the upper ends of the counterweight guide rails 1a and 1b. This elevator assembly method will be described.

First, the bracket members 21a and 21b are mounted on the top portions of the counterweight guide rail pairs 1a and 1b. Subsequently, a two-stage horizontal beam 22 incorporating the first sheave 12 and the rope hitch 28 is placed on the bracket members 21a and 21b.

Thereafter, the vertical members 23a and 23b and the thin hoist 11 are installed on the two-stage horizontal beam 22. Thereafter, the upper beam 24 is installed to fix the vertical members 23a and 23b and the thin hoist 11.

Next, the bracket 2k is mounted on the elevated guide rail 2a, and the beam 25 is installed. Finally, the second sheave 13 is supported by the sheave bracket 27.

According to the present invention, since the support structure for supporting the thin hoist, the first sheave and the second sheave is supported by the counterweight guide rail, the load does not increase in the construction work forming the hoistway. In addition, it is possible to smoothly guide the rope for lifting control of the lift and the counterweight respectively.

According to the present invention, since the frame unit can be mounted on the upper end of the counterweight guide rail after the frame unit is formed, the thin hoisting machine, the first sheave and the second sheave can be installed very easily in the hoistway. .
