FIG. 1 is a schematic perspective view of an elevator apparatus according to an embodiment of the present invention, and FIG. 2 is an enlarged perspective view of the elevator apparatus portion of FIG. As shown in FIG.1 and FIG.2, the riding rod 4 raises / lowers along a pair of riding guide rails 2a, 2b provided in the hoistway. C / W guide rails 1a and 1b are provided on the back side of the riding rod 4, and the C / W 3 is moved up and down along the C / W guide rails 1a and 1b. The riding rod 4 and the C / W 3 are suspended from both ends of the rope 5 wound around the sheave of the thin hoisting machine 11, and conflict with each other via the rope 5 by rotationally driving the thin hoisting machine 11. Go up and down in the direction. A drive system including the thin hoisting machine 11 is incorporated in the tower unit 30. The tower unit 30 includes a support structure 20 provided immediately above the C / W guide rails 1a and 1b.
[0014]
The support structure 20 is configured so that the flat and thin hoisting machine 11, the first sheave 12, and the second sheave 13 do not interfere with the hoisting / trajectory of the riding rod 4 so as not to interfere with the hoisting / lowering trajectory of the riding rod 4, respectively. It supports so that it may be arranged between walls.
[0015]
In this case, the support structure 20 includes bracket members 21a and 21b attached above the C / W guide rails 1a and 1b, a two-stage transverse beam 22 passed over the bracket members 21a and 21b, and a two-stage transverse beam. 22 is provided with vertical frame members 23a and 23b provided in the extending direction of the C / W guide rails 1a and 1b, and an upper beam 24 which is provided approximately horizontally on the upper surfaces of the vertical frame members 23a and 23b. Yes.
[0016]
A substantially horizontal beam 25 is passed between the upper beam 24 and a bracket 2k provided on one riding guide rail 2a. The other riding guide rail 2b is provided at a position substantially symmetrical to the riding guide rail 2a with respect to the movement track of the riding rod 4.
[0017]
The thin hoisting machine 11 of this embodiment is arranged so that the vertical axis, that is, the rotation axis is horizontal, and the upper and lower parts of the thin hoisting machine 11 are the upper beam 24 and the two-stage horizontal beam 22 respectively. Is supported by the upper beam 22u.
[0018]
The first sheave 12 is supported by a sheave bracket 26 fixed between the upper beam 22u and the lower beam 22d of the two-stage horizontal beam 22 so that the rotation axis is horizontal, that is, the horizontal axis. .
[0019]
As shown in FIG. 2, the upper beam 22u and the lower beam 22d of the two-stage horizontal beam 22 form a hollow portion that rotatably accommodates the first sheave 12 and allows passage of the rope 5 described later. It is comprised by C-type beam material. Therefore, the first sheave 12 can be easily replaced by removing the sheave bracket 26.
[0020]
In this case, the first sheave 12 and the thin hoisting machine 11 are arranged in substantially the same plane. Furthermore, the surface of the first sheave 12 on the second riding rod guide rail 2b side is located almost immediately below the surface of the hoisting machine 11 on the beam 25 side (first riding rod guide rail 2a side). .
[0021]
The second sheave 13 is supported by a sheave bracket 27 fixed to the beam 25 so that the vertical direction, that is, the rotation axis is horizontal. The circumferential surface on the depth side (C / W side) of the second sheave 13 is located almost immediately above the circumferential surface on the beam 25 side of the first sheave 12. In this case, a vertical frame member 23a is arranged substantially immediately above the peripheral surface of the first sheave on the beam 25 side. The vertical frame member 23a accommodates the depth side peripheral surface portion of the second sheave 13 and will be described later. In order to allow the rope 5 to pass, it is made of a C-shaped beam material. Further, the first sheave 12 and the second sheave 13 are orthogonal to each other.
[0022]
The vertical frame member 23a may be a hat-type beam material in addition to the C-type beam material. On the other hand, for the vertical frame member 23b, a form that can be easily attached from the hoistway wall surface, for example, H-shaped steel or the like is used.
[0023]
In addition, a rope hitch 28 for fixing one end of the rope 5 on the side where the C / W 3 is suspended is provided between the upper beam 22u and the lower beam 22d of the lower part of the thin hoisting machine 11.
[0024]
Moreover, C / W3 provided so that raising / lowering is possible along C / W guide rail 1a, 1b has C / W sheave 3a in the upper center part.
[0025]
On the other hand, bottom sheaves 4 a and 4 b are provided on the lower side of the bottom surface portion of the riding rod 4. A straight line connecting both bottom sheaves 4 a and 4 b passes directly under the center of gravity of the riding rod 4.
[0026]
In addition, a rope hitch 2h for fixing one end of the rope 5 on the side where the riding rod 4 is suspended is provided at a position substantially the same height as the thin hoist 11 on the riding guide rail 2b.
[0027]
When such a tower unit 30 is adopted, the rope 5 for raising / lowering control of the riding rod 4 and the C / W 3 is connected from the rope hitch 28 to the C / W sheave 3a, the hoisting machine 11, and the first sheave. The second sheave 13 is twisted by 12 and 90 degrees, and is further twisted and passed to the rope hitch 2 h via the bottom sheaves 4 a and 4 b of the riding rod 4.
[0028]
Next, the operation of the present embodiment will be described.
[0029]
When the thin hoist 11 operates, the rope 5 is wound up in a predetermined direction. For example, when the rope 5 moves in the A direction shown in FIG. 2, the riding rod 2 rises and the C / W 3 falls, and when the rope 5 moves in the B direction, the riding rod 2 descends and the C / W 3 becomes To rise. Since the straight line connecting the bottom sheaves 4a and 4b passes directly under the center of gravity of the riding rod 4, so-called suspension of the center of gravity of the riding rod 4 is realized, and the riding rod 4 can stably move up and down.
[0030]
According to the present embodiment, the support structure 20 that supports the thin hoisting machine 11, the first sheave 12 and the second sheave 13 is supported by the C / W guide rails 1a and 1b. The rope 5 for raising / lowering control of the riding rod 4 and C / W3 can be smoothly guided without imposing a load on construction.
[0031]
Further, the length of the rope 5 can also be suppressed to the minimum necessary, and no countermeasures against the swing of the rope 5 are required.
[0032]
Furthermore, since this embodiment is a 2: 1 roping type, the capacity of the thin hoisting machine 11 is small, and the thin hoisting machine 11 does not press the hoistway space.
[0033]
Moreover, since the rope hitch 28 is provided below the hoisting machine 11, the arrangement balance of the rope 5 via the C / W sheave 3a is excellent, and the width of the C / W 3 can be used effectively. . However, the rope hitch 28 can be supported by the C / W guide rail 1b.
[0034]
When assembling the elevator apparatus as shown in FIGS. 1 and 2, first, the thin hoisting machine 11, the first sheave 12 and the second sheave 13 are supported by the support structure 20, and the tower unit 30 is assembled. After that, the tower unit 30 is attached to the upper ends of the C / W guide rails 1a and 1b. In this case, it is preferable to attach it directly above the C / W guide rails 1a and 1b. In this way, the construction of the thin hoist 11, the first sheave 12, and the second sheave 13 in the hoistway can be carried out very efficiently.
[0035]
However, it is also possible to construct the support structure 20 and the hoisting machine 11 and the like sequentially at the upper ends of the C / W guide rails 1a and 1b. An example of such a construction method will be described.
[0036]
First, bracket members 21a and 21b are attached to the tops of the C / W guide rails 1a and 1b. Then, the two-stage horizontal beam 22 incorporating the first sheave 12 and the rope hitch 28 is placed on the bracket members 21a and 21b.
[0037]
Thereafter, the vertical frame members 23a and 23b and the thin hoisting machine 11 are installed on the two-stage horizontal beam 22, the upper beam 24 is passed, and the vertical frame members 23a and 23b and the thin hoisting machine 11 are fixed.
[0038]
Subsequently, the bracket 2k is attached to the upper part of the riding guide rail 2a, and the beam 25 is passed. The second sheave 13 is supported by the sheave bracket 27.
[0039]
【The invention's effect】
According to the present invention, since the supporting structure for supporting the thin hoisting machine, the first sheave and the second sheave is supported by the C / W guide rail, it can be configured without imposing load on the construction work such as the hoistway. It is possible to smoothly guide the rope for climbing control of the riding rod and C / W.
[0040]
In addition, according to the present invention, after assembling the tower unit by incorporating a thin hoisting machine or the like, the tower unit is attached to the upper end of the C / W guide rail. The construction of one sheave and second sheave can be performed very efficiently.
