Description

  The present invention relates to an elevator apparatus, and more particularly to a machine room-less elevator hoisting machine support structure in which a hoisting machine is installed using a space in a hoistway.

  In recent years, in order to increase the efficiency of use of buildings, elevators that install hoisting machines and control panels using the space in the hoistway, so-called machine room-less elevators, are used to raise and lower the hoistway. A counterweight that moves in the opposite direction, a guide rail that guides the raising and lowering of the car and the counterweight, a rope that suspends the car and the counterweight, and is located near the floor level at the lowest floor of the hoistway in the hoistway, and A structure composed of a thin hoisting machine arranged in parallel with one wall surface in the plane cross section of the hoistway has been proposed and partially put into practical use. And as a support of the hoisting machine described above, the hoisting machine base is suspended by a mechanical base via a rubber vibration isolator and the hoisting machine is fixed to the hoisting machine base (for example, see Patent Document 1), or There is one in which a fixing base for fixing the hoisting machine is fixed to an assembly guide rail so as to be movable in a square shape (for example, see Patent Document 2).

JP-A-2005-231770 (paragraph number 0013, FIG. 3) JP 2006-52076 (paragraph number 0013, FIG. 2)

  However, in the thing of the cited reference 1, since it has the structure which fixes a hoisting machine after mounting a hoisting machine on the suspended fixing stand, you must pass a suspension member on the outer side of a hoisting machine. In addition to the hoisting machine width, the width of the suspension member is required, and the hoistway dimension is increased.

  On the other hand, in the one described in the cited document 2, the fixing base is assembled in a square shape with the upper frame, the lower frame and the side frame, and one end of each of the upper frame and the lower frame is movably fixed to the guide rail, And although it is the structure which fixed the lower frame to the pit base with the tension rod, arrangement of the side frame with respect to the hoisting machine is not particularly limited, and when the side frame is arranged outside the hoisting machine, the patent document As with 1, the width of the side frame is required in addition to the hoisting machine width. Further, no special consideration has been given to reduce the thickness dimension of the fixed base, and therefore there has been a problem that the hoistway dimension is enlarged.

  The present invention has been made from the above-described prior art, and an object of the present invention is to provide an elevator apparatus capable of preventing the hoistway dimensions from being enlarged without significantly changing the components.

  In order to achieve the above object, the invention according to claim 1 of the present invention includes a car and a counterweight that move up and down in a hoistway, a guide rail that guides the raising and lowering of the car and the counterweight, the car and the A rope for suspending a counterweight, and a thin winding in the hoistway that is near the floor level at the lowest floor of the hoistway and that is disposed substantially parallel to one wall surface in the plane section of the hoistway In an elevator having an upper machine and a mounting frame that supports the hoisting machine, the mounting frame is assembled in a cross beam shape with an upper frame, a lower frame, and a side frame, and the side frame is located on the inner side of the hoisting machine width. It is characterized by having been arranged in.

  In the invention according to claim 1 of the present invention configured as described above, the mounting frame that supports the hoisting machine is assembled in a cross-girder shape with the upper frame, the lower frame, and the side frame, and the side frame is located inside the hoisting machine width. The mounting frame can be made smaller in width than the hoisting machine so that the hoistway dimensions can be prevented from expanding without significantly changing the components. it can.

  In the invention according to claim 2 of the present invention, the side frame has a substantially L-shaped cross-sectional shape, and one side of the side frame is disposed between the hoisting machine fixing portion and the sheave. It is a feature.

  In the invention according to the first aspect of the present invention configured as described above, by making the cross-sectional shape of the side frame substantially L-shaped, one side of the L-shaped side frame is secured while ensuring the strength as the side frame. By arranging between the winding machine fixing part and the sheave, the side frame can be accommodated within the thickness dimension of the winding machine.

  According to the present invention, by arranging the side frame inside the hoisting machine width, the width dimension of the mounting frame can be made smaller than the width dimension of the hoisting machine, and the L-shaped side frame By arranging one side between the hoisting machine fixing part and the sheave, it is possible to make the thickness dimension of the mounting frame including the side frame smaller than the thickness dimension of the hoisting machine. A hoistway device arrangement plan that does not require an increase in road dimensions is possible. Further, since the mounting frame is composed of the upper frame, the lower frame, and the side frame, it does not require a significant change in the components compared to the conventional frame, and therefore does not lead to an increase in cost. .

It is a principal part enlarged front view which shows one Embodiment of the winding machine support apparatus of this invention. It is a side view of the hoisting machine support apparatus in this embodiment. It is a top view of the hoisting machine support apparatus in this embodiment.

  Hereinafter, an embodiment of an elevator apparatus according to the present invention will be described with reference to the drawings.

  As shown in FIG. 1, the machine room-less elevator includes a car 2 that moves up and down in the hoistway 1, a car guide rail 3 that guides the raising and lowering of the car 2, and a counterweight that moves in a direction opposite to the car 2. 4, weight guide rails 5 a and 5 b for guiding the lifting and lowering of the counterweight 4, a suspension beam 6 fixed to the top of the guide rails 3, 5 a and 5 b, and pulleys 7 and 8 attached to the suspension beam 6. A thin hoisting machine 9 provided with a sheave 9 a, a car lower pulley 10 provided below the car 2, and a counterweight 4. The upper pulley 11 of the weight provided at the upper portion of the door and the one end face the guide rail 3 via the rope end fixing device 12a and are fixed to a guide rail (not shown) for guiding the car 2 The other end is fixed to the suspension beam 6 via the rope end fixing device 12b, and its intermediate portion is wound around the car lower pulley 10, the pulley 7, the sheave 9a, the pulley 8, and the weight upper pulley 11, And a rope 13 that moves up and down the car 2 and the counterweight 4 by moving the sheave 9a driven by the machine 9. A is the top floor level and B is the bottom floor level.

  As shown in FIGS. 2 to 4, the hoisting machine support device according to the first embodiment is formed by assembling the upper frame 14 a, the lower frame 14 b, and the side frames 14 c and 14 d into a cross beam shape, and the hoisting machine 9 Is attached to the mounting frame 14, one end is attached to the lower frame 14 b of the mounting frame 14, the other end is attached to the pit base 15 by a fixing nut (not shown), and the hoisting machine fixing portion 17. And an anti-vibration rubber 18 interposed between the hoisting machine 9 and the mounting frame 14 and absorbing the vibration of the hoisting machine 9.

  As shown in FIGS. 2 and 4, the side frames 14 c and 14 d of the mounting frame 14 are arranged on the inner side of the hoisting machine width. Further, the side frames 14c and 14d are formed of a steel material having a substantially L-shaped cross section, and as shown in FIG. 4, one side of the L-shaped side frames 14c and 14d is connected to the hoisting machine fixing portion 17. And the sheave 9a.
