DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator guide rail centering apparatus, and more particularly to an elevator guide rail centering apparatus for centering a counterweight guide rail with reference to a car guide rail.

[0002]

2. Description of the Related Art Conventionally, as described in Japanese Utility Model Laid-Open No. 5-32368, for example, a first jig which engages with a centered car guide rail and a counterweight guide rail are sandwiched. A second jig; and a bracket for connecting the first jig and the second jig to each other, and centering the counterweight guide rail with reference to the car guide rail. Elevator guide rail centering devices have been partially put into practical use. And the second
The jig includes a fixed piece that abuts one side of the counterweight guide rail, a moving piece that abuts the other side of the counterweight guide rail, and a bolt that moves the movable piece in the fixed one direction. Have.

In the conventional guide rail centering device constructed as described above, the moving piece is moved in the direction of the fixed piece by screwing the bolt, that is, the counterweight is moved together with the moving piece. The guide rail for counterweight is moved, and the guide rail for counterweight is held by the moving piece and the fixed piece so as to be centered.

[0004]

In the above-described conventional guide rail centering device, the moving piece is configured to be moved by a bolt, so that a bolt tightening operation in a narrow space is required, and In order to remove the device, the work of loosening the bolt is also required, and there is a problem that the workability is not excellent.

The present invention has been made in view of such a situation in the prior art, and an object of the present invention is to provide an elevator capable of easily holding a guide rail for a counterweight without requiring any special operation. It is to provide a guide rail centering device.

[0006]

In order to achieve this object, the present invention provides a first jig for engaging a centered car guide rail, and a second jig for holding a counterweight guide rail. And a bracket for coupling the first jig and the second jig to each other, and for centering the counterweight guide rail based on the car guide rail. in the guide rail centering device, the second jig comprises a fixed piece abutting a side of the counterweight guide rails, which abut the other side of the mosquito <br/> counter weights guide rail A moving piece, a moving shaft integrally supporting the moving piece, and a rotatable connection to the moving shaft via a first rotating shaft.
An arm, and the arm is rotatable via a second rotation shaft.
Connected and rotatably supported about a third pivot axis.
And a handle for rotating the third rotation shaft.
The arm is rotated in one direction to move the moving shaft through the arm.
And moving the moving piece in the direction of the fixed piece,
And the moving piece and the guide rail for the counterweight
When the moving piece is held by the side, the moving piece
Pull the guide rail for
The first rotation axis, the second rotation axis, and the third rotation axis.
The driving axes are arranged in a straight line .

[0007]

Since the present invention is constructed as described above, after the counter weight guide rail is interposed between the moving piece and the fixed piece, the handle is turned around the third rotation axis.
Rotating in one direction and moving axis and moving piece via arm
Is moved in the direction of the fixed piece, and the counter is
When the weight guide rail is sandwiched between the side surfaces, the counterweight guide rail is pulled together with the movable piece in the direction of the fixed piece with the movement of the movable piece, is held between the movable piece and the fixed piece, and is centered. At this time, the first rotating shaft and the second
The rotation axis and the third rotation axis are aligned on a straight line .

In this manner, the counterweight guide rail can be clamped by an easy method of moving the moving shaft supporting the moving piece by the moving means without requiring any special operation such as the conventional bolt tightening. Can do it.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an elevator guide centering device according to the present invention will be described below with reference to the drawings.

FIG. 1 shows an embodiment of a guide rail centering device for an elevator according to the present invention, and is a plan view showing a state before the guide rail is held by a second jig, and FIG. 2 is shown in FIG. FIG. 3 is a plan view showing a state in which the guide rail is held by the second jig, and FIG. 3 is a plan view of the hoistway showing a state in which the guide rail for counterweight is being centered by the guide rail centering device in FIG. 1. It is.

The elevator, as shown in FIG.
Elevating body that ascends and descends, that is, the car 2 and a counterweight (not shown), a car guide rail 3 that guides the car 2 up and down, and a bracket that attaches the centered car guide rail 3 to the hoistway wall 4, a counterweight guide rail 5 for guiding up / down of the counterweight, and a bracket 6 for attaching the counterweight guide rail 5 to a hoistway wall.

[0012] Guide rail centering device 7 is applied to the thus constructed elevator includes a first jig 8 which engages the misuse guide rail 3 or is centered in the guide rail for counter weights It has a second jig 9 to be clamped and a bracket 10 for connecting the first jig 8 and the second jig 9 to each other.

As shown in FIGS. 1 and 2, the second jig 9 of the guide rail centering device 7 of this embodiment is attached to a bracket 10 and is attached to one side surface 5A of the counterweight guide rail 5. A fixing piece 11 having an abutting surface 11A, and a V-shaped support 1 attached to the fixing piece 11
2, a moving piece 13 having an abutment surface 13A for abutting against the other side face 5B of the counterweight guide rail 5, and a piece 12A of the V-shaped support 12 supporting the moving piece 13
, A moving shaft 14 that slides in a cylinder, a handle 16 rotatably supported by another piece 12B of the V-shaped support 12 via a shaft 15, and one end of the handle 16 via a shaft 17. Te, which via a shaft 18 to the other end edge portion of the moving shaft 14
And a connected semicircular arm 19 .

In this embodiment, first, the car guide rail 3 is centered and the hoistway wall 1 is
After being fixed to A, the first jig 8 is engaged and fixed to the car guide rail 3. Next, the other side surface 5B of the counterweight guide rail 5 is moved to the moving piece 13 as shown in FIG.
The handle 16 is rotated in the forward direction in this state. As a result, the moving shaft 14 moves in the direction of the fixed piece 11, and accordingly, the counterweight guide rail 5 is moved in the direction of the fixed piece 11, and as shown in FIG. The one side surface 5A of the weight guide rail 5 is brought into contact. That is, the counterweight guide rail 5 is fixed to the fixing piece 1.
1 and the moving piece 13. At this time, since the shaft 17 of the handle 16 is aligned with the shaft 18 and the shaft 15,
This fixed state is maintained even if the hand is released from the handle 16. When the first jig 8 is engaged and fixed to the car guide rail 3, the fixing piece 11 is already within the specified dimensions. Therefore, the counterweight guide rail 5 is moved to the state shown in FIG. At this time, the centering of the counterweight guide rail 5 is also completed. In this state, the counterweight guide rail 5 is fixed to the hoistway wall 1A by the bracket 6.

In the embodiment constructed as described above, the moving shaft 14 for supporting the moving piece 13 can be connected to the handle 16 without any special operation such as conventional bolt tightening.
Thus, the guide rails 5 for counterweight can be held by an easy method of moving with one touch.

[0016]

Since the present invention according to the present invention is configured as described above, without requiring any special operations, because it sandwiched attract easily guide rail for counter weights, Kauntau
Workability Eto guide rail centering work and it is possible to improve the work efficiency.
