DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator guide rail suspension apparatus used for mounting a guide rail.

[0002]

2. Description of the Related Art A conventional elevator guide rail suspension apparatus is disclosed in Japanese Utility Model Publication No. 55-41741, in which a threaded suspension is mounted and a shuttle mounting provided at the upper end of the suspension. A metal fitting, a fitting metal provided at the lower end of the hanging tool, a pin for connecting the connecting metal fitting to a hole formed at the upper end of the guide rail, an adjusting nut screwed to a screw of the hanging tool, And a metal support interposed between the nut and the floor of the elevator machine room to support the hanging tool.

[0003]

The conventional elevator guide rail suspension system is constructed as described above, so that the guide rail is supported at one point and the existing guide hole is used. If the position of the hole formed at the upper end of the guide rail is shifted even a little, the guide rail cannot be suspended vertically, and therefore, when the guide rail is installed and fixed, it is used as a reference line using a piano wire to secure the verticality. .

An object of the present invention is to provide an elevator guide rail suspension apparatus which can eliminate the operation of separately providing a reference line and can use the guide rail as a reference.

[0005]

According to the present invention , a guide rail is installed in an elevator shaft to achieve the above object.

[0006]

Since the elevator guide rail suspension apparatus according to the present invention is constructed as described above, the position of the suspension bolt is on a vertical line passing through the center of gravity when the guide rail is suspended vertically. The rails are in a vertical state, and brackets can be positioned using the guide rails as an installation reference.Therefore, there is no need to install the piano wire that has been used as a conventional installation reference, and there is no need to install and remove the piano wire. Can be.
Further, since the guide rail is supported by the rail base support member and the rail sliding portion support member, it is possible to prevent the guide rail from being twisted.

[0007]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a suspension device for a guide rail of an elevator according to an embodiment of the present invention, and FIGS. 2 and 3 are a front view and a side view showing the suspension device for a guide rail in a state where the guide rail is supported. .

The guide rail suspension device 11 is attached to the guide rail 10 by a guide rail base support member 11b.
The guide rail 10 is inserted between the guide rail slide member support member 11c and the guide rail slide member support member 11c, between the base 10a of the guide rail 10 and the guide rail base support member 11b, and between the guide rail slide member 10b and the guide rail slide member support member. The parts 11c are fixed to each other by fastening bolts.

When the guide rail 10 is suspended by the above-described guide rail suspension device 11, the shaft of the suspension bolt 11d is rotated.
Guide rails 10 for direction center line passing through the center of gravity of the whole
With hung vertically without tilting Kukoto, hanging guide rail 11 guide rail base and guide rail 10 supporting member 11b and the guide rail sliding portion support member 1
Since it is tied at 1c, the suspended guide rail 10 is not twisted. Thus, the guide rail 10 can be used as an installation reference without providing a reference for positioning the bracket or the like of the guide rail 10 using a piano wire as in the related art.

FIG. 4 is a side view showing a state in which a guide rail of an elevator guide rail suspension apparatus according to another embodiment of the present invention is suspended.

A guide rail suspension device 11 shown in FIG. 1 is attached to an upper portion of the first guide rail 10 and a suspension bolt 1 is provided.
Lift 1d. Next, the second guide rail 12 and the third guide rail 13 are connected to the first guide rail 10 using the guide rail connecting device 21.
