Embodiment 1 FIG.
FIG. 1 is a configuration diagram showing a main part of an elevator including an elevator governor rope steadying device (hereinafter abbreviated as a rope steadying device) according to Embodiment 1 of the present invention.
In this elevator, a speed governor 3 is installed in a machine room 2 above the hoistway 1. A tension wheel 5 is installed in the pit 4 below the hoistway 1. A governor rope 6 is wound between the tension wheel 5 and the governor 3.
Car guide rails 7 are attached to the opposing wall surfaces of the hoistway 1 so as to extend in the vertical direction. The car 8 guided by the pair of car guide rails 7 faces and stops at the landing door 10 at the entrance / exit of the landing 9 on each floor.

The governor rope 6 is interlocked with the movement of the car 8, and the rope catch (not shown) of the governor 3 is adjusted before the descending speed of the car 8 exceeds a predetermined multiple of the rated speed. The speed rope 6 is restrained, and as a result, an emergency stop device (not shown) attached to the lower part of the car 8 is operated, and the car 8 is forcibly stopped.

A rope steadying device 11 is provided between the car guide rail 7 and the governor rope 6.
2 is a front view showing the rope steadying device 11, FIG. 3 is a plan view of FIG. 2, and FIG. 4 is an exploded perspective view showing the rope steadying device 11 of FIG.
This rope steadying device 11 includes a bracket 13 in surface contact with the flange 12 of the T-shaped car guide rail 7, a rail clip 14 that fixes both ends of the flange 12 using bolts 15 and nuts 16, and a bracket. And a rope swinging member 17 extending linearly from 14 to the governor rope 6.
In this embodiment, the rope steadying device 11 is fixed to the car guide rail 7 by rail clips 14 at the four corners of the bracket 13. That is, the rope steadying device 11 is fixed to the car guide rail 7 by sandwiching the flange 12 between the rail clip 14 and the bracket 13 and tightening the rail clip 14 and the bracket 13 with the bolt 15 and the nut 16. In FIG. 4, the other three rail clips 14 and bolts 15 and nuts 16 corresponding to the rail clips 14 are omitted.

The bracket 13 is formed with a raised portion 18 which is a distance adjusting portion extending in the horizontal direction. The rope steadying member 17 is moved along the horizontal direction of the raised portion 18 so that the distance from the rope steadying member 17 protruding from the bracket 13 to the governor rope 6 is adjusted.
When viewed along the vertical direction (in the direction of arrow A in FIG. 4) at the end of the rope stabilizer member 17 on the governor rope 6 side, a closed space is formed and viewed along the horizontal direction. (In the direction of arrow B in FIG. 4), an engaging portion 20 is provided in which an opening 19 into which the governor rope 6 can be taken in and out is formed.
The engaging portion 20 surrounds the anti-rail side rope portion 6 a on the side opposite to the car guide rail 7 in the governor rope 6.

The rope steadying device 11 having the above configuration is attached to the car guide rail 7 in the following procedure.
First, the rope steadying member 17 is made parallel to the anti-rail side rope portion 6a (see FIG. 5A).
Next, the rope steadying member 17 is translated and the anti-rail side rope portion 6a is passed through the opening 19 (see FIG. 5B).
Thereafter, after the rope steady member 17 is rotated clockwise (see FIG. 5C), the rope steady member 17 is attached to the bracket 13 from the end of the rope steady member 17 opposite to the engaging portion 20. To be inserted into the ridge 18. At this time, the rope steady member 17 is inserted in accordance with the distance from the rope steady member 17 protruding from the bracket 13 to the anti-rail side rope portion 6a of the governor rope 6.
Next, the bracket 13 is aligned with the car guide rail 7 and the rope steadying member 17 is fixed to the bracket 13 by welding or the like. Finally, the four corners of the flange 12 of the car guide rail 7 are connected to the rail clip 14. The rope steady rest device 11 is fixed to the car guide rail 7 by clamping the rail clip 14 and the bracket 13 with bolts 15 and nuts 16 respectively.

According to the rope steadying device 11 of the first embodiment, the engagement part 20 of the rope steadying member 17 is formed with a closed space when viewed along the anti-rail side rope part 6a, and the anti-rail side is formed. When viewed in a direction perpendicular to the rope portion 6a, an opening 19 is formed through which the anti-rail side rope portion 6a can be taken in and out.
Therefore, the rope steady member 17 moves the rope steady member 17 so that the anti-rail side rope portion 6a passes through the opening 19 of the engaging portion 20 when restraining the non-rail side rope portion 6a. Thus, the rope steadying member 17 can automatically restrain the anti-rail side rope portion 6a, and this workability is improved.

Moreover, since the rope steadying device 11 includes the bracket 13 that is fixed to the car guide rail 7 using the rail clip 14, the rope steadying apparatus 11 is securely fixed to the car guide rail 7 via the bracket 13.

Further, since the bracket 13 is formed with a raised portion 18 which is a distance adjusting portion that can freely move the rope steadying member 17 in the horizontal direction, it is fixed to the anti-rail side rope portion 6a and the guide rail 7 for the car. The variation in the distance between the bracket 13 and the bracket 13 is easily adjusted by moving the rope steady member 17 horizontally.
Further, the vertical position of the engaging portion 20 can be finely adjusted by changing the tightening amounts of the left and right bolts 15 and nuts 16 in FIG.

Embodiment 2. FIG.
6 is a perspective view showing a rope steadying member 17A of the rope steadying device 11 according to Embodiment 2 of the present invention, FIG. 7 is a plan view of FIG. 6, and FIG. 8 is a front view of FIG.
