2. Description of the Related Art FIG. 8 shows, for example, JP-A-5-330757.
FIG. 6 is a perspective view of a conventional lower centering and fixing device for a hydraulic elevator disclosed in Japanese Patent Laid-Open Publication No. 2004-242242. In the figure, 11 is a car rail shock absorber base. The car-rail shock absorber base 11 is connected to the hall-side centering member 13 arranged in parallel with the car-rail shock absorber base 11 via connecting members 14 and 14. The distance between the car rail shock absorber base 11 and the landing side centering member 13 is changed to the car rail shock absorber base 11 by changing the positions of the bolts 16 inserted into the long holes formed in the connecting members 14, 14. The fixing positions of the connecting members 14 and 14 are shifted so as to be adjusted.

At one end of the car rail shock absorber base 11,
The jack mounting base 12 is connected via the connecting members 15, 15. The distance between the car rail shock absorber base 11 and the jack mounting base 12 is also adjusted by changing the positions of the bolts 17 inserted into the elongated holes formed in the connecting members 15, 15.

An upper template (not shown) is installed in the hoistway. From the upper template, piano wires 6 and 6 for positioning the entire surface and car wires 9 and 9 for centering the guide rails on the car side are provided.
Also, the jack rail centering piano wires 10 and 10 are suspended. The whole-positioning piano wires 6 and 6 are connected to the hall side centering member 13 via the tensile elastic members 19 and 19, and the car side guide rail centering piano wires 9 and 9 are the tensile elastic members 25 and 25. Is connected to the car rail shock absorber base 11, and the jack rail centering piano wires 10, 10 are connected to the jack mounting base 12 via the tensile elastic members 26, 26.

The tip ends of the tensile elastic members 19, 19 are engaged with the processing holes 18, 18 bored in the landing centering member 13. Further, the tip ends of the tensile elastic members 25, 25 are attached to the car rail shock absorber base 11 via the fastening members 23, 23. The tip end portions of the tensile elastic members 26, 26 are attached to the jack mounting base 12 via the fastening members 24, 24.
Mounted on

The lower centering and fixing device for a hydraulic elevator constructed as described above, when installed on the floor at the bottom of the hoistway,
Piano wire for full positioning 6, on the black mark on the standard floor
Positioned easily by aligning 6 Further, by connecting the car-side guide rail centering piano wires 9 and 9 and the jack rail centering piano wires 10 and 10 to the car rail shock absorber base 11 and the jack mounting base 12, respectively, it is necessary to install the elevator. The size of each part for centering is obtained.

[0007]

However, since the connection position of the jack rail centering piano wires 10, 10 to the jack mounting base 12 cannot be finely adjusted, the jack rail centering piano wire is adjusted each time the centering is performed. The interval (L) of 10, 10 had to be set correctly. As a result, there is a problem in that workability is deteriorated and incorrect centering is performed.

Therefore, as shown in FIG. 9, the upper flange 12a of the jack mounting base 12 is sandwiched, and the two fastening members 28, 28 are provided at one end of the clips 27a, 27a with variable facing intervals. Attach and clip 27
There is one in which the distance between the jack rail centering piano wires 10 and 10 is adjusted by changing the facing distance between a and 27a.

However, in such a lower centering and fixing device for a hydraulic elevator, the clips 27a, 27a are moved independently of each other while the facing distance between them is changed and aligned. As a result, it takes a lot of work to accurately set the interval between the jack rail centering piano wires 10 and 10, and there is a problem that workability cannot be sufficiently improved.

The present invention has been made in view of the above points, and provides a lower centering and fixing device for a hydraulic elevator, which can easily perform an accurate centering operation with high workability. is there.
