DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lower centering fixing device for a hydraulic elevator.

[0002]

2. Description of the Related Art In the conventional centering work when installing a hydraulic elevator, a weight is attached to each predetermined centering position from an upper centering fixing device provided on the hoistway or at the top of the hoistway on the lower surface of the machine room slab. By hanging down the reference piano wire, and fixing each of the reference piano wires to each corresponding position of the lower centering device set at a predetermined height at the bottom of the hoistway,
Each required related dimension is obtained. That is, the conventional means is, as shown in FIG.
Opposite hoistway wall about 1 meter above (1)
Fixing material (3) (3) fixed using anchor bolts not shown in (2), or cradle (5) between fixing materials (3) (3) such as square members raised from the bottom (1) (5) is spanned and leveled, fixed, and then weighted from the upper centering template (not shown) to the end of the front positioning piano wire (6) (6).
(7) Attach and suspend the positioning material (8), wait for it to rest, and then position the positioning material (8) so that its front edge contacts the front positioning piano wire (6) (6). (5) Nail fixation between (5). This is the landing-side equipment centering piano wire. Further, in the same manner, align the piano wire (9) for centering the guide rail on the cage side with the marking on the front edge of each positioning material (8a), and also in front of the rear edge of the positioning material (8a) and one end of the positioning material (8b). Align the piano wire (10) (10) with the marking on the edge,
The centering required for elevator installation was obtained by the lower template and piano wire.

[0003]

As described above, the conventional centering work when installing a hydraulic elevator requires the lower centering mold plate to be provided about 1 meter above the bottom of the hoistway. The temporary storage space of the equipment is divided, and it is necessary to move while raising the lower centering template,
For this reason, the working efficiency of the worker is poor and there is a problem in terms of safety. In addition, this template is generally disposable at every construction, so that it is uneconomical.

[0004] In addition, when the conventional hydraulic elevator is installed, the piano wire is tensioned by a weight through the hole of the lower template rather than the upper template, so that when the equipment contacts during operation, the shear force acts on the piano wire and the wire breaks. There was also a risk of doing so.
