JPS5921186Y2 - Positioning device for guide rail mounting frame for elevator car door - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a positioning device for installing a guide rail for an elevator car door, and more particularly to a positioning device that facilitates positioning and adjustment work.

The prior art will be explained based on FIG.

Figure 1 shows a front view of an elevator car,
The car frame is composed of a car frame 2 connected to the upper part by an upper beam 1 and the lower part by a floor frame 4, and 3 is a mounting base, which is connected to the car frame 2 and front mounting pillars 5 provided on the left and right sides of the entrance of the car. and are installed.

Further, the lower part of the front mounting pillar 5 is attached to the floor frame 4 to form a strong structure.

Reference numeral 8 denotes a door opening/closing drive device, which is installed on a base 7 supported at both ends by mounting bases 3, and automatically opens/closes a car door 10 at the entrance/exit portion of the elevator car via a door opening/closing link 9. Passengers in the elevator car are boarded and alighted from the elevator car, and the car door 10 has a hanger roller 12 that runs on a door rail 15 that is firmly attached to a door rail mounting frame 14 provided on the entrance/exit side of the car. The upper part is suspended to support the weight of the car door 10 by the banger 13, and the lower part is guided through the opening/closing position by inserting the guide shoe 11 into the guide groove provided in the sill 6.
Opening and closing of 0 is performed.

Door rail mounting frame 14 to which the door rail 15 is firmly attached
Bolts are attached at both ends to the left and right sides of the front mounting column 5, respectively, but since this is achieved only by the tightening friction strength of the bolts, the bolts are damaged due to the weight of the car door 10 and the vibration of the car door 10 when it is opened and closed. Door rail mounting frame 1 due to loosening etc.
4 is lowered, and the gap δ between the car door 10 and the sill 6 is reduced.
A stopper 16 is provided to position the door rail mounting frame 14 in order to avoid problems such as the lower part of the car door 10 main body hitting the sill 6 and the opening/closing operation of the door.

However, if the bolt 16 is welded and attached in advance when manufacturing the parts, that is, when manufacturing the front mounting post 5, manufacturing errors and
Or, due to assembly errors, the positions of the butts 16 provided on the left and right mounting front pillars 5 are different on the left and right, and the door rail 15 cannot be parallel to each other, so when assembling the door rail 1
Not only is it unavoidable to perform welding after adjusting the centering parallel level of door rail 15 in step 5, but if welding is done to ensure sufficient strength, thermal deformation due to welding will cause the door rail 15 to have to be adjusted to the centering parallel level. There was a drawback that it made me go crazy.

The purpose of the present invention is to eliminate the above-mentioned drawbacks, and the gist of the invention is to provide an adjustable stopper bolt for adjustment work as a means to eliminate thermal deformation caused by welding during assembly. This is an easy positioning device.

An embodiment of the present invention will be described below with reference to FIGS. 2 to 4.

In this figure, the same reference numerals as those shown in the conventional example of FIG. 1 are the same.

The adjustable butt 17, the stopper bolt 18, and the lock nut 19 are the key points of the present invention. It is firmly attached by welding on the opposing inner side of the column 5 at a position below the bolt tightening part between the rail mounting frame and the front column, and the stopper bolt 18 is attached during assembly.
By installing the door rail 15 and freely adjusting the adjustment dimensions, centering and parallel leveling of the door rail 15 can be easily done even if the mounting positions of the adjustable butts 17 on the left and right sides of the front mounting post 5 are different. In addition, since there is no need for welding during assembly, it is possible to prevent the parallel level of the door rail 15 from becoming out of order due to thermal deformation due to welding.

In addition, in the past, when welding overlay or thickening the abutment 16 in order to ensure strength, the abutment was attached to a surface facing the car door 10 with a small gap, so this abutment Since this may become an obstacle when opening, the spacing between the front mounting posts 5 must be widened.

On the other hand, if you try to use the pad 16 as it is thin, the rail mounting frame 14 in contact with the pad 16 will also become the end of the plate that forms it, making the support of the rail mounting frame 14 unstable and making adjustment work difficult. There was a troubling inconvenience.

In this regard, in the present invention, the stopper 17 is not attached to the surface of the front mounting pillar facing the car door, but to the side adjacent to that surface, and moreover, on the opposing inside sides of the two front mounting pillars, so that the car door can be opened and closed. Moreover, since the rail mounting frame 14 can also come into contact with the head of the stopper bolt 18 on its plate surface, stable support can be achieved and adjustment work can be facilitated.

As described above, according to the present invention, it is possible to eliminate deviations in the horizontal level of the door rail caused by distortions, bends, etc. due to thermal deformation due to welding during assembly. This has the effect of providing a positioning device for an elevator car employment guide rail mounting frame that facilitates the horizontal level adjustment work of the rail.
