Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a guide rail centering adjustment liner used for centering adjustment of an elevator guide rail.

[0002]

2. Description of the Related Art When installing a guide rail for guiding a car and a guide rail for guiding a counterweight in a hoistway, it is required to vertically install these guide rails. A guide rail centering adjustment liner is used for such centering adjustment of the guide rail.

FIG. 8 is a side view for explaining centering adjustment of a guide rail using a conventional guide rail centering adjustment liner.

Generally, in an elevator, as shown in FIG. 8, a guide rail 1 for guiding an elevating body (not shown), rail brackets 2, 3 for supporting the guide rail 1, and bolts respectively fastened to the rail brackets 2, 3 are provided. 4, 6
It also has nuts 5 and 7, and wall-side brackets 9 and 10 fixed to the wall 8 of the building. In the elevator configured as described above, the guide rail centering adjustment liners 11 and 12 provided between the guide rail 1 and the rail brackets 2 and 3 are used to perform the guide rail centering adjustment. Done. And conventionally, such centering adjustment liners 11 and 12 are formed in a flat plate shape having a predetermined plate thickness.

In the conventional work, when the verticality of the erected surface of the rail brackets 2 and 3 facing the guide rail 1 is not sufficiently obtained, that is, when the bending occurs, as shown in FIG. As shown, one or more centering adjustment liners 11 are inserted between the rail bracket 2 above the bolt 4 and the guide rail 1, or the rail bracket 3 below the bolt 6 and the guide rail 1 are inserted. Between 1
The adjustment is performed by inserting one or a plurality of centering adjustment liners 12.

[0006]

By the way, in the above-mentioned conventional centering adjustment liner, when the centering adjustment liner 11 is inserted above the bolt 4, the bolt 4 is used for fine adjustment. Even if it is loosened, since the shape of the gap formed by the guide rail 1 and the rail bracket 2 is a downward recess, the centering adjustment liner 11 can be prevented from falling down, but the centering adjustment liner can be prevented. When the bolt 6 is inserted below the bolt 6 as shown in FIG. Therefore, it is necessary to adhere the centering adjustment liner 12 to the rail bracket 3 by spot welding or the like. Therefore, there is a problem in that the centering adjustment liner 12 needs to be mounted with difficulty, and improvement in workability and work efficiency cannot be expected.

In particular, when finely adjusting the guide rail during centering, it may be necessary to reduce the number of centering adjusting liners once adjusted, and in such a case, as described above, the centering adjusting liner is required. If the rail was attached to the rail bracket by spot welding or the like, this welding had to be solved, and the work could be even more troublesome.

The present invention has been made in view of the above-mentioned problems, and an object thereof is to perform centering adjustment of a guide rail,
It is to provide a guide rail centering adjustment liner that can be easily attached and detached.

[0009]

In order to achieve this object, the present invention is provided between a guide rail that guides an elevator body of an elevator and a rail bracket that supports the guide rail. A guide rail centering adjustment liner used for centering adjustment is provided with an engaging portion engageable with the rail bracket.

[0010]

Since the present invention is configured as described above, when the guide rail is bent in the vertical direction during centering adjustment of the guide rail, the engaging portion of the centering adjustment liner is engaged with the rail bracket. The centering adjustment liner is interposed between the rail bracket and the guide rail, and the centering adjustment liner is prevented from falling off. On the other hand, when removing the centering adjustment liner, the engagement of the engaging portion with the rail bracket is released, and the liner is removed from the rail bracket. In this way, the centering adjustment liner can be easily attached and detached by being attached by the engagement of the engagement portion.

[0011]

Embodiments of the guide rail centering adjustment liner of the present invention will be described below with reference to the drawings. FIG. 1 shows an embodiment of a guide rail centering adjustment liner of the present invention, and is a perspective view showing a state where the centering adjustment liner is mounted.
1 is a side view of a state where the centering adjustment liner of FIG. 1 is mounted, FIG. 3 is a perspective view of the centering adjustment liner of FIG. 1, and FIG.
1 is a side view of the centering adjustment liner of FIG. 1, FIG. 5 is a side view showing another state of the centering adjustment liner of FIG. 1, and FIG.
FIG. 6 is a side view showing another state of the centering adjustment liner of FIG.
The same components as those shown in FIG. 8 described above are designated by the same reference numerals. That is, 1 is a guide rail, 3 is a rail bracket, 6 is a bolt, 7 is a nut, 8 is a wall, 1
Reference numeral 0 is a wall side bracket.

The centering adjustment liner 20 of this embodiment is shown in FIG.
As shown in FIG. 4 to FIG. 4, a U-shaped engaging portion 21 that can engage with the rail bracket 3 is provided, and
It has an overlapping portion 22 that is folded in steps. Such a centering adjustment liner 20 can be formed by cutting a single flat plate and bending the center portion.

In this embodiment, when the verticality of the erected surface of the rail bracket 3 facing the guide rail 1 is not sufficiently obtained, that is, when a bend is generated, FIG. 1 and FIG. As shown in, the centering adjustment liner 20 is inserted between the rail bracket 2 above the bolt 6 and the guide rail 1, and the engaging portion 21 is engaged with the upper end of the rail bracket 3. As a result, even if the bolt 6 is loosened during the fine adjustment, the centering adjustment liner 20 does not come off because the engaging portion 21 is engaged with the rail bracket 3. Further, when it is required to remove the centering adjustment liner 20 that is once installed, by loosening the bolt 6 and releasing the engagement between the upper end of the rail bracket 3 and the engaging portion 21,
The centering adjustment liner 20 can be pulled out from below the bolt 6.

In the embodiment thus constructed, the centering adjusting liner 20 is mounted by the engagement of the engaging portion 21, so that it can be easily attached and detached.

In this embodiment, the centering adjustment liner 2 is used.
0 has a two-stage overlapping portion 22, but depending on the size of the gap between the rail bracket 3 and the guide rail 1, one overlapping portion may be provided as shown in FIG. As shown in the figure, the structure may be such that the overlapping portion is not provided. These can be obtained by appropriately cutting unnecessary portions. Also,
In this embodiment, the centering adjustment liner 20 whose main portion is located below the bolt 6 has been described. However, as shown in FIG. 8 described above, the main portion of the centering adjustment liner is arranged above the bolt. If desired, it is possible to use a configuration in which only a flat plate-shaped upper end portion is formed in a U shape.

FIG. 7 is a perspective view showing another embodiment of the guide rail centering adjustment liner of the present invention.

As shown in FIG. 7, the centering adjustment liner 23 of another embodiment is provided with an engaging portion 24 that can engage with the rail bracket 3, and this engaging portion 24 stands upright of the rail bracket 3. It is configured to be fitted into the installation portion from above and the lower portion thereof is supported by the bottom surface of the rail bracket 3.

Similarly, the other embodiments configured as described above also have
The centering adjustment liner 23 can be easily attached and detached by being attached by the engagement of the engagement portion 24.

[0019]

Since the present invention is configured as described above, the centering adjustment liner can be easily attached and detached during the centering adjustment of the guide rail. Therefore, the guide rail centering work described above is performed. There is an effect that the efficiency and work efficiency can be improved.
