Embodiments of an elevator guide rail fixing device according to the present invention will be described below with reference to the drawings.

As shown in FIGS. 1 and 2, the elevator guide rail fixing device according to the present embodiment is connected to the first vertical portion 3 a and the first vertical portion 3 a that are fixed to the hoistway wall 1 by the anchor bolt 2. A wall-side fixture 3 having a first horizontal portion 3b. Further, in the present embodiment, the second horizontal portion 7a welded to the first horizontal portion 3b of the wall-side fixture 3 and the passenger car, the counterweight, etc., which are connected to the second horizontal portion 7a and constitute a lifting body. Guide rail 6 that guides the rail clip 5
The rail side fixing bracket 7 having the second vertical portion 7b attached by the above is provided.

As shown in FIG. 3, the wall-side fixture 3 provided in the present embodiment is provided at the end of the first horizontal portion 3 b on the guide rail 6 side, and does not interfere with the car 8 or the hoistway device 9 ( (See Figure 1)
The first protrusion 3d1 and the second protrusion d2 that protrude toward the guide rail 6 are provided. Also,
As shown in FIG. 3, the wall-side fixing bracket 3 is formed between the first projecting portion 3d1 and the second projecting portion 3d2, and has a recess 3e into which the back surface portion 6a of the guide rail 6 can be inserted. I have. As shown in FIG. 1, the dimension between the outer end portions of the first projecting portion 3d1 and the second projecting portion 3d2 that are located on the sides away from each other is set to be larger than the width dimension of the back surface portion 6a of the guide rail 6. Has been. The first vertical portion 3a is formed with a bolt hole 3c into which the above-described anchor bolt 2 is inserted.

Moreover, as shown in FIG. 4, the rail side fixing metal fitting 7 which concerns on this embodiment differs in the length dimension of the 2nd horizontal part 7a, and the length dimension of the 2nd vertical part 7b. For example, the length dimension of the second vertical portion 7b is set longer than the length dimension of the second horizontal portion 7a. Moreover, the hole part 7c which can insert the rail clip 5 mentioned above is formed in the 2nd vertical part 7b of this rail side fixing metal fitting 7, and the rail clip 5 mentioned above is also inserted in the 2nd horizontal part 7a. A possible hole 7d is formed.

As shown in FIGS. 1 and 2, when the guide rail 6 is fixed at a position closest to the hoistway wall 1, the rail clip 5 is inserted into the hole 7 c of the second vertical portion 7 b of the rail side fixing bracket 7. By being inserted, the guide rail 6 is fixed to the rail side fixing bracket 7.

Unlike the guide rail fixing form shown in FIGS. 1 and 2, as shown in FIGS. 5 and 6, the guide rail 6 is fixed at a position farthest from the hoistway wall 1 as shown in FIG. The second horizontal portion 7a shown in FIGS. 1 and 2 of the rail-side fixing bracket 7 shown is utilized as the third vertical portion 7f.
The second vertical portion 7b of the rail side fixing bracket 7 shown in FIGS. 1 and 2 is utilized as the third horizontal portion 7e. Therefore, the guide rail 6 is fixed by the rail clip 5 inserted into the hole 7d of the third vertical portion 7f of the rail side fixing bracket 7.

For example, the operation of fixing the guide rail 6 to the fixing form shown in FIGS. 1 and 2 is performed according to the following procedure.

First, the first vertical portion 3 of the wall-side fixing bracket 3 in a state where the wall-side fixing bracket 3 is positioned.
An anchor bolt 2 is driven into the bolt hole 3c of a, and the wall side fixing bracket 3 is fixed to the hoistway wall 1 by the anchor bolt 2.

Next, the rail clip 5 is inserted into the hole 7 c of the rail side fixing bracket 7, and the guide rail 6 is gripped by the rail clip 5.

In this state, the position of the guide rail 6 is adjusted by moving the rail-side fixing bracket 7 relative to the wall-side fixing bracket 3, that is, in the horizontal plane, in the front-rear direction and the left-right direction. At this time, the back surface portion 6 a of the guide rail 6 is inserted into the recess 3 e of the wall-side fixing bracket 3.

After adjusting the position of the guide rail 6, both end portions of the second horizontal portion 7 a of the rail side fixing bracket 7 and the first horizontal portion 3 b of the wall side fixing bracket 3 are welded to form the welded portion 4. In this way, the guide rail 6 is fixed to the hoistway wall 1.

When the guide rail 6 is fixed to the fixing form shown in FIGS. 5 and 6, the guide rail is fixed to the third vertical portion 7f (second horizontal portion 7a in FIGS. 6 with the third horizontal portion 7e (the second vertical portion 7b in FIGS. 1 and 2) placed on the first horizontal portion 3b of the wall-side fixture 3 in the horizontal and horizontal directions. To adjust the position of the guide rail 6. At this time, the back surface portion 6 a of the guide rail 6 is in a state of being detached from the concave portion 3 e of the wall-side fixture 3.

After the position of the guide rail 6 is adjusted, the first horizontal portion 3b and the first projecting portion 3d of the wall-side fixture 3 are provided.
1, both sides of the portion of the third horizontal portion 7e located on the second projecting portion 3d2 are fixed via the welded portion 4 formed continuously as shown in FIG. In this way, the guide rail 6 is fixed to the hoistway wall 1.

As described above, according to this embodiment, when the guide rail 6 is fixed, as described above,
On the first horizontal portion 3b of the wall-side fixing bracket 3 and on the first protruding portion 3d1 and the second protruding portion 3d2 located at the end of the first horizontal portion 3b on the guide rail 6 side, the rail-side fixing bracket 7 is provided. Second horizontal part 7
a or the third horizontal portion 7e is installed, and the back surface portion 6a of the guide rail 6 is fixed to the wall side fixing bracket 3
The position of the guide rail 6 is adjusted so as to move in the recess 3e or to be detached from the recess 3e. After the position adjustment, the second horizontal portion shown in FIGS. 7a and the first horizontal portion 3b of the wall-side fixing metal fitting 3 are welded, or the third horizontal portion 7e, the first horizontal portion 3b, the first protruding portion 3d1, and the second protruding portion 3d2 shown in FIGS. It is supposed to be welded.

Thereby, this embodiment can ensure easily the welding allowance of the rail side fixing metal fitting 7 and the wall side fixing metal fitting 3 and the position adjustment allowance of the guide rail 6 simultaneously, and the guide rail 6 can be set in the hoistway. The efficiency of the fixing work to fix can be improved.

In the embodiment shown in FIGS. 1 and 2, the second horizontal portion 7 of the rail-side fixing bracket 7 is used.
Since the length dimension of the second vertical portion 7b is set longer than the length dimension of a, the guide rail 6 shown in FIGS. By changing the form, the guide rail 6 can be fixed as shown in FIGS.
Thereby, a sufficiently long position adjustment margin of the guide rail 6 can be secured.

In addition, the 1st protrusion part 3d1 of this embodiment and the 2nd protrusion part 3d2 will fulfill | perform the function, if it has a dimension larger than the width dimension of the back surface part 6a of the guide rail 6. FIG. That is, if the back surface portion 6a of the guide rail 6 can be positioned in the recess 3e, the distance between the outer end portions of the first protrusion portion 3d1 and the second protrusion portion 3d2 is larger than the width dimension of the rail side fixing bracket 7. This is because the welded portion 4 can be formed between the first projecting portion 3d1, the second projecting portion 3d2 and the rail-side fixing bracket 7 on the back side of the rail-side fixing bracket 7 even if the dimension of the rail-side fixing bracket 7 is small. However, the first protrusion 3d1,
If the dimension between the outer end portions of the second protrusion 3d2 is formed so as to be larger than the width dimension of the rail-side fixing bracket 7, the first protrusion 3d1 and the second protrusion 2d are formed on the surface side of the rail-side fixing bracket 7. Since the work of forming the welded portion 4 between the protruding portion 3d2 and the rail side fixing bracket 7 can be performed,
The workability is improved, and the working time can be shortened, so that the cost can be reduced.
