The centering gauges for elevator guide rails proposed in these publications belong to one of the systems described below with reference to FIGS. 3 to 5.

Here, FIGS. 3 to 5 are explanatory diagrams showing the configuration of a conventionally proposed centering gauge for an elevator guide rail.

The system shown in FIG. 3 has a pair of ruler plates 11a, ll.

Centering surfaces 17b117b2 that are orthogonal to each other are formed on the respective surfaces.

Furthermore, with respect to the plumb lines 3a and 3b suspended in the vertical direction near mutually opposing wall surfaces in the hoistway,
The engaging portions 16a and 16b that are engaged for positioning are connected to the ruler plate 1.
1a and llb, respectively.

Further, on the ruler plate 11a, there is a fixture a for holding the ruler plate 11a and the guide rail 2a together.
A fixture 19b is attached to 1b to hold the ruler plate 11b and guide rail 2b together.

With the centering gauge shown in FIG. 3, the guide rail 2a,
In order to center and fix the guide rail 2b, a ruler plate 11a is attached to the mutually orthogonal sliding parts 18al and 18a2 of the guide rail 2a.
By bringing the centering surfaces 17at and 17a2 into contact with each other and operating the fixture 19a, the ruler plate 11a and the guide rail 2a are held fixed to each other. Similarly,

, 2b are adjusted and centered, and the guide rails 2a, 2b are fixed to the wall of the hoistway at the centered position.

The centering gauges shown in FIG. 4 are the guide rails 2a and 2b.
In order to accommodate cases where the spacing between
1a, llb are bolts 12a, 1 to the connecting rod 10.
2b has a fixed structure.

In this case, connecting rods 10 of different lengths are prepared in advance, and if the spacing between the guide rails 2a and 2b is different, a connecting rod 1o of a predetermined length is selected and a ruler plate 11a is selected.
, llb can be tightened and used with bolts 12a and 12b.

The centering gauge of the type shown in FIGS. 3 and 4 is arranged over a pair of guide rails 2a and 2b for centering, and therefore is large in size and has a drawback in terms of manufacturing cost.

In addition, it is necessary to perform centering while checking the mutual relationship between guide rails 2a and 2b. After centering guide rail 2a, centering guide rail 2b, and then centering guide rail 2a after centering guide rail 2b. The disadvantage is that the centering operation must be repeated, and the single centering operation is complicated and increases the working time.

A centering gauge of the type shown in Fig. 5 was proposed to solve these problems.
Each centering gauge can be performed independently.

That is, in this system, two plumb lines 3a are provided on the guide rail 2a side near the mutually opposing walls of the hoistway.
3b, and two plumb lines 3c and 3d are suspended on the guide rail 2b side. The ruler plates on the guide rail 2a side are the ruler plate 13a and the ruler plate 1.
The ruler plate on the guide rail 2b side is composed of two members, a ruler plate 13C and a ruler plate 13d.

In the centering gauge shown in FIG. 5, the guide rail 2a

In this state, fine adjustment centering of the guide rail 2a is performed so that the engaging portion 16a of the ruler plate 13a engages with the plumb line 3a, and the engaging portion 16b of the ruler plate 13b engages with the plumb line 3b. Perform the work, and place the guide rail 2 in the centered position.
Fix a.

Similarly, the orthogonal sliding portion 18b of the guide rail 2b
118b21, the ruler plate 13d is placed on the centering surface 17bl,
17bzt are fixed facing each other, and the ruler plate 13 is attached to the orthogonal sliding portion 18t)t and 18b22 of the guide rail 2b.
Centering surface 17t) and 17b22 are brought into contact with each other and fixed.

In this state, fine adjustment centering of the guide rail 2b is performed so that the engaging portion 16c of the ruler plate 13c engages with the plumb line 3c, and the engaging portion 16d of the ruler plate 13d engages with the plumb line 3d. Perform the work, and place the guide rail 2 in the centered position.
Fix b.

In this way, according to the centering gauge shown in FIG.
The guide rails 2a and 2b can be centered individually, and the entire gauge can be downsized.

<Problems to be Solved by the Invention> The centering gauge shown in FIG. 5 described above is small and advantageous in terms of manufacturing cost, and can center each of the guide rails 2a and 2b independently.

However, the ruler plates 13a and 13b are on the guide rail 2a,
Alternatively, the ruler plates 13c and 13d may not be completely fixed to the guide rail 2b. For this purpose, in order to finely adjust the position of the guide rails, the guide rails 2a, 2
If an impact is applied to b and the rail bracket with a hammer or the like, the ruler plates 13a, 13b and the ruler plates 13c, 13d may shift or come off, posing a problem in centering accuracy.

In addition, the ruler plates 13a and 13b are easily misaligned or removed during centering work, and the ruler plates 13a to 13d are held during the work. There was a problem.

The present invention was made in view of the current state of centering gauges for elevator guide rails of this type as described above, and its purpose is to achieve high centering accuracy even when the gauge is completely fixed to the guide rail. To provide an elevator guide rail centering gauge that can be easily attached to and removed from the guide rail, greatly improves the work efficiency of centering work, and has a compact shape that reduces manufacturing costs. be.

Means for Solving the Problems> In order to achieve the above object, the present invention provides a means for solving the problems, based on two plumb lines suspended in the vicinity of mutually opposing wall surfaces in a hoistway. On the other hand, in the centering gauge of an elevator guide rail used for centering and fixing each guide rail, the centering gauge is formed into a thick plate with an integral structure, and the sliding part of the guide rail is a recess into which the guide rail is inserted, an indicator attached at a position facing each of the two plumb-down lines and indicating the position of the plumb-down line with respect to the centering gauge, and a sliding part of the guide rail inserted into the recess. and fixing means for fixing to the centering gauge.
