Description

[Detailed Description of the Invention] This invention relates to a rail fixing device provided in an elevator hoistway.

First, a conventional elevator rail fixing device will be explained with reference to FIGS. 1 to 3.

In the figure, 1 is the elevator hoistway, 2 is the car, 3 is the counterweight, 4 and 4A are the rails that guide the car 2, 5 and 5A are the rails that guide the counterweight 3, and the car 2 and the counterweight 3 are Rails 4 connected by ropes (not shown)
．． You will be guided up and down by 4A and 5.5A.

Reference numeral 6 designates the entrance/exit door of the car 2, and the solid line shown in FIG. 1 indicates the fully closed state, and 6A indicates the fully open state of the entrance/exit door 6 with a chain line.

Reference numeral 7 denotes a door device for opening and closing the entrance/exit door 6, which is normally installed so as to protrude to the left from the car 2 shown in FIG. 1 in order to hold the entrance/exit door 6A fully open.

Therefore, in order to effectively utilize the space in the elevator hoistway 1, the counterweight 3 is placed between the cars 2 and 3 as shown in FIG.
It is often installed at the rear left side of the

Note that if the opening direction of the entrance door 6 is opposite to that shown in FIG. Numeral 8 is a fixing fitting for fixing the rails 4 and 5 to the hoistway 1, which is often installed.Similarly, 8A is a fixing fitting for the rail 4A, 8B is a fixing fitting for the rail 5A, and the fixing fitting 8 is It is attached to the hoistway inner wall IA with anchor bolts 9.

Rails 4 and 5 are equipped with rail clips IO, 10A bolts and nuts 11. It is fastened to the fixture by IIA.

The fixing fitting 8 is composed of a wall fitting 12 made of angle iron and a rail fitting 13 made of angle iron processed into a U-shape, which are integrated by welding 14.14A during manufacture.

That is, since the rails 4 and 5 are normally attached at intervals of 2 to 3 m over the entire height of the elevator hoistway 1, several dozen fixing fittings 8 are used per elevator.

On the other hand, since the construction error of the offset IA in the hoistway is generally about ±20 rran with respect to the vertical line, the dimension H shown in Fig. 2 from the inner wall IA of the hoistway to the rail 4 for all the mounting locations of the fixing bracket 8 for each elevator. After actually measuring, the fixing fittings 8 are manufactured individually based on this H dimension.

In addition, the dimension H□ from the center of rail 4 to rail 5 and the dimension H2 from the center of rail 5 to rail 4 shown in FIG.
is a constant size for each elevator model, so it is not affected by construction errors of the hoistway inner wall IA.

In addition, in order to compensate for manufacturing errors in the fixing fitting 8 and inclination of the hoistway inner wall 1A, a fine adjustment liner 15 is provided between the hoistway inner wall IA and the mold fitting 12, and a fine adjustment liner 15 is provided between the rail 4.5 and the rail fitting 13.
Fine adjustment liners 15A and 15B are interposed between them, respectively.

In addition, since the fixing fittings 8 are manufactured individually after measuring the H dimension, not only does it take a long time to manufacture them, but the work order at the elevator installation site becomes complicated, which reduces work efficiency. there were.

This invention solves the above-mentioned drawbacks, and is an elevator that can efficiently fix the rail in a predetermined position by using a molded fitting with a long horizontal surface and a rail fitting whose position is adjusted and fixed on this horizontal surface. The present invention aims to provide a rail fixing device.

An embodiment of this invention will be described below with reference to FIGS. 4 to 7.

In the figure, the same symbols as in Figures 1 to 3 indicate corresponding parts, and 16
is a type fitting, which is attached to the inner wall IA of the hoistway and has an L-shape with a piece 16A and a horizontal surface 16B protruding toward the rail 4 side.
The piece 16A is provided with a long hole 20 for fixing the mold fitting 16 to the hoistway wall IA with an anchor bolt 9.

Reference numeral 17 denotes a rail fitting, and the angle iron is bent into a U-shape and has a vertical surface 17A at a portion in contact with the rail 4, and side sides 17B and 17C that engage with a horizontal surface 16B of the wall side fitting 16.

Then, attach rail 4 to rail clip 1 on vertical surface 17A.
0, an engaging part 18A formed from a hole for fixing with bolts and nuts 11 is provided, and the rail 5 is fixed on the vertical surface of the side 17B with the rail clip 10A1 bolt and nut I.
An engaging portion 18B consisting of a hole for fixing with IA is provided.

Furthermore, an engaging portion 18C consisting of a hole, which is the same as the retaining portion 18B and is opposite to the retaining portion 18B, is provided on the vertical surface of the side 17C.

Although the engaging portions 18B and 18C are illustrated as round holes, they may be made longer in order to absorb manufacturing errors in the rail fitting 17.

That is, the centering and fixing work of the rails 4 and 5 is performed as follows.

First, the anchor bolt 9 is installed on the inner wall IA of the hoistway, and the piece 16A of the mold fitting 16 is fixed thereto.

Next, attach the sides 17B and 17C of the rail fitting 17 to the mold fitting 1.
Place it on the horizontal surface 16B of 6, hand vise, clamp (
(not shown) or the like.

Next, the rail 4 is fixed to the vertical surface 17A of the rail fitting 17 using the rail clip 10, bolt and nut 11.

Thereafter, the rail 4 is centered using a piano wire (not shown) or the like as a reference.

This centering is performed by hitting the rail fitting 17 with a hammer or the like to move the rail 4 to a predetermined position.

After the centering of the rail 4 is completed, welding 19, 19A is performed to integrate the mold fitting 16 and the rail fitting 17.

Next, the rail 5 is fixed with the rail clip 10A1 bolt and nut IIA.

Note that the centering of the rail 5 is performed using a piano wire (not shown) or the like as a reference, but since the two dimensions shown in FIG.
A fine adjustment liner 15B for absorbing manufacturing errors of the rail fitting 17 without being affected by construction errors, inclinations, etc. of A is easily inserted between the rail 5 and the side 17B of the rail fitting 17. Can be centered and fixed.

In addition, adjustment of the H dimension due to construction errors of the hoistway wall IA is done by adjusting the horizontal surface 16B of the mold fitting 16 and the rail fitting 1 shown in FIG.
This is done by adjusting the dimension h of the engaging portion with the sides 17B and 17C of 7.

The minimum H dimension due to this adjustment is when the h dimension becomes the maximum, that is, when the length of the horizontal surface 16B becomes equal to the length h of the horizontal surface 16B, and the maximum H dimension is when the h dimension becomes the minimum,
The minimum h dimension is determined by the strength that the welds 1B and 18A can withstand against the load applied to the rail 4.5 due to earthquakes, etc., and is usually about 5017011.

Therefore, the larger the length h of the horizontal surface 16B of the mold fitting 16, the greater the adjustment range of the H dimension, and
The length of the mold fitting 46 is preferably long enough to allow the installation of the anchor bolt 9, and there is no need to make it unnecessarily long. Therefore, it is preferable that the mold fitting 46 has a unequal shape with a short piece 16A and a long horizontal surface 16B.

Furthermore, by providing the engaging portion 18C on the side 17C of the rail fitting 17, it is possible to install the counterweight 3 in the case of the arrangement of the counterweight 3 shown in FIG. Since the rail fitting 17 can be used in any elevator where the counterweight 3 is installed, the same guide rail fixing device can be used regardless of the installation position of the counterweight 3, so the type of rail fitting 17 can be used. It can be done less.

In addition, as a method for integrating the wall fitting 16 and the rail fitting 17, there are other methods other than welding.
and the side 17B of the rail fitting 17.

Even if one of the engaging parts of 17C is made with a round hole, one with an elongated hole, or both with elongated holes, etc., and the bolts and nuts are connected, the same effect as in the embodiments shown in Figs. 4 to 7 can be achieved. It is clear that this can be obtained.

As explained above, this invention is constructed so that the rail is fixed by a wall fitting provided with a horizontal surface having a relatively long protruding dimension, and a rail fitting fixed by adjusting the position on this horizontal surface. The work to actually measure the dimension H from the inner wall of the hoistway to the rail is no longer necessary, and the time required for this work is eliminated, thereby shortening the elevator installation period.

In addition, with this invention, the wall fittings and rail fittings that make up the rail fixing device can be mass-produced before the installation work begins, reducing production costs. Since this is not necessary, installation work becomes easier.

In addition, since engaging parts are provided on both sides of the rail fitting, the same rail fitting can be used regardless of the installation position of the counterweight, which reduces the number of types of parts, making it possible to produce larger quantities, and stocking parts. The effect of reducing costs can also be obtained.
