Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an apparatus for attaching equipment in an elevator hoistway, and more particularly to an apparatus for attaching equipment in an elevator hoistway, which is suitable when high precision is required for installation.

2. Description of the Related Art Conventionally, an elevator hoistway equipment mounting device for mounting elevator control and signal equipment is shown in FIGS. 1 and 2.

First, as shown in FIG. 2, the brackets 10 and 13 are fixed to the side wall of the hoistway 8 with anchor bolts 11 and 14, respectively, and the rails 3 and 12 are respectively attached to the brackets 10 and 13 using clips and bolts and nuts (not shown). Attach the car with the rail 3, and the counterweight 9 with the rail 12.
It is designed to guide you when going up and down.

In order to smoothly perform elevator control such as elevator speed control and operation, a first instrument 2 is attached to the car 1, and a second instrument 7 is attached to a bracket fixed to the rail 3. and electrically and mechanically engage instrument I.

By the way, as shown in FIG. 1, generally, a bracket 6 is brought into contact with the bottom surface of the rail 3, fixed with a clip 5 and bolts and nuts 4, and a first bracket attached to the heel (elevating body) 1 is attached to the bracket 6. A second instrument 7 was installed opposite the instrument 2.

However, with such a configuration, if the rigidity of the bracket 6 is weak, the tightening force of the clip 5 and the bolt/nut 4 will cause the bracket 6 to bend, which increases as it approaches its tip, as shown in the figure. , there is a possibility that the first appliance 2 and the second appliance 7 may interfere with each other when the car 1 is raised or lowered.

For this reason, some improvements have been made such as increasing the rigidity of the bracket 6 or arranging the first fixture 2 on both sides of the rail 3 as shown in Figure 2, but these measures alone are insufficient. However, especially in the latter case, there is a disadvantage that the number of brackets 6 increases and the installation work is time-consuming.

SUMMARY OF THE INVENTION An object of the present invention is to provide an elevator hoistway instrument mounting device that eliminates the drawbacks of the prior art described above and can maintain the position of the attached second instrument with high precision.

A feature of the present invention is that one end of the bracket for mounting the apparatus shown in FIG. 2 is fixed to a rail that guides a car that is moved up and down, and the other end is fixed to a rail that guides a counterweight that is moved up and down.

The present invention will be explained below using the embodiment shown in FIG.

2A, 2B, and 2C are the first instruments installed in line with Kato 1, and 7A, 7B, and 7C are the first instruments 2A, 2, respectively.
This is a second device placed at an appropriate position on each floor of the hoistway 8 to correspond to B and 2C.

This second instrument 7A, 7B, 7C is attached to the bracket 15.

One end of the bracket 15 is connected to the rail 3 that guides the car 1.
The clip 5 and the bolt/nut 4 are used to tighten and fix the screw to the bottom surface, and the other end is provided with a screw hole 16.

On the other hand, on the bottom of the rail 12 that guides the counterweight 9, a holder 18 is fastened and fixed with a clip 20 and a bolt/nut 21, and the tip of the holder 18 is placed opposite the screw hole 16. A hole 19 is provided.

A spacer 27 is inserted between the bracket 15 and the holder 18, and the bolt 17 is inserted through the hole 19 and screwed into the screw hole 16 to fix the other end of the bracket 15 to the holder 18.

However, the spacer 27 should have a thickness that does not cause the bracket 15 to bend.

According to the embodiment of the present invention described above, the mating dimensions between the first appliances 2At2B, 2C on the car 1 side and the second appliances 7A, 7B, 7C arranged in the hoistway are as follows:
Since both ends of 5 are fixed and no bending occurs,
The accuracy is high, and the first instruments 2A, 2Bt2C are the second instruments 7A t 7B.

When passing through section 7C, both electrical connections, electromagnetic coupling and mechanical switch actuation etc. are ensured.

As explained above, according to the present invention, since the bracket to which the second instrument is attached does not bend, the position of the second instrument can be maintained with high precision, and the position of the first instrument and the second instrument can be maintained with high precision. This has the remarkable effect of making it possible to confirm the opposite direction.
