Description

[Detailed Description of the Invention] This invention relates to a centering device for an elevator guide rail.

An elevator guide rail centering device according to a reference example will be explained with reference to FIG.

In Fig. 1, 1.1' is a guide rail, 2, 2' are piano wires for centering, 3 is the main rod of the centering device, and 4 is the main rod 3.
Levels 5 and 5' are ruler plates fixed to both ends of the main rod 3.

These ruler plates 5° 5' have the guide rails 1, 1
’ by touching the rail surfaces of guide rails 1, 1.
'A stopper 5at53' that sets the distance between the two, and ruler surfaces 5b, 5 that regulate the inclination between the guide rails 1, 1' by abutting the sides of the guide rails 1, 1'.
gage notch 5ct5C, which is formed by cutting out b' into a rectangular shape and is loosely fitted to the piano wires 2 and 2'.
' are formed, and markings 5d for positioning the piano wires 2, 2' are formed around the notches 5c, 5C'.
5d' is formed.

Reference numerals 6 and 6' designate attachment mechanisms for temporarily attaching the centering device to the guide rail 1.1'.

The guide rail centering device shown in FIG. The formed ruler surface 5b.

5b' are temporarily attached to the sides of the guide rails 1 and 1'.

Thereafter, the mounting mechanism 6, 6' is attached to the flange part of the guide rail 1.1', and by tightening the nut, the rail surface of the guide rail 1, 1' abuts against the stopper 5aw53', and the rail side surface is brought into contact with the ruler surface 5b. , 5b', and at the same time check the level using the spirit level 4.

Next, as described above, the centering device is attached to the guide rail 1,
1' with the gauge notch 5C95C'
Positioning marking 5d consisting of peripheral marking lines, etc.
, 5d' are aligned and positioned with the centering piano wire 2°2', then the guide rail 1.1' is fixed to the bracket, and then the jig is removed.

However, the size of the guide rail varies depending on the type of elevator, and it may be necessary to shift the position of the piano wire by a certain amount of time, making the installation work cumbersome and easy to make mistakes.

This idea was made in order to solve the above-mentioned problem. Even if the guide rail size is different, it is not necessary to move the position of the centering piano wire, which is the reference for installation, and the installation process is easy. It is an object of the present invention to provide a centering device for an elevator guide rail that can prevent mistakes.

An embodiment of this invention will be described below with reference to FIG.

In FIG. 2, 5e is a screw hole opened in the ruler surface 5b of the ruler plate 5, 7 is a block gauge installed on the ruler surface 5b, and 8 is a block gauge installed on the ruler surface 5b through the hole 7a of the block gauge 7. A screw for fastening and fixing.

In this embodiment, the configuration other than those described above is the same as that of the reference example shown in FIG. 1 and described above, so the same parts are given the same reference numerals in FIG. 2 and the explanation will be omitted.

It goes without saying that the block gauges 7 are fixed to the ruler surfaces of the ruler plates at both ends of the main rod.

The guide rail centering device configured as above is
Block gauges 7 of different thicknesses are fixed to the ruler surface 5b according to the size of the guide rail 1 - and if the block gauges 7 are unnecessary, they can be removed.
Since the distance between the ruler surface 5b and the centering piano wire can be adjusted, the position of the centering piano wire 2 can be made constant.

Note that the guide rail centering operation performed by this guide rail centering device is the same as that of the reference example described above.

In this invention, the main rod may be fixed to the ruler plate so that it can be replaced depending on the size of the elevator.

As explained above, according to this invention, a gauge block of an appropriate thickness can be removably fixed to the ruler surface of the ruler plate according to the size of the guide rail, so that the ruler surface and the piano wire for centering can be connected. We have developed a centering device for guide rails that allows you to freely adjust the distance, keep the position of the centering piano wire that serves as the installation standard constant, prevent work errors, and facilitate the standardization of equipment. It has the effect of being able to provide
