Description

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

First, based on Figures 1 and 2, for example,
The elevator guide rail centering device shown in No. 151267 will be explained.

In the figure, 1 is an elevator hoistway, 2 is a hoistway wall for forming the elevator hoistway 1, and 3, 3'
1 is a rail bracket fixed to the hoistway wall 2 with anchor bolts, 4 and 4' are guide rails attached to the rail bracket 3, and 5 and 5' are rails stretched between the upper and lower templates of the hoistway. This is piano wire for centering. To center the guide rail, a centering jig as shown in FIG. 2 is used. 6 is a main rod of the centering device, 7 is a level provided at the center of the main rod 6, and 8 is a ruler plate fixed to both ends of the main rod 6 with bolts 9. This ruler plate 8 has stoppers 8a, 8a' that set the distance between the guide rails 4, 4' by abutting the rail surfaces of the guide rails 4, 4', and the inclination between the guide rails 4, 4'. ruler surfaces 8b, 8b' for regulating the piano wires 5, 5', gauge notches 8c, 8c' that match the piano wires 5, 5', and markings 8d for positioning the piano wires 5, 5' provided around these notches. , 8d'. In addition, 10 and 10' are the guide rails 4,
This is a mounting mechanism for temporarily attaching it to arm 1.
1, an engaging member 12, and a threaded rod/nut 13.

To center the guide rail, first select the main rod 6 of the required length according to the spacing between the elevator guide rails, tighten and fix the ruler plate 8 to both ends of the main rod 6 with bolts 9, and then attach the ruler plate 8 to both ends of the main rod 6. The assembly of the guide rail centering device is completed by checking the dimensions between the stoppers 8a, 8a' of the plates 8, 8' and the distance between the gauge notch positioning markings.

On the other hand, the rail bracket 3 is fixed to the hoistway wall 2 with anchor bolts or the like. Then, with the guide rails 4, 4' temporarily fixed to the rail bracket 3, the ruler surfaces 8b, 8b' are temporarily applied to the side surfaces of the guide rails 4, 4'. After that, the mounting mechanisms 10, 10' are attached to the flanges of the guide rails 4, 4' by tightening the mounting nuts 13, and the top surfaces of the guide rails 4, 4' are brought into contact with the stoppers 8a, 8a', and the side surfaces of the rails are Adjust to ensure alignment with the ruler surfaces 8b, 8b', and at the same time check the level using the spirit level 7. In this state, the positioning markings 8d and 8d around the gauge notches 8c and 8c',
The centering piano wire 5 is aligned and positioned at 8d', then the guide rails 4, 4' are securely fixed to the rail bracket 3, and then the rail centering device is removed. However, since the size of the car varies depending on the type of elevator, the dimensions between the guide rails vary, and therefore a large number of main rods 6 for replacement must be prepared. In addition, the assembly and checking required careful attention and the work was difficult. Another disadvantage was that it required two people to center the left and right guide rails at the same time.

This invention solves the above-mentioned drawbacks and provides a guide rail centering device that uses two piano wires to center the guide rails of an elevator regardless of the mutual spacing of the guide rails depending on the type of elevator. This is what I am trying to do.

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

In the figure, the same reference numerals as in Figure 2 indicate the same (or equivalent) parts, 14 is a boomerang-shaped ruler plate with a groove for mounting the guide rail in the center, and 14a is for positioning the top surface of the guide rail 4. Stopper surface, 14
b is a ruler surface that regulates the inclination. 14c, 14
C' is a notch for a gauge that is fitted to the piano wire 5, and markings 14d for positioning the piano wire 5 are provided in these notches. The process up to the temporary fixing of the guide rails is the same as the conventional method, but two piano wires 5 are stretched on each guide rail 4 to serve as a reference for installation. Then, the ruler plate 14 is
It is fixed to the guide rail by a mounting mechanism 10 attached to this. Center the guide rail using two piano wires 5, 5' and the corresponding notch groove 1.
By matching the markings 4c and 14c', the guide rail interval and the twist of the guide rail can be detected. That is, by using two piano wires, the distance between the guide rails and the mutual twisting state can be adjusted and centering can be performed, so it is not necessary to arrange and assemble the main rod depending on the type of elevator. Therefore, the centering work of the elevator guide rail becomes easier and the installation time is reduced.

As explained above, this invention is a guide rail centering device in which two notched grooves are provided on a ruler plate and two piano wires are used to detect the mutual spacing and mutual twist state of the guide rails. This eliminates the need for arranging and assembling main rods regardless of the elevator guide rail spacing, and
Centering of the guide rail can be performed by one person without damaging the guide rail, and material costs and installation time can be reduced.
