[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an elevator guide rail centering device.

[Conventional technology]

Recently, as shown in Japanese Unexamined Patent Publication No. 55-48182, a method of installing elevators has recently been developed, in which the floor of the elevator car is raised and lowered by a built-in traction machine, and the work is carried out on top of this floor. One proposal has been proposed in which a person installs the entrance/exit threshold, three-sided frame, wiring, piping, etc. As a guide rail centering device used in such an installation method, for example, one shown in Japanese Patent Application Laid-Open No. 127583/1983 has been proposed. An example will be explained based on the drawings.

Figures 3 to 5 are diagrams for explaining a conventional guide rail centering device, with Figure 3 being a plan view showing the overall configuration, and Figure 4 being an enlarged vertical sectional view taken along line A-A in Figure 3. , FIG. 5 is an enlarged plan view showing the main part configuration.

In FIG. 3, a guide rail centering device 2 is provided in the hoistway 1. As shown in FIG. The guide rail centering device 2 includes a main rod 3 extending across the hoistway 1, ruler plates 4 and 4a provided at both ends of the main rod 3, and contact portions 5 and 5a. , pressing parts 6, 6a, etc. ruler board 4,
4a engages with piano wires 7, 7a stretched vertically in the hoistway 1, and scribes lines 8, 8.
A is attached. The contact parts 5 and 5a are connected to the hoistway 1
The pressing portions 6, 6a contact the side surfaces 10 and end surfaces 11 of the guide rails 9, which are erected to face each other, and the side surfaces 10a and end surfaces 11a of the other guide rail 9a, respectively.
12a, and by tightening these bolts 12, 12a, the other side surface 13 of the guide rail 9a and the other side surface 13a of the guide rail 9a are pressed, respectively.

Guide rail centering device 2 configured in this way
In order to center the guide rails 9, 9a, first stretch the piano wires 7, 7a that will serve as the reference line for centering, and then This guide rail 9 is fixed to the guide rail centering device 2 by disposing it between the contact portion 5 and the pressing portion 6 and tightening the bolt 12, and similarly, the other guide rail 9a is also aligned with the guide rail centering device 2. Fixedly installed in device 2. Next, while holding the main rod 3, move the guide rail centering device 2, as shown in FIG. Align the marking line 8a on the board 4a with the piano wire 7a. In this state, fix the guide rails 9, 9a to the walls of the hoistway 1, loosen the bolts 12, 12a of the guide rail centering device 2, and remove the guide rail centering device 2 from the guide rails 9, 9a. It's summery.

[The problem that the idea aims to solve]

By the way, in the conventional guide rail centering device 2 as described above, this guide rail centering device 2
After fixing the guide rails 9 and 9a to the
When moving for alignment, as shown in FIG.
A force that creates the gap 15 acts on the principle of leverage. At this time, the friction force between the contact surface 16 of the contact section 5 and one side surface 10 of the guide rail 9 and between the pressing surface 17 of the pressing section 6 and the other side surface 13 of the guide rail 9 holds the guide rail 9. As a result, as shown in FIGS. 4 and 5, the stopper surface 18 of the contact portion 5 and the end surface 11 of the guide rail 9
A gap 15 is created between them. Therefore, there was a problem in that it was often necessary to loosen the bolts 12 and correct the installation of the guide rail 9.

The present invention was made in view of the actual situation in the prior art as described above, and its purpose is to prevent a gap from forming between the end surface of the guide rail and the stopper surface of the abutment portion that the guide rail abuts. An object of the present invention is to provide a guide rail centering device that can prevent this.

[Means to solve the problem]

In order to achieve this objective, the present invention provides a main rod that extends within the hoistway and crosses the hoistway, and a piano that extends vertically within the hoistway at both ends of the main rod. a ruler plate that engages with the line; a contact portion that abuts one side surface and an end surface of the guide rail erected along the guide rail; and a pressing portion that presses the other side surface of the guide rail. In the guide rail centering device, holding means are provided at both ends of the main rod to hold the guide rail in a state in which the end surface of the guide rail is in contact with the contact portion.

[Effect]

Since the present invention is configured as described above, the guide rail is held by the holding means provided at both ends of the main rod in a state in which the end surface of the guide rail is in contact with the contact portion. This results in
It is possible to prevent a gap from forming between the end surface of the guide rail and the stopper surface of the abutment portion with which the guide rail abuts.

〔Example〕

Hereinafter, the guide rail centering device of the present invention will be explained based on the drawings.

Figures 1 and 2 are diagrams illustrating an embodiment of the guide rail centering device of the present invention. Figure 1 is a plan view showing the overall configuration, and Figure 2 is an enlarged plan view showing the main part configuration. be. Note that in FIGS. 1 and 2, parts equivalent to those shown in FIGS. 3 to 5 described above are given the same reference numerals, and explanations thereof will be omitted.

A guide rail centering device 20 is provided within the hoistway 1 shown in FIG. At both ends of the main rod 3 of this guide rail centering device 20, holding means consisting of hook-shaped bolts 21, 21a, guides 22, 22a, nuts 23, 23a, etc. are provided, respectively. A guide 22 of one holding means of the guide rail centering device 20 shown in FIG. 2 is fixed to the ruler plate 4, and a hook-shaped bolt 21 is inserted into a hole 24 passing through the guide 22. The head 25 of this hook-shaped bolt 21 engages with the back surface 26 of the guide rail 9, while the nut 23 is screwed into the threaded portion 27. By tightening this nut 23, the head 25 of the hook-shaped bolt 21 is moved into the guide 22.
draw to. At this time, since the head 25 of the hook-shaped bolt 21 is engaged with the back surface 26 of the guide rail 9, the guide rail 9 is brought into a state in which the end surface 11 of the guide rail 9 is in contact with the stopper surface 18 of the contact portion 5. is retained. The same applies to the other holding means.

In this embodiment, in order to center the guide rails 9, 9a, first stretch the piano wires 7, 7a, which will serve as reference lines for positioning, and then use the guide rail centering device. The side surface 10 and end surface 11 of one guide rail 9 are brought into contact with one abutment section 5 of the guide rail 20, and the other side surface 13 is pressed by the pressing section 6 to tighten the bolt 12. Also, by engaging the head 25 of the hook-shaped bolt 21 with the back surface 26 of the guide rail 9 and tightening the nut 23, the guide rail is brought into a state in which the end surface 11 abuts against the stopper surface 18 of the contact portion 5. 9 is retained. After fixing the guide rail 9 to one end of the guide rail centering device 20 in this way, similarly,
The other guide rail 9a is fixed to the other end of the guide rail centering device 20. Next, main rod 3
As shown in FIG. 1, move the guide rail centering device 20 while grasping the

Match. In this state, the guide rails 9 and 9a are each fixed to the wall of the hoistway 1, and the bolts 12 and 12a and nuts 2 of the guide rail centering device 20 are fixed.
3, 23a to remove the guide rail centering device 20 from the guide rails 9, 9a.

In the embodiment configured in this way, it is possible to prevent a gap from forming between the end surface 11 of the guide rail 9 and the stopper surface 18 of the contact portion 5 with which the guide rail 9 comes into contact.

[Effect of idea]

Since the present invention is configured as described above, it is possible to prevent a gap from forming between the end surface of the guide rail and the stopper surface of the abutment portion with which the guide rail abuts. Therefore, the guide rail can be held securely during centering work, and there is no need to modify the installation of the guide rail.
Further, even when the length of the guide rail is large, there is an effect that the guide rail can be easily centered without increasing the size of the abutting part or the pressing part of the guide rail centering device.
