Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an elevator, and more particularly to an elevator in which a car and a guide rail of a counterweight can be integrated.

[Conventional technology]

A conventional elevator will be explained with reference to FIGS. 6 to 8.

In the figure, 1 is an elevator car, 2 is a car frame that supports the car 1, and the car frame 2 has an upper beam 2a.

It is composed of a lower beam 2b and a vertical column 2C. 3 is lift S
A car guide rail (not shown) is vertically installed inside the car, and the car 1 is supported on this guide rail 3 via an idler (not shown) so as to be able to rise and fall. Further, 4 is a counterweight, and 5 is a guide rail that guides the counterweight 4 in a vertically movable manner.

6 is a hoisting machine installed in a machine room (not shown) at the top of the hoistway, 7 is a sheave rotated by the hoisting machine, and 8 is a deflection wheel. A rope 9 is wound around the rope 9, and one hanging end thereof is connected to the upper beam 2a of the basket frame 2, and the other hanging end is connected to the counterweight 4.

In the elevator configured as described above, when the hoist 6 is driven and the sheave 7 is rotated in the forward or reverse direction, the rope 9 wound around the sheave 7 and the deflection sheave 8 is run. The car 1 and the counterweight 4 connected to both ends thereof are raised and lowered in a hanging manner along their respective guide rails 3.5.

[Problem that the invention seeks to solve]

In the conventional elevator as described above, four pairs of guide rails 3 and 5 are required for car 1 and counterweight 2, so when installing the elevator, rail centering work must be performed for each car and weight rail. must be done,
Installing the rails not only requires complicated work, but also raises the cost of installing the elevator.

This invention was made to solve the above-mentioned conventional problems, and an object of the present invention is to provide an elevator in which the rail mounting and elevator installation are labor-saving.

[Means for solving problems]

In the elevator according to the present invention, the counterweight 69 is formed into a U-shape, and its both ends are extended to a position close to the car guide rail, and the weight guide rail is engaged with the extended ends so as to be able to move up and down. It is integrated with the car guide rail.

[For production]

In this invention, the guide rail for the weight 9 is integrated with the guide rail for the car, so that the guide rail for the weight can be installed by simply installing the guide rail for the car, which saves labor in installing the elevator. and realize cost reduction.

〔Example〕

Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIGS. 1 and 2 show an example of an elevator according to the present invention. In this figure, parts that are the same as those in the conventional FIGS. 6 to 8 are given the same reference numerals, and their explanation will be omitted, and the parts that are different from the conventional will be mainly described.

That is, the difference from the conventional method lies in the counterweight and the guide rail, as is clear from FIGS. 1 and 2. The counterweight 10 is formed into a U-shape corresponding to the rear surface 1a and both side surfaces 1b, 1b of the car 1, and has both end portions 10a,
It extends to a position close to the vertical column 2C of the 10g elevator car frame 2, and its tip is provided with engaging portions 11, 11 that are slidably engaged along a guide rail, which will be described later. This engaging portion 11 is composed of a guide shoe.

Reference numeral 12 denotes a guide rail body commonly used by the car 1 and the counterweight 10. This guide rail body 12 includes a guide rail 13 for the car and a guide rail 14 for the weight. The car guide rail 13 is formed to be longer than the weight guide rail 14, so that the car guide rail 13 is longer than the weight guide rail 14. The car 1 and the counterweight 10, which are raised and lowered, do not interfere with each other.

The car 1 is supported by the integrated car guide rail 14 via a guide shoe (not shown), and the counterweight 10 is supported by the engaging portion 11 on the weight guide rail 14. Additionally, a counterweight of 10 bapI
One end of a rope 9 wrapped around the I wheel 7 and the deflection wheel 8 is connected.

The elevator constructed as described above consists of a guide rail main body 12 in which a guide rail 13 for one car and a guide rail 14 for a weight are integrally molded, and these are arranged on both sides of the car 1. , basket 1 and counterweight 1
0, it is possible to reduce the number of guide rails from four to two, which halves the work required to center the rails from four to two when installing an elevator. As well as being able to do so, the car guide rail 13
and the depth direction (height direction) of the weight guide rail 14
dimensions can be managed at the factory, improving the precision of the guide rail. Furthermore, since the time required for rail installation is substantially halved, it becomes possible to save labor in installing the elevator and to reduce costs.

3 to 5 show other embodiments of the elevator of the present invention.

In this embodiment, a counterweight 10 and guide rails 13 and 14 for the car and the weight are formed in the same manner as in the case of FIG. 6A and 6B are provided respectively), and the rope rope 11f7 is rotated by each hoisting machine 6A and 6B, respectively.
A and 7B are positioned above both sides of car 1, and each sheave 7A,
One end of the robes 9A, 9B wrapped around the car 7B is connected to rope connecting members 16, 16 protruding from both sides of the lower part of the car 1, and the other end of the rope 9A, 9B is connected to both ends 10n, 10a of the counterweight 10. The cage 1 and the counterweight 10 are suspended at two locations on both sides.

In such a second embodiment, the same effects as in the first embodiment can be obtained, and by setting the car 1 and the counterweight 10 to two hanging positions on both sides, Since the hanging positions of the car and the counterweight are close to each other, the deflection wheel can be omitted.

In addition, by hanging from two places on both sides, the rope hanging position for the car 1 can be at the bottom of the car 1.
Accordingly, the vertical columns 2C and the upper beams 2a of the car frame 2 only need to be strong enough to support the guide shoe and steady rest, and the car frame 2,
This makes it possible to quantify the entirety of Bakago 1.

Although the second embodiment described above uses two hoisting machines, it is also possible to use one hoisting machine. in this case,
The sheaves 7A and 7B on both sides will be attached to a common hoist rotating shaft.

〔Effect of the invention〕

As described above, according to the present invention, the counterweight is formed into a U-shape, both ends of which are extended to a position close to the car guide rail, and the extended ends of the counterweight are engaged with the car guide rail so as to be able to move up and down. Since the guide rail is integrated with the car guide rail, it is possible to save labor in mounting the rail and installing the elevator.
