Description

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

First, a conventional elevator hoistway system will be explained with reference to FIGS. 1 and 2.

In the figure, 1 is an elevator hoistway, 2 is a fixed body consisting of a car rail erected on the hoistway, 2' is a fixed body consisting of a counterweight rail erected in the hoistway 1, and 3 is a fixed body. 3' is a counterweight that is guided by the fixed body 2' and goes up and down; 4 is a governor for car 3; 4' is a governor for counterweight 3'; 5 is a governor for car 3. A governor rope for a car 3 (hereinafter simply referred to as a car rope) that is wrapped around a car 3 and has an endless shape and is connected to the car 3 on one side. Reference numeral 5' denotes a governor rope for the counterweight 3' (hereinafter simply referred to as "weight rope") which is wound around the governor 4' for the counterweight 3' and has an endless shape and is connected to the counterweight 3' on one side. 6 is a support arm whose one end is fastened to the fixed body 2 and is extended; 7 is a steady rest supported by the other end of which the other end of the car rope 5 is loosely inserted; and 6' is the support arm 6.
This is a support arm which is similar to the above and is provided on the fixed body 2' and supports a steady rest 7' through which the other side of the weight rope 5' is loosely inserted.

That is, the other sides of the car and the weight ropes 5, 5' are held by the steady rests 7, 7', respectively, and unnecessary oscillations are suppressed. However, the connection side of the car and the weight ropes 5 and 5' between the car 3 and the counterweight 3' is abnormally shaken due to earthquakes, typhoons, etc., and the support arms 6 and 6' are moved as shown by the broken lines in Figure 2. From the tip,
There was a problem in that the governors 4 and 4' got stuck between this and the hoistway 1, restricting their movement and causing the governors 4 and 4' to malfunction.

This invention solves the above-mentioned drawbacks and aims to provide an elevator hoistway system that prevents accidents caused by abnormal oscillations on the connection side of the governor rope.

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

In the figure, the same reference numerals as in FIGS. 1 and 2 indicate corresponding parts, and 6 is a support whose one end is fixed to the fixed body 2 and is extended and bent, and the other end is fixed to the fixed body 2'.
are arranged at appropriate intervals in the height direction of the hoistway 1,
7 and 7' are steady rests supported by the support 6, respectively.

That is, when the car and the weight ropes 5, 5' are abnormally shaken, since the connecting side is provided with the integrated support 6, the connecting side does not get between the car and the hoistway 1, and the movement is not restricted. Therefore, it is possible to prevent accidents caused by abnormal oscillations of the car and the weight ropes 5, 5'.

In addition, each support member 6 has the function of preventing rope entanglement with respect to each of the two types of ropes 5 and 5', and also serves as a rope entanglement prevention function for each of the two types of ropes 5 and 5'.
Since it is only fixed in two places, the installation work is also extremely simplified. In other words,
Providing independent supports for each of the two ropes 5, 5' will increase the number of parts, and of course each support will have to be supported between the fixed body and the hoistway wall. Therefore, the work becomes complicated, but this invention can prevent such a problem.

Furthermore, the support 6 is constructed and fixed to the fixed bodies 2, 2', which is very convenient. In other words, the structure of a building's hoistway is not the same from the top to the bottom, but the lower the layer, the more weight it has to support, so the lower layer has a stronger structure, the size of the beams installed horizontally is larger, and the wall thickness is also larger. Generally speaking, it is becoming more familiar. Therefore, when trying to fix the support to a wall, it is necessary to consider the position of the mounting brackets according to the wall structure, which differs depending on the level, which requires extremely complicated work. In the design, the support body 6 is fixed to the fixed bodies 2, 2' such as guide rails that do not change the structure, so there is no need for complicated work such as considering the installation position during installation, which simplifies the process. This enables the installation work to be carried out in a timely manner.

In this embodiment, the same effect can be obtained even if the support body 6 is composed of two bodies, one end of which is fastened to each other and the other end of which is fixed to the fixed bodies 2 and 2', respectively. That is clear.

As explained above, this invention consists of a rope in which the non-connected ends of the governor ropes for the car and counterweight are loosely inserted through a support whose both ends are fixed to a fixed body in the hoistway near the car and counterweight, respectively. Since the first and second steady rests are supported, when the connecting side of the rope is abnormally shaken, the rope does not get stuck between the support and the hoistway and the movement is restricted.
The object of the present invention is to realize an elevator hoistway device that can prevent elevator accidents caused by abnormal oscillation of the rope and can facilitate installation work.
