Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an elevator control cable steady rest guide device for preventing wire breakage accidents caused by swinging of the elevator control cable.

As shown in FIGS. 1 and 2, conventionally, the control cable 3
In order to prevent the duct 5 from jumping out from inside the duct 5 installed in the hoistway, (1) Attach folds 5A and 5B to the car 2 side of the duct 5 to prevent it from jumping out (Figure 1).

(2) Protectors 2A and 2B for preventing jumping out are provided at positions facing the duct 5 of the car 2 (FIG. 2).

(3) Without providing a steady rest for the control cable 3, the hoistway 4
Efforts have been made to minimize the protrusion of internal equipment and prevent the control cable 3 from getting caught.

However, since the control cable 3 moves as the elevator runs, various factors such as vibration of the car 2, wind pressure, operating characteristics of the elevator, twisting of the control cable 3 itself, and the quality of the control cable hanging work may affect the control cable 3. They interfere with each other, causing a phenomenon of popping out from the duct 5,
Once the control cable has protruded, it is difficult to fit it back into the duct 5, so it may be hung on equipment in the hoistway, or
Moreover, it may become caught between the protector 2 A t 2 B on the passenger car 2 side and the duct 5, causing a disconnection accident of the control cable 3.

An object of the present invention is to eliminate the above-mentioned drawbacks of the prior art and to ensure stable power supply to the passenger car.

The present invention provides a control cable guide device consisting of rotating bodies on three sides at positions corresponding to the upper and lower ducts of the passenger corner, and forms a space surrounding the control cable from all sides between the control cable guide device and the duct. This device has a function of preventing the control cable from flying out from the duct and storing the control cable that has flown out of the duct back into the duct. An embodiment of the present invention is shown in Figs. 3 to 6. This will be explained with a diagram.

As shown in FIG. 3, a control cable support is attached to the elevator shaft 2 suspended from the main rope 1 through the inside of the duct 5 attached to the shaft 4 from the lower part thereof and attached to the upper part of the shaft 4. A control cable 3 leading to a metal fitting (not shown) is connected.

The control cable steady rest guide device 6 of the present invention is attached to the upper and lower parts of the passenger seat 2 inside a duct 5 having a U-shaped cross section, with a gap of 1/2 or less of the diameter of the control cable 3 being secured.

The structure of the control cable steady rest guide device 6 is shown in Figures 4 and 5.
As shown in the figure, one side of the metal fitting 7 in the shape of a metal fitting is
are fastened together with bolts 8, and one end of a shaft 10 rotatably supporting a roller 9 is attached to both ends of the other side in the width direction of the duct.

Further, at the top of the other side, there is a shaft 11 that rotatably supports a roller 12 extending throughout the duct so as to be orthogonal to the roller 9.
The rollers are arranged in a U-shape as a whole.

When the rider and rider 2 are running, the control cable 3 inside the duct 5 swings and generates a force that tries to jump out of the duct 5, but it comes into contact with the rotating roller 9° 12 of the steady rest guide device 6 and is pushed back to its original position. .

Since the frictional force during contact is minute because the rotating rollers 9 and 12 rotate, the control cable 3 will not be damaged.

Furthermore, even if the control cable 3 jumps out of the duct 5 as shown in FIG. Since it rotates in the direction in which the cable 3 is wound up, the cable 3 can be housed in the duct 5 by its rotational force.

According to the present invention, it is possible to prevent the control cable from jumping out of the duct without damaging it, and also to store the control cable once it has jumped out in the duct, thereby preventing an accident in which the control cable is cut. I can do it.

In addition, in the present invention, the steady rest guide device is provided at the top and bottom of the passenger corner, so the control cable located between the passenger foot and the hoistway wall does not jump out of the duct and come into contact with the passenger corner. This prevents damage caused by contact between the control cable and the seat.

Claims (1)

[Claims] 1 Install a duct for the elevator control cable with a U-shaped cross section on the wall of the hoistway so that it opens toward the car side.
In an elevator in which a control cable is suspended along the inside of the duct, the control cable is surrounded on three sides in a U-shape planarly toward the wall surface of the hoistway at the upper and lower parts of the corner corresponding to the duct. The elevator control is characterized in that a rotating body is provided, and both U-shaped legs of the rotating body are positioned within the U-shaped opening of the duct so that they correspond to the U-shaped legs of the duct with a slight gap.
