JPH05254757A - Vibration damper for elevator controlling cable - Google Patents

Abstract

PURPOSE:To prevent a controlling cable from tangling on an equipment in a hoistway and from giving an influence to running of a riding cage due to the swing of the controlling cable caused by lifting of the riding cage, an earthquake or wind, in an elevator. CONSTITUTION:By a controlling cable 3 of mounting or mixing a magnetic metal in the peripheral coating and by a magnet plate 10 set up in a hoistway, the controlling cable 3 is fixed to prevent deflection. Thus by preventing the deflection of the controlling cable, running of a riding cage can be stably attained without also tangling on an equipment in the hoistway.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control cable for an elevator, and more particularly, to a sway of the control cable for an elevator caused by an elevator car or an earthquake, which is attracted and fixed to a wall by a magnet plate attached to the side surface. , Relates to a vibration damping device for preventing shake.

2. Description of the Related Art In an elevator, cables such as control signal lines and power lines are provided between a car that moves up and down in a hoistway and a control panel in a machine room by an elevator control cable. In the hoistway, this elevator control cable is supported at both ends by the car side and the control panel side, and hangs down by its own weight. For this reason, the car easily shakes up and down, earthquakes, wind, etc., and collides with the walls of the hoistway, which affects the running of the car and the entanglement of cables.
It was one factor that caused phenomena such as disconnection. This phenomenon becomes even more serious in skyscrapers, which becomes a problem.

As a publicly known example for solving the above problem, there is JP-A-3-13478, which is a rope in which a cable duct is installed in the vertical direction of the hoistway wall and the hoistway wall and the car are connected. The suspension of the control cable is suspended by the car and the lower end of the control cable, which restrains the horizontal movement of the control cable and distributes the control cable between the car side and the hoistway wall side. It is something to try.

[0004]

As described above, in the prior art, in addition to the weight of the control cable in the car, the weight of the guide machine connected to the wire rope and the guide machine travels in the cable duct. The load of time increases, and the load increases as the car rises. Also, if the guide does not go up and down smoothly, it will have a great impact on the car running.If the guide does not go up and down smoothly even when it goes down, the control cable will get caught in the guide, causing slack and disconnection. ,
There was a risk of collision between the guide and the car.

According to the present invention, since the control cable is closely attached to the side surface of the hoistway from the beginning and the wiring is attached, the portion where the cable is in contact with the side surface is fixed by the magnet plate already attached to the side surface of the hoistway to prevent runout. be able to. In addition, since there is no mechanical part such as a guide that travels in the cable duct, and the cable moves without obstructing the movement of the cable, the risk of catching or disconnection is reduced. Further, since there is no mechanical device, it is superior to the conventional technique in workability such as assembly and maintenance.

[0006]

[Means for Solving the Problems] In order to achieve the purpose,
A cable in which a magnetic metal is attached to the outer circumference of the control cable or a cable in which a magnetic material is mixed in the outer circumference is attached to the side surface of the hoistway. In addition, a magnet plate is installed on the side of the hoistway in the passage of the control cable, so that the control cable that is in close contact with the hoistway wall is always attracted and fixed.

[0007]

In the vibration control device for an elevator control cable according to the present invention, since the control cable has magnetic metal attached to or mixed with the outer peripheral coating, the control cable is attracted by the magnet plate installed in the hoistway. It is fixed to the side. Therefore, the horizontal movement is restricted. Further, since there is no duct or guide that obstructs the running of the cable, the cable is not caught, and it is possible to reliably prevent the control cable from swinging or sagging.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIG. FIG. 1 is a side view showing an overall configuration example of an elevator having a vibration damping device for an elevator control cable according to an embodiment of the present invention.

In FIG. 1, 4 is a hoisting machine driven by an electric motor, 5 is a deflector wheel for moving the lifting position of the counterweight 6 away from the lifting position of the car 1, and 7 is a balance located at the bottom of the hoistway 9. Vehicles 2 are main ropes that connect the car 1 and the counterweight 6 via the hoist 4, and 3 is a magnetic material on the outer circumference coating that performs signal transmission and power supply between the car 1 and the control panel in the machine room. Control cable mixed with 10 is hoistway 9
It is a magnet plate attached to the side of.

Here, the control cable 3 is wired and attached so as to be in close contact with the side wall of the hoistway 9. Further, on the wall where the control cables 3 are in close contact with each other, the car 1 is installed, and the magnet plate 10 is installed at a length equal to or longer than the length at which the control cables 3 on the uppermost floor and the lowermost floor contact the wall. When the car 1 rises, the control cable 3 fixed to the side surface of the hoistway is pulled and gradually moves away from the side surface of the hoistway. When the car 1 descends, the control cable 3 moves to the hoistway. When pushed to the side surface, it is attracted and fixed by the magnet plate 10, and the portion of the control cable 3 that is in contact with the side surface of the hoistway is fixed at all times to prevent the cable from swinging.

[0011]

The elevator control cable damping device of the present invention has the outer periphery of the control cable made of a magnetic material, so that the control cable is attracted and fixed by the magnet plate installed on the side surface of the hoistway, and both ends of the control cable are secured. By fixing the other end of what was shaken with, it is possible to prevent shake,
Since it is not a mechanical device, it is easy to assemble and maintain, and it can prevent entanglement with equipment, prevent disconnection accidents of control cables, and improve safety.
