Abstract

PURPOSE:To prevent a current collector from its wire separation by providing a trolley wires for feeding power to a balance weight provided in an elevator tower, and providing the collector in the balance weight for absorbing this power, so that a space between the balance weight and the trolley wires can be accurately ensured. CONSTITUTION:Drive power for a lighting device 9, set up in a balance weight 2, is supplied from an elevator control panel 8 through a trolley wire 6a mounted on guide rails 5 provided in both sides of the balance weight 2, and a control signal is supplied through a trolley wire 6b. Power fed to the trolley wire 6a is supplied to a lighting device control panel 10 by a collector 7a provided in the balance weight 2, and the control signal fed to the trolley wire 6b is supplied to this control panel 10 by a collector 75, to control lighting and displaying the lighting device 9 by this control panel 10. By a power feeder thus obtained, fluctuation of a space between the balance weight 2 and the trolley wires 6a, 6b is almost not generated, and wire separation of the collectors 7a, 7b can be surely prevented.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator power feeding device having a structure in which electric power is transmitted to a suspension weight of an elevator from a trolley wire.

[0002]

2. Description of the Related Art Conventionally, as a method of supplying power from a suspension weight, there is Japanese Utility Model Laid-Open No. 4-53769 in which a trolley is installed in a tower for a linear motor elevator.

[0003]

It is difficult to secure a trolley wire laying place in the hoistway because each device, supporting metal fittings, etc. are arranged. Also, regarding trolley wire laying, the trolley wire and the current collector are kept constant. It was also difficult to set the distance, and there were problems of wire separation and noise due to bending of the trolley wire. It is an object of the present invention to provide an elevator power feeding device that uses a trolley wire installed linearly at a constant distance from a hanging weight without taking up space.

[0004]

In order to achieve the above object, the present invention installs the trolley wire separately on the guide rails on both sides of the hanging weight so that the trolley wire can be installed on the hanging weight without taking up space. The trolley wire can be installed at a certain distance from the electrons.

[0005]

Since the installed trolley wire is attached to the guide rails of the hanging weight, the distance between the current collector provided on the hanging weight and the trolley wire does not fluctuate, and separation of the current collector can be prevented.

Further, the rigidity of the trolley wire can be sufficiently ensured, and the trolley wire will not be broken when an earthquake occurs.

Even when the trolley wire is laid, it is not necessary to provide an in-column supporting mechanism for laying, and the laying is easy and inexpensive.

Even if the trolley wire is attached to the guide rail via a metal fitting, the same effect can be obtained.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is a side view showing the overall construction of an elevator having a power feeding device of the present invention, and FIG. 2 is a plan view of its hoistway. In FIG. 1, 1 is a car, 2 is a hanging weight, 3 is a rope, 4a and 4b are support pulleys, 5 is a hanging weight guide rail, 6a and 6b are trolley wires, 7
a and 7b are tandem current collectors installed on the counterweight, 8 is an elevator control panel, 9 is a lighting device that is turned on by the electric power received from the trolley wire, 10 is a control panel of the lighting device,
Reference numeral 11 is a car guide rail, and 12 is a hoistway.

The drive power of the lighting device 9 installed on the suspension weight 2 is supplied from the elevator control panel 8 to the trolley wire 6 attached to the guide rails 5 on both sides of the suspension weight 2.
It is supplied to a and its control signal is supplied to 6b.

The power supplied to the trolley wire 6a is collected by the collector 7.
It is supplied to the lighting device control panel 10 attached to the hanging weight 2 by a.

The signal supplied to the trolley wire 6b is supplied to the control panel 10 mounted on the suspension weight 2 by the current collector 7b.

The power and signals received by 7a and 7b are
The lighting device 9 is turned on and displayed via the control panel 10.

According to the present embodiment, since the trolley wires 6a and 6b are installed on the hanging weight guide rail 5, the space between the hanging weight 2 and the trolley wires 6a and 6b hardly changes. , Prevent disconnection of collectors 7a, 7b,
A reliable power supply is possible.

At the same time, a place for laying the trolley wires 6a and 6b is not particularly required.

[0017]

According to the elevator power feeding device of the present invention, since the trolley wire is installed on the hanging weight guide rail, the distance between the hanging weight and the trolley wire can be ensured with high precision, and therefore the separation of the current collector can be prevented. it can.

Since the trolley wire is provided on each of the right and left sides of the guide rail of the hanging weight, the trolley wire can be installed in a small space.
