Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an elevator cable support device for an elevator.

In order to supply lighting and signals from the machine room control panel to the elevator car, metal ducts are used for the fixed wiring in the hoistway, and elevator cables are used for the moving parts. This conventional wiring method will be specifically explained with reference to FIGS. 1 and 2. In the figure, a control panel 1 for controlling the entire elevator, a hoisting machine 5 for driving a car 2 and a counterweight 3 via a rope 4 are installed in the machine room of the elevator. The wiring to the car 2 is connected from the control panel 1 to the metal duct 6.
An electric wire 7 is inserted into the hoistway and wired to a junction box 8 provided in the middle of the hoistway, and connected to the elevator cable 10 via a terminal block 9 inside the junction box 8.
This elevator cable 10 is connected to the junction box 8
The operation panel 1 inside the car 2 is hit to the hit part 12 at the bottom of the car 2 via the support part 11 at the bottom of the car 2.
It is wired to 3rd grade. Therefore, metal duct 6, electric wire 7, junction box 8, elevator cable 10
The cost is high due to the use of a variety of materials and supplies, and the elevator installation worker must connect the electric wire 7 and the elevator cable 10 to the terminal block 9 of the junction box 8 in a dangerous place with poor footing in the middle of the hoistway. It won't happen. In addition, in recent years, elevator hoistways have become narrower due to improvements in construction technology and cost considerations, and the distance between the car 2 and the hoistway wall has become very narrow, making wiring difficult because the connection box 8 cannot be made thicker. There were many problems.

In view of the above points, the present invention has been developed by wiring a single elevator cable directly from the control panel to the car, providing a cable support device at the top of the hoistway, and connecting the cable holders to the middle of the hoistway with a wire. However, it is an object of the present invention to provide an elevator cable support device that prevents shaking by fixing the wire and the elevator cable.

An embodiment of the present invention will be described below with reference to FIGS. 3 and 4.

A plurality of elevator cables 1 each having one end connected to a control panel 1 installed in an elevator machine room.
0 is hooked in a U-shape to a cable support device 14 provided at the top of the hoistway and is attached to a cable clip 15.
Supported by This cable support device 14 includes an arm 18 whose one end is fixed to a guide rail 16 for guiding the car 2 with a rail clip 17, a shaft 19 integrated with this arm 18, and a shaft 19 at its tip attached to the shaft wall. The load is supported by a fixed shaft receiver 20. A protective rubber plate 21 is wrapped around the shaft 19 to prevent the elevator cable 10 from being damaged. Next, a cable presser 24 is installed to fix the elevator cable 10 using a presser arm 22 and a presser foot 23, which are fixed to the guide rail 16 with a rail clip 17, at a position immediately below the cable support device 14 and in the middle of the hoistway. The cable retainers 24 are connected by a wire 25.
And this elevator cable 10 and wire 25
After each wire is fixed at a constant interval using an insulating lock 26 or the like, it is wired to the car 2.

In the above configuration, the load on the elevator cable is transferred to the cable support device at the top of the hoistway where the cable support device and the car do not come into contact even when the car moves up and down in the hoistway and goes to the top floor.
Since it is fixed in a letter shape, there is no problem even if the distance between the hoistway wall and the car is narrow. In addition, the portion above the middle of the hoistway other than the U-shaped part where the elevator goes up and down is fixed to the cable retainer and wire with an insulock, so it is safe and will not shake significantly even in the event of an earthquake.

As mentioned above, the elevator cable is routed directly from the control panel to the car, and the load of the elevator cable is supported at the top of the hoistway where the car is not, and it is fixed with cable holders and wires up to the middle of the hoistway. Because of this, the elevator cave does not shake significantly even if there is vibration up and down the car or an earthquake. Furthermore, since there is no need for metal ducts or connection boxes as in the past, the elevator installation work is not only safe and easy, but also greatly reduces cost.

In addition, in the above-mentioned FIG. 3, the cable retainer is provided in two places, the lower part of the cable support device and the position corresponding to the middle part of the hoistway, but as shown in FIG. A similar effect can be obtained by fixing . By doing this, the cable holder only needs to be placed in the middle part, so that a greater effect can be obtained.
