Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an elevator cable, and in particular, it is an object of the present invention to provide an elevator cable with a small wind blowing area.

Elevator cable (hereinafter referred to as
- called ``pull'' or simply ``cable''. The structure of conventional cables ( ) generally uses multiple cables such as control cables and signal cables that are grouped according to function into a single cable with a circular cross section.

However, circular cross-section aggregate cables tend to twist easily and swing easily due to their relative light weight, so when such cables are used, the cables also move up and down as the elevator car moves up and down. It is a thing,
If the cable is exposed to wind pressure while moving, it will sway laterally,
There is a risk that the cable may become tangled, and therefore, if the degree of lateral vibration becomes large, the cable may become caught on external structures, etc., causing accidents such as damage or breakage of the cable. It was.

Therefore, an object of the present invention is to eliminate the drawbacks in the prior art as described above, and to eliminate the problems caused by vibrations caused by wind pressure caused by elms during overnight driving, interference between various cables and ropes, and between fixed objects such as buildings. It is an object of the present invention to provide a new elevator cable that can prevent the occurrence of factors that cause cable damage or breakage.

The gist of the present invention is to reduce the substantial wind-blown area of the elevator cable and to provide sufficient resistance against twisting action.Hereinafter, embodiments of the present invention will be described with reference to the drawings. .

An elevator cable according to an embodiment of the present invention.

As shown in FIGS. 1 and 2, signal cables 20 having signal lines 1 for overnight operation are arranged side by side on both sides at regular intervals and with their axes located on the same plane. The elm has a control cable 4 having a single control line 6, and a bridge part 5 is interposed between the signal cable 2 and the control cable 4 so that a flat cable shape is formed as a whole. be integrated.

A tension member is provided in the intermediate portion of the bridge portion 5, preferably in a portion close to the control cable 4 located on the outside, to prevent twisting during movement of the cable and to receive tension due to vertical movement. 116 are provided integrally so as to be juxtaposed. The bridging portion 5 is also arranged such that slits or windows 7 are opened at appropriate intervals in the area where the reinforcing wire 6 is not provided.

The elevator cable according to the present invention configured as described above is formed into a U-shape or a 5-shape with slack so as to connect between the lower part of the elevator car and the junction box disposed at an intermediate position of the cage kite 8 rail. It is provided in a shape. At this time, the flat cables are installed in such a position that the same sides of the cables always face each other.

In this way, the elm cable according to the present invention integrates signal and control cables into a flat plate shape, thereby preventing damage caused by interference between the cables and allowing them to be spaced apart. By having the reinforcing wire, it is possible to prevent the cable from twisting, and it is also possible to prevent the tension caused by overnight up-and-down running from affecting signal and control lines. Furthermore, by providing slits with the required area in the bridge section to reduce the airflow area per unit area of the cable and reducing air resistance, the cable's horizontal vibration due to wind pressure during driving is minimized. In addition, in the case of cables for outdoor or construction elevators, reinforcing wires prevent twisting and slits reduce the area of wind blowing, so even when strong winds blow directly onto the cables, the elevators can be easily operated. This is sufficient to ensure safe driving.

Here, the signal and control cables and bridge parts in the above-mentioned embodiments and illustrated elevator cables,
The arrangement positional relationship between the reinforcing wire and the slits provided in the bridge part, their number, and the assembly relationship are explained as one example, and various cables and reinforcing wires have a bridge part and are flat-shaped. It has a slit that is integrated into the cable of the configuration, has a defined slit in the bridge section to reduce the wind blowing area and maintain connection strength that can ensure the integrity of the cable, and prevents twisting of the cable and It is obvious that any arrangement and dimensions can be formed as long as reinforcing wires are provided so that the tension caused by running the elevator does not have an adverse effect on the signal and control lines, and these do not fall within the scope of the present invention. This is a matter that should be followed.
