Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cable grip used for pulling, suspending, fixing, etc. cables.

Cable grips made of cylindrical braided steel wire are widely used.

When pulling a cable with this type of cable grip, the tightening force is concentrated on the tip of the cable inserted into the cable grip, which can cause damage to the tip of the cable, which has become a problem.

Furthermore, conventional cable grips can only be used to pull or suspend cables that have a circular cross section.

In addition, elevators have been widely adopted as buildings become taller in recent years, but there is no good support or suspension structure for the cables that transmit signals from the cages, and the cables have a short service life and are difficult to maintain and inspect. There's a problem.

The object of the present invention is to provide a new cable grip which can overcome all of the above-mentioned problems.

In order to achieve the above object, the cable grip according to the present invention includes a plurality of holding members each having an abdomen that is brought into close contact with the side surface of a cable, etc., and a pair of hanging ears provided on both sides of the abdomen; The holding members are arranged alternately and sequentially so as to face each other along the length direction around the outer periphery of the cable, etc., and the wire ropes are hung over the ears and braided, and the ends of the wire ropes are braided. It is configured to be able to tow or suspend cables, etc.

According to the above configuration, all of the above-mentioned problems are solved and the object of the present invention can be completely achieved.

Hereinafter, the present invention will be explained in more detail with reference to the drawings and the like.

1 to 4 show a cable grip according to the present invention used to support a flat cable.

FIG. 5 is a plan view and a side view showing an embodiment of the holding member of the cable grip.

The flat cable 1 that is the subject of this embodiment is the fourth
As shown in the figure, a large number of electric wires are coated with an elastic synthetic resin.

As shown in FIG. 4, the holding member 2 is composed of an abdominal section 2c that is brought into close contact with the side surface of the flat cable 1, and a pair of hooked ears 2a and 2b provided on both sides of the abdominal section 2c.

In this example, a large number of holding members of one type were prepared by processing a steel plate.

In addition, the inner diameter of the ears is large enough to easily accept a wire rope 3 that is thick enough to withstand suspension or towing.Once the object to be suspended is determined, the thickness of the wire rope 3 is determined, and the size of the inner diameter is determined. It will be done. The procedure for suspending the flat cable 1 using these holding members and the wire rope 3 will be explained.

In the suspended state shown in Figs. 1 to 4, from the lowest holding member 2-1, 2-2...2-n, the abdominal part of each holding member is c, and the ear part is a, Let us add the subscript b.

Holding members are arranged alternately on each side of the flat cable 1 so that the intermediate portion 3a of the wire rope 3 appears on the side opposite to the lowest holding member 2-1, the side in FIG. Then, hold down the wire rope with member 2
-1 on the ears 2-1a and 2-1b, and then on the ears 2-2a and 2-2b on the opposite pressing member 2-2. Braid it in this way, hang it over the ears 2-na, 2-nb of the uppermost presser member 2-n, and tie it with the fastener 4 on the opposite side of the uppermost presser member 2-n, the side shown in Figure 1. do.

By fixing the wire rope part that should be located above the fastener 4 to the fixed part or the traction part,
A suspended or towed state is formed.

In this state, the gravitational force applied to the wire rope 3 presses the abdomen of each cable grip and the flat cable, forming a strong bond between them.

The spacing and number of the holding members are determined depending on the weight of the cable to be suspended, and care is taken so that the load received by each holding member is uniform.

FIG. 6 is a front view and a side view showing a state in which a cable having a circular cross section is supported using another cable grip according to the present invention.

The inner surface of the abdominal part 5 of the holding metal fitting for a cable having a circular cross section is formed into a cylindrical surface so as to closely fit the outer shape of the cable.

The knitting procedure is the same as described above.

As explained above, since the cable grip according to the present invention uses a large number of holding members, each part of the cable can be held approximately equally by adjusting the number and arrangement of the holding members. This prevents concentration of force on one part of the body.

Further, since the holding member can be shaped to match the shape of the cable, etc., it can be applied to cables of any cross-sectional shape.

Further, since it is sufficient to just hang the wire rope over the ears of the holding member and weave it, the work is simple and does not require any skill.

Similarly, since it is easy to remove the cable from the cable grip, maintenance, inspection, replacement, etc. are also extremely easy.

Therefore, by using the cable grip according to the present invention, it becomes possible to suspend or tow cables with shapes that were previously considered impossible, as well as cables with limited length due to their increased weight.

Various modifications can be made to the embodiments described above within the scope of the present invention.

The holding member is not limited to a steel plate, but may be a molded product made of resin if there is no problem in terms of strength.

It is also possible to form a shape in which one of the ears is a hole, and a wire rope is previously inserted through one and then braided through the other.
