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 steel wire woven into a cylindrical shape are widely used.

When pulling a cable with this type of cable grip, the tightening force concentrates on the tip of the cable inserted into the cable grip, causing damage to the tip of the cable, which is a problem.

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

In addition, elevators have become widely used 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, which means that the cables have a short service life and are not easy to maintain and inspect. There's a problem.

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

In order to achieve the above object, the cape (2) according to the present invention includes a plurality of holding members having an abdomen that is brought into close contact with the side surface of a cable, etc., and a pair of hooks provided on both sides of the abdomen; The receiver consists of a wire rope that is inserted into the ear, and the holding members are sequentially arranged around the outer periphery of the cable, etc., and the wire rope is woven around the ear so that the cable or the like can be pulled or suspended at the end of the wire rope. There is.

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 state in which a flat cable is supported using the cable grip according to the present invention.

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

As shown in FIG. 4, the flat cable 1 which is the object of this embodiment is made by covering a large number of electric wires with an elastic synthetic resin.

(3) The holding member 2 is attached to the flat cable 1 as shown in FIG.
A pair of hooks provided on both sides of the abdomen 2c are composed of ears 2a and 2b.

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 ear is large enough to easily receive a wire rope 3 having a thickness sufficient to withstand suspension or traction.
Once the subject of the pull-up is determined, the thickness of the wire rope 3 is determined.
The size of the inner diameter can be determined.

The procedure for suspending the flat cable 1 using these holding members and the wire rope 3 will be explained.

2-1 from the lowest pressing member in the suspended state shown in FIGS. 1 to 4. 2'-2...2-n, and suffixes a and b are attached to the C ears of the abdomen of each holding member.

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, the wire rope is hung on the ears 2-1a and 2-1b of the holding member 2-(4) (1), and then on the ears 2-2a and 2-2b of the holding member 2-2 on the opposite side. The ears 2-n of the uppermost pressing member 2-n are knitted in this way.
Na, 2-nb and bind with a fastener 4 on the opposite side of the uppermost holding member 2-n, the side shown in FIG.

By fixing the wire rope section to be located above the fastener 4 to a fixed part or a traction part, a suspended or traction condition is created.

In this state, the gravitational force applied to the wire row 13 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 inner side (5) of a 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, the cable grip according to the present invention is
By using a large number of pressing members, and by appropriately arranging the number and arrangement of the pressing members, each part of the cable can be pressed approximately equally, thereby preventing concentration of force on a part of the cable.

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, and other tasks are also extremely easy.

Therefore, by using the cable grip according to the present invention, it becomes possible to suspend or tow cables, etc. that have a uniform length due to the pull and weight of the cable (6), which was previously considered impossible. .

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.

Alternatively, one of the ears may have a hole, and a wire rope may be inserted through one of the ears beforehand and then braided on the other side.
