Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a hanging fixture for a cable drum that is easy to hook and secure.

[0002]

[Prior art and its problems]

 Conventionally, loading and unloading of a cable drum is carried out by passing a shaft S through a shaft hole H of a cable drum D as shown in FIG. 4, hooking a hook F on the shaft S, and using a hanging wire 5 by a crane or the like. It's hanging.

However, with this means, it is necessary to pass the shaft S through the shaft hole H of the cable drum D, and this work is troublesome, and sometimes the operator slips his or her hand to drop the shaft S. Yes, it is dangerous. Further, since both the shaft S and the hook F are usually made of a steel material, there is a danger of slippage between them.

In view of the above, it is an object of the present invention to provide a hanging fitting for a cable drum which can be easily and safely hooked and mounted.

[0005]

[Means for Solving the Problems]

 In order to solve the above problems, according to the present invention, a yoke inserted into a shaft hole of a cable drum, a hook arm extending from an inner end of the yoke to a lower part of the shaft hole, and an upper end from an outer end of the yoke are provided. And a hanging arm to which a hanging wire is connected, and the hanging arm is thick enough to pass through the shaft hole, and when the yoke is applied to the upper surface of the shaft hole, the lower edge of the shaft hole extends from the inner surface of the cable drum collar. It has a length that extends downward, and the upper and outer surfaces from the yoke to the hanging arm are set so that the yoke contacts the lower surface of the shaft hole and the yoke rotates around the contact point so that the hanging arm passes through the shaft hole. It has been configured.

[0006]

The hanging metal fitting according to the present invention configured as described above is inserted into the shaft hole of the cable drum from the hanging arm side, and when the yoke hits the brim, the yoke is applied to the lower surface of the shaft hole to move upward. When turned, the upper outer surface from the yoke to the hanging arm passes through the shaft hole, and the yoke enters the shaft hole.

In this state, the suspension wire is connected to the suspension arm, or is connected in advance, and the suspension wire is pulled up by a crane or the like. Then, since the hanging arm extends to the lower side of the shaft hole and has a required length, the hanging arm comes into contact with the inner surface of the cable drum brim, while the upper surface of the yoke comes into contact with the upper surface of the shaft hole. It is fixed in the hole. Therefore, the cable drum is hoisted via the hoisting metal fitting.

[0008]

【Example】

 As shown in FIG. 1, the hanging metal fitting Q of this embodiment has a yoke 1 portion which is inserted through the shaft hole H of the cable drum D in the center, and a hanging arm 2 extending downward is integrally provided at the inner end thereof. At the outer end, a hanging arm 3 extending upward is integrally provided, and the hanging arm 2 has a thickness that allows it to pass through the shaft hole H, and has a length that makes contact with the inner surface of the cable drum collar D ′ during the following lifting. There is.

The upper outer surface 4 from the yoke 1 to the hanging arm 2 becomes a rounded surface, and the metal fitting Q is inserted into the shaft hole H of the cable drum D from the hanging arm 2 side as shown in FIG. The hook 1 is brought into contact with the lower surface of the shaft hole H, and the yoke 1 is rotated around the contact point P so that the hanging arm 2 can pass through the shaft hole H.

An insertion hole 6 is formed at the end of the suspension arm 3, and a suspension wire 5 from a crane or the like is inserted through the hole 6 and fixed in an annular shape. A hook may be provided at the end of the hanging wire 5 and the hook may be inserted into the insertion hole 6 to connect the hanging wire 5 to the hanging metal fitting Q 1.

In order to suspend the cable drum D by the suspending metal fitting Q, first, as shown in FIG. 2A, first, the yoke 1 is inserted into the shaft hole H of the cable drum D, and the yoke 1 becomes the collar D ′. When the yoke 1 hits the lower surface of the shaft hole H and is rotated upward, the upper outer surface 4 from the yoke 1 to the hanging arm 2 passes through the shaft hole H as shown in FIGS. The yoke 1 enters the shaft hole H. At this time, the hanging wire 5 is connected to the hanging arm 3, and the wire from the crane is hung on the hanging ring 7.

When the suspension wire 5 is pulled up in this state, the hanging arm 2 extends downwardly of the shaft hole H and has a required length. Therefore, as shown by the solid line to the chain line in FIG. 1, the inner surface of the cable drum collar D ′ is shown. On the other hand, the upper surface of the yoke 1 abuts on the upper surface of the shaft hole H, and the hanging metal fitting Q is fixed in the shaft hole H by both of these abutments. Therefore, the cable drum D is hung up via the hanging metal fitting Q. On the other hand, when the lifting force stops working, the rotational force in the chain line direction disappears, and the hanging metal fitting Q becomes free in the shaft hole H. Then, since the suspension arm 3 side is heavy, the reverse action of the above action is naturally performed by its own weight (FIG. 2c → b → a), and easily disengages from the shaft hole H.

[0013]

[Effect of the device]

 Since the present invention is configured as described above, the suspension wire can be easily and reliably locked in the shaft hole of the cable drum. The locked state is more secure because the weight of the cable drum is more reliable.
