BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable drum made of wood or the like, and in the process of paying out a wound electric wire cable (hereinafter referred to as a cable), the end of the winding start of the cable is projected from the winding start opening. The present invention relates to a cable container in which a protruding cable end is housed in a housing portion on a side surface of a drum so as not to get in the way.

2. Description of the Related Art FIG. 4 shows an example of a conventional wooden drum.

In this figure, reference numeral 1 is a left and right wooden disk having a central shaft hole 2. A large number of wooden beams 3 are applied to the outer peripheries of the left and right disks 1 and fixed with nails or the like to form a cylindrical body 4.

A collar 5 made of a large-diameter wooden disk and having a shaft hole 2 in the center is applied to both ends of the body 4, and is fixed to the body 4 by means of screwing or the like. The cable 7 is wound from the winding start port 6 on the wooden body 4 thus constructed, and both ends of the small splits 9 are fixed to the outside of the collar 5 with nails or the like to protect the cable.

[0005]

In recent years, the amount of cable winding per drum has become long in order to improve the productivity of cables, and to reduce the costs of manufacturing, transportation, and inventory control. In other words, what used to be 200-500 m was 2000-30
It has become 00m.

When the length of the cable wound around one drum is increased, the following problems occur.

The first method is to hook the crane on the shaft hole of the drum or to put the shaft on the shaft hole to hook the shaft when handling the load of the packing drum, but the number of windings is large and the weight is large. Will damage the shaft hole.

The second point is that when the cable wound on the drum is fed while being cut to the required length at the construction site, the cable projects from the winding start port 6.

The reason is that the cable is tightly wound around the drum body at the time of shipment, but the wood constituting the drum is dried and shrunk due to the passage of time such as transportation and storage, and the drum body and the cable wound around it. There is a slight gap between and.

When a gap is generated in this way, the gap is accumulated according to the rotation of the drum due to the feeding of the cable, the accumulated length is concentrated at the winding start port, and the cable end projects from the winding start port.

When the winding start end of the cable is projected as described above, the drum is swung around and the outer jacket of the cable is damaged, and that portion is defective and unusable. Not only that, but if the protrusion becomes too long, it cannot be extended.

The object of the present invention is to solve the above problems and to start winding due to the accumulation of a gap generated between the drum body and the cable wound around the drum during the feeding of the cable from the drum. (EN) Provided is a projecting cable container in which a cable end of which a winding start end of a cable projects from a mouth is housed in a housing part and a shaft hole of a drum is reinforced.

[0013]

In order to solve the above-mentioned problems, the present invention integrally provides a mounting plate, which is fitted to the side surface of the cable drum, at one end of a cylindrical body having a diameter smaller than the shaft hole of the cable drum. Along with this mounting plate, an opening communicating with the inside of the cylindrical body is provided, and the cylindrical body has an axially intermediate portion that bulges in the radial direction and has a diameter larger than that of the axial hole. A plurality of slits extending in the axial direction from one end to the other end of the cable drum are detachably press-fitted into the shaft hole of the cable drum. A protruding cable accommodating container provided with a protruding cable accommodating portion for accommodating a cable protruding from the starting opening.

[0014]

The present invention has the above-mentioned structure, and when the cylinder is inserted into the shaft hole of the drum, the portion having a larger diameter than the shaft hole is compressed by the shaft hole, and the shaft hole is pressed into contact with the cylinder body. Is fixed in the shaft hole.

Therefore, when the drum is suspended by hooking the shaft hole or by hooking the shaft passing through the shaft hole, the suspension force is first transmitted to the cylindrical body and dispersed, and the dispersion is performed. The generated force is transmitted to the inner surface of the shaft hole of the drum.

When the cable is unwound from the drum, the end of the winding start of the cable is pulled out of the rim from the winding start opening provided in the rim and is inserted into the cable container.

[0017]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the embodiment of FIGS. 1 to 3, A is a cable drum having the same structure as that of the conventional example shown in FIG. 4, and 11 is a mounting plate applied to the side surface thereof.

The mounting plate 11 is provided at one end of a cylindrical body 10 which is inserted into the shaft hole 2 of the cable drum A, and is entirely made of structural steel or reinforced plastic. It leads to 11 openings.

The entire cylindrical body 10 has a diameter smaller than that of the shaft hole 2, and only the middle portion thereof bulges in the radial direction to have a larger diameter than that of the shaft hole 2. A plurality of slits 12 extending in the axial direction from one end to one end are provided.

Further, a part of the mounting plate 11 is bulged outwardly to form a cable accommodating portion 13. The accommodating portion 13 is positioned so as to cover the winding start port 6 of the drum A, and the cable that has protruded. Secure a space long enough to accommodate.
In the embodiment, it is provided so as to extend over the entire circumference of the side surface of the drum A.

In the above embodiment, after inserting the end portion of the cable 7 into the winding start port 6 and winding the cable around the case 4, the both ends of the small splits 9 are fixed to the outside of the collar 5 to fix the cable. Protect.

When the cylinder 10 is pushed into the shaft hole 2, the large diameter portion of the cylinder 10 is compressed in the radial direction and fixed to the shaft hole 2 by being pressed against the shaft hole 2, and at the same time the mounting plate is attached. 11 is in contact with the side surface of the drum A, and the cable housing portion 13 covers the winding start port 6 of the drum A.

[0023]

As described above, according to this invention, since the winding start end of the cable wound around the drum body is inserted into the cable housing portion, a gap is generated between the drum body and the cable wound around the drum body. Even if the winding start end of the cable protrudes from the winding start port, it enters the container, so that the winding start end of the cable protrudes from the drum, and there is no inconvenience that the outer cover of the cable is damaged and the portion becomes unusable.

Further, since the cylindrical body integral with the support plate is pressed against the inner surface of the shaft hole at the central bulge, it can be stably fixed by simply inserting the cylindrical body into the shaft hole, and at the same time the cable accommodating portion can be wound. Since the opening is covered, the cable housing can be easily provided in the conventional cable drum.

Further, when the drum is suspended by hooking the shaft hole or by hooking the shaft passing through the shaft hole, the suspension force is first transmitted to the cylindrical body and dispersed, and the dispersion is performed. Since the applied force is transmitted to the inner surface of the shaft hole of the drum, damage to the shaft hole is prevented. Therefore, it is possible to maintain the smooth rotation of the drum and the uniformed tension when the electric cable is paid out for a long period of time.
