DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a drum packing device particularly suitable for packing a drum used for shipping a thick cable.

[0002]

2. Description of the Related Art In the prior art, in order to pack a cable drum, a plurality of crossbars are straddled across the flanges of the drum, and fixed, a steel plate is wound and fixed, or a thin sheet of paper, cloth or the like is used. It is fixed by winding a sheet or by combining a crosspiece and a thin sheet.

[0003]

In the prior art method, when packing is carried out by stretching a crosspiece or an iron plate, the striatum in the drum is reliably protected from trauma, but the workability of the packing is low and the material of the packing is low. The cost is high, the materials cannot be reused, and there is a risk that the packing material, such as a crosspiece or an iron plate, may come into contact with the striatum in the drum and damage the striatum during unpacking.

[0004] On the other hand, sheet-like packing materials such as paper and cloth are inexpensive and easy to fit into the striated body in the drum and have high workability in packing. However, they are vulnerable to wind, rain and external damage, and are reused. There were drawbacks that could not be done.

An object of the present invention is to provide a drum packaging which avoids the above drawbacks, is inexpensive, has good workability, is resistant to wind and rain, and is resistant to external damage, and can be reused.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention provides a plurality of strip-like elastic reinforcing blocks having elasticity in a thickness direction and a length direction and arranged at intervals from each other. And a flexible connecting sheet member for connecting these elastic reinforcing blocks to each other.

[0007]

As described above, when the drum packing device is formed in a belt shape, it can be wound around the drum and easily fixed with a rope or the like with high workability, and also in the thickness direction and the length direction.
Use multiple strip-shaped elastic reinforcing blocks with elasticity
Together with these multiple strip-shaped elastic reinforcement blocks
Because it is connected by a flexible connecting sheet member by opening
Overall wrap reliably easily rather striatum familiar along the unevenness of the striatum in the drum so flexible in any direction
And easy to wind around the drum, improving workability
Above, the strip-shaped elastic reinforcing block reliably protected <br/> strong damage, the striatum from shock and external environment for trauma and weathertight
Can be reused at the same time.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a drum packing device according to an embodiment of the present invention; FIG.
The drum packing device 10 includes a plurality of strip-shaped elastic reinforcing blocks 12 having elasticity in the thickness direction and the length direction and arranged at intervals from each other, and the strip-shaped elastic reinforcing blocks 12. And a flexible band-shaped connecting sheet member 14 for connecting the members to each other.

The strip-shaped elastic reinforcing block 12 is made of a cushion material having appropriate hardness and elasticity, for example, a foamed material such as foamed polyurethane, foamed polyethylene, or foamed polystyrene, or urethane rubber formed appropriately thinly.
It can be formed from a rubber material such as butyl rubber or a plastic sheet with an air gap such as a plastic sheet provided with a large number of single cells.

The flexible connection sheet member 14 is preferably, for example, a commercially available plastic sheet called a Canary sheet, which is formed by laminating a reinforced film on both sides of a high-density polyethylene sheet. Plastic sheet. In addition, as the flexible connection sheet member 14, a vinyl or polyethylene sheet or a sheet of cloth or the like can be used.
All of these are required to have waterproofness. In the illustrated embodiment, the flexible connection sheet member 14 is connected to the strip-like elastic reinforcing blocks 12 by being attached so as to sandwich the strip-like elastic reinforcing blocks 12 up and down.

In the illustrated embodiment, a pair of rope stoppers 16 and 16 'fixed to the flexible connecting sheet member 14 on one surface corresponding to the strip-like elastic reinforcing blocks 12 penetrate. Ropes 18 and 18 ′ are used to wind and fix the drum packing device 10 around the drum 20 (see FIG. 4).

Next, referring to FIG. 4, the use state of the drum packing device 10 of the present invention is as follows. After the wire 20 such as a cable is wound around the drum 20, the band-shaped drum packing device 10 is placed thereon. And wrap it around. As described above, since the strip-shaped elastic reinforcing blocks 12 have appropriate elasticity in the thickness direction and the length direction, as shown in FIG. At the same time drum with 20 wound and the striatum 22 can wrap Mukoto while familiar
The striatum 22 is easy to be damaged and resistant to trauma and wind and rain.
The can be reliably protected, also rope 18, 18 '
, The drum packing device 10 can be easily fixed. Also, the drum packaging component may solve the rope can easily be unpacked, when not in use as shown in FIG. 3, while can be stored folded, be reused
You can also.

[0013] As a specific example of the drum packing device of the present invention, foamed polyurethane is used as a strip-like elastic reinforcing block, and its thickness, width, length, and mutual interval are respectively t,
w, L and 1 were used, and a Canarian sheet was used as a flexible connecting sheet member. Numeric values in the following ranges can be set as t, w, and l. t = 5 to 15 mm w = 100 to 500 mm l = 30 to 100 mm In addition, various types of L are prepared according to the length of the axis of the drum. It may have an excess width.

As a specific example of the present invention, for example, t = 10
mm, w = 250 mm, L = 2900 mm, using a strip-shaped elastic reinforcing block made of foamed polyurethane, and as a flexible connecting sheet member, the width W is slightly larger than L = 12.
A Canarian sheet of 0 to 550 mm was used. A pair of ropes were attached using rope stops as shown.

When the drum packing device thus formed was used for drum packing of a 275 kV, 1 × 2500 mm power cable, the wrapping workability was good and the packing device was well adapted to the cable. It was confirmed that the packaging could sufficiently cope with the change of the protrusion and the change of the layer.

In the above embodiment, the case where the strip-shaped elastic reinforcing blocks 12 are arranged in a line is shown, but they may be arranged in two lines as shown in FIG.

[0017]

According to the present invention, as described above, since the drum packaging is formed in a flexible band shape, it can be easily fixed with high workability by winding it around the drum. Also , it has elasticity in the thickness direction and the length direction.
Use multiple strip-shaped elastic reinforcing blocks
These strip-shaped elastic reinforcing blocks can be spaced at intervals.
Because it is connected by a flexible connection sheet member, overall
The striatum in the drum because it is flexible in any direction
It is wrapped an easy rather than the striatum familiar along the unevenness of the certainty
In addition to being easy to wind around the drum and improving workability,
Saku elastic reinforcing block is strong against trauma and weathertight
To ensure that the striatum is protected from impact and the external environment.
There are benefits that can be reused as much as possible .
