Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for preventing rolling of a cable drum, and more specifically, a method for preventing rolling of a cable drum when the cable drum is transported on a vehicle. Regarding.

[Conventional technology and its problems]

Drums are the main packaging material for electric wires and cables (hereinafter referred to as cables). When packing cables on this drum, generally, as shown in Figure 7, the cables are wound in a line around drum D, the end of the winding is fixed to the flange of the drum with a rope, etc., and then the cable is wrapped around both drum flange F. A geta board (a) is installed across it, and a steel wire (b) or steel tape is wrapped around it and fixed. For this fixation, nails are used in the case of wooden drums, and special fasteners are used in the case of metal drums.

Packing the cables completely as described above would increase packaging costs, so cheaper drum packaging was considered.For example, the surface of the cables wound in an aligned manner on the drum was reinforced with strings, etc., as shown in Figure 5. Simple packaging has become common, which consists of wrapping an armor-like packaging material B, which is made by pasting short lengths of plywood or hard plastic boards around moisture-proof paper, and then tightening it with steel tape C or the like.

This simple packing poses no problem if the packed cable is handled under normal conditions, but if the drum D rolls and the collar F of the drum D collides with the cable wound around another drum D. , said packaging material B
damage the cable by tearing it.

As shown in Figure 6, when the packaged cables D are transported in tandem with the outer circumferential surface of the collar F facing the vehicle H, as shown by the chain line in the figure,
This vibration causes the drum D to shift in the axial direction, causing the drum D to roll, resulting in an even bigger problem.

As a means of solving this problem, as shown by the chain line in the same figure,
Although a plywood board G is interposed between each drum D, the plywood board G may shift due to vibration, and the flange F of the drum may collide with the cable of another drum D.

In view of the above problems, an object of the present invention is to provide a method for reliably preventing loaded drums from shifting or rolling in the axial direction due to vibrations during the process of transporting the simple drum packing cables by vehicle. This is what we are trying to provide.

[Means to solve the problem]

In order to achieve the above object, the present invention includes:
When multiple cable drums with flanges are lined up in tandem with their flanged outer circumferential surfaces facing each other, as in the above-mentioned vehicle loading,
A flange clamping tool having a pair of stop plates on both sides of the boundary plates, each separated by the width of the opposing flange outer peripheral surfaces, is attached to the flanges of adjacent cable drums, with the boundary plate interposed between them. Fit the pair of retaining plates so that they are applied to the inner and outer surfaces of the collar, press the tip of a push screw threaded through the outer retaining plate against the outer surface of the collar to fix the collar clamping tool to the collar, and fix the collar clamping tool to the collar. Therefore, the structure is such that the adjacent cable drums are connected and fixed.

[Effect]

In the present invention configured as described above, the drum flanges arranged in tandem are connected and fixed by the flanges clamping tool to prevent axial displacement and rolling between the drums loaded in a vehicle.

〔Example〕

Figure 3 shows the drum collar clamping tool T used in the present invention.
In this example, a U-shaped steel 1 is cut to a certain length, and the two drum flanges F are placed back to back with a gap between them, and the two are welded together across a flat plate 5 in the middle. A female thread 2 is formed on a U-shaped steel 1, and a set screw 3 is set thereon via a press seat 4. The set screws 3 may be provided on both sides of the flat plate 5.

As shown in Fig. 4, another clamping tool T' is used when the widths of the drums D arranged in a row are different from each other. They are welded back to back at different positions, and the setscrews 3 are provided in the same way as described above.

Next, an example in which the present invention is applied to truck transportation will be explained.

First, as shown in FIG. 6, cable packing drums D are arranged in tandem on the loading platform of a vehicle M, for example, a truck, as in the conventional method. As shown in FIG. 1 or 2, a collar clamping tool T or T' is fitted into the adjacent flanges F of the drums D arranged in a row, and at the same time, the set screws 3 are tightened to connect and fix the adjacent drums D. This collar clamping tool T,
T' allows each drum D to be connected and fixed so that it will not shift even if it vibrates.

〔effect〕

As is clear from the above description, according to the present invention, by connecting the flanges of each drum with the flanges clamping tool, axial movement and rolling of the drums due to vibrations during tract transportation etc. can be prevented, and therefore , to prevent the drum guard from colliding with the product (cable) and protect the product.
