Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a cable drum around which various cables are wound, and in particular, a cable drum equipped with a stopper that is convenient to install on the floor or at a cable installation work site, and that can reliably prevent movement of the cable drum. Regarding cable drums.

When installing a cylindrical cable drum with flanges on both sides so that the cables can be pulled out on the floor or at a cable installation site, install the attached cable drum as shown in Figure 1 to prevent the cable drum from moving. cable drum 1
A total of four pieces of wood 3 are applied to the circumferential surface of the flange portions 2, 2 at the front and rear.

However, it is inconvenient to transport these wooden pieces 3 for the stopper to a cable installation site, etc., since it is bulky and there is a fear that they may come off.

Furthermore, when installing on a concrete floor, cable 4
The wooden piece 3 moved in the pulling direction, making it difficult to securely fix it. Additionally, the way in which external force is applied to the cable drum differs depending on the position at which the cable is fed out from the cable drum. In other words, when the cable is fed out at a position that is offset from the center line in the width direction of the cable drum, In order to apply a rotational moment to the cable drum in a horizontal plane, it is necessary to prevent positional displacement in the width direction due to this rotational moment.

The present invention has been made based on the above-mentioned circumstances, and a splittable stopper is detachably attached to a storage hole provided in a flange portion of a cable drum to facilitate transportation, etc., and to facilitate movement of the cable drum during use. To provide a cable drum with a stopper that can reliably prevent movement especially in the width direction.

The present invention will be explained below based on embodiments shown in the drawings.
In FIG. 2, a plurality of storage holes 13 are provided in the flange portions 12 provided on both sides of the cylindrical portion 11 for winding cables of the cable drum 10. As shown in FIG.

The cable drum 10 is preferably made of a material other than wood, such as metal or plastic, since it is necessary to form the inner diameter of the storage hole 13 with a predetermined precision. This storage hole 13 has a stopper 14 as shown in FIG.
is stored. That is, the outer diameter of the stopper 14 is formed to match the inner diameter of the storage hole 13 with a certain precision of iron fitting, and in the embodiment shown in parentheses, it is divided into two parts.
This stopper 14 has a semi-circular hollow in the center and has a flat bottom plate 15 in the radial direction. A protruding pin 16 is provided at one end of the bottom plate 15, and the protruding pin 1
6 are iron-fitted with through holes 17 provided in the opposing flat bottom plate 15, and are integrally combined into a cylindrical shape. The thickness of the stopper 4 is provided to prevent it from coming off the storage opening 13. Lock mechanism L
It is equipped with That is, a steel ball 20 is supported in a through hole bored vertically in the flat bottom plate 15 via a set screw 18 and an elastic member 19, and in a normal state projects slightly on the outer periphery of the stopper 14. Further, a locking piece 21 is provided on the outer peripheral green portion of the stopper 14 facing the steel ball 20.

Cable drums 10 are installed on both sides of the stopper 14 in the width direction.
A movable plate 22 is provided to sandwich the flange portion 12.
This moving plate 22 is formed to have a shape that is almost the same as the outer shape of the stopper 14, and has a long hole 23 in the radial direction near the end of the semi-circular moving plate 22.
4, the main body 14a of the stopper 14 and the movable plate 22 are supported so as to be slidable in the horizontal direction.

To store the stopper 14 configured as described above in the storage hole 13 provided in the flange portion 12 of the cable drum 14, hold the flat bottom plates 15, 15 of the stopper 14, and hold the stopper 14 in the storage hole 13.
3, the steel ball 20 protruding from the outer peripheral surface of the stopper 14 is depressed into the through hole 17 against the elastic member 19 and can be inserted.

Then, the steel ball 20 protrudes toward the outer peripheral surface of the stopper 2ZOO at the position where the edge of the locking piece 21 and the surface of the flange 12 come into contact, and the entire stopper 20 is positioned and fixed. on the other hand,
When removing the stopper 14, the flat bottom plate 15 is removed.
, 15 and pull it outward.The removed stopper 14 is uncombined as shown in FIG. Install it on the ground, etc. at the installation location.

Next, when the cable 25 is pulled out, the cylindrical part 11 rotates about a shaft (not shown) inserted between the flange parts 102. In this case, the tip of the protruding pin 16 of the stopper 14 and one end of the flat bottom plate 15 receive a load in the cable pulling direction. Since the protruding pins 16 are in contact with the outer periphery of the protruding pins 12, a force is exerted to press the protruding pins 16 against the floor surface or the ground, and the cable drum 10 is reliably fixed at the installation position without slipping in the horizontal direction. Furthermore,
If the movable plate 22 of the stopper 14 is slid in the horizontal direction and grips the lower edge of the flange portion 12 of the cable drum 10 as shown in FIG. 10 can be prevented from shifting in the width direction by the moving plate 22.

FIG. 7 shows another embodiment of the stopper plate provided on the stopper 14, and FIG.
It is pivoted 25 to the lower part of the main body of No. 4.

When in use, the flat bottom plate 15 prevents the cable drum 1 from being spread further by approximately 180 degrees as shown by the chain line.
It becomes possible to prevent the positional shift of 0 in the width direction. In addition, FIG. B shows another embodiment of the sliding mechanism of the movable plate 22 that slides in the horizontal direction.
A horizontal dovetail groove 26 is provided at the lower end of the movable plate 22, and a protrusion 27 that fits into the dovetail groove 26 is formed on the movable plate 22.

It should be noted that various other shapes can be considered for the shape of the moving plate, the sliding mechanism, or the side of the rotating machine, and in short, any shape that can grip the flange portion of the cable drum when the stopper is used is sufficient. As described above, the cable drum of the present invention is equipped with a stopper that can be inserted and removed with a one-touch operation, and the Z stopper of the bracket is provided with a movable plate that can prevent movement not only back and forth in the cable feeding direction but also in the width direction of the cable drum. Therefore, the cable drum can be securely fixed to the installation location, and since it can be stored in the storage opening of the cable drum, it is convenient to transport, and there is no fear that the stopper will come off.
