Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to an emergency drum wrapped with an emergency cable that is temporarily installed during the restoration of communication lines in the event of a disaster.

(Prior Art) An emergency cable laid in an accident section of a communication line is wound around an emergency drum with closures for connecting the wire cores attached to both ends of the emergency cable.

FIG. 6 is a schematic vertical sectional view of a conventional emergency drum. In this figure, the emergency drum 1 includes a winding drum 2, a collar plate 3.4 fixed to both ends thereof, and one of the collar plates 3.4 on the winding drum 2, for example, one of the collar plates 3.4 is installed biased toward the collar plate 3 side. a separator 5 having notches 5a distributed in the circumferential direction on a disc and reaching the outer periphery of the winding drum 2; and a closure tray 6 detachably attached to the inner surface of the first flange plate 3. , 7.

In the conventional emergency drum 1 having the above configuration, the emergency cable 8 is wound between the separator 5 and the collar plate 4, and closures 9 and 10 are attached to the start and end of the winding.

Each of the closures 9.10 is attached to the inner surface of the first flange plate 3 of the emergency drum via a closure receptacle 6.7.

After the closure 9 at the winding start end of the emergency cable 8 is attached and fixed to the closure tray 6, the emergency cable 8 is wound several times around a portion 11 between the collar plate 3 and the separator 5 (cable end unaccommodated portion) of the winding drum 2. , and is guided to the portion of the winding drum 2 between the separator 5 and the separator 5 through one of the other notches 5a of the separator 5, and is wound and stored in this portion.

Thus, the winding end of the emergency cable 8 is wound several times around the cable end unaccommodated portion 11 via the other negative notch 5a of the separator 5, and is wrapped around the closure 10 at the end of one winding.
is attached and fixed to the closure tray 7.

The winding and rewinding of the emergency cable 8 can be carried out by fixing the shaft of a drum driving device to the winding drum 2 and rotating the emergency drum 1, or by using an under roller type drum driving device. This is done by rotating the emergency drum 1.

(Problems to be Solved by the Invention) In the conventional emergency drum described above, each closure 9.10 is fixed to the inner surface of the first collar plate 3, so the length of the emergency cable may vary depending on the length of the emergency cable. The positions of the closures 9.10 at the start end and the winding end overlap, making it difficult to support and fix the closures 9.10 to the collar plate. In such a case, it was necessary to loosen the cable at the end of the winding and shift the position of the closure tray.

When slack is formed as described above, it is necessary to provide a cable holding rod to support the slack and prevent the cable from sagging.

Furthermore, in order to adjust and change the mounting position of the closure saucer as described above, it is necessary to provide a plurality of mounting holes for mounting the saucer in the flange plate, distributed in the circumferential direction.

Furthermore, as described above, the start part of the emergency cable 8 is first wound around the cable end unaccommodated part 11, and the end part is wound thereon, so that the cable end on the start side is wrapped around the entire length of the cable. I couldn't take it out without turning it back.

The present invention has been made based on the above-mentioned circumstances, and it is possible to easily take out and wind up the cable end at the beginning of winding, and also to have one hole for attaching a closure tray for fixing the cable end at the end of winding.
The purpose of the present invention is to provide an emergency drum that requires only one location.

[Structure of the Invention (Means for Solving the Problems) The emergency drum of the present invention includes a drum shaft, a winding start side winding drum integral with a first collar plate, and a cable winding winding body integral with the drum shaft. a winding end side winding drum that is integral with the second flange plate; a separator that is integrally provided at both ends of the cable winding drum; It is characterized by comprising a support means for supporting and fixing, and a coupling means for releasably coupling each of the collar plates and the end of the drum shaft.

(Function) In the emergency drum of the present invention having the above configuration, the coupling means is released to free the winding end side winding drum with respect to the drum shaft, and the winding of the emergency cable wound around the winding end side winding drum is made free. It is slid and rotated relative to a portion near the end, so that the position of the end of the winding coincides with the position of the support means attached to the flange plate. Thereby, no matter where the end of the winding is located depending on the length of the emergency cable, it can be supported and fixed by the supporting means.

In addition, the winding start end of the emergency cable is wound around the winding trunk on the winding start side,
Since the end of the winding is wound on the end-side winding drum and the end of the winding is not wound over the beginning of the winding, it can be taken out without having to rewind the entire length.

(Embodiment) FIG. 1A is a longitudinal sectional view of an embodiment of the present invention, FIG. 1B is a front view thereof, and FIG. 1C is a partially cutaway side view thereof. In FIG. 1A, the drum shaft 21 of the emergency drum 20
is provided with small diameter portions 21a having equal axial dimensions at both ends,
It is a hollow shaft with an end flange 21b provided at one end and an open end at the other end, and a cable winding drum 22 is provided integrally with the drum shaft 21 at the large diameter section 21c in the middle. Separators 23 are provided integrally at both ends of the winding drum 22, respectively. Separator 23
are equally spaced in the circumferential direction, and are installed in four locations protruding in the radial direction.

Further, on the side of the end flange 21b of the small diameter portion 21a, a winding start side winding drum 25 which is integral with the first collar plate 24 and has the same diameter as the cable winding winding drum 22 is located at the center of this winding drum. It is rotatably mounted by bearings 26.26.

Further, on the other side of the small diameter portion 21a, a winding end side winding drum 28 is integrally formed with a second collar plate 27 and has the same diameter as the cable winding winding drum.
is rotatably attached by a bearing 29 at the center of the winding drum.

Note that the open end of the drum shaft 21 is provided with a removable end flange 21d. Each end flange 21b, 21d is provided with a plurality of lock pins 3o, 31 equally spaced in the circumferential direction.

Each is connected to a first collar plate 24,27.

In the embodiment with the above configuration, the emergency drum 20 is driven by an underground roller type drum driving device. Here, the winding of the emergency cable 32 around the emergency drum 20 will be explained. When winding the emergency cable, first, the lock pin 30 of the end flange 21b of the drum shaft 21 is removed and the connection with the corresponding first collar plate 24 is released. In this state, the closure 33 at the winding start end of the emergency cable 32
is supported and fixed to a closure tray 34 fixed to the first flange plate 24 integral with the winding start side winding drum 25, and the emergency drum 20 is rotated a required number of times by the under roller type drum driving device (not shown).

As a result, the starting end of the emergency cable 32 is aligned with the starting side winding drum 25.
It is wound as much as necessary.

Next, the emergency cable 32 is transferred from between the separators 23 to the cable winding drum 22, and the end flange 20b is
The rotation of the emergency drum 20 is continued by coupling with the collar plate 24 of the drum. Then, the emergency cable 32 is gradually wound around the cable winding drum 22, and eventually almost its entire length is wound around the cable winding drum 22.

Here, a portion of the emergency cable 32 near the winding end is transferred from between the separators 23 to the winding end side winding drum 28,
Further, the rotation of the emergency drum 20 is continued. As a result, the portion near the winding end is wound around the winding drum 28 on the winding end side, leaving the closure 35 at the winding end. Finally, the closure 35 at the end of the winding is supported and fixed to the closure tray 36 to complete the winding of the emergency cable 32.

Hereinafter, the closure saucer 3 and the invention will be described in detail with reference to FIGS. 2A, 2B, 3A, and 3B. Note that since the closure trays 34 and 36 have the same configuration, only the closure tray 36 will be described. FIG. 2A is a side view of the closure tray, and FIG. 2B is an enlarged front view thereof. In these figures, the closure trays 36 are provided on a flat bottom plate 36a and located near both longitudinal ends of the bottom plate 36a, and have a concave curved surface that is convex toward the bottom plate 36a with a curvature matching the outer diameter of the closure 35. Pillow 36 exhibiting
b, 36b.

Further, one leg of the bracket 37 is fixed to the lower surface of the bottom plate 36a, and the other leg is provided with a through hole 37a for attachment located near the bottom plate.

Near the tip thereof, an arc-shaped long hole 37b is provided with the attachment through hole 37a as the center.

Additionally, downwardly opening hooks 38 for locking a binding belt are provided at the upper portions of both sides of the pillows 36b, 36b, respectively.

3A and 3B, the binding belt 39 has a rectangular engagement ring 40a at one end and a buckle 4 with a stopper at the other end.
0b, and a second portion 41 having an engaging ring 41a similar to the aforementioned engaging ring at one end.

Note that 40c in the figure indicates a stopper.

The closure tray 36 having the above structure has the through hole 3 for attachment.
7a, it is attached to the second flange plate 27 of the drum using the arcuate long hole 37b. Note that details of this attachment mode will be explained later.

The closure 35 is attached to the closure tray 36, which is temporarily attached to the drum collar as described above, in the following manner. That is, the circumferential surface between the protrusions of the closure 35 is connected to the pillow 36b of the bottom plate 36a of the closure tray 36,
36b, and place the closure 35 on the closure receiving tray 36. Next, the engagement ring 40a of the first portion 40 is engaged with one of the hooks 38 on both sides of the pillows 36b, 36b, and the second portion 41 is engaged with the other.
The engagement rings 41a of the two are engaged. The tip of the second portion 41 is inserted into the stopper buckle 40b of the first portion 40, and the second portion 41 is pulled to attach the closure 35 to the closure tray 36.

Depending on the length of the emergency cable 32, the position of the closure 35 at the end of the winding may not match the position of the closure tray 36, which is pre-attached to the second collar plate 27, and if this is done, the closure 35 will not be supported by the closure tray 36. It may not be possible to fix it.

In the present invention, in such a case, the closure 35 can be supported and fixed to the closure tray 36 in the following manner. First, the lock bin 31 is removed and the connection between the end flange 21d and the second flange plate 27 is released to free the winding drum 28 at the end of the first roll with respect to the drum shaft 21. Here, the winding end side winding drum 28 is attached to the emergency cable 3 wound thereon.
Rotate it while sliding it against the part near the end of the winding No. 2,
The position of the closure 35 at the end of the winding is matched with the position of the closure receiving tray 36. Thereby, regardless of the position of the closure 35 at the winding end depending on the length of the emergency cable 32, it can be supported and fixed to the closure receiving tray 36 fixed to the second flange plate 27. Moreover, the number of cable press bars installed can therefore be reduced.

Further, the winding start end of the emergency cable 32 is wound around the winding start side winding drum 25, and the winding end is wound around the winding end side winding drum 28, so that the winding end is overlapped with the winding start end. Therefore, the starting end of the emergency cable 32 can be taken out without having to rewind the entire length of the emergency cable 32.

The bracket 37 is attached to the second collar plate 27 in the following manner. That is, the through holes 37a for attachment are aligned with the attachment holes near the drum shaft 21, bolts are inserted through these through holes, and nuts are loosely screwed into the bolts. In this state, the arc-shaped elongated hole 37b of the bracket 37 is opposed to the mounting hole farther from the drum shaft 21, and a bolt is inserted into the mounting hole and a nut is screwed into the bolt.

In this state, the bracket 37, and therefore the closure tray 36, can rotate about the mounting through hole 37a of the bracket 37 within the range permitted by the arcuate long hole 37b.

The closure 35 is attached to the closure tray 36 in the following manner. First, the vicinity of the end of the emergency cable 32 is fixed to the second collar plate 27 with a string using a string hanging member (not shown).

Next, the direction of the emergency cable fixed as described above,
That is, the position of the bracket 37 is set in accordance with the direction of the closure 35, and the closure tray 36 is fixed by tightening a nut or the like. Here, the closure 35 is fixed to the closure tray 36 using the binding belt 39 as described above. As described above, since the closure tray 36 is fixed to the second flange plate 27 of the drum at two locations, the through hole 37a and the arcuate elongated hole 37b of the bracket, the closure tray 36 may be damaged due to vibrations during transportation of the drum. It won't move loose or fall off. Further, pillows 36b, 36b are provided on the saucer bottom plate 36a, and these pillows allow the closure 35 to be moved to the closure saucer 36 at a position where it does not interfere with the protrusion of the closure 35.
Since we are trying to support the government, our support will not be unstable.

Further, the closure 35 is bound to the saucer 36 by the pillow 36. b, hooks 38 provided on both sides of 36b.
The first part 40 and the second part 41 of the bondage belt 39 attached to the binding ring 38 by the engagement rings 40a and 41a,
Since they are connected and tightened by the stopper buckle 41b, there is no risk that the binding belt 39 will loosen due to photographing or the like.

Hereinafter, the removal of the emergency cable winding end closure 35 and the winding start end closure 33 will be explained using FIGS. 4A to 4C1 and FIGS. 5A to 5B.

FIGS. 4A and 4B are schematic diagrams showing the front and side views of the above-mentioned embodiment at the same time, with the end-of-volume closure 35 being taken out;
FIGS. 5A and 5B are schematic diagrams showing the side and front views of the above-mentioned embodiment at the same time and showing how the emergency cable winding start side closure 33 is taken out.

To take out the winding end closure 35 from the emergency cable winding state shown in FIGS. 1A and 1B, first remove the second collar plate 27.
and the drum shaft.

Next, the drum is tilted by a shaft (not shown) inserted through the drum shaft to lift the first collar plate 24 off the under roller (not shown), and the under roller is driven in the opposite direction to the direction used when winding the emergency cable. Then, the end winding drum 28 that is integrated with the second collar plate 27 is rotated at the same time as the second collar plate 27, and the emergency cable 32 wound around the first winding end winding drum 28 is rotated at the same time as the second collar plate 27.
It will stick out as shown in Figure A. If the above-mentioned rotation is continued, the end portion of the emergency cable wound around the end-side winding drum 28 will be unwound from the end-side winding drum 28, as shown in FIG. 4B. Here, the winding end side closure 3
5 from the closure tray and take it out.

In addition, the withdrawal amount of the closure 33 on the start side is as shown in Figure 5A, Figure 5.
As shown in Figure B, winding is carried out in the same manner as described above, except that the connection between the drum shaft and the first flange plate 24 is released, the inclination of the drum is reversed, and the second flange plate 27 is lifted off the under roller. The starting closure can be removed.

Note that the present invention is not limited to the above embodiments. That is,
Cable winding start side winding drum 1 The cable winding start end and winding end are fixed by the friction between the cable winding drum and the cable wound around them, so that the cable main body wound on the cable winding drum and the cable winding drum are fixed. Since the cables are separated, separators at both ends of the cable winding drum can be omitted in some cases.

[Effects of the Invention] As is clear from the above, in the emergency drum of the present invention, unlike conventional emergency drums, the positions of the closures at the start and end of one roll do not overlap;
It is not difficult to support and fix each closure to the collar plate.

In addition, as mentioned above, when installing the closure saucer, the closure at the end of the winding is fixed to the collar plate without adjusting or changing the position. It is not necessary to provide them distributed in the circumferential direction.

Furthermore, since the winding start end and winding end of the cable are wound separately as described above, the winding start end can be taken out without having to rewind the entire length of the cable.
