Then, the emergency cable 30 is gradually wound around the cable winding drum 22, and eventually almost its entire length is wound around the cable winding drum 22.

Here, the part near the winding end of the emergency cable 30 is moved 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 33 at the winding end. Finally, the closure 33 at the end of the winding is supported and fixed to the closure receiving tray 34 to complete the winding of the emergency cable 30.

The details of the closure tray 32, 34 will be explained below with reference to FIGS. 2A, 2B, 3A, and 3B. In addition, since the closure trays 32 and 34 have the same configuration,
Only the closure tray 34 will be explained. Figure 2A
2B is a side view of the closure tray, and FIG. 2B is an enlarged front view thereof. In these figures, closure pan 34
has a flat bottom plate 34a, and pillows 34b, 34b, which are located near both longitudinal ends of the bottom plate and have a concave curved surface convex toward the bottom plate 34a with a curvature matching the outer diameter of the closure 33. .

Further, one leg of the bracket 35 is fixed to the lower surface of the bottom plate 34a, and the other leg is provided with a through hole 35a for attachment located near the bottom plate.

Near the tip thereof, an arc-shaped long hole 35b is provided with the attachment through hole 35a as the center.

Furthermore, downwardly opening hooks 36 for locking a binding belt are provided at the upper portions of both sides of the pillows 34b, 34b, respectively.

3A and 3B, the binding belt 37 has a rectangular engagement ring 38a at one end and a buckle 3 with a stopper at the other end.
8b, and a second portion 39 having an engaging ring 39a similar to the aforementioned engaging ring at one end.

Note that 38c in the figure indicates a stopper.

In FIG. 1B, a large number (28 holes in the figure) of through holes 40 are equally spaced on a small diameter concentric circle of the first flange plate 27, and the arc shape of the bracket 35 is smaller than the radius of the concentric circle. long hole 3
A through hole 41 is formed on a concentric circle having a larger radius by the diameter of 5b, facing each other on the radius of each of the through holes 40 and the first flange plate 27.

Further, on the middle radius of the through-holes 40, 41, a U-shaped string hanging member 42 is provided in a staggered manner with the large-diameter concentric circle interposed therebetween.

The closure tray 34 having the above structure has the through hole 3 for attachment.
5a, it is attached to the first flange plate 27 of the drum using the arc-shaped elongated hole 35b. The details of this mounting manner will be explained later.The closure 33 is attached to the closure receiving tray 3 which is temporarily attached to the drum flange as described above.

That is, the closure 33 is placed on the closure tray 34 with the surfaces between the protrusions of the closure 33 brought into contact with the pillows 34b, 34b of the bottom plate 34a of the closure tray 34. Next, the engagement lJ38a of the first portion 38 is engaged with each one of the hooks 36 on both sides of the pillows 34b, 34b,
The engagement ring 39a of the second portion 39 is engaged with the other end. The tip of the second portion 39 is inserted into the stopper buckle 38b of the first portion 38, and the second portion 39 is pulled to attach the closure 33 to the closure tray 34.

Depending on the length of the emergency cable 30, the position of the closure 33 at the end of the winding may not match the position of the closure tray 34, which is pre-attached to the first collar plate 27, and if left as is, the closure 33 will not be supported by the closure tray 34. It may not be possible to fix it.

In such a case, the mounting position of the bracket 35 with respect to the first collar plate 27 is adjusted as follows to correspond to the length of the emergency cable 30. That is, the through hole 35 for mounting
Insert the emergency cable 3 into the through hole 41 on the concentric circle with diameter a.
Bolts (not shown) are inserted through these through holes in alignment with those near the end of the winding of No. 0, and nuts (not shown) are loosely screwed into the bolts. In this state, align the arc-shaped elongated hole 35b of the bracket 35 with the large-diameter concentric through-hole 41 facing the through-hole 4O, insert the bolt through them, and screw the nut onto the bolt. put.

In this state, the bracket 35, and thus the closure tray 34, can rotate about the mounting through hole 35a of the bracket 35 within the range permitted by the arcuate elongated hole 35b.

The closure 33 is attached to the closure tray 34 in the following manner. First, the vicinity of the end of the emergency cable 30 is tied to the first collar plate 2 using the string hanging member 42.

Next, the position of the bracket 35 is set in accordance with the direction of the emergency cable fixed as described above, that is, the direction of the closure 33, and the closure tray 34 is fixed by tightening a nut or the like. Here, the closure 33 is fixed to the closure tray 34 using the binding belt 37 as described above.

In the emergency drum of this embodiment, regardless of the position of the closure 33 at the end of the winding, one of the pairs of through holes 40 and 41 distributed in the circumferential direction is used to close the first flange plate. It can be fixed at 27. In addition, since the closure tray 34 is fixed to the first flange plate 27 of the drum at two locations, the through hole 35a and the circular arc-shaped elongated hole 35b of the bracket, the closure tray 34 may loosen due to vibrations during transportation of the drum. It will not move or fall off.

Further, the receiver 34 is provided with pillows 34b, 34b, and these pillows support the closure 33 on the receiver 34 at a position that does not interfere with the protrusion of the closure 33, so that the support will not become unstable. do not have.

Furthermore, in the emergency drum of the present invention, since the string hooking members 42 are provided in a zigzag manner, these string hooking members 42
The vicinity of the end of the emergency cable 30 can be tied with a string, shaped as desired, and fixed to the first flange plate 27 of the drum, so that the closure 33 can be easily supported by the closure tray 34. . In addition,
At this time, the bracket 35 can be rotated around the through hole 35a of the bracket 35 within the range of the arcuate elongated hole 35b, and the angle of the saucer l can be adjusted to the direction of the shaped emergency cable 30 to perform 1IIW. .

The removal of the emergency cable winding end side closure 33 and the same winding start side closure 31 will be explained below.

4A and 4B are schematic diagrams showing the front and side views of the above-mentioned embodiment at the same time and showing how the winding start side closure 31 is taken out.6 From the emergency cable winding state shown in FIGS. 1A and 1B. To compare the end-of-winding closure 33, first remove the end-of-winding closure 33 from the first collar plate 27, support it with an appropriate movable means, and then use the emergency drum to wrap the emergency cable. Rotate in the opposite direction. This allows the emergency cable winding end closure to be taken out.

To take out the start-side closure 31, remove the second collar plate 2.
4 and the drum shaft, the entire drum is tilted by a shaft (not shown) inserted into the drum shaft, and the first flange plate 27 is lifted off the under roller (not shown).

Here, the Angler is driven in the opposite direction to the direction used when winding the emergency cable.

Then, the winding start side winding drum 25 integrated with the second collar plate 24
The emergency cable 30, which is rotated simultaneously with the collar plate 24 and wound around the start-side winding drum 25, extends out as shown in FIG. 4A. If the above rotation is continued, the start portion of the emergency cable wound around the start-side winding drum 25 will be rolled from the start-side winding drum 25, as shown in FIG. 4B. .

At this point, the end-of-volume closure 31 is removed from the closure tray and taken out.

Note that the present invention is not limited to the above embodiments. That is,
The cable winding start end and winding end are fixed due to friction between the cable winding drum at the start and end sides of the cable and the cable wrapped around them, so that the cable main body that is wound around the cable winding drum is fixed. In some cases, the separators at both ends of the cable winding drum can be omitted.

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

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