Description

The present invention relates to a cable holder that temporarily holds a large number of cables accommodated in a cable rack or the like upward.

  In general, a large number of cables (power cables, optical cables, etc.) are laid in facilities such as electric power and communication, and these cables are accommodated in a cable accommodating portion such as a cable rack. Among facilities where these cables are laid, for example, in communication facilities, it is necessary to lay new optical cables as the number of communication lines increases, especially when laying new optical cables in large-scale communication facilities. Then, new optical cables are further stacked on the optical cable group stacked in the cable rack.

  Then, when removing an unnecessary predetermined optical cable (such as an optical cable whose circuit has been abolished) from the optical cable group laid in the cable rack in such a state, the optical cable to be removed is identified and pulled out. I am doing so. At that time, when the optical cable to be removed is located at the upper part of the optical cable group, the optical cable can be easily removed, but when the optical cable to be removed is located at the lower part of the optical cable group, it becomes an obstacle. Several workers lifted the optical cable to expose the optical cable to be removed, and then pulled the cable out of the cable rack. However, it is necessary for several workers to remove the cable at the same location. There was a problem that work efficiency was bad. In addition, since several workers are lifting the optical cable, there is a problem that an abnormal tension is applied to the optical cable, which may affect the line. For this reason, an unnecessary predetermined optical cable cannot be easily removed, which causes an increase in the number of optical cables in the cable rack.

  In order to solve such a problem, a cable holder that temporarily holds a large number of cables accommodated in a cable rack upward has been proposed (see Patent Document 1).

In the present embodiment, the cable holder is attached to the right end portion of the cable housing portion 100. However, the cable holder 1 may be attached to the left end portion of the cable housing portion 100 by inverting the left and right sides. Not too long.

  First, the main body 10 will be described. As shown in FIGS. 1 and 2, at the lower part of the main body 10, an L-shaped L-shaped portion 21, an adjusting portion 22 attached so as to penetrate the horizontal portion of the L-shaped portion 21, and an adjusting portion A holding portion 20 including a holding plate 25 attached to an upper portion of 22 is provided. Then, by adjusting the distance L between the holding plate 25 and the lower surface of the main body 10 by rotating the adjusting portion 22, the right end of the cable housing portion 100 in the width direction is adjusted between the holding plate 25 and the lower surface of the main body 10. The main body 10 can be detachably attached to the cable housing portion 100 while being held.

  Further, a convex protrusion 102 is provided at the lower right side of the cable housing portion 100, and a projecting portion 103 projecting inward so that the opening portion 101 is narrower than the width of the cable housing portion 100 is formed in the opening portion 101. Is provided. On the other hand, an engaging portion 13 that engages with the protruding portion 103 of the cable housing portion 100 is provided on the lower left side of the main body 10, and a roller 26 is provided on the upper portion of the holding plate 25 of the main body 10. Then, the engaging portion 13 of the main body 10 and the protruding portion 103 of the cable housing portion 100 are engaged with each other, and the roller 26 of the main body 10 is positioned on the right side in the width direction with respect to the protruding portion 102 of the cable housing portion 100. By attaching 10 to the cable housing portion 100, it is possible to prevent the main body 10 from being detached from the cable housing portion 100. That is, by engaging the protruding portion 103 of the cable housing portion 100 and the engaging portion 13 of the main body 10, the main body 10 is prevented from moving to the right in the width direction over a predetermined distance with respect to the cable housing portion 100. On the other hand, by disposing the roller 26 of the main body 10 on the right side in the width direction with respect to the protruding portion 102 of the cable housing portion 100, the main body 10 moves to the left side in the width direction over a predetermined distance with respect to the cable housing portion 100. It is possible to prevent the main body 10 from being detached from the cable housing portion 100.

  Further, a plurality of rollers 16 are provided in the lower part of the main body 10 that comes into contact with the cable housing portion 100, and the main body 10 is connected to the cable in cooperation with the rollers 26 provided on the upper part of the holding plate 25 of the main body 10. The container 100 can be moved in the longitudinal direction (perpendicular to the paper surface of FIG. 1).

  A plurality of rollers 18 are juxtaposed above the opening 101 of the cable housing portion 100 of the main body 10 so that the rotation axis is parallel to the longitudinal direction of the cable housing portion 100, and slides on these rollers 18. A member 50 is placed. That is, the sliding member 50 is attached to the main body 10 via the plurality of rollers 18, and the sliding member 50 can be easily slid in the width direction (A direction) of the cable housing portion 100.

  Next, the sliding member 50 will be described. As shown in FIG. 3, the sliding member 50 is formed of a plate-like member, and a through hole 51 is provided at a right end portion in the longitudinal direction to form a grip portion 55. A plurality of rollers 58 are juxtaposed on the upper part of the sliding member 50 other than the grip portion 55 so that the rotation axis is parallel to the width direction, thereby forming a sliding means. These rollers 58 are configured such that, when the cable holder 1 is attached to the cable housing portion 100, the rotation axis is parallel to the longitudinal direction of the cable housing portion 100. Thus, by providing the sliding means on the upper part of the sliding member 50, as described later, there is an effect that the cable 110 is not subjected to an abnormal tension even if the sliding member 50 is slid.

  Next, the operation of the cable holder 1 will be described. 4-7 is a figure which shows the operation | movement process of a cable holder. First, as shown in FIG. 4, the cable holder 1 is attached to the right end of the cable housing portion 100 in the width direction. Here, it is assumed that the cable X to be removed is buried under a large number of cables in the approximate center of the cable housing portion 100. In order to remove the cable X from the cable housing portion 100, it is necessary to temporarily move the cable 110, which becomes an obstacle when removing the cable X, to another place. In the present embodiment, when the cable X is removed, all the cables 110 positioned on the right side and the upper side of the cable X are temporarily moved to another location.

  Therefore, as shown in FIG. 5, the sliding member 50 of the cable holder 1 is slid toward the left end in the width direction of the cable housing portion 100, and a part of the sliding member 50 is opened in the opening 101 of the cable housing portion 100. It arrange | positions so that it may be located above. And the area | region r1 which can mount the cable 110 on the sliding member 50 is ensured. At this time, since the sliding member 50 is placed on the plurality of rollers 18 provided in the main body 10, the sliding member 50 can be easily slid.

  Then, as shown in FIG. 6, the cable 110 existing in the region R <b> 1 is placed in the region r <b> 1 of the sliding member 50. Here, by adjusting the position of the sliding member 50, the cable 110 can be placed in the region r1 of the sliding member 50 without applying an abnormal tension when the cable 110 is moved. In other words, the cable existing in the region R1 can be placed in the region r1 of the sliding member 50 with the minimum movement distance.

  Next, after all the cables 110 existing in the region R <b> 1 are placed on the region r <b> 1 of the sliding member 50, the sliding member 50 is further slid toward the left end in the width direction of the cable housing portion 100. At this time, the cable 110 placed on the sliding member 50 also tends to move toward the left end in the width direction of the cable housing portion 100 as the sliding member 50 slides. Since the cable 110 is placed on the plurality of rollers 18 provided on the upper portion, the cable 110 slides on the sliding member 50, and the relative position of the cable 110 with respect to the cable housing portion 100 does not change, and only the sliding member 50 is present. The cable housing portion 100 slides toward the left end portion in the width direction. That is, the cable 110 placed on the sliding member 50 remains in place, and only the sliding member 50 slides toward the left end in the width direction of the cable housing portion 100. Thus, even if the sliding member 50 is slid toward the left end of the cable housing portion 100 in the width direction, the cable 110 placed on the sliding member 50 remains in place, so that the sliding member 50 is slid. However, there is an effect that no abnormal tension is applied to the cable 110.

  As a result of sliding the sliding member 50 toward the left end of the cable housing portion 100 in the width direction, the cable 110 can be further placed on the left end of the sliding member 50 as shown in FIG. A region r2 that can be obtained can be secured. The cable 110 existing in the region R2 is placed in the region r2. These operations are repeated until there is no longer any cable 110 that becomes an obstacle when the cable X is removed. Then, after the cable X is removed, the cable 110 placed on the sliding member 50 can be returned to the original state by performing the operation opposite to the operation described above.

  Further, the cable holder 1 is moved in the longitudinal direction of the cable housing portion 100 (perpendicular to the plane of the paper in FIGS. 4 to 7), and the above-described operation is repeated, so that the cable X is connected to the cable housing portion. 100 can be completely removed. And if the cable holder 1 is used, since removal of a cable can be performed safely by one person, the efficiency of removal work can be improved.

  As described above, according to the cable holder 1 according to the present embodiment, the cables 110 other than the cable 110 to be removed among the many cables 110 accommodated in the cable accommodating portion 100 are not adversely affected. The cable 110 to be removed can be easily and safely removed, and the efficiency of the removal work can be further improved.

(Embodiment 2)
In the first embodiment, the cable holder 1 is configured using the sliding member 50 as described above. However, the sliding member 50 maintains the position of the placed cable 110 when the sliding member 50 slides. There is no particular limitation as long as the sliding means for ensuring the relative movement of the sliding member 50 is provided. For example, you may comprise the cable holder 1 using the sliding member shown in FIG.

  As shown in FIG. 8, the sliding member 50 </ b> A is formed of a plate-like member, and a through hole 51 is provided at the right end portion in the longitudinal direction to form a grip portion 55. On the upper part of the sliding member 50 other than the grip part 55, three rows of roller rows formed by arranging a plurality of spherical rollers 58A in a row in the longitudinal direction are provided, and a sliding means is formed. Since these spherical rollers 58A can rotate in any direction, the sliding member 50 can be moved in the width direction of the cable housing portion 100 without applying abnormal tension to the cable 110 more reliably than the sliding means constituted by ordinary rollers. Can be easily slid.

(Other aspects)
In Embodiment 1 and 2, although the cable holder 1 was demonstrated taking the cable accommodating part 100 in which the protrusion part 103 was provided as an example, the shape of a cable accommodating part is not limited to this. For example, you may make it attach the cable holder 1 to the cable accommodating part in which the protrusion part 103 is not provided, ie, a cable accommodating part of U-shaped cross section. Even if the cable holder 1 is attached to such a cable housing portion, the same effects as those of the first and second embodiments can be obtained. In this case, needless to say, it is not necessary to provide the engaging portion 13 in the cable holder 1.
