Detailed Description
The utility model will be further described with reference to the following specific embodiments.
As shown in fig. 1, 2 and 3, the optical cable mounting fixture of the present embodiment includes a wire storage ring 1, a first wire pressing plate 2, a second wire pressing plate 3, a mounting ring 4 and a stopper 5. The wire storage ring 1 is hollow and cylindrical, and the soft optical cable can be wound on the peripheral wall of the wire storage ring 1. The wire storage ring 1 is made of hard materials, and the wire storage ring 1 of the embodiment is an iron cylinder. The first line ball board 2 and the second line ball board 3 detachably set up on storing up wire loop 1, and on line loop 1 outer wall was stored up along circumference interval distribution to first line ball board 2 and second line ball board 3, first line ball board 2 and the second line ball board 3 of this embodiment all set up along storing up the axial of wire loop 1's strip shaped plate. Optionally, the first wire pressing plate 2 and the second wire pressing plate 3 of the present embodiment are symmetrically disposed on two sides of the axis of the wire storage ring 1. The limiting ring 4 is arranged on the first line pressing plate 2.
The first wire pressing plate 2 and the second wire pressing plate 3 of the present embodiment are connected to the wire storage ring 1 by threaded fasteners such as bolts, nuts, and the like. Through holes (not shown) for the bolts 7 to pass through are processed on the first line pressing plate 2 and the second line pressing plate 3, for example, a through hole is respectively arranged at two ends of the first line pressing plate 2 and the second line pressing plate 3, and the through holes for the bolts 7 to pass through are also arranged at corresponding positions of the line storage ring 1. After penetrating through the through holes of the first line pressing plate 1 and the line storage ring 1, the bolt 7 is matched with the nut 8, so that the first line pressing plate 2 is installed on the line storage ring 1. Similarly, after the bolt 7 passes through the second wire pressing plate 3 and the through hole on the wire storage ring 1, the bolt is matched with the nut 8, so that the first wire pressing plate 3 is mounted on the wire storage ring 1. After the first wire pressing plate 2 and the second wire pressing plate 3 are installed, gaps are reserved between the first wire pressing plate 2 and the outer wall of the wire storage ring 1 and between the second wire pressing plate 3 and the outer wall of the wire storage ring 1, and an optical cable wound on the wire storage ring 1 passes through the gaps between the wire pressing plate and the wire storage ring and is positioned between the wire pressing plate and the wire storage ring 1. The gap between the first wire pressing plate 2 and the wire storage ring 1 is equal to the gap between the second wire pressing plate 3 and the wire storage ring 1.
The stopper 5 is located between the first line pressing plate 2 and the line storage ring 1, and the stopper 5 is used for limiting the optical cable wound on the line storage ring 1 and preventing the optical cable from being displaced in the axial direction of the line storage ring 1 during overhead so as to change the stress center of the mounting clamp. The limiting block 5 can be fixed with the first line pressing plate 2 and is arranged on the first line pressing plate 2. The stopper 5 may be a hard rubber block. The thickness of the limiting block 5 is slightly larger than the outer diameter of the optical cable, for example, the thickness of the limiting block 5 is 0.5-1 mm larger than the outer diameter of the optical cable, so that the first line pressing plate 2 can play a certain role in pressing the optical cable and cannot crush the optical cable. When the optical cable is wound, a certain number of turns of the optical cable are wound according to the requirement, for example, 5 turns of the optical cable are wound on the wire storage ring 1, and since the optical cable is not completely wound on the whole wire storage ring 1, the limiting block 5 needs to be arranged to limit the optical cable storage ring 1 axially, in a specific embodiment, the length of the limiting block 5 (the dimension of the limiting block in the axial direction of the wire storage ring) can be 1/3 to 1/2 of the length of the first wire pressing plate 2 (the dimension of the first wire pressing plate in the axial direction of the wire storage ring).
Further optionally, since the mounting ring 4 is to be installed on the first wire pressing plate 2, the first wire pressing plate 2 is to bear a certain overhead tension, and the thickness of the first wire pressing plate 2 is greater than that of the second wire pressing plate 3, so that the first wire pressing plate has better structural strength to bear the overhead high tension.
In order to prevent the second crimp plate 3 from being crimped onto the optical cable to cause deformation of the optical cable, it is preferable that a soft cushion pad 6 is provided on the inner side surface of the second crimp plate 3 (the side surface of the second crimp plate 3 opposite to the wire storage ring 1). The soft cushion pad 6 is softer than the hardness of the optical cable, for example, EVA material softer than the hardness of the optical cable can be used. Through setting up blotter 6, both can make second line ball board 3 push down the optical cable, make the optical cable be difficult for skidding, it is not hard up, prevent that the optical cable from skidding, not hard up lead to difficult control space between air, can avoid second line ball board 3 to directly press on the optical cable again and lead to the optical cable to warp. In a specific embodiment, the gap between the buffer pad 6 and the wire storage ring 1 is slightly smaller than the outer diameter of the optical cable, e.g. the gap between the buffer pad 6 and the wire storage ring 1 is 1 mm-2 mm smaller than the outer diameter of the optical cable.
Fig. 4 is a schematic view of a structure for laying an optical cable using the optical cable mounting jig of the present utility model. As shown in fig. 4, the aerial structure for optical cable of the present utility model comprises an optical cable mounting fixture 10 and a resistance Zhang Dagan, when an optical cable is laid, after the optical cable is wound on the wire storage ring 1 for a certain number of turns, the optical cable mounting fixture 10 wound with the optical cable is mounted on the resistance Zhang Dagan 11 with proper aerial spacing, and the resistance Zhang Dagan can be a telegraph pole, an iron tower, a tree, a wall body, a bridge, etc. The cable mounting clamp 10 is mounted on the Zhang Dagan resistant cable through a mounting ring.
As shown in fig. 5, during winding, the optical cable 20 is wound around the wire storage ring 1 clockwise from the position of the first wire pressing plate 2, the optical cable passes through the gap between the first wire pressing plate and the second wire pressing plate and the wire storage ring 1, the last round of optical cable ends at the position of the second wire pressing plate 2, and when the optical cable is wound to the last round, the optical cable is wound to the outer side of the second wire pressing plate 2. After the optical cable winding is completed, the optical cable of the last circle is aligned with the mounting ring 4 and is blocked by the limiting block 5.
In order to facilitate the installation of the optical cable mounting clamp and the adjustment of the tension, preferably, a metal ring chain is arranged on the Zhang Dagan resistance, the metal ring chain is wound on a telegraph pole or a trunk, the mounting ring of the mounting clamp is firstly hung on the ring of the ring chain through a gourd-shaped movable opening hanging buckle, then the position of the optical cable mounting clamp is adjusted according to the tension requirement, the optical cable mounting clamp is buckled on a proper ring, and the installation of the optical cable mounting clamp is completed. When the optical cable is wound, the optical cable mounting clamp is taken down from the Zhang Dagan resistance, so that the optical cable mounting clamp is convenient and quick, high in efficiency, and free of erecting steel ropes during laying, working procedures are reduced, and material cost is also reduced.
Various other corresponding changes and modifications will occur to those skilled in the art from the foregoing description and the accompanying drawings, and all such changes and modifications are intended to be included within the scope of the present utility model as defined in the appended claims.
