Abstract

PURPOSE:To hold a cable safely and securely by having a means, which installs a wedge-type holding tooth so that it may slide on a base, a means, which fixes the other end each of a first rope system and a second rope system to the hull, and a means, which adds tension to said first rope system. CONSTITUTION:A cable holder 20 is installed on the hull so that the cable 12 may be positioned between holding teeth 12, and the base 24 is shifted by operating a lever block 36. The wedge-type holding teeth 22 are detained by a rope system 30. Accordingly, the holding teeth 22 press the cable 12, being shut in by a columnar roller 26. After the cable 12 is held by this holder 20, the cable retention by a cutting/holding-type grappling machine can be released. Hereby, the tension Ts on sea side of the cable shifts to this holder 20, and pressure Ps arises in the holding tooth 22 anew.

As shown in FIG. 2 (AXB), a cable retainer is installed on the ship so that the cable 12 is positioned between the retaining teeth 22, and the lever block 36 is operated to move the platform 24 in the direction of the arrow 38. . The wedge-shaped retaining tooth 22 is a rope type 3
Since the cable 1 is held by the stopper 28 by the cylindrical roller 26, the opposing retaining teeth 22 are squeezed toward the center by the movement of the platform 24.
Press 2. The pressing force P generated on the holding teeth 22 is given by the first equation with respect to the tension T given by the lever block 36, if losses due to friction of rollers etc. are ignored.

After the cable 12 is held by the holder 2o,
Since it is not necessary to hold the cable by the cutting and holding type line probe 16 shown in FIG. 1, the cable holding by this can be released. As a result, the tension Ts on the sea side of the cable is transferred to the main retainer 20, and a new pressing force Ps is thereby generated on the retaining teeth 22. The relationship between Ts and Ps is also expressed by the second equation similarly to the first equation.

4) (Example 2) FIG. 3 shows a second example according to the present invention. The difference between Embodiment 2 and Embodiment 1 shown in FIG. By winding the cable with a winding device 44 fixed to the stand 24, the cable is pressed and held by the wedge-shaped holding teeth 22. Here, when tension is applied to the cable system 34 by the lever block 36, the tension applied to the submarine cable is gradually transferred from the cutting and holding type probe 16 to the main holder 40, and finally, the tension is applied to the submarine cable. The tension applied to the line machine 16 becomes zero, and the cable is completely held by the main holder 40.
