Cable bending-limiting laying device and laying method
Cable bending-limiting laying device and laying method
The cable laying method comprises the following steps that a linear cable is launched, after a semicircular cable arrives at the stern, the semicircular cable is installed in the groove of the bending limiting frame, and the accompanying binding rope is cut off. The crane drives the bending limiting frame to enter water and descend to the seabed, then the two unhooking devices are unhooked, and the bending limiting frame is flatly placed on the seabed. The position of the bending limiting frame is positioned through beacons, the position of the bending limiting frame is marked, the ship retreats to the corresponding position of the bending limiting frame, the crane drives the bending limiting frame to ascend through the hanging beam and the steel wire rope, the semicircular cable is separated from the bending limiting frame, and flat laying of the linear cable and the semicircular cable is completed. The cable bending limiting laying device is used for controlling the laying process of the semicircular cable, the semicircular cable is located in the groove, it can be ensured that the semicircular cable is flat, the semicircular cable is prevented from forming a small circle, the bending radius is prevented from being too small, the safety of the cable is ensured, the working water depth can be increased to 1000 m, and fault repair of the deeply-buried cable is facilitated.
一种电缆布放方法，包括以下步骤：直线电缆下水完成，半圆形电缆来到船尾之后，将半圆形电缆安装在所述限弯架的凹槽中，砍断所述陪绑绳。起重机带动限弯架入水下降至海底，然后将两个脱钩装置脱钩，限弯架平放在海床上。利用信标定位限弯架的位置，将限弯架的位置标注，船后退至限弯架的对应位置，利用起重机通过吊梁、钢丝绳带动限弯架上升，半圆形电缆脱离限弯架，完成直线电缆和半圆形电缆的平整布放。本发明利用电缆限弯布放装置对半圆形电缆的布放过程进行控制，半圆形电缆位于凹槽中，可以确保半圆形电缆平整，防止半圆形电缆打小圈，防止弯曲半径过小，保证电缆的安全，可以把作业水深提升到1000米，方便深埋电缆的故障修理。
