S2: Then hang the gabion hook on the hook (10), start the unwinding motor (11) to drive the worm (12) to mesh with the worm wheel (13), and drive the main rope roller (5) to wind up the main sling (6) through the worm wheel (13), so that the gabion is suspended and lifted, and is separated from direct contact with the ship hull. S4: While the main rope roller (5) is winding the main sling (6), the auxiliary rope roller (7) is driven by the synchronous pulley one (14), the synchronous pulley two (15) and the synchronous belt (16) to synchronously wind the auxiliary sling (8) to maintain the stability of the hoisting. S5: Based on the hoisting position of the gabion, start the electric slide rail (2) to drive the slide block (3) to move along the length direction of the gantry slide (1) to adjust the position of the gabion. At the same time, set the pressure sensor (24) to monitor the swaying of the gabion in real time and transmit the information to the controller (25). S6: Based on the information from the pressure sensor (24) received by the controller (25), start the regulating motor (21) to drive the regulating screw (20) to form a threaded connection with the regulating screw groove (22), push the L-shaped regulating rod (18) and the regulating wheel (19) to move along the regulating slide (17), adjust the fulcrum of the auxiliary sling (8), and improve the hoisting stability; S7: When the gabion is properly positioned, the main rope roller (5) is driven in the reverse direction to unwind the main sling (6), while the auxiliary rope roller (7) unwinds the auxiliary sling (8) synchronously, maintaining the tension of the auxiliary sling (8) and causing the hook (10) to carry the gabion along the length of the main sling (6) to sink to the bottom of the water, thus completing the sinking process.
