The top and bottom of the frame 1 are provided with wing plates 2. The frame 1 is provided with a limiting and launching component.

[0038] Mounting base 4 is symmetrically fixedly installed at the bottom of the lower wing plate 2. The base plate 3 is rotatably installed inside the mounting base 4 via a pivot. The crossbeam 5 is fixedly installed at the bottom of the base plate 3. The first lifting lugs 6 are symmetrically fixedly installed on the crossbeam 5. The second lifting lugs 7 are fixedly installed at the top four corners of the upper wing plate 2. The main wire rope 8 is connected to the four first lifting lugs 6 via a hanging ring. The auxiliary wire rope 9 is connected to the four second lifting lugs 7 via a hanging ring. The lateral limiting component is set inside the frame 1 and is used to laterally limit the flexible gabion. One end of the traction rope 10 is connected to the first lifting lug 6.

[0039] In use, the flexible gabion net is placed in the frame body 1, then the flexible gabion net is filled with pebbles / stone blocks, after filling, the flexible gabion net is covered, one end of the main steel wire rope 8 and one end of the auxiliary steel wire rope 9 are connected with the hoisting device, the hoisting device cooperates with the main steel wire rope 8, the first lifting lug 6, the cross beam 5 and the bottom plate 3 to hoist the frame body 1 and the flexible gabion inside the frame body 1, at this time, the auxiliary steel wire rope 9 is not stressed, the angle of the lifting tool is controlled by manually cooperating with the traction rope 10, after reaching the specified position, the main steel wire rope 8 is lowered, at this time, the frame body 1 is supported by the auxiliary steel wire rope 9 cooperating with the second lifting lug 7 and the wing plate 2, the main steel wire rope 8 is lowered, under the action of gravity, the bottom plate 3 rotates downward to open, after the bottom plate 3 opens vertically downward, the lowering of the main steel wire rope 8 is stopped, at this time, the main steel wire rope 8 is in a tense state, the flexible gabion falls downward, at this time, the lateral limiting assembly and the bottom plate 3 cooperate to limit the flexible gabion, so that the internal flexible gabion does not move to another place under the impact of water flow during falling, and finally falls to the required area, through the double adjustment mechanism of the main steel wire rope 8 hoisting + manual angle control of the traction rope 10, the underwater posture of the lifting tool can be flexibly adjusted, the frame body 1 provides a stable operation platform during the stone filling stage, without the need for additional binding and fixing, effectively improving the stone filling speed, through the cooperation of the frame body 1, the bottom plate 3, the side plate 14 and the extension plate 17, the deformation of the flexible gabion during filling, hoisting and launching can be effectively constrained, so that the flexible gabion can be guaranteed to be launched to the required area.

[0040] As shown in Figure 1 , Figure 4 , Figure 5 , the lateral limiting assembly comprises a side plate 14, a vertical groove 15, a limiting block 16, an extension plate 17 and a reset assembly.

[0041] The inner wall of the frame body 1 is symmetrically provided with notches, the side plate 14 is arranged in the corresponding notch, the vertical groove 15 is symmetrically arranged on the inner wall of the notch, the limiting block 16 is slidingly installed in the vertical groove 15, the limiting block 16 is fixedly connected with the side plate 14, the extension plate 17 is symmetrically slidingly installed on the side plate 14, and the reset assembly is connected with the extension plate 17 and used for driving the extension plate 17 to reset.

[0042] With the gradual opening of the bottom plate 3, at this time, the flexible gabion and the side plate 14 are lowered under the action of gravity, in the process of lowering, the flexible gabion is limited by the side plate 14, the extension plate 17 and the bottom plate 3, so that the flexible gabion is not moved to another place by the water flow, when the bottom plate 3 is pulled upward to close, the bottom plate 3 extrudes the extension plate 17 to make the extension plate 17 enter the side plate 14, so that the bottom plate 3 can normally rotate, finally, the bottom plate 3 abuts against the bottom of the side plate 14 to push the side plate 14 upward, finally, the side plate 14 resets, and the reset assembly drives the extension plate 17 to reset.

[0043] As shown in Figure 4 , the reset assembly comprises a push block 18 and a spring 19.

[0044] Both sides of the side plate 14 are provided with a receiving groove, the bottom of the receiving groove is open, the extension plate 17 is located in the receiving groove, the top wall of the receiving groove is provided with a horizontal groove, the push block 18 is slidingly arranged in the horizontal groove, the push block 18 is fixedly connected with the extension plate 17, and the spring 19 is fixedly connected with the inner wall of the horizontal groove away from one side of the vertical groove 15.

[0045] When the extension plate 17 is extruded by the bottom plate 3, the push block 18 moves to compress the spring 19 to deform, so that the extension plate 17 is received in the receiving groove, and when the bottom plate 3 resets, the spring 19 resets at this time, so that the extension plate 17 is reset by cooperating with the push block 18.

[0046] The bottom of the side plate 14 is attached to the top of the bottom plate 3, and when the bottom plate 3 rotates to the vertical state, the side plate 14 moves with the limiting block 16 to abut against the bottom wall of the vertical groove 15, and at this time, the bottom of the side plate 14 is located above the bottom of the bottom plate 3.

[0047] So as to ensure that the bottom plate 3 can push the bottom of the side plate 14 upward to reset when rotating to reset.

[0048] As shown in Figures 4 to 7 , the top of the bottom plate 3 is provided with a sliding assembly, the sliding assembly can reduce the wear of the flexible gabion on the top of the bottom plate 3, and the sliding assembly comprises: a side frame 20, a guide roller 21 and a transmission belt 22.

[0049] The side frame 20 is symmetrically and fixedly installed on the top of the bottom plate 3, the guide roller 21 is equidistantly and rotatably installed between the pair of side frames 20, and the transmission belt 22 is sleeved outside the plurality of guide rollers 21.

[0050] When the flexible gabion descends, it moves along the surface of the transmission belt 22, so that the transmission belt 22 and the guide roller 21 rotate, and the flexible gabion moves synchronously with the transmission belt 22, which greatly reduces the wear of the flexible gabion on the bottom plate 3 and prolongs the service life of the bottom plate 3.

[0051] As shown in Figure 1 and Figure 9 , the outer side of the frame body 1 is fixedly installed with a mounting bracket 11 corresponding to the first lifting lug 6, a guide wheel 12 is rotatably installed in the mounting bracket 11, and the main steel wire rope 8 is connected with the first lifting lug 6 through the guide wheel 12 and the mounting bracket 11.

[0052] The guide wheel 12 guides to prevent the whole lifting appliance from deviating laterally, improves the lifting stability, cooperates with the double adjustment mechanism of the main steel wire rope 8 lifting + the manual control angle of the traction rope 10 to realize the accurate placement of the gabion at the specified underwater position.

[0053] As shown in Figure 1 , a limiting hoop 23 is equidistantly and fixedly installed on the outside of the frame body 1 from top to bottom.

[0054] The limiting hoop 23 improves the anti-deformation ability of the frame body 1.

[0055] The frame 1 has a partition 13 inside. The partition 13 is placed inside the gabion mesh, and then pebbles / blocks are filled inside the gabion mesh. After filling, the partition 13 is removed and the gabion is covered. The partition 13 is used to restrict the flexible gabion mesh so that it does not deform during filling.

[0056] like Figure 6 As shown, the conveyor belt 22 is specifically configured as a steel conveyor belt.

[0057] This allows the conveyor belt 22 to withstand the compression of the gabion, ensuring that the conveyor belt 22 will not be damaged.

[0058] By adjusting the size of the partition 13 and the specifications of the lifting frame 1, it can be adapted to flexible gabions with different volumes and partition structures of 1-5m³, and is compatible with various filling types such as pebbles and boulders. The lifting device is highly versatile with conventional lifting equipment such as cranes, and does not require additional equipment modification. It can be widely used in various underwater protection projects such as inland waterways, coastal ports, and reservoir dams. Its application scope covers a variety of scenarios of traditional lifting devices, and its adaptability is better.

[0059] Working principle: In use, a flexible gabion mesh is placed inside the frame 1, and the partition 13 is placed inside the gabion mesh. Then, pebbles / block stones are filled into the gabion mesh. After filling, the partition 13 is removed, and the gabion is covered. One end of the main wire rope 8 and one end of the auxiliary wire rope 9 are connected to the lifting equipment. The lifting equipment, in conjunction with the main wire rope 8, the first lifting lug 6, the crossbeam 5, and the bottom plate 3, lifts the frame 1 and the flexible gabion inside. During lifting, the auxiliary wire rope 9 is not under stress. The angle of the lifting device is controlled manually with the traction rope 10. After reaching the designated position, the main wire rope 8 is lowered. At this time, the auxiliary wire rope 9, in conjunction with the second lifting lug 7 and the wing plate 2, supports the frame 1. As the main wire rope 8 moves down, the bottom plate 3 rotates downward and opens under the action of gravity. After the bottom plate 3 opens to a vertical position, the downward movement of the main wire rope 8 is stopped. As the main steel wire rope 8 is taut, the flexible gabion falls downwards. As the bottom plate 3 gradually opens, the flexible gabion and side plate 14 descend under the action of gravity. During the descent, the side plate 14, extension plate 17, and bottom plate 3 restrict the flexible gabion from being affected by the water flow and moving elsewhere. Finally, it falls to the required area. Through the dual adjustment mechanism of the main steel wire rope 8 lifting and the traction rope 10 manually controlling the angle, the underwater posture of the lifting device can be flexibly adjusted. During the gabion filling stage, the frame 1 provides a stable working platform without the need for additional binding and fixing, which effectively improves the stone filling speed. Through the cooperation of the frame 1, bottom plate 3, side plate 14, and extension plate 17, the deformation of the flexible gabion during filling, lifting, and launching can be effectively constrained, ensuring that the flexible gabion is deployed to the required area.

[0060] The flexible gabion moves along the surface of the conveying belt 22 when descending, so that the conveying belt 22 and the guide roller 21 rotate, the flexible gabion moves synchronously with the conveying belt 22, the abrasion of the flexible gabion to the bottom plate 3 is greatly reduced, and the service life of the bottom plate 3 is prolonged;

[0061] Pulling the main steel wire rope 8 to ascend and reset enables the first lifting lug 6 to pull the cross beam 5 and the bottom plate 3 to rotate upward, the bottom plate 3 extrudes the extension plate 17 to make it enter the side plate 14, so that the bottom plate 3 can rotate normally, when the extension plate 17 is extruded, the push block 18 moves to compress the spring 19 to deform, finally the bottom plate 3 abuts against the bottom of the side plate 14 to push the side plate 14 to ascend, finally the side plate 14 resets, the bottom plate 3 resets, at this time, the spring 19 resets, so that the extension plate 17 is reset by the push block 18.

[0062] The above embodiments are only used to illustrate the technical solutions of the present application, but not limit it.
