Description

Technical Field

[0001] This invention belongs to the field of water conservancy engineering construction technology, and specifically relates to a lifting device for underwater hoisting of flexible gabions. Background Technology

[0002] In underwater protection engineering construction, flexible gabions are widely used in foundation protection, slope reinforcement, and other scenarios due to their excellent permeability, integrity, and erosion resistance. The specific operation involves filling the flexible gabion mesh with stones and then hoisting the filled mesh to the required area for use.

[0003] However, existing flexible gabions are prone to deformation during underwater construction, and their placement is inaccurate due to water flow. They are also prone to deformation when filling on land.

[0004] Therefore, it is necessary to invent a lifting device for underwater hoisting of flexible gabions to solve the above problems. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a lifting device for underwater hoisting of flexible gabions, thereby resolving the issues raised in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A lifting device for underwater lifting of flexible gabions includes: a frame, with wing plates at the top and bottom of the frame, and a limiting and launching component on the frame, which can limit and launch the flexible gabion located in the frame so that the flexible gabion can fall into the required launching area. The limiting and launching assembly includes: a base plate, a mounting base, a crossbeam, a first lifting lug, a second lifting lug, a main steel wire rope, a secondary steel wire rope, a traction rope, and a lateral limiting assembly; The mounting base is symmetrically fixedly installed at the bottom of the lower wing plate. The base plate is rotatably installed inside the mounting base via a pivot. The crossbeam is fixedly installed at the bottom of the base plate. The first lifting lugs are symmetrically fixedly installed on the crossbeam. The second lifting lugs are fixedly installed at the top four corners of the upper wing plate. The main steel wire rope is connected to the four first lifting lugs. The auxiliary steel wire rope is connected to the four second lifting lugs. The lateral limiting component is located inside the frame and is used to laterally limit the flexible gabion. One end of the traction rope is connected to the first lifting lug.

[0007] Furthermore, the lateral limiting component includes: a side plate, a vertical groove, a limiting block, an extension plate, and a reset component; The inner wall of the frame is symmetrically provided with recesses, the side plates are set in the corresponding recesses, the vertical grooves are symmetrically provided on the inner wall of the recesses, the limiting blocks are slidably installed in the vertical grooves, the limiting blocks are fixedly connected to the side plates, the extension plates are symmetrically slidably installed on the side plates, and the reset assembly is connected to the extension plates for driving the extension plates to reset.

[0008] Furthermore, the reset assembly includes: a push block and a spring; Both sides of the side plate are provided with receiving grooves, the extension plate is located in the receiving grooves, the top wall of the receiving groove is provided with a horizontal groove, the push block is slidably disposed in the horizontal groove, the push block is fixedly connected to the extension plate, and the spring fixes the side of the push block away from the vertical groove to the inner wall of the horizontal groove.

[0009] Furthermore, the bottom of the side plate is attached to the top of the bottom plate. When the bottom plate is rotated to a vertical position, the side plate, along with the limiting block, moves to contact the bottom wall of the vertical groove. At this time, the bottom of the side plate is located above the bottom of the bottom plate.

[0010] Furthermore, a sliding component is provided on the top of the base plate, which can reduce the wear of the flexible gabion on the top of the base plate.

[0011] Furthermore, the sliding assembly includes: a side frame, guide rollers, and a conveyor belt; The side frames are symmetrically fixedly installed on the top of the base plate, the guide rollers are equidistantly rotatably installed between a pair of side frames, and the conveyor belt is sleeved on the outside of the multiple guide rollers.

[0012] Furthermore, a mounting bracket corresponding to the first lifting lug is fixedly installed on the outer side of the frame, and a guide wheel is rotatably installed inside the mounting bracket. The main steel wire rope passes through the guide wheel and the mounting bracket and connects to the first lifting lug.

[0013] Furthermore, limit clamps are fixedly installed at equal intervals from top to bottom on the outside of the frame.

[0014] Furthermore, the frame is provided with a partition inside, which is used to restrict the flexible gabion mesh so that it does not deform during filling.

[0015] Furthermore, the conveyor belt is specifically configured as a steel conveyor belt.

[0016] The technical effects and advantages of this invention are as follows: 1. The frame of this invention is welded from rectangular steel plates and channel steel, and equipped with limiting hoops and upper and lower wing plates. It has strong overall rigidity and outstanding load-bearing capacity. Through the dual adjustment mechanism of main wire rope lifting and manual angle control by traction rope, the underwater posture of the lifting equipment can be flexibly adjusted. During the gabion filling stage, the frame 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, bottom plate, side plate and extension plate, the deformation of the flexible gabion during filling, lifting and launching can be effectively restrained, and the displacement of the gabion due to water flow can be avoided, so as to ensure that the flexible gabion can be deployed to the required area. 2. The sliding component of this invention greatly reduces the wear on the bottom plate of the flexible gabion and extends the service life of the bottom plate. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0020] This invention provides a lifting device for underwater hoisting of flexible gabions, such as... Figures 1 to 9 As shown, it includes: a frame 1, which is made of rectangular steel plates and channel steel welded together. The outer side of the frame 1 is equidistant. 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. The limiting and launching component can limit and launch the flexible gabion located in the frame 1, so that the flexible gabion can fall into the required launching area. The limiting and deployment components include: base plate 3, mounting base 4, crossbeam 5, first lifting lug 6, second lifting lug 7, main steel wire rope 8, auxiliary steel wire rope 9, traction rope 10, and lateral limiting components; 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.

[0021] In use, a flexible gabion mesh is placed inside the frame 1, and then filled with pebbles / blocks. After filling, the flexible gabion mesh is sealed. 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 base plate 3, lifts the frame 1 and the flexible gabions inside. During lifting, the auxiliary wire rope 9 is not under stress, and 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 downward, the base plate 3 rotates downward and opens under the action of gravity. After the base plate 3 opens to a vertical position, the main wire rope 8 is stopped. As the gabion descends, the main steel wire rope 8 is taut, and the flexible gabion falls downwards. At this time, the lateral limiting components and the bottom plate 3 work together to limit the flexible gabion, so that the flexible gabion inside will not be moved to another place due to the impact of the water flow during the fall, and finally fall 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 equipment 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, the bottom plate 3, the side plate 14, and the extension plate 17, the deformation of the flexible gabion during the filling, lifting and launching process can be effectively restrained, so as to ensure that the flexible gabion is deployed to the required area.

[0022] like Figure 1 , Figure 4 , Figure 5 As shown, the lateral limiting assembly includes: a side plate 14, a vertical groove 15, a limiting block 16, an extension plate 17, and a reset assembly; The inner wall of the frame 1 has symmetrically opened recesses, the side plate 14 is set in the corresponding recesses, the vertical groove 15 is symmetrically opened on the inner wall of the recesses, the limiting block 16 is slidably installed in the vertical groove 15, the limiting block 16 is fixedly connected to the side plate 14, the extension plate 17 is symmetrically slidably installed on the side plate 14, and the reset assembly is connected to the extension plate 17 for driving the extension plate 17 to reset.

[0023] As the bottom plate 3 gradually opens, the flexible gabion and side plate 14 descend under the action of gravity. During the descent, the flexible gabion is prevented from being moved elsewhere by the water flow by the side plate 14, extension plate 17 and bottom plate 3. When the bottom plate 3 is pulled upward to close, the bottom plate 3 squeezes the extension plate 17 and causes it to retract into the side plate 14, allowing the bottom plate 3 to rotate normally. Finally, the bottom plate 3 and the bottom of the side plate 14 come into contact and push the side plate 14 to rise. Finally, the side plate 14 is reset, and the reset component drives the extension plate 17 to reset.

[0024] like Figure 4 As shown, the reset assembly includes: push block 18 and spring 19; Both sides of the side plate 14 are provided with receiving grooves, the bottom of the receiving grooves is open, the extension plate 17 is located in the receiving grooves, the top wall of the receiving grooves is provided with a horizontal groove, the push block 18 is slidably disposed in the horizontal groove, the push block 18 is fixedly connected to the extension plate 17, and the spring 19 fixes the side of the push block 18 away from the vertical groove 15 to the inner wall of the horizontal groove.

[0025] When the extension plate 17 is pressed by the base plate 3, it will move along with the push block 18 to compress the spring 19 and deform it, so that the extension plate 17 is put into the receiving groove. When the base plate 3 is reset, the spring 19 is reset, so that the push block 18 pushes the extension plate 17 to reset.

[0026] The bottom of the side plate 14 is attached to the top of the base plate 3. When the base plate 3 is rotated to a vertical position, the side plate 14 moves with the limiting block 16 to abut against the bottom wall of the vertical groove 15. At this time, the bottom of the side plate 14 is located above the bottom of the base plate 3.

[0027] This ensures that when the base plate 3 rotates and resets, it can push the bottom of the side plate 14 upwards to reset it.

[0028] like Figures 4 to 7 As shown, a sliding assembly is provided on the top of the base plate 3. The sliding assembly can reduce the wear of the flexible gabion on the top of the base plate 3. The sliding assembly includes: side frame 20, guide roller 21, and conveyor belt 22. The side frames 20 are symmetrically fixedly installed on the top of the base plate 3, the guide rollers 21 are equidistantly rotated between a pair of side frames 20, and the conveyor belt 22 is sleeved on the outside of the multiple guide rollers 21.

[0029] As the flexible gabion descends, it moves along the surface of the conveyor belt 22, causing the conveyor belt 22 and guide roller 21 to rotate. The flexible gabion moves synchronously with the conveyor belt 22, which greatly reduces the wear of the flexible gabion on the base plate 3 and extends the service life of the base plate 3.

[0030] like Figure 1 and Figure 9 As shown, a mounting bracket 11 corresponding to the first lifting lug 6 is fixedly installed on the outer side of the frame 1. A guide wheel 12 is rotatably installed inside the mounting bracket 11. The main steel wire rope 8 passes through the guide wheel 12 and the mounting bracket 11 and is connected to the first lifting lug 6.

[0031] The guide wheel 12 guides the loaders to prevent lateral shift and improves lifting stability. Combined with the dual adjustment mechanism of the main wire rope 8 for lifting and the traction rope 10 for manual angle control, the gabion can be accurately deployed to the designated underwater position.

[0032] like Figure 1 As shown, limit clamps 23 are fixedly installed at equal intervals from top to bottom on the outside of frame 1.

[0033] The limiting hoop 23 enhances the deformation resistance of the frame 1.

[0034] 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.

[0035] like Figure 6 As shown, the conveyor belt 22 is specifically configured as a steel conveyor belt.

[0036] This allows the conveyor belt 22 to withstand the compression of the gabion, ensuring that the conveyor belt 22 will not be damaged.

[0037] 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.

[0038] 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. When the flexible gabion descends, it moves along the surface of the conveyor belt 22, causing the conveyor belt 22 and guide roller 21 to rotate. The flexible gabion moves synchronously with the conveyor belt 22, which greatly reduces the wear of the flexible gabion on the base plate 3 and extends the service life of the base plate 3. Pulling the main steel wire rope 8 causes it to rise and reset, enabling it to work with the first lifting lug 6 to pull the crossbeam 5 and the base plate 3 to rotate upwards. The base plate 3 presses the extension plate 17, causing it to retract into the side plate 14, allowing the base plate 3 to rotate normally. When the extension plate 17 is pressed, it moves with the push block 18, compressing the spring 19 and causing it to deform. Finally, the bottom of the base plate 3 and the side plate 14 come into contact, pushing the side plate 14 to rise. Finally, the side plate 14 resets, the base plate 3 resets, and the spring 19 resets, allowing the push block 18 to push the extension plate 17 to reset.

[0039] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it.
