Description

Technical Field

[0001] The utility model relates to the technical field of underwater installation of large-scale twist king blocks, in particular to an underwater installation device for large-scale twist king blocks. Background Art

[0002] Large twist blocks are a type of face protection blocks, generally placed on the outermost layer of a breakwater to protect the breakwater by weakening the impact of waves. As a unique large-scale artificial concrete structure, large twist blocks utilize their own weight and the unique twisted-shaped structure of the blocks to dissipate energy and prevent waves. They can effectively block tides, prevent waves, and protect hydraulic structures on coasts, islands, and estuaries, playing an important role in coastal protection. During the installation of large twist blocks, an installation device is required. Existing installation devices are basically crane-controlled slings to lift and install large twist blocks. However, existing slings are basically moved to the top of the large twist blocks by the crane, and then the staff need to put a lifting rope on the surface of the large twist blocks to lift them. When the crane then sends the large twist blocks underwater, the diver needs to remove the lifting rope from the surface of the large twist blocks. This process is time-consuming and labor-intensive, and it is difficult to realize the function of automatically clamping and unhooking the large twist blocks, which indirectly prolongs the working time of the staff and indirectly affects the work efficiency of the staff.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1-4 The utility model provides a technical solution: an underwater installation device for a large twisting king block, including a cross beam 1, a through groove 2 is opened on the outer side of the cross beam 1 to prevent collision with the cross beam 1, a fixed shaft 3 is fixedly inserted into the inner wall of the cross beam 1, and a transmission rod 4 is movably sleeved on the outer surface of the fixed shaft 3, and the transmission rod 4 is located inside the through groove 2, so that the transmission rod 4 can run inside it. The top of the transmission rod 4 is fixedly inserted with a short shaft 5, and the outer surface of the short shaft 5 is movably sleeved with a connecting block 6. The inner end of the connecting block 6 is fixedly connected with a hydraulic cylinder 7, which is connected to an external hydraulic pump. The hydraulic cylinder 7 can provide power to the clamping rod 8 through the transmission rod 4, and the clamping rod 8 is fixedly connected to the bottom of the outer surface of the transmission rod 4. The extension or shortening of the output end of the hydraulic cylinder 7 can indirectly drive the clamping rod 8 to move inward or outward, so that the device can automatically clamp and unhook the large twisting king block.

[0023] In order to improve the clamping effect of the clamping rod 8 on the large twist king block, the utility model has an anti-skid layer 9 movably sleeved on the outer side of the clamping rod 8. The anti-skid layer 9 is provided in two groups. The anti-skid layer 9 indirectly increases the friction between the clamping rod 8 and the large twist king block, preventing the large twist king block from slipping, thereby improving the clamping effect of the clamping rod 8 on the large twist king block.

[0024] In order to facilitate the user to replace the anti-slip layer 9, the utility model provides a through hole 10 on the outer side of the anti-slip layer 9, and a through hole 2 11 on the outer side of the clamping rod 8. Bolts 12 are inserted into the through hole 10 and the through hole 2 11, and the rear side of the outer surface of the bolt 12 is threadedly connected with a nut 13. The anti-slip layer 9 will be damaged after long-term use. Then the staff will rotate the nut 13 out of the surface of the bolt 12, and then pull the bolt 12 out of the through hole 10 and the through hole 2 11, releasing the fixation between the anti-slip layer 9 and the clamping rod 8. At this point, the disassembly of the damaged anti-slip layer 9 is completed, and conversely, a new anti-slip layer 9 can be installed.

[0025] In order to facilitate the staff to quickly connect the device with the crane, the utility model has a connecting plate 14 fixedly connected to the middle of the upper surface of the beam 1, and a connecting hole 15 is opened on the top of the outer side of the connecting plate 14. The staff passes the hook on the crane through the inside of the connecting hole 15 and fixes it. At this point, the connection between the device and the crane is completed. This process has fewer operating steps, saves time and effort, and is convenient for the staff to quickly connect the device to the crane.

[0026] In order to improve the stability of the connection between the connecting plate 14 and the crossbeam 1, the utility model has a connecting frame 16 fixedly sleeved on the bottom of the outer side of the connecting plate 14. The lower surface of the connecting frame 16 is fixedly connected to the upper surface of the crossbeam 1. The connecting frame 16 increases the connection area between the connecting plate 14 and the crossbeam 1, thereby improving the stability of the connection between the connecting plate 14 and the crossbeam 1.

[0027] In order to ensure the stability of the fixed shaft 3 when being used, the present invention has connecting rings 17 fixedly sleeved on both the front and rear sides of the outer surface of the fixed shaft 3. The outer side surface of the connecting ring 17 is fixedly connected to the inner wall of the through groove 2. The connecting ring 17 increases the connection area between the fixed shaft 3 and the crossbeam 1, thereby ensuring the stability of the fixed shaft 3 when being used.

[0028] The electrical components mentioned in this article are all connected to an external main controller and 220V AC power, and the main controller can be a conventional known device that performs control such as a computer.

[0029] Then the hydraulic cylinder 7 is closed so that the clamping rod 8 stops moving, and the clamping of the large twisting block is completed. Then the staff controls the crane to lift the device and the large twisting block above the water surface, and then places the large twisting block on the bottom of the water, and then works. When the hydraulic cylinder 7 is started again, the output end of the hydraulic cylinder 7 is retracted inwardly, which can indirectly move the clamping rod 8 outward until the clamping rod 8 and the anti-skid layer 9 are released from contact with the surface of the large twist king block, thereby releasing the clamping of the large twist king block. At this point, the lifting and underwater installation of the large twist king block are completed. This process reduces the participation of other staff members, saves time and effort, and speeds up work efficiency. When the anti-skid layer 9 is damaged after long-term use, the staff member controls the wrench tool to tighten the nut 13 until the nut 13 is rotated out of the outer surface of the bolt 12, contacting the connection between the bolt 12 and the nut 13, and then withdraws the bolt 12 from the inside of the through hole 10 and the through hole 2 11, releasing the fixation between the anti-skid layer 9 and the clamping rod 8, and then the staff member can remove the anti-skid layer 9. At this point, the removal of the damaged anti-skid layer 9 is completed, and vice versa, a new anti-skid layer 9 can be installed on the surface of the clamping rod 8, which is convenient for the staff to replace the anti-skid layer 9.
