Description

Technical Field

[0001] This utility model relates to a floating crane device for assembling ship sections in a dock environment, and particularly to a floating crane device for assembling ship sections in a dock environment applied to the field of ship hoisting. Background Technology

[0002] In the dock operations of shipbuilding, the assembly of ship sections is a critical and complex process. As the core equipment for lifting ship sections, the performance of the floating crane directly affects the progress and quality of the project. However, there are still some shortcomings in the replacement of the hook components during the lifting process.

[0003] In existing technologies, hooks are mostly connected by bolts. When facing different lifting needs of different ship sections and needing to frequently change hook types, the process of disassembling and installing hooks may be cumbersome. Workers need to use a variety of tools such as wrenches and screwdrivers to complete the disassembly, which may not be efficient. At the same time, when floating cranes are used for lifting operations in humid environments for a long time, threaded hooks are prone to rust and seizing, which may make them difficult to remove quickly. The disassembly efficiency needs to be further improved. Utility Model Content

[0004] The technical problem that this utility model aims to solve in view of the above-mentioned prior art is that the hook assembly on the floating crane is difficult to disassemble quickly, resulting in low disassembly efficiency.

[0005] To address the aforementioned problems, this utility model provides a floating crane device for assembling ship sections in a dock environment, including a gantry mounted on a floating crane vessel, with a hook assembly connected to the gantry via a lifting rope. The hook assembly includes:

[0006] Symmetrically arranged connecting plates and threaded hooks;

[0007] Mounting plate, fixedly connected to the connecting plate;

[0008] Threaded block, sliding connection in the mounting plate;

[0009] The threaded hook is matched with the threaded block;

[0010] The pull rod is fixedly connected to the threaded block;

[0011] The first magnet is fixedly connected to the pull rod;

[0012] The second magnet is fixedly connected to the connecting plate;

[0013] The first and second magnets are attracted to each other.

[0014] In the aforementioned floating crane device for assembling ship sections, the threaded hooks in the hook assembly can be quickly replaced via the hook assembly.

[0015] As a further improvement of this application, a third magnet is fixedly connected to each of the two sets of threaded blocks, and the two sets of symmetrically arranged third magnets attract each other.

[0016] As a further improvement of this application, a first groove is provided on the mounting plate, and a first limiting block is slidably connected in the first groove. The first limiting block is fixedly connected to the bottom wall of the threaded block.

[0017] As a further improvement of this application, a second sliding groove is provided on the side wall of the mounting plate, and a second limiting block is slidably connected in the second sliding groove. The second limiting block is fixedly connected to the side wall of the threaded block.

[0018] As a further improvement to this application, mounting holes are provided on the pull rod.

[0019] As a further improvement to this application, anti-slip textures are provided on the inner wall of the mounting hole.

[0020] As a further improvement of this application, the pusher plate is an arc-shaped plate, and guide slopes are provided on both sides of the pusher plate.

[0021] In summary, this application's device eliminates the need for wrenches and other disassembly tools when disassembling threaded hooks. Workers can quickly separate the threaded block by simply pulling the lever outwards, allowing for rapid removal of the threaded hook. Furthermore, when the threaded hook and threaded block become stuck due to rust, the device's separation of the threaded block still enables the rapid removal of the rust-seized hook, thus improving disassembly efficiency.

[0032] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0033] Implementation method 1:

[0034] Figures 1-8 This invention illustrates a floating crane device for assembling ship sections in a dock environment. A jack 101 is installed on a floating crane vessel 1, and a hook assembly is connected to the jack 101 via a lifting rope 1011. The hook assembly includes:

[0035] The connecting plate 2 and the threaded hook 3 are symmetrically arranged;

[0036] Mounting plate 4 is fixedly connected to connecting plate 2;

[0037] Threaded block 6 is slidably connected in mounting plate 4;

[0038] The threaded hook 3 is matched with the threaded block 6;

[0039] Pull rod 5 is fixedly connected to threaded block 6;

[0040] The first magnet 502 is fixedly connected to the pull rod 5;

[0041] The second magnet 201 is fixedly connected to the connecting plate 2;

[0042] The first magnet 502 and the second magnet 201 are attracted to each other.

[0043] A third magnet 602 is fixedly connected to each of the two sets of threaded blocks 6, and the two sets of symmetrically arranged third magnets 602 attract each other.

[0044] It should be noted that both the first magnet 502 and the third magnet 602 are commercially available electromagnets.

[0045] When the threaded hook 3 needs to be replaced, the third magnet 602 is de-energized. At this time, the two sets of third magnets 602 will no longer attract each other. At this time, the staff pulls out the pull rod 5. The movement of the pull rod 5 will drive the threaded block 6 to move. The two sets of threaded blocks 6 will separate from each other. At this time, the thread groove on the threaded block 6 will not engage with the threaded teeth on the threaded hook 3. At this time, the staff can manually pull the threaded hook 3 outward to remove the threaded hook 3 from the mounting plate 4.

[0046] When disassembling the threaded hook 3, this device eliminates the need for wrenches and other disassembly tools. Workers can simply pull out the lever 5 to quickly separate the threaded block 6, allowing them to quickly remove the threaded hook 3. Furthermore, when the threaded hook 3 and threaded block 6 become stuck due to rust, the device can still quickly remove the stuck threaded hook 3 by separating the threaded block 6, thus improving disassembly efficiency.

[0047] When installing a new threaded hook 3, the worker can insert the threaded hook 3 into the mounting plate 4 and manually push the pull rod 5. The pull rod 5 will push the threaded block 6 to slide. After the threaded block 6 slides a certain distance, the two sets of threaded blocks 6 will abut against each other. At this time, the third magnet 602 is energized, and the two sets of third magnets 602 will attract each other. At this time, the two sets of threaded blocks 6 will combine to form a complete fixing block. At this time, the threaded block 6 will engage and fix with the threaded hook 3, and the fixing of the threaded hook 3 can be completed.

[0048] Figure 6 As shown, when the pull rod 5 is pulled out and the threaded block 6 is separated, the third magnet 602 moves and slides into the second magnet 201. At this time, the third magnet 602 can be energized, and the third magnet 602 will attract the second magnet 201. At this time, the operator can operate the threaded hook 3.

[0049] It should be noted that when the two sets of threaded blocks 6 approach each other, the threaded grooves on the inner wall of the combined threaded block 6 match the threaded teeth on the threaded hook 3.

[0050] It should also be noted that when installing the new threaded hook 3, a certain amount of lubricating oil can be applied to the threaded block 6.

[0051] Figure 5 , Figure 6 , Figure 8 As shown, a first sliding groove 401 is provided on the mounting plate 4, and a first limiting block 4011 is slidably connected in the first sliding groove 401. The first limiting block 4011 is fixedly connected to the bottom wall of the threaded block 6.

[0052] By allowing the first limiting block 4011 to slide in the first groove 401, the stability of the threaded block 6 during movement can be improved.

[0053] Figure 5 , Figure 6 , Figure 8 As shown, a second sliding groove 402 is provided on the side wall of the mounting plate 4, and a second limiting block 601 is slidably connected in the second sliding groove 402. The second limiting block 601 is fixedly connected to the side wall of the threaded block 6.

[0054] By limiting the sliding of the second limiting block 601 in the second slide groove 402, the stability of the threaded block 6 during movement can be further improved.

[0055] The pull rod 5 has a mounting hole 501.

[0056] By using the mounting hole 501 on the pull rod 5, when it is necessary to pull out the pull rod 5, the operator can insert a pry bar into the mounting hole 501 of the pull rod 5 and then quickly pull out the pull rod 5 by using the pry bar.

[0057] The inner wall of the mounting hole 501 has anti-slip texture 5011.

[0058] By setting anti-slip texture 5011 on the inner wall of the mounting hole 501, the friction between the pry bar and the pull rod 5 can be increased, thereby ensuring that the operator can stably pull the pull rod 5 out with the pry bar.

[0059] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
