Description

Technical Field

[0001] This utility model belongs to the field of three-grip anchor technology, specifically relating to a heavy-duty three-grip anchor hook. Background Technology

[0002] In the field of marine salvage operations, the performance of salvage tools is directly related to the efficiency and success rate of salvage work. The three-claw anchor hook, as a commonly used salvage equipment, is widely used in scenarios such as salvaging shipwreck anchor chains, cables, and other underwater heavy objects.

[0003] However, the traditional three-claw anchor hook has obvious defects in its structure: the claws of the existing three-claw anchor hook have a small deployment angle, which limits its gripping range and gripping ability. The small deployment angle makes it difficult for the claws to accurately lasso the anchor chain or cable when approaching the target object, especially in sea areas with strong currents and low visibility, this limitation is more obvious. From the perspective of the bottom structure of the anchor, the bottom of the traditional three-claw anchor hook is usually hollow. Although this design reduces the overall weight of the anchor to a certain extent, it also seriously weakens the anchor's load-bearing capacity. When salvaging heavy objects or encountering complex seabed topography, the hollow bottom of the anchor is prone to deformation or even damage due to excessive force, resulting in salvage failure. Therefore, this utility model proposes a heavy-duty three-claw anchor hook. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example

[0025] Please see Figures 1 to 4 This is an embodiment of the present utility model, which provides the following technical solution: a heavy-duty three-grip anchor hook, comprising...

[0026] Solid end 1: The solid structure design greatly enhances the anchor's load-bearing capacity, enabling it to withstand heavier objects and the enormous tensile forces brought about by complex seabed topography. It is not prone to deformation or damage, ensuring the stability and reliability of salvage operations.

[0027] Three large-spreading anchor hooks 3 are evenly distributed on the circumference of the solid end 1. Compared with traditional anchor hooks, the large-spreading anchor hooks 3 have reduced curvature, making the spread of the large-spreading anchor hooks 3 larger than that of traditional anchor hooks, greatly increasing the grabbing area, optimizing the contact method between the large-spreading anchor hooks 3 and the target object, making it easier and more stable to hook the ship's anchor chain or cable;

[0028] A solid reinforcing seat 2 is set on the surface of the solid end 1 and located between two adjacent large-expansion anchor hooks 3, further reinforcing and strengthening the area between the two adjacent large-expansion anchor hooks 3;

[0029] The hollow end 4 is detachably installed at the rear end of the solid end 1. The detachable design facilitates the subsequent disassembly and maintenance between the solid end 1 and the hollow end 4.

[0030] In this embodiment, preferably, an inclined extension section 31 is provided between the rear end of the large-expansion anchor hook 3 and the solid end 1 to further reinforce and support the rear end of the large-expansion anchor hook 3.

[0031] In this embodiment, preferably, the rear end of the solid end 1 is provided with an integrated plug block 11, and the hollow end 4 is provided with a plug slot 43 for the plug block 11 to be inserted into, and the plug block 11 is inserted into the plug slot 43.

[0032] In this embodiment, preferably, a disassembly and assembly structure 5 is provided between the plug-in block 11 and the hollow end 4 to stably fix the hollow end 4 and the solid end 1 together.

[0033] In this embodiment, preferably, the disassembly and assembly structure 5 includes a base plate 51 and two threaded base rods 52 welded to the side of the base plate 51. The threaded base rods 52 are inserted from one side of the hollow end 4 and pass through the plug-in block 11 to the other side of the hollow end 4. The ends of the threaded base rods 52 are fitted with locking washers 54 and locking nuts 53, so that the plug-in block 11 can be stably fixed by the disassembly and assembly structure 5 after being inserted into the plug-in groove 43.

[0034] In this embodiment, preferably, two bolt holes 44 are provided on both sides of the hollow end 4 for the threaded base rod 52 to pass through, and two bolt holes 111 are provided on the surface of the plug block 11 for the threaded base rod 52 to pass through.

[0035] In this embodiment, preferably, the substrate 51 has an arc-shaped plate contact surface 511 that fits the surface of the hollow end 4 on the side facing the hollow end 4, and the locking washer 54 has an arc-shaped washer contact surface 541 that fits the surface of the hollow end 4 on the side facing the hollow end 4, which can increase the fit with the hollow end 4 and ensure the overall stability after the daily locking nut 53 is locked.

[0036] In this embodiment, preferably, the rear end of the hollow end 4 is provided with an integrated connecting seat 41, and a cable loop 42 that can be connected to a cable is rotatably mounted on the connecting seat 41 via a rotating shaft.

[0037] In summary, when it is necessary to separate the solid end 1 and the hollow end 4 for maintenance or replacement, simply unscrew the locking nut 53 and remove the locking washer 54. Then, move the base plate 51 to the side so that the threaded base rod 52 is pulled out from between the hollow end 4 and the plug block 11, thus detaching the connection between the solid end 1 and the hollow end 4. Then, pull the plug block 11 out of the plug groove 43 to quickly complete the separation between the solid end 1 and the hollow end 4. When reassembling the solid end 1 and the hollow end 4, simply insert the plug block 11 into the plug groove 43, then attach the base plate 51 to one side of the hollow end 4 so that the threaded base rod 52 passes through the bolt hole 1 44 and the bolt hole 2 111 until the end of the threaded base rod 52 passes through to the other side of the hollow end 4. Then, put the locking washer 54 and the locking nut 53 on the end of the threaded base rod 52, and finally lock the locking nut 53 to fix it.

[0038] Although embodiments of the present invention have been shown and described (see the detailed description above), it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
