Description

Technical Field

[0001] This invention relates to the field of anchor chain shackle technology, and more specifically, to an anti-detachment structure for high-load anchor chain shackles and a device for quick disassembly and assembly of their stops. Background Technology

[0002] Anchor chain shackles are important marine rigging tools, mainly used to connect anchor chains and ballasts, ensuring that ships are securely anchored to the seabed when moored. They consist of two main parts: the body and the cross pin. In terms of shape, they are divided into straight and round types. According to their application, they can be divided into anchor chain shackles specifically for anchor chain connections and sail shackles for sail and line connections. According to the type of cross pin, they can be divided into threaded pin shackles and plain straight pin shackles. Plain straight pin shackles usually use cotter pins for fixing to ensure the stability of the connection.

[0003] In existing technology, when installing anchor chain shackles, the U-shaped opening of the shackle must first be aligned with the anchor chain link or related equipment to be connected. Then, the shackle pin is inserted and fully tightened. For threaded pins, they need to be tightened until they fit tightly against the surface of the shackle body. For unthreaded pins, it is necessary to ensure that they are inserted in place so that they fit tightly against the shackle body. Finally, a safety pin or thin steel wire is used to pass through the hole at the end of the pin and fix it in place to effectively prevent the pin from loosening during use.

[0004] In practical applications of ship berthing and anchor chain connection, the method of fixing some threaded pins to shackles is usually to first insert the threaded pin into the body of the shackle, and then tighten it with a nut to ensure the stability of the connection.

[0005] However, during long-term use, nuts are prone to rusting due to prolonged exposure to the humid marine environment. This rusting not only reduces the mechanical properties of the nuts but may also cause the connection between the nuts and threaded pins to loosen. Under external forces, such as the swaying of a ship under the action of waves or the pulling of the anchor chain, the loose nuts can easily slip out further, causing the threaded pins to fall off the shackles. This falling off not only undermines the stability of the connection between the anchor chain and the shackles but may also cause serious safety hazards.

[0006] To address this issue, a high-load anchor chain shackle anti-detachment structure and its quick-release assembly / disassembly equipment are proposed to improve existing problems. Summary of the Invention

[0007] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an anti-detachment structure for high-load anchor chain shackles and a quick disassembly and assembly device for its stops.

[0008] To achieve the above objectives, the present invention provides the following technical solution: an anti-detachment structure for a high-load anchor chain shackle, comprising an anchor chain shackle body, the anchor chain shackle body including a buckle body, a horizontal shaft, a threaded post, and a nut; the buckle body is inverted U-shaped, with buckle holes symmetrically opened on the side walls at both ends of the buckle body; the horizontal shaft has a T-shaped cross-section, and both ends of the horizontal shaft can be fitted into corresponding buckle holes; one end of the threaded post is connected to one end of the horizontal shaft, and the nut can be threaded onto the threaded post; an anti-detachment component is also provided at the end of the horizontal shaft away from the threaded post, the anti-detachment component including a fixed cylinder, an input rod disposed in the fixed cylinder, an output rod disposed at one end of the input rod, a limiting frame sleeved on the input rod, limiting rollers symmetrically disposed in the limiting frame, and springs disposed between the limiting rollers.

[0009] The invention is further configured such that: an internal thread groove is formed in one of the buckle holes, and an external thread groove is formed on the side wall of the horizontal shaft near the threaded post, the external thread groove being threaded to the internal thread groove; a spline groove is also formed at the end of the horizontal shaft away from the threaded post; the diameter of the threaded post is smaller than the diameter of the horizontal shaft.

[0010] The present invention is further configured such that: a cavity is provided inside the fixed cylinder, the input rod and the output rod are both located inside the cavity, and an insertion hole is provided at the end of the output rod near the input rod, and the end of the input rod near the output rod can be inserted into the insertion hole.

[0011] The invention is further configured such that: the end of the input rod away from the output rod passes through the side wall of the fixed cylinder and is provided with a horizontal block; an annular eye is provided on the side wall of the horizontal block; and the end of the output rod away from the input rod passes through the side wall of the fixed cylinder and is inserted into the spline groove.

[0012] The present invention is further configured such that: the side of the limiting frame is inverted L-shaped, the horizontal side wall of the limiting frame is located above the output rod, the top of the limiting frame is provided with a limiting groove, and the limiting rollers are all located in the limiting groove; the side wall of the output rod is symmetrically provided with inclined surfaces, and the limiting rollers are located on the corresponding inclined surfaces.

[0013] The present invention is further configured such that: a miniature cylinder is symmetrically arranged on the side wall of the limiting frame in the horizontal direction, and the telescopic end of the miniature cylinder penetrates the side wall of the limiting frame and extends into the limiting groove.

[0014] The present invention is further configured such that: a fixing plate is symmetrically provided on the outer wall of the fixing cylinder, the fixing plate is in the shape of an inverted L, a first fixing groove is provided on the side wall of the fixing plate, a second fixing groove is provided on one side of the first fixing groove, the first fixing groove is relatively distributed, and the second fixing groove is relatively distributed.

[0015] The quick assembly and disassembly device for the locking components uses the anti-detachment structure of the high-load anchor chain shackle as described above, including a displacement assembly, with tightening assemblies symmetrically arranged below the displacement assembly; the displacement assembly includes a support frame symmetrically arranged in the radial direction, a Y-axis electric linear guide rail arranged on the top of the support frame, an X-axis electric linear guide rail arranged between the Y-axis electric linear guide rails, a lifting cylinder arranged on one side of the X-axis electric linear guide rail, a clamping cylinder arranged at the telescopic end of the lifting cylinder, and clamping plates symmetrically arranged at the clamping end of the clamping cylinder.

[0016] The present invention is further configured such that: the tightening assembly includes a slide cylinder, a slide plate disposed at the telescopic end of the slide cylinder, a rotary cylinder disposed at one end of the slide plate, an electric gripper disposed at the rotating end of the rotary cylinder, and gripper plates symmetrically disposed at the clamping end of the electric gripper.

[0017] The present invention is further configured such that: a slide rail is symmetrically arranged in the radial direction at the bottom of the slide cylinder, an electric slider is slidably connected on the slide rail, and the top of the electric slider is connected to the bottom of the corresponding slide cylinder.

[0018] In summary, this application includes at least one of the following beneficial technical effects: (1) By rotating the input rod, the output rod and the limit frame rotate synchronously. Since there is a spring between the two limit rollers, one limit roller will squeeze the other limit roller, so that the limit frame cannot rotate and the input rod cannot rotate easily. This achieves the purpose of keeping the position unchanged after adjusting the rotation angle. At the same time, one limit roller will also limit the rotation of the output rod, so that any torque applied to the output rod is ineffective and the input rod cannot be rotated in the opposite direction through the output rod. This ensures that when any torque rotates the horizontal shaft, the horizontal shaft and the buckle cannot be loosened. This avoids the nut from being exposed to the humid marine environment for a long time and easily rusting. This rusting phenomenon will not only reduce the mechanical properties of the nut, but may also cause the connection between the nut and the threaded pin to loosen. Under the action of external force, such as the swaying of the ship under the action of waves or the pulling of the anchor chain, the loose nut is easy to slip further, which will lead to the threaded pin falling out of the shackle. This further improves the connection stability between the anchor chain and the shackle. Attached Figure Description

Detailed Implementation

[0030] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0031] Please see Figures 1-10 The present invention provides the following technical solutions: Example 1, see Figures 1-8The anti-detachment structure of the high-load anchor chain shackle includes the anchor chain shackle body 1, which includes a buckle body 11, a horizontal shaft 12, a threaded post 13, and a nut 14. The buckle body 11 is U-shaped, and buckle holes 111 are symmetrically opened on the side walls at both ends of the buckle body 11. The cross section of the horizontal shaft 12 is T-shaped, and both ends of the horizontal shaft 12 can be inserted into the corresponding buckle holes 111. One end of the threaded post 13 is connected to one end of the horizontal shaft 12, and the nut 14 can be threaded onto the threaded post 13.

[0032] The end of the horizontal shaft 12 away from the threaded post 13 is also provided with an anti-detachment component 2. The anti-detachment component 2 includes a fixed cylinder 21, an input rod 22 disposed in the fixed cylinder 21, an output rod 23 disposed at one end of the input rod 22, a limiting frame 24 sleeved on the input rod 22, limiting rollers 25 symmetrically disposed in the limiting frame 24, and springs 26 disposed between the limiting rollers 25.

[0033] When installing the anchor chain shackle body 1, one end of the horizontal shaft 12 is first passed through the two buckle holes 111 of the buckle body 11, so that the threaded post 13 extends out of the buckle hole 111. Then, the nut 14 is tightened by thread, thereby achieving the purpose of locking and fixing the buckle body 11 and the horizontal shaft 12.

[0034] It should be noted that the diameter of the threaded post 13 is smaller than the diameter of the horizontal axis 12, so there is no interference when the threaded post 13 passes through the snap hole 111.

[0035] Next, rotating the input rod 22 causes the output rod 23 and the limiting frame 24 to rotate synchronously. Since a spring 26 is installed between the two limiting rollers 25, one limiting roller 25 will compress the other, preventing the limiting frame 24 from rotating and the input rod 22 from rotating. This achieves the goal of maintaining a constant position after adjusting the rotation angle. Simultaneously, one of the limiting rollers 25 also limits the rotation of the output rod 23, rendering any torque applied to the output rod 23 ineffective and preventing it from rotating in the opposite direction. The movable input rod 22 ensures that the horizontal shaft 12 cannot be loosened when any torque force rotates it, thus preventing the nut from being easily rusted due to long-term exposure to the humid marine environment. This rusting not only reduces the mechanical properties of the nut but may also cause the connection between the nut and the threaded pin to loosen. Under external forces, such as the swaying of the ship under the action of waves or the pulling of the anchor chain, the loose nut can easily slip further, leading to the threaded pin falling out of the shackle. This further improves the connection stability between the anchor chain and the shackle.

[0036] See Figures 1-8Furthermore, an internal threaded groove 112 is provided in one of the buckle holes 111, and an external threaded groove 121 is provided on the side wall of the horizontal shaft 12 near the threaded post 13. The external threaded groove 121 can be threadedly connected to the internal threaded groove 112. A spline groove 122 is also provided at the end of the horizontal shaft 12 away from the threaded post 13. The diameter of the threaded post 13 is smaller than the diameter of the horizontal shaft 12.

[0037] When the horizontal shaft 12 passes through two buckle holes 111, the horizontal shaft 12 is rotated first, so that the external thread groove 121 on the horizontal shaft 12 is screwed and fixed with the internal thread groove 112 in one of the buckle holes 111, thereby achieving the purpose of locking and fixing the buckle body 11 and the horizontal shaft 12.

[0038] When the thread of the horizontal shaft 12 has rotated half a turn remaining, stop rotating. Then, insert and fix the output rod 23 into the spline groove 122 of the horizontal shaft 12. Next, rotate the input rod 22 by 90 degrees so that the output rod 23 and the limiting frame 24 rotate synchronously. Since a spring 26 is provided between the two limiting rollers 25, one limiting roller 25 will squeeze the other limiting roller 25, making it impossible for the limiting frame 24 to rotate and the input rod 22 to rotate easily. This achieves the purpose of keeping the position unchanged after adjusting the rotation angle. At the same time, one of the limiting rollers 25 will also limit the rotation of the output rod 23, thereby preventing any force applied to it from rotating. The torque force of the output rod 23 is ineffective, and the input rod 22 cannot be rotated in the opposite direction through the output rod 23. This ensures that when any torque force rotates the horizontal shaft 12, it cannot loosen the horizontal shaft 12 and the buckle body 11. This avoids the nut from being exposed to the humid marine environment for a long time, which would easily cause it to rust. This rusting phenomenon not only reduces the mechanical properties of the nut, but may also cause the connection between the nut and the threaded pin to loosen. Under the action of external forces, such as the swaying of the ship under the action of waves or the pulling of the anchor chain, the loose nut can easily slip out further, which may lead to the threaded pin falling out of the shackle. This further improves the connection stability between the anchor chain and the shackle.

[0039] It should be noted that the threads on the threaded column 13 and the external thread groove 121 on the horizontal shaft 12 are distributed in opposite directions, thus preventing both thread fixing methods from loosening when the horizontal shaft 12 rotates in the same direction.

[0040] Meanwhile, since the horizontal shaft 12 and the buckle body 11 are fixed by threaded tightening, which is torque force, the design of the anti-loosening component 2 can reduce the problem of the other end being fixed after one end of the horizontal shaft 12 rotates and loosens, thereby improving safety.

[0041] See Figures 1-8Furthermore, a cavity 211 is provided inside the fixed cylinder 21, and both the input rod 22 and the output rod 23 are located inside the cavity 211. A socket 231 is provided at the end of the output rod 23 near the input rod 22, and the end of the input rod 22 near the output rod 23 can be inserted into the socket 231.

[0042] The end of the input rod 22 away from the output rod 23 passes through the side wall of the fixed cylinder 21 and is provided with a horizontal block 27. A ring eye 271 is provided on the side wall of the horizontal block 27. The end of the output rod 23 away from the input rod 22 passes through the side wall of the fixed cylinder 21 and is inserted into the spline groove 122.

[0043] The rotation stops when the thread of the horizontal shaft 12 has only half a turn remaining. Then, the output rod 23 is inserted and fixed into the spline groove 122 of the horizontal shaft 12. Next, the horizontal block 27 is rotated 90 degrees, and the input rod 22 rotates synchronously. This causes the output rod 23 and the limiting frame 24 to rotate synchronously within the cavity 211. Because a spring 26 is provided between the two limiting rollers 25, one limiting roller 25 will compress the other, preventing the limiting frame 24 from rotating and the input rod 22 from rotating. This achieves the goal of maintaining a constant position after adjusting the rotation angle. Simultaneously, one of the limiting rollers 25 also limits the rotation of the output rod 23. This renders any torque applied to the output rod 23 ineffective, preventing the input rod 22 from being rotated in the opposite direction via the output rod 23. This ensures that any torque applied to the horizontal shaft 12 will not loosen the connection between the horizontal shaft 12 and the buckle 11. It also prevents the nut from rusting easily due to prolonged exposure to the humid marine environment. Rusting not only reduces the mechanical properties of the nut but can also loosen the connection between the nut and the threaded pin. Under external forces, such as the swaying of a ship in waves or the pulling of the anchor chain, the loose nut can easily slip further, leading to the threaded pin falling out of the shackle. This further improves the stability of the connection between the anchor chain and the shackle.

[0044] It should be noted that the input rod 22 is connected and fixed to the output rod 23 through the insertion hole 231; after the horizontal block 27 is rotated 90 degrees, the safety pin is passed through the ring eye 271 of the horizontal block 27 and fixed.

[0045] See Figures 1-8 Furthermore, the side of the limiting frame 24 is inverted L-shaped, the horizontal side wall of the limiting frame 24 is located above the output rod 23, the top of the limiting frame 24 has a limiting groove 241, and the limiting rollers 25 are all located in the limiting groove 241; the side wall of the output rod 23 has symmetrical inclined surfaces 232, and the limiting rollers 25 are located on the corresponding inclined surfaces 232.

[0046] Miniature cylinders 28 are symmetrically arranged on the horizontal side wall of the limiting frame 24. The telescopic end of the miniature cylinder 28 passes through the side wall of the limiting frame 24 and extends into the limiting groove 241.

[0047] During the synchronous rotation of the output rod 23 and the limiting frame 24 within the cavity 211, a spring 26 is provided between the two limiting rollers 25. Therefore, one limiting roller 25 will squeeze the other limiting roller 25 within the limiting groove 241. One limiting roller 25 will also roll on the corresponding inclined surface 232 and approach the other corresponding inclined surface 232. The other limiting roller 25 will roll along the other corresponding inclined surface 232. Since the limiting rollers 25 are all located within the limiting groove 241, the limiting groove 241 restricts the rolling range of the two limiting rollers 25.

[0048] During this process, the corresponding micro cylinder 28 is activated, squeezing the corresponding limiting roller 25, causing one limiting roller 25 to squeeze the other limiting roller 25, preventing the limiting frame 24 from rotating and the input rod 22 from rotating, thus achieving the purpose of keeping the position unchanged after adjusting the rotation angle; at the same time, one of the limiting rollers 25 also limits the rotation of the output rod 23, thus making any torque applied to the output rod 23 ineffective, and unable to rotate the input rod 22 in the opposite direction through the output rod 23, thereby ensuring that when any torque is applied to rotate the horizontal shaft 12, it will not cause the horizontal shaft 12 to loosen from the buckle body 11, avoiding the nut from being exposed to the humid marine environment for a long time, which is prone to rust. This rusting phenomenon will not only reduce the mechanical properties of the nut, but may also cause the connection between the nut and the threaded pin to loosen. Under the action of external forces, such as the swaying of the ship under the action of waves or the pulling of the anchor chain, the loose nut can easily slip out further, leading to the threaded pin falling out of the shackle, thus further improving the connection stability between the anchor chain and the shackle.

[0049] See Figures 1-8 Furthermore, a fixing plate 29 is symmetrically provided on the outer wall of the fixing cylinder 21. The fixing plate 29 is inverted L-shaped. A first fixing groove 291 is provided on the side wall of the fixing plate 29. A second fixing groove 292 is provided on one side of the first fixing groove 291. The first fixing groove 291 and the second fixing groove 292 are relatively distributed.

[0050] The buckle body 11 is clamped by the first fixing groove 291 on both sides, the outer wall of the fixing cylinder 21 is clamped by the second fixing groove 292 on both sides, and finally it is fixed by bolts.

[0051] Example 2, see Figures 9-10Furthermore, the quick disassembly and assembly equipment for the gear uses the aforementioned high-load anchor chain shackle anti-detachment structure, including a displacement component 3, with a tightening component 4 symmetrically arranged below the displacement component 3; the displacement component 3 includes a support frame 31 symmetrically arranged in the radial N direction, a Y-axis electric linear guide rail 32 arranged on the top of the support frame 31, an X-axis electric linear guide rail 33 arranged between the Y-axis electric linear guide rails 32, a lifting cylinder 34 arranged on one side of the X-axis electric linear guide rail 33, a clamping cylinder 35 arranged at the telescopic end of the lifting cylinder 34, and a clamping plate 36 symmetrically arranged at the clamping end of the clamping cylinder 35.

[0052] Specifically, starting the Y-axis electric linear guide 32 can drive the buckle body 11 to move horizontally in the radial N direction; starting the X-axis electric linear guide 33 can drive the buckle body 11 to move horizontally in the axial M direction; starting the lifting cylinder 34 can drive the buckle body 11 to move vertically; and finally, starting the clamping cylinder 35 can cause the two clamping plates 36 to clamp the buckle body 11, thereby enabling precise displacement of the anchor chain shackle body 1.

[0053] See Figures 9-10 Furthermore, the tightening assembly 4 includes a slide cylinder 41, a slide plate 42 disposed at the telescopic end of the slide cylinder 41, a rotary cylinder 43 disposed at one end of the slide plate 42, an electric gripper 44 disposed at the rotating end of the rotary cylinder 43, and gripper plates 45 symmetrically disposed at the clamping end of the electric gripper 44.

[0054] The bottom of the slide cylinder 41 is also symmetrically provided with slide rails 46 in the radial N direction. An electric slider 47 is slidably connected on the slide rail 46. The top of the electric slider 47 is connected to the bottom of the corresponding slide cylinder 41.

[0055] The electric slider 47 is activated, which drives the slide cylinder 41 to make a horizontal displacement in the radial N direction on the slide rail 46. Then the slide cylinder 41 is activated, which drives the claw plate 45 to approach the buckle body 11 through the slide plate 42. Then the electric gripper 44 is activated, so that the two claw plates 45 can clamp the nut 14 or the cross block 27. Finally, the rotation of the rotary cylinder 43 can realize the locking and fixing of the nut 14 and the threaded post 13, as well as the 90-degree rotation of the cross block 27.

[0056] Obviously, the embodiments described above are merely some, not all, embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
