Description

Technical Field

[0001] The present invention relates to the technical field of anchor chain shackles, and specifically to a ship anchor chain connection shackle structure. Background Technique

[0002] Anchor chain shackles are mainly used to connect the anchor chain and the ship anchor. The shackle usually consists of a U-shaped body and a transverse pin, which is convenient for replacing the ship anchor after disassembly. The anchor chain shackle needs to meet the stiffness requirements to ensure its service life. Currently, the ship anchor chain shackles are usually of a fixed structure, and there is a risk that the ship anchor gets stuck in the reef area. Once the ship anchor gets stuck, it is usually necessary to disassemble the Kent shackle of the anchor chain on the ship to abandon the anchor, resulting in a large section of the anchor chain being discarded, increasing the cost of losing the anchor. It is not convenient to disassemble the underwater anchor chain shackle when the ship anchor gets stuck. At the same time, the manual operation of disassembling the Kent shackle is relatively dangerous, and it is not convenient to automatically monitor the connection stability of the shackle. At the same time, the swivel on the shackle can adapt to the torsion when the ship anchor enters the water, reducing the risk of the anchor chain entanglement. However, after the ship anchor is anchored, the ship anchor no longer twists. At this time, the main torsional force lies in the underwater turbulence, etc. The traditional shackle conversion is not convenient for automatic locking and anti-torsion, increasing wear and not being convenient for using the ship anchor for positioning to prevent the anchor chain from entanglement.

[0003] Therefore, we propose a ship anchor chain connection shackle structure. Summary of the Invention

[0018] The use of an anchoring locking member can facilitate the improvement of the stability of the anchor chain after the structure is anchored to the seabed. By using an anchor with stable anchoring, at this time, the swivel shaft that locks the anchor chain and the anchor are made unable to rotate, which can prevent the anchor from twisting and entangling.

[0031] Embodiment 1: Please refer to Figures 1 to 10 as shown:

[0032] The present invention provides a technical solution: a shackle structure for connecting a ship's anchor chain, including a shackle mounting member 1, a swing connecting member 2 is mounted on the shackle mounting member 1, and the swing connecting member 2 is used to connect the ship's anchor; an in-place prompting member 3 is fixedly mounted on the side of the shackle mounting member 1; the in-place prompting member 3 is used for safety detection; two limit locking members 4 are slidably inserted on the shackle mounting member 1, and the two limit locking members 4 are used for anti-disconnection and limit; a seabed detection member 5 is fixedly mounted at the bottom of the shackle mounting member 1; the seabed detection member 5 is used to control the limit locking member 4; an anchoring and locking member 6 is mounted on the shackle mounting member 1; a recovery anti-friction member 7 is mounted on the shackle mounting member 1, and the recovery anti-friction member 7 is used to position the swing connecting member 2; the shackle mounting member 1 includes: a buckle body 101 and a one-way bearing 102, two one-way bearings 102 are respectively fixedly sleeved at both ends of the buckle body 101, and threads are respectively provided on the inner rings of the four one-way bearings 102.

[0033] Among them, the shackle installation part 1 further includes: a locking ring 103 and a locking collar 104. The locking rings 103 are respectively fixedly installed on the sides of the one-way bearings 102 on both sides; and a circle of positioning grooves are respectively provided on the two locking rings 103; the locking collar 104 is fixedly installed on the top of the buckle body 101, and a circle of positioning grooves are provided on the locking collar 104; the swing connecting part 2 includes: a threaded cross pin 201, a driving sleeve 202, a drag-reducing ball 2021, and a V-shaped plate 203. The threaded cross pin 201 is threadedly connected to the inner rings of the four one-way bearings 102; a driving sleeve 202 is sleeved on the threaded cross pin 201; four sliding grooves are provided on the threaded cross pin 201; four protrusions are provided on the driving sleeve 202, and the four protrusions on the driving sleeve 202 are located in the four grooves on the threaded cross pin 201; four drag-reducing balls 2021 are embedded in the inner side of the driving sleeve 202, and the four drag-reducing balls 2021 respectively roll and fit in the four sliding grooves provided on the threaded cross pin 201; two V-shaped plates 203 are fixedly installed on the driving sleeve 202, and the V-shaped plates 203 are used for welding on the side of the anchor; the in-place reminder 3 includes: a spring steel sheet 301, a reminder lamp 302, and an in-place switch 303. The spring steel sheet 301 is an L-shaped spring sheet structure; the spring steel sheet 301 is fixedly installed on the side of the buckle body 101; the reminder lamp 302 is fixedly installed on the spring steel sheet 301; the in-place switch 303 is fixedly installed on the spring steel sheet 301; the in-place switch 303 is electrically connected to the reminder lamp 302;The side of the threaded cross pin 201 is extruded and fitted in place with the switch 303. The swinging connecting piece 2 can be used to maintain a stable connection to the anchor. At the same time, when the anchor gets stuck during anchor retrieval, the swinging connecting piece 2 can facilitate the complete recovery of the anchor chain of this structure. Only the anchor can be discarded, which can reduce cost losses. At the same time, it is convenient to directly replace the anchor later, reducing the maintenance cycle. This structure can utilize the one-way bearing 102 to automatically disassemble the threaded cross pin 201 by controlling the winch to take in and release the anchor chain multiple times, without the need for manual underwater operation, which is safer. Especially for reef areas, it can ensure the flexibility of use. At the same time, this structure uses the in-place reminder piece 3 to be used for real-time testing of the stable installation in place of the threaded cross pin 201, avoiding the situation where the threaded cross pin 201 becomes loose and has a large displacement, affecting the connection stability of the anchor and not being discovered, which can facilitate prompting the staff to carry out maintenance work in a timely manner and reduce the risk of anchor detachment. After the anchor is lowered into the water and anchored, because the ship continuously pulls the anchor, at this time, the buckle body 101 is in a straight line relative to the anchor arm. Subsequently, when retrieving the anchor, it is necessary to lift the anchor chain upward. At this time, the anchor chain will drive the buckle body 101 to rotate upward on the anchor arm to lift the anchor. At this time, the buckle body 101 and the anchor arm are no longer in the same straight line and an angular rotation occurs. Normally, the anchor can be lifted before. If the anchor gets stuck and cannot be lifted at this time, the above-mentioned anchor chain take-in and release actions can be repeated. At this time, with the traction of the anchor chain, a rotation will occur between the buckle body 101 and the threaded cross pin 201. By controlling the take-in and release of the anchor chain back and forth, as the buckle body 101 and the threaded cross pin 201 rotate back and forth, because the drive sleeve 202 on the outside of the threaded cross pin 201 is connected to the anchor through the V-shaped plate 203, at this time, under the limit of the drag-reducing ball 2021, the stuck anchor will not displace with the buckle body 101. At this time, with the back-and-forth rotation of the buckle body 101 and the one-way limit of the one-way bearing 102, in the other direction, because there is also friction between the threaded cross pin 201 and the one-way bearing 102, the one-way bearing 102 will be in an idling state. When the buckle body 101 rotates, the threaded cross pin 201 will move inside the one-way bearing 102 to the opposite side of the in-place switch 303 to achieve detachment.;

[0034] Among them, the limit locking member 4 includes a locking insertion cylinder 401, an anti-jamming spring 402, insertion teeth 403, and a locking electromagnet 404. The outer side of the locking insertion cylinder 401 is a dodecagonal structure. The locking insertion cylinder 401 is slidably inserted into the side surface of the buckle body 101. An anti-jamming spring 402 is sleeved on the locking insertion cylinder 401, and the anti-jamming spring 402 is located between the locking insertion cylinder 401 and the buckle body 101. A circle of insertion teeth 403 is fixedly installed inside the locking insertion cylinder 401, and the circle of insertion teeth 403 is respectively used for being inserted into a circle of grooves on the locking ring 103. A locking electromagnet 404 is fixedly installed inside the buckle body 101, and the locking electromagnet 404 is aligned with the locking insertion cylinder 401. The locking electromagnet 404 is used for magnetically attracting the locking insertion cylinder 401. The locking insertion cylinder 401 is located outside the threaded cross pin 201. The seabed detection member 5 includes a detection connection cylinder 501, a sliding shaft 502, and a bottom contact switch 503. The detection connection cylinder 501 is fixedly installed at the bottom of the buckle body 101. The sliding shaft 502 is slidably installed inside the detection connection cylinder 501. A spring is sleeved on the sliding shaft 502, and the spring on the sliding shaft 502 is connected between the detection connection cylinder 501 and the sliding shaft 502. The top of the sliding shaft 502 is fixedly installed with a bottom contact switch 503, and the end of the bottom contact switch 503 is pressed against and fits the inner side of the detection connection cylinder 501. The bottom contact switch 503 is electrically connected to the locking electromagnet 404. The seabed detection member 5 further includes a counterweight ball 504. The bottom of the sliding shaft 502 is connected to the counterweight ball 504 through a steel wire. The gravity of the counterweight ball 504 is greater than the elastic force of the spring on the sliding shaft 502. By using the seabed detection member 5 in cooperation with the limit locking member 4, it can be used to prevent the structure from being affected by factors such as ocean turbulence during the process of the ship anchor being lowered into the water, causing the ship anchor to swing, and when there is a swinging rotation between the buckle body 101 and the ship anchor arm, driving the threaded cross pin 201 to displace, resulting in the problem of detachment after long-term use. It can ensure that the one-way drive can only be carried out normally after the ship anchor touches the bottom, and the problem of accidental loss of the anchor can be prevented. At the same time, the structure can utilize the characteristic that the limit locking member 4 can lock the one-way bearing 102. When the ship anchor is affected by factors such as ocean turbulence and causes the ship anchor to swing, the threaded cross pin 201 can only rotate back and forth and cannot rotate unidirectionally, preventing detachment. When the counterweight ball 504 does not touch the bottom, at this time, under the traction of the counterweight ball 504, the bottom contact switch 503 is not squeezed by the detection connection cylinder 501. At this time, the locking electromagnet 404 magnetically attracts the locking insertion cylinder 401, driving the insertion teeth 403 to insert into the locking ring 103, locking the limit one-way bearing 102. At this time, the threaded cross pin 201 cannot achieve unidirectional rotational displacement.

[0035] Among them, the anchoring and locking member 6 includes: a swivel shaft 601 and a release electromagnet 602. This structure can be powered by a battery. A link is provided at the top of the swivel shaft 601; the swivel shaft 601 is rotatably installed on the buckle body 101; the middle section of the swivel shaft 601 is a hexagonal column structure; a release electromagnet 602 is fixedly installed on the swivel shaft 601; the bottom contact switch 503 is electrically connected to the release electromagnet 602; the anchoring and locking member 6 further includes: a downward pressure locking cylinder 603, the inner side of the downward pressure locking cylinder 603 is a hexagonal structure; the downward pressure locking cylinder 603 is slidably installed on the swivel shaft 601; the bottom of the downward pressure locking cylinder 603 is inserted into a circle of positioning grooves provided on the locking ring 104; a spring is connected between the downward pressure locking cylinder 603 and the release electromagnet 602, and the spring between the downward pressure locking cylinder 603 and the release electromagnet 602 is sleeved on the swivel shaft 601; the release electromagnet 602 is used to magnetically attract the downward pressure locking cylinder 603; the use of the anchoring and locking member 6 can facilitate improving the stability of the anchor chain after the structure is anchored to the seabed. With an anchor having stable anchoring, at this time, the swivel shaft 601 locking the anchor chain and the anchor cannot rotate, which can prevent the anchor from twisting and entangling. At the same time, when anchoring, when the anchor has not touched the bottom, the rotation between the swivel shaft 601 and the anchor can be maintained, which can prevent the anchor from driving the anchor chain to twist together when it rotates due to interference by factors such as turbulent flow. It can cooperate with the seabed detection member 5 for detection and control. After the anchor is lifted or anchored, when the anchor touches the bottom, that is, after the counterweight ball 504 touches the bottom, at this time, the anchor is stably anchored, and the downward pressure locking cylinder 603 can be inserted into the locking ring 104 to position the anchor chain, and the stable anchoring of the anchor is utilized to prevent the anchor chain from twisting.

[0036] Embodiment 2, on the basis of Embodiment 1, the recovery and anti-friction member 7 includes: a downward pressure ring 701, a plugging rod 7011, an anti-mis-touch pull spring 702, and a support stop rod 703. There are two downward pressure rings 701, and the two downward pressure rings 701 are respectively slidably sleeved on the buckle body 101; a plugging rod 7011 is fixedly installed between the two downward pressure rings 701, and the plugging rod 7011 is located inside the two V-shaped plates 203; two anti-mis-touch pull springs 702 are sleeved on the buckle body 101, and the two anti-mis-touch pull springs 702 are respectively connected between the buckle body 101 and the downward pressure ring 701; support stop rods 703 are respectively fixedly installed on the two downward pressure rings 701, and the two support stop rods 703 are used to stop at the anchor chain hole. The use of the recovery and anti-friction member 7 can reduce the wear between the threaded cross pin 201 and the control buckle body 101 during the daily suspension of the anchor, improve the service life of this structure, and at the same time can play a role in stabilizing the anchor, and the staff can more directly observe the state of the anchor in place.

[0037] The working principle of this embodiment is as follows: first, the driving sleeve 202 passes through the anchor, and the V-shaped plate is welded to the side of the anchor. After the anchor is launched into the water and anchored, because the ship continues to pull the anchor, the buckle body 101 is in a straight line relative to the anchor arm. When raising the anchor later, it is necessary to pull the anchor chain upward. At this time, the anchor chain will drive the buckle body 101 to rotate upward on the anchor arm to lift the anchor. At this time, the buckle body 101 and the anchor arm are no longer in the same straight line, and an angle rotation occurs. Under normal circumstances, the anchor can be lifted before. If the anchor is stuck and cannot be lifted at this time, the above-mentioned anchor chain retracting and releasing action can be repeated. At this time, with the traction of the anchor chain, the buckle body 101 and the threaded cross pin 201 will rotate. The anchor chain is retracted and released back and forth. As the buckle body 101 and the threaded cross pin 201 rotate back and forth, because the driving sleeve 202 on the outside of the threaded cross pin 201 is connected to the anchor through the V-shaped plate 203, the stuck anchor will not follow the displacement of the buckle body 101 under the limit of the drag reduction ball 2021. At this time, as the buckle body 101 rotates back and forth, with the one-way limit of the one-way bearing 102, the one-way bearing 102 will be in an idling state because there is friction between the threaded cross pin 201 and the one-way bearing 102 in the other direction. When the buckle body 101 rotates, the threaded cross pin 201 will move inside the one-way bearing 102 to the opposite side of the in-place switch 303. At this time, as the buckle body 101 drives the one-way bearing 102 to rotate unidirectionally The threaded cross pin 201 is rotated, and the threaded cross pin 201 continues to move to one side to realize the disassembly and disengagement of the driving sleeve 202. At this time, the anchor can be disassembled separately to reduce the loss. The longer the length of the threaded cross pin 201 is, the more times the buckle body 101 needs to be controlled to rotate back and forth to prevent the anchor from falling off due to daily use. At the same time, once the threaded cross pin 201 no longer presses the in-place switch 303, the in-place switch 303 can control the prompt light 302 to light up as a prompt, and the anchor can be recovered to the splint and then an electric wrench or other instrument can be used manually to drive the threaded cross pin 201 to reset, thereby ensuring continuous use. When the counterweight ball 504 does not touch the bottom, the bottom switch 503 is not squeezed by the detection connecting tube 501 under the traction of the counterweight ball 504. At this time, the locking electromagnet 404 magnetically locks the plug-in cylinder 401, drives the plug-in tooth 403 to plug the locking ring 103, and locks the limited one-way bearing 102. At this time, the threaded cross pin 201 cannot achieve unidirectional rotation displacement. On the contrary, if the counterweight ball 504 touches the bottom, the counterweight ball 504 no longer pulls the sliding shaft 502. Under the pressure of the spring on the sliding shaft 502, the bottom switch 503 moves up and is squeezed by the detection connecting cylinder 501, which can control the locking electromagnet 404 to cut off the power, cooperate with the anti-stuck spring 402 to squeeze, drive the plug-in tooth 403 and the locking ring 103 to separate. If the anchor is stuck, the anchor machine can be used to retract and release the anchor chain, drive the buckle body 101 to swing back and forth, and drive the threaded cross pin 201 to separate in one direction;When the anchor has not touched the bottom, the touch bottom switch 503 can be used to control the release of the electromagnet 602 to energize and magnetically attract the lower pressing locking cylinder 603 to move upward, thereby releasing the plug-in limit locking ring 104. At this time, the swivel shaft 601 can rotate normally to adapt to the anchor. When the anchor touches the bottom, that is, when the counterweight ball 504 touches the bottom, the anchor is stably anchored at this time. The electromagnet 602 is de-energized. Under the extrusion of the spring on the lower pressing locking cylinder 603, the lower pressing locking cylinder 603 can be inserted into the locking ring 104 to position the anchor chain, and the stable anchoring of the anchor is used to prevent the anchor chain from twisting. As the anchor chain is recovered, when the support stop rod 703 moves to the outside of the anchor chain hole, the anchor chain hole can stop the support stop rod 703 at this time. At this time, the anchor chain is still being recovered, and the lower pressing ring 701 will drive the plug-in rod 7011 to move downward. The anti-mis-touch pull spring 702 is stretched, and the plug-in rod 7011 will be inserted into the V-shaped plate 203 for positioning.
