Description

Technical Field

[0001] This utility model relates to the field of shipbuilding technology, and more specifically, to a highly reliable chain abandoner. Background Technology

[0002] A chain release device is an essential specialized device for the end of an anchor chain on a ship, allowing the chain to be quickly detached from the hull in an emergency. It is typically located in an easily accessible location on the ship or on the bulkhead of the anchor chain compartment, and is connected to the chain release device via a chain link at the end of the anchor chain. The chain release device should guarantee rapid and reliable detachment of the anchor chain in an emergency. Commonly used chain release devices are primarily helical release devices, where the rotation of a screw causes a locking catch to rotate around a pin, locking the anchor chain or releasing the hook. However, most existing chain release devices require manual rotation of the screw to perform the chain release operation. In an emergency, it is difficult to open the release device promptly, resulting in low efficiency, low reliability, and low automation in emergency chain release operations. Utility Model Content

The term " / and" in this article describes another type of relationship between related objects, indicating that two relationships can exist. For example, A / and B can mean: A exists alone, and A and B exist alone. In addition, the character " / " in this article generally indicates that the related objects before and after it are in an "or" relationship.

[0033] according to Figures 1-9As shown, a high-reliability chain abandoner includes an anchor chain locking component and an automatic anchor chain abandoning component. The anchor chain locking component is installed on the ship, and the automatic anchor chain abandoning component is installed on the anchor chain locking component. The anchor chain locking component includes an anchor chain mounting component and a locking anchor chain component. The anchor chain mounting component is installed on the deck or bulkhead of the ship as needed, and the locking anchor chain component is installed on the anchor chain mounting component to lock the end of the anchor chain 1.

[0034] The anchor chain mounting component includes a mounting base 2 and a mounting cover 3. The mounting base 2 is disposed on the vessel for mounting the locking anchor chain component, and the mounting cover 3 is hinged to the mounting base 2 to provide protection.

[0035] The locking anchor chain component includes a locking anchor chain drive component, a locking positioning component, and a locking force adjusting component, all of which are mounted on the anchor chain mounting component. The locking anchor chain drive component includes an anchor chain pretensioner and an anchor chain lock head 4. The anchor chain pretensioner is mounted on the mounting base 2, and the anchor chain lock head 4 is mounted on the anchor chain pretensioner.

[0036] The anchor chain pretensioning component includes a pretensioning support tube 5, a first transmission slider 6, a first spring 7, a second transmission slider 8, and a first gear tooth 9. The sidewall of the pretensioning support tube 5 is fixedly disposed within a first mounting groove on the mounting base 2. The first mounting groove is arc-shaped and is used to increase the firmness of the pretensioning support tube 5 on the mounting base 2. The first transmission slider 6 is cylindrical, and one end of the first transmission slider 6 is axially slidably embedded in one end of the pretensioning support tube 5. The first spring 7 is embedded in the pretensioning support tube 5, and one end of the first spring 7 is connected to one end face of the first transmission slider 6. The second transmission slider 8 is cylindrical, and one end of the second transmission slider 8 is axially slidably embedded in the other end of the pretensioning support tube 5, and one end of the second transmission slider 8 is connected to the other end of the first spring 7. The first gear tooth 9 has a right-angled cross-section. The first gear tooth 9 has a right-angled side fixedly mounted on the side wall of the second transmission slider 8. The first gear tooth 9 passes through the pre-tightening groove on the side wall of the other end of the pre-tightening support tube 5. The pre-tightening groove allows the inner and outer walls of the other end of the pre-tightening support tube 5 to be connected. The pre-tightening groove is connected to the other end face of the pre-tightening support tube 5.

[0037] The anchor chain lock head 4 is generally in the shape of a thick plate. One end of the anchor chain lock head 4 is provided with a bevel, and the other end of the anchor chain lock head 4 is fixedly connected to the other end face of the first transmission slider 6. The longitudinal line of the anchor chain lock head 4 is parallel to the axis of the first transmission slider 6. This allows one end of the anchor chain lock head 4 to slide into the hole of the anchor chain 1 as the first transmission slider 6 slides to the right axially, thereby locking the anchor chain 1.

[0038] The locking and positioning component includes a telescopic locking component and a lock head locking component. The telescopic locking component is disposed on the mounting base 2, and the lock head locking component is disposed on the telescopic locking component. The telescopic locking component includes a locking support base 10, a locking slider 11, a second spring 12, a second gear tooth 13, and a sliding unlocking base 14. The locking support base 10 is rectangular in shape, and its sidewall is fixedly disposed on the mounting base 2. The locking slider 11 is rectangular in shape and is laterally slidably embedded in the groove of the locking support base 10. The second spring 12 is disposed in the groove of the locking support base 10, and its two ends are respectively connected to the bottom of the groove of the locking support base 10 and one side of the locking slider 11. The second gear tooth 13 has the same structure as the first gear tooth 9. A right-angled surface of the second gear tooth 13 is fixedly disposed on the other side of the locking slider 11, so that the other right-angled surface of the second gear tooth 13 can pass through the pre-tightening groove and mesh with the other right-angled surface of the first gear tooth 9, thereby axially locking the second transmission slider 8. Furthermore, the four second gear teeth 13 are evenly distributed longitudinally on the locking slider 11, so that when the first gear tooth 9 meshes with the four second gear teeth 13 one by one, different axial locking forces are generated, thereby adjusting the automatic chain-discarding resistance of the chain discarder. The sliding unlocking seat 14 is in the shape of a rectangular groove, and the groove of the sliding unlocking seat 14 passes through the unlocking through hole on the bottom surface of the locking support seat 10 and is fixedly connected to one side surface of the locking slider 11.

[0039] The lock cylinder locking component includes a lock cylinder support tube 15, a bolt 16, a third spring 17, and an actuating rod 18. One end of the lock cylinder support tube 15 is disposed through one end face of the locking support base 10. The bolt 16 is cylindrical and axially slides within one end of the lock cylinder support tube 15. The third spring 17 is disposed within the lock cylinder support tube 15, and its two ends are respectively connected to the bolt 16 and the other end face of the lock cylinder support tube 15. One end of the actuating rod 18 slides axially through the other end face of the lock cylinder support tube 15 and the third spring 17, and is fixedly connected to one end face of the bolt 16. This pulls the bolt 16 into the lock cylinder support tube 15, thereby pulling the other end of the bolt 16 out from the locking hole 19 on one end face of the locking slider 11, causing the second gear tooth 13 to mesh with the first gear tooth 9. When the locking slider 11 is pulled upward to a predetermined height, the other end of the locking tongue 16 will automatically insert into the locking hole 19 to disengage the second gear tooth 13 from the first gear tooth 9 for an extended period of time, facilitating automatic chain abandonment.

[0040] The locking force adjusting component includes an adjusting drive shaft 20, an adjusting wheel 21, and a handwheel 22. One end of the adjusting drive shaft 20 passes through the mounting plate 3 and is rotatably mounted on the mounting base 2. The adjusting wheel 21 is fixedly mounted on the adjusting drive shaft 20 through an adjusting through hole, and the center of the adjusting through hole does not coincide with the center of the adjusting wheel 21, so that the adjusting wheel 21 is eccentrically mounted on the adjusting drive shaft 20 and slidably fits against the other end face of the second transmission slider 8. The handwheel 22 is fixedly mounted on the other end of the adjusting drive shaft 20.

[0041] The method of using the anchor chain locking component is as follows: 1) Insert one end of the anchor chain lock head 4 into the hole of the anchor chain 1, so that the anchor chain 1 is locked on the mounting base 2; 2) Rotate the handwheel 22, and through the eccentric rotation of the adjusting wheel 21, the second transmission slider 8 is pressed to the right. The second transmission slider 8, moving to the right, presses the first transmission slider 6 to the right through the first spring 7. The first transmission slider 6 applies a locking force to the anchor chain lock head 4, thereby increasing the automatic chain abandonment resistance (when the anchor chain 1 is violently pulled by an external force and is passively abandoned, the anchor chain 1 will press the inclined surface, causing the anchor chain lock head 4 to drive the first transmission slider 6 to the right). 3) The sliding block 6 slides to the left, thereby squeezing the anchor chain lock head 4 out of the hole of the anchor chain 1 to the left, completing the automatic chain abandonment; 4) The second transmission slider 8, which is squeezed to the right by the adjusting wheel 21, makes the first wheel tooth 9 mesh with the second wheel tooth 13 to lock the second transmission slider axially; 5) When automatic chain abandonment is required, the sliding unlocking seat 14 is pulled upward by the anchor chain automatic chain abandonment component, thereby driving the locking slider 11 to move upward, thereby driving the second wheel tooth 13 to disengage from the first wheel tooth 9, allowing the second transmission slider 8 to slide freely; 6) The anchor chain automatic chain abandonment component is activated to perform active chain abandonment operation on the anchor chain 1.

[0042] The automatic chain abandonment mechanism includes an active chain abandonment power component and an active chain abandonment transmission component, both of which are mounted on the anchor chain mounting component. The active chain abandonment power component includes a motor 23, a first gear 24, and an unlocking wheel 25. The motor 23 is fixedly mounted on the mounting base 2. Furthermore, the motor 23 is a dual-axis motor. The first gear 24 is fixedly mounted on one shaft of the motor 23 for transmitting power to the active chain abandonment transmission component. The unlocking wheel 25 has an unlocking through hole. The axis of the unlocking through hole is not coincident with and is parallel to the axis of the unlocking wheel 25. The unlocking wheel 25 is fixedly mounted on another shaft of the motor 23 through the unlocking through hole, and the unlocking wheel 25 moves eccentrically on the motor 23. Simultaneously, the outer wall of the unlocking wheel 25 slides against the inner wall of the bottom surface of the groove of the sliding unlocking seat 14. When the unlocking wheel 25 is driven by the motor 23 to rotate eccentrically, it will cause the sliding unlocking groove to move upward, thereby causing the second wheel tooth 13 to move upward and disengage from the first wheel tooth 9, and causing the locking tongue 16 to insert into the locking hole 19. It should be noted that the motor 23 can be started by a remote control switch in the cab to complete the automatic chain abandonment operation.

[0043] The active chain abandonment transmission component includes a chain abandonment pusher and a chain abandonment pusher transmission component, both of which are mounted on the mounting base 2. The chain abandonment pusher includes a chain abandonment pusher seat 26, a chain abandonment pusher shaft 27, and a limiting plate 28. The chain abandonment pusher seat 26 is tubular and fixedly mounted on the mounting base 2. One end of the chain abandonment pusher shaft 27 slides axially through one end face of the chain abandonment pusher seat 26 and extends into the chain abandonment pusher seat 26. The other end of the chain abandonment pusher shaft 27 corresponds to one end face of the anchor chain lock head 4. The limiting plate 28 is fixedly fitted onto one end of the chain abandonment pusher shaft 27 to control the outward extension length of the other end of the chain abandonment pusher shaft 27, thereby preventing the other end of the chain abandonment pusher shaft 27 from vibrating and pushing the anchor chain lock head 4, thus preventing it from inserting into the hole of the anchor chain 1 and affecting chain abandonment.

[0044] The chain-breaking jacking transmission component includes a reciprocating jacking component and a continuous hammering component. The reciprocating jacking component is mounted on the mounting base 2, and the continuous hammering component is mounted on the reciprocating jacking component. The reciprocating jacking component includes a reciprocating jacking seat 29, a reciprocating jacking shaft 30, and a second gear 31. The reciprocating jacking seat 29 is a thick-walled tubular shape, and bearings 32 are fixedly fitted at both ends of the reciprocating jacking seat 29. The reciprocating jacking seat 29 is mounted on the mounting base 2 via the bearings 32, allowing the reciprocating jacking seat 29 to rotate circumferentially and lock axially on the mounting base 2. The reciprocating jacking shaft 30 is axially slidably embedded within the reciprocating jacking seat 29 tube, and the sliding block on the side wall of the reciprocating jacking shaft 30 is fitted into the sliding groove 33 on the inner wall of the reciprocating jacking seat 29. Furthermore, the sliding groove 33 is distributed along the axial direction on the inner wall of the reciprocating push seat 29 in a curved pattern, so as to push the reciprocating push shaft 30 to slide axially within the reciprocating push seat 29. When the reciprocating push seat 29 rotates 180 degrees circumferentially, it will drive the reciprocating push shaft 30 to move from the rightmost to the leftmost position. When the reciprocating push seat 29 continues to rotate to 360 degrees, it will drive the reciprocating push shaft 30 to move from the leftmost to the rightmost position. In this way, the reciprocating push seat 29 is rotated continuously in one direction, driving the reciprocating push shaft 30 to move axially back and forth. The second gear 31 is fixedly mounted on the outside of the reciprocating push seat 29, and the second gear 31 meshes with the first gear 24.

[0045] The continuous hammering component includes a hammering guide tube 34, a fourth spring 35, and a hammer 36. One end of the hammering guide tube 34 is axially slidably embedded in the other end tube of the abandoned chain pusher 26, and the other end face of the hammering guide tube 34 is fixedly connected to one end face of the reciprocating pusher shaft 30. The fourth spring 35 is embedded in the hammering guide tube 34, and one end of the fourth spring 35 is connected to the other end face of the hammering guide tube 34. The hammer 36 is cylindrical, axially slidably embedded in the hammering guide tube 34, and the hammer 36 is connected to the other end of the fourth spring 35. At the same time, the hammer 36 corresponds to one end of the abandoned chain pusher shaft 27.

[0046] The automatic chain-discarding device for anchor chains is used as follows: When it is necessary to actively discard the chain, the motor 23 is started, and the reciprocating push seat 29 is rotated through the first gear 24 and the second gear 31. The rotating reciprocating push seat 29 drives the hammer 36 to continuously hammer the reciprocating push shaft 30, thereby continuously pushing the anchor chain lock head 4 to the left through the reciprocating push shaft 30 to automatically discard the anchor chain 1.
