Description

Technical Field

[0001] This invention relates to the field of marine equipment technology, specifically to a multifunctional single-point mooring chain brake for ships. Background Technology

[0002] The guillotine chain catcher is the core equipment of a ship's anchoring system. It is mainly used to fix the anchor chain, transfer loads, and protect the anchor winch. Among them, the guillotine chain catcher is the most widely used in practice due to its compact structure, simple design, and convenient operation.

[0003] Over time, the contact points between the anchor chain and the chain catcher will gradually wear down due to friction and seawater corrosion, leading to an increase in the gap between them. When a gap appears, the chain catcher cannot effectively transfer the tension of the anchor chain to the hull structure, resulting in weakened braking force and potentially causing the ship to drag anchor.

[0004] Therefore, there is a need to provide a multifunctional single-point mooring chain chock for ships, which aims to solve the above problems. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a multifunctional single-point mooring chain stop for ships to solve the problems mentioned in the background.

[0006] To achieve the above objectives, the present invention provides the following technical solution: A multi-functional single-point mooring chain lock for ships, comprising: The chain stop is welded to the deck and a guide sprocket is rotatably connected to the chain stop. The guide sprocket has a guide groove. The stop assembly is rotatably connected to the chain stop seat and is used to brake the anchor chain; The distance adjustment component is slidably connected to the surface of the stop component and is used to adjust the distance between the stop component and the anchor chain; The locking assembly is engaged with the inside of one end of the stop assembly to secure the stop assembly. The deceleration component is slidably connected to the side of the stop component to reduce the vibration caused by the stop component when the anchor chain is closed.

[0007] As a preferred embodiment of the present invention, an anchor chain cylinder is installed on the deck, with one end of the anchor chain slidably connected to the inside of the anchor chain cylinder and the other end slidably connected to the surface of the guide groove.

[0008] As a preferred embodiment of the present invention, the stop assembly includes: a first support fixed to one side of the chain stop seat; and a chain stop knife rotatably connected to the first support, with an operating handle connected to its end.

[0009] As a preferred embodiment of the present invention, the adjusting assembly includes: an inverted U-shaped stop block slidably connected to the surface of the chain brake knife, with an inclined groove on its side; an extension seat fixed to the end of the inverted U-shaped stop block, with a through hole inside; a heat-conducting frame fixed to the upper surface of the chain brake knife, with the extension seat slidably connected to the surface of the heat-conducting frame; and a pin hole formed on the heat-conducting frame, with the heat-conducting frame and the through hole intermittently connected, and a pin engaging with the heat-conducting frame and the through hole.

[0010] As a preferred embodiment of the present invention, inclined grooves are provided on both sides of the C-shaped stop block.

[0011] As a preferred embodiment of the present invention, the pin-fixing assembly includes: a second support, fixed on the side of the chain stop away from the first support, with the end of the chain stop engaging inside the second support; a sliding pin, slidably connected inside the second support and to the end of the chain stop, with a handle vertically connected to the end of the sliding pin, and the handle and the second support connected by a spring; a handle groove, formed on the inner wall of the second support, with the end of the handle slidably connected inside the handle groove; an arc-shaped groove, formed on the inner side of the second support and communicating with the end of the handle groove, with the handle rotatably connected inside the arc-shaped groove; and an end bracket, fixed to the end of the second support, with the inner wall and the handle engaging.

[0012] As a preferred embodiment of the present invention, the deceleration assembly includes: a deceleration block slidably connected inside the chain brake, with its end connected to the inner wall of the chain brake via a compression spring; an oil chamber fixed inside the chain brake, with a piston slidably connected inside, and a flow channel formed on the piston; an inner groove formed on the side of the chain brake, with a sliding rod slidably connected inside, and the end of the sliding rod connected to the side of the piston; and a connecting rod, one end of which is hinged to the side of the deceleration block, and the other end of which is hinged to the end of the sliding rod.

[0013] As a preferred embodiment of the present invention, a flushing assembly is connected to the side of the chain stop seat. The flushing assembly is located on the upper side of the anchor chain cylinder and is used to flush the anchor chain inside the anchor chain cylinder. The flushing assembly includes: an arc-shaped tube fixed on the chain stop seat, with at least two sets of nozzles connected to the side of the arc-shaped tube; and an anchor chain tube connected to the outside of the chain stop seat, with one end connected to the arc-shaped tube and the other end connected to the output end of the self-priming pump.

[0014] Compared with the prior art, the embodiments of the present invention have the following beneficial effects: In the present invention, when it is observed that the gap between the anchor chain and the chain stop knife increases, by sliding the C-shaped stop block on the surface of the chain stop knife, the inclined groove on the side of the C-shaped stop block is always in close contact with the anchor chain, thereby achieving effective braking of the anchor chain.

[0015] Compared with the prior art, when the chain-locking knife is closed, the embodiments of the present invention can absorb and consume the energy of the anchor chain during the movement process through the preferential contact between the deceleration block and the anchor chain and the damping effect of the hydraulic oil, thereby reducing the impact force and vibration of the anchor chain and mitigating the danger caused by the closing of the switch when the anchor chain slides out at high speed. It has the characteristics of high stability and high safety.

[0026] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0027] The specific implementation of the present invention will be described in detail below with reference to specific embodiments.

[0028] See also Figures 1 to 8 A multi-functional single-point mooring chain tether for ships, comprising: Chain stop 11 is welded to deck 1. A guide wheel 12 is rotatably connected to the chain stop 11. A guide groove 121 is provided on the guide wheel 12. The stop assembly 2 is rotatably connected to the chain stop seat 11 and is used to brake the anchor chain 131; The distance adjustment component 3 is slidably connected to the surface of the stop component 2 and is used to adjust the distance between the stop component 2 and the anchor chain 131; The pin-locking component 4 is engaged inside one end of the stop component 2 to fix the stop component 2. The deceleration component 5 is slidably connected to the side of the stop component 2 to reduce the vibration caused by the stop component 2 when the anchor chain 131 is closed.

[0029] In one embodiment of the present invention, such as Figure 2 and Figure 4 As shown, the stop assembly 2 includes: The first support 21 is fixed to one side of the chain stop 11; The chain-operated knife gate 22 is rotatably connected inside the first support 21, and an operating handle 23 is connected to its end.

[0030] In this embodiment, an anchor chain cylinder 13 is installed on the deck 1. One end of the anchor chain 131 is slidably connected to the inside of the anchor chain cylinder 13, and the other end is slidably connected to the surface of the guide groove 121. The upper end of the anchor chain 131 is connected to the anchor winch, and the other end, passing through the anchor chain cylinder 13, is connected to the anchor claw. The anchor chain cylinder 13 serves as a channel for the anchor chain 131, ensuring smooth operation of the anchor chain 131 during anchoring and anchoring, and preventing collisions with other structures.

[0031] When anchoring, press down on the operating handle 23 to rotate the chain lock 22 upward on the first support 21, thereby opening the chain lock 22 and releasing the anchor chain 131. Use the anchor winch to slowly lower the anchor claws into the water. Once the anchor claws reach the bottom, stop anchoring. After anchoring is complete, immediately close the chain lock 22 to lock the anchor chain 131 and prevent it from slipping.

[0032] When anchoring, open the chain lock 22 to release the anchor chain 131, start the anchor winch, and slowly retract the anchor chain 131. After anchoring is completed, close the chain lock 22.

[0033] In one embodiment of the present invention, such as Figure 5 and Figure 6 As shown, the adjustment component 3 includes: The U-shaped stop block 31 is slidably connected to the surface of the chain gate 22, and inclined grooves 32 are provided on both sides; The extension seat 33 is fixed to the end of the U-shaped stop block 31 and has a through hole 36 inside; The heat conduction bracket 34 is fixed to the upper surface of the chain gate knife 22, and the extension seat 33 is slidably connected to the surface of the heat conduction bracket 34. A pin hole 35 is provided on the heat conduction frame 34. The heat conduction frame 34 and the through hole 36 are intermittently connected. A pin 37 is engaged and connected inside the heat conduction frame 34 and the through hole 36.

[0034] In this embodiment, a heat-conducting frame 34 is fixed on the surface of the chain gate 22. When the chain gate 22 generates a certain amount of heat due to frequent high loads, the heat-conducting frame 34 can achieve efficient heat dissipation of the chain gate 22.

[0035] During long-term use, the contact area between the anchor chain 131 and the chain brake 22 will gradually wear down due to friction and seawater corrosion, leading to an increase in the gap between them and the possibility of the ship dragging anchor. When the increased gap between the anchor chain 131 and the chain brake 22 is observed, the pin 37 is rotated to remove it from the pin hole 35 and through hole 36, thereby sliding the C-shaped stop block 31 on the surface of the chain brake 22. This allows the inclined groove 32 on the surface of the C-shaped stop block 31 to once again fit tightly against the anchor chain 131. Finally, the pin 37 is fixed inside the pin hole 35 and through hole 36, thus positioning the C-shaped stop block 31 on the chain brake 22. By sliding the C-shaped stop block 31 on the surface of the chain brake 22, the inclined groove 32 on the side of the C-shaped stop block 31 remains tightly fitted against the anchor chain 131, achieving effective braking of the anchor chain 131.

[0036] like Figure 6 As shown, the C-shaped stop block 31 has inclined grooves 32 on both sides. When the inclined groove 32 on one side of the C-shaped stop block 31 is deformed due to long-term contact and friction with the anchor chain 131, the shank 37 can be loosened and the C-shaped stop block 31 can be turned around on the chain brake 22. This allows the inclined groove 32 on the other side of the C-shaped stop block 31 to contact the anchor chain 131 and brake the anchor chain 131. This makes both inclined grooves 32 on both sides of the C-shaped stop block 31 usable, improving the utilization rate of the C-shaped stop block 31.

[0037] In one embodiment of the present invention, such as Figure 4 As shown, the pin-fixing assembly 4 includes: The second support 41 is fixed on the side of the chain stop 11 away from the first support 21, and the end of the chain stop 22 is engaged with the inside of the second support 41. A sliding pin 42 is slidably connected inside the second support 41 and the end of the chain gate 22. A handle 43 is vertically connected to the end of the sliding pin 42. The handle 43 and the second support 41 are connected by a spring 46. The handle groove 44 is formed on the inner wall of the second support 41, and the end of the handle 43 is slidably connected to the inside of the handle groove 44. An arc-shaped groove 45 is formed inside the second support 41 and communicates with the end of the handle groove 44. The handle 43 is rotatably connected inside the arc-shaped groove 45. The end bracket 47 is fixed to the end of the second support 41 and is engaged with the inner wall and the handle 43.

[0038] In this embodiment, when opening the chain gate 22, the handle 43 is first pushed towards the spring 46, causing the handle 43 to slide within the handle groove 44 until it is completely slid into the arc groove 45. After the handle 43 slides into the arc groove 45, the handle 43 is rotated, causing it to rotate 180 degrees within the arc groove 45 until it rotates out of the arc groove 45. At this time, the handle 43 will pull the sliding pin 42 to slide in the opposite direction within the second support 41 and the chain gate 22 under the force of the spring 46, until the end of the handle 43 slides to contact the inner wall of the end bracket 47. The handle 43 will then pull the sliding pin 42 at the other end to slide out of the end of the chain gate 22, thereby opening the chain gate 22.

[0039] After the chain gate 22 is closed, when it needs to be fixed, first push the handle 43 inward, so that the handle 43 drives the sliding pin 42 to slide towards the chain gate 22 within the second support 41, until the sliding pin 42 slides to the end of the chain gate 22, so that the chain gate 22 can position the sliding pin 42. When the handle 43 slides to the side of the arc groove 45, rotate the handle 43, so that the end of the handle 43 rotates into the inside of the arc groove 45. Since the arc groove 45 and the handle groove 44 are connected, release the handle 43, and the handle 43 will slide into the inside of the handle groove 44 under the force of the spring 46 (e.g., Figure 4 (in the closed state), the sliding pin 42 will be limited by the handle 43 and the handle groove 44, which improves the stability of the sliding pin 42 in fixing the chain gate 22 when the chain gate 22 is closed.

[0040] In one embodiment of the present invention, such as Figure 7 and Figure 8 As shown, the deceleration assembly 5 includes: The deceleration block 51 is slidably connected inside the chain brake 22, and its end is connected to the inner wall of the chain brake 22 through the compression spring 57. Oil chamber 53 is fixed inside the chain gate 22, and a piston 56 is slidably connected inside it. A flow channel 561 is opened on the piston 56. An embedded groove 52 is provided on the side of the chain gate 22, and a sliding rod 54 is slidably connected inside it. The end of the sliding rod 54 is connected to the side of the piston 56. The connecting rod 55 is hinged at one end to the side of the deceleration block 51 and at the other end to the end of the sliding rod 54.

[0041] In this embodiment, when the chain stop 22 is closed, the chain stop 22 will cause its lower deceleration block 51 to first contact the anchor chain 131. Under the impact of the anchor chain 131, the deceleration block 51 will slide into the chain stop 22, causing the deceleration block 51 to compress the compression spring 57 at its upper end. When the deceleration block 51 slides, it will push the sliding rod 54 to slide in the inner groove 52 through the connecting rod 55. The sliding rod 54 will push the piston 56 to slide in the oil chamber 53. During the process of the piston 56 sliding in the oil chamber 53, the hydraulic oil in the oil chamber 53 will flow through the flow channel 561, thereby slowing down the rapid sliding of the compression spring 57. When the chain stop 22 is closed, the preferential contact between the deceleration block 51 and the anchor chain 131 and the damping effect of the hydraulic oil can absorb and consume the energy of the anchor chain 131 during the movement, reduce the impact force and vibration of the anchor chain 131, reduce the impact on the chain stop, and mitigate the danger caused by closing the switch when the anchor chain 131 slides out at high speed (such as anchoring in a rapid current).

[0042] In one embodiment of the present invention, such as Figure 1 and Figure 2 As shown, a flushing assembly 6 is connected to the side of the chain holder 11. The flushing assembly 6 is located on the upper side of the anchor chain cylinder 13. The flushing assembly 6 is used to flush the anchor chain 131 inside the anchor chain cylinder 13. The flushing assembly 6 includes: An arc-shaped tube 61 is fixed on a chain seat 11, and at least two sets of nozzles 62 are connected to the side of the arc-shaped tube 61. Anchor chain pipe 63 is connected to the outside of chain seat 11. One end is connected to arc pipe 61, and the other end is connected to the output end of self-priming pump. The end of self-priming pump away from arc pipe 61 is connected to the bottom of the water through suction pipe.

[0043] In this embodiment, when anchoring, the self-priming pump is turned on, so that the self-priming pump can guide the anchor chain water into the arc-shaped pipe 61 through the anchor chain pipe 63, and spray it out through the nozzle 62 at the bottom of the arc-shaped pipe 61. In this way, the anchor chain 131 in the anchor chain cylinder 13 can be flushed during anchoring, reducing the accumulation of impurities on the surface of the anchor chain 131 and preventing seawater erosion.

[0044] The working principle of this invention is as follows: When anchoring, the chain stop 22 is opened to release the anchor chain 131 from fixation, the anchor winch is started, and the anchor chain 131 is slowly retracted. After anchoring is completed, the chain stop 22 is closed. When the chain stop 22 is closed, the chain stop 22 will drive the deceleration block 51 to contact the anchor chain 131. Under the impact of the anchor chain 131, the deceleration block 51 will slide into the chain stop 22, causing the deceleration block 51 to compress the compression spring 57 at its upper end. When the deceleration block 51 slides, it will push the sliding rod 54 to slide in the inner groove 52 through the connecting rod 55. The sliding rod 54 will push the piston 56 to slide in the oil chamber 53. During the process of the piston 56 sliding in the oil chamber 53, the hydraulic oil in the oil chamber 53 will flow through the flow channel 561, which can slow down the rapid sliding of the compression spring 57. Through the damping effect of the hydraulic oil, the energy of the anchor chain 131 during the movement can be absorbed and consumed, reducing the impact and vibration of the anchor chain 131, reducing the impact on the chain stopper, and mitigating the danger caused by the closing of the brake when the anchor chain 131 slides out at high speed.

[0045] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection, an electrical connection, or a connection that allows for communication; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.
