Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of chain stopper, and particularly relates to a chain stopper for a ship. BACKGROUND

[0002] When a ship is anchored, the anchor chain is anchored on the seabed, and then the ship is pulled through the anchor chain. When the ship is sailing or the anchor chain is not needed, the anchor chain is usually locked by the chain stopper, and the anchor chain is stored in the anchor chain locker. When the anchor is thrown, the anchor chain is pulled down into the sea by the anchor windlass.

[0003] The prior art also provides some solutions, such as a chain stopper base disclosed in a Chinese patent application with the announcement number CN216783773U. The chain stopper base is arranged on a ship, and the ship comprises a deck. A reinforcing structure is arranged at the lower end of the deck. The chain stopper base comprises a base body. The base body is arranged on the deck and corresponds to the reinforcing structure. The base body is used for supporting the chain stopper. A first connecting hole is arranged on the chain stopper. When the ship is in the stage of small section closing, the base body is installed on the deck at a position corresponding to the reinforcing structure. Then, the chain stopper is installed on the chain stopper base. The first connecting hole and the second connecting hole are connected through the connecting piece. The dislocation of the chain stopper and the reinforcing structure under the deck is avoided. The process of cutting and repeated welding on site is avoided. The installation efficiency is effectively improved.

[0004] The above technical solution avoids the dislocation of the chain stopper and the reinforcing structure under the deck. However, other problems still exist in use. For example, when the anchor chain is locked by the chain stopper, a single brake blade or a clamp block is currently used to lock the anchor chain. When the anchor chain is subjected to a large impact force, the single brake blade or the clamp block may be separated from the anchor chain due to the large pulling force.

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0023] like Figures 1 to 8 As shown in the embodiment of the present invention, a ship chain stop includes a hull frame 1. A chain stop base 2 is mounted on the surface of the hull frame 1. A guide wheel 3 is rotatably arranged inside the chain stop base 2. A guide groove 301 is formed on the surface of the guide wheel 3. An anchor chain 4 is arranged on the surface of the guide wheel 3. A fixing frame 5 is mounted above the chain stop base 2. A rotating horizontal shaft 501 is rotatably arranged on the inner side of the fixing frame 5. The end of the rotating horizontal shaft 501 is connected to the output end of a motor. A gate holder 6 is fixedly mounted on the outer circumference of the rotating horizontal shaft 501. A plurality of locking rods 701 are arranged below the gate holder 6. The plurality of locking rods 701 are used to cooperate with the gaps of the horizontal chain links at different positions of the anchor chain 4 and to lock the anchor chain 4. During operation, once the anchor is dropped and reaches the predetermined chain length, the anchor winch brake first initially brakes the anchor chain 4. Then, it controls the rotation of the knife block 6, causing the knife block 6 to rotate towards the side closer to the anchor chain 4. This controls the motor to drive the rotating horizontal shaft 501 to rotate, causing the rotating horizontal shaft 501 to drive the knife block 6 and the clamping rod 701 to rotate towards the side closer to the anchor chain 4. Then, the clamping rods 701 at different positions will lock into the gaps of the anchor chain 4 links at different locations, thus braking the anchor chain 4. In this way, compared to the huge tensile force originally borne by a single knife block or clamping block, it is distributed to multiple support points, reducing the load on individual components and improving the overall service life of the chain brake. Moreover, when the ship anchors, the weight of the anchor and anchor chain 4, as well as the impact force caused by wind, waves and currents, are enormous. The chain catcher firmly fixes the anchor chain 4 through its robust mechanical structure. This force is then directly transmitted to the reinforced structure of the ship's deck through the base of the chain catcher, thus bypassing the anchor winch, which is precisely manufactured but has limited load-bearing capacity.

[0024] The end of the shutter holder 6 away from the rotating horizontal shaft 501 is provided with a matching plate 7, the lower end surface of the matching plate 7 is provided with an adjusting unit, and the adjusting unit is used for adjusting the position of the clamping rod 701; In operation, when the anchor chain 4 needs to be stopped, the rotating horizontal shaft 501 is driven to rotate by the control motor, and the shutter holder 6 is driven to rotate towards the side close to the anchor chain 4, and then the shutter holder 6 drives the matching plate 7 to press on the surface of the anchor chain 4. Through the action of the adjusting unit, the clamping rod 701 at different positions can be adjusted to cooperate with the horizontal link gap of the anchor chain 4, and the anchor chain 4 is fixed by the clamping rod 701 at different positions. Compared with the original single shutter or clamping block bearing the huge tension, the load of a single component is reduced.

[0025] The adjusting unit comprises an L-shaped support 8, the side wall of the L-shaped support 8 is provided with an electric push rod 9, the telescopic end of the electric push rod 9 is fixedly provided with a rectangular block 10, the rectangular block 10 is slidably arranged on the lower end surface of the matching plate 7, and the clamping rod 701 is arranged on the lower end surface of the rectangular block 10. In operation, when the shutter holder 6 rotates towards the side close to the anchor chain 4 and cooperates with the horizontal link gap of the anchor chain 4, if the clamping rod 701 cannot completely cooperate with the horizontal link gap of the anchor chain 4, the telescopic end of the electric push rod 9 on the side wall of the L-shaped support 8 is moved to drive the rectangular block 10 and the clamping rod 701 to move until the clamping rod 701 is clamped into the corresponding horizontal link gap of the anchor chain 4. Through the above design, the gap between the clamping rod 701 and the anchor chain 4 can be accurately controlled. When the anchor chain 4 is elongated due to stretching or the size of the link is different, the entire device does not need to be replaced, and the position of the clamping rod 701 only needs to be adjusted to obtain tight cooperation again, thereby ensuring effective locking.

[0026] The lower end surface of the rectangular block 10 is provided with an L-shaped support shaft 11, the clamping rod 701 is rotatably arranged on the inner side of the L-shaped support shaft 11, and the surface of the rectangular block 10 is provided with a circular groove matched with the clamping rod 701. In operation, when the electric push rod 9 controls the movement of the rectangular block 10 and the clamping rod 701, the clamping rod 701 can also be controlled to rotate on the surface of the L-shaped support shaft 11 to adjust the angle of the clamping rod 701, so that the clamping rod 701 can be better clamped into different horizontal link gaps of the anchor chain 4, and the operation is more convenient, which is beneficial to the locking of the anchor chain 4.

[0027] The surface of the matching plate 7 is provided with a plurality of vertical grooves 12, the upper end surface of the rectangular block 10 is provided with a butt joint groove, the surface of the matching plate 7 is provided with a latch 121, and the latch 121 is used for being inserted into the vertical groove 12 and deep into the butt joint groove in the upper end surface of the rectangular block 10. When the card rod 701 is clamped into the gap between the chain links of the anchor chain 4, the rectangular block 10 no longer moves, and the worker can insert the latch 121 on the surface of the fitting plate 7 into the docking groove on the upper end surface of the rectangular block 10 through the vertical slot 12, that is, the rectangular block 10 can be fixed, so that the rectangular block 10 and the fitting plate 7 are integrated, so that the impact force of the wind and waves on the chain stopper base is directly transmitted to the reinforced structure of the ship deck, which has a certain protective effect on the electric push rod 9 and improves its service life.

[0028] The end of the rotating horizontal shaft 501 is provided with a gear 13, the inside of the chain stopper base 2 is slidably provided with a toothed plate 14, the toothed plate 14 and the gear 13 are connected in meshing, the end of the toothed plate 14 is provided with a connecting frame 15, and the end of the connecting frame 15 away from the toothed plate 14 is provided with a clamping column 16. When the rotating horizontal shaft 501 drives the shutter frame 6 to rotate towards the side close to the anchor chain 4, the rotating horizontal shaft 501 will simultaneously drive the gear 13 at the end thereof to rotate, and since the gear 13 and the toothed plate 14 are connected in meshing, the gear 13 will drive the toothed plate 14 to move, and the toothed plate 14 will drive the connecting frame 15 to move towards the side close to the anchor chain 4, and the connecting frame 15 will drive the clamping column 16 to be further clamped in the vertical chain link gap of the anchor chain 4. In this way, the card rod 701 can be clamped to the horizontal chain link, and the clamping column 16 can be clamped to the vertical chain link, thereby achieving a double insurance effect. This dispersed force reduces the pressure of each contact point, so that the anchor chain 4 can be more smoothly and reliably stopped, and the risk of damage to the anchor chain 4 or the chain stopper itself due to stress concentration under a large impact force is reduced. It should be noted that the same adjusting unit as the above-mentioned card rod 701 is arranged on the side wall of the connecting frame 15, that is, the function of the clamping column 16 is the same as that of the card rod 701, that is, the position of the card rod 701 can be adjusted according to the position of the anchor chain 4.

[0029] The inside of the chain stopper base 2 is provided with a sliding groove matched with the toothed plate 14, and the diameter of the clamping column 16 is smaller than the length of the chain link gap of the anchor chain 4. The upper end surface of the shutter frame 6 is provided with a connecting support frame 702, the side of the connecting support frame 702 away from the shutter frame 6 is provided with a ratchet frame 17, the surface of the chain stopper base 2 is provided with a clamping groove 18, the inside of the clamping groove 18 is provided with a clamping unit, and the clamping unit is used to cooperate with the ratchet frame 17 and fix the shutter frame 6. When the shutter frame 6 rotates towards the side close to the anchor chain 4, the shutter frame 6 will simultaneously drive the connecting support frame 702 to rotate, the connecting support frame 702 drives the ratchet frame 17 to move towards the inside of the clamping groove 18, and then the ratchet frame 17 cooperates with the clamping unit in the inside of the clamping groove 18 to make the clamping unit tightly clamp the ratchet frame 17, so as to further improve the stability of the shutter frame 6 and improve the safety.

[0030] The engaging unit comprises a ratchet wheel 19 rotatably arranged inside the clamping groove 18, a deflection rod 20 rotatably mounted on the side wall of the ratchet frame 17, an end of the deflection rod 20 being mounted with a ratchet rod 21, and the deflection rod 20 being controlled to rotate by a controller, and the shape of the ratchet frame 17 being matched with the shape of the clamping groove 18; in operation, when the ratchet frame 17 is deeply inserted into the clamping groove 18, the deflection rod 20 is driven to rotate by the controller, the ratchet rod 21 is driven to rotate by the deflection rod 20, and then the ratchet rod 21 is clamped on the ratchet teeth on the surface of the ratchet wheel 19, so that the stability of the shutter frame 6 is improved under the mutual clamping of the ratchet rod 21 and the ratchet wheel 19, which is beneficial to the braking of the anchor chain 4.

[0031] In operation, when the anchor is thrown and reaches the predetermined chain length, the anchor windlass brake first preliminarily brakes the anchor chain 4, then the shutter frame 6 is controlled to rotate, so that the shutter frame 6 rotates to the side close to the anchor chain 4, i.e. the rotating horizontal shaft 501 is driven to rotate by the control motor, so that the shutter frame 6 and the clamping rods 701 are driven to rotate to the side close to the anchor chain 4, then the clamping rods 701 at different positions are clamped in the chain link gaps at different positions of the anchor chain 4, i.e. the anchor chain 4 is braked, so that the huge pulling force originally borne by a single shutter or clamp block is dispersed to multiple support points, the load of a single component is reduced, and the overall service life of the chain stopper is improved. Moreover, when the ship is anchored, the gravity of the anchor and the anchor chain 4 and the impact force caused by wind and waves are huge, the chain stopper firmly fixes the anchor chain 4 through its solid mechanical structure, and this force is then directly transmitted to the reinforced structure of the ship deck through the base of the chain stopper, so as to bypass the anchor windlass which is precise in manufacturing but limited in bearing capacity; when it is necessary to brake the anchor chain 4, the rotating horizontal shaft 501 is driven to rotate by the control motor at this time, the shutter frame 6 is driven to rotate to the side close to the anchor chain 4, then the shutter frame 6 drives the abutting plate 7 to press on the surface of the anchor chain 4, and through the action of the adjusting unit, the clamping rods 701 at different positions can be adjusted to cooperate with the horizontal chain link gaps of the anchor chain 4, and the anchor chain 4 is fixed by the clamping rods 701 at different positions; When the shutter frame 6 rotates to the side close to the anchor chain 4 and cooperates with the horizontal link gap of the anchor chain 4, if the clamping rod 701 cannot fully cooperate with the horizontal link gap of the anchor chain 4, the telescopic end of the electric push rod 9 controlled by the side wall of the L-shaped support frame 8 is moved, so that the telescopic end of the electric push rod 9 drives the rectangular block 10 and the clamping rod 701 to move, until the clamping rod 701 is clamped into the corresponding horizontal link gap of the anchor chain 4. This design can accurately control the gap between the clamping rod 701 and the anchor chain 4. When the anchor chain 4 is stretched and lengthened or the size of the link is different, the entire device does not need to be replaced, and the clamping rod 701 only needs to be adjusted to reobtain tight cooperation and ensure effective locking. When the electric push rod 9 controls the movement of the rectangular block 10 and the clamping rod 701, the clamping rod 701 can also be adjusted in angle on the surface of the L-shaped support shaft 11, so that the clamping rod 701 can be better clamped into different horizontal link gaps of the anchor chain 4, which is convenient to operate and is beneficial to the locking of the anchor chain 4. When the clamping rod 701 is clamped into the corresponding link gap of the anchor chain 4, the rectangular block 10 no longer moves, and the worker can insert the latch 121 on the surface of the fitting plate 7 into the butt joint groove on the upper end surface of the rectangular block 10 through the vertical slot 12, so as to fix the rectangular block 10, so that the rectangular block 10 and the fitting plate 7 are integrated. This can make the impact force of the wind and wave directly transmitted to the reinforced structure of the ship deck, and has a certain protective effect on the electric push rod 9, thereby improving the service life of the electric push rod 9. When the rotating horizontal shaft 501 drives the shutter frame 6 to rotate to the side close to the anchor chain 4, the rotating horizontal shaft 501 will also drive the gear 13 at the end thereof to rotate. Since the gear 13 and the toothed plate 14 are engaged and connected, the gear 13 will drive the toothed plate 14 to move, and the toothed plate 14 will drive the connecting frame 15 to move to the side close to the anchor chain 4. The connecting frame 15 will drive the clamping column 16 to be further clamped in the vertical link gap of the anchor chain 4. This design can clamp the horizontal link by the clamping rod 701 and clamp the vertical link by the clamping column 16, which has a secondary safety effect. The dispersed force reduces the pressure of each contact point, so that the anchor chain 4 can be stopped more stably and reliably, and the risk of damage to the anchor chain 4 or the chain stopper itself due to stress concentration under a large impact force is reduced. When the shutter frame 6 rotates to the side close to the anchor chain 4, the shutter frame 6 will drive the connecting support frame 702 to rotate, the connecting support frame 702 drives the ratchet frame 17 to move close to the inside of the clamping groove 18, then the ratchet frame 17 cooperates with the clamping unit inside the clamping groove 18, so that the clamping unit clamps the ratchet frame 17, so as to further improve the stability of the shutter frame 6, and the safety is high; when the ratchet frame 17 is deeply inserted into the inside of the clamping groove 18, the deflection rod 20 is driven to rotate by the controller, the ratchet rod 21 is driven to rotate by the deflection rod 20, then the ratchet rod 21 is clamped on the ratchet on the surface of the ratchet wheel 19, so that under the mutual clamping of the ratchet rod 21 and the ratchet wheel 19, the stability of the shutter frame 6 is improved, which is beneficial to the braking of the anchor chain 4.
