Description

Technical Field

[0001] This invention relates to the field of marine equipment technology, and more specifically, to a hydraulic stop mechanism for a marine turntable. Background Technology

[0002] In ship navigation and berthing operations, the turntable used for winding ropes is one of the core pieces of equipment. It is mainly used for winding, unwinding, and securing ropes during ship mooring and towing operations. Large ships' turntables, which need to wind large-diameter ropes, often weigh tens or even hundreds of tons, have extremely high rotational inertia. Therefore, a fast and reliable stopping mechanism is required during operation to control the start and stop of the turntable, ensuring operational safety and precise control.

[0003] Currently, the stopping mechanisms of marine turntables are mainly divided into two categories: mechanical braking and hydraulic braking. However, both have obvious defects: First, the stopping effect is poor. Mechanical braking mechanisms rely on the friction between the brake pads and the brake disc to achieve stopping. However, for high-inertia turntables, the braking torque of a single or a small number of brake pads is insufficient, which easily leads to slippage and makes it impossible to brake the turntable quickly. Moreover, uneven force during braking may cause deformation of the turntable. Second, the stability is poor. The thrust transmission structure of traditional hydraulic braking mechanisms is poorly designed, and the movement direction of the brake pads is prone to deviation, affecting braking accuracy. Furthermore, the brake pads wear unevenly after long-term use, further reducing the reliability of stopping. Third, maintenance is inconvenient. The brake pads of existing mechanisms are mostly fixedly installed. Disassembly and replacement require the removal of a large number of parts, which is cumbersome. In addition, there is a lack of effective wear and temperature monitoring mechanisms, which makes it impossible to detect excessive wear of the brake pads or overheating problems in time, posing safety hazards.

[0004] To address the aforementioned pain points, the industry urgently needs a marine turntable hydraulic stop mechanism that offers stable braking, convenient maintenance, and strong adaptability. By optimizing the structural design, the core problem of the difficulty in stopping high-inertia turntable components can be solved, while simultaneously enabling real-time monitoring of the brake block status, thus providing reliable assurance for the safety of ship operations. Summary of the Invention

[0005] The present invention aims to solve the problem of large tonnage, large rotational inertia, and difficulty in stopping large ship turntable components.

[0006] To address the aforementioned problems, this invention provides a hydraulic stop mechanism for a marine turntable, used to stop a turntable component in a ship's hull used for winding ropes. It includes a brake disc fixedly mounted on the outside of the turntable component. Brake blocks, evenly spaced and arranged in a ring, are movably mounted on the outside of the turntable component, with the side of the brake blocks facing the brake disc engaging with it. A mounting bracket, fixed to the hull and corresponding to the brake blocks, is also provided on the outside of the turntable component. Symmetrically distributed inclined push blocks are movably mounted within the mounting bracket. Symmetrically distributed guide rails are fixedly mounted on the side of each brake block near the inclined push block. The outer wall of each inclined push block has a guide groove for receiving the guide rails. The mechanism further includes: a displacement mechanism located on both sides of the mounting bracket for pushing the inclined push blocks within the mounting bracket; and a limiting mechanism located within the inclined push blocks for confining the brake blocks to one side of the inclined push blocks and pushing the brake blocks towards the brake disc when the inclined push blocks move.

[0007] The present invention provides a hydraulic stop mechanism for a marine turntable, which, compared with the prior art, has, but is not limited to, the following beneficial effects: Addressing the challenges of large tonnage, high rotational inertia, and difficulty in stopping turntable components on large vessels, this mechanism employs a brake disc welded and fixed to the outside of the turntable component. Six brake blocks are arranged in a ring around the outside of the turntable component. The mounting bracket is fixed to the hull deck using expansion bolts. During installation, the inclined push block is movably installed within the mounting bracket, and the guide rails of the brake blocks are embedded in the guide grooves of the inclined push block, achieving rapid positioning of the brake blocks. Then, a limiting mechanism can confine the brake blocks to one side of the inclined push block. Displacement mechanisms are installed on both sides of the mounting bracket; when the turntable component needs to be stopped, the displacement mechanism... The shifting mechanism drives the inclined push block to move along the mounting frame. The guide groove and the inclined surface of the guide rail cooperate to generate radial thrust, which pushes the brake block towards the brake disc and presses it. The friction force counteracts the inertia of the turntable, thus achieving a stop. The limiting mechanism restricts the brake block to one side of the inclined push block to prevent it from falling off during movement. The six brake blocks work together to provide uniform stopping torque, which can quickly brake high-tonnage turntables without slippage. When the brake blocks are worn, the limiting mechanism can be released to restrict the brake blocks, and they can be removed and replaced, making it very convenient to use.

[0008] Furthermore, the displacement mechanism includes a fixed frame fixedly installed on both sides of the mounting bracket, and a hydraulic cylinder is fixedly installed in the fixed frame. The telescopic end of the hydraulic cylinder is fixedly connected to the side wall of the inclined push block.

[0009] Furthermore, the limiting mechanism includes a sliding plate, and a groove is provided on the inner side of the guide rail. The sliding plate is slidably disposed in the groove. A locking component is also provided below the sliding plate to lock the sliding plate to one side of the inclined push block.

[0010] Furthermore, the locking assembly includes a locking plate fixedly disposed on one side of the slide plate, a locking groove is provided on the side of the inclined push block near the slide plate, and the locking plate is located in the locking groove. A locking hole is provided on the outer wall of the locking plate, and an insert plate is provided through the outer side of the inclined push block. A locking handle is fixedly installed at the end of the insert plate, and the insert plate passes through the locking hole.

[0011] Furthermore, a handle is fixedly installed at the end of the skateboard.

[0012] Furthermore, it also includes a guide mechanism, which is disposed between the brake block and the mounting bracket to limit the direction of movement of the brake block so that it can only move vertically toward the brake disc.

[0013] Furthermore, the guiding mechanism includes a sleeve fixedly installed in the mounting bracket, a sleeve rod movably installed in the sleeve, and a side plate fixedly installed at the end of the sleeve rod, the side plate being fixedly installed on the outside of the inclined push block.

[0014] Furthermore, the outer wall of the brake block is provided with equally spaced mounting openings, and a temperature sensor is installed in the mounting opening to detect the temperature of the brake block.

[0015] Furthermore, a detection mechanism is also provided in the mounting port for detecting the wear degree of the brake pads.

[0016] Furthermore, the detection mechanism includes a trigger switch and a contact rod. The contact rod is fixedly installed at both ends of the trigger switch. A detection groove is provided on the inner wall of the mounting port facing the brake disc, and the end of the contact rod is located in the detection groove. A screw is also rotatably provided on the outer wall of the trigger switch. A threaded groove is provided on the inner wall of the mounting port, and the screw is threadedly connected to the threaded groove. Attached Figure Description

[0027] See Figures 1-9 This invention discloses a hydraulic stop mechanism for a marine turntable, used to stop a turntable component 1 used for winding ropes in a ship's hull. The mechanism includes a brake disc 11 fixedly disposed on the outside of the turntable component 1. Brake blocks 2 are movably disposed on the outside of the turntable component 1, arranged in a ring at equal intervals. The side of the brake blocks 2 facing the brake disc 11 engages with the brake disc 11. A mounting bracket 3, fixed to the hull and corresponding to the brake blocks 2, is also disposed on the outside of the turntable component 1. Symmetrically distributed oblique... The push block 4 has symmetrically distributed guide rails 21 fixedly installed on the side of the brake block 2 near the inclined push block 4. The outer wall of the inclined push block 4 has a guide groove 41 for receiving the guide rails 21. It also includes: a displacement mechanism 5, which is disposed on both sides of the mounting frame 3 and is used to push the inclined push block 4 to move in the mounting frame 3; and a limiting mechanism 6, which is disposed in the inclined push block 4 and is used to limit the brake block 2 to one side of the inclined push block 4 and push the brake block 2 toward the brake disc 11 when the inclined push block 4 moves.

[0028] In this embodiment, addressing the problem of large tonnage, high rotational inertia, and difficulty in stopping the turntable component 1 of a large ship, the brake disc 11 in this mechanism is welded and fixed to the outside of the turntable component 1. Six brake blocks 2 are distributed in a ring on the outside of the turntable component 1. The mounting bracket 3 is fixed to the ship's deck by expansion bolts. During installation, the inclined push block 4 is movably installed in the mounting bracket 3. The guide rail 21 of the brake block 2 is embedded in the guide groove 41 of the inclined push block 4, achieving rapid positioning of the brake block 2. Then, the limiting mechanism 6 can restrict the brake block 2 to one side of the inclined push block 4. The displacement mechanism 5 is installed on both sides of the mounting bracket 3. The turntable component 1 needs to... When stopped, the displacement mechanism 5 drives the inclined push block 4 to move along the mounting bracket 3. The guide groove 41 cooperates with the inclined surface of the guide rail 21 to generate radial thrust, which pushes the brake block 2 toward the brake disc 11 and presses it. The friction force counteracts the inertia of the turntable 1, thus achieving the stop. The limiting mechanism 6 restricts the brake block 2 to one side of the inclined push block 4 to prevent it from falling off during movement. The six brake blocks 2 work together to generate uniform stopping torque, which can quickly brake the high-tonnage turntable without slippage. When the brake block 2 is worn, the limiting mechanism 6 can be released to restrict the brake block 2, and it can be removed and replaced, which is very convenient to use.

[0029] Optional, please refer to Figure 2 The displacement mechanism 5 includes a fixed frame 51 fixedly installed on both sides of the mounting frame 3. A hydraulic cylinder 52 is fixedly installed in the fixed frame 51. The telescopic end of the hydraulic cylinder 52 is fixedly connected to the side wall of the inclined push block 4.

[0030] In this embodiment, the fixed frame 51 is welded to both sides of the mounting bracket 3, and the hydraulic cylinder 52 is fixed inside the fixed frame 51 by a flange. The telescopic end of the hydraulic cylinder 52 is fixedly connected to the side wall of the inclined push block 4 by a pin, and the hydraulic pipeline is connected to the hull hydraulic system. The hull hydraulic system provides high-pressure oil to drive the hydraulic cylinder 52 to extend and retract, pushing the inclined push block 4 to move horizontally along the mounting bracket 3, providing a strong thrust for the brake block 2 to press against the brake disc 11. After the stop is completed, the hydraulic cylinder 52 extends and retracts in the opposite direction, driving the inclined push block 4 to reset, and the brake block 2 disengages from the brake disc 11, meeting the stop requirements of the large tonnage turntable. The extension and retraction speed is stable, and the drive response time is ≤0.2 seconds, ensuring rapid stop.

[0031] Optional, please refer to Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 The limiting mechanism 6 includes a sliding plate 62, and a groove 61 is provided on the inner side of the guide rail 21. The sliding plate 62 is slidably disposed in the groove 61. A locking component is also provided below the sliding plate 62 to lock the sliding plate 62 to one side of the inclined push block 4.

[0032] In this embodiment, a rectangular groove 61 is provided on the inner side of the guide rail 21. The slide plate 62 is slidably embedded in the groove 61. One side of the slide plate 62 is in contact with the inner wall of the inclined push block 4. The locking component is installed below the slide plate 62 to lock the slide plate 62 and the inclined push block 4. During assembly, the slide plate 62 is inserted along the groove 61 to initially position the brake block 2 and the inclined push block 4. After locking by the locking component, it is ensured that when the inclined push block 4 moves, the brake block 2 only moves along the inclined surface of the guide groove 41, and the brake block 2 is prevented from disengaging from the inclined push block 4, making the use more stable.

[0033] Optional, please refer to Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 9 The locking assembly includes a locking plate 65 fixedly disposed on one side of the slide plate 62. The inclined push block 4 has a locking groove 64 on the side near the slide plate 62, and the locking plate 65 is located in the locking groove 64. The outer wall of the locking plate 65 has a locking hole 66. An insert plate 67 is provided through the outer side of the inclined push block 4. A locking handle 68 is fixedly installed at the end of the insert plate 67, and the insert plate 67 passes through the locking hole 66.

[0034] In this embodiment, the locking plate 65 is welded to one side of the sliding plate 62, and the locking groove 64 is opened at the corresponding position of the inclined push block 4. After the locking plate 65 is inserted into the locking groove 64, the insert plate 67 passes through the locking hole 66 from the outside of the inclined push block 4. The locking handle 68 is fixed to the end of the insert plate 67 for easy operation of the insert plate 67. During operation, when the sliding plate 62 is in place, the locking plate 65 is embedded in the locking groove 64, and the insert plate 67 is inserted through the locking hole 66 to achieve mechanical locking between the sliding plate 62 and the inclined push block 4. During disassembly, the locking handle 68 is pulled out to remove the insert plate 67, and the sliding plate 62 can be slid away from the inclined push block 4 to remove the brake block 2, making it more convenient to use.

[0035] Optional, please refer to Figure 8 A handle 63 is also fixedly installed at the end of the skateboard 62.

[0036] In this embodiment, the handle 63 is a cylindrical structure, welded and fixed to the exposed end of the slide plate 62, and has anti-slip texture on its surface; when assembling or disassembling the slide plate 62, the operator can easily pull the slide plate 62 along the slide groove 61 by holding the handle 63, without the need for additional tools.

[0037] Optional, please refer to Figure 2 , Figure 3 and Figure 5It also includes a guide mechanism 7, which is disposed between the brake block 2 and the mounting bracket 3 to limit the movement direction of the brake block 2 so that it can only move vertically toward the brake disc 11. The guide mechanism 7 includes a sleeve 72 fixedly installed in the mounting bracket 3. A sleeve rod 73 is movably installed in the sleeve 72, and a side plate 71 is fixedly installed at the end of the sleeve rod 73. The side plate 71 is fixedly installed on the outside of the inclined push block 4.

[0038] In this embodiment, the guide mechanism 7 is symmetrically distributed on both sides of each brake block 2. The sleeve 72 is welded and fixed to the inner wall of the mounting bracket 3. One end of the sleeve rod 73 is welded to the side plate 71. The side plate 71 is fixed to the outside of the inclined push block 4 by bolts. The sleeve rod 73 is movably inserted into the sleeve 72. When the inclined push block 4 moves, it drives the sleeve rod 73 to slide along the axial direction of the sleeve 72, limiting the inclined push block 4 to move only in the horizontal direction, thereby ensuring that the brake block 2 moves only vertically toward the brake disc 11, avoiding deviation and achieving better performance.

[0039] Optional, please refer to Figure 3 The outer wall of the brake block 2 is also provided with equally spaced mounting openings 22, and a temperature sensor is provided in the mounting opening 22 to detect the temperature of the brake block 2.

[0040] In this embodiment, the mounting port 22 is opened on the side of the brake block 2. The temperature sensor is fixed in the mounting port 22 by threads, and the probe is inserted into the interior of the brake block 2. The signal cable is connected to the ship's central control system. When the brake block 2 and the brake disc 11 rub against each other and generate high temperature, the temperature sensor collects temperature data in real time and transmits it to the central control system. When the temperature exceeds 200°C, the system issues a high temperature warning.

[0041] Optional, please refer to Figure 3 and Figure 4 The mounting port 22 is also provided with a detection mechanism 8 for detecting the wear degree of the brake block 2. The detection mechanism 8 includes a trigger switch 82 and a contact rod 84. The contact rod 84 is fixedly installed at both ends of the trigger switch 82. A detection groove 81 is opened on the inner wall of the mounting port 22 facing the brake disc 11, and the end of the contact rod 84 is located in the detection groove 81. A screw 83 is rotatably provided on the outer wall of the trigger switch 82. A threaded groove is opened on the inner wall of the mounting port 22, and the screw 83 is threadedly connected to the threaded groove.

[0042] In this embodiment, the detection groove 81 is opened on the side of the mounting port 22 facing the brake disc 11. The end of the contact rod 84 extends into the detection groove 81. The trigger switch 82 is fixed inside the mounting port 22. The signal cable is connected to the central control system. By rotating the screw 83, the trigger switch 82 and the contact rod 84 can be moved to control the length of the contact rod 84 extending into the detection groove 81, thereby modulating the wear alarm threshold. After long-term use, the brake pad 2 gradually wears down. When the wear reaches the set value, the end of the contact rod 84 will directly contact the brake disc 11, forming a closed loop between the brake disc 11, the contact rod 84, and the trigger switch 82. This causes the trigger switch 82 to activate and send a wear warning signal to the central control system, prompting the replacement of the brake pad 2. This effectively provides early warning of excessive wear of the brake pad 2, avoiding stopping failures caused by brake pad 2 failure, reducing safety risks, and making the use safer.

[0043] While the present invention has been disclosed above, its scope of protection is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the scope of protection of the present invention.
