Description

Technical Field

[0001] The present invention relates to the technical field of slide rail cable bolts, and in particular to an adjustable marine slide rail cable bolt and a locking method thereof. Background Art

[0002] A slide rail cable bolt is a mechanical structure combining a slide rail and a locking device, usually used for fixing or moving an object. It includes a sliding guide rail part and a locking bolt structure, mainly used for moving on the track and locking at a specific position. The main function of the slide rail cable bolt is to provide smooth sliding on the track and be able to fix the sliding component at the required position through the locking device when needed. The design of the slide rail cable bolt can be applied to various scenarios, such as ship mooring systems, fixing of industrial equipment, positioning of mechanical components, etc. Through this design combining sliding and locking, the slide rail cable bolt can provide flexibility during the sliding process, while ensuring sufficient stability when locked to prevent unnecessary movement or displacement.

[0003] Existing cable bolt products, whether made of stainless steel or die-cast aluminum, have the same limitation, that is, these cable bolts are usually fixedly installed at a certain position on the hull and cannot be adjusted flexibly, resulting in inconvenience in use. Since these cable bolts cannot be changed in position according to actual needs, the ship must anticipate the mooring position and direction in advance when docking. Especially in a complex seaport or dock environment, the operation is more difficult. The ship may need to adjust repeatedly according to the conditions of a specific docking point, increasing the workload of the crew and reducing the efficiency and safety of mooring. The cable bolts with fixed positions cannot adapt to the changes in different mooring situations, restricting the flexibility of the ship. Especially in the case of strong winds and waves, the position of the hull cannot be adjusted flexibly, which is prone to danger. In addition, the fixity of the cable bolts also restricts the ship's ability to respond quickly in various environments and cannot meet the increasingly complex navigation needs, making the mooring operation more cumbersome and time-consuming. Therefore, the present application provides an adjustable marine slide rail cable bolt and a locking method thereof to meet the adjustability of the cable bolt during use. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide an adjustable marine slide rail cable bolt and a locking method thereof to solve the problem that the position of the cable bolt cannot be changed according to the actual use position, resulting in the need to adjust the docking position and direction in advance in some places, and the inconvenience of mooring.

At the bottom of the two positioning blocks, a connecting rod is fixedly connected. The top of the sliding positioning pin is rotatably connected with the top of a number of the connecting rods.

[0009] Preferably, one side of the positioning handle is arranged in a hollowed-out manner. There is a gap between the bottom of the hollowed-out side of the positioning handle and the bottom surface of the positioning plate.

[0010] Preferably, the lubricating component includes a slide rail lubricating grease storage bin fixedly installed inside the other side of the cable bolt body. A positioning cylinder is fixedly installed inside the slide rail lubricating grease storage bin. An oil outlet cavity is arranged between the slide rail lubricating grease storage bin and the positioning cylinder. Above the oil outlet cavity, a number of lubricating ports are provided. The lubricating ports are used for discharging lubricating liquid or lubricating grease.

[0011] Preferably, a fixing column is axially installed in the middle of the inner side of the positioning cylinder. An oil storage cavity is arranged between the outer wall of the fixing column and the inner wall of the positioning cylinder. The fixing column is hollow. On one side of the inner wall of the fixing column, an oil injection hole is provided. The oil injection hole is used for supplementing and injecting lubricating grease. A number of groups of oil outlet holes are provided on the side wall of the positioning cylinder. The number of groups of the oil outlet holes is used for discharging the lubricating grease inside the oil storage cavity into the oil outlet cavity.

[0012] Preferably, each group of the oil outlet holes is provided with three, and the three oil outlet holes are arranged in a circumferential arrangement on the inner side of the outer wall of the oil storage cavity. The angle between the three oil outlet holes is 120 degrees.

[0013] Preferably, the oil outlet is arranged in an inverted "V" shape with a narrow inner part and a wide outer part. A first movable baffle and a second movable baffle are movably installed inside the oil outlet. The first movable baffle and the second movable baffle are arranged oppositely, and the opposite positions of the first movable baffle and the second movable baffle are meshed in an inclined tooth shape.

[0014] Preferably, two chutes are respectively opened on both sides of the oil outlet, and sliders adapted to the chutes are respectively arranged on one sides of the first movable baffle and the second movable baffle close to the inner wall of the oil outlet. Two fixing blocks are respectively fixedly installed on one side of the oil outlet close to the oil storage cavity. A return spring is arranged between each of the two fixing blocks and the first movable baffle and the second movable baffle respectively. A sealing gasket is arranged at the opposite meshing position of the first movable baffle and the second movable baffle, and the sealing gasket is made of rubber.

[0015] Preferably, the cable bolt body is integrally cast with 316L stainless steel material, and the outer surface of the cable bolt body is processed by manual mirror finishing.

[0016] This application also discloses an adjustable locking method for a marine slide rail cable bolt. Using the above-mentioned adjustable marine slide rail cable bolt, it includes the following steps:

[0017] S1: Install a slide rail on the ship's side. The slide rail can be customized according to the curvature and length of the ship's side to ensure proper installation and use;

[0018] S2: When the cable bolt body needs to be moved, the operator hooks the positioning handle, causing the handle to drive the rotating shaft to rotate. The rotating shaft drives the sliding positioning pin to retract through the positioning block and the linkage rod, thereby unlocking the cable bolt body;

[0019] S3: After unlocking, the operator slides the cable bolt body along the slide rail to the required position to ensure adjustment to the appropriate positioning point;

[0020] S4: Release the positioning handle, and the sliding positioning pin automatically resets under the action of the linkage rod, firmly fixing the cable bolt body at the new position on the slide rail;

[0021] S5: Confirm that the cable bolt is firmly locked on the slide rail to ensure that the equipment will not shift during use, and the operation is completed.

[0022] The beneficial effects of the present invention:

[0023] 1. The adjustable marine slide rail cable stopper and its locking method are provided with a locking component. Through the cooperation of the positioning handle with the rotating shaft, positioning block, and linkage rod, the operator can easily lift the handle to unlock and move the cable stopper. The operation is simple and convenient, greatly improving the flexibility of use. After unlocking, the sliding positioning pin can quickly reset and firmly lock the cable stopper to ensure its stable position on the slide rail without displacement, guaranteeing the safe use of the equipment in harsh environments. The hollow design of the positioning handle not only reduces the weight of the handle and the fatigue of operation but also enhances the smoothness of operation. There is a gap at the bottom of the handle, making the operation more comfortable.

[0024] 2. The adjustable marine slide rail cable stopper and its locking method are provided with a lubrication component. Through the combination of the oil storage cavity and the oil outlet cavity, the lubricating grease can be automatically distributed and evenly discharged through the oil outlet without additional operation, achieving continuous and precise lubrication. Each group of oil outlets is designed in an "eight" shape. As the cable stopper body slides rapidly on the slide rail, inertia causes the first movable baffle and the second movable baffle to gradually open the oil outlet to ensure the effective discharge of grease during the operation of the equipment. When the sliding stops, the return spring closes the oil outlet in a timely manner to prevent excessive grease from being discharged, ensuring the stability and efficiency of the lubrication effect. At the same time, the rubber gasket is provided to ensure good sealing at the oil outlet in the non-working state, preventing grease leakage and guaranteeing the long-term reliability of the lubrication device. In addition, the hollow structure of the fixed column and the oil injection hole design facilitate the replenishment of lubricating oil, ensuring that there is always sufficient grease reserve in the system during long-term use, greatly reducing the maintenance frequency and extending the service life of the equipment.

Detailed implementation manners

[0037] To make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with specific embodiments.

[0038] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the present invention should have the ordinary meanings understood by those with ordinary skills in the field to which the present invention belongs. The "first", "second" and similar terms used in the present invention do not indicate any order, quantity or importance, but are only used to distinguish different components.

The terms such as "connected" or "coupled" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. The terms such as "upper", "lower", "left" and "right" are only used to indicate relative positional relationships, and when the absolute position of the object being described changes, the relative positional relationship may also change accordingly.

[0039] Such as Figures 1 to 9As shown, the adjustable marine slide rail shackle includes a shackle body 1. The shackle body 1 is arranged in an H shape. At the bottom end of the shackle body 1, there is a ship's side fixed slide rail 2. Above the ship's side fixed slide rail 2, several shackle positioning holes 3 are opened. Above the ship's side fixed slide rail 2, several slide rail fixing bolts 4 are also provided. The shackle positioning holes 3 and the slide rail fixing bolts 4 are arranged alternately. On one side inside the shackle body 1, several sliding positioning pins 5 are movably installed; a locking component, which is arranged on one side of the top surface of the shackle body 1 and is used to control several sliding positioning pins 5 to lock the shackle body 1 with an external slide rail; a lubricating component, which is arranged on the other side of the shackle body 1 and is used to self-lubricate the connection between the ship's side fixed slide rail 2 and the external slide rail. Among them, the shackle body 1 is integrally cast with 316L stainless steel material, and the outer surface of the shackle body 1 is processed by manual mirror finishing;

[0040] When it is necessary to adjust the position of the shackle, the operator controls the sliding positioning pin 5 to release the locked state through the locking component, allowing the shackle body 1 to slide freely on the slide rail. When the shackle body 1 moves to the appropriate position, the operator uses the locking component again to fix the sliding positioning pin 5 to the slide rail to ensure that the shackle is stably locked in the specified position. During this process, the lubricating component continuously self-lubricates the connection between the ship's side fixed slide rail 2 and the external slide rail, ensuring a smooth sliding process and reducing wear. Among them, the shackle body 1 is integrally formed with 316L stainless steel material, with high strength and corrosion resistance characteristics, which is very suitable for use in the ship environment, especially in the seawater environment. Its rust resistance ability is remarkable, ensuring the long service life of the shackle. The manual mirror finishing on the outer surface not only improves the corrosion resistance but also enhances the aesthetics, reduces friction and the adhesion of dirt. And the sliding positioning pin 5 is controlled by the locking component to achieve a firm connection between the shackle body 1 and the external slide rail, thus ensuring the stability of the shackle during use. The lubricating component can automatically lubricate between the ship's side fixed slide rail 2 and the external slide rail, reduce friction, extend the service life, and at the same time reduce the frequency of manual maintenance.

[0041] As Figures 1 to 5 As shown, the locking component includes a positioning plate 6 arranged on one side of the top surface of the shackle body 1. The positioning plate 6 is arranged in a sunken manner. A rotating shaft 8 is rotatably installed through one side of the positioning plate 6. The rotating shaft 8 is fixedly connected with a positioning handle 7. The positioning handle 7 is rotatably installed inside the positioning plate 6. On both sides of the rotating shaft 8, positioning blocks 9 are fixedly connected. At the bottom of the two positioning blocks 9, a connecting rod 10 is fixedly connected. The top of the sliding positioning pin 5 is rotatably connected with the top of several connecting rods 10. One side of the positioning handle 7 is provided with a hollow. There is a gap between the bottom of the hollow side of the positioning handle 7 and the bottom surface of the positioning plate 6;

[0042] First, install sliding tracks on the ship's side according to actual requirements. The sliding tracks can be customized to adapt to the curvature and length of the ship's side. During use, the operator only needs to easily lift the positioning handle 7, driving the rotating shaft 8 to rotate. The rotating shaft 8 drives the sliding positioning pin 5 to retract through the positioning block 9 and the linkage rod 10, thus unlocking the cable bolt. After unlocking, the operator slides the cable bolt body 1 to the desired position. After releasing the finger, the sliding positioning pin 5 resets, firmly locking the cable bolt in the new position on the sliding track. The whole operation is fast and simple, with stable and firm positioning. The positioning handle 7 is designed with a hollow structure, reducing the weight of the handle. And there is a gap between the bottom of the handle and the positioning plate 6, making the handle operation smoother and more convenient. After releasing the positioning handle 7, the sliding positioning pin 5 quickly resets under the action of the linkage rod 10, firmly locking the cable bolt body 1 on the slide rail to ensure that the equipment remains stable and does not shift during use.

[0043] As Figure 2 , Figure 3 , Figure 6 , Figure 7 shown, the lubrication assembly includes a slide rail lubricating grease chamber 11 fixedly installed inside the other side of the cable bolt body 1. A positioning cylinder 12 is fixedly installed inside the slide rail lubricating grease chamber 11. An oil outlet cavity 21 is arranged between the slide rail lubricating grease chamber 11 and the positioning cylinder 12. A number of lubrication ports 22 are opened above the oil outlet cavity 21. The lubrication ports 22 are used to discharge lubricating liquid or lubricating grease. A fixing column 14 is axially installed in the middle of the inner side of the positioning cylinder 12. An oil storage cavity 13 is arranged between the outer wall of the fixing column 14 and the inner wall of the positioning cylinder 12. The fixing column 14 is hollow. An oil injection hole 15 is arranged on one side of the inner wall of the fixing column 14. The oil injection hole 15 is used to supplement and inject lubricating grease. A number of groups of oil outlet openings 16 are opened on the side wall of the positioning cylinder 12. The number of groups of oil outlet openings 16 is used to discharge the lubricating grease inside the oil storage cavity 13 into the oil outlet cavity 21;

[0044] When the equipment needs lubrication, the lubricating grease in the oil storage cavity 13 automatically flows into the oil outlet cavity 21 through a number of oil outlet openings 16 on the side wall of the fixing column 14. The lubricating grease in the oil outlet cavity 21 is evenly discharged through the lubrication ports 22 to lubricate the connection part between the cable bolt body 1 and the external sliding track. During use, the hollow structure of the fixing column 14 can supplement lubricating grease at any time through the oil injection hole 15 to ensure that there is always enough reserve in the lubricating grease chamber. The system maintains the continuity of the lubrication effect while automatically distributing the grease, avoiding equipment wear and ensuring smooth operation.

[0045] As Figures 6 to 9As shown, each group of oil outlets 16 is provided with three, and the three oil outlets 16 are arranged in a circular pattern on the inner side of the outer wall of the oil storage cavity 13. The angle between the three oil outlets 16 is 120 degrees. The oil outlets 16 are arranged in a "V" shape with a narrow inner side and a wide outer side. A first movable baffle 18 and a second movable baffle 19 are movably installed inside the oil outlets 16. The first movable baffle 18 and the second movable baffle 19 are arranged oppositely, and the opposite positions of the first movable baffle 18 and the second movable baffle 19 are engaged in an oblique tooth shape. Two chutes are respectively opened on both sides of the oil outlet 16, and sliders adapted to the chutes are respectively arranged on the sides of the first movable baffle 18 and the second movable baffle 19 close to the inner wall of the oil outlet 16. Two fixing blocks 17 are respectively fixedly installed on the side of the oil outlet 16 close to the oil storage cavity 13. A return spring 23 is arranged between the two fixing blocks 17 and the first movable baffle 18 and the second movable baffle 19 respectively. A sealing gasket 20 is arranged at the opposite engagement position of the first movable baffle 18 and the second movable baffle 19. The sealing gasket 20 is made of rubber material;

[0046] During the lubrication process, it is necessary to release the fixation of the limit pin, and then quickly slide the bolt body 1 on the slide rail. When the bolt body 1 quickly slides on the slide rail, the inertial effect causes the first movable baffle 18 and the second movable baffle 19 of the oil outlet 16 to slide in the chute. The two baffles gradually open the "V"-shaped oil outlet 16 during the sliding process, and the lubricating grease is discharged through the oil outlet 16 to provide lubrication between the bolt body 1 and the slide rail. When the sliding stops, the return spring 23 pushes the two movable baffles back to their original positions, and the oil outlet 16 closes to prevent the grease from continuing to be discharged. The whole process does not require additional operations. The lubrication process is automatically completed according to the sliding of the bolt and automatically resets when it stops, ensuring the accuracy and efficiency of lubrication. The rubber material sealing gasket 20 arranged at the oil outlet 16 ensures good sealing of the oil outlet 16 in the non-use state, prevents the leakage of lubricating grease, and at the same time ensures the long-term use performance of the lubrication device and extends the service life of the equipment.

[0047] The present invention also discloses an adjustable locking method for a marine slide rail bolt, using the above-mentioned adjustable marine slide rail bolt, including the following steps:

[0048] S1: Install a slide rail on the ship's side. The slide rail can be customized according to the curvature and length of the ship's side to ensure proper installation and use;

[0049] S2: When it is necessary to move the bolt body 1, the operator hooks the positioning handle 7 to drive the rotating shaft 8 to rotate. The rotating shaft 8 drives the sliding positioning pin 5 to retract through the positioning block 9 and the linkage rod 10, thereby unlocking the bolt body 1;

[0050] S3: After unlocking, the operator slides the bolt body 1 along the slide rail to the required position to ensure adjustment to the appropriate positioning point;

[0051] S4: Release the positioning handle 7. The sliding positioning pin 5 automatically resets under the action of the linkage rod 10, and firmly fixes the cable bolt body 1 at a new position on the sliding track.

[0052] S5: Confirm that the cable bolt is firmly locked on the sliding track to ensure that the device will not shift during use, and the operation is completed.

[0053] Compared with the prior art, the user can unlock and slide the cable bolt by simply hooking up the positioning handle 7. After adjusting to the appropriate position, release the handle, and the sliding positioning pin 5 automatically resets and is firmly locked, without the need for additional tools or complex operations, greatly improving the usability. Secondly, the sliding track can be customized according to the curvature and length of the ship's side, flexibly adapting to different ship structures and meeting the requirements of various scenarios. This method can also ensure that the cable bolt body 1 does not shift stably during use.
