Description

Technical Field

[0001] This application relates to the technical field of marine equipment, and in particular to a marine towing device. Background Technology

[0002] In the field of ship operations, ship towing is an extremely common and important task. Currently, traditional face-towing piles have revealed many problems during ship towing. Among them, the most prominent is that face-towing piles cannot effectively adjust the height of the rigging rope according to the actual length of the towing pile.

[0003] Different towing scenarios, such as operations in shallow and deep water, present vastly different environmental factors including currents and depths. Furthermore, the optimal towing point height varies among different types of vessels due to differences in their design purpose and hull structure. Existing towing devices, lacking the flexibility to adjust the towing point height, fail to effectively reduce towing resistance during actual towing operations. For example, when towing small fishing boats, an excessively high towing point causes the bow to rise excessively, increasing drag and reducing towing efficiency; conversely, when towing large cargo ships, a towing point that is too low may cause the stern to sink, affecting maneuverability and similarly reducing towing efficiency.

[0004] In summary, existing ship towing devices, when faced with complex and diverse towing scenarios and ship types, cannot flexibly adjust the towing point height due to the lack of adjustable rope height by the face towing pile. Consequently, it is difficult to reduce towing resistance and improve towing efficiency. There is an urgent need for a new type of ship towing device to solve these problems. Utility Model Content

[0005] In order to reduce towing resistance and improve towing efficiency, this application provides a ship towing device.

[0006] The ship towing device provided in this application adopts the following technical solution:

[0007] A ship towing device includes a hydraulic winch mounted on a ship's hull. A main pile is located on one side of the hydraulic winch and is fixed to the hull. Branch piles are located on both sides of the main pile. An adjusting assembly is provided between the branch piles and the hull for connecting the two. An adjusting sleeve is slidably connected to each branch pile. A fixing assembly is provided on the adjusting sleeve for fixing the adjusting sleeve to the branch pile. A groove is formed on the outer wall of the adjusting sleeve, and the groove is arranged along the axis of the adjusting sleeve. A towing cable is wound around the hydraulic winch, and a towing hook is installed at the end of the towing cable. The towing cable is also wound within the groove.

[0008] By adopting the above technical solutions, the ship towing device can effectively fix and adjust the towline. A hydraulic winch provides power output, allowing the towline to be flexibly deployed and retracted to meet different towing needs. The main pile and branch piles enhance the stability of the device, preventing displacement or capsizing during towing. The adjustment assembly allows the branch piles to be positioned relative to the hull, adapting to different towing angles and environmental conditions. Simultaneously, the groove design provides a stable winding path for the towline, preventing slippage or detachment during use, improving the safety and reliability of the towing process. The sliding connection between the adjusting sleeve and the branch pile, combined with the fixing assembly, allows the winding point of the towline to be precisely adjusted according to actual needs, achieving the optimal labor-saving height. The fixing assembly securely fixes the adjusting sleeve to the branch pile, reducing displacement of the towline under stress, thereby reducing towing resistance and improving towing efficiency.

[0009] Optionally, the bottom of the groove is provided with a rubber sleeve, which surrounds the bottom wall of the groove.

[0010] By adopting the above technical solution, the rubber sleeve is set around the bottom wall of the groove, which further enhances the wrapping and protection effect of the towing cable, while increasing the friction force generated by the direct contact between the towing cable and the bottom of the groove.

[0011] Optionally, the fixing component includes a fixing block, on which a fixing bolt is threadedly connected, and the sub-pile has a plurality of first threaded holes arranged along the length direction of the sub-pile, and the fixing bolt is threadedly connected in the first threaded holes.

[0012] By adopting the above technical solution, the fixing bolts can be connected to different first threaded holes as needed, thereby adjusting the position of the fixing block on the sub-pile. This design makes the fixing position of the adjusting sleeve on the sub-pile more flexible, meeting the needs of different working conditions, while ensuring the stability of the connection.

[0013] Optionally, a limiting block is fixedly connected to the inner wall of the adjusting sleeve, a limiting groove is opened on the branch pile, the limiting groove is set along the length direction of the branch pile, and the limiting block is slidably connected in the limiting groove.

[0014] By adopting the above technical solutions, the stability and reliability of the device are improved. Meanwhile, the design of the limiting block and limiting groove simplifies the installation and fixing process of the adjusting sleeve, making it easier for operators to adjust and maintain.

[0015] Optionally, the adjusting component is fixedly connected to a guide block on the hull, the guide block has a guide groove, an adjusting block is slidably connected in the guide groove, the adjusting block is provided with a positioning component for fixing the adjusting block in the guide groove, and the branch pile is fixedly connected to the guide block.

[0016] By adopting the above technical solution, and by setting guide blocks on the hull and creating guide grooves on the guide blocks, the adjusting blocks can slide within the guide grooves, thereby achieving flexible adjustment of the pile positions and improving the adaptability of the device. Furthermore, the positioning component can fix the adjusting blocks in specific positions within the guide grooves, ensuring the stability of the piles during operation and preventing positional deviations caused by external factors.

[0017] Optionally, the positioning component includes a threaded rod, and multiple second threaded holes are provided on both sides of the guide block along the length direction of the guide block. The threaded rod is located on both sides of the guide block, and the threaded rod passes through the second threaded holes and is threadedly connected to the guide block.

[0018] By adopting the above technical solution, the cooperation between the threaded rod and the second threaded hole enhances the stability of the positioning component, prevents the piles from loosening during operation, and thus ensures the overall performance stability of the towing device.

[0019] Optionally, a hydraulic cylinder is provided on one side of the guide block, the hydraulic cylinder is fixed to the hull, and the piston rod of the hydraulic cylinder is fixedly connected to the adjusting block.

[0020] By adopting the above technical solution, the connecting chain between the branch piles and the main pile can maintain the stability of the overall structure during adjustment, preventing the branch piles from shifting or falling off, and ensuring the reliability of the towing device in complex sea conditions. The introduction of hydraulic cylinders significantly enhances the automation and adaptability of the device, providing a more flexible operating method for ship towing operations.

[0021] Optionally, a connecting chain is provided between the branch pile and the main pile to fix the two together.

[0022] By adopting the above technical solution, the stability of the overall structure can be enhanced, and relative displacement between the sub-piles and the main pile can be prevented during the towing process, thereby improving the working reliability of the towing device.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The sliding connection between the adjusting sleeve and the branch pile, along with the fixing component, allows the winding point of the towing cable to be precisely adjusted according to actual needs to achieve the optimal labor-saving height. The fixing component also securely fixes the adjusting sleeve to the branch pile, reducing the displacement of the towing cable under stress, thereby reducing towing resistance and improving towing efficiency.

[0025] 2. This allows the adjusting block to slide within the guide groove, enabling flexible adjustment of the pile position and improving the adaptability of the device. Furthermore, the positioning component can fix the adjusting block in a specific position within the guide groove, ensuring the pile remains stable during operation and preventing positional deviations caused by external factors.

[0026] 3. The use of the threaded rod and the second threaded hole enhances the stability of the positioning component and prevents the piles from loosening during operation, thereby ensuring the overall stability of the towing device. Attached Figure Description

[0030] The following is in conjunction with the appendix Figure 1 -Appendix Figure 2 This application will be described in further detail below.

[0031] An embodiment of this application is: a ship towing device, referring to... Figure 1 and Figure 2 The system includes a hydraulic winch 2 installed on the hull, which is the hydraulic winch 2 on the hull in the prior art. A main pile 1 is provided on one side of the hydraulic winch 2, and the main pile 1 is fixed to the hull and integrally formed with the hull.

Thus, the position of the adjusting block 42 within the guide groove 411 can be adjusted by controlling the extension and retraction of the hydraulic cylinder 12. After adjustment, the threaded rod 131 is rotated, causing it to be threaded into the adjusting block 42, thereby quickly fixing the adjusting block 42 and thus fixing the position of the column.

[0035] An adjusting sleeve 5 is slidably connected to the branch pile 3. A limiting block 10 is fixedly connected to the inner wall of the adjusting sleeve 5. A limiting groove 32 is opened on the branch pile 3, and the limiting groove 32 is set along the length direction of the branch pile 3.

[0036] The fixing component 6 includes a fixing block 61, on which a fixing bolt 62 is threadedly connected. Multiple first threaded holes 31 are opened on the branch pile 3. The multiple first threaded holes 31 are equidistantly arranged along the length direction of the branch pile 3. The fixing bolt 62 is threadedly connected in the first threaded hole 31, thereby the adjusting sleeve 5 is fixed on the branch pile by the fixing bolt 62.

[0037] A groove 51 is formed on the outer wall of the adjusting sleeve 5, and the groove 51 is arranged along the axis of the adjusting sleeve 5. A tow cable 7 is wound on the hydraulic winch 2, and a tow hook 8 is installed at the end of the tow cable 7. The tow cable 7 is also wound inside the groove 51. At the same time, in order to increase the friction generated by the contact between the tow cable 7 and the bottom of the groove 51, a rubber sleeve 9 is provided at the bottom of the groove 51. The rubber sleeve 9 is arranged around the bottom wall of the groove 51, and the tow cable 7 is wound on the rubber sleeve 9. Thus, the height of the adjusting sleeve 5 can be changed by sliding the adjusting sleeve 5 according to the height of the hull, thereby changing the height of the tow cable 7, and thus adapting to different hull heights.
