Description

Technical Field

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

[0002] A cable is a rope or chain used on ships to perform operations such as mooring, anchoring, hoisting, and towing. To ensure the strength of the cable, it is usually made of high-strength materials such as steel wire, nylon, and polyester fiber. Different types and specifications of cables can be selected according to different uses and working environments.

[0003] In existing technologies, various methods are typically employed to address issues such as cable wear, detachment, or jamming that may occur during cable guiding. For example, a common method is to install a cable guide wheel with ball bearings on a fixed base to reduce cable wear by minimizing friction; another method is to use a rigid protective cover to protect the cable guide wheel from interference from external objects; yet another method is to manually adjust the position of the cable guide wheel to accommodate cables of different diameters.

[0004] However, the aforementioned existing technologies generally have certain drawbacks. In particular, when the cable tension is high or the operating space is limited, the position of the guide wheel is inconvenient to adjust and there is a lack of effective protective measures, which can easily lead to cable slippage or damage. Utility Model Content

[0005] To further reduce the possibility of cable slippage or damage, this application provides a ship cable guide device.

[0006] The technical solution for a ship cable guide device provided in this application is as follows:

[0007] A ship guide cable device includes a fixed base, with support blocks installed on both sides of the fixed base. A guide cable wheel is rotatably connected to the inner wall of the support block. The support block is slidably installed along the length of the fixed base. A telescopic guard rod is installed on the upper end of the inner wall of the support block. One end of the telescopic guard rod is hinged to the support block, and the other end is fitted with a snap-fit ​​for connecting the two telescopic guard rods.

[0008] By adopting the above technical solution, support blocks are installed on both sides of the fixed base, and guide wheels are rotatably connected to the inner sidewalls of the support blocks, enabling the cable to be guided and slide smoothly, effectively reducing cable wear. The support blocks are slidably installed along the length of the fixed base, and the position of the guide wheels can be adjusted according to actual needs, improving the flexibility and adaptability of the device. One end of the telescopic protective rod is hinged to the support block, and the other end is connected via a snap-fit, forming an adjustable protective structure. This provides additional protection when the cable is under abnormal stress, preventing the cable from coming off or being damaged, while also facilitating operation and maintenance.

[0009] In one specific implementation, a sliding groove is provided on the fixed base, and a driving component is provided in the sliding groove. The driving component is used to drive the two support blocks to slide synchronously in opposite directions. The driving component includes a drive motor and a drive screw. The drive motor is mounted on the fixed base, and the drive screw is mounted in the sliding groove. The support blocks are slidably connected in the sliding groove and driven by the drive screw. The drive screw has threaded grooves with opposite patterns on its outer surface from the middle to both ends.

[0010] By adopting the above technical solution, the cooperation between the drive motor and the drive screw enables the synchronous reverse sliding of the two support blocks, thereby adjusting the distance between the cable guide wheels to accommodate cables of different diameters. The reverse-groove thread design allows the drive screw to simultaneously push the two support blocks in opposite directions when rotating, simplifying the structure and improving operational efficiency.

[0011] In one specific implementation, ball bearings are installed at both ends and the middle part of the drive screw, and the ball bearings are correspondingly installed at both ends and the middle part of the slide groove.

[0012] By adopting the above technical solution, the installation of ball bearings can effectively reduce the rotational friction of the drive screw within the groove, improve transmission efficiency, and enhance the operational stability of the drive screw. The ball bearings are respectively installed at both ends and the middle of the drive screw, ensuring uniform force distribution and preventing deformation or damage caused by uneven local force, thereby extending the service life of the device.

[0013] In one specific implementation scheme, the telescopic protective rod includes a sleeve and a sliding rod. One end of the sleeve is hinged to the support block. A sliding groove is provided inside the sleeve and is arranged along the length of the sleeve. The sliding groove passes through the sleeve and is located at the end opposite to the support block. The sliding rod is slidably connected in the sliding groove and has one end extending out of the sliding groove. A snap-fit ​​is installed at the end of the sliding rod that extends out of the sliding groove.

[0014] By adopting the above technical solution, the telescopic safety bar consists of a sleeve and a sliding rod. One end of the sleeve is hinged to a support block, and a groove is opened inside to achieve a sliding connection of the sliding rod. The sliding rod can extend or retract within the groove, and a snap-fit ​​component is installed at the extended end of the sliding rod. This design allows the telescopic safety bar to be adjusted in length according to actual needs, thus providing flexible protection during ship cable guiding, effectively preventing the cable from jumping or slipping off the guide sheave. At the same time, the hinged structure allows the telescopic safety bar to adapt to different angles of cable stress, improving the applicability and safety of the device.

[0015] In one specific implementation, a telescopic spring is also included. The telescopic spring is installed inside the slide groove and at the end of the slide rod that does not extend out of the slide groove. One end of the telescopic spring is fixedly connected to the inner sidewall of the slide groove, and the other end is fixedly connected to the slide rod.

[0016] By adopting the above technical solution, the telescopic spring effectively prevents the slide bar from accidentally detaching from the groove, thus improving the structural stability of the telescopic protective rod. In actual use, when the slide bar is subjected to external force, the telescopic spring provides a counterforce, thereby preventing excessive sliding or detachment of the slide bar and ensuring that the telescopic protective rod always maintains a reliable connection.

[0017] In one specific implementation, the latching component includes a first latching seat, a second latching seat, a first latching claw, a second latching claw, a first limiting block, and a second limiting block. A mounting groove is provided on a sliding rod, the first latching seat is installed in the mounting groove, the first latching claw is installed on the end of the first latching seat opposite to the sliding rod, and the first limiting block is connected to the first latching claw. The second latching seat is installed on another sliding rod, the second latching claw is installed on the second latching seat, and the second limiting block is connected to the second latching claw. As the second latching seat rotates, the first latching claw engages with the second limiting block, and the second latching claw engages with the first limiting block.

[0018] By adopting the above technical solution, the structural design of the locking component achieves a reliable connection between the two telescopic guard rods. Specifically, the first and second locking seats are respectively installed on the two sliding rods, and the first and second locking claws respectively cooperate with the first and second limiting blocks. Through the rotation of the second locking seat, the first locking claw can engage with the second limiting block, while the second locking claw engages with the first limiting block, thereby achieving quick locking and unlocking of the two telescopic guard rods. This design not only improves the safety of the ship's guide cable device but also enhances its operational flexibility.

[0019] In one specific implementation scheme, the first claw, the first limiting block, the second claw, and the second limiting block are all provided in two sets. The two sets of first claws and first limiting blocks are symmetrically installed on the first card seat, and the two sets of second claws and second limiting blocks are symmetrically installed on the second card seat.

[0020] By adopting the above technical solution, the first claw, the first limiting block, the second claw, and the second limiting block are all configured in two sets and symmetrically installed on their corresponding mounting bases, which significantly improves the connection stability of the locking components. The symmetrical arrangement ensures more even force distribution, avoiding connection failures caused by unilateral force, thereby enhancing the reliability of the connection between telescopic guardrails. Simultaneously, this design also improves the overall structural strength of the device, ensuring the normal operation of the cable guide device under complex working conditions.

[0021] In one specific implementation scheme, a rotating groove is provided on the slide rod on which the second card holder is installed, and a rotating block is provided on the second card holder. The rotating block is rotatably connected in the rotating groove. A limiting groove is provided on the side wall of the rotating groove. A push rod is installed on the rotating block. The push rod extends out of the limiting groove and can slide in the limiting groove. A limiting spring is provided on the side wall of the limiting groove. One end of the limiting spring is connected to the side wall of the limiting groove, and the other end is connected to the push rod. It is used to limit the position of the push rod to ensure that the first claw is engaged with the first limiting block and the second claw is engaged with the second limiting block.

[0022] By adopting the above technical solution, the rotating groove allows the second card holder to rotate relative to the slide rod, thereby enabling flexible adjustment of the locking components to meet different connection requirements. The cooperation between the rotating block and the rotating groove further improves the stability of rotation. The design of the push rod and the limiting groove allows users to manually adjust the angle of the second card holder, and the elasticity of the limiting spring fixes the position of the push rod, ensuring reliable locking between the first claw and the first limiting block, and between the second claw and the second limiting block, effectively preventing loosening of the connection and improving the stability and safety of the overall device.

[0023] In one specific implementation scheme, the thickness of both the first limiting block and the second limiting block is set from thin to thick, and is set to correspond to the rotation direction of the second card holder.

[0024] By adopting the above technical solution, the thickness of the first limiting block and the second limiting block is set from thin to thick, and corresponding to the rotation direction of the second card seat, so that the first and second card claws can gradually contact the limiting blocks and complete a stable connection during the clamping process, effectively improving the reliability and stability of the clamping, while reducing the impact force during clamping and extending the service life of the components.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. By setting sliding support blocks and driving components on both sides of the fixed base, the position of the cable guide wheel can be flexibly adjusted to adapt to cables of different diameters and tensions, thereby improving the operational flexibility and applicability of the cable guide device;

[0027] 2. The telescopic guard bar is designed to expand or retract according to actual needs, providing reliable protection for the cable guide wheel, effectively preventing interference from external foreign objects and cable slippage, and improving the safety of the cable guide device;

[0028] 3. The ingenious design of the snap-fit ​​connector makes the connection between the two telescopic guard rods more stable and easier to operate, further enhancing the reliability and convenience of the protective function. Attached Figure Description

[0034] This application discloses a ship cable guide device.

[0035] like Figure 1 and Figure 2 As shown, the ship's guide cable device includes a fixed base 1, a support block 2, a guide wheel 3, a telescopic guard rod, and a snap-fit ​​connector 7. The support block 2 is slidably installed along the length of the fixed base 1. One end of the telescopic guard rod is hinged to the support block 2, and the other end is connected between the two telescopic guard rods via the snap-fit ​​connector 7, thereby improving the flexibility of the guide wheel's position adjustment and enhancing the protective effect.

[0036] like Figure 3 As shown, in this embodiment of the application, a driving component 5 is also included. The driving component 5 includes a driving motor 51 and a driving screw 52. The driving motor 51 is mounted on a fixed base 1. A sliding groove is provided on the fixed base 1. The driving screw 52 is installed in the sliding groove. The support block 2 is slidably connected in the sliding groove and is drivenly connected to the driving screw 52. The driving screw 52 has a threaded groove with opposite textures on its outer surface from the middle to both ends.

[0037] Specifically, the drive motor 51 can be a stepper motor or a servo motor. Stepper motors have high positioning accuracy and are suitable for applications requiring precise control; servo motors have high dynamic response speed and are suitable for applications requiring rapid adjustment. The drive screw 52 can use trapezoidal threads or ball threads. Trapezoidal threads have strong self-locking ability and are suitable for applications requiring high stability; ball threads have a low coefficient of friction and high transmission efficiency and are suitable for applications requiring frequent adjustment. Ball bearings 6 are installed at both ends and the middle of the drive screw 52, ​​corresponding to the ends and the middle of the slide groove, thereby ensuring the stable operation of the drive screw 52.

[0038] The telescopic guardrail includes a sleeve 41 and a sliding rod 42. The sleeve 41 is made of stainless steel, while the sliding rod 42 can be made of aluminum alloy. One end of the sleeve 41 is hinged to the support block 2 via a hinge. The hinge can be a ball joint or a pin joint. The ball joint has multi-degree-of-freedom movement capability and is suitable for complex environments; the pin joint has a simple structure and is suitable for general environments. A groove is formed inside the sleeve 41, extending through the sleeve 41 and located at the end opposite to the support block 2. The sliding rod 42 is slidably connected within the groove, with one end extending out of the groove. A snap-fit ​​component 7 is installed at the end of the sliding rod 42 extending out of the groove. The sliding rod 42 can slide within the groove, thereby realizing the telescopic function of the guardrail.

[0039] In this embodiment, a telescopic spring 43 is also included. The telescopic spring 43 is installed in the slide groove, with one end fixedly connected to the inner sidewall of the slide groove and the other end fixedly connected to the slide rod 42. The telescopic spring 43 can be a compression spring or a tension spring. For example, a compression spring has a larger elastic deformation capacity and is suitable for applications requiring a larger buffering force; a tension spring has a smaller elastic deformation capacity and is suitable for applications requiring a smaller buffering force. The function of the limiting spring 79 is to limit the sliding range of the slide rod 42 in the slide groove, preventing the slide rod 42 from sliding excessively and causing the telescopic protective rod to fail.

[0040] like Figure 4As shown, the latching component 7 includes a first latching seat 71, a second latching seat 72, a first latching claw 73, a second latching claw 74, a first limiting block 75, and a second limiting block 76. The first latching seat 71 is installed in the mounting groove of one of the slide rods 42, the first latching claw 73 is installed at the end of the first latching seat 71 opposite to the slide rod 42, and the first limiting block 75 is connected to the first latching claw 73. The second latching seat 72 is installed on the other slide rod 42, the second latching claw 74 is installed on the second latching seat 72, and the second limiting block 76 is connected to the second latching claw 74. As the second latching seat 72 rotates, the first latching claw 73 engages with the second limiting block 76, and the second latching claw 74 engages with the first limiting block 75. The first latching seat 71 and the second latching seat 72 can be made of aluminum alloy, the first latching claw 73 and the second latching claw 74 can be made of high-strength steel, and the first limiting block 75 and the second limiting block 76 can be made of wear-resistant engineering plastic. The first claw 73 and the second claw 74 can be designed in the shape of hooks to facilitate locking; the thickness of the first limiting block 75 and the second limiting block 76 can be set from thin to thick and corresponding to the rotation direction of the second card holder 72, thereby ensuring the reliability of locking.

[0041] Specifically, a rotating groove is provided on the slide rod 42 of the second mounting bracket 72, and a rotating block 77 is provided on the second mounting bracket 72, which is rotatably connected within the rotating groove. A limiting groove is provided on the side wall of the rotating groove, and a push rod 78 is installed on the rotating block 77. The push rod 78 extends out of the limiting groove and can slide within it. A limiting spring 79 is provided on the side wall of the limiting groove. One end of the limiting spring 79 is connected to the side wall of the limiting groove, and the other end is connected to the push rod 78. This spring is used to limit the position of the push rod 78, ensuring that the first claw 73 engages with the first limiting block 75, and the second claw 74 engages with the second limiting block 76. The limiting spring 79 can be a compression spring, and the push rod 78 can be made of stainless steel. For example, the shape of the limiting groove can be designed as an arc to facilitate the sliding of the push rod 78; the preload of the limiting spring 79 can be adjusted according to actual needs to ensure the reliability of the engagement.

[0042] The implementation principle of a ship guide cable device according to an embodiment of this application is as follows: The sliding support block 2 allows for flexible adjustment of the guide cable wheel position, accommodating cables of different diameters; the telescopic protective rod and the locking component 7 work together to effectively protect the guide cable wheel, preventing interference from external foreign objects and cable slippage. This design not only improves the operational flexibility and safety of the guide cable device but also enhances its durability and reliability, providing reliable protection for ship mooring, anchoring, hoisting, and towing operations.

[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
