Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable repair boat technology, specifically to a side cable lifting mechanism for a cable repair boat. Background Technology
[0002] In offshore cable repair operations, the cable lifting mechanism on the side of the cable repair boat plays a crucial role. Traditional cable lifting mechanisms are usually fixedly installed on the side of the ship, with a relatively simple structure that makes it difficult to flexibly adjust their position and height. Due to the lack of an effective lateral telescopic adjustment structure, when the repair boat is repairing cables while in motion, the cables are very likely to rub against the hull. This can not only cause damage to the cable surface, affecting its insulation performance and transmission function, but may also lead to serious faults such as short circuits due to localized damage, reducing the cable's service life and reliability.
[0003] Meanwhile, traditional cable lifting mechanisms rely solely on a single lifting structure with limited lifting range. When cables need to be raised from deeper waters to the repair boat, they often cannot reach sufficient depth, making it difficult for workers to easily bring the underwater cables to the surface for repairs, increasing the difficulty and time cost of maintenance. Furthermore, this single lifting structure lacks an effective transmission mechanism, resulting in slow lifting speeds that cannot meet the demands of rapid repair operations. In emergency repair scenarios, it is difficult to quickly address faulty cables, potentially delaying repairs and causing wider power or communication outages. Based on these drawbacks of traditional cable lifting mechanisms, there is an urgent need to develop a new type of side-mounted cable lifting mechanism for cable repair boats to solve many of the problems in existing technologies and improve the efficiency and safety of cable repair operations. Utility Model Content
[0004] The purpose of this utility model is to overcome the defects existing in the prior art and provide a side cable lifting mechanism for a cable repair boat.
[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A side cable lifting mechanism for a cable repair boat includes a mounting base, a lateral telescopic slide section, a lifting slide section, and a lifting platform section. The overall cable lifting mechanism is modular and mounted on the side of the boat based on the mounting base. The distance and height of the lateral telescopic slide section relative to the mounting base are adjustable. The lifting slide section is slidably connected to the lateral telescopic slide section and its vertical lifting position is controllable. The lifting platform section is slidably disposed within the lifting slide section, and its vertical lifting position is controllable.
[0006] Furthermore, a plurality of hinge plates are provided between the mounting base plate and the lateral telescopic slide section. The two sides of the plurality of hinge plates are respectively hinged to the mounting base plate and the lateral telescopic slide section to form a deformable parallelogram structure. A first hydraulic rod for controlling the deformation is also provided between the mounting base plate and the lateral telescopic slide section. One end of the first hydraulic rod is hinged to the mounting base plate and the other end is hinged to the lateral telescopic slide section.
[0007] Furthermore, the lateral telescopic slide section includes a long strip-shaped first track and a second hydraulic rod. The first track is arranged parallel to the mounting base plate and serves as a guide track for the longitudinal lifting and lowering movement of the lifting slide section. The second hydraulic rod is provided inside the first track, with one end of the second hydraulic rod fixed inside the first track and the free end of the second hydraulic rod connected to the lifting slide section.
[0008] Furthermore, the lifting slide section is provided with a second track, and the lifting platform section slides along the second track; the lifting slide section is provided with a chain drive section for driving the lifting platform section to move.
[0009] Furthermore, the chain drive unit includes sprockets arranged at the upper and lower ends of the second track, with a chain sleeved on the two sprockets, and one side of the chain connected to the lifting platform unit.
[0010] Furthermore, the lifting platform includes a lifting slider and a side platform. The lifting slider is slidably connected and placed inside the second track, and the side platform is connected to the lifting slider and placed outside the second track.
[0011] Furthermore, the lifting platform is configured to be driven by a second hydraulic rod and then driven by a chain drive unit to achieve a double-speed lifting control.
[0012] The advantages and beneficial effects of this utility model are as follows: This device, through the parallelogram structure formed by the hinged plate and the cooperation of the first hydraulic rod, can achieve flexible folding and storage and lateral unfolding of the lateral telescopic slide section. When unfolded, it can keep the lifting mechanism away from the hull, effectively avoiding cable rubbing against the hull and providing a safe space for maintenance operations; when retracted, the mechanism can be stored on the side, saving space, facilitating the navigation and storage of the maintenance boat, and improving the practicality and safety of the equipment. Secondly, the multi-stage lifting design of the lifting slide section and the lifting platform section significantly enhances operational capabilities. The lifting slide section can rise and fall vertically relative to the lateral telescopic slide section, while the lifting platform section can slide and rise within the lifting slide section. Through three-step descent, the lifting platform section can be submerged to a sufficient depth in the water, facilitating underwater cable laying. Reverse operation can lift the cable out of the water, meeting the needs of cable maintenance at different depths and greatly improving the convenience and applicability of maintenance. The transmission system combining a chain drive unit and a hydraulic rod enables double-speed lifting control. When the second hydraulic rod drives the lifting slide unit, the secondary transmission of the chain drive unit causes the lifting platform and the lifting slide unit to move simultaneously, achieving a double-speed effect. This ensures lifting stability while significantly increasing lifting speed. It also allows for rapid response during emergency repairs, effectively shortening repair time, improving repair efficiency, and reducing losses caused by cable faults. Attached Figure Description

[0015] The specific embodiments of this utility model will be further described below with reference to examples. These examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.
[0016] A side cable lifting mechanism for a cable repair boat includes a mounting base plate 1, a lateral telescopic slide section 2, a lifting slide section 3, and a lifting platform section 4; as shown Figure 1-4 As shown, the overall cable lifting mechanism is modular and is installed on the side of the ship based on the mounting base plate 1. The distance and height position between the lateral telescopic slide section 2 and the mounting base plate 1 are adjustable.
[0017] Specifically, a plurality of hinge plates 5 are provided between the mounting base plate 1 and the lateral telescopic slide section 2. The two sides of each hinge plate 5 are respectively hinged to the mounting base plate 1 and the lateral telescopic slide section 2, forming a deformable parallelogram structure. In this embodiment, hinge plates 5 are respectively provided on the upper and lower sides of the mounting base plate 1, with the two hinge plates 5 arranged in parallel. The other end of each hinge plate 5 is hinged to the lateral telescopic slide section 2, forming a parallelogram structure. Since the mounting base plate 1 serves as the foundation for fixed connection to the hull, when the hinge plates 5 are rotated outwards to open, the lateral telescopic slide section 2 can move away from the mounting base plate 1 while simultaneously moving downwards a certain distance. Conversely, when the lateral telescopic slide section 2 retracts, it moves closer to the mounting base plate 1 and simultaneously lifts upwards, achieving a folding and storage effect. A first hydraulic rod 6 for controlling deformation is also provided between the mounting base plate 1 and the lateral telescopic slide section 2. One end of the first hydraulic rod 6 is hinged to the mounting base plate 1, and the other end is hinged to the lateral telescopic slide section 2. The folding and retraction or lateral unfolding of the lateral telescopic slide section 2 is controlled by extending and retracting the first hydraulic rod 6.
[0018] When the lateral telescopic slide moves horizontally to the outside of the ship's side, the lifting mechanism can extend horizontally away from the ship's side rotation, thereby increasing the lateral distance between the lifting mechanism and the ship's hull. This prevents the cable from rubbing against the ship's hull while the ship is moving or when the cable is being repaired. It also makes it easier to extend or retract the lifting mechanism into the side of the ship for convenient storage.
[0019] The lifting slide section 3 is slidably connected to the lateral telescopic slide section 2 and its vertical lifting position is controllable. Specifically, the lateral telescopic slide section 2 includes a long strip-shaped first track 7 and a second hydraulic rod 8. The first track 7 is a long strip-shaped groove and is arranged parallel to the mounting base plate 1. The first track 7 is a guide track for the longitudinal lifting movement of the lifting slide section 3. The second hydraulic rod 8 is provided in the first track 7. One end of the second hydraulic rod 8 is fixed in the first track 7, and the free end of the second hydraulic rod 8 is connected to the lifting slide section 3. The long strip-shaped groove-shaped first track 7 is arranged in the vertical direction, thereby guiding the movement of the lifting slide section 3 and limiting its movement stroke. The hydraulic cylinder of the second hydraulic rod 8 is fixedly installed inside the first track 7. The free end of the second hydraulic rod 8 extends downward and the lower end is connected to the lifting slide section 3. A chain drive tooth 15 is fixedly installed on one side of the first track 7. The chain drive tooth 15 is used to drive the chain drive section 10 installed inside the lifting slide section 3 to rotate. The movement of the lifting slide relative to the first track 7 is used as the power to drive the chain to rotate.
[0020] Furthermore, a lifting platform 4 is slidably provided within the lifting slide section 3, and the lifting platform 4 is controlled to move vertically. Specifically, a second track 9 is provided within the lifting slide section 3, and the lifting platform 4 slides along the second track 9; a chain drive section 10 is provided within the lifting slide section to drive the movement of the lifting platform 4. Similar to the first track 7, the second track 9 is also arranged vertically, thus providing guidance for the movement of the lifting platform 4. In actual use, the first step of unfolding and moving downward is achieved by the lateral expansion and downward movement of the lateral telescopic slide section 2; then the lifting slide section 3 slides down to the bottom of the first track 7 to achieve the second step of downward movement; then the lifting platform 4 moves down to the bottom of the second track 9 to form the third step of downward movement, thereby allowing the lifting platform 4 to be immersed in water to a sufficient depth; furthermore, the lifting platform 4 includes a lifting slider 13 and a side platform 14, the lifting slider 13 is slidably connected and placed within the second track 9, and the side platform 14 is connected to the lifting slider 13 and placed outside the second track 9. Since the side platform 14 is lowered to a sufficient depth underwater, the cable in the water can be laid on the side platform 14. Then, the lifting platform 4 is raised to the top by reverse control, thereby lifting the submerged cable out of the water and making it convenient for the staff on the cable repair boat to carry out maintenance operations.
[0021] The chain drive unit 10 includes sprockets 11 at the upper and lower ends of the second track 9, with chains mounted on the two sprockets 11. One side of the chain is connected to the lifting platform unit 4. Furthermore, the lifting platform unit 4 is configured to be driven by a second hydraulic rod 8 and then driven by the chain drive unit 10 in a two-stage transmission to achieve double-speed lifting control. In actual use, the lifting platform unit 4 and the lifting slide unit 3 are simultaneously driven by the second hydraulic rod 8. When the second hydraulic rod 8 drives the lifting slide unit 3 to move, the first track 7 and the second track 9 move relative to each other. The arrangement of the sprockets 11 and the chain connects the chain drive teeth 15 to one side of the chain, while the other side of the chain is connected to the lifting slider 13. Therefore, the simultaneous movement of the lifting platform unit 4 and the lifting slide unit 3 can be controlled by the extension and retraction of the second hydraulic rod 8.
[0022] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
