[0002] In the current field of shipbuilding and marine engineering, outreach platforms are widely used as an important component for achieving observation and passage functions.

[0003] Traditional outreach platforms typically use electric or mechanical drives. Electric drive structures rely on external power supply, and in the complex marine environment, once a power failure occurs, the platform is difficult to open or close normally. Traditional mechanical transmission structures require manual operation of multiple components, which is cumbersome and not only increases the labor intensity of the staff, but also makes it difficult to achieve rapid platform response and meet the opening or closing needs in emergency situations. Utility Model Content

[0004] The purpose of this invention is to provide a hydraulically driven hinged outrigger platform device, which solves the problems of existing outrigger platforms that typically use electric or mechanical drives. Electric drive structures rely on external power supply, and in complex marine environments, the platform is difficult to open or close normally in the event of a power outage. Traditional mechanical transmission structures require manual operation of multiple components, which is cumbersome and increases the labor intensity of workers. It also makes it difficult to achieve rapid platform response and meet the opening or closing needs in emergency situations.

[0005] To achieve the above objectives, this utility model provides a hydraulically driven hinged outward-extending platform device, including a platform body, a base, a drive assembly, a door panel, and a handrail link. The drive assembly includes a manual pump and a hydraulic cylinder, both of which are mounted above the platform body. The manual pump is positioned on the surface of the hydraulic cylinder. The base is mounted above the platform body. The door panel is hinged to one side of the platform body. One end of the handrail link is fixedly mounted to one side of the platform body.

[0010] The platform body has a step fixedly installed on one side, and the upper surface of the step is flush with the patterned aluminum plate.

[0011] The active rotating shaft is fitted with a rotating bushing, which is rotatably connected to the base. A crank is welded to one end of the rotating bushing, and the other end of the crank is hinged to the output end of the hydraulic cylinder.

In this utility model, by adopting a hydraulic drive structure of manual pump and oil cylinder, combined with the linkage design of active rotating shaft, rotating bushing and crank, the platform body is driven to rotate by lever principle. It does not rely on external power supply and can still operate stably even in complex working conditions such as power failure. At the same time, the operation steps are simplified. The staff only need to operate the manual pump to realize the platform to open and close quickly, which greatly reduces the labor intensity and solves the problems of low reliability and cumbersome operation of traditional drive methods.

[0016] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0017] Please see Figure 1 - Figure 5As shown, a hydraulically driven hinged outward-extending platform device includes a platform body 14, a base 12, a drive assembly 5, a door 1, and a handrail link 3. The drive assembly 5 includes a manual pump 52 and a hydraulic cylinder 51. Both the manual pump 52 and the hydraulic cylinder 51 are installed above the platform body 14. The manual pump 52 is disposed on the surface of the hydraulic cylinder 51. The base 12 is installed above the platform body 14. The door 1 is hinged to one side of the platform body 14. One end of the handrail link 3 is fixedly installed on one side of the platform body 14. The platform body 14, base 12, drive assembly 5, door 1, and handrail link 3 constitute the core framework of the device. During operation, the base 12 is first fixed to the steel structure of the ship or marine engineering with bolts. The manual pump 52 on the platform body 14 is operated to deliver pressurized oil to the cylinder 51, which generates driving force at the output end of the cylinder 51. This drives the subsequent linkage components to rotate the platform body 14 around the base 12 to open it. Reverse operation of the manual pump 52 can close the platform. The door 1 can be independently hinged to open or close for personnel to enter and exit. One end of the handrail link 3 is fixed to the platform body 14. Its functions are as follows: the platform body 14 serves as a load-bearing carrier to provide the foundation for component installation; the base 12 ensures a stable connection between the device and the external structure; the manual pump 52 and the cylinder 51 constitute a hydraulic power source that does not rely on electricity, adapting to marine power outage conditions and shortening the hydraulic circuit to reduce pressure loss; the door 1 improves the flexibility of passage; and the handrail link 3 lays the foundation for the subsequent protective structure to ensure personnel safety. A railing seat 11 is fixedly installed on the upper surface of the platform body 14, and a railing 10 is fixedly installed on the upper surface of the railing seat 11. Both the railing seat 11 and the railing 10 are made of stainless steel, and the other end of the handrail connecting rod 3 is fixedly connected to the railing 10. The other end of the handrail link 3 is welded to the railing 10, forming a closed-loop protective frame with the handrail link 3, railing 10, railing base 11, and platform body 14. The stainless steel railing base 11 and railing 10 rely on their surface oxide film for corrosion protection in the high-salt-spray marine environment. Workers can rely on the railing 10 or handrail link 3 to prevent falls while working on the platform. The stainless steel railing 10 and railing base 11 effectively prevent falls, especially crucial during ship turbulence and wave impacts. The handrail link 3 increases the number of protective points, improving stability for personnel movement. The stainless steel material solves the problem of easy corrosion associated with traditional carbon steel, extending service life and reducing maintenance costs. Simultaneously, the railing 10 structure forms an integral part with the platform body 14, indirectly increasing the structural rigidity of the platform body 14 and reducing deformation. An active rotating shaft 8 is welded to one side of the platform body 14, with the other end rotatably connected to the base 12.The active rotating shaft 8 is welded to the platform body 14 and can rotate freely with the base 12, thereby driving the platform body 14 to rotate around the center of the shaft hole of the base 12. During the rotation, the clearance fit between the active rotating shaft 8 and the shaft hole of the base 12 ensures flexible rotation. The active rotating shaft 8, made of carbon steel, can bear the weight of the platform body 14, personnel, and components. Its function is that the active rotating shaft 8, as the core transmission component connecting the platform body 14 and the base 12, converts the power of the hydraulic cylinder 51 into the rotational motion of the platform, which is the key to realizing the platform's outward extension function. The high strength characteristics of the carbon steel material ensure that it is not easily damaged during long-term load-bearing and rotation, ensuring the stability of the platform's operating structure. Moreover, the fitting precision between the rotating shaft and the base 12 determines the smoothness of the platform's rotation, avoiding jamming that affects the user experience.

[0018] Please see Figure 1 - Figure 5As shown, a positioning plate 9 is fixedly installed on one side of the base 12, and a locking device 2 is fixedly installed on one end of the positioning plate 9. When the platform body 14 is closed and reset, the locking device 2 can be operated to lock the platform body 14 and the positioning plate 9. The positioning plate 9 provides installation support and positioning reference for the locking device 2, ensuring that the locking device 2 can accurately cooperate with the platform body 14. Its function is to firmly fix the platform body 14 after the platform is closed, to avoid the platform shaking caused by the ship's turbulence or the impact of ocean waves, and to eliminate safety hazards. The positioning plate 9 ensures that the locking device 2 is installed in a precise position, ensuring that it can be stably locked after each platform closure, improving the overall operational safety of the device. Especially in the dynamic environment of long-term ship navigation, this structure can maintain the stability of the platform in the closed state. The upper surface of the platform body 14 is covered with a patterned aluminum plate 4, which is fixedly connected to the platform body 14 by rivets. The surface of the patterned aluminum plate 4 is provided with raised texture. The patterned aluminum plate 4 is fixed to the upper surface of the platform body 14 by rivets. The raised texture on the surface increases the friction between the personnel's feet and the aluminum plate. The rivet connection ensures that the patterned aluminum plate 4 and the platform body 14 are firmly attached, preventing loosening during long-term use. Its function is to effectively prevent workers from slipping when walking or working on the platform, especially in marine environments where the platform surface is prone to seawater and moisture, where the anti-slip effect is even more critical. The rivet connection ensures the aluminum plate is installed stably. At the same time, the patterned aluminum plate 4 is lightweight, which increases the protective function without excessively increasing the load on the platform body 14. The aluminum plate also has a certain degree of corrosion resistance, making it suitable for marine use. A step 13 is fixedly installed on one side of the platform body 14, and the upper surface of the step 13 is flush with the patterned aluminum plate 4. Personnel can use steps 13 to transition when going up and down the platform, avoiding tripping due to height differences. The purpose of these steps is to create a smooth passageway between the level steps 13 and the patterned aluminum plate 4, facilitating personnel access to and from the platform. This is especially beneficial when carrying tools and equipment, reducing obstruction and tripping risks, and improving the convenience and safety of platform use. Furthermore, the fixed installation structure of steps 13 can withstand the weight of personnel and tools, resisting deformation over long-term use, and is suitable for the frequent personnel passage requirements in marine engineering. A rotating bushing 6 is fitted onto the surface of the active rotating shaft 8. The rotating bushing 6 is rotatably connected to the base 12. A crank 7 is welded to one end of the rotating bushing 6, and the other end of the crank 7 is hinged to the output end of the hydraulic cylinder 51.The rotating bushing 6 is fitted onto the surface of the drive shaft 8 and forms a rotatable connection with the base 12. One end of the crank 7 is welded to the rotating bushing 6, and the other end is hinged to the output end of the hydraulic cylinder 51. When the output end of the hydraulic cylinder 51 extends or retracts, it drives the crank 7 to rotate around the center of the rotating bushing 6, thereby driving the rotating bushing 6 to rotate synchronously with the drive shaft 8, ultimately realizing the rotation of the platform body 14. Its function is that the rotating bushing 6 can reduce the direct friction between the drive shaft 8 and the base 12, reduce component wear, and extend the service life of the drive shaft 8. The crank 7, as a power transmission medium, converts the linear driving force of the hydraulic cylinder 51 into rotational force, improves the power transmission efficiency, makes the rotation process of the platform body 14 more stable, avoids power loss or component impact caused by direct transmission, and ensures the smoothness of the platform opening and closing actions.

[0019] Working Principle: In practical applications, this hydraulically driven hinged outward-extending platform requires the base 12 to be fixed to the steel structure of the ship or marine engineering project to complete the overall installation. When the platform needs to be opened, the operator operates the manual pump 52 on the platform body 14. The manual pump 52 provides hydraulic power to the cylinder 51, pushing the output end of the cylinder 51 to extend. The output end of the cylinder 51 drives the crank 7, which is hinged to it, to rotate. The crank 7 drives the rotating sleeve 6, which is sleeved on the drive shaft 8, to rotate synchronously. This, in turn, drives the platform body 14 to rotate around the base 12 through the drive shaft 8, thus opening the platform. During the opening process, the railing 10 and the handrail connecting rod 3 form a protective structure to ensure the safety of the operators. The patterned aluminum plate 4 on the platform body 14 increases friction through raised textures to prevent slipping, while the steps 13 facilitate the operator's entry and exit from the platform. When the platform is opened to the required angle or fully opened, the manual pump 52 is stopped, the cylinder 51 remains in its current state, and the platform remains stable. When the platform needs to be shut down, the manual pump 52 is operated in reverse, the output end of the cylinder 51 is retracted, and the crank 7, rotating bushing 6 and drive shaft 8 are rotated in reverse, so that the platform body 14 is gradually reset. After the platform is completely shut down, the platform body 14 is firmly fixed by the locking device 2 at one end of the positioning plate 9 on the base 12 to prevent the platform from shaking under conditions such as ship sailing and turbulence, and to ensure the safe operation of the device.
