[0023] Typical embodiments embodying the features and advantages of this utility model will be described in detail in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.

[0026] This application provides a protective maintenance platform for use in the construction, maintenance, and management of ships and marine engineering projects, to assist staff in inspecting and maintaining related equipment.

[0027] The following detailed description, in conjunction with the accompanying drawings, provides a specific embodiment of the protection and maintenance platform of this application.

[0028] Figure 1 This is a three-dimensional structural diagram of the protection and maintenance platform in this embodiment. Figure 2 for Figure 1 Side view of the central protective maintenance platform along the AA direction. Figure 3 for Figure 1 Side view of the central protection and maintenance platform along the BB direction.

[0029] refer to Figures 1-3 The protective maintenance platform includes a base 1, a lifting mechanism 2, a rotating mechanism 3, a support platform 4, and a protective structure 5. The lifting mechanism 2 is mounted on the base 1 and includes a lifting end 21 that can be raised and lowered relative to the base 1. The rotating mechanism 3 is mounted on the lifting end 21. The rotating mechanism 3 includes a rotating shaft 32 with its axis extending vertically, and the rotating shaft 32 can rotate about its axis. The support platform 4 is mounted on the rotating shaft 32. The protective structure 5 is mounted circumferentially on the support platform 4 and protrudes upwards from the support platform 4.

[0030] In this application, under the action of the lifting mechanism 2 and the rotating mechanism 3, the support platform 4 can be lifted vertically and rotated circumferentially, thereby enabling flexible adjustment of the height and angle of the support platform 4. This allows the support platform 4 to be moved to the ideal angle area for maintenance work without moving the entire maintenance platform, bringing great convenience to the staff. Moreover, it eliminates the need for manual pushing of the entire maintenance platform, saving more time and effort.

[0031] Furthermore, the protective structure 5 arranged around the support platform 4 can provide safety protection for the staff on the support platform 4, preventing them from accidentally falling from the support platform 4 and causing injury, thus reducing safety hazards.

[0032] Figure 4 for Figure 2 A partial cross-sectional view of the central protection and maintenance platform.

[0033] In this embodiment, the base 1 includes a housing 11 and a vibration damping layer 12.

[0034] The top of the outer shell 11 extends horizontally, and the interior of the outer shell 11 is hollow. Specifically, the outer shell 11 is a cuboid structure formed by six plates connected end to end. This can reduce the weight of the base 1 while ensuring the structural strength of the base 1, so as to achieve the lightweighting of the protective maintenance platform and facilitate the transfer of the protective maintenance platform.

[0035] A vibration damping layer 12 is disposed inside the outer shell 11, with its upper and lower ends connected between the top and bottom walls of the outer shell 11. The vibration damping layer 12 is capable of vertical elastic expansion and contraction, providing elastic support between the top and bottom walls of the outer shell 11. This design utilizes the elastic expansion and contraction of the vibration damping layer 12 to absorb and disperse the impact energy from external forces applied to the protective maintenance platform by workers. Alternatively, this design can also absorb and disperse vibrations generated during manual movement of the protective maintenance platform, significantly reducing vibration amplitude, improving the support stability of the base 1, and thus enhancing the overall stability of the protective maintenance platform, ensuring the safety of workers during maintenance.

[0036] The vibration damping layer 12 includes multiple elastic support members 121, which are spaced apart inside the outer shell 11. The upper and lower ends of each elastic support member 121 are connected between the top and bottom walls of the outer shell 11, and each elastic support member 121 is elastically supported between the top and bottom walls of the outer shell 11. Optionally, the multiple elastic support members 121 are evenly distributed inside the outer shell 11 to ensure uniform stress on the top and bottom walls of the outer shell 11 and improve the stability of the base 1.

[0037] Specifically, the elastic support 121 is a spring damper.

[0038] For example, the elastic support 121 may include a guide rod 1212 and a spring 1211. The guide rod 1212 includes a main body and a telescopic part, which are sleeved and slidably connected to each other. The top of one of the main body and the telescopic part is connected to the top wall of the outer casing 11, and the bottom of the other is connected to the bottom wall of the outer casing 11. The spring 1211 is sleeved on the outer periphery of the guide rod 1212, and its axial ends are respectively connected to the main body and the telescopic part. The connection includes, but is not limited to, a fixed connection and a limiting connection. The main body and the telescopic part of the guide rod 1212 can slide relative to each other in the vertical direction. At the same time, the spring 1211 undergoes elastic deformation due to displacement in the vertical direction. During this process, the guide rod 1212 can guide and limit the spring 1211, so that the spring 1211 moves vertically to keep the elastic support 121 vertically supported between the top wall and the bottom wall of the outer casing 11.

[0039] Specifically, the bottom of the main body is connected to the bottom wall of the outer casing 11, and the top of the telescopic part is connected to the top wall of the outer casing 11. The top of the main body has an opening, through which the telescopic part extends into the main body and slides. Optionally, a guide sleeve is fitted around the outer periphery of the telescopic part, contacting the inner peripheral wall of the main body. The guide sleeve is made of a high-friction coefficient material. When the telescopic part slides relative to the main body, the friction between the guide sleeve and the inner peripheral wall of the main body generates a damping effect, converting the elastic potential energy accumulated by the deformation of the spring 1211 into heat energy dissipation. This prevents continuous oscillation when the spring 1211 returns to its original deformation, avoids the "jumping" phenomenon of the base 1, and improves the stability of the protective maintenance platform.

[0040] refer to Figures 1-4 In this embodiment, the lifting mechanism 2 is mounted on the base 1, and the lifting mechanism 2 includes a lifting end 21 that can be raised and lowered relative to the base 1. Specifically, the lifting mechanism 2 adopts a hydraulic electric lifting column, that is, the lifting mechanism 2 is driven by a hydraulic system, which facilitates the rapid response of the lifting action, improves the flexibility of the lifting mechanism 2, and also helps to improve the stability of the lifting, thereby improving the stability of the protective maintenance platform during the lifting process.

[0041] The system includes two lifting mechanisms 2, which are spaced apart on the base 1. Optionally, the two lifting mechanisms 2 are arranged symmetrically about the center line of the base 1 to ensure uniform force distribution.

[0042] The lifting end 21 is connected to a lifting platform 6. Specifically, the lifting platform 6 is horizontally fixed to the top of the lifting end 21 of the two lifting mechanisms 2. Optionally, the two lifting mechanisms 2 are arranged symmetrically about the center line of the lifting platform 6 to ensure uniform force distribution on the lifting platform 6.

[0043] The rotating mechanism 3 is located on the lifting end 21. Specifically, the rotating mechanism 3 is located on the lifting platform 6.

[0044] The rotating mechanism 3 includes a drive body 31 and a rotating shaft 32. The drive body 31 is driven to the rotating shaft 32, and the drive body 31 drives the rotating shaft 32 to rotate. Specifically, the drive body 31 is fixed to the bottom of the lifting platform 6 and is located between the two lifting mechanisms 2. The rotating shaft 32 passes vertically through the lifting platform 6 and protrudes upward from the lifting platform 6. The rotating shaft 32 is rotatably connected to the lifting platform 6. That is, the axis of the rotating shaft 32 extends vertically, and under the action of the drive body 31, the rotating shaft 32 can rotate around its axis.

[0045] In other embodiments, the rotating mechanism 3 can be fixed to the top of the lifting platform 6 with its rotating axis 32 facing upwards.

[0046] Optionally, in this embodiment, the rotating mechanism 3 may further include a bearing. Specifically, the bearing includes an outer ring and an inner ring that are rotatably connected, with the outer ring fitted around the outer periphery of the inner ring. A mounting hole is provided at the center of the lifting platform 6, and the bearing is disposed within the mounting hole. The outer periphery of the bearing's outer ring is fixedly connected to the peripheral wall of the mounting hole. The rotating shaft 32 passes through the inner ring of the bearing and is fixedly connected to the inner peripheral wall of the inner ring. This reduces the frictional resistance of the rotating shaft 32 and improves its rotational flexibility and stability. Alternatively, the bearing may be located at the top of the lifting platform 6, correspondingly above the mounting hole. That is, the outer ring is fixed to the top of the lifting platform 6, and the inner ring is correspondingly located above the mounting hole. The rotating shaft 32 passes through the mounting hole and the inner ring sequentially from bottom to top. In this case, a clearance is left between the peripheral wall of the mounting hole and the rotating shaft 32 to avoid interference with the rotation of the rotating shaft 32, reduce frictional resistance, and improve the rotational flexibility of the rotating shaft 32.

[0047] The support platform 4 is mounted on the rotating shaft 32 and can rotate with the rotating shaft 32 to achieve angle adjustment. The support platform 4 is positioned above the lifting platform 6, with a clearance between them to prevent frictional resistance and interference with the rotation of the support platform 4. This reduces frictional resistance, improves the efficiency, stability, and flexibility of the rotating mechanism 3, and ensures smooth and stable rotation of the support platform 4. Specifically, the support platform 4 is positioned directly above the lifting platform 6, and the axis of the rotating shaft 32 vertically passes through the center of both the support platform 4 and the lifting platform 6, helping to balance the circumferential forces on the support platform 4 and improve its stability.

[0048] The top of the rotating shaft 32 is flush with the top of the inner ring. Both the top of the rotating shaft 32 and the top of the inner ring are fixed to the support platform 4 to increase the contact area with the support platform 4, which helps to improve the stability of the support platform 4. The inner ring of the bearing can protrude upward beyond the outer ring so that the support platform 4 is positioned above the outer ring at intervals. This avoids frictional resistance generated by the contact between the support platform 4 and the outer ring, which would interfere with the rotation of the support platform 4. This reduces frictional resistance, improves the efficiency, stability, and flexibility of the rotating mechanism 3, and ensures the smoothness and stability of the rotation of the support platform 4.

[0049] Figure 5 This is a cross-sectional view of a partial structure of the protection and maintenance platform in this embodiment.

[0050] refer to Figure 5 The support platform 4 includes a housing 41 and a load-bearing plate 42 disposed inside the housing 41. The load-bearing plate 42 abuts against and supports the bottom wall and top wall of the housing 41, which can improve the load-bearing capacity of the support platform 4 and avoid accidents.

[0051] In other embodiments, the housing 41 and the load-bearing plate 42 can also be integrally formed so that the support platform 4 is a solid platform.

[0052] refer to Figures 1-5 The protective structure 5 is installed on the support platform 4 along the circumference of the support platform 4 and protrudes upward from the support platform 4. The protective structure 5 can provide safety protection for the staff on the support platform 4, prevent the staff from accidentally falling from the support platform 4 and causing injury, and reduce safety hazards.

[0053] The protective structure 5 includes a protective body 51 and side doors 52. The protective body 51 has an opening on at least one side, and at least one side door 52 is movably provided on the protective body 51. Each side door 52 is used to open and close one opening of the protective body 51, facilitating personnel entry and exit from the overall structure formed by the protective structure 5 and the support platform 4. Specifically, the protective body 51 has an opening on one side. The side door 52 includes two door bodies 521, each rotatably connected to the opening end of the protective body 51. For example, the two door bodies 521 can rotate in opposite directions to open the opening of the protective body 51, or they can rotate in opposite directions to close the opening of the protective body 51.

[0054] refer to Figure 5 Optionally, the top of the support platform 4 is provided with an insulating layer 7. The insulating layer 7 is made of insulating material, which can isolate electrical transmission and prevent leakage and electric shock. The insulating layer 7 extends circumferentially to the inner peripheral wall of the protective structure 5, and completely covers the top surface of the support platform 4 that is not covered by the protective structure 5, so as to ensure that the area where the staff stands is insulated.

[0055] Specifically, the insulating layer 7 can be a plate-like structure made of insulating material, or it can be a film structure formed by spraying an insulating coating directly onto the top surface of the support platform 4.

[0056] Optionally, the top of the support platform 4 is provided with an anti-slip layer 8. The anti-slip layer 8 is made of anti-slip material, which increases friction to prevent workers from slipping accidentally and ensure their safety. The anti-slip layer 8 is located above the insulation layer 7 and extends circumferentially to the inner peripheral wall of the protective structure 5, completely covering the top surface of the support platform 4 that is not covered by the protective structure 5, so as to ensure that the area where workers stand is treated with anti-slip measures.

[0057] Specifically, the anti-slip layer 8 can be a plate-like structure made of anti-slip material, or it can be a film structure formed by spraying anti-slip coating directly onto the top surface of the support platform 4.

[0058] In other embodiments, the insulating layer 7 and the anti-slip layer 8 can be integrally formed, that is, they can be made directly from materials that have both insulating and anti-slip properties, such as rubber.

[0059] Optionally, the surfaces of the protective structure 5 and the support platform 4 are respectively provided with an isolation layer 9. The isolation layer 9 is made of anti-corrosion material. Through the isolation layer 9, the surfaces of the protective structure 5 and the support platform 4 can be isolated from contact with the outside air, thereby improving the corrosion resistance of the maintenance platform.

[0060] Among them, the isolation layer 9 can be made of epoxy resin anti-corrosion material.

[0061] refer to Figure 3 The protective maintenance platform also includes a straight ladder 10, which is connected to the lifting end 21. The straight ladder 10 is arranged corresponding to the side door 52. The straight ladder 10 is used for workers to climb, providing convenience for workers to go up to the support platform 4 or down to leave the protective maintenance platform.

[0062] The top of the ladder 10 is vertically lower than the bottom of the support platform 4 to avoid obstructing the rotation of the support platform 4, thus ensuring that the support platform 4 can rotate smoothly. Furthermore, the ladder 10 extends downwards at least to the lower part of the lifting mechanism 2 to facilitate climbing by workers.

[0063] Specifically, the vertical ladder 10 includes multiple steps 101 arranged at vertical intervals, each step 101 for workers to step on. The lowest step 101 corresponds vertically to the lower part of the lifting mechanism 2 or the base 1, facilitating climbing. The vertical ladder 10 also includes two connecting beams 102, and all the steps 101 are vertically connected between the two connecting beams 102.

[0064] refer to Figures 1-4The protective maintenance platform also includes multiple casters 20, which are spaced apart at the bottom of the base 1 to assist in the movement of the protective maintenance platform and improve its convenience and operability. Specifically, casters 20 are provided at each of the four corners of the base 1 to improve the stability of the base 1.

[0065] Exemplarily, the movable wheel 20 includes a hinge base 201 and a roller 202. The hinge base 201 is rotatably connected to the bottom of the base 1 via a hinge shaft, which extends vertically to allow the hinge base 201 to rotate relative to the base 1 along the axis of the hinge shaft. The roller 202 is rotatably connected to the hinge base 201 via a rotating shaft that extends horizontally. The roller 202 can be cylindrical with its axial direction extending horizontally, thereby increasing the outer surface area of ​​the roller 202 and the contact area between the roller 202 and the supporting surface (e.g., the ground), thus improving the stability of the roller 202 in supporting the base 1. This design allows the roller 202 to roll along the supporting surface while simultaneously rotating its axis, enabling the roller 202 to turn, thus allowing the protective maintenance platform to turn during movement.

[0066] Optionally, at least one of the movable wheels 20 is equipped with a wheel brake. By operating the wheel brake, the movable wheel 20 can be locked to prevent it from sliding freely, thereby fixing the position of the protective maintenance platform and improving its stability. Alternatively, by operating the wheel brake, the movable wheel 20 can be unlocked so that it can rotate, thus assisting the protective maintenance platform in moving.

[0067] Specifically, the wheel brake is mounted on the hinge seat 201. It can move relative to the hinge seat 201 to abut against the outer surface of the movable wheel 20 to lock and restrict the rolling of the movable wheel 20, or move relative to the hinge seat 201 to move away from the outer surface of the movable wheel 20 to unlock and release the movable wheel 20, allowing the movable wheel 20 to roll.

[0068] In other words, the casters 20 can be universal casters with wheel brakes, which facilitates turning during movement and helps improve the convenience and operability of the mobile protection and maintenance platform.

[0069] Optionally, the protective maintenance platform also includes a warning light 30, which is located on the top of the protective structure 5. The warning light 30 can emit a warning signal to indicate that the staff is carrying out maintenance work on the support platform 4, thereby improving the safety of the staff.

[0070] Optionally, the protective maintenance platform also includes a storage box 40, which is mounted on the protective structure 5. The storage box 40 has an internal storage space for storing maintenance tools, etc., to facilitate the access of maintenance tools by personnel located on the support platform 4. Specifically, the storage box 40 is located on the side of the protective body 51 opposite to the side door 52. The storage box 40 includes a box body and a lid. The top opening of the box body is hollow to form a storage space. The lid is rotatably or detachably mounted on the top of the box body and is used to open and close the top opening of the box body.

[0071] As can be seen from the above technical solution, this utility model has at least the following advantages and positive effects: In this application, the lifting and rotating mechanisms enable the support platform to be lifted vertically and rotated circumferentially, allowing for flexible adjustment of the support platform's height and angle. This allows the support platform to be moved to the ideal angle for maintenance work without moving the entire maintenance platform, greatly improving convenience for workers. Furthermore, it eliminates the need for manual pushing of the entire maintenance platform, saving time and effort.

[0072] Furthermore, the protective structure arranged around the circumference of the support platform can provide safety protection for the staff on the support platform, preventing them from accidentally falling from the support platform and causing injury, thus reducing safety hazards.

[0073] Although the present invention has been described with reference to several typical embodiments, it should be understood that the terminology used is descriptive and exemplary, and not restrictive. Since the present invention can be embodied in many forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims.
