Description

Technical Field

[0001] This application relates to the technical field of floating platform lifting, and in particular to a floating platform lifting machine. Background Technology

[0002] A floating crane is a type of crane that mounts a large crane on a floating platform, enabling it to move on the water surface and perform lifting operations. This allows it to perform water-based operations that are inaccessible or difficult for shore-based cranes to handle. The integrated floating water supply float with announcement number CN222329969U currently includes a floating platform, a lifting frame, three suspended submersible pumps, multiple floats, and a ladder. A placement trough is located near the center of the upper surface of the ladder, and three gate valves are installed on one side of the placement trough. The floating platform is then allowed to float to the center of the water area, where the suspended submersible pumps inside the platform extract mud from the water.

[0003] Regarding the aforementioned technologies, the lifting frame is installed in the middle of the floating platform, that is, the lifting frame is installed directly above the three hanging submersible pumps, while the three hanging submersible pumps are located below the floating platform. When installing the hanging submersible pumps, the lifting frame will be located in the path of the hanging submersible pumps, which makes it inconvenient to lift the hanging submersible pumps. Utility Model Content

[0004] To facilitate the lifting of objects, this application provides a floating platform crane.

[0005] The floating platform crane provided in this application adopts the following technical solution: A floating platform crane, comprising: A floating platform, wherein a placement hole is provided in the middle of the floating platform; The lifting device includes two lifting frames symmetrically arranged about the placement hole and a driving member for driving the lifting frames to move. One end of the lifting frame is rotatably connected to the floating platform, and one end of the driving member is hinged to the floating platform and the other end is hinged to the lifting frame to drive the lifting frame to rotate. The lifting devices are installed one-to-one on the lifting frame.

[0006] By adopting the above technical solution, when it is necessary to lift an object, the drive unit drives the lifting frame to rotate away from the placement hole, so that the object can pass smoothly above the placement hole. The object is then fixed with a lifting device. Then, the drive unit drives the lifting frame to rotate towards the placement hole. At this time, the object will slowly move towards the placement hole. When the lifting frame moves to the limit position, the lifting device is then driven to lower the object.

[0007] Because the lifting frame is away from directly above the placement hole when lifting the object, it is easier to place the object from directly above the placement hole, which in turn makes it easier for the lifting equipment to lift the object.

[0008] Optionally, a mounting frame is fixedly connected to the floating platform, the lifting frame is hinged to the mounting frame, the mounting frame is provided with a mounting boss, the driving component is a driving electric cylinder, one end of the driving electric cylinder is hinged to the mounting boss, and the other end is hinged to the lifting frame.

[0009] By adopting the above technical solution, the installation of the mounting frame and the mounting boss facilitates the hinged connection of the lifting frame to the mounting frame. At the same time, the installation boss facilitates the tilting hinge of the electric cylinder to the lifting frame, which in turn facilitates the electric cylinder to drive the lifting frame to rotate.

[0010] Optionally, a limiting rod is fixedly connected to the side of the mounting bracket away from the mounting boss, and the limiting rod is located on the movement path of the mounting bracket.

[0011] By adopting the above technical solution, the setting of the limiting rod allows the mounting frame to be supported after it rotates to the limit position, thereby reducing the damage to the mounting frame and the drive electric cylinder during the hoisting process.

[0012] Optionally, a limiting groove is provided at the top of the limiting rod, and the mounting bracket can rotate into the limiting groove.

[0013] By adopting the above technical solution, the setting of the limiting groove makes the mounting bracket more stable when it abuts against the limiting groove.

[0014] Optionally, the lifting frame is fixedly connected to a mounting lug, and the lifting device is fixedly connected to a hoisting lug, wherein the hoisting lug is hinged to the mounting lug.

[0015] By adopting the above technical solution and utilizing the cooperation of the mounting lugs and lifting lugs, the lifting device can adjust its force angle under gravity during the lifting process, adapt to the swing or position change of the lifted object, reduce stress concentration, and improve the flexibility and safety of the lifting process.

[0016] Optionally, an outer fence is installed on the outer edge of the floating platform.

[0017] By adopting the above technical solutions, the outer fence prevents personnel or objects from falling from the edge of the floating platform, thus increasing operational safety.

[0018] Optionally, the floating platform is fitted with an inner fence near the inner edge of the placement hole.

[0019] By adopting the above technical solution, the inner fence prevents people or objects from falling into the placement holes, further enhancing safety.

[0020] Optionally, the floating platform includes a float and a mounting plate, the float being located below the mounting plate, and the lifting component being mounted on the mounting plate.

[0021] By adopting the above technical solution, a stable buoyancy is provided by a float, and an installation plate is then installed on the float. The installation plate provides a sturdy installation platform, which facilitates the installation of lifting components and ensures the stability of the lifting component installation.

[0022] In summary, this application includes at least one of the following beneficial technical effects: Through the cooperation of the floating platform, placement hole, lifting frame, drive unit and lifting device, when it is necessary to lift the object, the drive unit drives the lifting frame to rotate away from the placement hole, so that the object can pass smoothly above the placement hole, thus making it easier to place the object directly above the placement hole, thereby facilitating the lifting device to lift the object. The mounting bracket and mounting boss work together to facilitate the hinged connection of the lifting frame to the mounting bracket. At the same time, the mounting boss facilitates the tilting hinge of the electric cylinder to the lifting frame, which in turn facilitates the electric cylinder to drive the lifting frame to rotate. The combination of the limiting rod and the limiting groove allows the mounting frame to be supported after it rotates to its limit position, thereby reducing damage to the mounting frame and the drive cylinder during the hoisting process. At the same time, the limiting groove makes the mounting frame more stable when it abuts against the limiting groove. Attached Figure Description

[0029] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0030] This application discloses a floating platform crane.

[0031] Reference Figure 1-5 A floating platform crane includes a floating platform 1, lifting components 2, and lifting devices 3. The floating platform 1 has a placement hole 4 in the middle. The lifting component 2 includes two lifting frames 21 symmetrically arranged about the placement hole 4 and a driving component 22 for moving the lifting frames 21. One end of each lifting frame 21 is rotatably connected to the floating platform 1, and one end of each driving component 22 is hinged to the floating platform 1, while the other end is hinged to the lifting frame 21. The lifting devices 3 are installed one-to-one on the lifting frames 21. Because the lifting frames 21 are located away from directly above the placement hole 4 when lifting the object, it is convenient to place the object directly above the placement hole 4, thus facilitating the lifting device 3 in lifting the object.

[0032] In this embodiment, the floating platform 1 includes a float 11 and a mounting plate 12. The float 11 is located below the mounting plate 12, and the lifting component 2 is mounted on the mounting plate 12. The float 11 provides stable buoyancy, and the mounting plate 12 is then mounted on the float 11. The mounting plate 12 provides a robust mounting platform, facilitating the installation of the lifting component 2 and ensuring the stability of the lifting component 2 during installation.

[0033] To ensure safety during operations on the floating platform 1, an outer guardrail 5 is installed along the outer edge of the mounting plate 12, and an inner guardrail 6 is installed along the inner edge of the mounting plate 12 near the placement hole 4. The outer guardrail 5 prevents personnel or objects from falling from the edge of the floating platform 1, increasing operational safety. Simultaneously, the inner guardrail 6 prevents personnel or objects from falling into the placement hole 4, further enhancing safety.

[0034] Mounting bracket 7 is fixedly connected to mounting plate 12, and lifting bracket 21 is hinged to mounting bracket 7. The mounting bracket 7 is designed to facilitate the hinged connection of lifting bracket 21 to mounting bracket 7.

[0035] The mounting bracket 7 is provided with a mounting boss 71, and the driving component 22 is a driving electric cylinder. One end of the driving electric cylinder is hinged to the mounting boss 71, and the other end is hinged to the lifting frame 21. The mounting boss 71 is provided to facilitate the tilting hinge of the driving electric cylinder to the lifting frame 21, so as to facilitate the driving electric cylinder to drive the lifting frame 21 to rotate.

[0036] In an optional embodiment, a limiting rod 8 is fixedly connected to the side of the mounting bracket 7 away from the mounting boss 71, and the limiting rod 8 is located on the movement path of the mounting bracket 7. The limiting rod 8 is provided so that after the mounting bracket 7 rotates to its extreme position, the limiting rod 8 can support the mounting bracket 7, thereby reducing damage to the mounting bracket 7 and the drive electric cylinder during the hoisting process.

[0037] In this embodiment, a limiting groove 81 is provided at the top of the limiting rod 8, and the mounting bracket 7 can rotate into the limiting groove 81. The limiting groove 81 makes the mounting bracket 7 more stable when it abuts against the limiting groove 81.

[0038] The lifting frame 21 is fixedly connected to a mounting lug 9, and the lifting device 3 is fixedly connected to a lifting lug 91, which is hinged to the mounting lug 9. By utilizing the cooperation between the mounting lug 9 and the lifting lug 91, the lifting device 3 can adjust its force angle under gravity during the lifting process, adapting to the swing or positional changes of the lifted object, reducing stress concentration, and improving the flexibility and safety of the lifting process.

[0039] The implementation principle of a floating platform hoist in this application embodiment is as follows: When it is necessary to hoist an object, the drive cylinder drives the hoisting frame 21 to rotate away from the placement hole 4, so that the object can pass smoothly above the placement hole 4. Then, the object is fixed by the hoisting device 3. Next, the drive cylinder drives the hoisting frame 21 to rotate towards the placement hole 4. At this time, the object will slowly move towards the placement hole 4. When the hoisting frame 21 moves to the limit position, the hoisting device 3 is driven to lower the object, thereby completing the hoisting of the object.

[0040] Since the lifting frame 21 is away from the top of the placement hole 4 when lifting the object, it is convenient to place the object from the top of the placement hole 4, which in turn makes it easier for the lifting device 3 to lift the object.

[0041] 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.
