[0040] The technical solution of the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can better understand the present invention and implement it. However, the embodiments given do not limit the present invention. In this embodiment, it should be understood that the directions or positional relationships indicated by terms such as "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", and "outside" are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention.

[0041] It should be noted that when an element is considered to be "connected" to another element, it may be directly connected to the other element and integrated therewith, or there may be an intermediate element. The terms "mounted," "one end," "the other end," and similar expressions used in this invention are for illustrative purposes only.

[0042] This embodiment provides an offshore platform operation equipment, such as Figures 1 to 5 As shown, it includes a base 100, an operating table 200 and a magnetic operation unit. The operating table 200 and the magnetic operation unit are both arranged on the base 100. The magnetic operation unit includes an operation auxiliary unit and a magnetic operation body 300.

[0043] The operation auxiliary unit includes a hoisting device 400 and a material storage device 500, both of which are connected to the base 100; the hoisting device 400 is used to lift the magnetic operation body 300 from the base 100 and suspend it to the operation height; the material storage device 500 is used to provide the magnetic operation body 300 with the materials required for the operation;

[0044] The magnetic operation body 300 includes a remote-controlled robot 310 , which can be attracted to the operation area of ​​the offshore platform to perform operations.

[0045] The present invention integrates the remote control robot 310, the hanging device 400, the material storage device 500 and the operating table 200 on the base 100, which not only avoids the scattered and disordered equipment but also enables convenient and quick transfer. The operating equipment of the present invention can be used at different operating points and reused, which is highly economical.

[0046] The present invention can suspend the remote-controlled robot 310 at the working height through the suspending device 400. The staff only needs to stand on the deck of the offshore platform to perform the corresponding operations. The remote-controlled robot 310 is adsorbed in the working area and performs the operation without direct manual operation, which greatly reduces the labor intensity and avoids the safety risks of workers working directly on the offshore platform. There is no need to set up an operating frame for workers to work in the air, which saves a lot of preparation and finishing work, greatly improves the working efficiency, and can solve the current problem that the maintenance work on the outer surface of the offshore platform is often done manually, which has the disadvantages of high labor intensity, long construction period, high cost, complex sea surface conditions and high risk factor.

[0047] It should be noted that the operating console 200 can be provided with an electric control box, a touch screen, a display screen, control buttons, etc., taking into account various electric control components, remote control function keys, etc., and can be integrated.

[0048] In a preferred embodiment, Figure 2 and Figure 3As shown, the magnetic operation body 300 also includes a deployment platform 330, which includes a telescopic ladder 340, a sliding platform 331 and a lifting platform 332. The lower end of the telescopic ladder 340 and the lower end of the lifting platform 332 are respectively connected to the sliding platform 331, and the remote-controlled robot 310 is arranged at the upper end of the lifting platform 332. The sliding platform 331 is provided with a first oil cylinder 333 that can extend and retract the sliding platform 331 in the horizontal direction, and the lifting platform 332 is provided with a second oil cylinder 334 that can move the remote-controlled robot 310 in the vertical direction. The upper end of the telescopic ladder 340 is used to be detachably connected to the base 100 when the deployment platform 330 is lifted off the base 100 and lowered. In this embodiment, a deployment platform 330 is provided for the remote-controlled robot 310. When suspending the magnetic operation body 300, the suspension point can be set on the deployment platform 330, which facilitates the suspension point setting and suspension operation. By controlling the extension and contraction action of the first oil cylinder 333, the sliding platform 331 can be pushed to move laterally, thereby realizing the lateral movement of the remote-controlled robot 310 in the suspended state. Similarly, by controlling the extension and contraction action of the second oil cylinder 334, the jacking platform 332 can be pushed to rise and fall vertically, thereby realizing the vertical movement of the remote-controlled robot 310 in the suspended state, thereby having better fine-tuning function, can better adapt to the bottom surface of the offshore platform or other concave special operation areas, and greatly improve the operation convenience in special operation areas.

[0049] It should be noted that if Figure 4 and Figure 5 As shown, when the deployment platform 330 is lifted off the base 100 and begins to be lowered, the upper end of the telescopic ladder 340 is detachably connected to the base 100. As the deployment platform 330 continues to be lowered vertically, the telescopic ladder 340 also continues to extend vertically. During this downward movement, the telescopic ladder 340 is detachably connected to the base 100. On the one hand, the lateral spacing between the telescopic ladder 340 and the base 100 is fixed, which can also fix the spacing between the deployment platform 330 and the offshore platform, preventing the deployment platform 330 from shaking due to being suspended only by the lifting device 400, which could affect the subsequent accurate and rapid adjustment of the remote control robot 310. On the other hand, when the operation is completed and the deployment platform 330 is pulled up to the deck height of the offshore platform deployment point and recovered, the telescopic ladder 340 can be separated from the base 100, and the deployment platform 330 can be completely stored back on the base 100.

[0050] In a further preferred embodiment, the remote-controlled robot 310 is provided with a magnetic module 320, and the remote-controlled robot 310 is inverted on the upper end of the jacking platform 332 so that the magnetic module 320 faces upward. When the space available for placing the remote-controlled robot 310 is located below the working surface, this embodiment can facilitate the remote-controlled robot 310 to be directly adsorbed and fixed to the working surface.

[0051] In a further preferred embodiment, the telescopic ladder 340 includes a ladder base 341 and a ladder body 342. The lower end of the ladder body 342 is hinged to the ladder base 341, and the upper end of the ladder body 342 is configured to be detachably connected to the base 100. The ladder base 341 is connected to the sliding platform 331. The sliding platform 331 is provided with a first support member 343, which is configured to support the ladder body 342 in an inclined state (i.e., a non-operating state). Specifically, the base 100 is provided with a fixing frame 140. The lower end of the fixing frame 140 is connected to the base 100, and the upper end of the fixing frame 140 is configured to be detachably connected to the upper end of the telescopic ladder 340. In a preferred embodiment, the lower end of the fixing frame 140 is hinged to the base 100 so that it can be laid down when not in use, freeing up a larger space to facilitate the back and forth lifting of the deployment platform 330; the fixing frame 140 is a tripod with a more stable structure, with a connecting plate 141 provided at the top, and the upper end of the ladder body 342 is connected to the connecting plate 141 by bolts. During operation, the end of the connecting plate 141 needs to extend out of the outer plate of the offshore platform so that the telescopic ladder 340 can maintain a vertical connection with the connecting plate 141.

[0052] In another preferred embodiment, the remote-controlled robot 310 includes a robot body, which is integrated with a signal transmission module, a navigation and positioning module, a high-pressure water cleaning system, a paint spraying system, a binocular recognition system, a corrosion detection system and a single-chip microcomputer. The signal transmission module, the navigation and positioning module, the high-pressure water cleaning system, the paint spraying system, the binocular recognition system and the corrosion detection system are respectively connected to the single-chip microcomputer signal. The above configuration of the remote-controlled robot 310 in this embodiment has a high degree of intelligence and can realize functions such as autonomous route planning, autonomous walking, detection, cleaning, and painting. It can realize unmanned, visual, and intelligent operations, and the operator can perform remote control operations through a wireless controller. The remote-controlled robot 310 can be specifically referred to the solution content of the patent application number 202311015385.4 and the patent name "Multifunctional intelligent detection and cleaning robot for the outside of the hull", which will not be repeated here.

The pipes and cables wound around the cable drum 510, the high-pressure water device 520, and the spray device 530 are respectively wound through the cable guide assembly 420 and connected to the remote-controlled robot 310. Among them, the cable drum 510 is used to store the power and communication cables of the remote-controlled robot 310, the high-pressure water device 520 is used to supply high-pressure water for cleaning and other purposes to the remote-controlled robot 310, the spray device 530 is used to supply paint for painting to the remote-controlled robot 310, and the sling drum 430 is used to store the slings.

[0054] Furthermore, the high-pressure water device 520 and the spraying device 530 are located on either side of the centerline of the crane 410, and the weight distribution is evenly arranged on the base 100 to ensure the stability of the operating equipment;

[0055] The cable reel 510, high-pressure water device 520, spray device 530, and crane 410 are centrally located on the base 100, with the high-pressure water device 520 and spray device 530 positioned between the cable reel 510 and crane 410. This arrangement not only evenly distributes the weight of each component and balances the forces on the base 100, but also prevents cross-interference between pipelines, ensuring a clear and orderly pipeline layout.

[0056] Preferably, guardrails 110 are provided on both sides of the base 100. The operating platform 200 and the guardrails 110 on both sides enclose the magnetic operation unit on the base 100, thereby preventing parts from falling during the switching of placement points and ensuring safety. It is understood that the guardrails 110 are any structural member that can be used to prevent objects from falling, and can be perforated guard plates, mesh panels, grilles, railings, etc.

[0057] Preferably, the base 100 is provided with rollers 120.

[0062] The material storage device 500 is opened, and the remote control robot 310 is remotely controlled to perform operations.

[0063] The operation method of this embodiment mainly involves manual operation with the aid of a hoisting device 400 and remote control of a remote-controlled robot 310 to perform specific operations. It has a high degree of mechanization and automation, fewer processes and auxiliary operations, and high operating efficiency and safety.
