Problems solved by technology
Because the barge will shake on the sea, it will bring certain difficulties to the painting operation, and there are also potential safety hazards for the construction personnel
[0005] The second is to build scaffolding. This method is time-consuming and laborious. Usually, it takes 100 people and 14 days to complete the construction of scaffolding. The steel used is close to 500 tons. Labor costs, in-factory transportation costs and management costs add up. About 500,000 RMB
After the painting operation is completed, it will cost another 500,000 RMB to dismantle and transport to the designated location

Embodiment Construction
[0027] Typical embodiments embodying the features and advantages of the present invention will be described in detail in the following description. It should be understood that the invention is capable of various changes in different embodiments without departing from the scope of the invention, and that the description and illustrations therein are illustrative in nature and not limiting. this invention.
[0028] An embodiment of the present invention provides a suspension operation device, which can be movably suspended under the ferromagnetic bottom surface of a platform. The platform can be a building or an offshore platform, such as the offshore semi-submersible platform in the embodiment. These platforms Has a ferromagnetic bottom surface that requires work.
[0029] In the embodiment, the operating device at least includes an operating carrier and a suction and lifting mechanism. The operating carrier is used to carry construction personnel, and at least one lifting po...

The invention provides a suspension operation apparatus and an operation method. The suspension operation apparatus can movably suspend beneath a ferromagnetic undersurface of a platform. The operation apparatus comprises an operation carrier and a suction hanging mechanism. The operation carrier is provided with at least a lifting point so as to lift the operation carrier. The suction hanging mechanism can be connected between the lifting point and the ferromagnetic undersurface. A lifting point is connected with at least two lifting mechanisms. The suction hanging mechanism comprises a connection part and a permanent magnet suction hanging device. The permanent magnet suction hanging device can be adsorbed on the ferromagnetic undersurface. The connection part is connected between the permanent magnet suction hanging device and the lifting point. The operation carrier can be directly suspended beneath the permanent magnet suction hanging device through the suction hanging mechanism. By the utilization of the permanent magnet suction hanging device which can be turned on and turned off, stepping translation of the suction hanging mechanism can be realized on the precondition of guaranteeing safe suction hanging. The whole structure is simple. The suspension operation apparatus has advantages of low overall cost, short construction preparation period and low labor cost.
Description
technical field [0001] The invention relates to a high-altitude operation device, especially a high-altitude suspension operation device and an operation method suitable for operation at the bottom of a semi-submersible platform deck box. Background technique [0002] After the deck box of the semi-submersible platform is launched, due to slideways, push eye panels and other internal constructions, local sandblasting and painting operations are still required. The operation at the bottom of the deck box of the semi-submersible platform belongs to high-altitude operations. Since it is more than 30 meters above the ground when it is in the dock and close to 25 meters from the sea level when it is in the dock, the construction difficulty and risk factor are very high. [0003] When workers are working on the bottom of the deck box, the following two working methods are usually used in the prior art: [0004] The first is to rent an aerial work vehicle at the dock. Due to the h...
