Description

Technical Field

[0001] This utility model belongs to the field of steel pile coating technology, and specifically relates to a retractable and foldable single pile paint repair platform. Background Technology

[0002] With the increasing global demand for renewable energy, the offshore wind power industry is developing rapidly. As the main supporting structure of offshore wind turbines, monopile foundations are exposed to harsh marine corrosion environments for extended periods, including seawater immersion, wave impact, and salt spray erosion. Therefore, the integrity of their surface anti-corrosion coating (i.e., topcoat) is extremely important. Large cylindrical structures such as offshore wind turbine monopiles and dock foundations require immediate repair, inspection, and overlap treatment after topcoat application. However, due to the enormous size of monopiles (diameters ranging from several meters to tens of meters, and lengths of tens of meters), the complex on-site environment (wind, humidity, and temperature variations), and the inherent characteristics of the spraying operation, paint film defects such as runs, orange peel, missed areas, and dry spray drips are unavoidable, as well as spray overlap marks that require treatment. These defects must be repaired, inspected, and treated promptly after topcoat application; otherwise, permanent quality hazards will remain, seriously affecting the integrity of the anti-corrosion layer and its design life.

[0003] Currently, there are the following problems in building foldable and retractable work platforms: 1. Requires significant material and labor costs: Erecting a scaffolding platform requires a large amount of scaffolding materials and is time-consuming and labor-intensive.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The embodiments of this utility model will now be described based on its overall structure.

[0031] like Figures 1-7 As shown, this embodiment provides a retractable and foldable monopile paint repair platform, comprising: Support column 1, the number of support columns 1 is at least two, at least two support columns 1 are used to fix to the wall or to the ground, and two adjacent support columns 1 are distributed at intervals on the same vertical plane; Movable column 2, the number of movable columns 2 is at least two, the movable columns 2 correspond one-to-one with the support columns 1, the movable columns 2 and the support columns 1 are connected by hinge 9, the movable columns 2 can be stacked close to the support columns 1 or far away from the support columns 1; For example, there are two supporting columns 1 and two movable columns 2. The two supporting columns 1 and two movable columns 2 are arranged in a rectangular shape. When the two movable columns 2 retract, the two movable columns 2 swing upward and stack on the sides of the two supporting columns 1. Support tube 5, each movable column 2 is hinged to a support tube 5, and the other end of the support tube 5 is connected to one end of a hoisting mechanism 3; Each movable column 2 is connected to a hoisting mechanism 3; Platform plate 4 is fixed on all support tubes 5. For example, when there are two support tubes 5, two corners of the platform plate are fixedly connected with connecting ear plates 17. The connecting ear plates 17 are connected and fixed to the support tubes through connecting bolts 20. When the platform panel is retracted and folded, the support tube is pulled by the suspension mechanism, causing the support tube to rotate upward, which in turn drives the platform panel to rotate. The support tube and the platform panel are then stacked on the side of the movable column. A ladder is installed on one side of the supporting column 1; by installing a ladder, it is convenient for workers to climb to the corresponding height, open the platform plate, and then walk on the platform plate to repair the single pile. Among them, the structure formed by the connection of the support pipe 5, the hoisting mechanism 3, and the platform plate 4 is a local platform. There are multiple local platforms, which are distributed at intervals on the movable column 2. For example... Figure 1As shown, since the monopile is a cylinder, its bottom and top are relatively far from the movable column. Therefore, the platform plate needs to be extended to a position close to the top and bottom of the monopile for repair. The middle position of the monopile is closest to the movable column, so the platform plate does not need to be extended much to repair the monopile. The hoisting mechanism pulls the end of the support pipe 5 away from the movable column 2 to ensure that the support pipe and the platform plate are kept horizontal, making it convenient for repair workers to work on the platform plate.

[0032] The supporting column 1, movable column 2, and supporting pipe 5 are all existing steel pipes used in scaffolding, which will not be elaborated upon here. The platform plate 4 is set according to the distance between the single pile 6 and the movable column 2. For positions with a greater distance, the length of the supporting pipe 5 and the size of the platform plate 4 are adaptively lengthened and enlarged, while for positions with a closer distance, the length of the supporting pipe 5 and the size of the platform plate 4 are adaptively shortened and reduced, thereby enabling repairs at different locations. In this embodiment, the repair platform, through the setting of the supporting pipe 5 and the hoisting mechanism 3, reduces the amount of erection materials compared to existing scaffolding which requires several reinforcing columns for support and stability. The setting of the hinge 9 and the hoisting mechanism 3 facilitates the construction of the entire repair platform. The welding of the columns is completed before construction, reducing the steps of building the platform layer by layer, thereby reducing construction time. It also reduces the safety hazards caused by workers building at heights.

[0033] Because the movable column 2 can move relative to the supporting column 1, it can accommodate the inspection and repair of the complete outer surface of the single pile 6, as well as the inspection and repair of the paint on single piles 6 of different diameters, thus solving the problem of needing to configure scaffold crossbars of different lengths. At the same time, by folding the movable column 2, the supporting pipe 5, and the platform plate 4, the need to dismantle the platform after use is avoided, and the potential hazards caused by dismantling are reduced.

[0034] Multiple hinges 9 connect the movable column 2 and the supporting column 1, and these hinges 9 are spaced apart between the movable column 2 and the supporting column 1. This arrangement improves the stability between the movable column 2 and the supporting column 1.

[0035] The hinge 9 includes a first hinge seat 21, a hinge rod 18, a second hinge seat 19, a first connecting bolt, and a second connecting bolt. The first hinge seat 21 and the second hinge seat 19 are respectively fixed to the movable column 2 and the supporting column 1. The first hinge seat has two first hinge ears, each with a first through hole. The second hinge seat has two second hinge ears, each with a second through hole. The hinge rod 18 has a first connecting through hole and a second connecting through hole at both ends. The first connecting bolt passes through the first through hole and the first connecting through hole, and the second connecting bolt passes through the second through hole and the second connecting through hole, respectively. The first connecting bolt and the second connecting bolt are rotatably connected to the first connecting through hole and the second connecting through hole, respectively. Both the first connecting bolt and the second connecting bolt are connected with nuts. Specifically, the first connecting bolt passes through the first through holes of the two first hinge ears and the first connecting through hole of the hinge rod, and the second connecting bolt passes through the second through holes of the two second hinge ears and the second connecting through hole of the hinge rod.

[0036] Specifically, the first and second connecting bolts can also be replaced with other rods, simply by setting corresponding arc-shaped rings at both ends of the rods to prevent them from detaching.

[0037] The support tube 5 is hinged to the movable column 2 through the third hinge seat. The third hinge seat is provided with a third hinge ear and a third through hole. The support tube 5 is provided with a third connecting through hole. The third through hole and the third connecting through hole are connected by a third connecting bolt. The third connecting bolt is connected with a nut and is rotatably connected to the third through hole.

[0038] The lifting mechanism 3 includes a first buckle, a second buckle, and a chain. The first buckle is fixed to the movable column 2, and the second buckle is fixed to the platform plate 4 or the support tube 5. The two ends of the chain are connected to the first buckle and the second buckle, respectively. The first buckle and the second buckle are existing buckles, and the chain is an existing iron chain. It is sufficient to purchase existing products with sufficient strength, which will not be elaborated on here.

[0039] The retractable and foldable monopile paint repair platform also includes a pulley translation mechanism 7, which includes a slide rail 8, a sliding component and a hook 15. The slide rail 8 is fixed above the support column 1, the sliding component is slidably connected to the slide rail 8, and the hook 15 is set at the bottom of the sliding component.

[0040] The sliding assembly includes a connecting frame, with rotating shafts 12 connected to both sides of the top of the connecting frame. Each rotating shaft 12 is rotatably connected to a roller 11 via a bearing. Both rollers 11 are rotatably connected to a slide rail 8. A hook 15 is fixed to the bottom of the connecting frame.

[0041] The connecting frame includes a horizontal plate 14 and two vertical plates 13, which are fixed to both ends of the horizontal plate 14. Two rotating shafts 12 are fixedly connected to the two vertical plates 13, and a hook 15 is fixedly connected to the horizontal plate 14. Specifically, the horizontal plate 14 and the two vertical plates 13 form a U-shape. The slide rail 8 is an I-beam. The two rotating shafts 12 extend from the two vertical plates 13 into the waist of the I-beam. To prevent the roller 11 from detaching from the I-beam, the two rotating shafts 12 extend as far as possible into the waist of the I-beam, with the connection between the roller 11 and the rotating shaft 12 close to the waist of the I-beam. Alternatively, limiting vertical plates 1613 are set on both sides of the bottom plate of the I-beam to prevent the roller 11 from detaching from the sides of the I-beam, ensuring safety. The hook 15 can pass through from the bottom to the top of the horizontal plate 14. The part that passes through can be fixed by a nut threaded connection, or a locking pin can pass through the hook 15 to prevent it from detaching. The connection part between the hook 15 and the safety rope can be a bent hook structure or a ring structure.

[0042] By setting up the pulley translation mechanism 7 in this way, it is convenient for repair workers to hang safety ropes.

[0043] The foregoing description of specific exemplary embodiments of the present invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the present invention to the precise forms disclosed, and it is obvious that many changes and variations can be made based on the above teachings. Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not intended to limit the invention.
