Description

Technical Field

[0001] This utility model relates to the field of marine engineering technology, specifically to an auxiliary support device for corrosion protection construction of offshore jacket structures. Background Technology

[0002] Offshore jacket structures are large spatial steel frame structures welded together from multiple large steel pipes and connecting longitudinal and transverse pipes, with their bases fixed to the seabed by pile foundations. Due to their long-term exposure to the highly corrosive marine environment, efficient anti-corrosion measures must be taken to ensure their structural safety and durability throughout their design lifespan, such as applying high-performance anti-corrosion coatings like thick-film epoxy coatings and glass flake coatings.

[0003] Currently, painting operations are typically carried out at high altitudes over the sea, requiring workers to use ropes for these tasks. In construction areas near the sea, the effects of tides are significant, posing a high risk of drowning to workers due to rising tides. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide an auxiliary support device for corrosion protection construction of offshore jacket structures, in order to solve the problem that in the prior art, painting operations are usually carried out at high altitudes in the sea area, and construction workers need to use ropes to carry out high-altitude operations. In construction areas close to the sea surface, the impact of tides is significant, and workers face a high risk of drowning due to rising tides.

[0005] This utility model is achieved through the following technical solution: An auxiliary support device for corrosion protection construction of offshore jacket structures includes a sling fixedly connected at one end to the jacket structure, a support plate fixedly connected at the end of the sling away from the jacket structure, and a float fixedly connected to the bottom of the support plate.

[0006] Furthermore, a fence is fixedly connected to the support plate.

[0007] Furthermore, a connecting ring is fixedly connected to the end of the suspension rope away from the guide frame, and multiple pull ropes are fixedly connected to the fence, with the ends of the multiple pull ropes away from the fence all fixedly connected to the connecting ring.

[0008] Furthermore, multiple anti-collision rings are fixedly connected to the side wall of the fence, and the multiple anti-collision rings are arranged at intervals along the circumference of the fence.

[0009] Furthermore, a safety rope is provided on the fence, with one end of the safety rope fixedly connected to the fence and the other end of the safety rope away from the fence fixed to the support column of the guide frame.

[0010] Furthermore, a hook is fixedly connected to the end of the suspension rope away from the support plate.

[0011] Furthermore, there are multiple floats, which are evenly distributed at the bottom of the support plate.

[0012] Furthermore, all of the aforementioned floats are cylindrical in shape.

[0013] The beneficial effects of this utility model are as follows: This auxiliary support device for corrosion protection construction of offshore jacket structures uses a hoisting rope and safety rope fixed to a designated position on the jacket structure (such as a leg or climbing pole). Workers can then move from the jacket structure to a support plate for painting operations. When the tide rises and reaches the bottom of the support plate, the buoyancy of a float keeps the plate afloat, reducing the risk of drowning for workers. Compared to existing technologies, by fixing a float to the bottom of the support plate, it can cope with tidal changes during construction near the sea surface, further reducing the risk of drowning for workers.

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0021] Furthermore, terms such as "identical" do not imply that components must be absolutely identical; minor differences are permissible.

[0022] Please see Figure 1-2 This utility model provides a technical solution: an auxiliary support device for corrosion protection construction of offshore jacket structures, including a sling 1 with one end fixedly connected to the jacket structure, a support plate 2 fixedly connected to the end of the sling 1 away from the jacket structure, and a float 3 fixedly connected to the bottom of the support plate 2.

[0023] A fence 4 is fixedly connected to the support plate 2.

[0024] The end of the suspension rope 1 away from the guide frame is fixedly connected to a connecting ring 5. Multiple pull ropes 6 are fixedly connected to the fence 4, and the ends of the multiple pull ropes 6 away from the fence 4 are all fixedly connected to the connecting ring 5.

[0025] A safety rope 8 is provided on the fence 4. One end of the safety rope 8 is fixedly connected to the fence 4, and the other end of the safety rope 8 away from the fence 4 is fixed to the guide frame leg column.

[0026] The float 3 is made of closed-cell foam material (such as polyethylene foam), which can maintain sufficient buoyancy even if it is slightly damaged.

[0027] The hoisting rope 1, the pull rope 6, and the safety rope 8 are all made of high-strength materials that are resistant to seawater corrosion (such as polyethylene, nylon-coated steel wire rope, etc.), which have a certain degree of durability and reliability in harsh marine environments.

[0028] Working principle: By fixing the fence 4 to the support plate 2, a safety guardrail is formed, reducing the risk of construction workers falling off the support plate 2 during the painting operation.

[0029] By fixing one end of the suspension rope 1 to the guide frame and the other end to the fence 4 and the support plate 2 through the connecting ring 5 and multiple pull ropes 6, the support plate 2 can provide a relatively stable support surface for construction workers.

[0030] As the tide rises, seawater gradually reaches the bottom of the support plate, at which point the float 3 begins to provide buoyancy. As the tide level rises, the buoyancy lifts the support plate 2 and the railing 4, allowing the float 3, support plate 2, railing 4, and construction workers to rise synchronously with the sea surface. The hoisting rope 1 then becomes slack, reducing the risk of drowning for construction workers during painting operations in the construction area near the sea.

[0031] One end of the safety rope 8 is fixed to the railing 4, and the other end is fixed to the guide frame leg. When the float 3 is not in contact with the sea surface, the safety rope 8, the guide frame leg, and the hoisting rope form a triangle, which improves the stability of the support plate 2, reduces the amplitude of the swaying between the support plate 2 and the railing 4, and reduces the probability of construction workers falling off the support plate 2.

[0032] Instructions for use: Before construction, fix the hoisting rope 1 and safety rope 8 to the designated position of the guide frame (such as the guide frame leg column or guide frame climbing pole), and the construction personnel move from the guide frame to the support plate 2 to carry out the painting operation.

[0033] When the tide rises and reaches the bottom of the support plate 2, the support plate 2 floats on the sea surface under the buoyancy of the float 3, reducing the risk of drowning for construction workers.

[0034] Technical benefits: Compared with existing technologies, by fixing the float 3 to the bottom of the support plate 2, it is possible to cope with tidal changes when constructing in areas close to the sea surface, reducing the risk of drowning for construction workers.

[0035] In this embodiment: a plurality of anti-collision rings 7 are fixedly connected to the side wall of the fence 4, and the plurality of anti-collision rings 7 are arranged at intervals along the circumference of the fence 4.

[0036] Technical effect: By fixing multiple anti-collision rings 7 to the side wall of the fence 4, the anti-collision rings 7 can buffer the impact force when the support plate 2 or fence 4 collides with the guide frame structure due to weather conditions such as sea breeze during the painting operation.

[0037] In this embodiment, a hook 9 is fixedly connected to the end of the suspension rope 1 away from the support plate 2.

[0038] Technical benefits: By fixing a hook 9 to the end of the suspension rope 1 away from the support plate 2, it is possible to quickly fix and remove the suspension rope 1 on complex guide frame structures, thus improving construction efficiency.

[0039] In this embodiment, there are multiple floats 3, which are evenly distributed at the bottom of the support plate 2.

[0040] All of the aforementioned floats 3 are cylindrical.

[0041] Technical effect: By evenly distributing multiple floats 3 on the bottom of the support plate 2, the multiple floats 3 provide balanced buoyancy when in contact with the sea surface, and the cylindrical floats 3 have low water flow resistance, which helps the support plate 2 float more stably at sea.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
