Description

Technical Field

[0001] This invention belongs to the field of offshore wind power engineering technology, specifically relating to a jacket roll-on / roll-off trolley and a jacket roll-on / roll-off method. Background Technology

[0002] Currently, in offshore engineering operations, pre-designed structural components need to be transported onto ships and then to the installation site. Due to their large size, the assembled structural components are difficult to transport. Among them, the wind turbine jacket, as a basic support structure, is generally composed of a spatial truss structure system with four columns. The jacket structure is extremely high and wide, making it inconvenient to install at sea. Therefore, the jacket is installed on land. After the entire structure is assembled and completed on land, it needs to be transported to a barge using special handling equipment, and then transported to the installation site at sea by barge for installation.

[0003] Currently, most large-scale marine transport operations utilize roll-on / roll-off (Ro-Ro) methods. However, existing Ro-Ro equipment suffers from poor stability, limited transport span, and requires constant adjustments, severely impacting transport efficiency.

[0004] Chinese patent application CN202010903906.X discloses a bottom fixture and installation method for the upper component of an offshore wind power booster station. The method includes a support pier and four fixture units, each with a mounting base for the upper component. The four fixture units have four mounting bases, and the upper component has four leg connection nodes. After fixing the four leg connection nodes to the four mounting bases, it is used for installation and transportation, improving installation accuracy and ensuring the integrity and stability of the load-bearing structure. However, the prior art lacks an adjustment structure, making it impossible to guarantee structural stability during roll-on / roll-off installation. When applied to the roll-on / roll-off installation of ultra-high structures, this leads to poor stability, high construction risks, and difficulty in meeting construction requirements. It may even necessitate the use of additional equipment for adjusting and constraining the structure's stability.

[0005] Therefore, it is necessary to propose a jacket support roll-on trolley and a jacket support roll-on method to meet the needs of jacket support construction operations. Summary of the Invention

[0006] The purpose of this invention is to address the aforementioned problems and shortcomings by providing a jacket support roll-on trolley and a jacket support roll-on method, which can solve the problems of poor stability and low handling efficiency in the prior art, thereby ensuring good support stability, stable roll-on movement, low construction operation risk, and good practicality during the jacket support roll-on process.

[0040] ③ The present invention sets the upper platform as a concave structure and the lower platform as a convex structure that cooperates with the upper platform, which can restrict the movement of the upper platform, ensure the stability of the roller trolley movement of the jacket frame, and realize the pitch adjustment of the upper platform while ensuring structural stability, thus ensuring the overall balance of the jacket frame.

In the attached drawings of this embodiment, four sets of trolley units 100 are arranged at the bottom of the jacket support in a matrix. Self-balancing alignment units 400 are arranged between corresponding pairs of trolley units 100 at the front and rear, and between corresponding pairs of trolley units 100 on the left and right sides. The self-balancing alignment units are used to detect the balance between corresponding pairs of trolley units.

The boss 124 and the recess 115 allow the support frame to swing back and forth relative to the module vehicle 120, but prevent the support frame 110 from swinging left and right relative to the module vehicle 120. In this embodiment, "back and forth" is defined by the direction of travel of the walking component, which is the same as the slotting direction of the recess. The walking component 121 can be an existing AGV or a chassis with multiple sets of rubber wheels at the bottom to ensure stable support of the guide frame's weight and achieve stable movement and support.
