[0001] This utility model relates to the field of transportation tooling technology, specifically a vertical transportation tooling for offshore wind turbine towers. Background Technology

[0002] With the continuous growth of global demand for clean energy, the offshore wind power industry has ushered in a period of rapid development. As a key supporting structure for wind turbine generators, the size and weight of wind turbine towers are also increasing with the increase of wind turbine power. Foreign countries have relatively mature technologies for vertical transportation of offshore wind turbine towers. These technologies have the following characteristics: high transportation efficiency, reducing transportation time and costs; and good transportation safety, reducing the risk of tower damage during transportation.

[0003] The domestic offshore wind power market is in a stage of rapid development, but the tower transportation technology is relatively backward, mainly relying on traditional horizontal transportation methods, which have problems such as low transportation efficiency and insufficient safety. Therefore, a vertical transportation tool for offshore wind power towers is proposed to address the above problems. Summary of the Invention

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A vertical transport fixture for offshore wind turbine towers includes a tower body and a fixed base frame located at the bottom of the tower body. Multiple fixing plates are fixedly connected to the top edge of the fixed base frame. Fixing ropes are fixedly connected to the outer sides of the fixing plates. Multiple rubber plates are fixedly connected to the top of the fixed base frame on one side of each fixing plate. An mounting frame is fixedly connected to the center of the top of the fixed base frame on one side of each rubber plate. An inner cylinder is fixedly connected to the outer side of the mounting frame. A positioning cylinder is fixedly connected to the top of the mounting frame. A vertically positioned positioning rod is inserted into the inner side of the positioning cylinder. A top cover is fixedly connected to the top of the positioning rod. Symmetrically arranged lifting rings are fixedly connected to the top of the top cover. Multiple mounting plates are fixedly connected to the bottom edge of the top cover. A clamping assembly is provided on the outer side of the tower body.

[0007] Preferably, the end of the fixing rope away from the fixing hole plate is fixedly connected to the outside of the mounting hole plate, the bottom end of the tower body is tightly fitted with the top end of the rubber plate, and the outside of the inner cylinder is tightly fitted with the inside of the tower body.

[0008] Preferably, the clamping assembly includes a clamping frame that is snapped into the inner side of the fixed base frame, a threaded cylinder is fixedly connected to the top of the clamping frame, a bolt is threaded into the inner side of the threaded cylinder, and a clamping plate is fixedly connected to one end of the bolt.

[0024] A vertical transport fixture for offshore wind turbine towers includes a tower body 1 and a fixed base frame 2 located at the bottom of the tower body 1. Multiple fixing plates 3 are fixedly connected to the top edge of the fixed base frame 2. Fixing ropes 4 are fixedly connected to the outer sides of the fixing plates 3. Multiple rubber plates 5 are fixedly connected to the top of the fixed base frame 2 on one side of the fixing plates 3. An mounting frame 6 is fixedly connected to the center of the top of the fixed base frame 2 on one side of the rubber plates 5. An inner cylinder 7 is fixedly connected to the outer side of the mounting frame 6. A positioning cylinder 8 is fixedly connected to the top of the mounting frame 6. A vertically arranged positioning rod 9 is inserted into the inner side of the positioning cylinder 8. A top cover 10 is fixedly connected to the top of the positioning rod 9. Symmetrically arranged lifting rings 11 are fixedly connected to the top of the top cover 10. Multiple mounting plates 12 are fixedly connected to the bottom edge of the top cover 10. A pressure plate is provided on the outer side of the tower body 1. The fastening assembly 13 and the fixing rope 4 are fixedly connected to the outside of the mounting plate 12 at one end away from the fixing hole plate 3. The bottom end of the tower body 1 is tightly fitted with the top end of the rubber plate 5, and the outside of the inner cylinder 7 is tightly fitted with the inside of the tower body 1. Through the setting of the fixing hole plate 3, fixing rope 4, rubber plate 5, mounting frame 6, inner cylinder 7, positioning cylinder 8, positioning rod 9, top cover 10, lifting ring 11 and mounting hole plate 12, the tower body 1 is hoisted to the top of the fixed base frame 2 when installing the tower body 1, and the top cover 10 and fixing rope 4 are used to fix the tower body 1. This design occupies less space than horizontal transportation, improves transportation efficiency, and provides more comprehensive restriction of the tower body 1, effectively reducing the damage to the tower body 1 during transportation and preventing the tower body 1 from rolling and causing safety accidents.

[0025] The clamping assembly 13 includes a clamping frame 131 that engages with the inner side of the fixed base frame 2. A threaded cylinder 132 is fixedly connected to the top of the clamping frame 131, and a bolt 133 is threadedly connected to the inner side of the threaded cylinder 132. A clamping plate 134 is fixedly connected to one end of the bolt 133. There are multiple clamping assemblies 13, which are distributed along a polar axis on the outer side of the tower body 1. The clamping plate 134 is horizontally aligned with the inner cylinder 7, and the side of the clamping plate 134 closest to the tower body 1 is tightly fitted to the outer side of the tower body 1. The clamping assembly 13, clamping frame 132, and bolt 133 are fixedly connected to the inner side of the tower body 1. After the tower body 1 is fixed, the clamping assembly 13 is installed, consisting of frame 131, threaded cylinder 132, bolt 133, and clamping plate 134. The frame 131 is inserted into the fixed base frame 2, and then the bolt 133 is rotated until the side of the clamping plate 134 closest to the tower body 1 is tightly fitted with the tower body 1. Since the inner cylinder 7 is horizontally aligned with the clamping plate 134, the inner cylinder 7 and the clamping plate 134 can jointly fix the tower body 1. This design can further fix the tower body 1 and increase the stability of the tower body 1.

[0026] Workflow: When installing the tower body 1, first, fix the fixed base frame 2 to the ship using a support plate. Hoist the tower body 1 and place it on top of the fixed base frame 2, ensuring the inner side of the fixed base frame 2 is tightly fitted against the outer side of the inner cylinder 7 on the mounting frame 6, and the top of the rubber plate 5 is tightly fitted against the bottom of the tower body 1. Then, hoist the lifting ring 11 on the top cover 10, inserting the positioning rod 9 on the top cover 10 into the positioning cylinder 8 on the mounting frame 6. Next, fix one end of the fixing rope 4 to the outer side of the fixing hole plate 3 on the fixed base frame 2, and pass the other end of the fixing rope 4 through the mounting hole plate 12 at the bottom of the top cover 10. Tighten and secure the fixing rope 4 to complete the installation of the tower body 1. During the transportation of the tower body 1, the fixing rope 4 and the positioning rod 9 can vertically lock the tower body 1, preventing it from moving up and down due to bumps. The inner cylinder 7 can limit the horizontal movement of the tower body 1, preventing... The tower body 1 can be moved horizontally without the need for horizontal transport. This design takes up less space than horizontal transport, improves transport efficiency, and provides more comprehensive restraint on the tower body 1, effectively reducing damage to the tower body 1 during transport and preventing safety accidents caused by the tower body 1 rolling. The next step is to install the clamping assembly 13. The retaining frame 131 at the bottom of the threaded cylinder 132 is inserted into the fixed base frame 2, so that the retaining frame 131 is engaged with the fixed base frame 2. The clamping plate 134 on the bolt 133 is brought close to the tower body 1. Then the bolt 133 is rotated until the side of the clamping plate 134 close to the tower body 1 is tightly fitted with the tower body 1. Since the inner cylinder 7 and the clamping plate 134 are horizontally aligned, the inner cylinder 7 and the clamping plate 134 can jointly fix the tower body 1. The design of the clamping assembly 13 can further fix the tower body 1 and increase the stability of the tower body 1.
