[0025] Referring to Figure 1 , the present utility model provides a blade support, which includes a top plate 1 and two vertical frames 2. The two vertical frames 2 are arranged in parallel. The two ends of the top plate 1 are respectively connected to the upper ends of the two vertical frames 2. The space below the top plate 1 and between the two vertical frames 2 is the lower space, and the space above the top plate 1 is the upper space. The cross-sectional area of the lower space is larger than the maximum cross-sectional area of the blade. The blade support of the present application is mainly used for the transportation of large blades, especially suitable for the double-layer offshore transportation of large offshore wind turbine blades. Referring to Figure 4 , in use, first place a blade 9 on the ship deck, then place two blade supports in parallel on the ship deck and make the blade 9 pass through the lower space. One blade support is placed at the root of the blade 9, and the other blade support is placed in the middle of the blade 9. Subsequently, place a blade 9 on the top plates 1 of the two blade supports on the ship deck, that is, place it in the upper space. The top plates 1 of the two blade supports respectively support the root and the middle of the blade 9, realizing the double-layer offshore transportation of large blades. The blade support can ensure the loading capacity and, compared with a container, can reduce the occupation of the ship's space.
[0026] Preferably, guardrails 3 that can be telescopically extended and retracted vertically are provided around the top plate 1. The guardrails 3 play a role in ensuring the safety of operators and preventing them from falling off the edge of the top plate 1 when operating on the top plate 1. Since the height of the hook of the current ship crane is not high, the guardrails 3 are set to be telescopically extendable and retractable. When the guardrails 3 are lowered, the requirement for the hook height during the hoisting of the upper wind turbine blades can be reduced, meeting the use of the existing ship crane to hoist the upper wind turbine blades without the need to use a floating crane for hoisting, thus avoiding interfering with the hoisting of the upper wind turbine blades by the ship crane.
[0027] Specifically, referring to Figure 2 , the guardrail 3 includes a C-shaped railing 31, two sliding sleeves 32, and a bolt 33. The two sliding sleeves 32 are arranged at the edge of the top plate 1. The two vertical sections 311 of the railing 31 slide in the two sliding sleeves 32 respectively. Through holes 312 are provided at the upper and lower ends of the vertical sections 311 of the railing 31, and insertion holes 321 are provided on the sliding sleeves 32. The bolt 33 is inserted into the insertion holes 321 and the through holes 312 to fix the position of the railing 31 relative to the sliding sleeves 32. Referring to Figure 3 , when hoisting the upper wind turbine blades, first pull out the bolt 33, then push the vertical sections 311 of the railing 31 downward along the sliding sleeves 32 until the through holes 312 at the upper ends of the vertical sections 311 are aligned with the insertion holes 321 of the sliding sleeves 32, and finally insert the bolt 33 into the through holes 312 at the upper ends of the vertical sections 311 and the insertion holes; referring to Figure 1 , when it is necessary to use the guardrail 3, first pull out the bolt 33, then pull the vertical sections 311 of the railing 31 upward along the sliding sleeves 32 until the through holes 312 at the lower ends of the vertical sections 311 are aligned with the insertion holes 321 of the sliding sleeves 32, and finally insert the bolt 33 into the through holes 312 at the lower ends of the vertical sections 311 and the insertion holes.
[0028] Preferably, a protective rod 34 is horizontally arranged inside the railing 31. The protective rod 34 can prevent the gap inside the C-shaped railing 31 from being too large and play a protective role. Through grooves 322 penetrating the upper and lower ends are formed on the opposite sides of the two sliding sleeves 32. The through grooves 322 communicate with the inner cavities of the sliding sleeves 32. When the vertical sections 311 of the railing 31 slide in the sliding sleeves 32, the ends of the protective rod 34 can slide along the through grooves 322. The through grooves 322 are provided to ensure that the vertical sections 311 of the guardrail 3 are not interfered by the protective rod 34 when sliding in the sliding sleeves 32.
[0029] Preferably, a ladder 4 is provided inside the vertical frame 2. The upper end of the ladder 4 extends to the top of the vertical frame 2, and the lower end of the ladder 4 extends to the bottom of the vertical frame 2. The ladder 4 is provided to facilitate the operator to climb onto the top plate 1.
[0030] Preferably, a toolbox is recessed on the top plate 1 for storing tools such as chains, ropes, clamping plates, and straps. Further, a cover plate 5 is hinged on the top plate 1, and the cover plate 5 can cover the toolbox. Usually, the cover plate 5 covers the toolbox. When the operator needs to take or place tools from the toolbox, the cover plate 5 can be opened upward. At Figure 1In the figure, the toolbox is covered by the cover plate 5, so the toolbox cannot be seen in the figure.
[0031] Preferably, a lashing ring 6 is provided on the top surface of the vertical frame 2 to facilitate the use of a lashing rope. Here, the lashing rope is used to fix the wind blade 9 on the top surface of the vertical frame 2. Secondly, a lashing ring 6 can also be provided on the outer side surface of the vertical frame 2 to facilitate the use of a lashing rope. Here, the lashing rope is used to fix the wind blade support on the ship deck. The number of lashing rings 6 is set according to needs.
[0032] Preferably, a reinforcing rib 7 is provided between the vertical frame 2 and the top plate 1. By providing the reinforcing rib 7, the connection strength between the vertical frame 2 and the top plate 1 can be enhanced, thereby improving the strength and stability of the entire wind blade support.
[0033] Preferably, corner fittings 8 are provided at the four corners of the vertical frame 2. When the wind blade support is idle, more than two wind blade supports can be stacked vertically. The corner fittings of the upper and lower wind blade supports are locked by a twist lock. Among them, the bottom corner fitting 8 of the vertical frame 2 of the upper wind blade support and the top corner fitting 8 of the vertical frame 2 of the corresponding lower wind blade support are locked by a twist lock to achieve the fixation between the upper and lower wind blade supports. In addition, the setting of the corner fittings 8 also facilitates the hoisting of the wind blade support and provides a lifting position for the wind blade support.
[0034] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
