Description

Technical Field

[0001] The invention relates to the field of wind turbine blade transportation, and in particular to a multi-layer transportation tooling for wind turbine blade shipping. Background Art

[0002] With the depletion of fossil energy and severe climate change, the use of renewable energy for power generation has become a new trend. As a renewable and clean energy with little environmental impact, wind energy has attracted attention from all countries, and the transformation and development of large-scale wind power generation has become an inevitable trend.

[0003] Large offshore power plants are a new market industry with little experience. As offshore wind power projects are farther and farther from shore, the cost of transporting large wind turbine blades to the construction site is getting higher and higher. The existing transportation method is to fix a wind turbine blade in a tooling to ensure that the blade will not be damaged, and then use a transport vehicle or transport ship to transport the blade to the construction site.

[0004] When the above method is adopted, one tool can only fix one wind turbine blade, and the blade is laid flat during transportation, so multiple transport tools and transport ships are required for multiple round trips, which increases the transportation cost of the blades and reduces the construction progress. Summary of the invention

[0030] The following is combined with Figure 1-2 This application is described in further detail.

[0031] The present application embodiment discloses a multi-layer transport tooling for wind turbine blades. Figure 1 A wind turbine blade shipping multi-layer transport tooling includes a blade root transport tooling and a blade tip transport tooling, wherein the blade root transport tooling is arranged at the blade root of the blade 1, and the blade tip transport tooling is arranged in the middle of the blade 1. The blade root transport tooling and the blade tip transport tooling are used to fix both ends of the blade 1 at the same time, so that the blade 1 is kept in a stable lifting state.

[0032] Both the blade root transport tooling and the blade tip transport tooling include an upper fixing part 2 and a lower fixing part 21, which are arranged vertically and are used to fix a blade 1 respectively, thereby realizing the simultaneous transmission of double-layer blades 1. In this way, double-layer blades 1 can be transported simultaneously during transportation, reducing transportation costs and facilitating the improvement of construction progress.

[0033] The upper fixing part 2 and the lower fixing part 21 are both arranged as rectangular frame structures, and both the upper fixing part 2 and the lower fixing part 21 include a top seat 3, a base 31 and a longitudinal rod 4, and both ends of the longitudinal rod 4 are respectively connected to the top seat 3 and the base 31, and both the upper fixing part 2 and the lower fixing part 21 are provided with a clamp 5, and the clamp 5 is used to fix the blade 1. The base 31 of the upper fixing part 2 and the base 31 of the lower fixing part 21 are connected by a fixing pin 32, so as to realize a detachable connection between the upper fixing part 2 and the lower fixing part 21.

[0034] Reference Figure 1 and Figure 2 The clamp 5 includes two U-shaped slots 51, which are arranged opposite to each other, so as to form a space between the two U-shaped slots 51, in which the blade 1 is placed, and a tooling bolt is provided to fix the blade 1 and the U-shaped slot 51. The two U-shaped slots 51 are connected to the base 31 and the top seat 3 respectively, and the two U-shaped slots 51 are connected by a locking bolt 52 on the sides close to each other. The locking bolt 52 realizes the detachable connection of the two U-shaped slots 51, which is convenient for fixing and removing the blade 1.

[0035] A support rod is connected between the longitudinal rods 4 of the upper fixing part 2 and the lower fixing part 21. The longitudinal rod 4 is divided into an upper branch rod 41 and a lower branch rod 42. The ends of the upper branch rod 41 and the lower branch rod 42 that are close to each other are connected with a connecting plate 43. The two connecting plates 43 are connected by a fixing bolt 44, so that the upper branch rod 41 and the lower branch rod 42 can be detachably connected. In the embodiment of the present application, the upper branch rod 41 and the lower branch rod 42, the two U-shaped slots 51, the upper fixing part 2 and the lower fixing part 21 are all detachable. When the fan blade 1 needs to be placed in the tooling, the fan blade 1 can be placed in one U-shaped slot 51, and then fixed by using the other U-shaped slot 51, and the locking bolt 52 and the fixing bolt 44 are sequentially tightened to achieve the placement of the double-layer blade 1.

[0036] The length of the large wind turbine blade 1 is up to 112m. The lifting points of the blade 1 have been reinforced. Support points are set on the blade 1, and the distance between the support points is 58m. In order to enhance the stability of the blade 1 and avoid the wear of the blade 1 by the U-shaped slot 51, rubber sheets are filled in the blade 1 and the U-shaped slot 51. There should be no connection points between the transport tooling and the blade 1, and all gaps are filled with rubber sheets. The rubber sheet can adapt to blades 1 of different diameters. The diameters of blades 1 of different models are different. When a blade 1 with a small diameter is hoisted, the rubber sheet needs to be thickened to make the blade 1 fit the rubber sheet. When a blade 1 with a large diameter is hoisted, the rubber sheet is thinner to leave enough space for the blade 1 to be placed in the transport tooling.

[0037] In order to enhance the stability of the blade 1 during transportation and reduce the shaking and tilting of the blade 1, the longitudinal rod 4 is provided with a pull ring 61, and the pull ring 61 is connected to a diagonal chain 6. The other end of the diagonal chain 6 away from the pull ring 61 is connected to the transport ship, thereby tightening the blade 1.

[0038] In the embodiment of the present application, reinforcing rods 7 are provided between the longitudinal rod 4 and the top seat 3 and the base 31 , and the reinforcing rods 7 are used to enhance the connection strength of the transport tooling.

[0039] In the embodiment of the present application, the top seat 3 of the upper fixing portion 2 is provided with a lifting ring 8, and the lifting ring 8 is used to be connected with a lifting rope, so as to facilitate lifting the blade 1 by using the lifting rope.

[0040] In the embodiment of the present application, the top seat 3 , the reinforcing rod 7 and the upper branch rod 41 are commonly connected to a working platform 9 , and the working platform 9 facilitates construction workers to perform construction work on the blade 1 .

[0041] The implementation principle of a multi-layer transport tooling for wind turbine blades shipped by ship in the embodiment of the present application is as follows:

[0042] 1. Put the double-layer blade 1 into the transport tooling, fix the blade 1 with the clamp 5, connect the two U-shaped slots 51 with the locking bolt 52, connect the upper branch rod 41 and the lower branch rod 42 with the fixing bolt 44, and connect the upper fixing part 2 and the lower fixing part 21 with the fixing pin 32;

[0043] 2. The two sides of the transport tooling are locked with steel chains to prevent the blade 1 from shaking and tilting during transportation;

[0044] 3. After the transport ship is transported to the construction site and positioned, the blade root transport tooling only needs to remove the inclined chain 6, and the blade tip transport tooling needs to remove the upper half of the U-shaped groove tooling. After removing the inclined chain 6, the blade 1 can be reversed and hoisted for construction.

[0045] This specific implementation manner is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make non-creative modifications to the specific implementation manner as needed, but such modifications are protected by the patent law as long as they are within the scope of the claims of the present application.
