[0002] With the strengthening of ecological protection awareness and the compression of wind power project construction costs, single-blade installation will gradually become the mainstream. When using single-blade lifting technology, the blades need to be turned over onto a transport vehicle, and then transported to the construction site by the transport vehicle.

[0003] Due to the limited width of the transport vehicle, existing transport vehicles often increase the load-bearing width by welding Bailey beams to achieve the transportation of blades. However, as the capacity of the unit gradually increases, the height of the unit also gradually increases, and the length of the blades of the unit also gradually increases.

[0034] The features and exemplary embodiments of various aspects of the present application will be described in detail below. In the detailed description below, many specific details are proposed to provide a comprehensive understanding of the present application. However, it is obvious to those skilled in the art that the present application can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present application by illustrating examples of the present application. In the accompanying drawings and the following description, at least some of the known structures and technologies are not shown to avoid unnecessary ambiguity in the present application; and, for clarity, the size of some structures may be exaggerated. In addition, the features, structures or characteristics described below may be combined in one or more embodiments in any suitable manner.

[0035] The directional words appearing in the following description are all directions shown in the figures, and do not limit the fixing tooling and blade transportation method of this application. In the description of this application, it should also be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0036] For existing blades of small-capacity units, the distance between the root and the tip of the blade is relatively short, about 48m. The blades can be placed on a transport vehicle. Even if the width of the transport vehicle is not enough, the single blade lifting of the existing small-capacity unit can be achieved by welding Bailey beams with a length of about 3m on both sides of the transport vehicle. However, as the capacity of the unit gradually increases, the blades gradually grow, and the distance between the root and the tip of the blades of large-capacity units reaches more than 65m, resulting in the need to weld Bailey beams with a length of about 10m on both sides of the transport vehicle to meet the support requirements of the blades. The above solution is difficult to achieve. In addition, when welding Bailey beams on both sides of the transport vehicle, the Bailey beams need to be removed from the transport vehicle after the lifting is completed, which greatly reduces the construction efficiency on site.

[0037] In order to solve the above problems, the present application embodiment provides a method for transporting a fixed tool and a blade. Figures 1 to 7 The fixing tooling and the method for transporting blades according to the embodiment of the present application are described in detail.

[0038] See also Figure 1 and Figure 2 The embodiment of the present application provides a fixing tool 100, which is used to be set on a transport vehicle 200 and support a blade 300. The fixing tool 100 includes a base 1 and a bearing platform 2. The base 1 is set on the transport vehicle 200, and the bearing platform 2 is set on one side of the base 1 in the first direction X and connected to the base 1. The bearing platform 2 can switch between an open state and a retracted state. In the open state, the bearing platform 2 protrudes from the base 1 by a first dimension along the first direction X, and a bearing surface is formed on the bearing platform 2 that at least partially protrudes from the outer edge of the transport vehicle 200. The bearing surface is used to fix the blade 300. In the retracted state, the bearing platform 2 protrudes from the base 1 by a second dimension along the first direction X, and the second dimension is smaller than the first dimension.

[0039] The fixed tool 100 in the embodiment of the present application includes a base 1 and a bearing platform 2, which is fixed on the transport vehicle 200 through the base 1. The bearing platform 2 has an open state and a retracted state. When transporting the blade 300, the bearing platform 2 can be switched to the open state to protrude the bearing platform 2 from the outer edge of the transport vehicle 200, thereby expanding the maximum span of the fixed point of the transport vehicle 200 to meet the support requirements for the blades 300 of large-capacity units and ensure the feasibility of single-blade hoisting. In addition, after the transportation of the blade 300 is completed, that is, when the blade 300 is not hoisted, the bearing platform 2 can be switched to the retracted state to at least partially store the bearing platform 2 in the transport vehicle 200 to reduce the impact on the travel of the transport vehicle 200, so that there is no need to frequently disassemble and assemble the fixed tool 100, which greatly improves the construction efficiency on site.

[0040] When the blade 300 is not hoisted, the carrying platform 2 can be at least partially stored in the transport vehicle 200, which will not affect the safety of the transport vehicle 200. Therefore, the fixing tool 100 can be directly fixed to the transport vehicle 200, for example, it can be directly welded to the transport vehicle 200. Therefore, when the blade 300 needs to be transported, there is no need to reinstall the fixing tool 100, which is simple and efficient to use.

[0041] It should be noted that the second size can be a positive value, or can be zero or a negative value, that is, as long as the carrying platform 2 can be at least partially retracted into the base 1 in the retracted state to reduce the impact on the travel of the transportation vehicle 200.

[0042] See also Figure 1 and Figure 2 In some optional embodiments, the transport vehicle 200 has a support surface for carrying goods and a support wall arranged around the outer edge of the support surface, and the base 1 is arranged on the support surface and / or the support wall. The fixing tool 100 can install the base 1 on the support surface and / or the support wall according to the specific opening method of the carrying platform 2, which can meet the requirement that the carrying platform 2 can extend a preset width relative to the support surface along the first direction X in the opened state.

[0043] It is understandable that the transport vehicle 200 can be selected according to the application environment of the wind turbine. For example, when installing an offshore wind turbine, the transport vehicle 200 can be a ship, and when installing an onshore wind turbine, the transport vehicle 200 can also be a truck, etc., but it is not limited to this.

[0044] Taking the transport tool 200 as an installation ship as an example, the fixed tool 100 can be set on the deck of the installation ship. When the blade 300 needs to be transported, the carrying platform 2 can be switched to the open state, so that the carrying platform 2 extends out of the deck to meet the width requirement of the distance between the root and tip of the blade 300 for the deck of the installation ship, thereby supporting the blade 300 that is barged from the transport ship to the installation ship and ensuring the feasibility of the single-blade lifting method. After the transportation of the blade 300 is completed, the carrying platform 2 can be switched to the retracted state, so that the carrying platform 2 is recovered into the deck to avoid affecting the normal driving of the installation ship, so that there is no need to frequently disassemble and assemble the fixed tool 100, which greatly improves the construction efficiency of the offshore construction site.

[0045] Optionally, the fixing fixture 100 may be arranged only on one side of the transport vehicle 200 along the first direction X to widen the support surface of the transport vehicle 200 on one side, or may be symmetrically arranged on both sides of the transport vehicle 200 along the first direction X to widen both sides of the transport vehicle 200, thereby reducing the widening dimension required to be increased on one side, making it easier to set the fixing fixture 100. When the fixing fixture 100 is symmetrically arranged on both sides of the transport vehicle 200, the specific structural forms of the paired fixing fixtures 100 may be the same.

[0046] For the convenience of description, a single-sided fixing tool 100 is taken as an example to illustrate the specific structure of the fixing tool 100 .

[0047] See also Figure 2 and Figure 3 In some optional embodiments, the carrying platform 2 is rotatably connected to the base 1, and the rotation axes of the carrying platform 2 and the base 1 are extended along the second direction Y, and the second direction Y intersects with the first direction X. In the open state, the carrying platform 2 is flipped relative to the base 1 and forms a carrying surface. In the retracted state, the carrying platform 2 is flipped in the opposite direction relative to the base 1 and is retracted on one side of the base 1.

[0048] The switching of the carrying platform 2 between the open state and the retracted state can be achieved by flipping the carrying platform 2 open. By flipping the carrying platform 2 open, in the retracted state, the carrying platform 2 can be set close to the base 1 or even stored in the base 1 to save space when not in use.

[0049] It can be understood that the second direction Y can be parallel to the support surface of the transport vehicle 200 to vertically flip the carrying platform 2 open, and the second direction Y can also be perpendicular to the support surface of the transport vehicle 200 to horizontally flip the carrying platform 2 open, as long as the carrying platform 2 can be flipped relative to the base 1 to extend out of the outer edge of the transport vehicle 200.

[0050] In some other optional embodiments, the carrying platform 2 is movably connected to the base 1 along the first direction X (not shown in the figure). In the open state, the carrying platform 2 moves relative to the base 1 along the first direction X away from the side of the transport vehicle 200 and extends out of the outer edge of the transport vehicle 200. In the retracted state, the carrying platform 2 moves relative to the base 1 along the first direction X toward the transport vehicle 200 and retracts into the base 1 to ensure the safety of the installation ship.

[0051] Therefore, the switching of the carrying platform 2 between the open state and the retracted state can also be realized by horizontal movement. The specific opening method of the carrying platform 2 can be selected according to the transportation tool 200, etc. Optionally, the carrying platform 2 can be driven to move horizontally relative to the base 1 by means of a motor screw, a hydraulic rod, a gear rack, etc.

[0052] For ease of description, the specific structure of the fixing tool 100 is explained below by taking the flip-opening method as an example.

[0053] See also Figure 3 In some optional embodiments, the fixed tool 100 further includes a third driving unit 5, which is used to drive the load-bearing platform 2 to switch between the open state and the retracted state. The third driving unit 5 may include a winch 51 and a wire rope 52, the winch 51 is arranged on the base 1, the wire rope 52 is connected to the load-bearing platform 2, and the winch 51 can drive the wire rope 52 to reel, thereby driving the load-bearing platform 2 to rotate relative to the base 1 through the wire rope 52.

[0054] Furthermore, a fixed pulley 24 may be provided on the bearing platform 2, and the steel wire rope 52 may be connected to the fixed pulley 24 on the bearing platform 2 after being led out from the hoist 51, so as to more stably drive the bearing platform 2 to rotate relative to the base 1. In addition, a connecting cavity is provided through the base 1 along the first direction X, and a supporting platform is provided on the side of the base 1 away from the bearing platform 2 along the first direction X corresponding to the connecting cavity, and the hoist 51 may be provided on the supporting platform, and the steel wire rope 52 of the hoist 51 is passed through the connecting cavity in the base 1 and connected to the fixed pulley 24 of the bearing platform 2, so as to facilitate the installation of the hoist 51.

[0055] It is understandable that in some other embodiments, the third driving unit 5 may also be configured as a hydraulic cylinder or the like, which can drive the supporting platform 2 to rotate relative to the base 1 .

[0056] In some optional embodiments, the number of bases 1 is more than two, and the more than two bases 1 are arranged at intervals along the second direction Y, and the carrying platform 2 is rotatably connected to each base 1. By providing multiple bases 1, the carrying platform 2 can be connected through multiple points, thereby improving the stability of the carrying platform 2.

[0057] Optionally, there are more than two third driving parts 5 , and each third driving part 5 can be correspondingly arranged on each base 1 . Each third driving part 5 synchronously drives the rotation of the carrying platform 2 to more stably and reliably drive the carrying platform 2 to flip relative to the base 1 .

[0058] See also Figure 3 In some optional embodiments, the fixing tool 100 further includes a first connecting component 3, which is connected to the carrying platform 2 and can provide a force to the carrying platform 2 to inhibit the rotation of the carrying platform 2 when the carrying platform 2 is in an open state.

[0059] It is understandable that the first connecting component 3 provides a force to inhibit the rotation of the supporting platform 2, which means that when the supporting platform 2 is in an open state, it can be fixed at the angle between the base 1 and the supporting platform 2 to ensure that the supporting platform 2 can be fixed at a preset angle.

[0060] It includes two parts, one part is to suppress the flipping of the carrying platform 2, and the other part is to suppress the reverse flipping of the carrying platform 2, thereby reducing the requirements for the winch 51. The winch 51 is only used to drive the carrying platform 2 to flip. On the other hand, it can also optimize the force distribution of the carrying platform 2, reduce the force at the connection between the carrying platform 2 and the base 1, and improve the reliability of the fixed tooling 100.

[0061] Optionally, the first connecting assembly 3 may be supported along the first direction X on an end of the carrying platform 2 away from the transportation vehicle 200 to better transmit force.

[0062] It can be understood that the first connecting component 3 can be connected to one side of the bearing surface of the bearing platform 2, and / or, the first connecting component 3 can also be connected to the side of the bearing platform 2 facing away from the bearing surface. For example, it can be configured to abut against a flip rib between the bearing platform 2 and the support arm, that is, the first connecting component 3 can suppress the rotation of the bearing platform 2 when the bearing platform 2 is in the open state.

[0063] See also Figure 3 In some optional embodiments, the base 1 includes a main support 11 and an auxiliary support 12 connected at the ends, and the main support 11 and the auxiliary support 12 form a preset angle along the flipping direction of the supporting platform 2; wherein the main support 11 is arranged on the transport vehicle 200, the supporting platform 2 is rotatably connected to the auxiliary support 12, and one end of the first connecting component 3 is connected to the auxiliary support 12, and the other end is connected to the supporting platform 2.

[0064] By setting the base 1 as a main support 11 and an auxiliary support 12, the first connecting component 3 can be set between the auxiliary support 12 and the supporting platform 2, and connected to the auxiliary support 12 and the supporting platform 2 respectively, so that the force of the first connecting component 3 can form a certain angle with the supporting platform 2, further optimizing the force of the supporting platform 2 and the first connecting component 3.

[0065] See also Figure 3 and Figure 4 In some optional embodiments, the first connecting component 3 includes a plurality of connecting segments 31 arranged successively, and two adjacent connecting segments 31 are hinged, so that in the open state, the plurality of connecting segments 31 can be arranged in the same direction to achieve force transmission, and in the retracted state, the plurality of connecting segments 31 can be relatively rotated and folded to avoid interference and save space.

[0066] Optionally, the first connecting component 3 can also be configured as a flexible structure such as a steel wire or a chain, that is, the multiple connecting segments 31 can be straightened to transmit force in the open state, and can be rolled up to save space in the retracted state.

[0067] See also Figures 2 to 5 To further save space, in some optional embodiments, the auxiliary support 12 is rotatably connected to the main support 11, and the rotation axes of the auxiliary support 12 and the main support 11 are extended along the second direction Y, and the second direction Y intersects with the first direction X. The base 1 includes a first state and a second state. In the first state, the auxiliary support 12 is flipped open to a preset angle relative to the main support 11. In the second state, the auxiliary support 12 is flipped in the opposite direction relative to the main support 11 and is stored on one side of the main support 11.

[0068] By rotatably connecting the auxiliary support 12 to the main support 11, after the blade 300 is hoisted, the auxiliary support 12 can also be turned over and stored on one side of the main support 11, thereby further reducing the occupied volume of the fixing tool 100 and optimizing the space.

[0069] In order to drive the auxiliary support 12 to rotate relative to the main support 11, in some optional embodiments, the base 1 also includes a first driving unit 13 and a crank-connecting rod mechanism 14. The crank-connecting rod mechanism 14 includes a crank 141 and a connecting rod 142 that are hinged to each other. The crank 141 is rotatably connected to the main support 11, and the connecting rod 142 is connected to the auxiliary support 12. The first driving unit 13 is used to drive the crank 141 to rotate, so as to drive the base 1 to switch between the first state and the second state through the connecting rod 142.

[0070] For example, a crank-connecting rod mechanism 14 can be provided to drive the auxiliary support 12 to rotate relative to the main support 11. The crank-connecting rod mechanism 14 occupies a small space and only requires a motor drive, which is convenient to set up. The crank 141 and the first drive part 13 can both be provided on the main support 11, which is convenient for installation, connection and wiring, and can simplify the structure and improve reliability.

[0071] Optionally, in addition to setting up the crank-connecting rod mechanism 14, the auxiliary support 12 can also be driven by a hydraulic cylinder to rotate relative to the main support 11, or a gear set can be set at the connecting end of the auxiliary support 12 and the main support 11, so that the auxiliary support 12 can rotate relative to the main support 11.

[0072] See also Figures 3 to 5 In some optional embodiments, the main support 11 includes a first support portion 111 and a second support portion 112 spaced apart along the second direction Y, and the auxiliary support 12 is sandwiched between the first support portion 111 and the second support portion 112 along the second direction Y. By providing the first support portion 111 and the second support portion 112, the auxiliary support 12 can be limited, thereby improving the stability of the auxiliary support 12 during flipping and preventing it from tipping over.

[0073] In some other embodiments, the auxiliary support 12 may also include a first support portion 111 and a second support portion 112 (not shown in the figure), and the main support 11 is clamped between the first support portion 111 and the second support portion 112 along the second direction Y, which can also improve the stability of the auxiliary support 12 during flipping.

[0074] Optionally, the fixing tool 100 further includes a reinforcing rib 4, which is disposed at the connection between the base 1 and the transport vehicle 200 to increase the connection strength between the fixing tool 100 and the transport vehicle 200 and ensure safety. When there are more than two bases 1, each base 1 may be provided with a reinforcing rib 4 along the second direction Y to further ensure safety and prevent rollover.

[0075] Please also read Figures 1 to 6 Considering the single-blade lifting method, after the blade 300 is transferred to the transport vehicle 200, in addition to ensuring the support requirements of the transport vehicle 200 for the blade 300, the size of the gap between the blade 300 and the supporting surface of the transport vehicle 200 must also be considered to ensure that the blade 300 lifting device can extend under the blade 300 to clamp the blade 300.

[0076] In order to meet the lifting requirements of the blade 300 hoist for the blade 300, in some optional embodiments, the supporting platform 2 includes a first supporting part 21, a second supporting part 22 and a lifting mechanism 23. The first supporting part 21 is rotatably connected to the base 1. The lifting mechanism 23 is arranged on the first supporting part 21 and is used to drive the second supporting part 22 to rise and fall along a third direction Z relative to the first supporting part 21. The supporting surface is arranged on the second supporting part 22, and the third direction Z intersects with the first direction X.

[0077] By setting up the lifting mechanism 23, the second bearing part 22 can be driven to rise along the third direction Z relative to the first bearing part 21, so as to form a certain gap between the blade 300 and the supporting surface of the transportation tool 200 to meet the clamping needs of the blade 300 hanger. At the same time, the distance between the second bearing part 22 and the first bearing part 21 along the third direction Z is adjustable, so as to meet the requirements of different blade 300 hangers for the clearance height below the blade 300, thereby improving applicability.

[0078] In addition, after the blade 300 is hoisted, the lifting mechanism 23 can also drive the second bearing part 22 to descend along the third direction Z relative to the first bearing part 21, so that when the bearing platform 2 is in the retracted state, the space occupied by the fixing tool 100 can be saved, which is more convenient to use.

[0079] See also Figure 6 In some optional embodiments, the lifting mechanism 23 includes a scissor arm 231 and a second driving portion 232. Along the third direction Z, one end of the scissor arm 231 is connected to the first bearing portion 21, and the other end is connected to the second bearing portion 22. The second driving portion 232 is used to drive the scissor arm 231 to open and close, so as to drive the second bearing portion 22 to rise and fall along the third direction Z relative to the first bearing portion 21.

[0080] By setting the lifting mechanism 23 to a straight-up and straight-down driving mode, when the lifting mechanism 23 drives the second carrying part 22 to descend along the third direction Z relative to the first carrying part 21, the second carrying part 22 can be at least partially embedded in the first carrying part 21, and even the first carrying part 21 and the second carrying part 22 can be arranged in the same plane, so as to further save the space occupied by the fixing tool 100 and be more convenient to use.

[0081] Optionally, the number of the supporting arms is more than two, so that the second bearing portion 22 can be supported at multiple points, providing a more stable support.

[0082] Optionally, the second driving part 232 can be configured as a ball screw and a gear rack, and can drive the scissor arm 231 to open and close to realize the lifting of the second bearing part 22. In addition, in some other embodiments, the lifting can also be realized by hydraulic cylinder lifting or gear chain lifting, and the present application is not limited thereto.

[0083] See also Figures 1 to 7 The embodiment of the present application further provides a method for transporting a blade 300, comprising:

[0084] The fixing tool 100 of the above embodiment is provided, the base 1 is set on the transportation vehicle 200, the carrying platform 2 is switched to an open state, and the carrying surface of the carrying platform 2 is at least partially protruded from the outer edge of the transportation vehicle 200.

[0085] The blade 300 is placed on the carrying surface of the carrying platform 2 .

[0086] After the transport vehicle 200 moves to the designated location, the blades 300 are unloaded and the carrying platform 2 is switched to a retracted state.

[0087] In the transportation method of the embodiment of the present application, the carrying platform 2 can be switched to the open state when transporting the blade 300, so that the carrying platform 2 is set to protrude from the outer edge of the transport tool 200, thereby expanding the maximum span of the fixed point of the transport tool 200 to meet the support requirements for the blade 300 of the large-capacity unit and ensure the feasibility of single-blade hoisting. In addition, after the blade 300 is hoisted, the carrying platform 2 can be switched to the retracted state to at least partially retract the carrying platform 2 into the transport tool 200 to reduce the impact on the travel of the transport tool 200, thereby eliminating the need for frequent disassembly and assembly of the fixed tooling 100, greatly improving the construction efficiency on site.

[0088] In some optional embodiments, the carrying platform 2 includes a first carrying portion 21, a second carrying portion 22 and a lifting mechanism 23, the first carrying portion 21 is rotatably connected to the base 1, and the carrying surface is arranged on the second carrying portion 22;

[0089] Before placing the blade 300 on the carrying surface of the carrying platform 2 , the method further includes: driving the second carrying portion 22 to rise along the third direction Z by a preset distance relative to the first carrying portion 21 .

[0090] Therefore, the second bearing part 22 can be driven to rise relative to the first bearing part 21 through the lifting mechanism 23 to form a certain gap between the blade 300 and the transportation tool 200 to meet the clamping needs of the blade 300 hanger. At the same time, the distance between the second bearing part 22 and the first bearing part 21 along the third direction Z is adjustable, so as to meet the requirements of different blade 300 hangers for the clearance height below the blade 300 and improve applicability.

[0091] In addition, after the blade 300 is hoisted, the second bearing part 22 can be driven to descend along the third direction Z relative to the first bearing part 21 through the lifting mechanism 23, so that when the bearing platform 2 is in the retracted state, the space occupied by the fixed tooling 100 can be saved to avoid affecting the normal driving of the transport vehicle 200.

[0092] Although the present application has been described with reference to preferred embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present application. In particular, the various technical features mentioned in the various embodiments may be combined in any manner as long as there are no structural conflicts. The present application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
