[0002] Wind energy is a clean, pollution-free, renewable energy source. Using wind power to generate electricity is very environmentally friendly. In order to improve the operating safety of wind turbines, relevant performance tests need to be carried out on wind turbine blades before they are put into operation to simulate the actual load conditions of the blades.

[0003] During the inspection of wind turbine blades, it is usually necessary to slide the corresponding ground anchor device into the guide rail of the "grooved embedded track cleaning device" disclosed in the Chinese utility model patent with application number 202322631035.2, and connect the wind turbine blades and the ground anchor device through a cable. At the same time, the position of the ground anchor device in the guide rail is changed according to the actual inspection needs, so as to truly simulate various wind field conditions.

[0004] However, in actual use, it was found that this type of embedded guide rail not only could not withstand the vertical pull-out force generated during the test for a long time; it would also produce deviations during the track casting process, thereby increasing the horizontality error after the guide rail was cast, and thus affecting normal inspection work.

[0045] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in combination with the implementation modes and the accompanying drawings.

[0046] The most critical concept of the present invention is that the design ensures that the horizontality of the track meets the design requirements by changing the support angle of the horizontal adjustment component; at the same time, during the pouring process, the end of the track away from the pouring trough is connected to the positioning device, which can avoid the track from being offset due to shaking, thereby better ensuring that the horizontality of the track after pouring can meet the test requirements of the wind turbine blades.

[0047] Please refer to Figures 1 to 10 The loading device track provided by the present invention comprises a positioning device 1, a horizontal adjustment component 2, a support body 3 and a track 4;

[0048] Track 4 is a groove-like structure;

[0049] The foundation body 3 is provided with a casting trough 31;

[0050] The track 4 is connected to the bottom of the casting trough 31 through the horizontal adjustment component 2, and the notch direction of the track 4 is consistent with the notch direction of the casting trough 31;

[0051] During pouring, the positioning device 1 is arranged at the notch of the pouring trough 31 , and one end of the track 4 close to the notch is connected to the positioning device 1 .

[0052] Specifically, the positioning devices 1 are arranged at intervals at the notches of the casting trough 31 along the extending direction of the casting trough 31 .

[0053] From the above description, it can be seen that the beneficial effects of the present invention are: providing a loading device track, connecting the casting trough 31 and the track 4 through the horizontal adjustment component 2, so that the staff can adjust the corresponding support angle according to the actual structure of the track 4, thereby ensuring that the horizontality of the track 4 can meet the design requirements; at the same time, during the casting process, the end of the track 4 away from the casting trough 31 is connected to the positioning device 1, which can avoid the track 4 from being offset due to shaking, thereby better ensuring that the horizontality of the track 4 after casting can meet the test requirements of the wind turbine blades; compared with the existing loading device track, it can not only improve the overall construction efficiency and construction accuracy, but also save the time and labor costs increased due to rework.

[0054] Further, the track 4 includes a first channel steel 41, a second channel steel 42 and a third channel steel 43 which are connected in sequence;

[0055] The first channel steel 41 and the third channel steel 43 are symmetrically arranged at the notch of the second channel steel 42, and one side edge of the first channel steel 41 and one side edge of the third channel steel 43 are respectively connected to the corresponding side edges of the second channel steel 42;

[0056] The bottom of the first channel steel 41 and the bottom of the third channel steel 43 are arranged opposite to each other;

[0057] The notches of the first channel steel 41 and the third channel steel 43 are respectively arranged opposite to the corresponding side walls of the casting trough 31 .

[0058] Specifically, the notch direction of the second channel steel 42 is consistent with the notch direction of the casting trough 31; and the distance between the bottom of the first channel steel 41 and the bottom of the third channel steel 43 ( Figure 1 α in the figure is smaller than the slot spacing of the second channel steel 42 ( Figure 1 β in .

[0059] Further, the level adjustment assembly 2 includes a first threaded rod 21, and a first leveling nut 22 and a first locking nut 23 sleeved on the outside of the first threaded rod 21;

[0060] During the initial installation, the first threaded rod 21 passes through the side wall where the first channel steel 41 is connected to the second channel steel 42, or passes through the side wall where the third channel steel 43 is connected to the second channel steel 42;

[0061] The first leveling nut 22 and the first locking nut 23 respectively contact the two sides of the thickness direction of the side wall where the first channel steel 41 and the second channel steel 42 are connected, or respectively contact the two sides of the thickness direction of the side wall where the third channel steel 43 and the second channel steel 42 are connected.

[0062] Specifically, the staff can increase or decrease the number of the first leveling nut 22 and the first locking nut 23 according to actual needs, and the first leveling nut 22 and the first locking nut 23 have the same structure, and their positions can be replaced with each other, that is, in the vertical direction, the nut located below the thickness direction of the side wall where the first channel steel 41 / the third channel steel 43 is connected to the second channel steel 42 is the first leveling nut 22, otherwise it is the first locking nut 23.

[0063] From the above description, it can be seen that the design has made specific improvements to the component structure of the track 4 and the component structure of the horizontal adjustment component 2, so that while the horizontal adjustment component 2 can effectively support the track 4, it can also provide structural support for adjusting the horizontality of the track 4, thereby ensuring that the quality of the track 4 after casting can meet the design requirements.

[0064] Furthermore, the positioning device 1 includes a positioning channel steel 11, a leveling assembly 12, a locking member 13 and a limiting plate 14;

[0065] The limiting plate 14 includes a first plate member 141 and a second plate member 142 which are connected in sequence and form an L shape;

[0066] During pouring, the notches of the positioning channel steel 11 and the pouring groove 31 are arranged opposite to each other, and the two ends of the positioning channel steel 11 in the extension direction are connected to the base body 3 through the leveling assembly 12;

[0067] The side wall of the first channel steel 41 away from the second channel steel 42 and the side wall of the third channel steel 43 away from the second channel steel 42 are both connected to the positioning channel steel 11 through the locking member 13;

[0068] The limiting plate 14 is connected to the positioning channel steel 11 through the first plate member 141 , and both ends of the second plate member 142 in the width direction are in conflict with the bottom of the first channel steel 41 and the bottom of the third channel steel 43 .

[0069] Specifically, the locking member 13 includes a second threaded rod 131 and a second locking nut 132 sleeved on the outside of the second threaded rod 131;

[0070] When the positioning channel steel 11 is connected to the rail 4, the corresponding second threaded rod 131 penetrates the bottom of the positioning channel steel 11 and the side wall of the first channel steel 41 away from the second channel steel 42, or penetrates the bottom of the positioning channel steel 11 and the side wall of the third channel steel 43 away from the second channel steel 42;

[0071] Both sides of the bottom of the positioning channel steel 11 in the thickness direction, both sides of the side wall of the first channel steel 41 away from the second channel steel 42 in the thickness direction, and both sides of the side wall of the third channel steel 43 away from the second channel steel 42 in the thickness direction all conflict with the second locking nut 132;

[0072] The leveling assembly 12 includes a third threaded rod 121, and a second leveling nut 122 and a third locking nut 123 sleeved on the outside of the third threaded rod 121;

[0073] When the positioning channel steel 11 is connected to the base body 3 , the third threaded rod 121 penetrates the bottom of the positioning channel steel 11 , and both sides of the bottom of the positioning channel steel 11 in the thickness direction respectively conflict with the second leveling nut 122 and the third locking nut 123 .

[0074] The staff can increase or decrease the number of the second leveling nut 122 and the third locking nut 123 according to actual needs, and the second leveling nut 122 and the third locking nut 123 have the same structure, and their positions can be replaced with each other, that is, in the vertical direction, the nut located below the thickness direction of the bottom of the positioning channel steel 11 is the second leveling nut 122, otherwise it is the third locking nut 123.

[0075] As can be seen from the above description, the design has made specific modifications to the component structure of the positioning device 1. By setting the second leveling nut 122 on the third threaded rod 121, it can be ensured that the positioning channel steel 11 will not affect the horizontality of the track 4 after the initial installation after being connected to the track 4, so that the quality of the track 4 after casting can meet the normal detection requirements; at the same time, the track 4 is connected to the positioning channel steel 11 through the locking member 13, which can improve the stability of the track 4 during the casting process, and avoid the track 4 from shaking and deviating, thereby increasing the horizontality error after casting, so as to affect the casting quality of the track 4; and before casting, the second plate 142 is abutted between the first channel steel 41 and the third channel steel 43, which can play a certain supporting role for the first channel steel 41 and the third channel steel 43, and avoid the first channel steel 41 and the third channel steel 43 from fitting each other during the casting process, so that the slot spacing between the first channel steel 41 and the third channel steel 43 cannot meet the design requirements, thereby affecting the subsequent normal inspection work of the fan blades.

[0076] Furthermore, the above-mentioned loading device track further includes a stiffening rib 5;

[0077] Along the extension direction of the casting trough 31, the stiffening ribs 5 are arranged at intervals in the first channel steel 41 or the third channel steel 43;

[0078] The horizontal adjustment assembly 2 is connected to the rail 4 via the stiffening rib 5 .

[0079] Specifically, the stiffening rib 5 includes a connecting plate 51 and a supporting plate 52; the plane where the connecting plate 51 is located is perpendicular to the plane where the supporting plate 52 is located, and the connecting plate 51 divides the supporting plate 52 into two halves; the interior of the first channel steel 41 or the interior of the third channel steel 43 is connected to the connecting plate 51; the support plates 52 on both sides of the thickness direction of the connecting plate 51 are connected to the horizontal adjustment assembly 2; when the horizontal adjustment assembly 2 and the stiffening rib 5 are connected, the support plate 52 is fastened between the first leveling nut 22 and the first locking nut 23.

[0080] From the above description, it can be seen that by arranging corresponding stiffening ribs 5 inside the corresponding first channel steel 41 and the second channel steel 42, the pull-out bearing capacity of the track 4 can be effectively improved, thereby avoiding damage to the track 4 due to tension during the subsequent testing process, so that the track 4 can meet the corresponding test requirements, and then truly simulate the actual load condition of the blade.

[0081] Furthermore, the above-mentioned loading device track also includes transverse steel bars 6 and longitudinal steel bars 7;

[0082] Along the extension direction of the casting trough 31, the transverse steel bars 6 are arranged at intervals on the corresponding side walls of the casting trough 31;

[0083] One end of the transverse reinforcement 6 away from the side wall of the casting trough 31 is welded to the corresponding stiffening rib 5;

[0084] The transverse reinforcements 6 on the same side are connected via corresponding longitudinal reinforcements 7 .

[0085] Specifically, the extending direction of the longitudinal reinforcement 7 of the present invention is parallel to the extending direction of the casting trough 31 .

[0086] Furthermore, the above-mentioned loading device track also includes a casting layer 8;

[0087] During pouring, the pouring layer 8 is filled between the track 4 and the pouring trough 31;

[0088] The horizontal adjustment component 2 , the stiffening ribs 5 , the transverse reinforcement 6 and the longitudinal reinforcement 7 are arranged in the casting layer 8 .

[0089] From the above description, it can be seen that by arranging corresponding transverse steel bars 6 and longitudinal steel bars 7 in the casting trough 31, the connection strength between the track 4 and the casting trough 31 can be effectively improved; at the same time, the casting layer 8 serves as a connecting medium between the track 4 and the casting trough 31. Therefore, when the casting layer 8 is completely solidified, the transverse steel bars 6 and the longitudinal steel bars 7 can also further improve the toughness of the casting layer 8, so that under the traction between the casting trough 31, the transverse steel bars 6, the longitudinal steel bars 7, the horizontal adjustment component 2, the stiffening rib 5 and the casting layer 8, the pull-out bearing capacity of the track 4 can be better improved, thereby meeting the subsequent detection requirements.

[0090] Furthermore, the above-mentioned loading device track also includes a corrugated steel plate 32;

[0091] Corrugated steel plates 32 are provided on both side walls of the casting trough 31;

[0092] The corrugated steel plate 32 is provided with through holes;

[0093] The transverse reinforcement 6 passes through the through hole and is connected to the side wall of the casting trough 31 .

[0094] Specifically, the cross-section of the corrugated steel plate 32 is serrated, that is, it constitutes a serrated shear key, and the corrugated steel plate 32 is also provided with vertical stiffening ribs 321 to improve the deformation resistance of the corrugated steel plate 32; when in use, the corrugated steel plate is not removed, but is directly embedded in the casting trough 31 as part of the loading device track, and the concrete used in the subsequent casting work is fiber concrete, thereby effectively enhancing the overall pull-out resistance and crack resistance.

[0095] From the above description, it can be seen that the design has further optimized the structure of the casting trough 31. By arranging corrugated steel plates 32 with a serrated cross-section on both side walls of the casting trough 31 and arranging through holes on the corrugated steel plates, it can not only facilitate the positioning of the transverse steel bars 6 and improve the positioning accuracy of the transverse steel bars 6; it can also form shear force on the side walls of the casting trough 31, thereby further enhancing the overall pull-out resistance.

[0096] The present invention also provides a method for constructing a loading device track according to any one of the above items, comprising the following steps:

[0097] S1, presetting the level adjustment component 2 at the bottom of the casting trough 31, and adjusting the position of the support surface of the level adjustment component 2 until the levelness of the support surface of the level adjustment component 2 meets the design requirements;

[0098] S2, placing the track 4 on the supporting surface of the horizontal adjustment component 2, and fine-tuning the horizontality of the track 4 by the horizontal adjustment component 2 until the horizontality of the track 4 meets the design requirements;

[0099] S3, arranging the positioning device 1 and the notch of the casting trough 31 opposite to each other, and connecting the positioning device 1 and the foundation body 3;

[0100] S4, connecting one end of the track 4 close to its notch to the positioning device 1;

[0101] S5, filling the space between the casting trough 31 and the track 4 with corresponding casting materials until the casting materials are solidified, thereby completing the construction work of the loading device track.

[0102] From the above description, it can be seen that the device provides a specific construction method for the loading device track, thereby ensuring that the horizontality of the loading device track before and after casting meets the design requirements, thereby effectively improving the pull-out bearing capacity of the track 4 after casting, while also saving the time and labor costs increased by rework, thereby achieving the effect of improving construction efficiency and saving construction costs.

[0103] The present invention also provides a wind turbine blade test bench, comprising a wind turbine blade positioning seat 91, a cable 92, a ground anchoring device 93, and a loading device track of any of the above items;

[0104] The fan blade positioning seat 91 is arranged on the working surface of the support platform body 3;

[0105] The fan blade positioning seat 91 is arranged at one end of the loading device track in the length direction;

[0106] The ground anchoring device 93 is slidably connected to the loading device track;

[0107] When the wind blade to be tested is connected to the wind blade positioning seat 91 , the loading device track and the wind blade to be tested are located in the same vertical plane, and the wind blade to be tested is connected to the ground anchoring device 93 via the cable 92 .

[0108] Specifically, the ground anchoring device 93 is also provided with a corresponding motor, and the rotation of the motor can release (reduce the pulling force on the fan blades) and twist (increase the pulling force on the fan blades) the cable 92.

[0109] It can be seen from the above description that the design has made specific improvements to the component structure of the wind turbine blade test bench 9, thereby providing structural support for the wind turbine blade test bench 9 to simulate the actual load conditions of the wind turbine blades.

[0110] Further, the number of the loading device tracks is at least three;

[0111] The loading device tracks are arranged at intervals in the width direction of the wind turbine blade to be inspected.

[0112] From the above description, it can be seen that the design has made further improvements to the component structure of the wind blade test bench 9. By adding a loading device track, it is convenient for the staff to set the ground anchor device 93 on different loading device tracks according to actual needs, so that the wind blade test bench 9 of the present invention can simulate various different stress scenarios, so that the final experimental data can truly reflect the performance of the wind blades, and then facilitate the staff to make timely adjustments to the process parameters during the production process to improve the quality of the wind blades.

[0135] The working principle of the present invention is:

[0136] Installation and pouring phase of the loading device track:

[0137] First, after fixing the transverse reinforcement 6 and the horizontal adjustment component 2 at the specified position, cast the foundation body 3, and after the casting and curing are completed, demould the foundation body 3 to form a casting groove 31; then, the first channel steel 41, the second channel steel 42 and the third channel steel 43 are connected in sequence by bolts to form a track 4, and along the extension direction of the casting groove 31, the stiffening ribs 5 are welded at intervals inside the first channel steel 41 and the third channel steel 43, and the limit plate 14 is connected to the positioning channel steel 11, and the inside of the casting groove 31 is roughened; then, the track 4 is placed in the casting groove 31 by hoisting, and the track 4 is locked to the first threaded rod 21 by the first leveling nut 22 and the first locking nut 23. At the same time, the transverse reinforcement 6 and the horizontal adjustment component 2 are connected to the first channel steel 41 and the third channel steel 43. The ribs 6 are welded to the corresponding stiffening ribs 5, and the transverse reinforcement 6 on the same side is connected through the corresponding longitudinal reinforcement 7; then, the positioning channel steel 11 is locked to the third threaded rod 121 through the second leveling nut 122 and the third locking nut 123, and the two ends of the second plate 142 in the width direction are respectively in contact with the bottom of the first channel steel 41 and the bottom of the third channel steel 43, and at the same time, the side wall of the first channel steel 41 away from the second channel steel 42 and the side wall of the third channel steel 43 away from the second channel steel 42 are connected to the positioning channel steel 11 through the locking member 13; finally, the corresponding casting material is filled between the casting groove 31 and the track 4, and after solidification, a casting layer 8 is formed, thereby completing the installation and casting of the loading device track.

[0138] Inspection phases of fan blades:

[0139] First, fix the wind turbine blade to be inspected on the wind turbine blade positioning seat 91; then, according to the actual inspection requirements, the staff slides a corresponding number of ground anchor devices 93 in the corresponding loading device track through corresponding T-bolts, and moves the ground anchor device 93 to the designated inspection position; then, fix the two ends of the cable 92 on the wind turbine blade to be inspected and the ground anchor device 93 respectively; finally, start the relevant tensioning device set on the ground anchor device 93 to loosen the cable 92, thereby pulling the wind turbine blade to simulate the actual working conditions.

[0140] In summary, a loading device track provided by the present invention connects the casting trough and the track through a horizontal adjustment component, so that the staff can adjust the corresponding support angle according to the actual structure of the track, thereby ensuring that the horizontality of the track can meet the design requirements; at the same time, during the casting process, the end of the track away from the casting trough is connected to the positioning device, which can avoid the track from being offset due to shaking, thereby better ensuring that the horizontality of the track after casting can meet the test requirements of the wind turbine blades; compared with the existing loading device track, it can not only improve the overall construction efficiency and construction accuracy, but also save the time and labor costs increased by rework; by arranging a second leveling nut on the third threaded rod, the positioning groove can be ensured After the steel is connected to the track, it can not affect the horizontality of the track after the initial installation, so that the quality of the track after casting can meet the normal inspection requirements; at the same time, the track is connected to the positioning channel steel through a locking piece, which can improve the stability of the track during the casting process, and avoid the track shaking and offset, which increases the horizontality error after casting, so as to affect the casting quality of the track; and before casting, the second plate is abutted between the first channel steel and the third channel steel, which can play a certain supporting role for the first channel steel and the third channel steel, and avoid the first channel steel and the third channel steel from fitting each other during the casting process, so that the slot spacing between the first channel steel and the third channel steel cannot meet the design requirements, thereby affecting the subsequent normal inspection work of the fan blades.
