Description

Technical Field

[0001] The utility model belongs to the technical field of fan blade performance testing equipment, in particular to a loading device track and a fan blade test bench. Background Art

[0002] The following problems often occur during the installation and pouring of existing tracks used for wind turbine blade performance testing:

[0003] 1) During the initial installation, workers can only visually inspect and combine their work experience to determine whether the track's levelness meets the design requirements. Furthermore, if it is discovered after initial installation that the track's levelness does not meet the design requirements, the track cannot be adjusted quickly and conveniently. These two situations not only seriously affect the quality of the track after pouring, but also require additional labor costs to rework and repair the track to ensure that the track's levelness meets the requirements, thereby affecting construction efficiency and increasing construction costs.

[0004] 2) During pouring, the track is prone to shaking and deflection due to external forces. If not discovered in time, the horizontality of the track after pouring will have a large error, making the track unable to meet subsequent test requirements and unable to truly simulate the actual load conditions of the blade.

[0071] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and the accompanying drawings.

[0072] The most critical concept of the present invention is that the staff can freely adjust the support angle of the leveling component according to the structure of the track, so that the levelness of the track meets the design requirements; at the same time, a positioning component that can fix the positioning channel steel is provided on the base body, and the positioning channel steel and the track are connected by a locking piece, so that the track can be stably fixed in the casting trough before casting, so as to prevent the levelness of the track after casting from being affected by shaking.

[0073] Please refer to Figures 1 to 10 The loading device track provided by the present invention includes a base body 1, a positioning channel steel 2, a leveling assembly 3, a locking member 4 and a track 5. The base body 1 is provided with a casting trough 101;

[0074] Positioning components 7 are preset on the base body 1 located on both sides of the notch of the casting trough 101;

[0075] The positioning channel steel 2 is connected to the platform body 1 through the positioning component 7;

[0076] The leveling assembly 3 is preset at the bottom of the casting trough 101, and the track 5 is connected to the casting trough 101 through the leveling assembly 3;

[0077] The rail 5 is connected to the positioning channel steel 2 through the locking piece 4.

[0078] From the above description, it can be seen that the beneficial effects of the present invention are: providing a loading device track, by adjusting the position of the support surface of the leveling component 3, it is convenient for the staff to freely adjust the support angle of the track 5 according to the structure of the track 5, so that the horizontality of the track 5 can meet the design requirements; at the same time, a positioning component 7 that can fix the positioning channel steel 2 is provided on the base body 1, and the positioning channel steel 2 and the track 5 are connected by the locking member 4, so that the track 5 can be stably fixed to the casting trough 101 before casting, avoiding the horizontality of the track 5 after casting due to shaking. 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.

[0079] Furthermore, the track 5 includes a first channel steel 51, a second channel steel 52 and a third channel steel 53 which are connected in sequence;

[0080] The bottom of the first channel steel 51 and the bottom of the third channel steel 53 are arranged opposite to each other;

[0081] The notches of the first channel steel 51 and the third channel steel 53 are respectively arranged opposite to the corresponding side walls of the casting trough 101 .

[0082] Specifically, the first channel steel 51 and the third channel steel 53 are symmetrically arranged at the notch of the second channel steel 52; the notch direction of the second channel steel 52 is consistent with the notch direction of the casting trough 101; and the distance between the bottom of the first channel steel 51 and the bottom of the third channel steel 53 ( Figure 5 α in the figure) is smaller than the slot spacing of the second channel steel 52 ( Figure 5 β in ).

[0083] Furthermore, the leveling assembly 3 includes a first threaded rod 31 , and a first leveling nut 32 and a first locking nut 33 sleeved on the outside of the first threaded rod 31 ;

[0084] The first channel steel 51 and the third channel steel 53 are both connected to the bottom of the casting trough 101 through the first threaded rod 31;

[0085] The first leveling nut 32 and the first locking nut 33 respectively contact both sides of the thickness direction of the side wall connecting the first channel steel 51 and the second channel steel 52 , or respectively contact both sides of the thickness direction of the side wall connecting the third channel steel 53 and the second channel steel 52 .

[0086] Specifically, the staff can increase or decrease the number of the first leveling nut 32 and the first locking nut 33 according to actual needs, and the first leveling nut 32 and the first locking nut 33 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 51 / the third channel steel 53 is connected to the second channel steel 52 is the first leveling nut 32, otherwise it is the first locking nut 33.

[0087] From the above description, it can be seen that the design has made specific improvements to the component structure of the track 5 and the component structure of the leveling component 3, so that while the leveling component 3 can effectively support the track 5, it can also provide structural support for adjusting the horizontality of the track 5, thereby ensuring that the quality of the track 5 after casting can meet the design requirements.

[0088] Furthermore, the locking member 4 includes a second threaded rod 41 and a second locking nut 42 sleeved on the outside of the second threaded rod 41;

[0089] When the positioning channel steel 2 and the rail 5 are connected, the corresponding second threaded rod 41 passes through the bottom of the positioning channel steel 2 and the side wall of the first channel steel 51 away from the second channel steel 52, or passes through the bottom of the positioning channel steel 2 and the side wall of the third channel steel 53 away from the second channel steel 52;

[0090] Both sides of the bottom of the positioning channel steel 2 in the thickness direction, both sides of the side wall of the first channel steel 51 away from the second channel steel 52 in the thickness direction, and both sides of the side wall of the third channel steel 53 away from the second channel steel 52 in the thickness direction all conflict with the second locking nut 42.

[0091] From the above description, it can be seen that the design has made specific improvements to the composition structure of the locking member 4 and the positional relationship between the locking member 4 and the track 5, so as to ensure that the positioning channel steel 2 can be stably connected to the track 5, thereby improving the stability of the track 5 during the casting process, and avoiding the track 5 from shaking and offsetting, thereby increasing the horizontal error after casting, and affecting the casting quality of the track 5.

[0092] Furthermore, the above-mentioned loading device track further includes a limit plate 6;

[0093] The limiting plate 6 includes a first plate member 61 and a second plate member 62 which are connected in sequence and form an L shape;

[0094] The limiting plate 6 is connected to the positioning channel steel 2 through the first plate 61;

[0095] When the positioning channel steel 2 is connected to the rail 5 , both ends of the second plate 62 in the width direction respectively contact the bottom of the first channel steel 51 and the bottom of the third channel steel 53 .

[0096] From the above description, it can be seen that before pouring, the second plate 62 is pressed between the first channel steel 51 and the third channel steel 53, which can play a certain supporting role for the first channel steel 51 and the third channel steel 53, and avoid the first channel steel 51 and the third channel steel 53 from fitting each other during the pouring process, so that the slot spacing between the first channel steel 51 and the third channel steel 53 cannot meet the design requirements, thereby affecting the subsequent normal inspection work of the fan blades.

[0097] Furthermore, the positioning assembly 7 includes a third threaded rod 71, and a second leveling nut 72 and a third locking nut 73 sleeved on the outside of the third threaded rod 71;

[0098] When the positioning channel steel 2 is connected to the base body 1 , the third threaded rod 71 passes through the bottom of the positioning channel steel 2 , and both sides of the bottom of the positioning channel steel 2 in the thickness direction respectively conflict with the second leveling nut 72 and the third locking nut 73 .

[0099] Specifically, the staff can increase or decrease the number of the second leveling nut 72 and the third locking nut 73 according to actual needs, and the second leveling nut 72 and the third locking nut 73 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 2 is the second leveling nut 72, otherwise it is the third locking nut 73.

[0100] From the above description, it can be seen that the design has made specific improvements to the composition structure of the positioning assembly 7. By providing a second leveling nut 72 on the third threaded rod 71, it can be ensured that after the positioning channel steel 2 is connected to the track 5, it will not affect the horizontality of the track 5 after the initial installation, so that the quality of the cast track 5 can meet normal inspection requirements.

[0101] Furthermore, the above-mentioned loading device track further includes a stiffening rib 8;

[0102] Along the extension direction of the casting trough 101, the stiffening ribs 8 are arranged at intervals in the first channel steel 51 or the third channel steel 53;

[0103] The leveling assembly 3 is connected to the rail 5 via stiffening ribs 8 .

[0104] Specifically, the stiffening rib 8 includes a connecting plate 81 and a support plate 82; the plane where the connecting plate 81 is located is perpendicular to the plane where the support plate 82 is located, and the connecting plate 81 divides the support plate 82 into two halves; the interior of the first channel steel 51 or the interior of the third channel steel 53 is connected to the connecting plate 81; the support plates 82 on both sides of the thickness direction of the connecting plate 81 are connected to the leveling assembly 3; when the leveling assembly 3 and the stiffening rib 8 are connected, the support plate 82 is fastened between the first leveling nut 32 and the first locking nut 33.

[0105] From the above description, it can be seen that by arranging corresponding stiffening ribs 8 inside the corresponding first channel steel 51 and second channel steel 52, the pull-out bearing capacity of the track 5 can be effectively improved, thereby avoiding damage to the track 5 due to tension during the subsequent testing process, so that the track 5 can meet the corresponding test requirements and thus truly simulate the actual load conditions of the blade.

[0106] Furthermore, the above-mentioned loading device track further includes a casting layer 9, a transverse reinforcement 10 and a longitudinal reinforcement 11;

[0107] Along the extension direction of the casting trough 101, the transverse steel bars 10 are arranged at intervals on the corresponding side walls of the casting trough 101;

[0108] One end of the transverse reinforcement 10 away from the side wall of the casting trough 101 is welded to the corresponding stiffening rib 8;

[0109] The transverse reinforcements 10 on the same side are connected by corresponding longitudinal reinforcements 11;

[0110] During pouring, the pouring layer 9 is filled between the rail 5 and the pouring trough 101 .

[0111] Preferably, the extending direction of the longitudinal reinforcement 11 of the present invention is parallel to the extending direction of the casting trough 101 .

[0112] From the above description, it can be seen that by arranging corresponding transverse steel bars 10 and longitudinal steel bars 11 in the casting trough 101, the connection strength between the track 5 and the casting trough 101 can be effectively improved; at the same time, the casting layer 9 serves as a connecting medium between the track 5 and the casting trough 101. Therefore, when the casting layer 9 is completely solidified, the transverse steel bars 10 and the longitudinal steel bars 11 can also further improve the toughness of the casting layer 9. Therefore, under the traction between the casting trough 101, the transverse steel bars 10, the longitudinal steel bars 11, the leveling component 3 and the casting layer 9, the pull-out bearing capacity of the track 5 can be better improved, thereby meeting the subsequent detection requirements.

[0113] Furthermore, the above-mentioned loading device track further includes a corrugated steel plate 102;

[0114] Corrugated steel plates 102 are provided on both side walls of the casting trough 101;

[0115] The corrugated steel plate 102 is provided with through holes;

[0116] The transverse reinforcement 10 passes through the through hole and is connected to the side wall of the casting trough 101 .

[0117] Specifically, the cross-section of the corrugated steel plate 102 is serrated, that is, it constitutes a serrated shear key, and the corrugated steel plate 102 is also provided with vertical stiffening ribs 103 to improve the deformation resistance of the corrugated steel plate 102; when in use, the corrugated steel plate is not removed, but is directly embedded in the casting trough 101 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.

[0118] From the above description, it can be seen that the design further optimizes the structure of the casting trough 101. By arranging corrugated steel plates 102 with serrated cross-sections on both side walls of the casting trough 101 and providing through holes on the corrugated steel plates, it can not only facilitate the positioning of the transverse steel bars 10 and improve the positioning accuracy of the transverse steel bars 10; it can also form shear force on the side walls of the casting trough 101, thereby further enhancing the overall pull-out resistance.

[0119] The present invention further provides a wind turbine blade test bench 12, comprising a wind turbine blade positioning seat 121, a cable 122, a ground anchoring device 123, and a loading device track of any of the above items;

[0120] The fan blade positioning seat 121 is arranged on the working surface of the support body 1;

[0121] The fan blade positioning seat 121 is arranged at one end of the length direction of the loading device track;

[0122] The ground anchoring device 123 is slidably connected to the loading device track;

[0123] When the wind blade to be inspected is connected to the wind blade positioning seat 121 , the loading device track and the wind blade to be inspected are located in the same vertical plane, and the wind blade to be inspected is connected to the ground anchoring device 123 via the cable 122 .

[0124] Specifically, the ground anchoring device 123 is also provided with a corresponding motor, which rotates to release (reduce the pulling force on the fan blades) and twist (increase the pulling force on the fan blades) the cable 122.

[0125] As can be seen from the above description, this design makes specific improvements to the component structure of the wind blade test bench 12, thereby providing structural support for the wind blade test bench 12 to simulate the actual load conditions of the wind blades.

[0126] Further, the number of the loading device tracks is at least three;

[0127] The loading device tracks are arranged at intervals in the width direction of the wind turbine blade to be inspected.

[0128] 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 12. By increasing the number of loading device tracks, the staff can set the ground anchor device 123 in different loading device tracks according to actual needs, so that the wind blade test bench 12 of the utility model can simulate various different stress scenarios, so that the experimental data finally obtained can truly reflect the performance of the wind blade, and thus facilitate the staff to make timely adjustments to the process parameters during the production process to improve the quality of the wind blade.
