[0045] To make the technical contents of the present application, the purposes and effects achieved clear, the following will be described in conjunction with the embodiments and the accompanying drawings.

[0046] The most critical idea of the present application is that the design changes the support angle of the horizontal adjusting assembly, thereby ensuring that the levelness of the track can meet the design requirements; at the same time, in the pouring process, the end of the track away from the pouring groove is connected to the positioning device, so that the track can be prevented from deviating due to shaking, thereby better ensuring that the levelness of the track after pouring can meet the test requirements of the fan blade.

[0047] Please refer to Figures 1 to 10 The loading device track provided by the present application comprises a positioning device 1, a horizontal adjusting assembly 2, a bearing platform body 3 and a track 4.

[0048] The track 4 is in a groove structure.

[0049] The bearing platform body 3 is provided with a pouring groove 31.

[0050] The track 4 is connected to the groove bottom of the pouring groove 31 through the horizontal adjusting assembly 2, and the direction of the slot of the track 4 is consistent with the direction of the slot of the pouring groove 31.

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

[0052] Specifically, the positioning device 1 is arranged at the slot of the pouring groove 31 along the extension direction of the pouring groove 31.

[0053] From the above description, it can be seen that the present application has the beneficial effects that a loading device track is provided, the pouring groove 31 and the track 4 are connected through the horizontal adjusting assembly 2, so that the staff can adjust the corresponding support angle according to the actual structure of the track 4, thereby ensuring that the levelness of the track 4 can meet the design requirements; at the same time, in the pouring process, the end of the track 4 away from the pouring groove 31 is connected to the positioning device 1, so that the track 4 can be prevented from deviating due to shaking, thereby better ensuring that the levelness of the track 4 after pouring can meet the test requirements of the fan blade; compared with the existing loading device track, the present application can not only improve the overall construction efficiency and construction precision, but also save the time and labor cost increased due to rework.

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

[0055] The first channel steel 41 and the third channel steel 43 are symmetrically arranged at the opening of the second channel steel 42, and one side of the first channel steel 41 and one side of the third channel steel 43 are respectively connected to the corresponding side 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 set opposite to each other;

[0057] The openings of the first channel steel 41 and the third channel steel 43 are respectively set opposite to the sidewalls of the casting trough 31.

[0058] Specifically, the groove direction of the second channel steel 42 is consistent with the groove direction of the casting groove 31; and the distance between the bottom of the first channel steel 41 and the bottom of the third channel steel 43 is ( Figure 1 α) is less than the slot spacing of the second channel steel 42 ( Figure 1 (β in the text)

[0059] Furthermore, the leveling 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 initial installation, the first threaded rod 21 penetrates the side wall where the first channel steel 41 and the second channel steel 42 are connected, or penetrates the side wall where the third channel steel 43 and the second channel steel 42 are connected.

[0061] The first leveling nut 22 and the first locking nut 23 respectively abut against both 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 abut against both 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, staff can increase or decrease the number of the first leveling nut 22 and the first locking nut 23 according to actual needs. The first leveling nut 22 and the first locking nut 23 have the same structure and their positions can be interchanged. That is, in the vertical direction, the nut located below the thickness direction of the side wall where the first channel steel 41 / third channel steel 43 connects to the second channel steel 42 is the first leveling nut 22, and the nut located above it is the first locking nut 23.

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

[0064] Further, the positioning device 1 comprises a positioning channel steel 11, a leveling assembly 12, a locking piece 13 and a limiting plate 14;

[0065] The limiting plate 14 comprises a first plate piece 141 and a second plate piece 142 which are sequentially connected and constitute an L-shaped structure;

[0066] During pouring, the positioning channel steel 11 and the pouring channel 31 are oppositely arranged, and the two ends of the extension direction of the positioning channel steel 11 are connected with the main body 3 of the pile cap 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 connected with the positioning channel steel 11 through the locking piece 13;

[0068] The limiting plate 14 is connected with the positioning channel steel 11 through the first plate piece 141, and the two ends of the width direction of the second plate piece 142 respectively abut against the channel bottom of the first channel steel 41 and the channel bottom of the third channel steel 43.

[0069] Specifically, the locking piece 13 comprises a second threaded rod 131 and a second locking nut 132 sleeved outside the second threaded rod 131;

[0070] When the positioning channel steel 11 is connected with the track 4, the corresponding second threaded rod 131 penetrates the channel 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 channel 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] The two sides of the channel bottom of the positioning channel steel 11 in the thickness direction, the two sides of the side wall of the first channel steel 41 away from the second channel steel 42 in the thickness direction, and the two sides of the side wall of the third channel steel 43 away from the second channel steel 42 in the thickness direction all abut against the second locking nut 132;

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

[0073] When the positioning channel steel 11 is connected with the main body 3 of the pile cap, the third threaded rod 121 penetrates the channel bottom of the positioning channel steel 11, and the two sides of the channel bottom of the positioning channel steel 11 in the thickness direction respectively abut against the second leveling nut 122 and the third locking nut 123.

[0074] The number of the second leveling nut 122 and the third locking nut 123 can be increased or decreased according to actual needs, and the structures of the second leveling nut 122 and the third locking nut 123 are the same, and the positions of the second leveling nut 122 and the third locking nut 123 can be replaced, that is, in the vertical direction, the nut below the channel bottom of the positioning channel steel 11 in the thickness direction is the second leveling nut 122, and vice versa.

[0075] From the above description, the design makes specific modifications to the composition structure of the positioning device 1. By providing the second leveling nut 122 on the third threaded rod 121, the horizontal degree of the track 4 after the preliminary installation can be ensured after the positioning channel steel 11 is connected with the track 4, so that the quality of the poured track 4 can meet the normal detection requirements. At the same time, the track 4 is connected with the positioning channel steel 11 through the locking piece 13, which can improve the stability of the track 4 during pouring, avoid the horizontal error of the poured track 4 due to the deviation of the track 4, and affect the pouring quality of the track 4. Before pouring, the second plate 142 is abutted between the first channel steel 41 and the third channel steel 43, which can support the first channel steel 41 and the third channel steel 43, avoid the mutual adhesion of the first channel steel 41 and the third channel steel 43 during pouring, so that the slot distance between the first channel steel 41 and the third channel steel 43 cannot meet the design requirements, and then affect the subsequent normal detection work of the fan blade.

[0076] Further, the loading device track described above further comprises a stiffening rib 5.

[0077] The stiffening rib 5 is arranged in the first channel steel 41 or the third channel steel 43 in the extension direction of the pouring groove 31.

[0078] The horizontal adjustment assembly 2 is connected with the track 4 through the stiffening rib 5.

[0079] Specifically, the stiffening rib 5 comprises a connecting plate 51 and a supporting plate 52; the plane where the connecting plate 51 is located and the plane where the supporting plate 52 is located are perpendicular, and the connecting plate 51 bisects the supporting plate 52; the inside of the first channel steel 41 or the inside of the third channel steel 43 is connected with the connecting plate 51; the supporting plate 52 on both sides of the thickness direction of the connecting plate 51 is connected with the horizontal adjustment assembly 2; when the horizontal adjustment assembly 2 and the stiffening rib 5 are connected, the supporting plate 52 is fastened between the first leveling nut 22 and the first locking nut 23.

[0080] From the above description, by arranging the corresponding stiffening rib 5 in the inside of the corresponding first channel steel 41 and second channel steel 42, the pullout bearing capacity of the track 4 can be effectively improved, so as to avoid damage of the track 4 due to tension in the subsequent detection process, so that the track 4 can meet the corresponding test requirements, and then truly simulate the actual load condition of the blade.

[0081] Further, the loading device track described above further comprises a transverse steel bar 6 and a longitudinal steel bar 7.

[0082] Along the extension direction of the pouring groove 31, the transverse steel bar 6 is arranged on the corresponding side wall of the pouring groove 31.

[0083] The end of the transverse steel bar 6 away from the side wall of the pouring groove 31 is welded with the corresponding stiffening rib 5.

[0084] The transverse steel bars 6 on the same side are connected by corresponding longitudinal steel bars 7.

[0085] Specifically, the extension direction of the longitudinal steel bars 7 and the extension direction of the pouring groove 31 are parallel.

[0086] Further, the loading device track described above further comprises a pouring layer 8.

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

[0088] The horizontal adjustment assembly 2, the stiffening rib 5, the transverse steel bar 6 and the longitudinal steel bar 7 are arranged in the pouring layer 8.

[0089] As can be seen from the above description, by arranging corresponding transverse steel bars 6 and longitudinal steel bars 7 in the pouring groove 31, the connection strength between the track 4 and the pouring groove 31 can be effectively improved; at the same time, the pouring layer 8 acts as a connecting medium between the track 4 and the pouring groove 31, so that when the pouring layer 8 is completely solidified, the transverse steel bars 6 and the longitudinal steel bars 7 can further improve the toughness of the pouring layer 8, so that under the traction between the pouring groove 31, the transverse steel bar 6, the longitudinal steel bar 7, the horizontal adjustment assembly 2, the stiffening rib 5 and the pouring layer 8, the track 4 can better improve the anti-pulling bearing capacity, thereby meeting the subsequent detection requirements.

[0090] Further, the loading device track described above further comprises a profiled steel plate 32.

[0091] The two side walls of the pouring groove 31 are each provided with a profiled steel plate 32.

[0092] The profiled steel plate 32 is provided with a through hole.

[0093] The transverse steel bar 6 penetrates the through hole and is connected with the side wall of the pouring groove 31.

[0094] Specifically, the cross section of the profiled steel plate 32 is sawtooth-shaped, that is, a sawtooth-shaped shear key is formed, and the profiled steel plate 32 is further provided with a vertical stiffening rib 321 to improve the anti-deformation capacity of the profiled steel plate 32; in use, the profiled steel plate is not removed, but is directly embedded in the pouring groove 31 as part of the loading device track, and the concrete used in the subsequent pouring work is fiber concrete, thereby effectively enhancing the overall anti-pulling and anti-cracking performance.

[0095] As can be seen from the above description, the design further optimizes the structure of the pouring groove 31, by arranging the profiled steel plate 32 with a sawtooth-shaped cross section on the two side walls of the pouring groove 31 and arranging a through hole on the profiled steel plate, only the positioning work of the transverse steel bar 6 can be facilitated, the positioning accuracy of the transverse steel bar 6 can be improved, and shear force can be formed on the side wall of the pouring groove 31, thereby further enhancing the overall anti-pulling performance.

[0096] The application further provides a construction method of the loading device track.

[0097] S1, presetting the horizontal adjusting assembly 2 at the groove bottom of the pouring groove 31, and adjusting the position of the supporting surface of the horizontal adjusting assembly 2 until the levelness of the supporting surface of the horizontal adjusting assembly 2 meets the design requirement;

[0098] S2, placing the track 4 on the supporting surface of the horizontal adjusting assembly 2, and fine-tuning the levelness of the track 4 through the horizontal adjusting assembly 2 until the levelness of the track 4 meets the design requirement;

[0099] S3, oppositely arranging the positioning device 1 and the groove opening of the pouring groove 31, and connecting the positioning device 1 and the bearing body 3;

[0100] S4, connecting the track 4 with the positioning device 1 at the end close to the groove opening of the track 4;

[0101] S5, filling the corresponding pouring material between the pouring groove 31 and the track 4 until the pouring material solidifies, so as to complete the construction of the loading device track.

[0102] From the above description, it can be known that the application provides a specific construction method of the loading device track, so that the levelness of the loading device track before and after pouring meets the design requirement, thereby effectively improving the uplift bearing capacity of the track 4 after pouring, and saving the time and labor cost increased due to the need for rework, achieving the effect of improving the construction efficiency and saving the construction cost.

[0103] The application further provides a fan blade test bed, which comprises a fan blade positioning seat 91, a cable 92, a ground anchoring device 93, and the loading device track according to any one of the above.

[0104] The fan blade positioning seat 91 is arranged on the working surface of the bearing 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 in sliding connection with the loading device track.

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

[0108] Specifically, the ground anchoring device 93 is further provided with a corresponding motor, and the motor is rotated to release (reduce the pulling force on the fan blade) and wind (increase the pulling force on the fan blade) the cable 92.

[0109] From the above description, the design makes specific improvements to the component structure of the fan blade test bed 9, thereby providing structural support for the fan blade test bed 9 to simulate the actual load-bearing conditions of the fan blade.

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

[0111] In the width direction of the fan blade to be detected, the loading device tracks are arranged at intervals.

[0112] From the above description, the design further improves the component structure of the fan blade test bed 9 by adding loading device tracks, which allows the staff to set the ground anchoring device 93 at different loading device tracks according to actual needs, thereby enabling the fan blade test bed 9 of the present application to simulate various different force scenarios, allowing the experimental data obtained to truly reflect the performance of the fan blade, and further facilitating the staff to make timely adjustments to the process parameters during production and manufacturing to improve the quality of the fan blade.
