[0051] To describe in detail the technical content, achieved purpose and effects of the present utility model, the following is described in conjunction with the implementation modes and with reference to the drawings.

[0052] The most crucial concept of the present utility model lies in: presetting a corresponding horizontal adjustment rod group at the bottom of the casting groove, which can provide structural support for the staff to adjust the corresponding levelness before and after the installation of the track; at the same time, connecting the casting groove with the stiffening rib assembly through the connecting piece can effectively improve the overall connection strength, so that the cast track can better withstand the vertical tension generated during the test.

[0053] Please refer to Figures 1 to 6 , the loading device track provided by the present utility model includes a casting groove 1 and a track 2 arranged in the casting groove 1. In the extending direction of the casting groove 1, a horizontal adjustment rod group 3 is preset at the bottom of the casting groove 1, and a connecting piece 4 is preset on the side wall of the casting groove 1;

[0054] In the extending direction of the track 2, stiffening rib assemblies 21 are arranged at intervals on the track 2;

[0055] Both the connecting piece 4 and the horizontal adjustment rod group 3 are connected to the stiffening rib assembly 21.

[0056] Specifically, the extending direction of the track 2 of the present utility model is parallel to the extending direction of the casting groove 1.

[0057] As can be seen from the above description, the beneficial effects of the present utility model are as follows: A loading device track is provided. By presetting a corresponding horizontal adjusting rod group 3 at the bottom of the pouring groove 1, it provides structural support for the staff to adjust the level before and after the installation of the track 2 according to the actual situation. At the same time, by connecting the pouring groove 1 with the stiffening rib assembly 21 through the connecting piece 4, the overall connection strength can be effectively improved. Compared with the traditional track 2 structure, the loading device track of the present utility model can not only ensure that the level of the track 2 after pouring meets the design requirements, but also enhance the strength of the track 2 itself and the connection force between the track 2 and the pouring groove 1, thereby effectively enhancing the uplift bearing capacity of the track 2, and further enabling the track 2 after pouring to better withstand the vertical tension generated during the test.

[0058] Further, the track 2 includes a first channel steel 22, a second channel steel 23, and a third channel steel 24 connected in sequence;

[0059] The lower flanges of the first channel steel 22 and the third channel steel 24 are respectively arranged at the ends of the second channel steel 23 close to its own slot opening;

[0060] The slot openings of the first channel steel 22 and the third channel steel 24 are respectively arranged opposite to the side walls of the corresponding pouring groove 1;

[0061] There is a spacing between the bottom of the first channel steel 22 and the bottom of the third channel steel 24.

[0062] Further, the spacing between the bottom of the first channel steel 22 and the bottom of the third channel steel 24 is less than the slot spacing of the second channel steel 23.

[0063] Specifically, the slot opening direction of the second channel steel 23 is the same as the slot opening direction of the pouring groove 1; and the distance between the bottom of the first channel steel 22 and the bottom of the third channel steel 24 is Figure 1 α in; the slot spacing of the second channel steel 23 is Figure 1 β in; the lower flanges of the first channel steel 22 and the third channel steel 24 are both one side wall of the first channel steel 22 or the third channel steel 24; and the lower flanges of the first channel steel 22 and the third channel steel 24 are both connected to the ends of the second channel steel 23 close to its own slot opening through bolts.

[0064] As can be seen from the above description, this design makes specific modifications to the composition structure of the track 2 to ensure that the track 2 structure composed of the first channel steel 22, the second channel steel 23, and the third channel steel 24 can meet the requirements of subsequent pull-out tests and avoid affecting normal detection work due to structural problems.

[0065] Further, the stiffening rib assembly 21 includes a connecting plate 211 and a supporting plate 212;

[0066] The plane where the connecting plate 211 is located is perpendicular to the plane where the support plate 212 is located, and the connecting plate 211 bisects the support plate 212;

[0067] The inside of the first channel steel 22 or the inside of the third channel steel 24 is connected to the connecting plate 211;

[0068] Horizontal adjusting rod groups 3 are connected to the support plates 212 on both sides in the thickness direction of the connecting plate 211.

[0069] As can be seen from the above description, the design makes specific modifications to the composition structure of the stiffening rib assembly 21, so that the stiffening rib assembly 21 can not only effectively improve the overall strength of the first channel steel 22 and the third channel steel 24, but also provide structural support for the adjustment of the levelness of the track 2 during the assembly process.

[0070] Further, the horizontal adjusting rod group 3 includes a threaded support rod 31, and a leveling nut 32 and a locking nut 33 sleeved on the threaded support rod 31;

[0071] When the horizontal adjusting rod group 3 is connected to the stiffening rib assembly 21, the support plate 212 is fastened between the leveling nut 32 and the locking nut 33.

[0072] As can be seen from the above description, the design makes specific improvements to the composition structure of the horizontal adjusting rod group 3. The staff can adjust the levelness of the track 2 by changing the position of the leveling nut 32 on the threaded support rod 31, and then fasten the adjusted track 2 to the horizontal adjusting rod group 3 through the locking nut 33, so as to prevent the adjusted track 2 from shifting again under the action of external forces and improve the pouring quality of the track 2.

[0073] Further, in the depth direction of the pouring groove 1, connecting members 4 are arranged at intervals on the side walls of the pouring groove 1;

[0074] The connecting members 4 are all connected to the corresponding connecting plates 211.

[0075] Further, the above-mentioned loading device track further includes a reinforcing rib 5;

[0076] The extending direction of the reinforcing rib 5 is parallel to the extending direction of the pouring groove 1;

[0077] The connecting members 4 at the same height are arranged opposite to the reinforcing rib 5.

[0078] Specifically, the reinforcing rib 5 and the connecting members 4 at the same height can be either connected to each other or place the reinforcing rib 5 on one side of the connecting members 4 during subsequent pouring.

[0079] As can be seen from the above description, the design further optimizes the quantity and layout requirements of the connecting members 4, thereby effectively improving the connection force between the track 2 and the casting groove 1. At the same time, a reinforcing rib 5 is connected between the corresponding connecting members 4, so as to further improve the connection effect between the connecting members 4. Furthermore, after the casting of the track 2 is completed, the anti-pulling bearing capacity of the track 2 can be significantly improved to better meet the performance detection requirements of large-capacity fan blades.

[0080] Furthermore, the above-mentioned loading device track further includes a casting layer 6.

[0081] After the track 2 and the casting groove 1 are assembled, the casting layer 6 is filled between the track 2 and the casting groove 1.

[0082] Specifically, the casting layer 6 is made of any commercially available material that can improve the overall strength of the structure after solidification, such as a concrete layer.

[0083] As can be seen from the above description, the casting layer 6 is a medium connecting the track 2 and the casting groove 1. After the casting layer 6 solidifies, the overall strength can be effectively improved. That is, through the connecting members 4, the horizontal adjusting rod group 3 and the stiffening rib assembly 21, the connection strength between the casting layer 6 and the casting groove 1 can be effectively improved. Also, since the track 2 and the casting groove 1 are also connected by the connecting members 4 and the horizontal adjusting rod group 3, when the track 2 is subjected to an upward vertical pulling force, the casting groove 1, the connecting members 4, the horizontal adjusting rod group 3, the stiffening rib assembly 21, the concrete layer and the track 2 can be mutually pulled, so as to achieve the effect of improving the anti-pulling bearing capacity of the track 2.

[0084] The present utility model also provides a fan blade test bench 7, including a base main body 71, a fan blade positioning seat 72, a cable 73, a ground anchoring device 74, and the loading device track according to any one of the above.

[0085] The fan blade positioning seat 72 is arranged on the working surface of the base main body 71.

[0086] The loading device track is embedded in the base main body 71, and the opening of the loading device track faces the working surface of the base main body 71.

[0087] The fan blade positioning seat 72 is arranged at one end in the length direction of the loading device track.

[0088] The ground anchoring device 74 is slidably connected to the loading device track.

[0089] When the fan blade to be detected is connected to the fan blade positioning seat 72, 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 to the ground anchoring device 74 through the cable 73.

[0090] Specifically, a corresponding motor is also provided on the ground anchoring device 74 to release (reduce the tension on the fan blade) and wind up (increase the tension on the fan blade) the cable 73 by the rotation of the motor; and when the main body 71 of the bearing platform is being poured, one end of the connecting member 4 and one end of the threaded support rod 31 are both embedded in the main body 71 of the bearing platform.

[0091] As can be seen from the above description, this design has made specific improvements to the composition structure of the fan blade test bench 7, thereby providing structural support for the fan blade test bench 7 to simulate the actual load-bearing conditions of the fan blade.

[0092] Furthermore, the number of the loading device tracks is at least three;

[0093] In the width direction of the fan blade to be detected, the loading device tracks are arranged at intervals.

[0094] As can be seen from the above description, this design has further improved the composition structure of the fan blade test bench 7. By increasing the loading device tracks, it is convenient for the staff to set the ground anchoring device 74 on different loading device tracks according to actual needs, so that the fan blade test bench 7 of the present utility model can simulate various different stress scenarios, enabling the finally obtained experimental data to truly reflect the performance of the fan blade, and further facilitating the staff to make timely adjustments to the process parameters during the production and manufacturing process to improve the quality of the fan blade.
