[0025] The technical solutions disclosed in various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0026] Please refer to Figures 1 to 4 The embodiment of the present application discloses a testing device 100, which is used to test the mechanical properties of a triangular tower body 200. The triangular tower body 200 includes a first tower column 210, a second tower column 220, and a third tower column 230 arranged in a triangular shape. The first tower column 210, the second tower column 220, and the third tower column 230 form a main frame of the triangular tower body 200. The first tower column 210, the second tower column 220, and the third tower column 230 are connected by a crossbeam. The mechanical properties of the triangular tower body 200 may include its anti-bending performance, anti-torsion performance, etc.

[0027] During the test of the mechanical properties of the triangular tower body 200, the above-mentioned testing device 100 is mainly used to realize the structural interconnection between the testing machine and the triangular tower body 200, and to transmit the pressure, torque, etc. applied by the testing machine to the triangular tower body 200. Figure 1 and Figure 2 As shown, the test device 100 may specifically include a first loading part 110 and a second loading part 120. The first loading part 110 includes a loading body 111, a first connecting structure 112 and a second connecting structure 113. The loading body 111 is a main load-bearing component. The first connecting structure 112 and the second connecting structure 113 are spaced apart from the loading body 111. The first connecting structure 112 may be connected to the first tower column 210, and the second connecting structure 113 may be connected to the second tower column 220. The first connecting structure 112 and the second connecting structure 113 may include mounting holes, mounting buckles and other structures. Correspondingly, the first connecting structure 112 and the first tower column 210 may be connected in a bolted manner, a clamped manner, etc., and the second connecting structure 113 and the second tower column 220 may also be connected in a bolted manner, a clamped manner, etc.

[0028] The first loading part 110 can realize the structural connection between the first tower column 210 and the second tower column 220. For the third tower column 230, the second loading part 120 can be used for connection. Specifically, the second loading part 120 has a first end and a second end opposite to each other. The first end of the second loading part 120 is connected to the loading body 111 of the first loading part 110, and the specific connection method can be bolt connection, clamping, etc.; the second end of the second loading part 120 is connected to the third tower column 230, and the specific connection method can be bolt connection, clamping, etc. The first loading part 110 and the second loading part 120 can realize the structural interconnection between the first tower column 210, the second tower column 220 and the third tower column 230.

[0029] It should be noted that the connection direction between the first end and the second end of the second loading part 120 is defined as the first direction 101. Along the first direction 101, the projection of the second loading part 120 on the loading body 111 is located between the first connecting structure 112 and the second connecting structure 113, so that the second loading part 120 can pass through the area enclosed by the triangular tower body 200 and be connected to the third tower column 230, thereby improving the rationality of the layout of the testing device 100 and the utilization rate of the internal space of the triangular tower body 200.

[0030] At least one of the loading body 111 and the second loading part 120 can be used to be connected to a testing machine, and the testing machine can be an anti-torsion testing machine, an anti-bending testing machine, etc. Exemplarily, when the anti-torsion performance of the triangular tower body 200 is tested by an anti-torsion testing machine, the anti-torsion testing machine can be connected to the loading body 111; when the anti-bending performance of the triangular tower body 200 is tested by an anti-bending testing machine, the anti-bending testing machine can be connected to both ends of the loading body 111 respectively, or the anti-bending testing machine can be connected to the second loading part 120.

[0031] As described above, a test device 100 disclosed in an embodiment of the present application improves the related art. The disclosed test device 100 includes a first loading part 110 and a second loading part 120. The first loading part 110 includes a loading body 111, a first connecting structure 112 and a second connecting structure 113. The first connecting structure 112 and the second connecting structure 113 are arranged at intervals on the loading body 111. The first connecting structure 112 is used to connect with the first tower column 210, and the second connecting structure 113 is used to connect with the second tower column 220. The second loading part 120 has a first end and a second end opposite to each other. The first end is connected to the loading body 111. Along the connecting direction of the first end and the second end, the projection of the second loading part 120 on the loading body 111 is located between the first connecting structure 112 and the second connecting structure 113, and the second end is used to connect with the third tower column 230. The testing machine can be connected to at least one of the loading body 111 and the second loading part 120, so that the mechanical properties of the triangular tower body 200 can be tested by the above-mentioned testing device 100.

[0032] For triangular tower bodies 200 of different specifications, the spacing between the first tower column 210 and the second tower column 220 is also different. In order to enable the testing device 100 to adapt to triangular tower bodies 200 of different specifications, such as Figures 1 to 3 As shown, the connection direction of the first connection structure 112 and the second connection structure 113 is defined as the second direction 102, and the first connection structure 112 may include a first strip hole 1121, which is arranged on the loading body 111, and the first strip hole 1121 is extended along the second direction 102. Bolt holes may be arranged on the first tower column 210, and the first tower column 210 and the loading body 111 may be assembled by sequentially passing bolts through the bolt holes on the first tower column 210 and the first strip hole 1121 on the loading body 111. When the interval distance between the first tower column 210 and the second tower column 220 changes, the locking position of the first tower column 210 on the first strip hole 1121 may be adjusted, thereby improving the adaptability range of the test device 100.

[0033] like Figures 1 to 3As shown, the second connection structure 113 may include a second strip hole 1131, which is arranged on the loading body 111, and the second strip hole 1131 is arranged at intervals from the first strip hole 1121, and the second strip hole 1131 is extended along the second direction 102. Bolt holes may be arranged on the second tower column 220, and the second tower column 220 and the loading body 111 may be assembled by sequentially passing bolts through the bolt holes on the second tower column 220 and the second strip hole 1131 on the loading body 111. When the interval distance between the first tower column 210 and the second tower column 220 changes, the locking position of the second tower column 220 on the second strip hole 1131 may be adjusted, thereby further improving the adaptability range of the testing device 100.

[0034] It should be added that, since the first tower column 210 needs to be installed through the first strip hole 1121 and the second tower column 220 needs to be installed through the second strip hole 1131, in order to improve the reliability of the connection between the first tower column 210 and the second tower column 220 and the loading body 111, the number of the first strip holes 1121 and the second strip holes 1131 can be two or more, and correspondingly, the number of bolt holes opened in the first tower column 210 and the second tower column 220 and the number of bolts used match the number of the above-mentioned strip holes.

[0035] To facilitate the assembly of the loading body 111 and the second loading part 120, as shown in FIG. Figures 1 to 4 As shown, the loading body 111 may include a support member 1111 and an extension member 1112, a first connection structure 112 and a second connection structure 113 are arranged on the support member 1111 at intervals, the extension member 1112 is connected to the support member 1111, and the connection method of the extension member 1112 and the support member 1111 may include welding, clamping, bolting, etc., and the extension member 1112 extends in the first direction 101 in a direction away from the support member 1111, and the extension member 1112 is located between the first connection structure 112 and the second connection structure 113. The first end of the second loading part 120 is connected to the extension member 1112, and the specific connection method may include clamping, bolting, etc. In order to improve the assembly strength of the second loading part 120 and the loading body 111, when the second loading part 120 is connected to the extension member 1112, there may be an overlapping area between the two, so that mutual support can be achieved.

[0036] When testing the triangular tower bodies 200 of different specifications, it is considered that when the interval between the first tower column 210 and the second tower column 220 changes, the distance between the third tower column 230 and the loading body 111 will also change accordingly. Figures 1 to 4As shown, the second loading part 120 may be slidably connected to the extension piece 1112 , and the second loading part 120 may slide relative to the extension piece 1112 along the first direction 101 , thereby being able to adapt to the change in the distance between the third tower column 230 and the loading body 111 .

[0037] In an optional embodiment of the present application, Figures 1 to 4 As shown, the extension piece 1112 is provided with a third strip hole 1113, and the third strip hole 1113 is extended along the first direction 101. The area near the first end of the second loading part 120 is provided with a first connecting hole 121. The third strip hole 1113 and the first connecting hole 121 can be connected by fasteners such as bolts, so that the second loading part 120 can be adjusted to the extension piece 1112. When the bolt is not locked, the second loading part 120 and the extension piece 1112 can slide relative to each other along the first direction 101, so that the second end of the second loading part 120 can be stably connected to the third tower body. After the position adjustment is completed, the bolt can be locked to make the second loading part 120 and the extension piece 1112 relatively fixed.

[0038] like Figures 1 to 3 As shown, a reinforcing rib 1114 is provided at the connection between the extension member 1112 and the support member 1111. The reinforcing rib 1114 can be connected to the extension member 1112 and the support member 1111 respectively by welding, riveting, etc., so as to improve the connection strength between the extension member 1112 and the support member 1111.

[0039] like Figures 1 to 3 As shown, the extension member 1112 may include a first rib plate 1112a and a second rib plate 1112b, and the first rib plate 1112a and the second rib plate 1112b are respectively connected to the support member 1111, and the specific connection method may include welding, clamping, bolt connection, etc. The first rib plate 1112a and the second rib plate 1112b are parallel to each other, so that an installation space is formed between the first rib plate 1112a and the second rib plate 1112b, and the first end of the second loading part 120 can extend into the installation space. When the second loading part 120 slides relative to the extension member 1112, the first rib plate 1112a and the second rib plate 1112b can guide the second loading part 120 to improve the stability of the second loading part 120 during the sliding process. In addition, the first end of the second loading part 120 extends into the installation space and overlaps with the first rib plate 1112a and the second rib plate 1112b, respectively, which can improve the reliability of assembly to a certain extent.

[0040] like Figures 1 to 4As shown, the testing device 100 is connected to the third column 230 via the second loading part 120. To improve the reliability of the connection of the third column 230, the testing device 100 may include at least two second loading parts 120, and the at least two second loading parts 120 may be parallel to each other.

[0041] like Figures 1 to 4 As shown, since the third tower column 230 is made of 60° angle steel material, and the second end of the second loading part 120 is in contact with the inner side of the third tower column 230 (the inner side of the bending angle steel) when connected to the third tower column 230, in order to improve the stability of the connection between the second end of the second loading part 120 and the third tower column 230, a first support plate 122 and a second support plate 123 can be set at the second end, and the first support plate 122 and the second support plate 123 are connected at a preset angle, and the preset angle can be 50°-70°. With the above design, the first support plate 122 and the second support plate 123 can be respectively supported and matched with the surface of the third tower column 230, thereby improving the stability of the assembly.

[0042] In addition, if Figure 4 As shown, a second connecting hole 124 may be opened in at least one of the first support plate 122 and the second support plate 123, and a bolt hole may be opened on the third tower column 230. Bolts and other fasteners pass through the second connecting hole 124 and the bolt holes on the third tower column 230 in sequence, so as to further fix the second loading part 120 and the third tower column 230.

[0043] The first tower column 210 , the second tower column 220 and the third tower column 230 of the triangular tower body 200 may be arranged in an equilateral triangle. Correspondingly, the first direction 101 may be perpendicular to the second direction 102 , and the extension piece 1112 may be located at the midpoint of the line connecting the first connecting structure 112 and the second connecting structure 113 .

[0044] When the test machine is connected to the support 1111, a third connection hole 1115 may be provided on the support 1111, and the test machine may be assembled with the third connection hole 1115 by means of bolts. The number of test machines may be one, two, or more than two. For example, the number of test machines is two, and the two test machines are respectively connected to the two ends of the support 1111. Correspondingly, the two ends of the support 1111 are respectively provided with a third connection hole 1115.

[0045] In an optional embodiment of the present application, the loading body 111 and the second loading part 120 can be at least one or a combination of channel steel parts, I-beam parts and angle steel parts. The use of the above-mentioned steel profiles can improve the structural strength of the test device 100, thereby avoiding deformation and damage of the test device 100 due to heavy load during the test process. At the same time, it is also beneficial to improve the accuracy of the test results.

[0046] The embodiment of the present application also discloses a testing system, which may include a testing machine and the above-mentioned testing device 100. The testing machine may be connected to the triangular tower body 200 through the testing device 100 to test the mechanical properties of the triangular tower body 200, such as anti-bending performance and anti-torsion performance.

The second loading part 120 has a first end and a second end opposite to each other. The first end is connected to the loading body 111. Along the connecting direction of the first end and the second end, the projection of the second loading part 120 on the loading body 111 is located between the first connecting structure 112 and the second connecting structure 113, and the second end is used to connect with the third tower column 230.
