[0024] Example

[0025] like Figures 1-5 As shown, a photovoltaic tracking bracket testing fixture includes a base 1. Multiple sets of first threaded holes 2 for mounting test pieces 3 are formed on the base 1. An H-shaped fixing frame 4 is mounted on the other end of the base 1 through the first threaded holes 2. The H-shaped fixing frame 4 consists of a vertical support beam 5 and a horizontal support beam 6. The vertical support beam 5 is detachably mounted on the top of the base 1, and the vertical support beam 5 is arranged in pairs. The horizontal support beam 6 is detachably mounted on the vertical support beam. A hanging ear plate 7 is detachably connected to the H-shaped fixing frame 4. An electric hoist 8 is suspended from the hanging ear plate 7. A tension gauge 9 is mounted on the electric hoist 8 via a chain. The other end of the tension gauge 9 is connected to the test piece 3 via a connector 10.

[0026] The bottom of the test piece 3 is bolted to the top of the first threaded hole group 2 at different positions on the base 1. The H-type fixing bracket 4 can also be fixedly installed at different positions through the first threaded hole group 2. The corresponding hanging ear plate 7 can be bolted to different positions on the H-type fixing bracket 4 as needed. Power or load is provided to the tension gauge 9 through the electric hoist 8 and the iron chain. The other end of the tension gauge 9 transmits the power or load to the test piece through the connector 10. This realizes the testing of different types of test pieces 3 under different loads and different force directions. At the same time, it is convenient to adjust, easy to replace or test different test pieces 3 at the same time, and improves the testing efficiency.

[0027] Accordingly, test component 3 can specifically be components such as the reducer, main beam, column, and bearing seat in the photovoltaic tracking bracket.

[0028] In some alternative embodiments, the vertical support beam 5 and the horizontal support beam 6 are provided with several sets of second threaded holes 11. The vertical support beam 5 and the horizontal support beam 6 are connected by bolts. The second threaded hole sets 11 are used to cooperate with the bolts to install the horizontal support beam 6 at different heights on the vertical support beam 5.

[0029] In some alternative embodiments, the vertical support beam 5 is set as a rectangular tube, and the horizontal support beam 6 is set as an H-beam. The vertical support beam 5 is provided with a plurality of first through holes 12 evenly in the vertical direction.

[0030] Furthermore, a first L-shaped plate 13 is installed on the first through hole 12, a second through hole 14 is provided on the first L-shaped plate 13, a second L-shaped plate 15 is provided on the second through hole 14, and a bend is provided on the top of the second L-shaped plate 15.

[0031] More specifically, the top of the second L-shaped plate 15 is set on the top of the transverse support beam 6, and the corner is suspended from the top of the transverse support beam 6 of the H-shaped steel structure.

[0032] By inserting the first L-shaped plate 13 into the first through holes 12 at different heights on the vertical support beam 5, and by inserting the second L-shaped plate 15 into the second through hole 14 and suspending the corner part on the top of the horizontal support beam 6, the horizontal support beam 6 can be fixed and limited. Compared with the bolt connection method, it is more convenient to adjust the height of the horizontal support beam 6.

[0033] In some alternative embodiments, the connector 10 is configured as one of a steel strand, a steel pipe, a V-bar, or a chain. For example, when testing with a single-point load, the connector 10 is configured as a steel strand, a steel pipe, or a chain; when testing with a two-end load, the connector 10 is configured as... Figure 1 The aforementioned V-shaped rod.

[0034] like Figure 1As shown, when performing load testing at the connection of the photovoltaic main beam, the photovoltaic main beam is installed using the columns, bearings, and bearing seats in the existing photovoltaic bracket. The two ends of the test piece 3 (the connection of the photovoltaic main beam) are connected by the connector 10. The other end of the connector 10 is connected to the tension gauge 9. The tension gauge 9 is connected to the electric hoist 8 by the iron chain. The other end of the electric hoist 8 is hung on the hanging ear plate 7. Power or load is provided to the tension gauge 9 through the electric hoist 8 and the iron chain. The other end of the tension gauge 9 transmits the power or load to the test piece through the connector 10. The tension gauge 9 measures the load size, and the destructive load is determined by visual inspection or by measuring the deformation.

[0035] like Figure 2 As shown, when performing load tests on the column, the column is connected to the tension gauge 9 via the steel pipe connector 10.

[0036] like Figure 3-4 As shown, when testing an existing damper support, a plate-shaped load transfer component is installed on top of the damper support, and the damper support is connected to the tension gauge 9 via connector 10.

[0037] The above are preferred embodiments of the present invention. The basic principles, main features, and advantages of the present invention have been shown and described above. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are only illustrative of the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope thereof. All such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
