One end of the cylinder 21 is hinged to the supporting ear piece 12, and the other end is hinged to the shift rod 23. The shift rod 23 is fixedly connected to the driving gear 22. The cylinder 21 drives the driving gear 22 to rotate by pushing the lower end of the shift rod 23, thereby driving the entire device to operate.

[0021] The shaking part 30 includes a follower gear 31, a three-link rod 32, an outer connecting rod 33, an inner connecting rod 34 and a support plate 35. The follower gear 31 is meshed with the driving gear 22 for transmission. The three-link rod 32 is fixedly connected to the follower gear 31. The middle part of the three-link rod 32 is hinged to the outer connecting rod 33. The other end of the outer connecting rod 33 is hinged to the outer hinge support 422 of the outer arc support 42. The lower end of the three-link rod 32 is hinged to the inner connecting rod 34. The other end of the inner connecting rod 34 is hinged to the side hinge support 352 of the support plate 35. The support plate 35 is installed on the inner arc support 41. The bottom of the support plate 35 has an upper hinge support 351. The upper hinge support 351 is docked with the lower hinge support 412 to realize the installation of the support plate 35. The front side of the support plate 35 is connected downwardly to the side hinge support 352.

[0022] The following part 40 includes an inner arc support 41, an outer arc support 42, a bracket 43 and a roller 44. The inner arc support 41 is sleeved and installed on the inner ring of the outer arc support 42.

[0024] The working principle of the present application is that: the transformer product to be tested is fixedly installed on the support plate 35, the air cylinder 21 of the driving part 20 drives the push rod 23 to swing at a certain frequency and amplitude, the push rod 23 drives the driving gear 22 to rotate, the driving gear 22 drives the driven gear 31 to rotate, the rotation of the driven gear 31 drives the three-link rod 32 to swing, the swing of the three-link rod 32 forms two branches, the first branch drives the whole driven part 40 to move left and right on the guide rail 11 from the middle of the three-link rod 32 through the outer connecting rod 33, forming a vibration source, the second branch moves the support plate 35 from the lower end of the three-link rod 32 through the inner connecting rod 34, the movement of the support plate 35 acting on the inner arc support 41 on the outer arc support 42 is to make the inner arc support 41 swing on the outer arc support 42, superimposed with the overall movement of the driven part 40 driven by the outer connecting rod 33, finally the movement acting on the support plate 35 is the sway movement, and finally the transformer product sway test is formed. By adjusting the pushing amplitude and frequency of the air cylinder 21 to the push rod 23, the amplitude and frequency of the transformer product sway test can be adjusted. If necessary, the length difference of the outer connecting rod 33 and the inner connecting rod 34 can be adjusted appropriately, and the sway parameters can be further adjusted.

[0025] The above examples mainly illustrate the transformer sway test platform of the present application. Although only limited examples and technical features are described, those skilled in the art should understand that the present application can be implemented in many other forms without deviating from its main purpose and scope. Therefore, the examples shown are considered illustrative rather than limiting, and the present application can encompass various modifications and alternatives without departing from the spirit and scope of the present application defined by the appended claims.
