Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0024] Reference Figures 1-2 An embodiment provided by the present application: a kind of simulation microseismic environment vibration test platform, including vibration table 1, vibration table 1 top is fixedly connected with multiple fixed columns 2, fixed column 2 top is provided with test table 3, test table 3 upper surface is fixedly connected with multiple slide rails 4, the upper surface of slide rail 4 is slidably connected with multiple sliding tables 5, the upper surface of sliding table 5 is provided with fixed assembly, fixed assembly includes multiple support tables 6, multiple support tables 6 are fixedly connected on the upper surface of each sliding table 5, support table 6 bottom is fixedly connected with electric push rod 7, the output end of electric push rod 7 is fixedly connected with push table 8, push table 8 is fixedly connected with sliding shaft 9 inside, sliding shaft 9 can slide in chute 12, so that push table 8 can be accurately adjusted position under the drive of electric push rod 7, the upper surface of support table 6 is fixedly connected with fixed frame 10, fixed frame 10 is rotatably connected with rotating frame 11 inside, rotating frame 11 can rotate in fixed frame 10, by controlling the angle of rotating frame 11, the direction of support table 6 can be accurately adjusted, to ensure that test article keeps correct positioning during vibration, rotating frame 11 is internally provided with chute 12, sliding shaft 9 is slidably connected in chute 12, the sliding fit of sliding shaft 9 makes the rotation of rotating frame 11 and the movement of support table 6 consistent, ensures the stability of article fixation, pressing plate 13 is fixedly connected on the side wall of rotating frame 11, and the firm fixation of article is realized by the contact of pressing plate 13 with the article, to prevent displacement or looseness of the article during vibration, so as to ensure the accuracy and consistency of test results, test table 3 side wall is provided with connecting assembly.

[0025] Specifically, first, when the to-be-tested object needs to be fixed, the support table 6 is accurately positioned at the appropriate position by sliding the sliding table 5, ensuring that the to-be-tested object can be stably placed on the platform. After the electric push rod 7 is started, the push table 8 is pushed, and then the sliding shaft 9 inside the push table 8 smoothly slides inside the inclined chute 12, so that the rotating frame 11 is forced to rotate under the action of the fixing frame 10 and changes its angle. The change of the angle of the rotating frame 11 drives the pressing plate 13 on the side wall to uniformly press the to-be-tested object, thereby firmly fixing the object on the platform, preventing test result errors caused by movement or loosening of the object during testing, ensuring the stability of the object during testing, and effectively ensuring the consistency and accuracy of the data.

[0026] With reference to Figure 3 The connecting assembly includes a plurality of side tables 14 fixedly connected to the side wall of the test table 3. Each side table 14 is slidably connected with a connecting column 15 inside. The bottom of each connecting column 15 is fixedly connected with a bottom column 16. The bottom column 16 is provided with a sliding groove 17 inside. The bottom column 16 is provided with a plurality of clamping beads 23 inside. The clamping beads 23 are slidably connected inside the sliding groove 17. The connecting column 15 is slidably connected with a connecting shaft 18 inside. The connecting shaft 18 is fixedly connected with a pressing plate 19 at the top end. The connecting shaft 18 is fixedly connected with a push plate 20 at the bottom end. The push plate 20 is fixedly connected with a connecting piece 21 on the lower surface. The connecting piece 21 is fixedly connected with a push shaft 22 on the outer wall. The connecting shaft 18 is provided with a spring 24 on the outer wall. One end of the spring 24 is fixedly connected to the upper surface of the push plate 20. The other end of the spring 24 is fixedly connected inside the connecting column 15.

[0027] Specifically, when the vibration table 1 needs to be maintained, first pull the pressing plate 19. The generated force makes the connecting shaft 18 slide inside the connecting column 15, thereby driving the bottom push plate 20 and the connecting piece 21 to displace upward. In this process, the push shaft 22 is displaced and no longer limits the clamping beads 23, allowing the clamping beads 23 to smoothly slide in the sliding groove 17. With the sliding of the clamping beads 23, the connecting column 15 gradually separates from the side table 14, thereby releasing the fixing relationship between the side table 14 and the fixing column 2. At this time, through the action of the connecting shaft 18, the structure can be quickly reset, ensuring that the test table 3 can be conveniently disassembled and maintained. This process can effectively reduce the time of equipment switching, improve the maintenance efficiency of the equipment, and thereby improve the overall test efficiency.
