[0029] Please refer to Figure 1 and Figure 2, multiple angular gearboxes 6 are provided with auxiliary components on the outside, and the auxiliary components include multiple universal joint shafts 7. Two adjacent angular gearboxes 6 are installed and connected through the universal joint shaft 7, and one end of the multiple angular gearboxes 6 and the extended shafts of the multiple hydraulic vibration hammers 4 are connected through couplings 8. The multiple vibration platform main beams 2 and the multiple vibration platform sub-beams 3 are all installed and connected with square pins 9 and bolts 2. The vibration platform main beam 2 and the vibration platform sub-beam 3 are installed and connected with square pins 9 and bolts 2, which can meet the vertical shear and lateral connection requirements;

[0030] See also Figure 1 , a plurality of vibration-damping rubbers 10 are fixedly connected to the top of the steel plate 1. The plurality of vibration-damping rubbers 10 are evenly distributed with the center line of the steel plate 1 as the axis. The plurality of vibration-damping rubbers 10 are respectively located at the bottom of the plurality of vibration platform main beams 2. The diameter of the plurality of vibration-damping rubbers 10 is set to 1.2 meters. By setting up a plurality of vibration-damping rubbers 10, it can effectively absorb excess vibration and ensure the smooth operation of the vibration hammer group;

[0031] See also Figure 1 A plurality of oil pipes 11 are installed between the plurality of hydraulic vibration hammers 4. The plurality of oil pipes 11 are all made of flexible materials. Because the plurality of oil pipes 11 are all made of flexible materials, the use effect of the oil pipes 11 can be better.

[0032] The implementation principle of this embodiment is as follows: when in use, the test site is first paved and leveled, and then a steel plate 1 is laid on the leveled site, and then a plurality of vibration-damping rubbers 10 are evenly placed on the steel plate 1. After the placement of the plurality of vibration-damping rubbers 10 is completed, the plurality of vibration platform main beams 2 and the plurality of vibration platform sub-beams 3 can be placed on the vibration-damping rubbers 10 for testing.

Under the action of the same exciting force, the interference between the main beams is not obvious. The model is simplified to the main beam driving the movement of the sub-beam that is only affected by gravity. Therefore, the stress value of the sub-beam and the connecting parts between the sub-beam are small. In the analysis results, it is not the area where the stress maximum value is located, and the strength is also sufficient.
