With the continuous action of the load, the support column 11 continues to descend, driving the sleeve plate 14 to rotate under the guidance and constraint of the installation slot 13 and the installation slot two 16. When the sleeve plate gradually becomes horizontal, the two ends of the sleeve plate push the two groups of sliders 6 arranged symmetrically to slide towards each other along the sliding groove 5. The sliders compress the springs 8 in the movement process, forming a secondary buffering structure to further attenuate the vibration energy. At the same time, the self-locking universal wheel 17 at the bottom of the device can be flexibly switched between the fixed mode and the moving mode according to the operation requirements, which not only ensures the positioning stability of the device, but also improves the site adaptability. In summary, the device can play a multi-stage damping role through the combined arrangement of the first-stage damping assembly 3 and the second-stage damping assembly 4, overcoming the shortcomings that when the to-be-lifted goods is quickly placed on the bearing platform 15, the spring assembly lacks pre-tightening buffering, causing the device to produce instantaneous downward impact, directly affecting the overall stability.
