[0002] A boiler is an energy conversion device, and the energy input into the boiler includes chemical energy in fuel and electric energy. The boiler outputs steam, high-temperature water or organic heat carriers with certain heat energy. Generally, the boiler has a large volume, and the boiler generates certain vibration in the use process. Therefore, in order to better protect the use of the boiler, a shock absorption device is usually used at the bottom of the boiler to reduce the damage of the vibration to the boiler itself.

[0003] From the basic direction, the boiler vibration includes vertical vibration and horizontal vibration. When the inertial force generated by the vibration acts on the boiler, the stress inside the boiler changes.

At present, the shock absorption device for the boiler usually installs vertical shock absorption springs at the bottom of the boiler to play the effect of boiler shock absorption. However, this kind of shock absorption device can only provide the effect of shock absorption in the vertical direction and cannot work in the horizontal direction. SUMMARY
