Abstract
The invention relates to a high-power hydraulic emergency energy absorbing device and method of a parking tower. When energy liquid enters a main oil inlet to reach a lower internal friction cavity, a fraction of the energy liquid enters an upper constant-pressure cavity through an internal-external cavity connecting hole, and most of the energy liquid passes the lower internal friction cavity to be discharged from a main oil outlet. When high-energy liquid quickly flows into the lower internal friction cavity, pressure of the lower internal friction cavity drops sharply, and no liquid flows in the upper constant-pressure cavity, so that pressure is constant; and when the pressure of the upper constant-pressure cavity is higher than that of the lower internal friction cavity, elastic supports are prevented from moving downwards by a floating pressure-balancing side plate so as to decrease the size of a lower internal friction cavity gap, and accordingly wasted energy of the device is increased by cubic order of magnitude of the lower internal friction cavity gap, and all energy loss is converted into heat energy. The device and method has the advantages that absorbed energy is increased with external energy; the device is of a plate type structure, thereby being good in heat dissipation performance; the device is not easy to block and high in anti-pollution performance; the absorbed energy is stable and cannot rebound; and safe protection effect on faults of a parking tower lifting system is achieved.
