【摘要】：研制开发一种具有自主知识产权的立体停车场升降系统安全装置,当停车场升降系统出现故障坠落时产生巨大能量,带有能量液体通过主进油口到下内耗腔,一小部分通过内外腔连接孔进入上稳压腔,绝大部分通过下内耗腔到主出油口流出。由于下内耗腔有液体流动压力会急剧下降,而上稳压腔无液体流动压力不变,上稳压腔的压力大于下内耗腔的压力,浮动压力平衡侧板克服弹性支承下移使下内耗腔间隙减小。通过计算流进能量吸收装置所损失的能量与流量线性增大,与浮动压力平衡侧板和能量吸收壳体底部的间隙减小成三次方数量级增大,能量损失快速转换为热能,进而实现随意调整冲击能量吸收值的大小,做到能量的合理匹配目的。
[Abstract]:Research and development of a safety device for a three-dimensional parking lift system with independent intellectual property rights. When the parking lot lift system fails and falls, it produces huge energy, with the energy liquid passing through the main oil inlet to the internal friction chamber. A small part enters the upper pressure stabilizer cavity through the inner and outer cavity connection holes, and most of them flow out through the lower internal friction cavity to the main outlet. The pressure of the upper cavity is larger than that of the lower cavity, and the pressure of the upper cavity is larger than the pressure of the lower cavity. The floating pressure balance side plate overcomes the downward movement of elastic support and reduces the gap of the lower friction cavity. By calculating the linear increase of the energy and flow rate lost by the energy absorption device, the gap with the floating pressure balance side plate and the bottom of the energy absorption shell decreases to the third order of magnitude, and the energy loss is quickly converted to heat energy. Then the impact energy absorption value can be adjusted at will to achieve a reasonable energy matching purpose.
