在作垂直冲击试验过程中 ,一般抓起并可放开冲击重物的快速脱开装置常用电磁铁来完成 ,通过通、断电来控制电磁铁吸附或脱开铁制重物。但常由于断电等意外而造成事故。作者发明了一种由气 (液压 )缸控制的安全快速脱开装置 ,很好地解决了快速脱开装置的安全性问题
In the vertical impact test process, the general grab and can release the rapid release of the impact of heavy objects commonly used electromagnet to complete, through the power to control the electromagnet adsorption or removal of heavy iron. But often due to accidents such as power outages and accidents. The inventor invented a safe and quick release device controlled by a gas (hydraulic) cylinder, which solves the problem of safety of the quick release device
