目前在坠落试验和冲击试验中常用的脱开方式有两种:一是通电控制电磁铁吸附铁制重物脱开方式,它受外界停电影响,容易发生停电坠落事故;二是采用液压缸控制的快速脱开装置,它需要有固定泵站,连接的高压油管需要在起升范围内来回移动,释放脱开时还伴随振动,油管容易在接头处产生泄露,也存在隐患。本文研究的是一种机械式快速脱开装置,使用时用手动或电动控制,通过驱动轮、传动轴、齿轮操纵丝杠打开或锁紧夹钳,通过施加力将夹
Currently in the fall test and impact test commonly used in two ways to get out: First, control electromagnet electromagnet attraction heavy metal off the way, it is affected by external power outages, prone to power failure crashes accident; the second is the use of hydraulic cylinder control Fast disconnect device, which requires a fixed pumping station, connected to the high-pressure tubing need to move back and forth within the lifting range, the release is also accompanied by vibration, the tubing easily leak at the joints, there are hidden dangers. In this paper, a mechanical quick disconnect device is used, which is manually or electrically controlled when used, and the clamp is opened or locked by the driving wheel, the transmission shaft and the gear control screw, and the clamp
