活动工作台是钻探施工中塔上作业的载人升降工具,对减轻工人劳动强度,提高劳动效率,起到了积极的作用.但使用中也出现了一些问题,在缺乏检查和操作不当的情况下,常发生跑台、坠台,造成伤亡事故.我们经过半年多的努力,参考煤矿罐笼防坠器的原理,试制了EDY型活动工作台防坠器.经试验和现场几个月的使用,性能可靠.EDY型防坠器由压缩弹簧、中心拉杆、杠打和卡瓦等组成(如图).当工作台提引钢丝绳折断时,压缩弹簧伸张,中心拉杆下行,带动平衡板与连接板,使杠杆绕各自的支点 The active workbench is a manned lifting tool used for tower work in the drilling construction, which plays a positive role in alleviating the labor intensity and improving the labor efficiency of the workers, but some problems have appeared during the use. In the absence of inspection and improper operation , Often run the stage, fall Taiwan, causing casualties.We have more than six months of hard work, reference to the principle of coal mine cage anti-dropping device, trial production EDY-type activity table anti-dropping device.After several months of testing and site use, Reliable performance .EDY-type fall arrester by the compression spring, the center rod, bar and slip and so on. (Figure). When the table to lift wire rope breakage, the compression spring extends, the center rod down to bring balance board and connecting plate , So that the lever around their fulcrum
