摘要
针对卷扬式擦窗机吊船的防坠安全问题,设计了棘轮棘爪式防坠安全装置。研究装置的关键部件棘轮棘爪,并建立了棘轮棘爪动力学数学模型,得到了影响棘轮棘爪式防坠安全装置制动性能的各个参数的关系;通过ADAMS对装置的制动过程进行仿真计算,获得装置的制动性能曲线;搭建试验平台,对防坠安全装置进行试验验证,结果试验数据与仿真数据基本一致,证明仿真结果的准确性,并且该防坠安全装置制动迅速且可靠;以棘爪长度XDE为设计变量,通过ADAMS进行优化设计,仿真结果表明,防坠安全装置棘爪的最优长度为115mm。
In view of the safety problem of the winch type Building maintenance unit,the ratchet and pawl type fall arrest device is designed.The key part of the research device is ratchet and pawl and establish dynamic mathematical model of ratchet.The relationship between the parameters that affect the braking performance of the ratchet and pawl type anti falling safety device is obtained;ADAMS is used to simulate the braking process of the device,and the braking performance curve of the device is obtained,and the test platform is built to test and verify the fall arrest device.The results show that the test data are basically consistent with the simulation data,which proves the accuracy of the simulation results.Moreover the fall arrest device braking is fast and reliable;Taking the length of the pawl XDEas the design variable,the optimal design is carried out by ADAMS.The simulation results show that the optimal length of the pawl of the fall arrest device is 115mm.
