近年来,随着施工企业安全生产管理力度日渐加强,作为管道建设必不可少的机械设备——吊管机的使用安全越来越受到人们的重视。针对一些半机械式吊管机未配备力矩限制器等安全防护装置的问题,利用吊管机吊装系统中的液压部分,通过加装电磁换向阀、溢流阀和机械式换向阀的方式,为半机械式吊管机加装力矩限制器,有效地解决了吊管机的安全限位问题。经验证,改造后的吊管机满足安全使用要求,效果良好。
In recent years, with the safety management of construction enterprises increasingly strengthened, as the pipeline construction essential machinery and equipment - the safety of the pipelayer more and more attention. For some semi-mechanical pipelayer is not equipped with torque limiter and other safety devices, the use of pipelayer hoisting system in the hydraulic part, through the installation of electromagnetic reversing valve, relief valve and mechanical valve , For semi-mechanical pipelayer installed torque limiter, effectively solve the safety limit of pipelayer. Proved that the modified pipelayer to meet the safety requirements, the effect is good.
