摘要
针对长输油气管道施工和抢维修过程中,施工现场"碰死口"下短管工序对钢管切割和管端坡口的需求,研制一套机械分瓣式钢管切割机设备。该切割机使用安全的冷切割工艺,钢管母材的性能不会改变。采用分瓣式联接结构,通过夹持机构将两瓣固定在钢管外壁上,通过刀盘的旋转和刀具的自动进给,能够同时实现钢管的切割及管端坡口的功能。现场实验情况表明:该切割机整体机械结构设计合理,安装拆卸方便,切割效率高,适合管道抢维修断管作业,提高了管道抢修效率和质量,降低了劳动强度和安全风险。
In order to meet the requirement of pipe cutting and beveling during pipeline connecting on the construciton site,especially under the condition of long gas and oil pipelines construction and rush repair,the mechanical split-type pipe cutting machine is developed.This cutting machine can keep the pipe＇s material properties unchanged with cold cutting technology.The pipe cutting and beveling functions can be performed by means of the cutter head rotation,the cutter automatic feeding and the special split-type joint structure,which uses a clamping mchanism to fix the two setions onto the pipe outside.Field experments show that this kind of cutting machine,which has a reasonable mechanical structure design and a high cutting efficiency,can be disassembled easily,suitable for pipe cutting of rush repsir,which not only improves pipeline rush repair efficiency and quality,but also reduces labor intensity and risks.
