摘要:
起升油缸是随快移快装钻机一起设计开发的,专门用来起升下放井架和底座,实现钻机的快移快装理念,是快移快装钻机的重要组成部件。从开发到批量生产投入使用以来,起升油缸发生了多起事故,主要集中在上部油缸头折断这种损坏方式,严重影响了快移快装钻机的正常使用。从起升油缸结构和功用着手,探讨如何改善起升油缸的承载环境,分析油缸头事故原因,提出了相应的预防措施。
The lifting cylinder was designed together with the quick moving and quick making-up drilling rigs, which was especially used for lifting and lowering down the derricks and substructures, and it was the key component for the quick transferring and making-up of the drilling rigs. From its development to the batch production and to its application, many accidents were appeared in the lifting cylinder, and the failures were breakings concentrated in the upper cylinder head, which was severely affected the normal application of the rigs. From the aspects of its structure and functions of the lifting cylinders, how to improve the loading environment of the lifting cylinders is discussed and the reason of its accidents is analyzed, and corresponding measures are proposed for preventing the accidents.
