本文针对抽油机在调冲程更换曲柄销子过程中,常常由于连杆和曲柄之间销子长时间不动,造成锈死,致使销子和曲柄成为一体。每次更换曲柄销子都需消耗大量工作量和时间,造成施工时间过长,易造成躺井的问题,提出了研制抽油机曲柄销子更换装置,可以缩短更换曲柄销子所需时间,提高工作效率;减少停井施工时间,避免出砂或稠油井躺井;装置结构简单、操作安全方便。
In this paper, the pumping unit in the transfer stroke replacement crankpin process, often because of the link between the crank and the pin for a long time does not move, resulting in rust death, resulting in pin and crank into one. Each crank pin replacement requires a lot of workload and time, resulting in the construction time is too long, easy to cause the problem of lying, proposed the development of pumping unit crankpin replacement device, you can shorten the replacement of the crank pin time, Improve work efficiency; reduce stoppage construction time, avoid sand or heavy oil wells and lay wells; device structure is simple, safe and convenient operation.
