An oil pipe scraping device
ActiveCN224282596Usmooth motionavoid forceDrilling rodsCleaning apparatusAxial displacementOil drilling
This utility model belongs to the technical field of oil drilling and production equipment, specifically relating to a tubing scraping device. The device includes an upper connector and a scraping head, as well as a rotating mechanism connecting the upper connector and the scraping head. The rotating mechanism includes a support sleeve connected to the upper connector and a rotating body with one end anti-detached from the support sleeve and the other end connected to the scraping head. Track grooves are evenly distributed on the outer wall of the rotating body. A guide pin is provided at the end of the support sleeve away from the upper connector. The track grooves and guide pin are slidably engaged to allow the rotating body to rotate and axially displace relative to the support sleeve when the tubing scraping device is lifted or lowered. In use, by lifting or lowering the device, the track grooves of the rotating body slidably engage with the guide pin of the support sleeve. The guide pin slides along the track grooves, forcing the rotating body to rotate and generate axial displacement, thereby driving the scraping head to actively rotate and move axially. Compared with the prior art, which passively drives the scraping head through scraper friction, this effectively improves scraping quality and efficiency.
