Description

Tubular column oiling station Technical Field The utility model relates to a pipe column oiling device, which is a device for coating screw thread oil on the end of a pipe column for oil field drilling, and belongs to the technical field of petroleum well repairing equipment. Background When petroleum is used for workover, the thread at the end of the tubular column needs to be coated with screw thread oil before the tubular column is run into the well. In the prior art, the manual brushing mode is generally adopted to brush the screw thread oil on the screw thread at the end part of the tubular column, the manual oiling mode has low efficiency, the screw thread oil is unevenly brushed, and the manual oiling mode is not beneficial to the automatic operation of petroleum well repair. Disclosure of utility model Aiming at the defects in the prior art, the utility model provides the pipe column oiling device which can realize automatic spraying of screw thread oil on the threads at the end part of the pipe column. The pipe column oiling device is characterized by comprising an oiling mechanism base, a guide frame, an air cylinder, a rotating shaft, an oiling component frame body, an air motor and an oil nozzle, wherein the guide frame, the air cylinder, the rotating shaft, the oiling component frame body, the air motor and the oil nozzle are arranged on the oiling mechanism base, the air cylinder is fixed at the rear end of the guide frame, the rotating shaft is rotatably arranged in the oiling component frame body, the rear end of the rotating shaft is connected with a rotary joint, an oil duct communicated with the rotary joint is arranged in the rotating shaft, the front end of the rotating shaft is connected with an oil injection shield and a pressure plate, the oil nozzle is arranged on the oil injection shield, an outlet of the oil duct in the rotating shaft is communicated with the oil nozzle, the oiling component frame body is connected with the guide frame in a sliding mode through the guide column, an air cylinder rod of the air cylinder is connected with the rear end of the oiling component frame body, and the output end of the air motor is connected with the rotating shaft through a chain. When the screw thread oil spraying device works, the end part of the pipe column to be coated with the screw thread oil is positioned at the inner side of the oil spraying protective cover, the rotary joint is connected with the pneumatic oiling machine through a pipeline, and the screw thread oil is supplied to the oil spraying nozzle through the pneumatic oiling machine through the rotary joint and an oil duct in the rotating shaft. When the air motor rotates, the rotating shaft is driven to rotate through chain wheel and chain transmission, so that the oil injection protecting cover at the front end of the rotating shaft is driven to rotate, the oil injection protecting cover drives the oil injection nozzle to rotate, and oil injection is carried out on threads at the end part of the pipe column in the rotating process of the oil injection nozzle. When the cylinder rod of the cylinder stretches out and draws back, the oiling component frame body can be driven to stretch out or retract back, so that oiling components such as the rotating shaft, the pneumatic motor, the oil injection shield, the oil injection nozzle and the like are driven to stretch out or retract back. Further, in order to be convenient for adjust the height of leading truck and be convenient for adapt to the tubular column of different specifications, the leading truck is movable connection about on oiling mechanism base. Further, in order to be convenient for adjust the guide frame height, be provided with high guiding mechanism between guide frame and the oiling mechanism base.
