Inclined program control energy-saving oil pumping machine

2012 
The utility model discloses an inclined program control energy-saving oil pumping machine, which comprises a machine frame, wherein an oil pumping machine polish rod and a counter weight box are connected to the machine frame; a well mouth is formed on one side of the machine frame; the oil pumping machine polish rod is positioned in the well mouth and can move up and down along the well mouth; a foundation is below the machine frame; a lower base is fixedly arranged on the foundation; the lower end of the machine frame is hinged with the lower base by a central support shaft; and the machine frame can incline forward and backward by 5 to 10 degrees by taking the central support shaft as an axis. By the inclined program control energy-saving oil pumping machine, the defect that a suspension wheel support or an integral machine base moves outwards during the major workover and minor workover of various walking beam-free oil pumping machines is overcome really, so that worker activity space is sufficient at the periphery of the well mouth during well workover, and the real safety of major workover operation is ensured.
