Brief description of the drawings
Fig. 1 is the structural representation of a kind of beam pumping unit of the utility model.
Detailed description of the invention
Consult a kind of beam pumping unit shown in Fig. 1, comprise base 1, frame 2, support 3, crank 4, drive unit 5 and walking beam 6, described frame 2 and support 3 are installed on base 1, described drive unit 5 is arranged in frame 2, the output of described drive unit 5 is connected with the first gearbox 7, the output of described the first gearbox 7 is connected with driving gear 8, described frame 2 is provided with the second gearbox 9, the input of described the second gearbox 9 is provided with the driven gear 10 matching with described driving gear 8, described crank 4 is arranged on the output shaft of the second gearbox 9, on described crank 4, be hinged with a connecting rod 11, the other end of described connecting rod 11 is hinged on walking beam 6 one end, described walking beam 6 other ends are provided with horse head 12, described walking beam 6 is hinged on support 3, described walking beam 6 is provided with damper 13 with support 3 junctions.
Described the first gearbox 7 is arranged in frame 2, is also provided with the controller 14 for accessory drive 5 in described frame 2, and described controller 14 is provided with emergency stop switch 15, and described base 1 is provided with redundant electrical power 16, and described redundant electrical power 16 is connected with controller 14.
