Description of drawings
Accompanying drawing is the structural representation of a kind of embodiment of the utility model.
Among the figure: 1, support 2, polished rod eye 3, main rope 4, wire rope pulley 5, rope sheave support, 6, directive wheel support 7, directive wheel 8, balance rope 9, upper rail 10, chain wheeling support 11, sprocket wheel A12, chain drive-belt 13, link 14, chain connect bearing pin 15, reductor 16, driving chain 17, sprocket wheel B18, gear-box 19, sprocket wheel C20, sucker rod 21, balance weight 22, top rail 23, crossbeam and adjust leading screw 24, lower transverse beam 25, crossbeam 26, lower guideway
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
A kind of example block diagram of the present utility model is provided, and as shown in drawings, chain type twin-well oil-pumping machine of the present utility model comprises frame, chain drive mechanism, oil pumping operating mechanism and balanced controls.
Frame comprises two supports placed side by side 1, crossbeam 25 is installed on each support 1, bilateral symmetry, as middle cross beam, the also fixedly top rail 22 and the lower transverse beam 24 up and down of crossbeam 25, connect crossbeam between two crossbeams 25 and adjust leading screw 23, adjust leading screw 23 by crossbeam and can adjust two distances between the crossbeam 25, to adapt to the needs of different well spacings.
Chain drive mechanism is fixed on the top rail 22, comprise by the motor-driven reductor that is in transmission connection successively 15, driving chain 16, sprocket wheel C19, gear-box 18 and sprocket wheel B17, reductor 15, driving chain 16, sprocket wheel C19 drive the power shaft of two identical gear-boxes 18, two sprocket wheel B17 that are installed in the output shaft axle head of gear-box 18 are rotatablely moved synchronously, horizontal circle is provided with chain drive-belt 12 between sprocket wheel B17 and the sprocket wheel A11, and chain drive-belt 12 is done synchronous gyration.Connect bearing pin 14 by chain on the chain drive-belt 12 link 13 is set, the two ends up and down of link 13 are stuck between upper rail 9 and the lower guideway 26, under the drive of chain drive-belt 12, connect bearing pin 14 promotion links 13 by chain and between last lower guideway, make horizontal reciprocating movement.
