Key is connected, and synchronous pulley B is connected to synchronous pulley A by timing belt；The nut of synchronous pulley A and ball screw assembly, is connected, rolling
The secondary nut of ballscrew is connected by bearing B and fixed support, and fixed support, which is bolted, to be fixed on ground；Leading screw two
Hold smooth part by bearing A connection leading screw supports, roller is contained in leading screw support bottom, can be slided along guide rail level；Leading screw two
There is screw thread at end, and axle sleeve is connected through a screw thread with leading screw end, and axle sleeve includes thrust bearing；Steel cable termina passes through axle sleeve and thrust
Bearing is connected with steel wire rope；Steel wire rope bypasses rail assembly C and is connected with polished rod eye B, reconnects flexible linking device；Flexible connection
Mechanism is two belts, and polished rod eye B is connected with a belt, and this belt bypasses rail assembly B, day wheel assembly, rail assembly A and connected
Meet polished rod eye A；Another belt connects polished rod eye A, bypasses rail assembly A, day wheel assembly and is connected with ballast box；Ballast box is with helping
Positive wheel group is connected, and righting wheel group can be slided up and down along righting guide rail.Rail assembly, day wheel assembly and righting guide rail are installed in
On truss assembly, truss assembly is fixed by base.
The beneficial effects of the invention are as follows：The structure of one machine twin-well makes the load of two mouthfuls of wells mutually balance, and reduces motor
Power consumption, improves the efficiency of oil pumping system；By adjusting rope capacity, the twin-well that different distance can be achieved recovers the oil；By changing
Become the length of leading screw to change the stroke of oil pumper, realize stroke jig frequency stepless adjustable；Whole system have it is simple in construction, surely
Qualitative good, reliability is high, energy-efficient, the characteristics of wide adaptability, is easily installed and safeguards.
