Increase the stroke of pumping unit.The patent of invention of 2001 Publication No. CN1061739C discloses electric machine commutating long stroke beam unit motor
Commutation replaces mechanical commutation.It is long that the patent of invention of Publication No. CN102704897B in 2014 discloses a kind of gravitational equilibrium hydraulic pressure
Stroke beam-pumping unit.The patent of invention of 1996 Publication No. CN1031354C discloses a kind of chain-type long stroke pumping unit, be after
Chain-type long stroke pumping unit of new generation after existing chain drive pumping unit.The invention of Publication No. CN1127622C in 2003 is special
Profit discloses a kind of low-height pumping unit with cylindrical chain and long stroke, it has the function of polished rod by one, and has the function of conventional chain
Special cylinder chain, one is provided in space on regular polygon prismatic surface in the linear cylindrical type groove of approximate helical, interior table
Face is the special sprocket wheel of internal thread, one end with longer treasure maesa herb keyhole, the big plate-like wheel of a regular polygon, a deceleration system
It is formed with a balance system.The patent of invention of Publication No. CN101082272B in 2010 discloses giant-scale tower type long stroke pumping
Oil machine enables pumping unit to develop to hugeization to adapt to the requirement that ultradeep well high-quality steam assisted gravity drainage recovers the oil.
The patent of invention of 2014 Publication No. CN102352740B discloses a kind of compound balanced long-stroke oil pumping machine, passes through combined type
Balanced structure mitigates the weight of balance weight.The patent of invention of Publication No. CN1015812 in 1992 discloses a kind of double rollings of biobelt
Tube length stroke beam-pumping unit, is driven using dual-belt dual-cylinder, the rope group formula polished rod eye with pulley, adjustable overhead traveling crane, cross balancing formula
Safety device, planetary cam formula stroke regulating mechanism, the new constructions such as balance frame boom hoisting.The above-mentioned prior art is with their own characteristics,
But in commutation process, shock loading is still larger, and reliability is not good enough；Structure is not compact enough, and balance weight motion range is larger,
Safety is not good enough.Such as the electrical commutation reliability in CN1061739C is not good enough.Lever balance head sheave formula in CN100564794
Long stroke pumping unit mechanical commutation shock loading is big, and structure is more complex.
Invention content
It is an object of the invention to propose that a kind of reversing impact load is small, simple in structure, compact, long lifespan, energy saving
Double pendulum beam rope sheave long stroke pumping unit.
The present invention includes engine base, motor, crank, connecting rod, upper balance arm, lower balance arm, head sheave, upper block, lower tumbler, auxiliary
Bar, steel wire rope, balance weight and sucker rod, wherein motor are fixed on the side of engine base, and the other side of engine base is equipped with plateau, head sheave with
One end of the top rotation connection of engine base plateau, motor drive shaft and crank is coaxially keyed, the other end and connecting rod of crank
One end rotation connection, one end of the other end of connecting rod and upper balance arm, which rotates, to be coupled, upper balance arm successively with upper block center and auxiliary
One end of bar is helped to rotate connection, the other end of upper balance arm couples with the rotation of the top of engine base plateau, one end of lower balance arm and auxiliary
