The four cylinder hydraulic cylinders have upper and lower two pairs of pin shaft holes, upper pin hole to be connected with walking beam by axis pin so that hydraulic pressure Cylinder can rotate with respect to walking beam;Lower bearing pin hole is connected by axis pin with pedestal simultaneously so that hydraulic cylinder can be with respect to pedestal It rotates.
The oil inlet of fuel tank 7 is connected with one end of an oil inlet pipe for being parallel to walking beam 8, this section of oil inlet pipe is fixed on walking beam On 11;The other end of the oil pipe 8 is connected with the straight mouth of high pressure slow-speed of revolution rotation seal joint 10A, is used for this section of oil pipe and hypomere Sealing when oil pipe relatively rotates during the work time;The bending mouth of rotation seal joint 10A and one are perpendicular to walking beam One end of 11 oil pipe is connected, this section of oil pipe is fixed on holder 1;The other end of oil pipe be parallel to pedestal 2 and with check valve 14A Oil outlet be connected;The oil inlet of check valve 14A is connected with a rotation seal joint 15A bending mouths, rotation seal joint 15A's Zhi Kou is connected with the oil outlet 13A of four cylinder hydraulic cylinders 13.
The fuel tank is connected with the walking beam end of pumping unit, and when horse head declines, hydraulic oil liquid level rises in fuel tank, together When whole fuel tank height be improved;When 11 clockwise oscillation of walking beam, hydraulic oil is flowed out from hydraulic cylinder oil outlet 13A, unidirectionally Valve 14A is opened, and hydraulic oil is back in fuel tank 7, while fuel tank 7 highly improves.
The oil outlet of fuel tank 7 is connected with one end of a flowline for being parallel to walking beam 9, the flowline 9 stated with into Oil pipe 8 is symmetrical about 11 both sides of walking beam, and is fixed on walking beam 11;The other end of this section of oil pipe and high pressure slow-speed of revolution rotatory sealing The straight mouth of connector 10B is connected, sealing when relatively rotating during the work time for this section of oil pipe and hypomere oil pipe;Rotation The bending mouth of seal nipple 10B is connected with one end of an oil pipe perpendicular to walking beam, and the oil pipe is about 1 both sides pair of holder Claim, and is fixed on holder 1;The other end of the oil pipe is parallel to pedestal 2 and is connected with the oil inlet of check valve 14B;Check valve The oil outlet of 14B is connected with the bending mouth of rotation seal joint 15B, the Zhi Kou of rotation seal joint 15B and four cylinder hydraulic cylinders 13 Oil inlet 13B be connected.
When 11 counter-clockwise swing of walking beam, hydraulic oil is flowed out from fuel tank 7, flows through oil outlet pipe, and check valve 14B is opened, warp It crosses hydraulic cylinder fuel feed hole 13B and flows into hydraulic cylinder chamber, react on piston, further push walking beam counter-clockwise swing.
As shown in figure 3, four cylinder hydraulic cylinders 13 include oil outlet 13A, hydraulic cylinder fuel feed hole 13B, four cylinder piston rod 13C, it is living Fill in 13D, four cylinder cylinder barrel 13E, hydraulic cylinder lower bearing pin hole 13M, hydraulic cylinder upper pin hole 13N.
Four cylinder hydraulic cylinders, 13 upper pin hole 13N is connected with walking beam 11, and lower bearing pin hole 13M is connected with pedestal 2;Hydraulic cylinder piston 13D is fitted into after being connected with piston 13C in four cylinder cylinder barrel 13E;Hydraulic cylinder oil outlet 13A is connected with rotation seal joint 15A to be followed by Enter fuel tank oil inlet pipe;Hydraulic cylinder fuel feed hole 13B accesses fuel tank oil outlet pipe after being connected with rotation seal joint 15B.
When 11 clockwise oscillation of walking beam, walking beam 11 pushes piston rod 13D and piston 13C to move downwardly together, pushes liquid Pressure oil is flowed out from oil outlet 13A;When 11 counter-clockwise swing of walking beam, piston rod 13D and piston 13C is pushed to move upwardly together, Hydraulic oil is flowed into from fuel feed hole 13B in hydraulic chamber.
The operation principle of the present invention is that:
Down stroke, since the dead weight of rod string drives the horse head 12 of pumping unit to move downward, i.e., walking beam 11 is put clockwise Dynamic, walking beam 11 pushes piston rod 13C to move downward by axis pin at this time, and the oil storage between hydraulic cylinder cylinder sleeve 13E and piston 13D is empty Between reduce, the Incoercibility of hydraulic oil so that oil pressure increases in cylinder barrel, further such that the check valve in oil inlet pipe system 14A is opened, and hydraulic oil after cylinder barrel oil outlet 13A pressure releases by flowing back into fuel tank 7,7 position of reflux and fuel tank of hydraulic oil Raising, hydraulic energy transfer is stored for potential energy, is prepared for next stroke.Simultaneously because the reduction of area of passage, So that piston rod 13C declines is obstructed, thereby reduces speed of the walking beam 11 to lower swing, motor no longer does negative work at this time, reaches The effect of balance.
Upstroke, under the drive of crank 4, walking beam 11 starts counter-clockwise swing, and walking beam 11 is pulled by axis pin and lived at this time Stopper rod 13C is moved upwards, and the oil storage space between hydraulic cylinder cylinder sleeve 13E and piston 13D increases, and oil pressure reduces in cylinder barrel, uses Check valve 14B in oil pipe line system is opened, and hydraulic oil enters hydraulic cylinder chamber by hydraulic cylinder fuel feed hole 13B and reacts on Piston 13D, and then walking beam 11 is pushed to be swung up.The potential energy of the hydraulic oil stored in upper one-stroke simultaneously balances part oil pumping The weight of roofbolt reduces motor work done during this, has achieved the effect that balanced energy conservation.
It is enlightenment with above-mentioned desirable embodiment according to the present invention, through the above description, related field work people Member can carry out various changes and amendments without departing from the scope of the technological thought of the present invention' completely.This invention Technical scope is not limited to the contents of the specification, it is necessary to determine its technical scope according to right.
