Design feature of the present utility model and operating principle:
The tail boom balancer of the utility model beam-pumping unit flexible drawing, mainly contain oblique arm support 3, wire rope 4, swing arm 5, jigger 6 is formed, oblique arm support 3 is installed in the tail boom end of walking beam 2, and the lower end of swing arm 5 is packed on the crossbeam 8, and the upper end of swing arm 5 drives wire rope 4 traction jiggers 6 by swing pull rod shaft 504 and wire rope fixator 505 and reciprocatingly slides on its slide rail.When the tail boom balancer of beam-pumping unit flexible drawing was used for the work of common beam oil pumper, its energy-saving principle had two:
One: be the oblique arm support role that is covered with slide rail above reclinate; Load-bearing is sentenced static weight and is calculated, and crank is to the rotation of horse head side, and when the bottom dead centre upstroke began, because reclinate angle [alpha] is greater than the walking beam pivot angle of 1/2nd maximum stroke, the arm of force of this moment was the longest, the moment maximum; Rotate to 180 degree during the left and right sides at crank, whole upstroke process be the arm of force by the longest gradually to the shortest, gradually to minimum process, i.e. during upstroke end, the arm of force at this moment is the shortest, the moment minimum by maximum for moment; Begin to finish in the top dead-centre down stroke to down stroke, promptly return bottom dead centre by top dead-centre, about crank is spent by 180 degree left rotation and right rotation to 360 (about 0 degree when promptly getting back to beginning), whole down stroke process be the arm of force by the shortest gradually to the longest, moment gradually to maximum process, is promptly got back to the position of beginning upstroke bottom dead centre by minimum.
Its two: be by the jigger role that is loaded with balance that slides on the slide rail of on reclinate oblique arm support, laying, load-bearing is sentenced dynamic weight and is calculated, begin by the bottom dead centre upstroke, center and crank output shaft center with crossbeam axle bed 9 are embodiment on an approximate vertical line, and crank is to rotate to horse head side.Rotate to 90 degree during the left and right sides at crank, i.e. upstroke one half, the angle maximum of the central vertical line of connecting rod and swing arm and crossbeam axle; Therefore, jigger sliding stroke of living in from support shaft farthest, formed gravity torque maximum.When crank continues to do upstroke rotation, finish to upstroke, by about 90 degree during to the 180 degree left and right sides, when the angle of the central vertical line of connecting rod and swing arm and crossbeam axle was decreased to the 0 degree left and right sides gradually, the angle of this moment was a minimum zone; At this moment, jigger sliding stroke of living in be by from support shaft farthest to the motion of nearest direction, this moment, formed gravity torque reduced gradually.When crank continues rotation, when beginning to do by top dead-centre to the down stroke of bottom dead centre, by during the left and right sides, promptly arrive down stroke one half to 270 degree about 180 degree, the minimum angular region about the angle of the central vertical line of connecting rod and swing arm and crossbeam axle is spent by 0 is gradually to the maximum angular scope; At this moment, jigger sliding stroke of living in is nearest from support shaft, formed gravity torque minimum.When crank continues to do down stroke rotation, finish to down stroke, by about 270 degree during to 360 degree (about 0 degree when promptly getting back to beginning) left and right sides, when the angle of the central vertical line of connecting rod and swing arm and crossbeam axle is contracted to the 0 degree left and right sides again gradually; At this moment, by direction motion the most farthest, this moment, formed gravity torque increased jigger sliding stroke of living in gradually from support shaft.When crank continues rotation and carries out next cycle, during to the 90 degree left and right sides of next cycle, i.e. upstroke one half of next cycle, it is maximum that the angle of the central vertical line of connecting rod and swing arm and crossbeam axle reaches again; Jigger sliding stroke of living in reaches again farthest from support, and it is maximum that formed gravity torque reaches again.Be greater than the walking beam pivot angle of 1/2nd maximum stroke again because of the angle [alpha] of the oblique arm support that is covered with slide rail above reclinate, the center of gravity of jigger is in the downward direction of slide rail all the time.So circulation and so forth.
More than two energy-conserving actions be applied to simultaneously on the oil pumper, thereby effect is better.
