Design feature of the present utility model and operating principle:
The utility model is the compound tail boom slide balance of an a kind of curved beam oil pumper, mainly is bent downwardly the α angle by crooked postbrachium 201, tail boom 202 (prolongation of postbrachium 201) and rolling wheel support seat 3, and roller 4, swing arm 5, slide balance bar assembly 6 is formed; Rolling wheel support seat 3 is installed in the end of walking beam 2 tail booms 202, the lower end of swing arm 5 is packed on the crossbeam 8, the upper end disjunctor head 502 and the slide balance bar assembly 6 of swing arm 5 is hinged or is affixed, the coincide crimping mutually and doing on its spigot surface of the slide rail 604 of slide balance bar assembly 6 and the rolling spigot surface of roller 4 reciprocatingly slides, and forms the little four-bar linkage structure between swing arm, slide balance bar assembly, roller, the curved beam postbrachium.
During the work of the compound tail boom slide balance of curved beam oil pumper, its energy-saving principle has two.
One: the energy-conserving action of curved beam postbrachium, the load-bearing of roller 4 are sentenced static weight and are calculated, and crank is to the rotation of horse head side, and when the bottom dead centre upstroke began, the arm of force length of this moment was in longer scope, and moment is in a big way; When crank rotates to the 180 degree left and right sides, whole upstroke process is the arm of force, and (arm of force also can be by the longest gradually to the shortest to the shortest gradually again to the longest gradually by long, this is determined by the angle of bend of curved beam postbrachium), moment by more gradually to maximum again gradually to the process of minimum (moment also can by maximum gradually to minimum); When being the upstroke end, the arm of force of this moment is the shortest, the moment minimum; 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 is that the arm of force is got back to long (arm of force also can by the shortest gradually to the longest) again gradually to the longest gradually, and moment is got back to greatly the process of (moment also can by minimum gradually to maximum) again gradually to maximum gradually; Promptly get back to the position of beginning upstroke bottom dead centre.
Its two: be by the tail boom slide balance part role on the curved beam postbrachium; Referring to Fig. 1, the load-bearing of roller 4 is sentenced dynamic weight and is calculated, begin by the bottom dead centre upstroke, and be embodiment with the center and the crank output shaft center of crossbeam axle bed 9 being similar on the vertical line, 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, slide balance bar assembly 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 180 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, slide balance bar assembly 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, slide balance bar assembly 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 slide balance bar assembly 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; Slide balance bar assembly sliding stroke of living in reaches again farthest from support, and it is maximum that formed gravity torque reaches again.Circulation and so forth.
More than two energy-conserving actions be applied to simultaneously on the oil pumper, thereby effect is better.
