Support is fixedly connected with base, support is hinged by the main walking beam of walking beam bearing and walking beam, one end of main walking beam is provided with horse head, the other end of main walking beam is connected with rear walking beam by walking beam connecting pin bores, rear walking beam passes through the rod hinge connection of out-phase type connecting pin bores and drive unit, and drive unit is arranged on the side of support away from horse head.
Support is fixedly connected with base, support is hinged by the main walking beam of walking beam bearing and walking beam, one end of main walking beam is provided with horse head, the other end of main walking beam is connected with curved walking beam by walking beam connecting pin bores, curved walking beam passes through the rod hinge connection of curved walking beam pin-and-hole and drive unit, and drive unit is arranged on the side of support away from horse head.
Connecting rod is provided with multiple link connector pin hole, with the length of regulating connecting rod.
In described horse head, between the donkey head lateral plate of both sides, be installed with horse head central layer.
Support is fixedly connected with base, support by walking beam bearing with to be connected walking beam hinged, connect walking beam to be connected with one end of main walking beam by walking beam connecting pin bores, the other end of main walking beam is provided with horse head, main walking beam is also by the close prefix type connecting pin bores of horse head position and the rod hinge connection of drive unit, and drive unit is arranged on the side of support away from horse head.
In described horse head, between the donkey head lateral plate of both sides, be installed with preposition horse head central layer.
In described drive unit, motor is connected with driven wheel by speed reduction unit, and the axle of driven wheel is fixedly connected with crank, crank and rod hinge connection.
Counterweight pin-and-hole is also provided with, to install different counterweights at the free end of crank.
Principle of work of the present invention is: motor converts electrical energy into rotary motion, after reducer casing twice deceleration, utilizes four-bar mechanism to be outstanding straight reciprocating motion of restricting by converting rotary motion.Oil pumper in reality drives deep-well pump oil pumping by horse head, outstanding rope, polished rod, sucker rod.Wherein core component is the four-bar mechanism in the present invention, is made up of the line of crank, connecting rod, walking beam, support and base.Because the bar of support and base is fixed bar, when crank rotates, tail bearing is inevitable is the center of circle with centre bearer, does circular motion.Corresponding walking beam front end is also the center of circle with centre bearer, is that radius does circular motion with forearm length.And horse head cambered surface is also exactly be the center of circle with centre bearer, take forearm length as the circular arc of radius, outstanding rope is again be flexible coupling with hair plait and horse head, and therefore its point of contact characteristics of motion is vertical line to-and-fro movement.The main task of four-bar mechanism is carrying, motion conversion and realize balance, and meanwhile, rationality of its design has significant impact to the serviceability of oil pumper and complete machine overall size and weight.
Four-bar mechanism, in crank rotates a circle, has two positions that crank and connecting rod are located along the same line, is called extreme position.Angle between these two straight lines is called crank angle between two limit positions λ.Three kinds of mechanisms are produced according to the difference of crank angle between two limit positions:
λ=0 symmetrical mechanism, and connecting rod and walking beam pin joint and reduction gearbox output shaft center are on same perpendicular line, as the such as rear-mounted beam-pumping unit of routine;
λ > 0 or λ < 0 belongs to offsetting mechanism.Phased crank walking-beam pumping unit belongs to λ > 0 offsetting mechanism, namely reduction gearbox output shaft center back moves, general λ gets about 12 °, when horse head is on right side, when motor turns clockwise, up stroke is slow, dynamic load reduces, maximum polished rod load declines, and oil pumper load-bearing capacity can make full use of, and then improves sucker rod force-bearing situation.Down stroke is fast, and dynamic load increases, and likely causes the descending difficulty of sucker rod.If when reducer casing allows to be rotated counterclockwise, then the fast down stroke of up stroke is slow.And back-crank pumping unit belongs to λ < 0 offsetting mechanism.
A kind of modular combination oil pumper model provided by the invention, arrange pin-and-hole by horse head, walking beam, connecting rod, crank and base being arranged more, make it the form becoming dismounting or movement, thus the multiple structure and the duty that comprise conventional type, curved beam type, prefix type and Pumping Units can be demonstrated.And most parts wherein can both be reused.The present invention breaches the traditional function of oil pumper model and the unicity of purposes, and combined type interchangeability makes teaching have more high efficiency and vividness, and free style handling can improve manipulative ability and the thinking ability of student further.
