Three, summary of the invention
The purpose of this utility model be to overcome in the above-mentioned prior art existing shortcoming or not enough and provide that a kind of improved transmission is more reasonable, structure is simpler, more convenient operation, the scope of application are wider, safety and reliability, more material-saving, energy-conservation, feed screw nut counterweight oil pumper is driven on the top efficiently.
Feed screw nut counterweight oil pumper is driven on top described in the utility model, comprise hanger, belt, pulley support, pulley, motor, brake, last thrust bearing, leading screw, nut counterweight seesaw frame, guide wheel, frame, switch board, following thrust bearing and base, described frame and switch board are installed on the base, the leading screw two ends be installed on be fixed on the frame top and the bottom on, on the following thrust bearing, motor is installed on frame top, its output shaft is connected with the leading screw upper end, as the screw pair driving link, described nut counterweight seesaw frame is set upright in rack rail by guide wheel, mesh with leading screw, as screw pair driven member double as counterweight, be connected with hanger by the pulley of belt through being installed on frame top, described brake is installed on by the motor of frame top, and motor and brake are electrically connected with switch board.
Wherein, described leading screw is single head or bull ball-screw or regular screw threads leading screw.Described nut counterweight seesaw frame, its nut and counterweight seesaw frame are integral body or split-type structural.Described motor and switch board are formed switched reluctance machines or brshless DC motor speed governing exchange system.Described guide wheel is for leading boots, guide block or Guiding wheel structure form commonly used.Electromagnetic braking or mechanical braking form of structure are adopted in described brake.Described belt is belt or wire rope.
The utility model compared with prior art has following advantage:
1, the vertical frame top that is installed in of speed governing reversing motor directly drives the leading screw forward and backward, orders about the upper and lower reciprocating motion and by the upper and lower reciprocating motion of belt and polished rod eye traction polished rod in rack rail of nut counterweight seesaw frame, and then drives the deep well pump oil pumping.
2, this utility model adopts motor to become switched reluctance machines or brshless DC motor speed governing exchange system with the Based Intelligent Control group, can realize stroke, the stepless adjustment of jig frequency.
3, polished rod uplink and downlink speed step-less adjustment respectively, especially leading screw as the screw pair driving link, the nut seesaw frame has reduced bracket height as screw pair driven member and double as counterweight, has increased effective stroke.
4, simple and compact for structure, drive disk assembly is few, and route is short, and performance is safe and reliable.
