In figure, 1 housing, 2 single-chip microcomputers, 3 pumping-unit motors, 4 control motor, 5 reductors, 6 leading screws, 7 nuts, 8 balancing weights, 9 electromagnetic coils, 10 movable pulleies, 11 slide rails.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 is structural representation of the present utility model, Fig. 2 is scheme of installation of the present utility model, shown in composition graphs 1, Fig. 2, the automatic adjustment of oil pumper, this device comprises housing 1, single-chip microcomputer 2, pumping-unit motor 3, controls motor 4, reductor 5, leading screw 6, nut 7, balancing weight 8, housing 1 is installed on walking beam on pumping units afterbody, controlling motor 4 is fixedly mounted in housing 1, the output controlling motor 4 connects leading screw 6 by reductor 5, leading screw 6 is set with nut 7, nut 7 and balancing weight 8 affixed.The reductor 5 that rotates through controlling motor 4 passes to leading screw 6, and leading screw 6 is rotated together, and because nut 7 is sleeved on leading screw 6, therefore the rotation of leading screw 6 can cause nut 7 advance along hand of spiral or retreat, thus drives balancing weight 8 to be moved.Single-chip microcomputer 2, control motor 4, reductor 5, leading screw 6, nut 7, balancing weight 8 are all positioned at housing 1 inside, and so from without, this device and walking beam have a style of one's own.Pumping-unit motor 3 is connected with the input of single-chip microcomputer 2, the output connection control motor 4 of single-chip microcomputer 2.The equilibrium state moment due to oil pumper can affect the size of current of pumping-unit motor 3, is monitored the size of current of pumping-unit motor 3, can know the equilibrium state of current oil pumper by single-chip microcomputer 2.Pumping-unit motor 3 can pass to single-chip microcomputer 2 the information of curent change, show after single-chip microcomputer 2 computing that balancing weight 8 needs the distance of movement, then instruction is sent to and control motor 4, the rotating of regulable control motor 4 and the revolution of positive and negative dress, make balancing weight 8 move to a suitable position.In the utility model, single-chip microcomputer adopts commercially available prod, the MASK single-chip microcomputer that such as Hong Kong Qi Xin Science and Technology Ltd. produces.
After balancing weight 8 moves to suitable position, now oil pumper has reached desirable equilibrium state, and in order to fix in time balancing weight 8, electromagnetic coil 9 is housed bottom housing 1, electromagnetic coil 9 is connected with the output of single-chip microcomputer 2.Therefore, controlled by the power on/off of single-chip microcomputer 2 pairs of electromagnetic coils 9, when electromagnetic coil 9 is energized, produces galvanomagnetic-effect, balancing weight 8 is fixed on rational position.And when balancing weight 8 needs change position to be moved again, single-chip microcomputer 2 controls electromagnetic coil 9 power-off, galvanomagnetic-effect disappears, and balancing weight 8 can be moved again, regulates the equilibrium state of walking beam on pumping units.
Further, slide rail 11 is housed bottom housing 1, balancing weight 8 can slide on slide rail 11.Slide rail 11 ensure that the directionality of balancing weight 8 movement, preventing its sideslip when moving, causing harmful effect to the equilibrium state of walking beam on pumping units.
During use, pumping-unit motor 3 can pass to single-chip microcomputer 2 at any time the information of curent change, show that balancing weight 8 need the state of movement after carrying out computing by single-chip microcomputer 2 pairs of current informations.Such as, the electric current when walking beam rises reduces, and illustrates that counterweight reduces, needs balancing weight 8 to move forward; Electric current when walking beam rises strengthens, and illustrates that counterweight increases, needs balancing weight 8 to move backward; When walking beam declines, electric current reduces, and illustrates that counterweight reduces, only relies on the deadweight of sucker rod that walking beam can be made to decline, now, need balancing weight 8 to move backward, to keep balance; When walking beam declines, electric current strengthens, and illustrates that counterweight increases, and the deadweight of sucker rod is inadequate, now, needs balancing weight 8 to move forward, to keep balance.This information can be converted to instruction and send to control motor 4 by single-chip microcomputer 2 in time, and the leading screw 6 that rotates through controlling motor 4 drives nut 7, and the balancing weight 8 be connected with nut 7 can obtain movement.After balancing weight 8 moves to desirable position, single-chip microcomputer 2 can send the instruction of stopping, and now, control motor 4 and stop operating, balancing weight 8 is also no longer moved.Single-chip microcomputer 2 starts immediately to be energized to electromagnetic coil 9, makes electromagnetic coil 9 produce galvanomagnetic-effect after stopping power supply to control motor 4, produces magnetic force and attracts, prevent its position from changing, keep the equilibrium state of oil pumper to balancing weight 8.When the equilibrium state of oil pumper needs to adjust again time, single-chip microcomputer 2 is first to electromagnetic coil 9 power-off, it is made to lose magnetic force sucking action to balancing weight 8, then single-chip microcomputer 2 recovers the control action to controlling motor 4, control motor 4 rotates and again adjusts the position of balancing weight 8, regulate the equilibrium state of oil pumper, go round and begin again, so circulate.
Automatic control system is introduced balance of well pumping unit device by the utility model, according to the curent change of pumping-unit motor, automatic decision goes out the current equilibrium state of oil pumper, by controlling motor positive and inverse, drive balancing weight is moved, and change the equilibrium state of walking beam, control accuracy is high, and can automatically regulate at any time, time saving and energy saving; Add electromagnetic coil as self-locking mechanism at housing bottom, after balancing weight moves to correct position, electromagnetic coil energising attracts balancing weight, prevents balancing weight to be moved; The utility model structure is simple, and can control to adjust at any time the equilibrium state of oil pumper, precision is high, uses manpower and material resources sparingly, and ensures production safety.
