Because oil pumper all is to work in the open air, natural environment is more abominable, need prevent the dust storm precipitation, though the secondary half-section of going up has flexible rain cover, but can't resolve root problem, one: 24 hours reciprocating number of times of linear oil pumping machine are between 8640-25920 times, and rain cover will rupture within 1-2 months, do not have rainproof effect, can cause turn-to-turn, phase fault not to move when sleet enters motor internal; Its two: install on the walking beam on the vehicle-mounted walking beam of autobalance and slide, its objective is and separate underload, make it energy-conservation, in fact the autobalance car is opposite with this purpose, the descending weight of having only sucker rod of current horse head, at this moment the vehicle-mounted walking beam of autobalance top slides to the walking beam front end under and then, and sucker rod heavily added fluid column and heavily adds the balance car weight when current horse head was up, and it is consumed energy more; Its three: secondary have 1/3rd to be installed in undergroundly, and this brings very big tired energy to installation and maintenance; Its four: linear electric motors are elementary because of being contained in the balance weight framework, and the motor long-term motion when the balance weight slight inclination, produces very big monolateral pressure to linear electric motors, increases mechanical wear, and it is consumed energy more.
Summary of the invention
The purpose of this utility model is to overcome the purpose of above-mentioned existence, provides a kind of reasonable in design, and novel structure is practical, can improve oil recovery efficiency, reaches the linear motor oil pumping machine of the pylon walking beam combination of energy-saving and cost-reducing purpose.
The purpose of this utility model is finished by following technical solution, it comprises by A-frame, pylon, walking beam, horse head, control cabinet, described A-frame top is provided with centre bearing, walking beam is housed on it, big horse head is housed before the walking beam, little horse head is housed behind the walking beam, the big horse head of front is connected with sucker rod by wire rope, polished rod eye, the little horse head of back is equipped by wire rope and screw rod, and screw rod is connected with the elementary upper end cover of linear electric motors, and universal joint counterweight dolly is equipped with at the elementary two ends of linear electric motors.
Described universal joint counterweight dolly is installed in upper end cover and gets two ends, the secondary center that is fixed on pylon up and down of linear electric motors, and tower top has secondary lock nut, and pylon is connected with the oil pumper support, and control cabinet is installed in the rear positions of oil pumper support.
The utility model compared with prior art has following technique effect:
1, reasonable in design, novel structure, practical;
2, the pylon overall structure can prevent the sleet intrusion, guarantees that linear oil pumping machine normally moves;
3, the walking beam forearm is the horse head of growing up, and postbrachium is short and small horse head, thereby has solved problem highly not enough below the walking beam;
When 4, the assembling of the balancing weight on the universal joint counterweight dolly was uneven, universal joint can be adjusted automatically, makes the operation of linear electric motors not be subjected to monolateral pressure;
5, the linear electric motors magnet steel is a diametrical magnetization, and diametrical magnetization is bigger by about 10% than axial magnetized thrust;
6, in the end cap up and down of linear electric motors dismountable sliding bearing is housed, bearing greatly reduces labour intensity to directly changing at the scene after application life, maintains easily and keeps in repair;
7, pylon combines the combination that linear oil pumping machine is heavy mechanical equipment and electronic product with walking beam, belongs to electromechanical integrated product.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the assembly structure schematic diagram of parts such as pylon of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail: shown in the accompanying drawing 1,2, the utility model mainly includes A-frame 1, pylon 14, walking beam 3, horse head, control cabinet 17 etc.Described A-frame 1 top is provided with centre bearing 2, walking beam 3 is housed on it, big horse head 4 is housed before the walking beam 3, asinego 5 is housed behind the walking beam 3, the big horse head 4 of front is connected with sucker rod 8 by anterior wire rope 6, polished rod eye 7, the asinego of back 5 is equipped with screw rod 10 by rear portion wire rope 9, and screw rod 10 is connected with the elementary upper end cover 11 of linear electric motors, and universal joint counterweight dolly 12 is equipped with at the elementary two ends of linear electric motors.
Described universal joint counterweight dolly 12 is installed in the two ends of upper end cover 11, secondary 13 of linear electric motors are fixed on the center of pylon 14 up and down, tower top has secondary lock nut 15, and pylon 14 is connected with oil pumper support 16, and control cabinet 17 is installed in the rear positions of oil pumper support 16.
The utility model adopts the radially pipe type straight line permanent magnet synchronous motor of magnetic circuit, drive the back asinego header structure in two horse heads, the elementary universal joint counterweight dolly of being with of linear electric motors, secondary reciprocating along linear electric motors, the arc tangent line of the big or small horse head by front and back seesaws linear oil pumping machine and remains vertical force; Either party load strengthens when the front and back of oil pumper, and main power machines linear electric motors temperature raises, and it is too high that control cabinet can be monitored out electric machine temperature rise automatically, and cooling blower is opened automatically to motor cooling cooling, guarantees that oil pumper normally moves.Linear electric motors elementary can produce unilateral magnetic force during along secondary axially-movable, and the mechanical loss of unilateral magnetic force expanded motor makes the motor secundly; For guaranteeing the even of motor gas-gap, reduce the mechanical loss of motor, non magnetic abrasion-resistant slide bearing is installed in the end cap up and down of motor, guarantee linear electric motors long-term non-stop run in 24 hours, satisfy the requirement of oil field to oil production equipment.
