Description
Technical field
The utility model relates to a kind of oil pumper, relates to specifically a kind of suspension point Mobile oil well pump, belongs to petroleum machinery technical field.
Background technology
In recent years, in domestic oil pumper equipment, there is the multiple tower shelf type oil pumping machine different from conventional beam-pumping unit, especially a kind of without beam type energy-saving oil pumping machine, it is this that what all adopt without beam type energy-saving oil pumping machine is tower-type vertical structure, rotarily drive wire rope by the motor in pylon, wire rope is connected with ballast box and oil-extractor polish-rod respectively with transition wheel through transition wheel, suspension wheel again, in the time that motor comes and goes rotation, realize the reciprocating motion of wire rope, thereby drive the upper and lower motion of oil-extractor polish-rod, and carry out down-hole oil production.
Because transition wheel and support etc. stretch out the limitation of cantilever support, although the support that transition wheel stretches out moves setting after having the performance of backing or complete machine, all in actual workover treatment, cause following defect: 1, after complete machine, move and cause the large waste plant equipment of workload and workman man-hour because of unsafe factor; 2, after complete machine, move or support backs and all belongs to dangerous job specification, potential safety hazard is too many, and danger is too large; 3, during due to well workover, after complete machine, move or reason that support backs, when well workover rear haulage band and sucker rod and well head central involution, very difficult.Also can not return to originally position location accurately.
In order to overcome the various defects of above-mentioned oil pumper, occur that one is convenient to complete machine and moves, while making well workover, all there are enough activity spaces, really possess the tilting program controlled energy-saving oil pumping machine of the requirement of shaft mouth operation safety.The overall structure of this tilting oil pumper is that the middle complete machine of working at the scene turns forward, and is provided with two front support columns before body, and suspension wheel support is fixed on before body upper end.But this kind of structure has following defect:
