Summary of the invention:
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of rearmounted triangle long stroke pumping unit that goes the big figure, and makes it to realize long stroke, and is energy-efficient again, have simple in structure, the characteristics that operational reliability is high.
The utility model is to realize above-mentioned purpose by following technical solution.
In a kind of rearmounted triangle of the utility model goes the big figure the structure of long stroke pumping unit, be provided with connecting rod, triangle rocker, push rod, wire rope, pulley, walking beam, horse head etc., one end of connecting rod is connected with an end of crank, and the other end of connecting rod then is connected with an end of walking beam; The middle part of walking beam is installed in the top of pylon, and an end of walking beam is connected with connecting rod, and the other end of walking beam then is equipped with horse head; The triangle rocker is installed in by lower fulcrum on the postbrachium of walking beam, and the central bearing point of triangle rocker is connected with an end of push rod, and the last fulcrum of triangle rocker is connected with an end of wire rope; One end of push rod is installed on the pylon, and the other end of push rod is connected with the central bearing point of triangle rocker; Upper end at horse head is equipped with pulley, and part is equipped with roller in the forward position of horse head; One end of wire rope is installed on the last fulcrum of triangle rocker, and the other end is walked around pulley and is connected with rope locking device with horse head; An end that is connected with connecting rod at walking beam is equipped with the beam balance counterweight; Lower fulcrum one end at the triangle rocker is equipped with the counterweight of triangle rocker.
The utility model has following beneficial effect compared with prior art:
1, overcome the drawback of existing traditional four-bar mechanism oil pumper, realized long stroke, improved pump efficiency, good energy-conserving effect.
2, simple in structure, easy to maintenance, the operational reliability height.
3, flexible design can adapt to different operating modes, can satisfy the specific (special) requirements of different oil wells.
