Lifting platform type pumping unit

Abstract

The invention relates to the technical field of pumping units, in particular to a lifting platform type pumping unit, which comprises a mounting support, a supporting base, a slider, a scissor type lifting platform, a counterweight sleeve, a counterweight cylinder, a left fixed pulley, a right fixed pulley and a sucker rod; the supporting base is arranged under the mounting support, and a power system is fixedly mounted on the supporting base; a pair of slider rails are fixedly mounted on the inner lower part of the mounting support, and the slider is mounted between the slider rails; the slider can be driven by the power system to move up and down; a crossbeam is fixedly mounted at the middle of the mounting support, and the scissor type lifting platform which can be extended and retracted is mounted on the crossbeam and located in the mounting support. The lifting platform type pumping unit has a reasonable and compact structure, and is convenient to use; the oil-pumping stroke can be increased by the scissor type lifting platform, consequently, the efficiency of oil production can be increased, and the oil output can be increased; the scissor type lifting platform is a link structure, the weight is light, and drive is flexible; the power of a used electromotor is low, consequently, more energy can be saved, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of pumping units, and relates to a lifting platform type pumping unit. Background technique [0002] At present, the mechanical oil production method adopted in China is mainly the deep well pump rod production with the beam-type deep well pump device; but with the continuous increase of well depth and production and the frequent occurrence of complex conditions for mining, the disadvantages of the beam pumping unit are also increasing. It is increasingly exposed; especially when increasing the stroke, it is necessary to increase the swing angle of the beam, which makes the beam pumping unit bulky and heavy; at the same time, the configuration power of the motor driving the beam pumping unit increases, and the power consumption big. Contents of the invention [0003] The present invention provides a lifting platform pumping unit, which overcomes the deficiencies of the prior art and can effectively s...
