采用平面连杆系统的综合方法将常规游梁式抽油机与辅助连杆综合，构成多种增程式游梁式抽油机的设计方案及相应的平面连杆系统，用以增加常规游梁式抽油机的冲程。针对各个设计方案，进行受力分析和冲程计算，推导出抽油杆增程系数和连杆驱动力增力系数计算式。分析结果表明，采用该方法在保留常规游梁式抽油机的优点和保持其结构及尺寸基本不变的前提下，可有效地增加游梁式抽油机的冲程 Adopting the integrated method of plane connecting rod system, the conventional beam pumping unit and auxiliary connecting rod are combined to form a variety of design schemes of extended-range beam pumping unit and the corresponding plane connecting rod system to increase the conventional beam Pumping stroke. For each design scheme, the stress analysis and stroke calculation are carried out, and the calculating formulas of the extended range coefficient of the sucker rod and the force coefficient of the connecting rod driving force are deduced. The analysis results show that this method can effectively increase the stroke of the beam pumping unit under the premise of retaining the advantages of the conventional beam pumping unit and keeping its structure and size basically unchanged
