The invention relates to the technical field of petroleum extraction, in particular to a hydraulic transmission reciprocating type petroleum extraction pumping unit. By arranging a driving motor, an air suction mechanism and a cooling mechanism, effective cooling and heat dissipation can be carried out at the friction position of a steel wire rope and a bracket, cooling and heat dissipation can becarried out on the joint of the steel wire rope, a first fixed pulley and a second fixed pulley, so that the cooling and heat dissipation effect of the steel wire rope in use is effectively improved,the influence of friction heat production on the steel wire rope is reduced, and the using safety of the steel wire rope is ensured; and by arranging a lifting mechanism, the air suction mechanism, asecond transmission mechanism and a first transmission mechanism, the height of a hydraulic cylinder in a box can be adjusted, then the tail end height of the steel wire rope is adjusted, the heightof a pumping device fixedly connected with the tail end of the steel wire rope can be conveniently adjusted, then driving pumping is carried out on the pumping devices with different installation heights, and the using range of the pumping unit is enlarged and the convenience of the pumping unit is improved.
本发明涉及石油开采技术领域,尤其涉及一种液压传动往复式石油开采抽油机,通过设置的驱动电机、吸气机构和降温机构,能对钢丝绳与支架摩擦处进行有效的降温散热,还能对钢丝绳与第一定滑轮和第二定滑轮连接处进行降温散热,从而能有效的提高了钢丝绳在使用时的散热降温效果,有利于降低摩擦产热对钢丝绳的影响,确保钢丝绳在使用的安全性;通过设置的升降机构、吸气机构、第二传动机构和第一传动机构,能实现对位于箱体内液压缸的高度进行调节,继而能对钢丝绳的末端高度进行调节,便于实现对与钢丝绳末端固定连接的抽油装置高度可调节,继而利于实现对安装高度不同的抽油装置进行驱动抽油,提高了抽油机的使用范围和便利性。
