Slant-pull double side position-moving type vertical pumping unit

A slant-pull double side position-moving type vertical pumping unit, which is characterized in that as follows: a pumping unit bracket is arranged on a pumping unit base; a pumping unit upright bracket is arranged firmly on the top of the pumping unit bracket; a front and a rear driven pulley brackets are arranged on the top of the pumping unit upright bracket; an oil pumping driven pulley and a balance driven pulley are arranged at the two sides of the pumping unit base; a driving wheel is arranged firmly on the pumping unit base; the one end of a flexible part is arranged firmly on a smooth rod of an oil pumping wellhead by means of a smooth rod hanging rope device; the flexible part is wrapped in turn on an oil pumping driven pulley, the driving wheel and the balance driven pulley, and the other end is fixed on a balance weight tray. The utility model has the advantages in that the barycenter of the whole vertical pumping unit can be moved downwards so as to make the device has an easy manufacture, convenient transportation, a smooth running, a convenient maintenance and maintain; meantime, the abdication operation of workover operation can be realized without removing the whole machine, and thus to offer a safe and convenient operation means for workover operation and other corresponding operations, therefore has an expansive application prospect.
