The pumping unit comprises a base, wherein the bottom of a frame is placed on the base; the cylinder body of a hydraulic cylinder is fixed to the base; a cylinder rod of the hydraulic cylinder is fixedly connected with the frame; the frame is provided with an axial slide way; a weight box is provided with a plurality of guide wheels; the guide wheels on the weight box are placed into the slide way of the frame; the top of the frame is provided with a switch reluctance motor; a winding drum is fixed to a power output shaft of the switch reluctance motor, and is positioned over the center of the upper surface of the weight box; one end of a weight box fixing steel rope is fixed to the center of the upper surface of the weight box, and the other end of the weight box fixing steel rope is fixed to the winding drum; a head sheave is arranged on the top of the frame through a shaft; a steel rope connected with a pumping rod is wound on the head sheave; the tail end of the steel rope connected with the pumping rod is fixed to the weight box. The pumping unit has the advantages of simple structure, low manufacturing cost and time-saving and labor-saving effects during movement.
Description
Technical field:
The utility model relates to the oil pumper that a kind of oil field operation is used.
Background technology:
The oil pumper ubiquity complex structure that oil field operation is used at present, high cost problem, in addition in the time running into Ka Jing or well-flushing in oil field operation process, oil pumper entirety need to be removed, be that multiple workmans remove oil pumper entirety with Chain block at present, translational speed is slow, and recruitment is many, waste time and energy, move and once approximately need time half a day.
Summary of the invention:
Technical problem to be solved in the utility model is to provide a kind of simple in structure, and cost is low, and entirety is removed time saving and energy saving oil pumper.
Above-mentioned purpose is achieved in that it comprises base, the bottom of frame is placed on base, the cylinder body of hydraulic cylinder is fixed on base, cylinder bar and the frame of hydraulic cylinder are connected and fixed, hydraulic cylinder works, can drive frame to move on base, in frame, be provided with axial slideway, ballast box is provided with several guide wheels, guide wheel on ballast box is placed in the slideway in frame, frame top is fixed with switched reluctance machines, on switched reluctance machines power output shaft, be fixed with reel, reel be positioned at ballast box upper face center directly over, one end of the fixing steel cable of ballast box is fixed on the centre of ballast box upper surface, the other end of the fixing steel cable of ballast box is fixed on reel, head sheave is contained in the top of frame by axle, the steel cable being connected with sucker rod is in head sheave, the tail end of the steel cable being connected with sucker rod is fixed on ballast box.Switched reluctance machines work, drives ballast box to do upper and lower reciprocating motion, thereby drives the steel cable being connected with sucker rod to do upper and lower reciprocating motion.
The utility model has the advantages that: simple in structure, cost is low, oil pumper integrated moving is time saving and energy saving, and translational speed is fast, and recruitment is few.
