The invention discloses a tower-type dual-chain belt oil pumping unit, which comprises a tower and a reciprocating weight belt, wherein the top part of the tower is provided with a first belt roller and a second belt roller, which are spaced in parallel, the tower at the side of the second belt roller is provided with a vertical cabin, and the side surface of the tower at the side of the first belt roller is provided with a windproof lead rail which extends in the vertical direction; and the reciprocating weight belt is bridged over the first and second belt rollers and comprises an inner side end which is located inside the cabin of the tower and an outer side end which extends at the outer side of the tower, wherein the outer side end is provided with a rope suspension device for being connected with an oil pumping rod, the rope suspension device is provided with a guide wheel which is matched with the windproof lead rail, a balance box, a first chain transmission mechanism and a second chain transmission mechanism are arranged inside the cabin, the balance box is connected with the inner side end of the weight belt, and the first and the second chain transmission mechanisms drive the balance box to ascend and descend. By adopting a four-column tower structure, the stability of the device can be greatly improved, the influence of wind load on the oil pumping process can be avoided, and the reliability of the device can be improved.
Description
technical field [0001] The invention relates to a pumping unit for oil production in an oil field, in particular to a tower type double chain belt pumping unit. Background technique [0002] Belt pumping unit is a low-stroke, long-stroke, heavy-duty surface oil production equipment, which can meet various working conditions of oil wells. It has the characteristics of high efficiency, safety, reliability and energy saving. application. [0003] The belt pumping unit includes a base, a frame erected on the base, a load-bearing belt supported on the rollers on the top of the frame, a balance box connected to the inner end of the load-bearing belt, a rope hanger connected to the outer end of the load-bearing belt, A chain transmission mechanism that drives the balance box, and a motor and a reducer that drive the chain transmission mechanism. [0004] Compared with the single-chain transmission mechanism, the double-chain transmission mechanism has the same direction of the dr...
