| description | The utility model relates to an enclosed horsehead device of an oil pumping unit. The enclosed horsehead device of the oil pumping unit comprises horsehead side plates, a cambered plate, rib plates, a rope protection ring and a groove. The two parallel horsehead side plates are perpendicularly welded with the cambered plate. The radius of the cambered surface of the cambered plate is equal to the revolution radius of a horsehead. The width of the cambered plate is larger than the width between the two parallel horsehead side plates. The cambered plate is provided with the groove arranged in the middle part along the length direction. The rib plates are arranged between the two horsehead side plates. The rib plates are perpendicularly welded with the horsehead side plates and perpendicularly welded with the cambered plate. The rope protection ring is arranged at two sides of the horsehead side plates. The rope protection ring comprises a circular tube, a piece of angle iron and an arched guard ring. The angle iron is welded to two sides of the horsehead side plates. The circular tube is welded into the angle iron. Two ends of the arched guard ring are respectively welded with the circular tube. The enclosed horsehead device of the oil pumping unit is simple in structure and manufacturing, the use quantity of the rib plates is reduced, and compared with an oil pumping unit with the same stroke and polished rod load, about two thirds of the rib plates can be saved, so that the production cost is lowered. |
