Abstract
The utility model relates to a rocker arm type pumping unit reversing arrangement, which consists of an upper chain wheel, a chain, a lower chain wheel, a rocker arm, a piece of balance weight iron, a connecting shaft and a reversing shaft. The utility model is characterized in that the chain passes by the upper chain wheel and the lower chain wheel; the balance weight iron is arranged on the slideway positioned inside a box body through a fixed pulley; one end of the rocker arm is fixed with the balance weight iron through the connecting shaft, while the other end is fixed on the chain through the reversing shaft. The utility model has the advantages of simple processing technique, flexible motion, convenience for assembly and maintenance, reduction in the weight of a pumping rod and electricity conservation.
Description
Technical field
The utility model relates to the reversing arrangement of oil-field oil pumper, particularly a kind of rocking arm type pumping unit reversing arrangement.
Background technique
Existing pumping unit reversing arrangement is made up of reversing shaft, slide block, balladeur train, and ballast box slides in balladeur train, and it is dumb to move, the processing technology complexity, and precision is low, and cost is higher.
Summary of the invention
The purpose of this utility model provide a kind of simple in structure, rocking arm type pumping unit reversing arrangement flexibly moves.
Rocking arm type pumping unit reversing arrangement, this device is made up of upper sprocket wheel, chain, lower sprocket, rocking arm, balance weight iron, coupling shaft and reversing shaft, it is characterized in that: chain is walked around upper sprocket wheel and lower sprocket, balance weight iron by upper saw pulley be arranged on the slideway in the casing, rocking arm one end fixes by coupling shaft and balance weight iron, the other end is fixed on the chain by reversing shaft.
Described chain is a strand bar structure.
The utility model has the advantages that processing technology is simple, motion is flexible, easy to assembly, be convenient to maintenance; Alleviate rod weight, economize on electricity.
