Abstract
The utility model relates to a balance weight moving tool of an oil pumping unit. The balance weight moving tool of the oil pumping unit is used for mechanical oil extraction in an oil field. The balance weight moving tool of the oil pumping unit comprises an oil pumping unit crank, a balance weight and a balance weight moving tool body, wherein a rack is arranged on the oil pumping unit crank, the balance weight is fixed on the oil pumping unit crank through bolts at the two ends, semicircular locking holes are formed in the two sides of the middle portion of a contact surface between the balance weight and the oil pumping unit crank respectively, and locking blocks are arranged in the locking holes. The balance weight moving tool of the oil pumping unit is characterized in that the balance weight moving tool body comprises a transmission gear and a handle, the handle is connected to the center of the transmission gear, and the transmission gear is clamped in the semicircular locking holes and is matched with the rack on the oil pumping unit crank. The balance weight moving tool of the oil pumping unit has the advantages that both time and labor are saved, labor intensity of operators is low, no danger exits during operation, the balance weight of the oil pumping unit can be moved to a needed position conveniently and fast, the work processing is not affected, and stopping time of the oil pumping unit in a well is shortened greatly.
Description
Technical field
The utility model relates to the counter weight of beam unit Move tool that a kind of oil field machinery oil is used.
Background technology
The balance weight of oil pumper needs often to adjust position; balance requirement in the time of could meeting the upper and lower stroke of oil pumper; adjust the position of balance weight and the balance weight of several tons of weights need to be moved to another one position; the method of current on-the-spot mobile balanced block is; first loosen balance weight fixed screw and lock dog screw; with crowbar, prize balance weight again; because balance weight has several tons of weights; therefore, prize very slowly, require great effort, operating personnel are dangerous large; easily cause personal injury; make shutdown of pumping machine time lengthening, delay production, affect oil well output.
Utility model content
The purpose of this utility model is to provide a kind of counter weight of beam unit Move tool, utilizes this counter weight of beam unit Move tool, can easily and efficiently counter weight of beam unit be moved to the position needing.
The technical scheme that realizes above-mentioned purpose is: counter weight of beam unit Move tool, comprise oil pumping machine crank, balance weight and balance weight Move tool, on oil pumping machine crank, be provided with tooth bar, balance weight is bolted on oil pumping machine crank by two ends, the both sides, middle part of balance weight and oil pumping machine crank contact surface are respectively arranged with semicircle lock hole, are provided with lock dog in lock hole; It is characterized in that: described balance weight Move tool comprises travelling gear and handle, one end of handle is connected to the center of travelling gear, travelling gear, for when mobile balanced block, is placed in lock hole, and the engagement of the tooth bar on travelling gear and oil pumping machine crank.
Described handle comprises intermediate bar, transition joint and boosting-rod, and intermediate bar is by transition joint and dismantled and assembled L shaped structure, the dismantled and assembled center that is connected to travelling gear of the other end of intermediate bar of being connected to form of boosting-rod.
In the time of need to adjusting balance, loosen the set bolt at balance weight two ends, take out the lock dog in lock hole, install handle and travelling gear, travelling gear is placed in lock hole, by on carry or press down handle, the movement with nutating gear on oil pumping machine crank tooth bar, realizes moving around of balance weight.
During due to turning handle, do not need very large strength.Therefore, counter weight of beam unit Move tool can reach purpose of design, time saving and energy saving, operating personnel's labour intensity is low, during operation, is safe from danger, and can easily and efficiently counter weight of beam unit be moved to the position needing, do not affect job schedule, greatly shortened stopping the well time of oil pumper.
