At present, the sucker-rod pumping equipment that oil field is commonly used is beam pumping unit, in order to reduce the stressed of oil pumper driver part and reduce reducer moment of torsion and power of motor, needs on crank or walking beam, to increase balance weight to balance oil well load.Because oil well load often changes, therefore, balance weight need adjust in time, and existing adjusting balance of beam type oil pump is taked manually to adjust mode substantially, there is problems such as adjusting not in time, regulation time is long, adjustment workload is large.
Utility model content
The purpose of this utility model is to provide a kind of automatic adjusting balance beam-pumping unit, realizes oil pumper Automatic Balance Regulation, has in time, accurately, saves time and the feature such as laborsaving.
The purpose of this utility model realizes by following technical measures:
This automatic adjusting balance beam-pumping unit comprises walking beam, crank, reductor, mair motor, be hinged in frame in the middle of described walking beam, described mair motor is connected with reductor input, be hinged by connecting rod between walking beam rear end and crank, the crank other end is connected with the output of reductor, horse head is installed in walking beam front end, described crank is provided with automatic balancing device, described automatic balancing device comprises stable equilibrium block, move left balance weight, move right balance weight, balance motor, right-angle reduction device, described stable equilibrium block is connected by bolt with crank, and stable equilibrium block can slide along crank length direction on crank, described right-angle reduction device is connected with balance motor, and right-angle reduction device is arranged on stable equilibrium block, described right-angle reduction device two sides all have output shaft and rotation direction is contrary, describedly move left balance weight, the balance weight that moves right is arranged on the output shaft of right-angle reduction device two sides respectively.
The purpose of this utility model also realizes by following technical measures:
Described stable equilibrium blocks design is semicircle, and right-angle reduction device is arranged on by home position; Described balance motor is connected by shaft coupling with right-angle reduction device; Described shaft coupling has automatic deflection adjusting function; Described right-angle reduction device is connected with left and right mobile balanced block by key, and left and right mobile balanced block can around right-angle reduction device output shaft rotation.
The utility model has following beneficial effect:
The utility model carrys out mobile balanced block by balance motor, realizes the automatic adjustment of beam-pumping unit balance.Stable equilibrium block is connected by bolt with beam-pumping unit crank, and stable equilibrium block can slide along crank length direction on crank.Stable equilibrium blocks design is semicircle, replaces former beam-pumping unit two balance weights.It is inner that mobile balanced block, right-angle reduction device, balance motor are fixed on stable equilibrium block.Balance motor is connected by shaft coupling with right-angle reduction device, and described shaft coupling has automatic deflection adjusting function.Right-angle reduction utensil has dual output function, and two output shaft direction of rotation are contrary.Right-angle reduction device is connected with left and right mobile balanced block by key, and left and right mobile balanced block can around right-angle reduction device output shaft rotation.
When beam-pumping unit needs adjustment balance, start balance motor, balance motor transmits power to right-angle reduction device, and right-angle reduction device drives left and right mobile balanced block to rotate, and regulates beam-pumping unit to balance by changing left and right mobile balanced block position of centre of gravity.The utility model can realize beam-pumping unit automatic adjusting balance, has both improve production timeliness, has alleviated labor strength again, extends the application life of oil pumper.
