Description
Technical field
The utility model relates to the field mining equipment technical field, is the counter balance torque self-checking device of beam-balanced pumping unit.
Background technology
At home and abroad in the oil extraction in oil field engineering, mechanical oil recovery equip ment commonly used is beam pumping unit at present.Beam pumping unit because simple in structure, use reliable, convenient operating maintenance, the characteristics such as reliably and with long-term safe operation in abominable natural environment, it is widely used in oil extraction process, and what still adopted more than 90% in China oil field at present is beam pumping unit.The balance mode of beam pumping unit mainly contains two kinds: crank balance and beam balance.Balance moment of crank is the sinusoidal motion rule, and polished rod load moment is to depart from the sinusoidal characteristics of motion, so counterbalance effect and bad.Beam balance moment and the polished rod load moment characteristics of motion are in full accord, belong to uniformity characteristics of motion balance mode, so counterbalance effect is fine.Owing to the variation of polished rod load along with hole condition changes, trimming moment can't realize automatically regulating with the variation of polished rod load.In addition, because balance weight is arranged on the end of walking beam postbrachium, the adjusting of trimming moment bothers very much, must come adjustment moment by artificial plus-minus balance weight, and very dangerous.Therefore, design a kind of new device and can realize that the automatic adjusting of trimming moment is very important.
The utility model content
The purpose of this utility model provides a kind of counter balance torque self-checking device of beam-balanced pumping unit, overcomes the automatically heavy defective of adjustment of existing oil production equipment, makes automatically adjustment moment of torsion of beam-balanced pumping unit.
The technical solution of the utility model is the counter balance torque self-checking device of beam-balanced pumping unit, which comprises at least motor, reducer, swivel nut, push rod, guide pad, connecting rod, fork and balance weight, it is characterized in that: be fixed with motor on the walking beam postbrachium, motor output shaft is connected with the reducer input; Establish screw thread in the swivel nut, an end is connected with the output shaft of reducer, the other end by bearing be connected with externally threaded push rod, the end of push rod is connected with guide pad; Fork is fixedly connected with by the hinged end with the walking beam postbrachium in middle part, and can swing along the hinged place, and the lower end of fork is provided with balance weight, and the upper end of fork is hinged fixing by connecting rod and guide pad.
Described bearing is provided with bearing support, and bearing support is fixedly connected with the walking beam postbrachium.
The screw thread of described swivel nut and push rod is rectangular thread or trapezoidal thread.
Characteristics of the present utility model are that the counter balance torque self-checking device of this beam-balanced pumping unit is simple in structure, use is reliable, and can realize the automatic adjustment moment of torsion of beam-balanced pumping unit, do not use the manual adjustment balance weight, saved the labour, saved cost.
Description of drawings
Below in conjunction with the utility model is further described.
Fig. 1 is the structural representation of the counter balance torque self-checking device of beam-balanced pumping unit.
Among the figure: 1, motor; 2, reducer; 3, swivel nut; 4, bearing support; 5, push rod; 6, guide pad; 7, connecting rod; 8, fork; 9, balance weight; 10, walking beam postbrachium.
The specific embodiment
As shown in Figure 1, be fixed with motor 1 on the walking beam postbrachium, the output shaft of motor 1 is connected with the input of reducer 2, and motor 1 drives reducer 2, and the output shaft of reducer 2 is connected with an end of swivel nut 3.
Swivel nut 3 is provided with the internal thread of rectangle, and push rod 5 is provided with the external screw thread of rectangle, and swivel nut 3 is connected with push rod 5 by bearing, forms the screw thread transmission, and the end of push rod 5 is provided with guide pad 6.
Bearing is fixed on the walking beam postbrachium 10 by bearing support 4, and swivel nut 3 is played a supportive role.
The middle part of fork 8 and walking beam postbrachium 10 terminal hinged, the lower end of fork 8 is provided with balance weight 9, and its upper end is hinged by connecting rod 7 and guide pad 6.
During work, motor 1 is with the input of power transmission to reducer 2, through after the deceleration of reducer 2.Output shaft band movable snail sleeve 3 transmissions of reducer 2.
Because swivel nut 3 forms the screw thread transmission with push rod 5, so push rod 5 can elongate or shorten along the walking beam direction, do plane motion thereby promote connecting rod 7 by guide pad 6.
The middle part of fork 8 and walking beam postbrachium 10 are hinged fixing, the upper end is hinged fixing with connecting rod 7 again, under the drive of connecting rod 7, fork 8 is to carry out clockwise or counterclockwise rotation with the pin joint of walking beam postbrachium 10 as round dot, fork 8 and the angle of walking beam postbrachium 10 are changed, drive simultaneously the swing of lower end balance weight 9, realized the automatic adjusting of trimming moment.
Embodiment 2
The structure of present embodiment and embodiment 1 is basic identical, and different is, and the internal thread of swivel nut 3 and the external screw thread of push rod 5 adopt trapezoidal thread, and trapezoidal thread and rectangular thread can reach identical purpose, the automatic adjusting of realization trimming moment in this structure.
The parts that present embodiment is not described in detail and structure belong to well-known components and common structure or the conventional means of the industry, here not one by one narration.
