Description
Technical field
The utility model relates to oil pumper; Specifically a kind of electric reversing pumping unit.
Background technology
Along with deepening continuously and the continuous rising of moisture content of oil field development, also more and more higher to the requirement of oil pumper.Current field use oil pumper is mainly based on the mechanical reversing pumping unit that beam pumping unit and belt oil pumping machine are representative.Beam pumping unit and belt type pumping unit, can not meet the development requirement of oil field cost efficiency due to limitations such as energy consumption are high, consumptive material is many, mechanical efficiency is low; In recent years, electricity reversing pumping unit due to its transmission link of tool few, the development of efficiency high rapidly, mainly drive two kinds of forms with top drive and bottom, top drive motor and reducer difficult in maintenance, and top drive form Pumping Unit is huge, and operation is stepped down difficulty, cost is high, limits the large-scale promotion application of electric reversing pumping unit.
Utility model content
The purpose of this utility model is to provide a kind of electric reversing pumping unit, utilizes built-in type motorized pulleys reducer to realize slowing down and power transmission; Traction belts is forward and reverse to be wrapped in reducer cylinder is connected with polished rod and balance weight respectively and to realize balance of well pumping unit.
In order to reach above-mentioned purpose, the utility model have employed following technical scheme, a kind of electric reversing pumping unit, comprise frame, motor, reducer, first traction belts, second traction belts, described frame upper end arranges first day wheel respectively, second crown sheave, described motor is connected with the input of reducer by belt, described reducer output connects cylinder, described first traction belts, second traction belts lower end to be all wrapped on cylinder and mutually each other pros-and-cons type be wound around, the backward lower connecting with pumping rod of first day wheel is walked around in described first traction belts upper end, the backward lower connection balance weight of the second crown sheave is walked around in described second traction belts upper end.
Be fixed on base bottom described frame.Described motor and reducer are all fixed on base.
Described motor is switched reluctance machines.Described reducer is built-in type motorized pulleys reducers.
The described balance weight track that moves up and down is positioned at machine frame inside.
Compared to prior art, the utility model has following beneficial effect:
Motor, by belt pulley Direct driver built-in type motorized pulleys reducer, realizes slowing down and power transmission; First traction belts, the second traction belts be forward and reverse to be wrapped in reducer cylinder is connected with polished rod and balance weight respectively and to realize balance of well pumping unit.The utility model eliminates the structures such as special power drum, reducer base, reducer concrete pedestal, further reduces transmission link, improves transmission efficiency, and reduce cost; The mode that operation can adopt complete machine to drop back, has easy for installation, operation and to step down the advantage such as convenient and swift.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of electric reversing pumping unit of the present utility model.
In figure: first day wheel 1, second crown sheave 2, first traction belts 3, second traction belts 4, frame 5, built-in type motorized pulleys reducer 6, belt 7, switched reluctance machines 8, base 9, balance weight 10.
Detailed description of the invention
Relevant detailed description of the present utility model and technology contents, coordinate accompanying drawing to be described as follows, but accompanying drawing only provides with reference to the use with explanation, is not used for being limited the utility model.
According to Fig. 1, a kind of electric reversing pumping unit, comprises frame, motor, reducer, the first traction belts, the second traction belts, is fixed on base 9 bottom frame 5.Motor and reducer are all fixed on base.Motor is switched reluctance machines 8.Reducer is built-in type motorized pulleys reducer 6.Frame upper end arranges first day wheel 1, second crown sheave 2 respectively, motor is connected with the input of reducer by belt 7, reducer output connects cylinder, described first traction belts 3, second traction belts 4 lower end to be all wrapped on cylinder and mutually each other pros-and-cons type be wound around, the backward lower connecting with pumping rod of first day wheel is walked around in described first traction belts upper end, and the backward lower connection balance weight 10 of the second crown sheave is walked around in described second traction belts upper end.The balance weight track that moves up and down is positioned at machine frame inside.
Frame 5 lower end is fixedly connected with base 9; Switched reluctance machines 8 is arranged on respectively on base 9 with built-in type motorized pulleys reducer 6 and is connected by belt 7; First traction belts 3, second traction belts 4 is forward and reverse to be wrapped in and reducer cylinder walks around first day wheel 1, second crown sheave 2 to be respectively connected with polished rod and balance weight 10.Switched reluctance machines 8 rotating drives built-in type motorized pulleys reducer 6 by belt 7, is driving oil pumping polish rod to pump by the first traction belts 3, realizes oil pumping, and simultaneously the second traction belts 4 is connected with balance weight 10 and realizes balance of well pumping unit.
The foregoing is only preferred embodiment of the present utility model, be not used to limit the scope of the claims of the present utility model, other use the equivalence of patent spirit of the present utility model to change, and all should all belong to the scope of the claims of the present utility model.
