Background technology
To ensure that pumping unit pumping velocity and oil field stratum produce the synchronous compatibility of liquid, operating personnel must frequently adjust beam type
The jig frequency of pumping unit, to ensure the beam-pumping unit jig frequency of continuously exploitation and steady production, especially new well and low yield energy well, to oil well
Exploitation it is very crucial.New well crude oil water containing and Liquid output variation are relatively frequently, it is necessary to constantly adjust beam-pumping unit jig frequency；Middle and later periods opens
The oil field adopted is largely low liquid producing well, it is necessary to which low jig frequency or ultralow jig frequency (1.5 beats/min) just can ensure that continuous production.
Method currently used for adjusting beam-pumping unit jig frequency mainly has several：First, replace the motor skin of different-diameter
Belt wheel, and then realize reduction ratio variation, but since motor replacement belt pulley labor intensity is larger, and diameter can not be less than Φ
140 millimeters, because belt physical life and transmission efficiency will be seriously affected with the diminution of diameter pulley；Second is that use pole-changing
Formula multiple-speed motor makes customization line circle form different numbers of poles or two sets is distributed in stator coil not by different connections
With the coil of number of poles, generally using the pole mixing of the pole of 6 poles/8 or 8 poles/12, but since the speed of pole-changing adjustment is limited, also reduce
It is very limited to meet crude oil production condition for the power capacity of motor；Third, special converter is installed to pumping unit, by adjusting
Frequency converter output frequency changes the output revolutions of motor, and then realizes a variety of jig frequencies requirement of pumping unit, but due to frequency conversion
Device is continuously run in the wild for a long time, and often transducer element is damaged caused by sleet or strong wind weather, and if frequency converter
It operates at low frequency for a long time, the efficiency of motor can become very low, (not only added the in-fighting of frequency converter, but also seriously affected electricity
The power factor of net) maintenance cost of frequency converter long-time service is also very high, and each oil field is caused gradually to reduce pumping unit frequency converter
Usage quantity.

Description of the drawings
Fig. 1 is the overall structure diagram of the embodiment of the present invention；
Fig. 2 is the sliding slot of the embodiment of the present invention and the cross-sectional view of adjusting slider.
Specific embodiment
Pumping unit multispeed power assembly provided by the embodiment, basic scheme are：Subtracted by motor and manual shift multi gear
The compositions such as fast machine.Wherein, multi gear speed reducer does driving parts using synchronizing jugged belt pulley and synchronous belt, for ease of gear shift, institute
There are belt pulley, pinch roller using unilateral support pattern, i.e., the bearing support of wheel shaft is all in the one side of belt wheel.
Its overall structure is as shown in Figure 1：
Including：Engine base 1, L-shaped, bottom is pedestal, the front of side plate be equipped with drive pulley 3 shaft and from
The shaft of dynamic belt pulley 6, the back side of side plate are equipped with motor 8 and power output shaft 7,；The shaft of the drive pulley 3 with
The output shaft of motor 8 is connected；Drive pulley 3 is transferred power to described dynamic with driven pulley 6 by synchronizing jugged belt 4
Power output shaft 7.
The shaft of the drive pulley 3 and the shaft of driven pulley 6 are using uniaxial support, in order to gear shift and more
Change belt.
In order to ensure in the running, synchronizing jugged belt 4 has suitable tensioning with drive pulley 3 and driven pulley 6
Power, the present embodiment employ the pinch roller 2 of an adjustable-tightness.Driving motor in view of pumping unit is all usually a side
To rotation, the tension on belt that this pumping unit multispeed power total performance is upside is corresponded to, so pinch roller 2 should be mounted on downside
Below belt or above upper belt, in the present embodiment, pinch roller 2 should be mounted below the belt of downside.
Shown in referring also to Fig. 1 and Fig. 2, the front of the side plate is additionally provided with vertical chute 10, and the upper end of the sliding slot 10 is set
There is pinch roller tensioning nut 5, lower end is connected with the pinch roller 2, and a belt wheel adjusting slider 9 passes through along the sliding slot 10
The rotation of pinch roller tensioning nut 5 moves up and down.And the adjusting of pinch roller 2 is exactly based on and loosens or tighten pinch roller tensioning spiral shell
Mother 5, makes the vertical chute of belt wheel adjusting slider 9 along 1 side plate of engine base reach the standard grade and moves what is realized.The vertical chute 10
Section configuration with the belt wheel adjusting slider 9 can be common dovetail, but be with belt wheel adjusting slider 9
Example, preferably be embedded in the sliding slot 10 in part circular and mouth (handle) portion be parallel surface, see Fig. 2, essence can be met by so doing
The requirement really slided, and can be processed by simply boring miller skill.
Before work, first unscrew pinch roller tensioning nut 5, loosen pinch roller 2；Further according to DP technology requirement by manually will
Belt hangs over suitable belt pulley to upper；Then pinch roller tensioning nut 5 is tightened again, makes pinch roller 2 by belt tension；Finally
Can be powered operating.
The motor 8 of the present embodiment is fixed rotating speed motor, general usable common phase asynchronous induction machine, but in order to
It is preferably energy saving, it can be used that power factor is higher, the smaller self-start permanent magnet synchronous without frequency converter of no-load loss.
Since the present embodiment employs synchronizing jugged belt 4, the slippages of energy are less, compared to gear reduction box, knot
Structure is simpler, and accuracy of manufacture requirement is relatively low, and processing cost is relatively low, moreover, non-between belt and belt wheel contact firmly, without profit
Sliding, noise is also substantially reduced than gear drive.
The synchronizing jugged belt pulley of the present embodiment can use a variety of single including drive pulley 3 and driven pulley 6
Part, but preferably with the multistage combined overall structure of hot investment casting, so can not only reduce number of parts, more can letter
Makeup is matched somebody with somebody, and improves production efficiency.
Due to synchronizing jugged Pulley shaft, i.e. the wheel shaft of the wheel shaft of drive pulley and driven pulley 6 is duplex bearing branch
Support structure should use flexible connection, it is also possible to which using single bearing structure, i.e. motor does not have fore bearing, described electronic with motor 8
The output shaft of machine 8 is directly plugged on by spline in the shaft of the drive pulley 3.
Motor 8 in the present invention is fixed rotating speed motor, general usable common phase asynchronous induction machine, but in order to
It is preferably energy saving, it can be used that power factor is higher, the smaller self-start permanent magnet synchronous without frequency converter of no-load loss.
It should be pointed out that for those of ordinary skill in the art, without departing from the inventive concept of the premise,
Various modifications and improvements can be made, these belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention
It should be determined by the appended claims.
