Abstract
A pumping unit belt adjusting device comprises a belt, a pressing wheel, a sleeve, a spring, a telescopic shaft and an adjustable lateral lever, the pressing wheel is fixed under the belt, the sleeve is connected with the pressing wheel, the spring is provided in the sleeve, the adjustable lateral lever is fixed under the spring, the adjustable lateral lever is connected with the sleeve and is provided on one side of the sleeve. The belt is pressed tightly by the pressing wheel under the force of the spring, and the belt is in constant tension so as to increase the wrap angle between the belt and the belt wheel; the lateral lever can make a left-right adjustment of the press wheel in order to further adjust the tension degree of the belt and to avoid slipping between the belt and the belt wheel, moreover, the punching number of the oil pump for an oil well is free from reduction so as to maintain the oil well yield and to prevent the burning of the belt caused by the slipping of the belt which can result in the stop of production, and can prevent the losses.
Description
One, technical field
The utility model is the oil-field oil pumper controlling device, particularly a kind of belt of oil pumping machine controlling device.
Two, background technique
In order to improve pump efficiency, improve mechanical efficiency, reduce eccentric wear, the normal long stroke that adopts, the process data of low jig frequency, in order to reach the parameter production of low jig frequency, the on-the-spot method that reduces jig frequency is to turn motor pulley down, but after turning motor pulley down, the cornerite of belt on belt pulley reduces, and there are skidding in belt and belt pulley, because pumping unit is installed in the field, skidding is more serious during rainy day, gently then reduce the pumping unit jig frequency, reduce oil well output, heavy then cause the belt slippage scaling loss of generating heat not use, must stop production and change belt, economic loss is more serious.
Three, summary of the invention
The purpose of this utility model provides a kind of belt of oil pumping machine controlling device, makes it can the tensioning belt of oil pumping machine, avoids belt and belt pulley on the pumping unit skidding to occur, reduces oil well and stops production, and increases economic efficiency.
The purpose of this utility model is achieved in that by belt, pinch roller, sleeve, spring, telescopic shaft, lateral adjustments bar to be formed, and pinch roller is under the belt, and sleeve connects with pinch roller, and mounting spring in the sleeve is installed telescopic shaft under the spring.
The beneficial effects of the utility model are: under spring action, pinch roller compresses belt, belt has certain rate of tension all the time, increased the cornerite of belt and belt pulley, do not occur skidding between belt and the belt pulley, the oil well pump jig frequency of oil well can not fallen at the end, can not influence oil well output, can not cause oil well to stop production yet, avoid economic loss because of belt slippage causes the scaling loss of belt.
Four, description of drawings
Accompanying drawing is the utility model embodiment's a erection drawing.
Five, embodiment
Below in conjunction with accompanying drawing the utility model embodiment is described.
In the drawings: the 1st, belt, the 2nd, pinch roller, the 3rd, sleeve, the 4th, spring, the 5th, telescopic shaft, the 6th, lateral adjustments bar.Be that the utility model is made up of belt 1, pinch roller 2, sleeve 3, spring 4, telescopic shaft 5, lateral adjustments bar 6, pinch roller 2 is under the belt 1, sleeve 3 connects with pinch roller 2, mounting spring 4 in the sleeve 3, telescopic shaft 5 is installed under the spring 4, lateral adjustments bar 6 connects with sleeve 3, and is in the side of sleeve 3.Telescopic shaft 5 is fixed on the pumping unit motionless, and lateral adjustments bar 6 one ends connect with sleeve 3 sides, and the other end is fixed on the oil pumping unit base.
Pinch roller stream is pressed in belt 1 below, under the pretightening force effect of spring 4, make belt 1 below bending occur, thereby increase belt 1 through distance, increase belt 1 rate of tension, increase the contact cornerite of belt 1 at belt pulley, when the pretightening force of pumping unit process long-play rear spring 4 is not enough, can rotate the screw on the lateral adjustments bar 6, make belt 1 guarantee certain rate of tension all the time, make not occur skidding between belt 1 and the belt pulley.
