Abstract
The invention discloses an automatic expansion tightening mechanism for a belt of a pumping unit of an oil well. A belt expansion tightening wheel is connected with a pressure sensor which can control a servo motor to rotate, and the servo motor drives a screw rod to rotate through a reduction gear so as to drive the expansion tightening wheel to press a belt wheel tight. The automatic expansion tightening mechanism for the belt of the pumping unit can reduce the labor intensity of workers for expanding and the tightening the belt, and simultaneously overcomes the defects that the existing belt expansion tightening mechanism is unreliable in working and has larger errors on expansion tightening force.
Description
Technical field
The present invention relates to a kind of belt tension mechanism, particularly a kind of pumping unit of well belt automatic tension mechanism belongs to the oil field equipment technical field.
Background technique
Oil is as strategic materials and industrial blood, countries in the world are all dropped into huge fund and are developed and improve its output, along with fast development of Chinese economy, the consumption of oil heightens day by day, wants to make China's Oil to integrate with the world market, the consumption reduction high yield, it is imperative to improve crude output, for the oil recovery factory, must improve the oil recovery ability, guarantee high yield, the stable yields of recovering the oil.
Summary of the invention
The pumping unit in present oil field, big because of loading, the service time of belt, not long just belt the elongation fluffed, cause pumping unit idle running, directly influence the oil recovery ability in oil field, and the loss and waste of belt is serious, particularly oil well is dark, the viscosity of oil is big, contains the high oil well of cured amount and has above problem more; In case more serious problem is belt slippage idle running, the oil well pump of oil well can't be in time extracted crude oil out, oil pick-up tube takes place stop up the down-hole pumping unit is damaged, and causes the loss of several ten thousand yuan even hundreds of thousands unit, clear up the maintenance underground equipment with time-consuming consumption wealth, certainly will make the crude oil underproduction.
The tightness of present domestic solution belt, mainly be to patrol and examine and manually adjust the degree of tightness that motor is adjusted belt by timing, so just increased labor intensity, run into night, sleet sky, artificial adjustment is also just difficult especially, because the oil well distribution disperses, scope is wide, oil well idle running can only lean on artificial patrolling inspection just can learn, so, adjust also untimely, for overcoming this defective, some belt of oil pumping machine automatic tension mechanisms have been developed at present, but existing belt automatic tension mechanism exists work unreliable to a certain extent, the defective that the expanding force error is bigger.
The objective of the invention is to: a kind of pumping unit of well belt automatic tension mechanism is provided, with labor intensity and the existing difficulty that alleviates artificial tensioner belt, simultaneously, also be in order to overcome the defective that the existing work of existing belt tension mechanism is unreliable, the expanding force error is bigger.
The present invention realizes that the technological scheme that above-mentioned purpose adopts is: a kind of pumping unit of well belt automatic tension mechanism, it is the orientation that fixed base is fixed on close belt one side, install and fix guide rail above the fixed base, slide guide is installed above the fixed guide, slide guide has the degrees of freedom of sliding along the guide direction of fixed guide, on slide guide, install and fix retarder, actuating motor and retarder install and fix together, on the fixed base of fixed guide one end, vertically install and fix supporting, feed screw nut is fixed on above the fixed bearing, simultaneously, the axis of feed screw nut and the axis of reducer output shaft are on the same line, described leading screw is installed in the feed screw nut in the mode of screw-thread fit, one end of screw mandrel is fixed by the output shaft coupling of coupling and retarder, described sliding bearing is fixed on above the fixed base in fixed bearing left side by bearing support, and the axis of sliding bearing and leading screw are in above the same line, a sliding axle is installed in sliding bearing, sliding axle has the degrees of freedom that the slide relative bearing slides, and an end of sliding axle is connected and fixed by the left end of pressure transducer and leading screw.An other end and expansion tightening wheel are hinged, and described expansion tightening wheel tightly is being pressed in above the belt at ordinary times.
Working principle of the present invention is: at ordinary times, belt passes to pressure transducer to the pressure of expansion tightening wheel by sliding axle, when pressure reduces, illustrates that belt is in lax state; Pressure transducer just passes to actuating motor with control signal, and actuating motor just begins to start, when belt tension after the value of regulation, pressure transducer is given actuating motor with pressure signal transmission again, actuating motor shuts down.
Beneficial effect: automatic tension of the present invention mechanism, can alleviate the labor intensity and the existing difficulty of artificial tensioner belt, simultaneously, also overcome the defective that the existing work of existing belt tension mechanism is unreliable, the expanding force error is bigger.
