Abstract
The utility model relates to a belt automatic tensioner, in particular to a belt automatic tensioner for tensioning oil well pumping unit. The utility model comprises a housing, a transmission mechanism, a connecting rod, a bearing holder, a pressing arm, a rolling wheel, a spring regulator, a photoelectric pressure sensor, and a control power. When in use, the utility model is arranged on the ground surface under the oil well pumping unit belt or on a frame, which can make the belt in an optimum tensioning state and reduce the frequency of stroke with lowering the labor intensity of the people.
Description
Technical field
The present invention relates to a kind of belt tension mechanism, particularly a kind ofly be used for the belt automatic tension device that the tensioner pumping unit of well is used.
Background technique
What all fluff after belt work a period of time of using on the oil-field oil pumper at present, cause pumping unit idle running, directly influence the oil recovery ability in oil field, the method that solves is: one, more renew belt, two, manually reconcile distance between driving wheel and the driven wheel, so not only waste manpower, also increased working strength of workers simultaneously.
Summary of the invention
In order to overcome the deficiencies in the prior art, the objective of the invention is to propose a kind of automatic belt tension device that can address the above problem, the tightness by automatic belt tension device adjustment belt makes belt be in best tensioner state all the time, reduce the jig frequency loss, reduce labor intensity.
The object of the present invention is achieved like this: a kind of automatic belt tension device is made up of: frame, driving mechanism, connecting rod, bearing support, pressure arm, roller, spring-loaded governor, photovoltage force transducer, control power supply.Reducing motor, screw mandrel, feed screw nut form driving mechanism, are installed in respectively together in the frame separately on the position with bearing support, and bearing support is connected in hinged way with frame, and they are the pivot pin structure; At the top of bearing support back, be provided with pressure arm, for improving expanding force, the pressure arm design has the α angle, the α angular range is between 90-180 °, front end connects roller, keep a β angle between pressure arm and the bearing support for making, one of pressure arm bottom design has the protruding seat of axis hole, tripping arm bottom, axis hole center spacing dimension A on the protruding seat greater than the axis hole center on the bearing support from bearing support top spacing dimension B, axis hole place at protruding seat connects the same bearing support of pressure arm, connecting rod with pivot pin, and they are the pivot pin structure, can rotate mutually between the three; Connecting rod one end is hinged on the pressure arm, and the other end is the connecting filament stem nut in hinged way; On pressure arm and bearing support, a pair of perforation is arranged, the mounting spring regulator, spring-loaded governor is made up of spring, spring regulating lever, nut; The photoelectricity pressure inductor is arranged on the rearward end of pressure arm, holds out against pressure arm, is fixed on the bearing support, and control control power connection reducing motor is opened or closed.
The beneficial effects of the utility model: belt automatic tension device has replaced the work of manual conciliation belt, has alleviated working strength of workers, has improved mechanical efficiency.Cause the motor wheel because of the belt pine when particularly having solved oil-field oil pumper work and throw switch, actual jig frequency does not reach theoretical jig frequency and then influences the economic loss that oil output causes.
