Abstract
The tight braking device of pumping unit, relates to pumping unit field.Comprise brake pin and be fixed on the brake wheel on input shaft of reduction gearbox of oil pumping unit, the ring week of described brake wheel is evenly equipped with a plurality of brake draw-in grooves, brake draw-in groove is the large isosceles trapezoid of outer young internal orifice, on the speed reducer of described brake wheel one side, be fixed with bearing pin, one end of described brake pin is placed through rotationally on bearing pin and by pad and cotter pin and fixes, the both sides of the brake pin the other end are respectively arranged with the triangle snap fit coordinating with the brake draw-in groove of brake wheel, and the triangle snap fit symmetrical reverse of both sides arranges.The utility model can well stop at horizontal position by walking beam in conjunction with oil-pump braking device while using.While taking out brake pin, judged motor sense of rotation, starting motor changes an angle, is separated from brake draw-in groove, without external force equipment such as cranes, takes out brake pin.
Description
Technical field
The utility model relates to pumping unit field, is specially a kind of tight braking device of pumping unit.
Background technique
1, beam pumping unit oil well operation, adjusts over-stroke, and the tight brake that all needs to stop when adjusting equilibrium block etc., for safety more and lock brake pin (tight braking).Because the reasons such as oil pumping body vibration, brake strap wearing and tearing cause brake loosening, become flexible to enter in brake wheel dovetail groove with rear braking pin card, brake wheel is fixed by locked, plays safety guarantee effect.
Operation, while having operated, need to lodge the external force equipment such as crane and brake pin could be taken out from the trapezoidal race of brake wheel, incur loss through delay oil well and opened and find time.Given this, the brake pin on oil pumping unit brake wheel always abandon and need not, be used as one " safety ornaments ", in work, just do not have safety guarantee effect.
2, superduty beam pumping unit, when orientation is braked, because braking device is not given power, particularly, when laying down pumping unit horsehead load, there will be the incessantly situation of car of stopping, and has incured loss through delay the work progress of oil well, can cause pumping unit horsehead difficulty to get rid of phenomenon etc.
Model utility content
The purpose of this utility model is to provide a kind of tight braking device of pumping unit, and this device is used in conjunction with oil-pump braking device while using, and without external force equipment such as cranes in the situation that, walking beam can well be stopped to desired location.
The technological scheme that realizes above-mentioned purpose is: the tight braking device of pumping unit, comprise brake pin and be fixed on the brake wheel on input shaft of reduction gearbox of oil pumping unit, the ring week of described brake wheel is evenly equipped with a plurality of brake draw-in grooves, it is characterized in that: described brake draw-in groove is the large isosceles trapezoid of outer young internal orifice, on the speed reducer of described brake wheel one side, be fixed with bearing pin, one end of described brake pin is placed through rotationally on bearing pin and by pad and cotter pin and fixes, the both sides of the brake pin the other end are respectively arranged with the triangle snap fit coordinating with the brake draw-in groove of brake wheel, the triangle snap fit symmetrical reverse of both sides arranges.
The long limit of the triangle snap fit of described both sides is circular arc.
The utility model can well stop at horizontal position by walking beam in conjunction with oil-pump braking device while using.While taking out brake pin, judged motor sense of rotation, starting motor changes an angle, is separated from brake draw-in groove, without external force equipment such as cranes, takes out brake pin.
Solve to a certain extent pumping unit horsehead difficulty and got rid of phenomenon.
When people works on pumping unit body, directly brake pin card is entered in the brake draw-in groove on brake wheel, improve utilization ratio and the safety coefficient of brake pin, tight braking is being not safe ornaments.
Accompanying drawing explanation
Fig. 1 is brake wheel working state figure of the present utility model while clockwise rotating;
Fig. 2 is brake wheel working state figure of the present utility model while rotating counterclockwise;
The structural drawing that one end that Fig. 3 is brake pin is connected with speed reducer.
Embodiment
As shown in Figure 1, 2, 3, the utility model comprises brake pin 1 and is fixed on the brake wheel 3 on the input shaft of oil pumping unit reduction gearbox 2, and the ring week of brake wheel 3 is evenly equipped with a plurality of brake draw-in grooves 4, and brake draw-in groove 4 is the large isosceles trapezoid of outer young internal orifice.
On the speed reducer of brake wheel 2 one sides, be fixed with bearing pin 5, one end of brake pin 1 is placed through rotationally on bearing pin 5 and by pad 6 and cotter pin 7 and fixes, the both sides of brake pin 1 the other end are respectively arranged with the triangle snap fit 8 that the long limit that coordinates with the brake draw-in groove 4 of brake wheel 3 is circular arc, the triangle snap fit 8 symmetrical reverse settings of both sides.
As shown in Figure 1, when brake wheel 3 is rotated counterclockwise motion under motor drives, brake pin 1 is inoperative, and during clockwise slow circumvolve, brake pin 1 works and the locked brake wheel 3 of fixing.
As shown in Figure 2, when brake wheel 3 is made clockwise rotation under motor drives, brake pin 1 is inoperative, and during counterclockwise slow circumvolve, brake pin 1 works and the locked brake wheel 3 of fixing.
The utility model, according to the stand of oil pumping machine crank, by brake is sold to putting of 1 positive and negative two sides, can complete the locked of brake wheel 3 fixed in conjunction with oil-pump braking device, plays safety guarantee effect.
Take out brake pin at 1 o'clock, judged motor sense of rotation, starting motor changes an angle, makes brake pin 1 be separated from brake draw-in groove 4, without external force equipment such as cranes, takes out brake pin 1.
Claims (2)
1. the tight braking device of pumping unit, comprise brake pin and be fixed on the brake wheel on input shaft of reduction gearbox of oil pumping unit, the ring week of described brake wheel is evenly equipped with a plurality of brake draw-in grooves, it is characterized in that: described brake draw-in groove is the large isosceles trapezoid of outer young internal orifice, on the speed reducer of described brake wheel one side, be fixed with bearing pin, one end of described brake pin is placed through rotationally on bearing pin and by pad and cotter pin and fixes, the both sides of the brake pin the other end are respectively arranged with the triangle snap fit coordinating with the brake draw-in groove of brake wheel, and the triangle snap fit symmetrical reverse of both sides arranges.
