Abstract
A single crank double stroke flexible beam-pumping unit braking device solves the main problem of the large braking force needed by existing beam-pumping machine. The utility model is characterized in that a braking wheel (3) is connected with the rear of the axis of the electric engine (1), that two semi-sphere braking hoops (4) are arranged on the lower gemels of the braking wheel (3) on the rear of the bracket (2), that the gemels (4) is arranged on the exterior surface of the braking wheel (3), that the gemels (4) are connected with each other through the bolts (7) on the top, that springs are arranged on the bolts (7) and between the two braking gemels (4), and that the bolts (7) is connected with the braking handle (6) in pin joint with the bracket (2) through the triangle joining board (8) in pin connection with the bracket, the direction changing device (9) and the joining rod (5). The single crank double stroke flexible beam-pumping unit is of small braking force, simple structure and convenient application.
Description
Technical field:
The utility model relates to the used braking device of pumping unit, especially single-crank multiple-stroke flexible type pumping unit braking device in the oil recovery field, oil field.
Background technique:
Along with Oilfield developing, technology constantly develops, mechanical oil recovery equip ment from the beam pumping unit to the submersible electric pump, screw pump etc., of a great variety, to adapt to the needs of different productive lives.At present, the pumping unit that is used for artificial lift is based on beam pumping unit, is divided into conventional type beam pumping unit, prefix type beam pumping unit, out-phase type beam pumping unit and two horse head type beam pumping unit according to the difference of the structure of the crank quadratic crank mechanism of horse head.The pumping unit braking device of this structural type is big because of the reducer output shaft moment of torsion, just need big braking force unit could be stopped during braking, braking force hour can't be stopped unit, and it is poor so just to exist braking effect, dangerous, be unfavorable for applying.
The model utility content:
In order to solve the existing big problem of the required braking force of pumping unit, the utility model provides a kind of single-crank multiple-stroke flexible type pumping unit braking device, little, simple in structure, easy to use characteristics that this single-crank multiple-stroke flexible type pumping unit braking device has braking force.
The technical solution of the utility model is: this single-crank multiple-stroke flexible type pumping unit braking device comprises support and motor, the motor shaft rear end is connected with brake wheel, hinge has two semicircle brake hoops under the back-end support brake wheel, the brake hoop places the brake wheel outer surface, brake hoop upper end links together by bolt, be equipped with spring between two brake hoops on the bolt, bolt is connected with the brake handle of hinge on support by triangle connecting plate, the steering gear and the connecting rod of support upper hinge.
The utlity model has following beneficial effect: this single-crank multiple-stroke flexible type pumping unit braking device is owing to take such scheme, brake wheel directly is connected on the motor shaft, because of the output torque of motor rear axle little, so braking force directly acts on the motor shaft, required like this braking force is just little, just unit can be stopped under less moment, has improved braking effect, eliminated potential safety hazard, helped applying.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is right elevations of Fig. 1.
1-motor among the figure, 2-support, 3-brake wheel, the 4-hoop that brakes, 5-connecting rod, 6-brake, 7-bolt, 8-triangle connecting plate, 9-the steering gear.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
This single-crank multiple-stroke flexible type pumping unit braking device comprises support 2 and motor 1, by shown in Figure 2, motor 1 shaft rear end is connected with brake wheel 3,3 times hinges of support 2 rear end brake wheels have two semicircle brake hoops 4, brake hoop 4 places brake wheel 3 outer surfaces, brake hoop 4 upper ends link together by bolt 7, two 4 on brake hoops are equipped with spring on the bolt 7, in conjunction with shown in Figure 2, bolt 7 is connected 6 with the brake of hinge on support 2 by triangle connecting plate 8, the steering gear 9 and the connecting rod 5 of support 2 upper hinges by Fig. 1.By Fig. 1 in conjunction with shown in Figure 2, by moving brake left 6, brake spurs bolts 7 to 6 by connecting rod 5, the steering gear 9, connecting rod 5 and triangle connecting plate 8, bolt 7 pulling springs and two brake hoops 4 shrink, two brake hoops 4 hug and produce friction with brake wheel 3 outer surfaces, motor is stopped operating, pumping unit is stopped operating.Because of brake wheel 3 directly is connected on motor 1 rear axle, the output torque of motor 1 rear axle is little, so braking force directly acts on 1 in the motor, required like this braking force is just little, under less moment, just unit can be stopped, improved braking effect, eliminated potential safety hazard, helped applying.
Claims (1)
1, a kind of single-crank multiple-stroke flexible type pumping unit braking device, comprise support (2) and motor (1), it is characterized in that: motor (1) shaft rear end is connected with brake wheel (3), support (2) rear end brake wheel (3) hinge down has two semicircle brake hoops (4), brake hoop (4) places brake wheel (3) outer surface, brake hoop (4) upper end links together by bolt (7), be equipped with spring between the last two brake hoops (4) of bolt (7), bolt (7) is by the triangle connecting plate (8) of support (2) upper hinge, the steering gear (9) and connecting rod (5) are connected (6) with the brake of hinge on support (2).
