Abstract
The utility model discloses a brake device for an oil pumping unit, which is used in oil industry and aims to enable the braking process of the oil pumping unit to be labor-saving and reliable. The device comprises two brake hoops; the upper ends of the two brake hoops are hinged through a screw rod fixed on a reduction gearbox of the oil pumping unit; the device is further provided with a rocking lever and a rocking lever bracket; screw holes are formed at the lower ends of the two brake hoops, and threads in the screw holes are reverse threads; the rocking lever is mounted on the rocking lever bracket, wherein a rocking handle is arranged at one end of the rocking lever, and threads and a positioning ring are mounted at the other end; threads on the two sides of the positioning ring are reverse threads; and the two brake hoops are mounted on two sides of the positioning ring. When in rotation, the rocking lever drives the two ends of the two brake hoops to be folded and unfolded along the reverse threads on the rocking lever, so that braking of the oil pumping unit is realized; besides, the braking process is labor-saving, the combination is tighter, and safety and reliability are achieved; and consequences caused by untightness in combination of the brake hoops can be avoided. The brake device has the advantages of simple structure, easiness in manufacturing, reliability in working, and better use values.
Description
Technical field
The utility model relates to the oil-pump braking device of petroleum industry, and particularly a kind of oil-pump braking device, make oil pumping unit brake laborsaving, reliable.
Background technique
The braking device of petroleum industry pumping unit is the locking hood type braking device at present, is locking hood type by two brake ferrules and strains the realization brake by pull bar, generally is difficult to stop dead.By the investigation and analysis to oil-pump braking device, find that the brake principle is all that pull bar is eccentric, under the state of getting off the brakes, all there are friction in various degree in brake strap and wheel, and the brake ferrule opening and closing are uneven, the brake block eccentric wear, due to oil pumping unit brake band and wheel long term wear, brake strap is formed groove, even disconnects by eccentric wear, causes brake failure, and during brake, pumping unit horsehead can not be parked in preposition.After getting off the brakes, brake again, even brake out of control, has the brake potential safety hazard of hurting sb.'s feelings that causes out of control suddenly.At present, oil-pump braking device is under the state of getting off the brakes, and all there are in various degree friction in brake strap and wheel, causes the pumping unit power consumption to increase, and test draws, and transmission system efficiency reduces by 4% left and right, the average individual well power consumption 11kWh that increases day by day; Simultaneously, due to brake ferrule Zhang Bukai, Zhang Bujun, the brake block eccentric wear, brake failure also can cause the suddenly problem such as hurt sb.'s feelings out of control.
Summary of the invention
The purpose of this utility model is to provide a kind of oil-pump braking device, for the deficiencies in the prior art, provides a kind of safe and reliable braking device, the adverse consequences of avoiding brake failure to bring.
For solving this technical problem, the utility model provides a kind of oil-pump braking device to comprise two brake ferrules, and the upper end of two brake ferrules is hinged by the screw rod that is fixed on oil pumping unit reduction gearbox.This device also is provided with rocking bar and rocker bracket, and the lower end of two brake ferrules is equipped with screw, and the screw thread in its screw is reverse thread; Rocking bar is arranged on rocker bracket, and an end is rocking handle, and the other end is provided with screw thread and positioning ring is housed, and the screw thread of positioning ring both sides is reverse threads, two brake ferrules is arranged on the both sides of positioning ring.The two ends that drive two brake ferrules when rocking bar rotates are tightened up or open along the reverse thread on rocking bar, realize oil pumping unit brake.
The beneficial effects of the utility model such as following: the utility model has compared with prior art adopted rocking bar and brake ferrule reverse thread brake anchor ear, and is easy to operate, makes brake laborsaving, and obvolvent is tighter, has more safety reliability.Can avoid the not next consequence of taut band of brake ferrule obvolvent, have obvious social benefit.This is practical simple in structure, easy to manufacture, and reliable operation has use value preferably.
Description of drawings
Accompanying drawing is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing in detail the utility model is described in detail, referring to accompanying drawing.A kind of oil-pump braking device comprises that the upper end of 3, two brake ferrules 3 of two brake ferrules is hinged by the screw rod that is fixed on oil pumping unit reduction gearbox.The lower end that this device also is provided with rocking bar 2 and 4, two brake ferrules 3 of rocker bracket is equipped with screw, and the screw thread in its screw is reverse thread; Rocking bar 2 is arranged on rocker bracket 4, and an end is rocking handle 5, and the other end is provided with screw thread and positioning ring 6 is housed, and the screw thread of positioning ring 6 both sides is reverse threads, two brake ferrules 3 is arranged on the both sides of positioning ring 6.Set screw nut is installed at two ends at rocking bar 2 reverse threads, is that two brake ferrules 3 are spacing.Rocking bar 2 comprises rocking handle bar and brake lever, and an end of rocking handle bar is rocking handle 5, and the other end of rocking handle bar is connected by box cupling with brake lever, facilitates the making processing of rocking bar 2 and installs.Rocker bracket 4 is fixed on oil pumping unit base 1, as by the welding or fix with bolt.
During use: shake rocking handle 5 and drive rocking bar 2 rotations, the lower end of brake ferrule 3 is moved inward, hold the oil pumping unit brake wheel tightly and realize brake.Oppositely shake rocking handle 5 and drive rocking bar 2 rotations, unclamp the oil pumping unit brake wheel, make the pumping unit normal operation.Owing to having adopted reverse thread brake anchor ear, make brake laborsaving, obvolvent is tighter, has safety reliability.
