Description

Parking device of oil pumping unit Technical Field The utility model relates to the technical field of parking devices, in particular to a pumping unit parking device. Background The brake of the beam pumping unit mainly comprises two major types, namely external holding type and internal expanding type, the parking of the pumping unit is realized by utilizing a friction pair, and the friction pair and a brake wheel are normally worn and a brake connecting rod mechanism is deformed along with the increase of the service life, so that the brake moment is reduced, an operator only carries out braking by a conventional brake device in the construction operation process of the pumping unit after the beam pumping unit is stopped, and the pumping unit vibrates due to the oil well load change, well repairing operation, pumping unit maintenance, crank pin assembly replacement and the like during the construction operation of the pumping unit, so that the friction pair of the pumping unit brakes easily slides, and unexpected movement of the pumping unit is caused, and therefore, an oilfield unit continuously develops some auxiliary brake devices for the safety. For example, the utility model patent with the Chinese patent publication number of CN214945914U discloses a special-shaped tooth safety parking device of a beam pumping unit, which comprises a braking mechanism, a transmission mechanism and a driving mechanism, wherein the braking mechanism comprises a braking disc and a braking arm, disc braking teeth are uniformly fixed on the outer edge of the braking disc, the disc braking teeth are special-shaped teeth and comprise tooth bodies, the side surfaces of the tooth bodies comprise tooth top edges, tooth middle edges and tooth lower edges, the top parts of the tooth top edges are intersected to form sharp tooth tops, the tooth middle edges are inclined inwards, the tooth top edges and the tooth lower edges form obtuse angles with the tooth middle edges, a braking tooth block is arranged at the lower part of the braking arm, the braking tooth block comprises a braking base plate and arm braking teeth, and the arm braking teeth are special-shaped teeth matched with the disc braking teeth. Above-mentioned prior art realizes the mechanism auto-lock through designing the braking tooth into special-shaped tooth, but the device during operation need rotate rotatory rocking arm, and drive lead screw drives the drive tie rod, consequently consumes more time, has reduced work efficiency to the practicality is relatively poor. Disclosure of utility model (One) solving the technical problems In order to solve the technical problems, the utility model provides the parking device of the oil pumping unit, which is convenient for braking, improves the working efficiency and enhances the practicability. (II) technical scheme The parking device for the oil pumping machine comprises an oil pumping machine body, wherein brake wheels are arranged on the oil pumping machine body, the parking mechanism comprises an electric push rod, the electric push rod is fixedly arranged on the oil pumping machine body, a top plate is fixedly arranged at the output end of the electric push rod, two connecting cylinders are hinged to the top plate, two brake shoes are hinged to the oil pumping machine body, connecting columns are hinged to the two brake shoes, the two connecting columns are respectively connected with the two connecting cylinders in a sliding mode, limit grooves are formed in the two connecting cylinders, limit blocks are fixedly arranged on the two connecting columns, the two limit blocks respectively slide through the two limit grooves, springs are sleeved on the two connecting columns, a power supply and a controller are arranged on the oil pumping machine body, the electric push rod, the power supply and the controller are electrically connected, and the locking mechanism is arranged on the top plate and used for locking the brake wheels after parking.
