In addition, the real-time status of the entire process cannot be observed by humans, which is prone to accidents. Especially when the pipe laying machine receives the plug-in pipe, the plug-in pipe needs to be rotated from a vertical state to a horizontal state before it can be recovered by the pipe laying machine. In this process, it is difficult to effectively perform such operations manually because the plug-in pipe is too long.

[0003] Therefore, a sucker rod automation device is designed to solve the above problems. Utility Model Content

The end of the flip hydraulic cylinder 9 away from the flipping box 1 is fixedly connected with the cylinder front block 5, and the lower end of the cylinder front block 5 is provided with a flip hinge ear 7, and the flip hinge ear 7 is connected to the flip seat 4 through a pin shaft 8.

[0024] It should be noted that the model of the straight connector 10 is 12MDL-6MDG

[0025] The surface of the flip seat 4 is connected with a pin shaft 3 6, and the ends of the pin shaft 3 6 and the pin shaft 1 3 are connected with a flat washer 19 for the pin shaft. In addition, a pin shaft B type 12 is installed on the surface of the flip box body 1, and one end of the pin shaft B type 12 passes through the flip box body 1 and is connected with a flat washer 20 for the pin shaft.

[0026] A hexagonal thin nut with fine teeth 13 is provided at the lower end of the cylinder front stopper 5, and a hexagonal screw with a hole bolt 15 is installed on the surface of the flip hinge ear 7. The hexagonal screw with a hole bolt 15 is connected to the flip hinge ear 7 through a type-2 hexagonal slotted nut 14, and a cotter pin 21 is provided at the end of the type-2 hexagonal slotted nut 14.

[0027] The inner side of the lifting ring fixing bent plate 2 is connected with a nylon block 16 via a hexagonal cone-end set screw 17 .

[0028] It should be noted that the main mechanism 23 is mainly composed of a side door, a side door connecting rod, a side door transmission shaft, a hinged joint, an elevator switch cylinder, a dustproof rubber retaining ring, an elevator, a lock tongue connecting rod, a lock tongue transmission member and a lock tongue, and the surface of the main mechanism 23 is provided with bushings of different specifications;

[0029] The buckle mechanism 26 is mainly composed of a buckle box, a sucker rod guide bushing, an adjusting bolt, a lower guide rubber, an adjusting mounting frame, a collar, a buffer pad, an upper guide rubber, a connecting strip, a protective shell and a splashproof buckle cap;

[0030] The buckle-making and buckling mechanism 27 is mainly composed of a slide rail, a bracket, power tongs teeth, a cylinder and a bottom plate;

[0031] The suspension mechanism 25 is mainly composed of a connecting member, a suspension shaft and a suspension frame. The above mechanisms are already public prior art and will not be described one by one here.

[0032] The upper end of the flipping mechanism 28 is connected to the hook of the side swing mechanism 29 , and the lower end of the flipping mechanism 28 is connected to the main machine mechanism 23 .

[0033] Working principle: When the sucker rod hanger is stuck in the lower sucker rod, the flip mechanism 28 flips to the take-over state, and the flip mechanism 28 is moved to the oil outlet through the side swing mechanism 29, so as to facilitate the upper and lower sucker rod operations. When the flip mechanism 28 moves to the appropriate position, the flip hydraulic cylinder 9 and the flip hinge ear 7 and the flip seat 4 cooperate with each other, so as to achieve the effect of flipping the main mechanism 23;

[0034] When the sucker rod lowering process is in progress, the lifting card of the side swing mechanism 29 falls and turns over to the specified position, the pipe laying machine 22 pushes the sucker rod into the interior of the lifting card, the flange position is above the bushing, the lifting card is slowly lifted up, the sucker rod enters the lifting card visually, the side door lock tongue is closed, and the lifting card is continued to be lifted up. The sucker rod slides downward in the elevator bushing due to gravity until the flange position enters the bushing groove. At the same time, the pipe laying machine 22 cooperates to convey the sucker rod forward, and the lower end of the sucker rod moves to the front end of the pipe laying machine 22. The manipulator rotates to the front end position of the pipe laying machine 22, the manipulator claws embrace the sucker rod, the lifting card moves up, and the sucker rod is lifted. At the same time, the manipulator rotates to the center of the wellhead, the lifting card falls, and the sucker rod moves down (the buckle mechanism 26 is synchronously pushed forward to the center of the wellhead and closed), and the lower end of the sucker rod falls to 20 cm above the buckle device The lowering speed is slowed down at this time, and the elevator slowly falls. The lower end of the sucker rod enters the buckle mechanism 26 and continues to fall until the external thread of the sucker rod enters the inner hole of the coupling. The buckle device is opened, and the hydraulic clamp moves to the well control center position. The main clamp and the backup clamp of the hydraulic clamp work, and the clamp teeth extend and clamp the four positions of the upper and lower sucker rods respectively. The hydraulic clamp reverses to buckle up, and then rotates forward to buckle up (the manipulator is still in the center of the wellhead to have a straightening effect). The buckle up is completed, and then the hydraulic clamp returns to its original position, the manipulator is opened, the elevator is lifted for a distance (about 200mm), the slip is opened, and the elevator falls to about 500mm from the upper end of the slip at the bottom of the elevator. The slip is closed, and the elevator continues to fall to the upper end surface of the slip. The elevator is opened, and the side swing mechanism 29 works to make the elevator clear the center of the wellhead. The elevator is lifted to the next process and the process is repeated;

[0035] When the sucker rod lifting process is in progress, the elevator falls to about 500mm above the slip, the side swing mechanism 29 works, the elevator leaves the wellhead position, the side door lock tongue opens, the elevator continues to fall, and when the elevator bushing is below the sucker rod flange position, the side swing mechanism 29 works, the elevator returns to the wellhead center position, the elevator side door and lock tongue close, and the elevator is lifted for a distance until the bottom end of the elevator leaves the upper end of the slip, the slip is opened, and the elevator continues to lift until the flange of the second sucker rod is about 200mm above the upper end of the slip, the slip is closed, the elevator falls so that the sucker rod flange falls into the slip groove, and the hydraulic clamp Move to the center of the wellhead, and at the same time, the manipulator moves to the center of the wellhead and embraces the sucker rod, the hydraulic clamp teeth extend to clamp the upper and lower sucker rods at the four positions respectively, and the hydraulic clamp shackles. After the shackles are shattered, the hydraulic clamp teeth open, and the hydraulic clamp retreats to the initial position. The elevator is lifted and the manipulator rotates to put the sucker rod into the pipe laying car (the pipe laying car is in place in advance), the pipe laying car is closed, and the sucker rod is pressed down. The pipe laying car moves backward and the elevator falls. After the sucker rod completely falls on the pipe laying machine 22, the elevator opens and continues to fall for a distance, the trolley continues to move backward, and the sucker rod is separated from the elevator, and the process is repeated.
