Due to the importance of its operation, the straightness of the sucker rod needs to meet certain requirements. Therefore, after the heat treatment process of the sucker rod, the sucker rod needs to be stretched and straightened.

[0003] After searching, a Chinese patent discloses an automatic sucker rod straightening device, and its authorization announcement number is (CN218963680U), which includes a calibration table, two brackets are fixedly connected to the center of the top of the calibration table, and the tops of the two brackets are fixedly connected to positioning frames, and the two positioning frames are commonly provided with positioning rings inside, and the tops of the positioning frames are fixedly connected to a driving motor, and the driving shaft of the driving motor is fixedly connected to a driving wheel.

[0004] This patented technology drives the pump rod to rotate through a driving motor, which is convenient for manual observation of straightness, and heats the pump rod through a stove, and then straightens it by manual knocking. Considering that the pump rod itself has a certain strength, it needs to be straightened repeatedly when it is manually knocked with an aluminum hammer, which easily increases the labor intensity of the staff and has a certain error. To address the above problems, we have launched an automatic pump rod straightening device. Utility Model Content

Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application usually described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0023] Example 1

[0024] Reference Figures 1 to 4 A sucker rod automatic straightening device comprises a calibration seat 1, a translation table 2 is arranged between the two sides of the calibration seat 1, a transverse plate 11 is fixedly connected between the inner sides of the translation table 2, both ends of the top of the transverse plate 11 are fixedly connected with a second U-shaped plate 12, the second U-shaped plate 12 is internally rotatably connected with a bearing roller 13, an electric telescopic rod 3 is fixedly installed on the top of the translation table 2, the bottom end of the movable rod of the electric telescopic rod 3 is fixedly connected with a first U-shaped plate 4, the first U-shaped plate 4 is internally rotatably connected with a straightening roller 5, both ends of the top of the calibration seat 1 are fixedly connected with an H-shaped plate 7, the inner sides of the H-shaped plate 7 are rotatably connected with a supporting roller 8, gas pipes 17 are installed on both sides of the translation table 2, a stove is arranged at one end of the gas pipe 17, and a displacement component for driving the translation table 2 to move is arranged at the bottom of the transverse plate 11.

[0025] In the above technical solution, the oil push pipe is placed on two support rollers 8 and a bearing roller 13, as shown in FIG. Figure 4As shown in the dotted line part, by manually rotating the oil push rod and observing the straightness, it is found that the bent part can directly move the oil push rod on the support roller 8 so that the bent part is between the two support rollers 8, and then the displacement component is used to drive the straightening roller 5 to move above the bent part. Then the gas pipe 17 is connected to natural gas or liquefied gas to heat the bent part, and then the electric telescopic rod 3 is used to drive the straightening roller 5 to move downward. In this way, with the bearing roller 13 as two support points, the straightening roller 5 applies pressure to the bent part, thereby achieving the purpose of straightening, avoiding repeated manual knocking, improving the straightening accuracy, and making it more conducive to practical use.

[0026] Example 2

[0027] Reference Figure 1 and Figure 3 The displacement assembly includes a servo motor 15, which is fixedly mounted on the top of the horizontal plate 11. The output shaft of the servo motor 15 extends to the bottom of the horizontal plate 11 and is fixedly connected with a gear 16. The top of the calibration seat 1 is fixedly connected with a fixed rack 14, and the gear 16 is meshed with the fixed rack 14. By setting the displacement assembly, considering that the distance between the two support rollers 8 is constant and the length of the oil push rod is long, when the oil push rod is moved, the bending part can be controlled between the two support rollers 8, and then the gear 16 is driven to rotate by the servo motor 15. Since the gear 16 is meshed with the fixed rack 14, the translation table 2 is driven to move, so that the straightening roller 5 is moved to the bottom of the bending part. In this way, it can be applied to oil push rods of different lengths and avoids frequent movement of the oil push rod.

[0028] Reference Figure 2 , both sides of the calibration seat 1 are provided with strip grooves 9, and rollers 10 are rotatably connected to the inner side of the translation platform 2 and located inside the strip grooves 9, and the outer surface of the roller 10 abuts against the top of the inner wall of the strip groove 9. Through the rollers 10 and the strip grooves 9 that cooperate with each other, the outer surface of the roller 10 abuts against the top of the inner wall of the strip groove 9, so that the translation platform 2 can reduce friction when moving, and at the same time, the translation platform 2 has a protruding plate, so that the calibration seat 1 can be clamped with the rollers 10, so that it can slide outside the calibration seat 1.

[0029] Reference Figure 3 The cross section of the roller 10 is a concave structure with high sides and low middle. The structure of the roller 10 concave in the middle makes the roller 10 not move to the sides when rolling inside the strip groove 9, thereby preventing the translation platform 2 from deflecting.

[0030] Reference Figure 2The top of the translation table 2 and both sides of the electric telescopic rod 3 are slidably connected with guide rods 6, and the bottom ends of the guide rods 6 are fixedly connected to the first U-shaped plate 4. When the electric telescopic rod 3 drives the straightening roller 5 to move up and down, the guide rods 6 are driven to slide inside the translation table 2, so that the straightening roller 5 is restricted in the vertical direction by the guide rods 6 to move up and down.

[0031] Reference Figure 4 , the vertices of the outer surfaces of the support roller 8 and the bearing roller 13 are at the same height. By setting the same height, it can be ensured that when the oil push rod is placed, the two bearing rollers 13 can abut against the oil push rod, so that after the straightening roller 5 moves down, the two bearing rollers 13 can serve as support points to ensure that no displacement occurs in the vertical direction.

[0032] Reference Figure 1 The outside of the straightening roller 5, the support roller 8 and the bearing roller 13 are all covered with high temperature resistant rubber rings. By setting the rubber ring on the outside, considering that after the oil push rod is heated by the gas pipe 17, its surface still has a relatively high residual temperature, so the high temperature resistant rubber ring is used, and the rubber ring can play a buffering role.

[0033] Working principle: When straightening the oil push rod, first place the oil push pipe on two support rollers 8 and the bearing roller 13, rotate the oil push rod manually and observe the straightness, then move the oil push rod so that the bending part is between the two support rollers 8. Then the servo motor 15 drives the gear 16 to rotate. Since the gear 16 is meshed with the fixed rack 14, it drives the translation table 2 to move, so that the straightening roller 5 moves to the bottom of the bending part. Connect the gas pipe 17 to natural gas or liquefied gas to heat the bending part. Finally, use the electric telescopic rod 3 to drive the straightening roller 5 to move downward, so that the bearing roller 13 is used as two support points, and the straightening roller 5 applies pressure to the bending part to achieve the straightening purpose.

[0034] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this. The replacement can be a replacement of part of the structure, device, method step, or a complete technical solution. Equivalent replacement or change based on the technical solution of the utility model and its utility model concept should be included in the protection scope of the utility model.
