Description

Technical Field

[0001] The utility model relates to the technical field of sucker rod rolling repair devices, in particular to a high-strength sucker rod rolling repair device. Background Technique

[0002] A sucker rod is a slender rod of a pumping well. It is connected to a polished rod at the upper end and a sucker pump at the lower end to transmit power. When in use, the sucker rod will be damaged to a certain extent, and usually a rolling repair device is needed to repair the sucker rod.

[0003] For example, a high-strength sucker rod rolling repair device with the publication number of "CN217194313U". When in use, by rotating the rotating handle, the rotating handle will drive the second belt to rotate. There is a third pulley connected between the two second belts. Therefore, the two second belts will rotate simultaneously, so that the slider will rotate simultaneously. The slider will drive the fixed rod to move towards each other. The clamping plates at one end of the two fixed rods will clamp the sucker rod. There are balls inside the clamping plate to prevent the sucker rod from shaking during repair. However, for this high-strength sucker rod rolling repair device, the grinding roller is controlled to lift by the hydraulic expansion rods on both sides. Starting and stopping easily causes the hydraulic expansion rods on both sides to be out of sync, resulting in inaccurate positions of the grinding roller, and thus the subsequent repaired sucker rods are unqualified. At the same time, for this high-strength sucker rod rolling repair device, the operator needs to rotate the rotating handle to fix the sucker rod. When there are many sucker rods to be repaired, it will consume a lot of physical strength of the operator, thus increasing the labor force. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problems that when the grinding roller is lifted and lowered by the hydraulic expansion rods on both sides, starting and stopping easily causes the hydraulic expansion rods on both sides to be out of sync, resulting in inaccurate positions of the grinding roller, and thus the subsequent repaired sucker rods are unqualified. At the same time, for this high-strength sucker rod rolling repair device, the operator needs to rotate the rotating handle to fix the sucker rod. When there are many sucker rods to be repaired, it will consume a lot of physical strength of the operator, thus increasing the labor force, and to propose a high-strength sucker rod rolling repair device.

The end of the lower second air cylinder is fixedly connected with the left first box body, and the end of the upper second air cylinder is fixedly connected with a fourth bent plate.

[0009] Preferably, the fourth bent plate is fixedly connected with the first bent plate. The inner wall of the third bent plate is rotatably connected with two second grinding rollers through bearings.

[0010] Preferably, the limiting mechanism includes a first air cylinder and a bent rod. The output end of the first air cylinder is fixedly connected with a slider.

[0025] Refer to the appendix Figures 2-3 and the appendix Figure 5

[0026] The limiting mechanism 5 includes a first cylinder 501 and a bent rod 504. The output end of the first cylinder 501 is fixedly connected with a slider 502.

The movement of the lower second rollers 505 drives the bent rod 504 to move synchronously.

[0027] Working principle:

[0028] When using the rolling repair device to repair high-strength sucker rods:

[0029] Preparation process:

[0030] The operator places the high-strength sucker rod to be repaired between the two bent rods 504, starts the first cylinder 501. The extension of the output end of the first cylinder 501 drives the slider 502 to move, thereby driving the lower second rollers 505 to move, and at the same time driving the first roller 503 to move. The movement of the lower second rollers 505 drives the lower ends of the bent rod 504 to move outward synchronously, causing the upper ends of the bent rod 504 to move inward. When the outer walls of the high-strength sucker rod to be repaired are in close contact with the first roller 503 and the two second rollers 505 respectively, the first cylinder 501 is turned off. When fixing the high-strength sucker rod to be repaired, it does not require the operator to consume a lot of physical strength to turn the crank, thus saving labor.

[0031] Adjustment process:

[0032] First, for the second cylinder 401 below, the output end of the second cylinder 401 extends to drive the slide plate 402 to slide along the outer wall of the fixed column 404. The movement of the slide plate 402 drives the first cylinder 403 to slide along the inclined groove machined on the slide plate 402. The movement of the first cylinder 403 drives the vertical rod 405 to move upward. The upward movement of the vertical rod 405 drives the third bent plate 13 to move, thereby driving the second grinding roller 12 to move upward. When the outer walls of the second grinding rollers 12 are all in close contact with the surface of the high-strength sucker rod to be repaired, turn off the second cylinder 402 below, and then start the second cylinder 401 above to drive the vertical rod 402 to move downward, thereby driving the second bent plate 11 to move downward. When the first grinding roller 10 is in close contact with the surface of the high-strength sucker rod to be repaired, turn off the second cylinder 401 above, and then start the power supply of the motor 7. The rotation of the output shaft of the motor 7 drives the first grinding roller 10 to rotate, thereby driving the high-strength sucker rod to be repaired to rotate, and at the same time driving the two second grinding rollers 12 to rotate to repair the high-strength sucker rod to be repaired. The repair method is the same as that of the sucker rod repair method in the publication number "CN217194313U". By using the same driving force to make the two move synchronously up or down, the synchronism of the two sides of the structure is better, avoiding the situation that the start and stop are out of sync when using cylinders on both sides, which affects the position of the grinding roller and reducing the probability of the subsequent repaired sucker rod being unqualified. When the high-strength sucker rod to be repaired is repaired, turn off the power supply of the motor 7, start the first cylinder 9 and the second cylinder 402 to reset the first grinding roller 10 and the second grinding roller 12, and then start the two first cylinders 501. Using the elastic force of the tension spring 507, reset the upper ends of the two bent rods 504, and then the operator removes the repaired high-strength sucker rod.
