[0003] The existing end bending detection is carried out by a micrometer, which measures the total runout on the processed shoulder outer diameter of the external threaded joint with a micrometer, and screens out the sucker rods with abnormal tolerance according to the measurement results for straightening. The sucker rods need to be transferred to the inspection site after tempering treatment and inspected one by one. The measurement process is complicated and inefficient, and it is impossible to screen out the sucker rods with abnormal tolerance in time after tempering treatment, which also affects the sucker rods with normal tolerance from entering the next process.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical scheme and advantages of the embodiments of the present application clearer, the technical scheme in the embodiments of the present application is clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work also fall within the scope of protection of the present application.

[0023] like Figure 1-Figure 6 As shown, an embodiment of the present application provides a bending detection device for the rear end of a sucker rod after tempering treatment, comprising a detection table 1, one end of the detection table 1 is connected to the discharge end of a cooling bed 2, and the other end is provided with a first material basket 4, the table top of the detection table 1 is inclined downward in the direction of the first material basket 4, and is used to make the sucker rod 15 rotate along the table top and roll into the first material basket 4, and detection mechanisms 3 are provided on both sides of the detection table 1 along the rolling direction of the sucker rod 15, and the detection mechanism 3 is C-shaped with an opening at one end, and the upper and lower plates forming the C-shape of the detection mechanism 3 are horizontal straight plates and are arranged in parallel, and the spacing between the upper and lower plates is the tolerance of the maximum bending degree of the sucker rod 15, and the openings of the detection mechanism 3 on both sides are arranged relatively to each other, and the C-shaped opening of the detection mechanism 3 can accommodate the two ends of the sucker rod 15 that do not exceed the tolerance to pass through.

[0024] When in use, the sucker rod 15 cooled by the cooling bed 2 falls horizontally from the discharge end to one end of the connection of the inspection table 1, and the sucker rod 15 rolls from the high place to the low place on the top surface of the inspection table 1. During the rolling process, the two ends of the sucker rod 15 pass through the C-shaped opening of the inspection mechanism 3 horizontally. The two ends of the sucker rod 15 that are within the tolerance can rotate around the central axis, pass through the C-shaped opening of the inspection mechanism 3 smoothly, and fall into the first material basket 4 from the other end of the inspection table 1. If the sucker rod 15 has an end with a bending degree that exceeds the tolerance, its end will swing up and down in a circular shape during the rolling process along the top surface of the inspection table 1, and cannot rotate around the central axis. The bent end is stuck when passing through the C-shaped opening of the inspection mechanism 3 and cannot pass smoothly. After staying at the inspection mechanism 3, the inspection personnel will take it away and straighten it in time.

[0025] In this embodiment, after the sucker rod 15 after tempering is removed from the cooling bed 2, the two ends are subjected to bending inspection by the inspection mechanism 3 during the process of rolling down along the inspection table 1 to the first material basket 4. The two ends of the sucker rod 15 extend out of the side of the inspection table 1. During the horizontal rolling process on the inspection table 1, the two ends that are within tolerance can enter from one side of the C-shaped opening of the inspection mechanism 3 and pass through the other side, fall into the first material basket 4 and enter the next process. The ends of the sucker rod 15 that are out of tolerance are bent and cannot pass through the C-shaped opening of the inspection mechanism 3 smoothly. After being screened out, the inspection personnel take them away for straightening.

[0026] In a possible implementation, the detection mechanism 3 is composed of a vertical plate 6 and two upper and lower limit plates 7 fixed parallel to each other. The detection mechanism 3 is fixed to the side end of the detection platform 1 through a support frame 5 connected to the vertical plate 6.

[0027] The two limit plates 7 and the vertical plate 6 together form a C-shaped detection mechanism 3, and are fixed to the ground through a support frame 5. The detection mechanism 3 can be flexibly set to adapt to bending detection of sucker rods 15 of different specifications.

[0028] In a possible implementation, fixed plates 8 are respectively fixed at the upper and lower ends of the vertical plate 6, and the two limit plates 7 are located between the two fixed plates 8 and are slidably connected to the vertical plate 6. A threaded rod 9 with a threaded connection passes through the fixed plate 8, and the end of the threaded rod 9 is rotationally connected to the limit plate 7.

[0029] The limit plate 7 slidably connected to the vertical plate 6 can adjust the height position and spacing through the threaded rod 9. The threaded rod 9 passing through the fixed plate 8 is rotatably connected to the limit plate 7 at the corresponding position. Rotating the threaded rod 9 can push the limit plate 7 up and down to achieve the purpose of flexible adjustment.

[0030] In a possible implementation, a material receiving table 10 is provided between the detection table 1 and the cooling bed 2, and the material receiving table 10 is hinged to one side of the horizontal plate 11, and the other side of the horizontal plate 11 can be fitted and spliced ​​with the detection table 1, and the material receiving table 10 and the horizontal plate 11 have the same slope as the detection table 1 and are in the same plane, and a semicircular telescopic rod 12 is installed at the bottom of the horizontal plate 11 and the material receiving table 10, and a spring capable of lifting the horizontal plate 11 is provided in the semicircular telescopic rod 12, and the detection mechanism 3 is located on one side of the cooling bed 2 and aligned with the joint of the horizontal plate 11 and the detection table 1.

[0031] The sucker rods 15 that are out of tolerance cannot continue to roll through the detection mechanism 3 and stay at the upper end of the horizontal plate 11. The semicircular telescopic rod 12 is retracted by pressing the horizontal plate 11 downward, and the horizontal plate 11 is rotated and folded downward along the hinge of the material receiving table 10, and the side that is spliced ​​with the detection table 1 is opened downward, so that the sucker rods 15 that are out of tolerance are separated and screened out in time to avoid affecting the subsequent sucker rods 15 to be detected. After loosening the horizontal plate 11, the semicircular telescopic rod 12 is extended by the spring in the semicircular telescopic rod 12, and the horizontal plate 11 is lifted to the same plane as the material receiving table 10.

[0032] In a possible implementation, handles 13 for rotating and pressing the horizontal plate 11 are fixed at both ends of the horizontal plate 11 .

[0033] Holding the handle 13 facilitates operating the horizontal plate 11 to press down and separate the sucker rod 15 that is out of tolerance.

[0034] In a possible implementation, a second material basket 14 is provided below the transverse plate 11 .

[0035] The out-of-tolerance sucker rods 15 are separated by pressing down the transverse plate 11 and can fall downward into the second material basket 14 for centralized straightening.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, ordinary technicians in the field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
