[0021] In the following description, numerous details are explored to provide a more thorough explanation of embodiments of the present invention.

[0022] Please see Figure 1 This utility model provides a detection device for oil pipe mounting holes, including a mounting frame 1 and a detection component 2. The mounting frame 1 is provided with a detection part 11 and a fixing part 12 for installation. The mounting frame 1 is connected to the oil pipe through the fixing part 12. The detection part 11 is located above the mounting frame 1, and the fixing part 12 is located below the mounting frame 1. The detection component 2 includes a mounting part 21, a positioning part 22, and a detection element 23. The mounting part 21 is detachably connected to the mounting frame 1, and both the detection element 23 and the positioning part 22 are connected to the mounting part 21. During detection, the positioning part 22 extends into the oil pipe mounting hole, thereby causing the detection element 23 to contact the detection part 11. When the positioning part 22 extends to the bottom of the oil pipe mounting hole, the detection element 23 is in complete contact with the detection part 11, and the detection element 23 exhibits a detection structure. The positioning part 22 has a detection position and a disengagement position. When the detection element 23 separates from the detection part 11, the positioning part 22 is in the disengagement position; when the detection element 23 comes into contact with the detection part 11, the positioning part 22 is in the detection position.

[0023] In this embodiment, the positioning part 22 is a cylindrical structure, and the diameter of the end of the positioning part 22 away from the mounting part 21 is reduced, so that a limiting step is formed on the positioning part 22. When the positioning part 22 extends into the oil pipe mounting hole, the limiting step has the effect of limiting the position. The diameter of the limiting step of the positioning part 22 is larger than the diameter of the oil pipe mounting hole. After the end of the positioning part 22 away from the mounting part 21 extends into the oil pipe mounting hole, it stops moving after the limiting step contacts the oil pipe mounting hole.

[0024] Specifically, in one optional embodiment of this application, the mounting bracket 1 is provided with a mounting hole 13, which is a round hole. The detection part 11 is a cylindrical structure and is detachably disposed in the mounting hole 13. The upper part of the detection part 11 protrudes from the mounting hole 13. The side wall of the mounting bracket 1 is provided with a locking hole, which communicates with the mounting hole 13. A locking member 14 for fixing the detection part 11 is provided in the locking hole. The locking member 14 fixes the detection part 11 by pressing against it. Alternatively, a round hole is provided at the lower part of the detection part 11, and one end of the locking member 14 passes through the locking hole and is disposed in the round hole to fix the detection part 11.

[0025] Specifically, in one optional embodiment of this application, the mounting bracket 1 is provided with a mounting groove 15, the mounting groove 15 being along the width direction of the mounting bracket 1. Figure 1 The detection unit 11 is slidably positioned in the mounting groove 15 (vertical direction) to facilitate adjustment of the front and rear distance of the detection unit 11, thereby adjusting the initial distance between the detection unit 11 and the detection piece 23, which can adapt to the detection requirements of different types of oil pipes.

[0026] Please see Figure 3 Specifically, in an optional embodiment of this application, sliding grooves 16 are provided on both inner walls of the mounting groove 15, and sliding parts 17 are provided on both opposite sides of the detection part 11. The two sliding parts 17 are slidably disposed in the sliding grooves 16. When the detection part 11 slides in the mounting groove 15, the sliding grooves 16 and the sliding parts 17 can play a longitudinal limiting role for the detection part 11.

[0027] In this embodiment, the sliding part 17 is an annular structure, and the sliding part 17 protrudes from the detection part 11 and is disposed in the sliding groove 16.

[0028] Specifically, in one optional embodiment of this application, the mounting groove 15 penetrates the mounting bracket 1. The detection unit 11 has a fixing groove 18 arranged from top to bottom. The fixing groove 18 has a circular cross-section and a fixing rod 19 is provided within it. The fixing groove 18 has an internal thread, and the fixing rod 19 has an external thread, with the fixing rod 19 threadedly engaging with the fixing groove 18. The top of the fixing rod 19 extends out of the fixing groove 18 and has a rotating handle. The bottom of the fixing rod 19 extends out of the fixing groove 18, and a locking disc 110 is located at the bottom of the fixing rod 19, below the mounting bracket 1. The locking disc 110 has a locked state and a released state. When the locking disc 110 abuts against the mounting bracket 1, it is in the locked state; when the locking disc 110 separates from the mounting bracket 1, it is in the released state. When it is necessary to fix the detection unit 11, rotate the adjusting handle to raise the locking plate 110 until it abuts and locks against the mounting bracket 1. When it is necessary to move the detection unit 11, rotate the adjusting handle in the opposite direction to lower the locking plate 110, thereby separating the locking plate 110 from the mounting bracket 1. This achieves both fixing and adjusting of the detection unit 11, preventing displacement of the detection unit 11 when it contacts the detection piece 23, which could lead to inaccurate detection.

[0029] Specifically, in an optional embodiment of this application, the detection device further includes a calibration component 3 for calibrating the detection element. The calibration component 3 facilitates the correction of the detection element 23 and reduces the error that may occur during detection.

[0030] Please see Figure 2Specifically, in an optional embodiment of this application, the calibration component 3 includes a calibration base 31, a calibration ring 32, and a calibration rod 33. The calibration base 31 is detachably mounted on the mounting bracket 1. The calibration ring 32 and the calibration rod 33 are both mounted on the calibration base 31 and are arranged adjacent to each other. The calibration ring 32 has a calibration groove for accommodating the positioning part 22. When the positioning part 22 is located in the calibration groove, the calibration rod 33 abuts against the detection element 23. When the detection element 23 needs calibration, the positioning part 22 is placed in the calibration groove. When the bottom of the positioning part 22 abuts against the calibration base 31, the calibration rod 33 abuts against the detection element 23, at which point the reading of the detection element 23 returns to zero.

[0031] In this embodiment, the detection component 23 is a dial indicator. The reading changes when the telescopic part is subjected to force, resulting in small detection data error and convenient operation.

[0032] Specifically, in one optional embodiment of this application, the end of the mounting part 21 away from the positioning part 22 has two clamping parts 24 protruding out, and a clamping gap is formed between the two clamping parts 24. The detection element 23 is disposed in the clamping gap.

[0033] Specifically, in one optional embodiment of this application, adjustment holes are provided on the opposite surfaces of the two clamping parts 24. The adjustment holes penetrate the clamping parts 24 and a locking screw 25 is inserted into the adjustment holes. By adjusting the locking screw 25, the width of the clamping gap between the two clamping parts 24 is adjusted, thereby adjusting the installation position of the detection piece 23 to accommodate more oil pipe sizes.

[0034] Specifically, in one optional embodiment of this application, the mounting frame 1 is a long strip structure, and multiple detection units 11 are provided. The multiple detection units 11 are arranged along the length direction of the mounting frame 1, and the multiple detection units 11 can simultaneously detect multiple oil pipe mounting holes.

[0035] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
