Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of laser measurement, in particular to a laser detection device capable of continuously measuring the wall thickness of a pipe. BACKGROUND

[0002] As the core component of fluid transportation and structural support, the market demand of pipes is showing a rapid growth trend, and the application field has expanded from traditional oil and gas transportation, municipal water supply and drainage to deep sea engineering, new energy and aerospace high-end scenes. Wall thickness, as a key parameter directly affecting the pressure bearing capacity, fatigue resistance and service life of pipes, the precision control is of decisive significance to ensure engineering safety. Therefore, comprehensive and accurate wall thickness detection before pipe delivery has become an industry mandatory standard. The traditional detection method relies on manual holding of measuring tools for sampling detection, and the data is obtained by manually reading discrete measuring points selected on the circumference of the pipe. This method not only has low detection efficiency and is difficult to match the continuous output speed of modern production lines, but also has insufficient data representation, and the random selection of points may miss local defects. At the same time, the difference in the operation method and reading of the operator will cause significant human error, which cannot meet the quality control requirements of high-precision pipes. Nowadays, the industry gradually adopts laser scanning imaging technology to realize automatic detection. By deploying a rotating laser sensor to scan around the outer wall of the pipe, the wall thickness value is obtained. Although this method has improved the detection efficiency, due to the possible ovality deviation or port cutting inclination of the pipe after extrusion molding, the existing equipment needs to manually calibrate the coaxiality of the laser sensor and the center of the pipe. The switching time for different pipe diameters is relatively long, which directly restricts the changeover efficiency of the continuous production line. At the same time, due to the influence of cutting, the pipe port itself will be attached with a large amount of debris and particulate attachments, which will directly affect the data accuracy during laser scanning. Therefore, the existing pipe wall thickness laser detection device still has deficiencies in dealing with continuous detection, and actual use still needs to be improved. SUMMARY

The advancing and retreating rotating measuring component comprises a motor 14, the output end of the motor 14 is fixedly connected with a driving shaft 15, the end of the driving shaft 15 is fixedly connected with a rotating drum 16, the side wall of the rotating drum 16 is provided with a moving groove 17, the moving groove 17 comprises two arc-shaped grooves and a circumferential groove, the surface of the rotating drum 16 at the circumferential groove is fixedly connected with an arc-shaped rack 18, the inner wall of the moving groove 17 is slidably connected with a transmission shaft 19, the shaft wall of the transmission shaft 19 is fixedly connected with a mounting sleeve two 20, the inner wall of the mounting sleeve two 20 is slidably connected with the surface of the shaft body one 11, and the surface of the mounting sleeve two 20 is rotatably connected with the end of the shaft body two 12.

[0021] More specifically, in this embodiment: after the pipe is in place, the position of the laser measuring plate 3 and the brush plate 4 is automatically adjusted through the central shaft adapting component, then the motor 14 is started to start the wall thickness data collection process, when the motor 14 is started, the driving shaft 15 is driven to rotate, thereby driving the rotating drum 16 to rotate through the transmission of the driving shaft 15, at this time, the moving groove 17 is simultaneously driven to move, in this process, the transmission shaft 19 will slide along the inner wall of the moving groove 17, that is, the transmission shaft 19 will move away from the motor 14, until the transmission shaft 19 moves from the arc-shaped groove to the circumferential groove, in this process, the mounting sleeve two 20 is driven to move through the transmission shaft 19, thereby driving the shaft body two 12 to move through the mounting sleeve two 20, and then the laser measuring plate 3 is driven to displace towards the brush plate 4 through the positioning mounting block 13; The advancing and retreating rotating measuring component further comprises a gear 21, the gear 21 is fixedly connected to the surface of the shaft body two 12 and is engaged with the teeth of the limiting sliding seat 9, the limiting sliding seat 9 is provided with a notch, the position of the notch corresponds to the arc-shaped rack 18, the surface of the shaft body one 11 is provided with a deflection groove 22, and the inner wall of the shaft body two 12 is fixedly connected with a plug rod 23 inserted into the deflection groove 22; It is worth noting that in the process of moving the laser measuring plate 3 to the direction close to the brush plate 4, the plug rod 23 will slide along the inner wall of the deflection groove 22, and at the same time, since the gear 21 is kept in meshing constraint relationship with the limiting sliding seat 9, the shaft body two 12 will not be able to rotate, so as to drive the shaft body one 11 to deflect first, that is, in the process of moving the laser measuring plate 3 to the direction close to the brush plate 4, the brush plate 4 is deflected in advance. With the continuous rotation of the motor 14, the transmission shaft 19 will slide along the groove wall of the circumferential groove, and in this process, the gear 21 meshes with the arc-shaped rack 18, and at the same time, the gear 21 is located at the gap, so in this process, the shaft body two 12 will be rotated, and since the shaft body one 11 cannot produce axial movement, in the process of rotating the shaft body two 12, the shaft body one 11 will be driven to rotate synchronously through the deflection groove 22, and through the cooperation of the arc-shaped rack 18 and the gear 21, the gear 21 will rotate one circle, at this time, the laser measuring plate 3 completes a rotation process, and the pipe port wall thickness data are all collected, then the transmission shaft 19 slides along the arc-shaped groove again to drive the device to reset, so as to make the brush plate 4 reset inversely, and at the same time, the laser measuring plate 3 moves away from the brush plate 4. Through the above-mentioned mode, first of all, through the setting of the brush plate 4, one circle of cleaning work can be carried out on the pipe port, and the debris and attachments generated due to cutting are removed, so as to facilitate the accuracy of subsequent data collection of the laser measuring plate 3, and at the same time, it can be known from the above process that the brush plate 4 has the characteristic of moving in advance, which can first ensure that the pipe port region moved by the laser measuring plate 3 for one circle is in a cleaned state, and the brush plate 4 can keep a certain distance from the laser measuring plate 3, and the two will not interfere with each other, and in the process of rotating the laser measuring plate 3 to collect data, the situation that the laser data recording is disturbed due to the close distance between the two and the debris falling off will not occur, and at the same time, it can be known from the above that the laser measuring plate 3 is relatively far away from the port position of the pipe during non-detection, and only when the detection starts can it be close to the position, and this can also ensure that the pipe will not contact the laser measuring plate 3 during feeding and discharging, so as to avoid the damage of the instrument due to accidental contact and other factors.

[0022] In the above embodiment, on the basis of the above embodiment: Please refer to Figures 1 to 3The middle shaft adaptive component comprises: a positioning moving rod 24 fixedly connected with the inner wall of the mechanical clamp rod 2, a self-adaptive plate 25 fixedly connected with the bottom surface of the mounting plate group 6, a self-adaptive groove 26 formed in the surface of the self-adaptive plate 25, wherein the self-adaptive groove 26 comprises a horizontal groove and an inclined groove, a rod wall of the positioning moving rod 24 is in sliding connection with the inner wall of the self-adaptive groove 26, a double-head motor 27 is fixedly connected with the bottom surface of the measuring frame 1, two output ends of the double-head motor 27 are both fixedly connected with threaded rods 36, the end portions of the two threaded rods 36 are both in rotational connection with the inner wall of the measuring frame 1, the rod walls of the two threaded rods 36 are both in threaded connection with threaded blocks 37, and the surfaces of the two threaded blocks 37 are both fixedly connected with the end portions of the two positioning moving rods 24.

[0023] More specifically, in the embodiment: after the pipe material is loaded in place, the double-head motor 27 can be started to drive the threaded blocks 37 to move through the rotation of the threaded rods 36, at this time, the two groups of mechanical clamp rods 2 can be driven to relatively displace through the transmission of the positioning moving rod 24, so as to clamp the pipe material and keep the stability of the pipe material during measurement, and in the process of moving of the positioning moving rod 24, the positioning moving rod 24 will also slide along the groove wall of the self-adaptive groove 26, when the size of the pipe material is small, the positioning moving rod 24 will slide along the inclined groove on the self-adaptive groove 26, which drives the mounting plate group 6 to move downward through the self-adaptive plate 25, and then drives the laser measuring plate 3 and the brush plate 4 to synchronously move downward through the transmission of the mounting plate group 6, since the inclined groove is formed in a 45° state, the moving distance of the mechanical clamp rod 2 is consistent with the moving distance of the mounting plate group 6, which can make the deflection centers of the laser measuring plate 3 and the brush plate 4 always located at the middle axis position of the pipe material, and can be self-adaptive without manual adjustment, which is more friendly to the continuous measurement process.

[0024] Embodiment three, based on the above-mentioned embodiments: Please refer to Figures 4 to 7 The reset and cleaning component comprises: a magnetic cylinder 28 in rotational connection with the inner wall of the mechanical shell 8 and constrained in the rotating state by a magnet, a plurality of arc-shaped plates 29 fixedly connected with the inner wall of the magnetic cylinder 28, a group of impact rods 30 in sliding connection with the inner wall of the mechanical shell 8, the surfaces of the group of impact rods 30 being connected with the inner wall of the mechanical shell 8 through impact springs 31, a pin shaft 32 fixedly connected with the side wall of the group of impact rods 30, an end portion of a ratchet plate 33 being in rotational connection with the side wall of the shaft body one 11, the surface of the ratchet plate 33 being connected with the side wall of the shaft body one 11 through a connecting spring 34, and a ratchet ring 35 fixedly connected with the inner wall of the magnetic cylinder 28 and matched with the ratchet plate 33.

[0025] More specifically, in the embodiment: when the shaft body one 11 rotates, the synchronous belt drives the ratchet plate 33 to deflect, in the detection state, the deflection of the ratchet plate 33 will not push the ratchet ring 35 to rotate, only the connecting spring 34 will be continuously compressed, and in the process of data acquisition, the brush plate 4 is inversely deflected and reset, the deflection of the ratchet plate 33 will drive the ratchet ring 35 to rotate, which will drive the magnetic cylinder 28 to rotate, and then drive the plurality of arc plates 29 to deflect, in the deflection process, the arc plate 29 will extrude the pin shaft 32, so that the pin shaft 32 collides with the rod group 30 to axially displace, so that the impact spring 31 is compressed, when the pin shaft 32 and the arc plate 29 are separated, at this time, under the elastic reset of the impact spring 31, the impact rod group 30 will quickly knock the end of the shaft body one 11, so that the shaft body one 11 vibrates, the vibration will be directly transmitted to the brush plate 4, through the vibration of the brush plate 4, the self-cleaning effect can be achieved, and the next pipe is ensured to be detected and processed. And without external force, that is, in the process of data acquisition, the magnetic cylinder 28 will be constrained by the magnetic force and will not rotate.

[0026] Working principle: the laser detection device for continuously measuring the wall thickness of the pipe uses the production pipe from the measuring frame 1, the port of the pipe is transported to the contact position of the brush plate 4 through the slide, the initial feeding process is completed, then the double-head motor 27 is started, the two groups of mechanical clamping rods 2 are driven to relatively displace by the rotation of the threaded rod 36, the pipe can be clamped, the stability of the pipe during measurement is maintained, and the positioning moving rod 24 also slides along the groove wall of the self-adaptive groove 26 during movement, when the size of the pipe is small, the mounting plate group 6 will be moved downward, so that the deflection center of the laser measuring plate 3 and the brush plate 4 is always located at the center axis of the pipe. Subsequently, the motor 14 is started to collect the wall thickness data. When the motor 14 is started, the laser measuring plate 3 is first displaced towards the brush plate 4, and the brush plate 4 is pre-deflected. As the motor 14 continues to rotate, the gear 21 is driven to rotate one revolution, and at this time the laser measuring plate 3 completes one revolution of rotation, and the wall thickness data of the pipe port is all collected. The obtained wall thickness data is transmitted to the data storage element 5 through Bluetooth for recording and processing. Subsequently, the brush plate 4 is inversely deflected and reset, and the laser measuring plate 3 moves away from the brush plate 4. Through the arrangement of the brush plate 4, the pipe port can be cleaned for one revolution, and the debris and attachments generated due to cutting are removed, which facilitates the accuracy of subsequent data collection of the laser measuring plate 3. The brush plate 4 has the characteristic of moving in advance. This can first ensure that the pipe port region moved by the laser measuring plate 3 is in a cleaned state, and the brush plate 4 can maintain a certain distance from the laser measuring plate 3. During the rotation of the laser measuring plate 3 and the data collection process, the laser data recording will not be disturbed due to the close distance between the two, the falling of debris, etc. During the non-detection process, the laser measuring plate 3 is relatively far away from the port position of the pipe, and only approaches the position during the start of detection. This can also ensure that the pipe will not come into contact with the laser measuring plate 3 during loading and unloading, and can avoid the damage of the instrument due to accidental contact, etc.
