Description

Technical Field

[0001] This application relates to the field of helical blade measurement technology, and in particular to a measurement device for wear-resistant helical blades of pavers. Background Technology

[0002] As a core, easily damaged component of pavers, the wear-resistant auger blades are in constant contact with aggregate mixtures. The blade sidewalls and ends are prone to wear and deformation, requiring periodic acquisition of profile data to assess their wear condition. Currently, most on-site profilometry for these auger blades requires complete disassembly and transport to a laboratory for testing using a fixed laser profilometer. This cumbersome disassembly and assembly process makes in-situ on-site testing impossible.

[0003] The few laser measurement devices available for on-site use mostly employ a preset, fixed detection posture. Due to uneven ground conditions at construction sites, the auger blades tend to tilt after the paver is parked. Traditional devices struggle to adjust the overall posture of the measurement actuator, leading to a misalignment of the laser detection reference and directly distorting the contour scan data. Furthermore, after operation, the surface of the paver auger blades is often covered with dirt, gravel, and other impurities. Most existing on-site laser detection equipment lacks a pre-cleaning mechanism, causing the measured surface to be obscured by these deposits. Consequently, the laser sensor captures the outer contour of the impurities rather than the true contour of the blade itself, introducing significant measurement errors. Furthermore, existing on-site testing equipment cannot simultaneously cover the tip and both sides of the helical blade's curved surface, often only able to complete sampling measurements of localized areas, leading to missed detections and an inability to obtain complete contour information of the entire blade area. Manually cleaning debris from the blade surface beforehand is not only labor-intensive and the cleaning effectiveness is affected by the operator's skill level, but it also increases auxiliary testing time, hindering the efficiency of on-site helical blade wear testing.

[0015] Compared with the prior art, the beneficial effects of the embodiments of the present invention are: This invention achieves dual-axis angle adjustment of the second U-plate and support plate by driving the first and second round rods to rotate using a first motor and a second motor, respectively. It can adaptively match the spatial tilt posture and helical angle of the wear-resistant auger blades according to the paver's tilt state caused by uneven ground at the construction site. Compared to existing traditional measuring equipment, which often has a fixed detection posture and cannot adapt to blade tilt conditions, this invention achieves synchronous adaptation of the overall posture of the cleaning component and the laser measurement component, completely solving the problems of cleaning dead angles, laser measurement misalignment, and inconsistent detection benchmarks caused by posture mismatch in traditional equipment.

[0016] This invention employs a combined cleaning method of spray water rinsing and wetting with mechanical scraping, which can thoroughly remove adhering impurities from the sidewalls and ends of blades, fully exposing the original contour surface of the blades. Furthermore, the cleaning operation can follow the blade rotation and the linear feed of the equipment to achieve full coverage without blind spots, effectively avoiding interference from impurities on laser detection. This provides a clean and complete working surface for subsequent laser contour scanning, fundamentally improving the accuracy, completeness, and stability of laser contour measurement data.

[0017] This invention features a multi-position adjustable laser measurement component. Utilizing the rotational adjustment functions of the sixth and seventh motors, along with the telescopic feed function of multiple sets of electric telescopic rods, it enables multi-angle and multi-positional attitude switching of the laser measurement sensor. Compared to existing technologies that can only perform simple detection at a single location on the blade and cannot comprehensively collect blade contour data, this invention can sequentially complete omnidirectional laser scanning measurements of the helical blade tip and the curved surfaces of both side walls. The equipment uses an electric slide rail to drive the measurement component to rotate and match the feed along with the blade, achieving comprehensive detection of the entire blade contour. This effectively solves the problems of limited detection range, missed detection of local contours, and incomplete data in traditional detection methods. Simultaneously, the equipment integrates a mobile component, allowing for free transport and rapid positioning of the work area. In-situ detection can be performed without disassembling the helical blade, significantly simplifying the detection process, improving work efficiency, and adapting to the needs of large-scale, routine blade contour detection operations at construction sites.

[0030] Working Principle: When it is necessary to perform contour measurement work on the wear-resistant auger blades inside the paver, the paver is parked at the construction site. First, the first electric telescopic rod 22 is started, driving the caster wheel 23 to extend outward along the first groove 21. After the caster wheel 23 extends outward from the bottom surface of the base plate 1, it provides support to the base plate 1. The operator pushes the base plate 1 as a whole to the working position below the side of the paver's auger blades. After reaching the position, the first electric telescopic rod 22 is retracted, and the caster wheel 23 is stored inside the first groove 21, so that the base plate 1 is directly supported on the construction ground. The ground at the construction site is uneven, and the paver will tilt after being parked, causing the wear-resistant auger blades inside to tilt in a spatial tilted posture along with the paver. The first motor 33 and the second motor 36 are started. The first motor 33 drives the first round rod 32 to rotate inside the first U-plate 31, which in turn drives the second U-plate 34 to complete the first dimensional angle deflection. The second motor 36 drives the second round rod 35 to rotate inside the second U-plate 34, which in turn drives the support plate 37 to complete the second dimensional angle deflection. The support plate 37 drives the mounting plate 38 to adjust its posture synchronously until the spatial tilt posture of the mounting plate 38 matches the overall spatial tilt posture of the wear-resistant spiral blade. Then the first motor 33 and the second motor 36 are turned off, completing the overall angle pre-adjustment of the cleaning component and the contour measurement component. The fourth motor 48 is started, which drives the corresponding first rotating rod 47 to rotate. The first rotating rod 47 drives the fourth electric telescopic rod 412 on the rod wall to swing synchronously with the first rotating rod 47, adjusting the spatial tilt angle of the corresponding scraper 413 so that the posture of the scraper 413 is adapted to the tilt angle of the curved surface of the side wall of the wear-resistant spiral blade. Then the fourth motor 48 is turned off. The fifth motor 411 is started, which drives the second rotating rod 410 to rotate. The second rotating rod 410 drives the fourth electric telescopic rod 412 on its rod wall to swing synchronously, adjusting the spatial tilt angle of the corresponding scraper 413 so that the posture of the scraper 413 is adapted to the tilt angle of the curved surface at the end of the wear-resistant spiral blade. Then the fifth motor 411 is turned off, thus completing the posture adaptation of each scraper 413 relative to the wear-resistant spiral blade. Start the third motor 45. The third motor 45 drives the third electric telescopic rod 43 to rotate on the side wall of the first side plate 42, which in turn drives the cleaning plate 44 to adjust its posture. First, adjust the nozzle 416 to the lower position of the cleaning plate 44. Then, continue to adjust the rotation angle of the third electric telescopic rod 43 through the third motor 45 so that the overall tilt posture of the cleaning plate 44 matches the spiral angle of the wear-resistant spiral blades. After completion, turn off the third motor 45.

[0031] The first electric slide rail 39 is controlled to drive the first slide plate 310 carrying the cleaning assembly to move, thereby moving the second electric telescopic rod 41, the first side plate 42, and the cleaning plate 44 as a whole to the working side of the wear-resistant spiral blade; the second electric telescopic rod 41 and the third electric telescopic rod 43 are controlled to start, driving the cleaning plate 44 to feed towards the wear-resistant spiral blade, so that the scraper 413 on the side of the first rotating rod 47 is correspondingly covered on the outer side wall of the wear-resistant spiral blade, while the scraper 413 on the side of the second rotating rod 410 is correspondingly arranged on the outer side of the end of the wear-resistant spiral blade. The fourth electric telescopic rod 412 is extended, driving each scraper 413 to abut against the side wall and end surface of the wear-resistant auger blade respectively; the water source inside the connecting shell 414 is sprayed outward through the connecting pipe 415 and the nozzle 416 to wash and wet the mud and gravel debris attached to the surface of the wear-resistant auger blade; the paver drives the wear-resistant auger blade to rotate, and the auger blade continuously passes through the washing area of ​​the nozzle 416 during the rotation and then reaches the working position of the scraper 413, where the scraper 413 scrapes away the mud and debris that have been wetted on the blade surface. While the wear-resistant spiral blades are rotating, the first electric slide rail 39 drives the first slide plate 310 of the cleaning component to move synchronously. The sliding plate's movement speed is matched with the rotation speed of the wear-resistant spiral blades, so that the nozzle 416 and scraper 413 can traverse the entire surface of the wear-resistant spiral blades to be inspected, completing the cleaning operation of dirt and debris on the entire circumferential surface of the wear-resistant spiral blades. After the cleaning operation is completed, the fourth electric telescopic rod 412 is controlled to retract and each motor is reset in reverse, driving the scraper 413 and cleaning plate 44 to reset to their initial positions. Then, the first electric slide rail 39 drives the first slide plate 310 of the cleaning component to return to the initial position. After the surface of the wear-resistant spiral blade is cleaned, the first electric slide rail 39 drives the other first slide plate 310, which carries the wear-resistant spiral blade contour measuring component 5, to move independently, thereby moving the fifth electric telescopic rod 51 and the second side plate 52 to the measurement work position of the wear-resistant spiral blade; the fifth electric telescopic rod 51 and the sixth electric telescopic rod 53 are started to transport the laser measuring sensor 59 to the measurement preparation position. The sixth motor 54 is started to drive the sixth electric telescopic rod 53 to rotate on the side wall of the second side plate 52 to adjust the spatial orientation of the sixth electric telescopic rod 53; the seventh motor 57 is started to drive the third round rod 56 to rotate inside the third U plate 55. The third round rod 56 drives the laser measuring sensor 59 to rotate synchronously through the side rod 58, thereby adjusting the orientation of the detection receiving surface of the laser measuring sensor 59 so that the laser measuring sensor 59 is aligned with the end contour surface to be measured of the wear-resistant spiral blade; The paver drives the wear-resistant auger blade to rotate continuously, and synchronously controls the first electric slide rail 39 to drive the first slide plate 310 carrying the measuring component to make linear displacement. The moving speed of the first slide plate 310 is matched with the rotation speed of the wear-resistant auger blade. The laser measuring sensor 59 outputs laser and receives the signal transmitted back from the measured surface, and scans and collects the complete contour of the end of the wear-resistant auger blade to complete the measurement of the end contour of the wear-resistant auger blade. After the end measurement of the wear-resistant spiral blade is completed, the seventh motor 57 is controlled to drive the third round rod 56 to rotate, which drives the side rod 58 and the laser measurement sensor 59 to complete the angle reversal and switch the detection orientation of the laser measurement sensor 59. With the extension and retraction adjustment of the fifth electric telescopic rod 51 and the sixth electric telescopic rod 53, the laser measurement sensor 59 is sent into the blade gap position of the wear-resistant spiral blade. Then, the sixth motor 54 is controlled to drive the sixth electric telescopic rod 53 to rotate, so that the detection end face of the laser measurement sensor 59 is perpendicularly aligned with the side wall of the wear-resistant spiral blade to be measured. The wear-resistant spiral blade is controlled to rotate again, and at the same time, the first electric slide rail 39 drives the first slide plate 310 of the measurement component to make a linear motion at a matching rate, and the laser measurement sensor 59 completes the contour scanning measurement of the side wall of the blade. After measuring one sidewall, repeat the above posture adjustment action. Adjust the spatial orientation and position of the laser measurement sensor 59 by using the seventh motor 57 and the sixth motor 54 so that the laser measurement sensor 59 is aligned with the other sidewall of the wear-resistant spiral blade. Use the same scanning method to complete the contour acquisition of the other sidewall. By summarizing the contour data of the blade tip and both sidewalls, complete detection of the overall contour of the wear-resistant spiral blade can be achieved. After all contour measurement work is completed, control each electric telescopic rod and each motor to reverse their movements in sequence, and reset the cleaning component and contour measurement component to their initial positions; control the first electric telescopic rod 22 to extend, and the caster wheel 23 to support the base plate 1 again, and move the base plate 1 out of the paver's working area, so that it can be transferred to the next paver to be measured, and the contour measurement work of the next set of wear-resistant spiral blades can be carried out.
