Description

Technical Field

[0001] This invention relates to the field of material quality testing technology, and in particular to an engineering tire surface testing device. Background Technology

[0002] Engineering tire surface inspection technology is a key technology that uses automated methods such as vision, optics, or various sensors to perform high-precision defect identification on tire treads, sidewalls, and other parts. Its purpose is to monitor the tire surface in real time for defects such as scratches, cracks, abnormal wear, or embedded foreign objects, thereby eliminating safety hazards at an early stage and preventing downtime of construction machinery or safety accidents caused by tire failure. The significance of this technology lies not only in ensuring construction safety and operational continuity, but also in significantly reducing operating costs by extending tire lifespan and optimizing maintenance cycles, making it an important link in realizing intelligent operation and maintenance and inherent safety of construction machinery.

[0003] In existing technologies, conventional testing equipment can only inspect the inner or outer side of a tire individually. After inspecting one side, the tire must be manually flipped before inspecting the other side, a cumbersome and time-consuming process. Furthermore, the equipment's structural layout may be loose or require more space for operation and flipping, resulting in low overall space utilization. Moreover, existing testing devices typically rely on bolts, clamps, and other locking structures for fixing, making tire installation and removal complex and laborious. During testing, the number of fixing points may be insufficient or the methods may be limited, making it difficult to provide sufficient and balanced restraint during tire rotation. This can easily lead to slight tire wobble or displacement, affecting the comprehensiveness and stability of the inspection. In addition, conventional equipment is designed for specific tire sizes and specifications; adapting to different sizes requires changing parts or making complex adjustments, resulting in poor flexibility. Summary of the Invention

[0021] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the invention, and should not be construed as limiting the invention. Rather, embodiments of the invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0022] like Figures 1 to 7 As shown in the figure, an embodiment of the present invention proposes an engineering tire surface inspection device. The inspection device includes: an inspection platform 1, a drive mechanism 2, and a support assembly 3. The drive mechanism 2 is mounted on the surface of the inspection platform 1. A rotating column 9 is provided at the top of the drive mechanism 2. The drive mechanism 2 is used to clamp the side of the engineering tire to be tested, and the drive mechanism 2 is also used to control the engineering tire to be tested to rotate. There are four rotating columns 9, and the top of each rotating column 9 is at the same horizontal height. The support assembly 3 is installed at the rear end of the inspection platform 1. The testing device also includes a support mechanism, which includes an inner support mechanism 4 and an outer support mechanism 5. The support assembly 3 is used to support and install the inner support mechanism 4 and the outer support mechanism 5. The end of the inner support mechanism 4 is provided with an inner support wheel 35, which is used to contact and fit with the inner wall of the tire to be tested. The end of the outer support mechanism 5 is provided with an outer support wheel 39, the side of which is used to fit with the surface of the tire to be tested, and the length of the outer support wheel 39 is greater than that of the inner support wheel 35.

[0023] When using the tire surface inspection device, first rotate the inner support mechanism 4 towards the top, so that the inner support wheel 35 points vertically upward. At this time, the tire to be tested can be pushed horizontally in a vertical posture, so that the tire to be tested is fitted onto the outer area of ​​the inner support mechanism 4. Then, insert the tire to be tested vertically downward into the drive mechanism 2 and lock it in place by the four sets of conical rods 10. Finally, manually control the outer support mechanism 5 to pull it outward, while controlling the inner support mechanism 4 to rotate and reset, so that the inner support wheel 35 can abut against the inner wall area of ​​the tire to be tested. Then, release the outer support mechanism 5, and insert the positioning rod 38 in the outer support mechanism 5 into the positioning sleeve. Finally, start the drive mechanism 2 to control the rotation of the tire to be tested, and use the laser ranging module 40 to test whether there are bulges or dents on the surface of the tire to be tested.

[0024] In this embodiment, the drive mechanism 2 includes: The test platform 1 is equipped with a drive motor 6, a transmission box 7, a rotating column 9, and a conical rod 10. The surface of the test platform 1 is screwed with a transmission box 7. There are two transmission boxes 7, and the top of each transmission box 7 is inserted with a rotating column 9. The top of each rotating column 9 is integrally formed with a conical rod 10. The specifications of each rotating column 9 and conical rod 10 are the same. The test tire is vertically inserted and installed from the middle area of ​​the four conical rods 10. The drive mechanism 2 also includes an opening 8, which is located on the side of the transmission box 7. The outer shell of the drive motor 6 is screwed to the bottom of the detection table 1, and the output shaft of the drive motor 6 passes through the bottom of the detection table 1 into the interior of one of the transmission boxes 7. The drive motor 6 is used to control each rotating column 9 to rotate.

[0025] The drive mechanism 2 also includes: The gear consists of a toothed belt 11, a first driving gear 12, a second driving gear 13, a linkage gear 14, a driven gear 15, and a central column 16. Each of these components is installed inside the transmission box 7. The first driving gear 12 and the second driving gear 13 mesh with each other, and the surfaces of both the first driving gear 12 and the second driving gear 13 are connected to the linkage gear 14.

[0026] The side of the linkage gear 14 is fitted with a toothed belt 11, and the inner side of the other end of the toothed belt 11 is fitted with a driven gear 15. The inner sides of both the linkage gear 14 and the driven gear 15 are fitted with a central column 16, and the bottom end of the central column 16 and the rotating column 9 are integrally formed. The drive motor 6 drives the first drive gear 12 to rotate via the drive shaft. The first drive gear 12 is used to control the rotation of the second drive gear 13. Both the first drive gear 12 and the second drive gear 13 are used to drive the linkage gear 14 to rotate. The linkage gear 14, in conjunction with the toothed belt 11, is used to control the driven gear 15 to rotate in the same direction.

[0027] The installation process of the test tire is simpler and faster. The test tire is directly inserted from the top into the drive mechanism 2, and then the inner layer abutting mechanism is manually controlled to abut against the inner wall of the test tire. The entire installation process does not require the use of a locking structure, which simplifies the process. Moreover, throughout the subsequent testing process, it can always provide multiple points of restriction around the test tire, improving the stability of tire movement during the testing process and indirectly improving the comprehensiveness of the testing range.

[0028] Specifically, after starting the drive motor 6, the output shaft rotates, which in turn drives the first drive gear 12 to rotate. Since the first drive gear 12 and the second drive gear 13 mesh, the second drive gear 13 can be directly driven to operate. Ultimately, each linkage gear 14, toothed belt 11, and driven gear 15 are controlled to rotate synchronously. Through this process, each central column 16 can be rotated directly, thereby driving the outer rotating column 9 and the conical rod 10 to rotate. Since the conical rod 10 or the rotating column 9 is in a clamping state for the test tire, the test tire can be controlled to rotate directly through this process. Furthermore, since the inner support mechanism 4 has provided a shield from one side of the test tire, even if the bottom drive mechanism 2 controls the test tire to rotate away from the inner support mechanism 4, it can be ensured that the test tire will not move horizontally and cause it to disengage from the drive mechanism 2.

[0029] In this embodiment, the support component 3 includes: The upright plate 17, the supporting guide rail 18, and the slide groove 19 are provided. The bottom of the upright plate 17 is welded and fixed to the side of the detection table 1. The top of the upright plate 17 is screwed with the supporting guide rail 18. The inner side of the supporting guide rail 18 is provided with the slide groove 19. The upright plate 17 is used to install and fix the supporting guide rail 18. The inner side abutting mechanism 4 and the outer side abutting mechanism 5 are both inserted into the slide groove 19. The support assembly 3 also includes a first spring rod 20 and a second spring rod 22, both of which are installed inside the slide groove 19 and are respectively inserted into the two end areas of the slide groove 19.

[0030] The outer abutment mechanism 5 includes: The extension rod 37, positioning rod 38, outer top wheel 39, and laser ranging module 40 are provided. The extension rod 37 passes through the inside of the slide groove 19. The end of the second spring rod 22 is welded and fixed to the side of the extension rod 37. The laser ranging module 40 is also installed on the surface of the extension rod 37. The laser ranging module 40 is horizontally irradiated towards the other end along the direction of the slide groove 19.

[0031] An outer top wheel 39 is installed at the end of the extension rod 37, and a positioning rod 38 is provided at the other end of the extension rod 37. The positioning rod 38 and the extension rod 37 are perpendicular to each other. The cross-section of the extension rod 37 is rectangular, and the top and bottom of the extension rod 37 are in contact with the inner wall of the slide groove 19. The second spring rod 22 is used to push the outer top mechanism 5 toward the inner top mechanism 4.

[0032] The power system installed in the inner top-supporting mechanism 4 enables comprehensive inspection of the surface of the test tires of different sizes and specifications, thus expanding the scope of application. Furthermore, when testing tires of different sizes and specifications, the movement between the two top-supporting mechanisms is always limited to the required range of motion, reducing the interference caused by the tire's own elasticity on the testing elements and improving the accuracy of the test.

[0033] Specifically, the support mechanism supports the inner and outer support mechanisms 4 and 5 through the top groove 19, allowing both the inner and outer support mechanisms 4 and 5 to be manually moved horizontally along the inside of the groove 19. Since the first spring rod 20 and the second spring rod 22 are provided inside the groove 19, the inner support mechanism 4 and the outer support mechanism 5 can achieve the purpose of clamping the inner and outer sides of the tire to be tested without applying other external forces.

[0034] Furthermore, under the action of the second spring rod 22, the outer push-back mechanism 5 can always press the outer push-back wheel 39 at the end against the surface of the tire under test. When a bulge appears on the surface of the tire under test, it will cause the second spring rod 22 to be compressed, thereby changing the position of the laser ranging module 40. The laser ranging module 40 always irradiates the surface of the push collar 21. Therefore, after the bulge appears, the distance data obtained by the laser ranging module 40 will increase, thereby generating an alarm signal. The laser ranging module 40 is an existing mature technology and is not within the protection scope of this invention. Therefore, the internal structure principle and circuit structure specifications of this invention will not be described in detail here. This embodiment only uses the ranging function it provides.

[0035] In this embodiment, the inner side abutting mechanism 4 includes: The system comprises a first end plate 26, a baffle 27, a limiting groove 28, a second end plate 29, a switching motor 30, and a lead screw 31. The first end plate 26 has a baffle 27 integrally formed on its side, and the end of the baffle 27 has a second end plate 29 integrally formed on its end. The switching motor 30 is screwed onto the surface of the second end plate 29, and the output end of the switching motor 30 is connected to the lead screw 31. The end of the lead screw 31 is embedded into the surface of the first end plate 26 through a bearing. Both ends of the baffle 27 are perpendicular to the first end plate 26 and the second end plate 29. The surface of the baffle 27 has a limiting groove 28.

[0036] The inner side abutting mechanism 4 also includes: The first end plate 26 has an integrally formed extension shaft 23 on its surface. The extension shaft 23 is fitted with a push collar 21 on its surface. The extension shaft 23 is welded to the end of the extension shaft 23. The rotation rod 24 is welded to the end of the extension shaft 23. The rotation rod 24 has a positioning channel 25 on its inner side. Both ends of the positioning channel 25 are open. The positioning rod 38 is used to insert into the interior of the positioning channel 25. The end of the first spring rod 20 and the push collar 21 are welded and fixed. The rotating pull rod 24, together with the extension shaft 23, is used to drive the entire inner side push mechanism 4 to rotate.

[0037] The inner side abutting mechanism 4 also includes: The components include a slider 32, a top support rod 33, a threaded sleeve 34, an inner top support wheel 35, and a sandwich layer 36. One end of the top support rod 33 is integrally formed with the slider 32, and the other end of the top support rod 33 is equipped with an inner top support wheel 35. A threaded sleeve 34 is provided on the side of the top support rod 33. The lead screw 31 passes through the inside of the threaded sleeve 34, and the top support rod 33 passes through the inside of the limiting groove 28. A sandwich layer 36 is provided in the middle of the inner top support wheel 35. The end of the top support rod 33 is movably connected to a rod in the middle of the sandwich layer 36 through a bearing.

[0038] An inner support mechanism 4 and an outer support mechanism 5 are provided at the top of the support component 3. Through the two sets of inner and outer support mechanisms, the surface of the tire to be tested can be clamped and fixed directly. With the help of the laser ranging module 40, the surface of the tire to be tested can be checked for bulges or dents. The simultaneous detection process of the inner and outer sides is realized. The equipment occupies little space and improves the space utilization rate.

[0039] Specifically, in use, by controlling the rotation of the lever 24, the entire inner push-up mechanism 4 can be directly driven to rotate, thereby changing whether the inner push-up wheel 35 is pressed against the inner wall of the tire under test. When the inner push-up wheel 35 is pressed against the inner wall of the tire under test, the switching motor 30 and the drive motor 6 are started, which can directly control the rotation of the tire under test and change the position of the inner push-up wheel 35 pressing against the inner wall of the tire under test, so as to achieve the purpose of complete coverage testing of tires of different widths.
