Description

Technical Field

[0001] The invention relates to the field of diameter measurement, and in particular to a steel wire rope infrared laser diameter detection device and a detection method. Background Art

[0002] With the development of industrial manufacturing and technology, the quality inspection requirements for production materials are becoming higher and higher. As the transmission component of many key equipment, the performance and status of wire ropes are directly related to the safety and efficiency of equipment operation. At the same time, the diameter of the wire rope directly affects the load-bearing capacity and service life of the equipment. Existing inspection equipment mostly uses contact measurement methods, and to a certain extent requires manual auxiliary operation, which greatly reduces the efficiency of inspection and the reliability of inspection results.

[0003] With the advancement of science and technology, technicians in related fields have also optimized the technical means for detecting the diameter of wire ropes. In order to make a more accurate comparison, a Chinese patent with publication number CN119437023A discloses a wire rope diameter measuring device and a measuring method thereof, including a measuring component, a first base and a measuring module; when in use, the two first bases are connected together by a partition plate with an inclined surface, which effectively avoids the spatial interference problem between the wire rope and the base. In addition, the measuring component is also provided with a measuring module equipped with a roller, which can accurately sense the position change of the roller caused by the change of the wire rope diameter based on capacitance or electromagnetic principles, thereby realizing accurate measurement of whether the wire rope diameter is compliant.

[0004] However, when using the above-mentioned prior art to measure the wire rope, there are still the following problems: The above-mentioned device drives the roller to press against the outside of the wire rope to be measured, and then detects the change in the position of the roller caused by the change in the diameter of the wire rope and the change in the electrical signal of the displacement member when the roller position changes, thereby achieving accurate measurement of whether the wire rope diameter is compliant. However, when it is in use, it directly detects the position of the roller pressing against wire ropes of different diameters to measure the wire rope diameter. In the process of the roller rolling and sliding along the outer side of the wire rope, the surface of the wire rope is not a smooth arc surface, and the wire rope may sway during operation, resulting in unstable contact between it and the roller, affecting the measurement accuracy. At the same time, the vibration generated during the sliding of the wire rope may be transmitted to the roller, affecting the contact stability between the roller and the wire rope, causing the electrical signal at the displacement member to continuously change, affecting the measurement efficiency.

[0005] Therefore, based on the above-stated viewpoint, there is still room for optimization of the existing technical means for measuring wire ropes. Summary of the invention

DETAILED DESCRIPTION

[0032] The following is combined with Figure 1 To Attachment Figure 8 Embodiments of the present invention are described in detail.

[0033] The embodiment of the present application discloses an infrared laser diameter detection device and method for a wire rope, which illustrates that the present application is mainly used in the process of measuring the diameter of the wire rope, and achieves the effect of detecting the diameter of the wire rope in terms of technical effect; in particular, during the measurement process, the effect of measuring the diameter of the wire rope is achieved by a non-contact infrared laser, which effectively avoids the measurement error caused by mechanical vibration during the measurement process; and, the present application also automatically drives the laser emitting end and the laser receiving end on the arc plate to rotate circumferentially relative to the wire rope through the cooperation between the wire rope, the driven sliding rod and the cleaning arc block, so as to improve the accuracy of the measurement data.

[0034] Reference Figure 1 As shown, a wire rope infrared laser diameter detection device includes a mounting base 1, and a measuring component 2 for measuring the diameter of the wire rope is connected to the mounting base 1. When in use, the mounting base 1 and the measuring component 2 are moved to the wire rope to be measured, and the diameter of the wire rope is measured by driving the measuring component 2 and the wire rope to perform relative sliding motion.

[0035] Reference Figures 2 to 4As shown, the measuring assembly 2 is used to measure the diameter of the wire rope; specifically, the measuring assembly 2 includes: The housing 20 is connected to the mounting seat 1 in a limiting manner, and a limiting roller 21 is symmetrically provided at the end of the housing 20 in a limiting manner.

[0036] The laser emitting end 22 is limit-connected to the inner edge of the housing 20 .

[0037] The laser receiving end 23 is limit-connected to the inner edge of the housing 20 and is arranged corresponding to the laser emitting end 22 , and is used for receiving the laser signal of the laser emitting end 22 .

[0038] When in use, the shell 20 is sleeved on the outside of the steel wire rope to be measured, forming a state in which the steel wire rope is clamped in the middle, and then the laser emitting end 22 is enabled to emit infrared laser to the steel wire rope. The laser beam is reflected on the surface of the steel wire rope, and the reflected light beam is received by the laser receiving end 23, forming an approximately triangular relationship between the laser emitting end 22, the steel wire rope and the laser receiving end 23. Since the steel wire rope is a curved surface, the direction of the reflected light will change according to the surface curvature. When the diameter of the steel wire rope changes, the reflection point of the laser beam on the surface of the steel wire rope will change, causing the position of the reflected light spot on the receiving end to shift, thereby changing the side length and angle relationship of the triangle.

[0039] Before actual measurement, determine the laser emission angle α of the laser emitting end 22 (usually a known constant), the relative angle θ between the reflected light received by the laser receiving end 23 and the normal of the receiving end (usually changes according to the laser beam emission angle and is a variable), and the distance L between the laser emitting end 22 and the laser receiving end 23 (usually a known constant).

[0040] According to the law of reflection, the reflection angle is equal to the incident angle, so the angle between the reflected light and the normal of the wire rope surface is equal to the laser emission angle.

[0041] The relationship between the position offset Δx of the reflected light spot on the receiving end and the reflection angle α is: Δx=L*tan*(α).

[0042] The relationship between the reflection angle α and the wire rope straightness d can be obtained by geometric deduction: α=θ−arcsin(d / 2R).

[0043] Where R is the radius of curvature of the laser beam.

[0044] By measuring the position offset Δx of the reflected light spot on the receiving end, the reflection angle α can be calculated: α=arctan(Δx / L).

[0045] Substituting into the above geometric relationship, we can obtain: d / 2R=sin(θ−arctan(Δx / L)).

[0046] Finally, the calculation formula for the wire rope diameter d is: d=2R*sin(θ−arctan(ΔxL)).

[0047] Therefore, according to the geometric relationship between the laser emitting end 22, the steel wire rope and the laser receiving end 23, the diameter of the steel wire rope can be calculated, thereby achieving the effect of measuring the diameter of the steel wire rope.

[0048] Reference Figures 2 to 4 As shown, the housing 20 includes two symmetrically arranged mounting ring plates 200, wherein any one of the mounting ring plates 200 is limitedly connected to the mounting seat 1, and the two mounting ring plates 200 are detachably matched to form a cylindrical housing 20 structure, and the diameter of the cylindrical housing 20 at both ends is smaller than the diameter of the middle. During use, after the cylindrical housing 20 formed by the two mounting ring plates 200 clamps the wire rope in the middle, the laser emitting end 22 and the laser receiving end 23 in the housing 20 cooperate to complete the effect of non-contact measurement of the wire rope diameter, effectively avoiding the influence of mechanical vibration caused by the position offset of the wire rope end when the housing 20, the measuring component 2 and the wire rope are driven to slide relative to each other, thereby improving the accuracy of the measurement result; at the same time, by clamping the wire rope by the housing 20, the interference of direct strong light from the environment on the infrared laser signal can also be effectively avoided, further improving the accuracy of the measurement result.

[0049] Reference Figures 4 to 6 As shown, in order to improve the stability when driving the wire rope and the measuring component 2 and the shell 20 to slide relative to each other, the two mounting ring plates 200 are correspondingly assembled to form a cylindrical shell 20 and the wire rope is clamped therein. The limiting roller 21 at the end of the mounting ring plate 200 will abut against the wire rope, and the limiting roller 21 is driven by the wire rope to rotate to achieve the effect of reducing the friction between the wire rope and the shell 20, thereby further reducing the problem of large mechanical vibration caused by the friction between the wire rope and the shell 20 affecting the measurement accuracy when the wire rope and the shell 20 slide relative to each other.

[0050] Furthermore, the direct friction between the wire rope and the housing 20 can be reduced by rotating the limit roller 21 and contacting the wire rope. However, when the wire rope drives the limit roller 21 to rotate, the contact point between the limit roller 21 and the wire rope will continue to change. Although it can effectively prevent the mechanical vibration from being directly transmitted to the measuring component 2, the limit roller 21 will also generate certain vibrations when it is driven to rotate. At the same time, under normal circumstances, the wire rope is not a completely smooth arc surface. Therefore, during the process of the limit roller 21 and the wire rope continuously rotating and contacting, it is very likely that the limit roller 21 and the wire rope will generate sudden impact or vibration due to the uneven surface of the wire rope. Movement, thereby amplifying the vibration of the wire rope and the housing 20 during relative sliding, forming a resonance effect, and then affecting the measurement of the measuring component 2. Therefore, in order to avoid the above-mentioned problem, limit ring plates 24 are symmetrically connected to both ends of the mounting ring plate 200, and a limit sleeve 240 is commonly connected between the limit ring plate 24 and the mounting ring plate 200. A connecting slide rod 241 corresponding to the limit roller 21 is penetrated in the limit sleeve 240, and one end of the connecting slide rod 241 located in the limit sleeve 240 is connected to a stop block 242, and a buffer spring 243 located between the connected stop block 242 and the limit sleeve 240 is sleeved on the connecting slide rod 241.

[0051] When in use, after the limiting roller 21 is in contact with the wire rope, driven by the connected buffer spring 243, the connecting slide bar 241 and the limiting roller 21 tend to always slide towards the direction close to the middle wire rope. When impact or vibration occurs between the limiting roller 21 and the wire rope, that is, when the limiting roller 21 is pushed by the wire rope to slide away from the wire rope, the limiting roller 21 is pushed by the wire rope, driving the connected connecting slide bar 241 and the stop block 242 to slide, and compressing the connected buffer spring 243. The buffer spring 243 absorbs vibration energy during the compression process and reduces the transmission of vibration. When the limit roller 21 slides to a certain extent, the connecting slide rod 241 no longer pushes the stop block 242 and the buffer spring 243. At the same time, the buffer spring 243 will return to its original state and release the stored elastic potential energy, further reducing the duration of vibration. Through the elastic deformation of the connected buffer spring 243 itself, the impact energy generated when the limit roller 21 is pushed is absorbed, thereby reducing the transmission of vibration and achieving a buffering effect.

[0052] Reference Figures 4 to 7As shown, one of the stop blocks 242 is connected to a connecting guide plate 25 that is inserted through the mounting ring plate 200, and an arc-shaped cleaning arc block 250 is provided at the upper limit of the connecting guide plate 25. When in use, after the two mounting ring plates 200 are assembled and clamped on the outside of the steel wire rope to be measured, the limiting roller 21 drives the connecting slide bar 241 and the stop block 242 to slide in the direction close to the middle steel wire rope under the drive of the connected buffer spring 243, and the sliding of the stop block 242 drives the connected connecting guide plate 25 and the cleaning arc block 250 to slide synchronously, so that the cleaning arc block 250 contacts the outside of the steel wire rope, and as the relative position between the steel wire rope to be measured and the housing 20 is driven to slide, the cleaning arc block 250 slides synchronously on the outside of the steel wire rope, thereby achieving the effect of scraping off impurities such as oil stains attached to the surface of the steel wire rope.

[0053] Reference Figures 4 to 7 As shown, under normal circumstances, a steel wire rope is a rope strand structure formed by twisting multiple steel wires around a strand core, which is mostly in a twisted curled shape. Therefore, the outer side of the steel wire rope strands after twisting will usually also correspond to the multiple steel wires to form multiple twisted grooves located between any two adjacent steel wires. Therefore, in order to synchronously scrape off the oil stains between the grooves to avoid affecting the accuracy of subsequent diameter measurement, a driven slide bar 251 is slidably provided on the cleaning arc block 250. The driven slide bar 251 is arranged in an arc shape at one end of the steel wire rope near the middle, corresponding to the groove, and is slidably inserted in the groove. As an optional embodiment, the number of driven slide bars 251 can be set to multiple corresponding to the number of steel wire rope strands.

[0054] When in use, while driving the steel wire rope and the housing 20 to slide relative to each other, the arc end of the driven slide bar 251 and the cleaning arc block 250 always abut against the outside of the steel wire rope. As the relative positions of the steel wire rope, the driven slide bar 251 and the cleaning arc block 250 change, the oil stains on the surface of the steel wire rope and in the grooves are scraped and cleaned, so as to avoid affecting the accuracy of the subsequent measurement of the steel wire rope diameter.

[0055] It should be noted that, since the groove on the outside of the wire rope is twisted, when the wire rope and the driven slide bar 251 are driven to slide relative to each other, the driven slide bar 251 will deflect along the twisted groove on the wire rope. Therefore, in order to avoid affecting the cleaning effect of the driven slide bar 251 on the groove on the wire rope, Figures 4 to 7As shown, a guide frame plate 252 is connected to the upper limit position of the mounting ring plate 200, and a circular arc-shaped guide slot 2520 is formed on the guide frame plate 252. A telescopic link 253 connected to the cleaning arc block 250 is slidably inserted in the guide slot 2520, and the telescopic section of the telescopic link 253 is connected to the cleaning arc block 250. During use, when the driven slide bar 251 slides along the groove outside the wire rope, the driven slide bar 251 will deflect along the twisted groove, and the deflection of the driven slide bar 251 drives the connected cleaning arc block 250 and the telescopic link 253 to deflect synchronously.

[0056] Reference Figures 4 to 8 As shown, there are several arc plates 26 for sliding limit in the shell 20, the laser emitting end 22 is limitedly connected to the arc plate 26, and the laser emitting end 22 is provided with several arc plates 26 corresponding to the laser emitting end 22, one of which is close to the driven sliding rod 251 and is commonly connected with a driven lever 260 between the driven sliding rod 251, and two adjacent arc plates 26 are connected by a connecting rod 261.

[0057] When in use, after the driven slide bar 251 deflects along the groove on the steel wire rope, it drives the connected driven slide bar 251 to deflect synchronously, and the driven slide bar 251 rotates to drive the connected driven lever 260 and the arc plate 26 to rotate synchronously. The rotation of the arc plate 26 drives all the correspondingly connected arc plates 26 to rotate synchronously through a plurality of connecting rods 261. The rotation of the arc plate 26 drives the laser emitting end 22 connected thereto to rotate synchronously, thereby achieving the effect of adjusting the relative position between the laser emitting end 22 and the steel wire rope to be measured, so that the plurality of laser emitting ends 22 and the laser receiving end 23 on the two corresponding arc plates 26 rotate circumferentially relative to the steel wire rope, so as to complete the effect of measuring the nominal diameter of the steel wire rope.

[0058] Reference Figures 4 to 8 As shown, a limit slider 27 is sleeved on the end of the driven slide rod 251 away from the middle wire rope, a guide sleeve 270 connected to the cleaning arc is sleeved on the limit slider 27, and a compression spring 271 located between the limit slider 27 and the guide sleeve 270 is sleeved on the driven slide rod 251.

[0059] In the initial state, the compression spring 271 in the guide sleeve 270 is in a partially compressed state, so that the compression spring 271 has a tendency to always drive the connected limit slider 27 and the driven slide bar 251 to slide toward the direction close to the middle wire rope, so that the driven slide bar 251 always sticks to the groove during the sliding process along the groove on the wire rope, thereby preventing the driven slide bar 251 from detaching from the groove on the wire rope. At the same time, the elastic deformation of the compression spring 271 also forms a buffering and absorbing effect on the vibration of the connected driven slide bar 251 during the sliding process to a certain extent.

[0060] Furthermore, when the driven slide 251, the cleaning arc block 250 and the telescopic link 253 are driven to deflect, they will deflect as a whole with the wire rope as the axis. In order to prevent the connecting guide plate 25 limited on the mounting ring plate 200 from affecting the overall deflection of the driven slide 251, the cleaning arc block 250 and the telescopic link 253, a sliding frame 272 is connected to the end of the connecting guide plate 25 close to the cleaning arc block 250, and a sliding arc block 273 is provided in the sliding frame 272 for sliding limit, and a driven link 274 is commonly provided between the sliding arc block 273, the connecting guide plate 25 and the guide sleeve 270; when in use, the deflection of the cleaning arc block 250 and the driven slide 251 drives the connected sliding arc block 273 to slide circumferentially on the sliding frame 272 synchronously.

[0061] In addition, the present invention also provides a wire rope infrared laser diameter detection method, comprising the following steps: S1: Move the mounting base 1 and the housing 20 to the vicinity of the steel wire rope to be measured, so that the housing 20 is sleeved on the outside of the steel wire rope to form a clamping state. After the ring plate 200 is installed and assembled into the housing 20, the limiting roller 21 is pressed against the surface of the steel wire rope to support and limit the steel wire rope to be measured, ensuring that the relative position of the equipment and the steel wire rope is stable.

[0062] S2: During the measurement process, the laser emitting end 22 emits an infrared laser, the laser beam irradiates the surface of the steel wire rope and is reflected, the laser receiving end 23 receives the reflected beam, and the diameter of the steel wire rope is calculated based on the geometric relationship between the laser emitting end 22, the steel wire rope and the laser receiving end 23.

[0063] S3: driving the measuring component 2 and the steel wire rope to perform relative sliding motion, ensuring that the laser beam can scan the entire circumference of the steel wire rope, thereby achieving a comprehensive measurement of the diameter of the steel wire rope.

[0064] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered as exemplary and non-restrictive in all respects.

[0065] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
