Description

Technical Field

[0001] The present 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 requirements for quality inspection of production materials are becoming increasingly stringent. As a transmission component of many key equipment, the performance and condition of wire ropes are directly related to the operational safety and efficiency of the equipment. 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 requires manual operation to a certain extent, which greatly reduces the efficiency of inspection and the reliability of test results.

[0003] With the advancement of science and technology, technicians in related fields have also optimized the technical means for detecting wire rope diameters. In order to make a more accurate comparison, a Chinese patent with publication number CN119437023A discloses a wire rope diameter measuring device and a measurement 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, effectively avoiding 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, the following problems still exist:

[0005] 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 wire rope diameter 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.

[0006] 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

[0036] The following is combined with Figure 1 To the attached Figure 8 The embodiments of the present invention are described in detail.

[0037] The embodiments of the present application disclose an infrared laser diameter detection device and method for a wire rope, which explains that the present application is mainly used in the process of measuring the diameter of the wire rope, and technically achieves the effect of detecting the diameter of the wire rope; 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 slide rod and the cleaning arc block, so as to improve the accuracy of the measurement data.

[0038] Reference Figure 1 The device, shown here, is an infrared laser diameter measuring device for steel wire ropes. It includes a mounting base 1, to which is connected a measuring assembly 2 for measuring the diameter of the steel wire rope. During use, the mounting base 1 and measuring assembly 2 are moved to the steel wire rope to be measured. The measuring assembly 2 and the steel wire rope are driven to slide relative to each other to measure the diameter of the steel wire rope.

[0039] Reference Figures 2 to 4 As shown, the measuring assembly 2 is used to measure the diameter of the wire rope; specifically, the measuring assembly 2 includes:

[0040] The housing 20 is connected to the mounting base 1 in a limited manner, and a limiting roller 21 is symmetrically provided on the end of the housing 20 for limiting purposes.

[0041] The laser emitting end 22 is connected to the inner edge of the housing 20 in a limiting manner.

[0042] 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 to receive the laser signal from the laser emitting end 22 .

[0043] During use, the shell 20 is placed 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 activated to emit an 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 this triangle.

[0044] 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 line of the receiving end (usually a variable that changes according to the laser beam emission angle), and the distance L between the laser emitting end 22 and the laser receiving end 23 (usually a known constant).

[0045] 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.

[0046] 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).

[0047] The relationship between the reflection angle α and the wire rope straightness d can be obtained by geometric deduction: α = θ − arcsin (d / 2R).

[0048] Where R is the radius of curvature of the laser beam.

[0049] By measuring the position offset Δx of the reflected light spot on the receiving end, the reflection angle α can be calculated:

[0050] α=arctan(Δx / L).

[0051] Substituting the above geometric relationship, we can obtain: d / 2R=sin(θ−arctan(Δx / L)).

[0052] Finally, the calculation formula for the wire rope diameter d is: d=2R*sin(θ−arctan(ΔxL)).

[0053] 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.

[0054] 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 positionally connected to the mounting base 1, and the two mounting ring plates 200 are detachably coupled to form a cylindrical housing 20 structure, wherein the diameter of the cylindrical housing 20 at both ends is smaller than the diameter of the central portion. During use, after the cylindrical housing 20 formed by the two mounting ring plates 200 clamps the wire rope in the central portion, the laser emitting end 22 and the laser receiving end 23 in the housing 20 cooperate to achieve 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 assembly 2, and the wire rope are driven to slide relative to each other, thereby improving the accuracy of the measurement results. At the same time, the way the housing 20 clamps the wire rope can also effectively prevent the interference of direct strong ambient light on the infrared laser signal, further improving the accuracy of the measurement results.

[0055] Reference Figures 4 to 6 As shown, in order to improve the stability when driving the relative sliding between the wire rope and the measuring component 2 and the shell 20, 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 be pressed 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 generated by the friction between the wire rope and the shell 20 when the wire rope and the shell 20 slide relative to each other, affecting the measurement accuracy.

[0056] 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 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, in the process of continuous rotation and contact between the limit roller 21 and the wire rope, it is very likely that the uneven surface of the wire rope will cause sudden impact or vibration between the limit roller 21 and the wire rope. The movement amplifies the vibration of the wire rope and the housing 20 during relative sliding, forms a resonance effect, and then affects the measurement of the measuring component 2. Therefore, in order to avoid the above-mentioned problem, the limiting ring plates 24 are symmetrically connected to both ends of the mounting ring plate 200, and the limiting sleeve 240 is commonly connected between the limiting ring plate 24 and the mounting ring plate 200. The limiting sleeve 240 is provided with a connecting slide rod 241 corresponding to the limiting roller 21. One end of the connecting slide rod 241 located in the limiting sleeve 240 is connected to a stop block 242, and the connecting slide rod 241 is provided with a buffer spring 243 located between the connected stop block 242 and the limiting sleeve 240.

[0057] During use, after the limiting roller 21 is pressed against the wire rope, driven by the connected buffer spring 243, the connecting slide bar 241 and the limiting roller 21 always tend to slide toward the middle of the 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, reducing the transmission of vibration. When the limiting 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, releasing 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 limiting roller 21 is pushed is absorbed, thereby reducing the transmission of vibration and achieving a buffering effect.

[0058] 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 on the upper limit of the connecting guide plate 25. During use, after the two mounting ring plates 200 are spliced ​​and clamped on the outside of the wire rope to be measured, the limiting roller 21, driven by the connected buffer spring 243, drives the connecting slide bar 241 and the stop block 242 to slide toward the direction close to the middle wire rope. 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 wire rope. As the relative position between the 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 wire rope, thereby achieving the effect of scraping off impurities such as oil stains attached to the surface of the wire rope.

[0059] Reference Figures 4 to 7 As shown, under normal circumstances, the wire rope is a rope structure formed by twisting multiple steel wires around a strand core, which is mostly in a twisted and curled shape. Therefore, the outer side of the twisted wire rope strands 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 and dirt between the grooves to avoid affecting the accuracy of subsequent diameter measurement, a driven slide 251 is slidably provided on the cleaning arc block 250. The groove corresponding to one end of the driven slide 251 near the middle wire rope is set to an arc shape, and is slidably inserted in the groove. As an optional embodiment, the number of driven slides 251 can be set to multiple corresponding to the number of wire rope strands.

[0060] During use, when the wire rope and the housing 20 are driven to slide relative to each other, the arc end of the driven slide 251 and the cleaning arc block 250 always contact the outside of the wire rope. As the relative position between the wire rope, the driven slide 251 and the cleaning arc block 250 changes, the oil stains on the surface of the wire rope and in the groove are scraped and cleaned to avoid affecting the accuracy of the subsequent measurement of the wire rope diameter.

[0061] 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. 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. The guide frame plate 252 is formed with an arc-shaped guide groove 2520. A telescopic link 253 connected to the cleaning arc block 250 is slidably inserted into the guide groove 2520. The telescopic section of the telescopic link 253 is connected to the cleaning arc block 250. During use, when the driven slide 251 slides along the groove outside the wire rope, the driven slide 251 deflects along the twisted groove, and the deflection of the driven slide 251 drives the connected cleaning arc block 250 and the telescopic link 253 to deflect synchronously.

[0062] Reference Figures 4 to 8 As shown, there are several arc-shaped plates 26 for sliding limit in the shell 20, and the laser emitting end 22 is limitedly connected to the arc-shaped plate 26, and the laser emitting end 22 is provided with several arc-shaped plates 26 corresponding to the laser emitting end 22, one of which is close to the driven slide rod 251 and is commonly connected to the driven slide rod 251 by a driven lever 260, and the two adjacent arc-shaped plates 26 are connected by a connecting rod 261.

[0063] During use, after the driven slide 251 deflects along the groove on the wire rope, it drives the connected driven slide 251 to deflect synchronously, and the driven slide 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 corresponding connected arc plates 26 to rotate synchronously through a number 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 wire rope to be measured, so that the several laser emitting ends 22 and the laser receiving end 23 on the two corresponding arc plates 26 rotate circumferentially relative to the wire rope, so as to complete the effect of measuring the nominal diameter of the wire rope.

[0064] 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 is sleeved on the driven slide rod 251 and located between the limit slider 27 and the guide sleeve 270.

[0065] 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 always tends to drive the connected limit slider 27 and the driven slide 251 to slide toward the middle of the wire rope, so that the driven slide 251 always sticks to the groove during the sliding process along the groove on the wire rope, preventing the driven slide 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 251 during the sliding process to a certain extent.

[0066] 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 avoid the connecting guide plate 25 limited on the mounting ring plate 200 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 for sliding limit in the sliding frame 272. 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.

[0067] In addition, the present invention also provides a wire rope infrared laser diameter detection method, comprising the following steps:

[0068] 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 placed on the outside of the steel wire rope to form a clamping state. After installing the ring plate 200 to assemble the housing 20, the limiting roller 21 is placed 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.

[0069] S2: During the measurement process, the laser emitting end 22 emits an infrared laser, the laser beam is irradiated on the surface of the wire rope and reflected, and the laser receiving end 23 receives the reflected beam. The diameter of the wire rope is calculated based on the geometric relationship between the laser emitting end 22, the wire rope and the laser receiving end 23.

[0070] S3: Drive the measuring component 2 and the wire rope to perform relative sliding motion to ensure that the laser beam can scan the entire circumference of the wire rope and achieve comprehensive measurement of the wire rope diameter.

[0071] It will be apparent 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 characteristics of the present invention. Therefore, the embodiments should be considered in all respects as exemplary and non-restrictive.

[0072] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method 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 can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
