Description

Technical Field

[0001] The invention relates to the technical field of wire rope detection equipment, and in particular to a follow-up optical and magnetic detection device and a detection method for a mine winding hoisting wire rope. Background Art

[0002] In actual use, wire ropes are easily affected by factors such as abnormal friction, scratches, collisions, impacts, extrusion and fatigue, which cause the surface to begin to be damaged, gradually expand and deteriorate, and may further cause wire breakage, wear, rust and even breakage. These damages may lead to serious safety problems, such as casualties caused by wire rope breakage. Therefore, it is crucial to study reliable and efficient non-destructive testing and evaluation methods for wire ropes. At present, the non-destructive testing technology of wire ropes has developed slowly, mainly relying on manual inspection under low-speed operating conditions, but this has problems such as high false / missed detection rate and insufficient real-time performance. Therefore, it is necessary to monitor the health of wire ropes in real time through innovative technologies.

[0003] In the related technology, the invention patent with application number CN202210779183.6 discloses a non-destructive testing device and a wire rope testing method, including a driving component, a detection component and a clamping component, wherein the clamping component is used to clamp and fix the wire rope, and the detection component is used for visual and magnetic leakage detection of the wire rope.

[0004] When the detection device in the above-mentioned related technology is used to detect the wire rope of the winding hoist, since the movement of the wire rope is mainly along the lifting direction and swinging perpendicular to the lifting direction when the winding hoist lifts heavy objects, these two movements constitute the spatial movement of the wire rope. Therefore, when detecting the wire rope, the wire rope will be offset due to the force, and the wire rope will be deformed due to the force of the clamping component on the wire rope, and the wire rope will have a position deviation from the detection point of the detection component, which will affect the detection effect. The spatial movement of the wire rope makes the detection more difficult. Summary of the invention

[0005] The object of the present invention is to provide a follow-up optical and magnetic detection device and detection method for mine winding and hoisting wire ropes. The optical and magnetic detection mechanism for detecting the wire ropes can move synchronously with the wire ropes, thereby improving the detection accuracy of the wire ropes.

[0006] In order to achieve the above-mentioned invention objectives, the technical solution adopted by the present invention is specifically: a follow-up optical and magnetic detection device for mine winding and hoisting wire rope, including a workbench, a support frame is arranged on the workbench, two first slide rails are arranged side by side on the support frame, and sliding support blocks are slidably arranged on the two first slide rails. A plurality of sliding rods are arranged between the two sliding support blocks. The plurality of sliding rods are arranged in parallel, and the axes of the sliding rods are arranged perpendicular to the long sides of the first slide rails. A follow-up platform is slidably arranged on the sliding rods, and an optical and magnetic detection mechanism for detecting the wire rope and an anti-bias clamping mechanism for rolling clamping of the wire rope are arranged on the follow-up platform. An excitation mechanism for exciting the wire rope is arranged on the support frame.

[0007] When the present invention is actually used: the steel wire rope to be tested is rollingly clamped by the anti-bias clamping mechanism, the excitation mechanism is used to excite the steel wire rope to be tested, and the optical magnetic detection mechanism can detect the quality of the steel wire rope. When the axial position of the steel wire rope changes during the detection process, the optical magnetic detection mechanism and the anti-bias clamping mechanism will move synchronously with the steel wire rope, making it difficult for the steel wire rope to deviate from the detection position of the optical magnetic detection mechanism, thereby improving the detection accuracy of the steel wire rope.

[0008] Furthermore, a plurality of lifting drive members are arranged on the workbench, and the lifting output shafts of the lifting drive members are arranged vertically, and the lifting output shafts of the plurality of lifting drive members are hingedly connected to the support frame.

[0009] By adopting the above technical solution, multiple lifting drive components cooperate with each other to adjust the angle of the support frame, which can be suitable for the detection of wire ropes at different angles.

[0010] Furthermore, the anti-skew clamping mechanism includes two first anti-skew wheels and two second anti-skew wheels, the two first anti-skew wheels are rotatably connected to the top of the photomagnetic detection mechanism, the two first anti-skew wheels are symmetrically arranged, and the two first anti-skew wheels are used for rolling clamping of the wire rope, the two second anti-skew wheels are rotatably connected to the bottom of the photomagnetic detection mechanism, the axis of the first anti-skew wheel and the axis of the second anti-skew wheel are vertically arranged, the two second anti-skew wheels are symmetrically arranged, and the two second anti-skew wheels are used for rolling clamping of the wire rope.

[0011] By adopting the above technical solution, the two first anti-skew wheels and the two second anti-skew wheels clamp the wire rope together, and the first anti-skew wheels and the second anti-skew wheels have different clamping angles, which can improve the stability of the wire rope clamping. In addition, since the first anti-skew wheel and the second anti-skew wheel are located on the upper and lower sides of the optical magnetic detection mechanism, the angle of the wire rope located in the detection area of ​​the optical magnetic detection mechanism can be guaranteed, and the accuracy of the wire rope detection result can be guaranteed.

[0012] Furthermore, the optical magnetic detection mechanism includes an electromagnetic platform connecting frame, an electromagnetic detection module, a plurality of industrial cameras and a plurality of lighting lamps. The electromagnetic platform connecting frame is connected to the follower platform, the electromagnetic detection module is arranged on the electromagnetic platform connecting frame, the plurality of industrial cameras and the plurality of lighting lamps are arranged on the electromagnetic platform connecting frame, the industrial cameras and the lighting lamps are staggered, and the plurality of industrial cameras are arranged in a circular array.

[0013] By adopting the above technical solution, the industrial camera is used to collect image data of the wire rope. The above arrangement can improve the collection accuracy of the collected image data and facilitate the determination of the damaged position of the wire rope.

[0014] Furthermore, the detection ring of the electromagnetic detection module includes a plurality of Hall sensors, and the plurality of Hall sensors are arranged in a circular array.

[0015] By adopting the above technical solution, the Hall sensor can collect the electromagnetic signal of the wire rope, and the damage position inside the wire rope can be analyzed according to the collected electromagnetic signal.

[0016] Furthermore, two second slide rails are arranged side by side on the support frame, a plurality of sliders are slidably arranged on the two second slide rails, a guide rod is arranged between the sliders on different second slide rails, a sliding support platform is slidably arranged on the guide rod, the excitation mechanism is arranged on the sliding support platform, and an encoding mechanism is arranged on the sliding support platform.

[0017] By adopting the above technical solution, the sliding support platform can slide along the axial direction of the guide rod and the slide direction of the second slide rail. During the detection of the wire rope, the excitation mechanism can slide along the wire rope, thereby ensuring the excitation effect on the wire rope.

[0018] Furthermore, the encoding mechanism includes a sliding mounting frame, a slide rail frame, a driving motor, a transmission screw, a sliding platform, an encoding connecting frame, an encoder, a counting wheel, a plurality of shock absorbers and two guide wheels. The sliding mounting frame is connected to the sliding support platform, the slide rail frame is arranged on the sliding mounting frame, the driving motor is arranged on the sliding mounting frame, the transmission screw is coaxially fixed on the output shaft of the driving motor, the sliding platform is slidingly arranged on the slide rail frame, the transmission screw is threadedly passed through the sliding platform, the encoding connecting frame is connected to the sliding platform, the two ends of the plurality of shock absorbers are respectively connected to the sliding platform and the encoding connecting frame, the encoder is arranged on the encoding connecting frame, the counting wheel is coaxially fixed on the output shaft of the encoder, the counting wheel is used to frictionally contact with the wire rope to be detected, the two guide wheels are rotatably arranged on the sliding mounting frame, and the two guide wheels are used to rollingly clamp the wire rope.

[0019] By adopting the above technical solution, in the process of testing the wire rope, the two guide wheels clamp and position the wire rope to be tested, the wire rope and the counting wheel are in friction contact, and when the wire rope moves, it will drive the counting wheel to rotate synchronously, and the encoder will convert the rotation signal of the counting wheel into a pulse signal output, thereby recording the moving distance of the wire rope. Since the encoding mechanism is on the sliding mounting frame, the encoding mechanism can also move with the wire rope, which can improve the coordination effect between the wire rope and the encoding mechanism.

[0020] Furthermore, the encoding connecting frame and the sliding platform are connected by a pin shaft, the plurality of shock absorbers are distributed on both sides of the pin shaft, the shock absorber and the encoding connecting frame are hingedly connected, and the hinge axis between the shock absorber and the encoding connecting frame is parallel to the pin shaft.

[0021] By adopting the above technical solution, when the steel wire rope vibrates or deviates on the hoist, the shock absorber can absorb the vibration, so that the steel wire rope can maintain good contact with the counting wheel.

[0022] Furthermore, the guide rod and the horizontal plane are arranged inclined.

[0023] By adopting the above technical solution, since the guide rod is inclined, when the counting wheel contacts the wire rope, the encoding mechanism as a whole has a downward tendency under the action of its own gravity. This force will be applied to the wire rope through the counting wheel, which can increase the contact friction between the wire rope and the counting wheel, making it less likely for the wire rope to slip when in contact with the counting wheel.

[0024] In order to better achieve the above-mentioned invention object, the present invention also provides a detection method of a mine winding hoisting wire rope follow-up optical magnetic detection device, comprising the following steps:

[0028] S3. The excitation mechanism excites the wire rope, the industrial camera and the Hall sensor respectively collect the image data and electromagnetic data of the wire rope to be detected, and the encoding mechanism converts the movement data of the wire rope into counting pulses to record the detection position of the wire rope.

[0029] S4. When the axial position of the wire rope changes during the detection process, the wire rope drives the follow-up platform and the sliding support platform to move synchronously.

[0030] S5. The staff analyzes the collected electromagnetic data and image data to determine whether the wire rope can be used normally, and determines the damaged location of the wire rope based on the counting pulses.

[0031] By adopting the above technical solution, the detection accuracy of the wire rope can be improved.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

The sliding rod can slide on the first slide rail through a sliding support block, and the follow-up platform can slide on the sliding rod. The optical magnetic detection mechanism for detecting the wire rope and the anti-bias clamping mechanism for clamping the wire rope on the follow-up platform can slide on the plane formed by the first slide rail and the sliding rod. During the detection process, when the wire rope deviates, the optical magnetic detection mechanism and the anti-bias clamping mechanism will move synchronously with the wire rope, so that the wire rope is not easy to deviate from the detection position of the optical magnetic detection mechanism, which can improve the detection accuracy of the wire rope.

[0034] 2. The present invention can drive the inclination angle of the follower platform by setting a plurality of lifting drive parts, so that the follower platform can remain perpendicular to the steel wire ropes at different angles, can be suitable for the detection of different steel wire ropes, and improves the scope of application.

[0035] 3. The present invention detects the appearance of the steel wire rope through an industrial camera and can detect the internal structure of the steel wire rope through a Hall sensor. Under the joint action of the industrial camera and the Hall sensor, the staff can evaluate the overall quality of the steel wire rope.

[0036] 4. The present invention sets up a coding mechanism. During the process of detecting the wire rope, the wire rope and the counting wheel are in friction contact. When the wire rope moves, it will drive the counting wheel to rotate synchronously. The encoder will convert the rotation signal of the counting wheel into a pulse signal output, thereby recording the moving distance of the wire rope, which is convenient for determining the damaged position of the wire rope.

DETAILED DESCRIPTION

[0046] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. Of course, the specific embodiments described here are only used to explain the present invention and are not used to limit the present invention.

[0047] Example:

[0048] Reference Figure 1A follow-up optical magnetic detection device for winding and hoisting wire ropes in a mine includes a workbench 1, the top surface of the workbench 1 is inclined to the horizontal plane, and four lifting drive members 2 are detachably mounted on the top surface of the workbench 1 by bolts, and the four lifting drive members 2 are arranged in a rectangular array. In this embodiment, the lifting drive members 2 are electric cylinders 21. The electric cylinders 21 are arranged in groups of two, and the electric cylinders 21 in the same group are at the same height. The output shaft of the electric cylinder 21 is vertically arranged, and the top end of the output shaft of the electric cylinder 21 is connected to a support frame 3, and the output shafts of the four electric cylinders 21 are hingedly connected to the support frame 3.

[0049] Reference Figures 1 to 4 Two first slide rails 4 are installed side by side on the top of the support frame 3 by bolts, and sliding support blocks 5 are slidably arranged on the two first slide rails 4. Two sliding rods 6 are fixedly connected between the two sliding support blocks 5. The two sliding rods 6 are arranged in parallel, and the axes of the sliding rods 6 are arranged perpendicular to the long sides of the first slide rails 4. A follow-up platform 7 is slidably arranged on the sliding rods 6, and the follow-up platform 7 is provided with an optical magnetic detection mechanism 8 for detecting the wire rope and an anti-bias clamping mechanism 9 for rolling clamping of the wire rope.

[0050] Reference Figures 1 to 4 Two second slide rails 10 are installed side by side by bolts at the lower position of the support frame 3. The second slide rails 10 are arranged in parallel with the first slide rail 4. Two sliders 11 are slidably installed on the two second slide rails 10. A guide rod 12 is fixed between the sliders 11 on different second slide rails 10. The guide rod 12 and the slide rod 6 are arranged in parallel. A sliding support table 13 is also installed on the two guide rods 12. An excitation mechanism 14 for excitation of the wire rope is installed at the lower position of the sliding support table 13. In this embodiment, the excitation mechanism 14 is mainly composed of a permanent magnet. An encoding mechanism 15 for recording the position of the wire rope is installed at the upper position of the sliding support table 13.

[0051] When testing the wire rope, the wire rope passes through the excitation mechanism 14 and is rollingly clamped by the anti-bias clamping mechanism 9. The photomagnetic detection mechanism 8 can detect the quality of the wire rope. When the axial position of the wire rope changes during the detection process, the photomagnetic detection mechanism 8 and the anti-bias clamping mechanism 9 will move synchronously with the wire rope, making it difficult for the wire rope to deviate from the detection position of the photomagnetic detection mechanism 8, thereby improving the detection accuracy of the wire rope.

[0052] Reference Figure 1 and Figure 5The anti-skew clamping mechanism 9 includes two first anti-skew wheels 91 and two second anti-skew wheels 92. The two first anti-skew wheels 91 are rotatably connected to the upper part of the electromagnetic platform connecting frame 81 of the optical and magnetic detection mechanism 8. The two first anti-skew wheels 91 are symmetrically arranged. The two first anti-skew wheels 91 are used for rolling clamping of the wire rope. The two second anti-skew wheels 92 are rotatably connected to the lower part of the electromagnetic platform connecting frame 81 of the optical and magnetic detection mechanism 8. The axis of the first anti-skew wheel 91 and the axis of the second anti-skew wheel 92 are vertically arranged. The two second anti-skew wheels 92 are symmetrically arranged. The two second anti-skew wheels 92 are used for rolling clamping of the wire rope.

[0053] When the first anti-skew wheel 91 and the second anti-skew wheel 92 clamp the steel wire rope, the steel wire rope remains perpendicular to the first anti-skew wheel 91 and the second anti-skew wheel 92 respectively, so that the steel wire rope between the first anti-skew wheel 91 and the second anti-skew wheel 92 is not easy to deviate. Since the clamping angles of the first anti-skew wheel 91 and the second anti-skew wheel 92 are different, the stability of the steel wire rope clamping can be improved. Since the first anti-skew wheel 91 and the second anti-skew wheel 92 are arranged on the upper and lower sides of the optical magnetic detection mechanism 8, it can ensure that the steel wire rope located in the detection area of ​​the optical magnetic detection mechanism 8 is not easy to deviate, and the accuracy of the steel wire rope detection result can be ensured.

[0054] Reference Figure 5 and Figure 6 The optical magnetic detection mechanism 8 includes an electromagnetic platform connecting frame 81, an electromagnetic detection module 82, three industrial cameras 83 and five lighting lamps 84. The electromagnetic platform connecting frame 81 and the follower platform 7 are connected by bolts. The electromagnetic detection module 82 is installed on the electromagnetic platform connecting frame 81. In this embodiment, the electromagnetic detection module 82 includes eight Hall sensors and a detection circuit. The eight Hall sensors are evenly arranged on the detection ring of the electromagnetic detection module 82. When the anti-bias clamping mechanism 9 clamps the wire rope, the eight Hall sensors are arranged around the wire rope, and the Hall sensors can collect the electromagnetic signal of the wire rope. The detection circuit is electrically connected to the eight Hall sensors, and the detection circuit is used to transmit the signals collected by the Hall sensors to the computer for visual display.

[0055] Reference Figure 6, the middle position of the electromagnetic platform connecting frame 81 includes a symmetrically arranged single-camera integrated board 811 and a dual-camera integrated board 812, two industrial cameras 83 and three lighting lamps 84 are installed on the dual-camera integrated board 812, and the two industrial cameras 83 and three lighting lamps 84 on the dual-camera integrated board 812 are arranged in a staggered manner. An industrial camera 83 and two lighting lamps 84 are installed on the single-camera integrated board 811, and the industrial camera 83 and two lighting lamps 84 on the single-camera integrated board 811 are arranged in a staggered manner, and the three industrial cameras 83 are arranged in a circular array. When the anti-bias clamping mechanism 9 clamps the wire rope, the three industrial cameras 83 are arranged around the wire rope, and the three industrial cameras 83 shoot the outer surface of the wire rope at different angles without visual blind spots. Through the above-mentioned settings, the clarity of the image taken by the industrial camera 83 on the wire rope can be improved, which is convenient for determining the damage position on the outer surface of the wire rope.

[0056] Reference Figure 5 and Figure 7 The encoding mechanism 15 includes a sliding mounting frame 151, a slide rail frame 152, a driving motor 153, a transmission screw 154, a sliding platform 155, an encoding connecting frame 156, an encoder 157, a counting wheel 158, two shock absorbers 159 and two guide wheels 1510. The sliding mounting frame 151 is connected to the sliding support platform 13. The two guide wheels 1510 are rotatably mounted on the top of the sliding mounting frame 151. The two guide wheels 1510 are used to clamp and position the steel wire rope to be detected, so that the sliding mounting frame 151 and the steel wire rope to be detected can move synchronously. The two guide wheels 1510 are arranged close to the second anti-deviation wheel 92, and the axes of the guide wheels 1510 and the second anti-deviation wheel 92 are arranged vertically. Through this arrangement, the guide wheels 1510 and the second anti-deviation wheel 92 clamp the steel wire rope at different angles, which can reduce the possibility of the steel wire rope being offset during the detection process.

[0057] The slide rail frame 152 is mounted on the slide mounting frame 151, the drive motor 153 is mounted on the slide mounting frame 151, the transmission screw 154 is coaxially fixed on the output shaft of the drive motor 153, and the transmission screw 154 is mounted on the slide rail frame 152, the slide rail frame 152 supports the transmission screw 154, and the axis of the transmission screw 154 is parallel to the slideway direction of the second slide rail 10. The slide platform 155 is slidably arranged on the slide rail frame 152, the transmission screw 154 is threadedly arranged on the slide platform 155, the encoding connecting frame 156 is fixed to the top of the slide platform 155 through the pin 16, the two ends of the two shock absorbers 159 are respectively connected to the slide platform 155 and the encoding connecting frame 156, the top of the shock absorber 159 is hingedly connected to the encoding connecting frame 156, and the hinge axis of the shock absorber 159 and the encoding connecting frame 156 is parallel to the pin 16. Two vibration dampers 159 are distributed on both sides of the pin 16, so as to improve the vibration reduction effect. The encoder 157 is arranged on the encoding connecting frame 156, and the counting wheel 158 is coaxially fixed on the output shaft of the encoder 157, and the counting wheel 158 is used for friction contact with the steel wire rope to be detected. In this embodiment, the counting wheel 158 is made of polyurethane to improve the anti-slip performance. During the test process, the position of the counting wheel 158 can be adjusted by controlling the driving motor 153.

[0058] In this embodiment, the first slide rail 4 and the second slide rail 10 are made of chrome-plated 45 steel, which meets the strength requirements and the performance requirements of different building structures.

[0059] Reference Figure 4 In this embodiment, the guide rod 12 is always inclined to the horizontal plane. In a natural state, the encoding mechanism 15 has an overall downward tendency under the action of its own gravity. This force will be applied to the wire rope through the counting wheel 158, which can increase the contact friction between the wire rope and the counting wheel 158, making it less likely for the wire rope and the counting wheel 158 to slip when they contact.

[0060] In the process of detecting the steel wire rope, the steel wire rope and the counting wheel 158 are in frictional contact. When the steel wire rope moves, it will drive the counting wheel 158 to rotate synchronously. The encoder 157 will convert the rotation signal of the counting wheel 158 into a pulse signal output, thereby recording the moving distance of the steel wire rope. Since the encoding mechanism 15 is on the sliding mounting frame 151, the encoding mechanism 15 can also move with the steel wire rope, which can improve the coordination effect between the steel wire rope and the encoding mechanism 15.

[0061] Specifically, the encoder 157 mainly includes a photoelectric sensor and a coding disk. When the wire rope drives the counting wheel 158 to rotate, it will drive the coding disk to rotate synchronously. The photoelectric sensor will scan the lines or marks on the coding disk, thereby generating a digital pulse signal output, thereby recording the moving distance of the wire rope and providing original data for analyzing the angle changes of the wire rope at different positions.

[0062] Reference Figures 1 to 7 The present invention also provides a detection method of a mine winding hoisting wire rope follow-up optical and magnetic detection device, comprising the following steps:

[0063] S1. The steel wire rope to be tested is passed through the excitation mechanism 14, and the anti-bias clamping mechanism 9 rolls and clamps the steel wire rope to be tested.

[0064] S2. Control the lifting drive member 2 to adjust the angle of the follower platform 7 so that the follower platform 7 and the steel wire rope to be tested remain vertical.

[0065] S3, the excitation mechanism 14 excites the wire rope, the industrial camera 83 and the Hall sensor respectively collect the image data and electromagnetic data of the wire rope to be detected, and transmit the image data and electromagnetic data to the computer for visual display, and the encoding mechanism 15 converts the movement data of the wire rope into counting pulses to record the detection position of the wire rope.

[0066] S4. When the axial position of the steel wire rope changes during the detection process, the steel wire rope drives the follower platform 7 and the sliding support platform 13 to move synchronously.

[0067] S5. The staff analyzes the collected electromagnetic data and image data to determine whether the wire rope can be used normally, and determines the damage location of the wire rope by combining the counting pulses. The internal damage location of the wire rope can be obtained through electromagnetic data, and the external damage location can be analyzed through image data.

[0068] For image data, industrial camera 83 will collect images while dragging the wire rope. The collected data will be transmitted to the computer through the data cable. The computer will save the collected data in the hard disk, and then denoise the image to make the image have uniform lighting and clear texture. Pixel-level image fusion is used to improve the spatial resolution and clarity of the image, and it can provide as much richer and more accurate original detail information as possible that cannot be provided by other levels of fusion processing, making it easier for people to observe the image, and the fused image is more suitable for computer vision detection processing.

[0069] For electromagnetic data, when detecting the leakage magnetic signal, the original signal needs to be preprocessed. The preprocessing is to detrend the original signal and then interpolate the detrended signal to form an image. The purpose of the preprocessing is to improve image details and enhance image quality. Then the broken wire leakage magnetic signal is post-processed. The post-processing first reduces the noise of the strand wave signal through the line detection method, and then expands the leakage magnetic signal. Then the threshold binarization is used to complete the transformation of the electromagnetic image. The visual detection device and the electromagnetic detection device are used to detect the wire rope damage image for feature matching. The purpose is to construct a damage data set.

[0070] By fusing the image data with the rope damage image generated by electromagnetic data, the wire rope damage detection is more accurate; then the fused image is input and detected using the YOLOv5s algorithm; finally, the damage location is completed. When the wire rope is running, the position information of the wire rope is read through the differential coding method, and each position and the corresponding time are recorded, and the result is saved in a txt file; secondly, when detecting the video, the system will detect each frame of the image. If the target detection algorithm detects wire rope damage, the time of the damaged frame is obtained through the video calculation method; then the position corresponding to the moment is found in the txt file table according to the obtained time; finally, the position information is sent back to the main interface.

[0071] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
