Description
Technical Field
[0001] This invention relates to the field of wire rope inspection technology, and in particular to a visual inspection device for the condition of high-speed hoisting wire ropes in deep wells. Background Technology
[0002] The coal industry is a vital basic industry related to my country's economic lifeline and energy security, supporting the rapid growth of my country's national economy. As a key large-scale electromechanical equipment in coal mining and production, the mine hoisting system is mainly used to vertically transport underground personnel, coal raw materials, and important tools for coal production. Its hoisting capacity and operating performance determine the coal mine's production capacity.
[0003] During the use of hoisting wire ropes, damage caused by abnormal friction, scratching, collision, impact, compression, bending fatigue, etc., mostly acts directly on the surface of the wire rope and causes changes in its diameter. Local wire breakage or wear can change the mass distribution of the wire rope, causing unbalanced vibration. Vibration causes the wires inside the wire rope to be subjected to alternating stress, accelerating the propagation of fatigue cracks, which can easily cause safety hazards in production. Therefore, it is necessary to detect the vibration of the wire rope during hoisting.
[0004] In existing technologies, visual detection methods using cameras can be employed to determine the motion of objects. Among these methods, detecting the amplitude of vibration is a crucial aspect. However, when a camera captures the vibration of a steel wire rope, the high frequency of vibration during operation, coupled with the high cost of professional industrial cameras and the excessively long exposure time of ordinary cameras, results in blurred images due to the steel wire rope being imaged at multiple locations during the exposure period. This blurring severely compromises the clarity of feature points, affecting subsequent judgment of image data and consequently impacting the accuracy of the steel wire rope vibration detection. Summary of the Invention
[0005] The purpose of this invention is to provide a visual inspection device for the condition of high-speed hoisting steel wire ropes in deep wells. During the shooting process, the second rack remains stationary, avoiding image blurring caused by the rapid vibration frequency of the steel wire rope during operation. This prevents the subsequent judgment of image data from being affected, thereby preventing the impact on the detection accuracy of the steel wire rope vibration amplitude and solving the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a visual inspection device for the condition of a high-speed hoisting steel wire rope in a deep well, comprising a hoisting platform, a guide wheel rotatably mounted on the top right side of the hoisting platform for controlling the hoisting direction, and a winding wheel disposed on the left side of the hoisting platform, the surface of which is wound and fixed with a steel wire rope, characterized in that the visual inspection device for the condition of the steel wire rope further includes:
[0007] The detection component is located on the right side of the lifting platform. The detection component is used to detect the vibration amplitude of the wire rope.

A second rack that moves up and down is slidably connected inside the detection frame. The camera captures the height of the second rack to determine the vibration amplitude of the wire rope. The transmission component is located inside the detection frame. When the moving rod moves, the transmission component controls the lifting and lowering of the second rack. A limiting component is configured at the bottom and below the detection frame. When the second rack moves, the limiting component limits the movement of the second rack.
[0008] Preferably, the end of the moving rod is rotatably connected to a ball to reduce friction, and the outer wall of the moving rod is slidably connected to the detection frame. When the wire rope vibrates, the wire rope will squeeze the ball and the moving rod.

[0010] Preferably, the bottom of the bending frame is located above the lifting frame, and the bending frame is made of a high-density material.
[0011] Preferably, the transmission assembly includes a first rack fixedly connected to the side of the push plate away from the moving rod, and the transmission assembly also includes a rotating shaft rotatably connected inside the detection frame.

[0012] Preferably, a torsion spring is fixedly connected between the end of the rotating shaft and the detection frame.
[0013] Preferably, the diameter of the first gear is smaller than the diameter of the second gear.
[0014] Preferably, the outside of the detection frame is equipped with a spray assembly, which includes a connecting pipe fixedly inserted between the right side of the detection frame and the lifting frame.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0022] Example 1: Please refer to Figures 1 to 10 This invention provides a technical solution: a visual inspection device for the condition of a high-speed hoisting wire rope in a deep well, comprising a hoisting platform 1, a guide wheel 2 for controlling the hoisting direction rotatably on the top right side of the hoisting platform 1, and a winding wheel 3 arranged on the left side of the hoisting platform 1. A wire rope is wound and fixed on the surface of the winding wheel 3. When the wire rope is hoisted, the winding wheel 3 is driven to rotate by an external motor device, which can cause the winding wheel 3 to rotate to wind and unwind the wire rope, thereby hoisting it. The guide wheel 2 can adjust the direction of the wire rope to ensure vertical hoisting.
[0023] The wire rope condition visual inspection device also includes a detection component 4 disposed on the right side of the lifting platform 1. The detection component 4 is used to detect the vibration amplitude of the wire rope. The detection component 4 includes a mounting frame 41 fixed on the inner side of the right side of the lifting platform 1. A camera 42 is fixedly connected to the outer wall of the mounting frame 41. A fixing ring 43 is fixedly connected to the side of the mounting frame 41 away from the lifting platform 1. A detection frame 44 is fixedly arranged in a ring array on the top of the fixing ring 43. A push plate 45 is movable inside the detection frame 44. A moving rod 46 is fixedly connected to the side of the push plate 45 near the wire rope. A second rack 47 that moves up and down is slidably connected inside the detection frame 44. The camera 42 captures the height of the second rack 47 to determine the vibration amplitude of the wire rope.
[0024] The wire rope condition visual inspection device also includes a limiting component 6 disposed at the bottom and below the inspection frame 44. When the second rack 47 moves, the limiting component 6 limits the second rack 47. The end of the moving rod 46 is rotatably connected to a ball 48 for reducing friction. The outer wall of the moving rod 46 is slidably connected to the inspection frame 44. When the wire rope vibrates, the wire rope will squeeze the ball 48 and the moving rod 46.
[0025] The wire rope condition visual inspection device also includes a transmission component 5 disposed inside the inspection frame 44, which controls the lifting and lowering of the second rack 47 when the moving rod 46 moves.
[0026] The limiting component 6 includes a curved frame 61 slidably connected to the bottom of the detection frame 44. The bottom of the detection frame 44 is rotatably connected to a limiting plate 62 above the curved frame 61. The limiting component 6 also includes an electric telescopic rod 63 fixedly connected to the inner side of the bottom of the mounting frame 41. The output shaft of the electric telescopic rod 63 is fixedly connected to a lifting frame 64. A blocking strip 65 is fixedly connected to the side of the second rack 47 near the limiting plate 62 in a linear array. The bottom of the curved frame 61 is located above the lifting frame 64. The curved frame 61 is made of a high-density material.
[0027] The transmission assembly 5 includes a first rack 51 fixedly connected to the side of the push plate 45 away from the moving rod 46. The transmission assembly 5 also includes a rotating shaft 52 rotatably connected inside the detection frame 44. A torsion spring 55 is fixedly connected between the end of the rotating shaft 52 and the detection frame 44.
[0028] By adopting the above technical solution, when detecting the vibration of the wire rope, the wire rope is wound and unwound normally by rotating the winding wheel 3. When the wire rope vibrates, the position of the wire rope near the detection component 4 will vibrate. Under the action of vibration, the wire rope will squeeze the ball 48 and the moving rod 46, which can cause the ball 48 and the moving rod 46 to be squeezed and move away from the wire rope. This can cause the push plate 45 to move accordingly. Under the action of the transmission component 5, the second rack 47 can move upward.
[0029] When the second rack 47 moves upward, the blocking strip 65 fixed on its outer wall moves upward as well. When the blocking strip 65 approaches the limiting plate 62, since the limiting plate 62 is in a rotating state, the limiting plate 62 can squeeze through it. After one of the blocking strips 65 passes through the limiting plate 62, the limiting plate 62 will return to its original position under the action of gravity, and its bottom will contact the top of the bending frame 61, so that the limiting plate 62 can be in a horizontal state.
[0030] When the wire rope reaches its maximum vibration amplitude in a single vibration and is about to move back, the ball 48 and the moving rod 46 tend to return to their original position under the elastic force of the torsion spring 55. At this time, due to the blocking effect of the bending frame 61, the limiting plate 62 cannot move downward and deflect. The limiting plate 62 will block and limit the blocking bar 65, so that the second rack 47 cannot return to its original position. The top position of the second rack 47 remains at the maximum height caused by the maximum amplitude.
[0031] The height of the second rack 47 is periodically photographed by camera 42. The light signal is then converted into a digital signal, and features are extracted using image processing algorithms. Finally, the target state is determined by classification models or rules. At this time, the second rack 47 remains stationary due to the limiting plate 62 limiting the blocking bar 65. This prevents the image from becoming blurry due to the rapid vibration frequency of the wire rope during operation, thus preventing it from affecting the subsequent judgment of the image data and the accuracy of detecting the vibration amplitude of the wire rope.
[0032] After the shooting is completed, the output shaft of the electric telescopic rod 63 retracts immediately, which allows the lifting frame 64 to move downward. At this time, under the gravity of the bending frame 61, the bending frame 61 can move downward. At this time, the limiting plate 62 can deflect downward. Under the elastic force of the torsion spring 55, the ball 48 and the moving rod 46 move towards the steel wire rope to reset, which is convenient for the next shooting test. Then, the output shaft of the electric telescopic rod 63 extends.
[0033] It should be noted that if the vibration amplitude of the wire rope is greater than the previous vibration amplitude within a shooting and detection cycle, the limiting plate 62 can be deflected upward, allowing the ball 48 and the moving rod 46 to continue moving away from the wire rope.
[0034] It should be noted that the bottom of the detection frame 44 is provided with a slide rail to facilitate the up and down sliding of the bending frame 61, and the up and down sliding range of the bending frame 61 is limited.
[0035] It should be noted that multiple moving rods 46 are arranged around the wire rope to detect the vibration amplitude of the wire rope in different directions.
[0036] A first gear 53 is fixedly connected to the outer wall of the rotating shaft 52 near the first rack 51. The outer side of the first gear 53 meshes with the first rack 51. A second gear 54 is fixedly connected to the outer wall of the rotating shaft 52 near the second rack 47. The outer side of the second gear 54 meshes with the second rack 47. The diameter of the first gear 53 is smaller than the diameter of the second gear 54.
[0037] By adopting the above technical solution, when the ball 48 and the moving rod 46 are vibrated and squeezed by the wire rope and move away from the wire rope, the push plate 45 can move the first rack 51. Under the action of the first gear 53 meshing with the first rack 51, the first rack 51 can rotate with the rotating shaft 52 overcoming the elastic force of the torsion spring 55. At this time, the second gear 54 rotates accordingly. Under the action of the second gear 54 meshing with the second rack 47, the second rack 47 can move upward, thereby realizing the change in position of the second rack 47. Therefore, the vibration amplitude can be judged by taking pictures of the second rack 47 by the camera 42.
[0038] Since the diameter of the first gear 53 is smaller than the diameter of the second gear 54, and since both the first gear 53 and the second gear 54 are fixed to the rotating shaft 52, the second gear 54 rotates once for every one revolution of the first gear 53. This allows the second rack 47 to move a large amplitude when the movement amplitude of the moving rod 46 is small. This amplifies the displacement caused by the vibration amplitude, improves the accuracy of the image capture, and thus improves the accuracy of the visual inspection.
[0039] The detection frame 44 is externally equipped with a blower assembly 7. The end of the detection frame 44 away from the wire rope has a slot. The blower assembly 7 includes a connecting pipe 71 fixedly inserted between the right side of the detection frame 44 and the lifting frame 64. The blower assembly 7 also includes a blower frame 72 slidably connected to the inside of the mounting bracket 41. The inner side of the blower frame 72 has a linear array of spray holes 74. A ventilation pipe 73 is fixedly inserted between the blower frame 72 and the lifting frame 64. One section of the connecting pipe 71 is made of flexible material so as not to affect the up and down movement of the lifting frame 64. The ventilation pipe 73 is made of rigid material so that the lifting frame 64 and the blower frame 72 move up and down synchronously. During detection, the blower frame 72 is positioned above the lens of the camera 42 so that the blower frame 72 does not obstruct the lens of the camera 42 during detection.
[0040] By adopting the above technical solution, after the shooting is completed, the output shaft of the electric telescopic rod 63 retracts. At this time, under the elastic force of the torsion spring 55, the rotating shaft 52 rotates and resets, which facilitates the second rack 47 and the first rack 51 to move and reset, thereby resetting the moving rod 46. Since the moving rod 46 and the push plate 45 move towards the wire rope at this time, the air entering the detection frame 44 can enter the connecting pipe 71, thereby allowing the air to enter the lifting frame 64. Subsequently, the air enters the blow-blowing frame 72 through the ventilation pipe 73 and is sprayed out from the spray hole 74 to blow-blow and clean the lens of the camera 42, preventing impurities from adhering to the lens and affecting the accuracy of visual detection.
[0041] It should be noted that during the cleaning process, the output shaft of the electric telescopic rod 63 retracts, and the lifting frame 64 and the ventilation pipe 73 move downward with the blowing frame 72. During this movement, the blowing frame 72 passes through the lens of the camera 42, which allows air to be sprayed out at different positions to clean the lens, thereby improving the cleaning effect and further preventing impurities from adhering to the lens and affecting the accuracy of visual inspection.
[0042] It should be noted that when the blower frame 72 moves downward to the top of the lens, the limiting plate 62 can no longer limit the blocking strip 65. At this time, air begins to be ejected from the nozzle 74. Since there are many detection frames 44, there is enough air for air jetting to ensure the cleaning effect. The speed at which the output shaft of the electric telescopic rod 63 retracts is matched with the time required for the air to be completely ejected, ensuring the cleaning effect on the lens.
[0043] Working principle: When detecting the vibration of the wire rope, the take-up reel 3 rotates to wind and unwind the wire rope normally. When the wire rope vibrates, the area near the detection component 4 will vibrate. Under the action of vibration, the wire rope will compress the ball 48 and the moving rod 46, causing them to move away from the wire rope. This causes the push plate 45 to move accordingly. Under the action of the transmission component 5, the second rack 47 can move upward. Under the elastic force of the torsion spring 55, the ball 48 and the moving rod 46 tend to return to their original position. At this time, due to the blocking effect of the bending frame 61, the limiting plate 62 cannot move downward and deflect. At this time, the limiting plate 62 will block and limit the blocking bar 65, so that the second rack 47 cannot return to its original position. The top position of the second rack 47 maintains the maximum height caused by the maximum amplitude. When taking pictures at this time, the second rack 47 is in a stationary state to prevent the second rack 47 from being in a moving state and causing the picture to be blurry.
[0044] After the shooting is completed, the output shaft of the electric telescopic rod 63 retracts immediately, which allows the lifting frame 64 to move downward. At this time, under the gravity of the bending frame 61, the bending frame 61 can move downward. At this time, the limiting plate 62 can deflect downward. Under the elastic force of the torsion spring 55, the ball 48 and the moving rod 46 move towards the steel wire rope to reset, which is convenient for the next shooting test. Then, the output shaft of the electric telescopic rod 63 extends.
[0045] Since the diameter of the first gear 53 is smaller than the diameter of the second gear 54, and since both the first gear 53 and the second gear 54 are fixed to the rotating shaft 52, the second gear 54 rotates once for every one revolution of the first gear 53. This allows the second rack 47 to move a large amplitude when the movement amplitude of the moving rod 46 is small. This amplifies the displacement caused by the vibration amplitude, improves the accuracy of the image capture, and thus improves the accuracy of the visual inspection.
[0046] After the shooting is completed, the output shaft of the electric telescopic rod 63 retracts. At this time, under the elastic force of the torsion spring 55, the rotating shaft 52 rotates and resets, which facilitates the repositioning of the second rack 47 and the first rack 51, thereby resetting the moving rod 46. Since the moving rod 46 and the push plate 45 move towards the wire rope at this time, the air entering the detection frame 44 can enter the connecting pipe 71, thereby allowing the air to enter the lifting frame 64. Subsequently, the air enters the blow-blowing frame 72 through the ventilation pipe 73 and is sprayed out from the spray hole 74 to clean the lens of the camera 42, preventing impurities from adhering to the lens and affecting the accuracy of visual inspection. During the cleaning process, the output shaft of the electric telescopic rod 63 retracts, and the lifting frame 64 and the ventilation pipe 73 move downward with the blow-blowing frame 72. During this movement, the blow-blowing frame 72 passes through the lens of the camera 42, allowing air to be sprayed out at different positions to clean the lens, improving the cleaning effect and further preventing impurities from adhering to the lens and affecting the accuracy of visual inspection.
