Description

Technical Field

[0001] This invention belongs to the field of hoisting rope maintenance technology, and relates to an automatic detection system and method for hoisting ropes in vertical shafts. Background Technology

[0002] Steel wire rope hoists operating in coal mine shafts are prone to problems such as wire breakage, outer layer loosening and deformation, and internal rusting under long-term friction, water spray, and temperature changes. If hoisting and transportation are carried out under these conditions for a long time, it will pose a great threat to transportation safety and personal safety.

[0003] Currently, the inspection and maintenance of steel wire ropes in coal mine vertical shaft guideways are mainly carried out manually. However, due to limitations such as working environment and working conditions, it is impossible to guarantee a comprehensive inspection of the steel wire ropes. This poses significant safety hazards to the lives of employees and the safe production of coal mines. Furthermore, the inspection usually requires the cooperation of multiple people, which greatly wastes human resources.

[0004] During the maintenance and inspection of wire rope cages, the diameter measurement of the cage ropes is also an important aspect. Typically, workers on the top platform of the cage use vernier calipers to perform intermittent distance measurements of the cage ropes. However, performing rope diameter measurements in a vertical shaft is often unregulated and cumbersome, easily leading to inaccurate results. Furthermore, human factors, dim lighting, and space constraints can also cause inaccurate rope diameter measurement data.

[0005] Furthermore, the cage operates at a very high speed during hoisting and transportation, typically approaching 10 m / s. To ensure the safe operation of the cage, it is necessary to minimize the wear of the wire rope. Slip sleeves are installed on the outside of the cage, inside the cage lugs at the four corners, allowing for cage movement. However, the harsh environment inside the shaft often results in the lugs and slip sleeves being surrounded by coal slurry or debris. This makes wear inspection of the slip sleeves in the lugs extremely time-consuming and labor-intensive, and the inspection location is highly dangerous, posing a significant safety hazard. Summary of the Invention

[0006] To address the shortcomings of existing technologies, the present invention aims to provide an automatic detection system and method for hoisting guide ropes in vertical shafts. This system replaces the traditional manual sampling inspection of guide ropes with automatic real-time detection, improving detection efficiency and accuracy while saving labor intensity. It enables automatic detection of guide rope diameter and wear detection of guide sleeves, thereby enhancing the safety of work in vertical shafts and improving the quality of guide rope maintenance.

[0007] To achieve this objective, the present invention adopts the following technical solution:

[0008] In a first aspect, the present invention provides an automatic detection system for the hoisting guide rope of a vertical shaft, the automatic detection system comprising a central control module, a hoisting module and at least one detection module, wherein the central control module is wirelessly connected to the detection module;

[0009] The lifting module includes a lifting mechanism and at least one movable cage connected by a transmission. The lifting mechanism is used to drive the movable cage to slide along the cage guide rope. A cage ear is provided at the connection between the movable cage and the cage guide rope. The cage ear is slidably connected to the cage guide rope. A guide sleeve is provided inside the cage ear. The guide sleeve is sleeved on the outer periphery of the cage guide rope.

[0010] The detection module includes a sliding sleeve, a telescopic cantilever, and a housing. The sliding sleeve is fitted around the outer periphery of the guide rope. The two ends of the telescopic cantilever are movably connected to the sliding sleeve and the housing, respectively. The housing is fixed to the mobile cage. A rope diameter detection mechanism is provided inside the sliding sleeve for detecting the rope diameter of the guide rope. A wear detection mechanism is provided on the telescopic cantilever for detecting the wear of the guide sleeve.

[0011] This invention provides an automatic detection system for hoisting cage guide ropes in vertical shafts. Through a wireless connection between an intelligent detection module and a centralized control module, it achieves automatic fault detection of the guide ropes. It integrates a rope diameter detection mechanism and a wear detection mechanism to detect the rope diameter and wear of the guide sleeve of the moving cage during its movement. The real-time detection results are transmitted to the centralized control module wirelessly, reducing the number of personnel in the vertical shaft, lowering the safety risks of the detection work, and greatly improving the detection accuracy and efficiency.

[0012] In this invention, 4×N guide ropes are vertically fixed inside the shaft, where N is an integer greater than 1. A movable cage is slidably mounted between every four guide ropes. Each movable cage has a can-ear at one of its four suspended corners to achieve a sliding connection with the guide ropes. A guide sleeve is installed inside the can-ear and fitted onto the guide rope. As the movable cage slides, the guide sleeve wears. The total gap between the guide rope and the guide sleeve must not exceed 15mm. When the wear of the guide sleeve or the total gap between the guide rope and the guide sleeve reaches the following limits, it must be replaced. This invention uses a wear detection mechanism to monitor the wear of the guide sleeve on the movable cage in real time, enabling timely detection and replacement of faults to avoid safety issues.

[0013] This invention does not impose specific requirements or limitations on the structure of the lifting mechanism. To help those skilled in the art better understand the overall technical solution and working process of this invention, the present invention provides the following exemplary structure of the lifting mechanism:

[0014] The lifting mechanism includes a drum, a drive wheel, a conveyor belt, and a lifting rope. The conveyor belt connects the drum and the drive wheel. The rotation of the drum drives the drive wheel to rotate. The lifting rope is wound around the surface of the drive wheel. Each end of the lifting rope is connected to a mobile cage. As the drive wheel rotates, one mobile cage is lowered while the other mobile cage is raised.

[0015] It should be noted that the above description of the structure of the lifting mechanism does not constitute a further limitation on the scope of protection of this invention. That is, any lifting mechanism that has been disclosed in the prior art or not disclosed in the new technology can be used in this invention. It is not limited to the lifting mechanism with the above structure. As long as the lifting mechanism can achieve the same or similar function, it can be arbitrarily replaced. The technical solution obtained after replacement also falls within the scope of protection and disclosure of this invention.

[0016] As a preferred embodiment of the present invention, a rotating platform is provided on the top of the housing, and the end of the telescopic cantilever away from the sliding sleeve is rotatably connected to the rotating platform.

[0017] The telescopic cantilever rotates around the rotary table on the detection plane, which is a horizontal plane perpendicular to the direction of movement of the moving cage.

[0018] In this invention, the moving direction of the mobile cage is set as the Y-axis (i.e., the central axis of the rotary table), and the direction perpendicular to the moving direction of the mobile cage is set as the X-axis. The telescopic cantilever can translate on the X-axis, resulting in translational displacement. At the same time, it can rotate on the horizontal plane where the X-axis is located, about the center of the Y-axis, resulting in angular displacement.

[0019] Preferably, a control device is provided inside the housing, and the control device is electrically connected to the rope diameter detection mechanism, the wear detection mechanism and the central control module respectively.

[0020] The detection module in this invention encompasses functions such as data acquisition, data analysis, and data storage. The control device inside the housing is electrically connected to the rope diameter detection mechanism and the wear detection mechanism. Based on the data collected by the rope diameter detection mechanism and the wear detection mechanism, it performs data analysis and conversion, and transmits the data to the centralized control module. The centralized control module, based on the received information and various threshold parameter settings, performs analysis, judgment, and execution functions.

[0021] Preferably, a positioning mechanism is provided at the bottom of the sliding sleeve. The positioning mechanism is electrically connected to the control device. The positioning mechanism is used to determine the location of the fault point and transmit it to the control device, which then feeds it back to the centralized control module.

[0022] The present invention provides a positioning mechanism that can detect the specific position of the housing in the vertical shaft in real time and determine the fault location, thereby improving detection accuracy and facilitating subsequent maintenance.

[0023] Preferably, the box body is fixed to the mobile cage by a fixing bracket.

[0024] This invention features a fixed mounting bracket with a self-locking mechanism and a foot-operated unlocking mechanism, ensuring convenient installation and removal of the cabinet, saving time and effort. To prevent accidental unlocking of the cabinet's lifting plate, such as by personnel stepping on it or by falling objects, the lifting plate can only be unlocked and removed by a person stepping on it. The fixed mounting bracket's entry opening uses a chamfered ramp, making the cabinet's insertion very smooth and saving installation time.

[0025] As a preferred embodiment of the present invention, the wear detection mechanism includes a first displacement detection element and a second displacement detection element, which are disposed inside the rotary table.

[0026] The first displacement detection element is used to detect a first displacement, which is the linear translation of the telescopic cantilever on the detection plane.

[0027] The second displacement detection element is used to detect a second displacement, which is the angle of movement of the telescopic cantilever on the detection plane.

[0028] Preferably, the first displacement detection element and the second displacement detection element are electrically connected to the control device, and the first displacement detection element and the second displacement detection element respectively collect the first displacement amount and the second displacement amount and transmit them to the control device. The control device converts the first displacement amount and the second displacement amount into wear amount electrical signals and transmits them to the centralized control module.

[0029] In this invention, the first displacement detection element and the second displacement detection element are hidden inside the rotary table. The first displacement detection element collects the first displacement signal of the telescopic cantilever on the X-axis, mainly capturing the horizontal wear of the guide sleeve in the X-axis direction. The second displacement detection element collects the second displacement signal of the telescopic cantilever on the Y-axis, mainly capturing the wear of the guide sleeve in the Y-axis direction. The first and second displacement signals are transmitted to the control device. After processing by the program, the control device calculates the actual wear data of the guide sleeve and transmits it to the centralized control module. The centralized control module executes the corresponding function according to the received information.

[0030] This invention does not impose specific requirements or limitations on the first and second displacement detection components. Any detection component that can achieve the same or similar functions can be used in this invention, and the resulting technical solution will also fall within the protection and disclosure scope of this invention. For example, the first displacement detection component can be a linear displacement detection sensor horizontally mounted on the X-axis, and the second displacement detection component can be a rotational angle displacement detection sensor vertically mounted on the Y-axis, achieving 0–360° detection without blind spots.

[0031] As a preferred embodiment of the present invention, the rope diameter detection mechanism includes at least three third displacement detection elements arranged circumferentially along the inner wall of the sliding sleeve, the at least three third displacement detection elements forming a detection ring around the can guide rope.

[0032] Preferably, when the number of the third displacement detection elements is even, the third displacement detection elements are symmetrically arranged in pairs along the circumferential direction on the inner wall of the sliding sleeve.

[0033] Preferably, the third displacement detection element is provided with a detection wheel at one end near the guide rope, and the detection wheel abuts against the guide rope.

[0034] Preferably, the third displacement detection element is electrically connected to the control device. The third displacement detection element collects the change in rope diameter and transmits it to the control device. The control device analyzes and processes the change in rope diameter and transmits it to the centralized control module.

[0035] In this invention, after the sliding sleeve is fixed to the outer circumference of the guide rope, at least three third displacement detection elements are positioned precisely against the outer surface of the guide rope. Since the guide rope is a stationary track, during the detection process, the third displacement detection elements in the sliding sleeve form a rope diameter detection loop around the guide rope. This rope diameter detection loop moves parallel to the guide rope as the moving cage moves. During this movement, the third displacement detection elements detect the physical quantity of the rope diameter change and transmit it to the control device for data processing. The control device then wirelessly uploads the processed data electrical signal to the centralized control module.

[0036] In this invention, at least three third displacement detection elements are symmetrically arranged to perform normal wear detection, internal rust bulging detection, and external damage deformation detection of the guide rope diameter (￠45mm). After comparing the detected values ​​with the benchmark set values, the actual rope diameter is obtained.

[0037] As a preferred embodiment of the present invention, the sliding sleeve includes a first housing and a second housing, the first housing and the second housing having the same semi-cylindrical structure, and the axial edges of the first housing and the second housing being aligned and fastened together to form the sliding sleeve.

[0038] Preferably, one side of the first housing is hinged to one side of the second housing, and the other side of the first housing is snap-fitted to the other side of the second housing.

[0039] Preferably, a first positioning wheel is provided at the upper and lower ends of the first housing along the axial direction, and a second positioning wheel is provided at the upper and lower ends of the second housing along the axial direction. The first positioning wheel and the second positioning wheel abut against the guide rope for positioning.

[0040] Preferably, the first positioning wheel and the second positioning wheel are arranged symmetrically.

[0041] In this invention, the first shell and the second shell are respectively locked to the cage of the can guide rope, and four positioning wheels are symmetrically installed at the upper and lower ends to hold the can guide rope tightly. The four positioning wheels and the can guide rope form a tight rolling friction, so that the sliding sleeve and the can guide rope are integrated into one.

[0042] As a preferred embodiment of the present invention, the centralized control module includes an alarm mechanism and an emergency stop mechanism. The alarm mechanism and the emergency stop mechanism are independently and electrically connected to the control device inside the housing. The control device triggers the alarm mechanism to issue an alarm or triggers the emergency stop mechanism to shut down the lifting module based on the collected first displacement, second displacement and rope diameter change.

[0043] The control device in this invention processes the first displacement, the second displacement, and the change in rope diameter to obtain a data electrical signal, and uploads the data electrical signal to the centralized control module. The centralized control module analyzes the received data signal and controls the alarm mechanism to issue an alarm, or triggers the emergency stop mechanism to shut down the hoisting module.

[0044] As a preferred embodiment of the present invention, the guide sleeve includes a first sleeve and a second sleeve, the first sleeve and the second sleeve are identical semi-cylindrical structures, and the axial edges on both sides of the first sleeve and the second sleeve are aligned and fitted to form the guide sleeve.

[0045] Preferably, the difference between the diameter of the guide sleeve and the diameter of the guide rope is ≤5mm.

[0046] In this invention, the first and second sets of semi-cylindrical bodies are both embedded inside the ear of the movable cage. The guide rope passes through the internal space of the guide sleeve, and there is a 1mm sliding space between them. The sliding space is filled with high-viscosity lubricating oil, which can ensure effective lubrication between the guide rope and the guide sleeve and extend the service life of the guide rope. On the other hand, it can prevent water in the vertical shaft from seeping into the inside of the guide rope, thereby causing rust and corrosion inside the guide rope.

[0047] Secondly, the present invention provides an automatic detection method for vertical shaft hoisting guide ropes. The automatic detection method employs the automatic detection system for vertical shaft hoisting guide ropes described in the first aspect, and the automatic detection method includes:

[0048] The lifting mechanism drives the mobile cage to move along the guide rope. During the movement of the mobile cage, the wear detection mechanism detects the wear of the guide sleeve, and the rope diameter detection mechanism of the detection module detects the rope diameter of the guide rope. The rope diameter detection results and wear detection results are fed back to the central control module.

[0049] The automatic detection method for hoisting guide ropes provided by this invention replaces the traditional manual sampling inspection of guide ropes with automatic real-time detection, which improves detection efficiency and accuracy, while saving labor intensity and reducing work safety risks.

[0050] As a preferred embodiment of the present invention, the wear detection includes:

[0051] The first displacement detection element of the wear detection mechanism detects the linear translation of the telescopic cantilever on the detection plane to obtain the first displacement. The second displacement detection element detects the movement angle of the telescopic cantilever on the detection plane to obtain the second displacement. The detection module integrates and analyzes the first and second displacements, converts them into wear quantity electrical signals, and transmits them to the central control module.

[0052] The central control module analyzes the electrical signals and controls the alarm mechanism to issue an alarm, or triggers the emergency stop mechanism to shut down the lifting module.

[0053] As a preferred embodiment of the present invention, the rope diameter detection includes:

[0054] The rope diameter detection mechanism uses at least three third displacement detection elements to form a detection ring around the guide rope. The detection ring moves along the guide rope with the sliding sleeve, and collects the physical quantity of rope diameter change during the movement to obtain the rope diameter change amount, which is then transmitted to the central control module.

[0055] The rope diameter detection described in this invention includes normal wear detection, internal rust and bulging detection, and external damage and deformation detection. To help those skilled in the art better understand the overall technical solution and working process of this invention, the following specific working process for rope diameter detection is provided as an example:

[0056] After the sliding sleeve is closed and locked, the four adjusted third displacement detection elements abut against the outer surface of the closed guide rope, forming a detection ring around the guide rope. As the sliding sleeve moves along the guide rope, the physical quantity of the rope diameter change is collected during the movement and transmitted to the control device.

[0057] The control device has a pre-set reference value. The control device processes the received detection value and compares it with the reference value to obtain the actual rope diameter. It analyzes the detection results of whether the guide rope is normal wear, internal rust bulging, or external damage and deformation, and uploads them to the central control module. The central control module analyzes the electrical signal and controls the alarm mechanism to issue an alarm or triggers the emergency stop mechanism to shut down the hoisting module.

[0058] The system refers to an equipment system, device system, or production device.

[0059] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0060] This invention provides an automatic detection system and method for hoisting cage guide ropes in vertical shafts. It replaces traditional manual sampling inspections with automatic real-time detection. Through a wireless connection between an intelligent detection module and a centralized control module, it achieves automatic fault detection of the guide ropes. It integrates a rope diameter detection mechanism and a wear detection mechanism, enabling the detection of the rope diameter and the wear of the guide sleeve of the moving cage during its movement. This reduces the number of personnel required in the vertical shaft, lowers the safety risks of the inspection work, and greatly improves the accuracy and efficiency of the inspection.

Thus, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0065] It should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "set," "connected," and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0066] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0067] In one specific embodiment, the present invention provides an automatic detection system for the hoisting guide rope in a vertical shaft, such as... Figure 1 As shown, it includes a central control module, an enhancement module, and at least one detection module, wherein the central control module is wirelessly connected to the detection module;

[0068] The lifting module includes a lifting mechanism connected by a transmission and at least one movable cage 9. The lifting mechanism is used to drive the movable cage 9 to slide along the guide rope 10. A cage ear 11 is provided at the connection between the movable cage 9 and the guide rope 10. The cage ear 11 is slidably connected to the guide rope 10. A guide sleeve 12 is provided inside the cage ear 11. The guide sleeve 12 is sleeved on the outer periphery of the guide rope 10.

[0069] The detection module includes a sliding sleeve 3, a telescopic cantilever 2, and a housing 1. The sliding sleeve 3 is sleeved on the outer periphery of the guide rope 10. The two ends of the telescopic cantilever 2 are movably connected to the sliding sleeve 3 and the housing 1, respectively. The housing 1 is fixed on the mobile cage 9. A rope diameter detection mechanism is provided inside the sliding sleeve 3 for detecting the rope diameter of the guide rope 10. A wear detection mechanism is provided on the telescopic cantilever 2 for detecting the wear of the guide sleeve 12.

[0070] This invention provides an automatic detection system for hoisting cage ropes in vertical shafts. Through a wireless connection between an intelligent detection module and a centralized control module, it enables automatic fault detection of the cage rope 10. It integrates a rope diameter detection mechanism and a wear detection mechanism to detect the rope diameter of the cage rope 10 and the wear of the guide sleeve 12 of the moving cage 9 during its movement. The real-time detection results are transmitted to the centralized control module via wireless connection, reducing the number of personnel in the vertical shaft, lowering the safety risks of the detection work, and greatly improving the detection accuracy and efficiency.

[0071] In this invention, 4×N guide ropes 10 are vertically fixed inside the shaft, where N is an integer greater than 1. A movable cage 9 is slidably positioned between every four guide ropes 10. Each movable cage 9 has a can ear 11 at its four upper and lower corners for sliding connection with the guide ropes 10. A guide sleeve 12 is installed inside the can ear 11 and fitted onto the guide rope 10. As the movable cage 9 slides, the guide sleeve 12 wears. The total gap between the guide rope 10 and the guide sleeve 12 must not exceed 15mm. When the wear of the guide sleeve 12 or the total gap between the guide rope 10 and the guide sleeve 12 reaches the following limits, it must be replaced. This invention uses a wear detection mechanism to monitor the wear of the guide sleeve 12 on the movable cage 9 in real time, enabling timely detection and replacement of faults to avoid safety issues.

[0072] Because the detection module operates in the vertical shaft, it is limited by the height of the working space, installation space and operating space. The detection module's housing 1 integrates electrical and mechanical mechanisms. The housing 1 is a double-layer stainless steel housing with dimensions of 300×300×600mm, which is convenient for operation and movement. The total weight of the sliding sleeve 3, telescopic cantilever 2 and housing 1 does not exceed 30Kg, and the telescopic cantilever 2 is 300mm long.

[0073] The present invention provides, by way of example, the specific structure of the lifting mechanism as follows:

[0074] The lifting mechanism includes a drum, a drive wheel, a conveyor belt, and a lifting rope. The conveyor belt connects the drum and the drive wheel. The rotation of the drum drives the drive wheel to rotate. The lifting rope is wound around the surface of the drive wheel. Each end of the lifting rope is connected to a mobile cage 9. As the drive wheel rotates, one mobile cage 9 is lowered while the other mobile cage 9 is raised.

[0075] In some embodiments, a rotating platform 4 is provided on the top of the housing 1, and the end of the telescopic cantilever 2 away from the sliding sleeve 3 is rotatably connected to the rotating platform 4.

[0076] The telescopic cantilever 2 rotates around the rotary table 4 on the detection plane, which is a horizontal plane perpendicular to the moving direction of the movable cage 9.

[0077] In this invention, the moving direction of the movable cage 9 is set as the Y-axis (that is, the central axis of the rotary table 4), and the direction perpendicular to the moving direction of the movable cage 9 is set as the X-axis. The telescopic cantilever 2 can translate on the X-axis, resulting in translational displacement. At the same time, it can rotate on the horizontal plane where the X-axis is located, about the center of the Y-axis, resulting in angular displacement.

[0078] In some embodiments, a control device is provided inside the housing 1, and the control device is electrically connected to the rope diameter detection mechanism, the wear detection mechanism and the central control module respectively.

[0079] The detection module in this invention encompasses functions such as data acquisition, data analysis, and data storage. The control device within housing 1 is electrically connected to the rope diameter detection mechanism and the wear detection mechanism. Based on the data collected by the rope diameter detection mechanism and the wear detection mechanism, it performs data analysis and conversion, and transmits the data to the centralized control module. The centralized control module, based on the received information and various threshold parameter settings, performs analysis, judgment, and execution functions.

[0080] In some embodiments, a positioning mechanism 15 is provided at the bottom of the sliding sleeve 3. The positioning mechanism 15 is electrically connected to the control device. The positioning mechanism 15 is used to determine the location of the fault point and transmit it to the control device, which then feeds back to the centralized control module. The positioning mechanism 15 of this invention enables real-time detection of the specific position of the housing 1 in the shaft and simultaneously determines the fault location, thereby improving detection accuracy and facilitating subsequent maintenance.

[0081] In some embodiments, the container 1 is fixed to the mobile cage 9 by a fixing bracket 13. In this invention, the fixing bracket 13 has a self-locking mechanism and a foot-operated unlocking mechanism, ensuring convenient installation and removal of the container 1, saving time and effort. To prevent accidental contact with the lifting plate of the container 1, such as accidental stepping or falling objects causing automatic unlocking and potential accidents, the lifting plate can only be unlocked and removed by a person stepping on it. The entry port of the fixing bracket 13 uses a chamfered slope, making the insertion of the container 1 very smooth and saving installation time.

[0082] In some implementations, such as Figure 1 As shown, the wear detection mechanism includes a first displacement detection element 5 and a second displacement detection element 6, which are disposed within the rotary table 4. The first displacement detection element 5 is used to detect a first displacement, which is the linear translation of the telescopic cantilever 2 on the detection plane. The second displacement detection element 6 is used to detect a second displacement, which is the angle of movement of the telescopic cantilever 2 on the detection plane.

[0083] The first displacement detection element 5 and the second displacement detection element 6 are electrically connected to the control device. The first displacement detection element 5 and the second displacement detection element 6 respectively collect the first displacement amount and the second displacement amount and transmit them to the control device. The control device converts the first displacement amount and the second displacement amount into wear amount electrical signals and transmits them to the centralized control module.

[0084] In this invention, the first displacement detection element 5 and the second displacement detection element 6 are hidden inside the rotary table 4. The first displacement detection element 5 collects the first displacement signal of the telescopic cantilever 2 on the X-axis, mainly capturing the horizontal wear of the guide sleeve 12 in the X-axis. The second displacement detection element 6 collects the second displacement signal of the telescopic cantilever 2 on the Y-axis, mainly capturing the wear of the guide sleeve 12 in the Y-axis. The first and second displacement signals are transmitted to the control device. After processing by the program, the control device calculates the actual wear data of the guide sleeve 12 and transmits it to the centralized control module. The centralized control module executes the corresponding function according to the received information.

[0085] This invention does not impose specific requirements or limitations on the first displacement detection element 5 and the second displacement detection element 6. Any detection element that can achieve the same or similar functions can be used in this invention, and the resulting technical solution also falls within the protection and disclosure scope of this invention. For example, the first displacement detection element 5 can be a linear displacement detection sensor horizontally mounted on the X-axis, such as a precision miniature self-resetting linear displacement sensor. The second displacement detection element 6 can be a rotational angle displacement detection sensor vertically mounted on the Y-axis, achieving 0–360° detection without blind spots, such as a miniature precision Hall GT angle displacement sensor.

[0086] In some implementations, such as Figure 2 As shown, the rope diameter detection mechanism includes at least three third displacement detection elements 7 arranged circumferentially along the inner wall of the sliding sleeve 3, forming a detection loop around the guide rope 10. A detection wheel 8 is provided at one end of each third displacement detection element 7 near the guide rope 10, and the detection wheel 8 abuts against the guide rope 10.

[0087] The third displacement detection element 7 is electrically connected to the control device. The third displacement detection element 7 collects the change in rope diameter and transmits it to the control device. The control device analyzes and processes the change in rope diameter and transmits it to the centralized control module.

[0088] In this invention, after the sliding sleeve 3 is fixed to the outer periphery of the guide rope 10, at least three third displacement detection elements 7 are positioned abutting the outer surface of the guide rope 10. Since the guide rope 10 is a stationary track, during the detection process, the third displacement detection elements 7 in the sliding sleeve 3 form a rope diameter detection loop around the guide rope 10. The rope diameter detection loop moves parallel to the guide rope 10 along with the moving cage 9. During this movement, the third displacement detection elements 7 detect the physical quantity of the rope diameter change and transmit it to the control device for data processing. The control device then wirelessly uploads the processed data electrical signal to the central control module. The third displacement detection element 7 in this invention can be a linear displacement detection sensor.

[0089] In this invention, at least three third displacement detection elements 7 form a detection ring. When the number of third displacement detection elements 7 is even, the third displacement detection elements 7 are symmetrically arranged in pairs along the circumferential direction on the inner wall of the sliding sleeve 3. Normal wear detection, internal rust bulging detection, and external damage deformation detection of the can guide rope 10 diameter (￠45mm) are performed. After comparing the detected values ​​with the benchmark set values, the actual rope diameter is obtained.

[0090] In some embodiments, the sliding sleeve 3 includes a first housing and a second housing, the first housing and the second housing having the same semi-cylindrical structure, and the axial edges of the first housing and the second housing on both sides being aligned and fastened to form the sliding sleeve 3.

[0091] One side of the first housing is hinged to one side of the second housing, and the other side of the first housing is snap-fitted to the other side of the second housing.

[0092] In some embodiments, a first positioning wheel 14 is provided at the upper and lower ends of the first housing along the axial direction, and a second positioning wheel is provided at the upper and lower ends of the second housing along the axial direction. The first positioning wheel 14 and the second positioning wheel abut against the can guide rope 10 for positioning.

[0093] The first positioning wheel 14 and the second positioning wheel are symmetrically arranged. In this invention, the first housing and the second housing are respectively caged and locked with the can guide rope 10, and four positioning wheels are symmetrically installed at the upper and lower ends to hold the can guide rope 10 tightly. The four positioning wheels and the can guide rope 10 form a tight rolling friction, so that the sliding sleeve 3 and the can guide rope 10 are integrated into one.

[0094] In some embodiments, the centralized control module includes an alarm mechanism and an emergency stop mechanism. The alarm mechanism and the emergency stop mechanism are independently and electrically connected to the control device inside the housing 1. The control device triggers the alarm mechanism to issue an alarm or triggers the emergency stop mechanism to shut down the lifting module based on the collected first displacement, second displacement and rope diameter change.

[0095] The control device in this invention processes the first displacement, the second displacement, and the change in rope diameter to obtain a data electrical signal, and uploads the data electrical signal to the centralized control module. The centralized control module analyzes the received data signal and controls the alarm mechanism to issue an alarm, or triggers the emergency stop mechanism to shut down the hoisting module.

[0096] In some embodiments, the guide sleeve 12 includes a first sleeve and a second sleeve, the first sleeve and the second sleeve being identical semi-cylindrical structures, and the axial edges on both sides of the first sleeve and the second sleeve being aligned and fitted together to form the guide sleeve 12. The difference between the diameter of the guide sleeve 12 and the diameter of the guide rope 10 is ≤5mm.

[0097] In this invention, the semi-cylindrical first and second sets of bodies are both embedded inside the ear 11 of the movable cage 9. The cage guide rope 10 passes through the internal space of the guide sleeve 12, with a 1mm sliding space between them. The sliding space is filled with high-viscosity lubricating oil, which on the one hand can ensure effective lubrication between the cage guide rope 10 and the guide sleeve 12, extending the service life of the cage guide rope 10, and on the other hand can prevent water in the vertical shaft from seeping into the interior of the cage guide rope 10, thereby causing rust and corrosion inside the cage guide rope 10.

[0098] In another specific embodiment, the present invention provides an automatic detection method for vertical shaft hoisting guide ropes. The automatic detection method employs an automatic detection system for vertical shaft hoisting guide ropes as described in a specific embodiment. The automatic detection method includes:

[0099] The lifting mechanism drives the mobile cage 9 to move along the guide rope 10. During the movement of the mobile cage 9, the wear detection mechanism detects the wear of the guide sleeve 12, and the rope diameter detection mechanism of the detection module detects the rope diameter of the guide rope 10. The rope diameter detection results and wear detection results are fed back to the central control module.

[0100] The automatic detection method for hoisting guide ropes provided by this invention replaces the traditional manual sampling inspection of guide ropes with automatic real-time detection, which improves detection efficiency and accuracy. At the same time, it saves labor intensity and reduces work safety risks.

[0101] In some specific embodiments, the rope diameter detection includes:

[0102] The rope diameter detection mechanism uses at least three third displacement detection elements 7 to form a detection ring around the guide rope 10. The detection ring moves along the guide rope 10 with the sliding sleeve 3, and collects the physical quantity of rope diameter change during the movement to obtain the rope diameter change amount, which is then transmitted to the central control module.

[0103] In some specific embodiments, the wear detection includes:

[0104] The first displacement detection element 5 of the wear detection mechanism detects the linear translation of the telescopic cantilever 2 on the detection plane to obtain the first displacement. The second displacement detection element 6 detects the movement angle of the telescopic cantilever 2 on the detection plane to obtain the second displacement. The detection module integrates and analyzes the first and second displacements, converts them into wear quantity electrical signals, and transmits them to the central control module.

[0105] The central control module analyzes the electrical signals and controls the alarm mechanism to issue an alarm, or triggers the emergency stop mechanism to shut down the lifting module.

[0106] To help those skilled in the art better understand the overall technical solution and working process of the present invention, the present invention provides the following exemplary automatic detection process:

[0107] (1) Fix the box 1 to the mobile cage 9 through the fixed bracket 13. The first shell and the second shell of the sliding sleeve 3 respectively hug and lock the cage with the cage rope 10. Four positioning wheels are symmetrically installed at the upper and lower ends to hug the cage rope 10. The four positioning wheels and the cage rope 10 form a tight rolling friction, so that the sliding sleeve 3 and the cage rope 10 are integrated into one.

[0108] (2) Rotate the drum and drive the drive wheel to rotate. The two ends of the lifting rope are connected to a mobile cage 9 respectively. As the drive wheel rotates, one mobile cage 9 is lowered while the other mobile cage 9 is raised.

[0109] (3) After the sliding sleeve 3 is closed and locked, the detection wheels 8 of the four adjusted third displacement detection pieces 7 abut against the outer surface of the closed can guide rope 10 to form a detection ring around the can guide rope 10. As the sliding sleeve 3 moves along the can guide rope 10, the physical quantity of the rope diameter change is collected during the movement and transmitted to the control device.

[0110] The control device presets a reference value. After comparing the reference value with the received detection value, the control device obtains the actual rope diameter, analyzes the detection results of whether the guide rope 10 is normal wear, internal rust bulging or external damage deformation, and uploads it to the central control module. The central control module analyzes the electrical signal and controls the alarm mechanism to issue an alarm or triggers the emergency stop mechanism to shut down the hoisting module.

[0111] (4) The first displacement detection element 5 of the wear detection mechanism detects the linear translation of the telescopic cantilever 2 on the detection plane to obtain the first displacement. The second displacement detection element 6 detects the movement angle of the telescopic cantilever 2 on the detection plane to obtain the second displacement. The detection module integrates and analyzes the first displacement and the second displacement, converts them into wear amount electrical signals, and transmits them to the central control module. The central control module analyzes the electrical signals and controls the alarm mechanism to issue an alarm or triggers the emergency stop mechanism to shut down the lifting module.

Those skilled in the art should understand that any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention fall within the protection and disclosure scope of the present invention.

Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.
