Description

Technical Field

[0001] This invention relates to testing equipment technology, specifically to a testing method for a differential connection device in a vertical shaft tank passage. Background Technology

[0002] As the lifeline of coal mine production, mine hoisting equipment is the core hub connecting the surface and underground. The hoisting system, as the guiding device for the hoisting system in the vertical shaft, plays a vital role in ensuring the stable, safe and rapid operation of the hoisting container.

[0003] 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.

[0004] During long-term operation of hoisting equipment, vertical shaft guideways are affected by factors such as geological tectonic movements, impacts from the hoisting container, corrosion from humid environments, and the hardening and adhesion of contaminants, resulting in some degree of overall or localized deformation. These defects act as excitation inputs during the operation of the hoisting container, causing it to be subjected to varying degrees of impact and generate adverse vibrations. This exacerbates the lateral and longitudinal vibrations of the hoisting wire rope, and in severe cases, can lead to wire rope breakage, hoisting container derailment or jamming, personnel injuries, and other problems, affecting the safe and efficient operation of the coal mine. Therefore, defect detection in vertical shaft guideways is of great significance.

[0005] Chinese invention patent CN115771825A discloses an automatic detection system and method for hoisting cage ropes in vertical shafts. This automatic detection system and method replaces the traditional manual sampling inspection of cage ropes with automatic real-time detection. Through the wireless connection between the intelligent detection module and the centralized control module, automatic fault detection of the cage ropes is achieved. It integrates a rope diameter detection mechanism and a wear detection mechanism to detect the rope diameter and the wear of the guide sleeve of the moving cage during the movement of the moving cage. This reduces the number of personnel in the vertical shaft, lowers the safety risks of the inspection work, and greatly improves the detection accuracy and efficiency.

[0006] When existing equipment is in use, the cage operates at a high speed during the lifting and transportation process, which can cause excessive friction when one end of the cage shakes or sways, making it prone to accidents. At the same time, most current detection methods are based on post-fault diagnosis or periodic inspection, which lacks sufficient predictability, resulting in poor overall detection results. Therefore, a detection method for the differential connection device of the vertical shaft cage passage has been developed. Summary of the Invention

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 of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0025] Example: Please refer to Figures 1-8 A method for detecting differential connection devices in vertical shaft tank passages includes the following steps: S1. Visual inspection: Check whether the structure of the device is intact and whether the lubricating oil / grease is sufficient; S2. Functional test: No-load or load operation test to observe whether the vertical shaft guideway can move normally; S3. Electrical System Inspection: By simulating the rising and falling of the cage, test whether the electrical control system can respond correctly and check whether the sensors can accurately report the cage status. In S2, the operating status of the main body 1 is detected. A main rope 11 is set at the middle position of the upper end of the main body 1, and auxiliary ropes 12 are set at the upper end of the main body 1 and on both sides of the main rope 11. A positioning component 2 is set on the outer surface of the auxiliary rope 12, and the operating status of the main body 1 is monitored through the positioning component 2.

[0026] In this scheme, the main body 1 is pulled up by the main rope 11 and the auxiliary rope 12, and the auxiliary rope 12 is limited by the positioning component 2, so as to monitor the swaying of the auxiliary rope 12 and ensure the stability of the main body 1 during operation.

[0027] Furthermore, the positioning component 2 includes a connecting block 22 for connection with an external fixing member. A fixing block 21 is provided at the end of the connecting block 22. A support plate 23 is provided on the inner wall of the fixing block 21. A sliding groove 24 is provided at the end of the support plate 23. A positioning rod 25 is slidably installed on the inner wall of the sliding groove 24.

[0028] In this embodiment, the fixing component is connected to the outside of the transport channel to ensure the stability of the positioning component 2. At the same time, the fixing block 21 is limited by the connecting block 22 to ensure the stability of the fixing block 21.

[0029] The positioning rod 25 is constrained by the slide groove 24 so that it will not fall off when it moves.

[0030] Furthermore, an adjusting rod 27 is rotatably mounted on the outer surface of the positioning rod 25, and a first elastic element 26 is provided at the end of the support plate 23. The end of the first elastic element 26 away from the support plate 23 is connected to the outer surface of the adjusting rod 27.

[0031] Specifically, the first elastic element 26 is a spring or other elastic component, which supports the adjusting rod 27. The cross-section of the two adjusting rods 27 is V-shaped, and the auxiliary rope 12 is limited by the protective rod 271 set at the end of the adjusting rod 27.

[0032] Furthermore, a limiting block 211 is provided at the end of the fixing block 21, and an adjusting plate 28 is slidably mounted on the end of the limiting block 211. A guide groove 281 is provided at the end of the adjusting plate 28, and a second elastic member 29 is provided on the inner wall of the guide groove 281. The cross-section of the guide groove 281 is h-shaped, and two second elastic members 29 are provided on the inner wall of the guide groove 281. The ends of the two second elastic members 29 are slidably connected. Specifically, the adjusting plate 28 is supported by the limiting block 211, wherein the end of the adjusting plate 28 is provided with a protrusion, and the end of the limiting block 211 is provided with a groove, and the outer surface of the protrusion is slidably connected to the inner wall of the groove.

[0033] Meanwhile, the protective rod 271 is located on the outer surface of the contact point between the two second elastic elements 29. When the main body 1 shakes, it drives the auxiliary rope 12 to shake, thereby squeezing the protective rod 271 or the baffle 282, causing one of the second elastic elements 29 to contract, and causing the protective rod 271 to move to the inner wall of the other guide groove 281.

[0034] The second elastic element 29 is a spring or other elastic component, and the inner wall of the second elastic element 29 is provided with a sensor or other component that has a signal transmission function, which is used to detect the state of the auxiliary rope 12.

[0035] Furthermore, a protective rod 271 is provided at the end of the adjusting rod 27, and the outer surface of the end of the protective rod 271 is slidably connected to the inner wall of the guide groove 281. A baffle 282 is provided at the end of the adjusting plate 28, and the auxiliary rope 12 is located between the baffle 282 and the protective rod 271.

[0036] Specifically, when the auxiliary rope 12 sways, the protective rod 271 moves, thereby activating the sensor to record the position of the sway when the main body 1 moves, and at the same time detects the position of the raised part of the outer surface of the auxiliary rope 12. When the protrusion caused by the breakage of the outer surface of the auxiliary rope 12 moves between the protective rod 271 and the baffle 282, it pushes the protective rod 271 to move and records the position.

[0037] Furthermore, the detection component 3, which is assembled at the end of the main body 1, detects the operating status of the main body 1. The detection component 3 includes a base plate 31 connected to the upper end of the main body 1, and a limit rod 32 is rotatably mounted on the upper end of the base plate 31. A positioning plate 33 is rotatably mounted on the end of the limit rod 32, and a movable block 35 is rotatably mounted on the end of the positioning plate 33. A support column 34 is provided on the outer surface of the movable block 35.

[0038] In this embodiment, the support column 34 is a telescopic rod or other component with telescopic function, which is used to support the movable block 35 and ensure that the movable block 35 remains stable as a whole when it moves.

[0039] Simultaneously, when the movable block 35 moves, it drives the positioning plate 33 located at its end to move. Since the end of the positioning plate 33 is rotatably connected to the upper end of the base plate 31, the end of the positioning plate 33 is limited by the limiting rod 32, and the positioning plate 33 drives the detection piece 36 to move.

[0040] Furthermore, a slot 311 is formed on the outer surface of the base plate 31, and the inner wall of the slot 311 is slidably connected to the outer surface of the support column 34. The positioning plate 33 has a triangular cross-section, and a detection element 36 is rotatably mounted on the end of the positioning plate 33 away from the movable block 35. The lower end of the detection element 36 is connected to the upper end of the base plate 31.

[0041] Specifically, the support column 34 is constrained by the slot 311 opened on the side of the base plate 31 to ensure that the support column 34 will not interfere when it moves. The detection element 36 is a pressure sensor or other device with pressure detection function and is connected to an external control device.

[0042] Furthermore, a docking block 37 is provided at the end of the movable block 35, and a snap-fit ​​block 38 is provided at the end of the docking block 37. A detection rod 381 is slidably installed on the inner wall of the snap-fit ​​block 38, and the end of the detection rod 381 extends through and to the outside of the snap-fit ​​block 38. At the same time, a pressing block 382 is provided at the end of the detection rod 381.

[0043] Specifically, the ends of the mating block 37 and the snap-fit ​​block 38 are connected, and different snap-fit ​​blocks 38 are adjusted according to the actual situation to make them suitable for different scenarios.

[0044] The extrusion block 382 is a device with pressure detection function, such as an extrusion sensor. The extrusion block 382 detects the detection rod 381, thereby monitoring the operating status of the main body 1 in real time.

[0045] Furthermore, a third elastic element 383 is sleeved on the outer surface of the detection rod 381. One end of the third elastic element 383 is connected to the outer surface of the detection rod 381, and the other end is connected to the outer surface of the snap-fit ​​block 38.

[0046] Specifically, the third elastic element 383 is a spring or other elastic component. The detection rod 381 is supported by the third elastic element 383, thereby pushing the swing block 39 to fit tightly against the inner wall of the transport channel, so that when the main body 1 vibrates or shakes, it can be recorded immediately.

[0047] Furthermore, a swing block 39 is rotatably mounted on the end of the snap-fit ​​block 38, and a roller 391 is rotatably mounted on the end of the swing block 39. At the same time, the outer surface of the swing block 39 is in contact with the end of the detection rod 381.

[0048] Specifically, a torsion spring is provided at the rotatable connection between the swing block 39 and the snap-fit ​​block 38, which is used to support the swing block 39 and, together with the roller 391 rotatably installed at the end of the swing block 39, fits against the inner wall of the transport channel.

[0049] The control device can choose a microcontroller as the control terminal. In this embodiment, the microcontroller is a typical embedded microcontroller unit, consisting of an arithmetic logic unit (ALU), a controller, memory, input / output devices, etc., essentially a miniature computer. Compared to general-purpose microprocessors used in personal computers, it emphasizes self-sufficiency (no external hardware required) and cost savings. Its biggest advantage is its small size, allowing it to be placed inside the instrument, but it has limited storage capacity, simple input / output interfaces, and low power consumption.

[0050] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
