[0002] Mine hoisting refers to the transportation of ore, coal, waste rock or gangue along the mine shaft, as well as the lifting of personnel, equipment and instruments. The classification of mine hoisting methods is shown in the table. Among them, wire rope hoisting is the most widely used. The types of wire ropes used include phosphate-coated wire ropes, galvanized wire ropes and smooth wire ropes. The vertical shaft hoisting system in mine hoisting adopts a variety of different designs to adapt to mine operations of different scales and purposes. The tankway inspection of the vertical shaft hoisting system refers to the inspection and maintenance of the tankway in the vertical shaft hoisting system to ensure its normal operation and safety. The tankway is an important part of the vertical shaft hoisting system. It is mainly used to limit the lateral displacement of the lifting container during the lifting process to ensure its safe and stable operation along the shaft direction. The main contents of the tankway inspection include the inspection of the deformation, wear, vibration and other conditions of the tankway to ensure its normal function and avoid safety accidents caused by tankway failure.

[0003] The patent with publication number CN115231417B discloses a tankway detection device and detection method for a vertical shaft hoisting system, comprising a tankway and a base, on which one or two detection device bodies are installed to perform single-side or double-side detection; the detection device body comprises a pre-tightening device, a roller and a supporting device, one end of the pre-tightening device is connected to the base through the supporting device, and a roller is installed on the other end of the pre-tightening device, and the circumferential surface of the roller is tightly fitted with the adjacent tankway wall; the detection device body also comprises an explosion-proof box, in which a data acquisition device and a power supply are placed, a slider displacement sensor and an acceleration sensor are also installed on the supporting device, and an inclination sensor is also installed on the base, and the inclination sensor, the displacement sensor and the acceleration sensor are connected to the data acquisition device through a connecting line; the efficiency of the existing vertical shaft tankway detection can be improved, and missed detection and wrong detection of tankway defects can be avoided, which is suitable for regular diagnosis of the vertical shaft hoisting tankway, and can make the vertical shaft hoisting operation safer and more efficient.

[0004] The above-mentioned device can detect the inclination angle of the rope during use, but the tank container pulled by the steel cable will shake when it stops or starts during the descent.

[0019] Step 4: When the roller follower is locked with the centrifugal slider, the roller follower is synchronously engaged with the roller adjusting member, so that after the motor stops, the roller follower is still able to rotate due to inertia, thereby reducing the impact force on the first steel cable.

[0020] The beneficial effects of the present invention are:

[0021] 1. The present invention discloses a tankway detection device and detection method for a vertical shaft hoisting system, which detects the surface vibration of multiple first steel cables when they are moving through a camera, and quickly rotates the locking ring on the locking device after the first steel cable breaks, so that the centrifugal slider is instantly subjected to a large centrifugal force, driving the second limit column on the roller follower to engage with the centrifugal slider, thereby locking the locking ring, and the first roller plate and the locking ring realize the clamping effect on the first steel cable, and the first roller plate and the locking ring stop rotating, thereby reducing the risk of the remaining first steel cables being subjected to excessive force and causing breakage after the first steel cable breaks, thereby improving the safety of the tank container during use and detection.

[0035] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0036] like Figure 1 to Figure 2 As shown, a tankway detection device for a vertical shaft hoisting system according to an embodiment of the present invention comprises a motor support block 1, a steel cable reel 11 is arranged on the motor support block 1, a first steel cable 12 is arranged on the steel cable reel 11, a tank box 16 is connected to the end of the first steel cable 12, a top support frame 13 is arranged on the side of the motor support block 1, a cable adjustment roller 18 and a first support column 14 are arranged on the top support frame 13, a bottom support block 15 is arranged on the first support column 14, a second support block 19 and a block 2 are arranged on the bottom support block 15,

[0037] like Figure 3 to Figure 4 As shown, a camera 21 is provided on the side wall of the block 2, and an adjusting device 3 is provided on the side of the second supporting block 19; the adjusting device 3 comprises a first mounting block 31, a roller adjusting member 35 and a roller following member 36, and the tension of the first steel cable 12 is adjusted by adjusting the distance between the first mounting block 31 and the roller adjusting member 35, and the roller following member 36 limits the roller adjusting member 35, and a locking device 4 is connected to the roller following member 36;

[0038] like Figures 7 and 8As shown, the locking device 4 includes a locking ring 41 and a centrifugal slider 43. The plurality of first steel cables 12 drive the tank box 16 to rise and fall. The camera 21 takes photos of the plurality of first steel cables 12 for detection. When the first steel cable 12 turns and breaks, the centrifugal slider 43 engages and locks with the roller follower 36 to protect the first steel cable 12 from being broken by force.

[0039] It should be noted that when inspecting the tank channel of the vertical shaft hoisting system, the degree of wear of multiple first steel cables 12 during use may be different. If one of them is severely worn during use, it will break when passing through the bending tension adjustment of the roller adjustment member 35 and the locking ring 41. Once the first steel cable 12 breaks, the remaining first steel cables 12 will be subjected to excessive force and continue to break when descending and ascending. Therefore, if one of the first steel cables 12 breaks when passing through the bending part of the roller adjustment member 35 and the locking ring 41, it can be clamped in time to prevent the remaining first steel cables 12 from being subjected to excessive force. In order to solve this problem, the following improvements have been made:

[0040] First, the motor is used to drive the steel cable reel 11 to rotate, and the steel cable reel 11 drives the first steel cable 12 to move, so that the tank box 16 at the end of the first steel cable 12 rises or falls. When the first steel cable 12 passes through the center of the bottom support block 15, multiple cameras 21 arranged on the bottom support block 15 take pictures of the multiple first steel cables 12 to observe the shaking phenomenon of the first steel cables 12 during the lifting process. The top of the bottom support block 15 is provided with a second support block 19. When the first steel cable 12 passes through the adjusting device 3 connected to the center of the second support block 19, it can The tension of the first steel cable 12 is adjusted to prevent the problem of uneven tension of the first steel cable 12 during use. The side wall of the second support block 19 is symmetrically installed with a cable adjustment block 17. The end of the cable adjustment block 17 is rotatably installed with a cable roller 171. After passing through the cable adjustment roller 18, the first steel cable 12 passes through the outer wall of the cable roller 171, and then the tension is adjusted by the adjustment device 3. The roller adjustment member 35 and the locking ring 41 at the end of the roller follower 36 on the adjustment device 3 follow the movement and rotation of the first steel cable 12, and the cable roller 171 at the bottom is rotated. 171 passes through, so that the first steel cable 12 always maintains the center position of the bottom support block 15. When one of the first steel cables 12 is bent and broken after passing through the roller adjustment member 35 and the locking ring 41, the locking ring 41 rotates rapidly. The locking ring 41 rotates rapidly, so that the centrifugal slider 43 inside the locking ring 41 instantly generates a large centrifugal force, thereby driving the centrifugal slider 43 to move. The movement of the centrifugal slider 43 can engage with the roller follower 36, thereby locking the locking ring 41 and the roller adjustment member 35. The locking ring 41 and the roller adjustment member 35 stop. The rotation is stopped and the first steel cable 12 is clamped to prevent the first steel cable 12 from detaching, while the broken first steel cable 12 still holds the tank box 16, thereby protecting the tank box 16 and the remaining first steel cables 12, and preventing the remaining first steel cables 12 from being broken again due to excessive force. The broken first steel cable 12 is repaired, and then the telescopic rod on the roller follower 36 is started to reset the roller follower 36, so that the roller adjusting member 35 and the locking ring 41 are no longer locked by the roller follower 36, and the reset work is completed.

[0041] like Figures 1 to 3As shown, a camera slot 22 is opened at the center of the bottom support block 15, and the camera slot 22 is used for the first steel cable 12 to vertically pass through the center of the bottom support block 15. A second support rod 191 is fixedly installed on the top side of the bottom support block 15, and a second support block 19 is fixedly installed on the outer wall of the second support rod 191. A cable adjustment block 17 is symmetrically installed on the side wall of the second support block 19, and a cable roller 171 is rotatably installed on the end of the cable adjustment block 17. The outer wall of the cable roller 171 contacts the first steel cable 12, and an adjusting device 3 is fixedly installed at the side center of the second support block 19. The adjusting device 3 is used to adjust and detect the tension of the first steel cable 12.

[0042] It should be noted that a camera slot 22 is provided inside the bottom support block 15, and the camera slot 22 is located at the center of the bottom support block 15, so as to facilitate the first steel cable 12 to pass through the inside of the bottom support block 15, so that the angle of the first steel cable 12 is parallel to the movement direction, and the design of the two cable rollers 171 ensures that the first steel cable 12 is still at the center of the bottom support block 15 after multiple turns, thereby maintaining the stability of the tank box 16 during lifting and lowering, and the adjusting device 3 can be adjusted to ensure that the tension of each first steel cable 12 is the same.

[0043] like Figures 4 to 5 As shown, the adjusting device 3 includes a first mounting block 31 fixedly mounted at the side center of the second supporting block 19, a first sliding rod 32 is fixedly mounted on the end of the first mounting block 31, a second sliding rod 33 is slidably mounted inside the first sliding rod 32, a first spring 34 is fixedly mounted on the side wall of the first sliding rod 32, the second sliding rod 33 is concentric with the first spring 34, a roller adjusting member 35 is fixedly mounted on the end of the second sliding rod 33, a roller follower 36 is provided at the end of the roller adjusting member 35, a locking device 4 is provided on the roller follower 36, and the roller adjusting member 35 and the roller follower 36 cooperate to lock the locking device 4.

[0044] It should be noted that when the tension needs to be adjusted, the distance between the first mounting block 31 and the roller adjusting member 35 can be adjusted so that the first slide bar 32 and the second slide bar 33 are combined into a telescopic rod that can be extended and retracted, and the outer wall of the second slide bar 33 is provided with a first spring 34 to protect the tank box 16 at the moment of starting and stopping to prevent the first slide bar 32 and the second slide bar 33 from being subjected to excessive force. The roller follower 36 can lock the roller adjusting member 35 and the locking device 4 to prevent the roller adjusting member 35 and the locking device 4 from being separated from the first steel cable 12 after the first steel cable 12 breaks, causing the remaining first steel cables 12 to be subjected to excessive force.

[0045] like Figures 5 to 7As shown, the roller adjustment member 35 includes a first adjustment plate 351 fixedly mounted on the end of the second sliding rod 33, a first roller plate 352 is rotatably mounted on the end of the first adjustment plate 351, a cable roller 353 is fixedly mounted on the side wall of the first roller plate 352, a first limiting groove 3521 is provided in the inner circumferential array of the first roller plate 352, and a roller follower 36 is rotatably mounted on the outer side wall of the first adjustment plate 351.

[0046] It should be noted that the cable roller 353 is used to contact the outer wall of the first steel cable 12, the first roller plate 352 is used to limit the first steel cable 12, and the first limiting groove 3521 provided on the side wall of the first roller plate 352 is used to cooperate with the roller follower 36, so as to lock the first roller plate 352 and the cable roller 353 to prevent the first roller plate 352 and the cable roller 353 from continuing to rotate after the first steel cable 12 breaks.

[0047] like Figures 5 to 7 As shown, the roller follower 36 includes a first rotating column 361 and a second rotating column 3611 rotatably mounted on the outer side wall of the first adjusting plate 351, the outer wall of the first rotating column 361 is fixedly mounted with a first protrusion 363, the side wall of the first protrusion 363 is fixedly mounted with a first telescopic rod 364, the end of the first telescopic rod 364 is fixedly mounted with a second slide plate 365, the outer wall of the second slide plate 365 is fixedly mounted with a fourth sliding rod 362, the end of the fourth sliding rod 362 is fixedly mounted with a fourth limiting column 369, the fourth limiting column 369 is used to engage with the first limiting groove 3521, the first limiting groove 3521 is fixedly mounted with a fourth limiting column 369, and the first limiting groove 3521 is fixedly mounted with a fourth limiting column 369. A third slider 366 is rotatably installed on the side wall of the second slide plate 365, and a second telescopic rod 368 is fixedly installed on the side wall of the third slider 366. The second telescopic rod 368 is fixedly installed with the locking device 4, and the second telescopic rod 368 rotates synchronously with the locking device 4. A second limiting column 367 is fixedly installed on the end of the third slider 366, and the second limiting column 367 is used to engage with the locking device 4. The first rotating column 361 and the second rotating column 3611 are fixedly installed with a first limiting column 3612 on the end side walls, and the first limiting column 3612 passes through the interior of the locking device 4.

[0048] It should be noted that the first rotating column 361 and the second rotating column 3611 are connected to the first adjusting plate 351 by a torsion spring. When the locking ring 41, the first roller plate 352 and the cable roller 353 do not lock the first steel cable 12, the first rotating column 361 and the second rotating column 3611 are in a state of Figure 7When the locking ring 41, the first roller plate 352 and the cable roller 353 clamp and lock the first steel cable 12, the first steel cable 12 will generate elastic force due to its breakage. Even if the locking ring 41, the first roller plate 352 and the cable roller 353 clamp the first steel cable 12, the first steel cable 12 will still drive the locking ring 41, the first roller plate 352 and the cable roller 353 to rotate a certain angle. Therefore, the first adjustment plate 351 and the second rotating column 3611 can not only play a buffering role after the first steel cable 12 breaks, but also clamp the first steel cable 12 after it breaks, preventing the broken first steel cable 12 from being subjected to tension. The first protrusion 363 is provided with a first telescopic rod 364, and the first telescopic rod 364 is telescopic to drive the second slide plate 365 to move in the direction close to the locking ring 41. Thereby, the fourth limiting column 369 at the end of the fourth sliding rod 362 is driven to engage with the first limiting groove 3521, and the third sliding block 366 is rotatably installed on the side of the second sliding block 365, and second telescopic rods 368 are arranged on both sides of the third sliding block 366, and the second telescopic rods 368 are connected to the locking device 4, so that the third sliding block 366 can rotate along with the locking device 4, and the second limiting column 367 at the end of the third sliding block 366 can engage with the locking device 4, so as to lock the locking device 4, and the first limiting column 3612 arranged at the end of the second rotating column 3611 is fixedly connected with the second rotating column 3611, so that the first limiting column 3612 does not rotate during the rotation of the locking device 4, and when the second limiting column 367 engages with the locking device 4, the first limiting column 3612 can stop the locking ring 41 from rotating.

[0049] like Figures 7 and 8 As shown, the locking device 4 includes a locking ring 41 rotatably mounted on the outer wall of the first limiting column 3612, a third limiting plate 42 is symmetrically mounted inside the locking ring 41, a centrifugal slider 43 is slidably mounted on the side wall of the third limiting plate 42, a first tooth 44 is fixedly mounted on the inner wall of the centrifugal slider 43, a second protrusion 46 is fixedly mounted on the end of the centrifugal slider 43, a locking groove 47 is opened inside the centrifugal slider 43, a third spring 48 is fixedly mounted on the side wall of the centrifugal slider 43, an end of the third spring 48 is fixedly mounted on the inner wall of the locking ring 41, a first gear 45 is fixedly mounted on the outer wall of the first limiting column 3612, and the first gear 45 is located at the inner center of the locking ring 41.

[0050] It should be noted that when the first steel cable 12 breaks and causes the locking ring 41 to rotate faster, the centrifugal slider 43 is driven to slide on the inner wall of the third limiting plate 42, and the end of the centrifugal slider 43 is provided with a second protrusion 46. Therefore, during the rotation of the locking ring 41, the centrifugal slider 43 slides in the direction of the second protrusion 46. When the second protrusion 46 contacts the inner wall of the locking ring 41, the first tooth 44 engages with the first gear 45, and the first gear 45 is fixedly installed on the first limiting column 3612, and the first limiting column 3612 does not rotate. Therefore, during the rotation of the locking ring 41, the first gear 45 still does not rotate, thereby stopping the locking ring 41 from rotating, and a locking groove 47 is provided inside the centrifugal slider 43, and the locking groove 47 and the second limiting column 3612 are engaged with each other. The column 367 is engaged to prevent the locking ring 41 from stopping rotating. After that, the centrifugal slider 43 is subjected to the elastic force of the third spring 48 and is reset. The first tooth 44 is no longer engaged with the first gear 45, and the second limiting column 367 is engaged with the locking groove 47, so that after the locking ring 41 and the first roller plate 352 and the cable roller 353 clamp the first steel cable 12, the locking ring 41 can continue to clamp and lock even if it does not rotate, so as to protect it after the first steel cable 12 breaks and prevent the remaining first steel cables 12 from being subjected to excessive force. When the centrifugal slider 43 needs to be reset, the first telescopic rod 364 can be started to retract, and the second limiting column 367 is disengaged from the locking groove 47, and the reset is completed under the action of the third spring 48.

[0051] like Figure 6 to Figure 7 As shown, the first rotating column 361 and the second rotating column 3611 are rotatably mounted on the outer side wall of the first adjusting plate 351, and a torsion spring is provided at the connecting portion between the first rotating column 361 and the first adjusting plate 351, and a torsion spring is provided at the connecting portion between the second rotating column 3611 and the first adjusting plate 351.

[0052] It should be noted that a torsion spring is provided at the connection position between the first rotating column 361 and the first adjusting plate 351, and a torsion spring is provided at the connection position between the second rotating column 3611 and the first adjusting plate 351. When the first steel cable 12 is broken, when the first roller plate 352, the cable roller 353 and the locking ring 41 clamp the first steel cable 12, the first steel cable 12 still has elasticity after breaking, and the torsion spring can play a role in rotation and buffering.

[0053] like Figures 2 to 3 As shown, the cable adjusting roller 18 is provided with a plurality of grooves, the cable reel 11 is provided with a plurality of first steel cables 12 passing through the grooves on the cable adjusting roller 18, and the side wall of the second support block 19 is correspondingly provided with a plurality of the cable adjustment blocks 17 and a plurality of the adjustment devices 3.

[0054] It should be noted that the plurality of first steel cables 12 correspond to the plurality of cable adjustment blocks 17 and the adjustment device 3, so that the first steel cables 12 will not deviate when they are raised or lowered.

[0055] like Figure 8 As shown, the length of the centrifugal slider 43 is smaller than the diameter of the locking ring 41 , so that the centrifugal slider 43 slides on the inner wall of the third limiting plate 42 .

[0056] It should be noted that the length of the centrifugal slider 43 is smaller than the diameter of the locking ring 41 , so that the centrifugal slider 43 slides on the inner wall of the third limiting plate 42 .

[0057] A method for detecting a tank channel of a vertical shaft hoisting system, the method adopts the above-mentioned tank channel detection device of the vertical shaft hoisting system, and comprises the following steps:

[0058] Step 1: First, start the motor to drive the steel cable reel 11 to rotate. The rotation of the steel cable reel 11 drives the first steel cables 12 to move, so that the tank box 16 at the end of the first steel cable 12 is lifted or lowered. The lifting of the tank box 16 causes the first steel cables 12 to pass through the camera slot 22. When the first steel cable 12 passes through the camera slot 22, the camera 21 detects the shaking degree of the first steel cable 12 and the outer surface of the first steel cable 12.

[0059] Step 2: When the first steel cable 12 is rapidly descending, the roller follower 36 on the adjusting device 3 and the locking ring 41 on the locking device 4 bend the first steel cable 12, and at the same time, the first steel cable 12 drives the locking ring 41 and the roller follower 36 to rotate, and the distance between the roller follower 36 and the first mounting block 31 is adjusted, so that the tension on the first steel cable 12 can be adjusted;

[0060] Step 3, when the first steel cable 12 is bent and broken after passing through the roller follower 36 and the locking device 4, the locking ring 41 on the locking device 4 rotates rapidly, and the rotation of the locking ring 41 causes the centrifugal slider 43 to be subjected to centrifugal force, driving the centrifugal slider 43 to move, and the movement of the centrifugal slider 43 causes the roller follower 36 to lock the centrifugal slider 43, preventing the first steel cable 12 from escaping from the clamping of the locking ring 41 and the roller follower 36, thereby reducing the impact on the remaining first steel cables 12;

[0061] Step 4: When the roller follower 36 is locked with the centrifugal slider 43, the roller follower 36 is synchronously engaged with the roller adjusting member 35, so that the roller follower 36 can still rotate due to inertia after the motor stops, thereby reducing the impact force on the first steel cable 12.

[0062] The above describes an embodiment of the present embodiment, but the present embodiment is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present embodiment, ordinary technicians in this field can also make many forms, all of which are protected by the present embodiment.
