Description

A support device and tilting method for an automatic tilting and turning platform. Technical Field

[0001] This invention relates to the field of mining conveying technology, and in particular to a support device and a method for automatically tilting and overturning a coal dumping platform. Background Technology

[0002] During coal mining, a large amount of coal gangue with low carbon content and difficult to utilize is extracted. This gangue needs to be transported out of the mine and to the surface using mine cars, coal bunkers, belt conveyors, and hoisting equipment. Specifically, a gangue-turning device is used to transfer the gangue from the mine cars to the coal bunker and then to the belt conveyor.

[0003] In the prior art, Chinese Patent No. CN220431347U discloses a coal mine turning machine frame; it includes a triangular main frame, a rail on the top of the triangular main frame, the rail being made of steel, a frame return wheel on the upper right of the rail, an opener / closer on the triangular main frame to the lower left of the frame return wheel, a turning buffer device below the opener / closer, a mine car fixed rotating turning cage on the upper right of the triangular main frame, the width of the mine car fixed rotating turning cage being greater than the triangular main frame and fitting onto the triangular main frame, the left end of the mine car fixed rotating turning cage being locked by the opener / closer, four mine car wheel holders on the upper side of the lower part of the mine car fixed rotating turning cage, a dispatching winch on the left side of the rail, a mine car on the rail, a traction rope connected to the right end of the mine car, the traction rope being made of steel, the traction rope passing to the right around the frame return wheel, passing under the mine car and connecting to the dispatching winch.

[0004] When implementing the above-mentioned scheme, the ore is usually dumped by tipping the mine car to discharge the ore. Since the ore is piled up disorderly in the mine car, the vibration during transportation will cause the ore to be piled up more tightly in the mine car. Therefore, during the dumping process, the ore will get stuck in the mine car. In order to completely dump the ore out of the mine car, it is usually necessary to tip the mine car at a large angle or tip it completely. This makes each dumping of the mine car time-consuming and puts a lot of pressure on the drive mechanism that controls the tipping of the mine car, affecting the service life of the drive mechanism. Summary of the Invention

[0005] Therefore, it is necessary to provide a support device and a tilting method for an automatic tilting and turning platform to address the aforementioned technical problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a support device for an automatically tilting and turning platform, comprising: a support frame, a main shaft rotatably connected to the support frame, a tilting frame fixed on the main shaft, the tilting frame being used to drive the mine car to tilt, a drive assembly for driving the main shaft to rotate being installed on the support frame, and a vibration motor being installed on the tilting frame; a tilting detection mechanism, the tilting detection mechanism being disposed at both ends of the main shaft and installed with the support frame, the tilting detection mechanism comprising a detection half-sleeve positioned below the end of the main shaft and abutting against its bottom surface, sealing plates positioned at both ends of the inner cavity of the detection half-sleeve, and a follower rod inserted into one end of the detection half-sleeve, the end of the follower rod extending into the inner cavity of the detection half-sleeve abutting against the sealing plate, and a distance sensor corresponding to the end of the follower rod away from the sealing plate being installed on the detection half-sleeve.

[0007] As a preferred embodiment of the support device for the automatic tilting and turning platform provided by the present invention, it further includes a tilting intelligent controller. The tilting intelligent controller is mounted on the support frame and is equipped with a tilting detection module and a tilting auxiliary module. The tilting detection module is connected to a distance sensor and the tilting auxiliary module, respectively. The tilting auxiliary module is connected to a drive assembly and a vibration motor, respectively. When the mine car moves onto the tilting frame, the tilting frame is subjected to pressure from the mine car, increasing its weight. The main shaft generates a continuous pressure on the detection half-set. Under this state, the distance sensor sends the detected distance data to the tilting detection module. The tilting auxiliary module controls the drive assembly to work, and the drive assembly drives the main shaft to rotate, controlling the mine car carrying the tilting frame to gradually tilt. During this process, the tilting detection module compares the received distance data with a preset initial distance value. In contrast, when the distance data is greater than the preset initial distance value, the tilting detection module sends an auxiliary signal to the tilting auxiliary module. The tilting auxiliary module then controls the vibration motor to work, which vibrates and causes the tilting frame and mine car to vibrate, assisting in tilting the ore along the inclined mine car. When the distance data is determined by the tilting detection module to drop to the same as the preset initial distance value, it is determined that the ore in the mine car has been tilted. At this time, the tilting detection module sends a reset signal to the tilting auxiliary module, which then controls the vibration motor to stop working and controls the drive component to reset the tilting frame. This achieves real-time monitoring of the ore tilting status in each mine car and automatically determines the tilting status. After tilting is completed, the tilting frame is promptly reset, avoiding the need for each mine car to tilt for a long time. The tilting time of each mine car can be flexibly adjusted, improving the ore tilting efficiency during automatic tilting.

[0008] In a preferred embodiment of the support device for the automatic tilting and turning platform provided by the present invention, the inner cavity of the detection half-set is filled with hydraulic medium between the two sealing plates. The end of the detection half-set away from the follower rod is connected to a pressure regulating pipe, and a solenoid valve is installed on the pressure regulating pipe. By setting the pressure regulating pipe, the pressure at the end of the detection half-set can be increased, and the sealing plate can be moved, thereby controlling the position of the other sealing plate and the follower rod. The position of the follower rod is detected by a distance sensor, and the position of the follower rod is calibrated to improve the detection accuracy of the distance sensor.

[0009] In a preferred embodiment of the support device for the automatic tilting and turning platform provided by the present invention, a bearing is installed at the corresponding position of the main shaft and the detection half-sleeve. The main shaft abuts against the outer ring of the bearing, and the side wall of the detection half-sleeve that abuts against the main shaft is an elastic side wall. By setting the bearing, the wear of the detection half-sleeve by the main shaft can be reduced, the service life of the detection half-sleeve can be improved, and when the main shaft squeezes the detection half-sleeve through the bearing, the bearing will squeeze the elastic side wall on the detection half-sleeve, improving the sensitivity of the change of the inner cavity space of the detection half-sleeve and flexibly controlling the displacement of the follower rod, which is convenient for the distance sensor to perform accurate detection.

[0010] In a preferred embodiment of the support device for the automatic tilting and turning platform provided by the present invention, a proximity switch is installed above the top of the follower rod. An auxiliary top block is abutted at the bottom of the main shaft near the turning detection mechanism. A telescopic motor is installed at the bottom of the auxiliary top block. The tilting intelligent controller is also equipped with a load-bearing protection module. The load-bearing protection module is connected to the proximity switch and the telescopic motor respectively. When the main shaft squeezes the detection half-set, the follower rod will gradually move upward. When the follower rod moves upward and contacts the proximity switch, the proximity switch sends a position signal to the load-bearing protection module. The load-bearing protection module determines that the pressure on the main shaft exceeds the limit and activates the protection mode. The load-bearing protection module controls the telescopic motor to work. The telescopic motor pushes the auxiliary top block to move upward to support the main shaft, reduce the pressure of the main shaft on the detection half-set, and protect the detection half-set, making it less likely to be damaged due to the large weight of the ore.

[0011] In a preferred embodiment of the support device for the automatic tilting and turning platform provided by the present invention, each of the main shafts is provided with an anti-bending detection mechanism at its end. The anti-bending detection mechanism includes a centering rod inserted into the center of the end of the main shaft, a detection cylinder connected to the support frame, and a transmission rod vertically inserted into the top of the detection cylinder. The top of the transmission rod is sleeved with the end of the centering rod. A positioning plate fixed to the bottom of the transmission rod is vertically slidably connected to the inner cavity of the detection cylinder. A distance sensor corresponding to the positioning plate is installed at the bottom of the inner cavity of the detection cylinder.

[0012] As a preferred embodiment of the support device for the automatic tilting and turning platform provided by the present invention, the tilting intelligent controller is also equipped with an anti-bending detection module. The anti-bending detection module is connected to a proximity switch and a telescopic motor. When the main shaft bends, the centers at both ends of the main shaft will jump during the rotation of the main shaft, thereby causing the centering rod connected to the center of the main shaft to jump. This causes the transmission rod to move the positioning plate vertically in the inner cavity of the detection cylinder. At this time, the distance sensor will detect the distance data of the positioning plate in real time and send it to the anti-bending detection module. The anti-bending detection module compares the received distance data with a preset distance threshold. When it is determined that the distance data exceeds the distance threshold, the main shaft is bent to a large degree. The anti-bending detection module issues a corresponding reminder signal to remind the staff to deal with it in time. The reminder signal can be a light or sound reminder.

[0013] In a preferred embodiment of the support device for the automatic tilting and turning platform provided by the present invention, an eyepiece is vertically inserted into the detection cylinder, with its bottom abutting against the positioning plate. A rubber sleeve connected to the detection cylinder is fitted onto the eyepiece, and a warning coating is applied to the outer ring of the eyepiece. A second proximity switch is installed on the inner wall of the detection cylinder, located above the positioning plate. The anti-bending detection module is signal-connected to the second proximity switch. By fitting a rubber sleeve around the outer ring of the eyepiece, the friction between the eyepiece and the detection cylinder is increased. Each time the positioning plate moves upward, the eyepiece moves upward and remains in its original position, allowing the operator to visually inspect it. By observing the distance the visual rod extends, the degree of spindle bending can be determined, allowing maintenance personnel to promptly detect spindle bending problems. When the spindle bending exceeds the standard, the warning layer on the visual rod will leak out from the detection cylinder, allowing maintenance personnel to visually identify the problem. When the positioning plate moves up and contacts proximity switch two, proximity switch two sends a position signal to the anti-bending detection module. The anti-bending detection module determines that the degree of spindle bending has reached the preset maximum bending degree, requiring timely handling by maintenance personnel. At this time, the anti-bending detection module issues a corresponding alarm signal to remind the staff to handle the problem promptly. The alarm signal can be a light or sound reminder.

[0014] In a preferred embodiment of the support device for the automatic tilting and turning platform provided by the present invention, the drive assembly includes a drive motor mounted on the support frame and a drive shaft rotatably connected to the support frame. The output end of the drive motor is connected to the drive shaft, and the drive shaft is linked to the main shaft via a chain. A conveying track is provided on the support frame, and a connecting track corresponding to the conveying track is provided on the tilting frame. A limit electromagnet corresponding to the mine car is installed on the tilting frame. The tilting auxiliary module is connected to the limit electromagnet and the drive motor respectively. The mine car moves along the conveying track and gradually moves to the connecting track. On the track, the mine car moves along the connecting track to the tilting frame. At this time, the tilting auxiliary module controls the limit electromagnet to magnetically fix the mine car. The mine car is made of iron and can be magnetically attracted by the limit electromagnet. When the tilting auxiliary module controls the drive component, it controls the corresponding drive motor to work. The drive motor drives the drive shaft to rotate forward or backward, thereby controlling the main shaft to rotate forward or backward through the chain. This controls the tilting frame to tilt or reset. By gradually controlling the tilting frame to tilt, the ore discharge state in the mine car is controlled. After the ore is tilted, the tilting frame is controlled to reset in time, reducing the ore tilting time and improving the tilting efficiency.

[0015] As a preferred embodiment of the tilting method of the support device for the automatic tilting and turning platform provided by the present invention, the method includes the following steps: S1, mine car transfer: the mine car carrying ore is moved to the tilting frame and is restrained on the tilting frame; S2, ore tilting: the drive component controls the main shaft to rotate, the rotation of the main shaft drives the tilting frame to tilt, and the tilting frame tilts to tilt the ore on the mine car; S3, tilting control: by detecting the displacement distance of the follower rod end by the distance sensor, the pressure of the main shaft on the detection half-set is determined, and the tilting state of the ore on the mine car is determined. After the mine car on the tilting frame has tilted and tilted, the pressure of the main shaft on the detection half-set decreases, the displacement distance data detected by the distance sensor decreases, it is determined that the ore tilting is completed, the drive component controls the tilting frame to reset, and the tilting is completed.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The support device for an automatic tilting and overturning platform provided by the present invention, when a mine car carrying ore is moved onto the tilting frame, the weight borne by the tilting frame increases, thereby driving the main shaft to move downward. The main shaft will press down on the detection half-sleeves at both ends, thereby squeezing the inner cavity of the detection half-sleeves. The compression of the inner cavity space of the detection half-sleeves will push the sealing plates at both ends to move. The sealing plate located at one end of the follower rod will push the follower rod to move. The distance sensor detects the distance between the end of the follower rod and the distance sensor. By detecting the displacement distance of the end of the follower rod by the distance sensor, the main shaft can be judged. The shaft detects the pressure of the half-set, and after the mine car on the tilting frame has tilted and finished tilting, the pressure on the half-set from the main shaft decreases. The sealing plate drives the follower rod to move down, and at this time, the displacement distance data detected by the distance sensor decreases. Therefore, the state of the ore on the mine car can be intuitively understood. During the tilting process of the mine car, the tilting status of the ore in the mine car can be understood in a timely manner. After the ore is detected to be tilted, the drive component is controlled to work in a timely manner to control the tilting frame to reset. This avoids the situation where each mine car needs to be tilted for a long time. The tilting time of each mine car can be flexibly adjusted to improve the tilting efficiency of the ore during automatic tilting.

[0017] 2. The present invention provides a support device for an automatic tilting and turning platform. By setting a tilting intelligent controller, the tilting detection module can automatically determine the tilting state of the ore. During the tilting process, the detection module sends an auxiliary signal to the tilting auxiliary module, which controls the vibration motor to work. The vibration motor vibrates, causing the tilting frame and the mine car to vibrate, assisting the ore to tilt along the inclined mine car. When it is determined that the ore in the mine car has been tilted, the tilting detection module sends a reset signal to the tilting auxiliary module. The tilting auxiliary module controls the vibration motor to stop working and controls the drive component to drive the tilting frame to reset. This realizes real-time detection of the tilting state of the ore in each mine car and automatically determines the tilting state. After the tilting is completed, the tilting frame is promptly controlled to reset, avoiding the need for each mine car to be tilted for a long time. It adapts and flexibly adjusts the tilting time of each mine car, improving the tilting efficiency of the ore during automatic tilting. Attached Figure Description

[0022] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the embodiments of the present invention can be combined with each other.

[0023] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0024] Example 1

[0025] Please refer to Figures 1-4. A support device for an automatic tilting and overturning platform includes: a support frame 1 and a tilting detection mechanism 8. A main shaft 7 is rotatably connected to the support frame 1, and a tilting frame 4 is fixed on the main shaft 7. The tilting frame 4 is used to tilt the mine car. A drive assembly for driving the main shaft 7 to rotate is installed on the support frame 1. A vibration motor 9 is installed on the tilting frame 4. When the mine car is full of ore, it moves to the tilting frame 4. At this time, the drive assembly drives the main shaft 7 to rotate. When the main shaft 7 rotates, it will drive the tilting frame 4 to tilt, thereby causing the mine car on the tilting frame 4 to tilt and tilt the ore to one side. During the tilting process, a device for fixing the mine car is set on the tilting frame 4 to prevent the mine car from slipping during the tilting process. By controlling the operation of the vibration motor 9, the tilting frame 4 and the mine car vibrate, thereby accelerating the tilting efficiency of the ore in the mine car.

[0026] Additionally, the flipping detection mechanism 8 is located at both ends of the main shaft 7 and is installed with the support frame 1. The flipping detection mechanism 8 includes a detection half-sleeve 13 located below the end of the main shaft 7 and abutting against its bottom surface, sealing plates 25 located at both ends of the inner cavity of the detection half-sleeve 13, and a follower rod 14 inserted into one end of the detection half-sleeve 13. At this time, the outer shell of the detection half-sleeve 13 is installed with the support frame 1, and the support frame 1 supports the main shaft 7 by bearing the load through the detection half-sleeve 13. The follower rod 14 extends to the detection half-sleeve 13. One end of the inner cavity of the half-set 13 abuts against the sealing plate 25. A distance sensor 15 is installed on the detection half-set 13, corresponding to the end of the follower rod 14 away from the sealing plate 25. By setting the flipping detection mechanism 8, when the mine car carrying ore is moved to the tilting frame 4, the weight borne by the tilting frame 4 increases, thereby driving the main shaft 7 to move downward. The main shaft 7 will press down on the detection half-set 13 at both ends, thereby squeezing the inner cavity of the detection half-set 13. The compression of the inner cavity space of the detection half-set 13 will push the sealing plate at both ends. When plate 25 moves, the sealing plate 25 located at one end of follower rod 14 will push follower rod 14 to move. By setting distance sensor 15, distance sensor 15 detects the distance between the end of follower rod 14 and distance sensor 15. By detecting the displacement distance of the end of follower rod 14, it is easy to judge the pressure of main shaft 7 on detection half-set 13. After the mine car on tilting frame 4 has tilted and dumped, the pressure of main shaft 7 on detection half-set 13 decreases, and sealing plate 25 drives follower rod 14 to move down. At this time, the displacement distance data detected by distance sensor 15 decreases. Therefore, the state of ore on mine car can be intuitively understood. During the control of mine car tilting, the tilting state of ore in mine car can be understood in time. After the ore is detected to be dumped, the drive component is controlled to work in time to control tilting frame 4 to reset. This avoids the state that each mine car needs to be tilted for a long time. The tilting time of each mine car can be adjusted flexibly and adaptably, improving the tilting efficiency of ore during automatic tilting.

[0027] It is worth mentioning that, as shown in Figure 5, the support device of the automatic tilting and overturning platform also includes a tilting intelligent controller 5. The tilting intelligent controller 5 is installed on the support frame 1. The tilting intelligent controller 5 is equipped with a tilting detection module and a tilting auxiliary module. The tilting detection module is connected to the distance sensor 15 and the tilting auxiliary module respectively. The tilting auxiliary module is connected to the drive assembly and the vibration motor 9 respectively. When the mine car moves onto the tilting frame 4, the tilting frame 4 is subjected to the pressure of the mine car, and its weight increases. The main shaft 7 generates a continuous pressure on the detection half-set 13. Under this state, the distance sensor 15 sends the detected distance data to the tilting detection module. The tilting auxiliary module controls the drive assembly to work. The drive assembly drives the main shaft 7 to rotate, controlling the mine car carrying the tilting frame 4 to gradually rotate. During this process, the tilting detection module compares the received distance data with the preset initial distance value (the tilting detection module presets the distance sensor 15 after the empty mine car moves onto the tilting frame 4). 5. By comparing the detected distance data, when the detected distance data is greater than the preset initial distance value, the tilting detection module sends an auxiliary signal to the tilting auxiliary module. The tilting auxiliary module controls the vibration motor 9 to work, and the vibration motor 9 vibrates to drive the tilting frame 4 and the mine car to vibrate, assisting the ore to tilt along the inclined mine car. When the tilting detection module determines that the distance data has dropped to the same as the preset initial distance value (the difference between the two data is less than the preset range), it is determined that the ore in the mine car has been tilted. At this time, the tilting detection module sends a reset signal to the tilting auxiliary module, and the tilting auxiliary module controls the vibration motor 9 to stop working and controls the drive component to drive the tilting frame 4 to reset. This realizes real-time monitoring of the ore tilting status in each mine car and automatically determines the tilting status. After the tilting is completed, the tilting frame 4 is promptly controlled to reset, avoiding the need for each mine car to tilt for a long time. The tilting time of each mine car can be flexibly adjusted, improving the ore tilting efficiency during automatic tilting.

[0028] In this embodiment, referring to Figure 6, the inner cavity of the detection half-set 13, located between the two sealing plates 25, is filled with hydraulic medium, preferably hydraulic oil. A pressure regulating pipe 16 is connected to the end of the detection half-set 13 furthest from the follower rod 14. A solenoid valve 17 is installed on the pressure regulating pipe 16. By setting the pressure regulating pipe 16, the pressure at the end of the detection half-set 13 can be increased, pushing the sealing plate 25 to move, thereby controlling the position of the other sealing plate 25 and the follower rod 14. The position of the follower rod 14 is detected by the distance sensor 15, and the position of the follower rod 14 is calibrated to improve the accuracy of the distance sensor. To improve the detection accuracy of distance sensor 15, bearings 12 are installed at the corresponding positions of the main shaft 7 and the detection half-sleeve 13. The outer ring of the main shaft 7 abuts against the outer ring of the bearing 12. The side wall of the detection half-sleeve 13 that abuts against the main shaft 7 is an elastic side wall. By setting bearings 12, the wear of the detection half-sleeve 13 by the main shaft 7 can be reduced, and the service life of the detection half-sleeve 13 can be improved. When the main shaft 7 presses the detection half-sleeve 13 through the bearing 12, the bearing 12 will press the elastic side wall on the detection half-sleeve 13, improving the sensitivity of the internal cavity space change of the detection half-sleeve 13 and flexibly controlling the displacement of the follower rod 14, which facilitates accurate detection by distance sensor 15.

[0029] Preferably, as shown in Figures 1 and 2, the drive assembly includes a drive motor 6 mounted on the support frame 1 and a drive shaft 11 rotatably connected to the support frame 1. The output end of the drive motor 6 is connected to the drive shaft 11. The drive shaft 11 is linked to the main shaft 7 via a chain. A conveying track 2 is provided on the support frame 1, and a connecting track 10 corresponding to the conveying track 2 is provided on the tilting frame 4. A limit electromagnet 3 corresponding to the mine car is installed on the tilting frame 4. The tilting auxiliary module is signal-connected to the limit electromagnet 3 and the drive motor 6 respectively. The mine car moves along the conveying track 2 and gradually moves to the connecting track 10. The mine car moves along the connecting track 10. When the mine car is moved onto the tilting frame 4, the tilting auxiliary module controls the limit electromagnet 3 to magnetically fix it. The mine car is made of iron and can be magnetically attracted by the limit electromagnet 3. When the tilting auxiliary module controls the drive component to work, it will control the corresponding drive motor 6 to work. The drive motor 6 drives the drive shaft 11 to rotate forward or backward, thereby controlling the main shaft 7 to rotate forward or backward through the chain, thereby controlling the tilting frame 4 to tilt or reset. By gradually controlling the tilting frame 4 to tilt, the state of ore discharge in the mine car is controlled. After the ore is tilted, the tilting frame 4 is controlled to reset in time, reducing the time of tilting ore and improving the tilting efficiency.

[0030] Example 2

[0031] The support device for the automatic tilting and overturning platform provided in Embodiment 1 is further optimized. Unlike the first embodiment, the weight of the mine car and ore is supported by the main shaft 7. When the weight of the ore loaded on the mine car is too large, it will put great pressure on the detection half-set 13, which may damage the detection half-set 13. To solve the above problem, please refer to Figure 4. A proximity switch 18 is installed above the top of the follower rod 14. An auxiliary top block 19 is abutted at the bottom of the end of the main shaft 7 near the overturning detection mechanism 8. A telescopic motor 20 is installed at the bottom of the auxiliary top block 19. The tilting intelligent controller 5 is also equipped with a load-bearing protection module. The load-bearing protection module is connected to the proximity switch 18. Switch 18 and telescopic motor 20 are connected by a signal. When the main shaft 7 presses the detection half-sleeve 13, the follower rod 14 will gradually move upward. When the follower rod 14 moves upward and contacts the proximity switch 18, the proximity switch 18 sends a position signal to the load-bearing protection module. The load-bearing protection module determines that the pressure on the main shaft 7 exceeds the limit and starts the protection mode. The load-bearing protection module controls the telescopic motor 20 to work. The telescopic motor 20 pushes the auxiliary top block 19 to move upward to support the main shaft 7, reduce the pressure of the main shaft 7 on the detection half-sleeve 13, and protect the detection half-sleeve 13 so that it is not easily damaged by the large weight of the ore.

[0032] Example 3

[0033] The support device for the automatic tilting and turning platform provided in Embodiment 1 is further optimized. Unlike the first embodiment, when the tilting frame 4 is driven to tilt by the main shaft 7, the main shaft 7 will bend with the increase of usage time. At this time, the middle of the main shaft 7 is concave and the two ends are raised. After long-term use, the wear of the equipment will gradually increase, affecting the tilting operation of the tilting frame 4 and posing certain safety hazards. In order to solve the above problems, please refer to Figures 4, 5 and 7. Each end of the main shaft 7 is provided with an anti-bending detection mechanism. The anti-bending detection mechanism includes a centering rod 21 inserted into the center of the end of the main shaft 7, a detection cylinder 23 connected to the support frame 1, and a transmission rod 22 vertically inserted into the top of the detection cylinder 23. The top of the transmission rod 22 is sleeved with the end of the centering rod 21. The inner cavity of the detection cylinder 23 is vertically slidably connected to a positioning plate 26 fixed to the bottom end of the transmission rod 22. The bottom of the inner cavity of the detection cylinder 23 is installed with a corresponding positioning plate 26. The distance sensor 27 and the tilting controller 5 are equipped with an anti-bending detection module. The anti-bending detection module is connected to the proximity switch 18 and the telescopic motor 20. When the main shaft 7 bends, the centers at both ends of the main shaft 7 will jump during the rotation of the main shaft 7, thereby causing the centering rod 21 connected to the center of the main shaft 7 to jump. This causes the transmission rod 22 to drive the positioning plate 26 to move vertically in the inner cavity of the detection cylinder 23. At this time, the distance sensor 27 will detect the distance data of the positioning plate 26 in real time and send it to the anti-bending detection module. The anti-bending detection module will compare the received distance data with the preset distance threshold (the anti-bending detection module has a preset maximum distance between the distance sensor 27 and the positioning plate 26 when the main shaft 7 bends excessively). When it is determined that the distance data exceeds the distance threshold, the main shaft 7 bends significantly. The anti-bending detection module will issue a corresponding reminder signal to remind the staff to handle the situation in time. The reminder signal can be a light or sound reminder.

[0034] It is worth mentioning that a visual rod 24 is vertically inserted into the detection cylinder 23, with its bottom abutting against the positioning plate 26. A rubber sleeve connected to the detection cylinder 23 is fitted onto the visual rod 24, and a warning coating is applied to the outer ring of the visual rod 24. The rubber sleeve on the outer ring of the visual rod 24 increases the friction between the visual rod 24 and the detection cylinder 23. Each time the positioning plate 26 moves upward, it can move the visual rod 24 upward and maintain its original position. Therefore, operators can visually judge the degree of spindle 7 distortion by observing the distance the visual rod 24 extends, facilitating timely detection of spindle 7 bending problems by maintenance personnel. Furthermore, when the spindle 7 bending exceeds the standard, the visual rod... The warning layer on 24 will leak out from the detection cylinder 23, allowing maintenance personnel to visually identify problems. The inner wall of the detection cylinder 23 is equipped with a proximity switch 28 located above the positioning plate 26. The anti-bending detection module is connected to the proximity switch 28. When the positioning plate 26 moves upward and contacts the proximity switch 28, the proximity switch 28 sends a position signal to the anti-bending detection module. The anti-bending detection module determines that the bending degree of the spindle 7 has reached the preset maximum bending degree, requiring maintenance personnel to handle it in time. At this time, the anti-bending detection module issues a corresponding alarm signal to remind the staff to handle it in time. The alarm signal can be a light or sound reminder.

[0035] A tilting method for an automatic tilting and overturning platform support device includes the following steps: S1, mine car transfer: the mine car carrying ore moves to the tilting frame 4 and is restrained on the tilting frame 4; S2, ore tilting: the drive component controls the main shaft 7 to rotate, the rotation of the main shaft 7 drives the tilting frame 4 to tilt, and the tilting frame 4 tilts to tilt the ore on the mine car; S3, tilting control: the displacement distance of the follower rod 14 is detected by the distance sensor 15 to determine the pressure of the main shaft 7 on the detection half-set 13, and to determine the tilting state of the ore on the mine car. After the mine car on the tilting frame 4 has tilted and tilted completely, the pressure of the main shaft 7 on the detection half-set 13 decreases, the displacement distance data detected by the distance sensor 15 decreases, and it is determined that the ore tilting is completed. The drive component controls the tilting frame 4 to reset, completing the tilting.
