Description

Technical Field

[0001] This invention relates to the field of mining equipment technology, specifically to an automatic suspended intelligent conveying device for mining ore. Background Technology

[0002] In mining operations, ore conveying is a core link connecting mining and subsequent processing, and its efficiency and stability directly affect overall mining productivity. Currently, the ore conveying equipment widely used in the mining industry is mainly traditional belt conveyors. This type of equipment uses motor-driven rollers to move the belt to transport ore. It has a simple structure and low cost, and is widely used in various mining scenarios. However, with the expansion of mining scale and the diversification of ore types, traditional equipment has gradually revealed obvious shortcomings and is unable to meet the efficient and stable conveying requirements of modern mines.

[0003] Traditional belt conveyors typically employ a fixed, rigid support structure, lacking flexible buffering and adjustment capabilities. When ore is dumped in concentrated areas or its weight fluctuates during transport, significant deformation can easily occur in the middle of the belt. This not only leads to insufficient stability during ore transport, making slippage and rolling more likely, but also exacerbates belt wear due to excessive localized stress, shortening the equipment's lifespan. Furthermore, the support force of existing equipment is mostly a fixed value, unable to be flexibly adjusted according to the different weights and hardnesses of the ore. When dealing with various ore transport scenarios, frequent shutdowns are required to replace parts or adjust equipment parameters, severely impacting transport efficiency and increasing manual maintenance costs.

[0004] Furthermore, the complex working environment in mines makes belt conveyors prone to belt misalignment during long-term operation due to uneven ore distribution, equipment vibration, or uneven ground. Currently, the primary method for resolving belt misalignment is manual inspection and adjustment, which is not only labor-intensive and slow to respond, but also susceptible to human error leading to untimely correction, causing belt wear, equipment jamming, or even shutdown. The few devices with automatic correction functions suffer from complex structures, low correction accuracy, and poor adaptability, making them unsuitable for the harsh working environment of mines and hindering the achievement of accurate and efficient automatic correction, thus restricting the intelligent upgrading of the mining conveying process. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides an automatic suspended intelligent conveying device for mining ore, which solves the problems of insufficient support and buffering, inability of support force to adapt to different ores, and the need for manual correction of belt deviation in traditional ore conveying equipment, thereby improving the conveying stability, adaptability, and level of intelligence.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an automatic suspended intelligent conveying device for mining ore, comprising a frame, a first roller movably mounted on one side of the frame via a bearing mounting seat, and a second roller movably mounted on the other side of the frame via a bearing mounting seat.

Both ends of the support platforms are movably installed at the inner bottom of the horizontal frame via guide rails, and the top of each support platform abuts against the lower surface of the corresponding side spring plate.

[0010] Preferably, an adjustment motor is fixedly installed on one side of the inner side of the frame, a long shaft is fixedly installed on the drive end of the adjustment motor, worm gears are fixedly installed on the outer diameter of the middle part of the horizontal shaft, and worms are fixedly installed on the outer diameter of the long shaft at positions corresponding to each worm gear, with the inner ends of the worm gears and worms on the corresponding sides meshing and connected.

[0014] This invention provides an automatic overhead intelligent conveying device for mining ore. It has the following advantages:

[0015] 1. This invention uses a spring plate and a pressure roller to automatically compensate for changes in elasticity, ensuring that the support force of the support roller on the conveyor belt remains stable. This avoids excessive belt deformation caused by fluctuations in ore weight. The support roller is buffered by linkage between the connecting rod and the rotating frame, reducing damage to the conveyor belt from ore impacts. At the same time, it ensures the friction between the belt and the support roller, preventing slippage and improving transportation reliability.

[0016] 2. By adjusting the structure of the motor-driven worm gear, worm wheel, and threaded rod, the position of the support platform can be flexibly adjusted, and the elasticity of the spring plate and the supporting force of the support roller can be changed to adapt to the transportation of ores of different weights and types. The working conditions can be switched without major modifications to the equipment, thus improving the versatility and flexibility of the equipment.

[0017] 3. The visual sensor of this invention monitors the conveyor belt deviation in real time, and works with hydraulic cylinders, correction rollers and other structures to achieve automatic correction without manual adjustment, reducing manpower input. During the correction process, the movable sleeve achieves longitudinal displacement through the cooperation of limit pins and inclined grooves, ensuring accurate and efficient correction and avoiding transportation failures or equipment damage caused by belt deviation.

Detailed Implementation

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Example:

[0027] Please see the appendix Figure 1 -Appendix Figure 6 This invention provides an intelligent automatic suspended conveying device for mining ore, such as... Figure 1As shown, the system includes a frame 1, which serves as the core mounting foundation for the entire conveying equipment. Frame 1 provides a stable support for all subsequent functional components, ensuring that each component maintains a stable relative position during ore transportation and preventing overall structural displacement due to equipment vibration or ore impact. This is the fundamental guarantee for stable ore transportation. A first roller 2 is movably mounted on one side of the frame 1 via a bearing mounting seat. The first roller 2 serves as the active drive roller for the conveyor belt 4. Through a fixed connection with the driven sprocket 9, it can rotate under the drive of the transmission chain 10, thereby providing power for the movement of the conveyor belt 4 and ensuring that the conveyor belt 4 can stably transport the ore. A second roller 3 is movably mounted on the other side of the frame 1 via a bearing mounting seat. The second roller 3 serves as the driven reversing roller for the conveyor belt 4. The conveyor belt 4, in conjunction with the first roller 2, forms a closed transmission loop, ensuring that the conveyor belt 4 can move smoothly in a circular motion. At the same time, it tensions and guides the end of the conveyor belt 4, preventing the belt from becoming loose or deviating at the end. The outer diameters of the first roller 2 and the second roller 3 are connected by the conveyor belt 4. The conveyor belt 4 is the direct load-bearing component for ore transportation. The movement of its surface can directly drive the ore placed on it to achieve displacement, completing the ore transportation operation at the mining site. The surface of the conveyor belt 4 is uniformly provided with several herringbone patterns 5. The herringbone patterns 5 can effectively increase the friction between the surface of the conveyor belt 4 and the ore, preventing the ore from slipping or rolling off during transportation due to equipment vibration, belt tilting, or acceleration and deceleration, further improving the stability and safety of ore transportation.

[0028] In this embodiment, several transverse fixing plates 11 are uniformly fixed inside the frame 1. These transverse fixing plates 11 are horizontally fixed inside the frame 1, providing a stable mounting platform for the support structures such as the uprights 12 and crossbars 14. Through a uniformly distributed design, the weight of the ore and the pressure of the conveyor belt 4 can be evenly distributed throughout the frame 1, preventing excessive local stress that could lead to structural damage. Uprights 12 are fixedly installed on both sides of the top of the transverse fixing plates 11. The uprights 12 are vertically fixed to the top of the transverse fixing plates 11, and their tops provide a fulcrum for the movable installation of the support rollers 13, ensuring that the support rollers 13 can rotate flexibly. Simultaneously, the uprights 12 themselves possess sufficient structural strength to withstand the ore pressure and belt tension transmitted by the support rollers 13. The tops of the uprights 12 are all movable. A support roller 13 is installed, which directly abuts against the lower surface of the conveyor belt 4, providing real-time support for the conveyor belt 4. When the conveyor belt 4 deforms due to the weight of the ore, the support roller 13 can adapt to the belt's movement by rotating itself. Simultaneously, one end of the support roller 13 can rotate and descend around the top of the upright 12, thereby activating the subsequent buffer structure via the connecting rod 18, achieving buffering and compensation for belt deformation. Two crossbeams 14 are also fixedly installed at the top of the transverse fixing plate 11. The crossbeams 14 are symmetrically fixed at the center of the top of the transverse fixing plate 11, providing installation space and support foundation for buffer adjustment components such as the rotating frame 15 and the spring plate 16. Their internal installation structure ensures that the spring plate 16 can be stably fixed without affecting the movement of the rotating frame 15. The crossbeams 14... A rotating frame 15 is movably mounted on each outer end. The rotating frame 15 serves as a transmission connector between the connecting rod 18 and the spring plate 16. Driven by the connecting rod 18, it can bend and rotate around the outer end of the cross frame 14, thereby converting the downward displacement of the support roller 13 into pressure on the spring plate 16. Simultaneously, it can transmit the elastic force of the spring plate 16 in the opposite direction to the connecting rod 18 and the support roller 13, achieving bidirectional transmission of buffering force. Spring plates 16 are fixedly installed inside each cross frame 14, with the ends of the spring plates 16 extending into the interior of the corresponding rotating frame 15. The spring plate 16 is the core elastic component of the equipment's buffering function, possessing excellent elastic deformation capability. When subjected to pressure transmitted by the rotating frame 15 through the pressure roller 17, it undergoes bending deformation, simultaneously generating a reverse elastic force. This elastic force can... The rotation frame 15 and connecting rod 18 transmit the energy to the support roller 13, providing stable support for the deformed parts of the conveyor belt 4. At the same time, its elasticity can effectively absorb the kinetic energy generated by the impact of the ore, reducing damage to the conveyor belt 4 and the equipment structure. The top of the rotation frame 15 is movably mounted with a connecting rod 18, and the end of the connecting rod 18 is movably mounted at the end of the corresponding side support roller 13. As the transmission medium between the support roller 13 and the rotation frame 15, the connecting rod 18 can accurately transmit the rotational downward displacement of the support roller 13 caused by the belt deformation to the rotation frame 15, ensuring that the rotation frame 15 can respond to the belt deformation in a timely manner. At the same time, the spring force transmitted by the rotation frame 15 is reversed and applied to the support roller 13, so that the support roller 13 always maintains a stable support force for the conveyor belt 4.

[0029] Furthermore, a motor mounting bracket 6 is fixedly installed on the top of the frame 1 near the first roller 2. The motor mounting bracket 6 provides a stable mounting position for the geared motor 7. Its structural design can effectively absorb the vibration generated by the geared motor 7 during operation, preventing the vibration from being transmitted to the frame 1 and causing other parts to loosen, thus ensuring the stable operation of the geared motor 7. The geared motor 7 is fixedly installed on the top of the motor mounting bracket 6. As the power source of the entire equipment, the output speed of the geared motor 7 is more stable after being reduced, which can provide a stable driving force for the drive sprocket 8, avoiding uneven movement speed of the conveyor belt 4 due to speed fluctuations, and thus preventing the ore from slipping on the belt. The drive end of the geared motor 7 is fixedly installed with the drive sprocket 8. The drive sprocket 8 is fixedly connected to the drive end of the geared motor 7, which can convert the torque of the geared motor 7 into a transmission chain. The tension of the drive sprocket 10 is transmitted to the driven sprocket 9 via chain drive. Its gear structure design ensures stable meshing transmission with the drive chain 10, avoiding chain skipping or derailment. The driven sprocket 9 is fixedly installed at one end of the first roller 2. The driven sprocket 9 is fixed to the first roller 2 as a whole, which can directly convert the power transmitted by the drive chain 10 into the rotational torque of the first roller 2, driving the first roller 2 to rotate synchronously, thereby realizing the power drive of the conveyor belt 4. The outer diameters of the drive sprocket 8 and the driven sprocket 9 are connected by the drive chain 10. The drive chain 10 serves as the power transmission medium, connecting the drive sprocket 8 and the driven sprocket 9, and efficiently transmitting the power of the geared motor 7 to the first roller 2. It has high transmission efficiency and strong load-bearing capacity, and can adapt to the harsh working conditions of the mining site, ensuring the stability and reliability of power transmission.

[0030] Furthermore, pressure rollers 17 are fixedly installed on the inner top and inner side of the rotating frame 15, and the bottom ends of the pressure rollers 17 abut against the upper surface of the corresponding side spring plate 16. The pressure rollers 17 are fixed to the inner top of the rotating frame 15. When the rotating frame 15 bends and rotates, the pressure rollers 17 will move synchronously with the rotating frame 15, thereby applying downward pressure to the spring plate 16, causing the spring plate 16 to undergo elastic deformation. At the same time, the pressure rollers 17 can roll on the surface of the spring plate 16, realizing positional displacement during the bending of the spring plate 16. This displacement can compensate for the increase in elastic force generated by the increased bending degree of the spring plate 16, ensuring that the elastic force generated by the spring plate 16 remains stable, thereby providing continuous and stable support force for the support roller 13 and avoiding unstable support of the conveyor belt 4 due to elastic force fluctuations.

[0031] Furthermore, a horizontal shaft 19 is movably installed at the top center of each horizontal fixed plate 11. The horizontal shaft 19 passes horizontally through the top center of the horizontal fixed plate 11, and its two ends extend into the interior of the two side cross frames 14 and are fixedly connected to the threaded rod 20. It can achieve synchronous rotation under the drive of the worm gear 24, thereby providing power for the rotation of the threaded rod 20. At the same time, its movable installation method ensures smooth rotation and will not affect the adjustment accuracy due to jamming. The two ends of the horizontal shaft 19 extend into the inner bottom of the two side cross frames 14 and are fixedly installed with the threaded rod 20. The threaded rod 20 is fixedly connected to the horizontal shaft 19 and can rotate synchronously with the horizontal shaft 19. Its external thread structure cooperates with the internal thread of the support platform 21, which can convert its own rotational motion into the linear motion of the support platform 21, thereby realizing the adjustment of the position of the support platform 21. The outer diameter of the threaded rod 20 is threaded with the support platform 21, and the support platform 21 is connected by... The guide rail is movably installed at the bottom of the cross frame 14 and can move synchronously inward or outward under the drive of the threaded rod 20. Its top end abuts against the lower surface of the spring plate 16. By changing its own position, the support point of the spring plate 16 can be adjusted, thereby changing the magnitude of the elastic force generated when the spring plate 16 bends, so as to adapt to the transportation needs of different weights and types of ores. Both ends of the support platform 21 are movably installed at the bottom of the cross frame 14 through the guide rail, and the top end of the support platform 21 abuts against the lower surface of the corresponding side spring plate 16. The guide rail provides guidance and limit for the movement of the support platform 21, ensuring that the support platform 21 can only move in a straight line in the lateral direction under the drive of the threaded rod 20, avoiding deviation or jamming. At the same time, the abutting connection between the top end of the support platform 21 and the spring plate 16 ensures that the support point of the spring plate 16 can be accurately changed when the position of the support platform is adjusted, so as to achieve precise adjustment of the elastic force.

[0032] Furthermore, an adjusting motor 22 is fixedly installed on one side of the inside of the frame 1. The adjusting motor 22 serves as the power source for the support force adjustment system, outputting stable rotational power according to different ore transportation needs. By driving the long shaft 23 to rotate, it drives subsequent transmission components such as worm gears 25 and worm wheels 24, achieving automatic adjustment of the support platform 21 position without manual intervention, thus enhancing the equipment's intelligence. The driving end of the adjusting motor 22 is fixedly installed with the long shaft 23, which is horizontally installed inside the frame 1. Multiple worm gears 25 are fixed on its outer diameter, allowing it to rotate as a whole under the drive of the adjusting motor 22. This drives all worm gears 25 to rotate synchronously, ensuring that the support platforms 21 on the multiple horizontal fixed plates 11 can achieve synchronous adjustment and guaranteeing uniform overall support force on the conveyor belt 4. Worm wheels 24 are fixedly installed on the outer diameter of the middle part of the horizontal shaft 19, and are fixedly connected to the horizontal shaft 19, transmitting power through meshing with the worm gears 25. The rotational power of the worm 25 can be converted into the rotational power of the horizontal shaft 19. Its worm gear transmission structure has a self-locking function, which can keep the position of the support platform 21 stable after adjustment and avoid the support point from shifting due to external force. A worm 25 is fixedly installed on the outer diameter of the long shaft 23 at the position corresponding to each worm wheel 24. The worm 25 is fixedly connected to the long shaft 23 and rotates synchronously with the long shaft 23. Through the meshing with the worm wheel 24, the rotational power of the long shaft 23 is transmitted to each horizontal shaft 19, realizing the synchronous rotation of multiple horizontal shafts 19. The inner ends of the corresponding worm wheel 24 and worm 25 are meshed. The meshing connection between the worm wheel 24 and worm 25 is the core link of the adjustment power transmission. Its meshing transmission has high precision and can ensure that the power of the adjustment motor 22 is efficiently transmitted to the horizontal shaft 19. At the same time, through the deceleration characteristics of the worm gear, the position adjustment accuracy of the support platform 21 is improved, ensuring more precise elastic adjustment.

[0033] Furthermore, a mounting plate 26 is fixedly installed at the bottom of the frame 1. The mounting plate 26 is fixed to the bottom of the frame 1, providing a stable mounting foundation for the correction components such as the support base 27 and the hydraulic cylinder 32. Its structural strength can withstand the force generated during the correction process, preventing the components from loosening due to the correction movement and ensuring the stable operation of the correction system. The support base 27 is movably installed at the top center of the mounting plate 26. The support base 27 is movably installed at the top of the mounting plate 26 and can deflect around the mounting point at the top of the mounting plate 26 under the force applied by the hydraulic cylinder 32 through the extension frame 31. This deflects the fixed upright 28, the movable sleeve 29, and the correction roller 30 synchronously, providing a basis for the angle adjustment of the correction roller 30. Fixed uprights 28 are fixedly installed on both sides of the top of the support base 27. The fixed uprights 28 are vertically fixed to the top of the support base 27, providing a longitudinal movable mounting carrier for the movable sleeve 29. The internal guides The structure ensures that the movable sleeve 29 can slide smoothly in the longitudinal direction, while also limiting the movable sleeve 29 to prevent lateral deviation during the correction process. The movable sleeve 29 is movably installed on the top of the fixed frame 28. The movable sleeve 29 is fitted on the top of the fixed frame 28 and can move longitudinally along the fixed frame 28. The correction roller 30 installed on its inner end can be height adjusted by the movable sleeve 29, and can also be angled by following the deflection of the support 27, thereby achieving precise correction of the conveyor belt 4. The correction roller 30 is movably installed in the middle of the inner end of the movable sleeve 29. The correction roller 30 directly abuts against the two sides of the conveyor belt 4. Through its own angle deflection and height adjustment, it applies a lateral correction force to the deviated conveyor belt 4, pushing the conveyor belt 4 back to the correct transport track. Its movable installation method ensures that it can adapt to the movement of the conveyor belt 4 and avoids wear on the belt surface.

[0034] Furthermore, an extension frame 31 is fixedly installed on one side of the middle of the support base 27. The extension frame 31 serves as a transmission connector between the hydraulic cylinder 32 and the support base 27, converting the extension and retraction of the piston rod of the hydraulic cylinder 32 into a torque that drives the support base 27 to deflect. Its length design ensures that the driving force of the hydraulic cylinder 32 can be effectively amplified, enabling the support base 27 to deflect flexibly. The hydraulic cylinder 32 is movably installed on one side of the mounting plate 26, and the driving end of the hydraulic cylinder 32 is movably installed at the end of the extension frame 31. The hydraulic cylinder 32 serves as the power source of the correction system. By controlling the extension and retraction of the internal piston rod, it provides a linear driving force to the extension frame 31, thereby driving the support base 27 to deflect. It has a fast response speed and stable driving force, and can take timely action based on the detection signal of the vision sensor 36, ensuring the timeliness and effectiveness of the correction.

[0035] Furthermore, adjusting plates 33 are fixedly installed on both sides of the bottom end of the frame 1. The adjusting plates 33 are fixed on both sides of the bottom end of the frame 1, and the inclined grooves 34 provided by the adjusting plates provide the movement trajectory for the limit pins 35. Through the inclined angle design of the inclined grooves 34, the deflection movement of the support 27 is converted into the longitudinal displacement of the movable sleeve 29. This is a key component for realizing the height adjustment of the straightening roller 30. The middle part of the adjusting plates 33 is provided with inclined grooves 34, which provide a guide channel for the sliding of the limit pins 35. Its inclined structure allows the limit pins 35 to slide along the inclined grooves 34 when following the deflection of the support 27, and drive the movable sleeve 29 to move longitudinally along the fixed frame 28, thereby realizing the height adjustment of the straightening roller 30 and ensuring that the straightening roller 30 can apply a precise straightening force to the conveyor belt 4. The outer ends of the movable sleeve 29 are fixedly installed with Limiting pins 35 are movably disposed inside the corresponding side inclined grooves 34. The limiting pins 35 are fixed to the outer end of the movable sleeve 29, and their ends are embedded in the inclined grooves 34, serving to connect the movable sleeve 29 and the adjusting plate 33. They can transmit the guiding motion of the inclined grooves 34 to the movable sleeve 29, and at the same time limit the movement of the movable sleeve 29 to prevent excessive displacement of the movable sleeve 29. Vision sensors 36 are fixedly installed on the upper inner side of the movable sleeve 29. As a detection component of the correction system, the vision sensors 36 can capture the edge position of the conveyor belt 4 in real time, accurately identify whether the belt has deviated and the direction of deviation, and transmit the detection signal to the control system to provide a basis for the action of the hydraulic cylinder 32, ensuring that the correction system can achieve automated and precise correction control.

[0036] Working principle:

[0037] The ore to be transported is poured onto the surface of the conveyor belt 4. Then, the reduction motor 7 is started, driving the drive sprocket 8 to rotate. Through the transmission chain 10, the driven sprocket 9 and the first roller 2 rotate, thereby driving the second roller 3 to rotate and the conveyor belt 4 to move, transporting the ore. When the ore is poured onto the conveyor belt 4 and during transport, the middle of the conveyor belt 4 deforms, causing one end of the support roller 13 to rotate and descend. When one end of the support roller 13 descends, it causes one end of the rotating frame 15 to bend via the connecting rod 18. When the rotating frame 15 bends, it presses the spring plate 16 through the pressure roller 17, causing the spring plate 16 to bend further. The elastic force generated is reversed through the rotating frame 15 and connecting rod 18 to support the support roller 13, thereby providing stable support and buffering for the deformed parts of the conveyor belt 4, improving transmission stability. Simultaneously, during the bending of the spring plate 16, the pressure roller 17 shifts position on the surface of the spring plate 16, compensating for the increasing elastic force as the bending degree of the spring plate 16 increases. This keeps the spring plate 16 stable, ensuring that the support roller 13 always provides stable support for the conveyor belt 4, maintaining friction between the conveyor belt 4 and the support roller 13. This allows the conveyor belt 4 to transport normally while maintaining stable buffering force, reducing the impact of ore weight on the conveyor belt. The damage to the conveyor belt 4 caused by changes can also be mitigated by adjusting the motor 22 to drive the long shaft 23 to rotate, which in turn drives all the worm gears 25 to rotate. The rotating worm gears 25 will drive all the worm wheels 24 and the horizontal shaft 19 to rotate, thereby driving the threaded rod 20 to rotate. When the threaded rod 20 rotates, it will drive the support platforms 21 on both sides to move inward or outward synchronously. By adjusting the position of the support platform 21, the support point of the spring plate 16 is changed, thereby changing the elastic force generated when the spring plate 16 bends, and thus changing the support force of the support roller 13 on the conveyor belt 4, which can meet the transportation needs of different types of ore. When the conveyor belt 4 deviates due to uneven ore distribution or vibration, the vision sensor 36 will detect the deviation of the conveyor belt. When the conveyor belt 4 deviates in the direction of the deviation, the hydraulic cylinder 32 will control the internal piston rod to extend and retract. Then, through the transmission of the extension frame 31, the support seat 27 will be deflected, thereby causing the two correction rollers 30 to deflect. When the correction rollers 30 deflect, the limiting pin 35 at the outer end of the movable sleeve 29 will slide in the inclined groove 34, causing the movable sleeve 29 to move longitudinally on the fixed stand 28, thereby causing the correction rollers 30 to follow the movement. For example, when the conveyor belt 4 deviates to the left, the left correction roller 30 will rise and the right correction roller 30 will fall, correcting and aligning the position of the conveyor belt 4 until the positions of both sides of the conveyor belt 4 detected by the vision sensor 36 are the same, thus completing the automatic correction work.
