Rotatable tracks are installed on both sides of the base plate, and a detector for detecting the iron ore mine roof is detachably installed on the top of the base plate.

Description

Technical Field

[0001] This invention belongs to the field of iron ore mine roof safety detection technology, specifically a tracked adaptive iron ore mine roof safety detection device. Background Technology

[0002] In underground iron ore mining, geological disasters such as roof collapse and fall are major sources of risk threatening the lives of workers and causing significant economic losses. According to industry statistics, safety accidents caused by mine ground pressure disasters consistently account for a high percentage. As iron ore mining depths increase, the geological conditions in mining areas become increasingly complex. Factors such as high ground stress, karst development, and aquifer distribution further exacerbate the risk of roof instability, placing higher demands on the accuracy, real-time performance, and environmental adaptability of roof safety monitoring technology.

[0003] Early mine roof monitoring relied mainly on manual inspections combined with mechanical instruments (such as mechanical roof settling meters). This not only resulted in low data acquisition efficiency and large errors, but also required workers to enter high-risk mining areas, facing safety risks such as roof collapses and excessive levels of toxic and harmful gases. Even with the introduction of automated monitoring equipment in some mines, manual assistance was still needed to deploy sensors or move the equipment, making unmanned autonomous monitoring impossible and compromising monitoring timeliness and safety.

[0004] In order to improve the efficiency of data acquisition, reduce data acquisition errors and risks, existing technologies generally use tracked roof detection equipment to detect mine roofs in real time. However, tracked roof detection equipment inevitably encounters iron ore fragments of different sizes when moving. These iron ore fragments can hinder the movement of the tracked roof detection equipment. When the tracked roof detection equipment passes through, it may cause it to overturn or block its progress. On-site personnel need to enter the mine tunnel in time to clear the fragments. When personnel stay in the area where the equipment is stuck to clear the fragments, the area itself may have roof instability problems (the equipment is often close to high-risk areas for detection), and fragments may fall and injure the personnel.

[0005] Therefore, the present invention provides a tracked adaptive iron ore mine roof safety detection device. Summary of the Invention

[0006] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0007] The technical solution adopted by the present invention to solve its technical problem is as follows: The present invention provides a tracked adaptive iron ore mine roof safety detection device, including a base plate and a walking track. The base plate is equipped with self-rotating tracks on both sides, and a detector for detecting the iron ore mine roof is detachably installed on the top of the base plate. The base plate is provided with an adjustment component, which can change the distance between the two tracks, thereby effectively increasing the lateral support distance of the tracks on the base plate, lowering the center of gravity, and improving the anti-overturning ability of the base plate when traveling on complex terrain. The crossing element, located on top of the base plate, allows the base plate to fly within the mine tunnel, thus crossing larger boulders.

[0008] The adjusting components include rack plates and drive gears. Two drive gears are rotatably mounted inside the base plate. Rack plates that engage with each other are slidably mounted on the top and bottom of the two drive gears. The ends of multiple rack plates extending outside the base plate are slidably connected to the drive device of the track. The base plate has a chamber for the movement of the rack plates and the rotation of the drive gears.

[0009] A drive rod is rotatably mounted inside the base plate. Both ends of the drive rod are fixedly connected to the adjacent ends of two drive gears. A drive motor is fixedly mounted on the top of the base plate. Drive wheels are fixedly sleeved on both the power output end of the drive motor and the outside of the drive rod. The two drive wheels are rotatably connected by a tension belt.

[0010] Guide plates are fixedly installed on the outer walls of multiple rack plates, and guide rails for limiting the sliding trajectory of the guide plates are fixedly installed on the inner walls of the chamber.

[0011] The adjusting components also include upright blocks and support frames. Upright blocks are fixedly installed at one end of multiple rack plates extending to the outside of the base plate. Guide blocks are fixedly installed on the outside of the drive equipment of the two tracks. Guide grooves adapted to the guide blocks are opened at the ends of multiple upright blocks away from the rack plates. Support frames are fixedly installed on the top of the base plate. Directional guide rails are symmetrically slidably installed on both sides of the bottom of the support frame. Sliding blocks are symmetrically slidably installed in the inner cavities of the two directional guide rails. Hinges are rotatably installed at the ends of multiple sliding blocks extending to the outside of the directional guide rails via a rotating shaft. The ends of multiple hinges away from the sliding blocks are rotatably connected to the outer walls of the drive equipment of the two tracks respectively. A directional rod is fixedly installed in the inner cavity of each of the two directional guide rails. The outer wall of the sliding block has a through hole that matches the directional rod. Two return springs that match the sliding block are symmetrically fixedly sleeved on the outer wall of the directional rod.

[0012] The bottom of the detector and the top of the support frame are detachably connected, and a camera for providing a field of view of the track movement direction is fixedly installed on the top of the support frame.

[0013] The crossover component includes wings and rotating shafts. Two rotating shafts are symmetrically installed on both sides of the inner cavity of the support frame. Support plates are fixedly installed on the outer walls of multiple rotating shafts. Wings are rotatably installed on the top of the end of multiple support plates away from the rotating shafts. Brushless motors for wing rotation are fixedly installed on the bottom of the end of multiple support plates away from the rotating shafts. Protective covers for wing protection are fixedly installed on the top of multiple support plates. Storage slots for rotating support plates are symmetrically opened on both sides of the support frame.

[0014] Multiple rotating shafts have transmission gears fixedly sleeved on their outer walls. Two U-shaped plates are symmetrically slidably installed in the inner cavity of the support frame. Multiple locking teeth that engage with the transmission gears are fixedly installed on both sides of the two U-shaped plates. Threaded holes are opened on the top of the two U-shaped plates. A bidirectional threaded rod for synchronous sliding of the two U-shaped plates is rotatably installed between the two threaded holes. A transmission motor is fixedly installed on the top of the support frame. Transmission wheels are fixedly sleeved on the power output end of the transmission motor and one end of the bidirectional threaded rod. The two transmission wheels are rotatably connected by a transmission belt.

[0015] Guide holes are provided at the top of both U-shaped plates, and limiting rods for limiting their own movement trajectory are fixedly installed at the top of both U-shaped plates. The two ends of the limiting rods pass through the guide holes and are fixedly connected to the outer wall of the support frame.

[0016] The beneficial effects of this invention are as follows: 1. The adjustable parts can be used to make the front of one or both tracks have gravel higher than their own height, and can change the distance between the two tracks so that the two tracks can avoid the gravel and continue to move. This eliminates the need for on-site personnel to enter the mine tunnel to clear the gravel, and avoids the risk of falling gravel or slag injuring personnel when using the equipment to monitor the roof of the mine tunnel.

[0017] 2. When the track travels on the surface of slag or gravel, the vibration generated by the track is transmitted to the articulated rod. At this time, both ends of the articulated rod rotate simultaneously, thereby pushing the sliding block located in the directional guide rail to move repeatedly. When the sliding block moves repeatedly in the inner cavity of the directional guide rail, the sliding block will repeatedly squeeze the return spring, thereby absorbing the vibration generated by the track. This can achieve the effect of vibration reduction of the track, filter road vibration, reduce track tilting and bouncing, and improve the anti-tipping ability of the equipment on slopes and rugged roads.

[0018] 3. The traversing component provides lift to the equipment, enabling it to continue moving forward in relatively wide mine tunnels when encountering slag or gravel larger than itself, until it crosses the larger pieces of slag or gravel. This allows the equipment to enter deeper into the mine tunnel to monitor the roof, thereby accurately monitoring roof data at different locations within the mine. This avoids safety hazards for subsequent mine construction and also prevents on-site personnel from entering the mine tunnel to clean up slag or gravel, and avoids the need for personnel to use the equipment to monitor the roof of the mine tunnel from falling slag or gravel.

[0022] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0023] like Figure 1-8As shown, the embodiment of the present invention includes a base plate 6 and a walking track 1. Both sides of the base plate 6 are equipped with self-rotating tracks 1, each track 1 is equipped with two stepping wheels, and two drive devices (motors) are fixedly installed on one side of each track 1. The power output end of each drive device is fixedly connected to one end of multiple stepping wheels, thereby providing power for the rotation of the track 1 (this is prior art and will not be described in detail here).

[0024] A detector 11 for detecting the roof of the iron ore mine is detachably installed on the top of the base plate 6. The bottom of the detector 11 and the top of the support frame 9 are detachably connected. The detector 11 is a roof delamination meter (model LBY-2, which can be purchased directly on the market). Its core principle is to monitor the relative displacement between base points set at different depths and between shallow base points and the roadway surface. When the roof rock strata deform, move or delaminate, the deep base points and shallow base points will move relative to each other. This relative movement is transmitted to the indicator on the roadway surface through a measuring rope or measuring rod. The device inside the indicator amplifies the small displacement and converts it into a readable scale value or digital signal, thereby intuitively reflecting the delamination situation of the roof rock strata at different depths (this is existing technology and will not be elaborated on here).

[0025] A camera 10 is fixedly installed on the top of the support frame 9 to provide a field of view for the movement direction of the track 1. The camera end of the camera 10 can be continuously pointed to the movement direction of the track 1, thereby providing a field of view for the movement direction of the track 1. At the same time, the camera 10 also has its own lighting to supplement the lighting of the camera end, so that the track 1 can move continuously in the dark mine tunnel and can avoid the slag or gravel in the mine tunnel in time.

[0026] Based on the applicant's understanding of the prior art, in iron ore mines, the terrain is complex and varied, and there may be obstacles such as narrow tunnels, muddy ground, and piles of rubble. If the distance between the two tracks 1 is greater than the width of the mine tunnel, the tracks 1 will be unable to move within the mine tunnel, thus making it impossible to use the detector 11 to detect the roof in the depths of the narrower mine tunnel.

[0027] To solve the aforementioned technical problems, two drive gears 23 are rotatably mounted inside the base plate 6. Each drive gear 23 has a rack plate 16 slidably mounted on its top and bottom, engaging with itself. The ends of the rack plates 16 extending outside the base plate 6 are slidably connected to the drive mechanism of the track 1. The base plate 6 has a chamber for the movement of the rack plates 16 and the rotation of the drive gears 23. Two connecting slots are provided on both sides of the base plate 6, communicating with the chambers. One end of each rack plate 16 passes through the connecting slot and extends outside the chamber. This design allows the detector 11 to operate in confined spaces, such as in a mine tunnel. When moving inside, firstly, rotate the two drive gears 23 simultaneously, causing the four rack plates 16 to extend to one end outside the chamber and move towards the bottom plate 6 until the distance between the two tracks 1 is less than the width of the mine tunnel. Then, start the drive equipment to rotate the two tracks 1, allowing the detector 11 to move continuously in the relatively narrow mine tunnel. This allows the detector 11 to perform roof detection in the depths of the narrow mine tunnel. At the same time, when encountering soft or uneven ground, the grounding pressure can be optimized by adjusting the distance between the two tracks 1, so that the equipment can better adapt to different ground conditions and prevent getting stuck or slipping.

[0028] When the width of the mine shaft is much greater than the distance between the two tracks 1, the two drive gears 23 are rotated in the opposite direction, causing the two tracks 1 to move away from the bottom plate 6 until the distance between the two tracks 1 reaches its maximum value, at which point the drive gears 23 stop rotating. This increases the distance between the two tracks 1, which can effectively increase the lateral support distance of the equipment, lower the center of gravity, and thus improve the anti-overturning ability of the equipment when traveling on complex terrains such as slopes and uneven ground (for example, when the equipment is operating in the inclined roof area of ​​the mining area, the wider track spacing 1 can make the equipment more capable of resisting the lateral component of gravity, reducing the risk of overturning).

[0029] A drive rod 15 is rotatably mounted inside the base plate 6. Both ends of the drive rod 15 are fixedly connected to the adjacent ends of two drive gears 23, respectively. A drive motor is fixedly mounted on the top of the base plate 6. Drive wheels are fixedly sleeved on both the power output end of the drive motor and the outside of the drive rod 15. The two drive wheels are rotatably connected by a tension belt. When it is necessary to make the two drive gears 23 rotate simultaneously, the drive motor is started, and the two drive wheels will rotate simultaneously under the action of the tension belt. By changing the direction of the current passing through the drive motor, the power output end of the drive motor can be rotated in the opposite direction, thereby changing the rotation direction of the two drive gears 23.

[0030] The drive motor is a self-locking motor (model NFP-5840-31ZY-L, which can be purchased directly on the market). Its working principle is based on the meshing characteristics of worm and gear. The worm has a small helix angle. When the worm drives the gear to rotate, the reaction force of the gear on the worm is less than the friction force of the worm, so that the gear cannot drive the worm to rotate in the opposite direction, thus achieving self-locking. This self-locking method has a simple structure, reliable self-locking, and can withstand a large load. It can prevent the tension wheel from rotating again when the drive motor stops, and finally achieve the locking effect on the two drive gears 23, so that the distance between the two tracks 1 remains unchanged.

[0031] Guide plates 21 are fixedly installed on the outer walls of multiple rack plates 16, and guide rails 22 are fixedly installed on the inner walls of the chamber to limit the sliding trajectory of the guide plates 21. Under the action of the guide plates 21 and the guide rails 22, the movement trajectory of the rack plates 16 can be limited, preventing the rack plates 16 from wobbling left and right or up and down when moving or stationary, thus improving the stability of the rack plates 16 when moving or stationary.

[0032] The rack plate 16, drive gear 23, drive rod 15 and guide plate 21 constitute the adjustment component. The adjustment component can make the front of one or both tracks 1 have gravel higher than its own height, which can change the distance between the two tracks 1, so that the two tracks 1 can avoid the gravel and continue to move. There is no need for on-site personnel to enter the mine tunnel to clear the gravel, and the use of the equipment to monitor the roof of the mine tunnel is avoided. This prevents the personnel from being injured by falling gravel or slag.

[0033] Each of the multiple rack plates 16 extending to the outside of the base plate 6 has a fixed block 4. Each of the two track 1s has a fixed guide block 20 on the outside of the drive device. Each of the multiple blocks 4 has a guide groove that matches the guide block 20 at the end away from the rack plate 16. Both the guide block 20 and the guide groove are set as a "T-shaped" structure. When the guide block 20 moves up and down along the inner cavity of the guide groove, it can also prevent the guide block 20 from detaching from the inside of the guide groove.

[0034] A support frame 9 is fixedly installed on the top of the base plate 6. Directional guide rails 2 are symmetrically slidably installed on both sides of the bottom of the support frame 9. The size of the support frame 9 is larger than that of the base plate 6. Four T-shaped grooves are symmetrically opened on both sides of the bottom of the support frame 9. T-shaped sliders are fixedly installed on the top of the four directional guide rails 2. The directional guide rails 2 can slide along the bottom of the support frame 9 with the cooperation of the T-shaped sliders and T-shaped grooves, and prevent the directional guide rails 2 from detaching from the bottom of the support frame 9.

[0035] Based on the applicant's understanding of the prior art, there is a lot of slag and gravel scattered inside the mine tunnel. When the track 1 moves on the gravel or slag, it will inevitably produce a lot of bumps, which will cause the track 1 to bounce. Also, when the track 1 moves at a high speed, it is easy to tilt to one side.

[0036] Sliding blocks 18 are symmetrically slidably installed in the inner cavities of the two directional guide rails 2. Each end of the sliding blocks 18 extending outside the directional guide rail 2 is rotatably mounted with a hinge rod 3 via a rotating shaft. The ends of the hinge rods 3 away from the sliding blocks 18 are rotatably connected to the outer walls of the drive equipment of the two tracks 1. Orienting rods 19 are fixedly installed in the inner cavities of the two directional guide rails 2. Through holes adapted to the orientation rods 19 are opened on the outer walls of the sliding blocks 18. Two return springs 17 adapted to the sliding blocks 18 are symmetrically fixedly sleeved on the outer walls of the orientation rods 19. When the tracks 1 are in the slag... When traveling on gravel surfaces, the vibration generated by the track 1 is transmitted to the articulated rod 3. At this time, both ends of the articulated rod 3 rotate simultaneously, thereby pushing the sliding block 18 located in the directional guide rail 2 to move repeatedly. When the sliding block 18 moves repeatedly in the inner cavity of the directional guide rail 2, the sliding block 18 will repeatedly squeeze the return spring 17, thereby causing the return spring 17 to absorb the vibration generated by the track 1, which can achieve the effect of vibration reduction of the track 1, filter road vibration, reduce the tilting and bouncing of the track 1, and improve the anti-overturning ability of the equipment on slopes and rugged roads.

[0037] The two ends of the directional rod 19 pass through the through hole and are connected to the inner wall of the directional guide rail 2, respectively. Under the action of the directional rod 19 and the through hole, the movement trajectory of the sliding block 18 is limited, preventing the sliding block 18 from shaking when moving along the directional guide rail 2, thus improving the stability of the movement of the sliding block 18.

[0038] Based on the applicant's understanding of the existing technology, if the equipment encounters gravel or slag several times larger than itself while traveling in a relatively wide mine tunnel, or if it is unable to pass through the gravel or slag by changing its path, the equipment will be unable to enter the depths of the mine tunnel to inspect the roof, thus failing to obtain roof data at different locations within the mine, posing a safety hazard to subsequent mine construction.

[0039] To solve the aforementioned technical problems, two rotating shafts 12 are symmetrically installed on both sides of the inner cavity of the support frame 9. Support plates 14 are fixedly installed on the outer walls of each of the rotating shafts 12. A wing 7 is rotatably mounted on the top of the end of each support plate 14 away from the rotating shafts 12, and a brushless motor for rotating the wing 7 is fixedly mounted on the bottom of the end of each support plate 14 away from the rotating shafts 12. Symmetrical storage slots for rotating the support plates 14 are provided on both sides of the support frame 9. If the device encounters gravel or slag several times larger than itself during its forward movement, or if it cannot pass through the gravel or slag by changing its path, the multiple rotating shafts 12 are rotated simultaneously, causing the ends of the support plates 14 away from the rotating shafts 12 to completely pass through the storage slots and move out of the support frame 9, until the multiple support plates 14 are completely removed from the support frame. After the side walls are perpendicular to each other, the four rotating shafts 12 are locked. Then, the four brushless motors are simultaneously energized, causing multiple wings 7 to rotate at high speed. The four high-speed rotating wings 7 simultaneously provide lift to the support frame 9, causing the track 1 to lift off the ground. Once the track 1 is higher than the height of the slag or gravel, the rotation speed of the wings 7 can be controlled to change the angle of the support frame 9, thereby providing forward power to the support frame 9 until the equipment completely passes over the slag or gravel higher than itself. Then, the rotation speed of the four wings 7 and the angle of the support frame 9 are adjusted again to allow the support frame 9 to fall smoothly onto the surface of the slag or gravel. This allows the equipment to enter the depths of the mine tunnel to monitor the roof, thereby accurately monitoring the roof data at different locations in the mine and avoiding safety hazards for subsequent mine construction.

[0040] Each of the multiple support plates 14 is fixedly equipped with a protective cover 13 for protecting the wing 7. The protective cover 13 can protect the wing 7 and prevent small gravel or slag from flying in the air and colliding with the wing 7 due to the airflow generated when the wing 7 rotates at high speed.

[0041] Multiple rotating shafts 12 have transmission gears 24 fixedly sleeved on their outer walls. Two U-shaped plates 25 are symmetrically slidably installed in the inner cavity of the support frame 9. Multiple locking teeth that engage with the transmission gears 24 are fixedly installed on both sides of the two U-shaped plates 25. Threaded holes are opened on the top of the two U-shaped plates 25. A bidirectional threaded rod 8 for synchronous sliding of the two U-shaped plates 25 is rotatably installed between the two threaded holes. A transmission motor is fixedly installed on the top of the support frame 9. Transmission wheels are fixedly sleeved on the power output end of the transmission motor and one end of the bidirectional threaded rod 8. The two transmission wheels are rotatably connected by a transmission belt. When the four support plates 14 are perpendicular to the outer wall of the support frame 9, the transmission motor is started, causing the bidirectional threaded rod 8 to rotate. At this time, the two U-shaped plates 25 move closer to each other, so that the two transmission gears 24 on the diagonal can rotate in the same direction under the action of the multiple locking teeth. Finally, the four support plates 14 rotate simultaneously away from the interior of the support frame 9 until the four support plates 14 are completely perpendicular to the outer wall of the support frame 9.

[0042] When the equipment passes through large-sized gravel or slag and touches the ground again on the track 1, in order to prevent the support plates 14 from colliding with the gravel or slag and being damaged or causing the equipment to stop moving, the direction of the current passing through the internal current of the drive motor is changed, so that the power output end of the drive motor rotates in the opposite direction until the end of the four support plates 14 away from the rotating shaft 12 completely passes through the storage groove and enters the inner cavity of the support frame 9. This prevents the equipment from colliding with gravel, slag or the inner wall of the mine tunnel during its movement in the mine tunnel, which could cause it to stop or the support plates 14 to be damaged.

[0043] Guide holes are provided at the top of both U-shaped plates 25, and limiting rods 5 for limiting their own movement trajectory are fixedly installed at the top of both U-shaped plates 25. The two ends of the limiting rods 5 pass through the guide holes and are fixedly connected to the outer wall of the support frame 9. With the cooperation of the guide holes and the limiting rods 5, the movement trajectory of the U-shaped plates 25 can be limited, preventing the two U-shaped plates 25 from swaying left and right or up and down during movement, thus improving the stability of the two U-shaped plates 25 when moving.

[0044] The wing 7, rotating shaft 12, support plate 14, and transmission gear 24 constitute the crossing component. The crossing component provides lift to the equipment, enabling it to continue moving forward in a relatively wide mine tunnel when encountering slag or gravel larger than itself, until it crosses the larger gravel or slag. This allows the equipment to enter the depths of the mine tunnel to monitor the roof, thereby accurately monitoring the roof data at different locations within the mine. This avoids safety hazards for subsequent mine construction and also prevents on-site personnel from entering the mine tunnel to clean up gravel or slag, and avoids the need for personnel to use the equipment to monitor the roof of the mine tunnel from falling gravel or slag.
