Description

Technical Field

[0001] This invention relates to the field of crack monitoring technology, and in particular to a tool for monitoring and early warning of slope collapse and cracks in open-pit mines. Background Technology

[0002] Open-pit mines, as an important form of mineral resource extraction, are widely used in the development and utilization of large-scale mineral resources such as coal, iron ore, and non-ferrous metal mines due to their advantages such as high mining efficiency, high resource recovery rate, and relatively low mining cost. Open-pit mines strip away the topsoil, weathered rock, and hard rock layer by layer to form a stepped slope structure, and then mine the underground ore body. Their mining scale often reaches millions to tens of millions of tons, making them an indispensable resource supply base for industrial production. During the open-pit mining process, the slope rock mass is easily affected by multiple factors such as geological structure, blasting vibration, groundwater erosion, rainwater scouring, slope self-weight, and mining disturbance, which can cause cracks to form and gradually expand.

[0003] However, during open-pit mining, the gradual expansion of cracks leads to limited stability of the slope rock mass. Although some devices monitor crack size, workers still need to take readings to obtain information about slope stability. This method of operation is not only difficult, but if the crack size is too small, the slope may collapse and injure the workers. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the aforementioned technical problems in the prior art by proposing a monitoring and early warning tool for slope collapse and cracks in open-pit mines.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A tool for monitoring and early warning of slope collapse and cracks in open-pit mines includes a mounting box and a frame. A bidirectional threaded rod is rotatably connected inside the mounting box. The bidirectional threaded rod is threadedly connected to a first movable plate and a second movable plate. A connecting rod is fixedly connected to one side of the first movable plate. A first contact block is fixedly connected to the end of the connecting rod away from the first movable plate. A cylindrical rod is fixedly connected to one side of the second movable plate. A compression spring is fixedly connected inside the cylindrical rod. A penetration rod is fixedly connected to the end of the compression spring away from the cylindrical rod. The penetration rod is slidably connected to the cylindrical rod. An installation rod is fixedly connected to the end of the penetration rod away from the compression spring. One end of the penetration rod is fixedly connected to a second contact block. The mounting rod is meshed with a first gear, which is driven by a second gear. The second gear is meshed with a rack. A short contact plate is provided on the side of the rack near the first contact block. The mounting box contains a first contact block and a second contact block. A warning block is provided on the side of the second contact block. An indicator light is linearly connected to the first and second contact blocks. A processing mechanism is provided on the side of the indicator light to ensure that it emits light normally. A worm gear is fixedly connected to the bidirectional threaded rod. The worm gear is meshed with a worm. A connecting rod is installed above the worm.

[0006] The above technical solution further includes: The first movable plate is slidably connected to the mounting box, the connecting rod is slidably connected to the mounting box, the mounting box is slidably connected to the second movable plate, the mounting rod is slidably connected to the mounting box, the inside of the cylindrical rod is provided with a circular groove for sliding of the insertion rod, the first gear is rotatably connected to the mounting box, the first gear is driven by a first belt, the end of the first belt away from the first gear is driven by a second gear, the second gear is rotatably connected to the mounting box, the initial position of the contact plate on the side of the rack is located at the part that can only contact the first contact block, and the inside of the mounting box is provided with an electric pull rope for pulling the second contact block.

[0007] The processing mechanism includes an electric meshing disc mounted above the frame. The electric meshing disc is meshed with a geared disc, which is rotatably connected to the frame. A support column is fixedly connected above the geared disc, and a first bevel gear is fixedly connected above the support column. The first bevel gear meshes with a second bevel gear. A rotating disc is fixedly connected to the side of the second bevel gear, which passes through a side plate. The side plate is fixed above the frame. The rotating disc is eccentrically rotatably connected to a first connecting strip. A second connecting strip is rotatably connected to the end of the first connecting strip away from the rotating disc. A fastener is slidably connected to the second connecting strip, which is fixed to one side of the side plate. A sliding ring is fixedly connected to the side of the second connecting strip. A cleaning surface layer for cleaning the surface of the indicator lights is provided inside the sliding ring. The geared disc is driven through the frame and connected to a second belt. A solar panel column is driven through the end of the second belt away from the geared disc, and the solar panel column is rotatably connected to the frame.

[0008] A thin rope is fixedly connected to the bottom of the frame, the mounting box is fixedly connected to the cover plate, a fixing cylinder is fixedly connected to the top of the cover plate, the inside of the fixing cylinder is provided with a long groove for installing the thin rope, and a threaded torsion bar is threadedly connected to the side of the fixing cylinder.

[0009] The thin rope below the frame works in conjunction with the fixing cylinder of the mounting box and is locked in place by a threaded torsion bar. This allows for a flexible connection and positional calibration between the mounting box and the frame, preventing relative displacement caused by explosive vibrations. At the same time, the long groove design facilitates the installation and adjustment of the thin rope, improving the overall installation stability and adaptability of the device.

[0010] The mounting box is fixedly connected to a fixing block, which is rotatably connected to a connecting rod. A rotating block that penetrates the surface of the cover plate is provided above the connecting rod.

[0012] Both ends of the frame are provided with insertion rods for fixing.

[0013] The insertion rods at both ends of the frame can be quickly inserted into the rock mass in the safe area near the crack, so as to quickly fix the frame. The fixing method is firm and can withstand the effects of blasting vibration and wind, ensuring that warning components such as indicator lights are always in a stable state and ensuring that the warning effect is uninterrupted.

[0014] A long column is provided below the indicator light, and the long column is fixed above the frame.

[0015] The cover plate has a circuit on its surface for linearly connecting the first and second contact blocks to the indicator light.

[0016] The bottom of the worm gear is rotatably connected to a mounting box.

[0017] The bottom of the worm gear is rotatably connected to the mounting box, providing a stable support point for the worm gear. This ensures precise meshing between the worm gear and the worm wheel, preventing misalignment due to vibration, ensuring smooth power transmission, and thus ensuring the accuracy of crack width monitoring and early warning signal triggering.

[0018] The present invention has the following beneficial effects: 1. In this invention, there is no need for manual close-range reading of crack data. The automated monitoring and graded early warning mechanism directly outputs intuitive warning signals, completely avoiding the need for workers to stay and work in dangerous areas, effectively avoiding personnel injuries caused by sudden slope collapses, and greatly improving the safety and reliability of the monitoring process.

[0019] 2. In this invention, the information acquisition process is simplified. Staff can quickly grasp the risk level through the early warning signal without complicated readings and analysis, which reduces the difficulty of the work, shortens the response time, and provides efficient support for timely handling of hidden dangers and avoidance of collapse accidents. In addition, the automatic cleaning mechanism of the lamp ensures that the lamp is clean and prevents the surface from being covered with too much dust, which would reduce the warning effect.

[0033] In one embodiment, the cover plate 2 has a circuit on its surface for linear connection between the first contact block 19 and the second contact block 20 and the indicator light 35.

[0034] In one embodiment, for the worm gear 5 described above, the bottom of the worm gear 5 is rotatably connected to the mounting box 1.

[0035] In this embodiment, the bottom of the worm 5 is rotatably connected to the mounting box 1, providing a stable support point for the worm 5, ensuring precise meshing between the worm 5 and the worm wheel 501, avoiding meshing misalignment due to vibration, ensuring smooth power transmission, and thus ensuring the accuracy of crack width monitoring and early warning signal triggering.

[0036] The working principle of the open-pit mine slope collapse and crack monitoring and early warning tool in this invention is as follows: First, the mounting box 1 is installed in the crack. Then, the connecting rod 6 is rotated manually. The rotation of the connecting rod 6 drives the worm gear 5 to rotate. The rotation of the worm gear 5 meshes with the worm wheel 501. The rotation of the worm wheel 501 drives the bidirectional threaded rod 3 to rotate. The rotation of the bidirectional threaded rod 3 causes the second moving plate 9 and the first moving plate 8 to move away from each other. Then, the first moving plate 8 drives the first contact block 4 on the side of the connecting rod 10 to press against one side of the crack. Then, the second moving plate 9 drives the cylinder rod 11, compression spring 12, penetration rod 13, and second contact block 401 to press against the other side of the crack. After pressing, the electric pull rope 22 on the side of the second moving plate 9 is used to release the pull on the second contact block 401. At this time, the compression spring 12 is no longer subjected to compressive force. When the crack grows larger, the compression spring 12 releases elastic potential energy. As the crack grows larger, the compression spring 12 will squeeze the mounting rod 14 on the side of the penetration rod 13, causing the second contact block 401 to press against the crack. At this time, as the crack grows larger, the mounting rod 14 slides. It will mesh with the first gear 15. The rotation of the first gear 15 will drive the second gear 17 to rotate via the first belt 16. Then, the rotation of the second gear 17 will mesh with the rack 18. The rack 18 slides. In the initial position, the contact plate on the side of the rack 18 only touches the first contact block 19, and the contact plate is short, so it can only contact one of the first contact block 19 and the second contact block 20. When the crack widens, it will cause the rack 18 to slide. Then, the rack 18 will change from contacting only the first contact block 19 to contacting only the second contact block 20. Then, in the initial position, when the first contact block 19 contacts the contact plate on the side of the rack 18, the indicator light 35 will emit a green light, indicating that it is safe to pass. When the rack 18 slides and its contact plate contacts the second contact block 20, the indicator light 35 will emit a yellow light, indicating that the crack is widening. Please follow the instructions of the staff to determine whether it is safe to pass. When the rack 18 continues to slide, its contact plate will contact the warning block 21, at which point a red light will be emitted, indicating that it is not allowed to pass. If the crack is too large, it may cause an accident. The above lights may not be the colors described above and may be set to other colors.

[0037] When installing the mounting box 1, the frame 23 is simultaneously installed in a safe area near the crack, and then placed in a conspicuous area. When the sunlight is strong during the day, the electric meshing disc 29 is rotated by controlling it. The electric meshing disc 29 is electrically controlled, and its rotation will mesh with the gear disc 24. The gear disc 24 passes through the frame 23 and drives the solar panel column 36 to rotate via the second belt 40, thus ensuring that it can rotate at the angle of strongest sunlight in the open-pit mine. At the same time, the gear disc 24 drives the first bevel gear 25 above the support column 30 to rotate. The first bevel gear 25 and the second bevel gear 26... The gears engage, and the second bevel gear 26 continues to penetrate the side plate 27, driving the rotating disk 28 to rotate. Then, the electric engagement disk 29 drives one end of the first connecting bar 31 to perform eccentric circular motion. Then, the first connecting bar 31 drives one side of the second connecting bar 32 to rotate. Since the second connecting bar 32 is restrained by the buckle 33, it can only move up and down. Therefore, when the rotating disk 28 rotates, the sliding ring 34 on the side of the buckle 33 will move up and down to clean the surface of the indicator light 35, thus preventing the indicator light 35 from being dim due to rainwater, mud, or dust caused by explosions.

[0038] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
