This patent is to provide an open-pit coal mine slope stability monitoring device to alleviate the technical problem that the existing monitoring device in the prior art requires the staff to detect all the monitoring points near the slope one by one, and the workload of the staff is heavy.

[0004] During the use of the above device, when the displacement of the coal mine slope is measured and the angle deviation is monitored, the base may be offset when fixed, which may cause the alarm to detect errors. Therefore, an open-pit coal mine slope stability monitoring device is proposed. Summary of the invention

[0005] The purpose of the present invention is to solve the problem in the prior art that when the displacement of the coal mine slope is measured and the angle deviation is monitored, the base may be offset when it is fixed, resulting in measurement errors and possible false alarms of the alarm, thereby proposing an open-pit coal mine slope stability monitoring device.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A slope stability monitoring device for an open-pit coal mine comprises a box body, a distance measuring device is arranged inside the box body, a second rotating block is arranged on one side of the distance measuring device, the second rotating block is rotatably connected to a third connecting rod frame, the third connecting rod frame is rotatably connected to a second connecting rod, the second connecting rod side is rotatably connected to a first connecting rod, the first connecting rod is fixed below a connecting plate, a second convex block is fixedly connected below the connecting plate, and the second convex block is rotatably connected to a connecting block;

[0008] The connecting block is rotatably connected with the first convex block, a stabilizing column is arranged below the first convex block, a first supporting rod is fixedly connected below the connecting plate, the first supporting rod is rotatably connected with the second supporting rod, the second supporting rod is rotatably connected with the third supporting rod, a first rotating block is arranged on one side of the third supporting rod, a monitoring mechanism is arranged above the connecting plate, the monitoring mechanism is used to monitor the angular deviation of the slope, an output rotating block is fixedly connected above the connecting plate, the output rotating block is fixedly connected with a worm, the worm is meshed with a worm wheel, the worm wheel is fixedly connected with the supporting thick block, and the probability of false alarms is reduced by adjusting the horizontality and detecting whether the device is horizontal. The alarm will only be issued when there is indeed an unstable slope, avoiding unnecessary waste of resources and psychological pressure caused by false alarms.

[0009] The above technical solution further includes:

[0010] The monitoring mechanism includes a block arranged above the supporting thick block, a second rotating bar is fixedly connected above the block, the second rotating bar is rotatably connected to the first rotating bar, a rotating engagement box is arranged above the first rotating bar, a fan-shaped bevel gear is arranged at the bottom of the rotating engagement box, the fan-shaped bevel gear is fixed to the side of the second rotating bar, a supporting wide plate is arranged above the connecting plate, a protractor piece is fixedly connected to the side of the supporting wide plate, the protractor piece is slidably connected to a slope contact strip, and the supporting wide plate is rotatably connected to the slope contact strip.

A rotator is arranged inside the rotating meshing box, a slide groove is arranged on the side of the supporting wide plate, and a scale is arranged on one side of the angle measuring piece. If a large angle deviation occurs, the control room can issue a corresponding alarm according to the multi-level alarm range of the scale above the angle measuring piece. For a smaller alarm range, the staff can check it in person, ensuring the pertinence and timeliness of the early warning.

[0016] The present invention has the following beneficial effects:

[0017] 1. In the present invention, the device ensures the stability of the monitoring device during use by driving the base fixture into the ground fixing box. During the monitoring process, the distance measuring device emits rays to detect whether the device is horizontal, and the authenticity of the camera shooting value is verified, thereby avoiding erroneous data caused by the angle deviation of the device itself, and providing a reliable basis for accurately judging the stability of the slope.

[0018] 2. The slope contact strip fits the slope. This graded warning mechanism improves the reliability of the warning, allowing staff to take appropriate countermeasures according to different situations.

[0041] The working principle of an open-pit coal mine slope stability monitoring device in the present invention is to first check whether the device between the internal device gears is normal, then fix the box body 1 by driving the base fixer 11 into the ground, then arrange the lines, check whether the first rotating block 9 and the second rotating block 10 are operating normally, and then fit the slope contact strip 26 to the slope through the height adjustment spiral card on one side of the supporting wide plate 25.

[0042] If the length is not enough, a bayonet is provided at the end, so that a longer strip can be connected for fixing. Then the second rotating block 10 and the first rotating block 9 are started, and the distance measuring devices 12 on the four sides above the box body 1 will emit light and then reach the bottom of the connecting plate 2. Then the distance measuring device 12 will upload four sets of data to the control room, and then the control room controls the rotation of the second rotating block 10 and the third connecting rod frame 5, and then drives the distance between the second connecting rod 4 and the first connecting rod 3, and controls the rotation of the first rotating block 9 to adjust the third support rod 8 and the second support rod 7, and then drives the second support rod 7 and the first support rod 6 to be fine-tuned. Rotate. If the light distance on the side close to the first rotating block 9 is far, it can be adjusted by rotating the first rotating block 9. Before the second rotating block 10 and the first rotating block 9 are started, the silent box 1 is fixed on the ground and is horizontal. At this time, by placing the slope contact strip 26 at the slope just at the initial angle, after starting the second rotating block 10 and the first rotating block 9, start to adjust the horizontality of the connecting plate 2 to the initial angle. If the slope contact strip 26 has a large angle deviation, the control room can sound an alarm. There are multiple levels of alarm ranges on the scale above the protractor 27. The smaller alarm range only requires the staff to check it in person.

[0043] By setting the number of monitoring times within a period of time, the rotating engagement box 28 on the side of the first rotating bar 19 can be controlled to rotate, and then the camera is deflected by the engagement of the fan-shaped bevel gear 21 and the rotating bevel gear 22. During one monitoring, the output rotating block 30 can be controlled to drive the worm 23 and the worm wheel 24 to engage and deflect the supporting thick block 17 to achieve shooting at different angles. After shooting, the distance measuring device 12 emits rays to detect whether it is horizontal. In this way, the authenticity of the value of the side of the protractor piece 27 shot by the camera can be greatly increased, avoiding the situation where the device itself has an angle offset and thus an error is reported.
