Description

Technical Field

[0001] This utility model relates to the technical field of coal mine monitoring equipment, and in particular to a safety monitoring device for cracks in coal mine goaf areas. Background Technology

[0002] A coal mine goaf refers to an underground cavity area formed after coal mining. With the continuous extraction of coal resources, the underground rock strata lose support, leading to surface subsidence, cracks, and even collapses, potentially triggering geological disasters such as ground subsidence and landslides. Goafs not only threaten the safe production of coal mines but can also affect surrounding buildings, roads, farmland, and the ecological environment. To reduce the hazards of goafs, measures such as backfilling mining, leaving coal pillars, and surface monitoring are commonly adopted.

[0003] Existing crack safety monitoring equipment is easily affected by ground factors during operation. It is prone to displacement and shaking due to uneven ground, and in some soils with loose soil, the equipment is more likely to collapse during monitoring, affecting the accuracy of subsequent monitoring data and reducing its practicality. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the previous invention by proposing a safety monitoring device for cracks in coal mine goaf areas.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A safety monitoring device for cracks in coal mine goaf areas includes two support sleeves. Two fixing plates are installed on the lower surface of each of the two support sleeves. A receiving plate is fixedly connected to the lower surface of the fixing plate. A drive motor is set at the middle position of the upper surface of the receiving plate. A drive rod is set at the power output end of the drive motor. A drill rod is fixedly connected to the lower surface of the drive rod.

[0007] A connecting block is fixedly connected to the middle position of the lower surface of the receiving plate. A movable frame is movably connected to the outer surface of the connecting block via a pin. A connecting plate is fixedly connected to the lower surface of the movable frame. A rotating shaft is provided on the lower surface of the connecting plate. A telescopic rod is provided on the lower surface of the rotating shaft. There are four telescopic rods. A support ring is fixedly connected to the lower surface of the four telescopic rods.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1

[0023] Reference Figure 1-4 A safety monitoring device for cracks in coal mine goaf includes two support sleeves 1. Two fixing plates 2 are installed on the lower surface of each of the two support sleeves 1. A receiving plate 3 is fixedly connected to the lower surface of the fixing plate 2. A drive motor 4 is set at the middle position of the upper surface of the receiving plate 3. A drive rod 5 is set at the power output end of the drive motor 4. A drill rod 6 is fixedly connected to the lower surface of the drive rod 5.

[0024] A connecting block 7 is fixedly connected to the middle position of the lower surface of the receiving plate 3. A movable frame 8 is movably connected to the outer surface of the connecting block 7 via a pin 28. A connecting plate 9 is fixedly connected to the lower surface of the movable frame 8. A rotating shaft 10 is provided on the lower surface of the connecting plate 9. The connecting block 7 and the movable frame 8 are movably connected via the pin 28. The cooperation of the connecting block 7, the movable frame 8, the pin 28, and the rotating shaft 10 can produce a bending effect, which allows the device to monitor cracks with different slopes.

[0025] The lower surface of the rotating shaft 10 is provided with four telescopic rods 11. The lower surfaces of the four telescopic rods 11 are fixedly connected with support rings 12. The telescopic rods 11 and support rings 12 can play an auxiliary support role. When the drill rod 6 moves downward, the telescopic rods 11 will also extend and retract to suit the drilling depth of the drill rod 6. When the drill rod 6 reaches a suitable position in the soil around the crack, the drill rod 6, the telescopic rods 11 and the support rings 12 work together to fix the equipment.

[0026] A square block 13 is fixedly connected to the middle position of the lower surface of the fixed plate 2. A telescopic plate 14 is fixedly connected to the left side of the right square block 13, and the left side of the telescopic plate 14 is fixedly connected to the right side of the left square block 13. The telescopic plate 14 can extend and retract left and right, and the distance between the two support sleeves 1 can be adjusted to adapt to cracks of different widths.

[0027] A groove 15 is provided in the middle of the upper surface of the support sleeve 1. A sliding block 17 is slidably connected to the inside of the groove 15 through a slider 16. A square rod 18 is fixedly connected to the left side of the right sliding block 17, and the left side of the square rod 18 is fixedly connected to the right side of the left sliding block 17. A circular sleeve 19 is fitted onto the outer surface of the square rod 18. A threaded groove 20 is provided in the middle of the upper surface of the circular sleeve 19. Strip grooves 21 are provided on the front and rear sides of the upper surface of the circular sleeve 19. A lead screw 22 is threadedly connected to the inside of the circular sleeve 19. A rotating handle 23 is fixedly connected to the upper surface of the lead screw 22. The operator can adjust the position of the circular sleeve 19 on the outer surface of the square rod 18 through the strip groove 21, and can further adjust the position of the sliding block 17 and the square rod 18 through the groove 15 and the slider 16, which facilitates further monitoring of the equipment.

[0028] A receiving block 24 is fixedly connected to the lower surface of the lead screw 22, a connecting rope 25 is fixedly connected to the lower surface of the receiving block 24, a placement frame 26 is fixedly connected to the lower surface of the connecting rope 25, and an industrial monitoring camera 27 is installed on the inner bottom wall of the placement frame 26. Since most of the cross-sections in the crack are uneven, the relatively soft connecting rope 25 makes it easier for the industrial monitoring camera 27 to monitor inside the crack.

[0029] Existing crack safety monitoring equipment is easily affected by the ground when it is in operation. It is prone to displacement and shaking due to uneven ground. In some soils, the equipment is more likely to collapse during monitoring, which affects the accuracy of subsequent monitoring data and reduces its practicality.

[0030] When using the device, the operator first extends the telescopic plate 14 to the most suitable monitoring position, then places the entire device above the crack, and positions the placement frame 26 and industrial monitoring camera 27 above the crack to be monitored. The operator then starts the drive motor 4, which in turn rotates the drive rod 5. The rotation of the drive rod 5 then rotates the drill rod 6, causing it to drill into the soil around the crack, thus providing a stable anchor and preventing the monitoring equipment from shaking and affecting its accuracy. The operator then rotates the handle 23, which causes the lead screw 22 to move up and down. This movement of the lead screw 22 moves the placement frame 26 and industrial monitoring camera 27 below it up and down, allowing for monitoring of the depth of the crack in the goaf, increasing its practicality.

[0031] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
