[0002] Coal mines refer to underground or surface mines that mine coal resources. Coal mines usually refer to geological areas with rich coal reserves, where coal resources are mined from underground or on the surface through mining equipment and technology. During the coal mining process, the role of geological disaster early warning equipment in coal mines is to monitor factors such as geological activities, geological structural changes and groundwater levels in order to detect geological anomalies that may lead to disasters in advance. These devices can help miners and managers obtain early warning information in a timely manner, take corresponding safety measures, reduce the possibility of accidents, and protect the lives of miners and the integrity of mine facilities.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figures 1 to 5 As shown:

[0021] Embodiment 1: The utility model provides a coal mine geological disaster early warning device, comprising: an early warning mechanism 1, comprising a support frame assembly 11, a force rod assembly 12 slidably embedded in the support frame assembly 11, and a spring 13 sleeved on the force rod assembly 12; a set of lifting mechanisms 2, including a lifting assembly 21, and a mounting shaft frame assembly 22 fixedly mounted on the lifting assembly 21; both ends of the support frame assembly 11 are respectively rotatably embedded in the corresponding mounting shaft frame assembly 22;

[0022] During installation, the lifting assembly 21 can be used to drive the force-bearing rod assembly 12 close to the top of the tunnel. By installing the axle frame assembly 22, the support frame assembly 11 can be easily rotated to fit the inclined tunnel. When the top of the coal mine is deformed, the force-bearing rod assembly 12 will be pushed downward and move downward along the support frame assembly 11. The deformation of the tunnel top can be judged by observing the bottom of the force-bearing rod assembly 12 extending out of the support frame assembly 11, thereby reminding the staff to reinforce the tunnel.

[0023] Specifically, the support frame assembly 11 includes a support frame body 111, both ends of the support frame body 111 are fixedly connected with a rotating shaft 112, a ring frame 113 is arranged in the middle of the support frame body 111, the lower end of the ring frame 113 is fixedly connected with a U-shaped marking frame 114, and a group of ring frame 2 115 is also fixedly connected to the support frame body 111.

[0024] Specifically, the force-bearing rod assembly 12 includes a cross bracket 121, a guide rod 122 is fixedly connected to the middle position of the lower side of the cross bracket 121, an arrow 123 is also fixedly connected to the bottom of the guide rod 122, and guide rods 124 are fixedly connected to both ends of the lower side of the cross bracket 121.

[0025] Specifically, the guide rod 122 is slidably embedded in the annular frame 113, the arrow 123 is slidably embedded in the U-shaped marking frame 114, and the guide rod 2 124 is slidably embedded in the annular frame 115.

[0026] As can be seen from the above, the cross bracket 121 is supported on the annular frame 113 by the spring 13. When the cross bracket 121 is pressed downward, the guide rod 122 will slide in the annular frame 113. At the same time, when the arrow 123 slides to the specified position on the U-shaped marking frame 114, the staff can judge the deformation of the tunnel according to the position of the arrow 123. At the same time, the guide rod 124 slides along the annular frame 115 to play a guiding role, ensuring that the cross bracket 121 can be lowered as a whole when any point is pressed downward.

[0027] Embodiment 2: This embodiment is basically the same as the previous embodiment, except that the lifting assembly 21 includes a group of electric telescopic rods 211, and the upper ends of the group of electric telescopic rods 211 are fixedly connected to the connecting rods 212; the mounting shaft frame assembly 22 includes a mounting plate 221, the upper end of the mounting plate 221 is fixedly connected to the supporting shaft frame 222, and the bottom of the mounting plate 221 is fixedly connected to the threaded rod 223.

[0028] Specifically, the mounting plate 221 is embedded in the connecting rod 212 and fixed by the threaded rod 223 , and the rotating shaft rod 112 is rotatably embedded in the supporting shaft frame 222 .

[0029] As can be seen from the above, the mounting plate 221 is embedded in the connecting rod 212 and fixed by the threaded rod 223, and the rotating shaft rod 112 is rotatably embedded in the supporting shaft frame 222 so that the cross bracket 121 can be attached to the top of the tunnel, and the connecting rod 212 can be driven up and down by the electric telescopic rod 211, thereby facilitating the cross bracket 121 to move to a position close to the top of the tunnel.
