Roof accidents are the most common accidents in coal mines, especially local roof collapse accidents, which are extremely harmful to coal mining. Therefore, mastering the roof displacement is the key monitoring object in coal mining.

[0003] Currently, in the process of coal mining, the displacement of the roof rock layer is often monitored by a roof separation meter. However, because it is relatively dark inside the mine, when observing the separation meter, the staff needs to hold a handheld electric light to illuminate the reflective sticker of the separation meter to know the separation situation of the roof rock layer. Moreover, when observing the separation meter, only the current reading can be seen. When the separation instrument suddenly moves a lot, it is impossible to alert the personnel in time, which is quite dangerous. Therefore, it is of great significance to study a new roof rock displacement monitoring device based on elastic deformation to solve the above problems. Utility Model Content

[0024] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0025] like Figure 1-5As shown, the utility model provides a technical solution: a roof rock displacement monitoring device based on elastic deformation, including a roof delamination meter 1, through which the displacement of the rock layer can be detected, and the roof delamination meter 1 is an existing mature technology, and detects the rock layer by elastic deformation, so the specific working process does not need to be redundantly described here, both ends of the roof delamination meter 1 are provided with a scale ring 2, and an alarm 5 is fixedly installed at the bottom of the scale ring 2, and an audible and visual alarm can be performed by the alarm 5, which is convenient for construction personnel to detect in time, and a transmission component 6 is provided on the scale ring 2, and the transmission component 6 is driven by a pinion 11, and the pinion 11 is fixedly connected to the drum 12, and one end of the drum 12 is connected to the centrifugal air pressure control component 7, and the centrifugal air pressure control component 7 is connected to the centrifugal air pressure control component 7. The pressure control assembly 7 includes a centrifugal shell 71, which is connected to the drum 12. The centrifugal shell 71 is connected to a plurality of arc tubes 73. A first piston 72 is provided in the arc tube 73. One end of the first piston 72 is fixedly connected to a weighted ball 74. When the centrifugal shell 71 performs centrifugal motion, the weighted ball 74 cooperates with the centrifugal motion of the centrifugal shell 71 to smoothly drive the first piston 72 to move, thereby controlling the movement of the second piston 83 through negative pressure. A moving assembly 8 is provided inside the drum 12. The moving assembly 8 includes a second piston 83. The second piston 83 is provided in the drum 12. A spring 84 is fixedly connected between the second piston 83 and the end wall of the drum 12. The second spring 84 can maintain the position of the second piston 83, thereby enabling the first piston 72 to move. The position of the second piston 83 can be stabilized, and a connecting rod 82 is fixedly connected to one side of the second piston 83. The connecting rod 82 passes through the rotating cylinder 12 and is fixedly connected to the roller 81. The rolling of the roller 81 can reduce the resistance between it and the scale 3 and maintain smooth movement. A switch 9 is also installed inside the rotating cylinder 12. A scale 3 is provided at one end of the moving component 8. One end of the scale 3 is widened, and the wide surface and the narrow surface of the scale 3 are inclined. When the roller 81 moves to the inclined surface of the scale 3, the inclined surface squeezes the roller 81 to drive the connecting rod 82 and the second piston 83 to move. The second piston 83 touches the switch 9 to realize the alarm 5 to alarm, thereby realizing the operation of automatic sound and light alarm when the scale ring 2 moves to the danger line, without the need for construction personnel to observe. The scale 3 is fixedly connected to Below the roof delamination instrument 1, a gear rod 4 is also fixedly connected to the bottom of the roof delamination instrument 1, and the gear rod 4 is transmitted to the transmission assembly 6. The transmission assembly 6 includes a rotating rod 62, and the rotating rod 62 is rotatably mounted on the scale movable ring 2 through a bearing. The rotating rod 62 can rotate stably through the bearing, so that the first gear 63 and the large gear 61 can rotate stably. The first gear 63 and the large gear 61 are fixedly connected to the rotating rod 62. The first gear 63 is meshed with the gear rod 4, and the large gear 61 is meshed with the small gear 11. Through the transmission of the large gear 61 and the small gear 11, not only power transmission can be achieved, but also the transmission efficiency is improved, so that the small gear 11 accelerates the rotation speed of the rotating drum 12. The rotating drum 12 is rotatably mounted on the mounting seat 10 through the bearing. The rotating drum 12 can maintain smooth rotation through the bearing.The mounting seat 10 is fixedly connected to the scale ring 2.

[0026] The working principle of the utility model is as follows: the top rock layer of the tunnel can be detected by the roof rock layer instrument. When the rock layer is displaced, the roof rock layer instrument can drive the scale ring 2 to move, and the scale ring 2 drives the rotating drum 12 to move, so that the roller 81 moves along the scale 3. When the roller 81 and the inclined surface of the scale 3 move, the roller 81 pushes the connecting rod 82 and the second piston 83 to move, so that the second piston 83 presses the switch 9, and the switch 9 controls the alarm 5 to sound an alarm. At this time, it can be timely known that the scale ring 2 has moved to the danger line.

[0027] When the movement of the scale ring 2 is accelerated, the first gear 63 and the gear rod 4 are transmitted quickly, and the first gear 63 drives the rotating rod 62 to rotate, so that the transmission efficiency between the large gear 61 and the small gear 11 is improved, and the small gear 11 drives the rotating drum 12 and the centrifugal shell 71 to move quickly, so that the centrifugal force controls the displacement of the first piston 72, and the second piston 83 is driven to move by the negative pressure, so that the second piston 83 presses the switch 9 to control the alarm 5 to alarm.
