Description

Technical Field

[0001] This utility model relates to the field of safety warning, specifically to a rockfall safety warning device for mining. Background Technology

[0002] During the mining process in open-pit mines, as mining progresses, the sidewalls formed by the benches being mined and those to be mined form the working sidewalls of the open-pit mine. The position of the working sidewalls is not fixed and changes continuously as mining progresses. The imaginary slope drawn through the top line of the uppermost bench and the bottom line of the lowermost bench of the non-working sidewall is called the non-working sidewall slope or final sidewall slope of the open-pit mine. Explosives are sometimes used in coal mining, and the ground vibration caused by the explosion of explosives can easily cause rocks to roll down the slope at the uppermost bench of the non-working sidewall, which can seriously threaten the lives of the workers working at the bottom of the pit. In order to improve the protection of workers, mines usually install protective plates to prevent falling rocks at the edge of the slope at the bottom of the pit.

[0003] However, existing protective plates only serve as devices to prevent rocks from rolling down, and cannot promptly alert personnel on-site and in the control room after rocks have rolled down. In addition, existing protective plates are usually made of a single piece of material, which has weak buffering capacity. The impact of falling rocks can be directly transmitted to the main structure, and it can also easily cause the baffle to deform, reducing the blocking effect and shortening the service life of the overall device. Therefore, we propose a rockfall safety warning device for mining. Utility Model Content

[0005] To achieve the aforementioned objectives and address the aforementioned problems, this utility model provides a rockfall safety warning device for mining, comprising a mounting base, the mounting base being U-shaped, a baffle slidably connected between two vertical plates of the mounting base, a connecting rod fixedly connected to the rear surface of the baffle, a mounting frame fixedly connected to the end of the connecting rod, a metal chain mesh fixedly connected to the inner wall of the mounting frame, an arc-shaped baffle fixedly connected to the upper surface of the baffle, two mounting sleeves fixedly connected to the front surfaces of the two vertical plates of the mounting base, an elastic metal plate fixedly connected between the two mounting sleeves, connecting ears fixedly connected to both the left and right surfaces of the mounting base, inclined support plates fixedly connected to the front surfaces of both vertical plates of the mounting base, a stabilizing plate fixedly connected to the side of the inclined support plate away from the mounting base, connecting pins provided on the stabilizing plate and the connecting ears, and a warning device provided on the mounting base.

[0006] As a preferred technical solution of this application, the warning device includes a mounting plate, which is fixedly connected between two vertical plates of the mounting base, and the front surface of the mounting plate has a through groove extending to its rear surface.

[0007] As a preferred technical solution of this application, a warning sign is rotatably connected inside the through groove, and yellow reflective strips and red reflective strips are respectively provided on the front and rear surfaces of the warning sign.

[0008] As a preferred technical solution of this application, the left and right sides of the warning sign are respectively fixedly connected to rotating shafts, and the front side surface of the mounting plate is provided with a clearance groove extending to its rear side surface.

[0009] As a preferred technical solution of this application, a toothed plate is fixedly connected to the front surface of the baffle, and the front end of the toothed plate extends to the front surface of the mounting plate through a relief groove.

[0010] As a preferred technical solution of this application, the toothed plate and the relief groove are movably connected, and the rotating shaft rotates through the interior of the relief groove.

[0011] As a preferred technical solution of this application, a gear is fixedly connected to one end of the rotating shaft located inside the relief groove, and the gear meshes with the gear plate.

Both the stabilizing plate 11 and the connecting lugs 9 are provided with connecting pins 12. The mounting base 1 is equipped with a warning device. With the help of the metal chain mesh 5 and the elastic metal plate 8, a double buffer against the impact of falling rocks can be achieved, thereby effectively reducing the direct impact of falling rocks on the baffle 2, ensuring the stability of the baffle 2's own structure, and also preventing the device from tilting due to the direct action of the falling rock impact force on the main body.

[0029] Example 2

[0030] The rockfall safety warning device for mining provided in Example 1 has been further optimized, specifically, as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the warning device includes a mounting plate 13, which is fixedly connected between two vertical plates of the mounting base 1. A through groove 14 extending to the rear surface of the mounting plate 13 is formed on its front surface. A warning sign 15 for warning purposes is rotatably connected inside the through groove 14. Yellow and red reflective strips are respectively provided on the front and rear surfaces of the warning sign 15. Rotating shafts 16 are fixedly connected to the left and right surfaces of the warning sign 15. A clearance groove 17 extending to the rear surface of the mounting plate 13 is formed on its front surface. A toothed plate 18 for power transmission is fixedly connected to the front surface of the baffle 2. The front end of the toothed plate 18 extends to the front surface of the mounting plate 13 through the clearance groove 17. On the surface, the toothed plate 18 and the relief groove 17 are movably connected. The rotating shaft 16 rotates through the interior of the relief groove 17. One end of the rotating shaft 16 located inside the relief groove 17 is fixedly connected to a gear 19 for converting linear power into rotation. The gear 19 meshes with the toothed plate 18. A vibration sensor 20 is fixedly connected to the front surface of the mounting plate 13. A pressure sensor 21 is fixedly connected to the left surface of the right vertical plate of the mounting base 1. After a rockfall occurs, different signals can be emitted according to small rockfalls (vibration sensor 20) and large or piled rockfalls (pressure sensor 21). At the same time, the automatic reversal of the warning sign 15 can also actively remind the on-site staff to be careful of falling rocks.

[0031] Both the vibration sensor 20 and the pressure sensor 21 are connected to the signal transmitting device, which can send signals to the control room.

[0032] The usage process of the rockfall safety warning device for mining provided by this utility model is as follows:

[0033] When using this warning device, first move the device to the designated area, then fix the stabilizing plate 11 and the connecting lug 9 using the connecting pin 12. When a rockfall occurs, the rock will first come into contact with the metal chain mesh 5 along the slope, and the metal chain mesh 5 will absorb the impact of the rockfall. If the rockfall is small, the metal chain mesh 5 alone can completely absorb the impact without directly impacting the baffle 2. The resulting vibration will be transmitted to the mounting base 1, and then detected by the vibration sensor 20, which will send the vibration signal to the control room to indicate that a rockfall has begun. When the rockfall is large and the metal chain mesh 5 cannot completely absorb the impact, the mounting frame 4 and the connecting rod 3 will simultaneously... The movement of the baffle 2 causes it to move, which in turn compresses the elastic metal plate 8. The deformation of the elastic metal plate 8 further absorbs the impact. After the movement of the baffle 2, it comes into contact with the pressure sensor 21, which then sends a signal of a large rockfall to the control room again. At the same time, the movement of the baffle 2 also causes the toothed plate 18 to move. When the toothed plate 18 moves, it meshes with the gear 19, so the gear 19 rotates synchronously. The rotation of the gear 19 drives the rotating shaft 16 to rotate synchronously. When the rotating shaft 16 rotates, it causes the warning sign 15 to reverse, thereby exposing the red reflective strip on the back of the warning sign 15, reminding the staff that a large rockfall has occurred and to pay attention to safety.
