Description

Technical Field

[0001] This application relates to the field of mine safety technology, specifically to a mine tunnel support alarm device for mine safety. Background Technology

[0002] Mine safety is paramount. Mines are sites for extracting ore or producing mineral raw materials. Mining is a high-risk industry, and safety must be a top priority. Major factors affecting mine safety include landslides, collapses, blasting, mechanical injuries, falls from heights, occupational hazards, vehicle accidents, and electrical injuries. Mines must develop corresponding safety precautions for each hazard and establish appropriate emergency response mechanisms to ensure timely handling of accidents and minimize personal injury and property damage. Therefore, mine safety alarm devices are necessary for warning purposes during actual mining operations.

[0003] Patent CN218585447U discloses a mine tunnel support alarm device for mine safety. This device involves fixing side plates to the inner walls of both sides of the mine tunnel and fixing a fixed ramp to the upper end of the tunnel. When the mine tunnel collapses, the pressure at the upper end forces the fixed ramp downwards, simultaneously pressing down the support rod. This increases the air pressure inside the warning pressure tank, which is then fed back to the linkage device via a connecting pipe. The linkage device then triggers an alarm. Furthermore, when the mine tunnel collapses, the cooperation between the fixed ramp and the side plates forms a frame, supporting the tunnel and slowing its collapse, thus facilitating the rapid escape of workers.

[0004] However, the side plates of the mine tunnel support alarm devices used for mine safety mentioned above can only be adapted to mine tunnels of a single size to achieve the purpose of fixing the alarm devices. They cannot be adapted to mine tunnels of different widths, and the applicable mining scenarios are limited, resulting in low cost-effectiveness. Utility Model Content

[0005] To address the shortcomings of existing technologies, this application provides a mine tunnel support alarm device for mine safety, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this application provides the following technical solution: a mine tunnel support alarm device for mine safety, comprising an alarm mechanism and a support mechanism for providing upward support force to the mine tunnel. The alarm mechanism is provided with a fixing mechanism suitable for mine tunnels of different shapes on its side. The fixing mechanism includes an outer tube and a fixing frame. The outer tube is provided on the left and right sides of the alarm mechanism. The fixing frame is connected to one end of the outer tube. The support mechanism is provided above the alarm mechanism.

[0007] By adopting the above technical solution, the movement of the outer tube can drive the movement of the fixing frame to insert the fixing rod into the inner wall of the mine, thereby fixing the alarm device inside the mine. This method is suitable for mines of different sizes.

[0008] Preferably, the fixing mechanism further includes a rotating hole and a rotating rod. The rotating hole is opened on the left and right sides of the alarm mechanism. The rotating rod is rotatably connected to the inner wall of the rotating hole. One end of the rotating rod is connected to a rotating plate, and the other end of the rotating rod is connected to an adjusting screw. The side of the adjusting screw is threadedly connected to the inner wall of the outer tube.

[0009] By adopting the above technical solution, the rotation of the rotating plate can drive the rotating rod inside the rotating hole to rotate, the rotation of the rotating rod can drive the adjusting screw to rotate, and the rotation of the adjusting screw can drive the outer tube to move, which facilitates the fine adjustment of the position of the fixed frame.

[0010] Preferably, the fixing mechanism further includes a limiting plate and a limiting rod. The limiting plate is connected to one side of the top of the outer tube, and a limiting hole is opened on the upper right side of the limiting plate. The limiting rod is connected to the upper side of the alarm mechanism, and the side of the limiting rod is slidably connected to the inner wall of the limiting hole.

[0011] By adopting the above technical solution, the sliding connection between the limiting hole in the limiting plate and the limiting rod can be used to convert the rotation of the adjusting screw that drives the outer tube to rotate into horizontal movement, thereby improving the stability of the outer tube during movement.

[0012] Preferably, the alarm mechanism includes a protective frame and a lower telescopic tube. The protective frame has rotating holes on both the left and right sides, and limiting rods are connected to the upper part of both the left and right sides of the protective frame. The top of the lower telescopic tube is connected to the bottom of the protective frame, and a base plate is connected to the bottom of the lower telescopic tube.

[0013] By adopting the above technical solution, the lower telescopic tube between the protective frame and the base plate can be used to provide directional guidance for the positional adjustment of the base plate, and maintain the connection between the base plate and the protective frame.

[0014] Preferably, the alarm mechanism further includes a position sensor and an alarm, the position sensor being connected to the front top of the protective frame and the front bottom of the protective frame respectively, and the right side of the alarm being connected to the right side of the inner wall of the protective frame.

[0015] By adopting the above technical solution, position sensors can be used to monitor the position changes of the base plate and support frame in real time, and alarms can be issued based on changes in the values ​​recorded by the position sensors, thereby reducing losses caused by mine collapses.

[0016] Preferably, the support mechanism includes a bidirectional screw and a turntable. The two ends of the bidirectional screw are rotatably connected to the upper left and right sides of the inner wall of the protective frame, respectively. The left and right sides of the surface of the bidirectional screw are threaded with internal threaded frames, and the turntable is connected to the center of the surface of the bidirectional screw.

[0017] By adopting the above technical solution, the rotation of the turntable can drive the rotation of the bidirectional screw, and the rotation of the bidirectional screw can drive the internal thread frame to move horizontally, ensuring that the height adjustment of the support frame is a linear movement, and avoiding insufficient upward support due to uneven force on both sides of the support frame.

[0018] Preferably, the support mechanism further includes a slide groove and a push plate. The slide groove is opened on the left and right sides of the top of the protective frame. The inner wall of the slide groove is slidably connected to the side of the internal thread frame. The bottom of the push plate is hinged to the top of the internal thread frame. A hinge frame is hinged above the push plate. A fixing plate is connected to the top of the hinge frame.

[0019] By adopting the above technical solution, the sliding connection between the slide and the internal thread frame can be used to avoid the internal thread frame from tilting when it moves, provide guidance for the movement direction of the internal thread frame, and ensure that the push plate has enough room for movement by using the hinge frame, and connect the two hinge frames by using the fixing plate.

[0020] Preferably, the support mechanism further includes a support frame and an upper telescopic tube, the bottom of the support frame being connected to the top of the fixed plate, the top of the upper telescopic tube being connected to the center of the bottom of the fixed plate, and the bottom of the upper telescopic tube being connected to the center of the top of the protective frame.

[0021] By adopting the above technical solution, the support frame can provide upward support to the top of the mine wall, and the telescopic movement of the upper telescopic tube can be used to prevent the push plate from tilting when not manually adjusted, thus ensuring the stability of the relative position of the push plate.

[0023] 1. The mine safety support alarm device for mines, through the setting of a fixed mechanism, the rotation of the rotating plate drives the rotating rod inside the rotating hole to rotate, the rotation of the rotating rod drives the adjusting screw to rotate, and the rotation of the adjusting screw drives the fixed frame at one end of the outer tube to move and insert into the inner wall of the mine. At the same time, it causes the limiting hole opened in the limiting plate to slide on the surface of the limiting rod, which facilitates the adjustment of the size of the alarm device, expands the usable mine size of the alarm device, increases the number of times the alarm device can be used, and improves the cost performance of the alarm device.

[0024] 2. The mine safety support alarm device for mines, through the setting of a support mechanism, rotates a turntable to rotate a bidirectional screw, the rotation of the bidirectional screw drives the internal threaded frame to move in opposite directions within the slide groove, the movement of the internal threaded frame drives the push plate to move and push the fixed plate at the top of the hinged frame to move upward, the upward movement of the fixed plate drives the support frame to move upward and insert into the inner wall of the mine, and at the same time drives the upper telescopic tube to extend, ensuring that the support mechanism supports upward while improving the fit between the support frame and the inner wall of the mine, thereby improving the real-time performance of the alarm device.
