[0058] A moving rod 5, wherein the moving rod 5 is fixed to the uppermost part of the inner side of the top frame 1;

[0059] An installation box 6, wherein the installation box 6 is slidably connected to the moving rod 5;

[0060] An alarm light 7, wherein the alarm light 7 is installed at the bottom of the installation box 6;

[0061] The top frame 1 and the upper arch frame 2 are both fixed by a fixing mechanism 100;

[0062] The warning light 7 is provided with a sensing feedback mechanism 400 for sensing the displacement of the moving rod 5 , and the sensing feedback mechanism 400 is used to send the sensing result to the warning light 7 .

[0063] In the embodiment of the utility model, when in use, the top frame 1 and the upper arch frame 2 are fixed to the mining entrance for support by the fixing mechanism 100. Since the top is subjected to the greatest force, when the top becomes loose, the curvature of the top frame 1 increases, thereby driving the moving rod 5 to move downward. At this time, the sensing feedback mechanism 400 in the installation box 6 senses that the displacement of the moving rod 5 reaches a predetermined value, thereby sending the result to the alarm light 7, causing the alarm light 7 to sound an alarm, reminding the mining team to perform repairs and maintenance to avoid safety hazards. At the same time, the sensing feedback mechanism 400 can also transmit the power of the displacement of the moving rod 5 to the support plate 4, so that the support plate 4 increases the supporting force on the top frame 1 and enhances the protective strength.

[0064] like Figure 4 As shown, as a preferred embodiment of the present utility model, the inductive feedback mechanism 400 includes:

[0065] A controller 20, wherein the controller 20 is installed in the installation box 6;

[0066] A limit sensor 21, wherein the limit sensor 21 is installed on the inner side of the installation box 6 away from the moving rod 5;

[0067] The second valve plate 22 is slidably disposed in the installation box 6 and fixedly connected to the moving rod 5 .

[0068] In the embodiment of the utility model, when in use, the moving rod 5 drives the second valve plate 22 to move, so that the second valve plate 22 moves to contact the limit sensor 21 and triggers the limit sensor 21, so that the limit sensor 21 transmits the signal to the controller 20, and then the controller 20 sends the judgment result to the alarm light 7, thereby achieving the effect of early warning alarm.

[0069] In one case of this embodiment, the inductive feedback mechanism 400 further includes a secondary stabilizing component for driving the support plate 4 to abut against the top frame 1, and the secondary stabilizing component includes:

[0070] A third connecting rod 25, wherein the third connecting rod 25 is fixed on the second valve plate 22;

[0072] The second connecting rod 24 is fixedly connected to the rotating shaft 23, one end of the second connecting rod 24 is rotatably connected to the third connecting rod 25, the other end of the second connecting rod 24 is slidably connected to the installation box 6, and one end of the second connecting rod 24 away from the third connecting rod 25 is fixedly connected to the support plate 4.

[0073] In this embodiment, when the moving rod 5 drives the second valve plate 22 to move downward, the second valve plate 22 drives the third connecting rod 25 to move, the third connecting rod 25 pulls the second connecting rod 24 to flip downward, and the other end of the second connecting rod 24 drives the support plate 4 to move upward, thereby strengthening the strength of the supporting top frame 1.

When the moving rod 5 moves, the power is converted into air pressure through the sensing feedback mechanism 400, which is then transmitted to the first mounting sleeve 11 through the connecting tube 8, thereby pushing the first valve plate 9 to move, and the first valve plate 9 drives the insertion rod 10 to move, thereby strengthening the supporting strength and increasing the protective performance.

[0082] like Figure 2 As shown, as another preferred embodiment of the present utility model, the one-way movable limiting unit 200 includes:

[0083] A second mounting sleeve 26, wherein the second mounting sleeve 26 is fixed on the first mounting sleeve 11;

[0084] A movable seat 12, wherein the movable seat 12 is slidably disposed on the inner wall of the second mounting sleeve 26, and a first inclined surface is disposed at one end of the movable seat 12 away from the inner wall of the second mounting sleeve 26;

[0087] A mounting plate 15, wherein the mounting plate 15 is mounted on one end of the movable seat 12 away from the inner wall of the second mounting sleeve 26;

[0088] The mounting plate 15 is provided with elastic limiting components 300 which are evenly distributed and limit the first inclined surface.

[0089] In the embodiment of the utility model, when the moving rod 5 moves, it is sensed by the induction feedback mechanism 400, thereby converting the power into air pressure, which is then transmitted to the first mounting sleeve 11 through the connecting pipe 8, thereby pushing the first valve plate 9 to move, the first valve plate 9 drives the insertion rod 10 to move, the first valve plate 9 drives the first connecting rod 14 to move, the first connecting rod 14 drives the moving seat 12 to move, the moving seat 12 squeezes the elastic limit assembly 300 and thus passes over the elastic limit assembly 300, when the moving seat 12 passes over the elastic limit assembly 300, the elastic force of the elastic limit assembly 300 is used to reset it, and the end face of the moving seat 12 is limited.

[0090] like Figure 3As shown, as another preferred embodiment of the present utility model, the elastic limiting component 300 includes:

[0095] In the embodiment of the utility model, when in use, the movable seat 12 moves to squeeze the second inclined surface, so that the stopper 18 drives the slider 17 to shrink into the slide groove 16. At this time, the second elastic member 19 is squeezed. When the movable seat 12 passes over the stopper 18, the elastic force of the second elastic member 19 drives the slider 17 and the stopper 18 to reset, so that the stopper 18 limits the end face of the movable seat 12 to prevent it from loosening and resetting.

[0096] The above-mentioned embodiment of the utility model provides a safety protection device for limestone mining. By setting a top frame 1, an upper arch frame 2, a lower arch frame 3, a support plate 4, a moving rod 5, an installation box 6, an alarm light 7, a fixing mechanism 100 and an inductive feedback mechanism 400, when in use, the top frame 1 and the upper arch frame 2 are fixed to the mining entrance for support by the fixing mechanism 100. Since the top is subjected to the greatest force, when the top becomes loose, the curvature of the top frame 1 increases, thereby driving the moving rod 5 to move downward. At this time, the inductive feedback mechanism 400 in the installation box 6 senses that the displacement of the moving rod 5 reaches a predetermined value, thereby sending the result to the alarm light 7, so that the alarm light 7 alarms, reminding the mining team to perform repairs and maintenance to avoid safety hazards. At the same time, the inductive feedback mechanism 400 can also transmit the power of the displacement of the moving rod 5 to the support plate 4, so that the support plate 4 increases the supporting force on the top frame 1 and enhances the protection strength.
