The reinforcement plate 6 includes a symmetrical first half 61 and a second half 62, which are mounted on the telescopic ends of the telescopic cylinder 31 and the first telescopic rod 32. The first half 61 and the second half 62 are connected to form a whole by bolts. The reinforcement plate 6 is also connected to the telescopic ends of the telescopic cylinder 31 and the second telescopic rod 52 by bolts.

[0031] Reference Figure 1At least two groups of stabilizing components 5 are provided. In this embodiment, two groups of stabilizing components 5 are optimally provided. Each group of stabilizing components 5 includes two stabilizing components 5, and the two groups of stabilizing components 5 are respectively provided on both sides of the width direction of the base plate 1; the stabilizing component 5 includes an extension plate 51 and a second telescopic rod 52, the extension plate 51 is movably mounted on the board wall of the base plate 1 along the horizontal direction, one end of the second telescopic rod 52 is movably mounted on the board wall of the extension plate 51, and the other end of the second telescopic rod 52 is movably mounted on the board wall of the reinforcement plate 6 close to the first telescopic rod 32.

[0034] Reference Figure 1 and Figure 2 The extension plate 51 is rotatably connected to the wall of the base plate 1 through a rotating shaft. The rotation axis of the extension plate 51 and the base plate 1 is in a vertical state. The rotation axis of the extension plate 51 and the base plate 1 is consistent with the rotation axis of the kit 8 and the connecting member 7, that is, the stabilizing component 5 can be rotated around the vertical axis, so that the stabilizing component 5 can be rotated to a suitable position according to the actual working environment to support the supporting component 3.

The side of the supporting plate 9 facing away from the telescopic cylinder 31 is connected to the roof 4. The setting of the supporting plate 9 increases the effective area of the telescopic cylinder 31 on the roof 4, so that the roof 4 has a better supporting effect on the coal mine tunnel.

[0039] The implementation principle of the utility model of a coal mine support pressure detection device is:

[0040] The bottom plate 1 with the detector 2 installed is placed at the position to be supported in the coal mine tunnel, and the telescopic cylinder 31, the first telescopic rod 32, the supporting plate 9 and the top plate 4 are fixedly installed.
