[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0026] like Figures 1-5 As shown, a coal mine tunneling support device includes a top support plate 1. Several evenly distributed buffer mechanisms 2 are fixedly connected to the upper side of the top support plate 1. A rubber pad 3 is fixedly connected to the upper side of the top support plate 1. Two adjusting mechanisms 4 distributed in front and behind are fixedly connected to the top inner side of the top support plate 1 near the front and rear sides. Two second protective frames 5 distributed in front and behind are fixedly connected to the lower side of the top support plate 1 near the front and rear sides. The second protective frames 5 are located on the side where the two adjusting mechanisms 4 are far apart from each other.

[0027] The buffer mechanism 2 includes a buffer plate 21. Several rectangularly distributed buffer springs 22 are fixedly connected to the lower side of the buffer plate 21. The lower side of the buffer springs 22 is fixedly connected to the upper side of the top support plate 1. A rigid protective platform 23 is fixedly connected to the upper side of the top support plate 1, and the buffer springs 22 are located inside the rigid protective platform 23. Flexible pads are fixedly connected to the upper side of the buffer plate 21 and the outer side of the rigid protective platform 23.

[0028] It should be noted that the buffer spring 22 is an existing technology and will not be described in detail here. The buffer spring 22 is used to buffer the impact on the buffer plate 21. The rigid protective platform 23 is used to protect the buffer spring 22, so that when it falls on the outside of the rigid protective platform 23, it will not slip to the inside of the buffer spring 22. At the same time, the flexible pads on the buffer plate 21 and the rigid protective platform 23 reduce the wear caused by the gravel. Meanwhile, the gravel falling under the buffer plate 21 is small, so the rubber pad 3 is able to buffer these gravel, and also avoids wear on the upper side of the top support plate 1.

[0029] like Figure 3 As shown, a rubber sleeve 24 is fixedly connected to the upper side of the rigid protective platform 23 and the lower side of the buffer plate 21 near the edge.

[0030] It should be noted that the rubber sleeve 24 is used to seal the gap between the rigid protective platform 23 and the buffer plate 21, without affecting the movement of the buffer plate 21.

[0031] like Figure 3 As shown, the rigid protective platform 23 has an obtuse-angled triangle shape on both sides.

[0032] It should be noted that the shape of the rigid protective platform 23 ensures that when gravel falls on the side of the rigid protective platform 23, the gravel will not accumulate on the upper side of the top support plate 1 due to the presence of the rigid protective platform 23.

[0033] like Figure 2 , Figure 4 As shown, the adjustment mechanism 4 includes a first protective frame 41. Two first telescopic rods 42 are fixedly connected to the inner sides of the left and right walls of the first protective frame 41. The upper side of the first telescopic rods 42 is fixedly connected to the inner top of the top support plate 1 near the front and rear sides. Several horizontally distributed casters 43 are rotatably connected to the lower side of the first protective frame 41. Several horizontally distributed stabilizing components 44 are fixedly connected to the side of the first protective frame 41 away from the second protective frame 5 near the bottom.

[0034] It should be noted that the first telescopic rod 42 is an electric push rod or a hydraulic push rod, which can drive the top support plate 1 to move up and down. The second protective frame 5 and the first protective frame 41 are closely attached to each other. The second protective frame 5 is used to fill the gap between the top support plate 1 and the first protective frame 41 when the top support plate 1 rises.

[0035] like Figure 4 , Figure 5 As shown, the stabilizing component 44 includes a second telescopic rod 441. The outer side of the second telescopic rod 441 is fixedly connected to the bottom of the first protective frame 41 on the side away from the second protective frame 5. An attitude gyroscope 442 is movably mounted on the upper side of the second telescopic rod 441. A support plate 443 is rotatably connected to the lower side of the second telescopic rod 441. A plug rod 444 is fixedly connected to the middle of the lower side of the support plate 443.

[0036] It should be noted that the second telescopic rod 441 is an electric push rod or a hydraulic push rod, which relies on the attitude gyroscope 442 to detect its own attitude, thereby causing the support plate 443 to move up and down, so that the attitude of the device is as stable as possible.

[0037] like Figure 5 As shown, two tension springs 445 are fixedly connected between the upper side of the support plate 443 near the left and right sides and the outer side of the movable part of the second telescopic rod 441.

[0038] It should be noted that the tension spring 445 pulls the support plate 443 to prevent the support plate 443 from rotating or swinging arbitrarily when it is in a suspended state.

[0039] like Figure 5 As shown, two elastic sleeves 446 are fixedly connected between the upper side of the support plate 443 near the left and right sides and the outer side of the movable part of the second telescopic rod 441, and the tension spring 445 is located inside the elastic sleeve 446.

[0040] It should be noted that the elastic sleeve 446 is used to protect the tension spring 445 and prevent external debris from falling into the tension spring 445 and affecting its operation.

[0041] The working principle of this utility model is as follows: First, the buffer spring 22 is existing technology and will not be described in detail here. The buffer spring 22 is used to buffer the impact on the buffer plate 21. The rigid protective platform 23 is used to protect the buffer spring 22, so that when it falls on the outside of the rigid protective platform 23, it will not slip to the inside of the buffer spring 22. At the same time, the flexible pads on the buffer plate 21 and the rigid protective platform 23 reduce the wear caused by the gravel. In addition, the gravel falling under the buffer plate 21 is small, so the rubber pad 3 is able to buffer these gravel, and also avoid the wear caused to the upper side of the top support plate 1. The shape of the rigid protective platform 23 ensures that when the gravel falls on the side of the rigid protective platform 23, it will not cause the gravel to accumulate on the upper side of the top support plate 1 due to the presence of the rigid protective platform 23. Through the shielding of the rigid protective platform 23 and the rubber sleeve 24, the buffer spring 22 is protected. Relying on the shielding of the rubber pad 3, the part of the upper side of the top support plate 1 located between the buffer plates 21 is protected. The first telescopic rod 42 is an electric or hydraulic push rod that can move the top support plate 1 up and down. The second protective frame 5 is close to the first protective frame 41 and is used to fill the gap between the top support plate 1 and the first protective frame 41 when the top support plate 1 rises. The second telescopic rod 441 is an electric or hydraulic push rod that uses the attitude gyroscope 442 to detect its own attitude and thus move the support plate 443 up and down, so that the attitude of the device is as stable as possible. The first telescopic rod 42 moves the top support plate 1 up and down to adapt to mines of different heights. The second telescopic rod 441 moves the support plate 443 up and down to adapt to uneven mine ground, thus enabling the device to adapt to various mine environments.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
