[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Combined with appendix Figure 1-3 This utility model provides a safety support component for coal mines, including a support frame 1 and two legs 2. Two legs 2 are fixedly connected to both ends of the support frame 1. A support plate 12 is provided at the lower end of each leg 2. The support plate 12 is connected to the upper end of the support frame 1 via a connecting plate 11. The support frame 1 has sliding grooves 13 on both sides of the support plate 12. A sliding plate 3 is slidably connected to the sliding groove 13. A sleeve 31 is provided at the upper end of the sliding plate 3. A buffer spring 32 is fixedly connected to the sliding plate 3 inside the sleeve 31. A buffer column 33 is slidably connected to the upper end of the buffer spring 32 inside the sleeve 31. An extension plate 34 is fixedly connected to the upper end of the buffer column 33. The support plate 12 and the extension plate 34 are connected to the upper end of the sleeve 31. Each of the expansion plates 34 is equipped with a buffer pad at the top. The upper end of the buffer pad is arc-shaped. During use, the expansion plate 34 can be slid out of the support frame 1 according to the actual situation of the roadway to adapt to different support needs. Specifically, the user pulls down the adjustment mechanism 4 and slides the expansion plate 34 outward, so that the slide plate 3 slides along the slide groove 13. The buffer pad at the top of the expansion plate 34 slides out from under the support plate 12. Under the action of the buffer spring 32, the expansion plate 34 is pushed upward and contacts the bottom of the roadway to support and protect it. To a certain extent, it can adapt to changes in the height of the roadway and is also convenient to adjust the support area of ​​the support components according to the actual situation, thereby improving the stability of the support.

[0023] Combined with appendix Figure 1-4 An adjustment mechanism 4 is provided on one side of the extension plate 34. Two adjustment mechanisms 4 are symmetrically arranged at both ends of the slide plate 3. The adjustment mechanism 4 includes a connecting cylinder 41, an adjustment rod 42, and a pull handle 43. The height of the sleeve 31 is lower than the height of the connecting plate 11. The connecting cylinder 41 is located on one side of the extension plate 34. The adjustment rod 42 is slidably connected to the connecting cylinder 41 through an adjustment spring. The pull handle 43 is fixedly connected to the lower end of the adjustment rod 42. When the extension plate 34 needs to be pulled outward, the adjustment handle is pulled to move the extension plate 34 outward, so that it slides out from under the support plate 12. When the extension plate 34 needs to be stored, the adjustment handle is pulled down so that the extension plate 34 is lower than the height of the support plate 12. Then, the adjustment rod 42 is used to push the extension plate 34 towards the slide groove 13 to complete the storage of the extension plate 34. Then, the adjustment handle is released so that the adjustment rod 42 enters the connecting cylinder 41 under the action of the adjustment spring, so as to avoid the adjustment handle being too low and obstructing the movement of personnel.

[0024] The working principle of this application is as follows:

[0025] In use, the extension plate 34 can be slid out of the support frame 1 according to the actual conditions of the roadway to adapt to different support needs. Specifically, the user pulls the adjustment handle to move the extension plate 34 outward, so that it slides out from under the support plate 12. The slide plate 3 slides along the slide groove 13, and the upper buffer pad of the extension plate 34 slides out from under the support plate 12. Under the action of the buffer spring 32, the extension plate 34 is pushed upward and contacts the bottom of the roadway, providing support and protection. To a certain extent, it can adapt to changes in roadway height and is also convenient to adjust the support area of ​​the support components according to the actual situation, thereby improving the stability of the support.

[0026] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
