[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] Please see Figures 1 to 4 This utility model provides a technical solution: a safety support structure for coal mining, including symmetrically arranged support mechanisms 1 and crossbeam mechanisms 2 arranged between the symmetrically arranged support mechanisms 1;

[0023] The crossbeam mechanism 2 consists of strut A21, adjusting component 22, and strut B23. Adjusting component 22 is positioned between strut A21 and strut B23. The crossbeam mechanism 2 adjusts the lateral dimensions of the safety support structure. Adjusting component 22 consists of adjusting column A221, adjusting column B222, and adjusting column C223. Adjusting column A221 is positioned on one side of adjusting column B222, and adjusting column C223 is positioned on the other side. Through the designed electric lifting column 11 and adjusting component 22, the problem of the original fixed safety support structure used to support coal mine roadways during coal mining, which could not be adjusted according to the actual conditions of the roadway, is improved. The problem is that the width and height of the safety support structure are adjustable, allowing for flexible adjustment according to different coal mine roadway dimensions, increasing usability. A telescopic assembly is installed between one side of the adjusting column A221 and adjusting column B222. This telescopic assembly consists of a movable groove 2211, a movable block 2212, a threaded groove 2213, and a threaded column 2214. The movable groove 2211 is located at the end of adjusting column A221, the movable block 2212 is fixed to one end of adjusting column B222, the threaded groove 2213 is located at the end of the movable block 2212, and the threaded column 2214 is fixed to the end of the movable groove 2211. The part is inserted into the inner side of the threaded groove 2213 and is threaded. Through threaded adjustment, the telescopic position of the crossbeam mechanism 2 becomes more flexible. The threaded column 2214 has a cylindrical structure. The surface of the movable block 2212 is in contact with the inner wall of the movable groove 2211. The movable block 2212 has a cylindrical structure. A limit assembly is provided between the other side of the adjusting column B222 and the adjusting column C223. The limit assembly consists of a limit seat 2221 and a limit groove 2222. The limit groove 2222 is located at the end of the adjusting column C223, and the limit seat 2221 is located inside the limit groove 2222. The bottom end of the limit seat 2221 is fixed to the other side of the adjusting column B222. The support mechanism 1 consists of an electric lifting column 11 and a column 12. The electric lifting column 11 is located at the bottom of the column 12. A drive motor is installed inside the electric lifting column 11. A lead screw is installed at the end of the drive motor and inside the electric lifting column 11. The drive motor drives the lead screw to raise and lower the electric lifting column 11. A Hall sensor is installed inside the electric lifting column 11. The built-in Hall sensor plays a position detection role. During the lifting process, it can sense the position information of the column and feed it back to the control system. When the support mechanism 1 reaches the preset position, the Hall sensor sends a signal, and the drive motor stops working, realizing accurate positioning and ensuring a smooth lifting process and avoiding overshoot.

[0024] In this embodiment, preferably, diagonal braces 3 are provided at the connection angle between the symmetrically arranged support mechanism 1 and the crossbeam mechanism 2. Bolts pass through the connection points of the two ends of the diagonal braces 3 to the connection points of the crossbeam mechanism 2 and the diagonal braces 3, respectively. The diagonal braces 3 support the angle between the support mechanism 1 and the crossbeam mechanism 2, ensuring the support effect of the safety support structure during use.

[0025] The working principle and usage process of this utility model are as follows: During coal mining, a support structure is installed to support the coal mine, ensuring the stability and safety of the roadway during mining. During the installation of the safety support structure, the length of the crossbeam mechanism 2 is adjusted according to the transverse dimensions of the coal mine roadway. By rotating the adjusting column B222, the movable block 2212 is driven to rotate inside the movable groove 2211. The threaded column 2214 is threadedly connected to the threaded groove 2213, which drives the limiting seat 2221 to rotate inside the limiting groove 2222. This causes the distance between the adjusting column B222 and the adjusting column A221 to expand and contract, thereby adjusting the length of the crossbeam mechanism 2. Then, the adjusted crossbeam mechanism 2 is assembled with the support mechanism 1. Next, the electric lifting column 11 works through the drive motor, which converts electrical energy into mechanical energy to provide the initial power for the lifting action. Through the screw drive, the electric lifting column 11 is driven to lift and lower, thereby adjusting the overall height of the support mechanism 1. This allows the safety support structure to be adapted to the dimensions of the coal mine roadway, providing a safe working space for personnel and equipment.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
