The guide block can assist the bracket in accurately positioning on the inclined mine tunnel. The groove, connecting plate, fixing bolt and connecting block constitute a stable basic connection structure.

The installation mechanism is composed of movable bolts, connecting rods, tail plates, support plates, connecting grooves and a first connecting shaft. The movable bolts and connecting rods can movably connect the bracket to the mine tunnel wall. The tail plate and support plate cooperate with the connecting groove and the first connecting shaft to achieve a stable connection with the roof mechanism. This mechanism can enable the bracket to be firmly installed in the mine tunnel, enhance the stability of the bracket in a complex mine tunnel environment, and effectively resist the displacement risk caused by mine tunnel pressure.

[0013] 2. The roof mechanism consists of a first connecting frame, a second connecting shaft, a movable side guard plate, a second connecting frame, a third connecting shaft, a push plate, a mounting slot, a first air pump, a first gas rod, a first connecting ring, a first mounting seat, a second air pump, a second gas rod, a second connecting ring, a second mounting seat, a main rib plate, and a steel plate. The first connecting frame and second connecting shaft form the basic framework. The movable side guard plate can flexibly adjust its protection range. The drive structure composed of the first air pump and first gas rod can push the push plate, dynamically supporting it according to changes in roof pressure.

In inclined mine tunnels, the mine tunnel environment is complex and the installation space is limited. The guide block 101 can assist the operator to quickly align the support The installation position reduces repeated adjustments during the installation process, which not only improves the installation efficiency but also reduces the installation difficulty, ensuring that the bracket can be accurately installed in the predetermined position, laying the foundation for subsequent work, and the groove 102 provides installation space for components such as the connecting plate 103. The fixing bolt 104 can firmly fix the connecting block 105 in the appropriate position through the rotation connection with the connecting plate 103, so that the base unit can withstand the huge pressure transmitted from the upper top plate mechanism 3, as well as the downward force and lateral force generated by the slope in the inclined mine tunnel, ensuring that the bracket remains stable during operation without loosening or displacement, effectively ensuring the support reliability of the bracket, the multi-section linkage hydraulic telescopic rod 106 fixed on the upper surface of the connecting block 105 is the key power source for realizing multi-angle adjustment of the hydraulic support. In the inclined mine tunnel, the slope and shape of the mine tunnel at different positions are different. The multi-section linkage hydraulic telescopic rod 106 can achieve a wide range of high-precision angle adjustment through the coordinated extension and retraction of the multi-section hydraulic rod.

[0025] Preferably, the mounting mechanism includes a movable bolt 2, which is arranged on the left and right sides of the base unit 1, and the outer wall of the movable bolt 2 is movably connected to the connecting rod 201, and the upper surface of the connecting rod 201 is movably connected to the tail plate 202 and the support plate 203, and the tail plate 202 and the support plate 203 are both provided with a connecting groove 204, and the interior of the connecting groove 204 is movably connected to the first connecting shaft 205, and the outer wall of the first connecting shaft 205 is movably connected to the fixing block 206, and the connecting groove 204 and the first connecting shaft 205 are connected to the top plate mechanism 3. The movable bolts 2 are arranged on the left and right sides of the base unit 1, and are movably connected to the connecting rod 201 through their outer walls, so that the connecting rod 20 1 can be rotated with the movable bolt 2 as the axis, and the angle of the connecting rod 201 can be adjusted according to the actual situation of the mine tunnel, so that the tail plate 202 and the support plate 203 can better fit the mine tunnel wall. In addition, in the inclined mine tunnel, the shape of the mine tunnel wall is irregular. Through the cooperation of the movable bolt 2 and the connecting rod 201, it can adapt to different mine tunnel wall surfaces and ensure the stability of the bracket installation. Secondly, the connecting groove 204 opened inside the tail plate 202 and the support plate 203 and the first connecting shaft 205 of the movable connection can be connected to each other with the top plate mechanism 3. The connecting groove 204 provides a movable space for the first connecting shaft 205, so that the tail plate 202 and the support plate 203 can be fine-tuned within a certain range.

[0026] Preferably, the top plate mechanism 3 includes a first connecting frame 301, the first connecting frame 301 is arranged inside the first connecting frame 301, one side of the first connecting frame 301 is rotatably connected to the second connecting shaft 302, the outer wall of the second connecting shaft 302 is movably connected to the movable side guard plate 303, one side of the movable side guard plate 303 is fixedly connected to the second connecting frame 304, one side of the second connecting frame 304 is movably connected to the third connecting shaft 305, the outer wall of the third connecting shaft 305 is movably connected to the push plate 306, the lower surface of the movable side guard plate 303 is provided with a mounting groove 307, the interior of the mounting groove 307 is fixedly connected to The first air pump 308 is movably connected to the first air rod 309 on one side of the first air pump 308, and the output end of the first air rod 309 is fixedly connected to the first connecting ring 3010.

The lower surface of the first connecting frame 301 is fixedly connected to the second air pump 3012, and the second air pump 3012 is movably connected to the second air rod 3013 on one side. The output end of the second air rod 3013 is fixedly connected to the second connecting ring 3014, and the left and right sides of the second connecting ring 3014 are movably connected. The second mounting base 3015 is connected, and the second mounting base 3015 is connected to the movable side guard plate 303. Two pairs of main ribs 3016 are fixedly connected to the interior of the top plate mechanism 3. One side of the main ribs 3016 is fixedly connected to a plurality of steel plates 3017. When the pressure on the side wall of the mine tunnel changes or local deformation occurs, the movable side guard plate 303 can adjust its angle in time under the action of the second connecting shaft 302, and fit the side wall of the mine tunnel for effective support.

The main ribs 3016, as the main force-bearing components, can withstand the huge pressure from the roof and side walls of the mine tunnel, and the steel plates 3017 further disperse the stress to prevent local deformation of the structure.

[0027] The movable mechanism 6 includes a movable block 601, and the position of the movable mechanism 6 is set on the lower surface of the support plate 203, and the position of the movable block 601 is set in the middle of the movable mechanism 6.

The outer wall of the buffer spring 603 is movably connected to a sleeve 604, and the sleeve 604 is connected to the steel plate 3017. When the bracket is vibrated, the buffer spring 603 will be compressed or stretched, and the vibration energy will be converted into elastic potential energy of the spring, and then slowly released, thereby reducing the impact of the vibration on the bracket structure and extending the service life of the bracket. The telescopic rod 602 is movably connected to the movable block 601, so that the movable mechanism 6 has a certain degree of telescopic and movable ability. In an inclined mine tunnel, the shape and size of the mine tunnel may change with the mining process, or the mine tunnel may have slight deformation due to geological movement. 602 can be telescopically adjusted according to these changes, so that the bracket can better adapt to the complex environment of the mine tunnel.

When the bracket needs to work on inclined planes at different angles, the movable block 601 can allow the telescopic rod 602 and the buffer spring 603 to be adjusted accordingly to ensure that the movable mechanism 6 can always play its buffering and supporting role, thereby improving the adaptability and work efficiency of the bracket under various working conditions.

The slide groove 4 is arranged at the bottom end of the lower surface of the base unit 1, providing a precise moving track for the movable rod 402. During the mining process, as the mining area advances, the hydraulic support needs to continuously adjust its position. At this time, the movable rod 402 can slide smoothly along the slide groove 4, driving the connecting seat 403 and the entire support to move. Secondly, the third mounting seat 400 fixedly connected inside the slide groove 4 1. It provides a stable connection foundation for the movable rod 402. The third mounting seat 401 is movably connected to the movable rod 402, which not only ensures that the movable rod 402 can move flexibly, but also ensures that it will not easily fall off the track during the movement, so that the hydraulic support can be accurately positioned after moving to the target position.

The cooperation of the ball 506 and the ball groove 507 enables the first fixed rod 505 to roll flexibly in the ball groove 507, greatly reducing the friction resistance. When the multi-section linkage hydraulic telescopic rod 106 is extended or retracted, the second guide rod 5010 is driven to move, and then the first fixed rod 505 is moved by the second fixed rod 508, the ball groove 507 and the ball 506.

When the external impact force is transmitted to the bracket, the buffer block 502 first buffers it to reduce the impact of vibration and impact force on other parts of the bracket and protect the bracket. The structure is not damaged, the service life of the bracket is extended, and a safer and more stable working environment is provided for workers in the mine. The combination of the first guide rod 503 and the first protective ring 504, and the second guide rod 5010 and the second protective ring 509, provides good protection and stability for the first guide rod 503 and the second guide rod 5010, and the first protective ring 504 and the second protective ring 509 can prevent debris, dust and other debris in the mine from entering the connection between the first protective ring 504 and the second protective ring 509, thereby avoiding wear and jamming caused by impurities and ensuring the smoothness of the adjustment process.
