[0029] Example:

[0030] Please combine Figure 1-8 ,

[0031] A high-stability, ultra-long supported roadway end support reinforcement system includes:

[0032] A base 01 is rotatably connected to a support shaft 09. An auxiliary mechanism is installed within the base 01. The base 01 is fixed, and the rotation of the support shaft 09 allows the support plate 02 to rotate. The support plate 02 is fixedly sleeved on the outer wall of the support shaft 09 and rotatably contacts the base 01, providing necessary support and stability. An adjustment mechanism is installed on the support plate 02, and its moving end is connected to the main support mechanism for necessary adjustments. The main support plate 15 is rotatably connected to the moving end of the support mechanism, and one side is connected to a secondary support mechanism. The main support plate 15 is connected to the top of the tunnel for support.

[0033] The adjustment mechanism includes a fixed block 04 fixedly connected to the support plate 02. A hydraulic cylinder 05 is fixedly connected to one side of the fixed block 04. A follower rod 03, which is hinged to each other, is fixedly connected to the output end of the hydraulic cylinder 05. A follower rod 43, which is hinged to each other, is rotatably connected to the middle of the follower rod 03. A drive shaft, which is rotatably connected to the main support mechanism, is connected to the hinge of the follower rod 43. Under the adjustment of the hydraulic cylinder 05, the moving end drives the follower rod 03 to move. At the same time, the main support mechanism moves due to the drive of the follower rod 43 and the drive shaft.

[0034] The main support mechanism includes: a follower plate 24, with a rolling ball embedded in its bottom that contacts the support plate 02; a spring 44 fixedly connected to the top of the follower plate 24; and a stabilizing block 23 slidably sleeved with the follower plate 24 at the other end of the spring 44. The stabilizing block 23 moves according to the drive shaft, and the follower plate 24 provides bottom support. At the same time, it works in conjunction with the hydraulic cylinder 206 to achieve stable bottom support. A rotating frame 22 is fixedly connected to the stabilizing block 23, and a hydraulic cylinder 21 rotatably connected to the main support plate 15 is rotatably connected in the middle. The height of the rotating frame 22 is adjusted by adjusting the rotating frame. One end of the hydraulic cylinder 206 is rotatably connected to the support plate 02, and the other end is rotatably connected to the rotating frame 22.

[0035] The auxiliary support mechanism includes: a hydraulic cylinder 17, which is rotatably connected to one side of the main support plate 15, and its output end is rotatably connected to a fixed frame 18. A rotating plate 14, which is rotatably connected to the main support plate 15, is rotatably fixed to one side of the fixed frame 18. The hydraulic cylinder 17 is adjusted as necessary to drive the fixed frame 18 and the rotating plate 14 to rotate to ensure the work needs. A rotating plate 12 is rotatably connected to one side of the rotating plate 14, and a hydraulic cylinder 26 is rotatably connected to one side of the rotating plate 12. The other end of the hydraulic cylinder 26 is rotatably connected to a hydraulic cylinder 11, which is rotatably connected to the rotating plate 12. A hydraulic cylinder 28, which is rotatably connected to the rotating plate 14, is rotatably connected to one side of the hydraulic cylinder 11. Through the adjustment of the hydraulic cylinder 26 and the hydraulic cylinder 28, the angle of the hydraulic cylinder 11 and the rotating plate 12 is adjusted to ensure the support angle of the safety mechanism 10. The safety mechanism 10 is connected to the output end of the hydraulic cylinder 11 and is in contact with the ground.

[0036] The safety mechanism 10 includes: a support block 31 with a guide ring 33 fixedly connected thereto, an elastic component 30 fixedly connected inside the guide ring 33, the other end of the elastic component 30 being fixedly connected to the output end of the hydraulic cylinder 11, the guide ring 33 being slidably sleeved with the output end of the hydraulic cylinder 11, a safety plate 29 rotatably connected to the support block 31, a safety plate 32 rotatably connected to one side of the safety plate 29, and a hydraulic cylinder 34 rotatably connected to the support block 31, with its other end rotatably connected to the safety plate 32. The support block 31 is in contact with the ground, and when the elastic component 30 reaches its limit, it provides support. At the same time, through the action of the hydraulic cylinder 34, the safety plate 32 rotates, thus protecting and supporting a certain space.

[0037] A convex block 13 is fixedly connected to one side of the rotating plate 12, and a concave block 20 is fixedly connected to the other side of the rotating plate 12. The concave block 20 and the convex block 13 cooperate with each other. A reinforcing plate 27, which is fixedly connected to the rotating plate 12, is fixedly connected to the lower side of the concave block 20. The connection is achieved through the support of the reinforcing plate 27 and the mutual connection between the concave block 20 and the convex block 13.

[0038] The auxiliary mechanism includes: a drive shaft 42, which is rotatably connected to the base 01, and its other end is connected to a gearbox 39. The output end of the gearbox 39 is connected to a transmission assembly 25, which is connected to the support shaft 09. An electromagnetic brake 40 that cooperates with the transmission assembly 25 is fixedly connected to one side of the base 01. The drive shaft 42 can drive the gearbox 39 to work through external transmission, and further work through the transmission assembly 25 to make the support shaft 09 rotate. A cable 37 is set inside the base 01, and a sensor 38 fixedly connected to the base 01 is set on one side of the cable. A guide groove 08 is set at the bottom of the base 01 and guides the cable.

[0039] A transport rail 35 is provided on one side of the base 01. A guide bar 36 that cooperates with the guide groove 08 is fixedly connected to one side of the transport rail 35. A control mechanism 45 is provided inside the support plate 02. The stable transport of the device is achieved by limiting the transport rail 35 and the guide bar 36.

[0040] Multiple threaded blocks 19 are threaded onto the main support plate 15. An addition box 47 is connected to the other side of the threaded block 19. A push plate 51 is slidably fitted inside the addition box 47. A trigger frame 48 is fixedly connected to the upper side of the push plate 51 and slidably fitted with the addition box 47. A hose 50 is connected to the upper side of the push plate 51, and the other end of the hose 50 is connected to an overflow hole 49 located on the addition box 47. A buffer plate 52 is fixedly connected to the lower side of the addition box 47. If necessary, the addition box 47 can be installed on the rotating plate 14. When the trigger frame 48 contacts the top, it drives the push plate 51 to descend, further allowing the coagulant in the addition box 47 to reach the roadway through the hose 50 and the overflow hole 49 for solidification and support, ensuring confinement. A coal conveying belt 41 is provided on one side of the base 01. A reinforcing rib 07 is fixedly connected inside the base 01. The support plate 02 adopts a triangular structure.

[0041] The implementation principle of this application embodiment is as follows:

[0042] During support installation, guided by transport rail 35, the base 01 moves to the designated position. Then, the support shaft 09 rotates, causing the main support plate 15 and the rotating plate 14 to rotate to the appropriate position. Hydraulic cylinder 05 then moves follower rod 03 and follower rod 43, which in turn moves the rotating frame 22. In conjunction with hydraulic cylinders 06 and 21, the main support plate 15 tilts, and hydraulic cylinder 21 lifts the main support plate 15, providing top support. Then, as needed, the rotating plate 14 is unfolded by hydraulic cylinder 4 17 and fixed frame 18 to increase the support area. According to the adjustment of hydraulic cylinder 7 28 and hydraulic cylinder 6 26, hydraulic cylinder 3 11 is moved to the designated position, so that safety mechanism 10 is lowered to support. During the support process, safety mechanism 10 unfolds safety plate 2 32 through the action of hydraulic cylinder 8 34, leaving a certain safety space to ensure subsequent safety. At the same time, the transport rail 35 is connected to the outside world, which can supply air or water in case of emergency, so as to achieve safety guarantee.
