[0016] Beneficial effects
[0017] The present invention provides a temporary reinforcement mechanism for a tunnel collapse section, having the following beneficial effects:
[0018] For the temporary reinforcement mechanism for a tunnel collapse section, by forming a vertical groove in the vertical frame, a screw rod can be installed in the vertical groove, and the screw rod can rotate in the vertical groove. A connecting seat is installed on the screw rod in the vertical groove, and a sliding table is installed at one end of the connecting seat. The sliding table can move along the vertical frame following the connecting seat. When the arch frame moves to the sliding table, the position of the arch frame can be adjusted, so that the arch frame and the vertical frame can be adjusted, and the volume of the arch frame and the vertical frame can be reduced for convenient carrying and installation. During installation, the sliding table is lifted upward, and the arch frame can move to the position of the first guide groove of the vertical frame following the sliding table. Then, the vertical frame is pushed inward to make the vertical frame overlap with the arch frame. After the arch frame and the vertical frame are connected, they can support more stably. The arch frame and the vertical frame can be quickly adjusted to reinforce the tunnel, thus realizing efficient reinforcement and reducing the assembly time.
[0019] The temporary reinforcement mechanism for the collapsed section of the tunnel can install the bridging plate inside the inner groove opened in the sliding table. When the arch frame moves to the vertical frame, the bridging plate in the inner groove will move to the outside of the sliding table and then lap on the vertical frame. At this time, the sliding table will not move up and down, thus realizing the fixation of the sliding table. The sliding table can be located at the top of the vertical frame, and the sliding table and the vertical frame are integrally arranged in an L shape. If the arch frame is bent due to collapse, the sliding table can support the arch frame and prevent the arch frame from directly bending into the tunnel. The sliding table can form a crossbeam for temporary support, thus increasing the escape time for personnel. After the support is completed, push the vertical frame to reset. During the reset process, the first guide seat will push the bridging plate, and the bridging plate will move along the arc-shaped groove and then retract into the inner groove. The sliding table can move again, thus realizing the adjustment of the arch frame. BRIEF DESCRIPTION OF THE DRAWINGS

Through the settings of the first guide seat 11 and the second guide seat 18, they can move along the first guide groove 10 and the second guide groove 20. When the arch frame 1 moves to the topmost position, it can drive the vertical frame 3 to lap the vertical frame 3 and the arch frame 1, thus realizing the stable connection between the arch frame 1 and the vertical frame 3.
[0032] A first guide groove 10 is opened on the vertical frame 3, a second guide groove 20 is opened on the sliding table 2, the first guide groove 10 and the second guide groove 20 communicate with each other, and the shapes of the first guide groove 10 and the second guide groove 20 are the same as those of the first guide seat 11 and the second guide seat 18. Through the settings of the first guide groove 10 and the second guide groove 20, the activities between the arch frame 1 and the vertical frame 3, and the activities between the arch frame 1 and the sliding table 2 can be realized.

[0036] A first spring 14 is installed inside the arc groove 13, one end of the first spring 14 is detachably connected to the arc groove 13, and the other end of the first spring 14 is detachably connected to the guide wheel 16. The first spring 14 can realize the reset of the strap 12, and the strap 12 can be reset by the action of the first spring 14 after it is not pushed, thereby restricting the slide 2 again.
[0037] Working principle: by opening a vertical slot 4 on the frame 3, a screw rod 9 can be installed in the vertical slot 4, and the screw rod 9 can rotate in the vertical slot 4, a connecting seat 5 is installed on the screw rod 9 in the vertical slot 4, and a slide 2 is installed on one end of the connecting seat 5, and the slide 2 can move along the frame 3 following the connecting seat 5. When the arch frame 1 moves onto the slide 2, the position of the arch frame 1 can be adjusted, so that the arch frame 1 and the frame 3 can be adjusted, and the volume of the arch frame 1 and the frame 3 can be reduced for easy carrying and installation. During installation, the slide 2 is moved up, and the arch frame 1 can move to the first guide slot 10 position of the frame 3 following the slide 2, and then the frame 3 is pushed inward so that the frame 3 can be overlapped with the arch frame 1. After the arch frame 1 and the frame 3 are connected, they can be supported more stably. The arch frame 1 and the frame 3 can be quickly adjusted to complete the reinforcement of the tunnel, thereby achieving efficient reinforcement and reducing assembly time. By opening an inner groove 15 in the slide 2, a strap 12 can be installed inside the inner groove 15. When the arch frame 1 moves onto the frame 3, the strap 12 of the inner groove 15 will move to the outside of the slide 2, thereby overlapping the frame 3. At this time, the slide 2 will not move up and down, thereby achieving the fixation of the slide 2, and the slide 2 can be at the top of the frame 3. The slide 2 and the frame 3 are arranged in an L shape as a whole. If the arch frame 1 is bent due to landslide, the slide 2 can support the arch frame 1 without causing the arch frame 1 to bend directly and extend into the tunnel. The slide 2 can form a crossbeam for temporary support, thereby increasing the escape time for personnel. After the support is completed, the frame 3 is pushed to reset. During the reset process, the first guide seat 11 will push the strap 12, and the strap 12 will move along the arc groove 13, thereby retracting into the inner groove 15, and the slide 2 can move again, thereby achieving the adjustment of the arch frame 1.
