Therefore, those skilled in the art have provided an elastic aftershock-resistant support device for tunnel lining structures to address the problems mentioned in the background art.

[0024] 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.

[0025] Please see Figures 1-5 This utility model provides a technical solution:

[0026] An elastic aftershock-resistant support device for tunnel lining structures includes:

[0027] A support frame 1 is provided, on which two support blocks 2 are fixedly mounted. A first servo cylinder 3 and two second servo cylinders 4 are mounted on each of the two support blocks 2. Two third servo cylinders 5 are mounted on both sides of the support frame 1. The output end of the first servo cylinder 3 is connected to a first connecting plate 7 through a fixing block 6. The output ends of the two second servo cylinders 4 and the two third servo cylinders 5 are all connected to a second connecting plate 8 through a connecting assembly. The connecting assembly includes a first connecting block 14 and a second connecting block 15. The first connecting block 14 is connected to the output ends of the second servo cylinders 4 and the third servo cylinders 5 respectively. The second connecting block 15 is connected to the second connecting plate 8. The first connecting block 14 and the second connecting block 15 are connected by an adjusting bolt 16.

[0028] When adjusting the movement of the top plate 9, the first servo electric cylinder 3 drives the first connecting plate 7 to move through the support block 2, which in turn drives the top plate 9 to move. The second servo electric cylinder 4 and the third servo electric cylinder 5 can drive the first connecting block 14 to move. The second moving block and the second connecting plate 8 drive the side top plate 9 to move, supporting the side of the tunnel. When the rubber layer 10 on the top plate 9 comes into contact with the tunnel, tighten the adjusting bolt 16 to fix the first connecting block 14 and the second connecting block 15, which can improve the stability of the support.

[0029] The first connecting plate 7 and the second connecting plate 8 are both connected to the top plate 9 through a buffer assembly. The buffer assembly includes a buffer spring 17, a buffer element 18, and a damper 19. One side of the buffer element 18 is connected to the first connecting plate 7 or the second connecting plate 8, and the other side of the buffer element 18 is connected to the top plate 9. The buffer spring 17 is sleeved on the outside of the damper 19. One end of the buffer spring 17 and the damper 19 is connected to the first connecting plate 7 or the second connecting plate 8, and the other end of the buffer spring 17 and the damper 19 is connected to the top plate 9. A rubber layer 10 is provided on the top plate 9. The rubber layer 10 can provide elastic support. When an earthquake occurs, the rubber layer 10 can absorb and disperse earthquake energy, reducing the vibration and deformation of the tunnel structure.

[0030] When the tunnel vibrates, the roof slab 9 compresses the buffer spring 17, the buffer element 18 and the damper 19. When the tunnel is subjected to external pressure, the buffer spring 17 will undergo elastic deformation, thereby absorbing some energy. The damper 19 can significantly improve the seismic performance of the tunnel and reduce the degree of damage to the tunnel structure caused by earthquakes.

[0031] The buffer 18 is an elliptical spring sheet. When subjected to external force, the elliptical spring sheet can undergo elastic deformation, thereby absorbing and storing vibration energy.

[0032] Furthermore, the support frame 1 has several through holes 12 and several reinforcing rods 13 are installed on the support frame 1.

[0033] Several through holes 12 can reduce stress concentration in the support frame 1, and several reinforcing rods 13 can strengthen the support strength of the support frame 1.

[0034] A pulley 11 is installed at the lower end of the support frame 1. The pulley 11 is slidably connected to the track 20. Mounting blocks 21 are provided at both ends of the track 20. Mounting thread holes 22 are provided on the mounting blocks 21.

[0035] When the support frame 1 moves, the pulley 11 can move on the track 20. When the track 20 is fixed, bolts are used to connect with the mounting threaded holes 22 to fix the mounting block 21.

[0036] The support frame 1 is equipped with a fixing mechanism on both sides. The fixing mechanism includes a fixing plate 23, two spiral cones 24, a servo motor 25, two rotating parts 26 and a connecting part 27. The fixing plate 23 is fixedly installed on the support frame 1. The servo motor 25 is installed on the support frame 1 and the output end of the servo motor 25 is connected to the connecting part 27. The two rotating parts 26 are connected to the fixing plate 23 through a limiting component. The connecting part 27 is connected to the two rotating parts 26 through a transmission belt 28. The two spiral cones 24 are threadedly connected to the two rotating parts 26 and the two spiral cones 24 are threadedly connected to the fixing plate 23.

[0037] When the support frame is fixed, the servo motor 25 drives the connector 27 to rotate. The connector 27 drives the two rotating parts 26 to rotate through the transmission belt 28. Since the rotating parts 26 are threadedly connected to the spiral cone 24 and the spiral cone is threadedly connected to the fixed plate 23, the spiral cone 24 can be driven to rotate, causing the spiral cone 24 to move down and embed itself into the ground, thus fixing the support frame 1.

[0038] The limiting component includes a limiting ring 29, which is connected to two rotating parts 26. The fixed plate 23 has a limiting groove 30 for the limiting ring 29 to rotate and connect.

[0039] When the rotating part 26 rotates, the limiting ring 29 rotates within the limiting groove 30, which can limit the rotation of the rotating part 26.

[0040] 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.
