[0038] To facilitate understanding by those skilled in the art, the present invention will be further described below in conjunction with embodiments and accompanying drawings. Specific embodiments of the present invention will be described below. It should be noted that, in order to provide a concise description of these embodiments, this specification cannot provide a detailed description of all features of the actual embodiments.

[0039] refer to Figures 1 to 8 As shown, this utility model provides a tunnel lining support device, including an arc-shaped base frame 1, an arc-shaped guide groove 101 disposed on the base frame 1, a connector 2 slidably connected to the arc-shaped guide groove 101, a driving mechanism 3 for driving the connector 2 to move along the arc-shaped guide groove 101, and a support member 4 connected to the connector 2. The support member 4 is provided with a support part 401, which is used to abut against the inner wall of the tunnel.

[0040] refer to Figure 1 , 2 As shown, in practical applications, the drive mechanism 3 drives the connecting piece 2 to move, thereby changing the position of the support piece 4 on the base frame 1, so that the support part 401 can support the tunnel inner wall at different positions, which is convenient to flexibly adapt to the changing construction conditions, improve the applicability of the device, and help to speed up the construction progress.

[0041] refer to Figure 2 As shown, in this embodiment, the connector 2 includes a connecting seat 21 slidably connected to the arc-shaped guide groove 101 and a connecting rod 22 rotatably connected to the connecting seat 21. The connecting rod 22 is driven to connect to the driving mechanism 3, and the connecting rod 22 is rotatably connected to the arc-shaped guide groove 101. The driving mechanism 3 drives the connecting rod 22 to rotate, and causes the connecting rod 22 and the connecting seat 21 to move synchronously along the arc-shaped guide groove 101, guiding the connecting rod 22 and the connecting seat 21 to move smoothly within the arc-shaped guide groove 101, facilitating the smooth movement of the connector 2 and improving structural stability.

[0042] refer to Figure 3 As shown, in this embodiment, the support member 4 includes a support sleeve 41 and a support rod 42 connected to the support sleeve 41. The support sleeve 41 is sleeved on the connecting rod 22, the support part 401 is disposed on the support rod 42, the base frame 1 is provided with a sliding groove 102, and the support rod 42 is provided with a sliding rod 421, which is slidably engaged with the sliding groove 102.

[0043] In practical applications, the drive mechanism 3 drives the connecting rod 22 to move along the arc-shaped guide groove 101, and drives the slide rod 421 to slide in the slide groove 102, so that the support rod 42 moves along the extension direction of the arc-shaped guide groove 101, which facilitates the guidance of the support rod 42 and makes it easier to move the support rod 42 smoothly.

[0044] refer to Figure 4 As shown, in this embodiment, the driving mechanism 3 includes a driving unit 31 whose output end is drivenly connected to the connecting rod 22, a gear 32 connected to the connecting rod 22, and a gear ring 33 installed on the inner side wall of the arc-shaped guide groove 101. The gear 32 meshes with the gear ring 33, and the driving unit 31 slides in the arc-shaped guide groove 101.

[0045] In practical applications, the drive unit 31 uses a servo motor or drive motor. Since the drive unit 31 slides in the arc-shaped guide groove 101, the swing of the drive unit 31 is effectively restricted, so that the drive unit 31 can only slide along the arc-shaped guide groove 101, ensuring the stable sliding of the drive unit 31. The drive unit 31 drives the connecting rod 22 to rotate. Under the action of the gear 32 and the gear ring 33, the drive unit 31 and the connecting rod 22 move along the extension direction of the arc-shaped guide groove 101, smoothly driving the connecting piece 2 to move along the extension direction of the arc-shaped guide groove 101, thereby adjusting the position of the support part 401.

[0046] refer to Figure 5 As shown, in this embodiment, the two ends of the arc-shaped guide groove 101 are through, and the connecting seat 21 and the driving unit 31 respectively extend out of the two ends of the arc-shaped guide groove 101. The connecting seat 21 is provided with a connecting ear plate 211, which fits against one side of the base frame 1. The driving unit 31 is provided with a driving ear plate 311, which fits against the other side of the base frame 1. In actual application, the movement of the driving unit 31, the connecting rod 22 and the connecting seat 21 in the axial direction of the connecting rod 22 is restricted to prevent axial relative sliding between the gear 32 and the gear ring 33, reduce scratches between the gear 32 and the gear ring 33, and ensure stable transmission between the gear 32 and the gear ring 33, thus ensuring transmission accuracy.

[0047] refer to Figure 6 As shown, in this embodiment, the base frame 1 is provided with a storage cavity 103. The storage cavity 103 penetrates the outside of the base frame 1 and communicates with the arc-shaped guide groove 101 and the sliding groove 102. The sliding groove 102 is symmetrically distributed on both sides of the storage cavity 103. At least two sliding rods 421 are provided and slide in cooperation with the sliding grooves 102 on both sides respectively. The support rod 42 passes through the storage cavity 103. The sliding rods 421 provide stable support for the support rod 42, improving the structural stability of the support rod 42. The support rod 42 is hidden inside the base frame 1, saving space and making the structure compact.

[0048] refer to Figure 6 As shown, in this embodiment, the bottom end of the arc-shaped guide groove 101 has an observation port 1011, which is located below the support member 4. An observation plate 1012 made of transparent material is installed inside the observation port 1011. In actual application, the observation plate 1012 is made of transparent acrylic sheet, which effectively prevents dust or residue from falling down along the arc-shaped guide groove 101, which is convenient for protecting the safety of the user when working on the inside of the base frame 1. It also makes it convenient for the user to observe the working condition between the tunnel inner wall and the support device through the observation plate 1012, which is conducive to timely feedback of the construction progress.

[0049] refer to Figure 7As shown, in this embodiment, the arc-shaped guide groove 101 is provided with a plurality of connectors 2, and the two opposite ends of the support part 401 are respectively provided with splicing blocks 4011 and splicing grooves 4012. When two adjacent support parts 4 approach each other, the two adjacent support parts 401 are spliced ​​together by the splicing blocks 4011 and splicing grooves 4012. The adjacent support parts 401 can overlap each other in the support area. When part of the support part 401 is folded, the remaining support part has a larger space for movement, expanding the range of movement of the support part 401. In practical applications, each connector 2 is driven by a corresponding drive mechanism 3, which makes it easy to adjust the position of the support part 4. The support part 4 can skip over areas in the tunnel wall that are easy to crack or have poor wall support, which are not convenient for support, ensuring construction safety and having a wide range of applications.

[0050] refer to Figure 8 As shown, in this embodiment, the support rod 42 includes a support base 4201 and a linear module 4202 connected to the support base 4201. The support base 4201 is connected to the support sleeve 41, and the slide rod 421 is connected to the support base 4201. The output end of the linear module 4202 is connected to the support part 401. The linear module 4202 drives the support part 401 to move, so that the support part 401 moves closer to or further away from the support sleeve 41.

[0051] In practical applications, the linear module 4202 uses a pneumatic cylinder, electric cylinder, or hydraulic cylinder. The support base 4201 provides stable support for the linear module 4202. The linear module 4202 drives the support part 401 to move towards the inner wall of the tunnel, which makes it easy to control the movement distance of the support part 401. It can adapt to tunnels of different sizes and broaden the applicability range of this support device.
