[0031] by Figure 1 Define the up, down, left, right, front, and back directions in this embodiment.

[0032] As shown in the figure, this embodiment includes a left support column 1, and a right support column 2 is located to the right of the left support column 1. Both support columns are equipped with casters 3 at their lower ends, allowing for free movement. The upper parts of the left and right support columns are connected by a lateral telescopic mechanism, which includes a left support slide 4 and a right support slide 5, the outer ends of which are fixed to the left and right support columns. The lower outer ends of the left and right support slides have groove structures, and the upper ends of the left and right support columns are respectively embedded in these groove structures and fixed with bolts. A connecting seat 6 is located above the left and right support slides. The upper parts of both left and right support slides have grooves that mate with the connecting seat 6, allowing the lower part of the connecting seat 6 to slide with the two support slides during use. An upward-facing column 7 is located at the upper end of the connecting seat 6, and its lower end is fixed to the connecting seat 6 with bolts. Stabilizing frames 8 are located on the left and right sides of the column 7, respectively. The upper and lower ends of the stabilizing frames 8 are fixedly connected to the column 7 and the connecting seat 6 with bolts, enhancing the stability of the column 7. A vertical first hydraulic cylinder 9 is installed at the upper end of the column 7, and the lower end of the cylinder body of the first hydraulic cylinder 9 is fixedly connected to the column 7. Second hydraulic cylinders 10 are installed on both the left and right sides of the connecting seat 6, and the cylinder bodies of the two second hydraulic cylinders 10 are fixedly connected to the left and right end faces of the connecting seat 6 respectively by bolts. The piston rods of the two second hydraulic cylinders 10 are fixedly connected to the left and right support slides respectively. In use, activating the second hydraulic cylinders controls the left and right support slides to move outward. In this embodiment, the side of the device closer to the column 7 in the left-right direction is defined as the inner side of this embodiment, and the side farther from the column 7 is defined as the outer side of this embodiment.

[0033] A tunnel roof support mechanism is provided above the left and right support columns. The tunnel roof support mechanism includes inner arc plates 12 arranged opposite to each other on the left and right support slides. The lower ends of each inner arc plate 12 are fixedly connected to the upper surfaces of the left and right support slides, respectively. An outer arc plate 11 is provided on the outer side of each inner arc plate 12, with a gap between each outer arc plate 11 and the inner arc plate 12. The lower ends of each outer arc plate 11 are rotatably connected to the upper ends of the left and right support slides via hinge shafts. Adjusting bolts 13 are provided between the outer arc plate 11 and the inner arc plate 12. In this embodiment, two sets of adjusting bolts 13 are provided on both the left and right sides, and the two sets of bolts are symmetrically arranged along the outer arc plate 11. The outer side of each adjusting bolt 13 is embedded in the outer arc plate 11 and fixedly connected to the outer arc plate 11 to avoid affecting the contact between the outer arc plate 11 and the tunnel body. The screw of each adjusting bolt 13 extends inward through the inner arc plate 12 and a nut is screwed on the inner side of the inner arc plate 12. The nut adopts a variable diameter nut structure, and a T-shaped groove corresponding to the position of the adjusting bolt 13 is provided on the inner side of the inner arc plate 12. The stepped surface structure of the nut matches the T-shaped groove, allowing it to slide along the T-shaped groove. In this embodiment, the smaller diameter end of the nut is hexagonal prism-shaped, extending to the inner side of the inner arc plate 12 for easy rotation of the nut. During installation, the nut is placed in the T-shaped groove and connected to the adjusting bolt 13 to support the outer arc plate 11. The outer arc plate 11 can be moved inward and outward by rotating the nut to control the opening angle of the outer arc plate 11, so that the outer arc plate 11 matches the shape of the cavity and increases the contact area with the cavity. The front and rear sides of the left and right support slides are respectively fixedly connected to the upper end of the inner arc plate 12 on the same side by reinforcing rods 15, which can enhance the support strength of the inner arc plate 12. The gap between the outer arc plate 11 and the inner arc plate 12 is a guide groove 14. An arc-shaped left support plate 16 and a right support plate 17 are respectively installed in the guide grooves 14 on the left and right sides. The left support plate 16 and the right support plate 17 can slide along the guide grooves 14 and are dynamically engaged with the outer arc plate 11 and the inner arc plate 12 on the same side, respectively. A hinge seat 18 is provided above the piston rod of the first hydraulic cylinder 9, and it is fixedly connected to the piston rod of the first hydraulic cylinder 9. The hinge seat 18 has a hinge shaft rotatably connected to it in the middle. The hinge shaft protrudes forward and backward from the hinge seat 18, and the protruding part is hinged to the upper end of the left and right support plates. Limiting grooves 20 are provided at the lower part of the left and right support plates. In this embodiment, the size and position of the limiting grooves 20 correspond to each set of adjusting bolts 13. When the left and right support plates move in the guide grooves 14, the adjusting bolts 13 can limit the movement of the left and right support plates through the limiting grooves 20. A top plate 19 is fixedly installed on the upper end of the hinge seat 18. The top plate 19 is arc-shaped. When in use, the first hydraulic cylinder 9 is activated, which can lift the top plate 19 to support the top of the tunnel.

[0034] In this embodiment, the upper outer surfaces of the left support plate 16 and the right support plate 17 are provided with stepped surfaces corresponding to the upper end surface of the outer arc plate 11. When the first and second hydraulic cylinders are retracted, the stepped surface structures of the left and right support plates come into contact with the outer arc plate 11, and the portions of the left and right support plates extending to the guide groove 14 can assist in supporting the outer arc plate 11.

[0035] An auxiliary support mechanism is provided on the outer surface of the portion of the outer arc plate 11 and the left and right support plates located outside the guide groove 14. The auxiliary support mechanism includes an auxiliary arc plate 23. In this embodiment, four auxiliary arc plates 23 are provided. Each auxiliary arc plate 23 is respectively provided on the outer surface above the upper part of the outer arc plate 11 and the step surface above the left and right support plates. A set of springs 24 is provided at the lower part of each auxiliary arc plate 23. The springs 24 are fixedly connected to the outer surface above the upper part of the outer arc plate 11 and the step surface above the left and right support plates. In use, it can increase the contact area between the device and the cavity and play an auxiliary support role.

[0036] A shim 21 is provided on the adjusting bolt 13 between the inner arc plate 12 and the outer arc plate 11. The shim 21 is cylindrical and has a mounting groove 22 with a width greater than the diameter of the adjusting bolt 13, opening from its center to its circumference. In use, the shim 21 is inserted into the adjusting bolt 13, so that the adjusting bolt 13 is located within the mounting groove 22. Adding the shim 21 improves the load-bearing strength of the outer arc plate 11. After installing the shim 21, it can be rotated so that the mounting groove 22 faces downwards, preventing the shim 21 from falling off. After the rotation angle of the outer arc plate 11 is adjusted, when the width of the guide groove 14 is small, one or two shims 21 can be used to support the outer arc plate 11; when the width of the guide groove 14 is large, a set of shims 21 needs to be installed on the same adjusting bolt 13. Shims 21 of different standard thicknesses can be designed for use during construction, ensuring that the shims 21 fill the guide groove 14 as much as possible to guarantee the support effect on the outer arc plate 11. In this embodiment, three pads 21 are mounted on the same adjusting bolt 13. The pads 21 on the inner and outer sides have a thickness adapted to the thickness of the inner arc plate 12 and the outer arc plate 11, respectively, while the pad 21 in the middle is thicker than the pads 21 on the inner and outer sides. The guide groove 14 is provided with a continuously undulating protrusion structure, and the pads 21 on the inner and outer sides are flush with each protrusion, allowing the middle pad 21 to be installed smoothly. When the left and right support plates extend into the guide groove 14, pads 21 need to be installed on the upper and lower sides of the left and right support plates respectively to press and fix the two support plates, so that the top plate part is connected to the arc plate structure on both sides, ensuring the overall support strength of the device.

[0037] Distance sensors with outward sensing direction are respectively installed above the left and right support columns. The first distance sensor 25 is fixedly installed on the front end face of the left support slide 4, and the second distance sensor 26 is fixedly installed on the front end face of the right support slide 5. The detection range is flush with the left and right end faces of the left and right support slides, and can determine whether the left and right support slides are in contact with the side of the tunnel.

[0038] In this embodiment, two left support columns 1 and two right support columns 2 are respectively arranged on the left and right sides along the front-back direction. Each left and right support column is equipped with a lateral telescopic mechanism and a tunnel roof support mechanism. Each left support column 1 and right support column 2 is equipped with a connector 27 with a socket. Each left support column 1 is fixedly connected to each other by a connecting rod 28 passing through the socket of its connector 27; each right support column 2 is fixedly connected to each other by a connecting rod 28 passing through the socket of its connector 27. This connects the left and right support columns into a whole, improving the stability of each support column.

[0039] In this embodiment, the first hydraulic cylinder 9 and the two second hydraulic cylinders 10 have the same stroke, and each hydraulic cylinder is connected to the hydraulic station 29. The three hydraulic cylinders operate synchronously through the hydraulic synchronous motor on the hydraulic station 29, avoiding uneven force distribution. Furthermore, the hydraulic station 29 is wirelessly connected to the first and second distance sensors, which can control the hydraulic station 29 to stop. The hydraulic station 29 described above uses existing technology and will not be described in detail here.

[0040] In this embodiment, during use, firstly, a set of left and right support columns with a lateral telescopic mechanism and a tunnel top support mechanism are pushed into the tunnel. After aligning the left and right support slides with the left and right sides of the tunnel, the position and curvature of the outer arc plate 11 are adjusted according to the shape of the tunnel top using adjusting bolts 13, so that the outer arc plate 11 matches the tunnel. After completion, the hydraulic station 29 is started. The first hydraulic cylinder 9 pushes the top plate 19 upward, and each of the second hydraulic cylinders 10 pushes the left and right support slides outward. The three hydraulic cylinders operate synchronously. When the first and second distance sensors detect the tunnel, they send a signal to control the hydraulic station 29 to stop. At this time, the left and right support slides contact the side of the tunnel with the top plate. Then, the casters are locked. The pad 21 is installed on the adjusting bolt 13 in the guide groove 14. After the pad 21 is installed, the next set of devices is pushed into the tunnel, and the above steps are repeated to support the tunnel. After completion, the connecting rod 28 is installed in the insertion hole of the connector 27 of each device to connect the devices to each other.
