Furthermore, in the description of this invention, terms such as "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0028] This embodiment provides an adjustable support for fixing monitoring sensors in tunnels, such as... Figure 1 , Figure 2 and Figure 3 As shown, it includes: a fixed plate 5, a rotating plate 4, a first telescopic rod, an adjusting device, a second telescopic rod, and a vertical rod 14.

[0029] The fixing plate 5 is provided with multiple bolt holes 13, and the fixing plate 5 is connected to the tunnel wall through the bolt holes 13 and expansion bolts.

[0030] The rotating plate 4 is rotatably connected to the first side of the fixed plate 5. An angle measuring device 6 is provided at the connection between the rotating plate 4 and the fixed plate 5 for measuring the angle between the rotating plate 4 and the fixed plate 5. The angle measuring device 6 can be a protractor, angle ruler, angle meter, or other device or instrument for measuring angles, and is not specifically limited in this application.

[0031] The lower surface of the rotating plate 4 is provided with a first sliding groove 22, which is perpendicular to the first side. The lower surface of the rotating plate 4 is the surface facing the fixed plate 5. Adjustment grooves 16 are provided on both sides of the first sliding groove 22, and the adjustment grooves 16 penetrate the upper and lower surfaces of the rotating plate 4.

[0032] The upper surface of the fixing plate 5 is provided with a first mounting groove 8, which is perpendicular to the first side and the second side. The shape and position of the first mounting groove 8 correspond to the shape and position of the first telescopic rod. The upper surface of the fixing plate 5 is the surface of the fixing plate 5 facing the rotating plate 4. The upper surface of the fixing plate 5 and the lower surface of the rotating plate 4 are both provided with a second mounting groove 15, the shape and position of which correspond to the shape and position of the fixing rod 18.

[0033] It is understood that when the angle between the fixed plate 5 and the rotating plate 4 is 0, that is, when the upper surface of the fixed plate 5 coincides with the lower surface of the rotating plate 4 and the present application is in a folded state, the first slide groove 22 and the first mounting groove 8 are used to place the first telescopic rod, and the second mounting groove 15 is used to place the fixing rod 18.

[0034] One end of the first telescopic rod is rotatably connected to the middle of the second side of the fixed plate 5, and the other end of the first telescopic rod can be slidably connected in the first slide groove 22. The first side and the second side are opposite sides and parallel to each other.

[0035] The specific structure of the first telescopic rod is as follows: Figure 4 As shown, the first telescopic rod includes a first sleeve 3, a first inner rod 21, and a fixing rod 18. A horizontal fixing rod 18 is fixedly connected to the top of the first sleeve 3, and the bottom of the first sleeve 3 is rotatably connected to the middle of the second side of the fixing plate 5. A compression spring 23 is provided at the bottom inner side of the first sleeve 3. The first sleeve 3 has a hollow structure and an open top surface. The lower end of the first inner rod 21 is inserted into the first sleeve 3 through the opening on the top surface of the first sleeve 3, and wheelsets 20 are provided on both sides of its upper end. The top of the first inner rod 21 can slide in the first sliding groove 22. Studs are provided at both ends of the fixing rod 18.

[0036] like Figure 5 As shown, second slide grooves 24 are symmetrically arranged on both sides of the first slide groove 22. The second slide grooves 24 are parallel to the first slide groove 22, and the wheelset 20 can slide in the second slide grooves 24. The two ends of the second slide grooves 24 are arc-shaped to hold the wheelset 20. When the fixed plate 5 and the rotating plate 4 open and close, the compression spring 23 generates a thrust on the first inner rod 21, causing the first inner rod 21 to slide inside the first sleeve 3 and the wheelset 20 to slide in the second slide grooves 24.

[0037] It should be noted that when the top of the first inner rod 21 is at the front end of the first slide groove 22 and the wheel set 20 is stuck at the front end of the second slide groove 24, the angle between the fixed plate 5 and the rotating plate 4 can be adjusted by adjusting the length of the first inner rod 21 extending out of the first sleeve 3. When the required angle is almost reached, the tightening bolt 10 in the middle of the fixing rod 18 is tightened. The tightening bolt 10 applies pressure to the first inner rod 21, so that the length of the first inner rod 21 extending out of the first sleeve 3 is fixed, thereby fixing the angle between the fixed plate 5 and the rotating plate 4.

[0038] One end of the adjustment device is connected to the first telescopic rod, and the other end passes through the adjustment groove 16 and is connected to the upper surface of the rotating plate 4. The upper surface of the rotating plate 4 is the side of the rotating plate 4 that faces away from the fixed plate 5.

[0039] Specifically, there are two adjustment devices, symmetrically arranged on both sides of the first telescopic rod, each including an adjustment rod 1, a first adjustment nut 2, a second adjustment nut 7, and a rotating sleeve 19; the adjustment rod 1 is a rod-shaped structure with external threads, the lower end of which passes through the rotating sleeve 19 and connects to the first adjustment nut 2, and the upper end passes through the adjustment groove 16 and connects to the second adjustment nut 7, the diameter of the second adjustment nut 7 being larger than the width of the adjustment groove 16; the rotating sleeve 19 has internal threads on the side facing the first telescopic rod, and the rotating sleeve 19 is connected to the studs at both ends of the fixed rod 18 through the internal threads.

[0040] It should be noted that the adjustment device is detachable. The installation process is as follows: After the angle between the fixed plate 5 and the rotating plate 4 is fixed, rotating sleeves 19 are screwed onto the studs at both ends of the fixed rod 18. The adjusting rod 1 passes through the rotating sleeve 19 and the adjusting groove 16. A first adjusting nut 2 is installed on the adjusting rod 1 from its lower end, with the upper surface of the first adjusting nut 2 tightly against the lower surface of the rotating sleeve 19. The tightening bolt 10 in the middle of the fixed rod 18 is slightly loosened, allowing the upper end of the adjusting rod 1 to move within the adjusting groove 16. As the adjusting rod 1 rotates, the rotating sleeve 19 rotates along with it, ensuring that the upper surface of the rotating sleeve 19 remains parallel to the rotating plate 4. This allows for fine-tuning of the angle between the fixed plate 5 and the rotating plate 4. After fine-tuning to the desired angle, the tightening bolt 10 in the middle of the fixed rod 18 is tightened again. A second adjusting nut 7 is installed from the upper end of the adjusting rod 1, with the lower surface of the second adjusting nut 7 tightly against the upper surface of the rotating plate 4. The first telescopic rod works in conjunction with the adjustment device to achieve the angle adjustment described in this application.

[0041] The second telescopic rod is connected to the upper surface of the rotating plate 4. The second telescopic rod includes a second sleeve 9, a second inner rod 11, and a bracket 12; the second sleeve 9 is a hollow structure with an open top surface. The lower end of the second inner rod 11 is located inside the first sleeve 3 through the opening on the top surface of the second sleeve 9, allowing it to slide inside the second sleeve 9. The top end of the second inner rod 11 is connected to a vertical rod 14. One end of the bracket 12 is connected to the top of the second sleeve 9, and the other end is connected to the upper surface of the rotating plate 4. One or more brackets 12 are provided. The bracket 12 and the second sleeve 9 form a triangular structure for stable installation of the second sleeve 9.

[0042] It is understandable that the length of this application can be adjusted by adjusting the length of the second inner rod 11 extending out of the second sleeve 9 and then tightening the tightening bolt 10 at the upper end of the second sleeve 9.

[0043] The vertical rod 14 is vertically connected to the top of the second telescopic rod. The vertical rod 14 is connected to the second telescopic rod through a mounting base 17. The mounting base 17 has a through hole inside, in which the vertical rod 14 can slide. The mounting base 17 has a tightening bolt 10 inside, perpendicular to the through hole.

[0044] The installation diagram of this application and the tunnel wall is shown below. Figure 6 As shown, the vertical rod 14 is perpendicular to the horizontal plane, and the monitoring sensor is mounted on the vertical rod 14 for measurement. By adjusting the position of the vertical rod 14 in the through hole, the monitoring sensor can be adjusted to a small distance in the vertical direction.

[0045] Compared with existing integrated welded fixed supports, this application not only achieves the functions of an integrated welded fixed support, but also requires minimal preparation during installation, manufacturing, and use. Furthermore, its foldable feature makes it portable, suitable for tunnel walls at different angles, and has wide applicability. In addition, this application can reduce installation errors through various adjustment methods, making it suitable for various tunnel monitoring scenarios.

[0046] The above description is merely a preferred embodiment of the present invention and is not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.

[0047] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
