Abstract
Description
Technical Field
[0001] This invention relates to the field of tunnel inspection equipment technology, specifically to an intelligent inspection device for the arch of a railway tunnel. Background Technology
[0002] With societal development, tunneling for railway construction has become a means to improve transportation convenience. However, tunnel walls may harbor cracks, holes, fissures, and water seepage, directly impacting tunnel lifespan and traffic safety. Therefore, inspecting railway tunnels is a crucial measure to ensure traffic safety. Currently, the mainstream tunnel inspection technology utilizes vehicle-mounted ground-penetrating radar (GPR). After the GPR extends to the target location, a moving vehicle actuates it to conduct the detection. However, current common inspection equipment can only inspect flat-roofed tunnels, not domed ones.
[0003] Chinese patent CN218494566U discloses a railway tunnel arch detection device. This device allows the radar detector to move laterally and deflect, enabling it to detect both flat-topped and domed tunnels. A second electric telescopic rod can also extend, raising the fixed box to accommodate tunnels of different heights and shapes. However, during use, the presence of lighting devices, electrical grids, and supporting beams at the tunnel ceiling means that if the radar detector remains at the same height throughout the device's movement, it will collide with these structures. Frequent height adjustments via the second electric telescopic rod are cumbersome and make it difficult for users to observe the radar detector's height, leading to inconsistencies in the detection results. Summary of the Invention

[0048] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.
[0049] See Figure 1 , Figure 4 and Figure 10As shown, an intelligent detection device for the arch of a railway tunnel includes a movable base 1, a lifting component 2, an angle adjustment component 3, a detection component 4, and a control component 5. The control component 5 includes a control handle 51, a first control shaft 52, and a second control shaft 53. A lighting structure is fixedly installed at one end of the movable base 1. The angle adjustment component 3 is fixedly installed on the output end of the lifting component 2 near the lighting structure. The detection component 4 is fixedly installed on the output end of the angle adjustment component 3. The control handle 51 is installed on the output end of the lifting component 2 away from the lighting structure. The first control shaft 52 is rotatably mounted on the control handle 51. A torsion spring 521 is installed between the first control shaft 52 and the control handle 51. When the first control shaft 52 rotates, it works with the angle adjustment component 3 to adjust the vertical direction of the detection component 4. The second control shaft 53 is rotatably mounted on the control handle 51. A fixing structure is installed between the second control shaft 53 and the control handle 51 to fix the second control shaft 53. The second control shaft 53 is coaxial with the first control shaft 52. When the second control shaft 53 rotates, it works with the angle adjustment component 3 to adjust the detection angle of the detection component 4.
[0050] Activating the lifting assembly 2 causes its output end to move vertically. The output end of the lifting assembly 2 drives the angle adjustment assembly 3 and control assembly 5 to move vertically to a suitable height for the tunnel being inspected. Then, the moving base 1 is moved by the control handle 51. When an obstacle appears in the path of the detection assembly 4, the first control shaft 52 is rotated. This rotation causes the detection assembly 4 to move vertically downwards to avoid the obstacle. After the detection assembly 4 passes the obstacle, the first control shaft 52 is released. Under the action of the torsion spring 521, the first control shaft 52 rotates in the opposite direction, causing the detection assembly 4 to move vertically upwards. When an angle adjustment is needed... During height adjustment, the second control shaft 53 is rotated to deflect the detection component 4. Then, the detection direction of the detection component 4 is fixed by a fixing structure. Compared with the prior art, the first rotating shaft of the present invention, together with the angle adjustment component 3, allows the detection component 4 to move down in the vertical direction conveniently and quickly. The second rotating shaft and the angle adjustment component 3 allow the detection component 4 to change the detection angle conveniently and quickly. This allows the detection component 4 to frequently perform small-distance height adjustments, thereby ensuring that the detection component 4 will not collide with obstacles such as lighting devices, power grids, and support beams on the tunnel top when moving along the tunnel length, thus affecting the overall detection work.
[0051] See Figure 1 , Figures 4-5 and Figure 9As shown: The angle adjustment component 3 includes a fixed cylinder 31, a first movable block 32, and a first tension spring 33. The fixed cylinder 31 is rotatably mounted on the output end of the lifting component 2. The rotation axis of the fixed cylinder 31 is parallel to the line connecting the lighting structure and the control component 5. The first movable block 32 is slidably mounted inside the fixed cylinder 31. The sliding line of the first movable block 32 is parallel to the length direction of the fixed cylinder 31. An extension rod is provided on the first movable block 32, extending away from the lifting component 2. The extension rod extends to the outside of the fixed cylinder 31 and is fixedly connected to the detection component 4. One end of the first tension spring 33 is fixedly mounted above the first movable block 32, and the other end of the first tension spring 33 is fixedly connected to the fixed cylinder 31. The first tension spring 33 is sleeved on the extension rod. When the first control shaft 52 rotates, it can drive the first movable block 32 to move.
[0052] When it is necessary to control the vertical adjustment of the detection component 4, the first control shaft 52 is rotated. When the first control shaft 52 rotates, it will drive the first movable block 32 to move downward along the length of the fixed cylinder 31. The first tension spring 33 is stretched, so that the detection component 4 moves downward accordingly. When the detection component 4 passes through obstacles such as lighting devices, electric grids, and support beams, the first control shaft 52 is released, and the first tension spring 33 is released from its stretched state, so that the detection component 4 moves back to the initial position. Compared with the prior art, the first tension spring 33 of the present invention can ensure that the first movable block 32 is at a high position without external force, so that the detection component 4 can automatically return to the detection height after passing through obstacles such as lighting devices, electric grids, and support beams.
[0053] See Figure 1 , Figures 4-5 and Figure 9 As shown: The angle adjustment component 3 also includes a second movable block 34 and a hinge rod 35. The second movable block 34 is slidably disposed on the output end of the lifting component 2. There are two second movable blocks 34, which are mirror images of each other at both ends of the fixed cylinder 31. The sliding direction of the second movable block 34 is perpendicular to the moving direction of the output end of the lifting component 2 and perpendicular to the rotation axis of the fixed cylinder 31. One end of the hinge rod 35 is hinged to the second movable block 34, and the other end of the hinge rod 35 is hinged to the outer wall of the fixed cylinder 31. The second control shaft 53 can rotate to drive the second movable block 34 to move.
[0054] When it is necessary to adjust the detection angle of the detection component 4, the second control shaft 53 is rotated, and the second movable block 34 will move along with the rotation of the second control shaft 53. The second movable block 34 and the hinge rod 35 cooperate to make the fixed cylinder 31 drive the detection component 4 to rotate. Compared with the prior art, the second movable block 34, the hinge rod 35 and the second control shaft 53 of the present invention cooperate to make the fixed cylinder 31 rotate, thereby enabling the detection component 4 to change the detection angle.
[0055] See Figure 1 , Figure 4 , Figures 6-8 and Figures 10-11 As shown: The control component 5 also includes a first rotating shaft 54 and a pull rope 55. The first rotating shaft 54 is rotatably disposed in the control handle 51. One end of the pull rope 55 is fixedly connected to the side wall of the first rotating shaft 54. The other end of the pull rope 55 is fixedly connected to the first movable block 32. A first control gear 522 is coaxially fixedly disposed at the end of the first control shaft 52. A first connecting gear 541 is coaxially fixedly disposed at the end of the first rotating shaft 54. The first control gear 522 and the first connecting gear 541 are connected by a first transmission belt 542.
[0056] When the first control shaft 52 rotates, it will cause the first rotating shaft 54 to rotate through the cooperation of the first control gear 522, the first connecting gear 541 and the first transmission belt 542. When the first rotating shaft 54 rotates, it will drive the pull rope 55 to continuously retract onto the first rotating shaft 54, thereby causing the first movable block 32 to move. Compared with the prior art, the cooperation of the first rotating shaft 54 and the pull rope 55 in this invention allows the first movable block 32 to move by following the rotation of the first control shaft 52, thereby enabling the first control shaft 52 to drive the first movable block 32 to move.
[0057] See Figure 1 , Figure 4 , Figures 6-8 and Figures 10-11 As shown: Control component 5 also includes gear shaft 56 and third movable block 57. Gear shaft 56 is rotatably disposed in the output end of lifting component 2. The axis of gear shaft 56 is parallel to the moving direction of second movable block 34. A threaded rod is provided on gear shaft 56. Third movable block 57 is threadedly connected to gear shaft 56. A first fixed protrusion 571 that can drive second movable block 34 to move is fixedly provided on third movable block 57. A first fixed hole 341 that matches the first fixed protrusion 571 is provided on second movable block 34. A second connecting gear 543 is coaxially rotatably disposed at the end of first rotating shaft 54. A second control gear is coaxially fixedly disposed at the end of second control shaft 53. Second control gear and second connecting gear 543 are connected by second transmission belt 544. Second connecting gear 543 and gear shaft 56 are connected by third transmission belt 545.
[0058] When the second control shaft 53 rotates, it cooperates with the second control gear, the second connecting gear 543, the gear shaft 56, the second transmission belt 544, and the third transmission belt 545 to enable the gear shaft 56 to rotate in tandem with the second control shaft 53. When the gear shaft 56 rotates, it causes the third movable block 57 to move along the axial direction of the gear shaft 56. The third movable block 57 cooperates with the first fixed protrusion 571 and the first fixed hole 341 to enable the second movable block 34 to move in tandem with the second control shaft 53. Compared with the prior art, the gear shaft 56, the third movable block 57, and the second control shaft 53 of the present invention cooperate to enable the second movable block 34 to move in tandem with the rotation of the second control shaft 53, thereby enabling the second control shaft 53 to drive the second movable block 34 to move.
[0059] See Figure 1 , Figure 4 , Figures 6-8 and Figures 10-11 As shown: the control handle 51 is U-shaped. One end of the control handle 51 is fixedly provided with a fixed sleeve 511 coaxial with the second control shaft 53. The other end of the control handle 51 is fixedly provided with a second rotating shaft 512 parallel to the axis of the second control shaft 53. There are two control handles 51, which are arranged in a mirror image. The second rotating shafts 512 of the two control handles 51 are arranged opposite to each other. The first control shaft 52 is located between the two control handles 51.
[0060] When the second control shaft 53 is not required to rotate, the movable base 1 is moved by holding the two fixed sleeves 511. When the angle and height of the detection component 4 need to be adjusted, one hand holds one fixed sleeve 511 and the other hand controls the first control shaft 52 or the second control shaft 53 to rotate. Compared with the prior art, the control handle 51 of the present invention has a defined shape, so that the control handle 51 can be used by the user in a convenient way.
[0061] See Figure 1 , Figure 4 , Figures 6-8 and Figures 10-11 As shown: The fixing assembly includes a rotating wheel 531, which is slidably connected to the second control shaft 53 on the same axis. The sliding direction of the rotating wheel 531 is parallel to the axis of the second control shaft 53. The rotating wheel 531 can drive the second control shaft 53 to rotate. The rotating wheel 531 is located outside the fixing rod. A second fixing protrusion 532 is fixedly provided on the side of the rotating wheel 531 near the fixing rod. A second fixing hole 513 that matches the second fixing protrusion 532 is provided on the fixing sleeve 511. There is at least one second fixing hole 513. All the second fixing holes 513 are evenly arranged around the axis of the fixing rod. There is one rotating wheel 531.
[0062] When the angle of the detection component 4 needs to be adjusted, the control wheel 531 moves away from the fixed sleeve 511. Then, the wheel 531 drives the second control shaft 53 to rotate. When the second control shaft 53 rotates, it drives the second movable block 34 to move. After the detection angle of the detection component 4 is adjusted, the control wheel 531 moves closer to the fixed sleeve 511 again. Then, the second fixing protrusion 532 is inserted into the second fixing hole 513 to fix the state of the second control shaft 53. Compared with the prior art, the wheel 531, the second fixing protrusion 532 and the second fixing hole 513 of the present invention cooperate to fix the state of the second control shaft 53, thereby ensuring that the detection angle of the detection component 4 will not change arbitrarily.
[0063] See Figure 1 , Figure 4 , Figures 6-8 and Figures 10-11 As shown: The fixing assembly also includes a second tension spring 533, which is fixedly disposed between the second control shaft 53 and the rotating wheel 531, and the axis of the second tension spring 533 is coaxial with the axis of the second control shaft 53.
[0064] When the control wheel 531 moves away from the fixed sleeve 511, the second tension spring 533 will be stretched. Then, the wheel 531 drives the second control shaft 53 to rotate. When the second sliding block moves to the appropriate position with the rotation of the second control shaft 53, the wheel 531 is released, the second tension spring 533 is released, and the wheel 531 will automatically move closer to the fixed sleeve 511, so that the second fixing protrusion 532 is inserted into the second fixing hole 513. Compared with the prior art, the second tension spring 533 of the present invention ensures that the wheel 531 can automatically move closer to the fixed sleeve 511, so that the second control shaft 53 can be fixed in position when the wheel 531 is not in use.
[0065] See Figure 1 , Figure 4 , Figures 6-8 and Figures 10-11 As shown: The second rotating shaft 512 is rotatably connected to the output end of the lifting component 2, and the second rotating shaft 512 is a fastener.
[0066] When the output end of the lifting component 2 moves to different heights, the second rotating shaft 512 is controlled to rotate. Since the second rotating shaft 512 is a fastener, the second rotating shaft 512 provides support force after the position of the control handle 51 is adjusted, so that the position of the control handle 51 is fixed. Compared with the prior art, the second rotating shaft 512 of the present invention allows the angle of the control handle 51 to be adjusted, thereby facilitating use by users of different heights.
[0067] See Figure 1 , Figure 4 , Figures 6-8 and Figures 10-11 As shown: The control component 5 also includes a third tension spring 58, which is sleeved on the gear shaft 56. One end of the third tension spring 58 is fixedly connected to the output end of the lifting component 2, and the other end of the third tension spring 58 is fixedly connected to the third movable block 57.
[0068] When no adjustment is required, the movable wheel 531 causes the second fixed protrusion 532 to move the second fixed hole 513. At this time, the third tension spring 58 provides elastic force, causing the two third movable blocks 57 to drive the second movable block 34 to move to the initial position, thereby making the detection component 4 in the vertical direction. Compared with the prior art, the third tension spring 58 of the present invention enables the third movable block 57 to move to the initial position, thereby facilitating storage and folding when the device is not in use.
[0069] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
