[0028] Traditional segment brackets are usually only suitable for a single type of segment. When the size and shape of the segment changes, the bracket is not tightly fitted to the segment, the bracket's support stability is insufficient, and the segment is prone to displacement or tilt during inspection, affecting the inspection results and even potentially causing safety accidents.

[0029] The present invention proposes a bracket for a tunnel segment 60, which is used to support the segment 60. A splicing groove 61 is opened on the side of the segment 60. The bracket for the tunnel segment 60 proposed by the present invention includes a base plate 10, a rotating support 20, a telescopic support 30 and a side support 40. A hinge seat 11 is provided on the base plate 10; the rotating support 20 is tilted relative to the base plate 10, the bottom of the rotating support 20 is hinged to the hinge seat 11, and the top of the rotating support 20 is supported on the bottom surface of the segment 60; the telescopic support 30 is provided on the base plate 10 and can be telescopic in the vertical direction, the top of the telescopic support 30 is supported on the bottom surface of the segment 60, and the telescopic support 30 is spaced apart from the rotating support 20; the side support 40 is vertically provided, the bottom of the side support 40 is connected to the base plate 10, and the top of the side support 40 is provided with a rolling assembly 41. The rolling assembly 41 includes a rolling block 411. The rolling block 411 extends into the splicing groove 61 and rolls with the splicing groove 61.

[0030] See also Figure 1 and Figure 2 , Figure 1 and Figure 2 The vertical direction is defined as the vertical direction. The rotating support 20 and the telescopic support 30 are spaced apart on the base plate 10 and jointly support the bottom surface of the segment 60, which has a curved surface. The side supports 40 are disposed on the base plate 10 and support the sides of the segment 60. The bracket, through the rotating support 20, the telescopic support 30, and the side supports 40, provides stable support for the segment 60. The rotating support 20 is hinged to the hinge seat 11, allowing it to rotate relative to the base plate 10. This allows the rotating support 20 to adjust its support angle for the segment 60 according to the curvature of the segment 60, ensuring that the rotating support 20 always supports the bottom surface of the segment 60 perpendicularly, thereby ensuring that the top of the rotating support 20 is in close contact with the bottom surface of the segment 60. The telescopic support 30 extends vertically and can be retracted vertically, allowing the telescopic support 30 to adjust its length according to the curvature of the segment 60, ensuring that the top of the vertical support is in close contact with the bottom surface of the segment 60. Splicing grooves 61 are formed on the sides of the segments 60 to connect and secure the segments 60 to each other. The side supports 40 extend into the splicing grooves 61 via rolling blocks 411 to provide lateral support to the segments 60 and prevent lateral displacement. Since the joints of segments 60 of different shapes and sizes are located at different positions, the rolling blocks 411 can roll along the splicing grooves 61, allowing the side supports 40 to roll and fit at different positions on the segments 60, ensuring that the side supports 40 can provide lateral support for segments 60 of varying sizes and curvatures.

[0031] The bracket of the tunnel segment 60 proposed by the present invention provides support for the segment 60 by arranging rotating supports 20, telescopic supports 30 and side supports 40 at intervals on the base plate 10. The rotating supports 20 can adjust their own support angles according to the different curvatures of the bottom surface of the segment 60, thereby ensuring that they are always in close contact with the bottom surface of the segment 60; after the rotating support 20 is adjusted and fixed, the top of the telescopic support 30 is made to fit closely with the bottom surface of the segment 60 by adjusting the length of the telescopic support 30, so that the weight of the segment 60 is distributed through the telescopic support 30; the side supports 40 slide with the splicing groove 61 on the side of the segment 60 through the rolling blocks 411, so that the side supports 40 can provide lateral support for segments 60 of different sizes and curvatures, and prevent the segment 60 from undergoing lateral displacement. Through the flexible setting of the rotating support 20, the telescopic support 30 and the side support 40, the bracket can adapt to pipe segments 60 of different shapes and sizes, effectively improving the adaptability of the bracket; the bracket can provide stable support when supporting pipe segments 60 of different shapes and sizes, and the support stability is good, ensuring that the pipe segment 60 remains stable during the detection process, thereby improving the safety of the detection process and ensuring that the detection results are more accurate.

[0032] In one embodiment, the rolling assembly 41 also includes a first connecting plate 412 and a second connecting plate 413, the rolling block 411 can be rotatably connected to the first connecting plate 412, the top of the side support 40 is fixedly connected to the second connecting plate 413, the first connecting plate 412 and the second connecting plate 413 can be detachably connected, and the first connecting plate 412 can be connected to any height position of the second connecting plate 413.

[0033] See also Figure 3 The rolling block 411 is rotatably connected to the first connecting plate 412. When the rolling block 411 rolls to different positions along the splicing groove 61, the first connecting plate 412 moves with the rolling block 411. The side supports 40 and the second connecting plate 413 are fixed in position. When installing the side supports 40, the first connecting plate 412 and the second connecting plate 413 are first separated from each other. When the rolling block 411 rolls until the first connecting plate 412 and the second connecting plate 413 are horizontally aligned, the first connecting plate 412 and the second connecting plate 413 are connected, so that the side supports 40 provide lateral support to the side surfaces of the tube segments 60. For pipe segments 60 of different shapes and sizes, when the first connecting plate 412 is moved to be aligned with the second connecting plate 413 in the horizontal direction, the vertical heights of the first connecting plate 412 and the second connecting plate 413 may be different. By connecting the first connecting plate 412 to different height positions on the second connecting plate 413, the side support 40 can provide stable lateral support for pipe segments 60 of different shapes and sizes, effectively improving the flexibility and adaptability of the side support 40.

[0034] In one embodiment, the rolling block 411 is cylindrical and perpendicular to the first connecting plate 412 .

[0035] It can be understood that the axial direction of the rolling block 411 is perpendicular to the first connecting plate 412. When the rolling block 411 rolls along the splicing groove 61, the side of the rolling block 411 abuts against the bottom wall of the splicing groove 61. The axis of the rolling block 411 is perpendicular to the first connecting plate 412, so that the first connecting plate 412 can abut against the side of the pipe segment 60, so that the side support 40 provides lateral support to the pipe segment 60 through the first connecting plate 412 and the second connecting plate 413.

[0036] In one embodiment, a connecting hole 4131 extending vertically is defined in the second connecting plate 413 , and the first connecting plate 412 and the second connecting plate 413 are connected via bolts 4132 passing through the connecting hole 4131 .

[0037] Furthermore, by providing a vertically extending connection hole 4131 on the second connection plate 413, the first connection plate 412 can be connected to the second connection plate 413 at any position along the vertical direction, thereby adapting to pipe segments 60 of different sizes and shapes, thereby improving the versatility and applicability of the bracket.

[0038] In one embodiment, the telescopic support 30 includes a support rod 31, a sleeve 32 and a fastener 33. The bottom of the support rod 31 extends into the sleeve 32 and telescopically cooperates with the sleeve 32. The top of the support rod 31 is supported on the bottom surface of the pipe segment 60. The fastener 33 is passed through the wall of the sleeve 32 and can abut against the side wall of the support rod 31.

[0039] See also Figure 4 The bottom of the support rod 31 extends into the sleeve 32 and forms a telescopic fit with the sleeve 32. The length of the telescopic support 30 can be adjusted by adjusting the length of the bottom of the support rod 31 extending into the sleeve 32, allowing the support rod 31 to fit the bottom of segments 60 of different shapes and sizes. Fasteners 33 are provided through the side of the sleeve 32 and can abut against the sidewall of the support rod 31. When the top of the support rod 31 abuts the segment 60, the fasteners 33 secure the sleeve 32 to the telescopic rod, thereby fixing the length of the telescopic support 30 and providing stable vertical support for the segment 60.

[0040] In one embodiment, the fastener 33 is a screw, and a screw hole that matches the screw thread is defined on the side wall of the sleeve 32 .

[0041] Furthermore, a screw is provided through the side wall of the sleeve 32. By tightening the screw, the end of the screw presses against the side wall of the support rod 31, thereby maintaining the sleeve 32 and the support rod 31 relatively fixed by the screw, thereby maintaining the length of the telescopic support 30 constant. By loosening the screw, the sleeve 32 and the support rod 31 can be moved relative to each other, thereby facilitating adjustment of the length of the support rod 31 extending into the sleeve 32, thereby adjusting the length of the telescopic support 30. The screw arrangement is simple and easy to adjust.

[0042] In one embodiment, the number of the rotating supports 20, telescopic supports 30 and side supports 40 is multiple, and the multiple telescopic supports 30 are supported at intervals in the middle of the bottom surface of the pipe segment 60, the multiple rotating supports 20 are supported at intervals on the edge of the bottom surface of the pipe segment 60, and the multiple side supports 40 are supported at intervals on the side of the pipe segment 60.

[0043] It should be noted that the multiple telescopic supports 30 are arranged in an array and are symmetrically distributed about the axis of symmetry of the segment 60. Similarly, the multiple rotation supports 20 are arranged in an array and are symmetrically distributed about the axis of symmetry of the segment 60. This allows the multiple telescopic supports 30 and the multiple rotation supports 20 to distribute the weight of the segment 60. The multiple side supports 40 are spaced apart along the sides of the segment 60 and provide lateral support to the segment 60 from different directions, thereby maintaining lateral stability. The multiple rotation supports 20, the multiple telescopic supports 30, and the multiple side supports 40 effectively improve the load-bearing capacity and support stability of the bracket.

[0044] In one embodiment, a pad 50 is provided at the top of each of the rotating support 20 and the telescopic support 30. The top of the pad 50 forms an arcuate abutment surface, and the curvature of the abutment surface matches the curvature of the tube segment 60. It will be appreciated that the matching curvature of the top of the pad 50 and the tube segment 60 ensures closer and smoother contact between the pad 50 and the tube segment 60, providing a more uniform supporting force and thereby enhancing the stability of the entire bracket.

[0045] In one embodiment, a gasket 51 is provided between the backing plate 50 and the tube sheet 60 .

[0046] Furthermore, the gasket 51 is flexible. When there is a deviation between the curvature of the tube segment 60 and the curvature of the backing plate 50, the gasket 51 can deform unevenly to ensure that the backing plate 50 fits as closely as possible with the bottom of the tube segment 60, further enhancing the contact compatibility and support stability between the bracket and the tube segment 60. Furthermore, the gasket 51 can buffer the impact force of the tube segment 60 on the backing plate 50, help distribute pressure, reduce local stress concentration, and thus protect the tube segment 60 from damage.

[0047] In one embodiment, the gasket 51 is a rubber gasket 51 or a polyurethane gasket 51. Specifically, the gasket 51 is a conventional rubber gasket 51 or polyurethane gasket 51. The rubber gasket 51 has excellent elasticity and flexibility, effectively adapting to unevenness on the bottom surface of the tube segment 60 and providing uniform support. The polyurethane gasket 51 has excellent wear resistance and strength, and the hardness and elasticity of the polyurethane material can be adjusted as needed. The selection of a rubber gasket 51 or a polyurethane gasket 51 ensures that the gasket 51 effectively cushions the impact of the tube segment 60 on the backing plate 50, thereby providing effective protection for the tube segment 60.

[0048] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
