[0033] Embodiment: As Figures 1-13 shown, this embodiment relates to a method for quickly installing a pipeline maintenance platform in a shield tunnel, and the method includes the following steps:

[0034] S1: Install a platform bracket at one end of the pipeline 13.

[0035] As Figures 1-6 shown, the platform bracket is a foldable structure, and each platform bracket includes a vertical pole 1, at least one brace, two fixing parts, a pedal support, and a pedal brace 5. The vertical pole 1 is leaned against the outer wall of the pipeline 13 and the inner wall of the pipe segment 19. One end of the brace is movably connected to one side of the vertical pole 1 and is located in the middle of the vertical pole 1, and the other end of the brace can be supported on the inner wall of the pipe segment 19. The fixing parts and the brace are on the same side of the vertical pole 1, and the two fixing parts are respectively arranged at both ends of the vertical pole 1 for connecting and fixing the tightening belt. The tightening belt is tightly wound around the outer wall of the pipeline 13, and both ends of the tightening belt are respectively connected to the two fixing parts, so that the vertical pole 1 is fastened to the pipeline 13 and the pipe segment 19, and the brace is fastened to the pipe segment 19. One side of the pedal support and the pedal brace 5 are both movably connected to the other side of the vertical pole 1, and the pedal brace 5 is arranged at the bottom end of the vertical pole 1, and the pedal support is located above the pedal brace 5. A limiting device is arranged at the bottom of the pedal support, and the pedal brace 5 cooperates with the limiting device to keep the pedal support in a horizontal state for installing the platform pedal 16. In this embodiment, the fixing part is an eyebolt 2, the tightening belt is a ratchet tightening belt 15, the number of braces is two, which are the long vertical pole brace 11 and the short vertical pole brace 12 respectively. The vertical pole 1 is movably connected to the long vertical pole brace 11, the short vertical pole brace 12, the pedal support, and the pedal brace 5 respectively through the ratchet assembly 3. The support angles of the pedal brace 5, the long vertical pole brace 11, and the short vertical pole brace 12 are adjusted through the ratchet assembly 3 to adapt to different tunnel diameters and keep the pedal support horizontal, establishing a good working surface. The adjustable reverse self-locking characteristic of the ratchet assembly 3 makes the support structure more stable, and the long vertical pole brace 11 and the short vertical pole brace 12 respectively support on the inner wall of the pipe segment 19 in the directions of both sides of the pipeline 13, which can improve the stability of the platform bracket.

[0036] As Figure 3 、 Figure 4 、 Figure 5 and Figure 6As shown, protective sleeves 4 are provided at the ends of the long vertical strut 11, the short vertical strut 12, and the vertical pole 1. The protective sleeve 4 is used to protect the segment 19 and prevent the long vertical strut 11, the short vertical strut 12, and the vertical pole 1 from damaging the inner wall of the segment 19.

[0037] As Figures 6-9 shown, the pedal support includes a support body, a first stop block 7, a second stop block, and a guardrail socket 8. The first stop block 7 and the second stop block are respectively provided at both ends of the support body, and the second stop block is spaced a certain distance from the end of the support body close to the vertical pole 1. A groove for placing the platform pedal 16 is formed among the first stop block 7, the second stop block, and the support body, and the platform pedal 16 can be installed in this groove. The guardrail socket 8 is provided outside the first stop block 7. The top of the guardrail socket 8 is higher than the top of the first stop block 7 and is used for installing the guardrail 14. And a sealing plate is provided at the bottom of the guardrail socket 8 to support the guardrail 14 and keep the guardrail 14 horizontal. The limiting device is a stepped card slot 10, that is, a stepped card slot 10 is provided at the bottom of the support body. The pedal brace 5 can be clamped in the card slot 10 to keep the support body in a horizontal state. And due to the action of gravity, after maintenance personnel stand on the platform, the engagement between the pedal brace 5 and the card slot 10 will be tighter and the connection will be more stable. In this embodiment, the support body is a butt-welded angle steel, and when multiple platforms are connected in series, the pedal supports can be connected together.

[0038] Specifically, lean the vertical pole 1 against the outer wall of the pipeline 13 and the inner wall of the segment 19, open the pedal support, and make the pedal brace 5 clamped in the card slot 10 at the bottom of the pedal support to keep the pedal support in a horizontal state; adjust the positions of the long vertical strut 11 and the short vertical strut 12 through the ratchet assembly 3 to make the long vertical strut 11 and the short vertical strut 12 reliably support on the inner wall of the segment 19; wind the ratchet tightening belt 15 tightly around the outer wall of the pipeline 13, and make both ends of the ratchet tightening belt 15 connected to the two eyebolt 2 respectively, so as to fix the vertical pole 1 to the pipeline 13 and the segment 19.

[0039] S2: According to the installation method in step S1, install another platform bracket at the corresponding position at the other end of the pipeline 13.

[0040] S3: Install the platform pedal 16 on the pedal support of the platform bracket.

[0041] As Figures 7-9As shown, the platform pedal 16 is a foldable structure formed by several platform pedal components. The platform pedal components are connected by hinges 24. Each platform pedal component includes two long angle steels 26, two short angle steels 27, and an anti-slip net 29. The anti-slip net 29 is arranged in the rectangular space formed by the enclosure of the long angle steels 26 and the short angle steels 27. The long angle steels 26 are reinforced by longitudinal reinforcing angle steels 25, and the short angle steels 27 are reinforced by transverse reinforcing angle steels 28. In this embodiment, the number of platform pedal components is two. Of course, the platform pedal 16 can also be an integral structure.

[0042] Specifically, unfold the platform pedal 16 and fix it in the groove formed among the first stop block 7, the second stop block, and the butt-welded angle steel of the pedal support.

[0043] S4: Install the guardrail 14 on the pedal support of the platform bracket.

[0044] As Figures 10-13 shown, the guardrail 14 is a detachable structure, which is sequentially spliced by a first guardrail component, a second guardrail component, and a third guardrail component. The first guardrail component includes a left guardrail sub-block 17, a bolt 21, and a bolt socket 18. The second guardrail component includes a middle guardrail sub-block 20 and a bolt 21. The third guardrail component includes a right guardrail sub-block 22 and a bolt socket 18. Among them, the bolt 21 and the bolt socket 18 of the first guardrail component are respectively arranged on both sides of the left guardrail sub-block 17. The bolts 21 of the second guardrail component are respectively arranged on both sides of the middle guardrail sub-block 20. The bolt sockets 18 of the third guardrail component are respectively arranged on both sides of the right guardrail sub-block 22. The bolt sockets 18 of the first guardrail component and the third guardrail component cooperate with the bolts 21 of the second guardrail component to connect the first guardrail component, the second guardrail component, and the third guardrail component together. Both the left guardrail sub-block 17 and the right guardrail sub-block 22 include two cross bars, several short longitudinal bars, and one long longitudinal bar. The middle guardrail sub-block 20 includes two cross bars and several short longitudinal bars. The long longitudinal bars of the left guardrail sub-block 17 and the right guardrail sub-block 22 can be inserted into the guardrail sockets 8 of the pedal support to fix the guardrail 14. And when multiple platforms are connected in series, the guardrails 14 are connected by the cooperation of the bolts 21 of the first guardrail component and the bolt sockets 18 of the third guardrail component. Of course, the guardrail 14 can also be an integral structure.

[0045] Specifically, assemble the guardrail 14 and insert the long longitudinal bars of the first guardrail component and the third guardrail component on the guardrail 14 into the guardrail sockets 8 of the pedal support. After the installation of the platform is completed, the pipeline maintenance process can be carried out.

[0046] In addition, connecting multiple platforms in series can form a longer working surface to meet different working conditions and improve its practicability.

[0047] Although the above embodiments have detailed the concept and embodiments of the present invention with reference to the accompanying drawings, those of ordinary skill in the art can recognize that various improvements and transformations can still be made to the present invention without departing from the scope defined by the claims, so they will not be elaborated here one by one.
