[0002] With the vigorous advancement of urban modernization and the rapid development of rail transit, subway tunnel construction has become widespread, and the inspection of completed tunnels is a necessary procedure for completion and handover.

[0003] After the tunnel tracks are laid, conventional aerial work platforms cannot cross the tracks, making it impossible to enter the site for inspection. The temporary scaffolding cannot be used for continuous inspection work, which affects subsequent inspection work. The temporary scaffolding wastes materials, consumes a lot of manpower and time, and affects the handover of finished products. Therefore, this utility model provides a multi-functional modular flatbed for tunnel inspection. Utility Model Content

[0015] The sliding frame has a sliding sleeve fixedly installed on its side, which corresponds to the lifting rod. The sliding sleeve slides with the lifting rod, and an insert is provided at the side opening of the sliding sleeve and the lifting rod.

[0016] As a further description of the above technical solution:

[0017] The column support system is fixedly connected to several side bracing systems, which are symmetrically distributed on both sides of the bottom platform.

[0018] As a further description of the above technical solution:

[0019] The operating platform and the side of the column support system are fixedly equipped with climbing ladder components.

[0020] As a further description of the above technical solution:

[0021] A guardrail is fixedly installed on the top of the sliding frame.

[0022] As a further description of the above technical solution:

[0023] The operating platform includes: a base, a fence fixedly connected to the outer edge of the base, and a kick plate fixedly connected to the bottom of the base.

[0024] The beneficial effects of this utility model are:

[0025] This utility model, through the design of a bottom platform, column support system, operating platform, and sliding frame, has wheel axles installed on the bottom platform to cooperate with the track, enabling the whole assembly consisting of the bottom platform, column support system, and operating platform to move along the track, facilitating continuous work for inspection / construction personnel on the operating platform.

[0033] Please refer to the attached document. Figures 1-4 This application illustrates a multifunctional modular flatbed for tunnel inspection, which provides a continuous walking platform for inspection / construction personnel during the inspection process after tunnel track laying. The flatbed includes: a bottom frame 1, a column support system 3, an operating platform 4, and a sliding frame 6.

[0034] The bottom platform 1 is equipped with wheel axles that cooperate with the track, enabling the bottom platform 1 to move on the track. The operating platform 4 is located above the bottom platform 1, and a column support system 3 is fixedly connected between the operating platform 4 and the bottom platform 1. The whole consisting of the bottom platform 1, the column support system 3, and the operating platform 4 can move along the track. The column support system 3 is used to raise and support the operating platform 4. The operating platform 4 is used by inspection / construction personnel. A notch is provided in the middle of the operating platform 4, and a sliding frame 6 that slides up and down is provided in the notch. A height-adjustable structure is provided between the sliding frame 6 and the operating platform 4. The sliding frame 6 further serves as an auxiliary platform. When inspecting / maintaining part of the structure at the top of the tunnel, the auxiliary platform provided by the sliding frame 6 is more convenient to use. The user can adjust the height of the top of the sliding frame 6 by adjusting the height-adjustable structure to meet the needs of use in some complex situations (due to the limitation of movement in continuous tunnels, the overall structure of the bottom platform 1, the column support system 3, and the operating platform 4 cannot be designed too high, otherwise, collision accidents may easily occur at the top in some inclined tracks).

[0035] In one embodiment, the wheel axle has a hydraulic clamping function, specifically designed with a self-locking device (release brake). When movement is not required, the hydraulic self-locking device can firmly clamp the track, preventing the bottom frame 1, column support system 3, operating platform 4 and sliding frame 6 from sliding as a whole, thus ensuring the safety of use.

[0036] In one embodiment, the height-adjustable structure includes: a boom 5, the top of which is fixedly connected to the bottom of the operating platform 4, and the boom 5 has a plurality of side openings 5a on its side. A sliding sleeve corresponding to the boom 5 is fixedly provided on the side of the sliding frame 6. The sliding sleeve slides with the boom 5, and an insert is provided at the side opening 5a of the sliding sleeve and the boom 5.

[0037] The user pulls out the insert block and can adjust the height of the sliding frame 6 up and down. When the height is adjusted to a suitable level (the corresponding part on the sliding sleeve should be aligned with one of the side openings 5a), the user inserts the insert block into the side opening 5a of the sliding sleeve and the hanging rod 5 to fix the sliding frame 6 and the hanging rod 5 together.

[0038] In one embodiment, a plurality of side bracing systems 2 are fixedly connected to the side of the column support system 3. The plurality of side bracing systems 2 are symmetrically distributed on both sides of the bottom platform 1. The side bracing systems 2 are used to further ensure the overall stability of the bottom platform 1, column support system 3, operating platform 4 and sliding frame 6, and to avoid the danger of tilting. The side bracing systems 2 are assembled and can be disassembled to avoid affecting the overall movement of the bottom platform 1, column support system 3, operating platform 4 and sliding frame 6 in some narrow spaces.

[0039] In one embodiment, a ladder assembly 7 is fixedly installed on the side of the operating platform 4 and the column support system 3, allowing inspection / construction personnel to go up and down the operating platform 4 via the ladder assembly 7, thereby increasing the ease of use.

[0040] In one embodiment, a guardrail 6a is fixedly installed on the top of the sliding frame 6. The guardrail 6a moves up and down with the sliding frame 6 and is used to protect the inspection / construction personnel on the sliding frame 6.

[0041] In one embodiment, the operating platform 4 includes: a base 401, a fence 402 fixedly connected to the outer edge of the base 401, and a kick 403 fixedly connected to the bottom of the base 401. The base 401 is a frame structure, providing a stable support surface, and a steel plate is fixed to the top of the frame structure. The fence 402 is used to protect the inspection / construction personnel on the base 401, and reflective sheets can be attached to the outside of the kick 403 to serve as a danger warning.
