It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0037] In the following description, a large number of specific details are set forth in order to facilitate a thorough understanding of the present disclosure, but the present disclosure can also be implemented in other different manners from those described herein; obviously, the embodiments described in the specification are only a part of the embodiments of the present disclosure, and not all the embodiments.

[0038] It should be noted that, in this document, relational terms such as "first" and "second", and the like, are used solely to distinguish one entity or action from another entity or action, without necessarily requiring or implying any actual such relationship or order between such entities or actions. Moreover, the terms "comprises", "comprising", or any other variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but can include other elements not expressly listed or inherent to such process, method, article, or apparatus.

[0039] As Figure 1As shown, the tunnel maintenance train provided by the present disclosure comprises a transportation power module 1, an auxiliary chiseling module 2, a working platform trailer module 3 and a concrete construction module 4. The transportation module 1 comprises a transportation power vehicle 11 and a plurality of bearing mechanisms 12. Preferably, the bearing mechanism 12 can be a tunnel standard trolley or a bearing trolley for road use, so as to meet the requirements of different working conditions. The auxiliary chiseling module 2, the working platform trailer module 3 and the concrete construction module 4 are sequentially arranged on the plurality of bearing mechanisms 12. In some embodiments of the present disclosure, the above modules can be adjusted in sequence on the bearing mechanism 12 according to different construction requirements to meet the requirements. Preferably, the transportation power vehicle 11 of the present disclosure is arranged at the end of the vehicle body connected by the plurality of bearing mechanisms 12. It can pull the rear bearing mechanism 12 on the track (front drive), or it can push the plurality of bearing mechanisms 12 (rear drive) at the rear end of the vehicle body connected by the plurality of bearing mechanisms 12. In a preferred embodiment of the present disclosure, the transportation power vehicle 11 is arranged at the front and rear ends of the vehicle body connected by the plurality of bearing mechanisms 12, so as to meet the power requirements and continue to provide power when one of the transportation power vehicles 11 fails. In the embodiments of the present disclosure, the transportation power vehicle 11 is provided with a staff seat cabin.

[0040] The auxiliary chiseling module 2 of the present disclosure comprises a bottom displacement platform 21 and a chiseling mechanical arm 22. The optional bottom displacement platform 21 is arranged on the bearing surface of the bearing mechanism 12, and the chiseling mechanical arm 22 is arranged on the bottom displacement platform 21. The bottom displacement platform 21 of the present disclosure is used to drive the chiseling mechanical arm 22 to move to the range outside the bearing mechanism 12. In some embodiments, the bottom displacement platform 21 and the bearing mechanism 12 are connected through a rotary table. The rotary table can drive the bottom displacement platform 21 to rotate horizontally relative to the bearing mechanism 12. According to different tunnel specifications, the position of the chiseling mechanical arm 22 driven by the bottom displacement platform 21 is different. Preferably, the bottom displacement platform 21 drives the chiseling mechanical arm 22 to rotate to the center point of the tunnel, so that the chiseling range of the chiseling mechanical arm can cover the walls on both sides and the top side for construction;

[0041] In an embodiment of the present disclosure, the connection position of the chiseling mechanical arm 22 and the bottom displacement platform 21 is provided with a second rotary table. The second rotary table drives the chiseling mechanical arm 22 to rotate horizontally to facilitate the construction of other ranges in the extension direction of the tunnel wall;

[0042] Optionally, in another embodiment of the present disclosure, a slide rail is arranged on the bottom displacement platform 21 and the chiseling mechanical arm 22. The chiseling mechanical arm is arranged on the slide rail, and the sliding direction of the slide rail is perpendicular to the extension direction of the bottom displacement platform 21. When the bottom displacement platform 21 is displaced to the direction perpendicular to the bearing mechanism 12, the slide rail is parallel to the bearing mechanism 12 at this time. The chiseling mechanical arm 22 slides in the extension direction of the tunnel through the slide rail to meet the larger chiseling range.

[0043] Optionally, in a preferred embodiment of the present disclosure, a sliding block is arranged on the sliding rail, and the chiseling mechanical arm 22 is connected with the sliding block through the second turntable. In this way, the chiseling mechanical arm 22 can slide in the extension direction of the tunnel and can also be horizontally rotated through the second turntable.

[0044] The working platform trailer module 3 comprises a main platform mechanism 31, a folding platform mechanism 32 and a rotary support mechanism 33. The main platform mechanism 31 comprises a first platform 311, a second platform 312 and a main support frame 313. The first platform 311 is arranged on the side of the main support frame 313 close to the ground of the tunnel, and the second platform 312 is arranged on the side of the main support frame 313 close to the top of the tunnel, forming a double-layer structure of the main platform mechanism. A staircase is arranged between the first platform 311 and the second platform 312. The first platform 311 is arranged on the rotary support mechanism 33, which is used to be rotationally connected with the bearing mechanism. The rotary support mechanism 33 enables the main platform mechanism to rotate relative to the bearing mechanism 12. The folding platform mechanism 32 is arranged on the main platform mechanism 31. The folding platform mechanism 32 arranged on the main platform mechanism can be unfolded after the bearing mechanism 12 reaches the designated construction position, so as to increase the number of layers of the working platform.

[0045] In some embodiments of the present disclosure, the folding platform mechanism comprises a first support 321 and a third platform 322. The first support 321 is connected between the third platform 322 and the side of the main platform mechanism 31 away from the ground. Specifically, the first support 321 can be a telescopic mechanism or a folding mechanism, so that the third platform 322 is close to the main platform mechanism in the transportation state, and the folding working platform can pass through the tunnel. Optionally, the third platform 322 is arranged in parallel with the second platform 312, and a telescopic mechanism, which can be a hydraulic mechanism, a multi-link telescopic mechanism, etc., is arranged between the third platform 322 and the second platform 312. Optionally, the first support 321 can also be a sliding rail hinged with the main platform mechanism 31. During transportation, the first support 321 is parallel with the second platform 312. When reaching the designated construction site, the first support 321 is fixed vertically with the second platform 312. Then, the third platform 322 is installed on the sliding rail, and the lifting of the third platform 322 is controlled through the sliding rail. Specifically, by using the telescopic or folding third platform 322, the feasibility of transporting the working platform in the tunnel can be ensured, and the height of the working platform after unfolding can meet the construction requirements.

[0046] The third platform 322 comprises two third platform plates D, which are symmetrically arranged about the center axis in the extension direction of the second platform 312, and each of the third platform plates D and the first support 321 can be flipped to the side of the main platform mechanism 31, and in the transportation process, the third platform plates D and the first support 321 are hung on both sides of the main platform mechanism 31. Preferably, the first support 321 is provided with a locking mechanism at the hinge with the third platform plate D and the main support frame 313, which is used to fix the hinge during construction to avoid instability of the third platform 322 during construction.

[0047] In a preferred embodiment, the first platform 311 and the second platform 312 are respectively hinged with a first extension plate and a second extension plate at the edges thereof, which are used to increase the area of the first platform 311 and the second platform 312 after being unfolded. Specifically, since the main platform mechanism 31 is a fixed structure, the first platform 311 and the second platform 312 accommodate personnel and tools therebetween. In more detail, the foldable working platform 32 further comprises a foldable ladder, which is used to connect the third platform 322 with the main platform mechanism 31 after the working platform is unfolded. The foldable working platform 32 described above can meet the size requirements of railway transportation in the tunnel when being folded, and the main platform mechanism 31 can be rotated to a state of crossing two tracks through the rotary support mechanism 33, and the construction can be performed after the foldable platform mechanism 32 is unfolded. The platform can be unfolded or folded in a very short time, and workers do not need to build a temporary simple working platform in the tunnel, which saves a large amount of labor and construction time.

[0048] In some embodiments of the present disclosure, the chiseling robot arm 22 comprises a rotating part 221 connected with the bottom displacement platform 21, a first counterbalance arm 222, a second counterbalance arm 223, a first telescopic part 224, a second telescopic part 225, a third telescopic part 226, a connecting part 227, and a mounting shell 228. One end of the first counterbalance arm 222 is horizontally hinged to one end of the rotating part 221 close to the top of the tunnel, so that the first counterbalance arm 222 can rotate in the vertical direction. The opposite end is connected with the second counterbalance arm 223 through a telescopic oil cylinder, so that the second counterbalance arm 223 can be telescoped relative to the first counterbalance arm 222 to meet the chiseling construction of a far range of the tunnel wall. One end of the first telescopic part 224 is horizontally hinged to one end of the rotating part 221 close to the bottom of the tunnel. The connection end of the first counterbalance arm 222 and the connection end of the first telescopic part 224 on the rotating part 221 are relatively far away. The opposite end of the first telescopic part 224 is horizontally hinged to the first counterbalance arm 222, so that the first telescopic part 224 can drive the first counterbalance arm 222 to lift up when it is extended. Both ends of the connecting part 227 in the Y-axis direction are respectively horizontally hinged to the second counterbalance arm 223 and the second telescopic part 225. The opposite end of the second telescopic part 225 hinged to the connecting part 227 is horizontally hinged to the second counterbalance arm 223. One end of the mounting shell 228 is open and connected with the opposite face to the opening. The milling head 12 is arranged in the mounting shell 228, and one end of the milling head 12 is exposed from the opening of the mounting shell 228, so that the milling head 12 can move up and down in the Y-axis direction when the second telescopic part 225 is extended, to adapt to tunnel wall surfaces of various angles. The mounting shell 228 is vertically hinged to the connecting part 227, so that the mounting shell 228 can swing left and right to drive the milling head to adjust the position. One end of the third telescopic part 226 is vertically hinged to the connecting face of the mounting shell 228 and the connecting part 227. The opposite end is vertically hinged to the connecting part 227. The third telescopic part 226 is symmetrically arranged in the X-axis direction. The connecting part 227 is between the plurality of third telescopic parts 226. In the preferred embodiment of the present disclosure, the number of third telescopic parts 226 is two and arranged on both sides of the connecting part 227. After the mechanical arm 11 completes the first-stage chiseling construction, the second rotating table 22 needs to be rotated and displaced to the left and right sides. The milling head 12 and the tunnel wall surface are not in parallel. At this time, the third telescopic part 226 on the left side or the right side of the connecting part 227 makes the chiseling surface of the milling head swing in the horizontal direction to keep parallel with the tunnel wall, which can well improve the chiseling quality.

[0049] In some embodiments of the present disclosure, the working platform trailer module is further provided with a material delivery mechanism 34, which comprises a material placing groove 341 and a grabbing and conveying mechanism 342 arranged on both sides of the material placing groove 341.
