[0002] Tunnel boring machine (TBM) segments are precast concrete components used in shield tunneling to support and protect underground tunnels. TBM segments are usually arc-shaped and are made up of multiple segments spliced ​​together to form a complete circular or elliptical tunnel lining. Moreover, TBM segments are prefabricated and installed directly inside the tunnel during the excavation process of the TBM.

[0003] During the prefabrication process of tunnel boring machine (TBM) segments, after grouting, the TBM segments need to undergo surface finishing.

[0016] The servo motor drives the gear disk to rotate on the gear guide rail, which in turn drives the light-collecting plate and the side light-surface support block to move smoothly to perform the light-surface operation. No manual operation is required, which ensures the consistency and accuracy of the light-surface processing. The coordinated work of the light-collecting plate and the side light-surface support block can perform comprehensive light-surface processing on the top and sides of the shield tunnel segment, avoiding the problem of inconsistent quality in manual light-surface processing, and making the surface of the tunnel segment smoother and flatter.

[0017] Compared with traditional manual surface finishing, this device greatly shortens the surface finishing time.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figure 1 , Figure 3This invention provides an embodiment of a subway tunnel segment prefabrication and processing device, comprising a support positioning mechanism 1, a transport mechanism 2, a support guiding mechanism 3, a smoothing mechanism 4, and a PLC control box 5. The support positioning mechanism 1 includes a support base 11. The PLC control box 5 is fixedly installed at the top of the support base 11. Two first fixing plates 12 are symmetrically fixedly installed at the top of the support base 11. Two first electro-hydraulic rods 13 are symmetrically fixedly installed at the top of the first fixing plates 12. Two guide rails 14 are symmetrically fixedly installed at the top of the support base 11. A second fixing plate 15 is fixedly installed at the middle of one end of the top of the support base 11. A second electro-hydraulic rod 16 is fixedly installed on the second fixing plate 15. Two limiting slide rods 17 are symmetrically fixedly installed on the second fixing plate 15. The two limiting slide rods 17 are slidably connected to... A sliding plate 18 is rotatably connected to a positioning plate 19 at its top via a spring hinge. The spring hinge facilitates the rebound of the positioning plate 19. A support block 110 is fixedly connected to the other end of the top of the support base 11. The support block 110 has symmetrically formed first limiting grooves 111 on both sides. A third electric hydraulic rod 112 is fixedly installed inside the support block 110. A positioning sliding frame 113 is slidably connected to the top of the support base 11 outside the support block 110. Two limiting sliders 114 are symmetrically fixedly connected to the inner side of the positioning sliding frame 113. The limiting sliders 114 are slidably connected to the inner side of the first limiting groove 111. The positioning sliding frame 113 is limited by the limiting sliders 114 being slidably connected to the inner side of the first limiting groove 111, and the positioning sliding frame 113 is supported by the support block 110.

[0028] Both guide rails 14 are located inside the two first fixed plates 12. The second fixed plate 15 and the positioning sliding frame 113 are both located inside the two guide rails 14. The telescopic end of the second electro-hydraulic rod 16 is fixedly installed on the side of the sliding plate 18 near the second electro-hydraulic rod 16. The telescopic movement of the second electro-hydraulic rod 16 pushes the sliding plate 18 to slide on the limiting slide rod 17. The telescopic end of the third electro-hydraulic rod 112 is fixedly installed at the top of the inside of the positioning sliding frame 113. The telescopic movement of the third electro-hydraulic rod 112 drives the positioning sliding frame 113 to slide in the support base 11, and the positioning sliding frame 113 and the positioning plate 19 are used to position and fix the transport vehicle 21.

[0029] See Figure 4 , Figure 5 , Figure 6The transport mechanism 2 includes a transport vehicle 21. The top of the transport vehicle 21 is provided with a placement groove 22. The bottom of the transport vehicle 21 is uniformly fixed with concave rollers 23. The concave rollers 23 roll on the top of the guide rail 14, thereby driving the transport vehicle 21 to move. Two pull rings 24 are fixedly connected to both ends of the transport vehicle 21, which facilitates the movement of the transport vehicle 21. The inner side of the placement groove 22 is provided with a mold 25, and the inner side of the mold 25 is provided with shield tunnel segments 26. The transport vehicle 21 is connected to the top of the guide rail 14 by rolling the concave rollers 23.

[0030] Two symmetrical support and guide mechanisms 3 are provided. The support and guide mechanism 3 includes a fixed bracket 31. Lifting ears 32 are fixedly connected to both ends of the fixed bracket 31. A guide arc plate 33 is fixedly installed at the top of the fixed bracket 31. A gear guide rail 36 is fixedly installed at the top of one side of the guide arc plate 33. A guide groove 34 is opened through the guide arc plate 33 near the gear guide rail 36. Two second limiting grooves 35 are opened on the side of the guide arc plate 33 near the gear guide rail 36. The two second limiting grooves 35 are symmetrically distributed at the top and bottom of the guide groove 34. The design of the guide groove 34 and the second limiting groove 35 facilitates the guiding and sliding of the smooth surface mechanism 4.

[0031] The smoothing mechanism 4 includes a mounting plate 41 for support and fixation. The two ends of the mounting plate 41 are symmetrically arranged. Limiting blocks 42 are fixedly connected to both ends of the mounting plate 41. A sliding block 43 is fixedly connected to the middle of the end of the limiting block 42 away from the mounting plate 41. A limiting slide plate 44 is fixedly installed at the end of the sliding block 43 away from the limiting block 42. A servo motor 45 is fixedly installed on the side of the limiting slide plate 44 away from the sliding block 43. A gear disk 46 is fixedly installed at the drive end of the servo motor 45. A light-collecting plate 47 is fixedly installed at the bottom end of the mounting plate 41. Side smoothing support blocks 48 are fixedly installed at both ends of the bottom end of the light-collecting plate 47. The light-collecting plate 47 and the side smoothing support blocks 48 are used for smoothing operations. The installation method facilitates disassembly for later maintenance.

[0032] See Figure 7The smoothing mechanism 4 is located between two supporting guide mechanisms 3. The sliding block 43 is slidably connected to the inner side of the guide groove 34. The limiting slide plate 44 is slidably connected to the inner side of the second limiting groove 35 on the side near the sliding block 43. The limiting block 42 is slidably connected to the side of the guide arc plate 33 away from the gear guide rail 36 on the side near the sliding block 43. The sliding block 43 is limited by the limiting block 42 and the limiting slide plate 44. The smoothing plate 47 and the two side smoothing support blocks 48 are located between the two guide arc plates 33. The gear disk 46 is meshed and connected to the top of the gear guide rail 36. The gear disk 46 is driven to rotate by the drive end of the servo motor 45, thereby causing the servo motor 45 to drive the limiting slide plate 44 to move, thereby driving the smoothing plate 47 and the side smoothing support blocks 48 to move for smoothing operations. The telescopic end of the first electro-hydraulic rod 13 is fixedly installed at the bottom end of the lifting ear 32. The telescopic movement of the first electro-hydraulic rod 13 pushes the lifting ear 32 to move, thereby adjusting the height of the smoothing plate 47.

[0033] See Figure 2 , Figure 3 , Figure 4 and Figure 6 The PLC control box 5 is electrically connected to the first electro-hydraulic rod 13, the second electro-hydraulic rod 16, the third electro-hydraulic rod 112 and the servo motor 45. Automatic surface finishing can be performed by setting the program through the PLC control box 5, which is simple to operate and improves work efficiency.

[0034] The bottom of the side smooth surface support block 48 is arc-shaped, and the bottom ends of the two side smooth surface support blocks 48 are slidably connected to the top ends of both sides of the mold 25. The height of the top end of the shield tunnel segment 26 is locked by the distance between the bottom end of the side smooth surface support block 48 and the top ends of both sides of the mold 25 and the bottom end of the smooth plate 47 and the bottom end of the side smooth surface support block 48, thereby ensuring the uniformity of the height of the shield tunnel segment 26. At the same time, the side of the side smooth surface support block 48 smooths the side of the shield tunnel segment 26. The two side smooth surface support blocks 48 are slidably connected to both sides of the shield tunnel segment 26 on the side near the middle of the smooth plate 47. The two sides of the smooth plate 47 are designed to be inclined upwards, and the bottom end of the smooth plate 47 is slidably connected to the top end of the shield tunnel segment 26. The inclined design facilitates the pressing of concrete and the replenishment of excess concrete to the position where there is insufficient concrete.

[0035] Working principle: During use, the control program is first set through the PLC control box 5. When a smooth surface operation is required, the transport vehicle 21 is moved on the guide rail 14 by external force. When the transport vehicle 21 moves to the fixed bracket 31, the third electro-hydraulic rod 112 is extended by the PLC control box 5. The extension end of the third electro-hydraulic rod 112 pushes the positioning sliding frame 113 upward until the top of the positioning sliding frame 113 is higher than the bottom of the transport vehicle 21. When the transport vehicle 21 moves to the positioning plate 19, the transport vehicle 21 pushes the positioning plate 19 to rotate away from the second electro-hydraulic rod 16. Then the positioning plate 19 is pushed to... At the bottom of the transport vehicle 21, when the transport vehicle 21 moves to the outside of the positioning sliding frame 113, the positioning plate 19 disengages from the bottom of the transport vehicle 21. Under the action of the spring hinge, the positioning plate 19 returns to the vertical state. Then, the PLC control box 5 controls the extension of the second electro-hydraulic rod 16. The extension end of the second electro-hydraulic rod 16 pushes the sliding plate 18 to slide on the limit sliding rod 17 and approach the transport vehicle 21 until the end of the positioning plate 19 away from the second electro-hydraulic rod 16 is close to the end of the transport vehicle 21. At this time, the shield tunnel segment 26 on the transport vehicle 21 is fixed, and the top of the shield tunnel segment 26 is located at the bottom of the moving path of the light-collecting plate 47.

[0036] Then, the top part of the shield tunnel segment 26 can be smoothed. At this time, the PLC control box 5 controls the first electro-hydraulic rod 13 to retract. The extension end of the first electro-hydraulic rod 13 drives the lifting ear 32 to move downward. The movement of the lifting ear 32 drives the fixed bracket 31 to move downward. The movement of the fixed bracket 31 drives the guide arc plate 33 to move downward. The movement of the guide arc plate 33 drives the mounting plate 41 to move downward, thereby driving the finishing plate 47 and the side smooth surface support block 48 to move downward until the bottom end of the side smooth surface support block 48 is close to the top of both sides of the mold 25, and the bottom end of the finishing plate 47 is close to the top of the shield tunnel segment 26. Then, the PLC control box 5 controls the servo motor 45 to start. The drive end of the servo motor 45 drives the gear disk 46 to rotate. Due to the meshing connection of the gear disk 46, At the top of the gear guide rail 36, the rotating gear disk 46 drives the servo motor 45 to move. The movement of the servo motor 45 drives the limiting slide plate 44 to move, thereby driving the mounting plate 41 to move. Since the sliding block 43 is slidably connected inside the guide groove 34 and is limited by the limiting block 42 and the limiting slide plate 44, the two ends of the mounting plate 41 move smoothly. The movement of the mounting plate 41 drives the light-collecting plate 47 and the side light surface support block 48 to move at the top and outside of the shield tunnel segment 26. The light-collecting plate 47 moves at the top of the shield tunnel segment 26 to perform light-collecting operation at the top of the shield tunnel segment 26. The side light surface support blocks 48 located on both sides of the shield tunnel segment 26 perform light-collecting operation on the sides of the shield tunnel segment 26. The light-collecting operation can be completed by repeatedly moving multiple times.

[0037] After the smoothing of the shield tunnel segment 26 is completed, the PLC control box 5 controls the first electro-hydraulic rod 13 to extend. The extension end of the first electro-hydraulic rod 13 pushes the lifting ear 32 to move upward. The movement of the lifting ear 32 causes the fixed bracket 31 to move upward. The movement of the fixed bracket 31 causes the guide arc plate 33 to move upward. The movement of the guide arc plate 33 causes the mounting plate 41 to move upward, thereby causing the finishing plate 47 and the side smooth surface support block 48 to move upward until the bottom of the finishing plate 47 is higher than the highest point of the top of the shield tunnel segment 26. At the same time, the PLC control box 5 controls the third electro-hydraulic rod 112 and the second electro-hydraulic rod 16 to retract. The extension end of the third electro-hydraulic rod 112 causes the positioning sliding frame 113 to move downward to the bottom of the transport vehicle 21. The extension end of the second electro-hydraulic rod 16 causes the sliding plate 18 to return to the initial position. Then, the transport vehicle 21 is pulled by external force to continue to move to a position away from the fixed bracket 31 for manual micro-finishing and finishing.
