[0029] In shield tunnel construction, segments serve as key structural support components for tunnel stability and strength. Segments are cast using concrete. During this process, the segments undergo a surface finishing treatment to ensure quality. In current segment production processes, this finishing process is typically performed manually, resulting in low efficiency and significant human influence, leading to poor segment quality.

[0030] The present invention provides a segment finishing device 100 .

[0031] See also Figures 1 to 3 In one embodiment of the present invention, the segment finishing device 100 includes a base 10, a traveling frame 20, a lifting mechanism 30 and a segment finishing mechanism 40: the base 10 includes base frames 11 spaced apart in the longitudinal direction, a working position 12 for placing the segment is formed between the two base frames 11, and each base frame 11 extends in the transverse direction; the traveling frame 20 extends in the longitudinal direction, and the two ends of the traveling frame 20 in the longitudinal direction are respectively installed on the two base frames 11 and are located above the working position 12, and the two ends of the traveling frame 20 in the longitudinal direction can respectively move in the transverse direction on the two base frames 11; the lifting mechanism 30 and the segment finishing mechanism 40 are configured as follows: The lowering mechanism 30 is installed on the traveling frame 20 and can move longitudinally on the traveling frame 20; the surface collecting mechanism 40 includes a mounting seat 41, a leveling component 42 and a film covering component 43. The mounting seat 41 is installed on the lifting mechanism 30, and the leveling component 42 and the film covering component 43 are both installed on the mounting seat 41. The lifting mechanism 30 can drive the mounting seat 41 to rise and fall, so as to drive the leveling component 42 and the film covering component 43 to separate from or abut against the surface of the pipe segment. The leveling component 42 is used to level the surface of the pipe segment, and the film covering component 43 is used to cover the surface of the pipe segment with a protective film 60.

[0032] Horizontal Figure 1 The left and right directions in the vertical direction are Figure 1 The front-to-back direction.

[0033] The technical solution of the present invention is to place the pipe segment in the working position 12, and the lifting mechanism 30 drives the leveling assembly 42 and the coating assembly 43 to descend to abut the surface of the pipe segment. Then, the traveling frame 20 drives the leveling assembly 42 and the coating assembly 43 to move in the left and right directions. The leveling assembly 42 abutting the surface of the pipe segment can level the surface of the pipe segment to improve the flatness of the pipe segment, thereby improving the quality of the pipe segment after forming. The coating assembly 43 then covers the surface of the flattened pipe segment with a protective film 60. The protective film 60 can effectively reduce the loss of water during the setting of concrete, effectively avoid cracking of the pipe segment after forming, and further improve the forming quality of the pipe segment. The pipe segment finishing device 100 provided by the present invention can level and coat the surface of the pipe segment, realizing mechanized surface finishing of the pipe segment, eliminating the need for manual surface finishing of the pipe segment, achieving higher finishing efficiency and being unaffected by human factors. The treatment effect on the pipe segment is stable, effectively improving the forming quality of the pipe segment.

[0034] In one embodiment of the present invention, the leveling assembly 42 includes a leveling roller 421 extending in the transverse direction. The leveling roller 421 extends in the longitudinal direction and is rotatably mounted on the bottom of the mounting base 41 around its extension direction. The leveling roller 421 can abut against the surface of the pipe segment to level the surface of the pipe segment.

[0035] Specifically, the leveling roller 421 is brought into contact with the surface of the pipe segment, and the traveling frame 20 drives the leveling roller 421 to move in the left and right directions. The leveling roller 421 moving in the left and right directions can roll from one end of the surface of the pipe segment in the left and right directions to the other end of the surface of the pipe segment in the left and right directions, thereby achieving the leveling of the surface of the pipe segment, which is simple and convenient.

[0036] In one embodiment of the present invention, the coating assembly 43 includes a film winding roller 431 and a compacting roller 432. The film winding roller 431 extends longitudinally and is installed at the bottom of the mounting seat 41 so as to be rotatable around its axial direction. The compacting roller 432 extends longitudinally and is installed at the bottom of the mounting seat 41 so as to be rotatable around its axial direction. The leveling roller 421, the film winding roller 431 and the compacting roller 432 are arranged in sequence at intervals along the transverse direction. The film winding roller 431 is used for winding the protective film 60 to accommodate the protective film 60, and the compacting roller is used to compact the protective film 60 on the surface of the pipe segment.

[0037] Specifically, if Figure 3As shown, the leveling roller 421, the film winding roller 431 and the compacting roller 432 are arranged in sequence from left to right. When the whole roller descends to the right end of the pipe segment surface, the protective film 60 extending from the film winding roller 431 will be adsorbed on the right end of the pipe segment surface. The leveling roller 421, the film winding roller 431 and the compacting roller 432 are driven to move to the left by the walking frame 20. The leveling roller 421 will first level the surface of the pipe segment from right to left, and then the protective film 60 on the film winding roller 431 located on the right side of the leveling roller 421 will be adsorbed on the surface of the pipe segment from right to left. Finally, the compacting roller 432 located on the right side of the film winding roller 431 will compact the protective film 60 adsorbed on the surface of the pipe segment from right to left to the surface of the pipe segment, thereby realizing the coating of the surface of the pipe segment. The design is clever, the structure is simple, and the coating effect is good.

[0038] In one embodiment of the present invention, the film coating assembly 43 further includes a cutting knife 433 , which is movably mounted at the bottom of the mounting base 41 and located on the other side of the compacting roller 432 away from the film winding roller 431 . The cutting knife 433 is used to cut the protective film 60 .

[0039] Specifically, if Figure 3 As shown, a cutting knife 433 is also provided on the right side of the compacting roller 432. By raising and lowering the cutting knife 433, the protective film 60 wound on the film winding roller 431 and the protective film 60 covering the surface of the pipe segment can be separated, which is simple and convenient.

[0040] In an embodiment of the present invention, the leveling roller 421 and the compacting roller 432 are both mounted on the bottom of the mounting base 41 via a first elastic buffer 434 .

[0041] Specifically, since the pipe segment is arc-shaped, the leveling roller 421 and the compacting roller 432 are both installed on the bottom of the mounting seat 41 through the first elastic buffer 434. When the leveling roller 421 and the compacting roller 432 are in contact with the surface of the pipe segment, the elastic buffering effect of the first elastic buffer 434 can enable the leveling roller 421 and the compacting roller 432 to match the shape of the pipe segment, so that the leveling roller 421 and the compacting roller 432 are more closely in contact with the surface of the pipe segment, thereby improving the finishing effect on the surface of the pipe segment.

[0042] In one embodiment of the present invention, the mounting seat 41 is mounted on the bottom of the lifting mechanism 30 via an elastic buffer structure 50 . The elastic buffer structure 50 is used to provide an elastic buffering effect between the lifting mechanism 30 and the mounting seat 41 .

[0043] Specifically, if Figure 2 and Figure 3As shown, an elastic buffer structure 50 is also provided at the bottom of the lifting mechanism 30, and the mounting seat 41 is installed on the elastic buffer structure 50. Through the two-level elastic buffering effect of the elastic buffer structure 50 and the first elastic buffer member 434, the leveling roller 421 and the compacting roller 432 can be better placed in close contact with the surface of the pipe segment, thereby further improving the finishing effect on the surface of the pipe segment.

[0044] In one embodiment of the present invention, the elastic buffer structure 50 includes an elastic buffer seat 51 and a second elastic buffer member 52. The elastic buffer seat 51 extends longitudinally and is installed at the bottom of the lifting mechanism 30 through a plurality of second elastic buffer members 52 arranged at intervals along the longitudinal direction. The two ends of the mounting seat 41 along the longitudinal direction can be hinged to the two ends of the elastic buffer seat 51 along the longitudinal direction so as to rotate around the front and rear directions.

[0045] Specifically, the elastic buffer seat 51 extends in the front-to-back direction. A plurality of second elastic buffer members 52 are spaced apart at intervals along the front-to-back direction at the bottom of the elastic buffer seat 51. The mounting seat 41 is connected to the bottom of the elastic buffer seat 51 via the plurality of second elastic buffer members 51. These plurality of second elastic buffer members 52 provide a more uniform elastic buffering effect between the elastic buffer seat 51 and the lifting mechanism 30, resulting in a better elastic buffering effect. Furthermore, the mounting seat 41 is hingedly connected to the two ends of the elastic buffer seat 51 in the front-to-back direction. The mounting seat 41 can rotate about the extension direction of the hinged seats, thereby driving the leveling assembly 42 and the film covering assembly 43 mounted thereon to better adapt to the curvature of the pipe segment, thereby more closely contacting the surface of the pipe segment.

[0046] In one embodiment of the present invention, the lifting mechanism 30 includes a lifting seat 31 and a plurality of lifting structures 32 connected to the top of the lifting seat 31. The mounting seat 41 is mounted on the bottom of the lifting seat 31. The plurality of lifting structures 32 are arranged at intervals along the longitudinal direction and can be mounted on the walking frame 20 so as to be movable along the longitudinal direction. The plurality of lifting structures 32 are used to jointly drive the lifting seat 31 to rise or fall.

[0047] Specifically, if Figure 1 and Figure 2 As shown, the lifting mechanism 30 includes a plurality of lifting structures 32 spaced apart along the front-to-back direction, which are connected to the walking frame 20 through the plurality of lifting structures 32, and the lifting seat 31 is installed at the bottom of the plurality of lifting structures 32. The plurality of lifting structures 32 jointly drive the lifting seat 31 to rise and fall, and can more smoothly drive the mounting seat 41 installed at the bottom of the lifting seat 31 to rise and fall, thereby improving stability.

[0048] In one embodiment of the present utility model, the lifting structure 32 includes a lifting drive seat 321 and a lifting rod 322. The lifting drive seat 321 is installed on the walking frame 20. The lifting rod 322 extends vertically and is installed on the lifting drive seat 321. The lifting drive seat 321 is used to drive the lifting rod 322 to rise and fall.

[0049] Specifically, if Figure 1 and Figure 2 As shown, the lifting drive seat 321 is installed on the walking frame 20, and the lifting rod 322 is installed on the lifting drive seat 321. The lifting drive seat 321 drives the lifting rod 322 to move up and down, thereby driving the lifting seat 31 to move up and down, and the structure is simple.

[0050] In one embodiment of the present utility model, the walking frame 20 includes two walking seats 21 and two support rods 22. The two walking seats 21 can be installed on the two base frames 11 so as to be movably moved in the horizontal direction. The two support rods 22 are arranged at intervals in the horizontal direction. The two ends of each support rod 22 in the longitudinal direction are respectively installed on the two walking seats 21. The two ends of the lifting seat 31 in the horizontal direction are respectively installed on the two support rods 22. The lifting rod 322 is arranged between the two support rods 22 and can move between the two support rods 22 in the vertical and horizontal directions.

[0051] Specifically, if Figure 1 and Figure 2 As shown, two traveling seats 21 are installed at intervals along the front-to-back direction on the tops of the two frames, and the two traveling seats 21 can drive the two support rods 22 installed thereon to move in the left-right direction, thereby driving the face-collecting structure to move in the left-right direction to process the face of the pipe segment. The structure is simple. The two support rods 22 are arranged at intervals along the left-to-right direction, and a gap extending in the front-to-back direction is formed between the two support rods 22. The two ends of the lifting drive seat 321 in the front-to-back direction can move in the front-to-back direction on the two support rods 22, and the lifting rod 322 installed on the lifting drive seat 321 can move in the front-to-back direction and be raised and lowered in the vertical direction within the gap. The two support rods 22 can provide guidance for the movement of the lifting rod 322 in the front-to-back direction and the lifting and lowering in the vertical direction, thereby allowing the lifting rod 322 to move in the front-to-back direction and be raised and lowered in the vertical direction more reliably and smoothly.
