[0002] With the rapid development of subway transportation in major cities, shield construction technology with low cost and high degree of mechanization has been applied more and more widely. Shield segments are the main assembly components of shield construction and the outermost barrier of the tunnel. They are responsible for resisting soil pressure, groundwater pressure and some special loads. The quality of shield segments is directly related to the overall quality and safety of the tunnel, affecting the waterproof performance and durability of the tunnel, and plays a key role in controlling the quality of the tunnel, maintaining the linear shape of the tunnel and ensuring the service life of the subway tunnel.

In the pipe segment mold assembly step, the inner and outer periphery and bottom concrete residues of the pipe segment mold will be cleaned first, and then the pipe segment mold will be assembled, and the release agent will be evenly coated on the inner surface of the pipe segment mold.

[0004] The release agent is usually applied by professional spraying equipment to evenly spray the release agent onto the mold surface. However, during spraying, the release agent tends to accumulate at the bottom of the segment mold, and the accumulated liquid needs to be removed with cotton yarn, rags, etc. after spraying. However, the inner surface of the segment mold has edges, corners and other complex shapes, making the removal of accumulated liquid more complicated. Summary of the invention

DETAILED DESCRIPTION

[0028] The following is combined with Figure 1-5 This application is described in further detail.

[0029] The prefabricated segment processing system provided in the embodiment of the present application is as follows: Figure 1 and Figure 2 As shown, it includes a forming mold 1, a mold transportation line 2, a turning mechanism 3, a mold pretreatment module 4 and a pouring module 5. The forming mold 1 includes a mold frame 11 and a mold body 12. The mold body 12 has a pouring cavity 121 with an opening at one end, which is used to contain concrete and form a pipe segment; and a pair of opposite inner walls in the pouring cavity 121 are fixed with a plurality of hole-forming protruding rods 122, so that reserved holes can be formed on the outer wall of the pipe segment obtained after pouring and forming. The bottom of the mold body 12 is fixed on the mold frame 11, and moving platforms 13 are fixed at both ends of the mold frame 11. The moving platform 13 can drive the mold frame 11 to move, thereby realizing the transfer of the forming mold 1 between different stations.

[0030] like Figure 1As shown, the mold transport line 2 includes a preparation track 21, a processing track 22, a processing track 23 and a temporary storage track 24 arranged in the same straight line. A plurality of molding molds 1 are arranged at intervals on the preparation track 21, and the opening of the casting cavity 121 of the molding mold 1 is arranged downward. The flip mechanism 3 is located between the processing track 22 and the processing track 23, and the mold pretreatment module 4 is arranged below the processing track 22. The mold pretreatment module 4 includes a spraying component 41, a cleaning component 42 and a dryer 43. The cleaning component 42 is arranged close to the preparation track 21, the spraying component 41 is arranged close to the flip mechanism 3, and the dryer 43 is located between the spraying component 41 and the cleaning component 42.

[0031] like Figure 1 As shown, the spray assembly 41 specifically includes a spray mesh pipe 412 and a plurality of spray heads 411 connected to the spray mesh pipe 412, and the spray heads 411 are arranged toward the processing track 22. The cleaning assembly includes a wastewater collection tank body 422 and a plurality of cleaning spray guns 421 fixed at the opening of the wastewater collection tank body 422, and the cleaning spray guns 421 are also arranged toward the processing track 22. Starting the cleaning spray guns 421 can clean the casting cavity 121 of the molding mold 1 to remove the residue and dirt in the casting cavity 121. The dryer 43 is used to dry the cleaned molding mold 1 to prepare for the subsequent release agent spraying. In this embodiment, the dryer 43 specifically adopts an infrared drying device. When the molding mold 1 slides along the processing track 22 to the spray assembly 41 after drying, the release agent is introduced into the spray mesh pipe 412, and the plurality of spray heads 411 can directly spray the release agent on the inside of the molding mold 1. Since the opening of the casting cavity 121 of the molding mold 1 faces downward, the excess release agent will automatically drip down under the action of gravity, without the need for an additional wiping step, thereby simplifying the processing process.

[0032] like Figure 1 and Figure 3As shown, the flipping mechanism 3 specifically includes a flipping device 31 and a lifting device 32. The lifting device 32 includes a lifting frame 321, a lifting rail 322 fixed on the lifting frame 321, and a lifting sling slidably arranged on the lifting rail 322. The lifting rail 322 is parallel to the processing track 22, one end of the lifting rail 322 extends above the processing track 22, and the other end extends above the processing track 23. The flipping device 31 is located below the lifting rail 322. The lifting device 323 includes a walking mechanism 3231, a lifting mechanism 3232 fixed below the walking mechanism 3231, and a lifting arm 3233 fixed at the lifting end of the lifting mechanism 3232; the walking mechanism 3231 is slidably connected to the lifting rail 322, and the lifting mechanism 3232 is used to drive the lifting arm 3233 to rise and fall. When the forming mold 1 slides to one end of the processing track 22 close to the turning mechanism 3, the lifting mechanism 3232 drives the arm 3233 to descend, and the forming mold 1 is connected to the arm 3233 through the lifting device at one end of the arm 3233, so that the lifting device can lift the forming mold 1 to the turning device 31. In this embodiment, the walking mechanism 3231 is specifically configured as an electric walking wheel, and the lifting mechanism 3232 is specifically configured as an electric hoist.

[0033] like Figure 1 and Figure 3 As shown, the flip device 31 includes a mounting support 311 and two flip frames 312 arranged at intervals on the mounting support 311; one end of the flip frame 312 is hinged on the mounting support 311, and one side of each flip frame 312 is connected to a corresponding driving member 313. In this embodiment, the driving member 313 is specifically configured as a hydraulic cylinder; one end of the hydraulic cylinder is hinged on the mounting support 311, and one end of the telescopic rod of the hydraulic cylinder is hinged to the flip frame 312. Start the hydraulic cylinder to drive the flip frame 312 to rotate. When in use, one flip frame 312 close to the processing track 22 is rotated to a horizontal state, and the other flip frame 312 is rotated to a vertical state; after the crane hoists the forming mold 1 onto the flip frame 312 in a horizontal state, the other flip frame 312 is rotated to abut against the forming hanger; then the two flip frames 312 are driven by the hydraulic rod to rotate simultaneously in the direction close to the processing track 23, until the forming mold 1 is driven to move to a horizontal state, so as to achieve a 180° flip of the forming mold 1. Subsequently, the flipped forming mold 1 is hoisted onto the processing track 23 by the jack 323 , and the pouring cavity 121 of the forming mold 1 on the processing track 23 opens upward, which is convenient for subsequent pouring processing.

[0034] like Figure 4As shown, the casting module 5 is arranged on the processing track 23, and the casting module 5 includes a feeding device 51 and a lifting device 52. The lifting device 52 includes a truss 521 and a plurality of telescopic push rods 522 fixed on the truss 521. The telescopic push rods are located above the processing track 23, and a cover plate 53 is fixed to the telescopic end of the telescopic push rods 522. The shape of the cover plate 53 is adapted to the opening of the casting cavity 121, and a pouring port is opened in the center of the cover plate 53. A plurality of guide plates 531 are also arranged on the side wall of the cover plate 53 close to the lifting device 52. The guide plate 531 is fixed to the peripheral side of the pouring port, and one end of the guide plate 531 is tilted upward in a direction away from the cover plate 53. In this embodiment, two guide plates 531 are arranged relatively, and the telescopic push rods 522 are specifically arranged as lifting cylinders, and four telescopic push rods 522 are evenly distributed on the cover plate 53.

[0035] like Figure 2 and Figure 4 As shown, the feeding device 51 includes a conveying guide rail 512 and an upper hopper 511 arranged on a truss 521, and a lower hopper 513 slidably connected to the conveying guide rail 512. The upper hopper 511 is located above the pouring port, and the lower ends of the upper hopper 511 and the lower hopper 513 are both connected to a discharge pipe that can be opened and closed. The lower hopper 513 receives concrete in advance, slides to the top of the upper hopper 511 through the conveying guide rail 512, and discharges the concrete into the upper hopper 511 for storage. When the molding mold 1 moves to the bottom of the upper hopper 511, the telescopic push rod 522 drives the cover plate 53 to descend, covering the opening of the casting cavity 121; then the concrete is discharged into the casting cavity 121 through the pouring port through the upper hopper 511.

[0036] like Figure 1 As shown, a curing kiln 7 is also provided on the processing track 23. The curing kiln 7 is located on the side of the feeding device 51 away from the turning mechanism 3 and is used to cure the poured concrete to ensure the strength and durability of the pipe segment.

[0037] In order to facilitate the demoulding of the cured pipe segments, Figure 1 As shown, a segment demoulding module 6 is further provided between the flipping mechanism 3 and the mold pretreatment module 4. When the mold with the segment moves to the flipping mechanism 3 and is flipped 180 degrees again, and is transported to the treatment track 22, the forming mold 1 is first demoulded, and then the segment is separated from the forming mold 1 through the segment demoulding module 6.

[0038] like Figure 5As shown, the segment demoulding module 6 includes a locking member 61 and a lifting platform 62, and the moving platform 13 includes a pulley 131, and the pulley 131 is made of ferromagnetic material. Accordingly, the locking member 61 is specifically configured as an electromagnetic locking block fixed on the processing track 22, which is used to generate magnetism by conducting electricity to the electromagnetic locking block, and adsorb and lock the pulley 131, thereby fixing the forming mold 1. The positioning and locking of the forming mold 1 are conveniently achieved, and the safety and stability during the demoulding process are improved. The lifting platform 62 includes a lifting mechanism 621 and a material support suction cup 622 connected to the lifting end of the lifting mechanism 621; the lifting mechanism 621 is specifically configured as a hydraulic lifting platform, and the material support suction cup 622 is connected to a vacuum generator (not shown in the figure), so that a negative pressure environment can be formed on one side of the material support suction cup 622 to adsorb the segment. The lifting mechanism 621 is slidably arranged below the processing track 22, and the sliding direction of the lifting mechanism 621 is arranged perpendicular to the processing track 22.

[0039] When the forming mold 1 with the pipe segment moves to the pipe segment demolding module 6, the electromagnetic lock block is turned on to lock the moving platform 13 in the forming mold 1; the lifting mechanism 621 rises, driving the supporting suction cup 622 to move to abut against the pipe segment in the forming mold 1; then the forming mold 1 is demolded, so that the supporting suction cup 622 sucks the pipe segment and drives the pipe segment down, so that the pipe segment is separated from the forming mold 1 under the action of the supporting suction cup 622 and gravity; and the lifting mechanism 621 drives the pipe segment to move away from the bottom of the processing track 22. In this embodiment, the size of the supporting suction cup 622 is smaller than the pipe segment. The pipe segment can be removed from the supporting suction cup 622 by a forklift or other transfer equipment and transported to the pipe segment storage area. The lifting mechanism 621 drives the supporting suction cup 622 to move back to its original position, which is convenient for demolding the pipe segment in the next forming mold 1.

[0040] The implementation principle of a prefabricated pipe segment processing system in the embodiment of the present application is as follows: multiple forming molds 1 are placed on the preparation track 21 at intervals, and the opening of the casting cavity 121 of the forming mold 1 is set downward; the moving table 13 in the forming mold 1 is started to move the forming mold 1; when the forming mold 1 slides on the processing track 22, it is cleaned, dried and sprayed with a release agent in sequence; after the forming mold 1 slides to the end of the processing track 22, the flipping mechanism 3 flips the forming mold 1 180°, and transfers the flipped forming mold 1 to the processing track 23. When the forming mold 1 slides on the processing track 23, the pipe segment casting and pipe segment curing are carried out in sequence, and the forming mold 1 that has completed the pipe segment curing continues to slide to the temporary storage track 24. After all the forming molds 1 in the system have completed the pipe segment curing, the sliding direction of the moving table 13 in each forming mold 1 is changed. When the forming mold 1 with the pipe segment moves to the flipping mechanism 3, the flipping mechanism 3 continues to flip the forming mold 1 180°, and transports the flipped forming mold 1 to the processing track 22. After the forming mold 1 is locked by the electromagnetic locking block, the material supporting suction cup 622 is moved to abut against the pipe segment in the forming mold 1, and then the forming mold 1 is demolded; the pipe segment is moved away from the processing track 22 by the lifting support platform 62.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
