[0042] Please refer to Figures 2-4 and Figure 7The traction mechanism 5 comprises a winding reel 501 connected to the top of the traveling frame 301, the winding reel 501 is externally wound with a lifting rope 502, the bottom of the lifting rope 502 is sequentially connected with a first lifting hook 503 and a second lifting hook 504, and the first lifting hook 503 and the second lifting hook 504 are respectively connected with one side of the internal maintenance mechanism 6 and the supporting mechanism 7;

[0043] The connection between the lifting hook and the lug is a hanging connection, and the hanging connection can be handled by manual hanging.

[0044] The winding and unwinding of the winding reel 501 should be controlled according to the starting speed of the railcar platform 4, so as to ensure that the internal maintenance mechanism 6 reaches the designed depth after the protective film cover 2 is unfolded outside.

[0045] The internal maintenance mechanism 6 comprises a plurality of movable liquid spraying rings 601, and a corrugated pipe 604 is connected between adjacent liquid spraying rings 601, a plurality of internal liquid spraying nozzles 602 are connected to the outer circumferential side of the liquid spraying ring 601 along the axis at equal intervals, and the liquid spraying ring 601 located at the front side is provided with a first lug 605 connected with the first lifting hook 503, and the plurality of liquid spraying rings 601 are unfolded by moving and stretching through the winding reel 501 to realize internal maintenance.

[0046] The inner fixed ring 603 is connected to the outside of the corrugated pipe 604 through a rod body on the inner side of the liquid spraying ring 601, a positioning hole is formed in the inner fixed ring 603 on one side along the axis at equal intervals, and a positioning rod is connected to the position corresponding to the positioning hole on the other side of the inner fixed ring 603, and adjacent inner fixed rings 603 are positioned through the insertion of the positioning hole and the positioning rod to limit the relative rotation of the inner fixed ring 603.

[0047] Rope sleeves are connected to the outer two sides of the inner fixed ring 603, a rewinding rope 607 is arranged between the rope sleeves, and a rewinder 606 is connected to one side of the fixed ring at the end of the rewinding rope 607, and the unwinding stability of the corrugated pipe 604 and the liquid spraying ring 601 is maintained through the unwinding elastic force of the rewinding rope 607 and the rewinder 606.

[0048] The extension ratio of the corrugated pipe 604 is designed and set according to the length of the box to ensure complete coverage.

[0049] The external maintenance mechanism 8 comprises a plurality of external moving frames 801 arranged in the protective film cover 2, adjacent external moving frames 801 are drivingly connected through transmission hinge rods 803, and a plurality of external liquid spraying nozzles 802 are connected to the inner side of the external moving frame 801, and the external moving frame 801 is arranged in the protective film cover 2.

[0050] The bottom of the external moving frame 801 can be slidingly connected to the track of the railcar platform 4 through corresponding pulleys.

[0051] Specifically: Through the designed internal curing mechanism 6, before the traveling mechanism 3 moves outside the culvert box via the railcar platform 4, it can extend into the culvert box via the hoisting rope 502 and hook up with the internal curing mechanism 6 located in the initial section. The traveling mechanism 3 can then pull the external curing mechanism 8 to unfold via the protective membrane cover 2. At the same time, during travel, the hoisting rope 502 can synchronously pull the first ear seat 605 to drive multiple inner fixing rings 603 to pull the corrugated pipe 604 to unfold. Furthermore, when moving to the tail end of the culvert box, the winch 501 can wind the hoisting rope 502 to fully pull the foremost spray ring 601 to the tail end of the culvert box, thereby enabling the simultaneous unfolding of the external curing mechanism 8 and the internal curing mechanism 6. This facilitates the synchronous steam curing of the culvert box through the retractable internal curing mechanism 6, making subsequent construction easier. The retractable internal curing mechanism 6 and the external curing mechanism 8 can adapt to the steam curing needs of culvert boxes of different lengths, improving curing adaptability.

[0052] Furthermore, through the designed rewinder 606 and rewind rope 607, the rewind rope 607 can pull the rewind spring of the rewinder 606 to tighten when it is pulled. When the traction mechanism 5 loosens the first ear seat 605, the rewinder 606 can rewind through the elastic force of the rewind spring to drive the spray ring 601 to reset, which is convenient.

[0053] The traction and release of the hoisting rope 502 is controlled manually or by a robotic arm.

[0054] The supporting mechanism 7 includes a liquid-receiving membrane 701. One end of the liquid-receiving membrane 701 is wound with a winding roller 702, which is connected to the initial end of the protective membrane cover 2. The other end of the liquid-receiving membrane 701 is connected to a moving plate 703. A second ear piece 704 is connected to one side of the moving plate 703. The second ear piece 704 is hooked to a second hook 504. The second hook 504 pulls the second ear piece 704 and the moving plate 703 to pull the liquid-receiving membrane 701 to unfold.

[0055] Specifically: Through the designed support mechanism 7, when the spray ring 601 sprays liquid on the outer periphery of the culvert box for steam curing, after the steam is sprayed out, the second hook 504 can pull the second ear 704 to open the liquid receiving film 701 simultaneously. After the liquid receiving film 701 is unfolded, it can receive the water droplets condensed by the steam, avoiding the accumulation of condensate at the bottom of the culvert box, which would cause excessive water in the bottom area of ​​the culvert box and affect the drying effect. This is conducive to improving the curing effect. After the curing is completed, the winding roller 702 can reverse the direction to rewind the liquid receiving film 701, thereby improving the treatment effect.

[0056] In use, the steam generator 1 heats water by transporting it from the storage tank to the steam generator 1. The water temperature is controlled by the sensor, and the water is heated from a liquid state to a steam state. Finally, the steam is transported to the inside and outside of the box culvert prefabrication through the air pressure device for component curing.

[0057] Before the traveling mechanism 3 moves outside the culvert box via the railcar platform 4, it extends into the culvert box via the hoisting rope 502 and is connected to the inner maintenance mechanism 6 located in the initial section. The traveling mechanism 3 pulls the outer maintenance mechanism 8 to unfold via the protective membrane cover 2. At the same time, during the travel, the hoisting rope 502 synchronously pulls the first ear seat 605 to drive multiple inner fixing rings 603 to pull the corrugated pipe 604 to unfold. When the culvert box is at the tail end during the movement, the trolley 501 winds the hoisting rope 502 to fully pull the foremost spray ring 601 to move to the tail end of the culvert box, and the outer maintenance mechanism 8 and the inner maintenance mechanism 6 are unfolded simultaneously.

[0058] When the traveling mechanism 3 moves to the end of the culvert, it pulls the moving rod 303 downward through the straight modules on both sides. The moving rod 303 moves and pulls the roller shutter 302. The roller shutter 302 pulls the opening on the front side of the closed protective film cover 2. When the spray ring 601 sprays liquid on the outer periphery to steam cure the culvert, after the steam is sprayed out, the second hook 504 pulls the second ear 704 to open the liquid receiving membrane 701 at the same time. After the liquid receiving membrane 701 unfolds, it receives the water droplets condensed by the steam, preventing the condensate from accumulating at the bottom of the culvert.
