[0002] Concrete precast piles are structural members prefabricated in factories and installed on-site. They are widely used in building foundations and civil engineering. Since they are produced in factories, their quality and dimensions can be strictly controlled, improving construction efficiency and safety. However, the natural curing time of concrete is relatively long. Using a steam curing device can accelerate the hardening process of concrete, increase its strength and durability in a short time, significantly shorten the production cycle and construction period, and ensure the quality stability and reliability of precast piles. Therefore, the steam curing device is crucial in the production of precast piles.

[0003] In traditional steam curing devices for concrete precast piles, steam is generated by a steam generator and transported to the curing chamber, where it is evenly sprayed on the surface of the precast piles through a steam distribution system. The temperature and humidity in the curing chamber are monitored by sensors and adjusted through an automatic control system to maintain within a preset range. Condensate is discharged in a timely manner through a drainage system to ensure the stability of the curing environment. The whole process is completed within several hours to one day, greatly accelerating the hardening and strength improvement of concrete and ensuring that the precast piles meet the expected quality standards in a short time.

[0004] In traditional steam curing devices for concrete precast piles, due to the sub-optimal design of the steam distribution system and the difficulty in driving the precast piles, it is often difficult to achieve uniform steam curing of the precast piles, resulting in differences in the curing effects of different parts of the concrete precast piles and affecting the overall strength and durability.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] Referring to Figure 1 - Figure 3 , an embodiment provided by the present invention: a steam curing device for precast concrete piles, including a curing chamber 1, a steam generator 2 is fixedly connected to the top of the curing chamber 1, a flow splitting component is arranged inside the steam generator 2, and the flow splitting component is used to evenly discharge the mist into the curing chamber 1. A motor 5 is fixedly connected inside the curing chamber 1, a toothed cam 6 is fixedly connected to the output end of the motor 5, a toothed transmission belt 7 is arranged inside the curing chamber 1, and the toothed cam 6 meshes with the toothed transmission belt 7. A rotating rod 9 is rotatably connected inside the curing chamber 1, toothed cams 8 are fixedly connected to both ends of the rotating rod 9, and the toothed cams 8 mesh with the toothed transmission belt 7. A rotating roller 10 is fixedly connected to the outer wall of the rotating rod 9, an anti-slip pad 11 is fixedly connected to the outer wall of the rotating roller 10, and the rotating roller 10 and the anti-slip pad 11 are both rotatably connected inside the curing chamber 1. The flow splitting component includes a flow splitting pipe 3, one end of the flow splitting pipe 3 is fixedly connected inside the steam generator 2, spray nozzles 4 are fixedly connected to the outer wall of the flow splitting pipe 3, and the outer wall of the flow splitting pipe 3 is fixedly connected to the inner wall of the curing chamber 1;

[0025] Specifically, the steam generator 2 generates atomized gas, and then the mist is evenly discharged into the curing chamber 1 through the flow splitting pipe 3 and the spray nozzles 4. Then, the motor 5 is started, and the toothed cam 6 is driven to rotate by the output end of the motor 5. Due to the meshing relationship between the toothed cam 6, the toothed transmission belt 7, and the toothed cam 8, the toothed transmission belt 7 drives the toothed cam 8 to rotate, thereby driving the rotating rods 9 on both sides to rotate. Furthermore, a plurality of rotating rollers 10 are driven to rotate through the rotating rods 9. Finally, the anti-slip pad 11 is driven to rotate by the rotating roller 10 to drive the precast pile, so as to drive the precast pile to rotate inside the curing chamber 1, and the outer wall of the precast pile is evenly subjected to atomization treatment.

[0026] Referring to Figure 1 and Figure 4, a connecting plate 12 is fixedly connected to the outer wall of the curing chamber 1. A fixed semi-ring 13 is fixedly connected to the outer wall of the curing chamber 1. One end of the fixed semi-ring 13 is rotatably connected to a movable semi-ring 14. The other end of the fixed semi-ring 13 is rotatably connected to a screw rod 15. The outer wall of the screw rod 15 is slidably connected inside the movable semi-ring 14. A moving sleeve 16 is threadedly connected to the outer wall of the screw rod 15. A fixed ring 17 is fixedly connected to the outer wall of the moving sleeve 16. The lower surface of the moving sleeve 16 is attached to the outer wall of the movable semi-ring 14. A sealing ring 18 is fixedly connected to the inner wall of the fixed semi-ring 13. One side of the outer wall of the sealing ring 18 is attached to the outer wall of the connecting plate 12. The other side of the outer wall of the sealing ring 18 is attached to a baffle 19. The baffle 19 is arranged between the fixed semi-ring 13 and the movable semi-ring 14;

[0027] Specifically, first drive the fixed ring 17, which can drive the moving sleeve 16 to rotate on the outer wall of the screw rod 15, so that the moving sleeve 16 moves up and down on the outer wall of the screw rod 15. Next, pull the screw rod 15 to rotate at one end of the fixed semi-ring 13. When the screw rod 15 no longer contacts the movable semi-ring 14, the movable semi-ring 14 can be easily pulled to rotate at the other end of the fixed semi-ring 13, so that the baffle 19 is no longer restricted. At this time, the baffle 19 is removed, and then the precast pile can be placed into the curing chamber 1. Then, the baffle 19 is put back in place, and then the movable semi-ring 14 and the screw rod 15 are rotated in the reverse direction, and the baffle 19 can be fixed again. The coating can also be sealed through the sealing ring 18, achieving the effects of separate feeding and sealing.

[0028] Working principle: When the steam curing device for concrete precast piles is needed, first operate the fixed ring 17 to make the moving sleeve 16 rotate along the outer wall of the screw rod 15 and move up and down. Then, rotate the screw rod 15 to disengage it from the movable semi-ring 14, facilitating the rotation of the movable semi-ring 14 at the other end of the fixed semi-ring 13 to release the restriction of the baffle 19. At this time, the baffle 19 can be removed, and the precast pile is placed into the curing chamber 1. After the baffle 19 is repositioned, rotate the movable semi-ring 14 and the screw rod 15 in the reverse direction to re-fix the baffle 19 and achieve sealing through the sealing ring 18, realizing the functions of feeding and sealing;

[0029] In addition, the steam generator 2 generates atomized gas, which is evenly distributed in the curing chamber 1 through the shunt pipe 3 and the nozzle 4. Start the motor 5, and its output end drives the toothed cam one 6 to rotate. The meshing relationship between the toothed cam one 6, the toothed transmission belt 7 and the toothed cam two 8 makes the toothed transmission belt 7 drive the toothed cam two 8 to rotate, thereby driving the rotating rod 9 and multiple rotating rollers 10 to rotate. The rotation of the rotating rollers 10 pushes the precast pile to rotate in the curing chamber 1 through the anti-slip pads 11, ensuring that the outer wall of the precast pile is evenly atomized.

[0030] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
