[0001] This utility model relates to the field of curing device technology, specifically a curing device for precast concrete components. Background Technology
[0002] Precast concrete components are concrete structures pre-cast in a factory or on-site, cured, and then transported to the construction site for installation. Due to their standardization, efficiency, and quality control, they are widely used in construction, bridges, and municipal engineering. After production, precast concrete components require curing, which involves spraying water to cool them. However, existing curing devices cannot effectively cure precast components of varying sizes, especially taller ones, and the height of the equipment makes water replenishment inconvenient. Therefore, improvements to existing technology are necessary. Utility Model Content

[0021] Please see Figure 1 , Figure 3 , Figure 4 A reinforcing frame 6 is fixedly connected to the outside of the spray frame 5. The reinforcing frame 6 is fixedly connected to the frame 1. The reinforcing frame 6 can increase the stability of the spray frame 5. The output shaft of the motor 11 is fixedly connected to the positive and negative screws 10. The support rod 13 is hinged to the support bar 8. The motor 11 can drive the positive and negative screws 10 to move. A guide plate 14 is slidably connected to the lower outer side of the guide rod 15. The guide plate 14 is fixedly connected to the expansion box 7. The expansion box 7 is in sliding contact with the support bar 8. The guide plate 14 can guide the movement of the guide rod 15. The support seat 17 is connected to the positive and negative screws 10 through a bearing. A slider 16 is fixedly connected to the upper end of the threaded sleeve 12. The slider 16 is slidably connected to the expansion box 7. The slider 16 can guide the movement of the threaded sleeve 12.
[0022] Please see Figure 1, Figure 2 The one-way water filling mechanism 4 includes a connecting cover 41. The lower end of the water filling pipe 3 is fixedly connected to the connecting cover 41. The connecting cover 41 is fixedly connected to the inside of the connecting cover 41. The connecting pin 43 is slidably connected to the inside of the connecting pin 42. The upper end of the connecting pin 43 is fixedly connected to a sealing plug 44. The outer side of the sealing plug 44 is in sliding contact with a sealing ring 45. A spring 46 is provided on the outer side of the connecting pin 43. The sealing plug 44 can seal the connecting cover 41 through the sealing ring 45.

[0023] The specific implementation process of this utility model is as follows: When in use, the water pump pipe is inserted into the inside of the connecting cover 41, and then the water pump is started. When the water pressure generated by the water pump pushes the sealing plug 44 more than the elastic force of the spring 46, the sealing plug 44 moves and compresses the spring 46 through the connecting pin 43. When the sealing plug 44 is separated from the sealing ring 45, the water flow can fill the water tank 2 through the connecting cover 41 and the water filling pipe 3. After the water filling is completed, the water pump is stopped, and then the water pump connecting pipe is pulled out from the inside of the connecting cover 41. When stopped, the spring 46 returns to its original position. The spring 46 can drive the sealing plug 44 to slide into the inside of the sealing ring 45 through its elastic force, thus completing the sealing of the sealing ring 45, which makes it more convenient to add water.
[0024] When the spraying height needs to be adjusted, the motor 11 is started. The motor 11 drives the positive and negative screws 10 to rotate. During the rotation, the positive and negative screws 10 can drive the threaded sleeve 12 to support it through the threaded engagement with the threaded sleeve 12. During the movement, the threaded sleeve 12 can support the extension box 7 through the hinge between it and the support bar 8. During the upward movement of the extension box 7, the spraying height of the spray frame 5 can be adjusted. After the adjustment is completed, the submersible pump installed inside the water tank 2 supplies water to the spray frame 5, and the precast components can be cured through the spray frame 5.
