Description

Technical Field

[0001] This utility model relates to the field of concrete curing technology, and more specifically, to a concrete curing device. Background Technology

[0002] If concrete is poured in hot and dry weather and not cured in time, the water in the concrete will evaporate too quickly, causing dehydration. This will prevent the cement particles that have formed a gel from fully hydrating and transforming into stable crystals, resulting in insufficient bonding strength. Consequently, flaking or powdering will occur on the concrete surface. Therefore, a concrete curing device is needed to facilitate timely concrete curing. Concrete curing involves artificially creating certain humidity and temperature conditions to allow freshly poured concrete to harden normally or accelerate its strength development.

[0003] A search revealed that Chinese utility model patent application number CN202420329319.8 discloses a concrete curing device, including a base and a winding assembly. The lower surface of the base is equipped with casters, and the winding assembly is located on the front side of the upper surface of the base. The winding assembly includes a support frame, a servo motor, a winding rod, a limit plate, and a limit fixing groove. The support frame is located on the front side of the upper surface of the base, and a servo motor is installed at the upper end of the left side surface of the support frame. The output end of the servo motor is connected to the winding rod through a coupling, and a limit plate is installed on the surface of the winding rod. The limit plates are symmetrically arranged at both ends of the winding rod.

[0004] When in use, a protective film is laid out to retain moisture while water is being sprayed. However, because the protective film is relatively light, it is easily blown away by the wind after it is laid out. It is not convenient to cover the protective film, which reduces its practicality. In addition, the distance between the two limit plates is fixed, and the length of the winding rod installed between the two limit plates is also fixed, which makes it inconvenient to install and fix winding rods of different lengths.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, the present invention provides a concrete curing device with the following advantages:

[0018] 1. Multiple adjusting seats slide inside the channel, and multiple sand drop pipes adjust to the corresponding positions according to the width of the protective membrane, so that sand can be pressed onto the protective membrane of different widths. During the laying of the protective membrane, the sand inside the box falls onto the protective membrane laid on the concrete through the hose and sand drop pipe.

[0030] Please see Figures 1-5A concrete curing device includes a base 1 with multiple casters 31 mounted on its bottom for easy movement. A water tank 2 is mounted on the top of the base 1, and a water pump 3 is connected to the side of the water tank 2. A spray pipe 4 is connected to the bottom of the base 1 and is connected to the output end of the water pump 3. Multiple spray nozzles 5 are connected to the bottom of the spray pipe 4. A winding rod 6 is connected to the top of the base 1 via a connecting mechanism. A film-laying groove 7 is provided on the base 1, and two guide rollers 30 are rotatably connected inside the film-laying groove 7 to guide the protective film, preventing it from contacting the base 1 and being damaged. The top of the base 1 is connected to two support plates 8. The box body 9 and the base 1 are fixedly connected to the side of the fixed seat 10. The fixed seat 10 is provided with a through groove 11. Multiple adjusting seats 12 are slidably arranged inside the through groove 11. Each of the multiple adjusting seats 12 is equipped with a sand drop pipe 13. Each of the multiple sand drop pipes 13 is equipped with a valve 29 to facilitate the control of the opening and closing of the sand drop pipe 13. The top of each of the multiple sand drop pipes 13 is connected to a flexible hose 14. Each of the multiple flexible hoses 14 is connected to the bottom inside the box body 9. A square column 15 is fixedly connected inside the through groove 11. Each of the multiple adjusting seats 12 is slidably engaged with the square column 15. Each of the multiple adjusting seats 12 is threadedly connected with a fixing screw 32 that engages with the square column 15 to facilitate the fixing of the adjusting seat 12.

[0031] Specifically, multiple adjusting seats 12 slide inside the through groove 11, and are adjusted to the corresponding positions according to the width of the protective membrane via multiple sand drop pipes 13, so that sand can be pressed onto the protective membrane of different widths. During the laying of the protective membrane, the sand inside the box 9 falls onto the protective membrane laid on the concrete through the hose 14 and the sand drop pipe 13. The falling sand presses the protective membrane onto the concrete, preventing it from being blown away by the wind, ensuring the protective and moisturizing effect of the protective membrane on the concrete, and improving its practicality.

[0032] Please see Figures 2-4The connecting mechanism includes a bidirectional screw 16, a first motor 17, and a second motor 18. A groove 19 is provided at the top of the base 1, and the bidirectional screw 16 is located inside the groove 19, rotatably connected to the base 1. Two sliding blocks 20 are symmetrically threaded onto the outside of the bidirectional screw 16, both sliding blocks 20 slidingly engaging with the groove 19. A vertical seat 21 is fixedly connected to the top of each of the two sliding blocks 20, and a first rotating shaft 22 is rotatably connected to each of the two vertical seats 21. The two first rotating shafts 22 are fixed at opposite ends. A regular hexagonal column 23 is fixedly connected to the base 1. Both ends of the winding rod 6 are provided with regular hexagonal slots 24. The first motor 17 is installed on the side of the base 1. The output end of the first motor 17 is fixedly connected to the side of the bidirectional screw 16. The second motor 18 is installed on the vertical seat 21. The second motor 18 is fixedly connected to the corresponding first rotating shaft 22. Two fixed rods 25 are fixedly connected inside the slide groove 19. Both fixed rods 25 slide in cooperation with the two slide blocks 20 to ensure that the slide blocks 20 slide stably inside the slide groove 19.

[0033] Specifically, the first motor 17 drives the bidirectional screw 16 to rotate, and the rotation of the bidirectional screw 16 causes the two slides 20 to move in opposite directions. The two slides 20 drive the two vertical seats 21 and the two first rotating shafts 22 to move. Adjusting the distance between the two first rotating shafts 22 facilitates the replacement of the winding rod 6 and the installation and fixing of winding rods 6 of different lengths.

[0034] Please see Figure 5 The bottom of the box 9 is rotatably connected to a second rotating shaft 26. Multiple stirring plates 27 are fixedly connected to the outside of the second rotating shaft 26. A third motor 28 is installed on the side of the box 9. The output end of the third motor 28 is fixedly connected to the side of the second rotating shaft 26, which facilitates stirring of the sand inside the box 9 and avoids sand blockage.

[0035] Specifically, the third motor 28 drives the second rotating shaft 26 and multiple stirring plates 27 to rotate. The multiple stirring plates 27 stir the sand around the multiple hoses 14 inside the box 9, so that the sand inside the box 9 can flow through the hoses 14 to the inside of the sand drop pipe 13. This prevents the sand inside the box 9 from accumulating around the hoses 14 and causing blockage, ensuring the continuity of the sand falling on the protective film and ensuring the effect of covering the protective film.

[0036] In summary, when using the overall equipment:

[0037] During the process of protecting the concrete, the device moves on the concrete that needs to be protected. In this process, the water inside the water tank 2 is pumped out by the water pump 3 and delivered to the water spray pipe 4 and multiple water spray nozzles 5. The water is evenly sprayed onto the concrete through the multiple water spray nozzles 5. Then the protective membrane is laid on the concrete. The sand inside the tank 9 flows into the inside of multiple sand drop pipes 13 through multiple hoses 14. The sand falls onto the laid protective membrane through the sand drop pipes 13, pressing the protective membrane onto the concrete.
