Description

Technical Field

[0001] This utility model relates to the field of concrete curing technology, and in particular to a spraying device for concrete curing. Background Technology

[0002] Concrete is a general term for composite materials made by mixing gel materials, aggregates and water in appropriate proportions and then hardening them over a certain period of time. When concrete has initially set but before it has fully set, it can be sprayed with water for curing when you press it lightly with your finger and it leaves no fingerprint or leaves a slight mark but is no longer sticky. This state usually means that the concrete has initially set. According to the "Specification for Construction of Hydraulic Concrete" (DL / T 5144-2015), "Concrete should be moistened 3 hours after initial setting" and "Concrete curing should be continuous, and the concrete surface should be kept moist during the curing period." Hydraulic structures' concrete components are characterized by large cross-sectional dimensions. In particular, the vertical curing of large components such as piers and walls is much more difficult than horizontal curing. The main reason is the difficulty in retaining moisture. Furthermore, the airflow speed in the air is faster than that on the ground, resulting in a more severe drying effect. Excessive moisture loss from the concrete surface easily leads to drying shrinkage, causing surface cracks. Moreover, in high-temperature or windy weather, high temperatures and strong winds can further exacerbate the problem. The ground accelerates the evaporation of moisture from the concrete surface. If moisture is not replenished in time, the concrete will lose water rapidly, leading to plastic shrinkage cracks. Therefore, after the concrete is poured and initially set, it can be sprayed for curing. However, the equipment used for spraying concrete for curing can generally only spray concrete poured on the ground. For vertical concrete surfaces, such as walls, workers need to manually spray with water hoses. However, manually spraying vertical concrete surfaces such as walls results in uneven spraying, poor spraying effect, and is time-consuming and labor-intensive, reducing the quality of the concrete after final setting. Utility Model Content

[0003] This utility model discloses a spraying device for concrete curing, which solves the problem of uneven spraying and poor spraying effect caused by manually spraying vertical concrete surfaces such as walls.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A concrete curing spraying device includes a mobile vehicle with a water tank fixed on it. The mobile vehicle has a liftable movable plate, and a water pipe is located on one side of the movable plate. The water pipe has a first spray pipe and a second spray pipe for spraying water onto a wall and the ground, respectively. The first and second spray pipes are each connected to a fixed pipe that is also connected to the water pipe, and a valve is installed on the fixed pipe. A screw threaded to the movable plate is located above the mobile vehicle, and a first motor for driving the screw to rotate is fixed on the mobile vehicle. A water pump is installed on the water tank to transport water from the tank to the water pipe.

[0005] Compared with the prior art, the present invention has the following beneficial effects: When spraying and curing concrete poured on the ground, the valve on the fixed pipe connected to the second spray pipe is opened, and the water pump is started to deliver water into the water pipe. Then, the water is discharged through the second spray pipe, and as the mobile vehicle moves, the concrete ground can be evenly sprayed and cured. When spraying and curing vertical concrete walls, the valve on the fixed pipe connected to the first spray pipe is opened, allowing water to be discharged through the spray pipe and cured on the concrete wall. At the same time, the first motor is started to rotate the screw, and the moving plate can move upward. The first spray pipe moves along with it, and the wall can be evenly sprayed and cured from bottom to top. This utility model can evenly spray and cure concrete ground and vertical concrete walls separately, improving the spraying effect and efficiency, and ensuring the quality of the concrete after final setting.

[0008] The specific content of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0009] like Figure 1 , Figure 2 and Figure 4As shown, this utility model provides a spraying device for concrete curing, including a mobile vehicle 1, a water tank 2 fixed on the mobile vehicle 1, a liftable movable plate 3 on the mobile vehicle 1, a water pipe 4 on one side of the movable plate 3, a first spray pipe 41 and a second spray pipe 42 respectively for spraying onto the wall and the ground on the water pipe 4, and a fixed pipe 5 connected to the first spray pipe 41 and the second spray pipe 42 respectively, and a valve is installed on the fixed pipe 5; a screw 7 threadedly connected to the movable plate 3 is provided above the mobile vehicle 1, and a first motor 71 for driving the screw 7 to rotate is fixed on the mobile vehicle 1; a water pump 21 for transporting water in the water tank 2 to the water pipe 4 is installed on the water tank 2. A first connecting frame 72 is fixed on the shaft of the first motor 71. A rotating rod 73, which is fixed to the lead screw 7, is rotatably connected to the inner side of the first connecting frame 72. A second connecting frame 8 is fixed on the moving vehicle 1. A limiting rod 81, which passes through the moving plate 3 and is slidably connected to the inner side of the second connecting frame 8, is rotatably connected to the inner side of the moving plate 3. A fixing plate 9 is fixed to the inner side of both the first connecting frame 72 and the second connecting frame 8. A screw 91 is threadedly connected to the fixing plate 9. The bottom of the lead screw 7 and the limiting rod 81 are both provided with screw holes that are compatible with the screw 91. The first spray pipe 41 is located on the left side of the water pipe 4 (the side of the water pipe 4 away from the water tank 2), and the second spray pipe 42 is located below the water pipe 4. When it is necessary to spray the concrete floor, open the valve on the fixed pipe 5 connected to the second spray pipe 42 (the valve is not shown in the figure; both valves on the fixed pipe 5 are solenoid valves), and then start the water pump 21. The water pump 21 is fixed on the mobile vehicle 1 and connected to the water tank 2, and the water pump 21's suction end passes through the water tank 2. After the water pump 21 delivers water into the water pipe 4, the water is discharged through a set of spray nozzles on the second spray pipe 42 (the first spray pipe 41 and the second spray pipe 42 each have a set of spray nozzles, and the set of spray nozzles are evenly distributed from front to back), spraying and curing the concrete floor. The workers can then push the mobile vehicle 1 to move so that the water is evenly sprayed on the concrete floor. When it is necessary to spray the concrete walls... During spray curing, the valve on the fixed pipe 5 connected to the first spray pipe 41 can be opened (while the valve on the other fixed pipe 5 is closed), allowing the spray nozzles on the first spray pipe to discharge water and spray the vertical wall surface. At the same time, the first motor 71 (the first motor 71 is a servo motor) is started, causing the lead screw 7 to rotate and the moving plate 3 to move upward. The limit rod 81 assists in the movement of the moving plate 3. After the first spray pipe moves upward with the moving plate 3, the wall surface can be sprayed evenly. After the concrete floor and wall surface have been sprayed, the two screws 91 can be twisted to separate them from the lead screw 7 and the limit rod 81, respectively. Then, the workers can rotate the lead screw 7 and the limit rod 81 to change them from a vertical to a horizontal position. The water tank 2 is located between the lead screw 7 and the limit rod 81, and the moving plate 3 is offset from the water tank 2 to facilitate the placement of the moving vehicle 1.

[0010] like Figure 1 , Figure 2 and Figure 3 As shown, a movable frame 31 is slidably connected to one side of the movable plate 3, and a second motor 6 with a rotating shaft fixed to one end of the water pipe 4 is fixed inside the movable frame 31. An electric telescopic rod 32 is fixed on the movable plate 3, and the telescopic end of the electric telescopic rod 32 is connected to the movable frame 31 through a fixed rod. The second motor 6 is a servo motor. After the second motor 6 is started, it can rotate the water pipe 4 slightly to change the angle of the first spray pipe 41 and the second spray pipe 42. The first spray pipe 41 can spray the part of the wall slightly higher than the top of the screw rod 7, while the second spray pipe 42 sprays the angle between the concrete floor and the wall, avoiding spray dead angles. At the same time, when the concrete wall is wide, the first spray pipe 41 can be moved upward to spray the wall. Then, the extension end of the electric telescopic rod 32 drives the moving frame 31 to move horizontally through the fixed rod, so that the first spray pipe 41 corresponds to the unsprayed part of the wall. Then, the first spray pipe 41 moves downward to continue spraying the wall, improving the efficiency of wall spraying.

[0011] like Figure 1 , Figure 2 and Figure 3 As shown, the drain end of the water pump 21 is connected to a flexible hose 22, and the shaft of the water pipe 4 away from the second motor 6 is connected to a conveying pipe 43 that passes through the moving frame 31 and is connected to the flexible hose 22. A battery 23 and a control panel 24 are fixed on the water tank 2, and a water inlet pipe 25 is connected to the water tank 2; a handle 11 is fixed on the moving vehicle 1. After the water pump 21 draws water from the water tank 2, it can convey the water to the conveying pipe 43 through the flexible hose 22, allowing the water to enter the water pipe 4. The flexible hose 22 avoids affecting the lifting, lowering, and lateral movement of the water pipe 4. The battery 23 can supply power to the first motor 71, the second motor 6, the electric telescopic rod 32, the water pump 21, and the solenoid valves on the fixed pipe 5. The control panel 24 is electrically connected to the first motor 71, the second motor 6, the electric telescopic rod 32, the water pump 21, and the solenoid valves on the fixed pipe 5, allowing operators to control the system via the control panel 24.
