Description

Technical Field

[0001] This invention belongs to the field of concrete curing technology, and particularly relates to a concrete curing device for main structure construction. Background Technology

[0002] In the field of building structure construction, concrete curing is a key construction process that ensures the strength of concrete molding, avoids structural cracking, and extends the service life of the building structure. The uniformity of spraying, the stability of operation, and the reliability of equipment directly affect the construction quality and progress of the project. As a core supporting link in the concrete curing process, the spraying water supply structure has a decisive impact on the continuity and efficiency of the entire concrete curing process.

[0003] According to Chinese Patent Publication No. CN222376061U, a wall spraying maintenance mechanism is disclosed, including a mobile vehicle, a water tank, a water pump, a water outlet pipe, a main pipe, spray nozzles, a lifting assembly, and an angle adjustment assembly. The water tank is installed on the mobile vehicle, and an inlet pipe is provided on the top of the water tank. The water pump is installed inside the water tank, one end of the water outlet pipe is connected to the outlet of the water pump, and the other end of the water outlet pipe extends to the outside of the water tank and communicates with the main pipe. Several spray nozzles are evenly distributed on the main pipe and are set facing the components to be sprayed and maintained. The lifting assembly is set on the mobile vehicle, and the main pipe is rotatably mounted on the lifting assembly through the angle adjustment assembly.

[0004] However, in the above scheme, since the water outlet of the spray pipe is always directly exposed to the construction environment, the following disadvantages exist: during the idle period when the concrete curing equipment is shut down, sand, gravel, dust and impurities at the construction site can easily fall into the inside of the spray pipe. After the sand and gravel accumulate, they block the spray pipe, which will lead to poor water flow and uneven spraying in subsequent spraying operations, reducing the curing quality of the main structure. Summary of the Invention

[0005] The purpose of this invention is to address the problem that during the downtime of concrete curing equipment, sand, dust, and other impurities at the construction site easily fall into the spray pipes, causing them to accumulate and clog. This leads to poor water flow and uneven spraying during subsequent spraying operations, thus reducing the curing quality of the main structure. Therefore, this invention proposes a concrete curing device for main structure construction.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A concrete curing device for main structure construction includes a vertical pipe and a mounting frame, wherein the vertical pipe is disposed on one side of the mounting frame, and further includes: Multiple rotating nozzles are rotatably mounted on one side of a vertical pipe; when the vertical pipe supplies water into the rotating nozzles, the rotating nozzles perform circumferential rotating spraying operations around their own axis. Multiple dustproof brushes are slidably disposed on the outlet side of the rotating nozzle to block the outlet of the rotating nozzle; when the rotating nozzle is spraying, the dustproof brushes move outward to expose the outlet of the rotating nozzle.

[0007] Preferred options also include: Multiple adapter tubes are connected to a vertical tube and are arranged along the length of the vertical tube. The rotating nozzle is rotatably connected to the adapter tubes in a sealed manner. Multiple mounting components are fixedly installed inside the adapter tube; Multiple drive fan blades, wherein the drive fan blades are rotatably connected to the mounting component via a rotating shaft; Multiple connectors are fixedly connected inside the rotating nozzle, and one end of the rotating shaft is fixedly connected to the connector.

[0008] Preferred options also include: Multiple sliding plates, one end of which is fixedly connected to a dustproof brush; Multiple movable plates, one end of which is fixedly connected to the side of the sliding plate away from the dustproof brush, and the movable plates are radially slidably disposed on one side of the rotating nozzle; Multiple tension springs are fixedly connected between the moving plate and the rotating nozzle.

[0009] Preferred options also include: Multiple fixed slots are fixedly connected to the outer surface of the rotating nozzle, and the movable plate is slidably connected inside the fixed slots. Multiple fixed slide rods are fixedly connected to a fixed groove seat, and the fixed slide rods are slidably connected to a movable plate.

[0010] Preferred options also include: Multiple counterweights are fixedly connected to the side of the moving plate away from the tension spring.

[0011] Preferred options also include: Multiple sets of air outlet boxes, each set of air outlet boxes consists of two air outlet boxes. The air outlet boxes are fixedly connected to one side of the mounting frame, and the vertical pipe is fixedly connected between the two air outlet boxes. The two air outlet boxes can spray narrow, high-speed airflow and form two air curtains. Multiple sets of flow control plates, each set consisting of two symmetrically arranged flow control plates, are rotatably connected to the air outlet box. The airflow speed is controlled by adjusting the rotation angle of the flow control plates.

[0012] Preferred options also include: Multiple bidirectional racks are slidably disposed on the top of the air outlet box; Multiple electric push rods are fixedly installed on the top of the air outlet box, and the output end of the electric push rod is fixedly connected to one side of the bidirectional rack; Multiple sets of transmission gears, each set consisting of two transmission gears, are fixedly connected to the flow control plate via a connecting shaft. The two transmission gears in the same set are meshed and connected on both sides of a bidirectional rack.

[0013] Preferred options also include: Multiple wind speed sensors are installed on the side of the air outlet box away from the vertical pipe, and the wind speed sensors are electrically connected to the control unit of the electric push rod.

[0014] Preferred options also include: Multiple guide rods are fixedly connected to the top of the air outlet box. A guide groove is provided on the bidirectional rack, and the guide rod is slidably connected in the guide groove.

The water supply tank is used to supply water to the vertical pipe.

[0016] Compared with existing technologies, a concrete curing device for main structure construction that adopts the above-mentioned technical solution has the following beneficial effects: 1. In this invention, during the spraying operation, the counterweight rotates synchronously with the rotating nozzle, generating centrifugal force, which drives the dustproof brush to open radially, and the outlet of the rotating nozzle automatically opens, ensuring a smooth and stable spray of the curing water. After the curing operation is completed, the rotation drive stops, the centrifugal force disappears, and the tension spring pulls the dustproof brush to quickly retract and block the nozzle of the rotating nozzle. Through the centrifugal force combined with the elastic reset structure of the tension spring, the dustproof brush achieves automatic opening and closing control of the nozzle, which can effectively prevent construction site dust, sand and other impurities from entering the interior of the rotating nozzle, preventing the rotating nozzle from becoming clogged from the root, avoiding poor water flow and uneven spraying in subsequent spraying operations, improving the spraying curing effect and extending the service life of the equipment.

[0017] 2. In this invention, a stable high-speed air jet is sprayed from the air outlet box to form an air curtain barrier, thereby blocking external turbulence from intruding into the work area, preventing the spray water from being blown away or deflected by the airflow, improving wind resistance, ensuring that the spray water covers the main structure, and improving the uniformity and adhesion of the spray. In addition, by monitoring the external wind speed through a wind speed sensor, the wind speed of the air curtain formed by the air outlet box is adaptively matched to the wind speed of the external environment, improving the anti-interference capability of the device.

[0021] Please see Figures 1-2 The present invention provides a technical solution: A concrete curing device for main structure construction includes a vertical pipe 7 and a mounting frame 1. The vertical pipe 7 is disposed on one side of the mounting frame 1.

The fixed slide rods 807 are fixedly connected to the sliding groove, and the moving plate 804 has a sliding hole, in which the fixed slide rods 807 are slidably connected.

[0022] The specific usage method and working principle are as follows: When using, with the help of the moving mechanism 2 at the bottom of the mounting frame 1, the whole device is transported to the designated construction position next to the main structure to be maintained, and the main structure is positioned between the two vertical plates. Afterwards, the mounting frame 1 moves along the length of the main structure under the drive of the moving mechanism 2. During this process, the water pump inside the water supply tank 5 starts to work, and delivers clean water to the interior of the vertical pipe 7 through the connecting pipe 9. The water flow is then divided into each adapter pipe 802. After the water flow enters the adapter pipe 802, it impacts the internal drive fan blade 809 and makes the drive fan blade 809 rotate. The drive fan blade 809 drives the rotating nozzle 801 to rotate continuously in the circumferential direction through the rotating shaft and the connecting piece 812. The water flow is sprayed out from the circumferentially rotating rotating nozzle 801 and sprays and maintains the surface of the main structure. During this process, the counterweight 811 rotates synchronously with the rotating nozzle 801, and under the action of centrifugal force, it drives the moving plate 804 to move away from the rotating nozzle 801 radially along the fixed slot 808. The moving plate 804 drives the dustproof brush 805 to separate outward through the sliding plate 803, thereby automatically releasing the blockage of the outlet of the rotating nozzle 801. Clean water is smoothly sprayed out from the outlet of the rotating nozzle 801, completing the rotating spray curing of the concrete main structure. After the maintenance work is completed, the water supply tank 5 stops supplying water to the vertical pipe 7, the drive fan blade 809 stops rotating, the rotating nozzle 801 stops rotating, the centrifugal force acting on the counterweight 811 disappears, at this time, the elastic recoil force of the tension spring 806 pulls the moving plate 804 back to the direction of the rotating nozzle 801, the two dustproof brushes 805 move closer to each other and re-seal the outlet of the rotating nozzle 801 to prevent construction dust and debris from entering the pipe and prevent the pipe from becoming blocked.

[0023] Please see Figures 4-6 It also includes: Multiple sets of air outlet boxes 601, each set of air outlet boxes 601 consists of two air outlet boxes 601. The air outlet boxes 601 are fixedly connected to one side of the mounting frame 1. The vertical pipe 7 is fixedly connected between the two air outlet boxes 601. The two air outlet boxes 601 can spray narrow, high-speed airflow and form two air curtains, thereby reducing the interference of external airflow on the water jet sprayed by the rotating nozzle 801. The vertical pipe 7 is equipped with mounting rings at both the upper and lower ends, and the mounting rings are fixedly connected between the two air outlet boxes 601. Multiple sets of flow control plates 602 are provided, each set consisting of two symmetrically arranged flow control plates 602. The flow control plates 602 are rotatably connected to the air outlet box 601. The airflow velocity is controlled by adjusting the rotation angle of the flow control plates 602. Each flow control plate 602 has a straight surface and an arc surface, with the arc surface serving as the contact surface for high-speed airflow. Both ends of the flow control plate 602 are connected to connecting shafts, which, in conjunction with bearings, enable the rotatable connection between the flow control plate 602 and the air outlet box 601. The curved side surface of the flow control plate 602 is always in contact with the inner wall of the air outlet box 601, sealing the gap between them. This ensures that the airflow can only exit from the air outlet in the middle of the air outlet box 601, effectively preventing airflow leakage from the gaps on both sides. See Figures 5-6 Multiple bidirectional racks 604 are slidably disposed on the top of the air outlet box 601, wherein the bottom surface of the bidirectional racks 604 is in contact with the top surface of the air outlet box 601; Multiple electric push rods 603 are fixedly installed on the top of the air outlet box 601. The output end of the electric push rod 603 is fixedly connected to one side of the bidirectional rack 604. The electric push rod 603 is equipped with a control unit, which is used to adjust the output stroke of the electric push rod 603 in accordance with the data detected by the wind speed sensor 609. Multiple sets of transmission gears 605, each set of transmission gears 605 consists of two transmission gears 605, the transmission gears 605 are fixedly connected to the flow control plate 602 through a connecting shaft, and the two transmission gears 605 in the same set are meshed and connected to both sides of the bidirectional rack 604. Multiple wind speed sensors 609 are installed on the side of the air outlet box 601 away from the vertical pipe 7. The wind speed sensors 609 are electrically connected to the control unit of the electric push rod 603. The wind speed sensor 609 is model JT1420. Since the two wind speed sensors 609 installed on the same group of air outlet boxes 601 are set back to back, the wind speed detected by the two wind speed sensors 609 is inconsistent. After the data is transmitted to the control unit in the electric push rod 603, the control unit takes the larger value and adjusts the output stroke of the electric push rod 603. Multiple guide rods 607 are fixedly connected to the top of the air outlet box 601. A guide groove 606 is provided on the bidirectional rack 604, and the guide rods 607 are slidably connected in the guide groove 606. Multiple top plates 608 are fixedly connected to the top of the guide rod 607. The bottom of the top plate 608 is in contact with the top of the bidirectional rack 604. The top plate 608 is used to limit the position of the bidirectional rack 604.

[0024] The specific usage method and working principle are as follows: During the spraying operation, the air pump 3 delivers high-speed airflow into the air outlet box 601 through the air supply pipe 4. Two wind speed sensors 609 installed on the outside of the air outlet box 601 are arranged back to back to detect the external environmental wind speed on both sides of the vertical pipe 7 in real time, and transmit the two sets of wind speed detection data to the control unit inside the electric push rod 603 in a synchronous manner. The control unit automatically compares the two sets of wind speed values ​​and selects the larger wind speed value as the control benchmark. It adaptively adjusts the extension and retraction output stroke of the electric push rod 603. The electric push rod 603 pushes the bidirectional rack 604 to move. During the movement of the bidirectional rack 604, the guide rod 607 cooperates with the guide groove 606 at the bottom of the bidirectional rack 604 to achieve linear guidance. The top plate 608 limits the bidirectional rack 604 from the upper side. At the same time, the bottom surface of the bidirectional rack 604 always fits against the top surface of the air box 601 to prevent the bidirectional rack 604 from moving up and down or deviating. When the bidirectional rack 604 slides, it synchronously drives the meshing transmission gears 605 on both sides to rotate in opposite directions, thereby causing the flow control plate 602, which is fixed coaxially with the transmission gear 605, to rotate synchronously. This changes the distance and angle between the two flow control plates 602, altering the ventilation cross-sectional area inside the air outlet box 601, and thus adjusting the airflow speed. This allows the wind speed of the air curtain to match the maximum wind speed of the external environment, preventing external airflow from interfering with the spray water flow and improving the spraying effect on the main structure.
