Description
Technical Field
[0001] This utility model relates to the field of concrete preparation technology, specifically to a concrete curing device for concrete preparation. Background Technology
[0002] Concrete curing involves artificially creating specific humidity and temperature conditions to allow freshly poured concrete to harden and gain strength normally or at an accelerated pace. The gradual hardening and strength gain of concrete is a result of cement hydration, which requires certain temperature and humidity conditions. If these conditions are not present in the surrounding environment, artificial curing of the concrete is necessary.
[0003] This application improves upon the existing technology, in which existing geotextile unwinding devices mostly adopt a fixed shaft structure, the installation and disassembly process of the unwinding roller is cumbersome, and it takes a lot of manpower and time to replace the geotextile roll. Moreover, geotextile wrinkles and displacement are prone to occur during the unwinding process, affecting the adhesion to the concrete surface and thus reducing the curing quality.

[0007] For example, in a concrete curing device for concrete preparation provided in at least one embodiment of the present invention, a square slot is provided on both sides of the unwinding roller, and the square slot is adapted to the square block.
[0008] For example, in at least one embodiment of the present invention, a concrete curing device for concrete preparation is provided, which further includes: a symmetrically distributed guide groove is provided at the bottom of the base plate, and a movable rod is slidably connected to the inner wall of the guide groove, and the movable rod is fixedly connected to the movable plate.
[0009] For example, in at least one embodiment of the present invention, a concrete curing device for concrete preparation is provided, which further includes: a second motor fixedly connected to one of the support plates, and the output shaft of the second motor fixedly connected to a bidirectional screw.
[0010] For example, in a concrete curing device for concrete preparation provided in at least one embodiment of the present invention, a first motor is fixedly connected to one of the mounting plates, and the output shaft of the first motor is fixedly connected to the sleeve.
[0011] For example, in at least one embodiment of the present invention, a concrete curing device for concrete preparation further includes: a vertical plate fixedly connected to the top of the mounting plate, a first connecting pipe fixedly connected between two vertical plates, and a plurality of equidistantly distributed first spray heads fixedly connected to the side of the first connecting pipe away from the water tank.
[0012] For example, in at least one embodiment of the present invention, a concrete curing device for concrete preparation further includes: a second connecting pipe fixedly connected to the bottom of the base plate, and a plurality of equidistantly distributed second spray heads fixedly connected to the bottom of the second connecting pipe.
[0013] For example, in at least one embodiment of the present invention, a concrete curing device for concrete preparation is provided, which further includes: a water outlet pipe is fixedly connected to the bottom of the water tank near the first connecting pipe, a water pump is fixedly connected to the other end of the water outlet pipe, and the water pump is fixedly connected to the base plate; a conveying pipe is fixedly connected to the outlet of the water pump, and the conveying pipe is fixedly connected to the first connecting pipe; a second solenoid valve is installed on the conveying pipe; a conduit is fixedly connected to the bottom of the conveying pipe, and a first solenoid valve is installed on the conduit.
[0014] For example, in at least one embodiment of the present invention, a concrete curing device for concrete preparation is provided, which further includes: a control panel fixedly connected to the top of the base plate, the control panel being electrically connected to a first solenoid valve and a second solenoid valve, and the control panel being electrically connected to a water pump, a first motor and a second motor.
[0015] The beneficial effects of the embodiments of this utility model are as follows: 1. In this utility model application, during use, the device moves and controls the water pump, the first solenoid valve, and the second solenoid valve through the control panel. The water pump draws water from the water tank through the outlet pipe. The first solenoid valve opens, allowing water to enter the second connecting pipe through the conduit. The second spray head sprays water onto the concrete surface to wet it. Then, the first motor is started, and the output shaft of the first motor rotates, driving the sleeve to rotate. Through the cooperation of the sliding groove and the sliding strip, as well as the cooperation of the square slot and the square block, the sleeve drives the unwinding roller to rotate, thereby releasing the geotextile and making the geotextile adhere to the concrete surface. Then, the second solenoid valve opens, and water enters the first connecting pipe and is sprayed out through the first spray head. Spraying water onto the laid geotextile allows the geotextile to quickly absorb water, filling the gaps between its fibers with moisture and forming a "wet isolation layer" that adheres tightly to the concrete surface. The water-saturated geotextile continuously releases water vapor to the concrete surface, while blocking the evaporation of water caused by external air flow, providing a stable humid environment for cement hydration and preventing the concrete from developing shrinkage cracks due to lack of water. 2. During installation, the second motor is started via the control panel. The output shaft of the second motor rotates, driving a bidirectional screw to rotate. The bidirectional screw rotates, causing two movable plates to move towards each other. The movable plates drive the connecting ring and the movable column to move, so that the movable column extends out of the sleeve and drives the square locking block into the square locking groove until the connecting plate abuts against the unwinding roller. The connecting ring and the movable column are rotatably connected, and then cooperate with the sliding groove and the sliding strip, so that when the sleeve rotates, it can drive the movable column to rotate. The square locking groove and the square locking block cooperate so that when the movable column rotates, it drives the square locking block to rotate, which in turn drives the unwinding roller to rotate. This facilitates installation and disassembly, and makes it easy to install geotextiles. Attached Figure Description

[0024] like Figures 1-5 As shown, this invention illustrates a concrete curing device for concrete preparation according to one embodiment of the present invention. It includes a base plate 1, with a water tank 2 fixedly connected to the top of the base plate 1. The water tank 2 has a covered inlet (not shown in the figure) on its top. A liquid level sensor is installed on the inner wall, and a liquid level observation window is provided on the corresponding position of the outer wall to ensure timely water replenishment. Symmetrically distributed mounting plates 11 are fixedly connected to one side of the base plate 1. Sleeves 24 are rotatably connected to the sides of the two mounting plates 11 that are close to each other. A movable column 27 is slidably connected to the inner wall of the sleeve 24. A square locking block 31 is fixedly connected to one end of the movable column 27 extending out of the sleeve 24. A connecting plate 29 is fixedly connected to the outer wall of the square locking block 31. The two connecting plates... The unwinding roller 12 is abutted between the discs 29, and the pressure during abutment is 5-10N. This pressure is achieved by the thread preload of the bidirectional screw 21 to ensure that the unwinding roller 12 does not slip and is easy to disassemble. The outer wall of the movable column 27 is rotatably connected to the connecting ring 28. The bottom of the base plate 1 is fixedly connected to the symmetrically distributed support plates 19.

The outer walls of both ends of the bidirectional screw 21 are threadedly connected to the movable plates 20, and the movable plates 20 are fixedly connected to the connecting ring 28.

The unwinding roller 12 is fixed by the square locking groove 30 and the square locking block 31.

[0028] In some examples, a second motor 14 is fixedly connected to one of the support plates 19, and the output shaft of the second motor 14 is fixedly connected to the bidirectional screw 21. The second motor 14 is a 60W DC motor. The second motor 14 drives the bidirectional screw 21, causing the bidirectional screw 21 to rotate and drive the movable plate 20 to move.
[0029] In some examples, a first motor 13 is fixedly connected to one of the mounting plates 11. The output shaft of the first motor 13 is fixedly connected to the sleeve 24. The first motor 13 is a 42 stepper motor. The first motor 13 drives the sleeve 24 to rotate, thereby causing the unwinding roller 12 to rotate.
[0030] In some examples, the top of the mounting plate 11 is fixedly connected to a vertical plate 9, and a first connecting pipe 8 is fixedly connected between two vertical plates 9. Multiple equidistant first spray heads 10 are fixedly connected to the side of the first connecting pipe 8 away from the water tank 2, and the geotextile after being laid is moisturized through the first spray heads 10.
[0031] In some examples, a second connecting pipe 15 is fixedly connected to the bottom of the base plate 1, and a plurality of equally spaced second spray nozzles 16 are fixedly connected to the bottom of the second connecting pipe 15. The concrete is initially sprayed through the second spray nozzles 16 to facilitate the adhesion of the geotextile to the concrete ground during the laying process.
[0032] The first connecting pipe 8 and the second connecting pipe 15 both have a diameter of DN20 and are matched with 8-10 first spray heads 10 / second spray heads 16 (orifice diameter 1.5mm) to ensure uniform spraying. The distance between the first spray head 10 and the second spray head 16 is 12cm, the spray angle is 60°, and the spray range of adjacent spray heads overlaps by 10% to ensure coverage without dead corners.
[0033] In some examples, a water outlet pipe 3 is fixedly connected to the bottom of the water tank 2 near the first connecting pipe 8, and a water pump 4 is fixedly connected to the other end of the water outlet pipe 3. The water pump 4 is fixedly connected to the base plate 1, and a delivery pipe 6 is fixedly connected to the outlet of the water pump 4. The delivery pipe 6 is fixedly connected to the first connecting pipe 8, and a second solenoid valve 7 is installed on the delivery pipe 6. A conduit 18 is fixedly connected to the bottom of the delivery pipe 6, and a first solenoid valve 5 is installed on the conduit 18. The water inlet into the second connecting pipe 15 and the first connecting pipe 8 is controlled by the first solenoid valve 5 and the second solenoid valve 7.
[0034] Pump 4 is a miniature centrifugal pump with a head ≥5m and a flow rate ≥10L / min to meet the water supply needs of multiple spray heads working simultaneously.
[0035] In some examples, a control panel 17 is fixedly connected to the top of the base plate 1. The control panel 17 is electrically connected to the first solenoid valve 5 and the second solenoid valve 7. The control panel 17 is also electrically connected to the water pump 4, the first motor 13 and the second motor 14. The control panel 17 is an STM32 series microcontroller control board.
[0036] Working principle and usage process of this utility model: In this application, the bottom of the base plate 1 is equipped with symmetrically distributed casters (with braking function), and the caster support device moves the base plate 1 by pushing it. In this application, during use, the device moves, and the water pump 4, the first solenoid valve 5, and the second solenoid valve 7 are controlled via the control panel 17. The water pump 4 draws water from the water tank 2 through the outlet pipe 3. The first solenoid valve 5 opens, allowing water to enter the second connecting pipe 15 through the conduit 18. The water is then sprayed onto the concrete surface through the second spray head 16 to wet it. Afterward, the first motor 13 is started, and the output shaft of the first motor 13 rotates, driving the sleeve 24 to rotate. Through the cooperation of the sliding groove 25 and the sliding strip 26, as well as the cooperation of the square slot 30 and the square block 31, the sleeve 24 is driven to unwind. Roller 12 rotates, which in turn feeds the geotextile, allowing it to adhere to the concrete surface. Then, the second solenoid valve 7 opens, and water enters the first connecting pipe 8 and is sprayed out through the first spray head 10. Spraying water onto the laid geotextile allows it to quickly absorb water, filling the gaps between its fibers with moisture and forming a "wet isolation layer" that adheres tightly to the concrete surface. The water-saturated geotextile continuously releases moisture onto the concrete surface while blocking moisture evaporation caused by external airflow, providing a stable humid environment for cement hydration and preventing the concrete from developing shrinkage cracks due to lack of water. The rotation speed of the unwinding roller 12 is linked to the device movement speed via the control panel 17 (when the movement speed is 0.5-1m / min, the rotation speed corresponds to 0.5-1r / min), ensuring uniform tension during geotextile laying; the unwinding roller 12 is adapted to geotextiles with a width of 1-2m and matches the coverage range (width 1-2m) of the first spray head 10 and the second spray head 16. In this application, during installation, the second motor 14 is started via the control panel 17. The output shaft of the second motor 14 rotates, driving the bidirectional screw 21 to rotate. The rotation of the bidirectional screw 21 drives the two movable plates 20 to move towards each other. The movable plates 20 drive the connecting ring 28 and the movable column 27 to move, causing the movable column 27 to extend out of the sleeve 24 and drive the square locking block 31 into the square locking groove 30 until the connecting plate 29 abuts against the unwinding roller 12. The connecting ring 28 is rotatably connected to the movable column 27, and then cooperates with the sliding groove 25 and the sliding strip 26, so that when the sleeve 24 rotates, it can drive the movable column 27 to rotate. The square locking groove 30 and the square locking block 31 cooperate so that when the movable column 27 rotates, it drives the square locking block 31 to rotate, which in turn drives the unwinding roller 12 to rotate. This facilitates installation and disassembly, and makes it easy to install geotextile.
