Description

Technical Field

[0001] This invention belongs to the field of concrete curing technology, and in particular relates to an intelligent concrete curing equipment and curing method. Background Technology

[0002] If concrete is not cured in time after pouring, the water in the concrete will evaporate too quickly, resulting in 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. At the same time, premature evaporation of water before the concrete has sufficient strength will also cause significant shrinkage deformation and drying shrinkage cracks. Therefore, the initial curing work after concrete pouring is very important.

[0003] During the concrete pouring process, concrete test blocks are usually made. These test blocks need to undergo compressive strength tests to determine whether the concrete meets the strength requirements. When producing different types of concrete, it is often necessary to select and test different types of concrete. The test results of concrete specimens often represent the quality of that type of concrete product. After the concrete specimens are made, concrete curing equipment is needed to cure the concrete test blocks to facilitate the subsequent acquisition of quality data for that type of concrete.

[0004] Currently, most existing concrete curing equipment can only spray concrete specimens for curing, and cannot perform film curing according to different types of concrete specimens. The curing method is relatively simple and the scope of application is limited. It cannot adapt to the concrete curing operations in different environments, and the effect is not good. At the same time, when spraying water to humidify concrete blocks, it is not convenient to spray water on multiple sides of the concrete blocks, and the humidification effect is not good.

[0005] To address this issue, we designed an intelligent concrete curing equipment and method. Summary of the Invention

The film covering mechanism includes: The support shaft has a rectangular groove on the rear surface of the inner wall of the curing box. An L-shaped support plate is fixed to one end of the inner side of the rectangular groove. The support shaft rotatably passes through the L-shaped support plate. The rear end of the support shaft is rotatably connected to the inner wall of the rectangular groove. A take-up roller is fitted on the support shaft via a locking buckle. A film is wound on the take-up roller. A lead screw is installed in the rectangular groove. One end of the lead screw passes through the L-shaped support plate and rotatably engages with the L-shaped support plate. A movable block is threaded on the lead screw. A traction rod is fixed to the front end of the movable block. A clamping assembly is installed on the traction rod. A first bevel gear is fixed to one end of the lead screw. A second bevel gear is fixed to the rear end of the support shaft. The first bevel gear and the second bevel gear mesh with each other.

[0007] The clamping assembly includes an arc-shaped clamp plate that cooperates with the outer wall of the traction rod. A movable rod is movably embedded at the end of the traction rod away from the first bevel gear. One end of the movable rod passes through the arc-shaped clamp plate and is fixed with a pull ring. The arc-shaped clamp plate is fixedly connected to the movable rod. A disc is fixed at the end of the movable rod away from the pull ring. A spring is fixed between the disc and the traction rod, and the spring is sleeved on the outside of the movable rod.

[0008] Two guide rods are fixed inside the rectangular groove. The guide rods pass through the movable block and slide with the movable block. An installation groove is provided on one side of the outer wall of the maintenance box. A motor is installed in the installation groove. The output end of the motor is connected to the end of the lead screw away from the first bevel gear.

[0009] The humidification mechanism includes a water supply pipe. A circular hole is opened through the top of the maintenance box. The water supply pipe is movably disposed in the circular hole. The lower end of the water supply pipe extends into the interior of the maintenance box and is connected to a spray pipe. The spray pipe has an L-shaped structure and is equipped with several nozzles. The nozzles face the placement plate. A cylinder is installed on the top of the maintenance box. A lifting plate is fixedly sleeved on the upper side of the outer wall of the water supply pipe. The telescopic end of the cylinder is fixedly connected to the lifting plate.

[0010] A vortex housing is fixed to the lower side of the rear surface of the maintenance box. A turbine blade is movably arranged inside the vortex housing. A rotating shaft is rotatably arranged inside the vortex housing. The front end of the rotating shaft extends into the maintenance box and is fixedly connected to a third bevel gear. The rotating shaft rotates in conjunction with the maintenance box. The turbine blade is fixedly sleeved on the rotating shaft. A fourth bevel gear is fixedly sleeved on the lower side of the outer wall of the support rod. The fourth bevel gear meshes with the third bevel gear. A water supply pipe is connected to one side of the vortex housing. A telescopic hose is connected between the end of the water supply pipe away from the vortex housing and the upper end of the water supply pipe. A water inlet pipe is connected to one side of the bottom of the vortex housing. A valve is installed on the water inlet pipe.

[0011] The curing box has two heating chambers facing each other inside, and several heating tubes are installed in the heating chambers. A temperature and humidity sensor is installed on the top of the inner side of the curing box. A door is movably installed on the front side of the curing box, and a controller is installed on the door.

[0012] The box door is equipped with a transparent window. The bottom of the inner side of the curing box is inclined. A mesh plate is provided on one side of the bottom surface of the inner side of the curing box. A water storage chamber is provided on the lower side of the mesh plate. The water storage chamber is located inside the wall panel at the bottom of the curing box. The bottom of the water storage chamber is inclined. A drain hole is provided through one side of the inner wall of the water storage chamber. A sealing block is provided in the drain hole.

[0013] A maintenance method includes the following steps: Step 1: First, move the curing box to a suitable position using the casters. When curing the concrete specimen, open the box door, pull out the movable end of the film being wound on the take-up roller, and wrap it around the traction rod. Under the elastic action of the spring, the arc-shaped clamp will be tightly attached to the traction rod to clamp and fix the movable end of the film. At the same time, connect the water inlet pipe to the external water supply mechanism. If the concrete specimen needs to be covered with film, proceed to Step 2; otherwise, proceed to Step 5. Step 2: Start the motor. The motor drives the lead screw to rotate. Combined with the meshing of the first and second bevel gears, the support shaft rotates synchronously. The rotation of the support shaft drives the take-up roller to rotate, releasing the film. At the same time, under the action of the movable block, the traction rod moves away from the support shaft, thus pulling the released film past the top of the placement plate until the movable block moves to the far right, and then proceed to Step 3. Step 3: Place the concrete specimen to be cured onto the film on top of the placement board, then remove it from the traction rod through the movable end of the film, and cut the film on the take-up roller so that the film completely wraps around the outside of the concrete specimen, and proceed to Step 4. Step 4: Monitor the temperature and humidity inside the curing chamber in real time using a temperature and humidity sensor, and transmit the monitoring data to the controller. When the temperature needs to be increased, activate the heating element through the controller to heat the inside of the curing chamber. When humidification is required, first open the film covering the concrete specimen and proceed to Step 6. Step 5: Place the concrete specimens to be cured on the placement plate, monitor the temperature and humidity inside the curing chamber in real time using temperature and humidity sensors, and transmit the monitoring data to the controller. When the temperature needs to be increased, activate the heating element through the controller to heat the inside of the curing chamber. Step Six: When water spraying and humidification are required, the drive cylinder retracts. Under the action of the lifting plate, combined with the water supply pipe, the water spray pipe moves downward, so that several nozzles are directed toward the top and rear side of the concrete specimen. At the same time, the valve on the water inlet pipe is opened, and water is supplied to the water inlet pipe through the external water supply mechanism. The water is then transported to the water spray pipe through the volute, water delivery pipe, telescopic hose and water supply pipe, and finally sprayed onto the concrete specimen by the nozzles. When the water flows through the inner cavity of the vortex shell and impacts the turbine blades, it drives the shaft to rotate. Combined with the meshing of the third and fourth bevel gears, it drives the support rod and the placement plate to rotate, which in turn drives the placed concrete specimen to rotate, so as to achieve the purpose of spraying water to humidify the periphery of the concrete specimen. The corresponding water flows downward into the water storage chamber for temporary storage, and then proceeds to step seven. Step 7: After the concrete has cured, open the box door to take out the concrete specimen, and open the sealing block to drain the water from the water storage chamber.

[0014] The present invention has the following beneficial effects: This invention facilitates the clamping and fixing of the movable end of the film through the clamping assembly and the traction rod. At the same time, the motor facilitates the rotation of the lead screw. With the threaded engagement between the movable block and the lead screw, it is easy to adjust the movable block to move away from the L-shaped support plate. Combined with the meshing of the first bevel gear and the second bevel gear, the support shaft rotates synchronously, which in turn drives the winding roller to rotate, releasing the wound film. Simultaneously, as the movable block drives the traction rod to move, the released film is pulled, achieving the purpose of pulling the film outward, which facilitates the subsequent covering of concrete specimens. Meanwhile, it can be easily connected to an external water supply system through the water inlet pipe. Under the combined action of the vortex shell, water delivery pipe, telescopic hose, and water conveyance pipe, water is delivered to the spray pipe and finally sprayed onto the concrete specimen through the nozzle to achieve the purpose of humidifying the concrete specimen. It realizes different curing methods and is suitable for curing concrete specimens in different environments. It solves the shortcomings of existing concrete curing equipment, which can mostly only spray concrete specimens for curing, cannot perform film curing according to different types of concrete specimens, has a relatively simple curing method, a limited scope of application, cannot adapt to concrete curing operations in different environments, and has poor use effect. When water flows into the vortex casing and impacts the turbine blades, it drives the shaft to rotate, which in turn drives the third bevel gear to rotate. The meshing of the third and fourth bevel gears, combined with the rotation of the support rod, drives the placement plate to rotate, which in turn drives the placed concrete specimen to rotate. This facilitates water spraying and humidification of the top and sides of the concrete, ensuring the curing effect of the concrete specimen. It solves the drawback of existing concrete curing equipment that is not convenient to spray water on multiple sides of the concrete specimen, resulting in poor humidification effect.

[0020] In the description of this invention, it should be understood that the terms "upper," "middle," "outer," "inner," etc., which indicate orientation or positional relationship, are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this invention.

[0021] Please see Figure 1 - Figure 11 As shown, this invention is an intelligent concrete curing device, including a curing box 1. A support rod 2 is rotatably mounted on the bottom inner side of the curing box 1, and a placement plate 3 is fixed to the upper end of the support rod 2. A film covering mechanism is provided inside the curing box 1, and a humidification mechanism is provided on the curing box 1. The film covering mechanism includes: A rectangular groove 4 is formed on the rear surface of the inner wall of the support shaft 5 and the curing box 1. An L-shaped support plate is fixed to one end of the inner side of the rectangular groove 4. The support shaft 5 is rotatably passed through the L-shaped support plate. The rear end of the support shaft 5 is rotatably connected to the inner wall of the rectangular groove 4. A take-up roller 6 is fitted on the support shaft 5 through a locking buckle. A film is wound on the take-up roller 6. A lead screw 7 is set in the rectangular groove 4. One end of the lead screw 7 passes through the L-shaped support plate and is rotatably engaged with the L-shaped support plate. A movable block 8 is threaded on the lead screw 7. A traction rod 9 is fixed to the front end of the movable block 8. A clamping assembly is set on the traction rod 9. A first bevel gear 10 is fixed to one end of the lead screw 7. A second bevel gear 11 is fixed to the rear end of the support shaft 5. The first bevel gear 10 and the second bevel gear 11 mesh with each other.

[0022] In the above structure, the clamping assembly and the traction rod 9 facilitate the clamping and fixing of the movable end of the film. At the same time, the threaded engagement between the movable block 8 and the lead screw 7 facilitates the adjustment of the movable block 8 to move away from the L support plate. Combined with the meshing action of the first bevel gear 10 and the second bevel gear 11, the support shaft 5 is driven to rotate synchronously, which in turn drives the winding roller 6 to rotate, releasing the wound film. Simultaneously, as the movable block 8 drives the traction rod 9 to move, the released film is pulled to move, achieving the purpose of pulling the film outward, which facilitates the subsequent covering of the concrete specimen.

[0023] The clamping assembly includes an arc-shaped clamping plate 12, which cooperates with the outer wall of the traction rod 9. A movable rod 14 is movably embedded at the end of the traction rod 9 away from the first bevel gear 10. One end of the movable rod 14 passes through the arc-shaped clamping plate 12 and is fixed with a pull ring 13. The arc-shaped clamping plate 12 is fixedly connected to the movable rod 14. A disc 16 is fixed at the end of the movable rod 14 away from the pull ring 13. A spring 15 is fixed between the disc 16 and the traction rod 9. The spring 15 is sleeved on the outside of the movable rod 14.

[0024] Two guide rods 17 are fixed inside the rectangular groove 4. The guide rods 17 pass through the movable block 8 and slide with the guide rods 17. The guide rods 17 effectively limit and guide the movable block 8, ensuring the stability of the movable block 8 during movement. A mounting groove is provided on one side of the outer wall of the curing box 1. A motor 18 is installed in the mounting groove. The output end of the motor 18 is connected to the end of the lead screw 7 away from the first bevel gear 10.

[0025] The humidification mechanism includes a water supply pipe 19. A circular hole is opened through the top of the curing box 1, and the water supply pipe 19 is movably installed in the circular hole. The lower end of the water supply pipe 19 extends into the interior of the curing box 1 and is connected to a spray pipe 20. The spray pipe 20 has an L-shaped structure and is equipped with several nozzles 21. The nozzles 21 face the placement plate 3. A cylinder 23 is installed on the top of the curing box 1. A lifting plate 22 is fixedly sleeved on the upper side of the outer wall of the water supply pipe 19. The telescopic end of the cylinder 23 is fixedly connected to the lifting plate 22. Through the cooperation of the cylinder 23 and the lifting plate 22, the up and down movement of the water supply pipe 19 and the spray pipe 20 is adjusted, which facilitates the movement of the film by the traction rod 9.

[0026] A vortex housing 24 is fixed to the lower side of the rear surface of the maintenance box 1. A turbine blade 25 is movably installed inside the vortex housing 24. A rotating shaft 26 is rotatably installed inside the vortex housing 24. The front end of the rotating shaft 26 extends into the maintenance box 1 and is fixedly connected to a third bevel gear 27. The rotating shaft 26 and the maintenance box 1 are rotatably engaged. The turbine blade 25 is fixedly sleeved on the rotating shaft 26. A fourth bevel gear 28 is fixedly sleeved on the lower side of the outer wall of the support rod 2. The fourth bevel gear 28 meshes with the third bevel gear 27. A water supply pipe 29 is connected to one side of the vortex housing 24. A telescopic hose 30 is connected between the end of the water supply pipe 29 away from the vortex housing 24 and the upper end of the water supply pipe 19. A water inlet pipe 31 is connected to one side of the bottom of the vortex housing 24. A valve is installed on the water inlet pipe 31.

[0027] In the above structure, the water inlet pipe 31 facilitates connection with an external water supply mechanism. Under the combined action of the vortex shell 24, water delivery pipe 29, telescopic hose 30, and water conveyance pipe 19, water is delivered to the spray pipe 20 and finally sprayed onto the concrete specimen through the nozzle 21 to achieve the purpose of humidifying the concrete specimen. When the water flows into the vortex shell 24 and impacts the turbine blades 25, it drives the rotating shaft 26 to rotate, which in turn drives the third bevel gear 27 to rotate. Under the meshing action of the third bevel gear 27 and the fourth bevel gear 28, combined with the rotation setting of the support rod 2, the placement plate 3 is driven to rotate, which in turn drives the placed concrete specimen to rotate, which facilitates water spraying and humidification of the top and surrounding sides of the concrete, ensuring the curing effect of the concrete specimen.

[0028] The curing chamber 1 has two heating chambers 32 facing each other inside. Several heating tubes 33 are installed in the heating chambers 32 to facilitate heating of the inner cavity of the curing chamber 1, thereby achieving the purpose of temperature regulation during the curing of concrete specimens. A temperature and humidity sensor 34 is installed on the top of the inner side of the curing chamber 1. A door 35 is movably installed on the front side of the curing chamber 1, and a controller 36 is installed on the door 35.

[0029] A transparent window is provided on the door 35 to facilitate observation of the concrete specimens inside the curing chamber 1. The bottom of the inner side of the curing chamber 1 is inclined, and a mesh plate is provided on one side of the bottom inner side of the curing chamber 1. A water storage chamber 38 is provided under the mesh plate to facilitate the collection of excess water during the humidification process. The water storage chamber 38 is located in the wall panel at the bottom of the curing chamber 1. The bottom of the inner cavity of the water storage chamber 38 is inclined, and a drainage hole is provided through one side of the inner wall of the water storage chamber 38. A sealing block is provided in the drainage hole to facilitate the drainage of the water collected in the water storage chamber 38 after curing. The mesh plate effectively prevents debris from falling off the concrete specimen from entering the water storage chamber 38 and clogging the drainage hole.

[0030] A maintenance method includes the following steps: Step 1: First, with the help of the casters 37, move the curing box 1 to a suitable position. When it is necessary to cure the concrete specimen, open the box door 35, pull out the movable end of the film wound on the take-up roller 6, and wrap it around the traction rod 9. Under the elastic action of the spring 15, drive the arc-shaped clamp 12 to stick tightly to the traction rod 9 to achieve the purpose of clamping and fixing the movable end of the film. At the same time, connect the water inlet pipe 31 to the external water supply mechanism. If it is necessary to cover the concrete specimen, proceed to step 2. If it is not necessary to cover, proceed to step 5. Step 2: Start the motor 18, which drives the lead screw 7 to rotate. Combined with the meshing of the first bevel gear 10 and the second bevel gear 11, the support shaft 5 rotates synchronously. The rotation of the support shaft 5 drives the take-up roller 6 to rotate, releasing the film. At the same time, under the action of the movable block 8, the traction rod 9 moves away from the support shaft 5, thereby pulling the released film past the top of the placement plate 3 until the movable block 8 moves to the far right, and then proceed to step 3. Step 3: Place the concrete specimen to be cured onto the film on top of the placement plate 3, then remove it from the traction rod 9 through the movable end of the film, and cut the film on the take-up roller 6 so that the film completely wraps around the outside of the concrete specimen, and proceed to step 4. Step 4: The temperature and humidity inside the curing chamber 1 are monitored in real time by the temperature and humidity sensor 34, and the monitoring data is transmitted to the controller 36. When the temperature needs to be increased, the heating tube 33 is activated by the controller 36 to heat the inside of the curing chamber 1. When humidification is needed, the film covering the concrete specimen is opened first, and then proceed to step 6. Step 5: Place the concrete specimen to be cured on the placement plate 3. The temperature and humidity inside the curing chamber 1 are monitored in real time by the temperature and humidity sensor 34, and the monitoring data is transmitted to the controller 36. When the temperature needs to be increased, the heating tube 33 is activated by the controller 36 to heat the inside of the curing chamber 1. Step Six: When water spraying and humidification are required, the drive cylinder 23 retracts. Under the action of the lifting plate 22, combined with the water supply pipe 19, the water spray pipe 20 moves downward, so that several nozzles 21 are directed toward the top and rear side of the concrete specimen. At the same time, the valve on the water inlet pipe 31 is opened, and water is supplied to the water inlet pipe 31 through the external water supply mechanism. The water is then transported to the water spray pipe 20 through the vortex shell 24, the water supply pipe 29, the telescopic hose 30, and the water supply pipe 19. Finally, water is sprayed onto the concrete specimen under the action of the nozzles 21. When the water flows through the inner cavity of the vortex shell 24 and impacts the turbine blades 25, it drives the rotating shaft 26 to rotate. Combined with the meshing of the third bevel gear 27 and the fourth bevel gear 28, it drives the support rod 2 and the placement plate 3 to rotate, thereby driving the placed concrete specimen to rotate, so as to achieve the purpose of spraying water to humidify the circumferential side of the concrete specimen. The corresponding water flows downward into the water storage chamber 38 for temporary storage, and then proceeds to step seven. Step 7: After the concrete has cured, open the box door 35 to take out the concrete specimen, and open the sealing block to drain the water in the water storage chamber 38.
