Description

Technical Field

[0001] The present invention relates to the technical field of concrete slab curing equipment, and in particular to an automatic curing device for precast concrete slabs. Background Art

[0002] Precast concrete slabs refer to concrete slabs processed and produced in a factory in a standardized and mechanized manner. The use of precast concrete slabs has the advantage of shortening the construction period. After the precast concrete slabs are manufactured and formed, in order to prevent the concrete slabs from cracking due to too low humidity, it is necessary to carry out timely spraying and curing work on the precast concrete slabs.

[0003] In the prior art, when carrying out the spraying and curing work of precast concrete slabs, most of the clear water is directly sprayed on the surface of the precast concrete slabs to achieve the curing work of the concrete slabs. To ensure that the surface of the concrete slabs can be covered by water, the spraying range of the clear water is larger than the area of the concrete slabs. The water that is not sprayed onto the surface of the concrete slabs and the water that flows down from the concrete slabs cannot be recycled and reused, thus causing waste of water resources.

[0007] By adopting the above technical solutions, when curing the precast concrete slabs, the concrete slabs are placed on the base, and the concrete slabs are supported by the support mechanism. Then, the water pump is started to transport the water in the water storage box to the water pipe through the inlet pipe and the outlet pipe.

[0008] Preferably, a partition is fixedly connected to the inner side wall of the bottom end of the water storage box; the partition divides the water storage box into a first cavity located at the bottom of the water leakage port and a second cavity communicated with the inside of the water inlet pipe.

During the rotation of the first bevel gear, the second bevel gear and the first rotating shaft are driven to rotate. Under the driving action of the first belt pulley, the second belt pulley and the belt, the second rotating shaft drives the second lead screw to rotate, so that the scraping plate slides along the bottom of the water storage box, reducing the possibility that dirt and impurities adhere to the inside of the water storage box, making it difficult for the impurities and dirt to have a greater impact on the water quality of the water storage box, and thus enabling the water sprayed from the water spray nozzle to have a better maintenance effect on the concrete slab.

[0012] Preferably, a pair of first chutes are provided on the top surface of the base, respectively located on both sides of the water leakage port; the support mechanism includes a pair of sliding plates respectively slidably connected in the pair of first chutes; a second motor is installed on the outer side wall of the sliding plate away from the water leakage port; the output end of the second motor is fixedly connected with a second rotating shaft; the end of the second rotating shaft away from the second motor is fixedly connected with a connecting plate; the end of the connecting plate away from the second rotating shaft is fixedly connected with a plurality of support rods capable of supporting the concrete slab; a pushing assembly capable of pushing the sliding plate to slide along the first chute is arranged in the pair of first chutes.

[0013] By adopting the above technical solution, the concrete slab is lifted onto the base, and the pushing assembly is used to push the sliding plate to slide along the first chute towards the direction close to the water leakage port, so that the support rods are inserted into the round holes at both ends of the concrete slab to support the concrete slab. When the water spray nozzle sprays water to cure the concrete slab, the second motor is started to drive the second rotating shaft and the connecting plate to rotate, thereby driving the concrete slab to rotate slowly, which is convenient to realize the uniform water spraying curing work on the periphery of the concrete slab.

[0014] Preferably, first threaded through holes are provided on the inner side walls of the pair of first chutes away from the water leakage port; the pushing assembly includes a first threaded rod; the first threaded rod is threadedly connected in the first threaded hole, and the end of the first threaded rod close to the sliding plate contacts the side wall of the sliding plate away from the water leakage port; a first spring is connected to the side wall of the sliding plate away from the water leakage port; the end of the first spring away from the sliding plate is connected to the inner side wall of the first chute.

[0017] By adopting the above technical solution, when the scraper cleans the dirt and impurities adhered to the inner side wall of the bottom end of the water storage box, the dirt and impurities are easily adhered to the outer surface of the scraper. The driving component arranged on the water storage box pushes the straight plate in the cavity to slide and stretch the second spring. During the sliding process of the straight plate, the push rod is driven to extend out of the first through hole, prompting the larger impurities adhered to the scraper to fall off, facilitating the scraper to better clean the dirt and impurities.

[0018] Preferably, the driving component includes a concave shell; the concave shell is fixedly connected to the outer side wall of the water storage box close to the belt, and an airbag is arranged on the inner side wall of the bottom end of the concave shell; a pressing plate slidably matched with the inner side wall of the concave shell is arranged on the top of the airbag; the bottom surface of the pressing plate is connected with a third spring; the end of the third spring far away from the pressing plate is connected with the inner side wall of the bottom end of the concave shell; an arc surface is arranged on the top surface of the pressing plate; a cam capable of pushing the pressing plate to slide down is fixedly connected to the outer side wall of the first rotating shaft extending to the outside of the water storage box; an air pipe is fixedly connected to the airbag; the end of the air pipe far away from the airbag is communicated with the inside of the cavity.

[0019] By adopting the above technical solution, during the rotation of the first rotating shaft, the cam is driven to rotate. When the cam rotates to contact the arc surface on the top surface of the pressing plate, the cam pushes the pressing plate to slide down and compress the airbag through the cooperation of the cam and the arc surface. After the airbag is pressed, the gas inside it enters the cavity through the air pipe, thereby driving the straight plate to slide; when the cam loses contact with the pressing plate, the pressing plate slides back to the initial position under the elastic force of the third spring, facilitating the cam to reciprocally press the pressing plate.

[0022] Preferably, a sealing groove is arranged on the inner side wall of the first through hole; a sealing ring is fixedly connected to the inner side wall of the sealing groove.

[0023] By adopting the above technical solution, the sealing ring arranged in the sealing groove enables the inside of the cavity to have good sealing performance, reducing the possibility of the water in the water storage box entering the inside of the cavity.

[0024] Preferably, a discharge port is arranged on the inner side wall of the bottom end of the first cavity; a discharge pipe is fixedly connected to the inner side wall of the discharge port; a valve is arranged on the discharge pipe.

[0026] In summary, the present application has the following beneficial effects:

[0027] 1. Lift the concrete slab to the top of the water leakage port, rotate the first threaded rod so that the first threaded rod pushes the sliding plate to slide towards the direction close to the water leakage port, and make the support rod embed into the round holes at both ends of the concrete slab to realize the support of the concrete slab; then start the water pump to convey the water in the water storage box to the water pipe, and the water in the water pipe is sprayed on the concrete slab through the spray nozzle, so as to realize the water spraying and curing work of the concrete slab; the water sprayed from the spray nozzle and falling outside the concrete slab and flowing down from the concrete slab fall back into the water storage box through the water leakage port and are collected, realizing the recycling of water resources and reducing the waste of water resources;

[0029] 3. The filter screen filters the water falling back into the water storage box. By starting the first motor to drive the first lead screw to rotate, the cleaning brush cleans the filter screen, reducing the possibility of the mesh holes of the filter screen being blocked by impurities and dirt; during the rotation of the first lead screw, the second lead screw is driven to rotate, so that the scraper cleans the dirt and impurities adhered to the bottom of the water storage box, promoting the impurities to be discharged from the water storage box through the discharge pipe, reducing the possibility of impurities and dirt affecting the water quality, making the water sprayed from the spray nozzle not easily contain more impurities and dirt, and reducing the impact of water quality on the curing work of the concrete slab.

Through the cooperation of the cam 85 and the arc surface 831, the pressing plate 83 slides down to squeeze the airbag 82. The gas inside the airbag 82 enters the pair of cavities 71 respectively through the air pipe 821 and the U-shaped tube 86, and then pushes the straight plate 72 to slide; when the cam 85 loses contact with the pressing plate 83, the pressing plate 83 slides back to the initial position under the elastic force of the third spring 84, which is convenient for the cam 85 to reciprocally squeeze the pressing plate 83.

[0055] Working principle: When curing the concrete slab, lift the concrete slab to the top of the water leakage port 11, rotate the first threaded rod 551 so that the first threaded rod 551 pushes the sliding plate 51 to slide towards the direction close to the water leakage port 11, thereby enabling the support rod 54 to be embedded into the round holes at both ends of the concrete slab to achieve the support of the concrete slab;

[0056] Then start the water pump 4 to convey the water in the water storage box 3 into the water delivery pipe 21. The water in the water delivery pipe 21 is sprayed onto the concrete slab through the spray nozzles 22, thereby realizing the spraying and curing work of the concrete slab; The water sprayed from the spray nozzles 22 and falling outside the concrete slab and flowing down from the concrete slab falls back into the water storage box 3 through the water leakage port 11 and is collected, thereby realizing the recycling of water resources and reducing the waste of water resources; During the spraying process of the spray nozzles 22, start the second motor 52 and the second motor 52. The second motor 52 drives the second rotating shaft 521 and the connecting plate 53 to rotate, and then drives the concrete slab to rotate slowly. The third motor 14 drives the third threaded rod 15 to rotate. During the rotation of the third threaded rod 15, the support frame 2 is driven to slide along the second sliding groove 13. Through the coordinated work of the second motor 52 and the third motor 14, the spray nozzles 22 can evenly spray water on the outside of the concrete slab, reducing the possibility of damage to the concrete slab caused by uneven spraying;

[0057] The water falling back into the water storage box 3 from the surface of the concrete slab will be filtered by the filter screen 61 before entering the water inlet pipe 41, so that the water sprayed from the spray nozzles 22 is not likely to contain a large amount of impurities and dirt, reducing the impact of water quality on the curing work of the concrete slab; After the filter screen 61 is used for a long time, dust and impurities are likely to adhere to the filter screen 61. Start the first motor 33 to drive the first threaded rod 34 to rotate. During the rotation of the first threaded rod 34, the fixing plate 341 and the cleaning brush 342 are driven to slide, so that the cleaning brush 342 cleans the filter screen 61, reducing the possibility of the mesh holes of the filter screen 61 being blocked by impurities and dirt; During the rotation of the first threaded rod 34, the first bevel gear 312 is driven to rotate. Through the coordinated work of the first bevel gear 312 and the second bevel gear 343 and the transmission of the first belt pulley 313, the second belt pulley 315 and the belt 316, the second threaded rod 314 rotates, so that the scraper 7 cleans the dirt and impurities adhered to the bottom of the water storage box 3, prompting the impurities to be discharged from the water storage box 3 through the discharge pipe 36, reducing the possibility of impurities and dirt affecting the water quality;

[0058] During the rotation of the first rotating shaft 311, the cam 85 is driven to squeeze the pressing plate 83 to slide downward to squeeze the airbag 82. The gas inside the airbag 82 enters the cavity 71 through the U-shaped tube 86 to push the straight plate 72 to slide. During the sliding process of the straight plate 72, the push rod 75 is driven to extend out of the first through hole 74, prompting the larger impurities adhered to the scraper 7 to fall off, facilitating the scraper 7 to better clean dirt and impurities. The sealing ring 742 provided in the sealing groove 741 enables the inside of the cavity 71 to have good sealing performance, reducing the possibility of the water in the water storage box 3 entering the inside of the cavity 71.

[0059] The above are all the preferred embodiments of this application. The protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
