Detailed Implementation

[0026] To better understand the purpose, structure, and function of this utility model, the following detailed description, in conjunction with the accompanying drawings, provides a curing device for concrete in winter, so that those skilled in the art can better understand and implement this utility model. However, the embodiments described are not intended to limit this utility model.

[0027] Please see Figures 1 to 6As shown, this embodiment provides a curing device for concrete in winter, including a movable support base 100 and a curing component 200 located above the movable support base 100; four sets of lifting components 300 are arranged on the movable support base 100, and the four sets of lifting components 300 are distributed side by side on both sides of the upper end of the movable support base 100; the curing component 200 includes a mounting frame 210, a spraying component 220 and a heat insulation component 230; the mounting frame 210 is connected to the four sets of lifting components 300 and can be positioned relative to the movable support base 100. The movable support 100 moves up and down; the spraying assembly 220 is slidably connected to the upper end of the mounting frame 210 and can move back and forth relative to the mounting frame; the insulation assembly 230 includes a fixing frame 231 and an insulation cloth 232; the fixing frame 231 is connected to the bottom of the mounting frame 210 and is arranged parallel to the mounting frame 210, and a winding shaft 233 is rotatably connected to one end of the fixing frame 231; one end of the insulation cloth 232 is connected to the winding shaft 233, and the other end extends to the end of the fixing frame 231 away from the winding shaft 233. The movable support 100 includes a base 110 and several sets of pulleys 120; the base 110 has a hollow structure, and the several sets of pulleys 120 are evenly distributed on the bottom of the left and right side plates of the base 110. Each lifting assembly 300 includes a lifting rod 310 and a hydraulic cylinder 320 for driving the lifting rod 310 to move up and down relative to the base 110; the upper end of the lifting rod 310 is connected to the bottom of the mounting frame 210, and the lower end of the lifting rod 310 is connected to the hydraulic cylinder 320; two second mounting slots 111 are respectively provided at the upper ends of the left and right side plates of the base 110, and the hydraulic cylinder 320 is assembled in the second mounting slots 111.

[0028] Because a movable support base 100 and a curing component 200 are provided, and a lifting component 300 is provided on the movable support base, the curing component 200 includes an installation frame 210, a spraying component 220 and a thermal insulation component 230. The thermal insulation component 230 is provided with a fixing frame 231, a winding shaft 233 and thermal insulation cloth 232. Through the coordinated use of the above components, not only can the 500-meter section of concrete to be cured be sprayed and cured evenly, ensuring that the concrete surface is always in a moist state and enhancing the curing effect of the concrete, but it can also effectively prevent the water flow from directly impacting the concrete surface during the spraying process and causing damage to the concrete surface, ensuring the curing quality of the concrete and greatly reducing the quality risk of concrete construction in winter.

[0029] Specifically, a movable support base 100 is provided to quickly move the winter concrete curing device to the concrete section 500 to be cured, facilitating curing and improving construction efficiency. Four sets of lifting components 300 are provided to securely move the mounting frame 210 up and down relative to the movable support base 100, and to move the fixing frame 231, fixed below the mounting frame 210, up and down relative to the support base. This allows the insulation cloth 232 to cover the surface of the concrete section 500 to be cured, or to move it away from the surface, facilitating its movement to the next concrete section 500 to be cured. A spraying component 220 is provided and can move back and forth relative to the mounting frame to evenly spray constant-temperature water onto the surface of the concrete section 500, thus achieving curing. By using insulating cloth 232 to cover the surface of the concrete 500 to be cured, it absorbs the constant-temperature water sprayed by the spraying component 220. This not only keeps the constant-temperature water warm and maintains the moisture on the surface of the concrete 500, but also prevents the water flow from directly impacting the concrete surface and causing damage, thus ensuring the curing quality of the concrete and reducing the risk of poor concrete construction quality in winter. A retractable shaft 233 facilitates the opening and closing of the insulating cloth 232, reducing manual operation difficulty and improving construction efficiency.

[0030] Preferably, the upper surfaces of both sides of the mounting frame 210 are respectively provided with a first sliding groove 211 and a first mounting groove 212; the first sliding groove 211 is located on one side of the first mounting groove 212, and a lead screw 213 is rotatably connected in the first sliding groove 211; a first drive motor 214 is installed in the first mounting groove 212, and the output end of the first drive motor 214 is connected to the lead screw 213; the spraying assembly 220 includes a spray plate 221 and a constant temperature water tank 222, the constant temperature water tank 222 is mounted on the movable support 100 and communicates with the spray plate 221; both ends of the spray plate 221 are respectively located in the first sliding groove 211 and are respectively threadedly connected to the two lead screws 213, and can slide along the first sliding groove 211. The constant temperature water tank 222 and the spray plate 221 are connected by a conduit (not shown in the figure), and a valve is provided on the conduit. The constant temperature water tank 222 is equipped with an electric heating tube and a temperature sensor for monitoring the water temperature. The electric heating tube heats the water inside the constant temperature water tank 222, and the temperature sensor monitors the water temperature so that when the water temperature exceeds the set value, the electric heating tube can be controlled to stop heating, thereby supplying constant temperature water, reducing temperature difference, and reducing impact stress on the concrete surface.

[0031] Because the mounting frame 210 is equipped with a first sliding groove 211 and a first mounting groove 212, and the spraying assembly 220 is equipped with a water spray plate 221 and a constant temperature water tank 222, and the first sliding groove 211 is rotatably connected to a lead screw 213, and the first mounting groove 212 is equipped with a first drive motor 214, the water spray plate 221 can move left and right relative to the first sliding groove 211 through the cooperation of the above components, ensuring that the water spray plate 221 sprays the concrete surface evenly. Specifically, when the first drive motor 214 is started, the output end of the first drive motor 214 drives the lead screw 213 to rotate. Since both ends of the water spray plate 221 are threadedly connected to the lead screw 213, under the rotation of the lead screw 213, the water spray plate 221 can move back and forth smoothly and at a uniform speed in the first sliding groove 211. Compared with manual spraying, this greatly improves the accuracy and efficiency of spraying, ensuring that all parts of the concrete to be cured receive sufficient curing.

[0032] Preferably, a handle 233A is provided at one end of the winding shaft 233. Because of the handle 233A, construction workers can easily wind or unwind the insulation cloth 232 by simply turning the handle 233A. When it is necessary to quickly cover the concrete surface for moist insulation, construction workers can quickly turn the handle 233A to unwind the insulation cloth 232, improving work efficiency. After the concrete curing is completed, the insulation cloth 232 can also be easily rolled up for storage and future use. Furthermore, after the insulation cloth 232 is unwinding, to ensure its flatness, both sides of the insulation cloth 232 can be fixed to the side walls of the fixing frame 231.

[0033] Preferably, the winter concrete curing device also includes a heated shed 400 erected on a movable support base 100. The heated shed 400 effectively blocks the intrusion of cold air or snowflakes, reducing heat loss and stabilizing the temperature around the concrete. This further enhances the overall insulation performance of the winter concrete curing device, ensuring the concrete undergoes cement hydration in a suitable temperature environment, significantly reducing the risk of frost damage, and improving the concrete's strength and durability. Furthermore, the heated shed 400 is detachably mounted on the movable support base 100, facilitating assembly and disassembly, and can be moved with the support base 100. This allows the heated shed 400 to be easily moved to different concrete construction areas, accelerating the curing process while reducing the number of times the heated shed 400 needs to be re-erected, thus lowering curing costs.

[0034] Preferably, a heating element 410 is installed on the top of the heated enclosure 400. Because the heated enclosure 400 is equipped with a heating element 410, the overall temperature inside the heated enclosure 400 can be effectively maintained, providing a more stable and suitable curing temperature environment for the concrete.

[0035] The working principle of a winter concrete curing device provided in this embodiment is as follows:

[0036] When it is necessary to cure the concrete section 500 to be cured, the curing device for winter concrete is moved to the designated area by the movable support 100 driven by the tractor. Then, the handle 233A is turned to unfold the insulation cloth 232, and the end of the insulation cloth 232 away from the winding shaft 233 is fixed to the end of the fixing frame 231 away from the winding shaft 233. The height of the lifting rod 310 is lowered, so that the installation frame 210 is lowered, thereby driving the fixing frame 231 fixed below the installation frame 210 to move towards the surface of the concrete section 500 to be cured until the insulation cloth 232 covers the surface of the concrete section 500 to be cured. Open the valve between the constant temperature water tank 222 and the sprinkler plate 221 to spray constant temperature water onto the concrete surface through the sprinkler plate 221. Start the first drive motor 214, which drives the lead screw 213 to rotate. Under the rotation of the lead screw 213, the sprinkler plate 221 slides smoothly and at a uniform speed within the first slide groove 211, thereby changing the spraying position of the sprinkler plate 221 on the concrete surface. The insulation cloth 232 absorbs the constant temperature water sprayed from the sprinkler plate 221 and keeps the concrete surface warm and moist, thus achieving concrete curing. After the concrete has cured, close the valve between the constant temperature water tank 222 and the water spray plate 221, raise the height of the lifting rod 310 to raise the installation frame 210, thereby driving the fixing frame 231 to move away from the surface of the cured concrete until the insulation cloth 232 is detached from the surface of the cured concrete. Then, release the fixing between the insulation cloth 232 and the fixing frame 231, and turn the handle 233A to roll up the insulation cloth 232 for the next use.

[0037] It is understood that this utility model has been described through some embodiments, and those skilled in the art will recognize that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of this utility model. Furthermore, under the teachings of this utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of this utility model.
