[0037] An embodiment of the utility model provides a concrete structure curing device, which realizes the watering curing process of the concrete structure through automated equipment, avoiding the problem of large labor intensity in manual watering curing.

[0038] See Figures 1 to 4 As shown in, the concrete structure curing device provided by the embodiment of the utility model includes a support main body 10, a spraying assembly 20, a lifting assembly 30 and a moving assembly 40. Among them, the spraying assembly 20 is arranged on the support main body 10. The spraying assembly 20 includes a spraying pipe 21 and a water supply part 22. The water supply part 22 is connected to the spraying pipe 21. A plurality of spraying holes are formed on the outer surface of the spraying pipe 21. The lifting assembly 30 is arranged on the support main body 10. The lifting assembly 30 includes a lifting rod 31 and a driving mechanism 32. The top of the lifting rod 31 is connected to the spraying pipe 21, and the bottom of the lifting rod 31 is connected to the driving mechanism 32. The driving mechanism 32 can drive the lifting rod 31 to move along its own axis; the moving assembly 40 is arranged at the bottom of the support main body 10, and the moving assembly 40 can drive the support main body 10 to move along the horizontal plane.

[0039] During use, the support main body 10 is moved to the required position through the moving assembly 40, so that the spraying holes are directly opposite to the concrete structure. The spraying pipe 21 is supplied with water through the water supply part 22. The water flow passes through the spraying pipe 21 and sprays out from the spraying holes, thereby spraying on the concrete structure. By driving the lifting rod 31 to move along its own axis through the driving mechanism 32, the connected spraying pipe 21 can be driven to move synchronously. The height position of the spraying pipe 21 can be adjusted at any time, so as to spray different positions of the concrete structure. Moreover, the driving mechanism 32 can drive the spraying pipe 21 to move up and down reciprocally to realize uniform spraying of the concrete structure. Through the cooperation of the moving assembly 40 and the lifting assembly 30, the movement of the spraying pipe 21 in the horizontal and vertical directions can be realized, ensuring full coverage and uniform spraying of the surface of the concrete structure, avoiding local drying or over-wetting phenomena during the curing process, and improving the strength and surface quality of the concrete structure. And, according to different concrete structures and curing requirements, the height and position of the spraying pipe 21 can be adjusted, improving the adaptability of the device. In addition, the spraying assembly 20 can accurately control the spraying amount and spraying range of water, avoiding waste of water resources. Through the coordinated cooperation among the spraying assembly 20, the lifting assembly 30 and the moving assembly 40, the utility model reduces the need for manual operation, reduces the labor intensity and labor cost during the curing process, and improves the curing efficiency; and can accurately and uniformly control the spraying amount and spraying range of water, having a better curing effect.

[0040] Regarding the spray component 20. Specifically, an inner support guide ring 11 is provided on the support main body 10. The inner support guide ring 11 extends in a semicircular shape. The inner support guide ring 11 and the support main body 10 enclose a receiving space. The driving mechanism 32 is arranged in the receiving space. A plurality of guide holes 111 are formed through the inner support guide ring 11. The guide holes 111 are arranged along the extending direction of the inner support guide ring 11. A lifting rod 31 is inserted through each guide hole 111. The setting of the inner support guide ring 11 provides stable guidance and support for the lifting rod 31, ensuring the stable movement track of the lifting rod 31, making the spray pipe 21 more stable during the lifting process, and reducing shaking and unstable factors. Arranging the driving mechanism 32 in the receiving space can reduce the influence of the external environment on it and extend the service life of the driving mechanism 32.

[0041] Among them, the guide holes 111 are evenly spaced along the extending direction of the inner support guide ring 11, so that the lifting rods 31 are evenly distributed, improving the stability of the support process for the spray pipe 21. The number of the guide holes 111 is not limited here and can be selected according to the actual working conditions and requirements. The shape of the inner support guide ring 11 can also be set as a rectangle, a triangle, etc. in other embodiments and is not limited here.

[0042] Specifically, a positioning support ring 12 is provided on the support main body 10. The positioning support ring 12 extends in a semicircular shape and has a radius larger than that of the inner support guide ring 11. Corresponding to each guide hole 111, a positioning hole is formed through the positioning support ring 12. Each lifting rod 31 is sequentially inserted through the positioning hole and the guide hole 111. Through the double guidance of the positioning support ring 12 and the inner support guide ring 11, the lifting rod 31 is more stable during the lifting process, reducing shaking and deviation, thereby improving the accuracy and uniformity of spraying. In addition, the setting of the positioning support ring 12 increases the structural strength of the support main body 10, enabling it to better bear the loads applied by the spray component 20 and the lifting component 30, and improving the reliability and durability of the device.

[0043] Furthermore, an auxiliary ladder 122 is provided on the positioning support ring 12. The auxiliary ladder 122 extends along the extending direction of the positioning support ring 12. The setting of the auxiliary ladder 122 enables the operator to conveniently climb to the position of the positioning support ring 12 to maintain and repair the spray component 20, the lifting component 30, etc., improving the work efficiency and reducing the maintenance difficulty.

[0044] Regarding the driving mechanism 32. The driving mechanism 32 includes a moving part and a movable block 321. The accommodating space is conical, and the movable block 321 is arranged in a conical shape adapted to the accommodating space. The movable block 321 is inserted and slidably connected to the accommodating space. The moving part can drive the movable block 321 to move along its own axis. Corresponding to each lifting rod 31, a guiding groove 322 is arranged on the outer surface of the movable block 321. The guiding groove 322 extends along the axial direction of the movable block 321. A sliding block 311 is arranged at the bottom of the lifting rod 31, and the sliding block 311 is slidably connected to the guiding groove 322.

[0045] Herein, it is defined that one end of the guiding groove 322 close to the vertex of the movable block 321 is the first end 301, and one end of the guiding groove 322 close to the bottom surface of the movable block 321 is the second end 302. The outer surface of the movable block 321 slopes downward from the second end 302 to the first end 301. When the sliding block 311 is at the first end 301 of the guiding groove 322, the lifting rod 31 is in the lowest position. When it is necessary to increase the height of the lifting rod 31, the moving part drives the movable block 321 to move into the accommodating space (that is, the movable block 321 moves along its own axis from the second end 302 to the first end 301), so that a relative displacement is generated between the sliding block 311 and the guiding groove 322. Due to the limiting effect of the guiding hole 111 and the positioning hole, the lifting rod 31 cannot move in the horizontal direction. Therefore, when the movable block 321 moves into the accommodating space, through the movement of the guiding groove 322, the sliding block 311 generates a relative movement in the guiding groove 322 from the first end 301 to the second end 302. Due to the inclined setting of the outer surface of the movable block 321, when the sliding block 311 moves in the guiding groove 322 from the first end 301 to the second end 302, under the support of the movable block 321, the height of the sliding block 311 gradually increases, thereby driving the height of the lifting rod 31 connected thereto to gradually increase, and finally realizing the process of increasing the height of the spray pipe 21. When it is necessary to reduce the height of the lifting rod 31, it is only necessary to drive the movable block 321 to move out of the accommodating space through the moving part. The specific principle is the same as the above content and will not be elaborated here.

[0046] In this embodiment, since there are multiple lifting rods 31, a plurality of guiding grooves 322 are arranged at intervals along the circumferential direction of the outer surface of the movable block 321, so as to be connected to the sliding blocks 311 of the corresponding lifting rods 31. The movable block 321 is conically arranged. Due to the geometric characteristics of a circle, the distance between the center of each vertical section of the movable block 321 and any point on the outer surface is equal. Therefore, through this setting, it can be ensured that no matter how the movable block 321 moves, each lifting rod 31 connected thereto can be lifted synchronously and by the same height, thereby improving the stability and coordination during the lifting process of the lifting rod 31.

[0047] Furthermore, the moving part includes a fixing plate 323 and a hydraulic telescopic rod 324. The fixing plate 323 faces the accommodating space and is fixedly connected to the supporting body 10. The hydraulic telescopic rod 324 is arranged on the fixing plate 323, and the telescopic end of the hydraulic telescopic rod 324 is connected to the movable block 321. The fixing plate 323 facing the accommodating space and being fixedly connected to the supporting body 10 ensures the stability and reliability of the moving part, provides effective support for the hydraulic telescopic rod 324. The hydraulic telescopic rod 324 can precisely control the moving distance of the telescopic end by controlling the flow rate and pressure of the hydraulic oil, and further precisely control the moving distance of the movable block 321, so as to precisely control the lifting height of the lifting rod 31. It can be understood that the hydraulic telescopic rod 324 is an existing mechanical device in the art, and its working principle and specific structure will not be elaborated here.

[0048] In other embodiments, the moving part can also be devices such as a cylinder or a lead screw nut pair, as long as it can ensure the reciprocating movement of the movable block 321 in the accommodating space. Its specific form is not limited here.

[0049] To improve the connection stability between the spray pipe 21 and the lifting rod 31, a limiting hoop 312 is provided at the end of the lifting rod 31. The limiting hoop 312 is designed as a three-quarter cylindrical shape, and the spray pipe 21 is inserted through the limiting hoop 312. After the unfilled spray pipe 21 is inserted through the limiting hoop 312, the spray pipe 21 is filled with water, so that the spray pipe 21 expands and is clamped inside the limiting hoop 312. When the lifting rod 31 is adjusted to different heights, the length of the spray pipe 21 can be adjusted by stretching the end of the spray pipe 21. By providing the limiting hoop 312, the movement of the spray pipe 21 on the lifting rod 31 can be effectively restricted, preventing the spray pipe 21 from shaking or falling off during the lifting process, and improving the connection stability between the spray pipe 21 and the lifting rod 31. The three-quarter cylindrical design of the limiting hoop 312 can not only firmly limit the spray pipe 21 inside the limiting hoop 312 after the spray pipe 21 is filled with water, but also prevent the spray pipe 21 from being deformed or even broken due to excessive pressure of the limiting hoop 312, ensuring the stability of the spray pipe 21 placed inside the limiting hoop 312.

[0050] During use, in addition to adjusting the position of the spray pipe 21 in the vertical direction through the lifting rod 31, it is also necessary to adjust the position of the spray pipe 21 in the horizontal direction through the moving assembly 40. The moving assembly 40 includes a base 41 and moving wheels 42. The base 41 is arranged on the bottom side of the supporting body 10, and a moving wheel 42 is provided at each of the four corners of the base 41, so as to facilitate the operator to push the maintenance device to move horizontally.

[0051] Furthermore, two guide rods 13 are fixedly connected to the side wall of the support body 10, and a guide wheel 14 is provided at the end of each guide rod 13. In the process of spraying and curing the concrete structure, when the support body 10 needs to be moved horizontally, the guide wheels 14 on the guide rods 13 can slide against the concrete structure to achieve parallel sliding of the support body 10 and the concrete structure. The design of the guide rods 13 and the guide wheels 14 reduces the friction between the support body 10 and the concrete structure, so that the support body 10 can slide more easily.

[0052] Regarding the water supply part 22, the water supply part 22 includes a water tank 221 and a water storage nozzle 222. The water inlet end of the water storage nozzle 222 is connected to the water tank 221, and the water outlet end of the water storage nozzle 222 is connected to the spray pipe 21. The water tank 221 can store a certain amount of water to provide a stable water source for the spray pipe 21, ensuring that the maintenance process of the concrete structure will not be interrupted due to insufficient water source. The water storage nozzle 222 can evenly input the water in the water tank 221 into the spray pipe 21, and then evenly spray the water onto the surface of the concrete structure through the spray pipe 21, thereby achieving uniform spraying and improving the maintenance effect. In addition, the water storage nozzle 222 can control the flow and pressure of water, avoid water waste, and save water costs. It is understandable that a water inlet is provided on the water tank 221 so that water can be added to the water tank 221 at any time; a power pump is provided on the water storage nozzle 222 so that water can be pumped into the spray pipe 21 through the water storage nozzle 222. The water storage nozzle 222 is a common mechanical device in the art, and its working principle and specific structure are not described in detail here.

[0053] Furthermore, an auxiliary support rod 15 is provided on the side wall of the support body 10, and an auxiliary support plate 16 is provided at the end of the auxiliary support rod 15. The auxiliary support plate 16 extends in an arc shape and faces the spray pipe 21. The connection between the spray pipe 21 and the water storage nozzle 222 can be placed on the auxiliary support plate 16. The arc shape of the auxiliary support plate 16 can form a support and positioning for the connection between the spray pipe 21 and the water storage nozzle 222, so as to improve the anti-drooping effect of the connection between the spray pipe 21 and the water storage nozzle 222. The arc shape of the auxiliary support plate 16 can better fit the connection between the spray pipe 21 and the water storage nozzle 222, provide more stable support, and reduce the shaking and drooping risks of the connection. Through the support and positioning of the auxiliary support plate 16, the connection between the spray pipe 21 and the water storage nozzle 222 can be prevented from being pulled or twisted due to gravity or external force, reducing the possibility of damage to the connection and extending the service life of the equipment.
