Description

Technical Field

[0001] The present invention relates to the technical field of concrete curing, and particularly relates to a curing device for concrete components. Background Art

[0002] In the fields of construction engineering, bridge construction, and municipal facilities, concrete components (concrete members) have become indispensable basic materials for engineering construction due to their high strength, good durability, and plasticity. Their performance and quality are directly related to the overall safety, durability, and service life of the project. As a core link in ensuring quality, the curing of concrete components plays a decisive role in the process of cement hydration reaction. Scientific and reasonable curing can effectively promote the full hydration of cement, improve the strength of concrete components, and reduce quality defects such as cracks and shrinkage.

[0003] Currently, most curing devices for concrete components adopt a curing chamber structure. A partition is fixedly connected inside the curing chamber, which divides the curing chamber into a curing area and a collection area. A spraying unit is provided in the curing area for spraying water to cure the concrete components. A number of water-permeable holes are opened on the partition, and the excess curing water can flow into the collection area through the water-permeable holes. However, this technical solution has obvious drawbacks: during the curing process, concrete residues are likely to fall off the surface of the concrete components, and these residues are extremely easy to block the water-permeable holes, resulting in the retention of excess curing water on the partition. On the one hand, the humidity at the bottom of the curing area increases significantly, forming a significant humidity gradient with the upper and middle spaces, destroying the uniformity of the curing environment, and causing differences in the cement hydration reaction rates of different parts of the concrete components, affecting the uniformity of the overall strength. On the other hand, the surface of the concrete components in the water accumulation area is prone to apparent defects such as "efflorescence" and "sandiness" due to excessive water penetration. This not only reduces the aesthetic appearance of the components but also weakens their bonding strength with subsequent decorative construction such as plastering and tiling, posing a potential threat to the project quality. Summary of the Invention

[0004] The present invention aims to provide a curing device for concrete components to solve the problems caused by the blockage of water-permeable holes by concrete residues in the existing curing chamber structure, resulting in the retention of excess curing water, and further causing uneven curing environment, inconsistent strength of concrete components, and apparent defects.

[0005] To achieve the above object, the present invention adopts the following technical solution: a concrete component curing device, which includes a curing chamber, a partition is fixedly connected in the curing chamber, and the partition divides the curing chamber into a curing area and a collection area; a positioning unit and a lifting spraying unit are provided in the curing area, the positioning unit is used for vertically positioning the concrete component, and the lifting spraying unit can lift and lower between adjacent concrete components and contact the side surface of the concrete component to spray water for curing the concrete component; vibration marking units are provided on the partitions on both sides of each concrete component, and each vibration marking unit includes a connecting plate, a first elastic member and a moving part, a receiving groove is provided on the partition, the connecting plate is installed in the receiving groove through the first elastic member, a plurality of water permeable holes are provided on the connecting plate, and the surplus curing water can flow into the collection area through the water permeable holes; the moving part can contact the side surface of the concrete component and can lift up the connecting plate without interfering with the lowering of the lifting spraying unit.

[0006] The beneficial effects of this solution are as follows: (1) High-efficiency anti-blocking: The present invention innovatively adopts the linkage mechanism of the lifting spraying unit and the vibration marking unit. During water spraying curing, the lifting spraying unit descends and presses the connecting plate, causing the first elastic member to contract and store energy. When the lifting spraying unit is separated from the connecting plate, the first elastic member resets and drives the connecting plate to vibrate, effectively shaking off the concrete residues blocked at the water permeable holes. Compared with traditional curing devices, the dredging efficiency of the water permeable holes is greatly improved. This effectively avoids the retention of surplus curing water on the connecting plate, prevents the abnormal increase of humidity at the bottom of the curing area due to water accumulation, maintains the humidity uniformity of the curing environment, ensures that the cement hydration reaction rates of all parts of the concrete component are consistent, and thus improves the uniformity of the overall strength of the concrete component.

[0007] (2) Precise problem identification: In construction projects, protrusions on the surface of concrete components have a significant impact on project quality. For decorative components with high appearance requirements, small protrusions damage the visual effect and reduce the building quality; for high-precision foundation concrete components, the protrusions result in insufficient surface precision and affect the use function; the protrusions of waterproof concrete components will damage the surface flatness, weaken the waterproof layer effect and increase the leakage risk.

[0008] In the collaborative operation of detection and curing, the positioning unit flexibly positions the concrete component through the limiting groove, which not only ensures its stable placement but also reserves the freedom of inclination. When the lifting spraying unit descends, if there are small protrusions on the surface of the concrete component, the lateral force generated by the descent of the lifting spraying unit will cause the concrete component to tilt, and then push the moving part to lift up the connecting plate, forming a visual defect mark.

[0009] This mechanism realizes the synchronous progress of curing and detection, can identify defective concrete components on the surface in real time without manual intervention, and significantly improves the detection efficiency. At the same time, the lifted connecting plate will not hinder the normal descent of the lifting spraying unit, ensuring the continuous progress of the curing operation, and does not affect the curing process of other concrete components and the automatic dredging function of the water permeable holes, guaranteeing the efficient and stable operation of the entire curing system.

[0010] (3) Improve the curing quality: For the curing problems caused by the hydration heat of cement, traditional top spraying is likely to cause uneven water temperatures between the upper and lower parts of concrete components. Coupled with the small gap between adjacent components and slow heat dissipation, the temperature difference is exacerbated, affecting the curing effect. In this solution, the lifting spraying unit can flexibly lift between adjacent concrete components, making the water temperature sprayed on each area of the concrete component uniform, effectively ensuring the uniform strength, shrinkage, and stress distribution of the concrete component after curing. At the same time, through anti-blocking design, the remaining curing water is prevented from staying, eliminating apparent defects such as "efflorescence" and "sandiness", improving the appearance quality of the concrete component and the bonding force of decorative construction, reducing the risk of decorative layer peeling, and is particularly suitable for engineering scenarios such as building decoration, high-precision instrument bases, and hydraulic components that have strict requirements for appearance, precision, and waterproofness.

[0011] (4) Compact and practical structure: The positioning unit, lifting spraying unit, and vibration marking unit cooperate closely. While realizing the functions of efficient curing and automatic detection, the overall structure design is compact and reasonable. The device does not require large-scale renovation of the curing room, is easy to install and maintain, effectively reduces equipment costs and construction difficulties, and has significant engineering application and promotion value.

[0012] Preferably, the lifting spraying unit includes a mounting plate. A first driving member is fixedly connected to the top of the mounting plate. A plurality of spraying parts are fixedly connected to the bottom of the mounting plate. The adjacent spraying parts are arranged at intervals, and the first driving member can drive the spraying parts to lift.

[0013] The beneficial effects of this solution are as follows: The lifting spraying unit adopts a structural design of a mounting plate combined with a first driving member and spaced spraying parts. By driving the spraying parts to lift with the first driving member, it can be applied to the curing of concrete components of different heights; at the same time, by driving the spraying parts to lift with the first driving member, it can ensure that the water temperature sprayed on each area of the concrete component is uniform, promote the balanced progress of the cement hydration reaction, and improve the curing effect and the quality of the concrete component.

[0014] Preferably, each spraying part includes a connecting rod and a spraying pipe. The spraying pipe is fixed to the bottom of the mounting plate through the connecting rod. The spraying pipe can contact the side surface of the concrete component. A plurality of first nozzles are arranged axially on the side of the spraying pipe close to the concrete component, and the first nozzles can spray the curing water onto the side surface of the concrete component.

[0015] The beneficial effects of this solution are as follows: Through the integrated design of the spraying part, the synergistic effect of curing and function triggering is realized. The spraying pipe is closely attached to the side surface of the concrete component. During the curing process, the surface protrusions can be detected synchronously. Once a lateral force is generated when encountering a protrusion and the concrete component tilts, the vibration marking unit can be triggered to mark; the axially arranged first nozzles ensure that the curing water fully covers the side surface of the concrete component, improving the curing uniformity. This design takes into account the functions of detection, curing, and dredging, not only ensuring the curing quality but also enhancing the reliability and practicality of the curing device.

[0016] Preferably, a plurality of pressing rods are fixedly connected to the bottom of the spraying pipe, and the pressing rods can press the connecting plate.

[0017] The beneficial effect of this solution is that the bottom pressing rods are precisely linked with the vibration marking unit. When the spraying pipe descends, the connecting plate is pressed to compress and store energy in the first elastic member. After separation, the elastic reset drives the connecting plate to vibrate, effectively removing the blockage in the water permeable holes.

[0018] Preferably, the positioning unit includes a second driving member and a positioning plate. The second driving member is fixedly connected to the side wall of the curing chamber. The positioning plate is arranged inside the curing chamber and fixedly connected to the output shaft of the second driving member. The second driving member can drive the positioning plate to move. A plurality of first limiting grooves are provided on the positioning plate, and a plurality of second limiting grooves are provided on the inner side wall of the curing chamber. The first limiting grooves and the second limiting grooves correspond to each other one by one.

[0019] The beneficial effect of this solution is that the precise positioning and flexible detection of concrete components are realized through the positioning unit. The second driving member drives the positioning plate to move, and the position of the concrete component can be quickly adjusted, so that both ends of the concrete component are respectively inserted into the first limiting groove and the second limiting groove, ensuring the orderly progress of the curing operation. At the same time, the first limiting groove and the second limiting groove are correspondingly arranged and do not completely clamp the concrete component, which not only maintains its basic stability but also allows the concrete component to tilt under the action of external force, creating conditions for detecting surface protrusions subsequently. When the lifting spraying unit encounters a lateral force due to a surface protrusion on the concrete component, the concrete component can tilt smoothly to trigger the detection mechanism, realizing automatic defect marking, ensuring the coordinated and efficient operation of the curing and detection functions, and enhancing the practicability and reliability of the curing device.

[0020] Preferably, the widths of both the second limiting groove and the first limiting groove are greater than the thickness of the concrete component. A plurality of second nozzles are installed at both ends of the spraying pipe, and the second nozzles can spray water onto both ends of the concrete component.

[0021] The beneficial effect of this solution is that the curing effect is significantly improved by optimizing the limiting groove and the spraying structure. The widths of both the second limiting groove and the first limiting groove are greater than the thickness of the concrete component, forming a gap between the concrete component and the groove wall after installation. Combined with the second nozzles at both ends of the spraying pipe, the curing water can be accurately sprayed onto the ends of the concrete component, effectively covering the edge areas that are easily missed in traditional curing, eliminating the curing blind spots, realizing the all-round and uniform curing of the surface of the concrete component, ensuring the full hydration reaction of cement in each part of the component, and enhancing the overall strength and durability.

[0022] Preferably, the moving part includes a grinding rod. There is a first installation groove on the partition board. A guiding hole is provided on the partition board above the first installation groove. The guiding hole communicates with the first installation groove. The lower end of the grinding rod is slidably arranged in the first installation groove. The upper end of the grinding rod extends out of the guiding hole and is located above the partition board. There is a second installation groove on the connecting plate. The open ends of the first installation groove and the second installation groove are arranged opposite to each other. The connecting plate is also provided with a through hole penetrating the second installation groove. The pressing rod can pass through the through hole. A first wedge-shaped block is fixedly connected to the side of the grinding rod close to the connecting plate. A baffle is fixedly connected to the side of the first wedge-shaped block away from the grinding rod. A waist-shaped hole is provided on the baffle and the first wedge-shaped block. The pressing rod can pass through the waist-shaped hole. The baffle on the side of the waist-shaped hole away from the first wedge-shaped block is a shielding part, and the shielding part can shield the through hole.

[0023] The beneficial effects of this solution are as follows: Through the ingenious cooperation of the grinding rod with the wedge-shaped block and the baffle, this solution realizes precise detection and functional linkage. The grinding rod slides stably under the constraint of the first installation groove and the guiding hole, ensuring the accuracy of force transmission. The first wedge-shaped block is adapted to the second wedge-shaped block on the connecting plate. When the concrete member tilts and pushes the grinding rod, the connecting plate can be quickly lifted to mark the defect. At the same time, the design of the waist-shaped hole and the shielding part on the baffle enables the pressing rod to trigger the vibration of the connecting plate to dredge the water-permeable hole through the shielding part during the descent of the spraying pipe, and can be aligned with the through hole through the waist-shaped hole during the defect detection of the concrete member, avoiding the obstruction of the pressing rod, ensuring that the maintenance operation and the detection function do not interfere with each other, and improving the overall operation reliability of the device.

[0024] Preferably, the side of the grinding rod close to the concrete member is a rough surface.

[0025] The beneficial effects of this solution are as follows: By setting the side of the grinding rod close to the concrete member as a rough surface, this technical solution constructs a dual defect marking mechanism. When there are small protrusions on the surface of the concrete member, the lateral force generated by the descent of the spraying pipe causes the concrete member to tilt and push the grinding rod to move. The friction between its rough surface and the surface of the concrete member forms obvious marks. These marks complement the marks lifted by the connecting plate. After the staff discovers the problem parts marked by the connecting plate, they can quickly review and confirm according to the friction marks on the surface of the concrete member, effectively reducing the probability of misjudgment. At the same time, it avoids manual detailed inspection of each part, greatly improving the accuracy and efficiency of identifying defective concrete members, and providing a reliable basis for subsequent targeted treatment.

[0026] Preferably, a cleaning port is provided on the partition board, and a cover body is detachably connected to the cleaning port.

[0027] The beneficial effects of this solution are as follows: This design provides a convenient maintenance channel for the maintenance device by setting a cleaning port and a detachable cover body. When concrete residues, sediment and other impurities accumulate in the collection tank, the cover body can be opened to quickly clean the collection tank below the partition board.

[0028] Preferably, it further includes a control unit which includes a controller and an alarm. A pressure detection unit is provided between the mounting plate and the connecting rod. The pressure detection unit includes a pressure sensor and a second elastic member. A third mounting groove is provided at the bottom of the mounting plate. The pressure sensor is mounted at the bottom of the receiving groove. A transition block is mounted on the pressure sensor. The second elastic member is connected between the transition block and the connecting rod. The first driving member, the alarm, and the pressure sensor are all electrically connected to the controller.

[0029] The beneficial effects of this solution are as follows: Through the collaborative design of the control unit and the pressure detection unit, intelligent defect detection is realized. The pressure sensor monitors the pressure change in real time during the descent of the spraying pipe. When there is a large protrusion on the surface of the concrete member that hinders the descent of the spraying pipe, the pressure sensor feeds back the signal to the controller. The controller controls the alarm to give an alarm according to the preset pressure threshold, accurately identifies the unqualified concrete member, and synchronously controls the first driving member to contract, so that the spraying pipe can be withdrawn in time to avoid equipment damage. The second elastic member plays a role in buffering and resetting, ensuring the sensitivity and stability of pressure detection. This design does not require manual intervention, significantly improves the detection efficiency and accuracy, and ensures the intelligence and reliability of the curing operation.

[0041] Embodiment 1

[0042] As Figure 1 shown, a concrete member 14 curing device includes a curing chamber 1 and a plurality of vibration marking units.

[0043] As Figure 1 and Figure 5 shown, a switch door 2 is hinged to the front side of the curing chamber 1. A partition 3 is installed in the curing chamber 1 by bolts. The partition 3 divides the curing chamber 1 into upper and lower parts. The part above the partition 3 is the curing area 4, and the part below the partition 3 is the collection area 5. A collection groove is formed in the curing chamber 1 below the partition 3. A drain pipe 6 is installed on the right side of the curing chamber 1, and the drain pipe 6 is communicated with the collection groove. A cleaning port is formed in the partition 3, and a cover body 7 is clamped on the cleaning port. By providing a cleaning port on the partition 3, it is convenient to regularly clean the collection groove.

[0044] As Figure 1 and Figure 2As shown in the figure, the curing area 4 is provided with a positioning unit. The positioning unit includes a second driving member 8 and a positioning plate 9. The second driving member 8 is installed on the right outer wall of the curing chamber 1 through bolts. The output shaft of the second driving member 8 passes through the right side wall of the curing chamber 1 and is located inside the curing chamber 1. The positioning plate 9 is installed on the output shaft of the second driving member 8 through bolts. Two connecting bars 10 are welded to the top of the positioning plate 9. Sliders 11 are integrally formed at the tops of the connecting bars 10. Two transverse sliding rails are installed on the inner side surface of the top of the curing chamber 1 through bolts. The sliding rails correspond to the sliders 11 one by one, and the sliders 11 are slidably arranged in the sliding rails and can slide left and right along the sliding rails. The second driving member 8 can accurately control the sliding distance of the positioning plate 9. Four first limiting grooves 12 are formed on the left side surface of the positioning plate 9. Four second limiting grooves 13 are formed on the left inner side surface of the curing chamber 1. The second limiting grooves 13 correspond to the first limiting grooves 12 one by one. The widths of the second limiting grooves 13 and the first limiting grooves 12 are both larger than the thickness of the concrete member 14.

[0045] As Figure 1 and Figure 2 shown in the figure, a lifting spraying unit is arranged on the top of the curing area 4. The lifting spraying unit includes a mounting plate 15. A first driving member 16 is installed on the top of the curing chamber 1 through bolts. The output shaft of the first driving member 16 passes through the top of the curing chamber 1 and is connected to the top of the mounting plate 15 through bolts. The first driving member 16 can drive the spraying unit to lift. Five groups of spraying parts are arranged at the bottom of the mounting plate 15. The adjacent spraying parts are arranged at intervals and can contact the side surface of the concrete member 14. The spraying parts are used for spraying water on the concrete member 14. In this embodiment, both the first driving member 16 and the second driving member 8 are selected as cylinders of model SC40.

[0046] As Figures 1-3 shown in the figure, each group of spraying parts includes a spraying pipe 17 and a connecting rod 18. The spraying pipe 17 can contact the side surface of the concrete member 14. The upper end of the connecting rod 18 is welded to the bottom of the mounting plate 15. The lower end of the connecting rod 18 is welded to the top of the spraying pipe 17. A number of downwardly inclined first nozzles 19 are arranged axially on the side of the spraying pipe 17 close to the concrete member 14. The first nozzles 19 are arranged close to the bottom of the spraying pipe 17. The first nozzles 19 can spray water onto the side surface of the concrete member 14. A number of second nozzles 20 are installed at both the left and right ends of the spraying pipe 17. The second nozzles 20 can spray water onto the concrete member 14 in the second limiting grooves 13 and the first limiting grooves 12. Two pressing rods 21 are welded to the bottom of the spraying pipe 17. The two pressing pipes respectively correspond to the vibration marking units on both sides of the concrete member 14.

[0047] As Figure 2As shown, a water supply section is provided on the right side of the mounting plate 15. The water supply section includes a water supply pipe 22, which is welded to the right side surface of the mounting plate 15. Five water delivery pipes 23 are connected to the bottom of the water supply pipe 22. The water delivery pipes 23 correspond to the spray pipes 17 one by one, and the lower ends of the water delivery pipes 23 are connected to the spray pipes 17. A water supply hose is connected to the front side of the water supply pipe 22, and the water supply hose is connected to a water source.

[0048] As Figure 4 shown, two vibration marking units are correspondingly arranged for each concrete member 14. The concrete member 14 is located between the two vibration marking units and can be in contact with them. The concrete member 14 is positioned by the vibration marking units, so that there is a gap between the side surfaces at both ends of the concrete member 14 and the side surfaces of the first limiting groove 12 and the second limiting groove 13. Thus, an unobstructed spraying space is created for the second nozzle 20, ensuring that the curing water can smoothly and evenly cover both ends of the concrete member 14, greatly improving the curing effect and efficiency of the concrete member 14 inserted into the first limiting groove 12 and the second limiting groove 13.

[0049] As Figures 5-6 shown, each vibration marking unit includes a connecting plate 24 and a moving part. A receiving groove 25 is formed on the upper side surface of the partition plate 3. First elastic members 26 are welded to both the left and right sides of the bottom of the receiving groove 25. The connecting plate 24 is welded above the first elastic members 26. Six water permeable holes 28 are formed in the connecting plate 24. A strip-shaped hole 27 is formed in the bottom of the receiving groove 25. The water permeable holes 28 are communicated with the collecting groove through the strip-shaped hole 27. It should be noted that in this embodiment, for the convenience of illustration, the number of the water permeable holes 28 is six, but it is not limited thereto. In this embodiment, the first elastic members 26 are compression springs.

[0050] As Figure 4 and Figures 7-8As shown in the figure, the structure of each vibration identification unit is the same. Taking the moving part on the leftmost side of the partition plate 3 as an example for description. The moving part includes a grinding rod 29, and the grinding rod 29 is L-shaped. The side of the grinding rod 29 close to the concrete member 14 is an inclined surface. A first installation groove 30 is opened on the partition plate 3. The left side of the first installation groove 30 is an open end. A guiding hole 31 is opened on the partition plate 3 above the first installation groove 30. The guiding hole 31 communicates with the first installation groove 30. The lower end of the grinding rod 29 is slidably arranged in the first installation groove 30. The upper end of the grinding rod 29 extends out of the guiding hole 31 and is located above the partition plate 3. The guiding hole 31 guides the sliding of the grinding rod 29. A second installation groove 32 is opened on the connecting plate 24. The right end of the second installation groove 32 is an open end. The first installation groove 30 is opposite to the second installation groove 32. A through hole 33 penetrating the second installation groove 32 is opened on the connecting plate 24. The pressing rod 21 can pass through the through hole 33. A first wedge-shaped block 34 is welded to the left end of the grinding rod 29. A baffle 35 is integrally formed on the left side of the first wedge-shaped block 34. A waist-shaped hole 36 is opened on the baffle 35 and the first wedge-shaped block 34. The pressing rod 21 can pass through the waist-shaped hole 36. The baffle 35 on the left side of the waist-shaped hole 36 is a shielding part 37. The shielding part 37 can shield the through hole 33. When the grinding rod 29 contacts the concrete member 14, the shielding part 37 can shield the through hole 33. A second wedge-shaped block 38 is welded to the top of the second installation groove 32. The second wedge-shaped block 38 is adapted to the first wedge-shaped block 34, and the first wedge-shaped block 34 can jack up the second wedge-shaped block 38.

[0051] The specific implementation process is as follows:

[0052] During the curing operation of the concrete member 14, first insert the left end of the concrete member 14 into the second limiting groove 13 on the left inner wall of the curing chamber 1; then start the second driving member 8 installed on the right outer wall of the curing chamber 1, and its output shaft extends and drives the positioning plate 9 to move along the transverse slide rail towards the second limiting groove 13, so that the right end of the concrete member 14 is inserted into the first limiting groove 12 on the left side of the positioning plate 9. During this process, the side of the concrete member 14 contacts the grinding rod 29 of the vibration identification unit, and the shielding part 37 on the first wedge-shaped block 34 immediately covers the through hole 33 of the partition plate 3, ensuring that there is a gap between the two side surfaces of the two ends of the concrete member 14 and the side wall of the limiting groove, leaving an unobstructed spraying space for the second nozzle 20 of the spraying pipe 17, so that the curing water can evenly cover both ends of the concrete member 14. At the same time, the positioning plate 9 only limits the concrete member 14 instead of tightly pressing it, ensuring that the concrete member 14 can tilt flexibly when subjected to external forces, creating conditions for surface protrusion detection.

[0053] After positioning, start the first driving member 16 to drive the spraying pipe 17 to move vertically up and down. During the descending process, the first nozzle 19 arranged axially and obliquely on the side of the spraying pipe 17 continuously sprays water on the side of the concrete member 14 to achieve comprehensive curing of the top and side; the second nozzle 20 at the end sprays water on the left and right ends of the concrete member 14 to ensure that all parts of the component are fully cured.

[0054] In the automatic detection and dredging process, when there are small protrusions on the surface of the concrete member 14, the descending spraying pipe 17 contacts the protrusions to generate a lateral thrust, causing the concrete member 14 to tilt and pushing the grinding rod 29 to move in the direction of the second wedge block 38. The first wedge block 34 on the grinding rod 29 cooperates with the inclined surface of the second wedge block 38 to lift the connecting plate 24 to identify the defective member; at the same time, the first wedge block 34 is linked with the grinding rod 29 to drive the shielding portion 37 to move so that the waist hole 36 is aligned with the through hole 33, ensuring that the pressing rod 21 can pass through the baffle 35 smoothly. For the concrete member 14 with a flat surface, when the spraying pipe 17 descends, the pressing rod 21 directly presses down the shielding portion 37, and the elastic member is compressed and reset to drive the connecting plate 24 to vibrate, shaking off the concrete residue at the water permeable hole 28, realizing the automatic dredging of the curing surplus water channel. This process can complete the defect detection and the cleaning of the water permeable hole 28 in real time during the curing operation without manual intervention, which not only ensures the continuous and efficient curing work, but also significantly improves the identification efficiency of defective members and the overall operation reliability of the curing device.

[0055] Embodiment 2

[0056] On the basis of Embodiment 1, it further includes a control unit, and the control unit includes a controller and an alarm. As Figure 9 shown, a pressure detection unit is provided between the mounting plate 15 and the connecting rod 18. The pressure detection unit includes a pressure sensor 40 and a second elastic member 42. A third mounting groove 39 is opened at the bottom of the mounting plate 15. The pressure sensor 40 is installed at the bottom of the third mounting groove 39. A transition block 41 is installed on the pressure sensor 40. The second elastic member 42 is connected between the transition block 41 and the connecting rod 18. The first driving member 16, the alarm, and the pressure sensor 40 are all electrically connected to the controller. When curing the concrete member 14, the first driving member 16 is started, and the output shaft of the first driving member 16 extends to drive the spraying portion to descend and spray the curing water on the concrete member 14. During the descent of the spraying pipe 17, when there are large concrete protrusions on the concrete member 14, the spraying pipe 17 cannot continue to descend. At this time, the pressure information fed back by the pressure sensor 40 exceeds the preset value of the controller, and the controller controls the alarm to give an alarm to remind the operator that the concrete member 14 is a defective product. At the same time, the controller controls the output shaft of the first driving member 16 to contract, driving the spraying pipe 17 to move to the side away from the concrete member 14. In this embodiment, the second elastic member 42 is a compression spring, the controller selects a single-chip microcomputer of model STC89C51, and the model of the pressure sensor 40 is LPS22HB.
