Description

Technical Field

[0001] This invention belongs to the field of concrete curing technology, specifically referring to a curing spray device for precast concrete components. Background Technology

[0002] If the weather is hot and the air is dry after the concrete is poured, and curing is not carried out in time, 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. As a result, flaking or powdering will occur on the concrete surface, leading to the scrapping of the precast concrete component. Therefore, curing in the initial stage after concrete pouring is very important, and curing should be carried out immediately after the concrete has set.

[0003] Existing curing spray systems for precast concrete components mainly use water pumps to extract water from tanks and spray water mist onto the precast components through spray pipes for curing. However, the spray range of most curing spray systems is difficult to adjust according to the width and height of the precast concrete components, affecting the curing effect. In addition, existing curing spray systems cannot perform multi-directional spray curing on irregularly shaped precast concrete components, which can easily cause localized drying of the precast components. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a precast concrete component curing spraying device capable of adjusting the spraying range according to the overall size of the precast concrete component and simultaneously providing circumferential curing spraying for irregularly shaped precast components. Utilizing a telescopic structure, the extended support frame adapts to different sizes of precast concrete components. Employing a pre-action principle combined with electromagnetic principles, the top spraying mechanism drives the suspended side spraying mechanism to rotate, converting the lifting spraying assembly into a circumferential spraying mode, adapting to irregularly shaped precast components and preventing localized drying. Furthermore, using electromagnetic principles, cleaning blocks intermittently clean dust adhering to the top spray head, preventing clogging.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: The present invention provides a precast concrete component curing spraying device, including an extended support frame mechanism, a top spraying mechanism movably provided at the lower part of the extended support frame mechanism, a cleaning mechanism provided inside the top spraying mechanism, suspended side spraying mechanisms symmetrically provided on both sides of the top spraying mechanism, and a lifting spraying component movably provided on the suspended side spraying mechanism.

[0006] Furthermore, the top spraying mechanism includes a connecting column, a top water tank, top spray heads, and a fixing frame. The connecting column is rotatably connected to the lower center of the extended support frame mechanism. The top water tank is connected to the lower end of the connecting column and is hollow. The lower wall of the top water tank is arc-shaped. The top spray heads are evenly distributed at the lower part of the top water tank, and water is evenly sprayed through the top spray heads to avoid high-pressure water jets impacting the surface of the components and causing mortar loss. The fixing frames are symmetrically arranged in pairs at the ends of the top water tank.

[0007] Furthermore, the suspended side spray mechanism includes a supporting side plate, a connecting rod, a power wheel, and a follower wheel. The supporting side plate is vertically and movably mounted at both ends of the top water tank. The connecting rod is symmetrically mounted on both sides of the upper end of the supporting side plate and is slidably inserted into the fixed frame. The power wheel and the follower wheel are respectively rotatably mounted on the side wall of the supporting side plate near the top water tank. The power wheel is driven by a side spray motor. The follower wheel is located directly below the power wheel. A transfer belt is wound between the power wheel and the follower wheel. The lifting spray assembly is slidably mounted between the power wheel and the follower wheel.

[0008] Preferably, the opposite sidewalls of the supporting side plate are provided with movable grooves, and the middle of the movable grooves is provided with through grooves that penetrate the supporting side plate. The covering surface of the through grooves is located inside the transfer belt, and the inner sidewalls of the through grooves are evenly distributed with actuating rods. The top of the supporting side plate is provided with a positioning telescopic block, which is driven by a telescopic motor. The telescopic end of the positioning telescopic block faces upward, and the outer sidewall of the connecting rod is provided with a rubber pad.

[0009] Furthermore, the lifting spray assembly includes a side spray frame, a second electromagnetic block, a fixed clamping block, a second magnetic plate, and a flipping block. The side spray frame is slidably disposed in a movable groove, and a clearance groove is symmetrically provided through the side spray frame. The conveyor belt passes through the side spray frame and moves within the clearance groove. The second electromagnetic block is symmetrically disposed at both ends of the side spray frame. The fixed clamping block is symmetrically disposed on the side spray frame and is located on the inner side of the conveyor belt. The second magnetic plate is slidably disposed on the side spray frame and moves between the second electromagnetic block and the conveyor belt. The sidewalls of the fixed clamping block and the second magnetic plate facing the conveyor belt are uneven, increasing the friction between the second magnetic plate and the fixed clamping block and the conveyor belt, so that the second magnetic plate and the fixed clamping block can firmly squeeze and clamp the conveyor belt. The flipping block is rotatably disposed between the symmetrical fixed clamping blocks. Spray nozzles are provided on the opposite sidewalls of the symmetrical flipping blocks. The spray nozzles are spray-type nozzles. A toggle block is symmetrically disposed on the side of the flipping block away from the spray nozzle, and the toggle block is movably disposed between the toggle rods.

[0010] The power rotor rotates and drives the follower rotor to rotate via the transfer belt. Two symmetrical second electromagnetic blocks generate magnetism when energized, but the currents within the two blocks are opposite, meaning their magnetic poles are opposite. One second electromagnetic block's magnetic pole is opposite to the second magnetic plate's magnetic pole, attracting the second magnetic plate, while the other second electromagnetic block's magnetic pole is the same as the second magnetic plate's magnetic pole, repelling it. The power rotor rotates clockwise. When the side spray frame slides to the lower end of the movable slot, the magnetic pole of the second electromagnetic block on the left is the same as the second magnetic plate's magnetic pole. Under the action of magnetic repulsion, the second magnetic plate approaches the fixed clamping block, and the left-side second magnetic plate presses against the fixed clamping block, holding the transfer belt in place. Meanwhile, the magnetic pole of the second electromagnetic block on the right is opposite to the second magnetic plate's magnetic pole, attracting... The second magnetic plate is attached. The second magnetic plate on the right side is away from the fixed clamping block. Driven by the left-side conveyor belt, the lifting spray assembly moves upward. When the side spray frame slides to the upper end of the movable groove, the current flowing through the second electromagnetic block reverses, causing the magnetic pole of the second electromagnetic block on the right side to be the same as the magnetic pole of the second magnetic plate. Under the action of magnetic repulsion, the second magnetic plate moves closer to the fixed clamping block. The second magnetic plate on the right side and the fixed clamping block squeeze and hold the conveyor belt, while the magnetic pole of the second electromagnetic block on the left side is opposite to the magnetic pole of the second magnetic plate, attracting the second magnetic plate. The second magnetic plate on the left side moves away from the fixed clamping block and no longer holds the conveyor belt. As a result, the lifting spray assembly moves downward under the drive of the right-side conveyor belt. This cycle is repeated to achieve the technical effect of the lifting spray assembly moving up and down.

[0011] Furthermore, the extended support frame mechanism includes a main support frame, a water pump, a support plate, an electric telescopic column, and support rods. The water pump is located at the upper center of the main support frame, and its outlet is connected to an infusion pipe. The support plate is located at the lower part of the main support frame and is cylindrical. The infusion pipe passes through the center of the support plate, and the lower wall of the support plate is provided with a circular slide rail. The electric telescopic column is symmetrically located at both ends of the main support frame and is driven by an adjusting motor. The telescopic end of the electric telescopic column is provided with an adjusting groove, and the output end of the positioning telescopic block is movably inserted into the adjusting groove. The support rods are vertically symmetrically located on both sides of the main support frame. The upper end of the support rod is fitted with a telescopic vertical rod that slides within it. The telescopic vertical rod is fixed to the support rod by a pin, and the upper end of the telescopic vertical rod is connected to the telescopic end of the electric telescopic column. The lower end of the support rod is evenly distributed with casters.

[0012] Furthermore, the top spraying mechanism also includes a main power motor, a power gear, and a support slide column. The main power motor is located at the lower part of the support plate, and the power gear is located at the output end of the main power motor. The connecting column is rotatably connected to the lower center of the support plate. A follower gear is sleeved on the outer wall of the connecting column, and the power gear meshes with the follower gear. A main pipe is provided through the center of the connecting column, and the main pipe is connected to the inner side of the top water tank. A branch pipe is provided on the side wall of the connecting column, and the branch pipe is located above the follower gear. The branch pipe is T-shaped, and the main pipe and the branch pipe are connected to the infusion pipe. The two ends of the branch pipe are respectively connected to symmetrical spray nozzles with liquid passage pipes, and the liquid passage pipes pass through the flip block. The support slide columns are symmetrically arranged at the upper ends of the top water tank, and the upper end of the support slide column is slidably arranged in the surrounding slide rail.

[0013] Preferably, a fixed motor is provided on the outer side of the fixed frame, and a fixed block is provided at the output end of the fixed motor. The fixed block is a telescopic block, and the telescopic direction of the fixed block is towards the rubber pad.

[0014] Furthermore, the cleaning mechanism includes a first electromagnetic block, a frame plate, a first magnetic plate, and cleaning connecting rods. The first electromagnetic block is symmetrically embedded in the inner upper wall of the top water tank. The frame plate is horizontally positioned inside the top water tank and has a fence structure. The first magnetic plate is symmetrically positioned above the frame plate and below the first electromagnetic block. The cleaning connecting rods are evenly distributed and connected to the lower part of the frame plate. The distribution trajectory of the cleaning connecting rods matches the arc-shaped lower wall of the top water tank. Cleaning inserts are evenly distributed on the lower part of the cleaning connecting rods. The cleaning inserts are arranged in an inverted cone shape and are movably inserted into the top spray head. The upper part of the frame plate is symmetrically provided with sliding columns. The sliding columns slide through and slide on the upper wall of the top water tank. A return spring connects the upper wall of the top water tank and the frame plate. Multiple sets of the return springs are symmetrically arranged on the sliding columns. On both sides of the moving column; initially, under the action of gravity and the elastic action of the return spring, the frame plate and cleaning rod are in the lower part of the top water tank. The cleaning insert is inserted into the top spray head to block it, and water is stored in the top water tank. Then, the first electromagnetic block is energized and generates magnetism. The magnetic pole of the first electromagnetic block is opposite to the magnetic pole of the first magnetic plate, thus attracting the first magnetic plate, causing the frame plate and cleaning rod to move upward. The return spring is compressed, and the cleaning insert slides out of the top spray head. The water in the top water tank flows out through the top spray head and is gently sprayed on the top of the precast concrete component for curing. Subsequently, the first electromagnetic block is de-energized and no longer attracts the first magnetic plate. The cleaning insert is reinserted into the top spray head under the action of gravity and the elastic action of the return spring. The cleaning insert, which moves up and down, intermittently cleans the dust adhering to the top spray head to avoid clogging and affecting the spraying effect.

[0015] The beneficial effects achieved by the present invention using the above structure are as follows:

[0016] 1. This invention provides a curing spraying device for precast concrete components, which adopts a telescopic structure. The electric telescopic column and telescopic vertical rod can extend and retract according to the width and height of the precast concrete components. When the height of the telescopic vertical rod is adjusted, the support plate drives the top spraying mechanism to move. When the width of the electric telescopic column is adjusted, the suspended side spraying mechanism moves and adjusts accordingly under the restriction of the adjustment groove. This achieves the technical effect that the overall size of the device can be adjusted according to the size of the precast concrete components.

[0017] 2. Utilizing the principle of pre-action combined with electromagnetic principles, when the positioning telescopic block retracts, the suspended side spraying mechanism is no longer restricted by the adjustment groove. At the same time, the top spraying mechanism and the suspended side spraying mechanisms on both sides are positioned and connected into a whole through the fixing block. Then, the top spraying mechanism drives the suspended side spraying mechanism to rotate on the outside of the precast component, changing the lifting spraying component from the lifting layered spraying mode to the surrounding spraying mode. This adapts to irregularly shaped precast components and provides multi-directional spraying curing for the precast concrete components, avoiding localized drying.

[0018] 3. The cleaning mechanism, based on electromagnetic principles, initially inserts the cleaning block into the top spray head. Subsequently, the first electromagnetic block is energized and generates magnetism. Since the magnetic poles of the first electromagnetic block are opposite to those of the first magnetic plate, the cleaning block attracts the first magnetic plate, causing it to slide out of the top spray head. When the first electromagnetic block is de-energized, the cleaning block re-inserts into the top spray head. The intermittent up-and-down shaking cleaning block cleans the dust adhering to the top spray head, preventing clogging and ensuring effective spraying. Attached Figure Description

A main pipe runs through the center of the connecting column 17 and communicates with the inside of the top water tank 15. Branch pipes 22 are provided on the side wall of the connecting column 17. The branch pipes 22 are T-shaped. The main pipe and the branch pipes 22 are connected to the infusion pipe. The lower wall of the top water tank 15 is arc-shaped. Top spray heads 16 are evenly distributed on the lower part of the top water tank 15. The ends of the top water tank 15 are symmetrically arranged in pairs on both sides. A fixed frame 23 is provided with a fixed motor 36 on its outer side. The output end of the fixed motor 36 is provided with a fixed block 24, which is a telescopic block.

The upper end of the supporting sliding column 21 is slidably provided in the surrounding slide rail 13.

[0037] The cleaning mechanism 4 includes a first electromagnetic block 25 and a frame plate 26. The first electromagnetic block 25 is symmetrically embedded in the inner upper wall of the top water tank 15. The frame plate 26 is horizontally positioned inside the top water tank 15 and adopts a grid structure. The frame plate 26 slides up and down within the top water tank 15. A first magnetic plate 27 is symmetrically arranged on the upper part of the frame plate 26, located below the first electromagnetic block 25. Cleaning connecting rods 29 are evenly distributed and connected below the frame plate 26. The distribution trajectory matches the arc-shaped lower wall of the top water tank 15. Cleaning blocks 30 are evenly distributed on the lower part of the cleaning linkage 29. The cleaning blocks 30 are arranged in an inverted cone shape and are movably inserted into the top spray head 16. Sliding columns 28 are symmetrically arranged on the upper part of the frame plate 26. The sliding columns 28 slide through the upper wall of the top water tank 15. A return spring 31 is connected between the upper wall of the top water tank 15 and the frame plate 26. Multiple sets of return springs 31 are symmetrically arranged on both sides of the sliding column 28.

[0038] The suspended side spray mechanism 3 includes a supporting side plate 32, which is vertically and movably mounted at both ends of the top water tank 15. Connecting rods 33 are symmetrically arranged on both sides of the upper end of the supporting side plate 32. The connecting rods 33 are slidably inserted into the fixed frame 23. A rubber pad 34 is provided on the outer wall of the connecting rod 33, and the extension / retraction direction of the fixed block 24 faces the rubber pad 34. A power wheel 37 and a follower wheel 38 are rotatably mounted on the side wall of the supporting side plate 32 near the top water tank 15. The power wheel 37 is driven by a side spray motor, and the follower wheel 38 is located directly below the power wheel 37. A conveyor belt 39 is wound between the power wheel 37 and the follower wheel 38. The lifting spray assembly 5 is slidably mounted between the power wheel 37 and the follower wheel 38.

[0039] The support side plate 32 has a movable groove 40 on its opposite side wall. The middle of the movable groove 40 passes through the support side plate 32 and has a through groove 41. The covering surface of the through groove 41 is inside the transfer belt 39. The inner side wall of the through groove 41 is evenly distributed with actuating rods 42. The top of the support side plate 32 has a positioning telescopic block 35. The positioning telescopic block 35 is driven by a telescopic motor. The telescopic end of the positioning telescopic block 35 faces upward. The output end of the positioning telescopic block 35 is movably inserted into the adjustment groove 11.

[0040] The lifting spray assembly 5 includes a side spray frame 43, which is slidably disposed within a movable groove 40. Symmetrical clearance grooves are provided through the side spray frame 43. A conveyor belt 39 passes through the side spray frame 43 and moves within the clearance grooves. Second electromagnetic blocks 44 are symmetrically disposed at both ends of the side spray frame 43. Fixed clamping blocks 45 are symmetrically disposed on the side spray frame 43, located inside the conveyor belt 39. A second magnetic plate 46 is slidably disposed on the side spray frame 43, moving between the second electromagnetic blocks 44 and the conveyor belt 39. The sidewalls of the fixed clamping blocks 45 and the second magnetic plate 46 facing the conveyor belt 39 are uneven, increasing the friction between the second magnetic plate 46, the fixed clamping blocks 45, and the conveyor belt 39. This allows the second magnetic plate 46 and the fixed clamping blocks 45 to firmly press and clamp the conveyor belt 39. The symmetrical fixed clamping blocks 45 rotate between each other. A flipping block 47 is provided, and nozzles 49 are provided on the opposite side walls of the symmetrical flipping block 47. The nozzles 49 are spray nozzles. A toggle block 48 is symmetrically provided on the side of the flipping block 47 away from the nozzles 49. The toggle block 48 is movably disposed between the toggle rods 42. The symmetrical nozzles 49 are respectively connected to the two ends of the branch pipe 22 by liquid pipes 50, which pass through the flipping block 47. The power wheel 37 rotates and drives the follower wheel 38 to rotate through the transfer belt 39. The two symmetrical second electromagnetic blocks 44 generate magnetism when energized, but the currents in the two second electromagnetic blocks 44 are opposite, that is, the magnetic poles of the two second electromagnetic blocks 44 are different. The magnetic pole of one second electromagnetic block 44 is different from the magnetic pole of the second magnetic plate 46 and attracts the second magnetic plate 46. The magnetic pole of the other second electromagnetic block 44 is the same as the magnetic pole of the second magnetic plate 46 and repels the second magnetic plate 46.

[0041] The power wheel 37 rotates clockwise. When the side spray frame 43 slides to the lower end of the movable groove 40, the magnetic pole of the second electromagnetic block 44 on the left side is the same as the magnetic pole of the second magnetic plate 46. Under the action of magnetic repulsion, the second magnetic plate 46 approaches the fixed clamping block 45, and the second magnetic plate 46 on the left side squeezes and clamps the transfer belt 39 with the fixed clamping block 45. Meanwhile, the magnetic pole of the second electromagnetic block 44 on the right side is opposite to the magnetic pole of the second magnetic plate 46, attracting the second magnetic plate 46. The second magnetic plate 46 on the right side moves away from the fixed clamping block 45. 5. Driven by the left-side conveyor belt 39, the lifting spray assembly 5 moves upward. When the side spray frame 43 slides to the upper end of the movable slot 40, the current flowing through the second electromagnetic block 44 reverses, causing the magnetic pole of the second electromagnetic block 44 on the right side to be the same as the magnetic pole of the second magnetic plate 46. Under the action of magnetic repulsion, the second magnetic plate 46 approaches the fixed clamping block 45. The second magnetic plate 46 on the right side and the fixed clamping block 45 squeeze and clamp the conveyor belt 39, while the magnetic pole of the second electromagnetic block 44 on the left side and the second magnetic plate 46 move upward. The magnetic poles of plate 46 are opposite, attracting the second magnetic plate 46. The second magnetic plate 46 on the left moves away from the fixed clamping block 45 and no longer clamps the transfer belt 39, thus causing the lifting spray assembly 5 to move downward under the drive of the right transfer belt 39. This cycle is repeated, achieving the technical effect of the lifting spray assembly 5 moving up and down in a cyclical manner. During the upward sliding of the side spray frame 43, under the influence of the liquid pipe 50, the initial orientation of the nozzle 49 is diagonally downward, and as the side spray frame 43 moves upward, the orientation of the nozzle 49 gradually changes from diagonal to downward. The direction changes from downward to upward, during which the actuating block 48 is intermittently blocked and actuated by the actuating rod 42; similarly, as the side spray frame 43 slides downward, the initial orientation of the nozzle 49 is upward, and as the side spray frame 43 moves downward, the orientation of the nozzle 49 gradually changes from upward to downward. During this period, the actuating block 48 is intermittently blocked and actuated by the actuating rod 42, thereby causing the nozzle 49 on the flipping block 47 to swing up and down between the symmetrical fixed clamping blocks 45; achieving the technical effect of large-area spraying.

[0042] Working principle and workflow:

[0043] In practical use, first connect the water pump 14 to the external water tank, and adjust the height and width of the extended support frame mechanism 1 according to the overall size of the precast concrete component; specifically, support the top support plate 12, adjust the extension and retraction between the support rod 8 and the telescopic vertical rod 9, and then adjust the height of the top spraying mechanism 2 so that its height is higher than the precast component. After adjustment, position the support rod 8 and the telescopic vertical rod 9 with pins. Then, directly start the adjustment motor to adjust the extension and retraction of the electric telescopic column 7, thereby pushing the support rods 8 on both sides of the main support frame 6 to expand or retract. At this time, the fixed motor 36 causes the fixed block 24 to retract, and the connecting plug... The rod 33 can slide within the fixed frame 23. The telescopic motor extends the positioning telescopic block 35, which is then inserted into the adjustment slot 11. As the electric telescopic column 7 is extended and adjusted, the suspended side spray mechanism 3 is adjusted as a whole. After the extended support frame mechanism 1 is fully adjusted, the fixed motor 36 is started, causing the fixed block 24 to extend and press the rubber pad 34. This positions the connecting rod 33 relative to the fixed frame 23, making the top spraying mechanism 2 and the suspended side spray mechanisms 3 on both sides form a whole. This achieves the technical effect that the overall size of the device can be adjusted according to the size of the precast concrete components.

[0044] Then, the casters 10 are controlled to move the entire device outside the arranged precast concrete components. During this time, the water pump 14 pumps water and sends it into the top water tank 15 and the liquid pipe 50 through the main pipe and branch pipe 22 of the connecting column 17, respectively. In the initial state, under the action of gravity and the elastic action of the return spring 31, the frame plate 26 and the cleaning connecting rod 29 are in the lower part of the top water tank 15, and the cleaning insert 30 is inserted into the top spray head 16 to block it, and water is stored in the top water tank 15. Then, the first electromagnetic block 25 is energized to generate magnetism, and the magnetic poles of the first electromagnetic block 25 and the magnetic poles of the first magnetic plate 27 are... The first electromagnetic block 25 is de-energized and no longer attracts the first magnetic plate 27, causing the frame plate 26 and cleaning rod 29 to move upwards. The return spring 31 is compressed, and the cleaning insert 30 slides out of the top spray head 16. Water in the top water tank 15 flows out through the top spray head 16 and is gently sprayed on the top of the precast concrete component for curing. Subsequently, the first electromagnetic block 25 is de-energized and no longer attracts the first magnetic plate 27. The cleaning insert 30 is reinserted into the top spray head 16 under the action of gravity and the elasticity of the return spring 31. The cleaning insert 30, which vibrates up and down, intermittently cleans the dust adhering to the top spray head 16 to avoid clogging and affecting the spraying effect.

[0045] Meanwhile, the water in the liquid pipe 50 is sprayed out through the nozzle 49 to cure the side wall of the precast concrete component; the side spray motor drives the power wheel 37 to rotate clockwise, and the rotation of the power wheel 37 drives the follower wheel 38 to rotate through the transfer belt 39. The two symmetrical second electromagnetic blocks 44 are energized and generate magnetism, but the current in the two second electromagnetic blocks 44 is opposite, that is, the magnetic poles of the two second electromagnetic blocks 44 are different. The magnetic pole of one second electromagnetic block 44 is different from the magnetic pole of the second magnetic plate 46 and attracts the second magnetic plate 46, while the magnetic pole of the other second electromagnetic block 44 is the same as the magnetic pole of the second magnetic plate 46 and repels the second magnetic plate 46.

[0046] When the side spray frame 43 slides to the lower end of the movable groove 40, the magnetic pole of the second electromagnetic block 44 on the left side is the same as the magnetic pole of the second magnetic plate 46. Under the action of magnetic repulsion, the second magnetic plate 46 approaches the fixed clamping block 45. The second magnetic plate 46 on the left side and the fixed clamping block 45 squeeze and clamp the transfer belt 39. Meanwhile, the magnetic pole of the second electromagnetic block 44 on the right side is different from the magnetic pole of the second magnetic plate 46, attracting the second magnetic plate 46. The second magnetic plate 46 on the right side moves away from the fixed clamping block 45. Driven by the transfer belt 39 on the left side, the lifting spray assembly 5 moves upward.

[0047] When the side spray frame 43 slides to the upper end of the movable groove 40, the current flowing through the second electromagnetic block 44 immediately reverses, causing the magnetic pole of the second electromagnetic block 44 on the right side to be the same as the magnetic pole of the second magnetic plate 46. Under the action of magnetic repulsion, the second magnetic plate 46 moves closer to the fixed clamping block 45, and the second magnetic plate 46 on the right side and the fixed clamping block 45 squeeze and clamp the transfer belt 39. Meanwhile, the magnetic pole of the second electromagnetic block 44 on the left side is opposite to the magnetic pole of the second magnetic plate 46, attracting the second magnetic plate 46, and the second magnetic plate 46 on the left side moves away from the fixed clamping block 45. The conveyor belt 39 is no longer clamped, and the lifting spraying assembly 5 moves down under the drive of the right conveyor belt 39. This cycle is repeated, and the lifting spraying assembly 5 moves up and down on both sides of the precast concrete component to spray water. Simultaneously, during the up and down sliding of the side spray frame 43, the actuating block 48 is intermittently blocked and actuated by the actuating rod 42, which causes the nozzle 49 on the flipping block 47 to swing up and down between the symmetrical fixed clamping blocks 45, so that the nozzle 49 can spray a wide area and provide more comprehensive curing for the precast component.

[0048] When precast concrete components have irregular shapes such as internal and external corners or holes, simply start the telescopic motor to retract the positioning telescopic block 35 and slide it out of the adjustment groove 11. The electric telescopic column 7 no longer restricts the suspended side spray mechanism 3. At this time, the main power motor 19 starts and drives the follower gear 18 to rotate through the power gear 20. The top water tank 15 rotates, which in turn causes the top spray mechanism 2 to rotate together with the suspended side spray mechanism 3 and the lifting spray assembly 5. The support slide column 21 slides in the surrounding slide rail 13. During the rotation, it does not affect the operation of the lifting spray assembly 5, thus converting the lifting spray assembly 5 into a surrounding spray curing mode to carry out multi-directional spray curing of irregular precast concrete components and avoid local drying.

[0049] It is worth noting that the caster wheel 10 is a brakeable caster wheel, which is existing technology and will not be elaborated on here.

[0050] The above is the overall workflow of this invention. Simply repeat this process the next time you use it.
