Description

Technical Field

[0001] The invention relates to the field of prefabricated concrete component maintenance, and in particular to a spraying maintenance device and a maintenance method for prefabricated components. Background Art

[0002] Prefabricated components refer to building components that are produced and processed in factories or prefabrication plants and then installed on site. Prefabricated components usually complete most of the processing and handling during the production process and can be assembled and installed directly on the construction site, thereby speeding up the construction progress and reducing the consumption of manpower and resources in on-site construction. Prefabricated components have a wide range of applications and are suitable for residential buildings, commercial buildings, industrial buildings, infrastructure construction and other fields. They can not only improve construction efficiency and quality, but also reduce construction costs and environmental impacts. Therefore, they have been widely used and promoted in modern construction projects. Spray curing of prefabricated components refers to the process of using spraying to perform water curing after the prefabricated components (such as concrete components) are completed in order to ensure their quality and strength development during the curing period. This method is usually suitable for components that need to be moved or used immediately after production, such as bridge beams, beams and columns, wall panels, etc.

[0003] There are some problems in the maintenance of existing prefabricated components. First, workers are required to hold water pipes for mobile spraying, which is not only time-consuming and labor-intensive, but also has low spraying efficiency. Secondly, prefabricated firmware will be added with enhanced curing fluids such as polymer emulsions, silicate solutions or other anti-evaporation agents during maintenance, and they are usually directly connected to municipal water pipes during maintenance. These curing fluids can only be sprayed on the surface of the prefabricated components later and cannot be fully mixed with the water source, resulting in poor curing effects.

[0014] Working principle: First, the staff moves the device to the surface of the prefabricated component, connects the water diversion pipe to the municipal water pipe, and puts the curing liquid into the curing liquid storage tank. Then, they hold the handrail with both hands, control the device to move on the surface of the prefabricated component, turn on the switch of the municipal water pipe, and the water source enters the interior of the first shell through the water diversion pipe, and enters the drain pipe, and is sprayed on the surface of the prefabricated component through all nozzles. At the same time, the water source will drive the water wheel to rotate before entering the drain pipe, and the second driving gear will be driven by the water wheel. The meshing transmission of the rotating second driving gear and the second driven gear drives the worm to rotate, and the worm will mesh with the worm wheel, thereby driving the shaft and the quarter bevel gears on both sides of the shaft to rotate. Since the meshing teeth of the two quarter bevel gears are staggered, when the shaft rotates, the two quarter bevel gears will intermittently mesh with the transmission bevel gear, thereby driving The movable rotating rod swings back and forth, and the swinging rotating rod drives one end of the U-shaped connecting rod to follow the movement, thereby driving the drainage pipe and the sprinkler head to swing back and forth, thereby improving the spraying range and spraying efficiency. Then the brushless motor and the output pump are started, and the output pump pumps the curing liquid in the curing liquid storage tank into the input pipe, and sends it into the multi-way pipe through the delivery pipe, and then into each mixing chamber through the branch pipe. The brushless motor will drive the first driving gear to rotate, drive the two first driven gears to rotate, thereby driving the transmission wheels on the two inner short shafts to rotate, and cooperate with the transmission of the synchronous belt to drive all the short shafts to rotate together, thereby driving all the cross brush plates to rotate at high speed. The high-speed rotating cross brush plate will break the curing liquid entering the mixing chamber into fine water droplets. These fine water droplets mixed with air will form a high-speed curing liquid gas fluid, and the air flow will be fully mixed with the water source sprayed on the surface of the prefabricated component, thereby improving the curing effect.

[0015] A curing method for a prefabricated component spray curing device comprises the following steps:

[0016] Step 1: First, a layer of polymer emulsion composed of acrylate and acrylate copolymer is sprayed on the surface of the prefabricated component to improve its surface permeability and help moisture to enter the interior of the prefabricated component more effectively;

[0017] Step 2: First, the staff moves the device to the surface of the prefabricated component, connects the water pipe to the municipal water pipe, puts the curing liquid into the curing liquid storage tank, and then holds the handrail with both hands to control the device to move on the surface of the prefabricated component;

At the same time, the water source will drive the water wheel to rotate before entering the drain pipe, and the second driving gear will be driven to rotate by the water wheel. With the transmission effect of the second driven gear, worm, worm wheel, quarter bevel gear and transmission bevel gear, the U-shaped connecting rod can be driven to swing back and forth, driving the drain pipe and the nozzle to swing together, thereby improving the spraying range and spraying efficiency;

[0019] Step 4: Start the brushless motor and the output pump. The output pump inputs the curing liquid into each mixing chamber. The brushless motor drives the first driving gear to rotate, cooperates with the transmission of the first driven gear, the transmission wheel and the synchronous belt, drives all the short shafts and the cross brush plate to rotate at high speed, and breaks the curing liquid into fine water droplets. After mixing with air, it forms a high-speed air-flow, and finally mixes in the clean water on the surface of the prefabricated component to improve the curing effect;

[0020] Step 5: After completion, a layer of mineral oil film is sprayed on the surface of the prefabricated component. The oil film covering the water surface can effectively slow down the evaporation rate of water. Finally, a layer of porous ceramic mesh is covered on the surface to reduce the surface area of ​​the water surface exposed to the air and reduce evaporation.

[0036] In this embodiment, a brushless motor 8 is fixedly installed in the middle of the top of the mixing chamber 2, and the driving end of the brushless motor 8 extends to the interior of the mixing chamber 2 and is fixedly installed with a first driving gear 9. The bottom end of the first driving gear 9 is connected to the surface of the fixed frame 11 through a movable shaft, and the top of the inner short shaft 4 is fixedly installed with a first driven gear 10, and the inner end of the first driven gear 10 is meshed and connected with the outer side of the first driving gear 9. The first driving gear 9 is driven to rotate by the brushless motor 8, driving the first driven gears 10 on both sides to rotate at high speed.

[0037] Furthermore, a transmission wheel 6 is fixedly connected to the upper outer diameter of the short shaft 4, and the outer diameters of the transmission wheels 6 on both sides are connected by a synchronous belt 7.

[0038] Furthermore, an output pump 12 is fixedly installed on one side of the top of the mixing chamber 2, and a delivery pipe 13 is fixedly installed on the output end of the output pump 12. The curing liquid is delivered to the interior of the mixing chamber 3 through the output pump 12 and the delivery pipe 13. The end of the delivery pipe 13 is fixedly connected to the middle of the multi-way pipe 14, and the inner end has a plurality of connecting channels. A plurality of branch pipes 15 are fixedly installed on the inner end of the multi-way pipe 14, and the ends of the branch pipes 15 extend to the interior of the corresponding side mixing chamber 3. The curing liquid is delivered to each mixing chamber 3 through the branch pipes 15. A curing liquid storage tank 16 is fixedly connected to the other side of the top of the mixing chamber 2, and the interior is filled with curing liquid, including polymer emulsion, silicate solution or other anti-evaporation agent. These additives can help retain moisture during curing, provide additional protection, and promote the early strength development of concrete to a certain extent. The input end of the output pump 12 extends to the inner bottom of the curing liquid storage tank 16 through the input pipe 17.

[0039] Specifically, the brushless motor 8 and the output pump 12 are started, and the output pump 12 pumps the curing liquid in the curing liquid storage tank 16 into the input pipe 17, and sends it into the multi-way pipe 14 through the delivery pipe 13, and then sends it into each mixing chamber 3 through the branch pipe 15. The brushless motor 8 will drive the first driving gear 9 to rotate, drive the two first driven gears 10 to rotate, thereby driving the transmission wheel 6 on the two inner short shafts 4 to rotate, cooperate with the transmission of the synchronous belt 7, drive all the short shafts 4 to rotate together, thereby driving all the cross brush plates 5 to rotate at high speed, and the high-speed rotating cross brush plates 5 will break the curing liquid entering the mixing chamber 3 into fine water droplets. These fine water droplets mixed with air will form a high-speed curing liquid gas fluid, and the airflow will be fully mixed with the water source sprayed on the surface of the prefabricated component, thereby improving the curing effect.

[0040] Furthermore, a water wheel 21 is movably installed on one side of the interior of the first shell 18 near the drain pipe 20, and a guide plate can be installed in the first shell 18. Water will flow from the inside of the first shell 18, driving the water wheel 21 to rotate. A second shell 22 is fixedly connected to one side of the middle part of the first shell 18 to provide fixed protection. The middle part of the water wheel 21 extends to the inside of the second shell 22 through a movable shaft and is fixedly connected to a second driving gear 23. A second driven gear 24 is movably installed on the lower side of the interior of the second shell 22 and the second driven gear 24 is meshed and connected with the inner end of the second driving gear 23. The second driven gear 24 is connected to one side of the inner wall of the second shell 22 through a movable shaft and a bearing seat. The rotating water wheel 21 drives the second driving gear 23 to rotate, thereby driving the second driven gear 24 to rotate.

[0041] Furthermore, a worm 25 is connected to the middle part of the second driven gear 24 through a movable shaft, a rotating shaft 26 is movably installed in the middle part of the second housing 22, both ends of the rotating shaft 26 are connected to the inner wall of the second housing 22 through bearing seats, a worm wheel 27 is fixedly connected to the middle outer diameter of the rotating shaft 26, and the worm wheel 27 is meshed with the inner end of the worm 25. The rotating second driven gear 24 will drive the worm 25 to rotate, and the meshing transmission between the worm 25 and the worm wheel 27 will drive the rotating shaft 26 to rotate.

[0042] Furthermore, a quarter bevel gear 28 is fixedly connected to the outer diameter of both sides of the rotating shaft 26, and meshing teeth are provided at only one quarter of the outer side, and the meshing teeth of the two quarter bevel gears 28 are staggered with each other.

The transmission bevel gear 30 is meshed and connected with the inner ends of the two quarter bevel gears 28. When the rotating shaft 26 rotates, the two quarter bevel gears 28 will intermittently mesh and transmit with the transmission bevel gear 30, thereby driving the rotating rod 29 to swing back and forth.

[0043] Furthermore, the outer diameter of the rotating rod 29 is fixedly connected to one end of the U-shaped connecting rod 31 and the other end of the U-shaped connecting rod 31 is fixedly connected to the outer diameter of one side of the drain pipe 20. By swinging the rotating rod 29 back and forth, one end of the U-shaped connecting rod 31 is driven to follow the movement, thereby driving the drain pipe 20 and the nozzle 32 to swing back and forth, thereby improving the spraying range and spraying efficiency.

[0044] Specifically, the municipal water pipe is connected to the water pipe 19, and the switch of the municipal water pipe is turned on. The water source enters the interior of the first housing 18 through the water pipe 19, and enters the drain pipe 20, and is sprayed on the surface of the prefabricated component through all the nozzles 32.

The rotating second driving gear 23 and the second driven gear 24 are meshed and driven to drive the worm 25 to rotate, and the worm 25 will engage with the worm wheel 27. The meshing transmission is carried out, thereby driving the rotating shaft 26 and the quarter bevel gears 28 on both sides of the rotating shaft 26 to rotate. Since the meshing teeth of the two quarter bevel gears 28 are staggered, when the rotating shaft 26 rotates, the two quarter bevel gears 28 will intermittently mesh with the transmission bevel gear 30 for transmission, thereby driving the rotating rod 29 to swing back and forth. By swinging the rotating rod 29 back and forth, one end of the U-shaped connecting rod 31 is driven to follow the movement, thereby driving the drain pipe 20 and the nozzle 32 to swing back and forth, thereby improving the spraying range and spraying efficiency.

[0045] Furthermore, a handrail 33 is fixedly connected to the front side of the top of the bracket 1, and universal wheels 34 are fixedly installed at the four corners of the bottom end of the bracket 1 to facilitate the staff to move the device by hand.

[0047] Step 1: First, a layer of polymer emulsion composed of acrylate and acrylate copolymer is sprayed on the surface of the prefabricated component to improve its surface permeability and help moisture to enter the interior of the prefabricated component more effectively;

[0048] Step 2: First, the staff moves the device to the surface of the prefabricated component, connects the water pipe 19 to the municipal water pipe, puts the curing liquid into the curing liquid storage tank 16, and then holds the handrail 33 with both hands to control the device to move on the surface of the prefabricated component;

At the same time, the water source drives the water wheel 21 to rotate before entering the drain pipe 20, and drives the second driving gear 23 to rotate through the water wheel 21. With the transmission effect of the second driven gear 24, the worm 25, the worm wheel 27, the quarter bevel gear 28 and the transmission bevel gear 30, the U-shaped connecting rod 31 can be driven to swing back and forth, driving the drain pipe 20 and the nozzle 32 to swing together, thereby improving the spraying range and spraying efficiency;

[0050] Step 4: Start the brushless motor 8 and the output pump 12. The output pump 12 inputs the curing liquid into each mixing chamber 3. The brushless motor 8 drives the first driving gear 9 to rotate, cooperates with the transmission of the first driven gear 10, the transmission wheel 6 and the synchronous belt, drives all the short shafts 4 and the cross brush plate 5 to rotate at high speed, and breaks the curing liquid into fine water droplets, which are mixed with air to form a high-speed air-flow, and finally mixed in the clean water on the surface of the prefabricated component to improve the curing effect;

[0051] Step 5: After completion, a layer of mineral oil film is sprayed on the surface of the prefabricated component. The oil film covering the water surface can effectively slow down the evaporation rate of water. Finally, a layer of porous ceramic mesh is covered on the surface to reduce the surface area of ​​the water surface exposed to the air and reduce evaporation.

A curing method based on the spray curing device for prefabricated components according to any one of claims 1 to 9, characterized in that: The following steps are involved: Step 1: First, a layer of polymer emulsion composed of acrylate and acrylate copolymer is sprayed on the surface of the prefabricated component to improve its surface permeability and help moisture to enter the interior of the prefabricated component more effectively; Step 2: The staff then moves the device to the surface of the prefabricated component, connects the water pipe (19) to the municipal water pipe, puts the curing liquid into the curing liquid storage tank (16), and then holds the handrail (33) with both hands to control the device to move on the surface of the prefabricated component; Step 3: Turn on the switch of the municipal water pipe, and the water source enters the interior of the first housing (18) through the water diversion pipe (19), and enters the drainage pipe (20), and is sprayed on the surface of the prefabricated component through all the nozzles (32). At the same time, the water source drives the water wheel (21) to rotate before entering the drainage pipe (20), and drives the second driving gear (23) to rotate through the water wheel (21). In conjunction with the transmission effect of the second driven gear (24), the worm (25), the worm wheel (27), the quarter bevel gear (28) and the transmission bevel gear (30), the U-shaped connecting rod (31) can be driven to swing back and forth, driving the drainage pipe (20) and the nozzle (32) to swing together, thereby improving the spraying range and spraying efficiency; Step 4: Start the brushless motor (8) and the output pump (12), the output pump (12) inputs the curing liquid into each mixing chamber (3), the brushless motor (8) drives the first driving gear (9) to rotate, cooperates with the transmission of the first driven gear (10), the transmission wheel (6) and the synchronous belt, drives all the short shafts (4) and the cross brush plate (5) to rotate at high speed, breaks the curing liquid into fine water droplets, mixes with air to form a high-speed air-flow, and finally mixes in the clean water on the surface of the prefabricated component to improve the curing effect; Step 5: After completion, a layer of mineral oil film is sprayed on the surface of the prefabricated component. The oil film covering the water surface can effectively slow down the evaporation rate of water. Finally, a layer of porous ceramic mesh is covered on the surface to reduce the surface area of ​​the water surface exposed to the air and reduce evaporation.
