Description

Technical Field

[0001] This invention relates to the field of precast beam maintenance, specifically to an automatic spray atomizer for precast beams and its working method. Background Technology

[0002] Precast beams are concrete beam components that are formed, mixed, and poured on-site at a concrete component factory or construction site. After reaching the designed strength, they are transported to the installation location for installation. Precast beams are manufactured in a factory and then transported to the construction site for installation according to the design requirements. Precast beams mainly include precast concrete lintels and precast concrete bridges. Most precast concrete bridges are prestressed components. After pouring, precast beams require on-site curing, which must be done continuously or intermittently during the water curing process. Water is poured onto the concrete surface to keep it moist. The curing time is usually from the shrinkage stage of fresh concrete to the final setting stage. If the frequency and timing of watering are properly controlled, the cost and quality can be kept within a certain range. However, if not controlled properly, the concrete surface will develop micro-cracks due to alternating dryness and wetness, and in severe cases, it will crack. The impact on quality can sometimes be more serious than not curing at all. Moreover, when watering precast beams, appropriate watering equipment needs to be used, which is different from watering large-volume precast beams.

[0003] However, existing water spraying and curing equipment has the following technical problems: During the water spraying and curing process of precast beams, fixed-point nozzles are generally used on both sides of the precast beams, and the fixed-point nozzles continuously spray water on designated parts or areas, which can lead to overspraying and cause the sprayed water to flow down the side wall of the precast beam. Moreover, the excess water cannot be collected and recycled, resulting in water waste. At the same time, it cannot automatically spray atomized water back and forth along the side of the precast beam to a designated height. Therefore, this invention is needed to provide an automatic spraying atomizer for precast beams and its working method to solve the above technical problems. Summary of the Invention

[0012] A method for operating an automatic spray atomizer for precast beams includes the following steps:

[0013] S1. First, fill the water collection tank with water and ensure that the water level is always higher than the vertical pipe. Then start the motor to drive the drive mechanism to move on the side of the upper surface of the precast beam support base. At the same time, the water pump will be driven to run. The water pump will transport the water in the water collection tank to the inside of the extended spray pipe and spray assembly, and spray it out through the first atomizing nozzle and the second atomizing nozzle.

[0014] S2, where the blades will run synchronously with the motor, thereby blowing the water mist sprayed from the second atomizing nozzle to the outer surface of the precast beam, while the first atomizing nozzle will spray the water mist on the top surface of the precast beam, thereby playing a role in curing the precast beam;

[0015] S3. Then control the forward and reverse operation of the motor so that the outer surface of the precast beam can be sprayed with water mist repeatedly for curing by the atomizing spraying mechanism.

[0016] The beneficial effects of this invention are:

[0017] (1) By setting an extended spray section on the top of the drive mechanism, the present invention can atomize and spray the pumped water. At the same time, the spray assembly can blow the atomized water to a specified position and height on the side of the precast beam, thereby preventing the atomized water from overflowing and affecting the quality of precast beam curing.

[0018] (2) By setting a drive mechanism inside the drive mechanism, the present invention can provide power for the operation of the drive mechanism and can extract water from the water collection tank below the automatic walking drive mechanism, thereby enabling the side of the precast beam to be reciprocated and sprayed with atomized spray for curing. Moreover, the water collection tank on the side of the precast beam support base can collect and recycle the excess water from the spraying, thereby avoiding the waste of water resources.

[0019] (3) The present invention blows atomized water through a spray assembly, which can prevent the atomized water from scattering everywhere and avoid the high-pressure water from violently impacting the side of the precast beam. This allows the atomized water to be concentrated and uniformly contacted with the side of the precast beam, thereby increasing the amount of atomized water in contact with the side of the precast beam and improving the efficiency of curing the side of the precast beam.

A first mist is provided on the outer surface of the top two edges of the extended spray pipe 11. The spray nozzle 12 and the upper outer surface of the limiting sleeve 9 are rotatably engaged with the first drive shaft 10. The outer surfaces of both ends of the first drive shaft 10 are welded with first drive sprockets 7. The bottom end of the extended spray pipe 11 is fixedly connected to the first delivery hose 8. A protective cover 14 is fixedly installed inside the spray assembly 4. A second atomizing nozzle 15 is evenly fixedly installed on the outer edge of one end of the protective cover 14. A second delivery hose 17 is fixedly connected to the bottom of one end of the protective cover 14. A blade 16 is rotatably engaged at the center inside the protective cover 14. One end of the blade 16 is rotatably connected to a universal joint 13. A motor 27 is fixedly installed inside the drive mechanism 5. One end of the motor 27 is fixedly connected to a water pump 25. The bottom of the water pump 25... A vertical pipe 18 is symmetrically arranged in the pump 25. A filter screen 19 is fixedly connected to the bottom outer surface of the vertical pipe 18. A transmission rod 24 is fixedly connected to the center of the side of the pump 25. A limit frame 23 is movably engaged on the outer surface of the transmission rod 24. A second transmission shaft 22 is rotatably engaged on one side of the limit frame 23. A first transmission gear 20 is welded to the outer surface of one end of the second transmission shaft 22. A second transmission gear 21 is welded to the outer surfaces of both the second transmission shaft 22 and the transmission rod 24. A first transmission chain 26 is meshed with the center edges of both sides of the pump 25. A limit frame 32 is fixedly installed inside the drive mechanism 6. A first drive shaft 33 is symmetrically engaged at the bottom of both ends of the limit frame 32. The outer surfaces of both ends of the first drive shaft 33 are welded with second drive sprockets 34, and the outer surfaces of the second drive sprockets 34 are meshed with second drive chains 30. The center of both ends of the top of the limiting frame 32 is welded with support frames 28. The edge of one end of the first drive shaft 33 is welded with a third drive gear 29. The outer surfaces of both ends of the first drive shaft 33 are welded with fourth drive gears 31. The pump 25 has symmetrically opened pump chambers 39 inside. The center of the pump 25 is rotatably connected to the second drive shaft 36. Impellers 35 are fixedly installed on both sides of the middle part of the second drive shaft 36. The top of the pump 25 is symmetrically provided with drain ports 38. The top of the drain ports 38 is rotatably installed with one-way valve plates 37.

[0031] The blade 16 is rotatably connected to one end of the first drive shaft 10 via a universal joint 13. The water pump 25 is rotatably connected to the first drive sprocket 7 via the first drive chains 26 on both sides. The extended spray pipe 11 is fixedly connected to the top of the support frame 28 via the first delivery hose 8 at the bottom. The gear ratio between the first drive gear 20 and the second drive gear 21 is 2:1.

[0032] Through the above technical solution, the blade 16 can be rotatably connected to one end of the first drive shaft 10 via the universal joint 13, and the water pump 25 can be rotatably connected to the first drive sprocket 7 via the first drive chain 26 on both sides. Thus, the motor 27 drives the universal joint 13 to rotate via the first drive chain 26, and the universal joint 13 drives the blade 16 to rotate, thereby pushing the atomized water sprayed from the second atomizing nozzle 15. The extended spray pipe 11 is fixedly connected to the top of the support frame 28 via the first conveying hose 8 at the bottom, thereby enabling the delivery of high-pressure water. The gear ratio between the first drive gear 20 and the second drive gear 21 is 2:1, which can reduce the speed output by the motor 27, thereby ensuring that the precast beam atomizing spray mechanism 2 is slowly transported and operated on the side of the precast beam support base 1.

[0033] The second atomizing nozzle 15 is connected to the second delivery hose 17 at one end of the protective cover 14. The bottom of the protective cover 14 is rotatably connected to the top of the limiting frame 32 through the support frame 28. A hydraulic cylinder is fixedly installed on the bottom outer surface of the limiting sleeve 9, and the bottom end of the extended spray pipe 11 is fixedly connected to the top end of the hydraulic cylinder.

[0034] Through the above technical solution, the second atomizing nozzle 15 is connected to the second delivery hose 17 at one end of the protective cover 14, thereby ensuring that water is delivered to the second atomizing nozzle 15 and sprayed out. Moreover, the bottom of the protective cover 14 is rotatably connected to the top of the limiting frame 32 through the support frame 28, which can support the protective cover 14 and ensure the stability of the protective cover 14. The hydraulic cylinder is fixedly installed on the bottom outer surface of the limiting sleeve 9, and the bottom end of the extended spray pipe 11 is fixedly connected to the top end of the hydraulic cylinder, so that the lifting and lowering of the extended spray pipe 11 can be controlled when the hydraulic cylinder is running.

[0035] The transmission rod 24 is meshed with the first transmission gear 20 through the second transmission gear 21, the second transmission shaft 22 is meshed with the third transmission gear 29 through the second transmission gear 21 on the outer surface, and the first drive shaft 33 is rotatably connected to each other through the second transmission chain 30 and the second transmission sprocket 34 at both ends.

[0036] Through the above technical solution, the transmission rod 24 can be meshed with the first transmission gear 20 through the second transmission gear 21, and the second transmission shaft 22 can be meshed with the third transmission gear 29 through the second transmission gear 21 on the outer surface. Thus, when the motor 27 is running, it can reduce the rotation of the first drive shaft 33. The first drive shafts 33 are rotatably connected by the second transmission chain 30 and the second transmission sprocket 34 at both ends, which can make the two sets of first drive shafts 33 rotate synchronously.

[0037] The two sets of impellers 35 inside the water pump 25 are arranged in opposite directions, and the two sets of one-way valve plates 37 on the top of the impellers 35 are arranged in opposite directions. The impellers 35 are fixedly connected to the center of the end of the motor 27 through one end of the second drive shaft 36.

[0038] Through the above technical solution, the two sets of impellers 35 inside the water pump 25 are arranged in opposite directions, and the two sets of one-way valve plates 37 on the top of the impellers 35 are also arranged in opposite directions. Therefore, when the motor 27 rotates in different directions, it can pump water from the water collection tank. The impellers 35 are fixedly connected to the center of the end of the motor 27 through one end of the second drive shaft 36, which enables the motor 27 to drive the water pump 25 to rotate, thereby pumping water into the precast beam atomizing spray mechanism 2 and the spray assembly 4.

[0039] One end of the transmission rod 24 is fixedly connected to one end of the second drive shaft 36. A torsion spring is symmetrically fixedly connected to the edge of the one-way valve plate 37. The bottom end of the vertical pipe 18 is inserted into the interior of the filter screen 19. Water collection tanks are provided on both sides of the precast beam support base 1. Toothed rails are provided on both sides of the upper surface of the precast beam support base 1.

[0040] Through the above technical solution, one end of the transmission rod 24 is fixedly connected to one end of the second drive shaft 36, which enables the motor 27 to drive the transmission rod 24 to rotate synchronously through the second drive shaft 36, thereby enabling the second transmission gear 21 to drive the third transmission gear 29 to rotate at a reduced speed. Moreover, the torsion springs symmetrically fixedly connected to the edge of the one-way valve plate 37 can reset the one-way valve plate 37 after it flips. The bottom end of the vertical pipe 18 is inserted into the interior of the filter screen 19, which enables the filter screen 19 to filter the water drawn by the vertical pipe 18. Water collection tanks are provided on both sides of the precast beam support base 1, which can collect the downstream water. Furthermore, the toothed rails provided on both sides of the upper surface of the precast beam support base 1 can restrict the movement of the drive mechanism 6.

[0041] A method for operating an automatic spray atomizer for precast beams includes the following steps:

[0042] S1. First, fill the water collection tank with water and ensure that the water level is always higher than the vertical pipe 18. Then, start the motor 27 to drive the drive mechanism 6 to move on the side of the upper surface of the precast beam support base 1. At the same time, the water pump 25 will be driven to run. The water pump 25 will transport the water in the water collection tank to the extended spray pipe 11 and the spray assembly 4 and spray it out through the first atomizing nozzle 12 and the second atomizing nozzle 15.

[0043] S2, wherein the blade 16 will run synchronously with the motor 27, thereby blowing the water mist sprayed by the second atomizing nozzle 15 to the outer surface of the precast beam, while the first atomizing nozzle 12 will spray the water mist on the top surface of the precast beam, thereby playing a role in curing the precast beam.

[0044] S3. Then control the forward and reverse operation of motor 27 so that the outer surface of the precast beam can be sprayed with water mist repeatedly for curing by the precast beam atomizing spraying mechanism 2.

[0045] The working principle of this invention is as follows: First, water is injected into the water collection tank, ensuring that the water level is always higher than the vertical pipe 18. Then, the motor 27 is started. Simultaneously, the water pump 25 is driven to run. The water pump 25 drives the first transmission gear 20 to rotate synchronously via the second transmission gear 21 on the outer surface of the transmission rod 24. The rotation of the first transmission gear 20 causes the second transmission shaft 22 to drive the third transmission gear 29, which is meshed with its outer surface, to rotate synchronously via the second transmission gear 21. When the third transmission gear 29 rotates, it drives the fourth transmission gears 31 at both ends to rotate synchronously. When the fourth transmission gears 31 rotate, the drive mechanism 6 moves laterally on the upper surface of the toothed rails on both sides of the precast beam support base 1. While the drive mechanism 6 moves, the impeller 35 inside the water pump 25 rotates synchronously. When the water pump 25 rotates, it generates negative pressure inside the pump chamber 39, drawing water from the bottom collection tank through the vertical pipe 18. As water enters the pump chamber 39, it forces the one-way valve 37 inside the drain port 38 to flip, allowing high-pressure water to enter the extended spray pipe 11 and the second atomizing nozzle 15 through the first delivery hose 8 and the second delivery hose 17, respectively. Finally, the water is atomized and sprayed out through the first atomizing nozzle 12 and the second atomizing nozzle 15. Simultaneously, when the water pump 25 and motor 27 rotate, they drive the first transmission shaft 10 to rotate synchronously via the first transmission chain 26 and the first transmission sprocket 7. When shaft 10 rotates, it drives blade 16 to rotate synchronously through universal joint 13 at one end. Simultaneously, the rotation of blade 16 generates a strong negative pressure, which blows the water mist sprayed from the second atomizing nozzle 15 until a large amount of water mist is blown to a designated height on the side of the precast beam. At the same time, drive mechanism 6 drives spraying assembly 4 to move laterally, thus enabling lateral spraying of the side of the precast beam. Excess water generated during spraying flows down the side of the precast beam and eventually into the water collection tank, facilitating repeated extraction and recycling by drive mechanism 5. Furthermore, after drive mechanism 6 reaches one end of the precast beam support base 1, it reverses direction, causing impeller 35 to rotate in the opposite direction inside pump chamber 39. During operation, since the two sets of impellers 35 inside the water pump 25 are arranged in opposite directions, different impellers 35 will be used to extract water when the second drive shaft 36 rotates in different directions. This allows the precast beam atomizing spraying mechanism 2 to extract water and perform reciprocating spraying and curing on the sides of the precast beam during reciprocating operation. Furthermore, the extended spray pipe 11 will perform atomizing spraying and curing on the top side of the precast beam through the first atomizing nozzles 12 at both ends of the top. When spraying the sides of the precast beam at different heights, the protective cover 14 can be pulled and deflected at the top of the support frame 28 to adjust the spraying angle of the atomized water. The second transmission gear 21 on the outer surface of the transmission rod 24 meshes with the first transmission gear 20.The second transmission gear 21 on the outer surface of the second transmission shaft 22 meshes with the third transmission gear 29, which slows down the high-speed operation of the motor 27. This causes the third transmission gear 29 to drive the fourth transmission gear 31 at both ends of the first drive shaft 33 to rotate slowly. Simultaneously, the drive mechanism 6 drives the extended spray section 3 and spray assembly 4 at the top to move slowly and uniformly. Therefore, through the coordinated operation of the extended spray section 3, spray assembly 4, and drive mechanism 5, excess water from the spraying can be easily collected and recycled. It also allows for automatic reciprocating atomized spraying of the precast beam side for curing and facilitates the delivery of atomized water to designated locations on the precast beam side for spraying and curing.

All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
