Description

Technical Field

[0001] The invention relates to the technical field of precast beam maintenance, and in particular to an automatic spraying maintenance system and method for a precast beam yard. Background Art

[0002] In the superstructure of the bridge, the small box girder is an assembled structure, which is easy to realize mechanized and factory-based construction. As a mature construction method, the box girder prefabrication process accounts for more than 70% of the use in highway and railway bridge projects, and is widely recognized by designers and constructors. From the perspective of maintenance technology, prefabricated beam yards usually adopt automatic spray maintenance. Spray maintenance uses spray equipment to spray water mist on the surface of the prefabricated beam to keep the concrete moist, thereby avoiding cracks and insufficient strength caused by too fast drying of the surface, thereby improving the strength and durability of the prefabricated beam.

[0003] In the prior art, such as Chinese patent publication number: CN216238032U, an automatic spray maintenance device for a highway bridge prefabricated beam yard is disclosed, including a dust suction component and a spray component, the dust suction component includes a frame, a support platform is fixed on the top of the frame, a first motor is fixed on the top of the support platform, a driving gear is provided at the output end of the first motor, a driven gear is engaged on the surface of the driving gear, a steering shaft runs through the interior of the driven gear, and a rotating rod is fixed on the surface of the steering shaft. The dust suction component is used to absorb dust from the road surface, and the spray component is used to spray water for road surface maintenance. The dust is absorbed by the dust suction component to reduce the dust on the road surface, thereby ensuring that the sprayed water reaches the road surface, avoiding the sprayed water being absorbed by the dust and affecting the actual maintenance effect of the road surface, and the dust is sucked into the dust collecting chamber through the dust suction channel, which can reduce the dust on the road surface before spraying and ensure the spray maintenance effect of the highway road surface.

[0004] In the existing automatic sprinkler curing system for precast beam yards, during use, a large number of sprinkler pipes are generally provided. When spraying the top surface of the precast beam, a large area can be sprayed. When spraying the edge of the top surface of the precast beam, the side sprinkler sprays the edge of the top surface of the precast beam, and other sprinkler heads will spray the places that have been sprayed again, resulting in a large amount of water resource waste and excessive wetting of certain areas. The uneven wetting state will affect the curing effect of the concrete, resulting in inconsistent concrete strength development and even cracks, which will affect the quality of the precast beam.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. When the present invention is used, the electromagnetic valves in the middle and on one side are closed, the booster pump is started, and water is transported to the water delivery pipe, the U-shaped pipe and the fixed pipe through the pumping pipe. Then the water enters the unobstructed diversion pipe, and water is sprayed out through the corresponding spray head and the regulating spray head to spray and maintain the edge of the top surface of the prefabricated beam. At the same time, the first segmented pipe in the middle and the other second segmented pipe cannot pass water normally. Under the action of the spray maintenance component, it is divided into three groups of spray areas. When the three electromagnetic valves are all in the open state, the spray head and the regulating spray head can work at the same time, and the spray coverage area is large. When only one electromagnetic valve on the side is opened, part of the regulating spray head and part of the spray head work, and the edge of the top surface of the prefabricated beam can be sprayed to avoid spraying again on the place that has been sprayed, thereby reducing the waste of water resources. When only the middle electromagnetic valve is opened, local targeted spraying can be carried out through the middle spray head, which is more flexible and can achieve more uniform moisture distribution according to the maintenance needs of different areas, which is beneficial to improving the maintenance quality of concrete.

[0027] 2. When the present invention is used, the first forward and reverse motor on the side is started to drive the rotating rod and the adjusting plate to rotate slightly, and further drive the two adjusting nozzles to rotate slightly. Under the connection of the telescopic tube, the two adjusting nozzles are slightly tilted toward the direction of the edge of the top surface of the prefabricated beam, so that the adjusting nozzles can cover a wider area at the edge of the top surface of the prefabricated beam, reduce dead angles, better spray the edges, and improve the maintenance effect.

[0028] 3. When the present invention is used, the second forward and reverse motor is started to drive the detection plate and the camera to rotate ninety degrees to shoot the spraying condition of the top surface of the precast beam. When the top surface of the precast beam is photographed to have low-lying water accumulation, the PLC controller will control the prompt light to start, prompting the staff that there is water accumulation on the top surface of the precast beam. Then the staff pushes the equipment to move the water accumulation treatment component to the water accumulation place, and then starts the electric push rod to push the cleaning plate to move downward, and the accumulated water is absorbed by the water-absorbing sponge to avoid water accumulation in the low-lying areas of the top surface of the precast beam, causing local excessive wetting. When the cleaning plate moves upward and resets, the bottom ends of the two air outlet pipes enter the two air holes respectively, and the fan is started to blow air into the cleaning plate through the air outlet pipe, air supply pipe, air outlet pipe and air hole, so that the water absorbed by the water-absorbing sponge evaporates quickly, which is convenient for the subsequent absorption of other accumulated water.

The outer surface of each of the first and second segmented pipes 209 and the outer surfaces of the two second segmented pipes 209 and the two second segmented pipes 209 are fixedly connected with a second spray pipe 213, and the bottom ends of the two second spray pipes 213 and the three first spray pipes 210 are fixedly connected with a spray head 214.

Each adjacent two adjusting nozzles 217 of the four adjusting nozzles 217 form a group. The outer surface of the first segmented pipe 209 and the outer surfaces of the two second segmented pipes 212 are fixedly installed with two fixing hoops 211. Each fixing hoop 211 is bolted to the bottom of the base frame 101, the bottom of the booster pump 201 is bolted to the top of the mobile seat 102 near the water tank 202, the water tank 202 is bolted to the top of the mobile seat 102, the top of the water tank 202 is fixedly connected with a water inlet pipe 203, one end of the water inlet pipe 203 extends to the top of the workbench 104, the tops of the two fixing plates 218 are fixedly installed with mounting plates 219 near both sides, the tops of the four mounting plates 219 are fixedly installed at the bottom of the base frame 101, and the outer surfaces of the two adjustment plates 221 are movably embedded in the inside of the two fixing plates 218. ;

[0042] In this embodiment, when in use, the touch controller 107, the prompt light 108, the PLC controller 109, the boost pump 201, the first forward and reverse motor 222, the solenoid valve 224, the electric push rod 301, the second forward and reverse motor 305, the camera 307, the fan 308 and the battery 110 are electrically connected, and the battery 110 is used to power other devices. The touch controller 107 can send corresponding operation instructions to the PLC controller 109, and the PLC controller 109 starts the corresponding device to turn on or off according to the received operation instructions. The water inlet pipe 203 is connected to the external water supply pipe, and the water source is transported to the water tank 202 through the water inlet pipe 203. Push rods are installed on the sides of the base frame 101 and the protective plate 103, such as Figure 1As shown, it is convenient for the staff to push the entire spray equipment to move. The three solenoid valves 224 are all in the open state. The push rod pushes the base frame 101, the movable seat 102 and the protective plate 103 to move, thereby driving the spray maintenance component 2 and the accumulated water treatment component 3 to move. The booster pump 201 is started by the touch controller 107, and the water in the water tank 202 is pumped to the water delivery pipe 205, the U-shaped pipe 206 and the fixed pipe 207 in sequence with the help of the pumping pipe 204. Then, the water is transported to the first segmented pipe 209 and the two second segmented pipes 212 in sequence through the three diversion pipes 208, and then enters the three first spray pipes 210, the two second spray pipes 213, the four connecting pipes 215 and the four telescopic pipes 216, and finally passes through the five spray pipes. The sprinkler head 214 and the four regulating sprinkler heads 217 spray and maintain the top surface of the precast beam. When the spraying of the middle of the top surface of the precast beam is completed, when it is necessary to spray the edge of the top surface of the precast beam, the two solenoid valves 224 in the middle and on the side are closed (according to the actual situation, you can choose to close any one of the two solenoid valves 224 on the side, so that the two solenoid valves 224 on the side remain in an open state and the other closed state), and the solenoid valve 224 on the other side is still in an open state. At this time, after the booster pump 201 delivers water to the fixed pipe 207, since two of the solenoid valves 224 are in a closed state, the water in the two shunt pipes 208 cannot flow, and the water enters the unobstructed shunt pipe 208, and then enters Into one of the second segmented pipes 212, and through the corresponding second spray pipe 213, connecting pipe 215, telescopic pipe 216, spray head 214 and regulating spray head 217, water is sprayed to the edge of the top surface of the prefabricated beam for spray maintenance. At the same time, the middle first segmented pipe 209 and the other second segmented pipe 212 cannot pass water normally. Under the action of the spray maintenance component 2, it is divided into three groups of spray areas. When the three solenoid valves 224 are all in the open state, the spray head 214 and the regulating spray head 217 can work at the same time, and the spray coverage area is large. When only one solenoid valve 224 on the side is opened, part of the regulating spray head 217 and part of the spray head 214 work, and the edge of the top surface of the prefabricated beam can be sprayed to avoid The places that have been sprayed can be sprayed again to reduce the waste of water resources and avoid excessive spraying in certain areas. When only the middle solenoid valve 224 is opened, local targeted spraying can be carried out through the middle spray head 214, which is more flexible and can achieve more uniform moisture distribution according to the maintenance needs of different areas, which is beneficial to improving the maintenance quality of concrete. It solves the problem that when the automatic spraying maintenance system sprays the edge of the top surface of the precast beam, the side spray heads spray the edge of the precast beam, while other spray heads will spray the places that have been sprayed again, causing a large amount of water resources to be wasted, and some areas will be overly moistened, affecting the maintenance effect of the concrete, resulting in inconsistent concrete strength development and affecting the quality of the precast beam.

Under the connection of the telescopic tube 216, the two adjusting nozzles 217 are slightly tilted toward the outside direction of the protective plate 103, that is, toward the direction of the edge of the top surface of the prefabricated beam, so that the adjusting nozzle 217 can cover a wider area at the edge of the top surface of the prefabricated beam, reduce dead angles, better spray the edge, and improve the curing effect. The rotation directions of the output ends of the two first forward and reverse motors 222 are opposite. The two first forward and reverse motors 222 can drive the adjusting nozzles 217 on both sides to rotate to the outside of the two sides of the protective plate 103 respectively, thereby achieving the effect of adjusting the spraying direction.

At this time, the camera 307 faces the top surface of the prefabricated beam, and the spraying condition of the top surface of the prefabricated beam is photographed by the camera 307, and the photographed image is transmitted to the PLC controller 109 through an electrical signal for identification and comparison. When the presence of low-lying water accumulation on the top surface of the prefabricated beam is photographed, the PLC controller 109 will control the prompt light 108 to start, prompting the staff that there is water accumulation on the top surface of the prefabricated beam, and then the staff pushes the equipment to move, so that the water accumulation treatment component 3 moves to the water accumulation, and then starts the electric push rod 301 to push the cleaning plate The cleaning plate 302 moves downward, thereby pushing the water-absorbing sponge 303 to move downward and contact the top surface of the precast beam, and the accumulated water is absorbed by the water-absorbing sponge 303. Then the electric push rod 301 pulls the cleaning plate 302 and the water-absorbing sponge 303 to move upward and reset, so as to avoid water accumulation in the low-lying areas of the top surface of the precast beam, causing local excessive wetting and affecting the performance of the concrete. When the cleaning plate 302 moves upward and resets, the bottom ends of the two air outlet pipes 311 enter the two air holes 312 respectively, and the fan 308 is started to transport the wind to the air outlet pipe 309 and the air supply pipe 310, and then the wind is blown into the cleaning plate 302 through the air outlet pipe 311 and the air hole 312. By continuously blowing air to the water-absorbing sponge 303, the water absorbed in the water-absorbing sponge 303 evaporates quickly, thereby accelerating the drying speed of the water-absorbing sponge 303 and facilitating the subsequent absorption of other accumulated water.

[0047] The use method and working principle of the present invention are as follows: the base frame 101, the movable seat 102 and the protective plate 103 are pushed by the push rod to move, thereby driving the spray curing component 2 and the water accumulation treatment component 3 to move, and the booster pump 201 is started by the touch controller 107, and the water in the water tank 202 is pumped to the water delivery pipe 205, the U-shaped pipe 206 and the fixed pipe 207 in sequence by means of the pumping pipe 204, and then the water is transported to the first segmented pipe 209 and the two second segmented pipes 212 in sequence through the three branch pipes 208, and then enters the three first spray pipes 210, the two second spray pipes 213, the four connecting pipes 215 and the four telescopic pipes 216, and finally the top surface of the prefabricated beam is sprayed and cured through the five spray heads 214 and the four adjusting spray heads 217. After the spraying is completed at the middle of the top surface of the precast beam, when it is necessary to spray the edge of the top surface of the precast beam, the two solenoid valves 224 in the middle and on the side are closed, and the solenoid valve 224 on the other side is still in the open state. At this time, after the booster pump 201 transports water to the fixed pipe 207, since two of the solenoid valves 224 are in the closed state, the water in the two branch pipes 208 cannot flow, and then the water enters the unobstructed branch pipe 208, and then enters one of the second segmented pipes 212, and sprays water through the corresponding second spray pipe 213, connecting pipe 215, telescopic pipe 216, spray head 214 and adjusting nozzle 217 to spray and maintain the edge of the top surface of the precast beam. At the same time, the middle first segmented pipe 209 and the other second segmented pipe 214 are connected to the second segmented pipe 212. The segment pipe 212 cannot pass water normally. Under the action of the spray maintenance component 2, it is divided into three groups of spray areas. When the three solenoid valves 224 are all in the open state, the spray head 214 and the regulating spray head 217 can work at the same time, and the spray coverage area is large. When only one solenoid valve 224 on the side is opened, part of the regulating spray head 217 and part of the spray head 214 can work, and the edge of the top surface of the prefabricated beam can be sprayed to avoid re-spraying of the already sprayed area, reduce water resource waste, and avoid excessive spraying in certain areas. When only the middle solenoid valve 224 is opened, local targeted spraying can be carried out through the middle spray head 214, which is more flexible and can achieve more uniform moisture distribution according to the maintenance needs of different areas. In order to improve the maintenance quality of concrete, the first forward and reverse motor 222 on the side is started to drive the rotating rod 223 to rotate slightly, and drive the adjusting plate 221 to rotate slightly inside the fixed plate 218, and further drive the two adjusting nozzles 217 to rotate slightly. Under the connection of the telescopic tube 216, the two adjusting nozzles 217 are slightly tilted toward the outside direction of the protective plate 103, that is, toward the direction of the edge of the top surface of the precast beam, so that the adjusting nozzles 217 can cover a wider area at the edge of the top surface of the precast beam, reduce dead angles, and better spray the edge. The second forward and reverse motor 305 is started to drive the detection plate 306 to rotate ninety degrees, so that the camera 307 rotates from the moving seat 102 to the outside. At this time, the camera 307 faces the top surface of the precast beam.The camera 307 is used to capture the spraying condition of the top surface of the precast beam, and the captured image is transmitted to the PLC controller 109 through an electrical signal for identification and comparison. When it is captured that there is low-lying water on the top surface of the precast beam, the PLC controller 109 will control the prompt light 108 to start, reminding the staff that there is water on the top surface of the precast beam. Then the staff pushes the equipment to move the water treatment component 3 to the water accumulation place, and then starts the electric push rod 301 to push the cleaning plate 302 to move downward, and then push the water absorbing sponge 303 to move downward to contact the top surface of the precast beam, and the water absorbing sponge 303 will The accumulated water is absorbed, and then the electric push rod 301 pulls the cleaning plate 302 and the water-absorbing sponge 303 to move upward and reset, so as to avoid water accumulation in the low-lying areas on the top surface of the prefabricated beam, causing local excessive wetting. When the cleaning plate 302 moves upward and resets, the bottom ends of the two air outlet pipes 311 enter the two air holes 312 respectively, and the fan 308 is started to transport the wind to the air outlet pipe 309 and the air supply pipe 310, and then the wind is blown into the cleaning plate 302 through the air outlet pipe 311 and the air hole 312. By continuously blowing air to the water-absorbing sponge 303, the water absorbed in the water-absorbing sponge 303 evaporates quickly, and the drying speed of the water-absorbing sponge 303 is accelerated.

[0048] Among them, the touch controller 107, the prompt light 108, the PLC controller 109, the boost pump 201, the first forward and reverse motor 222, the solenoid valve 224, the electric push rod 301, the second forward and reverse motor 305, the camera 307, the fan 308 and the battery 110 are all existing technologies, and their components and operating principles are all public technologies, which will not be explained in detail here.
