Description

Technical Field

[0001] The present invention relates to the technical field of maintenance equipment, and specifically to an intelligent road surface maintenance equipment for bridge construction and its working method. Background Art

[0002] After pouring concrete in bridge construction, it is necessary to spray water on the road surface for maintenance to prevent the concrete on the road surface from cracking due to excessive dryness during solidification. Existing road surface maintenance equipment usually uses spraying equipment to spray water on the road surface. A concrete road surface automatic spraying and maintenance device for bridge construction with a patent application number of CN202510013558.1 uses a spraying component to continuously change the spraying height, thereby more precisely controlling the direction and intensity of the water flow, and improving the dust reduction range and effect of the device during bridge construction.

[0003] However, the moisture on the bridge road surface needs to be ensured to a certain extent. The above spraying and maintenance device only controls the sprayed water flow. After the sprayed water reaches a certain amount, it cannot be automatically closed, which easily causes the amount of sprayed water to be too much, resulting in too low strength after concrete hardening, and thus cannot ensure that the humidity is maintained at a certain level during the concrete hardening process. Moreover, the decrease in the water spraying amount easily affects the water flow pressure, making the spraying distance too close, resulting in the problem that the water needs to flow naturally to expand to the road surface, affecting the coverage effect of the road surface. Summary of the Invention

[0004] The present invention provides an intelligent road surface maintenance equipment for bridge construction and its working method, which overcomes the deficiencies described in the background art.

[0005] The technical solution adopted by the present invention to solve its technical problems is: An intelligent road surface maintenance equipment for bridge construction, including a control panel, a maintenance mechanism, and a cabinet door. The cabinet door is hinged to the maintenance mechanism, and the control panel on the maintenance mechanism controls the maintenance mechanism by electrical signals; The maintenance mechanism is provided with a water pipe, a central processor, an electromagnetic valve, a spraying mechanism, a box body, and a water inlet pipe. Several spraying mechanisms are arranged at equal intervals along the water pipe. The central processor is arranged inside the box body. The control panel is electrically connected to the central processor. The water pipe is buried in the road surface, and the upper half of the spraying mechanism is exposed. The upper end of the water pipe is connected to the water inlet pipe in a pipeline manner. The electromagnetic valve is electrically connected to the central processor. Water flows into the spraying mechanism in the water pipe through the water inlet pipe and is sprayed out, and the opening and closing of the water inlet pipe are controlled by the electromagnetic valve. The spraying mechanism is provided with a circuit, and the circuit is connected to the central processor. The central processor controls the opening and closing of the spraying mechanism through the circuit.

[0006] A preferred technical solution: The spraying mechanism is provided with a housing, a spray head, a sensor, a circuit breaker, an adjusting mechanism and a plastic pipe. The housing is arranged on the side of the plastic pipe. The plastic pipe is connected to a water pipe through a pipeline. The interior of the housing consists of a circuit breaker and a sensor. The circuit breaker is externally connected to a circuit and connected to a central processor. The spray head is arranged at the upper end of the plastic pipe. The adjusting mechanism is arranged at a position inside the plastic pipe near the spray head. The sensor is provided with an infrared temperature sensor, and the infrared temperature sensor irradiates the road surface at an angle of 30 degrees. The electrical signal of the sensor controls the opening and closing of the adjusting mechanism.

[0007] A preferred technical solution: The adjusting mechanism is provided with a small hydraulic device, a partition board and a limiting structure. The small hydraulic device is arranged above the partition board. The left side of the limiting structure is arranged at the output end of the small hydraulic device. A circular hole is arranged in the middle of the partition board, corresponding to the central axis position of the limiting structure. The limiting structure moves up and down and abuts against the opening end of the spray head for sealing.

[0008] A preferred technical solution: The limiting structure is provided with a stress rod, a connecting ring, a spherical block, a metal plate, an arc-shaped groove and a convex block. The stress rod and the spherical block are arranged outside the metal plate. The arc-shaped grooves are arranged in a circular array inside the metal plate. The connecting ring is arranged in the middle of the metal plate. The connecting ring is arranged around the convex block, and an "L"-shaped channel is arranged between the convex block and the connecting ring. The stress rod is arranged at the output end of the small hydraulic device. The small hydraulic device horizontally drives the stress rod to move, and makes the spherical block outside the metal plate slide horizontally inside the partition board.

[0009] A preferred technical solution: The spray head is provided with a stress structure, a spray nozzle, a support block and a spray orifice. The stress structure is arranged at the lower middle part of the support block. The support block is arranged at the upper end of the spray nozzle. There are eight spray orifices, which are arranged at an angle of 45 degrees between the support block and the spray nozzle. A hollow channel is arranged in the middle of the spray nozzle. The stress structure elastically moves above the hollow channel in the middle of the spray nozzle.

[0010] A preferred technical solution: The stress structure is provided with a sphere, a spring, a wrapping plate and a bearing. The sphere is limited to slide under the wrapping plate. The bearing is divided into an inner ring and an outer ring, and the inner and outer rings rotate relative to each other. The outer ring is fixed inside the support block. The spring is arranged between the wrapping plate and the inner ring of the bearing. The sphere elastically presses the spring and makes the wrapping plate drive the inner ring of the bearing to rotate.

[0011] Based on the above working method of the intelligent road surface maintenance equipment for bridge construction, the construction method includes the following specific steps: S1: The central processor controls the opening and closing of the solenoid valve, so that water flows from the water inlet pipe into the water pipe, and monitors the temperature at each position according to the infrared temperature sensor in the sensor. When the temperature is relatively high, the electrical signal of the sensor controls the adjusting mechanism to form a larger opening and closing, and controls the opening and closing degree of the adjusting mechanism according to the size of the temperature; S2: The adjacent spray mechanisms are connected by a circuit breaker, and the temperature data of the sensors is collected and transmitted to the central processor. When the adjustment mechanism opens and closes, the small hydraulic device is controlled to lift and lower the limit structure. When the limit structure moves upward, the metal plate slides horizontally at the upper end of the partition through the spherical block, causing the convex block to approach the opening position of the spray head. At this time, the gap between the convex block and the spray head is small, and less water flows through the "L"-shaped channel and the arc-shaped groove of the connecting ring. S3: The water flow impacts the force-bearing structure upward in the hollow channel in the middle of the spray head, causing the sphere to roll on the wrapping plate. And the spring elastically resists the sphere, causing the wrapping plate to rotate following the inner ring of the bearing under the impact of the water flow. At this time, the sphere rotates in multiple directions. S4: When the water flow rate changes, under the elastic pressing of the force-bearing structure, the water flow scatters outward from the gap between the force-bearing structure and the ejection port at a certain pressure.

[0012] Compared with the prior art, the present technical solution has the following advantages: In the present invention, the infrared temperature sensor on the sensor monitors the road surface temperature and controls the opening and closing degree of the adjustment mechanism according to the temperature magnitude, so that the small hydraulic device hydraulically pushes the limit structure to lift and move. After the limit structure lifts and lowers, the gap between the limit structure and... changes, so that the change in the gap causes the amount of water flowing through to change, and adjusts the water flow size according to the temperature change monitored by each spray mechanism, achieving the effect of intelligent adjustment of the water spray volume, ensuring that the humidity is maintained at a certain level during the hardening process of the road surface concrete, and preventing problems such as too low concrete strength of the road surface due to too much or too little water spray volume.

[0013] In the present invention, the water flow surges out from the middle of the nozzle and pushes the sphere to roll inside the wrapping plate. While rolling, it drives the wrapping plate to compress the spring. At the same time of compression, under the action of the water flow, the spring drives the lower wrapping plate to rotate in the bearing, and according to the water flow pressure, the sphere guides the water flow to scatter in eight directions towards the ejection port, achieving the effect of scattering towards the ejection port at a certain pressure after the water flow rate changes, preventing large changes in the pressure of the water flow scattering resulting in too large or too small scattering range, ensuring the stability of the road surface coverage range of the water flow, and preventing problems such as the need for natural flow expansion of the water flow due to too small scattering range.

Specific implementation manner

[0023] As Figures 1 to 7 shown, an intelligent road surface maintenance device for bridge construction is proposed in the present invention, including a control panel 1, a maintenance mechanism 2 and a cabinet door 3. The cabinet door 3 is hinged to the maintenance mechanism 2, and the control panel 1 on the maintenance mechanism 2 controls the maintenance mechanism 2 by electrical signals; The maintenance mechanism 2 is provided with a water pipe 21, a central processing unit 22, a solenoid valve 23, a spray mechanism 24, a box body 25 and a water inlet pipe 26. A plurality of the spray mechanisms 24 are arranged at equal intervals along the water pipe 21. The central processing unit 22 is arranged inside the box body 25. The control panel 1 is electrically connected to the central processing unit 22. The water pipe 21 is buried in the road surface, and the upper half of the spray mechanism 24 is exposed. The upper end of the water pipe 21 is connected to the water inlet pipe 26 in a butt joint manner. The solenoid valve 23 is electrically connected to the central processing unit 22. Water flows into the spray mechanism 24 in the water pipe 21 through the water inlet pipe 26 and is sprayed out, and the opening and closing of the water inlet pipe 26 are controlled by the solenoid valve 23. The spray mechanism 24 is provided with a circuit, and the circuit is connected to the central processing unit 22. The central processing unit 22 controls the opening and closing of the spray mechanism 24 through the circuit.

[0024] Among them, the spraying mechanism 24 is provided with a housing 241, a spray head 242, a sensor 243, a circuit breaker 244, an adjusting mechanism 245 and a plastic pipe 246. The housing 241 is arranged on the side of the plastic pipe 246. The plastic pipe 246 is connected to the water pipe 21 through a pipeline. The interior of the housing 241 is composed of the circuit breaker 244 and the sensor 243. The circuit breaker 244 is externally connected to a circuit and connected to the central processor 22. The spray head 242 is arranged at the upper end of the plastic pipe 246. The adjusting mechanism 245 is arranged at a position inside the plastic pipe 246 near the spray head 242. The sensor 243 is provided with an infrared temperature sensor, and the infrared temperature sensor irradiates the road surface at an angle of 30 degrees. The sensor 243 controls the opening and closing of the adjusting mechanism 245 through an electrical signal.

[0025] Moreover, the infrared temperature sensor on the sensor 243 is exposed on the road surface. When the sensed temperature is relatively high, the road surface is relatively dry; when the sensed temperature is relatively low, the road surface is humid. By monitoring the road surface temperature, the opening and closing of the adjusting mechanism 245 is controlled to adjust the water flow passing through, so as to adjust the humidity of the road surface according to different conditions at each position.

[0026] Among them, the adjusting mechanism 245 is provided with a small hydraulic actuator 11, a partition plate 12 and a limiting structure 13. The small hydraulic actuator 11 is arranged above the partition plate 12. The left side of the limiting structure 13 is arranged at the output end of the small hydraulic actuator 11. A circular hole is provided in the middle of the partition plate 12, and the circular hole corresponds to the central axis position of the limiting structure 13. The limiting structure 13 moves up and down and abuts against the opening end of the spray head 242 for sealing.

[0027] Moreover, a corrugated plate is provided on the upper end of the partition plate 12 near the small hydraulic actuator 11. The corrugated plate is hermetically connected to the position of the limiting structure 13 near the output end of the small hydraulic actuator 11. When the limiting structure 13 moves up and down, the limiting structure 13 slides inside the upper end of the partition plate 12 to limit the up and down movement of the limiting structure 13, facilitating the sealing pressure of the limiting structure 13 against the opening position of the spray head 242, achieving the gap adjustment effect between the limiting structure 13 and the opening position of the spray head 242, and enabling the position where the left side of the limiting structure 13 is connected to the small hydraulic actuator 11 to compress the corrugated plate, ensuring that the upper end of the partition plate 12 isolates the water flow from entering the position of the small hydraulic actuator 11.

[0028] Among them, the limiting structure 13 is provided with a stress rod 131, a connecting ring 132, a ball block 133, a metal plate 134, an arc-shaped groove 135 and a convex block 136. The stress rod 131 and the ball block 133 are arranged outside the metal plate 134. The arc-shaped grooves 135 are arranged in a circular array within the metal plate 134. The connecting ring 132 is arranged in the middle of the metal plate 134. The connecting ring 132 is arranged around the convex block 136, and an "L"-shaped channel is provided between the convex block 136 and the connecting ring 132. The stress rod 131 is arranged at the output end of the small hydraulic actuator 11. The small hydraulic actuator 11 horizontally drives the stress rod 131 to move, and enables the ball block 133 outside the metal plate 134 to horizontally slide inside the partition plate 12.

[0029] Moreover, the convex block 136 is divided into upper and lower parts. The upper part is an inclined cylinder made of rubber and is in a hollow state inside. When the convex block 136 presses against the opening position of the spray head 242, a sealed pressing is achieved under the rubber material of the convex block 136.

[0030] Among them, the spray head 242 is provided with a stress structure 41, a nozzle 42, a support block 43 and a spray opening 44. The stress structure 41 is arranged at the lower middle part of the support block 43. The support block 43 is arranged above the nozzle 42. There are eight spray openings 44, which are arranged at an inclination of 45 degrees between the support block 43 and the nozzle 42. A hollow channel is provided in the middle of the nozzle 42. The stress structure 41 elastically moves above the hollow channel in the middle of the nozzle 42.

[0031] Moreover, in the static state, the stress structure 41 presses against the upper end of the nozzle 42 and covers the hollow channel in the middle of the nozzle 42. And the water surges upward in the hollow channel. When surging, it pushes the stress structure 41, causing a gap to be generated between the spray openings 44 by the stress structure 41, and under the elastic resistance of the stress structure 41, the water generates a certain pressure and scatters outward.

[0032] Among them, the stress structure 41 is provided with a sphere 411, a spring 412, a wrapping plate 413 and a bearing 414. The sphere 411 is limited to slide under the wrapping plate 413. The bearing 414 is divided into inner and outer rings, and the inner and outer rings rotate relative to each other. The outer ring is fixed inside the support block 43. The spring 412 is arranged between the wrapping plate 413 and the inner ring of the bearing 414. The sphere 411 elastically presses against the spring 412 and drives the inner ring of the bearing 414 to rotate by the wrapping plate 413.

[0033] In the present invention, a certain temperature and water spray amount are set through the control panel 1, thereby controlling the opening and closing of the electromagnetic valve 23 for the water inlet pipe 26, so that water flows into the water pipe 21 and is sprayed out from the spraying mechanism 24. During operation, the infrared temperature sensor on the sensor 243 monitors the road surface temperature, and controls the opening and closing degree of the adjusting mechanism 245 according to the temperature. At this time, the small hydraulic device 11 hydraulically pushes the limiting structure 13 to move up and down. At this time, the water flowing into the upper part from the arc-shaped groove 135 and the "L"-shaped channel of the connecting ring 132 flows through the middle of the spray head 242. After the limiting structure 13 moves up and down, the gap between the limiting structure 13 and the spray head 242 changes, so that the amount of water flowing through changes due to the change of the gap, and the water flow size is adjusted according to the temperature change monitored by each spraying mechanism 24, realizing that the water flow remains at a certain humidity when scattered from the spray head 242 to the road surface. If the humidity is too high, the temperature will decrease. When the temperature decreases, the limiting structure 13 moves upward to reduce the water flow through amount or close the water flow, achieving the effect of intelligent adjustment of the water spray amount, ensuring that the humidity is maintained at a certain level during the hardening process of the road surface concrete, and preventing problems such as too low road surface concrete strength caused by too much or too little water spray amount.

[0034] In the present invention, water surges out from the middle of the nozzle 42 and pushes the sphere 411 to roll within the wrapping plate 413. While rolling, it drives the wrapping plate 413 to compress the spring 412. At the same time of compression, under the action of the water flow, the spring 412 drives the lower wrapping plate 413 to rotate within the bearing 414, and guides the water flow in eight directions towards the jet orifice 44 according to the water flow pressure. At this time, under the elastic force of the spring 412, the force-bearing structure 41 generates resistance to the water flow, so that while the water flow is blocked, it presents a certain pressure. When the water flow rate is small, the impact pressure received by the sphere 411 under the elasticity of the spring 412 becomes smaller, and the gap between the force-bearing structure 41 and the jet orifice 44 becomes smaller. When the water flow rate is large, the impact pressure received by the sphere 411 under the elasticity of the spring 412 becomes larger, and the gap between the force-bearing structure 41 and the jet orifice 44 becomes larger, achieving the effect of scattering towards the jet orifice 44 with a certain pressure after the water flow rate changes, preventing large changes in the pressure of the water flow scattering resulting in too large or too small scattering range, ensuring the stability of the road surface coverage range of the water flow, and preventing problems such as the need for natural expansion of the water flow due to too small scattering range.

[0035] Based on the working method of the intelligent road surface maintenance equipment for bridge construction described above, the construction method includes the following specific steps: S1: The central processor 22 controls the opening and closing of the electromagnetic valve 23, so that water flows from the water inlet pipe 26 into the water pipe 21, and monitors the temperature of each position through the infrared temperature sensor in the sensor 243. When the temperature is relatively high, the electric signal of the sensor 243 controls the adjusting mechanism 245 to form a larger opening and closing, and controls the opening and closing degree of the adjusting mechanism 245 according to the temperature. S2: The adjacent spray mechanisms 24 are connected through a circuit breaker 244, and the temperature data of the sensors 243 are collected and transmitted to the central processor 22. When the adjusting mechanism 245 opens and closes, the small hydraulic actuator 11 is controlled to lift the limiting structure 13. When the limiting structure 13 moves upward, the metal plate 134 slides horizontally on the upper end of the partition plate 12 through the spherical block 133, so that the convex block 136 approaches the opening position of the spray head 242. At this time, the gap between the convex block 136 and the spray head 242 is small, and less water flows through the "L"-shaped channel and the arc-shaped groove 135 of the connecting ring 132. S3: The water flow impacts the force-bearing structure 41 upward in the hollow channel in the middle of the spray head 242, and the sphere 411 rolls on the wrapping plate 413. And the spring 412 elastically resists the sphere 411, so that the wrapping plate 413 rotates along with the inner ring of the bearing 414 under the impact of the water flow. At this time, the sphere 411 rotates in multiple directions. S4: When the water flow rate changes, under the elastic pressing of the force-bearing structure 41, the water flow scatters outward from the gap between the force-bearing structure 41 and the ejection port 44 at a certain pressure.

[0036] The above is only a preferred embodiment of the present invention, and thus the scope of implementation of the present invention cannot be limited thereby. That is, equivalent changes and modifications made according to the scope of the present invention patent and the content of the specification should still fall within the scope covered by the present invention.
