Description

Technical Field

[0001] The invention relates to the technical field of concrete, and in particular to a device and method for maintaining concrete during highway construction. Background Art

[0002] Concrete curing is to artificially create certain humidity and temperature conditions so that the newly poured concrete can harden and increase its strength normally or accelerate its hardening. The reason why concrete can gradually harden and increase its strength is the result of cement hydration, and cement hydration requires certain temperature and humidity conditions. If the surrounding environment does not have these conditions, artificial curing of concrete is required.

[0003] Concrete is a non-homogeneous brittle material, composed of aggregate, cement stone, gas and water retained therein. Under the conditions of temperature and humidity changes, it hardens and produces volume deformation. Due to the inconsistent deformation of various materials, they constrain each other and produce initial stress (tensile stress or shear stress), causing invisible micro cracks to appear between the bonding surface of aggregate and cement stone or between the cement stone itself. The distribution of these micro cracks is irregular and discontinuous, but under the action of load or further temperature difference and shrinkage, the cracks begin to expand and gradually connect with each other, resulting in larger cracks visible to the naked eye (generally the width of cracks visible to the naked eye is 0.03-0.05mm).

[0004] Among the existing highway concrete maintenance methods, most of them adopt the method of spraying curing agents, which is a relatively simple form and cannot deal with cracks or bulges produced in the concrete, thereby reducing the maintenance efficiency and quality of the concrete structure.

[0012] A piston plate is used to generate pressure in a solvent box to spray curing agent on concrete. Furthermore, the solvent box is divided into an air cavity and a solvent cavity by the piston plate. The air cavity is connected to a rolling moving roller via an air pipe. The air pipe is rotatably connected to the shaft end of the rolling moving roller via a sealed bearing. The nozzle is connected to the solvent cavity via a one-way booster valve.

[0014] In order to ensure that the pressure plate drives the piston plate and the rocker arm to rise and fall continuously, and at the same time prevent the curing agent from precipitating in the solvent chamber and affecting the quality of the curing agent, further, an elastic jacking assembly is arranged in the solvent chamber, including two groups of mounting frames and a rotating shaft movably arranged between the two groups of mounting frames, pulleys are fixed at both ends of the rotating shaft, the pulley is slidably installed in the mounting frame, and both ends of the pulley are rotatably connected to sliding brackets, a third spring is connected between the sliding bracket and the mounting frame, a wave wheel is fixedly installed on the surface of the rotating shaft, and the surface of the rotating shaft is rotatably connected to an axis frame, the axis frame is pinned with a linkage plate through an ear plate, and pressure wheels are rotatably installed at both ends of the axis frame.

[0023] In this embodiment, a rolling moving roller 2 is arranged at the bottom of the moving frame 1, and the rolling moving roller 2 is used to drive the moving frame 1 and the maintenance structure arranged on the moving frame 1 to move on the road.

[0024] A compaction assembly for filling cracks in concrete roads, the compaction assembly includes an impact block 15 with vertical reciprocating motion, the impact block 15 is slidably installed in a mobile frame 1, the compaction assembly also includes a support plate 16, the bottom surface of the support plate 16 is symmetrically connected to two groups of guide rods 9, the bottom end of the guide rod 9 is connected to a lifting plate 14, the impact block 15 is fixedly installed below the lifting plate 14, and a clearance groove 17 is opened in the support plate 16.

[0025] In this embodiment, the lifting plate 14 is used to drive the impact block 15 to act vertically and reciprocatingly on the concrete surface during the movement of the mobile frame 1, so as to compact the cracks and protrusions generated in the concrete. The guide rod 9 is used to guide the lifting plate 14 to improve the stability of the reciprocating lifting structure of the impact block 15.

[0026] A driving assembly is arranged on the top of the impact block 15, and the driving assembly includes a motor 4 and a rocker arm 5 fixedly mounted on the output shaft end of the motor 4, a connecting rod 6 is pinned at one end of the rocker arm 5, and the connecting rod 6 is connected to a connecting block 8 through a pin shaft, a fixing plate 7 is fixedly connected to the bottom of the connecting block 8, the fixing plate 7 and the guide rod 9 are slidably connected, and a first spring 10 is connected between the fixing plate 7 and the lifting plate 14.

[0027] In this embodiment, the motor 4 is started, and the output shaft end of the motor 4 is fixedly connected with the rocker arm 5. The rotation of the rocker arm 5 drives the connecting block 8 at one end of the connecting rod 6. The connecting block 8 is fixedly connected to the fixed plate 7. The fixed plate 7 drives the lifting plate 14 to move up and down along the guide rod 9 through the lifting rod 11, thereby realizing the driving of the impact block 15 for compaction.

[0028] Two sets of lifting rods 11 are symmetrically installed on the bottom surface of the fixed plate 7. The lifting rods 11 are slidably connected to the lifting plate 14, and a limiting plate 13 is fixedly installed on the bottom end of the lifting rod 11. A second spring 12 is connected between the lifting plate 14 and the limiting plate 13 and located on the surface of the lifting rod 11.

[0029] In this embodiment, a first spring 10 and a second spring 12 are respectively provided to provide a buffer force for the entire compacting assembly, thereby preventing the impact block 15 from damaging the device itself by reducing the reaction force during the compaction of concrete.

[0030] The spray assembly is used for spraying curing agent on concrete, the spray assembly is transmission-connected with the driving assembly, and the spray assembly includes a solvent box 18 and a nozzle 20 connected to the bottom of the solvent box 18. Specifically, a piston plate 23 is provided in the solvent box 18, and two groups of piston rods 22 are connected to the piston plate 23. The solvent box 18 is divided into an air cavity 24 and a solvent cavity 25 by the piston plate 23, and the nozzle 20 is connected to the solvent cavity 25 through a one-way booster valve 21.

[0031] In this embodiment, the solvent box 18 is divided into an air cavity 24 and a solvent cavity 25 by a piston plate 23, the nozzle 20 is connected to the solvent cavity 25, the solvent cavity 25 is filled with a curing agent, the piston plate 23 moves downward, squeezes the solvent cavity 25, and sprays the curing agent onto the concrete through the nozzle 20.

[0032] The piston rod 22 extends to the outside of the solvent box 18 and is connected to the pressing plate 19 . The pressing plate 19 and the swing rod 5 are closely arranged.

[0033] It should be noted that the pressure plate 19 connected to the top of the piston plate 23 is fitted under the rocker arm 5. The rocker arm 5 is driven to rotate by the motor 4. Since the rocker arm 5 is an eccentric structure, it can push the pressure plate 19 to drive the piston plate 23 to move downward. At the same time, an elastic lifting component is provided in the solvent chamber 25 to lift the piston plate 23, and then the rocker arm 5 presses down the pressure plate 19, thereby realizing the reciprocating vertical movement of the piston plate 23.

[0034] Specifically, the elastic lifting assembly includes two groups of mounting frames 34 and a rotating shaft 30 movably arranged between the two groups of mounting frames 34, pulleys 35 are fixed at both ends of the rotating shaft 30, the pulley 35 is slidably installed in the mounting frame 34, and both ends of the pulley 35 are rotatably connected to sliding brackets 31, a third spring 32 is connected between the sliding bracket 31 and the mounting frame 34, a wave wheel 33 is fixedly installed on the surface of the rotating shaft 30, and the surface of the rotating shaft 30 is rotatably connected to the shaft frame 28, the shaft frame 28 is pinned to the linkage plate 26 through the ear plate 27, and pressure wheels 29 are rotatably installed at both ends of the shaft frame 28.

[0035] In this embodiment, when the rocker arm 5 pushes the pressure plate 19 to drive the piston plate 23 to move downward until it is in contact with the linkage plate 26, the linkage plate 26 pushes the two groups of rotating shafts 30 downward to slide to both sides, and the sliding bracket 31 squeezes the third spring 32. When the eccentric rotation force of the rocker arm 5 disappears, the third spring 32 is reset, and the two groups of rotating shafts 30 move closer, lifting the linkage plate 26 upward, thereby pushing the piston plate 23 upward, so that the rocker arm 5, the pressure plate 19 and the linkage plate 26 always remain in contact, forming a piston movement, thereby realizing the function of spraying the curing agent.

[0036] It should be noted that a pressure wheel 29 and a pulsator 33 are provided on the surface of the rotating shaft 30. When the two sets of rotating shafts 30 move to both sides under the downward pressure, the rotation of the pulley 35 on the mounting frame 34 drives the rotating shaft 30 to rotate, and the pulsator 33 is used to mix the curing agent, and the pressure wheel 29 is used to crush the bottom of the solvent box 18 to prevent the curing agent from precipitating in the box body. After the large particles are crushed, the nozzle 20 can also be prevented from being blocked.

[0037] The roller core 3 is configured as a hollow roller structure, the air cavity 24 is connected to the roller core 3 via an air pipe 36, the air pipe 36 is rotatably connected to the shaft end of the rolling moving roller 2 via a sealed bearing, and air holes 41 are opened through the rolling moving roller 2 and the roller core 3.

[0038] In this embodiment, the piston movement is utilized to introduce air flow into the rolling moving roller 2. When the piston plate 23 moves upward, the gas in the air cavity 24 is squeezed, thereby sending the generated air flow into the roller core 3 through the air pipe 36. Since the roller core 3 and the rolling moving roller 2 are provided with air holes 41, the air flow is finally blown to the concrete surface through the air holes 41, so that the curing agent quickly penetrates into the concrete.

[0039] A connecting frame 39 is fixedly connected to one side of the lifting plate 14, a floating shaft 37 is connected to the bottom of the connecting frame 39, bristles 38 are arranged on the surface of the floating shaft 37, and guide blocks 40 are symmetrically arranged on both sides of the moving frame 1, and the connecting frame 39 and the guide blocks 40 are slidably connected.

[0040] Since the road surface is heavily dusty, during the movement of the mobile frame 1 and the rolling roller 2 rolling the concrete, a large amount of dust may stick to its surface as the working time increases, which may affect the maintenance effect of the concrete road. Therefore, the reciprocating motion of the lifting plate 14 is used to drive the connecting frame 39 to slide up and down in the guide block 40, thereby driving the floating shaft 37 to generate friction on the surface of the rolling roller 2, and the brush 38 is used to clean the dust on the surface of the rolling roller 2 in time.

[0041] In the present invention, the equipment is placed on the concrete surface of the highway, and the rolling moving roller 2 is started to drive the moving frame 1 and the compacting components and spraying components provided above to act on the concrete. The motor 4 is started, and the output shaft end of the motor 4 is fixedly connected with the swing rod 5. The rotation of the swing rod 5 drives the connecting block 8 at one end of the connecting rod 6. The connecting block 8 is fixedly connected to the fixing plate 7. The fixing plate 7 drives the lifting plate 14 to move up and down along the guide rod 9 through the lifting rod 11. The concrete is compacted by the impact of the impact block 15, and the cracks and protrusions on the concrete surface are filled and leveled. At the same time, the motor 4 drives the eccentrically arranged swing rod 5 to rotate, and the pressure plate 19 is arranged under the swing rod 5. The swing rod 5 is driven to rotate by the motor 4. Since the swing rod 5 is an eccentric swing rod, it can push the pressure plate 19 to drive the piston plate 23 to move downward. At the same time, an elastic lifting component is arranged in the solvent chamber 25 to lift the piston plate 23, and then the swing rod 5 presses down the pressure plate 19, thereby realizing the reciprocating vertical movement of the piston plate 23. When the swing rod 5 pushes the pressure plate 19 to drive the piston plate 23 to move downward until it fits with the linkage plate 26, the linkage plate 26 pushes the two sets of rotating shafts 30 downward to slide to both sides, and the sliding bracket 31 squeezes the third spring 32. When the eccentric rotation force of the swing rod 5 disappears, the third spring 32 is reset, and the two sets of rotating shafts 30 are brought together to lift the linkage plate 26 upward, thereby pushing the piston plate 23 upward, so that the swing rod 5, the pressure plate 19 and the linkage plate 26 always keep in contact, forming a piston movement, and realizing the function of spraying the curing agent; The surface of the rotating shaft 30 is provided with a pressing wheel 29 and a pulsator 33. When the two sets of rotating shafts 30 are moved to both sides by downward pressure, the rotation of the pulley 35 on the mounting frame 34 drives the rotating shaft 30 to rotate, and the pulsator 33 is used to mix the curing agent, and the pressing wheel 29 is used to roll the bottom of the solvent box 18 to prevent the curing agent from precipitating in the box. After rolling large particles, the nozzle 20 can also be prevented from being blocked. The piston movement is used to introduce air into the rolling roller 2. When the piston plate 23 moves upward, the gas in the air cavity 24 is squeezed, so that the generated air flow is sent into the roller core 3 through the air pipe 36. Since the roller core 3 and the rolling roller 2 are penetrated by air holes 41, the air flow is finally blown to the concrete surface through the air holes 41, so that the curing agent quickly penetrates into the concrete.

[0042] A method comprising the following steps: Step 1: Place the device on the concrete surface of the highway, start the motor 4, and drive the connecting block 8 and the lifting plate 14 through the swing rod 5 and the connecting rod 6 in turn, thereby driving the impact block 15 to rise and fall at the bottom of the device, so as to compact the concrete; Step 2: The eccentrically arranged swing rod 5 is rotated on the top of the pressing plate 19, so that the piston plate 23 in the solvent box 18 is driven to reciprocate by pressing the pressing plate 19 downward; Step 3: When the piston plate 23 moves downward, the curing agent in the solvent chamber 25 is sprayed onto the concrete through the nozzle 20; Step 4: The curing device uses the rolling roller 2 to move on the concrete surface to further roll the concrete sprayed with the curing agent. At the same time, the air cavity 24 of the piston plate 23 supplies air to the roller core 3 through the air pipe 36. The air flow is discharged through the rolling roller 2 to quickly penetrate the concrete sprayed with the curing agent.

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
