Description

Technical Field

[0001] This invention relates to the field of highway bridge construction technology, and more specifically to a concrete curing device based on highway bridge construction. Background Technology

[0002] Concrete is used in the construction of roads and bridges. After the concrete is poured, it absorbs water during the hardening process. However, the water content of the concrete itself is insufficient to meet the needs of hardening. If it is not cured in time, the concrete will shrink and separate during the hardening process, affecting its strength. To ensure that the concrete has sufficient strength, workers need to cure it. This is usually done by using concrete curing equipment to spray water and laying plastic film to prevent cracks and other problems from appearing on the road.

[0003] However, existing concrete curing equipment cannot simultaneously spray water and lay plastic film. Workers must spray water first and then lay the film, which increases the labor intensity of workers and reduces work efficiency. Furthermore, because the curing equipment does not have a mixing function, the curing agent and water mixed poorly during curing, and the curing agent is prone to sedimentation, which reduces the curing effect on the concrete and makes it difficult to promote its use.

[0004] To address this problem, this application provides a concrete curing device based on highway bridge construction. Summary of the Invention

[0016] Due to the adoption of the above technical solution, the technical progress achieved by this invention compared to the prior art is as follows:

[0017] 1. This invention provides a concrete curing device based on highway bridge construction. Through the combined action of a rotating connecting shaft, a movable connecting bracket, a film conveying roller, and a transmission connecting frame, the rotating connecting shaft is connected to the film placement rod via the transmission connecting frame and the rotating connecting sleeve. When the rectangular mounting plate moves, the rotating connecting shaft drives the film placement rod to rotate through the transmission connecting frame and the rotating connecting sleeve, thus lowering the plastic film. The plastic film is then laid on the surface of the concrete via the film conveying roller, eliminating the need for subsequent laying by workers, reducing the labor intensity of workers while improving work efficiency.

[0018] 2. This invention provides a concrete curing device based on highway bridge construction. Under the combined action of an electric motor, a stirring rotating rod, and a stirring blade, water and curing agent are introduced into the curing water storage tank. The electric motor drives the two stirring rotating rods to rotate, which in turn drives the stirring blade to rotate, stirring the mixture of water and curing agent. This ensures that the water and curing agent are fully mixed, preventing the curing agent from settling and affecting the curing effect on the concrete.

[0019] 3. This invention provides a concrete curing device based on highway bridge construction. Through the combined action of the movable connecting bracket, the film conveying roller, and the second rotating roller, after the movable connecting bracket is lowered, the second rotating roller contacts the surface of the concrete. When passing through some non-horizontal road surfaces, the presence of the second rotating roller will cause the movable connecting bracket to move accordingly, so that the plastic film can be evenly covered on the surface of the concrete, preventing the uneven coverage of the plastic film from causing the moisture to evaporate too quickly and affecting the hardening effect of the concrete.

[0028] The present invention will be further described in detail below with reference to embodiments:

[0029] like Figure 1-7 As shown, the present invention provides a concrete curing device based on highway bridge construction, including a support component 1, a spraying component 2, a film lowering component 3, and a mixing component 4. The spraying component 2 sprays a mixture of water and curing agent onto the surface of the concrete to cure the concrete. The film lowering component 3 lays a plastic film on the surface of the concrete to prevent the water from evaporating too quickly. The mixing component 4 stirs the mixture of water and curing agent to ensure that the water and curing agent are fully mixed.

[0030] like Figure 2-5 As shown, the support assembly 1 includes a rectangular mounting plate 10, a first rotating roller 11, and a rotating connecting shaft 12. The first rotating roller 11 is fixedly mounted at both ends of the rotating connecting shaft 12, which is rotatably mounted at the bottom of the rectangular mounting plate 10. A fixed connecting bracket 14 is fixedly mounted on the top of the rectangular mounting plate 10, and a transmission connecting bracket 35 is provided on the top of the rectangular mounting plate 10. One end of the transmission connecting bracket 35 is fixedly mounted on the outside of the rotating connecting shaft 12, and the other end is fixedly mounted on the outside of the rotating connecting sleeve 37. A mounting bracket 38 is fixedly installed on one side of the mounting bracket 14. A rotating connecting sleeve 37 is rotatably installed inside the mounting bracket 38. One end of the film placement rod 33 is movably connected inside the rotating connecting sleeve 37. The rotating connecting shaft 12 is connected to the film placement rod 33 through the transmission connecting bracket 35 and the rotating connecting sleeve 37. When the rectangular mounting plate 10 moves, the first rotating roller 11 will drive the rotating connecting shaft 12 to rotate, and then the rotating connecting shaft 12 will drive the film placement rod 33 to rotate through the transmission connecting bracket 35 and the rotating connecting sleeve 37.

[0031] like Figure 1 As shown, a traction frame 13 is fixedly installed at one end of the rectangular mounting plate 10. The traction frame 13 connects the rectangular mounting plate 10 to the external traction device, making it easier for the external traction device to pull the device to move.

[0032] like Figure 6 As shown, the spraying assembly 2 is fixedly installed on the outside of the support assembly 1. The spraying assembly 2 includes a curing water tank 20, a liquid level sensor 23, a water pump 26, and a spraying pipe 27. The liquid level sensor 23 is fixedly installed inside the curing water tank 20. The liquid level sensor 23 monitors the liquid level inside the curing water tank 20 and replenishes the liquid when the liquid level inside the curing water tank 20 is low.

[0033] like Figure 1 , Figure 2 , Figure 6 and Figure 7As shown, the curing water tank 20 is fixedly installed on the top of the rectangular mounting plate 10. The top of the curing water tank 20 has a water inlet 21. A rotating cover 22 is rotatably installed on the top of the curing water tank 20, and the rotating cover 22 is located on top of the water inlet 21. A protective cover plate 24 is fixedly installed on the top of the curing water tank 20. One end of the curing water tank 20 has a water outlet 25. A water pump 26 is fixedly installed on the top of the rectangular mounting plate 10. The water pump 26 is connected to the water outlet 25 through a pipe. One end of the spray pipe 27 is fixedly installed inside the water pump 26. The spray pipe 27 is located at the bottom of the rectangular mounting plate 10. A spray head 28 is fixedly installed inside the spray pipe 27. The water pump 26 works to extract the mixture of water and curing agent from the curing water tank 20 and pump it into the spray pipe 27 through the pipe. Then, the mixture is sprayed onto the surface of the concrete through the spray head 28 on the spray pipe 27.

[0034] like Figure 3 and Figure 4 As shown, the film lowering assembly 3 is movably installed on top of the support assembly 1. The film lowering assembly 3 includes a movable connecting bracket 30, a film conveying roller 31, a second rotating roller 32, a film placement rod 33, a transmission connecting frame 35, and a rotating connecting sleeve 37. The movable connecting bracket 30 is rotatably installed on top of the rectangular mounting plate 10. The film placement rod 33 is set on top of the fixed connecting frame 14. The rotating connecting shaft 12 drives the film placement rod 33 to rotate through the transmission connecting frame 35 and the rotating connecting sleeve 37, lowering the plastic film so that the plastic film is laid on the concrete surface by passing through the film conveying roller 31. With the combined action of the rotating connecting shaft 12, the movable connecting bracket 30, the film conveying roller 31, and the transmission connecting frame 35, no further laying by workers is required, reducing the labor intensity of workers and improving work efficiency.

[0035] like Figure 3 and Figure 4 As shown, a bracket connecting rod 34 is rotatably mounted on one side of the fixed connecting frame 14, and the other end of the bracket connecting rod 34 is rotatably mounted on one side of the movable connecting bracket 30. By removing the pin on the side of the movable connecting bracket 30, the bracket connecting rod 34 can be disengaged from the movable connecting bracket 30, allowing the movable connecting bracket 30 to be lowered. During non-working hours, the movable connecting bracket 30 can be retracted via the bracket connecting rod 34, reducing the overall length of the device.

[0036] like Figure 4As shown, the film conveying roller 31 is rotatably installed inside the movable connecting bracket 30, and the second rotating roller 32 is rotatably installed inside the movable connecting bracket 30. After the movable connecting bracket 30 is lowered, the second rotating roller 32 contacts the surface of the concrete. When passing through some non-horizontal road surfaces, the presence of the second rotating roller 32 will cause the movable connecting bracket 30 to move accordingly. Through the combined action of the movable connecting bracket 30, the film conveying roller 31, and the second rotating roller 32, the plastic film can be evenly covered on the surface of the concrete, preventing the uneven coverage of the plastic film from causing the water to evaporate too quickly and affecting the hardening effect of the concrete.

[0037] like Figure 3 , Figure 6 and Figure 7 As shown, the stirring assembly 4 is located inside the spraying assembly 2. The stirring assembly 4 includes a motor 40, a stirring rotating rod 45, and a stirring blade 46. The stirring blade 46 is fixedly installed on the outside of the stirring rotating rod 45. A rotating shaft fixing plate 36 is provided on the top of the fixed connecting frame 14. The rotating shaft fixing plate 36 is located on the outside of the film placement rod 33. The motor 40 is fixedly installed on the top of the curing water storage tank 20. A motor fixing frame 41 is fixedly installed on the top of the curing water storage tank 20. The motor 40 is fixedly installed on the top of the motor fixing frame 41. The stirring rotating rod 45 is fixedly installed on one end of the motor 40 and is rotatably installed inside the curing water storage tank 20. A first transmission pulley 42 is fixedly installed on the outside of the stirring rotating rod 45. A transmission belt 43 is movably connected to the outside of the first transmission pulley 42. The other end of the transmission belt 43 is movably connected to a second transmission pulley 44. Both the transmission belt 43 and the second transmission pulley 44 are located below the protective cover plate 24. The stirring blade 46 is located inside the curing water tank 20. The motor 40 drives the stirring rotating rod 45 to rotate, which causes the first transmission pulley 42 outside the stirring rotating rod 45 to drive the second transmission pulley 44 to rotate via the transmission belt 43. The second transmission pulley 44 then drives another stirring rotating rod 45 inside it to rotate, which in turn drives the stirring blade 46 to rotate. Under the combined action of the motor 40, the stirring rotating rod 45, and the stirring blade 46, the mixture of water and curing agent in the curing water tank 20 is stirred, ensuring that the water and curing agent are fully mixed and preventing the curing agent from settling and affecting the curing effect on the concrete.

[0038] The working principle of this concrete curing equipment based on highway bridge construction will be explained in detail below.

[0039] like Figure 1-7As shown, when using this concrete curing equipment based on highway bridge construction, the rectangular mounting plate 10 is connected to the external traction device via the traction frame 13 at the end of the rectangular mounting plate 10, and the wiring of some components on the rectangular mounting plate 10 is connected. Simultaneously, the rotating cover 22 is opened, and water and curing agent are introduced into the curing water storage tank 20 through the water inlet 21. After the water and curing agent are introduced into the curing water storage tank 20, the motor 40 is driven. The motor 40 drives the stirring rotating rod 45 to rotate, causing the first transmission pulley 42 outside the stirring rotating rod 45 to drive the second transmission pulley 44 to rotate via the transmission belt 43. The second transmission pulley 44 then drives another stirring rotating rod 45 inside it to rotate, which in turn drives the stirring blade 46 to rotate. The motor 40, stirring rotating rod 45, and stirring blade 46 then rotate. Under the combined action, the mixture of water and curing agent in the curing water tank 20 is stirred to ensure that the water and curing agent are fully mixed, preventing the curing agent from settling and affecting the curing effect on the concrete. Then, the plastic film is fixed on the film placement rod 33, and the film placement rod 33 is placed back on the fixed connecting frame 14. One end of the film placement rod 33 is inserted into the rotating connecting sleeve 37. The film placement rod 33 is then fixed on the fixed connecting frame 14 by the rotating shaft fixing pressure plate 36. Then, the pin on the side of the movable connecting bracket 30 is removed to separate the bracket connecting rod 34 from the movable connecting bracket 30. The movable connecting bracket 30 is lowered, and the plastic film is pulled so that one end of the plastic film passes through the two film conveying rollers 31 in the middle of the movable connecting bracket 30, and the end of the plastic film is at the bottom of the film conveying rollers 31 at the end of the movable connecting bracket 30.

[0040] When the device is in operation, it is moved by an external traction device. Simultaneously, a water pump 26 operates, drawing the mixture of water and curing agent from the curing water tank 20 and pumping it into the spraying pipe 27. The mixture is then sprayed onto the concrete surface through the spray nozzles 28 on the spraying pipe 27. During spraying, a level sensor 23 monitors the liquid level inside the curing water tank 20 for timely replenishment. Simultaneously, after the movable connecting bracket 30 is lowered, the second rotating roller 32 contacts the concrete surface. When traversing non-level surfaces, the presence of the second rotating roller 32 causes the movable connecting bracket 30 to move accordingly. Through the combined action of the movable connecting bracket 30, the film conveying roller 31, and the second rotating roller 32, the plastic film can be evenly covered. To prevent uneven coverage of the plastic film on the concrete surface from causing excessive moisture evaporation and affecting the hardening effect of the concrete, and because the rotating connecting shaft 12 is connected to the film placement rod 33 through the transmission connecting frame 35 and the rotating connecting sleeve 37, when the rectangular mounting plate 10 moves, the first rotating roller 11 will drive the rotating connecting shaft 12 to rotate, and then the rotating connecting shaft 12 will drive the film placement rod 33 to rotate through the transmission connecting frame 35 and the rotating connecting sleeve 37, thus lowering the plastic film. The plastic film is then laid on the concrete surface through the film conveying roller 31. With the combined action of the rotating connecting shaft 12, the movable connecting bracket 30, the film conveying roller 31 and the transmission connecting frame 35, no further laying by workers is required, reducing the labor intensity of workers and improving work efficiency.

[0041] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
