Description

Technical Field

[0001] The invention relates to the field of concrete processing, in particular to a green curing device for concrete components. 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 such conditions, artificial curing of concrete is required. Concrete curing methods include the most easily achieved natural curing.

[0003] Natural curing includes watering curing and spraying plastic film curing. The former covers the concrete with straw mats and keeps it moist by sprinkling water frequently. The curing time depends on the type of cement, such as ordinary Portland cement concrete for no less than 7 days and nights. The latter is suitable for high-rise structures and large-area concrete structures that are not easy to be cured by watering. It is to spray the perchlorethylene resin plastic solution on the concrete surface with a spray gun. After the solution evaporates, a thin film is formed on the concrete surface, isolating the concrete from the air, preventing the evaporation of water in the concrete, and ensuring the normal hydration of cement. After the curing is completed, the film will age and fall off by itself.

[0004] Traditional equipment often cannot meet the two requirements of watering and spraying plastic film during natural curing. When watering, the spraying flow rate cannot be adjusted under the premise of ensuring uniformity, and when spraying plastic film for curing, the raw materials cannot be mixed well, and the spraying uniformity cannot be well guaranteed. A person skilled in the art has proposed a green curing device for concrete components to solve the problems raised in the above background. Summary of the invention

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0026] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0027] Example 1: Please refer to Figure 1 and Figure 2 A green maintenance device for concrete components includes a portal frame 1, a walking wheel 2 is fixedly connected to the bottom of the portal frame 1, a water tank 3 is fixedly connected to the top of the inner side of the portal frame 1, a spray box 4 is fixedly connected to the bottom of the water tank 3, the spray box 4 is connected to the water tank 3, a motor 5 is fixedly connected to the side of the portal frame 1, a horizontal driving shaft 6 is fixedly connected to the rotor of the motor 5, and a flow regulating component 7 for adjusting the flow of the spray box 4 is arranged on the outer side of the horizontal driving shaft 6.

[0028] When the present invention is used, clean water is injected into the water tank 3. The concrete components to be cured need to be lined up. During the curing, the device is moved to one end of the concrete components to be cured. Then, the curing can be carried out during the movement of the device. The motor 5 is turned on. The motor 5 rotates to drive the horizontal drive shaft 6 to rotate. During the rotation of the horizontal drive shaft 6, the flow regulating component 7 is driven to a suitable position to adjust the flow. The water tank 3 is connected to the spray box 4. Since the water tank 3 is located above the spray box 4, the two can be directly connected, or they can be connected to the spray box 4 through a pipeline at the bottom of the water tank 3. A valve can be set in the middle of the pipeline to control the water flow. The water in the water tank 3 can flow into the spray box 4 under the action of gravity, or a pump can be used to increase the spraying pressure.

[0029] The flow regulating assembly 7 includes a driving thread 8 arranged on the outer side of the horizontal driving shaft 6, and the driving thread 8 is threadedly connected to a driving block 9 on the outer side. A plurality of rows of spray holes 10 are provided on the spray box 4, and a sliding adjustment plate 11 is slidably provided on the inner side of each row of spray holes 10. The sliding adjustment plate 11 is slidably connected to the spray box 4, and a through hole 32 matching the spray hole 10 is provided on the sliding adjustment plate 11. The ends of the sliding adjustment plates 11 are fixedly connected to a first spring 12, and the sliding adjustment plates 11 are fixedly connected to a driven fixed block 13. During the movement of the driving block 9, the adjacent sliding adjustment plates 11 are driven to slide in sequence through the transverse driving rod 14.

[0030] The flow regulating assembly 7 includes a driving thread 8 which is rotationally driven by a motor 5. During the rotation of the driving thread 8, the driving block 9 is driven to move along the axial direction of the horizontal driving shaft 6, and during the startup process, one of the sliding adjustment plates 11 is driven to move linearly synchronously. When the sliding adjustment plate 11 moves, the through hole 32 opened on its surface will gradually coincide with the spray hole 10, thereby adjusting to a suitable spray flow rate. During the movement of the driving block 9, the driving rod 14 will also be driven to move. The driving rod 14 drives the driven fixed block 13 to move, thereby driving the sliding adjustment plate 11 to move in turn. Under the spring force of the first spring 12, the through holes 32 of each sliding adjustment plate 11 do not coincide with the spray hole 10 when not affected by other external forces, that is, they are in a closed state. As the driving rod 14 applies pressure to the driven fixed block 13 in turn during the movement, the spray holes 10 in different rows will be gradually opened, which can effectively adjust the spray flow rate. In addition, the spray holes 10 in each row can be staggered, so that the clean water sprayed on the concrete component can be more uniform.

[0031] Example 2: Please refer to Figure 2 , Figure 3 and Figure 4This embodiment is improved on the basis of the previous embodiment: a driving gear 15 is fixedly connected to the outside of the horizontal driving shaft 6, a stirring shaft 16 is arranged in the water tank 3, a driven gear 17 is fixedly connected to the outer end of the stirring shaft 16, the driven gear 17 is meshed with the driving gear 15, and a stirring assembly is arranged on the outside of the stirring shaft 16. The stirring assembly includes a cam 18 fixedly connected to the outside of the stirring shaft 16, a mixing plate 19 is slidably connected to the inner wall of the water tank 3, a plurality of connecting holes 20 are evenly arranged on the mixing plate 19, a second spring 21 is fixedly connected to the side of the mixing plate 19 away from the stirring shaft 16, and a push rod 22 is fixedly connected to the side of the mixing plate 19 close to the stirring shaft 16, and the push rod 22 is pressed against the cam 18 under the elastic force of the second spring 21.

[0032] The driving gear 26 can rotate synchronously under the driving action of the motor 5, and then drive the driven gear 25 to rotate. The driven gear 25 drives the stirring assembly to work, so as to stir the curing liquid in the water tank 3. When the curing liquid is clear water, stirring is not required. However, when the curing liquid is cured by using a perchlorethylene resin plastic solution or other solution, the curing liquid needs to be fully stirred to avoid insufficient curing. The driven gear 25 drives the stirring shaft 16 to rotate, and the stirring shaft 16 drives the cam 18 to rotate. During the rotation of the cam 18, the push rod 22 and the cam 18 are against each other, and the mixing plate 19 will reciprocate under the action of the spring force of the second spring 21, so as to stir and mix the curing liquid. The curing liquid will flow through the connecting hole 20, so that the sufficiency is guaranteed. The cam 18 can be set at the head and tail positions of the outer side of the stirring shaft 16, so that the force is even. The stirring column 23 set on the outer side of the stirring shaft 16 can also further improve the uniformity of the curing liquid.

[0033] A plurality of stirring columns 23 are evenly and fixedly connected to the outer side of the stirring shaft 16 .

[0034] Example 3: Please refer to Figure 5 This embodiment is improved on the basis of the previous embodiment: the inner side of the portal frame 1 is rotatably connected with a winding shaft 24, the end of the winding shaft 24 is fixedly connected with a driven pulley 25, the end of the horizontal drive shaft 6 is fixedly connected with a driving pulley 26, the driving pulley 26 and the driven pulley 25 are linked by a transmission belt 27, the outer side of the winding shaft 24 is fixedly connected with a winding roller 28, the winding roller 28 is a hollow structure, and a plurality of locking mechanisms 29 are arranged inside the winding roller 28. The locking mechanism 29 includes a positioning hole 30 opened on the winding roller 28, and a locking wheel 31 is rotatably connected to the eccentric position inside the winding roller 28, and the locking wheel 31 is an eccentric wheel, and the locking wheel 31 cooperates with the positioning hole 30 for locking.

[0035] In the process of using clean water for maintenance, the surface of the concrete structure often needs to be covered with straw mats to play a role in heat preservation. The present application can also simultaneously realize the functions of covering and retracting the straw mats. The straw mats are wound around the outside of the winding shaft 24. When covering, the straw mats will gradually cover the concrete structure while the device is moved. When it needs to be retracted, one end of the straw mat is first inserted into the positioning hole 30, and the locking wheel 31 will lock the straw mat. Since the locking wheel 31 is an eccentric wheel, when the straw mat is subjected to the winding force of the winding roller 28, a relative pulling force will be generated. The locking wheel 31 rotates under the action of friction force. At this time, the extrusion force between it and the positioning hole 30 will increase, thereby realizing the fixation of the end of the straw mat. When the straw mat needs to be loosened, the locking wheel 31 is pushed inward by external force, which will loosen the straw mat.

[0036] The winding roller 28 is located directly below the spray box 4. As the curing process of the device proceeds, the curing liquid will first flow onto the winding roller 28, and during the rotation of the winding roller 28, the curing liquid will be dispersed and evenly sprayed on the surface of the concrete component. The surface of the winding roller 28 is provided with convex ridges along the axial direction, which can avoid slipping when the straw mat is rolled up, and can also make the curing liquid spray more evenly.

[0037] The walking wheel 2 is driven by electricity. The electric drive enables the device to move automatically during the maintenance process. The device is also provided with other corresponding structures, including a water inlet of the water tank 3, and power equipment such as a battery that provides power.

[0038] Working principle: When the present invention is used, clean water is injected into the water tank 3. The concrete components to be cured need to be lined up. During the curing, the device is moved to one end of the concrete component to be cured. Then, the curing can be carried out during the movement of the device. The motor 5 is turned on. The motor 5 rotates to drive the horizontal drive shaft 6 to rotate. During the rotation of the horizontal drive shaft 6, the flow regulating component 7 is driven to a suitable position to adjust the flow. The water tank 3 is connected to the spray box 4. Since the water tank 3 is located above the spray box 4, the two can be directly connected, or they can be connected to the spray box 4 through a pipeline at the bottom of the water tank 3. A valve can be set in the middle of the pipeline to control the water flow.

[0039] The flow regulating assembly 7 includes a driving thread 8 which is rotationally driven by a motor 5. During the rotation of the driving thread 8, the driving block 9 is driven to move along the axial direction of the horizontal driving shaft 6, and during the startup process, one of the sliding adjustment plates 11 is driven to move linearly synchronously. When the sliding adjustment plate 11 moves, the through hole 32 opened on its surface will gradually coincide with the spray hole 10, thereby adjusting to a suitable spray flow rate. During the movement of the driving block 9, the driving rod 14 will also be driven to move. The driving rod 14 drives the driven fixed block 13 to move, thereby driving the sliding adjustment plate 11 to move in turn. Under the spring force of the first spring 12, the through holes 32 of each sliding adjustment plate 11 do not coincide with the spray hole 10 when not affected by other external forces, that is, they are in a closed state. As the driving rod 14 applies pressure to the driven fixed block 13 in turn during the movement, the spray holes 10 in different rows will be gradually opened, which can effectively adjust the spray flow rate. In addition, the spray holes 10 in each row can be staggered, so that the clean water sprayed on the concrete component can be more uniform.

[0040] The driving gear 26 can rotate synchronously under the driving action of the motor 5, and then drive the driven gear 25 to rotate. The driven gear 25 drives the stirring assembly to work, so as to stir the curing liquid in the water tank 3. When the curing liquid is clear water, stirring is not required. However, when the curing liquid is cured by using a perchlorethylene resin plastic solution or other solution, the curing liquid needs to be fully stirred to avoid insufficient curing. The driven gear 25 drives the stirring shaft 16 to rotate, and the stirring shaft 16 drives the cam 18 to rotate. During the rotation of the cam 18, the push rod 22 and the cam 18 are against each other, and the mixing plate 19 will reciprocate under the action of the spring force of the second spring 21, so as to stir and mix the curing liquid. The curing liquid will flow through the connecting hole 20, so that the sufficiency is guaranteed. The cam 18 can be set at the head and tail positions of the outer side of the stirring shaft 16, so that the force is even. The stirring column 23 set on the outer side of the stirring shaft 16 can also further improve the uniformity of the curing liquid.

[0041] In the process of using clean water for maintenance, the surface of the concrete structure often needs to be covered with straw mats to play a role in heat preservation. The present application can also simultaneously realize the functions of covering and retracting the straw mats. The straw mats are wound around the outside of the winding shaft 24. When covering, the straw mats will gradually cover the concrete structure while the device is moved. When it needs to be retracted, one end of the straw mat is first inserted into the positioning hole 30, and the locking wheel 31 will lock the straw mat. Since the locking wheel 31 is an eccentric wheel, when the straw mat is subjected to the winding force of the winding roller 28, a relative pulling force will be generated. The locking wheel 31 rotates under the action of friction force. At this time, the extrusion force between it and the positioning hole 30 will increase, thereby realizing the fixation of the end of the straw mat. When the straw mat needs to be loosened, the locking wheel 31 is pushed inward by external force, which will loosen the straw mat.
