Description

Technical Field

[0001] The present invention relates to the field of concrete curing, and particularly to a concrete curing device for building construction. Background Art

[0002] In the field of building construction, concrete curing is a key link to ensure the strength and durability of concrete structures. There are many drawbacks in traditional concrete curing methods.

[0003] During the curing process, the mixing of water and curing agent needs to be operated separately, which increases the overall operation process. It is not only inefficient, but also difficult to accurately control the mixing ratio, resulting in uneven curing effects. At the same time, if the two are mixed in advance, during the non-use period, the mixed liquid is prone to problems such as deterioration and precipitation, causing waste of resources. In addition, there is often floating dust on the construction site ground. If it is not cleaned before curing, the floating dust will adhere to the concrete surface, affecting the full contact between the curing agent and the concrete, and thus reducing the curing quality. Therefore, the above problems need to be considered. Summary of the Invention

[0020] 4. The gas in the high-pressure box is released to the mixing box through the pressure relief valve, increasing the spraying liquid pressure and absorbing heat to cool down, delaying the liquid evaporation, extending the film covering operation window period, and at the same time improving the atomization effect of the atomizing nozzle to ensure the uniform coverage of the liquid on the road surface.

[0021] 5. The rotating shaft drives the rotating pipe to rotate, the sweeping bar sweeps the road surface and cooperates with the air jet disturbance of the second piston cylinder at the front side to achieve double cleaning of mechanical sweeping and airflow dust raising, improving the road surface pretreatment effect and ensuring the adhesion quality of the curing liquid.

[0022] 6. The air pressure in the rotating pipe pushes the piston block to move downward, making the sweeping bar closely fit the ground during operation and automatically lift in the non-working state, avoiding wear caused by long-term friction, extending the service life of the sweeping bar and reducing the maintenance cost.

[0023] In summary, during the actual use process of the curing device, it has a good curing effect, avoids the adverse effects of floating dust on curing, and in addition, the liquid can be separately recovered during the non-operating stage to avoid component deterioration caused by long-term mixing.

Detailed implementation manners

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

[0034] Refer to Figures 1-8, a concrete curing device for building construction, including a base 1. Two storage boxes 3 are symmetrically and fixedly connected to the upper end of the base 1. Feeding ports 4 are arranged at the upper ends of the two storage boxes 3. A pushing frame 7 is installed on the right side of the storage box 3 on the right side. A plurality of moving wheels 2 are installed at the lower end of the base 1. Through the moving wheels 2, the overall device can be moved. This device is for the concrete curing of some roads that already have load-bearing capacity;

[0035] As an implementation manner of the present invention, a cross plate 5 is fixedly connected to the upper ends of the two storage boxes 3 together. A return frame 17 is arranged below the cross plate 5. Tooth surfaces are arranged on the front and rear side walls of the return frame 17. The left side of the first piston plate 19 is fixedly connected to the return frame 17 through a first connecting rod 20. A driving motor 6 is installed at the upper end of the cross plate 5. The output shaft of the driving motor 6 penetrates the cross plate 5 and is fixedly connected to a rotating shaft 15. An incomplete gear 16 is fixedly connected to the outside of the rotating shaft 15. The incomplete gear 16 cooperates with the two tooth surfaces. When the driving motor 6 is started, the incomplete gear 16 will rotate. By this method, using its intermittent meshing with the two tooth surfaces before and after, the return frame 17 can be realized to move left and right reciprocally;

[0036] As an implementation manner of the present invention, it further includes a liquid spraying mechanism. The liquid spraying mechanism includes a second hollow bar 42 fixedly connected to the lower end of the base 1. A plurality of atomizing nozzles 43 are installed at the inner bottom of the second hollow bar 42. A first piston cylinder 18 is installed on the left side of the storage box 3 on the right side. A first piston plate 19 that can slide left and right is arranged in the first piston cylinder 18. The right side space of the first piston cylinder 18 communicates with a third one-way pipe 46. The other end of the third one-way pipe 46 is respectively communicated with the interiors of the two storage boxes 3 through two branch pipes 45. The pipe diameters of the two branch pipes 45 can be designed according to the actual required ratio to ensure equal proportioning. The right side space of the first piston cylinder 18 communicates with a fourth one-way pipe 47. A mixing box 10 is fixedly connected to the upper end of the base 1. The other end of the fourth one-way pipe 47 is communicated with the interior of the mixing box 10. The interior of the mixing box 10 is communicated with the second hollow bar 42 through a liquid spraying pipe 44;

[0037] As an implementation manner of the present invention, the lower end of the rotating shaft 15 penetrates the mixing box 10 and the base 1. A plurality of stirring blades 28 are installed inside the mixing box 10 where the rotating shaft 15 is located. When the mixed liquid enters the mixing box 10, it will be further mixed to improve the actual mixing effect;

[0038] As an embodiment of the present invention, it further includes a sweeping mechanism for cleaning and sweeping the ground. The sweeping mechanism includes a cylindrical groove 32 opened at the lower end of the base 1. An installation plate 33 is installed at the notch of the cylindrical groove 32. A rotating tube 34 is vertically penetrated through the installation plate 33. The rotating tube 34 is rotatably connected to the installation plate 33 through a bearing. The lower end of the rotating tube 34 is sealed. A piston block 38 that can slide up and down is arranged inside the rotating tube 34. The lower end of the piston block 38 is rotatably connected to the inner bottom of the rotating tube 34 through a spring 40. The lower end of the piston block 38 is fixedly connected to a rectangular strip 41. The lower end of the rectangular strip 41 penetrates through the inner bottom of the rotating tube 34 and is fixedly connected to a first hollow strip 35. Two sweeping strips 37 are symmetrically arranged at the lower end of the first hollow strip 35. A plurality of air holes 36 are opened at the inner bottom of the first hollow strip 35. A vertical through groove 39 is commonly penetrated through the rectangular strip 41 and the piston block 38. Pulley 30s are installed on both the rotating tube 34 and the rotating shaft 15. The two pulley 30s are both connected by a transmission belt 31. When the high-pressure gas is ejected from the second one-way tube 12, a relatively large air pressure will enter the inner top of the rotating tube 34. Since the aperture of the vertical through groove 39 is relatively small, after the high-pressure gas enters, a high-pressure body will accumulate at the inner top of the rotating tube 34, pushing the rectangular strip 41, the first hollow strip 35, and the sweeping strip 37 to move downward (the rectangular strip 41, the first hollow strip 35, and the sweeping strip 37 are made of lightweight materials. In the initial state, the spring 40 is not in a slightly compressed state).

[0039] As an embodiment of the present invention, three second piston cylinders 21 are fixedly connected to the right side of the storage box 3 on the left. Second piston plates 22 that can slide left and right are arranged inside the three second piston cylinders 21. The right sides of the plurality of second piston plates 22 are all fixedly connected to second connecting rods 23. The other ends of the plurality of second connecting rods 23 are commonly fixedly connected to a connecting strip 24. The right side of the connecting strip 24 is fixedly connected to the left side of the return frame 17. The left spaces of the three second piston cylinders 21 on the left are all communicated with a first one-way tube 25 and a second one-way tube 12. The other end of the second one-way tube 12 at the front side is communicated with the upper end of the rotating tube 34 through a rotary joint 48. The other end of the second one-way tube 12 in the middle is communicated with the outside.

[0040] As an implementation mode of the present invention, it further includes a pressure feeding mechanism, which is used to improve the liquid spraying uniformity of the liquid spraying mechanism. The pressure feeding mechanism includes a high-pressure box 11 installed at the upper end of the base 1. The other end of the second one-way pipe 12 located at the rear is communicated with the high-pressure box 11. The inner bottom of the high-pressure box 11 is communicated with the mixing box 10 through a pressure relief pipe 13. A pressure relief valve 14 is installed inside the pressure relief pipe 13. The high-pressure box 11 itself has high-pressure gas and is close to the pressure relief threshold of the pressure relief valve 14. After the high-pressure gas is released into the mixing box 10 through the subsequent pressure relief pipe 13, it will increase the water discharge pressure, making the atomization effect of the atomizing nozzle 43 better. In addition, when the high-pressure gas is released, it will absorb heat and cool the sprayed liquid. In this way, when the curing liquid contacts the ground, the temperature is relatively low, and the time to reach the evaporation point is relatively long later, giving the user enough time to perform subsequent film covering treatment. Further, a plurality of heat sinks can be arranged on the surface of the high-pressure box 11 and used in cooperation with a cooling fan to facilitate cooling of the compressed gas, so as to ensure that the temperature is relatively low when it is released;

[0041] As an implementation mode of the present invention, a hollow cavity 27 is provided inside the base 1. An air inlet 29 is opened at the inner bottom of the hollow cavity 27. A filter box 8 is installed at the upper end of the base 1. The right space of the filter box 8 is communicated with the inside of the hollow cavity 27 through a connecting pipe 9. The other ends of the three first one-way pipes 25 are commonly communicated with a main pipe 26. The other end of the main pipe 26 is communicated with the left space of the filter box 8. A one-way valve is installed inside each of the first one-way pipes 25, the second one-way pipes 12, the third one-way pipes 46, and the fourth one-way pipes 47. The flow directions of the one-way valves inside the three first one-way pipes 25 are all from the filter box 8 into the second piston cylinder 21 unidirectionally. The flow direction of the one-way valve inside the second one-way pipe 12 located at the front is from the second piston cylinder 21 into the rotating pipe 34. The flow direction of the one-way valve inside the second one-way pipe 12 located in the middle is from the second piston cylinder 21 discharged to the outside unidirectionally. The flow direction of the one-way valve inside the second one-way pipe 12 located at the rear is from the second piston cylinder 21 into the high-pressure box 11.

[0042] In the present invention, the device is moved to the position of the concrete road surface to be maintained by the moving wheels 2 at the lower end of the base 1. The pushing frame 7 assists manual operation. After positioning, the movement stops. The drive motor 6 is started to drive the rotation of the rotating shaft 15 and the incomplete gear 16. The incomplete gear 16 intermittently meshes with the tooth surfaces on the front and rear side walls of the loop-shaped frame 17, driving the loop-shaped frame 17 to reciprocate left and right. The loop-shaped frame 17 drives the first piston plate 19 to slide left and right in the first piston cylinder 18 through the first connecting rod 20. In cooperation with the third one-way pipe 46, the fourth one-way pipe 47 and the internal one-way valves, a one-way liquid flow can be generated in the two storage boxes 3, the branch pipe 45, the third one-way pipe 46, the first piston cylinder 18 and the mixing box 10. Finally, the liquid will be sprayed out from the liquid spraying pipe 44 into the second hollow strip 42 and finally sprayed out from the atomizing nozzle 43, realizing the mixed spraying of the curing agent and the water body. Only when the device is running, the curing agent will be mixed with the water body and sprayed out. In this way, during the non-use stage, it is convenient to separately recycle the curing agent and the water body, avoiding deterioration. When the water body and the curing agent enter from the branch pipe 45, they will have a relative impact, which can carry out the initial mixing;

[0043] The stirring blades 28 at the lower end of the above-mentioned rotating shaft 15 will also continuously rotate in the mixing box 10 to stir the entering curing liquid and water body, further improving the mixing effect;

[0044] When the loop-shaped frame 17 moves to the right, it drives a plurality of second piston plates 22 to move left and right in the corresponding second piston cylinders 21 through the connecting strip 24 and a plurality of second connecting rods 23; when the second piston plate 22 moves left, a one-way gas flow will be generated at the bottom of the base, the cavity 27, and the filter box 8, and in the second piston cylinder 21 located in the middle. This gas flow can facilitate the subsequent collection of the raised dust, avoiding the dust settlement from affecting the actual maintenance. In addition, it can also suck away the spilled curing agent, avoiding being inhaled by the staff and affecting their health and safety;

[0045] When the second piston plate 22 moves left, the front second piston cylinder 21 will press the gas into the first hollow strip 35, and finally spray out from a plurality of air holes 36 to blow up the dust on the ground. In cooperation with the subsequent adsorption, the dust can be removed. When the rear second piston cylinder 21 moves right, it will press the gas into the high-pressure box 11. When the air pressure inside the high-pressure box 11 increases and reaches the release threshold of the pressure relief valve 14, the high-pressure gas in the high-pressure box 11 is released to the mixing box 10 through the pressure relief pipe 13 and the pressure relief valve 14, increasing the liquid spraying pressure. In addition, the release of the high-pressure gas absorbs heat, reducing the liquid temperature and delaying evaporation, providing sufficient time for subsequent film covering. The release of the high-pressure gas can also increase the pressure for the water body to be pressed out, so that the atomizing pressure sprayed out by the atomizing nozzle 43 is greater, the atomizing effect is better, and it is more evenly distributed on the ground;

[0046] Furthermore, the rotation of the rotating shaft 15 will also drive the rotation of the rotating tube 34 through the pulley 30 and the transmission belt 31. The sweeping bar 37 contacts the ground and rotates with the rotating tube 34 to clean the road surface, making the ejected gas more uniform, and cooperating with the disturbance to achieve a better cleaning effect.

[0047] It should be noted that after the gas discharged from the second one-way tube 12 on the front side enters the rotating tube 34, due to the small aperture of the vertical through groove 39, a relatively large air pressure will accumulate above the piston block 38. This air pressure can push the piston block 38, the rectangular bar 41, the first hollow bar 35 and the sweeping bar 37 downward, compressing the spring 40, so that during use, the sweeping bar 37 contacts the ground more closely. When not in use, the sweeping bar 37 will not contact the ground, avoiding wear of the sweeping bar 37 caused by long-term contact.

[0048] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, making equivalent substitutions or changes, should be covered by the protection scope of the present invention.
