[0002] In the field of building construction, the curing of concrete roads is of crucial importance, and its quality is directly related to the service life and performance of the road surface. A common method for curing concrete road surfaces is to use a water spraying device to spray and cover the newly laid concrete road surface, so that the road surface remains wet. Then, a curing film with a moisture retention effect is laid on the concrete road surface to keep the road surface wet and prevent the rapid evaporation of water, which is beneficial to the curing and solidification of concrete.

Detailed implementation manners

[0038] 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. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] Please refer to Figure 1-13, the present invention provides a technical solution: a concrete curing device, including a traveling mechanism 1, a water tank 2 disposed on the traveling mechanism 1, and a water spraying mechanism 5 disposed at the lower end of the traveling mechanism 1 and connected to the water tank 2, further including:

[0040] A film covering mechanism 3, disposed on the traveling mechanism 1, for covering the concrete road surface after water spraying with a film;

[0041] A film pressing mechanism 4, disposed on one side of the traveling mechanism 1, for pressing the film attached to the concrete road surface;

[0042] A negative pressure member, disposed below the traveling mechanism 1 and connected to the water spraying mechanism 5, for assisting the film to fit with the concrete ground.

[0043] It should be noted that during operation, water is injected into the water tank 2, then the film covering mechanism 3 is installed on the traveling mechanism 1, and then the water spraying mechanism 5 is turned on to evenly spray the water source on the concrete surface. Then, the traveling mechanism 1 is pushed to move on the concrete. During the moving process, the film covering mechanism 3 attaches the film to the concrete surface. When the water spraying mechanism 5 sprays water on the concrete ground, it will drive the negative pressure member to move, so that a downward suction negative pressure is formed below the film covering mechanism 3, which can help the film to attach to the concrete ground. After the film is attached to the concrete ground, the film pressing mechanism 4 at the rear of the traveling mechanism 1 will extrude the film, so that the film can be more firmly attached to the surface of the concrete to cure the concrete surface. And when the wind speed is relatively high, the sides of the film can be pressed by soil and wooden sticks to prevent the wind from lifting the film. This concrete curing device integrates the traveling mechanism 1, the water tank 2, the water spraying mechanism 5, the film covering mechanism 3, the film pressing mechanism 4 and the negative pressure member, and can automatically complete a series of curing operations such as water spraying, film covering and film pressing. The film pressing mechanism 4 restricts and presses the film covering mechanism 3 to ensure that the film covering mechanism 3 is closely attached to the concrete ground and avoid gaps. The negative pressure member can adsorb the film covering mechanism 3 to one side of the concrete ground while spraying water, further enhancing the adhesion degree of the film covering mechanism 3 to the ground, effectively improving the moisture retention effect, reducing the evaporation of concrete moisture. Through the movement of the traveling mechanism 1, the device can quickly and continuously perform curing operations on the concrete road surface, greatly reducing the workload and time of manual operation and improving the curing efficiency, especially suitable for the curing work of large-area concrete road surfaces.

[0044] In an embodiment, the traveling mechanism 1 includes a top frame 11, a bottom frame 12 disposed at the lower end of the top frame 11, wheels 13 disposed on the bottom frame 12, and support wheels 14 adjustably disposed on the side of the bottom frame 12 away from the wheels 13. A handle 15 is disposed on one side of the top frame 11 close to the wheels 13.

[0045] Designed in this way, refer to Figure 1-6The handle 15 provided on the side of the top frame 11 close to the wheel 13 provides a convenient and comfortable fulcrum for the operator. The operator can easily push the entire concrete curing device to move on the road surface by holding the handle 15 without bending over or struggling to find a suitable force application position, which greatly reduces the difficulty of operation and improves the convenience and comfort of operation. It is especially suitable for long-term and large-area maintenance operations. The support wheel 14 provided on the side of the bottom frame 12 away from the wheel 13 can be adjusted, so that the walking mechanism 1 can adapt to roads of different heights and inclinations. When encountering an uneven road surface, the operator can adjust the height of the support wheel 14 according to the actual situation to ensure that the device always remains stable during the movement, avoid tilting or shaking of the device due to uneven road surface, and ensure the smooth progress of the maintenance operation.

[0046] In one embodiment, the laminating mechanism 3 includes a mounting shaft 31 detachably disposed on the top frame 11 , a mounting roller 32 sleeved on the mounting shaft 31 , and a protective film 33 disposed on the mounting roller 32 , and the protective film 33 passes through the laminating mechanism 4 .

[0047] This design, see Figure 5 The mounting shaft 31 is detachably arranged on the top frame 11. This design allows the operator to easily remove the mounting shaft 31 from the top frame 11 when the protective film 33 needs to be replaced, without the need for complicated tools and operating procedures. When laminating, the protective film 33 is passed through the film pressing mechanism 4, and then the walking mechanism 1 moves, so that the protective film 33 covers the concrete floor after the water is sprayed.

[0048] In one embodiment, the film pressing mechanism 4 includes a mounting plate 41 arranged on the side of the top frame 11 away from the handle 15, a fixing frame 42 arranged on the mounting plate 41, a supporting roller 43 arranged at the lower end of the fixing frame 42, and a limiting roller 44 adjustably arranged on the fixing frame 42 and located above the supporting roller 43 for cooperating with the supporting roller 43 to limit the protective film 33.

[0049] This design, see Figure 1-7, the protective film 33 is passed through between the support roller 43 and the limiting roller 44. The support roller 43 supports the protective film 33 from below to prevent it from sagging, while the limiting roller 44 applies a certain pressure to the protective film 33 from above to keep it flat. This coordinated up-and-down action mode can ensure that the protective film 33 will not wrinkle, loosen or shift during the laying process, ensuring the close fit of the protective film 33 to the concrete floor, improving the quality and stability of the film covering. The limiting roller 44 is adjustably arranged on the fixing frame 42. This design enables the film pressing mechanism 4 to adapt to protective films 33 of different thicknesses. In practical applications, protective films 33 of different thicknesses may be selected according to different curing requirements and conditions. By adjusting the height of the limiting roller 44, the distance between the support roller 43 and the limiting roller 44 can be ensured to be suitable for the thickness of the currently used protective film 33, thereby ensuring the limiting effect on the protective film 33 and improving the versatility and adaptability of the film pressing mechanism 4.

[0050] In one embodiment, a pressing roller 47 for pressing the protective film 33 against the concrete floor is provided on the side of the fixing frame 42 away from the top frame 11, and an adjusting member 45 for adjusting the installation position of the pressing roller 47 is provided between the pressing roller 47 and the fixing frame 42.

[0051] With this design, referring to Figure 7 , the pressing roller 47 provided on the side of the fixing frame 42 away from the top frame 11 can directly apply pressure to the protective film 33 and press it tightly against the concrete floor. By adjusting the installation position of the pressing roller 47 through the adjusting member 45, the pressure of the pressing roller 47 on the protective film 33 can be precisely controlled, ensuring the full fit of the protective film 33 to the concrete floor, effectively reducing the gap between the protective film 33 and the ground, improving the moisture retention and curing effects, and preventing problems such as the concrete cracking due to excessive water evaporation. The presence of the adjusting member 45 enables the operator to adjust the position of the pressing roller 47 according to the actual situation, so as to ensure that during the entire film pressing process, the pressure distribution of the pressing roller 47 on the protective film 33 is more uniform. Whether in the flat area or the uneven area of the road surface, by adjusting the position of the pressing roller 47, the protective film 33 can be subjected to uniform pressure, avoiding the situation of local non-compaction or excessive pressure causing damage to the protective film 33, and improving the quality and stability of the film pressing.

[0052] In one embodiment, the adjusting member 45 includes a mounting block 451 provided on the fixing frame 42, a power member 452 provided on the side of the mounting block 451 away from the top frame 11, and a connecting block 453 provided at the power output end of the power member 452. A connecting member 46 is provided between the connecting block 453 and the pressing roller 47. The power member 452 includes but is not limited to hydraulic cylinders, linear guides, electric push rods, and air cylinders.

[0053] With this design, referring to Figure 7, by controlling the telescopic length of the power component 452, the position of the connecting block 453 can be precisely adjusted, thereby achieving precise adjustment of the installation position of the pressing roller 47. This precise adjustment method can meet the fine requirements for the film pressing pressure in different curing scenarios, ensuring that the protective film 33 can be closely attached to the concrete floor in various situations, and improving the quality and effect of film pressing.

[0054] In one embodiment, the connecting member 46 includes a connecting plate 461 provided at the lower end of the connecting block 453, an outer rod 462 provided at the lower end of the connecting plate 461, an inner rod 463 sleeved inside the outer rod 462, a bottom plate 466 provided at the lower end of the inner rod 463, and a pressing plate 464 provided on the inner rod 463 and passing through the outer rod 462. An elastic member 465 is provided between the pressing plate 464 and the outer rod 462. A limiting groove 46201 for the movement of the pressing plate 464 is formed on the outer rod 462. The pressing roller 47 is connected to the bottom plate 466. The elastic member 465 is made of a damped spring or an elastic pad.

[0055] With such a design, referring to Figure 7 , when the device moves on an uneven road surface, the pressing roller 47 will receive impact forces of different degrees. The elastic member 465 changes the installation position of the pressing roller 47 through its own elastic deformation, so that the pressing roller 47 can automatically adapt to the road surface environment, enabling the protective film 33 to better adhere to the concrete floor. The pressing plate 464 is provided on the inner rod 463 and passes through the outer rod 462. The limiting groove 46201 formed on the outer rod 462 provides guiding and limiting functions for the movement of the pressing plate 464. When adjusting the height of the inner rod 463, the pressing plate 464 moves in the limiting groove 46201, ensuring the stability and precision of the adjustment process.

[0056] In one embodiment, the water spraying mechanism 5 includes a connecting pipe 51 provided on the water outlet pipe 21 at the lower end of the water tank 2, a control valve 52 provided on the connecting pipe 51, a rotating pipe 53 provided on the side of the connecting pipe 51 away from the water outlet pipe 21, a tee 55 provided on the side of the rotating pipe 53 away from the connecting pipe 51, and a water distribution pipe 56 sleeved on the tee 55. Sprayers 57 are arranged at intervals on the water distribution pipe 56. Both sides of the water distribution pipe 56 are connected to the chassis 12 through stabilizing rods 561.

[0057] With such a design, referring to Figure 6 and Figure 12-13, The water distribution pipe 56 is sleeved on the tee joint 55, and spray nozzles 57 are arranged at intervals thereon. This layout enables water to be evenly distributed to each spray nozzle 57, ensuring that during the concrete curing process, water can be evenly sprayed on the concrete floor. The control valve 52 provided on the connecting pipe 51 enables the operator to conveniently adjust the water spraying flow rate. During the actual curing process, the amount of water sprayed needs to be adjusted according to different weather conditions, types of concrete, and curing stages. The setting of the adapter pipe 53 makes the connection between the connecting pipe 51 and the tee joint 55 more flexible, and the direction and position of the water spraying mechanism 5 can be adjusted according to the actual installation space and equipment layout. When the control valve 52 is opened, the water in the water tank 2 is discharged from the water outlet pipe 21 into the connecting pipe 51, then flows into the water distribution pipe 56 along the adapter pipe 53, and then is evenly sprayed on the concrete floor from the spray nozzles 57.

[0058] In one embodiment, the negative pressure member includes a transmission member 54 arranged between the adapter pipe 53 and the tee joint 55 for transmitting kinetic energy, a steering member 58 arranged on the chassis 12 and connected to the transmission member 54, and a second fan blade 59 arranged on the chassis 12 and connected to the steering member 58. The second fan blade 59 is located below the protective film 33 for adsorbing the protective film 33 towards one side of the concrete floor.

[0059] With such a design, referring to Figure 13 , after the water flows out from the adapter pipe 53, it will pass through the transmission member 54, and then the transmission member 54 transmits the kinetic energy to the steering member 58, thereby driving the second fan blade 59 to rotate. The second fan blade 59 can generate a uniform negative pressure within a large range, enabling the protective film 33 to better adhere to the water-sprayed concrete surface, improving the adhesion efficiency between the protective film 33 and the concrete surface, and further improving the curing quality of the concrete. The second fan blade 59 is arranged below the protective film 33 and generates a negative pressure through rotation to tightly adsorb the protective film 33 on the concrete floor. This adsorption effect can effectively prevent the protective film 33 from shifting or bulging due to factors such as wind blowing and equipment movement during the curing process, ensuring that the protective film 33 always maintains a good adhesion state with the concrete floor, thereby improving the effect of moisture-preserving curing and creating a stable curing environment for the concrete.

[0060] In one embodiment, the transmission member 54 includes a connecting ring 541 sleeved on the adapter pipe 53, a water distribution block 542 arranged inside the connecting ring 541, a rotating shaft 544 arranged on the water distribution block 542 and passing through the connecting ring 541, and a first fan blade 543 sleeved on the rotating shaft 544 and located inside the connecting ring 541. A water pipe 545 communicating with the tee joint 55 is arranged on one side of the connecting ring 541 away from the adapter pipe 53, and a water outlet 54101 is opened on the side of the connecting ring 541 communicating with the water pipe 545;

[0061] The steering member 58 includes a connecting shaft 581 disposed on the rotating shaft 544, a protective box 111 disposed on the top frame 11, a driving gear 582 sleeved on the connecting shaft 581 and located inside the protective box 111, an output shaft 584 penetrating through the lower end of the protective box 111, and a driven gear 583 disposed at the upper end of the output shaft 584 and meshed with the driving gear 582. The output shaft 584 is connected to the second fan blade 59.

[0062] An installation frame 592 is disposed on the outer side of the second fan blade 59, and the upper end of the installation frame 592 is connected to the top frame 11 through a fixing rod 591.

[0063] With such a design, referring to Figure 8-11 , the first fan blade 543 is disposed inside the connecting ring 541 and sleeved on the rotating shaft 544. When water flow passes through the adapter pipe 53, it impacts the first fan blade 543 to make it rotate. This design converts part of the kinetic energy of the water flow into mechanical energy, drives the rotating shaft 544 to rotate, provides a power source for subsequent power transmission, makes full use of the energy of the water flow, reduces the use of additional power equipment, and lowers the energy consumption. The rotating shaft 544 transmits the power to the connecting shaft 581, the connecting shaft 581 transmits the power to the driving gear 582, the driving gear 582 is meshed with the driven gear 583, and the driven gear 583 drives the output shaft 584 to rotate, thereby changing the direction of power transmission, enabling the second fan blade 59 to obtain appropriate power drive, and finally driving the second fan blade 59 to rotate to generate negative pressure to adsorb the protective film 33. During the whole process, the energy of the water flow is fully utilized, the overall working efficiency of the equipment is improved, the use of additional power equipment is reduced, and the energy consumption is lowered. The driving gear 582 and the driven gear 583 are disposed inside the protective box 111, and the protective box 111 plays a role in protecting the gear set. During the operation of the equipment, the protective box 111 can prevent dust, sundries, etc. from entering the gear set, avoid gear wear and damage, and extend the service life of the gear set. An installation frame 592 is disposed on the outer side of the second fan blade 59, and the upper end of the installation frame 592 is connected to the top frame 11 through a fixing rod 591. This structural design enhances the stability of the second fan blade 59, so that it will not generate shaking or deviation during rotation, ensures the working accuracy and reliability of the second fan blade 59, and thus improves the effect of negative pressure adsorption.
