Description

Technical Field

[0001] This invention relates to the field of concrete curing technology, specifically to a concrete spray curing robot system and spray curing method. Background Technology

[0002] During the high temperatures of summer, in hot and dry conditions, failure to cure concrete in a timely manner can cause the moisture in the concrete to evaporate too quickly, leading to dehydration. This, in turn, prevents the cement particles that have already formed a gel from fully hydrating and transforming into stable crystals, resulting in insufficient bonding strength and causing flaking or powdering on the concrete surface. Therefore, spray curing is necessary. Concrete curing allows freshly poured concrete to harden normally or accelerate its strength development; it is a result of cement hydration, which requires specific temperature and humidity conditions.

[0003] The common methods of concrete spraying in existing technologies are to install pipelines on both sides of the road or to install pipelines on the boom of a tower crane. In order to increase the coverage area, the installation height is relatively high. At the same time, in order to avoid damage to the concrete surface caused by large water flow, the water is sprayed in an atomized manner. The combination of high height and atomized spraying makes it easy to be affected by the surrounding wind speed, resulting in insufficient spray curing.

[0004] A search revealed existing publications regarding spray curing devices for concrete. For example, Chinese Patent Publication No. CN212561181U discloses a spray curing device, a continuous concrete beam, and a spray curing system. This spray curing device includes a spray frame, spray heads, and water supply pipes. Multiple spray heads are present, and the water supply pipes and multiple spray heads are all installed on the spray frame, with the water inlet ends of the multiple spray heads connected to the water supply pipes. The aforementioned spray curing device is installed on the continuous concrete beam. The spray curing system includes a water pump, a distribution box, and the aforementioned spray curing device. The water supply pipes are connected to the water pump, and the power distribution device in the distribution box controls the start and stop of the water pump.

[0005] For example, Chinese Patent Publication No. CN 110480816 A discloses a spray system and method for curing reinforced concrete air-raid shelter doors. The spray system in this patent includes: a controller, two curing zones, at least two longitudinal spray tracks located between the two curing zones, a spray vehicle, and a humidity detection device. The spray vehicle includes: two wheel sets located on the longitudinal spray tracks, a chassis equipped with a driving device, two detection sensors respectively mounted on both sides of the chassis, a water tank mounted on the chassis with an inlet, a submersible pump in the water tank, a vertical water pipe connected to the outlet of the submersible pump at its lower end, a horizontal water pipe connected to the upper end of the vertical water pipe, and two spray components corresponding to the two curing zones. Each spray component includes: several spray pipes with spray heads at their lower ends and connected to the horizontal water pipes at their upper ends. The detection sensors and the submersible pump are electrically connected to the controller.

[0006] Of the two patents mentioned above, the first focuses on achieving automatic and uniform spraying to reduce the shortcomings of manual spraying, such as uneven spraying, poor curing effect, and high labor costs. The second patent focuses on using automated control to control the spraying time and ensure curing quality by controlling the curing humidity. However, neither of these technical solutions considers the necessity of atomized spraying. When the spray volume is large, it can easily damage the concrete surface. Furthermore, when using atomized spraying, the atomized water flow is inevitably affected by the surrounding wind speed, especially in high-rise curing where strong winds can cause uneven spraying and relatively poor curing effect. Therefore, there is an urgent need for a new type of concrete spraying curing robot to solve the above problems. Summary of the Invention

[0030] 3. Beneficial effects

[0031] Compared with the prior art, the beneficial effects of the present invention are:

[0032] (1) The present invention provides a concrete spray curing robot system, which includes two sets of spray guide components and a spray pipe support component installed between them. The spray pipe is mounted on the spray pipe support component for spraying. The spray pipe support component has a height adjustment function, which can adjust the distance between the spray pipe and the spray surface (i.e., the concrete surface) according to actual needs to avoid the problem of poor curing effect caused by strong winds during atomized spraying. In use, the spray pipe is adjusted to a suitable height, allowing it to be suspended low on the concrete pavement, thereby improving the accuracy and effect of spray curing. In addition, the spray guide component of the present invention is equipped with a periodic drive device, which can control the spray pipe support component to drive the spray pipe to periodically atomize and spray during spraying, further improving the spraying effect and compensating for the uneven atomized spray curing caused by strong winds.

[0033] (2) A concrete spray curing robot system of the present invention, wherein the spraying guide assembly includes a guide chain, a driven guide seat and an active guide seat, both of which are equipped with gears. The guide chain passes through the driven guide seat and the active guide seat and meshes with the gears. The active guide seat is connected to a drive device. The drive device drives the gears on the active guide seat to rotate. By utilizing the meshing of the guide chain, all gears are driven to rotate. The meshing chain is used for transmission, thereby driving the spray pipe support assembly installed on the spraying guide assembly to move, so as to achieve uniform reciprocating spraying of the spray pipe.

[0034] (3) A concrete spraying curing robot system of the present invention includes multiple spray pipe support components for supporting the spray pipes to perform spraying curing on the concrete surface. During curing, multiple spray pipes spray atomized water simultaneously, which can significantly improve the efficiency of spraying work, quickly achieve concrete curing, and significantly improve the curing effect of concrete. More optimized, the spray pipe support component includes a clamping head and a telescopic adjustment support frame. The clamping head is used to clamp the entire spray pipe support component on the spraying guide component, playing a supporting and driving role. The telescopic adjustment support frame can adjust the length and erection height of the spray pipe support component to adapt to concrete pavements of different widths and reduce the influence of wind speed on atomized spraying, so as to achieve excellent spraying effect.

[0035] (4) A concrete spraying curing robot system of the present invention, wherein the positioning plate is fixedly installed on the support plate and the positioning plate is provided with positioning nails. The positioning plate is used to accurately position the driven guide seat and the active guide seat, which can meet the requirements of the spraying guide component for various sloping concrete pavements.

[0036] (5) A concrete spraying and curing robot system of the present invention, wherein the telescopic adjustment support frame is provided with multiple telescopic adjustment rods with the same structure, and each pair of telescopic adjustment rods is connected by a spray pipe support platform. The spray pipe support platform uses the groove opened on its top to limit and support the spray pipe. By setting multiple telescopic adjustment rods and spray pipe support platforms, the supporting force of the spray pipe can be distributed evenly to carry out spraying and curing, so as to adapt to various road surfaces, avoid the problem of increasing the workload by laying pipelines over a large area and the problem of road surface depression caused by traditional spraying machinery walking on the road surface.

[0037] (6) A concrete spraying and curing robot system of the present invention, wherein the telescopic adjustment support frame is provided with a height adjustment rod, the height adjustment rod has the same structure as the telescopic adjustment rod, and by adjusting the length of the extension of the height adjustment rod, the height of the spray pipe support assembly supporting the spray pipe can be adjusted to adapt to the actual concrete ground. After adjusting the height of multiple spray pipe support assemblies in a local area, multiple spray pipes are formed at appropriate heights to suit some concrete grounds with stepped, grooved or other shapes for spraying and curing, and the system has wide applicability.

[0038] (7) The concrete spray curing method of the present invention uses the spray curing robot system of the present invention for curing, which can effectively avoid the influence of wind speed on atomized spraying. At the same time, it is applicable to various specifications and terrains, such as the curing of sloping concrete pavements with different slopes. In addition, the curing method of the present invention uses spray pipes erected at a low altitude above the concrete pavement for spray curing, which can adapt to various pavements and avoid the problem of increasing workload due to large-scale pipeline laying and the problem of pavement depression caused by traditional spraying machinery walking on the road surface.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0061] Furthermore, it should be understood that, for ease of description, the dimensions of the various components shown in the accompanying drawings are not drawn to actual scale; for example, the thickness or width of some layers may be exaggerated relative to other layers.

[0062] Example 1

[0063] like Figure 1 and Figure 2 As shown, this embodiment of a concrete spray curing robot system includes a curing robot body 1, a spraying guide assembly 4, a spraying pipe support assembly 5, and a spraying pipe 6. The curing robot body 1 is equipped with a storage box, inside which is a storage roller for storing the spraying guide assembly 4. The storage box is mounted on a mounting plate 11 and then mounted on a base 12 via the mounting plate 11. A water supply pipe 13 is inserted through the base 12 for connecting to an external water source.

[0064] The storage box has two discharge ports 3 installed at its front end, each corresponding to one of the two spray guide components 4. A storage door 2 is also provided on the front surface of the storage box. The spray pipe support component 5 and the spray pipe 6 can be stored inside the storage box behind the storage door 2. The spray pipe 6 is externally connected to the base 12 for connecting to a water suction pipe 13. This water suction pipe 13 connects to an external water source to achieve spray curing of the concrete surface. It should be noted that an atomizing nozzle 61 is installed at the bottom of the spray pipe 6. The structure of the spray pipe 6 and the atomizing nozzle 61 is existing technology and can be directly purchased commercially. The material and length of the spray pipe 6 can be adjusted according to actual application requirements and will not be described in detail here. The placement of the atomizing nozzle 61 needs to be determined based on the specific spraying requirements of this invention.

[0065] Two spray guide components 4 are provided. In use, the two spray guide components 4 are respectively erected on both sides of the concrete to be cured. At least one spray pipe support component 5 is installed between the two spray guide components 4, and the spray pipe support component 5 is set perpendicular to the length direction of the spray guide components 4. The spray pipe 6 is installed on the spray pipe support component 5. The spray pipe support component 5 is used to support and install the spray pipe 6. At the same time, the spray pipe support component 5 also has a height adjustment function, which makes it easy to adjust the distance between the spray pipe 6 and the spray surface according to actual needs, so as to avoid the problem that the atomized spraying is easily affected by strong winds, resulting in poor curing effect. At present, the spraying devices sold on the market, especially the atomized spraying devices, are easily affected by the surrounding wind speed during use, resulting in uneven atomized spraying and a significant reduction in the curing effect of concrete; at the same time, some spraying devices inevitably damage the concrete surface during operation. Therefore, in the spraying maintenance robot system provided by the present invention, on the one hand, by setting up a spraying guide component 4 and a spraying pipe support component 5, the height of the spraying pipe 6 can be easily adjusted so that it can be suspended low on the concrete road surface during operation, thereby improving the accuracy and effect of spraying maintenance.

[0066] On the other hand, the present invention has a driving device installed on the spray guide assembly 4, which is used to drive the spray pipe support assembly 5 to move during use. During spraying, the spray pipe support assembly 5 can be controlled to drive the spray pipe 6 to periodically atomize and spray, which further improves the spraying effect and makes up for the phenomenon of uneven atomization spraying maintenance caused by strong winds.

[0067] Example 2

[0068] This embodiment of the concrete spraying curing robot system has a basically the same main structure as that of Embodiment 1. The main difference between the two embodiments is as follows: Figure 1 and Figure 3-5As shown, two spray guide components 4 are housed inside the main body 1 of the maintenance robot. The two spray guide components 4 are used to support the spray pipe support components 5 from both sides and drive the spray pipe support components 5 and the spray pipe 6 to move back and forth periodically to increase the range for spraying and curing the concrete surface.

[0069] Specifically, such as Figure 4 As shown, each spray guide assembly 4 includes a guide chain 41, a driven guide seat 42, and an active guide seat 43. The active guide seat 43 and the driven guide seat 42 have basically the same structure. Both the active guide seat 43 and the driven guide seat 42 are provided with a support plate 422. The support plate 422 is machined with a groove 424. A gear 421 is rotatably installed in each groove 424 through a rotating shaft 423. The guide chain 41 is installed in the middle of the groove 424 of the support plate 422 and meshes with the gear 421 installed in the groove 424. The difference between the active guide seat 43 and the driven guide seat 42 is that one end of the rotating shaft 423 for mounting the gear 421 on the active guide seat 43 is connected to a drive device. The drive device drives the gear 421 on the active guide seat 43 to rotate, which in turn meshes with the guide chain 41 to drive the gear 421 on the driven guide seat 42 to rotate, thereby moving the spray pipe support assembly 5 installed on the spray guide assembly 4.

[0070] As an improvement to this embodiment, each spray guide assembly 4 is provided with multiple active guide seats 43 and multiple driven guide seats 42. The number of active guide seats 43 and driven guide seats 42 is the same, and the active guide seats 43 and driven guide seats 42 are arranged in a cross array to jointly support the guide chain 41, thereby improving the support stability of the spray pipe support assembly 5. At least one active guide seat 43 is connected to a drive device to provide the driving force for the movement of the spray pipe support assembly 5.

[0071] Furthermore, to ensure the smooth and stable reciprocating movement of the spray pipe support assembly 5, achieving periodic reciprocating spraying, providing an atomized spraying effect, and reducing the impact of wind speed on the spraying effect, multiple drive devices are also installed. Each active guide seat 43 is individually connected to a drive device. These drive devices are periodic drive devices. During use, activating the periodic drive device drives the gear 421 on the active guide seat 43, causing the guide chain 41 to move periodically back and forth. In addition, the spray pipe support assembly 5 is vertically mounted on the guide chain 41, preventing the guide chain 41 from tipping over during movement. Instead, the guide chain 41 and gear 421 mesh more tightly, providing driving force and stable support for the movement of the spray pipe support assembly 5.

[0072] In addition, such as Figure 4 and Figure 5As shown, the spraying maintenance robot system of the present invention also includes a positioning plate 426, which is fixedly installed on the support plate 422. The positioning plate 426 is provided with positioning pins 425. The positioning plate 426 is used to accurately position the driven guide seat 42 and the active guide seat 43, ensuring that the spraying guide assembly 4 is suitable for various sloping concrete pavements. Furthermore, the driving device described in this invention uses a motor 431, which is fixedly installed on the outside of the support plate 422 via a sliding plate 432.

[0073] As another improvement to this embodiment, such as Figure 1 and Figure 12 As shown, the spray pipe support assembly 5 in this embodiment is provided in multiple parts to support the spray pipes 6 for spray curing on the concrete surface. During the curing work, multiple spray pipes 6 spray atomized water together, which can significantly improve the efficiency of spraying, quickly achieve the curing of concrete, and significantly improve the curing effect of concrete.

[0074] Example 3

[0075] This embodiment of the concrete spraying curing robot system has a basically the same main structure as that of Embodiment 2. The main difference between the two embodiments is as follows: Figure 6 As shown, the spray pipe support assembly 5 includes a clamping head 53 and a telescopic adjustment support frame. The telescopic adjustment support frame includes a telescopic adjustment rod 51 and a height adjustment rod 52. Both ends of the telescopic adjustment rod 51 are connected to the clamping head 53 via the height adjustment rod 52. The clamping head 53 clamps the spray pipe support assembly 5 onto the spray guide assembly 4 to achieve installation. The telescopic adjustment rod 51 is used to adjust the length of the telescopic adjustment support frame. The length of the spray pipe support assembly 5 is adjusted by utilizing the length of the telescopic adjustment rod 51 itself and its telescopic adjustment to adapt to concrete pavements of different widths. The height adjustment rod 52 is used to adjust the erection height of the telescopic adjustment support frame. On one hand, it controls the distance between the spray pipe 6 and the concrete surface. Considering the wind speed at the construction site and the concrete curing requirements, the erection height of the spray pipe 6 is adjusted to achieve excellent atomized spraying effects and minimize the impact of wind speed on the atomized spraying effect.

[0076] In addition, such as Figure 10 and Figure 11 As shown, a row of multiple arrayed atomizing nozzles 61 are respectively opened on both sides of the spray pipe 6 to further improve the atomizing spraying effect.

[0077] like Figure 6 , Figure 7 and Figure 8As shown, as another improvement in this embodiment, the telescopic adjustment support frame is provided with multiple telescopic adjustment rods 51 with identical structures. The structure of the telescopic adjustment rods 51 is the same as that of the height adjustment rods 52. Each pair of telescopic adjustment rods 51 is connected by a spray pipe support platform 514, and the telescopic adjustment rods 51 and the height adjustment rods 52 are connected by a spray pipe support platform 514. A spray pipe 6 is installed on the top of the spray pipe support platform 514, and the spray pipe support platform 514 uses a groove on its top to limit and support the spray pipe 6. Due to the arrangement of multiple telescopic adjustment rods 51 and multiple spray pipe support platforms 514, the supporting force of the spray pipe 6 can be distributed and evenly distributed. The multiple telescopic adjustment rods 51 can adjust the length of the telescopic adjustment support frame and the spray pipe support assembly 5 by adjusting their own length.

[0078] Through the above design, the spray pipe 6 can be suspended low above the concrete road surface, avoiding the influence of surrounding wind speed after atomization spraying, thus improving the accuracy and effect of atomization spraying maintenance. Simultaneously, the arbitrary placement of the two spray guide components 4, combined with the multiple telescopic adjustment rods 51, allows for length adjustment of the telescopic support frame and spray pipe support components 5 to adapt to concrete road surfaces of varying widths. Multiple spray pipe support platforms 514 distribute the supporting force evenly, supporting the spray pipe 6 for spraying maintenance, adapting to various road surfaces and avoiding the increased workload of large-scale pipeline installation and the road surface depressions caused by traditional spraying machinery moving on the road. Furthermore, this invention, by setting multiple spray pipe support components 5, can support multiple spray pipes 6, and combined with the drive of the spray guide components 4, achieves periodic back-and-forth movement, increasing the coverage area for high-coverage spraying maintenance of the concrete surface.

[0079] Example 4

[0080] This embodiment of the concrete spraying curing robot system has a basically the same main structure as that of Embodiment 3. The main difference between the two embodiments is as follows: Figure 7 As shown, the telescopic adjustment rod 51 includes a storage tube A511, a threaded tube A512, and a threaded rod A513. The threaded rod A513 is movably installed inside the storage tube A511 through the threaded tube A512.

[0081] Specifically, a threaded tube A512 is rotatably connected to the receiving tube A511, and a threaded rod A513 is threaded through the threaded tube A512; one end of the threaded rod A513 extends out of the threaded tube A512 and enters the receiving tube A511. When the threaded tube A512 is rotated, the threaded rod A513 extends out or retracts into the receiving tube A511 under the action of the thread, realizing the length adjustment of the telescopic adjustment rod 51.

[0082] Meanwhile, a detachable limit buckle A is provided on the threaded tube A512, which, after assembly, limits the rotation of the threaded tube A512. When the limit buckle A is released, the threaded tube A512 engages with the threaded rod A513 through threaded transmission, thereby adjusting the length of the threaded rod A513 inserted inside the receiving tube A511, and thus adjusting the length of the telescopic adjustment rod 51. This allows for adjustment of the length of the telescopic adjustment support frame and the spray pipe support assembly 5, adapting to concrete pavements of different widths.

[0083] like Figure 8 As shown, the height adjustment rod 52 includes a receiving tube B523, a threaded tube B524, and a threaded rod B521. The threaded rod B521 is movably installed inside the receiving tube B523 through the threaded tube B524. One end of the receiving tube B523 is rotatably installed on the clamping head 53 through a bearing seat 522.

[0084] Specifically, a threaded tube B524 is rotatably connected to the receiving tube B523, and a threaded rod B521 is threaded through the threaded tube B524. One end of the threaded rod B521 passes through the threaded tube B524 and enters the interior of the receiving tube B523. The threaded rod B521 is fixed below the spray pipe support platform 514. The receiving tube B523 is rotatably connected to the clamping plate 531 through the bearing seat 522.

[0085] The threaded pipe B 524 is detachably equipped with a limit buckle B, which, after assembly, limits the rotation of the threaded pipe B 524. After removing the limit buckle B, the threaded pipe B 524 engages with the threaded rod B 521, allowing adjustment of the length of the threaded rod B 521 inserted inside the receiving pipe B 523. This adjusts the height of the height adjustment rod 52, thereby adjusting the height of the spray pipe support assembly 5 supporting the spray pipe 6 to adapt to the actual concrete surface. By adjusting the height of multiple spray pipe support assemblies 5 at different locations, multiple spray pipes 6 are formed at suitable heights to accommodate the spray curing of concrete surfaces with stepped, recessed, or other similar shapes, making it widely applicable.

[0086] Example 5

[0087] This embodiment of a concrete spraying curing robot system has a basically the same main structure as that of Embodiment 4, but the main difference between the two embodiments is as follows: Figure 6 , Figure 7 and Figure 9 As shown, the spray pipe support assembly 5 includes two clamping heads 53, which are used to clamp onto the spray guide assembly 4, wherein:

[0088] The clamping head 53 is provided with a clamping plate 531, which is L-shaped. A movable plate 533 is slidably connected to the clamping plate 531. A locking member 534 is provided between the movable plate 533 and the clamping plate 531. The locking member 534 is used to adjust the distance between the movable plate 533 and the clamping plate 531 and clamps them on the spray guide assembly 4.

[0089] In use, the spray pipe support assembly 5 uses the locking element 534 on the clamping head 53 to adjust the distance between the moving upright plate 533 and the clamping upright plate 531, and clamps it on the spray guide assembly 4.

[0090] Furthermore, as another improvement to this embodiment, such as Figure 9 As shown, the locking member 534 is also equipped with a lead screw, which is threaded through the movable upright plate 533. The end of the lead screw is rotatably mounted on the clamping upright plate 531. The locking member 534 also includes a telescopic sleeve, of which two are provided and distributed between the movable upright plate 533 and the clamping upright plate 531 on both sides of the lead screw. Multiple rotating rollers 532 are rotatably connected to the opposing surfaces of the movable upright plate 533 and the clamping upright plate 531. When the clamping head 53 is clamped on the spray guide assembly 4, the lead screw is rotated to achieve threaded engagement between the lead screw and the movable upright plate 533, driving the movable upright plate 533 closer to the clamping upright plate 531. The movable upright plate 533 and the protruding edge on the clamping upright plate 531 on the upper side of the rotating rollers 532 are clamped on the spray guide assembly 4. The arrangement of multiple rotating rollers 532 facilitates the periodic back-and-forth movement of the spray pipe support assembly 5 on the spray guide assembly 4, increasing the range for high-coverage spray curing of the concrete surface.

[0091] Example 6

[0092] This embodiment provides a concrete spray curing method, which uses the concrete spray curing robot system provided by this invention to perform concrete curing, and specifically includes the following steps:

[0093] Step 1: Adjust the spacing between the two spray guide components 4 according to the width of the concrete to be cured, and set up the two spray guide components 4 on both sides of the concrete to be cured.

[0094] Step 2: Based on the actual curing process conditions of the concrete pavement, install an appropriate number of spray pipe support components 5 on the two spray guide components 4; adjust the length of multiple telescopic adjustment rods 51 according to the width of the concrete pavement to match the pavement width and achieve spraying.

[0095] Step 3: Adjust the installation height of the spray pipe support assembly 5 so that the spray pipe 6 is low above the concrete surface for atomized spraying. Specifically, place the spray pipe 6 on the spray pipe support assembly 5, with both ends of the spray pipe support assembly 5 supported by two spray guide assemblies 4, so that the spray pipe 6 is low above the concrete pavement. This avoids the situation where the atomized spraying is easily affected by the surrounding wind speed, thereby improving the accuracy and effect of spray curing.

[0096] Step 4: When the concrete surface to be cured is not horizontal, adjust the height of the spray pipe support assembly 5 erected above the concrete surface to ensure that the corresponding spray pipe support assembly 5 is low to the ground above the concrete surface. Specifically, after removing the limiting buckle B, the threaded pipe B 524 and the threaded rod B 521 engage in threaded transmission, allowing adjustment of the length of the threaded rod B 521 inserted inside the receiving pipe B 523. This adjusts the height of the height adjustment rod 52, thereby adjusting the height of the spray pipe support assembly 5 supporting the spray pipe 6 to adapt to the actual concrete surface. By adjusting the height of multiple spray pipe support assemblies 5 in different areas, multiple spray pipes 6 are formed at appropriate heights to suit the spray curing of concrete surfaces with stepped, grooved, or other shapes. Furthermore, for the curing of sloping concrete pavements with a certain gradient, the positioning pins 425 can be used for fixation, significantly improving the operational stability of the curing robot system and making it more suitable for the curing of various sloping concrete pavements.

[0097] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
