Description

Technical Field

[0001] This application relates to the field of concrete spray curing, and in particular to a concrete spray curing system and its usage method. Background Technology

[0002] Concrete is one of the most important civil engineering materials in modern times. It is an artificial stone material made by mixing cementitious materials, granular aggregates (also known as aggregates), water, and, if necessary, admixtures and additives in a certain proportion, uniformly stirring, compacting, and curing.

[0003] During the hardening process of concrete, in order to ensure the strength of the concrete and prevent cracks from forming due to surface drying, it is necessary to water the concrete for curing.

[0004] Currently, spray curing of concrete pavements generally requires laying long water pipes along the concrete pavement or using a tower crane to hoist the water pipes into the air to spray the concrete pavement; while spray curing of concrete columns requires installing trusses on the concrete columns and laying ring-shaped water pipes on the trusses, and then moving the water pipes downwards from the top to spray the concrete columns.

[0005] However, both of the above situations need to be judged based on the actual construction conditions. If it is a concrete pavement, water pipes need to be temporarily laid along the length of the concrete pavement; if it is a concrete column, trusses and ring-shaped water pipes need to be temporarily erected. Both need to be temporarily erected, cannot be used interchangeably, resulting in low applicability. Moreover, the erection process is not only time-consuming, but also cumbersome. Summary of the Invention

[0006] To address the issues of low applicability due to the incompatibility of the aforementioned spraying systems, and the time-consuming and cumbersome construction process, this application provides a concrete spraying curing system and its usage method.

[0007] In the first aspect, this application provides a concrete spray curing system, which adopts the following technical solution:

[0008] A concrete spray curing system includes: an empty box, a water supply pipe on the top of the empty box, and the water supply pipe is composed of four rigid pipes coaxially connected end to end in sequence. Each rigid pipe is equipped with multiple spray nozzles. One rigid pipe located at the end of the water supply pipe is detachably fixed to the empty box. A connecting mechanism is provided between two adjacent rigid pipes.

[0009] Each connecting mechanism includes a connecting assembly, which includes two threaded cylinders, two screws, and a connecting plate. The two threaded cylinders are perpendicular to the ends of two adjacent rigid pipes that are close to each other. The screws are threadedly connected to the threaded cylinders. The connecting plate is located between two adjacent rigid pipes and its two ends are rotatably mounted to the ends of the two screws.

[0010] By adopting the above technical solution, the four rigid pipes are rotated according to the concrete pattern to adjust their state, thereby enabling spraying of concrete pavement or concrete columns. This concrete spraying curing system can be switched according to the pattern of the concrete to be sprayed and cured, unlike existing technologies that require the construction of water pipes according to the concrete pattern before spraying and curing, a process that is not only time-consuming but also cumbersome. Therefore, this concrete spraying curing system has better applicability.

[0011] Optionally, each connection mechanism includes two sets of connection components, and the two sets of connection components are arranged symmetrically about the axial direction of the rigid tube.

[0012] By adopting the above technical solution, two sets of connecting components are used to connect two adjacent rigid pipes, which can improve the stability of the connection between the two adjacent rigid pipes, as well as the stability when they rotate relative to each other.

[0013] Optionally, each connection mechanism further includes a communication component, the communication component comprising a second flexible tube detachably connected between two adjacent rigid tubes.

[0014] By adopting the above technical solution, the second flexible hose can easily connect the four rigid pipes, so that water does not need to be passed through each rigid pipe separately, and the four rigid pipes can still maintain mutual connection when they rotate relative to each other.

[0015] Optionally, it also includes: an adjustment mechanism, the adjustment mechanism comprising: an adjustment assembly, the adjustment assembly comprising: a shell, a take-up rod, a take-up rope, a limiting ear, and a take-up / discharge motor, the shell being fixed to a rigid tube near the shell, the take-up rod being rotatably mounted inside the shell, the take-up / discharge motor being fixed inside the shell for driving the take-up rod to rotate, the limiting ear being fixed to two rigid tubes located at the ends, one end of the take-up rope being fixed to the shell, and the other end passing through the limiting ear and into the shell and wound around the take-up rod.

[0016] By adopting the above technical solution, if it is necessary to spray and cure the concrete column, the retractor is started to drive the retractor to rotate. The retractor can wind up one end of the retractor rope after it is wrapped around the four rigid tubes, thereby pulling the three rigid tubes fixed in the empty box to rotate until they are perpendicular to each other, thus completing the winding. At this time, the four rigid tubes are switched to form a square loop.

[0017] Optionally, the adjustment mechanism further includes a limiting component, which includes a limiting plate, the bottom end of which is fixed to the connecting plate, and the height of the limiting plate is greater than the minimum distance between the rigid tube and the connecting plate.

[0018] By adopting the above technical solution, the limiting plate can limit the three rigid tubes that are not fixed to the empty box when the four rigid tubes rotate to be perpendicular to each other, so that the three rigid tubes that are not fixed to the empty box will stop rotating.

[0019] Optionally, the empty box is provided with a suspension mechanism for suspending the water supply pipe. The suspension mechanism includes a suspension assembly, which includes a vertical rod, a tray, a suspension rope, a hook, and a hanging ring. The vertical rod is rotatably installed inside the empty box. The tray is fixedly sleeved on the vertical rod. One end of the suspension rope is wrapped around the vertical rod, and the other end passes through the empty box and is fixed to the hook. The hanging ring is fixed to the rigid pipe.

[0020] By adopting the above technical solution, the hook is hung on the hanging ring, and then the suspension rope is loosened to lower the water supply pipe.

[0021] Optionally, the suspension mechanism further includes a transmission assembly, which includes a drive gear, a driven gear, and a drive motor. The drive motor is fixed inside the empty box and its output end is coaxially fixed with the drive gear. The driven gear is coaxially sleeved on the vertical rod and meshes with the drive gear.

[0022] By adopting the above technical solution, the drive motor is started to drive the active gear to rotate the driven gear, thereby driving the vertical rod to loosen the suspension rope; after loosening to a certain extent, the drive motor is stopped, and the rigid pipe fixed to the empty box is separated from the empty box. Then, the hook is hung on the corresponding hanging ring, and the water supply pipe is sleeved on the concrete column. Finally, the drive motor is started again to loosen the suspension rope, so that the water supply pipe moves downward in the vertical direction to spray and cure the concrete column.

[0023] Optionally, it also includes a swing mechanism disposed between the rigid tube and the nozzle, wherein the nozzle and the rigid tube are connected by a first flexible tube, and the swing mechanism includes a swing assembly, wherein the swing assembly includes a push plate and a connecting rod, the push plate is fixed to the nozzle, one end of the connecting rod is hinged to the push plate and the other end is connected to the rigid tube.

[0024] By adopting the above technical solution, the driving connecting rod drives the push plate to move, thereby pushing the nozzle to swing and increasing the spray area.

[0025] Optionally, the oscillating mechanism further includes a oscillating drive assembly, which includes a receiving plate, blades, a worm, a worm wheel, and a guide plate. The receiving plate is fixed to the rigid pipe, and the worm wheel is rotatably mounted on the receiving plate. The guide plate is fixed inside the rigid pipe. One end of the worm is rotatably mounted inside the rigid pipe and fixed to the blades, while the other end passes through the rigid pipe and meshes with the worm wheel. The end of the connecting rod away from the push plate is rotatably mounted on the worm wheel.

[0026] By adopting the above technical solution, when the water flows through the gap between the guide plate and the inner wall of the rigid pipe, it will strike the blades, thereby causing the worm to rotate. The rotation of the worm will drive the worm wheel to rotate, and through the connecting rod, it will push the push plate to reciprocate. The push plate will drive the nozzle to swing, thereby increasing the spraying area of ​​the concrete pavement and better spraying concrete columns. Moreover, there is no need to use an electric structure to drive the nozzle to swing; simply supplying water is enough to immediately realize the swing of the nozzle.

[0027] Secondly, this application provides a method for using a concrete spray curing system, employing the following technical solution:

[0028] A method for using a concrete spray curing system includes the following steps:

[0029] S1: Adjust the water supply pipe status by operating the adjustment mechanism according to the concrete pattern;

[0030] S2: If spraying concrete pavement, water is directly supplied into the water supply pipe; if spraying concrete columns, a suspension mechanism is required to suspend the water supply pipe below.

[0031] S3: After water is supplied, the spray nozzle will automatically swing through the swing mechanism to spray and cure the concrete.

[0032] By adopting the above technical solutions, the applicability of the concrete spraying curing system can be improved.

[0033] In summary, this application includes at least one of the following beneficial effects:

[0034] 1. This concrete spray curing system can be adapted to the different types of concrete to be sprayed and cured. Unlike existing technologies, which require the installation of water pipes based on the concrete type before spray curing, and which is time-consuming and cumbersome, this concrete spray curing system has better applicability.

[0035] 2. The second flexible hose facilitates the connection of the four rigid pipes, thus eliminating the need to individually circulate water through each rigid pipe, and the four rigid pipes can still maintain interconnection when they rotate relative to each other.

[0036] 3. Hang the hook on the hanging ring, and then loosen the suspension rope to lower the water supply pipe. Attached Figure Description

[0043] This application provides a concrete spray curing system.

[0044] See Figure 1 A concrete spray curing system generally includes: an empty box 1, all surfaces of which are enclosed. Wheels 12 are rotatably mounted on the empty box 1 via a pivot 11, and the pivot 11 extends through the interior of the empty box 1. The wheels 12 facilitate the movement of the empty box 1 on the road surface, eliminating the need to carry the empty box 1 and thus saving physical effort.

[0045] See Figure 2 and Figure 3 The empty box 1 is equipped with a drive assembly 13, which includes a first gear 131, a second gear 132, and a drive motor 133. The drive motor 133 is installed inside the empty box 1, and its output end is coaxially fixed with the first gear 131. The second gear 132 is coaxially fixedly sleeved on the rotating shaft 11 and meshes with the first gear 131. When the empty box 1 needs to be moved, the drive motor 133 is started to drive the first gear 131 to rotate. The rotation of the first gear 131 can sequentially drive the second gear 132 and the rotating shaft 11 to rotate, thereby driving the wheel 12 to move the empty box 1, thus improving the ease of moving the empty box 1.

[0046] See Figure 1The top of the empty box 1 is equipped with a water supply pipe 3, which consists of four rigid pipes (first rigid pipe 31, second rigid pipe 32, third rigid pipe 33, and fourth rigid pipe 34) connected end to end in sequence. Initially, the first rigid pipe 31, second rigid pipe 32, third rigid pipe 33, and fourth rigid pipe 34 are coaxial. Connecting mechanisms are provided between the first rigid pipe 31 and the second rigid pipe 32, between the second rigid pipe 32 and the third rigid pipe 33, and between the third rigid pipe 33 and the fourth rigid pipe 34. The first rigid pipe 31 is detachably fixed to the top of the empty box 1 by clamps and bolts, and a connector for an external water source is provided on the first rigid pipe 31. Furthermore, in this embodiment, a counterweight can be fixed inside the empty box 1 to increase its weight, making it less prone to tilting.

[0047] See Figure 4 The bottoms of the first rigid pipe 31, the second rigid pipe 32, the third rigid pipe 33 and the fourth rigid pipe 34 are all connected to a spray pipe 36 with a built-in nozzle through the first flexible hose 35. When it is necessary to spray and cure the concrete pavement, water can be introduced into the water supply pipe 3, and then the water will be sprayed out through the spray pipe 36 to spray and cure the concrete pavement.

[0048] See Figure 4 The connecting mechanism includes: connecting component 4 and connecting component 5.

[0049] See Figure 4 In this embodiment, the connecting components 4 between the first rigid pipe 31 and the second rigid pipe 32, between the second rigid pipe 32 and the third rigid pipe 33, and between the third rigid pipe 33 and the fourth rigid pipe 34 are configured in two groups, and are symmetrically arranged with the axes of the first rigid pipe 31, the second rigid pipe 32, the third rigid pipe 33 and the fourth rigid pipe 34 as the central axis, thereby improving the connection stability between the first rigid pipe 31 and the second rigid pipe 32, between the second rigid pipe 32 and the third rigid pipe 33, and between the third rigid pipe 33 and the fourth rigid pipe 34.

[0050] The connecting assembly 4 includes two screws 41, two threaded cylinders 42, and a connecting plate 43. The two threaded cylinders 42 are perpendicular to the ends of two adjacent rigid pipes (31, 32, 33, 34) that are close to each other. The screws 41 are threaded into the threaded cylinders 42. The connecting plate 43 is located between two adjacent rigid pipes (31, 32, 33, 34) and its two ends are rotatably installed with the ends of the two screws 41 respectively.

[0051] During installation, the screw 41 can be screwed into the corresponding threaded cylinder 42, thereby connecting the four rigid pipes (31, 32, 33, 34), and the first rigid pipe 31, the second rigid pipe 32, the third rigid pipe 33, and the fourth rigid pipe 34 can rotate relative to each other. If the concrete spraying curing is not required for a long time, the screw 41 can be unscrewed from the threaded cylinder 42, thereby separating the first rigid pipe 31, the second rigid pipe 32, the third rigid pipe 33, and the fourth rigid pipe 34 from each other, reducing the space occupied and making it easier to store.

[0052] See Figure 4 The connecting component 5 includes a second flexible hose 51, which is detachably connected between the first rigid pipe 31 and the second rigid pipe 32, between the second rigid pipe 32 and the third rigid pipe 33, and between the third rigid pipe 33 and the fourth rigid pipe 34 via flanges and bolts. The second flexible hose 51 facilitates the connection between the first rigid pipe 31, the second rigid pipe 32, the third rigid pipe 33, and the fourth rigid pipe 34, thereby eliminating the need to individually circulate water through each of the first rigid pipe 31, the second rigid pipe 32, the third rigid pipe 33, and the fourth rigid pipe 34, and can maintain the interconnection between them even when they rotate relative to each other.

[0053] See Figure 1 , Figure 3 and Figure 4 An adjustment mechanism is provided between the first rigid tube 31 and the fourth rigid tube 34. The adjustment mechanism includes an adjustment component 6 and a limit component 7.

[0054] See Figure 1 and Figure 3 The adjustment assembly 6 includes: a housing 61, a take-up / release rod 62, a take-up / release rope 63, a limiting ear 64, and a take-up / release motor 65. The housing 61 is fixed to the end of the first rigid tube 31 away from the second rigid tube 32. The take-up / release rod 62 is rotatably installed inside the housing 61, and the take-up / release rod 62 is horizontally positioned with its axis perpendicular to the axis of the first rigid tube 31. The take-up / release motor 65 is fixedly installed inside the housing 61, and its output end is coaxially fixed with the take-up / release rod 62.

[0055] The limiting ear 64 is fixed to the end of the first rigid tube 31 away from the second rigid tube 32 and to the end of the fourth rigid tube 34 away from the third rigid tube 33. One end of the take-up rope 63 is fixed to the side wall of the empty shell 61, and the other end passes through the limiting ear 64 and through the empty shell 61 and is wrapped around the take-up rod 62. The take-up rope 63 surrounds the first rigid tube 31, the second rigid tube 32, the third rigid tube 33 and the fourth rigid tube 34.

[0056] See Figure 4The limiting component 7 includes a limiting plate 71, which is fixed to the connecting plate 45. The limiting plate 71 can limit the second hard pipe 32, the third hard pipe 33 and the fourth hard pipe 34 when the fourth hard pipe 34 rotates to be perpendicular to the third hard pipe 33, the third hard pipe 33 rotates to be perpendicular to the second hard pipe 32 and the second hard pipe 32 rotates to be perpendicular to the first hard pipe 31, so that the second hard pipe 32, the third hard pipe 33 and the fourth hard pipe 34 no longer continue to rotate.

[0057] If spray curing is required on concrete columns, such as bridge piers, the retractor 65 is started to drive the retractor 62 to rotate. The retractor 62 can wind up one end of the retractor rope 63 after it has wrapped around the first rigid pipe 31, the second rigid pipe 32, the third rigid pipe 33, and the fourth rigid pipe 34, thereby pulling the second rigid pipe 32, the third rigid pipe 33, and the fourth rigid pipe 34 to rotate until they abut against the limiting plate 71, thus completing the winding. At this time, the first rigid pipe 31, the second rigid pipe 32, the third rigid pipe 33, and the fourth rigid pipe 34 change to form a square loop.

[0058] In this embodiment, a torsion spring is fitted on the threaded cylinder 42, and grooves are provided on the connecting plate 43 and the water supply pipe 3. The two ends of the torsion spring abut against the corresponding grooves, so that the first hard pipe 31, the second hard pipe 32, the third hard pipe 33 and the fourth hard pipe 34 can automatically return to the coaxial state.

[0059] See Figure 3 The empty box 1 is equipped with a suspension mechanism to suspend the water supply pipe 3. The suspension mechanism includes a suspension assembly 8 and a transmission assembly 9. In this embodiment, the suspension assembly 8 is configured in four groups, and the four groups of suspension assemblies 8 correspond one-to-one with the first rigid pipe 31, the second rigid pipe 32, the third rigid pipe 33 and the fourth rigid pipe 34, thereby ensuring the stability of the water supply pipe 3 when it is suspended.

[0060] See Figure 3 and Figure 4 The suspension assembly 8 includes: vertical rods 81, a tray 82, a suspension rope 83, hooks 84, and hanging rings 85. The vertical rods 81 are rotatably installed inside the empty box 1. The four vertical rods 81 are arranged in a circle and vertically, corresponding one-to-one with the four side walls of the empty box 1. The tray 82 is fixedly fitted onto the vertical rods 81. One end of the suspension rope 83 is wrapped around the vertical rods 81 and positioned above the tray 82; the other end passes through the empty box 1 and is fixed to the hooks 84. The hanging rings 85 are fixed to the first rigid pipe 31, the second rigid pipe 32, the third rigid pipe 33, and the fourth rigid pipe 34. When the first rigid pipe 31, the second rigid pipe 32, the third rigid pipe 33, and the fourth rigid pipe 34 are transformed into a square loop, the four hooks 84 can be hung on the hanging rings 85 on the corresponding first rigid pipe 31, the second rigid pipe 32, the third rigid pipe 33, and the fourth rigid pipe 34, thereby suspending the water supply pipe 3.

[0061] See Figure 3 The transmission assembly 9 includes a driving gear 91, a driven gear 92, and a transmission motor 93. The transmission motor 93 is fixedly installed inside the empty box 1 at the center surrounded by four vertical rods 81, and the output end of the transmission motor 93 is coaxially fixed with the driving gear 91. The driven gear 92 is coaxially fixedly sleeved on the vertical rod 81, located below the tray 82, and meshes with the driving gear 91.

[0062] When spraying curing is required on the concrete column, first hoist the empty box 1 to the top of the concrete column, then arrange the first pipe, the second rigid pipe 32, the third rigid pipe 33, and the fourth rigid pipe 34 into a square ring; then start the drive motor 93 to drive the drive gear 91 to rotate the driven gear 92, thereby driving the vertical rod 81 to release the suspension rope 83; after releasing to a certain extent, stop the drive motor 93 and separate the first rigid pipe 31 from the empty box 1, then hang the hook 84 on the corresponding hanging ring 85, and put the water supply pipe 3 on the concrete column (without contacting the concrete column), and finally start the drive motor 93 again to release the suspension rope 83, so that the water supply pipe 3 moves downward in the vertical direction to spray curing the concrete column.

[0063] The concrete spray curing system in this application can be switched according to the type of concrete to be sprayed (in this embodiment, it mainly targets concrete pavement and concrete columns). Unlike existing technologies, which require the construction of water pipes according to the type of concrete before spray curing, and the construction process is not only time-consuming but also cumbersome, the concrete spray curing system in this application has better applicability. Furthermore, when spray curing concrete pavement, if the pavement is long, the empty box 1 can be driven to move on the pavement, thus eliminating the need to construct long water pipes to spray the concrete pavement and reducing material usage.

[0064] See Figure 4 and Figure 5 A swing mechanism is provided between the nozzle 36 and its corresponding first rigid pipe 31, second rigid pipe 32, third rigid pipe 33 and fourth rigid pipe 34. The swing mechanism can drive the nozzle 36 to swing when spraying water to increase the spraying area and better spray the concrete column. The swing mechanism includes: swing component 2 and drive component 10.

[0065] See Figure 4The swing assembly 2 includes a push plate 21 and a connecting rod 22. The push plate 21 is fixed to the nozzle 36. One end of the connecting rod 22 is hinged to the side of the push plate 21 away from the nozzle 36, and the other end is connected to the rigid tubes (31, 32, 33, 34). In this embodiment, multiple nozzles 36 on the first rigid tube 31, the second rigid tube 32, the third rigid tube 33, and the fourth rigid tube 34 are jointly fixed to a single push plate 21.

[0066] See Figure 5 The drive assembly 10 includes a receiving plate 101, blades 102, a worm gear 103, a worm wheel 104, and a guide plate 105. The receiving plate 101 is fixed to the outer wall of the first rigid pipe 31, the second rigid pipe 32, the third rigid pipe 33, and the fourth rigid pipe 34. The worm wheel 104 is rotatably mounted on the receiving plate 101, and the end of the connecting rod 22 away from the push plate 21 is rotatably mounted on the side wall of the worm wheel 104.

[0067] See Figure 5 The guide plate 105 is fixedly installed inside the first rigid pipe 31, the second rigid pipe 32, the third rigid pipe 33, and the fourth rigid pipe 34, with a gap between the guide plate 105 and the inner bottom wall of the first rigid pipe 31, the second rigid pipe 32, the third rigid pipe 33, and the fourth rigid pipe 34 to allow water flow. One end of the worm gear 103 is rotatably installed inside the first rigid pipe 31, the second rigid pipe 32, the third rigid pipe 33, and the fourth rigid pipe 34 and is located to the side of the guide plate 105 and fixedly connected to the blade 102. The other end passes through the first rigid pipe 31, the second rigid pipe 32, the third rigid pipe 33, and the fourth rigid pipe 34 and meshes with the corresponding worm wheel 104. A sealing sleeve is fitted on the upper part of the worm gear 103 to improve the sealing between the worm gear 103 and the water supply pipe 3. The gap between the guide vane 105 and the inner bottom wall of the first rigid tube 31, the second rigid tube 32, the third rigid tube 33 and the fourth rigid tube 34 is aligned with the bottom of the blade 102.

[0068] After water is introduced into the first rigid pipe 31, the second rigid pipe 32, the third rigid pipe 33, and the fourth rigid pipe 34, the water flows through the gap between the guide plate 105 and the inner bottom wall of the first rigid pipe 31, the second rigid pipe 32, the third rigid pipe 33, and the fourth rigid pipe 34, and then strikes the blade 102, thereby causing the worm gear 103 to rotate. The rotation of the worm gear 103 will drive the worm wheel 104 to rotate, and through the setting of the connecting rod 22, it will push the push plate 21 to reciprocate. The push plate 21 will drive the nozzle 36 to swing, thereby increasing the spraying area of ​​the concrete pavement and better spraying the concrete columns. Moreover, there is no need to use an electric structure to drive the nozzle 36 to swing; simply introducing water is enough to immediately realize the swing of the nozzle 36.

[0069] In this embodiment, a temperature and humidity sensor and a controller can be installed on the empty box 1, and all electronic devices are connected to the controller so that the temperature and humidity sensor can detect the concrete. Once the detected temperature is high or the humidity is low, the water source is immediately controlled to enter the water supply pipe 3 to achieve the effect of automatic spraying.

[0070] The working principle of the concrete spray curing system in this application is as follows: If it is necessary to spray curing concrete columns, such as bridge piers, the retractor 65 is started to drive the retractor 62 to rotate. The retractor 62 can wind up one end of the retractor rope 63 after it has wrapped around the first rigid pipe 31, the second rigid pipe 32, the third rigid pipe 33 and the fourth rigid pipe 34, thereby pulling the second rigid pipe 32, the third rigid pipe 33 and the fourth rigid pipe 34 to rotate until they abut against the limiting plate 71, thus completing the winding. At this time, the first rigid pipe 31, the second rigid pipe 32, the third rigid pipe 33 and the fourth rigid pipe 34 are switched to form a square loop.

[0071] This application also provides a method for using a concrete spray curing system.

[0072] A method for using a concrete spray curing system includes the following steps:

[0073] S1: Adjust the state of water supply pipe 3 by operating the adjustment mechanism according to the concrete pattern;

[0074] S2: If spraying concrete pavement, water source is directly introduced into water supply pipe 3; if spraying concrete columns, a suspension mechanism is required to suspend water supply pipe 3 below.

[0075] S3: After water is supplied, the spray pipe 36 will automatically swing through the swing mechanism to spray and cure the concrete.

[0076] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
