[0002] With the acceleration of urbanization, the construction industry has developed rapidly, especially the demand for high-rise buildings has increased. During the construction process, spray curing of cast-in-place concrete is one of the key steps to ensure the quality and strength of concrete.

[0003] At present, the main spraying method for cast-in-place concrete in building interiors is manual spraying. During spraying, water is sprayed on the cast-in-place concrete by connecting a water pipe to a water source. However, for manual spraying, the spraying range of the water pipe is limited, making the spraying process cumbersome and time-consuming. Summary of the invention

[0026] The following is combined with Figure 1-9 This application is described in further detail.

[0027] The embodiment of the present application discloses a spray curing device for cast-in-place concrete.

[0028] See also Figure 1 The spray maintenance device includes a spray vehicle 1, which includes a vehicle body 11, wheels 12 and a push rod 13. The vehicle body 11 is a square plate structure, and there are four wheels 12, which are respectively installed at the four corners of the bottom of the vehicle body 11. The wheels 12 are universal wheel structures, and the wheels 12 roll on the ground. The push rod 13 is fixed on the top of the vehicle body 11 and is tilted. When in use, the vehicle body 11 is pushed to move on the ground by the push rod 13.

[0029] See also Figure 2 and Figure 3 The spray curing device further includes a spray pipe 3, which includes a first spray pipe 31 and a second spray pipe 32. Two fixing plates are symmetrically fixed on the top of the vehicle body 11, and a connecting shaft 14 is rotatably connected between the fixing plates. The first spray pipe 31 is a long columnar structure, and the first spray pipe 31 is fixedly connected to the outer peripheral side of the connecting shaft 14, and the first spray pipe 31 can be turned up and down.

[0030] The first hinge shaft is rotatably connected to the vertical side wall of one side of the first spray pipe 31, and there is friction between the first hinge shaft and the first spray pipe 31, so that the first hinge shaft needs to apply force to rotate. The first hinge shaft is fixedly connected to the connecting column 4, which extends in the horizontal direction and is located at the position of the first spray pipe 31 close to the vehicle body 11. The connecting column 4 is a long columnar structure, and the connecting column 4 can be flipped to a state parallel to the first spray pipe 31 or perpendicular to the first spray pipe 31. The second spray pipe 32 is a long columnar structure, and the connecting column 4 is rotatably connected to the second hinge shaft on the side away from the first spray pipe 31, and there is friction between the second hinge shaft and the connecting column 4, so that the second hinge shaft needs to apply force to rotate. The second spray pipe 32 is fixed to the second hinge shaft, and the second spray pipe 32 can be flipped to be in the same straight line with the connecting column 4 or in a vertical state with the connecting column 4.

[0031] See also Figure 1 and Figure 3 , a water delivery trough 33 is formed in the first spray pipe 31 and the second spray pipe 32, respectively, and the water delivery trough 33 extends along the length direction of the first spray pipe 31 and the second spray pipe 32. A plurality of atomizing spray holes 34 are formed at intervals on the outer walls of the first spray pipe 31 and the second spray pipe 32, respectively, and the atomizing spray holes 34 are connected to the water delivery trough 33. An atomizing plate is installed at the orifice position of the atomizing spray hole 34 away from the side of the water delivery trough 33, and a plurality of holes are formed on the atomizing plate at even intervals. When the water flow in the water delivery trough 33 passes through the atomizing spray hole 34, the water flow is atomized and then sprayed out. When the first spray pipe 31 and the second spray pipe 32 are in a horizontal state, the atomizing spray hole 34 is arranged downward. Moreover, when the connecting column 4 is perpendicular to the first spray pipe 31 and the second spray pipe 32 at the same time, the atomizing spray hole 34 of the first spray pipe 31 and the atomizing spray hole 34 of the second spray pipe 32 are arranged alternately.

[0032] The spray maintenance device also includes a water tank 2, which is fixedly mounted on the top of the vehicle body 11. A water tank 23 is formed inside the water tank 2 for storing water. A water inlet is formed on the top of the water tank 2, which is connected to the water tank 23, and external water flows into the water tank 23 through the water inlet.

[0033] See also Figure 2 A water pump 5 is fixedly installed in the water tank 2, and a waterproof battery is fixedly installed on the side wall of the water tank 2. The water pump 5 is electrically connected to the waterproof battery, and when in use, the waterproof battery provides energy to the water pump 5. In other embodiments, the water pump 5 can also be directly electrically connected to an external power source through wires.

[0034] See also Figure 2 and Figure 4The water storage tank 2 is fixedly provided with a transmission pipe 22, which is a hose structure. One side of the transmission pipe 22 is bifurcated into two water pipe structures, and the two pipe openings bifurcated from the transmission pipe 22 are respectively connected to the first spray pipe 31 and the second spray pipe 32 (the second spray pipe 32 is Figure 1 The water delivery trough 33 of the water tank 23 is marked with a mark in the middle, and the pipe opening of the transmission pipe 22 on one side away from the water delivery trough 33 is connected to the water outlet of the water pump 5. The water inlet of the water pump 5 is connected and fixed with a water inlet pipe 51. When the water pump 5 is started, the water pump 5 draws water from the water storage tank 23 through the water inlet pipe 51, and then transmits it to the water delivery trough 33 through the transmission pipe 22, and then the water is sprayed out through the atomizing spray hole 34 to spray the cast-in-place concrete.

[0035] See also Figure 5 and Figure 6 The spray maintenance device also includes a control component 6, which is arranged on the spray vehicle 1 and is used to control the first spray pipe 31 to flip up and down. The control component 6 includes a control worm 61 and a control worm wheel 62, and the control worm wheel 62 is fixedly connected to the outer peripheral side of the connecting shaft 14, and the control worm wheel 62 is rotatably connected to the spray vehicle 1. The control worm 61 is rotatably connected to the spray vehicle 1, and the control worm 61 is meshed with the control worm wheel 62 and meets the self-locking parameters. When in use, the control worm 61 is rotated to drive the control worm wheel 62 to turn, so that the first spray pipe 31 is flipped up and down, and the angle of the first spray pipe 31 can be adjusted to facilitate spraying the floor and side walls inside the building.

[0036] When it is necessary to spray the floor inside the building, the worm 61 is controlled to drive the worm wheel 62 to rotate, so that the first spray pipe 31 is flipped to a tilted state. At the same time, the connecting column 4 and the second spray pipe 32 are flipped so that the second spray pipe 32 is parallel to the first spray pipe 31, and the connecting column 4 is perpendicular to the first spray pipe 31 and the second spray pipe 32 respectively. At this time, the atomizing spray hole 34 is tilted toward the ground. When spraying, the spray vehicle 1 is pushed along the length direction of the connecting column 4, so that the spray vehicle 1 moves from the vertical wall on one side of the building to the vertical wall on the other side. At this time, the atomized water flow sprays the ground, and then the spray vehicle 1 is pushed on the horizontal plane along the length direction of the vertical connecting column 4, and then the spray vehicle 1 is pushed to spray the unsprayed ground according to the same steps, which greatly reduces the cumbersomeness of the spraying operation and improves the spraying speed.

[0037] When it is necessary to spray the vertical walls inside the building, the worm gear 62 is driven to rotate by controlling the worm 61, so that the first spray pipe 31 is flipped to a vertical state, and the connecting column 4 and the second spray pipe 32 are flipped at the same time, so that the connecting column 4 is parallel to the first spray pipe 31, and the second spray pipe 32 and the connecting column 4 are in the same straight line. At this time, the first spray pipe 31 and the second spray pipe 32 can respectively spray walls in different areas, which is beneficial to increase the spray range and greatly shorten the spray time.

[0038] See also Figure 4 and Figure 5 The spray pipes 3 are respectively inclined to form guide surfaces 35 , the guide surfaces 35 surround the atomizing spray holes 34 away from the opening on one side of the water delivery trough 33 , and the guide surfaces 35 correspond to the atomizing spray holes 34 one by one.

[0039] The spray pipe 3 is formed with a collecting groove 36, which is located on the guide surface 35 and extends in the circumferential direction. An input groove 37 is formed in the spray pipe 3, which is located below and connected to the collecting groove 36, and extends along the length direction of the spray pipe 3. A connecting groove 38 is formed in the spray pipe 3, which extends along an arc track, and the two sides of the connecting groove 38 are respectively connected to two adjacent input grooves 37.

[0040] See also Figure 3 and Figure 4 A water collecting tank 7 is fixedly installed on the spray vehicle 1. The water collecting tank 7 is adjacent to the water storage tank 2, and a water collecting tank 71 is formed in the water collecting tank 7. A connecting pipe 72 is fixedly installed on the water collecting tank 7, and the connecting pipe 72 connects the water collecting tank 71 and the connecting tank 38. A water delivery pipe 21 is fixedly connected between the water collecting tank 7 and the water storage tank 2. The water delivery pipe 21 connects the water collecting tank 71 and the water storage tank 23, and the water delivery pipe 21 is located away from the vehicle body 11. When the atomizing spray hole 34 sprays, part of the water mist condenses into water droplets on the hole wall of the atomizing spray hole 34, and then the water droplets flow into the collecting tank 36 along the atomizing spray hole 34 and the guide surface 35, and then flow into the water collecting tank 71 through the connecting pipe 72.

[0041] See also Figure 6 and Figure 7 A push plate 74 is slidably arranged in the water collecting tank 7. The push plate 74 includes an upper plate 741 and a lower plate 742. A slide groove 743 extending in the vertical direction is formed at the bottom of the upper plate 741. The slide groove 743 penetrates two opposite vertical side walls of the upper plate 741. The lower plate 742 slides up and down in the slide groove 743, and the side walls of the upper plate 741 and the lower plate 742 are respectively in sliding contact with the peripheral groove walls of the water collecting groove 71. The upper plate 741 is provided with a first sealing strip 7411. The first sealing strip 7411 is symmetrically arranged and respectively embedded and fixed on the opposite groove walls on the vertical side of the slide groove 743. The first sealing strip 7411 is in contact with the lower plate 742, so that a sealed connection is achieved between the upper plate 741 and the lower plate 742. The second sealing strips 744 are respectively embedded and fixed on the peripheral side walls of the upper plate 741 and the lower plate 742. The first sealing strips 7411 are respectively located between and adjacent to the two second sealing strips 744 on the opposite vertical side walls of the upper plate 741. The second sealing strips 744 are in sliding contact with the vertical groove walls on the opposite sides of the water collecting trough 71, so that sealing is achieved between the upper plate 741, the lower plate 742 and the groove walls of the water collecting trough 71.

[0042] The water collecting box 7 is rotatably connected with a reciprocating screw rod 73, which passes through the water collecting tank 71, and the upper plate 741 is threadedly connected with the reciprocating screw rod 73. The vertical side walls on both sides of the upper plate 741 are respectively fixedly connected with sealing covers 7412, which are accordion cover structures. The end of the sealing cover 7412 away from the upper plate 741 is fixedly connected to the wall of the water collecting tank 71, and the reciprocating screw rod 73 passes through the sealing cover 7412, which is conducive to reducing the possibility of water flowing through the gap between the reciprocating screw rod 73 and the upper plate 741.

[0043] See also Figure 8 and Fig. 9 The water storage tank 2 is provided with a driving assembly 8. When the water pump 5 pumps water, the driving assembly 8 drives the reciprocating screw 73 (the reciprocating screw 73 is Figure 7 The driving assembly 8 includes a driving shaft 81, a driving blade 82 and a driving belt 83. A driving block 52 is fixedly connected to the outer wall of the water inlet pipe 51. The driving block 52 and the wall of the water inlet pipe 51 are respectively formed with mutually connected driving grooves 53. The driving shaft 81 is rotatably connected to the driving block 52 and extends into the driving groove 53. The driving blade 82 is fixedly connected to the outer peripheral side of the driving shaft 81. There are multiple driving blades 82 and they are arranged at intervals along the circumferential direction. When the driving shaft 81 rotates to drive the driving blade 82 to move to the side close to the water inlet pipe 51, the driving blade 82 extends into the water inlet pipe 51. When the water pump 5 is started so that the water flow in the water storage tank 23 is pumped into the water inlet pipe 51, the water flow impacts the driving blade 82, driving the driving shaft 81 to rotate.

[0044] See also Figure 7 and Fig. 9 The drive shaft 81 extends out of the water tank 2 away from the side of the water inlet pipe 51, and the drive shaft 81 is rotatably connected to the water tank 2. The reciprocating screw 73 protrudes out of the water collecting tank 7, and the end of the reciprocating screw 73 protruding out of the water collecting tank 7 is adjacent to the end of the drive shaft 81 extending out of the water tank 2. The drive belt 83 is connected end to end and is sleeved on the outer circumference of the drive shaft 81 and the reciprocating screw 73. When the drive shaft 81 rotates, the drive belt 83 drives the reciprocating screw 73 to rotate, so that the upper plate 741 and the lower plate 742 reciprocate along the length direction of the reciprocating screw 73.

[0045] See also Figure 6 and Figure 7 When the upper plate 741 drives the lower plate 742 to move toward the side close to the water pipe 21, the upper plate 741 and the lower plate 742 squeeze the water flow in the water collecting tank 71 into the water pipe 21, and then the water flows into the water storage tank 2 through the water pipe 21.

[0046] The water collecting box 7 is provided with a pushing assembly. When the pushing plate 74 moves to the groove wall on one side of the water collecting groove 71, the pushing assembly pushes the lower plate 742 to slide upward on the upper plate 741; when the pushing plate 74 moves to the groove wall on the other side of the water collecting groove 71, the pushing assembly pushes the lower plate 742 to slide downward until it abuts against the bottom groove wall of the water collecting groove 71.

[0047] The push assembly includes a first push column 91, a second push column 92, a first magnet 93 and a second magnet 9; the first magnet 93 is fixedly connected to a vertical side wall of the upper plate 741, and the first magnet 93 extends in the vertical direction. The second magnet 9 is fixedly connected to a vertical side wall of the lower plate 742 facing the first magnet 93, and the second magnet 9 extends in the vertical direction. The first magnet 93 has opposite magnetic properties to the second magnet 9, and the first magnet 93 abuts against the second magnet 9, so that the upper plate 741 and the lower plate 742 are connected, reducing the possibility of the lower plate 742 sliding up and down in the slide groove 743 when no force is applied.

[0048] The first push column 91 is fixedly connected to the vertical groove wall on one side of the water collecting tank 71 facing the lower plate 742. The lower plate 742 is inclined toward the side of the first push column 91 and the bottom is formed with a first push surface 7421, and the first push surface 7421 corresponds to the first push column 91. When the upper plate 741 drives the lower plate 742 to approach the groove wall of the water collecting tank 71 where the first push column 91 is located, the first push column 91 slides on the first push surface 7421. At this time, the first push column 91 pushes the lower plate 742 to move upward, so that there is a gap between the bottom of the lower plate 742 and the groove wall at the bottom of the water collecting tank 71; and the first magnet 93 and the second magnet 9 remain in a state of abutting each other, which can maintain the state of the lower plate 742, so that the water flow on both sides of the lower plate 742 can flow.

[0049] The second push column 92 is fixedly connected to the groove wall of the water collecting groove 71 on one side facing the first push column 91. A push hole is formed on the upper plate 741 facing the second push column 92. The push hole is connected to the slide groove 743, and the push hole is aligned with the second push column 92. The top of the lower plate 742 is inclined to form a second push surface 7422. When the first push column 91 pushes the lower plate 742 to slide upward into the slide groove 743, the second push surface 7422 is aligned with the push hole.

[0050] When the lower plate 742 moves close to the vertical groove wall of the water collecting trough 71 where the second pushing column 92 is set, the second pushing column 92 passes through the pushing hole and slides on the second pushing surface 7422, pushing the lower plate 742 to move downward until it abuts against the bottom groove wall of the water collecting trough 71, so that when the upper plate 741 and the lower plate 742 approach the water pipe 21 again, the water flow can be squeezed into the water pipe 21.

[0051] The implementation principle of a spray curing device for cast-in-place concrete in the embodiment of the present application is as follows: When in use, water mist is sprayed through the atomizing spray holes 34 on the first spray pipe 31 and the second spray pipe 32 to spray the cast-in-place concrete, which is convenient for spraying the cast-in-place concrete in the building room and can greatly reduce the spraying time. During spraying, the water droplets condensed on the atomizing spray holes 34 are collected in the collecting tank 36 and flow into the water collecting tank 71 through the connecting pipe 72, and when the water pump 5 extracts the water flow in the water storage tank 23, the push plate 74 squeezes the water flow in the water collecting tank 71 into the water delivery pipe 21, and flows into the water storage tank 23 through the water delivery pipe 21, which is conducive to reducing the waste of water flow.

[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
