Description

Technical Field

[0001] This invention relates to the field of building engineering technology, and in particular to a concrete curing device for building engineering. Background Technology

[0002] Concrete is widely used in the field of construction engineering. Usually, after the concrete is poured, it needs to be sprayed with water to make it solidify. For example, the curing of concrete components of viaducts and curved concrete components of tunnels requires spraying water to make them solidify.

[0003] However, traditional curing devices are usually manually operated handheld sprayers to cure concrete components of viaducts or curved concrete components of tunnels, which is time-consuming and labor-intensive. In addition, traditional curing devices can only spray and cure single concrete components of viaducts or curved concrete components of tunnels, and cannot change the usage state of the device as needed, which limits their practicality. Therefore, this invention proposes a concrete curing device for building engineering. Summary of the Invention

[0019] 2. By setting up a flipping structure in conjunction with a curing structure, the angle position of the second movable plate can be further adjusted. Under the action of the first motor, the gear transmission component 2 and the gear transmission component 1 mesh and move, causing the second movable plate to flip. The second movable plate, together with the first movable plate, can make the fixed seat, the first movable plate, and the second movable plate form a parabolic shape, thereby matching the internal rotation of the device and the tunnel arc concrete component, which is convenient for subsequent spraying and curing work.

[0020] 3.

This allows the device to change its usage form according to the needs of use, facilitating the later curing work of the tunnel's arc-shaped concrete components.

[0021] 4. By setting up a film protection structure in conjunction with a curing structure, it is beneficial to enable the device to immediately apply a film protection to the upper surface of the viaduct concrete components after spraying water, thereby further improving the solidification effect of the viaduct concrete components.

[0022] 5. By setting up a side-covering membrane component in conjunction with the membrane protection structure, it is beneficial to enable the device to immediately cover the sides of the viaduct concrete components after spraying water, thereby further improving the solidification effect of the viaduct concrete components.

[0023] 6. By setting up control component two in conjunction with the side film covering component, the device can be adaptively adjusted according to the side shape of the viaduct concrete component, thereby improving the device's adaptability and enabling it to better adapt to viaduct concrete components with vertical or inclined sides.

[0036] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0037] like Figures 1-11 As shown, a concrete curing device for building engineering includes four walking mechanisms 1, and a curing structure 2 is provided between the exterior of the four walking mechanisms 1.

[0038] The maintenance structure 2 includes four electric telescopic rods 5, two support plates 6, four connectors 14, and two connecting plates 17. A crossbar 7 is fixedly installed between the two support plates 6. A movable tube 8 is rotatably installed outside the crossbar 7. A baffle 16 and two fixed seats 9 are fixedly installed outside the movable tube 8. Movable plates 10 are rotatably installed at both ends of the fixed seats 9. Movable plate 2 11 is rotatably installed at one end of movable plate 10. Spray pipes 12 are fixedly installed outside both movable plates 10 and movable plate 2 11. Several nozzles 13 are fixedly installed outside the spray pipes 12. Adjacent spray pipes 12 are connected by connecting hoses 15. The baffle 16 and the two connecting plates 17 are rotatably connected by two electric push rods 18. The electric push rods 18 act on the connecting plates 17 to adjust the angle of the corresponding movable plates 10.

[0039] The curing structure 2 allows the device to simultaneously spray water on the upper surface and sides of the viaduct concrete components, further solidifying the concrete components and improving curing efficiency. The angle of the movable plate 10 can be adjusted as needed, allowing the device to spray the corners of the viaduct concrete components and increase the spray coverage.

[0040] In this embodiment, the maintenance structure 2 also includes two connecting seats 19. The two ends of the connecting seats 19 are fixedly connected to two walking mechanisms 1 at corresponding positions. A water tank 20 is fixedly installed on the inner side of the connecting seat 19. A water inlet 21 and a water pump 22 are installed on the outside of the water tank 20. A water distribution pipe 23 is installed on the outside of the water pump 22. Before use, a water pipe is connected between the water distribution pipe 23 and the connector 14 at the corresponding position.

[0041] The water inside the water tank 20 can be transported to the inside of the spray pipe 12 by the external water pipe and the water pump 22, so that the water can be sprayed out by the nozzle 13 for maintenance work.

[0042] In this embodiment, the electric telescopic rod 5 is set outside the walking mechanism 1 at the corresponding position, and one end of the two electric telescopic rods 5 on the same side is fixedly connected by the support plate 6.

[0043] The walking mechanism 1 enables the entire device to move, and the electric telescopic rod 5 can adjust the overall height of the device.

[0044] In this embodiment, the connector 14 is located at one end of the spray pipe 12 outside the movable plate 11 at the corresponding position, and the connecting plate 17 is fixedly connected to the two movable plates 10 at the corresponding positions.

[0045] With an external water pipe connected, the water pump 22 pumps water from the water tank 20 into the spray pipe 12.

[0046] In this embodiment, a flip structure 3 is provided on the outside of the connecting plate 17. The flip structure 3 acts to rotate the movable plate 11 for angle adjustment. The flip structure 3 includes two mounting plates 24 and a gear transmission component 25. The mounting plates 24 and the connecting plate 17 are fixedly connected. The two ends of the gear transmission component 25 are fixedly connected to the two movable plates 11 at corresponding positions. A gear transmission component 26 is rotatably arranged between the two mounting plates 24. One end of the gear transmission component 26 passes through one of the mounting plates 24 and is fixedly connected to the output shaft of the motor 27. The gear transmission component 25 and the gear transmission component 26 are meshed together.

[0047] The flipping structure 3, in conjunction with the curing structure 2, allows the angle of the movable plate 11 to be further adjusted. Under the action of the motor 27, the gear transmission components 26 and 25 mesh and move, causing the movable plate 11 to flip. The movable plate 11, in conjunction with the movable plate 10, allows the fixed base 9, the movable plate 10, and the movable plate 11 to form a parabolic shape, thereby matching the internal rotation of the device and the tunnel's arc-shaped concrete component, facilitating subsequent spraying and curing work.

[0048] In this embodiment, a control component 1 is provided on the outside of the movable tube 8. The control component 1 acts on the movable tube 8 to adjust the angle. The control component 1 includes two gear rings 28 and two base plates 29. The gear rings 28 are fixedly connected to the movable tube 8, and the base plates 29 are fixedly connected to the support plate 6. A motor 30 is provided on the outside of the base plate 29, and the output shaft of the motor 30 passes through the base plate 29 and is fixedly connected to a gear 31. The gear 31 and the gear rings 28 are meshed together.

[0049] The control component, together with the flipping structure 3 and the curing structure 2, allows the movable pipe 8 to rotate, thereby changing the nozzle 13 from its original inward orientation to its outward orientation. This allows the device to change its usage form according to the needs of use, facilitating the later curing of the tunnel's curved concrete components.

[0050] In this embodiment, a protective film structure 4 is provided on the outside of one of the support plates 6. The protective film structure 4 includes two fixed plates 32, which are fixedly connected to the support plate 6. A protective film roller 33 is rotatably arranged between the two fixed plates 32. A base plate 34 is fixedly arranged on the outside of the fixed plate 32. An electric push rod 35 is arranged on the outside of the base plate 34. One end of the two electric push rods 35 is fixedly connected through a fixing frame 36. A pressure roller 37 is rotatably arranged on the outside of the fixing frame 36.

[0051] The film protection structure 4, in conjunction with the curing structure 2, enables the device to immediately apply a film protection coating to the upper surface of the viaduct concrete components after spraying water, further improving the curing effect of the viaduct concrete components.

[0052] In this embodiment, the protective film structure 4 also includes two sets of side film coating components. The side film coating components include a base 38, which is fixedly connected to a support plate 6. A movable frame 39 is rotatably disposed through the inner side of the base 38. A protective film roller 40 is rotatably disposed on the outer side of the movable frame 39. The movable frame 39 is connected to a threaded rod 41 by a thread. One end of the threaded rod 41 is rotatably connected to a shelf 42. A pressure roller 43 is rotatably disposed on the inner side of the shelf 42. Two guide rods 44 are fixedly disposed on the outer side of the shelf 42, and the movable frame 39 is penetrated by the guide rods 44.

[0053] The side-coating assembly, in conjunction with the coating protection structure 4, allows the device to immediately apply a coating to the sides of the viaduct concrete components after water spraying, further improving the solidification effect of the viaduct concrete components.

[0054] In this embodiment, the film-coated protective structure 4 also includes two sets of control components 2. The control components 2 act on the movable frame 39 to adjust the angle. The control components 2 include gear 2 45 and electric push rod 3 46. Gear 2 45 and the corresponding movable frame 39 are fixedly connected. Electric push rod 3 46 is set outside the fixed plate 32. One end of electric push rod 3 46 is fixedly connected to push plate 47, and push plate 47 is fixedly connected to serrated plate 48. Serrated plate 48 and gear 2 45 are meshed together.

[0055] The control component 2, in conjunction with the side-covering component, allows the device to be adaptively adjusted according to the side shape of the viaduct concrete component, thereby improving the device's adaptability and enabling it to better fit viaduct concrete components with vertical or inclined sides.

[0056] In this embodiment, the fixed base 9, movable plate one 10, and movable plate two 11 are U-shaped in the initial state.

[0057] In its initial state, the device can perform curing work on the concrete components of the viaduct.

[0058] It should be noted that this invention is a concrete curing device for building engineering. Before use, simply place the device in the required location to bring it into operation. Figure 1 This represents the initial state of the device.

[0059] When curing of the elevated bridge concrete components is required, and the sides and top surfaces of the elevated bridge concrete components are perpendicular, in the initial state of the device, before use, connect an external water pipe between the water distribution pipe 23 and the corresponding connector 14. Based on the height of the elevated bridge concrete components, activate the electric telescopic rod 5 to move the support plate 6 to the predetermined height and then stop. Pull out the protective film on the protective film roller 33 so that one end adheres to the top surface of the elevated bridge concrete component. Activate the electric push rod 35 so that the pressure roller 37 presses the protective film onto the elevated bridge concrete. After the concrete component is placed on its upper surface, the protective film of the protective film roller 40 is pulled out and placed against the side of the viaduct concrete component. The threaded rod 41 is rotated so that the pressure roller 43 presses the protective film against the side of the viaduct concrete component and then stops. The traveling mechanism 1 is started to move the device. The water pump 22 is started to pump water from the water tank 20 into the spray pipe 12, and then sprayed out by the nozzle 13 to spray the upper surface and both sides of the viaduct concrete component simultaneously. Simultaneously, the protective films on protective film rollers 33 and 40 cover the upper and sides of the water-sprayed viaduct concrete components, further accelerating the solidification efficiency of the viaduct concrete components. Furthermore, when the sides of the viaduct concrete components tilt, the electric push rod 46 is activated to move the push plate 47 along with the toothed plate 48, causing the toothed plate 48 and gear 45 to mesh and move until the movable frame 39 gradually rotates and tilts to a predetermined angle and then stops. At this point, the movable frame 39 and protective film rollers 40... The pressure roller 43 and the side inclination angle of the viaduct concrete component are matched so that water spraying and film covering can be carried out. In the end, the upper surface and side of the viaduct concrete component are sprayed with water and solidified, and covered with a protective film to improve the solidification effect. In addition, the angle position of the movable plate 10 can be adjusted by the electric push rod 18 as needed, so that the movable plate 10 is tilted and the corresponding nozzle 13 on the movable plate 10 can spray the corners on both sides of the viaduct concrete component, thereby increasing the spray coverage of the device.

[0060] When water needs to be sprayed onto the curved concrete components of the tunnel to solidify them, in the initial state of the device, motor 30 is started, causing gear 31 and gear ring 28 to mesh, thereby rotating the movable pipe 8 180 degrees and stopping. Then, electric push rod 18 is activated to retract, causing connecting plate 17 to rotate the corresponding movable plate 10 by a predetermined angle and stop. Since the two adjacent spray pipes 12 are connected by connecting hose 15, the two adjacent spray pipes 12 will not interfere with each other during the rotation of movable plate 10. At this time, the fixed base 9 is parallel to the ground, one end of the two movable plates 10 is tilted towards the ground, and the two movable plates 10 are arranged in a V-shape. Next, start motor 27 to engage gear transmission component 26 and gear transmission component 25 until gear transmission component 25 rotates the corresponding movable plate 11 to a predetermined angle and stops. At this time, the fixed base 9, movable plate 10, and movable plate 11 are arranged in a parabolic shape to match the inner shape of the tunnel arc concrete component. Before use, connect an external water pipe between the water distribution pipe 23 and the corresponding connector 14. According to the inner height of the tunnel arc concrete component, the device reaches the predetermined height and stops after the electric telescopic rod 5 is used. Start the walking mechanism 1 to move. Finally, the water pump 22 sprays the nozzle 13 onto the tunnel arc concrete component to make it solidify.
