Description

Technical Field

[0001] This invention relates to the field of concrete curing equipment technology, and more specifically, to an energy-saving concrete curing equipment for bridge construction. Background Technology

[0002] With the rapid development of modern bridge construction, the application of precast bridge components is becoming increasingly widespread. After prefabrication in a factory, these components typically require thorough concrete curing to ensure their strength and durability. Concrete curing is a crucial step in guaranteeing concrete quality; improper curing can lead to cracks in the concrete, affecting the bridge's service life and safety.

[0003] Currently, the existing technologies for bridge concrete curing devices mainly employ the following methods: one is a fixed spraying device, which uses fixed nozzles installed above precast components for spraying curing; another is a simple mobile spraying device, which uses slide rails or guide rails to move the nozzles in one direction for spraying; and the third is a tunnel-type curing kiln, which uses steam or spray to cure the components as a whole.

[0004] However, for T-shaped precast bridge components with upward-curving grooves or corners on both sides, their complex structures create numerous blind spots. For example, conventional spraying devices cannot directly target areas such as the area below the flanges of T-shaped components, the concave grooves on both sides, and the corners, leading to insufficient concrete curing and a tendency for cracks. In existing technologies, even mobile spraying devices can only move in one or two directions, failing to effectively cover all blind spots in complex-shaped components. Furthermore, existing curing devices typically employ large-area coverage spraying, which cannot precisely spray according to the actual needs of the component, resulting in significant waste of curing water and failing to meet energy-saving requirements. Summary of the Invention

[0005] This invention provides an energy-saving concrete curing device for bridge construction, which solves the technical problems in related technologies that make it impossible to effectively spray and cure the dead corner areas of T-shaped bridge precast components with upward concave grooves or corners on both sides, resulting in cracks in the concrete in the dead corner areas due to insufficient curing, and that it is impossible to spray precisely according to the actual needs of the components, resulting in serious waste of curing water.

[0006] This invention provides an energy-saving concrete curing device for bridge structures, comprising a main body, which includes a support unit and a gantry frame. The curing unit is connected to the gantry frame via an X, Y, and Z axis drive system. A precast bridge component is placed on the support unit, and the curing unit performs spray curing on the precast bridge component. The curing unit includes a dual-position moving mechanism, a dead-angle spraying mechanism, a top surface spraying mechanism, and a side spraying mechanism. The dual-position moving mechanism drives two sets of dead-angle spraying mechanisms to move to both sides to adapt to the width of the precast bridge component. The dead-angle spraying mechanism is used to spray curing the dead-angle areas of the precast bridge component. The top surface spraying mechanism and the side spraying mechanism are used to spray curing the top and sides of the precast bridge component to prevent cracks from forming.

[0007] As a further optimization of the present invention, the bearing unit includes a base, on which a bearing platform is installed. The bearing platform is provided with multiple sets of first hydraulic cylinders inside, and the fixed ends of the first hydraulic cylinders are installed on the base. The bearing platform is provided with several openings, and each opening is provided with a top plate. The telescopic ends of every two sets of first hydraulic cylinders are fixedly connected to the top plate.

[0008] As a further optimization of the present invention, the upper surface of the support platform and the upper surface of the top plate are on the same plane, and the support platform and the top plate are in contact with the bottom surface of the bridge precast component; when the first hydraulic cylinder drives the top plate to lift upward, it drives the bridge precast component to move upward, so that the side spraying mechanism can spray and cure the bottom of the bridge precast component.

[0009] As a further optimization of the present invention, the dual-station moving mechanism includes a support frame mounted on a second moving frame. Sliding frames are slidably connected to both sides of the support frame, and motors are mounted on the sliding frames. First gears are mounted on the output shafts of both sets of motors, and first racks are meshed on the first gears. The first racks are fixedly connected to the support frame.

[0010] As a further optimization of the present invention, the dead-angle spraying mechanism includes a second hydraulic cylinder mounted on a sliding frame. A telescopic frame is mounted on the telescopic end of the second hydraulic cylinder, and a fixed frame is mounted on the telescopic frame. An electric push rod is mounted on the fixed frame, and a second rack is mounted on the telescopic end of the electric push rod. A second gear is meshed on the second rack, and a connecting shaft is mounted on the second gear. The connecting shaft and the fixed frame are rotatably connected by a bearing. One end of the connecting shaft passes through the fixed frame and is mounted on a connecting plate. A first spray pipe is provided on the connecting plate. Multiple sets of first nozzles are evenly distributed on the side of the first spray pipe facing the bridge precast component, and the first nozzles are connected to the inside of the first spray pipe. A first connector is also mounted on the first spray pipe.

[0011] As a further optimization of the present invention, the first spray pipe is arranged in an arc shape.

[0012] As a further optimization of the present invention, the top surface spraying mechanism includes a second spraying pipe installed at the bottom of the support frame, and multiple sets of second nozzles are evenly distributed on the side of the second spraying pipe facing the bridge precast component. The second nozzles are connected to the interior of the second spraying pipe, and a second connector is also installed on the second spraying pipe.

[0013] As a further optimization of the present invention, the side spraying mechanism includes a third spraying pipe disposed on both sides of the support frame. Multiple sets of third nozzles are evenly distributed on the side of the third spraying pipe facing the bridge precast component, and the third nozzles are connected to the interior of the third spraying pipe. A third connector is also installed on the third spraying pipe.

[0014] As a further optimization of the present invention, the third spray pipe is slidably connected to a sliding sleeve, and the sliding sleeve is mounted on a support frame, and a spring is provided on the outside of the third spray pipe.

[0015] As a further optimization of the present invention, the end of the third spray pipe away from the third connector is rotatably connected to a roller via a bearing.

[0016] The beneficial effects of this invention are as follows: By setting up a dual-station moving mechanism to drive two sets of dead-angle spraying mechanisms to move to both sides, the invention precisely adapts to the width of the bridge precast components. The dead-angle spraying mechanism adopts an arc-shaped first spray pipe, combined with height and angle adjustment functions, enabling precise spraying and curing of dead-angle areas that conventional spraying cannot cover, such as the area below the flanges of T-shaped components and the concave grooves on both sides, effectively preventing cracks caused by insufficient curing in these areas. Furthermore, through the cooperation of the top surface spraying mechanism, the side spraying mechanism, and the dead-angle spraying mechanism, uniform spraying and curing of the entire surface of the component is achieved, ensuring comprehensive coverage of the curing water without any missed areas, resulting in excellent curing effects. Additionally, by using a first hydraulic cylinder inside the bearing unit to drive the top plate upwards, the bridge precast components move upwards, creating a gap between the bottom of the component and the bearing platform. This facilitates the side spraying mechanism to spray and cure the bottom of the component, ensuring no dead-angles in the bottom curing and preventing cracks caused by inadequate curing.

[0019] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and implement the subject matter described herein, and changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0020] According to the appendix Figure 1 and attached Figure 10 As shown, the present invention provides an energy-saving concrete curing device for bridge construction, including a main body of the device, which includes a load-bearing unit 100 and a gantry frame 200.

[0021] The bearing unit 100 is used to support the bridge prefabricated component 300. It includes a base 110 and a bearing platform 120. The base 110 is the basic support structure of the entire device and is installed on the ground or working surface to ensure the stability of the device. The bearing platform 120 is installed above the base 110 and is used to place the bridge prefabricated component 300.

[0022] The support platform 120 is equipped with multiple sets of first hydraulic cylinders 130. The fixed end of the first hydraulic cylinder 130 is installed on the base 110. The support platform 120 has several openings, and each opening is equipped with a top plate 140. The telescopic ends of every two sets of first hydraulic cylinders 130 are fixedly connected to the top plate 140.

[0023] It should be understood that when the telescopic end of the first hydraulic cylinder 130 extends upward, it pushes the top plate 140 to move upward, thereby driving the bridge precast component 300 placed on the support platform 120 to move upward, forming a spray gap between the bottom of the component and the support platform 120, which facilitates spray curing of the bottom of the component.

[0024] Preferably, the upper surface of the support platform 120 and the upper surface of the top plate 140 are on the same plane, and the support platform 120 and the top plate 140 are in contact with the bottom surface of the bridge precast component 300 to achieve stable placement and support of the component. When the first hydraulic cylinder 130 drives the top plate 140 to lift upward, it drives the bridge precast component 300 to move upward, so that the side spraying mechanism 840 can spray and cure the bottom of the bridge precast component 300.

[0025] Specifically, the gantry 200 is a support and guide structure for the maintenance unit 800, located on both sides or around the bearing unit 100. The maintenance unit 800 is connected to the gantry 200 through an X, Y, Z axis drive system. The X, Y, Z axis drive system includes a Y axis drive mechanism 500 and an XZ axis drive mechanism 700.

[0026] It should be noted that a first movable frame 400 is provided on the gantry 200, and a Y-axis drive mechanism 500 is provided between the first movable frame 400 and the gantry 200. Driven by the Y-axis drive mechanism 500, the first movable frame 400 can move along the Y-axis direction of the gantry 200, that is, along the length direction of the bridge precast component 300, thereby driving the maintenance unit 800 to cover the length direction of the component.

[0027] A second moving frame 600 is mounted on the first moving frame 400. An XZ-axis drive mechanism 700 is positioned between the first moving frame 400 and the second moving frame 600. Driven by the XZ-axis drive mechanism 700, the second moving frame 600 can move along the first moving frame 400 in the X and Z axes, i.e., the width and vertical directions of the precast bridge component 300, allowing the maintenance unit 800 to be precisely aligned with the area to be maintained on the component. The X, Y, and Z-axis drive system enables the maintenance unit 800 to achieve precise movement and positioning in three-dimensional space, achieving comprehensive coverage of the maintenance areas at different locations.

[0028] According to the appendix Figure 1 To be continued Figure 6 As shown, the curing unit 800 is the core component of this invention. It is connected to the gantry 200 via an X, Y, and Z axis drive system and its position is adjusted in three-dimensional space as the moving frame moves. The curing unit 800 includes a dual-station moving mechanism 810, a dead-angle spraying mechanism 820, a top surface spraying mechanism 830, and a side spraying mechanism 840, realizing full-surface curing of the bridge precast components 300.

[0029] Specifically, the dual-station moving mechanism 810 includes a support frame 811 mounted on the second moving frame 600. Sliding frames 812 are slidably connected to both sides of the support frame 811, and motors 813 are mounted on the sliding frames 812. First gears 814 are mounted on the output shafts of both sets of motors 813, and first racks 815 are meshed on the first gears 814. The first racks 815 are fixedly connected to the support frame 811.

[0030] It is important to understand that when the motor 813 starts, its output shaft drives the first gear 814 to rotate. Since the first gear 814 meshes with the first rack 815 fixed on the support frame 811, it drives the two sets of sliding frames 812 to slide along the guide rails on both sides of the support frame 811, thereby realizing the synchronous movement of the two sets of dead angle spraying mechanisms 820 to the sides or inside, and accurately adapting to the bridge prefabricated components 300 of different widths.

[0031] Preferably, guide rails are installed on both the upper and lower sides of the support frame 811, and multiple sets of guide wheels are slidably connected to the guide rails. These guide wheels are rotatably connected to the sliding frame 812 via bearings. The guide wheels ensure the stability of the sliding frame 812 during movement, reduce friction and vibration, and ensure positioning accuracy. The guide rails are made of high-strength steel with a hardened surface, exhibiting good wear resistance and stability. The guide wheels are connected by bearings, allowing for flexible rotation and effectively reducing resistance during sliding.

[0032] According to the appendix Figure 3 To be continued Figure 9 As shown, the dead-angle spraying mechanism 820 is a key component of this invention for solving the maintenance problem of T-shaped bridge prefabricated components 300 with upward concave grooves or corners on both sides. The dead-angle spraying mechanism 820 includes a second hydraulic cylinder 821 mounted on a sliding frame 812. A telescopic frame 822 is mounted on the telescopic end of the second hydraulic cylinder 821, and a fixed frame 823 is mounted on the telescopic frame 822. An electric push rod 824 is mounted on the fixed frame 823, and a second rack 825 is mounted on the telescopic end of the electric push rod 824. A second gear 826 is meshed on the second rack 825, and a connecting shaft 827 is mounted on the second gear 826. The connecting shaft 827 and the fixed frame 823 are rotatably connected by a bearing, enabling the connecting shaft 827 to rotate flexibly relative to the fixed frame 823. One end of the connecting shaft 827 passes through the fixed frame 823 and is mounted on a connecting plate 828. A first spray pipe 829 is detachably connected to the connecting plate 828. The connecting plate 828 and the first spray pipe 829 are connected by bolts to facilitate adjustment of the setting angle of the first spray pipe 829. The detachable connection design allows the angle of the first spray pipe 829 to be finely adjusted according to actual maintenance needs, adapting to dead corner areas of components of different shapes, and also facilitating later maintenance and replacement.

[0033] Specifically, the first spray pipe 829 has an arc-shaped structure, with multiple sets of first nozzles 8210 evenly distributed on the side facing the bridge precast component 300, and the first nozzles 8210 are connected to the interior of the first spray pipe 829. A first connector 8211 is also installed on the first spray pipe 829 for connecting to an external curing water supply system. The arc-shaped structure of the first spray pipe 829 better adapts to the corners of the T-shaped component and the contours of the concave grooves on both sides, and the multiple sets of first nozzles 8210 can fully cover blind spots, achieving thorough spraying.

[0034] It should be noted that during operation, the extension and retraction of the second hydraulic cylinder 821 drives the telescopic frame 822, the fixed frame 823, and subsequent components to move in the Z-axis direction, delivering the arc-shaped first spray pipe 829 to the corresponding height of the dead corner area of ​​the component; secondly, the extension and retraction of the electric push rod 824 drives the second rack 825 to move, and the second rack 825 meshes with the second gear 826, driving the connecting shaft 827 to rotate around the fixed frame 823, thereby driving the connecting plate 828 and the first spray pipe 829 to rotate and adjust the spray angle; finally, curing water is introduced into the first spray pipe 829 through the first connector 8211, and the curing water is sprayed out through multiple sets of evenly distributed first nozzles 8210 to continuously and evenly spray and cure the dead corner area of ​​the component. Through the combined use of height and angle adjustments, the blind spot spraying mechanism 820 can accurately target and cover blind spot areas that conventional spraying cannot cover, such as the area below the flange of the T-shaped component and the concave grooves on both sides, effectively solving the technical problem of difficult maintenance of blind spot areas in the existing technology.

[0035] According to the appendix Figure 2 and attached Figure 5 As shown, the top spraying mechanism 830 includes a second spray pipe 831 installed at the bottom of the support frame 811, and multiple sets of second nozzles 832 are evenly distributed on the side of the second spray pipe 831 facing the bridge precast component 300. The second nozzles 832 are connected to the interior of the second spray pipe 831. A second connector 833 is also installed on the second spray pipe 831 for connecting to an external maintenance water supply system.

[0036] It should be understood that curing water is introduced into the second spray pipe 831 through the second connector 833, and the curing water is evenly sprayed onto the top surface of the bridge precast component 300 through multiple sets of evenly distributed second nozzles 832, ensuring uniform curing of the top surface of the component. The even distribution design of the second nozzles 832 makes the spray coverage wide and without any missed areas.

[0037] According to the appendix Figure 3 To be continued Figure 5As shown, the side spraying mechanism 840 includes a third spray pipe 841 disposed on both sides of the support frame 811. Multiple sets of third nozzles 842 are evenly distributed on the side of the third spray pipe 841 facing the bridge precast component 300, and the third nozzles 842 are connected to the interior of the third spray pipe 841. A third connector 843 is also installed on the third spray pipe 841.

[0038] Specifically, a sliding sleeve 844 is slidably connected to the outside of the third spray pipe 841, and the sliding sleeve 844 is mounted on the support frame 811. A spring 845 is provided on the outside of the third spray pipe 841, with one end of the spring 845 fixedly connected to the sliding sleeve 844 and the other end of the spring 845 fixedly connected to the outer wall of the third spray pipe 841. The spring 845 allows the third spray pipe 841 to be cushioned when it descends to the bottom and contacts the ground, facilitating spray curing of the bottom of the bridge precast component 300 and improving the spraying effect.

[0039] The third spray pipe 841 is provided with a sliding section for the sliding sleeve 844 to slide outside the third spray pipe 841. This sliding section does not have a third nozzle 842, thus facilitating the extension and retraction of the third spray pipe 841 inside the sliding sleeve 844 to adapt to components of different widths. In addition, a roller 846 is rotatably connected to the end of the third spray pipe 841 away from the third connector 843 via a bearing. The roller 846 is used for sliding on the ground.

[0040] It should be understood that curing water is introduced into the third spray pipe 841 through the third connector 843, and the curing water is sprayed on both sides of the component through multiple sets of third nozzles 842.

[0041] According to the appendix Figure 1 To be continued Figure 10 As shown, the working principle of an energy-saving bridge concrete curing device is as follows: First, the precast bridge component 300 to be cured is stably placed on the support platform 120 of the support unit 100. At this time, the upper surface of the support platform 120 and the upper surface of the top plate 140 are kept on the same plane, and are in full contact with the bottom surface of the precast bridge component 300, so as to achieve stable support and positioning of the component. The first hydraulic cylinder 130 in the base 110 is in the retracted state, reserving adjustment space for subsequent bottom curing of the component. At the same time, the X, Y, and Z axis drive systems on the gantry 200 and the curing unit 800 are initialized, and each mechanism is in a ready-to-work state.

[0042] To achieve full coverage of the bridge precast components 300 by the maintenance unit 800, the maintenance unit 800 is driven to move precisely in three-dimensional space by the X, Y, and Z axis drive system.

[0043] The first movable frame 400 is driven to move along the Y-axis direction of the gantry 200 by the Y-axis drive mechanism 500 between the gantry 200 and the first movable frame 400, thereby driving the maintenance unit 800 to cover the length direction of the component.

[0044] The XZ axis drive mechanism 700 between the first moving frame 400 and the second moving frame 600 drives the second moving frame 600 to move along the X and Z axes of the first moving frame 400, so that the curing unit 800 is precisely aligned with the area to be cured of the component, thus preparing the position for spraying the top surface, sides and dead corner areas.

[0045] The curing unit 800 achieves full surface curing of components through the coordinated operation of the dual-station moving mechanism 810, the dead corner spraying mechanism 820, the top spraying mechanism 830, and the side spraying mechanism 840, with a focus on solving the spraying problem in dead corner areas.

[0046] During operation, the dual-station moving mechanism 810 is activated and adjusted according to the actual width of the precast bridge component 300. The motors 813 on both sides of the support frame 811 operate, driving the first gear 814 on the output shaft to rotate. Since the first gear 814 meshes with the first rack 815 fixed on the support frame 811, it drives the two sets of sliding frames 812 to slide along the guide rails on both sides of the support frame 811, so that the two sets of dead angle spraying mechanisms 820 move synchronously to the sides or inside, accurately matching the width of the component, and ensuring that the dead angle spraying mechanism 820 can be aligned with the corners, concave grooves and other dead angle areas on both sides of the component.

[0047] During operation, the blind spot spraying mechanism 820 achieves precise spraying by adjusting in multiple dimensions to cover areas that conventional spraying cannot reach, such as the area below the flange of the T-shaped component and the concave grooves on both sides.

[0048] During operation, the second hydraulic cylinder 821 on the sliding frame 812 is activated, and the telescopic end drives the telescopic frame 822, the fixed frame 823 and subsequent components to move downward, sending the arc-shaped first spray pipe 829 to the corresponding height of the dead corner area of ​​the component, ensuring that the first nozzle 8210 can be aligned with the dead corner position.

[0049] Subsequently, the electric push rod 824 is activated, and the telescopic end drives the second rack 825 to move. The second rack 825 meshes with the second gear 826, driving the connecting shaft 827 to rotate around the fixed frame 823, which in turn drives the connecting plate 828 and the first spray pipe 829 to rotate, adjusting the spray angle of the first spray pipe 829. At the same time, the connecting plate 828 and the first spray pipe 829 are detachably connected by bolts, which can further fine-tune the angle of the first spray pipe 829 to perfectly fit the corner of the T-shaped component and the contour of the concave grooves on both sides, ensuring that the multiple sets of first nozzles 8210 on the arc-shaped first spray pipe 829 can fully cover the dead corner area and achieve spraying without omission.

[0050] Finally, curing water is introduced into the first spray pipe 829 through the first connector 8211. The curing water is sprayed out through multiple sets of evenly distributed first nozzles 8210 to continuously and evenly spray and cure the dead corner areas of the component.

[0051] In addition, while the dead-angle spraying mechanism 820 is working, the top surface spraying mechanism 830 and the side spraying mechanism 840 are simultaneously activated to achieve coordinated curing of the entire surface of the component. The second spray pipe 831 at the bottom of the support frame 811 introduces curing water through the second connector 833, which is then evenly sprayed onto the top surface of the bridge precast component 300 via multiple sets of second nozzles 832, ensuring uniform curing of the top surface. The third spray pipes 841 on both sides of the support frame 811 introduce curing water through the third connector 843, which is then sprayed onto the two sides of the component via multiple sets of third nozzles 842.

[0052] When it is necessary to spray water to cure the bottom of the precast bridge component 300, the first hydraulic cylinder 130 in the bearing unit 100 is activated. Its telescopic end pushes the top plate 140 upward, thereby causing the precast bridge component 300 to move upward, creating a gap between the bottom of the component and the bearing platform 120. At this time, the side spraying mechanism 840 can be adjusted in position, and curing water is sprayed into the gap at the bottom of the component through the third nozzle 842, achieving comprehensive curing of the bottom of the component and preventing cracks from occurring due to inadequate curing.

[0053] Throughout the curing process, the X, Y, and Z axis drive system precisely moves the curing unit 800, the dual-station moving mechanism 810 adapts to the width of the component, the dead-angle spraying mechanism 820 specifically solves the problem of dead-angle curing, and the top, side and bottom spraying work together to achieve uniform spraying curing of the entire surface of the bridge precast component 300, effectively avoiding cracks in the concrete due to insufficient curing.

[0054] At the same time, each unit can make precise adjustments according to the component size and maintenance needs, avoiding waste of maintenance water, achieving the goal of energy-saving maintenance, and improving the practicality and service life of the equipment.

[0055] The embodiments of this specific implementation have been described above. However, this embodiment is not limited to the specific implementation described above. The specific implementation described above is merely illustrative and not restrictive. Those skilled in the art can make many other forms based on the guidance of this embodiment, all of which are within the protection scope of this embodiment.
