Description

Technical Field

[0001] The invention relates to the technical field of concrete curing, in particular to a large-span arched concrete curing device. Background Art

[0002] Prefabricated concrete parts are produced in factories. Compared with traditional cast-in-place concrete, which requires on-site molding, pouring and curing, the production process of prefabricated parts is more efficient and environmentally friendly, and can effectively reduce on-site construction noise pollution. With the development of building industrialization, the production scale of large-span arched concrete prefabricated parts has continued to expand, and higher requirements have been placed on the curing quality and efficiency of prefabricated parts. For prefabricated concrete parts, some devices use spray pipes for curing. Spray pipes are usually designed according to the layout of planes or simple curved surfaces. When applied to arched prefabricated parts, the spray range cannot fully cover the surface of the prefabricated parts, resulting in over-curing in some areas and insufficient curing in some areas, affecting the uniformity of the overall quality of the prefabricated parts. In terms of curing efficiency, traditional curing methods often require a lot of manpower and time.

It includes a three-way joint, a three-pronged rotating nozzle, a spray hose, an L joint, a water supply hose, a control console, a pressure pump and a mobile water tank; the bottom surface of the mobile water tank is provided with multiple rollers and is placed on the ground; the water inlet of the pressure pump is connected to the mobile water tank, and the water outlet is connected to one end of the water supply hose; multiple spray hoses are connected to each other into a mesh using three-way joints and L joints, and connected to the other end of the water supply hose; multiple three-pronged rotating nozzles are installed at intervals on multiple spray hoses, thereby forming a spray network; the control console is electrically connected to the pressure pump. This patent realizes water spray maintenance on the surface of the arched concrete by laying a hose on the arched surface, and the hose is provided with a nozzle, and water is pumped into the nozzle by a water pump and sprayed out.

[0004] This prior art realizes water spraying maintenance on the surface of the arched concrete by laying a hose on the surface of the arched concrete, on which a nozzle is provided, and by using a water pump to draw water into the nozzle and spray it out. However, with the continuous development of modern construction technology, the application of large-span arched concrete structures is becoming more and more extensive, and their maintenance requirements are becoming increasingly diversified. Although the traditional water spraying maintenance method has a good surface maintenance effect on the arched concrete, it has significant limitations: it cannot effectively cover the inner part of the arched concrete. For large-span arched concrete structures, the maintenance of the inner part is also crucial, because the maintenance condition of the inner concrete directly affects the stability and durability of the entire structure. If the inner concrete is not adequately maintained, problems such as cracking and reduced strength will also occur, which will pose a threat to the safety of the entire structure.

[0016] The beneficial effects of the present invention compared with the prior art are:

[0017] 1. The present invention provides a water spray assembly on the kit and the slide, and the water spray assembly is equipped with a movable box that can reciprocate thereon. When the movable box moves along the guide to the bottom of the guide, the curing device can automatically adjust its size responsively to ensure that the curing device is sleeved on the outside of the arch structure. At this time, the nozzle sprays water to the outside of the arched concrete to achieve a comprehensive and uniform curing effect. When the movable box moves to the top of the guide, the curing device can also be quickly and accurately adjusted to the inside of the arched structure, and the nozzle then sprays water to the inside of the arched concrete to ensure that both the inside and outside of the arched structure can be fully cured. This design of automatically adjusting the size not only greatly improves the curing efficiency, but also significantly reduces the complexity and cost of manual operation, providing a more convenient and efficient solution for the curing of concrete in arched structures.

[0018] 2. In order to further improve the maintenance effect, the present invention innovatively sets a rotatable nozzle at the bottom of the mobile box. The nozzle is equipped with an impeller. When the high-pressure water flow enters the nozzle, it drives the impeller to rotate, thereby driving the entire nozzle to rotate. The rotation of the nozzle produces a significant centrifugal force effect, which enables the water flow to be thrown farther when it is sprayed, thereby greatly expanding the range of water spraying. This design improves the coverage of the water flow and further improves the uniformity and comprehensiveness of the maintenance.

[0019] 3. The water spray assembly on the slide of the present application can move flexibly along its arc direction. When the slide is retracted into the kit, the kit will push a water spray assembly on the slide to move. Since a spring is cleverly arranged between two adjacent water spray assemblies, when one of the water spray assemblies moves, the remaining water spray assemblies will also move synchronously through the elastic action of the spring. This synchronous movement mechanism ensures that the water spray assemblies can maintain a consistent arrangement and spacing during the process of the slide being retracted into and removed from the kit, thereby avoiding the problem of affecting the size adjustment of the maintenance device due to the position interference of the water spray assemblies on the slide.

DETAILED DESCRIPTION

[0031] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] Reference Figure 1-Figure 9 As shown, the present invention provides a large-span arched concrete curing device, including a kit 1 and a slide 2, the slide 2 can slide in the kit 1, the cross-sections of the kit 1 and the slide 2 are both arc-shaped, a plurality of water spray assemblies 7 are evenly arranged on the kit 1 along its arc direction, and a plurality of water spray assemblies 7 are slidably arranged on the slide 2 along its arc direction, the water spray assembly 7 includes a guide member 71, a moving box 72 that can reciprocate along the water spray assembly 7 is arranged on the guide member 71, and a nozzle 73 is also rotatably arranged on the moving box 72. When the moving box 72 moves to the bottom of the guide member 71, the nozzle 73 can spray water to the outside of the arched concrete, and when the moving box 72 moves to the top of the guide member 71, the nozzle 73 can spray water to the inside of the arched concrete.

[0033] The guide member 71 is arranged in a U shape, and the two sides of the guide member 71 are also provided with a U-shaped guide groove 711, and the inner side of the mobile box 72 is rotated and provided with a roller 721 that cooperates with the guide groove 711. The guide member 71 is arranged in a U shape, and this design not only provides structural stability, but also provides a clear path for the sliding of the mobile box 72. The two sides of the U shape are provided with guide grooves 711, and these guide grooves 711 play the role of guiding the movement of the mobile box 72. The mobile box 72 is also provided with a rotating drive member that can drive the roller 721 to rotate in the guide groove 711. The design of the roller 721 reduces the friction resistance when the mobile box 72 moves in the guide groove 711, making the movement smoother. At the same time, the close cooperation of the roller 721 and the guide groove 711 also ensures the stability of the mobile box 72 during movement. When the rotating drive member drives the roller 721 to rotate, the mobile box 72 can move back and forth on the guide member 71.

[0034] When the moving box 72 moves along the guide member 71 to the bottom of the guide member 71, the maintenance device can automatically adjust its size responsively to ensure that the maintenance device is mounted on the outside of the arch structure. At this time, the nozzle 73 sprays water to the outside of the arched concrete to achieve a comprehensive and uniform maintenance effect. When the moving box 72 moves to the top of the guide member 71, the maintenance device can also be quickly and accurately adjusted to the inside of the arched structure, and the nozzle 73 then sprays water to the inside of the arched concrete to ensure that both the inside and outside of the arched structure can be fully maintained. This design of automatically adjusting the size not only greatly improves the maintenance efficiency, but also significantly reduces the complexity and cost of manual operation, providing a more convenient and efficient solution for the concrete maintenance of the arched structure.

[0035] The top of the nozzle 73 is rotatably arranged in the moving box 72 and is connected to an impeller 731, and a plurality of water spray holes for spraying water are arranged at the bottom of the nozzle 73. When the impeller 731 rotates under the action of the high-pressure water flow, the impeller 731 drives the nozzle 73 to rotate.

[0036] When the high-pressure water flows into the nozzle 73, it drives the impeller 731 to rotate, thereby driving the entire nozzle 73 to rotate. The rotation of the nozzle 73 produces a significant centrifugal force effect, which enables the water flow to be thrown farther when it is sprayed, thereby greatly expanding the range of water spraying. This design increases the coverage of the water flow and further improves the uniformity and comprehensiveness of maintenance.

[0037] A slide groove 21 is provided at the center position of the inner and outer sides of the slide 2 along its arc direction, and a slider 23 is also slidably arranged in the slide groove 21, and the slider 23 is connected to the water spray assembly 7 on the slide 2, and a spring 22 is also arranged between adjacent sliders 23. When the slide 2 is retracted into the kit 1, the water spray assembly 7 on the slide 2 can move.

[0038] When one of the water spray assemblies 7 moves, the other water spray assemblies 7 will also move synchronously due to the elastic action of the spring 22. This synchronous movement mechanism ensures that the water spray assemblies 7 can maintain a consistent arrangement and spacing during the process of the slide 2 being retracted into and moved out of the kit 1, thereby avoiding the problem of affecting the size adjustment of the maintenance device due to the position interference of the water spray assemblies 7 on the slide 2.

[0039] The bottom of the set 1 and the slide 2 are both rotatably provided with a support plate 3, and a telescopic plate 31 that can move up and down is also provided in the support plate 3, and a moving trolley 4 that can move automatically is also fixed to the bottom of the telescopic plate 31. The moving trolley 4 is also provided with a hydraulic assembly 5 that can pump hydraulic oil into the set 1 and the support plate 3, and the hydraulic assembly 5 is used to move the slide 2 in the set 1 and the telescopic plate 31 in the support plate 3.

[0040] When it is necessary to maintain the large-span arched concrete, the entire device is first moved to the working position by moving the trolley 4. Then, the hydraulic assembly 5 is started to drive the slide 2 to slide in the kit 1 by pumping hydraulic oil to adjust the relative position between the kit 1 and the slide 2 to adapt to the inside or outside of the arched concrete. By controlling the hydraulic assembly 5, the telescopic plate 31 can also be driven to move up and down in the support plate 3 to adjust the height of the kit 1 and the slide 2 to adapt to arched concrete structures of different heights.

[0041] The hydraulic assembly 5 includes a hydraulic pump and an oil tank arranged inside the mobile vehicle 4, and the hydraulic pump and the oil tank are connected by a pipeline. The oil outlet of the hydraulic pump is connected to a hydraulic hose 51, and the hydraulic hose 51 can be connected to the support plate 3. The hydraulic hose 51 is also connected to the kit 1. The hydraulic hose 51 is also provided with a solenoid valve 52 that can control the hydraulic oil to enter the kit 1 and the support plate 3 respectively.

[0042] When it is necessary to drive the slide 2 in the kit 1 to move or adjust the height of the telescopic plate 31, the hydraulic pump is first started. The hydraulic pump extracts hydraulic oil from the oil tank and delivers it to the solenoid valve 52 through the hydraulic hose 51. The solenoid valve 52 adjusts its opening and closing states to deliver the hydraulic oil to the kit 1 and the support plate 3 respectively, thereby driving the slide 2 to slide in the kit 1 or the telescopic plate 31 to move up and down in the support plate 3. By controlling the opening and closing time of the solenoid valve 52 and the flow rate of the hydraulic oil, precise control of the kit 1 and the support plate 3 can be achieved, thereby achieving adjustment of the entire device.

[0043] The outside of the mobile trolley 4 is also provided with a water supply assembly 6 capable of pumping water into the water spray assembly 7 and spraying water out of the spray head 73. The water supply assembly 6 also includes a water tank 61 fixed on the mobile trolley 4 for storing water, and the water supply assembly 6 also includes a tube collector 62 arranged on the water tank 61, the tube collector 62 is connected to a second connecting hose 622, the second connecting hose 622 is connected to the mobile box 72, the tube collector 62 is also connected to a first connecting hose 621, and a water pump 623 is also provided in the water tank 61, and the water pump 623 is connected to the first connecting hose 621. A valve for water inlet is also connected to the water tank 61.

[0044] When the arched concrete needs to be maintained, first ensure that there is enough water in the water tank 61. Then start the water pump 623, and the water pump 623 starts to pump water from the water tank 61. The pumped water is transported to the tube collector 62 through the first connecting hose 621, and then, under the arrangement and guidance of the tube collector 62, it is transported to the water spray assembly 7 in the mobile box 72 through the second connecting hose 622. The nozzle 73 in the water spray assembly 7 starts to rotate under the action of the high-pressure water flow, and sprays water evenly on the arched concrete. The water supply assembly 6, as a part of the mobile trolley 4, can move with the mobile trolley 4. In this way, no matter where the mobile trolley 4 moves to, the water supply assembly 6 can provide a stable water flow for the water spray assembly 7 to ensure the continuity and efficiency of the maintenance operation.
