Description

Technical Field

[0001] This invention relates to the field of highway concrete curing technology, specifically a device for curing bridge deck concrete in highway engineering bridge construction. Background Technology

[0002] Highway engineering refers to the surveying, measurement, design, construction, maintenance, and management of highway structures. Highway engineering structures include: roadbed, pavement, bridges, culverts, tunnels, drainage systems, safety protection facilities, greening and traffic monitoring facilities, as well as buildings, workshops and other service facilities used for construction, maintenance and monitoring. During the construction of highway bridges, it is necessary to maintain the concrete of the bridge deck.

[0003] Currently, the common practice is to cover the concrete surface with a thin film to reduce the loss of moisture and heat from the concrete. However, when covering load-bearing concrete columns in highway engineering, scaffolding needs to be erected manually so that workers can cover and cure the entire concrete column. During the covering and curing process, workers need to climb the scaffolding, which poses certain work risks and causes inconvenience to the curing of highway concrete. Therefore, in view of the above situation, there is an urgent need to develop a concrete curing device for bridge deck construction in highway engineering to overcome the shortcomings in current practical applications. Summary of the Invention

[0004] The purpose of this invention is to provide a device for curing concrete on bridge decks during highway engineering construction, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A concrete curing device for highway bridge construction includes:

[0007] Support plate;

[0008] A film-coating mechanism, which is connected to the support plate, is used to achieve rotational film coating of the concrete column;

[0009] A take-up and positioning mechanism is connected to the support plate and is used to cooperate with the support plate to achieve the flipping and retraction of the film coating mechanism;

[0010] The coating mechanism includes:

[0011] Support assembly, the support assembly being disposed on the outside of the support plate;

[0012] A lifting and rotating assembly is fixedly connected to the support plate and connected to the support assembly, and is used to drive the support assembly to lift and rotate.

[0013] A film covering assembly, which is connected to the support assembly, is used to cooperate with the movement of the support assembly to achieve automatic all-round film covering of the concrete column;

[0014] A cutting assembly, connected to the film-coating assembly, is used to cut the film.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] During operation, the deployment and positioning mechanism is connected to the engineering vehicle. As the deployment and positioning mechanism drives the support plate to rotate, it is also attracted to the vehicle body. The support plate unfolds the film covering mechanism, and the lifting and rotating assembly drives the support assembly to rise and fall, so that the support assembly is fitted onto the outside of the concrete column. After the film covering assembly is adjusted, the lifting and rotating assembly drives the support assembly to rise, fall, and rotate simultaneously. The support assembly drives the film covering assembly to rotate around the concrete column and moves it upward, so that the film can be evenly wrapped around the outside of the concrete column, thus achieving the curing of the concrete column. The cutting component then cuts the film near the end of the concrete to be cured, and the device continues to cure the remaining concrete column. Compared with the prior art, when covering load-bearing concrete columns in highway engineering, this application requires the manual construction of scaffolding so that workers can cover the entire concrete column. During the process of covering the concrete column, workers need to climb the scaffolding, which poses certain work risks and brings inconvenience to the maintenance of highway concrete. By setting up a film covering mechanism, in conjunction with a take-up and positioning mechanism, the equipment can be flexibly connected to the engineering vehicle, improving the convenience of the equipment during use. It can also automatically cover the concrete column from all directions, effectively reducing the difficulty of film covering and greatly improving the maintenance efficiency and effect.

The support plate 1 unfolds the film covering mechanism 3. The lifting and rotating component 4 drives the support component 5 to lift and lower, so that the support component 5 is fitted on the outside of the concrete column. After the film covering component 6 is adjusted, the lifting and rotating component 4 drives the support component 5 to lift and rotate, and the two processes are carried out simultaneously. On the one hand, the support component 5 drives the film covering component 6 to rotate around the concrete column, and on the other hand, it drives the film covering component 6 to move upward, so that the film can be evenly wrapped around the outside of the concrete column, thereby achieving the curing of the concrete column. Subsequently, the cutting component 7 cuts the film near the end of the concrete to be cured, and the device continues to cure the remaining concrete column. Compared with the prior art, when covering the load-bearing concrete columns in highway engineering, it is necessary to manually build scaffolding so that workers can cover the entire concrete column. During the process of covering the concrete column, workers need to climb the scaffolding, which poses certain work risks and brings inconvenience to the maintenance of highway concrete. By setting up the film covering mechanism 2, in conjunction with the retraction and positioning mechanism 3, the equipment can be flexibly connected to the engineering vehicle, improving the convenience of the equipment during use, and can automatically cover the concrete column from all directions, effectively reducing the difficulty of film covering and greatly improving the maintenance efficiency and effect.

The transmission rod 10, in conjunction with a limiting block, drives a driven rod 13 to rotate, which in turn drives a first gear 15 to rotate. During the rotation of the threaded rod 9, the lifting plate 12 is raised and lowered, which in turn drives a support assembly 5 to rise and fall. During the rotation of the first gear 15, in conjunction with the support assembly 5, the film covering assembly 6 rotates around the concrete column. Combined with the raising and lowering of the lifting plate 12, this allows the film to be evenly wrapped around the outside of the concrete column, achieving automatic film covering, effectively reducing the difficulty of film covering and significantly improving curing efficiency and effectiveness. Through the installation of the film covering assembly 6, a movable frame 25, and a first elastic element 27... The support roller 26 provides stable support for the film, effectively tensioning it and improving the coating effect. The fixed component 22 facilitates switching of the film roll 23 and ensures its stability during use, guaranteeing the coating effect. The retraction and positioning mechanism 2, when the third telescopic component 40 drives the movable plate 39, moves the rack 42, which, in conjunction with the third gear 47, rotates the support rod 41. The support rod 41 then rotates the support plate 1, enabling the retraction and unfolding of the coating mechanism 3. Simultaneously, the movable plate 39, via the slide rod 46, moves the piston inside the piston tube 43, creating negative pressure inside the suction cup 44. The suction cup 44 then connects with the engineering vehicle, securing the equipment and ensuring its stability and flexibility during use. The retraction and unfolding of the coating mechanism 3 facilitates equipment maintenance and reduces its height during storage, improving ease of storage and transportation and enhancing usability.

These will not affect the effectiveness of the implementation of the present invention or the practicality of the patent.
