Through the setting of side plates, the rollers and rotating rollers arranged on the side plates are used to support the side plates, and then the side plates can be driven to move. By using the fixing grooves opened on the side plates and the rotating rods arranged in the fixing grooves, and at the same time using the first maintenance film rolls arranged on the rotating rods, the side plates can drive the first maintenance film rolls to move, and the maintenance film on the first maintenance film rolls is bypassed under the rotating rollers and rollers. When the side plates are pushed, the rotation of the rotating rollers on the maintenance film can lay the maintenance film on the road.
[0004] In view of the above and related existing technologies, the inventor believes that the following defects often exist: Currently, when maintaining concrete, it is necessary to perform film covering treatment on the surface of the concrete, but the existing concrete film covering maintenance devices may not be able to make the film more closely attached to the surface of the concrete. In view of the above defects, the concrete maintenance device is improved, so that when the staff covers the film on the surface of the concrete, the surface of the film is more closely attached to the surface of the concrete, thereby improving the film covering effect and the maintenance effect of the concrete. Summary of the Utility Model
[0005] The technical problem to be solved by the utility model is that there is a defect in the prior art that the existing concrete film covering maintenance device may not be able to make the film more closely attached to the surface of the concrete.

[0021] Now, the present utility model will be further described in detail with reference to the attached drawings and preferred embodiments. These drawings are all simplified schematic diagrams, only illustrating the basic structure of the present utility model in a schematic manner, so they only show the components related to the present utility model.
[0022] Refer to Figure 1 - Figure 3As shown, the utility model provides a technical solution: a concrete maintenance device, including a connecting base plate 1, the inner cavity of the connecting base plate 1 is connected to a limiting bolt 2 through a thread, force handles 3 are installed on both sides of the connecting base plate 1 through the limiting bolts 2, the inner cavity of the force handle 3 is fixedly connected to a connecting frame 4, the surface of the connecting base plate 1 is fixedly connected to an adjusting shell 5, one end of the adjusting shell 5 close to each other is installed with a bonding roller 6, the inner cavity of the adjusting shell 5 is slidably connected to a hollow block 7, the interior of the hollow block 7 is provided with a sliding hole 8, one end of the hollow block 7 is fixedly connected to a connecting plate 9, the inner cavity of the connecting plate 9 is provided with a circular hole 10, and the inner diameter of the circular hole 10 is the same as that of the bonding roller 6. The two sides are rotatably connected. When the staff needs to make the surface of the film fit more closely to the concrete surface, the staff continuously presses down the slide hole 8 through the rebound force of the first spring 12 to move it downward, so that the slide hole 8 has space to stretch back and forth. At the same time, the slide hole 8 drives the surface of the guide block 14 to slide in the inner cavity of the guide groove 13. With the displacement of the slide hole 8, the slide hole 8 drives the connecting plate 9 to move downward, so that the surface of the bonding roller 6 fits tightly to the surface of the concrete. Through the arrangement of the above structure, when the staff coats the concrete surface with a film, the surface of the film can fit more closely to the surface of the concrete, thereby improving the coating effect and the maintenance effect of the concrete.
[0023] Reference Figure 3 As shown, in this embodiment: the inner cavity of the adjusting shell 5 is fixedly connected with a limit rod 11, and the surface of the limit rod 11 is slidably connected with the inner diameter of the sliding hole 8. Through the setting of the limit rod 11, when the sliding hole 8 is displaced, the sliding hole 8 is prevented from being separated from the inner cavity of the adjusting shell 5 to affect the coordination between the structures.
[0024] Reference Figure 3 As shown, in the present embodiment: the inner cavity of the adjusting shell 5 is fixedly connected with the first spring 12, and the bottom end of the first spring 12 is fixedly connected with the hollow block 7. Through the setting of the first spring 12, the rebound force of the first spring 12 continuously pushes the sliding hole 8 to move downward, and at the same time makes the sliding hole 8 have a certain rebound effect, so that the applicability of the bonding roller 6 is improved.
[0025] Reference Figure 3 As shown, in the present embodiment: a guide groove 13 is provided at one end of the adjusting shell 5, and a guide block 14 is slidably connected to the inner cavity of the guide groove 13, and the end of the guide block 14 close to the hollow block 7 is fixedly connected to the hollow block 7. By setting the guide groove 13 and the guide block 14, the sliding hole 8 maintains a directional displacement when it is displaced, preventing the sliding hole 8 from being offset when moving, thereby affecting the coating effect of the bonding roller 6.
[0026] Reference Figure 1 , Figure 2 and Figure 4As shown, in this implementation: A fixing block 15 is fixedly connected to the top end of the connecting base plate 1. A film covering roller 16 is installed at one end of the fixing block 15 close to each other. One end of the fixing block 15 is fixedly connected to a hollow column 17. A pull rod 18 is slidably connected to the inner cavity of the hollow column 17. One end of the pull rod 18 is fixedly connected to a connecting ring 19. One end of the connecting ring 19 is fixedly connected to a hollow circular plate 20. A rotating rod 21 is rotatably connected to the inner cavity of the hollow circular plate 20. When the staff needs to replace the film covering roller 16, the staff pulls the pull rod 18, causing the pull rod 18 to drive the connecting ring 19 to displace. At the same time, it drives the surface of the slider 24 to slide in the inner cavity of the chute 23, causing the connecting ring 19 to squeeze the second spring 22 to store energy. As the connecting ring 19 displaces, the connecting ring 19 drives the hollow circular plate 20 and the rotating rod 21 to gradually separate from both ends of the film covering roller 16. At this time, the staff can disassemble and replace the film covering roller 16. Through the setting of the above structure, it is convenient for the staff to replace the film covering roller 16 conveniently, preventing the subsequent film covering process from being affected after the film covering roller 16 is used up.
[0027] Refer to Figure 4 As shown, in this implementation: A second spring 22 is fixedly connected to the inner cavity of the fixing block 15. One end of the second spring 22 close to the connecting ring 19 is fixedly connected to the connecting ring 19. Through the setting of the second spring 22, the hollow circular plate 20 is convenient to quickly reset, facilitating the staff to install both ends of the film covering roller 16.
[0028] Refer to Figure 4 As shown, in this implementation: A chute 23 is opened inside the hollow column 17. A slider 24 is slidably connected to the inner cavity of the chute 23. One end of the slider 24 close to the connecting ring 19 is fixedly connected to the connecting ring 19. Through the setting of the chute 23 and the slider 24, the connecting ring 19 maintains a directional displacement when displacing, preventing the connecting ring 19 from shifting and affecting the installation of the hollow circular plate 20 and the film covering roller 16.
[0029] Working principle: When the staff needs to make the surface of the film fit more closely to the concrete surface, the staff continuously presses down the sliding hole 8 through the resilience of the first spring 12 to move downward, so that the sliding hole 8 has space for back-and-forth stretching. At the same time, the surface of the sliding hole 8 drives the guide block 14 to slide in the inner cavity of the guide groove 13. As the sliding hole 8 moves, the sliding hole 8 drives the connecting plate 9 to move downward, so that the surface of the fitting roller 6 closely fits the surface of the concrete. Through the setting of the above structure, when the staff laminates the concrete surface, the surface of the film fits more closely to the concrete surface, thereby improving the laminating effect and enhancing the maintenance effect of the concrete. When the staff needs to replace the laminating roller 16, the staff pulls the pull rod 18, so that the pull rod 18 drives the connecting ring 19 to move, and at the same time drives the surface of the slider 24 to slide in the inner cavity of the chute 23, so that the connecting ring 19 compresses the second spring 22 to store energy. As the connecting ring 19 moves, the connecting ring 19 drives the hollow circular plate 20 and the rotating rod 21 to gradually disengage from both ends of the laminating roller 16. At this time, the staff can disassemble and replace the laminating roller 16. Through the setting of the above structure, it is convenient for the staff to replace the laminating roller 16 conveniently, preventing the laminating roller 16 from affecting subsequent laminating treatment after being used up.
