[0001] The utility model belongs to the field of film covering devices, in particular to a bridge maintenance film covering device. Background Art

[0002] Concrete needs to be poured during bridge construction. After the concrete is poured, it can gradually solidify and harden mainly because of the solidification of cement water. The hydration requires appropriate temperature and humidity conditions. Therefore, in order to ensure that the concrete has suitable hardening conditions and its strength continues to increase, the concrete must be cured. In order to obtain good concrete quality, and in the concrete molding process, in order to reduce the volatilization of water and keep warm, a layer of film needs to be covered. Usually, the film is covered manually, which is not only difficult to work, but also not accurate enough and not convenient to compact the curing film. Utility Model Content

[0023] The present invention is further described below through specific embodiments in conjunction with the accompanying drawings, but the present invention is not limited thereto. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

[0024] Example 1

[0025] A bridge maintenance coating device described in this embodiment, such as Figure 1 and Figure 5 As shown, it comprises a horizontally arranged fixing plate 1, and two telescopic rods 3 are vertically arranged at the bottom of the fixing plate 1 to facilitate height adjustment;

[0026] The front side wall of the telescopic rod 3 is provided with a coating component for coating the bridge deck, and the telescopic rod 3 is provided with a moving component for compacting the film. A push rod 2 for easy pushing is provided on the top of the fixed plate 1, so as to facilitate coating the bridge deck during the movement and compact the film during the movement, thereby improving the coating effect and effectively reducing the work difficulty of the construction personnel.

[0027] The telescopic rod 3 includes an outer tube 3.1, which is vertically fixed to the bottom of the fixed plate 1, and an inner tube 3.2 is installed inside the outer tube 3.1 to slide up and down with the inner tube 3.2. A first spring 12 is arranged in the outer tube 3.1 between the inner tube 3.2 and the fixed plate 1, and two ends of the first spring 12 are respectively fixed to the bottom of the fixed plate 1 and the top of the inner tube 3.2, which not only improves its applicability, but also makes it more comfortable for operators to use.

[0028] The moving component is a first roller 8, and the first roller 8 is installed at the bottom of the inner tube 3.2, which is convenient for movement and reduces the difficulty of workers' work, and is also convenient for compacting the bridge deck during movement, so that the coating efficiency is improved;

[0029] The moving assembly may also be a roller or a row of third rollers, which can also achieve better and more stable compaction effect on the coating while completing the movement.

[0030] Example 2

[0031] This embodiment further illustrates the technology. Figure 1 , Figure 2 and Figure 3As shown, the coating assembly includes a roller 9, and the length between the two first rollers 8 is equal to or less than the length of the roller 9, the roller 9 is fixed to the front side wall of the inner tube 3.2 through a rack 10, and the roller 9 and the rack 10 are free to rotate forward and backward, the rack 10 and the inner tube 3.2 are fixed by a connecting block, and the front side wall of the outer tube 3.1 is provided with a through groove for the connecting block to pass through, the roller 9 is used to wind the curing film, and when in use, the film is transferred to the bridge deck by rotating the roller 9, and then the film is pressed and pushed forward by the first roller 8 during the movement, and the film is pulled by the first roller 8 during the pushing process, thereby driving the roller 9 to rotate and transfer the film to the bridge deck, thereby completing the laying and compacting of the film simultaneously during the movement.

[0032] Example 3

[0033] This embodiment further illustrates the technology. Figure 1 and Figure 2 As shown, the side wall of the outer tube 3.1 is provided with an auxiliary component for increasing stability, so as to improve the stability during the mobile lamination, thereby improving the compaction effect to a certain extent and making the work efficiency higher;

[0034] The auxiliary component includes an outwardly inclined support rod 6, the top of which is connected to the side wall of the outer tube 3.1, and a second roller 7 is installed at the bottom of the support rod 6, with a gap between the second roller 7 and the ground. In a natural state, the distance between the second roller 7 and the ground is smaller than the distance that the inner tube 3.2 slides in the outer tube 3.1, so that the inner tube 3.2 can be driven to shrink in the outer tube 3.1 by pressing the fixing plate 1, so that the second roller 7 contacts the ground, thereby increasing the contact point with the ground and improving the friction with the ground and the film, so that the film is less likely to be displaced during the movement and has a higher fit with the bridge deck.

[0035] Example 4

[0036] This embodiment further illustrates the technology. Figure 1 , Figure 2 and Figure 5 As shown, a fixed block 5 is arranged between the top end of the support rod 6 and the outer tube 3.1, and a slide groove is vertically opened on the fixed block 5, and the top end of the support rod 6 is displaced in the slide groove to slide up and down with it, and a second spring 13 is arranged on the support rod 6 and the top of the slide groove, and the two ends of the second spring 13 are respectively fixed to the support rod 6 and the top of the slide groove, so as to prevent the second roller 7 from squeezing the film too much and causing excessive friction between the second roller 7 and the film, thereby preventing the second roller 7 from causing the film to rupture during the movement.

[0037] The push rod 2 is hinged to the top of the fixing plate 1 to swing forward and backward, so that different swing angles can be adjusted according to different operators, making the use of the operator more comfortable.

[0038] Example 5

[0039] This embodiment further illustrates the technology. Figure 1 and Figure 3 As shown, a limit rod 4 is vertically fixed at the bottom of the fixed plate 1 located on the front side of the outer tube 3.1. The bottom end of the limit rod 4 is a hook-shaped structure. In a natural state, the bottom end of the limit rod 4 is tightly fitted with the connecting rod 11, which is convenient for preventing the roller 9 from rotating and causing pollution by the film wrapped thereon falling off. It is also convenient for stopping the laying of the film during the coating process so that the bottom end of the limit rod 4 fits with the connecting rod 11 to stop the rotation of the roller 9.

[0040] Example 6

[0041] This embodiment further illustrates the technology. The first roller 8 is a universal wheel, and the second roller 7 is a directional wheel, which is convenient for adjusting the moving direction during transfer and lamination. It is also convenient to avoid fixing the moving direction through the second roller 7 during lamination, so that the lamination direction is accurate.

[0042] Working principle: first wind the required film on the roller 9, then move the hand-held push rod 2 to the starting point of the film coating through the first roller 8, after watering the bridge deck, manually pull out a part of the film on the roller 9, and press this part of the film on the bottom of the first roller 8, and then press down the fixed plate 1 to make the inner tube 3.2 shrink into the outer tube 3.1, until the bottom end of the limit rod 4 falls off from the connecting rod 11, and the second roller 7 contacts the ground or the film, and then push the push rod 2 forward. When it is necessary to stop the film coating, release the downward pressure on the fixed plate 1 so that the bottom end of the limit rod 4 is tightly fitted with the connecting rod 11.
