Description

Technical Field

[0001] This application relates to the field of concrete curing technology, specifically to a membrane covering device for concrete curing. Background Technology

[0002] Concrete curing involves artificially creating specific humidity and temperature conditions to allow freshly poured concrete to harden normally or accelerate its strength development. Concrete film curing is a method of maintaining concrete structures or components by covering them with a film. After the initial setting and before the final setting of the concrete, a curing film is laid using a film-covering device. This ensures a tight bond between the curing film and the concrete surface, promoting hydration and playing a significant role in crack prevention and moisture retention during the curing process.

[0003] The film rolls used for concrete curing come in different sizes, but the film covering device has a fixed structure and can only be installed on one size of film roll. Moreover, when a new film roll needs to be replaced during the film covering process, it is often necessary to disassemble the working mechanism of the film roll and then fix the working mechanism of the film roll after replacing it with a new film roll. The operation is relatively complicated and reduces work efficiency.

[0004] Therefore, it is desirable to provide a membrane covering device for concrete curing. Utility Model Content

[0005] This embodiment provides a film covering device for concrete curing, which solves the problems of fixed structure of the film covering device, which can only install film rolls of one size, and the complicated operation and reduced work efficiency when replacing the film rolls.

[0006] According to one aspect of this application, a concrete curing film covering device is provided, comprising an L-shaped plate one and an L-shaped plate two, wherein the L-shaped plate one and the L-shaped plate two are connected by a connecting plate one, and a T-shaped plate is fixed to one of the top ends of the L-shaped plate one and the L-shaped plate two that are close to each other. The concrete curing film covering device further includes:

[0007] A film roll mounting cylinder is symmetrically and rotatably connected to the side walls of L-shaped plate one and L-shaped plate two;

[0008] An adjustment structure is fixed to the top of the second L-shaped plate and connected to the T-shaped plate at the top of the first L-shaped plate.

[0009] Furthermore, the connecting plate is provided with mounting grooves in the L-shaped plate one and L-shaped plate two corresponding to the connecting plate one, and the two ends of the connecting plate one are slidably connected in the mounting grooves.

[0010] Furthermore, push rods are fixed to the top of the T-shaped plates at the top of both L-shaped plates one and two, and rollers are rotatably connected to the side walls of L-shaped plates one and two, with the rollers located at the bottom of the film roll mounting cylinder.

[0011] Furthermore, the adjustment structure includes a U-shaped frame, a motor, a threaded shaft, a moving plate, and a connecting plate II. The U-shaped frame is fixed to the top of the L-shaped plate II. A motor is fixed to the side wall of the U-shaped frame away from the T-shaped plate. The output end of the motor passes through the side wall of the U-shaped frame and is fixed to a threaded shaft. The other end of the threaded shaft is rotatably connected to the inner wall of the U-shaped frame that is away from the motor.

[0012] Furthermore, a movable plate is threadedly connected to the threaded shaft, with both ends of the movable plate extending outside the U-shaped frame. A second connecting plate is fixed to the side wall of the movable plate away from the motor at both ends, and the other end of the second connecting plate is fixed to the T-shaped plate at the top of the L-shaped plate.

[0013] Furthermore, an L-shaped scraper is fixed to the bottom of one end of the L-shaped plate one and the L-shaped plate two, the bottom of the L-shaped scraper is set in an arc shape, and a storage battery is fixed to the top of the L-shaped plate one.

[0014] The advantages of this application are:

[0015] 1. By symmetrically setting L-shaped plates one and two, which are slidably connected by connecting plate one, and the tops of L-shaped plates one and two are connected by an adjustment structure, film roll mounting cylinders are rotatably connected to the side walls of L-shaped plates one and two respectively. The motor in the adjustment structure drives the threaded axis to rotate in different directions, causing the moving plate to move left and right along the threaded axis, adjusting the distance between L-shaped plates one and two, and thus the distance between the film roll mounting cylinders, so that the film coating device can install film rolls of different sizes. When disassembling the used film roll, the film roll mounting cylinders on the side walls of L-shaped plates one and two are adjusted away from the end of the film roll by the adjustment structure, so that the film roll mounting cylinders are separated from one end of the film roll. When installing the film roll, the film roll mounting cylinders on the side walls of L-shaped plates one and two are moved closer to the film roll, so that the film roll mounting cylinders are locked at the end of the film roll. This makes operation convenient and improves work efficiency. Attached Figure Description

[0027] Please see Figure 1-3 As shown, a concrete curing film covering device includes an L-shaped plate 1 and an L-shaped plate 2, which are connected by a connecting plate 3. A T-shaped plate 6 is fixed to one of the top ends of both the L-shaped plate 1 and the L-shaped plate 2, which are close to each other. The concrete curing film covering device also includes:

[0028] Film roll mounting cylinder 4, the film roll mounting cylinder 4 is symmetrically and rotatably connected to the side walls of L-shaped plate 1 and L-shaped plate 2;

[0029] Adjustment structure 7 is fixed to the top of L-shaped plate 2 and connected to the T-shaped plate 6 at the top of L-shaped plate 1.

[0030] The connecting plate 3 has mounting grooves 11 in the L-shaped plate 1 and L-shaped plate 2, and the two ends of the connecting plate 3 are slidably connected in the mounting grooves 11.

[0031] Push rods 8 are fixed to the top of the T-shaped plates 6 at the top of L-shaped plate 1 and L-shaped plate 2. Rollers 5 are rotatably connected to the side walls of L-shaped plate 1 and L-shaped plate 2. The rollers 5 are located at the bottom of the film roll mounting cylinder 4.

[0032] The adjustment structure 7 includes a U-shaped frame 701, a motor 702, a threaded shaft 703, a moving plate 704, and a connecting plate 705. The U-shaped frame 701 is fixed to the top of the L-shaped plate 2. The motor 702 is fixed to the side wall of the U-shaped frame 701 away from the T-shaped plate 6. The output end of the motor 702 passes through the side wall of the U-shaped frame 701 and is fixed to the threaded shaft 703. The other end of the threaded shaft 703 is rotatably connected to the inner wall of the U-shaped frame 701 that is away from the motor 702.

[0033] A movable plate 704 is threadedly connected to the threaded shaft 703. Both ends of the movable plate 704 extend to the outside of the U-shaped frame 701. A connecting plate 705 is fixed to the side wall of the movable plate 704 away from the motor 702. The other end of the connecting plate 705 is fixed to the T-shaped plate 6 at the top of the L-shaped plate 1.

[0034] An L-shaped scraper 9 is fixed to the bottom of one end of the L-shaped plate 1 and the L-shaped plate 2. The bottom of the L-shaped scraper 9 is set in an arc shape.

[0035] Working principle and usage: All electrical components in this application are externally connected to a power supply and control device during use. First, by adjusting the motor 702 in structure 7, the threaded shaft 703 is rotated in different directions, causing the moving plate 704 to move left and right along the threaded shaft 703. This adjusts the distance between L-shaped plate 1 and L-shaped plate 2, allowing the film roll mounting cylinders 4 on the side walls of L-shaped plate 1 and L-shaped plate 2 to respectively engage with both ends of the film roll, enabling the film covering device to install film rolls of different sizes. After installation, the film covering device is pushed along the concrete by the push rod 8, covering the concrete surface with the film. During this pushing process, the L-shaped scraper 9 makes contact with the concrete... Surface contact, with the movement of the L-shaped scraper 9, allows the protective film to adhere to the concrete, ensuring a tight bond between the concrete curing film and the concrete surface, promoting the hydration effect of the concrete, and playing a significant role in crack prevention and moisture retention during the concrete curing process; when disassembling the film roll after use, the film roll installation cylinder 4 on the side walls of L-shaped plate 1 and L-shaped plate 2 is adjusted away from the end of the film roll by adjusting the structure 7, so that the film roll installation cylinder 4 is separated from one end of the film roll; when installing the film roll, the film roll installation cylinder 4 on the side walls of L-shaped plate 1 and L-shaped plate 2 is moved closer to the film roll, so that the film roll installation cylinder 4 is locked at the end of the film roll, making operation convenient and improving work efficiency.
