Abstract
Description
Technical Field
[0001] This application relates to the field of road construction, and in particular to a membrane covering device for concrete road construction. Background Technology
[0002] After the concrete pavement construction is completed, a protective film needs to be applied to ensure the quality of the concrete surface layer. This film protection reduces the evaporation of moisture from the concrete, preventing surface cracking due to rapid moisture loss. It also helps prevent damage to the concrete surface from external debris and vehicles, ensuring the concrete hardens properly during the curing period.
[0003] Currently, the mulching of concrete pavements is generally carried out manually. The specific method involves workers rolling the film onto rollers, then carrying the rollers to the concrete pavement, and finally unfolding the film to cover the concrete surface. However, concrete pavements are usually quite long, and the process of workers carrying the mulching rollers is time-consuming and labor-intensive. Moreover, repeated carrying and mulching operations on long pavements not only increase the labor intensity of workers but also significantly affect the overall mulching efficiency, leading to delays in the construction schedule. In addition, during manual mulching, it is difficult to precisely control the flatness and tightness of the film, which may result in uneven film coverage, wrinkles, or gaps, affecting the curing effect of the concrete.
[0004] Regarding the aforementioned technologies, the inventors believe that existing concrete surface coating methods suffer from drawbacks such as being time-consuming, labor-intensive, and inefficient. Therefore, they have proposed a concrete pavement construction coating device to solve these problems. Utility Model Content
[0005] To address the problems of time-consuming, labor-intensive, and inefficient operation when applying a membrane to existing concrete surfaces, this application provides a concrete pavement construction membrane application device.
[0006] The concrete pavement construction film covering device provided in this application adopts the following technical solution:
[0007] A concrete pavement construction film covering device includes a main support frame, with secondary adjustment frames symmetrically and movably installed below the main support frame. The main support frame also has a spacing adjustment mechanism inside for adjusting the spacing between the two secondary adjustment frames. A support roller is rotatably installed on one side of the outer surface of each secondary adjustment frame. A fixing rod is fixedly installed in the middle of one side of the inner wall of each secondary adjustment frame. A film roller is sleeved on the outer surface of the fixing rod. A bearing support is fixedly installed on one side of the upper surface of each secondary adjustment frame. A movable support plate is rotatably installed inside the bearing support. A placement groove is formed at one end of the movable support plate, and a support rod is placed inside the placement groove. A connector is installed on one side of the hinge shaft of the movable support plate extending to the outside of the bearing support. A positioning mechanism is also provided on the outer surface of the bearing support for limiting and fixing the movable support plate.
[0008] Preferably, the spacing adjustment mechanism includes a connecting plate, which is fixedly installed on the other side of the auxiliary adjustment frame. A bidirectional lead screw is rotatably installed on both sides of the inner wall of the main support frame through the connecting plate. A handle is provided on one side of the bidirectional lead screw extending to the outside of the main support frame. Guide rods are fixedly installed on both sides of the inner wall of the main support frame near the bidirectional lead screw.
[0009] Preferably, the positioning mechanism includes a fixing plate, which is fixedly installed on the upper surface of the auxiliary adjusting frame near the bearing support. A limit screw is threadedly connected to the top of one side of the fixing plate, and one side of the limit screw abuts against the outer surface of the connector.
[0010] Preferably, the outer diameter of the support rod is smaller than the inner diameter of the placement groove, both sides of the support rod are located inside the placement groove, and the placement groove and the support rod are engaged with each other.
[0011] Preferably, a threaded hole is provided through one side of the connecting plate, and external threads with opposite thread patterns are provided on both sides of the outer surface of the bidirectional lead screw. The bidirectional lead screw and the threaded hole are adapted to each other. A through hole is provided through one side of the connecting plate near the threaded hole, and one side of the outer surface of the guide rod is located in the through hole.
[0012] In summary, this application includes the following beneficial technical effects:
[0013] By rotating the handle of the bidirectional lead screw, which engages with the threaded hole in the connecting plate, the two auxiliary adjusting frames move synchronously in opposite directions, thereby adjusting the spacing to match the road width. The film is placed on the film roller, and the starting end of the film is fixed to the support rod. After rotating the movable support plate to the appropriate position, it is secured by the limit screw. The pushing device rotates the support roller, causing the film roller to rotate, and the film smoothly unfolds to cover the road surface. Compared with existing technologies, this device effectively reduces the labor intensity of workers, significantly improves the film covering efficiency, and ensures the flatness and tightness of the film laying, thereby improving the curing effect of concrete.

[0018] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0019] This application discloses a membrane covering device for concrete pavement construction. (Refer to...) Figure 1-3 A concrete pavement construction film covering device includes a main support frame 1, with auxiliary adjustment frames 2 symmetrically and movably installed below the main support frame 1. The main support frame 1 also has a spacing adjustment mechanism inside, used to adjust the spacing between the two auxiliary adjustment frames 2. A support roller 3 is rotatably installed on one side of the outer surface of the auxiliary adjustment frame 2. A fixing rod 4 is fixedly installed in the middle of one side of the inner wall of the auxiliary adjustment frame 2. A film roller 5 is sleeved on the outer surface of the fixing rod 4. A bearing support 6 is fixedly installed on one side of the upper surface of the auxiliary adjustment frame 2. A movable support plate 7 is rotatably installed inside the bearing support 6. A placement groove 8 is opened on one side of the movable support plate 7. A support rod 9 is placed inside the placement groove 8. The outer diameter of the support rod 9 is smaller than the inner diameter of the placement groove 8. Both sides of the support rod 9 are located inside the placement groove 8. The placement groove 8 and the support rod 9 are interlocked. A connector 10 is installed on one side of the hinge shaft of the movable support plate 7 to the outside of the bearing support 6. A positioning mechanism is also provided on the outer surface of the bearing support 6, used to limit and fix the movable support plate 7.
[0020] The film roller 5 is mounted on the fixed rod 4 and can rotate freely, facilitating the unfolding of the film. The movable support plate 7 rotates flexibly through the bearing support 6, and the groove 8 cooperates with the support rod 9 to fix the starting end of the film. When the device is pushed, the support roller 3 rolls, driving the film roller 5 to rotate, and the film unfolds smoothly to cover the road surface.
[0021] Reference Figure 2The spacing adjustment mechanism includes a connecting plate 13, which is fixedly installed on the other side of the auxiliary adjustment frame 2. A bidirectional lead screw 14 is rotatably installed on both sides of the inner wall of the main support frame 1 through the connecting plate 13. A handle is provided on one side of the bidirectional lead screw 14 extending to the outside of the main support frame 1. Guide rods 15 are fixedly installed on both sides of the inner wall of the main support frame 1 near the bidirectional lead screw 14. A threaded hole is opened through one side of the connecting plate 13. External threads with opposite thread patterns are opened on both sides of the outer surface of the bidirectional lead screw 14. The bidirectional lead screw 14 and the threaded hole are compatible with each other. A through hole is opened through one side of the connecting plate 13 near the threaded hole. One side of the outer surface of the guide rod 15 is located in the through hole.
[0022] By rotating the bidirectional lead screw 14, the two auxiliary adjustment frames 2 move synchronously in opposite directions by utilizing the cooperation between the opposite threaded patterns on both sides of the screw and the threaded holes of the connecting plate 13, thereby adjusting the spacing to adapt to different road widths. The guide rod 15 plays a guiding and stabilizing role.
[0023] Reference Figure 3 The positioning mechanism includes a fixing plate 11, which is fixedly installed on the upper surface of the auxiliary adjusting frame 2 near the bearing support 6. A limit screw 12 is threadedly connected to the top of one side of the fixing plate 11, and one side of the limit screw 12 abuts against the outer surface of the connector 10.
[0024] The movable support plate 7 can rotate flexibly through the bearing support 6. After adjusting the placement angle of the movable support plate 7, tighten the limit screw 12 and press it against the connector 10 to fix the position of the movable support plate 7.
[0025] The implementation principle of the concrete pavement construction film covering device in this application embodiment is as follows: When the concrete pavement construction film covering device is working, the spacing adjustment mechanism plays a key role. By rotating the bidirectional lead screw 14, the two auxiliary adjustment frames 2 can move synchronously in opposite directions by utilizing the cooperation between the opposite thread patterns on both sides of the screw and the threaded holes of the connecting plate 13, thereby adjusting the spacing to adapt to pavements of different widths. The guide support rod 15 ensures the stability of the movement process.
[0026] The film roller 5 is mounted on the fixed rod 4 and can rotate freely, facilitating the unfolding of the film. The movable support plate 7 rotates flexibly via the bearing support 6, and the placement groove 8 cooperates with the support rod 9 to fix the starting end of the film. In the positioning mechanism, the limit screw 12, after being tightened, abuts against the connector 10, fixing the position of the movable support plate 7 and ensuring that the starting end of the film is firmly fixed. When the pushing device is activated, the support roller 3 rolls, driving the film roller 5 to rotate, and the film unfolds smoothly to cover the road surface, achieving efficient and stable film covering operation and effectively solving many problems associated with manual film covering.
