Abstract
Description
Technical Field
[0001] The utility model relates to the field of road film paving, in particular to a road construction film paving device. Background Art
[0002] The existing concrete road pavement maintenance is that after the initial setting and before the final setting of the concrete, the covering film of the film roll needs to be manually laid on the top of the concrete to prevent its surface from being exposed to the air, which is easily affected by sunlight and strong winds, causing surface cracks and extending the service life of the concrete. This method of laying the film after the initial setting and before the final setting of the concrete not only causes the moisture loss of the concrete pavement, but also requires watering and maintenance before laying the film. In addition, manual laying of the film also requires manual overlapping of the film rolls for pulling and laying, which is time-consuming, labor-intensive and extremely inefficient. Therefore, it is necessary to study a road construction film laying device to solve the above problems. Utility Model Content
[0003] In order to solve the above-mentioned problems, the utility model provides a road construction film laying device.
[0004] The utility model is realized through the following technical solutions:
[0005] A road construction film laying device includes a concrete road and side formwork on both sides thereof, a movable frame is provided on the upper part of the concrete road, the lower part of the movable frame is supported on the upper part of the side formwork by multiple support wheels on both sides, and multiple adjustable and movable film loaders are provided on the upper part of the movable frame in a front-to-back staggered manner. The film roll installed on the film loaders is moved by the movable frame to lay the wound covering film on the concrete road surface.
[0006] Further optionally, the mobile frame includes support frames on both sides, and the support frames are connected and fixed by multiple sliding rods.
[0007] Further optionally, the support wheel is transversely mounted on the lower side end of the support frame, and an annular retaining ring is provided on the outer side of the support wheel, and the annular retaining ring is located outside the side template.
[0008] Further optionally, the film loader includes a sliding sleeve slidably connected to the corresponding sliding rod, an L-shaped support rod is installed at the lower part of the sliding sleeve, and a rotatable film roll is installed at the side of the L-shaped support rod.
[0009] Further optionally, a locking screw for locking with the sliding rod is installed on the sliding sleeve, and a limit block for limiting the film roll from falling off is screwed on the outer end of the L-shaped support rod.
[0010] Further optionally, the covering films of the plurality of film rolls are laid on the concrete road surface in an overlapping manner at adjacent locations.
[0011] Further optionally, the covering membranes on both sides of the concrete road are located below the supporting wheels during laying.
[0012] Further optionally, a walking system is also included, which includes a battery box installed on the side of the support frame, the battery box is electrically connected to the upper controller, and the controller is electrically connected to the drive motor installed on the side of the support frame for driving the support wheel 4 to rotate.
[0013] Compared with the existing technology, the beneficial effect of the present invention is that the present invention can stagger the laying of covering film on the initially poured concrete road surface, and the covering film of multiple film rolls will be released and laid on the concrete road surface as the device moves forward, thereby realizing the rapid laying of the covering film. The entire laying process not only saves time and labor but also greatly improves the laying efficiency. At the same time, the laying is carried out before the concrete road solidifies, and the covering film has better adhesion to the relatively wet concrete road, which better prevents the loss of water in the concrete road and ensures the service life of the concrete road.

[0015] Figure 2 yes Figure 1 Schematic enlarged view of the local structure;
[0016] In the figure: concrete road 1, side formwork 2, support frame 3, support wheel 4, retaining ring 401, slide rod 5, sliding sleeve 6, L-shaped support rod 7, film roll 8, covering film 9, locking screw 10, drive motor 11, battery box 12, controller 13. DETAILED DESCRIPTION
[0017] The present invention is described in further detail below with reference to the accompanying drawings and specific embodiments:
[0018] like Figure 1 As shown, a road construction membrane laying device includes a concrete road 1 and side formworks 2 on both sides thereof, the side formworks 2 are metal formworks and are fixed by each pull rod, a movable frame is provided on the upper part of the concrete road 1, and the lower part of the movable frame is supported on the upper part of the side formworks 2 by multiple support wheels 4 on both sides, the metal side formworks 2 have good support, and prevent the support wheels 4 from disturbing the internal concrete road 1 plane, and multiple adjustable and movable film loaders are provided in the front and rear staggered positions on the upper part of the movable frame. The multiple staggered film loaders can make the subsequently unfolded covering film 9 laid and overlapped together to achieve dead angle laying, thereby ensuring the closedness of the laying, and the film roll 8 installed on the film loader is moved by the movable frame to lay the wound covering film 9 on the pavement of the concrete road 1.
[0019] like Figure 1As shown, the movable frame includes support frames 3 on both sides, and the support frames 3 are connected and fixed by multiple sliding rods 5. The movable frame and the support frames 3 are made of aluminum alloy to greatly reduce the weight of the device and reduce the pressure on the side template 2.
[0020] like Figure 2 As shown, the support wheel 4 is laterally installed at the lower side end of the support frame 3, and an annular retaining ring 401 is provided on the outside of the support wheel 4. The annular retaining ring 401 is located outside the side template 2 to prevent the support wheel 4 from separating from the side template 2 when moving.
[0021] like Figure 2 As shown, the film loader includes a sliding sleeve 6 that is slidably connected to the corresponding slide rod 5. The position of the film loader is changed by sliding the sliding sleeve 6 on the slide rod 5, so the overlap width of the film roll 8 of the film loader can be changed, and laying can be achieved even in severe windy weather (the overlap width can be widened in windy weather to avoid wind disturbance). An L-shaped support rod 7 is installed at the bottom of the sliding sleeve 6, and a rotatable film roll 8 is installed on the side of the L-shaped support rod 7.
[0022] like Figure 1 As shown, a locking screw 10 is installed on the sliding sleeve 6 for locking with the sliding rod 5. The fixed adjustment of the sliding sleeve 6 is achieved by tightening and loosening the locking screw 10. The outer end of the L-shaped support rod 7 is screwed with a limit block for limiting the falling off of the film roll 8. When the covering film 9 of the film roll 8 is used up, the limit block can be loosened to quickly replace the film roll 8.
[0023] like Figure 1 As shown, the covering films 9 of the plurality of film rolls 8 are laid on the pavement of the concrete road 1 in an overlapping manner at adjacent locations.
[0024] like Figure 1 As shown, the covering film 9 on both sides of the concrete road 1 is located under the supporting wheels 4 during laying. The supporting wheels 4 at the rear ends of both sides press the covering film 9 to achieve a guiding and fixing effect, ensuring that the covering film 9 on the edges of both sides can completely cover the outer edges of the concrete road 1, thereby ensuring the integrity of the paving.
[0025] like Figure 2 As shown, it also includes a walking system, which includes a battery box 12 installed on the side of the support frame 3. The battery box 12 is electrically connected to the controller 13 on the upper part. The controller 13 is electrically connected to the drive motor 11 installed on the side of the support frame 3 for driving the support wheel 4 to rotate. The drive motor 11 is installed on the support wheel 4 at the front end of the side of the support frame 3 to facilitate direction control. The controller 13, that is, the control box controls the battery box 12 to supply power to the drive motor 11, thereby ensuring that the device can move forward smoothly.
[0026] The implementation principle of a road construction film laying device in the embodiment of the present application is as follows:
[0027] After the concrete road 1 is initially poured (the surface has not solidified), the device is hoisted to the initial section of the concrete road 1 by a crane and the multiple support wheels 4 on both sides are placed on the side templates 2. Then, the covering films 9 of the multiple film rolls 8 at the lower part of the mobile frame are pulled out and laid on the wet concrete road 1 surface to achieve bonding. Then, the controller 13 is operated to start the battery box 12 to power the drive motor 11. The drive motor 11 drives the support wheels 4 at the front ends of the side support frames 3 on both sides to rotate, so that the entire mobile frame moves forward along the concrete road 1. During the forward movement, the covering films 9 of the multiple film rolls 8 will be released as they rotate forward and laid on the concrete road 1 surface, thereby achieving rapid laying of the covering film 9. The entire laying process not only saves time and effort but also greatly improves the laying efficiency. At the same time, it is laid before the concrete road 1 is solidified. The covering film 9 has a better fit with the relatively wet concrete road 1, which better prevents the loss of water in the concrete road 1 and ensures the service life of the concrete road 1.
