DETAILED DESCRIPTION

[0043] Clearly, the described embodiments are merely a part of the embodiments of the present application, but not all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.

[0044] Please refer to Figures 1-5 The utility model provides a technical scheme: a kind of new pouring concrete surface plastic film covering device, including mounting bracket 2, the upper side of mounting bracket 2 is connected with winding roller 1 by mounting bearing horizontally and rotates, winding roller 1 is used to winding plastic film, the front end of mounting bracket 2 walking direction is connected with rotating shaft by bearing and rotates horizontally, rotating shaft is coaxially connected with guide roller 3, one end of plastic film unwound on winding roller 1 passes through guide roller 3, the end of plastic film passing through guide roller 3 extends towards the rear end direction of mounting bracket 2 walking direction, mounting bracket 2 is straddled on concrete structure, the axial length of guide roller 3 is matched with the width size of concrete structure, in addition, guide roller 3 rolls on the surface of concrete structure, when mounting bracket 2 rolls on the surface of concrete structure, plastic film is laid on the surface of concrete structure, with the rolling of guide roller 3, plastic film is unwound from winding roller 1, so that plastic film can be laid on the surface of concrete structure with the movement of mounting bracket 2;

[0045] One support plate 6 is welded to the opposite side of mounting bracket 2 respectively, two support plates 6 correspond to the axial two sides of guide roller 3 respectively, hollow sliding groove 15 is formed in two support plates 6, the length direction of sliding groove 15 is consistent with the walking direction of mounting bracket 2, sliding seat 8 is clamped in two sliding grooves 15, connecting block 16 is connected to the bottom of sliding seat 8, pulling plate 7 is fixedly connected to the bottom of connecting block 16, a plurality of ratchet teeth 17 are arranged on the bottom surface of pulling plate 7, ratchet teeth 17 are inclined away from guide roller 3, rotating arm 4 is sleeved to the two ends of rotating shaft, hinged lever 5 is hinged to two rotating arms 4 respectively, the other end of length direction of hinged lever 5 is hinged to the two ends of length direction of sliding seat 8 respectively.

[0046] When the guide roller 3 rolls on the surface of the concrete structure, the rotating shaft will be rotated, and the rotating shaft will drive the rotating arm 4 to rotate, and the rotation of the rotating arm 4 will drive the hinged rod 5 to swing. Since the hinged rod 5, the sliding seat 8 and the rotating arm 4 constitute a crank slider mechanism, the swinging of the hinged rod 5 will drive the sliding seat 8 to move horizontally reciprocatingly. When the sliding seat 8 moves towards the direction of the guide roller 3, the inclined surface of the ratchet 17 will slide on the surface of the plastic film which has been laid on the concrete structure, because the tip of the ratchet 17 is inclined away from the guide roller 3. When the sliding seat 8 moves away from the direction of the guide roller 3, the tip of the ratchet 17 will press the surface of the plastic film, so that the plastic film is subjected to a pulling force, thereby avoiding the phenomenon of wrinkles of the plastic film on the guide roller 3 during the laying process. The pulling plate 7 is made of rubber material, so that the pulling plate 7 will not generate a large extrusion force on the plastic film. In addition, the surface of the guide roller 3 is provided with a silica gel layer, so that the plastic film is not easy to slide on the surface of the guide roller 3, thereby reducing the wrinkling phenomenon of the plastic film.

[0047] The rear end of the installation frame 2 in the walking direction is vertically provided with two sliding columns 10, the sliding columns 10 can freely slide up and down on the installation frame 2, the lower ends of the two sliding columns 10 are commonly welded with a troweling plate 9, the troweling plate 9 is welded with an upwardly curved deformation avoiding portion 14 on each side corresponding to the walking direction of the installation frame 2, a stop ring 11 is sleeved on the sliding column 10, the stop ring 11 is located above the troweling plate 9, a spring 12 is sleeved around the sliding column 10, the spring 12 is elastically abutted against the stop ring 11 and the installation frame 2 at both ends of the elastic force direction, and a nut 13 is threadedly sleeved on the upper end of the sliding column 10;

[0048] When the installation frame 2 moves, the elastic abutment force of the spring 12 on the stop ring 11 makes the sliding column 10 drive the troweling plate 9 to generate sufficient pressure on the plastic film laid on the surface of the concrete structure, so that the plastic film is laid flat on the surface of the concrete structure by the pressure of the troweling plate 9 when the installation frame 2 moves. In addition, by providing the avoiding portion 14, the edge of the troweling plate 9 is prevented from scratching the plastic film.

[0049] The working principle of the utility model discloses: the mounting frame 2 is crossed on the concrete structure, the axial length of the guide roller 3 is matched with the width size of the concrete structure, in addition the guide roller 3 rolls on the surface of the concrete structure, when the mounting frame 2 rolls on the surface of the concrete structure, the plastic film is laid on the surface of the concrete structure, along with the rolling of the guide roller 3, the plastic film will be unwound from the winding roller 1, so that the plastic film can be laid on the surface of the concrete structure along with the movement of the mounting frame 2, when the guide roller 3 rolls on the surface of the concrete structure, the rotating shaft will be driven to rotate, when the rotating shaft rotates, the rotating arm 4 will be driven to rotate, the rotation of the rotating arm 4 will drive the hinged rod 5 to swing, because the hinged rod 5, sliding seat 8 and rotating arm 4 constitute a slider-crank mechanism, therefore the swing of the hinged rod 5 will drive the sliding seat 8 to reciprocate horizontally, when the sliding seat 8 moves towards the direction of the guide roller 3, because the tip of the ratchet 17 is inclined away from the direction of the guide roller 3, therefore the inclined surface of the ratchet 17 will slide on the surface of the plastic film that has been laid on the concrete structure, and when the sliding seat 8 moves away from the direction of the guide roller 3, the tip of the ratchet 17 will press the surface of the plastic film, so that the plastic film is subjected to pulling force, thereby avoiding the plastic film on the guide roller 3 from being wrinkled during the laying process, when the mounting frame 2 walks, the elastic resistance of the spring 12 to the stop ring 11 makes the sliding column 10 drive the smoothing plate 9 to generate enough pressure on the plastic film laid on the surface of the concrete structure, so that when the mounting frame 2 moves, the plastic film is smoothed and laid on the surface of the concrete structure by the pressure of the smoothing plate 9, in addition, by setting the avoiding part 14, the edge of the smoothing plate 9 avoids scratching the plastic film.
