Description

Technical Field

[0001] The utility model relates to the field of highway construction, in particular to a film laying device for highway construction. Background Art

[0002] Highway construction refers to the general term for highway network planning, highway survey and design, highway construction, maintenance, and management. After pouring concrete, the pavement or roadbed made of concrete often needs to be covered with a film for maintenance. The film will effectively isolate the moisture on the concrete surface from the atmosphere, reduce the evaporation of moisture, and preserve the moisture volatilized in the initial stage of the concrete. The film covering allows the moisture to fully react with the cement in the concrete, reducing the internal stress caused by insufficient moisture during the hydration process and causing early cracks in the concrete. It also has a certain thermal insulation effect, forming a self-curing environment. The covering time should be when there is still water on the concrete surface after vibration.

[0003] The film needs to be fully covered on the surface of the newly poured concrete. The existing film covering work is mostly done by workers manually rolling the film on the concrete surface, which is inefficient. In actual operation, workers sometimes walk on the newly poured concrete surface, which affects the flatness of the concrete surface. For this reason, we proposed a road construction film laying equipment. Utility Model Content

[0006] Furthermore: the film roller assembly includes a plurality of roller bodies, the combined length of the plurality of roller bodies is not less than the width of the road, and the outer walls of the roller bodies are provided with limiting grooves.

[0007] Furthermore: the outer wall of the roller body is slidably connected with a movable baffle, one end of the movable baffle is slidably connected with a plug, and one end of the plug is plugged into a limiting groove.

[0008] Furthermore: the inner wall of the limiting groove is provided with uniformly distributed transverse racks, and the size of the outer wall of one end of the plug close to the limiting groove is adapted to the size of the racks.

[0009] Further: the support mechanism includes a stud and a screw barrel, the adjacent side of the two studs is threadedly connected with a screw barrel, and the other end of the stud is threadedly connected to the inner wall of the side plate.

[0010] Further: both ends of the roller body are respectively provided with plug holes or plug blocks with matching sizes, and one end of the roller body is plugged into the inner wall of the side plate.

[0011] Further: the outer wall of the side plate is rotatably connected with a push rod.

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3 The figure shows a preferred embodiment of the utility model, a road construction film laying equipment, including two side plates 1, the bottom of the two side plates 1 are fixedly installed with universal wheels 2; a plurality of film roller assemblies 3 and a supporting mechanism 4 that can adapt to the width of the road are arranged between the two side plates 1, and the film roller assembly 3 is used for laying multiple rolls of film at the same time.

[0020] Specifically, the film roller assembly 3 includes a plurality of roller bodies 5, the combined length of the plurality of roller bodies 5 is not less than the width of the road, and the outer walls of the roller bodies 5 are provided with limiting grooves 6; it should be supplemented that the number of roller bodies 5 is adjusted with the width of the road.

[0021] Among them, the outer wall of the roller body 5 is slidably connected with a movable baffle 7, one end of the movable baffle 7 is slidably connected with a plug 8, one end of the plug 8 is inserted into a limiting groove 6, and the film roll wrapped with the film can be put on the roller body 5 before the device is assembled. The two movable baffles 7 are fixed on the roller body 5 by the plug 8, thereby limiting the sliding of the film roll on the roller body 5, so that the film is laid in a fixed position.

[0022] It can be understood that the inner wall of the limiting groove 6 is provided with uniformly distributed transverse racks, and the size of the outer wall of the end of the bolt 8 close to the limiting groove 6 is adapted to the size of the racks; the main body of the bolt 8 enters the gap between the racks on both sides of the limiting groove 6, and another set of racks is provided on the outside of the bolt 8, which limits the position of the bolt 8 and prevents it from moving after the bolt 8 is inserted into the limiting groove 6.

[0023] Specifically, the supporting mechanism 4 includes studs 9 and screw barrels 10. The screw barrels 10 are threadedly connected to the sides of the two studs 9 that are close to each other. The other end of the stud 9 is threadedly connected to the inner wall of the side plate 1. Similar to the roller body 5, a number of studs 9 and screw barrels 10 are combined together to support the inner sides of the two side plates 1 and adapt to the length of the roller body 5. It should be supplemented that the supporting mechanism 4 is not less than three groups and is distributed in an inverted triangle. When the bottom supporting mechanism 4 is coated, the film body hangs down from the side of the supporting mechanism 4 close to the forward direction and spreads from its bottom to the side away from the forward direction. During the process, the film body can be tensioned by this group of supporting mechanisms 4 to avoid turbulence caused by the airflow around the film body.

[0024] Specifically, in order to connect the multiple roller bodies 5 , both ends of the roller body 5 are respectively provided with plug holes or plug blocks with matching sizes, and one end of the roller body 5 is plugged into the inner wall of the side plate 1 .

[0025] In order to facilitate the movement of the side plate 1 , a push rod 11 is rotatably connected to the outer wall of the side plate 1 .

[0026] In this embodiment, before assembling the device, the length and number of the roller bodies 5 need to be adjusted according to the width of the road and the width of the film. Before laying the film, the film roll wrapped with the film is sleeved outside the roller body 5, and the two movable baffles 7 are fixed on the roller body 5 by bolts 8, thereby limiting the sliding of the film roll on the roller body 5, so that the film is laid at a fixed position. After multiple groups of roller bodies 5 are fixed, multiple rolls of film can be laid at the same time;

[0027] It should be added that after the device is assembled, before laying the film, one end of the film needs to be removed in advance and fixed at the starting point of the film laying point by heavy pressure or other means. Then the construction personnel can push the device forward through the push rod 11 to make the film unfold as the device moves forward. It should also be noted that since the length of the roller body 5 is not less than the width of the road to be laid, the push rod 11 is located on the outside of the road. During the film laying process, it does not need to contact the top of the road, which will not cause adverse effects on the flatness of the initial concrete poured at this location, and it is also convenient for the later film removal.

[0028] Finally, it should be noted that in the description of the present invention, it should be noted that the terms "vertical", "up", "down", "horizontal", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0029] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly stipulated and limited, the terms "set", "install", "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal connection of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.
