[0018] The following will be combined with the embodiments to clearly and completely describe the technical solution 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 of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-Figure 2 , the utility model provides a technical solution:

[0020] Example:

[0021] like Figure 1 As shown, a concrete film covering device comprises a support plate 1, on which a support portion for supporting a film tube is provided, and a pressure rod 2 for the film to pass through is also provided on the support plate 1, and the support plate 1 is connected to a pull rod 3 for driving the support plate 1 to move.

[0022] The support portion includes two rib plates 4 , one of which is provided with a horizontal fixing shaft 5 , and the other rib plate 4 is provided with a detachable horizontal bolt 6 .

[0023] The bottom of the support plate 1 is horizontal, and the two long sides of the support plate 1 are inclined upward.

[0024] The support plate 1 is provided with two ear plates, and the two ends of the pressure rod 2 are respectively fixed to the two ear plates.

[0025] The two ends of the pressure rod 2 are fixed to the two ear plates by bonding or welding.

[0026] The support plate 1 is provided with an inclined connecting sleeve 7 , and the pull rod 3 is connected to the support plate 1 via the connecting sleeve 7 .

[0027] The connecting sleeve 7 is provided with a screw hole, and the pull rod 3 is fixed to the connecting sleeve 7 through the screw and the screw hole.

[0028] Wherein, reinforcing ribs are provided on both sides of the connecting sleeve 7.

[0029] Working principle: (1) Align the center of the film tube used for covering concrete with the fixed shaft 5 without bolt 6, unscrew the bolt at the other end, align the center of the film roll with the bolt 6 hole, and then screw on the bolt 6. Pass the film head under the front pressure rod 2 and cover it on the concrete, press and pull the pull rod 3 to move backward.

[0030] (2) Relying on the weight of the concrete film covering device and the film itself, the device exerts a downward force on the concrete to achieve the effect of closing the surface. According to the adhesion between the film and the concrete, when the direction handle is pulled backward, the film will rotate and pull out the film to cover the concrete.

[0031] The utility model can realize rapid film covering of concrete by arranging the film covering device, and only needs one person to operate it, thereby saving human resources and improving the film covering efficiency.

[0032] Furthermore, if Figure 2 As shown, a male buckle 8 is coaxially arranged on the top of the connecting sleeve 7, the top of the male buckle 8 is a multi-petal structure, an external thread is arranged in the middle of the male buckle 8, the pull rod 3 passes through the male buckle 8 coaxially, and the external thread of the male buckle 8 is connected with a female buckle 9, and the female buckle 9 presses the top of the male buckle 8 against the outside of the pull rod 3. (Wherein, the top of the female buckle 9 is a truncated cone hole structure, and when the female buckle 9 is screwed down, the internal truncated cone hole tightens the petal at the top of the male buckle 8).

[0033] The male buckle 8 is fixed to the connecting sleeve 7 by welding.

[0034] Before the pull rod 3 is fixed to the connecting sleeve 7, the female buckle 9 is first screwed upwards out of the male buckle 8, and then the pull rod 3 is passed through the female buckle 9 and the male buckle 8. After the pull rod 3 is passed through, the female buckle 9 is screwed down to reset the female buckle 9. When the female buckle 9 is reset, the petals at the top of the male buckle 8 are tightened, so that multiple petals are pressed against the outside of the pull rod 3, thereby fixing the pull rod 3.

[0035] The pull rod is detachably connected to the connecting sleeve via a male buckle and a female buckle, which facilitates the disassembly of the pull rod.

[0036] The above is only a preferred embodiment of the utility model. It should be understood that the utility model is not limited to the form disclosed herein, and should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be modified within the scope of the concept described herein through the above teachings or the technology or knowledge of the relevant field. The changes and modifications made by those skilled in the art do not deviate from the spirit and scope of the utility model, and should be within the scope of protection of the claims attached to the utility model.
