Description

Technical Field

[0001] The utility model relates to the technical field of concrete, in particular to a rolling device used for covering with a curing film after concrete pouring construction. Background Art

[0002] Concrete pouring construction refers to the process of pouring concrete into a mold until it is plasticized. Common concrete pouring construction projects include: concrete pouring of floors, concrete pouring of stairs, concrete pouring of beams and slabs, etc. During concrete pouring, cement of a specified strength is mixed with an appropriate amount of sand, gravel, and admixtures, and then poured into the specified mold using a pump or other means of transportation. The concrete is then allowed to harden and form for a period of time.

[0003] In order to protect the initial moisture of concrete and prevent its evaporation, thereby reducing the early cracks caused by insufficient moisture during the hardening process of concrete, it is necessary to manually cover the surface of the concrete with ground film to lock in its moisture and prevent it from cracking.

[0004] However, when covering the concrete surface with ground film, it is necessary to manually pull the ground film to move on the surface of the newly poured concrete. Therefore, during the covering process, the workers will step into the newly poured concrete, thereby destroying the flatness of its surface. Therefore, the workers need to perform an additional smoothing operation on the concrete surface later, and the operation is relatively cumbersome. Therefore, it does not meet the existing needs. In this regard, we propose a rolling device for covering the curing film after concrete pouring construction. Utility Model Content

Therefore, during the covering process, the workers will step into the freshly poured concrete, thereby destroying the flatness of its surface. Therefore, the workers need to perform an additional smoothing operation on the concrete surface later, and the operation is relatively cumbersome.

[0024] See also Figures 1 to 4 The utility model provides an embodiment: a rolling device for covering with a curing film after concrete pouring construction, comprising a curing film covering device base 1, a curing film covering device base B4 being provided on one side of the curing film covering device base A1, a connecting plate A3 being fixedly provided on the surface of the curing film covering device base A1 facing the curing film covering device base B4, a connecting plate B5 being fixedly provided on the surface of the curing film covering device base B4 facing the curing film covering device base A1, an extension plate 7 being provided between the curing film covering device base B4 and the connecting plate B5, a strip-shaped fixing head 8 being fixedly provided on the front end surfaces of the connecting plate B5 and the extension plate 7, a strip-shaped fixing groove 9 being provided on the rear end surfaces of the connecting plate A3 and the extension plate 7, and a level sensor 6 being fixedly installed on one side of the upper end surface of the connecting plate A3 and the curing film covering device base B4;

[0025] The lower end surfaces of the connecting plate A3, the connecting plate B5 and the extended plate 7 are all fixed with a T-shaped slide rail 10, and the outer surface of the T-shaped slide rail 10 fixed to the lower end surface of the connecting plate B5 is installed with a slider 11, and the lower end surface of the slider 11 is fixed with a lifting platform 12, and the lower end surface of the lifting platform 12 is fixed with a convex plate 13. A horizontal bar cylinder 14 is installed on both sides of the outer surface of the convex plate 13, and the piston rod of the horizontal bar cylinder 14 is connected to the push plate 15. The opposite surfaces of the two pushing plates 15 are each installed with a cross-section cam wheel 16 through a roller bearing, and a ground film roller 17 is provided between the two cross-section cam wheels 16. The top end of the cross-section cam wheel 16 is located inside the ground film roller 17, and the surfaces of the cross-section cam wheel 16 facing the two ends of the ground film roller 17 are in contact with the ground film roller 17.

[0026] A screw fixing port 19 is provided on both sides above the strip fixing groove 9, and a screw connection groove 20 is provided on the outer surface of the strip fixing head 8 at a position corresponding to the screw fixing port 19; the positions of the T-shaped slide rails 10 installed on the lower end surfaces of the connecting plate A3, the extension plate 7 and the connecting plate B5 correspond to each other, and both sides of the three T-shaped slide rails 10 are flat; when it is necessary to use this equipment, a corresponding number of extension plates 7 can be installed between the connecting plate A3 and the connecting plate B5 according to the length of the concrete surface to be coated. When it is necessary to install the extension plate 7, align the strip fixing head 8 located on the outer surface of the extension plate 7 with the strip fixing groove 9 located on the rear end face of the connecting plate A3, and then insert it. After the strip fixing head 8 is inserted into the interior of the strip fixing groove 9, it is tightened by screws and the strip fixing groove 9 and the screw fixing port 19 above the strip fixing head 8 and the screw connecting groove 20 above the strip fixing head 8 fix the strip fixing head 8 and the strip fixing groove 9 to prevent the connection between the two from loosening. When the total length of the connecting plate A3, the connecting plate B5 and the T-shaped slide rail 10 on the lower end face of the extension plate 7 is longer than the length of the concrete surface, the extension plate 7 is no longer installed, and the connecting plate B5 is installed on the rear end face of the extension plate 7 at the rear through the same installation method. When the extension plate 7 and the connecting plate B5 are installed, the T-shaped slide rail 10 on the lower end face of the connecting plate A3, the extension plate 7 and the connecting plate B5 will be connected. Through the above technical solution, the present equipment can perform coating operations on concrete of various different lengths, thereby improving the adaptability of the equipment.

[0027] A control panel 2 is fixedly installed on one side of the upper end surface of the base A1 of the curing film covering device, and the control panel 2 is electrically connected to the level sensor 6, the slider 11, the lifting platform 12 and the horizontal bar cylinder 14; the slider 11, the lifting platform 12 and the horizontal bar cylinder 14 can be controlled through the control panel 2.

[0028] A pulley 18 is installed on both sides of the lower end surface of the curing film covering device base A1 and the curing film covering device base B4, and the curing film covering device base A1 and the curing film covering device base B4 are fixed to the pulley 18 by screws; the outer surface of the extension plate 7 is wrapped with a ground film, and the lower end surface of the extension plate 7 is lower than the lower end surface of the pushing plate 15; after the corresponding number of extension plates 7 are installed between the connecting plate A3 and the connecting plate B5, the curing film covering device base A1 and the curing film covering device base B4 are placed on the construction frame on both sides of the poured concrete through the pulleys 18 installed on the lower end surfaces of the curing film covering device base A1 and the curing film covering device base B4, and then the convex plate 13 is moved downward by the lifting platform 12, and as the convex plate 1 3 descends and the ground film roller 17 inside it will descend along with it. When the ground film roller 17 contacts the concrete, the ground film wrapped around the outer surface of the ground film roller 17 can be adsorbed to the surface of the concrete through the adsorption of the concrete. Then the slider 11 drives the lifting platform 12 to move along the connected T-shaped slide rail 10. During the movement of the lifting platform 12, the ground film roller 17 will move on the concrete surface. During the movement of the concrete surface, the ground film roller 17 can automatically cover the outer surface of the concrete with the ground film. Through the above technical solution, the concrete covering operation no longer requires workers to step into the concrete to operate, so that no additional smoothing operation is required in the later stage, thereby improving the convenience of the concrete covering operation.

[0029] When the film roller 17 moves to the end of the concrete, the film covering the concrete surface and the film still wrapped around the outer surface of the film roller 17 are cut apart, and then the entire device is moved by the pulley 18 respectively installed on the base 1 of the curing film covering device and the lower end surface of the base B4 of the curing film covering device, so as to move the film roller 17 to the area on the concrete that has not yet been covered for covering operation.

[0030] By means of two level sensors 6 respectively installed on the upper end surfaces of the connecting plate A3 and the connecting plate B5, the level data of the entire equipment can be obtained and the data can be transmitted to the control panel 2. If the equipment as a whole is in a tilted state, the ground film roller 17 moves on the concrete surface. The control panel 2 can control the height of the ground film roller 17 during movement through the lifting platform 12, so as to ensure that the ground film roller 17 always maintains parallel movement. The above technical solution can prevent the situation where the moving ground film roller 17 directly hits the interior of the concrete due to the tilt of the entire equipment.

[0031] The outer surface of the cross-section cam wheel 16 located inside the ground film roller 17 fits with the inner wall of the ground film roller 17, and the cross-section cam wheel 16 and the ground film roller 17 are slidingly connected; when the ground film wrapped around the outer surface of the ground film roller 17 is used up, the push plate 15 and the cross-section cam wheel 16 are pulled outward by the horizontal bar cylinder 14 to release the clamping of the ground film roller 17, and then a new ground film roller 17 is placed between the two cross-section cam wheels 16. When the new ground film roller 17 is placed The cross-section cam wheel 16 and the pushing plate 15 are pushed toward the ground film roller 17 through the horizontal bar cylinder 14. When the top end of the cross-section cam wheel 16 enters the interior of the ground film roller 17 and the surface facing the end face of the ground film roller 17 fits with the ground film roller 17, the new ground film roller 17 is fixed. Since the cross-section cam wheel 16 and the pushing plate 15 are connected by a roller bearing, there is no need to worry about the ground film roller 17 being unable to rotate due to its clamping force.

[0032] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
