Description

Technical Field

[0001] The utility model relates to the technical field of film coating devices, in particular to a device which cooperates with a paver to automatically coat and cure bridge deck concrete. Background Art

[0002] Concrete roads need to go through a hydration and hardening process for a period of time after construction. If this hydration process is not completed and water loss occurs, it will cause incomplete hydration and shrinkage cracks on the road surface, which will cause great harm to the stability of the road. Therefore, the surface of the newly built concrete road will be covered with plastic film to prevent the water in the concrete from evaporating too quickly. Not only that, the plastic film can also keep the road surface warm and prevent temperature cracks caused by excessive temperature difference between the inside and outside of the concrete.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] Examples, such as Figures 1 to 6As shown, the utility model provides a device for automatically coating and curing bridge deck concrete in cooperation with a paver, comprising a paver 1, a rotating shaft 2 is welded to the outer side of the paver 1, a first rotating arm 3 is sleeved on the outer side of the rotating shaft 2, an extension arm 4 is rotatably connected to the outer side of the first rotating arm 3, a fixing plate 5 is welded to the outer side of the extension arm 4, a wheel 9 inside a fixed frame 8 extrude a plastic film 16, and pushes downward a slide bar 12 inside a base 11, and a sleeve 13 at the bottom end of the slide bar 12 presses against a paving plate 22 to extrude the plastic film 16.

[0025] Specifically, the outer side of the fixed plate 5 is fixedly connected with a support rod 10, and the outer side of the support rod 10 is sleeved with a base 11. The sleeve 13 at the top of the paving plate 22 is tilted and pressed against the second telescopic rod 14 on the outer side of the fixed block 15. At this time, the second telescopic rod 14 presses the tilted sleeve 13 back to normal.

[0026] Furthermore, the bottom end of the extension arm 4 is connected to the extension rod 17 by a screw thread, the outer side of the extension rod 17 is rotatably connected to the second rotating arm 18, and the outer side of the pull rod 19 is sleeved with a second spring 20, which can be disassembled when not in use.

[0027] Furthermore, a cavity is opened inside the fixed block 15, and six groups of the second telescopic rod 14 and the fixed block 15 are arranged. The sleeve 13 is tilted and pressed against the second telescopic rod 14 outside the fixed block 15. At this time, the second telescopic rod 14 presses and rebounds the tilted sleeve 13, and setting six groups is more stable.

[0028] It is worth noting that the paving module 23 rotates inside the square groove at the bottom of the road paver 1, driving the road paver 1 to move.

[0029] It is worth noting that a pulley module 24 is fixedly connected to the bottom end of the paver 1 , and the pulley module 24 is provided in several groups, through which the cement is evenly spread.

[0030] It is worth mentioning that a scraper 21 is welded to the bottom end of the pull rod 19, and the scraper 21 is attached to the outside of the plastic film 16. The scraper 21 presses against the plastic film 16 to scrape it clean. When the thickness of the plastic film 16 is relatively thick, the plastic film 16 reduces the shock of the second spring 20 on the outside of the pull rod 19, and the scraper 21 is set to rubber material to protect the plastic film 16.

[0031] Working principle: First, when the staff slides the pulley module 24 at the bottom of the paver 1 forward, the paving module 23 inside the square groove paves the cement at the bottom. During the paving process, the first rotating arm 3 outside the paver 1 is rotated to be flush with the cement floor, and the plastic film 16 is laid on the cement floor. As the paver 1 moves, when encountering a rugged road surface, the first telescopic rod 6 inside the fixed plate 5 outside the extension arm 4 slides toward the inside of the fixed plate 5, and cooperates with the first spring 7 on the outside to reduce the shock of the wheel 9 at the bottom, and then the plastic film 16 is attached to the cement floor. At this time, the sliding rod 12 inside the base 11 is pushed downward, and the sleeve 13 at the bottom end of the sliding rod 12 presses against the paving plate 22 to squeeze the plastic film 16. When the paving plate 22 encounters an uneven ground, the sleeve 13 at the top of the paving plate 22 tilts and presses against the second telescopic rod 14 outside the fixed block 15. At this time, the second telescopic rod 14 presses the tilted sleeve 13 back to normal;

[0032] When the plastic film 16 needs to be rolled up for recycling, the extension arm 4 only needs to be rotated to ninety degrees with the first rotating arm 3. At this time, when the plastic film 16 is rolled up, the pull rod 19 is pushed to drive the scraper 21 to press against the plastic film 16 for scraping. When the thickness of the plastic film 16 is relatively thick, the plastic film 16 reduces the shock of the second spring 20 on the outside of the pull rod 19.

[0033] The above is only a preferred specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes according to the technical solution and concept of the present application within the technical scope disclosed in the present application, which should be covered by the protection scope of the present application.
