Description

Technical Field

[0001] This utility model belongs to the field of concrete floor construction technology, and in particular relates to a concrete floor grouting device. Background Technology

[0002] A concrete floor is a floor formed by pouring concrete. Concrete floors are mostly used as horizontal floors in production plants. During the construction of a concrete floor, workers pour concrete of a certain grade onto the foundation. Then, to achieve a smooth surface, a thin concrete slurry of a certain concentration is poured onto the concrete foundation.

[0003] To maintain a high level of concrete surface, a scraper is used during construction to level the concrete slurry, ensuring a smooth surface.

[0004] Currently, during construction, workers use handheld scrapers of a certain length. This method is particularly challenging when working on large areas. For example, factory floors are often large, and if the concrete slurry layer isn't leveled and smoothed promptly, the initially poured concrete is prone to drying out due to excessive evaporation. Once dried, leveling is not only difficult but also often impossible.

[0005] Meanwhile, construction workers use a scraper of a certain length to scrape the surface, which requires them to use their hands as the center and rotate the scraper to level it. However, the longer the scraper, the more likely the outer end will tilt downwards during the scraping process, making it impossible to ensure the levelness and thus preventing the surface from being leveled.

[0046] Example 1

[0047] like Figure 1-5 As shown, a concrete floor scraping device includes a scraping mechanism, which includes an annular rotating frame 13 on which a plurality of scraping plate assemblies 1 are mounted.

[0048] Specifically, the scraper assembly 1 includes a fixed adjustment frame 11 mounted on an annular rotating frame 13, and the fixed adjustment frame 11 is equipped with a scraper 12 via an adjustment structure.

[0049] The fixed adjustment bracket 11 has the following shape: the inner end of the fixed adjustment bracket 11 is integrally formed with a bent mounting part that is bent downwards, and the fixed adjustment bracket 11 also includes a horizontal part of the integrally formed bent mounting part.

[0050] The specific method is as follows: a notch is provided at the bottom of the curved mounting part, and the annular rotating frame 13 is limited within the notch (the notch method ensures that during rotation, the annular rotating frame 13 is limited within the notch, so the curved mounting part is pressed against the annular rotating frame 13 and is not easy to rotate relative to the annular rotating frame 13).

[0051] Meanwhile, the curved mounting part is installed on the annular rotating frame 13 in an elastic telescopic manner via a spring screw.

[0052] Specifically, the spring screw component includes a screw 16 fixedly connected to the top of the annular rotating frame 13, and the screw 16 is slidably connected to the bent mounting part; a spring 161 is sleeved on the screw 16, and the two ends of the spring 161 are fixedly connected to the bent mounting part and the annular rotating frame 13 respectively; a locking nut is threadedly connected to the screw 16.

[0053] The curved mounting part is locked by pressing down the locking nut. Since the screw 16 is fitted with a spring 161, when encountering uneven concrete slurry during the rotation and leveling process, the scraper 12 is buffered by the spring structure. Specifically, when the scraper 12 is under force in an uneven state, it slides up and down slightly through the screw, and the spring stretches and deforms during this process.

[0054] The bottom of the aforementioned horizontal section is provided with a sliding groove; an inner long sliding rod 13 is fixedly connected in the sliding groove, and the inner long sliding rod 13 is slidably connected to the scraper 12; the shape of the scraper 12 is as follows: the scraper 12 includes a scraper part, and a rectangular sliding part 121 is integrally formed on the top of the scraper part, and the rectangular sliding part 121 is slidably connected in the sliding groove.

[0055] During operation, adjustment is achieved by sliding the scraper 12 within the groove. Simultaneously, the top of the scraper 12 is threadedly connected to a pressing screw that is locked within the inner long slide rod 13. During operation, releasing the pressing screw allows for sliding adjustment of the scraper 12; for example, sliding the scraper 12 outwards adjusts the scraping position.

[0056] In actual operation, a nut that is blocked on the horizontal part is threaded onto the outer end of the inner long slide rod 13 to prevent the scraper 12 from rotating and being thrown off.

[0057] Example 2

[0058] like Figure 1-5 As shown, based on the structure of Embodiment 1, the above-mentioned scraping mechanism further includes a motor 2 that drives the annular rotating frame 13 to rotate; a motor bracket is fixedly connected to the top of the motor 2, and a hand-lifting slide rail 4 is slidably connected to the upper end of the motor bracket; and pull ropes 3 are fixedly connected to both ends of the motor 2 bracket.

[0059] Specifically, a number of folded mounting arms 14 are fixedly connected to the top of the annular rotating frame 13, and a connecting frame 142 is fixedly connected between the upper ends of the folded mounting arms 14.

[0060] The connecting frame 142 is fixedly connected to the connecting shaft 141, and the output shaft of the motor 2 is mounted on the connecting shaft 141 through a flange.

[0061] The motor bracket includes a bracket plate 22 fixedly connected to the top of the motor 2, with vertical mounting screws fastened to the motor 2 at both ends of the bracket plate 22; the motor 2 bracket also includes a fixing rod 21 fixedly connected to the top of the bracket plate 22. A slide block 212 is fixedly connected to the top of the fixing rod 21, and the hand-held slide rail 4 is slidably connected to the slide block 212; handles 41 are fixedly connected to both ends of the hand-held slide rail 4.

[0062] Meanwhile, a collar 211 is rotatably connected to the fixed rod 21 (the diameter of the collar 211 is fixedly connected to the diameter rod of the fixed rod 21); the two ends of the collar 211 are respectively fixedly connected to the pull rope 3.

[0063] During operation, the operator helps to raise both ends of the hand-operated slide rail 4 and keep it level (a level can be installed on the top of the hand-operated slide rail 4 according to the existing method). Then, the slurry scraper is rotated. After scraping for a period of time, the operator pulls the pull rope 3 by hand. At this time, the motor 2 bracket slides on the hand-operated slide rail 4 and adjusts the slurry scraping position.

[0064] The above methods increase the efficiency of grouting and allow for flexible adjustment of the grouting position during the grouting process. This improves the efficiency of concrete pouring operations on large areas of the ground while reducing the workload and difficulty of the work.

[0065] In actual operation, a sling can be installed on the handle. The length of the sling can be adjusted according to the operator's height, and the sling can be pulled up to the operator's arm or neck, freeing up both hands and further increasing the flexibility of operation.

[0066] Example 3

[0067] like Figure 1-5 As shown, in this embodiment, based on the structure of embodiment 1, since the scraper and the fixed adjustment frame 11 have a certain length, in order to increase the stability during the scraping process and maintain a high level, the top of the screw is fixedly connected to a diagonal steel wire rope structure; the diagonal steel wire rope structure includes a vertical rod 15 that is vertically fixedly connected to the top of the screw, and a diagonal steel rope A is fixedly connected to the vertical rod 15; the diagonal steel rope A is fixedly connected to the top outer side of the fixed adjustment frame 11.

[0068] The aforementioned inclined steel rope A is used to maintain a high degree of horizontality for the entire device by inclined tension.

[0069] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
