[0003] During the construction of existing building floors, the ground needs to be compacted manually, then the concrete mixture is poured into the construction site by machine, compacted by a manual vibration plate, and then the concrete mixture is repeatedly smoothed manually. This construction method has the defects of high labor intensity, low construction efficiency and poor flatness. Utility Model Content

[0004] The utility model aims to provide a floor laser leveling device to reduce labor intensity, improve construction efficiency and floor flatness.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a floor laser leveling device, including a laser detection unit and a mobile leveling mechanism, the laser detection unit is used to detect the flatness of the paved floor, the mobile leveling mechanism includes a mobile unit and a leveling unit, the mobile unit is used to drive the leveling unit to move, the leveling unit includes a bracket, a lifting part is provided on the top of the bracket, the lifting part is used to drive the bracket to rise and fall, and a scraping part, a cloth part, a leveling part and a trimming part are sequentially arranged on the bracket, the scraping part is detachably connected to the side of the bracket close to the mobile unit, the cloth part is rotatably connected to the bracket, and the leveling part and the trimming part are both fixedly connected to the bracket.

[0006] The beneficial effects of this solution are as follows: during the construction of concrete floor, after the concrete pouring is completed, the leveling unit is moved to the top of the concrete that needs to be leveled by the moving unit, and the leveling unit is driven down by the lifting unit so that the slurry scraping part contacts the concrete, and the leveling unit is driven to move by the moving unit. After the slurry scraping part scrapes off the excess slurry on the concrete surface, the spreading part spirally spreads the concrete to make the concrete spreading more uniform, and then the concrete after spreading is leveled by the leveling part. After the leveling part completes the leveling, the finishing part finally trims the minor defects on the concrete surface.

[0007] Due to the provision of the laser detection unit, the technical solution can check the designed ground elevation at any time before and during the pouring of concrete to ensure the accuracy requirement; at the same time, during the process of leveling the concrete, the flatness of the paved floor can also be detected in real time.

[0008] Due to the provision of a mobile leveling mechanism, this technical solution replaces the existing manual work with mechanization when leveling the concrete floor, thereby reducing labor intensity, shortening the construction period, improving construction efficiency and quality, and making the paved floor more flat.

[0009] Due to the arrangement of the scraping part, the spreading part, the leveling part and the finishing part, the technical solution can ensure good integrity of the leveled floor, reduce the occurrence of construction joints, thereby ensuring the strength of the concrete, making it less likely for cracks to appear on the leveled floor, and solving the problems of hollowing, peeling, cracking and unevenness.

[0010] Furthermore, the moving unit includes a moving trolley, a power member No. 1, and a rotating platform rotatably arranged on the top of the moving trolley, and the power member No. 1 is used to drive the rotating platform to rotate.

[0012] Furthermore, a spraying portion is provided on the bracket, and the spraying portion is arranged on a side of the trimming portion away from the moving unit.

[0013] The beneficial effect of this solution is that due to the provision of the spraying part, this technical solution can spray the curing agent on the leveled floor through the spraying part, thereby improving the density and dustproof performance of the concrete.

[0014] Furthermore, a cleaning unit is provided on the mobile trolley, and the cleaning unit is used to clean the mobile leveling mechanism.

[0017] The beneficial effects of this solution are as follows: when carrying out concrete floor construction, first determine the ground design elevation and the leveling base point, set the leveling rod on the leveling base point, and arrange the laser transmitter according to the leveling base point and the construction location to ensure that the laser beam is 2.74m from the ground, so that the laser receiver can receive the signal of the laser transmitter at any position during the construction of the mobile leveling mechanism; debug the portable receiver according to the ground design elevation and the elevation of the laser transmitter, and check the ground design elevation at any time before and during the pouring of concrete to ensure the accuracy requirement; in the process of leveling the concrete, the flatness of the paved floor is detected in real time by the laser receiver.

[0018] Furthermore, the cleaning unit includes a water tank and a storage box, both of which are fixedly connected to the mobile trolley. A water inlet is provided on the top of the water tank, and a sealing cover is detachably connected to the water inlet. The bottom of the water tank is connected to a water outlet pipe, a one-way valve is installed on the water outlet pipe, and a water spray gun is detachably connected to the water outlet pipe, which can be stored in the storage box.
