[0001] The utility model relates to the technical field of building engineering construction, in particular to a ground leveling mechanism for building engineering. Background Art

[0002] Ground leveling refers to leveling the original ground of a building through certain methods so that the ground flatness reaches a certain standard and complies with national regulations on ground leveling. Ground leveling can be divided into two types: one is the original cement mortar ground leveling, and the other is the widely used self-leveling cement leveling.

[0003] After searching, the patent application with Chinese patent publication number CN212957529U discloses an assembled floor leveling structure, which mainly uses a detachable assembled leveling mechanism to facilitate workers to replace and use different leveling rollers, and at the same time replaces the traditional manual hand-held scraper to level cement mortar, which not only improves the work efficiency of workers, but also ensures the quality of cement mortar leveling.

[0004] Compared with the existing technologies in related fields, it can be seen that the concrete used for paving the floor is a mixture of lime, gravel, sand, etc. When laying concrete on the floor indoors, the degree of uniformity of concrete mixing is different. During paving, some gravel will accumulate in one piece, affecting the leveling effect. Moreover, during leveling, as the leveling mechanism moves, concrete will accumulate in front of the movement, affecting the movement and leveling of the leveling device, greatly slowing down the entire leveling efficiency.

[0029] like Figure 1-Figure 7As shown, the pushing unit on the mounting frame 4 includes a mounting plate 304, a support frame 307, a second hydraulic cylinder 311 and a pushing plate 315. A lifting assembly is installed on the mounting frame 4, the mounting plate 304 is movably installed on the lifting assembly, a scraper plate 5 and a buffer assembly are installed on the mounting plate 304, the support frame 307 is installed on the buffer assembly, a driving mechanism 308 is installed on the support frame 307, a roller 309 is rotatably installed on the support frame 307, the roller 309 is transmission-connected to the driving mechanism 308, a material-pusher tooth 310 is provided on the roller 309, and the second hydraulic cylinder 311 is installed on the mobile frame 1. The telescopic end of the second hydraulic cylinder 311 is equipped with a sliding frame 312, which is slidably connected to the mobile frame 1. An adjustment component is installed on the sliding frame 312, which is movably connected to the push plate 315. The driving mechanism 308, the second hydraulic cylinder 311 and the central control mechanism 7 are electrically connected. The driving mechanism 308 and the second hydraulic cylinder 311 work using existing technology. According to the direction of movement of the mobile frame 1 during leveling, the tilt direction of the push plate 315 is adjusted by the adjustment component, so that the material can move to the unleveled position when the push plate 315 pushes the material, and the sliding frame 312 is driven by the second hydraulic cylinder 311 The sliding frame 312 drives the push plate 315 to move through the adjusting component, so that the push plate 315 drops to a certain height, and drives the mounting plate 304 to move up and down through the lifting component, and drives the scraping plate 5 to move through the mounting plate 304, and adjusts the height of the scraping plate 5. The lifting component adjusts the two ends of the mounting plate 304 to different heights, thereby adjusting the horizontality of the scraping plate 5. The push plate 315 is higher than the scraping plate 5, and there is a certain height difference between the push plate 315 and the scraping plate 5. The moving frame 1 drives the push plate 315 and the scraping plate 5 to move, and the push plate 315 is used to adjust the height of the scraping plate 5. The concrete laid on the ground is pushed to reduce the accumulation of concrete and avoid the concrete accumulation height being too high. The scraper plate 5 is moved and scraped to pre-treat the surface of the concrete. The driving mechanism 308 drives the roller 309 and the stripping tooth 310 to rotate. The roller 309 and the stripping tooth 310 are used to strip and squeeze the concrete so that the stones on the surface enter the concrete, avoiding the accumulation of stones affecting the movement and scraping quality of the scraper plate 5, making the concrete flow and reducing the gaps in the concrete. The treated concrete surface is scraped and leveled by the scraper, effectively improving the quality and efficiency of leveling.

[0030] like Figure 1-Figure 3As shown, the lifting assembly on the mounting frame 4 includes a first hydraulic cylinder 301 and a first connecting seat 303. The first hydraulic cylinder 301 is installed on the mounting frame 4. A movable block 302 is installed on the telescopic end of the first hydraulic cylinder 301. The first connecting seat 303 is installed on the mounting plate 304. The first connecting seat 303 is rotatably connected to the movable block 302. The first hydraulic cylinder 301 and the central control mechanism 7 are electrically connected. The first hydraulic cylinder 301 works using existing technology. The movable block 302 and the first connecting seat 303 make the first hydraulic cylinder 301 and the mounting plate 304 movably connected. The first hydraulic cylinder 301 drives the mounting plate 304 to move through the movable block 302 and the first connecting seat 303, thereby adjusting the height and tilt angle of the mounting plate 304.

[0031] like Figure 2 As shown, the buffer assembly on the mounting plate 304 includes a damping rod 305, which is mounted on the lower surface of the mounting plate 304, and the telescopic end of the damping rod 305 is connected to the support frame 307. A spring 306 is sleeved on the damping rod 305, and the damping rod 305 and the spring 306 enable the support frame 307 to move up and down, which can form a certain buffer protection for the roller 309 and the material-digging tooth 310. The damping rod 305 and the spring 306 push the roller 309 and the material-digging tooth 310 through the support frame 307. The roller 309 and the material-digging tooth 310 can better press the stones on the concrete surface into the concrete, thereby preventing the surface concrete from affecting the leveling effect when paving the ground.

[0032] like Figure 1 、 Figure 3 、 Figure 5-Figure 7 The lever 314 is pivoted with the lever 314 to move upwards to unlock the lock member 312, so that the lock member 312 can be unlocked if necessary.

[0033] like Figure 2 、 Figure 4As shown, the monitoring unit on the mobile frame 1 includes a level sensor 9 and a laser 10. The level sensor 9 is arranged on the mounting plate 304, and the laser 10 is arranged at the upper end of the scraping plate 5. The level sensor 9 and the laser 10 are electrically connected to the central control mechanism 7. The level sensor 9 and the laser 10 work using existing technology. The horizontal state of the mounting plate 304 is detected by the level sensor 9, which facilitates the adjustment of the horizontal state of the mounting plate 304, so that the lower surface of the scraping plate 5 remains horizontal, and the leveling process can be better performed. During the leveling process, the laser 10 is compared with the external positioning mechanism to determine the leveling height. During the leveling process, the height of the scraping plate 5 is monitored in real time. When the height of the mobile frame 1 changes, the height of the scraping plate 5 can be adjusted in time to ensure the height of the scraping plate 5 and improve the quality of the scraping plate 5 leveling the ground.

[0034] like Figure 1 、 Figure 3 As shown, a battery 8 is installed on the mobile frame 1, and the battery 8 is electrically connected to the control switch group 2. The battery 8 adopts the existing technology. When the floor of some rooms where it is inconvenient to set up wires is leveled, the battery 8 provides power for the entire mechanism, thereby improving convenience.

[0035] like Figure 1 、 Figure 2 As shown, a vibration motor 6 is installed on the support frame 307, and the vibration motor 6 is electrically connected to the control switch group 2. The vibration motor 6 operates using existing technology. The support frame 307 is vibrated by the vibration motor 6, so that the roller 309 and the material-selecting teeth 310 can vibrate the concrete when stirring the concrete laid on the ground, thereby increasing the fluidity of the concrete, making it easier for the roller 309 and the material-selecting teeth 310 to select the concrete and the stones in the concrete, reducing the accumulation of the concrete and the stones in the concrete, and facilitating better scraping of the scraper plate 5.

[0036] Working principle: When leveling the concrete on the floor of a room, Figure 1 、 Figure 3 、 Figure 5-Figure 7 As shown, according to the direction of movement of the movable frame 1 during leveling, the screw 313 is rotated, and the screw 313 drives the push plate 315 to move through the second connecting seat 314, and the tilt direction of the push plate 315 is adjusted so that the material can move to the unleveled position when the push plate 315 pushes the material;

[0037] According to the thickness of the concrete, a positioning mechanism with a positioning height is set in the leveling room, such as Figure 2 、 Figure 4 As shown, the height of the scraping plate 5 is determined by comparing the laser 10 with the external positioning mechanism, as shown in FIG. Figure 1-Figure 3As shown, the first hydraulic cylinder 301 drives the mounting plate 304 to move through the movable block 302 and the first connecting seat 303 to adjust the height of the scraping plate 5. Figure 4 As shown, the horizontal state of the mounting plate 304 is detected by the level sensor 9, and the two ends of the mounting plate 304 are raised and lowered to different heights by the first hydraulic cylinder 301, thereby adjusting the levelness of the scraping plate 5;

[0038] like Figure 1 、 Figure 3 、 Figure 5 As shown, the second hydraulic cylinder 311 drives the sliding frame 312 to move, and the sliding frame 312 drives the push plate 315 to move through the screw 313, so that the push plate 315 drops to a certain height;

[0039] like Figure 1 、 Figure 3 、 Figure 5 As shown, the mobile frame 1 drives the push plate 315 and the scraper plate 5 to move, and the push plate 315 pushes the concrete accumulated during the paving of the ground to reduce the height of the concrete accumulation. The driving mechanism 308 drives the roller 309 and the material-digging tooth 310 to rotate, and the roller 309 and the material-digging tooth 310 dig and squeeze the concrete. At the same time, Figure 1 、 Figure 2 As shown, the support frame 307 is vibrated by the vibration motor 6, and the support frame 307 is moved up and down by the damping rod 305 and the spring 306, so that the roller 309 and the material-dispensing tooth 310 can dispense the concrete and vibrate it at the same time, so as to facilitate the dispersion of the accumulated concrete and allow the gravel to be dispersed into the concrete, and the treated concrete surface is smoothed by the scraper;

[0040] During the leveling process, if Figure 2 、 Figure 4 As shown, the height of the scraper plate 5 is constantly monitored by comparing it with an external positioning mechanism through the laser 10. When the height of the mobile frame 1 changes, the height of the scraper plate 5 can be adjusted in time through the first hydraulic cylinder 301 to ensure the quality of leveling.
