Description

Technical Field

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

[0002] The ground leveling device for concrete construction is a machine for rough and fine finishing of concrete surfaces. The surface constructed by the machine is smoother and flatter than the surface constructed by humans. It can greatly improve the density and wear resistance of the concrete surface, and improve work efficiency by more than 10 times compared with manual operation.

[0003] However, the floor leveling devices used in concrete construction are usually large in size and have a wide coverage area when working. If they encounter corners or narrow spaces, the concrete construction leveling devices have no way to handle these places. Their large size and bulky structure limit the flexibility of operation in narrow areas, resulting in low work efficiency. They may even be unable to enter certain restricted spaces for construction and need to wait for manual leveling. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

The screw thread 7 is provided with a screw thread 8 and a screw thread 9. The screw thread 7 is provided with a screw thread 8 and a screw thread 9. The screw thread 7 is provided with a screw thread 8 and a screw thread 9.

[0038] In this embodiment, the main smoothing mechanism includes a motor 101, a rotating plate 102 and a main scraper 103. The motor 101 is fixedly mounted on the inner top wall of the safety cover 5, the rotating plate 102 is fixedly connected to the output end of the motor 101, and the main scraper 103 is fixedly connected to the rotating plate 102. In addition, the bottom of the main scraper 103 and the auxiliary scraper 7 are both set to an arc-shaped surface 9. The arc-shaped surface 9 scraper can reduce the impact and friction on the ground surface during operation, thereby improving the quality after smoothing and reducing intermittent and unremovable scratches that occur during the smoothing operation.

[0039] In this embodiment, the folding mechanism includes two fixed columns 201, a sliding ring 202, a fixed rod 203, a rotating port 1 204, a sliding rod 205 and a rotating port 2 206. The two fixed columns 201 are respectively fixedly connected to the top of the main scraper 103 away from the auxiliary scraper 7 on both sides. The two fixed columns 201 are slidably connected to the sliding ring 202. The outer side wall of each sliding ring 202 away from the safety cover 5 is spirally connected to the fixed rod 203. Each sliding ring 202 is away from the fixed Rotating openings 204 are symmetrically provided on the outer walls at both ends of the rod 203, and one end of a sliding rod 205 is hinged to each rotating opening 204. A rotating opening 206 is provided on the rotating shaft 8, and the other end of each sliding rod 205 is hinged to the rotating opening 206. A limiting plate 10 is provided on the top of the fixed column 201, which is used to limit the sliding range of the sliding ring 202 when the sliding ring 202 slides upward, so as to prevent the sliding ring 202 from sliding directly out of the fixed column 201.

[0040] To sum up, the working principle of the ground leveling device for concrete construction is as follows: when leveling the concrete construction surface, first determine the leveling motion trajectory, start the motor 101, and make the motor 101 drive the main scraper 103 and the auxiliary scraper 7 to rotate and level. After leveling most of the area, turn off the motor 101, rotate and open the fixed rod 203, loosen the sliding ring 202 and slide it upward, and drive the sliding rod 205 to fold the auxiliary scraper 7 while sliding. After determining the position, tighten the fixed rod 203 to fix it, push the joystick 1 to perform micro-processing on the edges and scratches that have not been processed just now, rotate the joystick 1 to make the main scraper 103 slide longitudinally, and perform leveling operations on the narrower concrete construction area. When the leveling operation is relatively simple, the motor 101 can be omitted, and the joystick 1 can be directly pushed for simple leveling.

[0041] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
