Description

Technical Field

[0001] This invention relates to the field of building construction equipment technology, specifically to a rapid surface finishing device for highly flat concrete floors. Background Technology

[0002] Existing finishing devices for concrete surfaces have limited applicability and are inconvenient to adjust. A rapid finishing device for high-flatness concrete floors, as described in application number 2020212949456, includes a moving mechanism. The moving mechanism comprises a bearing plate, a support column, casters, a counterweight, a fixing frame, and handles. It can adjust the height of the finishing position, and with the help of two handles, the operator can maintain a more suitable standing position for operation. It can be applied to more complex concrete surfaces, increasing the machine's applicability.

[0003] Although this device overcomes the shortcomings of existing technologies, it still has the following drawbacks:

[0004] 1) When the surface finishing block of this device is used to finish the cement floor, its fixed size and position result in a small finishing range. In the process of large-area processing, it is necessary to repeatedly adjust the position to finish the surface, which is not only time-consuming and labor-intensive, but also results in low finishing efficiency.

[0005] 2) The device uses counterweights to maintain balance, but this increases the weight of the device. It is also moved by manual support, which not only results in low moving efficiency but also unstable moving speed, affecting the leveling effect on the cement floor.

[0006] 3) The device moves by contacting the ground with casters. On the one hand, the small contact area makes it difficult to move, and on the other hand, the device is unbalanced, which reduces the leveling effect on the cement floor.

[0007] Therefore, it is necessary to address the aforementioned problems. Summary of the Invention

[0017] Beneficial effects

[0018] This invention provides a rapid surface finishing device for highly smooth concrete floors. Compared with existing technologies, it has the following advantages:

[0019] (1) By setting up a balancing mechanism, the laser level is used to fix the fixed plate on both sides of the cement floor so that the supporting base on both sides is kept horizontal and at the same height. At the same time, by using the property of the roly-poly toy, the connecting rod keeps the supporting plates on both sides at the same horizontal height, ensuring the horizontality of the movement trajectory, thereby improving the flatness of the cement floor surface.

[0020] (2) By setting a locking component, after the tumbler drives the two side support plates to level, the screw drives the cylinder to move through the connecting plate. Through the connection between the ball groove and the ball, the rotating rod is locked, which improves the stability of the support plate and thus ensures the smoothness when finishing.

[0021] (3) By setting up the walking components, the connection between the two side slides and the horizontal plate, the connection between the ball and the arc groove, and the connection between the walking gear and the tooth groove, the stability during the dough collection is further improved. At the same time, by utilizing the rotation of the walking gear and the meshing between the teeth, the device can automatically move at a uniform speed, thereby improving the efficiency and effect of the dough collection.

[0022] (4) By setting up a leveling unit, the extension and retraction properties of the push-pull rod and the lifting rod can be used to adjust the position of the trowel in the vertical plane in both the longitudinal and transverse directions, thereby improving the leveling range and efficiency. At the same time, by using the rotation of the rotary cylinder, the trowel can be rotated vertically, which can change the leveling direction of the horizontal plane, thereby improving the flatness of the leveling.

[0023] (5) By setting a fixed module, utilizing the telescopic properties of the lifting rod and spring rod, and connecting the clip with the through groove and the bracket, the trowel and the traction plate can be divided into two parts and can be combined into one, thus facilitating the leveling treatment of cement floors with different solidification degrees, thereby improving the application range of the device.

[0044] Example 6: This example combines Examples 1 to 5. By leveling the surface movement trajectory, the efficiency and effect of leveling the cement floor surface are improved. At the same time, by adjusting the leveling position through extension and retraction, the leveling range is increased, thereby further improving the efficiency of surface leveling.

[0045] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0046] During operation, firstly, the two fixed plates 2 are fixed to the supports on both sides of the cement floor using bolts or other fasteners. Simultaneously, a laser level is used to ensure the two fixed plates 2 are on the same horizontal line. Adjustment is made using external padding or adjustable components to ensure the two fixed frames 3 are on the same horizontal line. Then, utilizing the properties of the self-righting toy 8, the connecting rod 9 keeps the two support plates 6 at the same height. Subsequently, the output end of the tension rod 13 retracts, causing the arc plate 12 to contact the inner wall of the annular groove 11, thus initially fixing the rotating rod 4. Next, the traction motor 57 drives the lead screw 56 to rotate, and through the threaded connection between the lead screw 56 and the connecting plate 51, the connecting plate 51 moves the cylinder 52 closer to the sphere. 54. Thus, through the connection of the ball groove 53 and the ball 54, the rotating rod 4 is locked to improve the stability of the support plate 6. Then, the horizontal plate 71 is fixed to the support plate 6 with bolts. Then, the box body 1 is connected to the horizontal plate 71 through the connection of the slide 73 to the horizontal plate 71, the connection of the ball 75 to the arc groove 76, and the connection of the traveling gear 78 to the residual tooth groove 77, thus ensuring the stability of the box body 1 and the trowel 723. After the concrete floor is poured, the output ends of the push-pull rod 721 and the lifting rod 726 extend and retract, so that the trowel 723 comes into contact with the wet and soft concrete. At the same time, the vibrator 729 makes the trowel 723 vibrate, so that the concrete can automatically flow for initial leveling. Meanwhile, the spring rod 728 buffers vibrations, preventing loosening of the connection between the housing 1 and the fixed plate 2. In conjunction with the travel motor 710 driving the travel gear 78, the housing 1 extends and retracts along one end of the horizontal plate 71 and the output end of the push-pull rod 721, thus initially leveling the entire cement floor. When the cement floor is semi-solidified, the lifting rod 726 fully compresses the spring rod 728, causing the locking strip 7243 to pass through the through groove 7242. Then, the drive motor 7248 drives the drive gear 7247 to rotate, causing the rotating gear 7246 to drive the vertical rod 7244 to rotate, thus making the locking strip 7243 perpendicular to the through groove 7242. Simultaneously, the locking strip 7243 and the bracket 724... 1. A snap-fit ​​mechanism is formed, making the trowel 723 and the traction plate 727 a single unit. Then, the lifting rod 726 and the output end of the push-pull rod 721 extend and retract, causing the trowel 723 to contact the cement floor surface again. Simultaneously, the rotation of the travel gear 78 causes the trowel 723 to move laterally on the horizontal plane. At the front end of the movement, cement powder or cement slurry inside the housing 1 is sprinkled onto the cement floor surface, enhancing the finishing efficiency and effect. After the overall horizontal finishing is completed, the rotary cylinder 725 drives the trowel 723 to rotate vertically. Then, in conjunction with the extension and retraction of the output end of the push-pull rod 721 and the movement of the travel gear 78, the trowel 723 performs longitudinal finishing on the horizontal plane, thereby improving the flatness of the finished surface.
