Description

Technical Field

[0001] This utility model relates to the field of civil engineering construction technology, specifically to a cement leveling device for civil engineering construction. Background Technology

[0002] Civil engineering construction refers to the process of transforming civil engineering design drawings into actual engineering entities using various building materials, construction equipment, and construction techniques, according to design requirements. Cement trowels are one such piece of equipment used in construction. Currently, cement trowels used in construction are operated manually, with a motor driving the trowel disc to rotate and smooth the cement surface. There are no safety measures during the rotating operation, posing a safety hazard. After use, the trowel disc directly contacts the ground, ensuring the stability of the entire device. Human error can easily cause the trowel disc to directly impact the ground, resulting in damage and increased subsequent maintenance costs. Summary of the Invention

[0003] The main objective of this invention is to provide a cement leveling device for civil engineering construction, which aims to solve at least one of the technical problems existing in the background art.

[0004] Therefore, the present invention provides a cement leveling device for civil engineering construction, including a cement leveling machine. The cement leveling machine includes a frame and a leveling disc disposed at the bottom of the frame. The frame is equipped with a drive motor for driving the leveling disc to rotate. The frame is also equipped with a hand handle. An annular protective frame is fitted around the leveling disc. The frame is equipped with a drive assembly for driving the annular protective frame to move up and down relative to the leveling disc. When the drive assembly drives the annular protective frame to move downward and contact the ground, the leveling disc is lifted off the ground.

[0005] Specifically, the bottom of the annular protective frame is evenly provided with multiple movable rollers.

[0006] Specifically, the drive assembly includes at least two push cylinders arranged circumferentially along the annular guard frame, with one end of each push cylinder connected to the frame and the other end connected to the annular guard frame.

[0007] Compared with existing technologies, this invention has the following advantages: When smoothing a cement surface, the entire device is first placed on the surface. Then, the drive assembly moves the annular guard frame upwards, detaching it from the cement surface while the trowel plate contacts it. The drive motor is then activated to rotate the trowel plate. Holding the handle firmly, the device is pushed across the cement surface to smooth the cement. The annular guard frame provides protection during the process, ensuring operational safety. After the cement surface work is completed, the drive assembly moves the annular guard frame downwards until it contacts the ground, lifting the trowel plate off the ground. Even if there is a mis-start, the trowel plate will only spin idle and will not cause damage. Attached Figure Description

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0014] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0015] See Figure 1 and Figure 2 A cement smoothing device for civil engineering construction includes a cement smoothing machine. The cement smoothing machine is an existing structure. The cement smoothing machine mainly includes a frame 1 and a smoothing disc 2 set at the bottom of the frame 1. The frame 1 is equipped with a drive motor 3 that drives the smoothing disc 2 to rotate. The frame 1 is equipped with a hand push handle 4. The smoothing disc 2 is surrounded by an annular protective frame 5. The frame 1 is equipped with a drive component 6 that drives the annular protective frame 5 to move up and down relative to the smoothing disc 2. When the drive component 6 drives the annular protective frame 5 to move downward and contact the ground, the smoothing disc 2 is lifted off the ground.

[0016] The working process of the above-mentioned cement smoothing device is as follows: When smoothing the cement surface to be cured, first place the entire device on the cement surface to be smoothed. Then, use the drive component 6 to move the annular guard frame 5 upward, so that the annular guard frame 5 is detached from the cement surface, while the trowel 2 contacts the cement surface. Then, start the drive motor 3 to drive the trowel 2 to rotate. Grip the hand handle 4 and push the device to move on the cement surface to achieve cement smoothing. At the same time, the annular guard frame 5 provides protection during the process to ensure operational safety. After the cement surface work is completed, the drive component 6 moves the annular guard frame 5 downward to contact the ground, thereby lifting the trowel 2 off the ground. Even if there is a problem of accidental start, the trowel 2 will only spin idle and will not cause damage.

[0017] See Figure 1It is understandable that, to facilitate the movement of the entire device, multiple moving rollers 7 are evenly provided at the bottom of the annular protective frame 5. When moving the cement trowel, it is only necessary to use the drive component 6 to drive the entire annular protective frame 5 downward, so that the rollers contact the ground, while the trowel disc 2 is continuously raised, so that it is lifted off the ground. At this time, the cement trowel can be moved to a specified position by the rolling of the moving rollers 7 with the ground.

[0018] See Figure 1 and Figure 2 Specifically, the drive assembly 6 includes two push cylinders 8 evenly arranged along the circumference of the annular guard frame 5. One end of the push cylinder 8 is fixedly connected to the frame 1, and the other end is fixedly connected to the annular guard frame 5. The push cylinder 8 drives the annular guard frame 5 to move up and down. Of course, the number of push cylinders 8 can also be three or even more.

[0019] Unless otherwise stated, if any of the technical solutions disclosed in this utility model discloses a numerical range, then the disclosed numerical range is a preferred numerical range. Anyone skilled in the art should understand that the preferred numerical range is merely one among many feasible numerical values ​​that has a more obvious or representative technical effect. Because there are many numerical values, it is impossible to list them all. Therefore, this utility model discloses only some numerical values ​​to illustrate the technical solutions of the invention. Furthermore, the numerical values ​​listed above should not constitute a limitation on the scope of protection of this invention.

[0020] Meanwhile, if the present invention discloses or relates to mutually fixedly connected parts or structural components, then unless otherwise stated, the fixed connection can be understood as: a detachable fixed connection (e.g., using bolts or screws), or a non-detachable fixed connection (e.g., riveting, welding). Of course, mutually fixed connections can also be replaced by an integral structure (e.g., manufactured by casting) (except where it is obviously impossible to use an integral forming process).
