Description
Technical Field
[0001] This application relates to the field of building construction, specifically to a rapid leveling device for concrete floors. Background Technology
[0002] As a crucial component of a building structure, the flatness of the basement's concrete floor directly impacts the overall quality of the building and subsequent construction processes. Floor leveling is a fundamental step in ensuring the installation of waterproofing layers, decorative finishes, and equipment in the basement. Insufficient flatness can lead to hollow areas in the materials, increased risk of leaks, and even affect the floor's load-bearing capacity and durability. Furthermore, modern basements are often used as parking lots, storage spaces, or functional areas; uneven floors significantly reduce user comfort and may cause safety hazards due to localized water accumulation or structural stress concentration. Therefore, concrete leveling is an indispensable and critical step in basement construction.
[0003] Current concrete leveling methods primarily rely on manual operation or semi-mechanized equipment. For small areas, construction workers often use tools such as screeds and rulers to manually level the concrete surface. For larger areas, laser screeds, vibratory beam pavers, or track-mounted pavers are used. Among these, small handheld or push-pull leveling devices are commonly used. These devices are typically held or pushed by the operator, achieving initial leveling of the concrete through mechanical vibration or scraper movement. During the operation, the position and angle of the equipment need to be repeatedly adjusted, and local depressions need to be repaired manually.
[0004] During the leveling process described above, operators inevitably step on uncured areas when using handheld or pushed leveling equipment. This causes the concrete to sink under pressure and even adhere to the base layer, forming secondary depressions, forcing rework and increasing the difficulty of controlling flatness. Secondly, concrete slurry easily splashes and adheres to the operator's shoes during operation, not only causing material loss and holes on the construction surface but also requiring frequent cleaning of shoe contamination, severely reducing construction efficiency. To improve the problems of ground deformation caused by trampling, concrete material loss, and low construction efficiency caused by traditional manual operation, this application provides a rapid leveling device for concrete floors.

Detailed Implementation
[0016] To make the technical means, innovative features, objectives and effects of this utility model easier to understand, the utility model will be further described below.
[0017] The embodiments described herein are specific implementations of this utility model, used to illustrate the concept of this utility model. They are all illustrative and exemplary, and should not be construed as limiting the implementation methods or scope of this utility model. In addition to the embodiments described herein, those skilled in the art can employ other obvious technical solutions based on the content disclosed in the claims and specification of this application. These technical solutions include those that make any obvious substitutions and modifications to the embodiments described herein.
[0018] Example 1 A rapid leveling device for concrete floors, such as Figures 1-4 As shown, the system includes a leveling frame 1, a power unit 2 and rollers 3 located in the middle of the leveling frame 1. The leveling frame 1 includes a central main support 11 and several L-shaped legs 12 located on the outer wall of the central main support 11. The horizontal part of the L-shaped legs 12 is fixed to the central main support 11, and the lower part of the vertical part is connected to the leveling frame 13. The leveling frame 13 is a rectangular frame structure. The cross-sectional area of the central main support 11 is smaller than the cross-sectional area of the leveling frame 13, and it is suspended directly above the middle of the leveling frame 13. The vertical part of the L-shaped legs 12 includes a buffer sleeve and a buffer rod. The rollers 3 include a U-shaped wheel frame 31 fixed to the bottom surface of the central main support 11 and a roller body 32 located between the two vertical parts of the U-shaped wheel frame 31. The roller body 32 includes a shaft and at least two rollers fixed on the shaft. The shaft and the two vertical parts of the U-shaped wheel frame 31 are rotatably connected by bearings.
[0019] Example 2 Based on Embodiment 1, the power unit 2 includes a steering power unit 21 and a walking power unit 22. The steering power unit 21 includes a servo motor 24 located on the top surface of the central main support 11. The output end of the servo motor 24 passes through the central main support 11 and is fixed to the top surface of the horizontal part of the U-shaped wheel frame 31. The walking power unit 22 includes a drive motor 25, a driving bevel gear 26, and a driven bevel gear 27. The driven bevel gear 27 is fixed to the end face of the shaft passing through the vertical part of the U-shaped wheel frame 31. The walking power unit 22 is fixed on the outer wall of the vertical part of the U-shaped wheel frame 31 and is provided with a protective cover 23 on the outside. A controller 4 for controlling the drive motor 25 and the servo motor 24 is also provided on the central main support 11.
[0020] The central main support 11 is a rectangular plate structure, the leveling frame 13 is a rectangular frame pile structure, and two L-shaped support legs 12 are set along one side of the frame. The rollers 2 should be set in two sets with a front-to-back spacing, including active rollers and passive rollers, and the steering power device 21 should be set on the active rollers.
[0021] Example 3 The vibratory leveling beam, with its frame structure, covers the area to be leveled. A drive mechanism autonomously moves the mounting frame, preventing operators from stepping on uncured concrete. A buffer structure isolates vibrations from the mounting frame, ensuring stable equipment operation. The control mechanism keeps operators away from the work area, completely eliminating the problem of shoes sticking to concrete. This solution directly addresses the pain points of secondary ground subsidence caused by manual walking, concrete slurry splashing and contamination, and low efficiency. Simultaneously, mechanized operation improves leveling accuracy and construction efficiency, reducing rework and material waste.
[0022] The local vibrations of the vibratory leveling beam are transmitted to the buffer sleeve through the buffer rod, where the energy is absorbed by the buffer spring, achieving multi-point synchronous vibration damping. This design ensures that the vibration energy is evenly distributed, avoiding the superposition of local vibrations that could lead to bracket misalignment or leveling beam deformation. It maintains the vibration compaction effect required for leveling operations while reducing the overall vibration amplitude of the equipment, extending the structural lifespan, and ensuring that the leveled concrete surface is free of undulations, thus improving the uniformity of the floor flatness.
[0023] The matching design of the connecting ear plate and mounting holes allows for adjustment of the installation height and angle of the buffer beam to accommodate leveling requirements for concrete layers of varying thicknesses. This structure gives the buffer structure modular characteristics, facilitating quick disassembly, maintenance, or replacement of damaged components. Simultaneously, multiple sets of mounting holes provide redundant fixing points, enhancing the equipment's adaptability to different operating conditions and reducing the risk of downtime due to buffer structure failure.
[0024] The rolling component can drive one of the support rollers to rotate, thereby enabling the leveling device to move, while the rotating component can drive this set of support rollers to turn, thereby enabling the leveling device to turn.
[0025] The power of the driving component is transmitted to the driven bevel gear via the active bevel gear, causing the support rollers to move at a constant speed. The rotating component independently controls the rotation of the rollers, enabling precise control of the equipment's forward, backward, and turning movements. This design replaces traditional manual push-pull operations, ensuring the linearity of the movement trajectory through mechanical transmission and avoiding path deviations caused by uneven manual force. Furthermore, the bevel gear transmission structure is compact and provides stable torque transmission, making it suitable for high-load conditions in concrete construction environments.
[0026] The control panel sends commands to the control system, which then interprets and controls the drive mechanism to start, stop, adjust speed, and steer. This design allows operators to complete all operations from a location far from the construction area, completely avoiding the problems of stepping on uncured ground and shoes sticking to concrete. At the same time, programmed commands reduce human error and improve the standardization of the construction process, making it particularly suitable for long-distance continuous operations in complex basement spaces.
[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
