Description

Technical Field

[0001] This utility model relates to the field of ground compaction, and more specifically, to a ground compaction device for building construction. Background Technology

[0002] Ground compaction in construction is a key process that uses external force to rearrange soil particles more compactly, reducing pore volume and thus improving the bearing capacity and stability of the foundation. The physical essence of compaction is to overcome the friction and cohesion between soil particles through dynamic methods such as impact, rolling, or vibration, forcing the particles to rearrange into a more compact position. As soil porosity decreases, the bearing characteristics of the foundation are significantly improved, manifested as increased bearing capacity, reduced compressibility, decreased permeability, and enhanced resistance to liquefaction. Commonly used compaction methods include traditional manual compaction (such as wooden and stone rammers), mechanical compaction (such as vibratory rammers and internal combustion rams), and the highly efficient dynamic compaction method (using the impact energy generated by the free fall of a heavy hammer to treat deep soil layers).

[0003] Traditional compaction devices are not equipped with wheels, requiring multiple people to carry them or other equipment for relocation, which significantly increases labor costs and reduces construction efficiency. In addition, they generate a lot of dust during use. Therefore, we have made improvements and proposed a ground compaction device for building construction. Utility Model Content

[0032] Example:

[0033] like Figure 1-6 As shown, this embodiment proposes a ground compaction device for building construction, including a mounting frame 1, a connecting frame 2 fixedly mounted at the bottom of the mounting frame 1, a mounting plate 3 fixedly mounted on the connecting frame 2, a motor 4 fixedly mounted at the top of the mounting plate 3, an eccentric wheel 5 fixedly mounted at the output end of the motor 4, the output end of the motor 4 drives the eccentric wheel 5 to rotate, a transmission rod 6 is rotatably connected to the eccentric wheel 5, and a compaction plate 7 is rotatably connected to the other end of the transmission rod 6. The rotational motion of the eccentric wheel 5 is converted into the reciprocating linear motion of the compaction plate 7 through the transmission rod 6, and a periodic impact force is generated by utilizing the eccentricity. The compaction plate 7 moves vertically up and down under the drive of the transmission rod 6, applying an impact force to the ground; a dust cover 8 is provided on the outer wall of the compaction plate 7, and the dust cover 8 covers the working area of ​​the compaction plate 7. During compaction, dust is confined within the hood and slowly released through the top gap, significantly reducing dust diffusion. A column 9 is fixedly installed on the top of the mounting frame 1, and an electric push rod 10 is fixedly installed inside the column 9. A movable plate 11 is fixedly installed at the output end of the electric push rod 10. The output end of the electric push rod 10 pushes the movable plate 11 downward. A connecting rod 12 is fixedly installed at the bottom of the movable plate 11. The movable plate 11 drives the connecting rod 12. A long plate 13 is fixedly installed at the bottom of the connecting rod 12. The connecting rod 12 drives the long plate 13. A brake caster 14 is fixedly installed at the bottom of the long plate 13. The long plate 13 drives the brake caster 14 downward. When the brake caster 14 contacts the ground, the device rises.

[0034] A washer 15 is fixedly installed at the bottom of the connecting frame 2, and an L-shaped rod 16 is fixedly installed at the top of the washer 15. The other end of the L-shaped rod 16 is fixedly connected to the dust cover 8. During the compaction process, the dust cover 8 is fixed to the washer 15 through the L-shaped rod 16, covering the working area of ​​the tamping plate 7. The dust generated during the tamping is confined inside the cover and slowly released through the top gap, greatly reducing the spread of dust.

[0035] A first guide rod 17 is fixedly installed on the top of the tamping plate 7. The first guide rod 17 is slidably connected to the dust cover 8. The first guide rod 17 passes through the dust cover 8 and is fixed to the tamping plate 7 to ensure that the movement trajectory is vertical during the tamping process and to prevent deviation.

[0036] A spring 18 is fixedly installed on the top of the ramming plate 7. The other end of the spring 18 is fixedly connected to the dust cover 8. The spring 18 connects the ramming plate 7 and the dust cover 8, and plays a role in buffering and resetting to avoid rigid collisions that could damage the components.

[0037] A second guide rod 19 is fixedly installed on the top of the mounting bracket 1. The second guide rod 19 is slidably connected to the movable plate 11. The movable plate 11 slides along the second guide rod 19. A battery box 26 is fixedly installed at the bottom of the mounting bracket 1. The battery box 26 supplies power to the electric push rod 10 and the motor 4.

[0038] An auxiliary plate 20 is fixedly installed on the top of the connecting frame 2. A sliding groove 21 is provided on the side wall of the auxiliary plate 20. An extension rod 22 is fixedly installed on the connecting rod 12. A slider 23 is fixedly installed on the extension rod 22. The extension rod 22 drives the slider 23 to slide along the sliding groove 21. The slider 23 matches the sliding groove 21.

[0039] A switch base 24 is fixedly installed on the top of the column 9. A switch is mounted on the switch base 24 to control the electric push rod 10 and the motor 4. A handle 25 is fixedly installed on the switch base 24.

[0040] Specifically, when the ground compaction device used in this construction project is moved while not in operation, the electric push rod 10 is activated. The output end of the electric push rod 10 pushes the moving plate 11 downward. The moving plate 11 slides along the second guide rod 19, which in turn drives the connecting rod 12. The connecting rod 12 drives the extension rod 22, which in turn drives the slider 23 to slide along the slide groove 21. At the same time, the connecting rod 12 drives the long plate 13, which in turn drives the brake caster 14 downward. When the brake caster 14 contacts the ground, the device rises. At this time, the washer 15 is not in contact with the ground. Figure 1 As shown: The wheels are in contact with the ground, and the device can be easily pushed. This device controls the raising and lowering of the moving wheels via an electric push rod 10, allowing for a switch from moving mode to compaction mode within seconds. When moving, the wheels are in contact with the ground, easily pushing the device; when working, the wheels are retracted to ensure compaction stability. This design solves the problem of traditional compactors requiring manual handling or relying on vibration for movement.

[0041] During operation, motor 4 is started, and the output end of motor 4 drives the eccentric wheel 5 to rotate. The rotational motion of the eccentric wheel 5 is converted into the reciprocating linear motion of the tamping plate 7 through the transmission rod 6. The two ends of the transmission rod 6 are hinged to the eccentric wheel 5 and the tamping plate 7 respectively. The eccentricity generates a periodic impact force. The tamping plate 7 moves vertically up and down under the drive of the transmission rod 6, applying impact force to the ground. The first guide rod 17 passes through the dust cover 8 and is fixed to the tamping plate 7 to ensure that the movement trajectory is vertical during the tamping process and to prevent deviation. The spring 18 connects the tamping plate 7 and the dust cover 8, which plays a role in buffering and resetting, and avoids rigid collisions that could damage the components. During the tamping process, the dust cover 8 is fixed to the washer 15 through the L-shaped rod 16, covering the working area of ​​the tamping plate 7. The dust generated during tamping is confined inside the cover and slowly released through the top gap, greatly reducing the spread of dust.

[0042] All technical features in this embodiment can be freely combined according to actual needs.

[0043] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
