Description

Technical Field

[0001] This utility model belongs to the technical field of municipal engineering construction tools, and relates to small-volume filling construction tools in various narrow terrain spaces, especially a handheld compaction tool. Background Technology

[0002] Ramming refers to strengthening the foundation and is commonly used in the construction industry. It involves repeatedly dropping heavy objects onto the ground or filling materials to compact the soil and rock, thereby increasing their density.

[0003] In municipal engineering and building construction, the corner areas around sewage pipe networks and inspection wells are difficult to effectively construct due to their small space and irregular shape. Traditional large compaction machinery is difficult to use.

[0004] Currently, manual compaction is the most common method for compaction. However, ordinary compaction tools are not heavy enough, and homemade tampers cannot be adjusted according to different groups of people, design requirements, and terrain, resulting in inconvenience in operation. This leads to poor compaction effect and low work efficiency in small-volume filling construction in narrow terrain spaces such as corners.

[0005] Therefore, there is an urgent need for a handheld compaction tool specifically designed for irregularly shaped corner areas. Summary of the Invention

[0023] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0024] Please see Figure 1 It should be understood that the structures, proportions, sizes, etc., illustrated in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the disclosed technical content. Furthermore, the terms "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0025] Please see Figure 1 This utility model provides a handheld compaction tool, including a compaction plate 1. A connecting seat 2 is detachably connected to the compaction plate 1. At least two parallel threaded rods 9 are fixedly connected to the middle of the connecting seat 2. Several counterweights 3 can be fitted onto the threaded rods 9. After the threaded rods 9 pass through the counterweights 3, the counterweights 3 are fixed by bolts 4. This ensures that the counterweight can be increased or decreased according to different terrains and the physical strength of the user. This satisfies the need for adjusting the compaction weight without causing a load on the worker, thus ensuring the safety of the worker during operation.

[0026] Meanwhile, since workers of different heights require different handle heights, a height adjustment component is provided between the tamping plate 1 and the handle 8 in this embodiment. The height of the handle 8 can be adjusted according to the different heights of the workers, thereby increasing the applicability of the handheld tamping tool.

[0027] In this embodiment, the tamping plate 1 is made of 8mm thick Q235 steel plate, with dimensions of 250mm × 150mm, and a rounded corner with a radius of R = 50mm on one long side. The bottom surface of the tamping plate 1 is either flat or slightly convex.

[0028] In this embodiment, the handle 8 has a T-shaped or D-shaped structure. The surface of the handle 8 is covered with an anti-slip rubber sleeve, or the surface of the handle 8 is provided with anti-slip textures to increase the friction between the worker's hand and the handle 8, thereby further improving construction safety.

[0029] As a further description of the above embodiment, the connecting seat 2 includes two inclined first reinforcing connecting plates 21, and the two first reinforcing connecting plates 21 are connected and fixed together by a second reinforcing connecting plate 22 to form a trapezoidal structure or a triangular structure.

[0030] In this embodiment, the two first reinforcing connecting plates 21 are inclined and form a trapezoidal or triangular structure with the second reinforcing connecting plate 22. This can enhance the structural strength while ensuring that the first reinforcing connecting plate 21 and the ramming plate 1 form a triangular structure, thereby ensuring and improving the stability of the connection between the connecting seat 2 and the ramming plate 1.

[0031] In this embodiment, in order to facilitate a detachable connection between the first reinforcing connecting plate 21 and the tamping plate 1, a fixing plate 23 is fixedly connected to the lower end of the first reinforcing connecting plate 21. Threaded holes are opened at corresponding positions on the fixing plate 23 and the tamping plate 1. The fixing plate 23 and the tamping plate 1 are detachably connected by bolts 4, which facilitates the maintenance and replacement of the handheld tamping tool.

[0032] Of course, the connection between the connecting seat 2 and the ramming plate 1 is not limited to opening a hole in the ramming plate 1. When it is not convenient to open a hole in the ramming plate 1, a threaded rod can be welded and fixed on the ramming plate 1. A through hole can be opened on the fixing plate 23 at the position corresponding to the threaded rod. The threaded rod can pass through the through hole and then be connected and fixed by bolts 4.

[0033] In this embodiment, the first reinforcing connecting plate 21 and the fixing plate 23, and the first reinforcing connecting plate 21 and the second reinforcing connecting plate 22 are integrally formed to ensure the integrity and stability of the connecting seat 2.

[0034] In this embodiment, in order to ensure that the connecting seat 2 can accommodate multiple counterweights 3, the counterweights 3 are set as trapezoidal structures similar to the connecting seat 2, and the bottom edges of the multiple counterweights 3 decrease sequentially from bottom to top.

[0035] In this embodiment, the shape of the connecting seat 2 is not limited to a trapezoid. Other structures that can maintain the strength of the connecting seat 2 and can be stably connected with the ramming plate 1 are also acceptable, such as forming a square structure between the connecting seat 2 and the ramming plate 1.

[0036] Of course, the counterweight 3 is not limited to being installed inside the connecting seat 2. When a larger counterweight is required, threaded rods (not shown in the figure) can be symmetrically fixed on the upper surface of the ramming plate 1 between the side wall of the connecting seat 2 and the side wall of the ramming plate 1, and counterweights 3 can be symmetrically installed on the threaded rods.

[0037] As a further description of the above embodiment, the height adjustment assembly includes a base connecting rod 5, the bottom of which is welded and fixedly connected to the connecting seat 2. The upper end of the base connecting rod 5 has an internal thread and is threadedly connected to a height adjustment rod 6. The bottom of the height adjustment rod 6 has an external thread that matches the internal thread of the base connecting rod 5. The top of the height adjustment rod 6 has an internal thread and is threadedly connected to an upper connecting rod 7. The bottom of the upper connecting rod 7 has an external thread that matches the internal thread of the height adjustment rod 6. The top of the upper connecting rod 7 is fixedly connected to a handle 8.

[0038] In this embodiment, a number of height adjustment rods 6 are connected between the base connecting rod 5 and the upper connecting rod 7 by threaded splicing of female sleeves in pairs. This allows for the addition or reduction of the number of height adjustment rods 6 as needed, thereby adjusting the height of the handle 8 to meet different usage requirements.

[0039] Of course, the height adjustment component is not limited to this structure; other structures capable of adjusting the height of the handle 8 are also acceptable. For example, an electric telescopic rod or a pneumatic telescopic rod can be fixedly connected to the upper surface of the second reinforcing connecting plate 22, with the output end of the electric telescopic rod or the pneumatic telescopic rod fixedly connected to the handle 8.

[0040] In this embodiment, the base connecting rod 5, the height adjusting rod 6, and the upper connecting rod 7 are all hollow steel pipes with an outer diameter of 40-60mm and a wall thickness of 3-5mm.

[0041] In summary, the working principle of a handheld compactor is as follows:

[0042] In use, the operator holds handle 8, aligns the tamping plate 1 with the area to be compacted, and performs the compaction operation by manually lifting and lowering it. The counterweight 3 provides sufficient compaction force, and the height adjustment component can adjust the tool length according to the operator's height to ensure operational comfort. At the same time, depending on the compaction thickness and the area of ​​influence, additional configurations and extensions of handle 8 can be added to enable two-person operation and improve construction efficiency.

[0043] In summary, this invention allows for adjustable handle height to accommodate users of different heights, facilitating operation. Furthermore, the counterweight design allows for increased compaction weight to meet varying needs, thereby improving compaction effectiveness and work efficiency in corner areas. Therefore, this invention effectively overcomes the shortcomings of existing technologies and possesses significant industrial application value.

[0044] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
