Description

Technical Field

[0001] This application relates to the field of photovoltaic foundation engineering construction equipment technology, and in particular to a ramming tool for photovoltaic support micro-hole grouting pile engineering construction. Background Technology

[0002] During the ramming process of bored piles, the foundation of the construction project is inspected beforehand to ensure that it meets relevant specifications and design requirements. During construction, ramming tools are used to compact the foundation, thereby determining the effective bearing capacity and preventing the presence of loose soil within the borehole. Currently, most drilling and ramming tools on the market are one-piece units, making it difficult to adjust the ramming head. This creates limitations when ramming different borehole diameters, necessitating the replacement of the entire unit. For different borehole diameters and depths, multiple units of the same tool must be carried. Utility Model Content

[0003] To address or partially address the problems existing in related technologies, this application provides a ramming tool for photovoltaic support micro-hole cast-in-place pile engineering construction, which is easy to assemble and carry and transport.

[0004] This application discloses a soil tamping tool for the construction of micro-hole cast-in-place piles for photovoltaic supports, comprising: a tamping head, a cylindrical rod, and a rotating handle; wherein the tamping head and the cylindrical rod are detachably connected, and the rotating handle is detachably connected to the cylindrical rod.

[0005] Optionally, a connecting rod is fixedly connected to the rammed earth head, and the cylindrical rod is threadedly connected to the connecting rod.

[0006] Optionally, the rotary handle is integrated with the cylindrical rod.

[0007] Optionally, the ramming head has a head threaded hole at its center, the rotating handle has a center threaded hole at its center, and the cylindrical rod has threaded heads at both ends, with one threaded head threaded to the head threaded hole and the other threaded head threaded to the center threaded hole.

[0008] Optionally, a limiting platform and a limiting groove are provided at the threaded hole of the rammed earth head, with the platform surface flush with the bottom of the limiting groove.

[0009] Optionally, a slide cylinder is slidably connected to the bottom of the cylindrical rod. The bottom of the slide cylinder is provided with a positioning plate that is compatible with the limiting platform. The side edge of the positioning plate is provided with an outer limiting key that is compatible with the limiting groove. A keyway is provided at the threaded end of the bottom of the cylindrical rod, and an inner limiting key that is compatible with the keyway is provided on the inner side of the slide cylinder.

[0010] The technical solution provided in this application may include the following beneficial effects:

[0011] This device features detachable connections for its components, allowing for the replacement of ramming heads and cylindrical rods of different sizes and lengths to accommodate micro-pores of varying diameters and depths. Simultaneously, a sliding cylinder restricts the rotation between the ramming head and the cylindrical rod, preventing over-tightening or loosening of the bottom threaded connection during construction.

While embodiments of this application are shown in the drawings, it should be understood that this application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to make this application more thorough and complete, and to fully convey the scope of this application to those skilled in the art.

[0024] It should be understood that although the terms "first," "second," "third," etc., may be used in this application to describe various information, this information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this application, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0025] In the description of this application, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not 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 application.

[0026] Unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0027] To address the aforementioned issues, this application provides a ramming tool for the construction of micro-hole cast-in-place piles for photovoltaic support systems. The technical solution of this application embodiment is described in detail below with reference to the accompanying drawings.

[0028] like Figure 1 The invention shown is a soil tamping tool for the construction of micro-hole cast-in-place piles for photovoltaic support, including a tamping head 1, a cylindrical rod 3, and a rotating handle 4; wherein the tamping head 1 and the cylindrical rod 3 are detachably connected by threads, and the rotating handle 4 is detachably connected to the cylindrical rod 3 by threads.

[0029] In this way, different sizes and lengths of ramming heads 1 and cylindrical rods 3 can be replaced according to specific needs to adapt to micro-pore ramming of different hole diameters and depths. At the same time, all parts can be disassembled for easy storage and transportation.

[0030] In one embodiment, such as Figure 2 As shown, in order to facilitate the hand-holding of the ramming head 1, a connecting rod 2 is fixedly connected to the ramming head 1, and a cylindrical rod 3 is threadedly connected to the connecting rod 2.

[0031] In one embodiment, the rotary handle 4 is integrally connected to the cylindrical rod 3.

[0032] In one embodiment, such as Figure 3 and Figure 4 As shown, since the ramming head 1 and the cylindrical rod 3 are connected by a threaded detachable connection, rotation during construction can cause the threads to loosen and become trapped inside the hole, making it difficult to detect in time. Therefore, a head threaded hole 11 is provided at the center of the ramming head 1, a center threaded hole is provided at the center of the rotating handle 4, and threaded heads 31 are provided at both ends of the cylindrical rod 3. One threaded head 31 is threaded to the head threaded hole 11, and the other threaded head 31 is threaded to the center threaded hole. At the same time, a limiting platform 12 and a limiting groove 13 are provided at the head threaded hole 11 of the ramming head 1. The platform surface of the limiting platform 12 is flush with the bottom of the limiting groove 13. Then, a slide cylinder 5 is slidably installed at the bottom of the cylindrical rod 3. A positioning plate 51 adapted to the limiting platform 12 is installed at the bottom of the slide cylinder 5. Only an outer limiting key 52 adapted to the limiting groove 13 is provided on the side edge of the positioning plate 51. A keyway 32 is provided at the bottom thread head 31 of the cylindrical rod 3. An inner limiting key 53 adapted to the keyway 32 is provided on the inner side of the slide cylinder 5.

[0033] Thus, when threading the rammed head 1 and the cylindrical rod 3, a sliding cylinder 5 is first fitted onto the cylindrical rod 3. After the cylindrical rod 3 and the rammed head 1 are threaded and tightened, the outer limit key 52 is aligned with the limit groove 13. The sliding cylinder 5 is slid, causing the positioning plate 51 to be embedded in the limit platform 12. At the same time, the outer limit key 52 is released and embedded in the limit groove 13. In this way, the inner limit key 53 of the sliding cylinder 5 locks the keyway 32, and the outer limit key 52 locks the limit groove 13, thereby preventing the cylindrical rod 3 and the rammed head 1 from rotating relative to each other, thus avoiding over-tightening or loosening of the bottom threaded connection during construction.

[0034] Finally, it should be noted that in this document, relationships such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "include," "contain," or any other variations are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.

[0035] The units described as separate components may or may not be physically separate. The components shown as units may or may not be physical units; that is, they may be located in one place or distributed across multiple network units. Some or all of the units can be selected to achieve the purpose of this embodiment according to actual needs.

[0036] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
