Description

Technical Field

[0001] The utility model relates to the technical field of drilling, in particular to a drilling construction structure. Background Art

[0002] In civil engineering construction, drilling operations play a vital role, especially in key links such as foundation treatment and pile foundation construction. For a long time, the current drilling construction structure has generally adopted spiral drills. The spiral drill is widely used because of its simple structure and easy operation. The spiral drill uses its unique spiral-shaped drill bit to use cutting force during rotation to break up the underground soil or rock and bring it out of the soil layer. This principle meets the basic needs of foundation construction to a certain extent.

[0003] However, with the increasing complexity of the construction environment, the current drilling construction structure has gradually exposed its limitations. Especially in complex geological conditions such as strata containing pebbles, gravel or clay layers, the drilling efficiency and effect of the spiral drill are often greatly reduced. This is because the shape and force mode of the spiral drill bit increase its drilling resistance, making it difficult to discharge the soil. Especially when encountering hard strata, the drilling speed drops significantly, and may even cause serious wear and damage to the drill bit, increasing construction costs and safety risks.

[0004] Therefore, in view of this, the inventor proposes a drilling construction structure to solve the above technical problems. Utility Model Content

DETAILED DESCRIPTION

[0034] The following describes the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the details in this specification may be modified or altered based on different perspectives and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are intended solely to illustrate the present invention and are not intended to limit the scope of protection of the present invention.

[0035] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention. Therefore, the drawings only show components related to the present invention and are not drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component can be changed at will, and the component layout type may also be more complicated.

[0036] This embodiment proposes a drilling construction structure, such as Figures 1 to 6 As shown, it includes a drilling unit 1 and a connecting unit 2, wherein the connecting unit 2 is connected to the drilling unit 1; Figure 1 、 Figure 2 and Figure 3 As shown, the drilling unit 1 includes a drill tube 3 and a rotary drilling cover 4. The rotary drilling cover 4 is openably connected to the side of the drill tube 3 facing away from the connecting unit 2 (i.e. Figure 3 The bottom of the drill tube 3 forms a hollow cavity; the rotary drilling cover 4 is provided with at least one opening 41 communicating with the cavity; in this embodiment, preferably, there are two openings 41, both of which are provided on the rotary drilling cover 4.

[0037] According to the above technical solution, the drilling unit 1 works through its drill barrel 3 and an openable and closable rotary drilling cover 4. The interior of the drill barrel 3 is designed as a hollow structure to form a cavity for accommodating the drilled soil. The rotary drilling cover 4 is provided with at least one opening 41 (preferably two in this example) connected to the cavity, so that during the rotation of the drill barrel 3, soil can enter the cavity through these openings 41. As the drill barrel 3 continues to drill, the soil in the cavity gradually accumulates until it is filled; when the predetermined drilling depth is reached, the drilling is stopped and the drill barrel 3 is started to be lifted. After the drill barrel 3 is lifted to the ground or a work platform, the rotary drilling cover 4 is opened. The opening of the rotary drilling cover 4 allows the soil in the cavity to be cleaned out, such as dumping or shoveling out, to facilitate the cleaning of the soil. After the soil cleaning is completed, the rotary drilling cover 4 is closed and preparations are made for the next drilling work. This cycle is repeated to achieve efficient and continuous drilling construction.

[0038] As a preferred embodiment, Figure 1 and Figure 4As shown, at least one rotary drilling unit is provided on the rotary drilling cover 4 , and the rotary drilling unit is connected to the rotary drilling cover 4 .

[0039] In one embodiment, the drilling unit includes a cone-breaking head 51, which is fixedly mounted on the drilling cover 4. Specifically, there are one or more cone-breaking heads 51; as an exemplary embodiment, there is one cone-breaking head 51, which is positioned at the center of the drilling cover 4. Of course, it is understood that when there are multiple cone-breaking heads 51, they can be installed in appropriate locations depending on the specific working environment, such as being evenly distributed around the bottom of the drilling cover 4.

[0040] The cone-breaking head 51 of this embodiment is designed to be sharp and strong. When the drill tube 3 and the rotary drilling cover 4 are working together, the cone-breaking head 51 can effectively crush the soil or rock encountered. As the drill tube 3 continues to go deeper, the cone-breaking head 51, with its sharp shape and strong downward pressure, crushes the obstacles encountered and enters the cavity of the drill tube 3 through the opening 41 on the rotary drilling cover 4. When the soil or rock particles in the cavity accumulate to a certain level, the drill tube 3 is lifted and the rotary drilling cover 4 is opened to clean out the crushed material (such as soil). In this process, the cone-breaking head 51 not only improves the efficiency of drilling, but also ensures the smooth progress of drilling. It has a compact structure and strong practicality.

[0041] In another embodiment, Figure 4 As shown, the rotary drilling unit includes a drive housing 52 and a drive motor (not shown) arranged in the drive housing 52. The drive housing 52 is fixed on the rotary drilling cover 4 to protect the drive motor and prevent it from being eroded by the external environment such as soil and moisture. The output shaft of the drive motor passes through the rotary drilling cover 4 and is connected to a drill bit 53. In this embodiment, the drill bit 53 is preferably a compound cone roller drill. It should be noted that the compound cone roller drill is a mechanical component well known to technicians in the relevant technical field, and the specific structure will not be described in detail.

[0042] By arranging a driving motor to drive the drill bit 53 to rotate, it is possible to adapt to complex geological environments and achieve a better effect of breaking hard geological conditions.

[0043] As a preferred embodiment, Figure 1 As shown, the drill barrel 3 includes a barrel body 31, a barrel cover 32 fixedly mounted on the barrel body 31, and a drive unit 33. The drive unit 33 is disposed inside the barrel body 31 and is used to connect to the rotary drilling cover 4. The rotary drilling cover 4 is provided with a connecting plate 401, which is detachably mounted on the barrel cover 32. Specifically, the connecting plate 401 can be mounted on the barrel cover 32 in the form of bolts.

[0044] As a preferred embodiment, the driving unit 33 includes a first connecting rod 331, a folding rod 332 and a hook 333. One end of the first connecting rod 331 is hinged to the connecting plate 401, the other end of the first connecting rod 331 is hinged to the folding rod 332, and the other end of the folding rod 332 (i.e. Figure 1 The bottom end) is connected with the hook 333, further, as Figure 5 As shown, the hook 333 has an L-shaped structure; the hook 333 includes a first hook portion 3331, a second hook portion 3332 and a hook-lifting portion 3333, and the two ends of the second hook portion 3332 are respectively connected to the first hook portion 3331 and the hook-lifting portion 3333, and two mounting plates 335 are connected between the first hook portion 3331 and the second hook portion 3332. The two mounting plates 335 are fixed on the inner wall of the cylinder 31, and the hook 333 is arranged between the two mounting plates 335. The hook 333 is rotatably connected to the two mounting plates 335.

[0045] This embodiment further includes a driving rod 334 , which is connected to the first connecting rod 331 and is used to drive the first connecting rod 331 to change its angle.

[0046] Furthermore, a connecting bar 43 is provided on the rotary drilling cover 4 , and a connecting hole 431 is defined in the connecting bar 43 , and the hook portion 3333 can extend into the connecting hole 431 or detach from the connecting hole 431 .

[0047] The cam 333 is engaged with the first lever 331 and the second lever 332 is engaged with the first lever 331 so as to allow the lever 332 to move in a desired direction and the cam 333 is engaged with the first lever 331. When the hook portion 3333 is completely separated from the connecting hole 431, the rotary drilling cover 4 can be opened, and the soil in the drill tube 3 can be cleaned out. After cleaning, the rotary drilling cover 4 is closed, and the hook portion 3333 is re-extended into the connecting hole 431 to prepare for the next drilling operation.

[0048] As a preferred embodiment, Figure 4As shown, the connecting unit 2 includes a connecting cylinder 21, a cross plate 22 is fixedly provided in the connecting cylinder 21, and a driving member 23 is provided on the cross plate 22. The driving member 23 is connected to the driving rod 334 and is used to drive the driving rod 334 to rise or fall. In this embodiment, the driving member is preferably a cylinder.

[0049] It should be noted that the shape of the folding rod 332 is not limited to the structure and shape shown in the figure of this embodiment; in a possible implementation manner, the folding rod 332 can also be extended out of the cylinder 31. By moving the folding rod 332, the position of the folding rod 332 changes, thereby driving the angle of the hook 333 to change. As the folding rod 332 moves, the hook 333 will gradually disengage from the connecting hole 431, thereby realizing the separation of the rotary drilling cover 4 and the drill barrel 3; compared with the above implementation manner, the structure of this implementation manner is more compact.

[0050] As a preferred embodiment, Figure 6 As shown, it also includes a drilling rig 6, which is rotatably connected to a rotating shaft 7. Specifically, a power motor 8 and a hydraulic telescopic rod 9 are installed on the drilling rig 6. The output shaft of the power motor 8 is connected to the rotating shaft 7. The power motor 8 drives the rotating shaft 7 to rotate. The rotating shaft 7 is coaxially connected to the connecting tube 21. The hydraulic telescopic rod 9 can drive the power motor 8 and the rotating shaft 7 to rise and fall. In this embodiment, the drill rig 6 is the core driving part of the entire drill barrel 3 operation system. The drill rig 6 works in coordination with the power motor 8 and the hydraulic telescopic rod 9 installed thereon. The output shaft of the power motor 8 is closely connected with the rotating shaft 7 on the drill rig 6. When the power motor 8 is started, it drives the rotating shaft 7 to rotate at high speed. This rotation action is transmitted to the connecting tube 21 through a coaxial connection, thereby driving the rotation operation of the entire drill barrel 3, thereby realizing the drilling function of the soil; at the same time, the hydraulic telescopic rod 9 flexibly drives the power motor 8 and the rotating shaft 7 connected thereto to perform lifting and lowering movements, which not only enables the drill barrel 3 to penetrate into the soil, but also can smoothly lift the drill barrel 3 back to the ground after completing the drilling operation, so as to facilitate the unloading of soil and preparation for the next operation.

[0051] The above embodiments are only preferred embodiments for fully illustrating the present invention, and the protection scope of the present invention is not limited thereto. Any equivalent substitution or modification made by those skilled in the art based on the present invention shall fall within the protection scope of the present invention.
