Description

Technical Field

[0001] The utility model relates to the technical field of pile foundation detection, in particular to a core drilling sampling mechanism for pile foundation detection. Background Technique

[0002] A deep foundation composed of a pile and a pile cap (referred to as a cap) connecting the top of the pile, or a single-pile foundation connecting a column and a pile foundation, is referred to as a pile foundation. If the entire pile body is buried in the soil and the bottom surface of the cap contacts the soil mass, it is called a low-cap pile foundation; if the upper part of the pile is exposed above the ground and the bottom of the cap is above the ground, it is called a high-cap pile foundation. Building pile foundations are usually low-cap pile foundations. In high-rise buildings, pile foundations are widely used. Pile foundation detection refers to the process of evaluating and testing various parameters and performances of underground pile foundations. These detections are usually used to ensure the safety and reliability of pile foundations under design requirements, as well as quality control during the construction process.

[0003] In existing pile foundation detection, the core drilling sampling method is usually adopted. Through core drilling sampling, rock and soil samples deep in the pile foundation can be obtained. These samples can be subjected to detailed analyses in terms of physical properties, engineering properties, and mechanical properties. For example, the density, water content, particle distribution, strength characteristics, etc. of the rock and soil can be determined through laboratory tests. This information is crucial for designing and evaluating the bearing capacity of pile foundations.

[0004] However, in the existing core drilling sampling mechanism, the drill bit is not limited during core sampling, which will cause the drill bit to shake during core sampling, resulting in the deviation of the core sampling position from the target or the accuracy of sampling being affected. This will affect the reliability and accuracy of subsequent rock and soil analyses, and the drill bit shaking may lead to unexpected situations during operation, increasing the safety risk of operators, especially in complex or high-pressure environments. Therefore, a core drilling sampling mechanism for pile foundation detection is proposed to solve the above problems. Content of the Utility Model

[0005] In order to make up for the above deficiencies, the utility model provides a core drilling sampling mechanism for pile foundation detection, aiming to improve the problem of shaking caused by the lack of limitation on the drill bit during core sampling with the drill bit in the prior art.

[0006] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0007] A core drilling and sampling mechanism for pile foundation detection, comprising a main frame. A drilling hole is provided inside the main frame.

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] Refer to Figure 1 and Figure 2 As shown in, an embodiment provided by the present invention: A core sampling mechanism for pile foundation detection includes a main frame 1. A drilling hole 14 is provided inside the main frame 1. A control frame 3 is fixedly connected to the outer wall of the main frame 1. A first fixing column 11 is fixedly connected to the top of the main frame 1. A first motor 9 is fixedly connected to the top of the main frame 1. The output end of the first motor 9 is fixedly connected to a second gear 8. A first gear 7 is fixedly connected to the outer wall of the second gear 8. The outer wall of the first gear 7 is rotatably connected inside the main frame 1. A transmission rod 15 is rotatably connected to the outer wall of the first fixing column 11. A first rack 6 is fixedly connected to one side of the outer wall of the transmission rod 15. The first rack 6 meshes with the first gear 7. A second rack 10 is fixedly connected to one side of the outer wall of the other transmission rod 15. The second rack 10 meshes with the second gear 8. A restraint 12 is rotatably connected to one side of the outer wall of the transmission rod 15. A rolling ball 13 is rotatably connected inside the restraint 12. A moving component is arranged on the outer wall of the main frame 1, and the moving component is used to move the main frame 1.

[0033] Specifically, start motor one 9, drive gear two 8 to rotate through motor one 9, utilize its meshing with rack one 6 to ensure the transmission of large torque and moment, thereby drive drive rod 15 to rotate through rack one 6. Similarly, drive gear one 7 to rotate through motor one 9, utilize its meshing with rack two 10 to ensure the transmission of large torque and moment, thereby drive the corresponding drive rod 15 to rotate through rack two 10. Then drive restrictor 12 to move through drive rod 15, and subsequently drive ball 13 to move through restrictor 12, which can ensure that drill bit 18 maintains a stable position and direction during operation, thereby improving the accuracy and precision of core sampling. This is particularly important for geological exploration and mineral resource assessment that require high-precision sampling. And the stable position of drill bit 18 means that the position deviation and sampling error caused by the shaking of drill bit 18 during the sampling process are reduced, ensuring that the collected samples can truly reflect the situation of the formation.

[0034] Refer to Figure 1 , the moving assembly includes push rod 4 and swivel casters 5. The outer wall of push rod 4 is connected to the outer wall of control frame 3, and the top of swivel casters 5 is fixedly connected to the bottom of main frame 1.

[0035] Specifically, the main frame 1 can be conveniently moved through push rod 4 and swivel casters 5, enabling the operator to move the main frame 1 alone or cooperatively easily without relying on additional transportation equipment or fixed facilities. This saves human resources and improves work efficiency, especially in scenarios where the equipment needs to be frequently adjusted and moved.

[0036] Refer to Figure 1 、 Figure 3 and Figure 4 , a motor two 16 is fixedly connected to the top of main frame 1. The output end of motor two 16 is fixedly connected to a threaded rod 2. The bottom of threaded rod 2 is rotatably connected to the inside of main frame 1. A lifting plate 28 is threadedly connected to the outer wall of threaded rod 2. A drilling rig 17 is fixedly connected to the top of lifting plate 28. The output end of drilling rig 17 is fixedly connected to a rotating disc 19. The outer wall of rotating disc 19 is rotatably connected to the inside of lifting plate 28. A fixed frame 20 is fixedly connected to the outer wall of rotating disc 19. A fixed disc 21 is fixedly connected to one side of the outer wall of fixed frame 20. A drill bit 18 is slidably connected to the inside of fixed disc 21. A fixed block 23 is fixedly connected to the outer wall of rotating disc 19. A fixed column two 27 is fixedly connected to the inside of fixed block 23. A fixing tool 22 is rotatably connected to the outer wall of fixed column two 27. One side of the outer wall of fixing tool 22 is slidably connected to the inside of drill bit 18. A positive and negative thread lead screw 25 is rotatably connected to the inside of fixed block 23. One end of positive and negative thread lead screw 25 is fixedly connected to a knob 24. A fixing plate 26 is threadedly connected to the outer wall of knob 24. The outer wall of fixing plate 26 is rotatably connected to the inside of fixing tool 22.

[0037] Specifically, rotate the knob 24, drive the left - hand and right - hand screw rod 25 to rotate through the knob 24, then drive the fixed plate 26 to move through the left - hand and right - hand screw rod 25, and then drive the fixture 22 to rotate through the fixed plate 26, so that the drill bit 18 can be removed. The process of removing the drill bit 18 can be completed more quickly, saving precious working time, thereby improving work efficiency. Moreover, its operation is more intuitive and simple, reducing the operation complexity and technical requirements of the operator, reducing the possibility of errors. Under harsh environmental conditions, quickly replacing the sampling drill bit 18 can reduce the influence of external factors on the operation and maintain the stability and reliability of the operation.

[0038] Working principle: Place the drill bit 18 inside the fixedly - connected fixed disk 21 which is in sliding connection. Then rotate the knob 24, drive the fixedly - connected left - hand and right - hand screw rod 25 to rotate through the knob 24, then drive the thread - connected fixed plate 26 to move through the left - hand and right - hand screw rod 25. Then drive the rotatably - connected fixture 22 to rotate on the outer wall of the second fixed column 27 to which it is rotatably connected, so as to fix the drill bit 18 inside it. Then push the main frame 1 which is fixedly - connected by the push rod 4 and the swivel caster 5 to a suitable position. Then operate the device through the control frame 3, start the second motor 16, drive the fixedly - connected threaded rod 2 to rotate through the second motor 16, then drive the thread - connected lifting plate 28 to move up and down through the threaded rod 2 until the drill bit 18 reaches the drilling hole 14. Start the first motor 9, drive the fixedly - connected second gear 8 to rotate through the first motor 9, then drive the meshing - connected second rack 10 to rotate through the second gear 8. Then drive the fixedly - connected transmission rod 15 to rotate on the outer wall of the first fixed column 11 to which it is rotatably connected. Similarly, drive the fixedly - connected first gear 7 to rotate through the first motor 9, thereby driving the first rack 6 to rotate, and then drive the fixedly - connected transmission rod 15 to rotate. After that, drive the rotatably - connected restrictor 12 to move through the transmission rod 15. Subsequently, drive the rotatably - connected ball 13 to move through the restrictor 12 to limit the drill bit 18. Finally, start the drill 17 and the second motor 16 to take the core of the pile foundation.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
