Technical Field

[0001] The utility model relates to the technical field of pile foundations, and specifically, to a core drilling sampling device for building pile foundation detection. Background Technique

[0002] A pile foundation is a deep foundation composed of piles and a pile cap connecting the pile tops, or a single-pile foundation connecting columns and piles, simply referred to as a pile foundation. If the entire pile body is buried in the soil and the bottom surface of the pile 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 pile cap is above the ground, it is called a high-cap pile foundation. Building pile foundations are usually low-cap pile foundations, and pile foundations are widely used in high-rise buildings.

[0003] The patent specification with the publication number CN216116843U discloses a core drilling sampling device for building pile foundation detection. By removing the bolts fixedly connecting the third mounting frame and the foot pedal, the disassembly of the foot pedal is completed. Then, the user can remove the connecting bolts and push the connecting frame backward. When the connecting frame disengages from the second connecting chute, the user can pull the sampling column downward to complete the disassembly of the sampling column, so that the device has the advantage of being convenient for the user to disassemble and carry, facilitating the user's use.

[0004] However, in the implementation of the related technology, it is found that the above technical solution has the following problems: In the process of using the above device, the disassembly of the foot pedal is completed by removing the bolts fixedly connecting the third mounting frame and the foot pedal. Then, the user can remove the connecting bolts and push the connecting frame backward. When the connecting frame disengages from the second connecting chute, the user can pull the sampling column downward to complete the disassembly of the sampling column. However, the connection relationship between the connecting column and the connecting block of the device is relatively complex, with a high cost, and it is inconvenient to disassemble the connecting column. Therefore, further improvement is needed. Content of the Utility Model

[0005] The utility model provides a core drilling sampling device for building pile foundation detection, which solves the problem in the related technology that it is not convenient to disassemble the core drilling body conveniently.

[0006] The technical solution of the utility model is as follows:

A motor is fixedly connected inside the placement groove. A first semi-circular ring is fixedly connected to one end of the pressure rod. A second semi-circular ring is slidably connected to one end of the pressure rod. A threaded groove is opened at one end of the pressure rod. A threaded rod is arranged on one side of the second semi-circular ring. A rotating block is rotatably connected inside the first semi-circular ring and the second semi-circular ring. A core drilling body is arranged below the pressure rod. The core drilling body is fixedly connected to the rotating block.

[0008] Preferably, a retaining disc is fixedly connected to one end of the pressure rod, and a telescopic rod is fixedly connected to one end of the retaining disc.

[0009] Preferably, the retaining disc is located above the stand, and one end of the telescopic rod is fixedly connected to the upper end of the stand.

[0010] Preferably, a retaining ring is fixedly connected to the inner wall of the placement groove. A rotating shaft is fixedly connected to one end of the motor. A threaded layer is fixedly connected to the outer surface of the rotating shaft.

[0011] Preferably, the rotating shaft penetrates through the inside of the retaining ring.

[0012] Preferably, a first retaining piece is fixedly connected to the inner wall of the first semi-circular ring. A first semi-circular groove is penetrated and opened at one end of the first retaining piece.

[0013] Preferably, a second retaining piece is fixedly connected to the inner wall of the second semi-circular ring. A second semi-circular groove is penetrated and opened at one end of the second retaining piece. A circular hole is penetrated and opened at one end of the second semi-circular ring.

[0017] The working principle and beneficial effects of the present utility model are as follows:

[0018] 1. The utility model controls the telescopic rod to extend and retract to push the baffle plate to drive the pressure rod to move inside the groove. When the lower end of the core drill body is moved to the pile foundation, the telescopic rod stops running, and then the staff controls the motor to start and drive the rotating shaft to rotate. At this time, under the action of the threaded hole and the threaded layer, the rotating shaft drives the rotating block and the core drill body to rotate, and then the telescopic rod is controlled to extend. At this time, the drilling of the pile foundation can be completed with the rotation of the core drill body. As the core drill body goes deeper, the sample will submerge the upper end of the core drill body, so that the sample can be accumulated inside the annular groove.

Detailed implementation mode

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0030] As Figure 1 shown, this embodiment proposes a core drilling and sampling device for building pile foundation detection, including a stand 1. A through groove 11 is penetrated and opened at the upper end of the stand 1, and an assembly and disassembly component 2 is penetrated and arranged inside the through groove 11.

[0031] As Figure 1 shown, the assembly and disassembly component 2 includes a pressing rod 21 penetrating through the inside of the through groove 11. One end of the stop disc 211 is fixedly connected with a telescopic rod 2111, and one end of the telescopic rod 2111 is fixedly connected with the upper end of the stand 1. The telescopic rod 2111 is used to push the pressing rod 21 to move along the inside of the through groove 11.

[0032] As Figure 2 shown, a placing groove 22 is opened at one end of the pressing rod 21. One end of the pressing rod 21 is fixedly connected with a stop disc 211. The stop disc 211 is located above the stand 1. A stop ring 221 is fixedly connected to the inner wall of the placing groove 22. The stop disc 211 is used to prevent the pressing rod 21 from disengaging from the through groove 11, and the stop ring 221 is used to prevent the motor 23 from disengaging from the inside of the placing groove 22.

[0033] As Figure 3 shown, a first semi-circular ring 24 is fixedly connected to one end of the pressing rod 21. A threaded groove 25 is opened at one end of the pressing rod 21. A first stop piece 241 is fixedly connected to the inner wall of the first semi-circular ring 24. A first semi-circular groove 2411 is penetrated and opened at one end of the first stop piece 241. The first stop piece 241 is used to prevent the rotating block 28 from disengaging from the inside of the first semi-circular ring 24 when the rotating shaft 231 and the threaded hole 281 are accidentally disengaged.

[0034] As Figure 4 shown, a motor 23 is fixedly connected inside the placement groove 22. One end of the motor 23 is fixedly connected to a rotating shaft 231. A threaded layer 2311 is fixedly connected to the outer surface of the rotating shaft 231. The rotating shaft 231 passes through the inside of the retaining ring 221. The presence of the threaded layer 2311 facilitates the formation of a fixed connection between the rotating shaft 231 and the threaded hole 281, that is, a fixed connection is formed between the rotating shaft 231 and the rotating block 28.

[0035] As Figure 5 shown, a second semi-circular ring 26 is slidably connected to one end of the pressing rod 21. A second retaining piece 261 is fixedly connected to the inner wall of the second semi-circular ring 26. A second semi-circular groove 2611 is formed by penetrating one end of the second retaining piece 261. A circular hole 262 is formed by penetrating one end of the second semi-circular ring 26. The circular hole 262 communicates with the threaded groove 25. The second retaining piece 261 is used to further prevent the rotating block 28 from detaching from the inside of the second semi-circular ring 26 when the rotating shaft 231 and the threaded hole 281 are accidentally detached.

[0036] As Figure 6 shown, a threaded rod 27 is arranged on one side of the second semi-circular ring 26. The threaded rod 27 is used to form a fixed connection between the second semi-circular ring 26 and one end of the pressing rod 21.

[0037] As Figure 7 shown, a rotating block 28 is rotatably connected inside the first semi-circular ring 24 and the second semi-circular ring 26. A core drill body 29 is arranged below the pressing rod 21. The core drill body 29 is fixedly connected to the rotating block 28. A threaded hole 281 is formed at one end of the rotating block 28. A rotating rod 282 is fixedly connected to the other end of the rotating block 28. The threaded hole 281 is threadedly connected to the threaded layer 2311. The rotating rod 282 passes through the inside of the first semi-circular groove 2411 and the second semi-circular groove 2611. An annular groove 291 is formed at one end of the core drill body 29. The annular groove 291 is used to store samples for pile foundation detection. The core drill body 29 is used to drill into the inside of the pile foundation.

[0038] The working principle and usage instructions of the present utility model are as follows: When sampling the pile foundation is required, first, the staff needs to control the telescopic rod 2111 to extend and retract to push the retaining disc 211 to drive the pressure rod 21 to move inside the through groove 11. When the lower end of the core drill body 29 is moved to the pile foundation part, the telescopic rod 2111 stops operating. Then, the staff controls the motor 23 to start and drive the rotating shaft 231 to rotate. At this time, under the action of the threaded hole 281 and the threaded layer 2311, the rotating shaft 231 drives the rotating block 28 and the core drill body 29 to rotate. Then, control the telescopic rod 2111 to extend. At this time, the drilling of the pile foundation can be completed with the rotation of the core drill body 29. As the core drill body 29 penetrates deeper, its sample will cover the upper end of the core drill body 29, so that the sample can accumulate inside the annular groove 291. Then, taking out the core drill body 29 from the pile foundation can complete the sampling of the sample. When the core drill sampling device needs to be disassembled, the staff rotates the threaded rod 27 so that the threaded rod 27 is separated from the internal parts of the threaded groove 25 and the circular hole 262 in sequence. At this time, the second semi-circular ring 26 and one end of the pressure rod 21 can be removed. Then, when the motor 23 stops and the rotating shaft 231 is fixed, the staff rotates the rotating block 28 so that the threaded hole 281 and the threaded layer 2311 are separated from each other. Then, pull the rotating block 28 vertically to make the threaded hole 281 disengage from the rotating shaft 231. Then, pull the rotating block 28 horizontally, and the rotating block 28 can be taken out from the inside of the first semi-circular ring 24, and the unloading of the core drill body 29 is completed in time, and the inside of the annular groove 291 can be deeply cleaned.

[0039] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
