[0002] Pile foundations are commonly used basic structural forms in construction projects, and their quality directly affects the safety and stability of the entire building. Therefore, it is very necessary to detect and sample pile foundations. Traditional pile foundation detection and sampling methods are mostly manual operations, which are not only inefficient but also have potential safety hazards. In recent years, with the development of technology, pile foundation detection and sampling equipment has been continuously updated. Among them, the core drilling sampling device has been widely used due to its advantages such as accurate sampling and high efficiency.

[0003] However, when conducting core drilling sampling of pile foundations, due to the different lengths of pile foundations, the required drilling depths are also different, which makes it necessary to install drill pipes during pile foundation core drilling detection. Traditional pile foundation detection core drilling sampling devices often have the situation that it is not convenient to install and quickly disassemble drill pipes, which will affect the efficiency of pile foundation core drilling sampling detection. At the same time, it is very difficult for workers to ensure the flatness of the operating surface at the top of the pile head during the pile head breaking operation before pile foundation core drilling sampling. Therefore, a pile foundation detection core drilling sampling device is needed to maintain a good stable effect on the uneven operating surface. For this reason, the utility model proposes a pile foundation detection core drilling sampling device to solve the above problems.

[0027] Referring to Figures 1 - 3 , a core drilling sampling device for pile foundation detection, comprising a base 1, a top plate 2, a lifting plate 22, a hydraulic cylinder 23, a rotating sleeve 3 and a drill rod for core sampling. A plurality of support columns 21 are fixedly installed between the top plate 2 and the base 1. The lifting plate 22 is slidably installed on the plurality of support columns 21. The number of hydraulic cylinders 23 is two and they are fixedly installed on the top plate 2. The working ends of the two hydraulic cylinders 23 are both fixedly installed on the lifting plate 22. Studs 11 are threadedly installed at the four corners of the base 1. The top and bottom ends of the studs 11 are respectively fixedly installed with adjusting wheels 13 and universal balls. A backing plate 12 is movably installed on the universal balls. Universal wheels 14 are fixedly installed at the four corners of the bottom of the base 1, which facilitates the movement, support and leveling of the device. It can not only be suitable for support on a flat operation surface, but also provide leveling and stable support for the base 1 on an uneven operation surface. An installation opening is provided on the base 1. Two symmetrically arranged electric cylinders 4 are fixedly installed in the installation opening. The mutually approaching ends of the two electric cylinders 4 are both fixedly installed with clamping plates 41. Both clamping plates 41 are arc-shaped, which can fix and limit the drill rod passing through the installation opening, thereby facilitating the disassembly and installation of the drill rod. The rotating sleeve 3 is rotatably installed on the lifting plate 22. The drill rod is axially slidably installed in the rotating sleeve 3. A driving motor 31 is fixedly installed on the lifting plate 22. A first gear 32 and a second gear 33 are respectively fixedly sleeved on the output shaft of the driving motor 31 and the rotating sleeve 3. The first gear 32 and the second gear 33 are meshed with each other, which can drive the rotating sleeve 3 to rotate. Through holes are provided on both the rotating sleeve 3 and the drill rod. Two fixing blocks 34 symmetrically arranged with the rotating sleeve 3 as the center are fixedly installed on the top side of the second gear 33. The same limiting bolt 35 is inserted and installed on the two fixing blocks 34, and the limiting bolt 35 passes through the through holes on the rotating sleeve 3 and the drill rod, which can limit the rotating sleeve 3 and the drill rod, thereby ensuring that the drill rod rotates when the rotating sleeve 3 rotates, and at the same time facilitating the release of the limiting state between the drill rod and the rotating sleeve 3. A hanging frame 5 is rotatably installed on the top plate 2 with damping. An electric hoist 51 is fixedly installed on the hanging frame 5, which is convenient for hoisting the drill rod. A servo motor 52 is fixedly installed on the bottom side of the top plate 2. The output shaft of the servo motor 52 is axially fixedly connected to the hanging frame 5, which can control the turning of the hanging frame 5 as needed.

[0028] In this embodiment, to avoid collision with the top plate 2 during the disassembly and replacement of the drill pipe, the top plate 2 is annularly arranged, and a notch is formed on the top plate 2 for the drill pipe and the hook of the electric hoist 51 to pass through.

[0029] In this embodiment, to facilitate the electric hoist 51 to accurately place the drill pipe to be disassembled and assembled into the rotating sleeve 3 through its hook, a conical hopper 301 is fixedly installed at the top end of the rotating sleeve 3.

[0030] For the circuits, electronic components, and module mechanisms involved, etc., the existing technologies are adopted, and those skilled in the art can fully implement them without further elaboration. The content protected by this application does not involve improvements to software, circuits, and methods either.

[0031] Working principle: When in use, first connect the power supply and adjust the stability and levelness of the base 1 on the uneven operating surface through the cooperation of the adjusting wheel 13 and the cushion plate 12 according to the situation of the operating surface, and provide stable support for the base 1 through the stud 11 in cooperation with the cushion plate 12. Then fix the cushion plate to the operating surface or use a counterweight method to ensure the stability of the base 1 during the core drilling operation. Then drive the lifting plate 22 by the hydraulic cylinder 23 to drive the rotating sleeve 3 to lift and lower, so that the drill pipe can contact the surface of the pile foundation to be drilled. After that, start the driving motor 31, and the driving motor 31 drives the rotating sleeve 3 to rotate through the cooperation of the first gear 32 and the second gear 33. At the same time, under the action of the limit bolt, the drill pipe can be kept rotating synchronously with the rotating sleeve 3, so as to perform the core sampling operation. When the drill pipe needs to be replaced, first lift the drill pipe to be replaced by the hook of the electric hoist 51, then control the servo motor 52 to drive the hanging bracket 5 to rotate, so that the hook of the electric hoist 51 is coaxial with the rotating sleeve 3. Then put the drill pipe into the rotating sleeve 3 and limit the drill pipe through the limit bolt 35. Then the core drilling operation can be carried out again. When the drill pipe needs to be lengthened, first fix the drill pipe to be connected by the clamping plate 41 controlled by the electric cylinder 4 and remove the limit bolt 35. Then hoist the drill pipe to be installed by the hook of the electric hoist 51 to the axis position of the rotating sleeve 3 and lower it to be docked with the drill pipe to be connected. After the docking is completed, limit the upper drill pipe through the limit bolt 35, and then control the clamping plate 41 by the electric cylinder 4 to disengage from the lower drill pipe. Then the core drilling operation can be carried out again.

[0032] It should be noted that the present invention is not limited to the above specific embodiments, and various changes and modifications can be made to the above embodiments according to the teachings of the present invention. These changes and modifications should also be regarded as the protection scope of the present invention.
