Description
Technical Field
[0001] This utility model relates to the field of construction machinery technology, and more specifically, to an automatic core sampling and marking device for pile foundations used in circulation. Background Technology
[0002] In pile foundation engineering, core sampling is a crucial quality assessment method. As the main load-bearing structure of a building, the integrity, strength, and uniformity of the pile foundation directly affect the safety and stability of the building. Core sampling, by drilling core samples from the pile, can directly reflect the material properties, internal defects, and construction quality of the pile, and is a key step in assessing whether the pile foundation meets design requirements and identifying potential safety hazards.
[0003] Traditional coring processes rely on manual handwriting of core sample information, which not only suffers from inherent problems such as low marking efficiency, susceptibility to errors and omissions, and difficulty in traceability, but also struggles to meet the timeliness and accuracy requirements of large-scale engineering testing. With the development of digital technology, the need to automatically identify, read, and manage key information from core samples, such as site name, pile type, coring location, coring length, and sample batch, through digital means has become an urgent requirement for improving testing efficiency.
[0004] In view of this, the present invention provides an automatic core sampling and marking device for pile foundations used in circulation, in order to solve the above problems. Utility Model Content

[0007] The inner tube assembly includes a snap ring seat, a snap ring, a short section, and an inner tube. The snap ring seat fixes the snap ring, which is used to fix the core sample. The short section connects to the inner tube, and one end of the inner tube is connected to the drill bit through the inner tube head. While the drill bit rotates on the inner tube head, the inner tube remains stationary during drilling.
[0008] It also includes a core sample identification component, within which a chip implantation unit for storing core samples is provided.
[0009] As a preferred technical solution of this utility model, the other end of the inner tube is connected to an adjusting screw through an inner tube connector, and the adjusting screw is connected to the outer tube connector through a locking nut.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Example 1
[0022] Please see Figure 1 This utility model provides a technical solution: an automatic core sampling and marking device for pile foundations for circulation, comprising an inner tube assembly (1) and an outer tube assembly (2) disposed inside and outside; wherein:
[0023] The outer tube assembly (2) includes a drill bit (21), a reamer (22), and an outer tube (23). The drill bit (21) is located at the front end and is responsible for excavating the rock mass. The reamer (22) follows closely behind to enlarge the borehole diameter and ensure that the inner tube assembly can enter smoothly. The outer tube (23) wraps around the inner tube (15) and plays a protective role. The cap (24) seals the end of the outer tube (23) to ensure the stability of the overall structure. The other end of the outer tube (23) is fixed to the outer tube joint (24) and the upper joint (25) by a wear-resistant stabilizing ring (26).
[0024] It should be noted that the outer casing assembly is used for excavating rock and protecting the inner casing. The drill bit is made of alloy or diamond material to enhance the service life of the drill.
[0025] The inner tube assembly (1) is located inside the outer tube (23) and includes a snap ring seat (11), a snap ring (12), a short section (13), and an inner tube (15). The snap ring seat (11) fixes the snap ring (12), which is used to fix the core sample and prevent it from falling off or being damaged during drilling. The short section (13) connects to other components of the inner tube (15) to ensure the stability of each structure in the inner tube assembly (1). One end of the inner tube (15) is connected to the drill bit (21) through the inner tube head (14). While the drill bit (21) rotates on the inner tube head (14), the inner tube (15) remains stationary during drilling to reduce interference with the core sample.
[0026] It should be noted that the inner tube assembly 1 is a single-action structure to ensure the coordinated movement of the inner tube 15 and the drill bit 21. The other end of the inner tube (15) is connected to the adjusting screw (19) through the inner tube connector (17). The adjusting screw (19) is connected to the outer tube connector (24) through the locking nut (18).
[0027] The adjusting screw (19) and locking nut (18) connect the inner tube head (14) and the drill bit (21) to adjust the gap (2-4mm) between the inner tube head (14) and the drill bit (21) to ensure coordinated movement between the inner tube head (14) and the drill bit (21) and avoid damage to the core sample during drilling.
[0028] This invention marks the core sample information using a ring-shaped core sample marking component 16 at the front end of the inner tube 15. A corresponding remote read / write module 165 reads the data from the RFID chip embedded in the pile foundation core sample. Combined with a drilling depth sensor 162, the drill bit 21 reads the chip data every 25cm of core sample drilled. This effectively solves the problem of information loss caused by core sample breakage and inconsistent lengths during pile foundation core sampling. It also effectively solves the problem of detecting sediment at the bottom of the pile, addressing the issues of manual marking, difficulty in traceability, and low efficiency in existing pile foundation core sampling processes.
[0029] During the core sampling stage of the pile foundation, the outer tube assembly 2, equipped with an alloy or diamond drill bit, ensures effective excavation of the designated pile foundation. The inner tube assembly 1 achieves a static state through a single-action structure design, thereby minimizing interference with the core sample and ensuring its integrity. In addition, the adjusting screw (19) and locking nut (18) can precisely control the gap between the inner tube head (14) and the drill bit (21), ensuring that the core sample is not damaged during the excavation process. The retaining ring seat 11 fixes the retaining ring 12, providing stable support for the drilling process and laying the foundation for subsequent core sample marking and processing.
[0030] Regarding core sample identification, this patent innovatively employs a ring-shaped implantable core sample identification component (16). Using a chip implantation unit 161, an RFID chip containing an radio frequency chip and an embedded depth sensor is embedded inside the pile foundation core sample. This design enables precise measurement and recording of core sample depth information, and optimizes the transmission medium through a double-layer reflective material design, ensuring stable signal transmission. Simultaneously, the tag stores key data such as authorization information and pile number pre-set during the implantation process, providing a reliable basis for subsequent core sample tracking and management.
[0031] A ring-shaped core pattern marking assembly (16) is provided below the inner tube (15) for installing the core pattern marking structure. Specifically, a core pattern marking assembly (16) is provided above the snap ring seat (11), and a chip implantation unit (161) is provided inside the core pattern marking assembly (16). An RFID chip is installed inside the chip implantation unit (161). The chip implantation unit (161) is connected to a depth sensor (162). The depth sensor (162) is located at the front end of the snap ring seat (11), reads drilling depth data in real time, and transmits the data to a signal processor (163) through a data transmission line. The signal processor (163) receives the data from the depth sensor (162) and imports it into the RFID chip. The RFID chip communicates with the remote read / write module (165) through a transmission medium (164) designed with double-layer reflective material to ensure stable signal transmission. The communication module (166) is connected to the remote read / write module (165), which is responsible for assigning a unique identification code to the RFID chip and combining data such as site information and pile foundation number with depth sensor data to complete the dynamic maintenance of core sample information.
[0032] The chip implantation unit (161) adopts a ring structure layout, with a dedicated electronic tag implantation area located at the bottom of the inner tube (15). A high-performance transmission module is integrated to ensure signal stability and data transmission efficiency.
[0033] The depth sensor (162) is located at the front end of the snap ring seat and reads drilling depth data in real time. It is connected to the processor through a data transmission line, and the processor imports the depth data into the radio frequency chip in real time.
[0034] The transmission medium (164) is designed with a double-layer reflective material to optimize signal transmission and reception characteristics and ensure high-efficiency communication quality.
[0035] After the communication module (166) and the remote reading and writing module (165) are integrated, the unique identification code is obtained and assigned to the electronic tag in the electronic tag slot. The communication is completed by combining the preset site information, pile foundation number and other data with the depth sensor data. The remote reading and writing module can also dynamically maintain the core sample information and perform data interaction through the communication interface 167.
[0036] If the core sample is removed from the chip implantation unit (161) and placed in the transfer frame, the core sample is received and confirmed through the transfer frame. An RFID reading device is installed inside the transfer frame to read the RFID tag information on the core sample. The reading device is connected to the information interaction screen, and the operator can query and retrieve the electronic tag information of the core sample through the screen and confirm its entry into the warehouse. This significantly improves the efficiency of pile foundation core sampling and core sample marking, while achieving high-precision positioning and long-term reliability of sample transfer. Through the encircling core sample marking component embedded at the front end of the inner tube, combined with a specially designed control module, read / write module, and depth sensor combination, the RFID chip can be accurately implanted into the pile foundation core sample, giving each sample a unique identifier, thereby achieving simultaneous core sampling and automatic core sample marking. This device can quickly and efficiently complete pile foundation testing, while avoiding the inefficiency and difficulty in traceability of manual marking, providing an efficient, reliable, and convenient solution for related fields.
[0037] Example 2
[0038] This embodiment, based on Embodiment 1, further provides a transfer frame for placing the removed core sample and verifying its label information. The transfer frame features a semi-circular groove design to support core samples of different sizes and lengths. The placement slot is connected to a function key, which is used to manually trigger the reading and verification of the core sample label information to ensure consistency. If the core sample label information is read abnormally, the system will issue an alarm through a warning function to prevent quality problems caused by incorrect or missing information.
[0039] The transfer frame, as the core device for receiving and confirming core samples, has the following main functions:
[0040] RFID Reading and Confirmation: The core tag information is read and verified through the RFID reading device area of the transfer frame, and the sample is initially stored in the warehouse to complete the testing process through the core sample placement operation at the pile foundation core sampling site.
[0041] Information interaction screen: Query and retrieve electronic tag information, and confirm entry into the database.
[0042] Sample placement slot: The semi-circular groove design supports the placement of sample cores of different sizes and lengths, ensuring that each sample core can be placed stably. The function key is used to manually trigger the reading and verification of the sample core label information to ensure consistency.
[0043] The core sampling mechanism is responsible for drilling core samples from the pile foundation and fixing and protecting the core samples through an inner tube assembly. During the core sample drilling process, the core sample identification component 16 records the depth information of the core sample in real time and assigns it a unique identifier through a depth sensor and an RFID chip implantation unit 161. The core sample transfer device receives the drilled core samples, verifies the core sample information through an RFID reader, and displays the information on an interactive screen, completing the core sample storage and transfer. The automation and intelligentization of the pile foundation core sample extraction process can significantly improve detection efficiency and reduce costs. The design of the sensor combination and control module ensures high accuracy in core sample positioning and reliability of the code marking, thereby ensuring that each pile foundation core sample can be uniquely identified and tracked. In addition, this device is compatible with the laboratory's digital transfer function, enabling rapid identification and coding for sample storage and testing without relying on the inefficient method of traditional manual marking. Through this invention, maintenance costs can be further reduced, marking errors can be minimized, and reliable data support can be provided for pile foundation testing, greatly improving the safety and economy of the entire testing process.
[0044] During the core sample transfer stage, the device achieves efficient management of core samples through a transfer frame. The transfer frame features a semi-circular groove design, balancing unobstructed flow and stability, and can support the storage of core samples of different sizes and lengths. Furthermore, the combination of a bar-shaped recognition area and an interactive window enables efficient reading and verification functions, ensuring information accuracy. In case of core sample label reading errors or anomalies, the system will issue an early warning to prevent quality problems caused by information errors or omissions. At the same time, the transfer frame design emphasizes ease of operation, allowing operators to quickly retrieve core samples for subsequent quality inspection and analysis.
