Description

Technical Field

[0001] This utility model relates to the technical field of concrete core sampling devices, and in particular to a concrete core sampling device with an anti-splash structure. Background Technology

[0002] Concrete coring equipment is a key device used in fields such as building engineering quality testing, road maintenance, and geological exploration to obtain samples of the internal structure of concrete. It uses a high-speed rotating drill bit to drill holes in concrete components to extract cores in order to analyze performance indicators such as material strength and defect distribution. During the coring operation, the intense friction between the drill bit and the concrete generates a large amount of sand and gravel debris, mud, and dust. These high-speed flying particles not only pose a serious safety threat to the face, eyes, and respiratory tract of operators, but may also pollute the surrounding environment and equipment surface, increasing the difficulty and cost of subsequent cleaning.

[0003] Existing concrete coring devices typically feature protective structures to reduce splashing, commonly designed as fixed protective sleeves or rigid baffles. For example, some devices have a metal sleeve around the drill bit, forming a physical barrier through direct contact between the sleeve and the concrete surface; others use annular baffles bolted to the frame, with the lower edge of the baffle contacting the working surface. However, these fixed protective structures have significant limitations: First, concrete working surfaces often have complex surface features such as unevenness, cracks, or local depressions, making it difficult for rigid protective sleeves or baffles to fit tightly against such surfaces, resulting in large gaps on the sides or bottom, through which splashes can still escape at high speed. Second, during coring, the drill bit needs to continuously penetrate into the concrete, and the contact pressure between the protective structure and the working surface cannot be dynamically adjusted. As the drilling depth increases, the sleeve or baffle may lose contact due to changes in the concrete surface height, further reducing the protective effect. Third, fixed protective structures can only adapt to working surfaces of specific sizes or shapes. When facing curved surfaces, inclined surfaces, or narrow spaces, the protective performance drops significantly, failing to meet the needs of diverse operating scenarios.

[0004] Therefore, to address the above problems, a concrete core sampling device with an anti-splash structure is proposed. Through the combination of a retractable protective structure and a flexible sealing ring, it dynamically adapts to the irregular shape of the concrete surface, eliminates side gaps, and effectively blocks sand and mud splashes. Utility Model Content

[0005] In order to overcome the problems that occur during the daily use of traditional concrete coring equipment, such as the splashing of sand and mud during coring operations causing injury to surrounding workers, and the fact that the fixed protective structure cannot fit tightly against uneven or restricted working surfaces, resulting in excessively large gaps on the sides, allowing mud and debris to splash out at high speed from the gaps.

[0006] The technical solution of this utility model is as follows: a concrete core sampling device with an anti-splash structure, comprising a support, a lifting frame, a connecting frame, a frame, a core sampling assembly, a flow guiding assembly, a lifting assembly, an adjusting assembly, and a rotating assembly. The lifting frame is arranged inside the support, the connecting frame is arranged on one side of the lifting frame, the frame is arranged on one side of the connecting frame, the core sampling assembly is arranged below the frame, the flow guiding assembly is arranged on one side of the core sampling assembly, the lifting assembly is arranged above the support, the adjusting assembly is arranged on one side of the lifting frame, and the rotating assembly is arranged on one side of the connecting frame. The core sampling assembly includes a core sampling motor, a first rotating shaft, and... The machine includes a core drill bit, a first protective sleeve, a guide rod, a second protective sleeve, a return spring, a filter plate, and a sealing ring. A core drill motor is installed above the frame, and a first rotating shaft is installed at the output end of the core drill motor. A core drill bit is installed at one end of the first rotating shaft. A first protective sleeve is installed below the frame, and a guide rod is installed on one side of the first sleeve.

The two ends of the return spring are connected to the bottom surface of the frame and the second protective sleeve, respectively. A filter plate is installed inside the first protective sleeve, and a sealing ring is installed at one end of the second protective sleeve.

[0007] Preferably, the retractable protective structure, consisting of a first protective sleeve, a second protective sleeve, a guide rod, and a return spring, allows the sealing ring to fit snugly against the concrete surface during core sampling. The sealing ring is made of a flexible material that can adapt to irregular surface height variations within a certain range on the concrete surface. During core sampling, as the core drill bit penetrates deeper into the concrete surface, the counterforce of the return spring keeps the second protective sleeve pressed tightly against the sealing ring and the concrete surface, eliminating gaps and preventing the splashing of sand and mud generated during core sampling.

[0008] Preferably, the flow guiding assembly includes a conduit and a connecting box, with the conduit provided on one side of the first protective sleeve and the connecting box provided at one end of the conduit.

[0009] Preferably, the flow guiding assembly also includes a flow guiding pump, which is connected to one side of the connecting box via a pipe.

[0012] Preferably, the adjustment assembly also includes a connecting block, with the connecting block provided on the outer side of the second lead screw, the connecting block and the second lead screw being threadedly connected, and the connecting block and the connecting frame being fixedly connected.

[0013] Preferably, the rotating assembly includes a rotating motor and a second rotating shaft. The rotating motor is provided on one side of the connecting frame, and the second rotating shaft is provided at the output end of the rotating motor. The second rotating shaft and the frame are connected to each other.

[0014] The beneficial effects of this utility model are:

[0015] The retractable protective structure, consisting of a first protective sleeve, a second protective sleeve, a guide rod, and a return spring, ensures that the sealing ring adheres to the concrete surface during core sampling. The sealing ring, made of flexible material, can adapt to irregular surface height variations within a certain range. During core sampling, as the core drill bit penetrates deeper into the concrete surface, the counterforce of the return spring keeps the second protective sleeve pressed tightly against the sealing ring and the concrete surface, eliminating gaps and preventing the splashing of sand and mud generated during core sampling.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figure 1 and Figure 2 This utility model provides an embodiment: a concrete core sampling device with an anti-splash structure, including a support 1, a lifting frame 2, a connecting frame 3, a frame 4, a core sampling assembly, a flow guiding assembly, a lifting assembly, an adjusting assembly, and a rotating assembly. The lifting frame 2 is arranged inside the support 1, the connecting frame 3 is arranged on one side of the lifting frame 2, the frame 4 is arranged on one side of the connecting frame 3, the core sampling assembly is arranged below the frame 4, the flow guiding assembly is arranged on one side of the core sampling assembly, and the lifting assembly is arranged above the support 1. The lifting frame 2... An adjustment assembly is provided on one side of the frame 4, and a rotating assembly is provided on one side of the connecting frame 3. The core-taking assembly includes a core-taking motor 101, a first rotating shaft 102, a core-taking drill bit 103, a first protective sleeve 104, a guide rod 105, a second protective sleeve 106, a return spring 107, a filter plate 108, and a sealing ring 109. The core-taking motor 101 is located above the frame 4. The output end of the core-taking motor 101 is provided with the first rotating shaft 102, and one end of the first rotating shaft 102 is provided with the core-taking drill bit 103. The frame 4 A first protective sleeve 104 is provided below the first sleeve. A guide rod 105 is provided on one side of the first sleeve. A second protective sleeve 106 is slidably connected to the outer side of the guide rod 105. A return spring 107 is provided on the outer side of the guide rod 105. The two ends of the return spring 107 are respectively connected to the bottom surface of the frame 4 and the second protective sleeve 106. A filter plate 108 is provided on the inner side of the first protective sleeve 104. A sealing ring 109 is provided at one end of the second protective sleeve 106. The first protective sleeve 104 and the second protective sleeve 106 are connected to the filter plate 108. 06. The guide rod 105 and the return spring 107 form a telescopic protective structure, which can make the sealing ring 109 fit against the concrete surface when performing core sampling operations. The sealing ring 109 is made of flexible material and can adapt to the irregular surface height changes within a certain range of the concrete surface. During the core sampling operation, as the core drill bit 103 penetrates deeper into the concrete surface, the reaction force of the return spring 107 keeps the second protective sleeve 106 pressing the sealing ring 109 against the concrete surface, eliminating gaps.

[0024] Please see Figure 3 , Figure 4 and Figure 5In this embodiment, the flow guiding component includes a conduit 201 and a connecting box 202. The conduit 201 is provided on one side of the first protective sleeve 104, and the connecting box 202 is provided at one end of the conduit 201. The flow guiding component also includes a flow guiding pump 203. The flow guiding pump 203 is connected to one side of the connecting box 202 through a pipe. In use, the flow guiding pump 203 is started to exhaust the gas, liquid and small particles inside the first protective sleeve 104 and the second protective sleeve 106. The lifting component includes a lifting motor 301 and a first lead screw 302. The lifting motor 301 is provided above the bracket 1, and the first lead screw 302 is provided at the output end of the lifting motor 301. The first lead screw 302 is threadedly connected to the lifting frame 2. In use, the lifting motor 301 is started to drive the first lead screw 302 to rotate, and the rotation of the first lead screw 302 drives the lifting frame 2 to move up and down.

[0025] The adjustment assembly includes a displacement motor 401 and a second lead screw 402. The displacement motor 401 is located on one side of the lifting frame 2, and the second lead screw 402 is located at the output end of the displacement motor 401. The adjustment assembly also includes a connecting block 403, which is located on the outer side of the second lead screw 402. The connecting block 403 and the second lead screw 402 are threadedly connected. The connecting block 403 is fixedly connected to the connecting frame 3. In use, starting the displacement motor 401 drives the second lead screw 402 to rotate, and the rotation of the second lead screw 402 causes the connecting block 403 to move linearly. The connecting block 403 moves linearly, driving the connecting frame 3 to move linearly, thereby adjusting the position of the core drill bit 103 horizontally. The rotating assembly includes a rotary motor 501 and a second rotating shaft 502. The rotary motor 501 is located on one side of the connecting frame 3, and the second rotating shaft 502 is located at the output end of the rotary motor 501. The second rotating shaft 502 is connected to the frame 4. In use, the rotary motor 501 is started to drive the second rotating shaft 502 to rotate, and the rotation of the second rotating shaft 502 drives the frame 4 to rotate, thereby adjusting the angle of the core drill bit 103.

[0026] During operation, the support 1 is first placed near the concrete working surface. The lifting motor 301 is then started, which drives the first lead screw 302 to rotate. The first lead screw 302 lifts the lifting frame 2 to a safe height to prevent the core sampling assembly from colliding with the working surface. Depending on the core sampling position, the displacement motor 401 is started, which drives the second lead screw 402 to rotate. The second lead screw 402 moves the connecting frame 3 and the frame 4 horizontally through the connecting block 403, adjusting the core sampling drill bit 103 above the target area.

[0027] Start the rotary motor 501, which drives the frame 4 to rotate via the second rotating shaft 502. Adjust the angle of the core drill bit 103 to be perpendicular to the working surface. Slowly lower the lifting frame 2 so that the sealing ring 109 at one end of the second protective sleeve 106 contacts the concrete surface. The sealing ring 109 is made of flexible material and adapts to uneven, cracked, or locally dented surface morphology. The reaction force of the return spring 107 pushes the second protective sleeve 106 to slide along the guide rod 105, ensuring that the sealing ring 109 is always tightly pressed against the concrete surface, eliminating side gaps and forming a closed protective space.

[0028] The core sampling motor 101 is started, driving the core sampling drill bit 103 to rotate at high speed via the first rotating shaft 102. At the same time, the lifting frame 2 is slowly pressed down, allowing the drill bit to gradually penetrate deeper into the concrete. The diversion pump 203 is started, extracting sand, gravel, mud, and dust from the first protective sleeve 104 and the second protective sleeve 106 through the conduit 201 and the connecting box 202, preventing particle accumulation in the protective space. The filter plate 108 blocks larger particles from entering the conduit 201, preventing blockage of the diversion system. The sealing ring 109 continuously adheres to the concrete surface, dynamically adapting to changes in the working face height during drilling, ensuring the protective effect throughout the entire core sampling process. After core sampling is completed, the lifting frame 2 is raised, the core sampling motor 101 and the diversion pump 203 are turned off, and the residue on the surface of the filter plate 108 and the sealing ring 109 is cleaned, completing the operation.

[0029] Through the above steps, a retractable protective structure is formed by the first protective sleeve 104, the second protective sleeve 106, the guide rod 105, and the return spring 107. This structure allows the sealing ring 109 to fit against the concrete surface during core sampling. The sealing ring 109 is made of flexible material and can adapt to irregular surface height changes within a certain range on the concrete surface. During the core sampling process, as the core drill bit 103 penetrates deeper into the concrete surface, the reaction force of the return spring 107 keeps the second protective sleeve 106 pressing the sealing ring 109 against the concrete surface, eliminating gaps and preventing the splashing of sand and mud generated during core sampling.

[0030] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
