Before building materials are put into use, it is usually necessary to sample the building materials and test the samples to determine whether they meet the standards. In construction projects, when testing various indicators of building materials, core drilling sampling is usually used, that is, drilling a hole to take a sample, then taking out the sample core from the drill bit, and finally testing the obtained sample to understand the various indicators of the building materials.

Detailed Implementation

[0015] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application. Example 1:

[0016] This embodiment provides a drilling and sampling device for building materials, including: The frame 1 has a pulley system at its bottom that allows it to move or shift, and a sampling notch 1a is provided on one side of the frame 1; The guide frame includes two guide rods 2 mounted on the frame 1, and a support plate set on the top of the guide rods 2; The guide rod 2 assembly includes a lead screw 3 mounted in the middle of the guide frame and a sliding plate 4 that cooperates with the lead screw 3 and can slide up and down with the guide rod 2; Adjusting handwheel 5 is located on the upper part of the guide frame and connected to lead screw 3. Adjusting handwheel 5 drives lead screw 3 to rotate, thereby realizing the up and down displacement of sliding plate 4 under the limit of guide rod 2; The transmission support component is located on one side of the sliding plate 4 and is directly opposite the sampling notch 1a; The cutting cylinder 6 is detachably fixed to the lower side of the transmission support component; The drive motor 7 is mounted on the sliding plate 4 and is symmetrically arranged with the drive support component; The drive end of the transmission motor 7 transmits torque to the transmission support component through belts and pulleys.

[0017] In this embodiment, the pulley group at the bottom of the frame 1 has a self-locking function, which facilitates the positioning of the equipment. The sampling notch 1a on one side of the frame 1 facilitates drilling and sampling. The guide frame is used to support the guide rod 2 assembly. The lead screw 3 in the guide rod 2 assembly is limited by the support plate and the frame 1, and the sliding plate 4 of the guide rod 2 assembly is limited by the two guide rods 2, allowing the sliding plate 4 to slide up and down along the guide rod 2. The two ends of the lead screw 3 in the guide rod 2 assembly are rotatably mounted between the frame 1 and the support plate through bearing seats and other support components. The middle of the sliding plate 4 in the guide rod 2 assembly has a lead screw 3 nut that cooperates with the lead screw 3, and the two sides of the sliding plate 4 have sliding guide cylinders that slide with the guide rod 2, thereby ensuring that the sliding plate 4 can move up and down along the guide rod 2 during the rotation of the lead screw 3. The adjusting handwheel 5 is fixedly connected to the end of the lead screw 3 by fasteners. The rotation of the adjusting handwheel 5 drives the rotation of the lead screw 3. The cutting cylinder 6 is used for drilling and sampling building materials. The drive motor 7 provides torque to the cutting cylinder 6, and the motor and the cutting cylinder 6 are symmetrically arranged on both sides of the sliding plate 4 to ensure the balance of both sides of the sliding plate 4 and ensure the overall stability of the equipment. The transmission support assembly can better transmit the torque of the drive motor 7 to the cutting cylinder 6, and provide a certain buffering effect to the cutting cylinder 6 when drilling and cutting, thereby preventing damage to the cutting cylinder 6 or the building materials. The cutting cylinder 6 is detachably fixed to the lower side of the transmission support assembly, which facilitates the disassembly and replacement of the cutting cylinder 6, and is suitable for drilling and sampling building materials of different specifications. Example 2:

[0018] This embodiment provides a drilling and sampling device for building materials, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0019] The transmission support components include: The upper support assembly is located on the lower side of the sliding plate 4; The lower support assembly is symmetrical to the upper support assembly and is telescopically connected. Several intermediate support components are disposed between the upper support component and the lower support component, and connect the upper support component and the lower support component; Both the upper support component and the lower support component include: The support plate 8 includes an upper plate body and a lower plate body that are interlocked, and a receiving groove is formed at the connection between the upper plate body and the lower plate body. The transmission connecting rod 9 passes through the middle of the support plate 8, and the support plate 8 has a shaft hole in the middle for it to pass through. The shaft hole is connected to the receiving groove. Several transmission floating components are evenly arranged in a circle on the transmission connecting rod 9 at the center of the support plate 8, and cooperate with the receiving groove. The upper end of the transmission connecting rod 9 in the upper support assembly is connected to the transmission motor 7 via a transmission component such as a pulley, and the transmission connecting rod 9 in the lower support assembly is connected to the cutting cylinder 6; the upper plate of the support plate 8 in the upper support assembly is integrally formed with the sliding plate 4. A retaining spring can be provided at the upper end of the transmission connecting rod 9 in the upper support assembly to prevent the transmission connecting rod 9 from detaching from the sliding plate 4.

[0020] In this embodiment, the upper support assembly is used to connect to the lower side of the sliding plate 4 and receive the torque transmitted from the drive motor 7; the lower support assembly is used to support the cutting cylinder 6 and bear the torque of the upper support assembly, allowing the torque to be transmitted to the cutting cylinder 6. The middle support assembly plays a good supporting, elastic support and buffering role between the upper support assembly and the lower support assembly. The lower cutting cylinder 6 has a certain floating buffering effect at the moment of drilling to prevent damage to the cutting cylinder 6 or building materials.

[0021] The support plates 8 in the upper and lower support assemblies provide support, and the upper and lower plates are connected by fasteners such as bolts and nuts. The transmission connecting rod 9 in the upper support assembly receives the torque from the motor. The transmission connecting rod 9 in the lower support assembly receives the torque transmitted from the transmission connecting rod 9 in the upper support assembly, thus transferring the torque from the upper support assembly to the lower support assembly. The floating transmission component allows the transmission connecting rod 9 in both the upper and lower support assemblies to have a certain floating and vibration reduction effect, thereby improving the stability of drilling. Example 3:

[0022] This embodiment provides a drilling and sampling device for building materials, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0023] The transmission support components also include: The upper transmission rod 10 is integrally formed at the lower end of the transmission connecting rod 9 in the upper support assembly; The lower transmission cylinder 11 is integrally formed at the upper end of the transmission connecting rod 9 in the lower support assembly, and the upper transmission rod 10 is in cooperation with its telescopic transmission. The upper transmission rod 10 includes: Eight transmission teeth 10a are evenly distributed around the circumference, and the ends of the transmission teeth 10a are arc-shaped. Eight transmission slots 10b are evenly distributed circumferentially at the connection between two adjacent transmission teeth 10a, and the bottom of the transmission slots 10b is arc-shaped.

[0024] In this embodiment, the upper transmission rod 10 serves as the transmission end of the transmission connecting rod 9 in the upper support assembly, and the lower transmission cylinder 11 serves as the receiving end in the lower support assembly. The torque is transmitted from the upper transmission rod 10 to the lower transmission cylinder 11, thus achieving good torque transmission and ensuring stable torque transmission. The transmission rod includes 6-8 transmission teeth 10a, which, while ensuring stable transmission, reduce the resistance during the extension and retraction of the upper transmission rod 10 and the lower transmission cylinder 11, or ensure smooth sliding of the upper transmission rod 10 into the lower transmission cylinder 11. The ends of the transmission teeth 10a are arc-shaped, thereby reducing friction. The eight transmission grooves 10b give the transmission rod a petal-like shape, making torque transmission more stable; simultaneously, the bottom of the transmission grooves 10b is arc-shaped, further reducing resistance during extension and retraction. Example 4:

[0025] This embodiment provides a drilling and sampling device for building materials, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0026] The arc diameter at the end of the transmission tooth 10a is larger than the arc diameter at the bottom of the transmission groove 10b, and the arc diameter at the end of the transmission tooth 10a is 1.7-2.0 times the arc diameter at the bottom of the transmission groove 10b, and the angle of the transmission groove 10b is 44-49°; and the inner wall of the upper transmission cylinder is adapted to the lower transmission rod and allows the upper transmission rod 10 to slide up and down.

[0027] In this embodiment, the arc at the end of the transmission tooth 10a is greater than the arc at the end of the transmission groove 10b, so that the angle of the transmission tooth 10a is smaller than the angle of the transmission groove 10b, thereby ensuring the stability and smooth extension and retraction of the upper transmission rod 10 in the lower transmission cylinder 11; while the angle of the transmission groove 10b is 44-49°, which facilitates the processing of the upper transmission rod 10 and its subsequent special fitting, and while ensuring the transmission effect, reduces the obstruction to the extension and retraction process, and ensures the stability of the overall floating extension and retraction of the transmission support component. Example 5:

[0028] This embodiment provides a drilling and sampling device for building materials, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0029] The transmission floating assembly includes: Connecting block 12 is integrally formed on the outer wall of transmission connecting rod 9; The floating component is clamped on one side and fixedly connected to the connecting block 12, while the other end extends into the receiving groove. The receiving groove includes: The extension groove is connected to the shaft hole and is located outside the shaft hole, allowing the connecting block 12 to extend into it and to be clearance-fitted with the connecting block 12. The floating groove is coaxially formed on the outside of the extended groove, has a greater height than the extended groove, and clamps the floating component in a rotational rolling engagement with it.

[0030] In this embodiment, the connecting block 12 serves to support the floating component, providing ample installation space for the floating component; the floating component and the connecting block 12 can be connected by fasteners.

[0031] The extended groove in the receiving groove facilitates the installation of the connecting block 12, and the gap between the connecting block 12 and the connecting block 12 reduces the friction caused by the connecting block 12, thereby ensuring the stability of torque transmission; the floating groove is set and cooperates with the clamping floating component to ensure good limiting support for the clamping floating component, thereby ensuring the stable operation of the transmission floating component. Example 6:

[0032] This embodiment provides a drilling and sampling device for building materials, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0033] The clamping floating component includes: Two floating clamping plates 13 are symmetrically arranged on both sides of the connecting block 12. Each includes a fixing part fixedly connected to one side of the connecting block 12, a receiving part connected to the fixing part and extending perpendicularly away from the connecting block 12, and a clamping part connected to the receiving part and perpendicularly thereto. A positioning hole is formed in the middle of the clamping part. Two floating seats 14 are respectively set inside the clamping part of the floating clamping piece 13 on their respective sides, that is, on the side close to the middle of the connecting block 12. A floating spring 15 is positioned between two floating seats 14 so that the two floating seats 14 elastically abut against each other; Two floating support balls 16 are respectively set on the floating seat 14 on their respective sides, and extend out of the clamping part through the positioning hole of the clamping part on their respective sides, and can roll freely under the limitation of the positioning hole and the floating seat 14. The upper and lower sides of the floating groove are respectively formed with rolling grooves that roll in cooperation with the floating support ball 16 on the corresponding side.

[0034] In this embodiment, the floating clamping plate 13 is made entirely of spring steel, thus possessing a certain degree of elasticity. The fixing part of the floating clamping plate 13 is used to connect with the connecting block 12, the receiving part is used to ensure the spacing between the clamping parts of the two floating clamping plates 13, and the clamping part is used to support the floating seat 14 and the floating support ball 16. By forming a clamping structure through the two floating clamping plates 13, the two floating seats 14 are clamped, ensuring good support for the floating clamping seats. With the setting of the floating spring 15, the two floating seats 14 are elastically limited in front of the two floating clamping plates 13 and will not detach from the floating clamping plates 13. The floating support ball 16 is set to contact the rolling groove of the floating groove, so that the floating transmission component and the receiving groove are in rolling rotational cooperation. At the same time, the floating support plate and the floating spring 15 give the transmission floating component the characteristic of axial up and down elastic floating, thereby further ensuring the overall performance of the transmission support component. Example 7:

[0035] This embodiment provides a drilling and sampling device for building materials, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0036] The central support components include: The upper part of the support base 17 is fixedly connected to the support plate 8 in the upper support assembly, and the lower part is set towards the support plate 8 of the lower support assembly; Several support and retaining components 18 are alternately arranged inside the support base 17 to support the support base 17 and prevent the support base 17 from deforming as a whole; Several lower support connection components connect the lower side of the support base 17 to the support plate 8 in the lower support component; The support base 17 includes: The top support plate 17a is arranged parallel to the support plate 8 in the upper support assembly; Four side support walls 17b extend downward from the four side walls of the top support plate 17a, and buffer grooves are formed between adjacent support side walls. Four supporting base plates 17d are respectively set on the lower side of each side supporting wall 17b, and extend in a direction away from the middle of the supporting top plate 17a, and are set parallel to each other with the supporting plate 8 in the lower supporting assembly. Each support and retaining component 18 connects and supports two side support walls 17b that are arranged opposite to each other.

[0037] In this embodiment, the support base 17 serves as the main frame of the middle support component, ensuring the stability of the overall structure of the middle support component. The support retaining component 18 supports the support base 17, preventing deformation of the support base 17 and ensuring the stability of the support base 17 structure. The lower support component connects the support base 17 and the lower support component, thereby ensuring a good connection between the middle support component and the lower support component.

[0038] The top support plate 17a in the support base 17 forms the main structure connecting to the upper support assembly, while the side support walls 17b, as the receiving structure, together with the bottom support plate 17d, form the structure for installing the lower support connection assembly. Simultaneously, buffer grooves are formed between the four side support walls 17b, allowing them to swing or deform to a certain extent, thereby improving the radial floating and buffering effect of the support base 17 as a whole. Furthermore, the support retaining assemblies 18 connect and support two opposing side support walls 17b, making the side support walls 17b more stable. The support base 17 as a whole can be made of elastic spring steel or copper alloy. Example 8:

[0039] This embodiment provides a drilling and sampling device for building materials, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0040] Support and retention component 18 includes: Two connecting plates 18a are arranged opposite to each other, and each connecting plate 18a abuts against the outer wall of the two oppositely arranged side support walls 17b. Two extension plates 18b are respectively formed on one side of the connecting plate 18a on the side support wall 17b and extend toward the middle of the support base 17, and the side support wall 17b is formed with a groove for the extension plates 18b to extend into. The elastic support plate 18c is located inside the support base 17 and has a multi-segment zigzag structure, connecting the two extension plates 18b. Two fastening bolts 18d fix the connecting plate 18a on the side of the corresponding side support wall 17b to the outside of the side support wall 17b.

[0041] In this embodiment, the connecting plate 18a is used to connect and fix with the side support wall 17b. The connecting plate 18a can be horizontally connected to the side support wall 17b by the fastening bolt 18d. The extension plate 18b can serve as a support, forming the main structure of the support and holding assembly 18 extending into the through groove, avoiding the support and holding assembly 18 from being squeezed and contacted with the side support wall 17b, thus affecting the effect of the support and holding assembly 18. The elastic support plate 18c ensures that the support assembly has good anti-compression and anti-tension effect, and allows the two opposing side support walls 17b to form an elastic support and reinforcement relationship to ensure the stability of the overall structure of the support base 17. Example 9:

[0042] This embodiment provides a drilling and sampling device for building materials, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0043] The central support components also include: The lower fixing base 19 includes two fixing plates that are fastened together and fixed on the support plate 8 of the lower support assembly, and the lower end of the lower support connecting assembly is connected to the lower fixing base 19. The lower support connection component includes: The upper support cylinder 20 is integrally formed on the lower side of the support base plate 17d of the support seat 17; The lower support cylinder 21 is integrally formed on the upper side of the fixing plate located on the upper side of the lower fixing seat 19; The support rod 22 has a rod-shaped end that passes through the upper support cylinder 20 and slides into the support base plate 17d. The upper side of the support base plate 17d is provided with a fastener to limit the rod-shaped end and prevent it from falling off. The other end is a ball head. A spherical groove is formed between the lower support cylinder 21 and the lower fixed seat 19 to limit the ball head and allow the ball head to swing. The support spring 23 is sleeved on the support rod 22, and its two ends abut against the support base plate 17d and the lower fixed seat 19, respectively.

[0044] In this embodiment, the lower fixing seat 19 in the middle support component serves to support the lower support component and the lower support connecting component. The lower fixing seat 19 is fixed to the support plate 8 of the lower support component by fasteners, which facilitates the overall maintenance and installation of the equipment.

[0045] The lower support cylinder 21 and upper support cylinder 20 in the lower support assembly function as a limiter for the support rod 22. The upper support cylinder 20 slides against the support rod 22, allowing the support rod 22 of the support seat 17 to undergo elastic compression or cushioning under the action of the support spring 23. This improves the overall floating cushioning and shock absorption effect of the middle support assembly. Simultaneously, the ball head of the support rod 22 allows the support seat 17 to undergo a certain degree of radial swing, further enhancing the support and connection effect of the middle support assembly.

Step 3, sample testing: Each sample is tested in different ways, including physical property testing (density, thermal properties, electrical properties, etc.), chemical property testing (chemical composition analysis, corrosion resistance testing, etc.), and mechanical property testing (tensile, compression, bending, impact tests, etc.).

[0048] In this embodiment, by determining the diameter of the borehole and the material of the building material, and replacing the corresponding cutting cylinder 6 with one of the appropriate hardness, the convenience of drilling and sampling is facilitated. Furthermore, by performing multi-point equidistant sampling on the same building material, the performance of each sample is ensured to be basically consistent, thereby improving the accuracy of the test. Finally, multi-directional testing ensures the precision of the test.
