Abstract
Description
Technical Field
[0001] This invention relates to the technical field of depth detection, and in particular to a carbonation depth detection device for quality control of large-volume concrete construction. Background Technology
[0002] Carbonation depth testing involves using appropriate tools to create a circular hole on the surface of the test area. The hole should be deeper than the carbonation depth of the concrete, typically greater than 10 mm. Dust and debris are then blown away, and the area should not be washed with water. Phenolphthalein alcohol solution is then sprayed onto the inner surface of the hole. Finally, the depth of the undiscolored concrete is measured multiple times using a carbonation depth meter, and the average value is taken. This average distance is the carbonation depth value of the concrete in the test area.
[0003] However, in existing technologies, holes are typically drilled by directly striking a chisel with a hammer to create a hole in the wall, followed by cleaning with a rubber bulb. However, manually drilling holes with a hammer and chisel results in an uneven interior, with rough edges and irregular internal surfaces. This uneven surface prevents the probe of a carbonation depth measuring instrument from properly contacting the detection surface, affecting measurement accuracy. Consequently, the test results obtained for holes in different locations vary significantly, impacting the overall assessment of concrete carbonation and the accuracy of the test results. Furthermore, the uneven interior of the hole is prone to trapping or obstructing layers, which can hinder external wind force, preventing effective cleaning of the hole's interior. Therefore, even when using tools like rubber bulbs... Cleaning is difficult to ensure complete cleaning of the hole's interior, resulting in incomplete cleaning and residue. Residual debris and dust can cover the carbonized layer, affecting the visual judgment of carbonization depth and causing misjudgments that impact test results. Currently, a hand-held electric drill is used to drill holes. While this method can improve the flatness of the hole to some extent, it is difficult to precisely control the size and depth of the hole manually or with an electric drill. This may result in holes that are too deep or too shallow, affecting work efficiency. Furthermore, holes that are too large can affect the stability of the probe. If the hole is too deep, it may penetrate the target layer, causing the test results to fail to reflect the true structural condition. Conversely, if the hole is too shallow, it may not be able to reach the target layer, thus failing to obtain effective test data.
[0004] To address this, a carbonation depth detection device for the quality control of large-volume concrete construction is proposed, which can quickly, conveniently, and accurately open holes for detection. Summary of the Invention
[0005] The purpose of this invention is to provide a carbonation depth detection device for quality control of large-volume concrete construction, which solves the problem of difficulty in controlling the size of uneven drilled holes.

The half gear meshes with the force-bearing extrusion member, the first spur gear meshes with the transmission blower member, the force-bearing extrusion member is slidably connected to the outside of the support frame, one side of the force-bearing extrusion member and the transmission blower member are rotatably connected to the support frame, one side of the pressure-bearing linkage member is in contact with one side of the force-bearing extrusion member, the driver is used to drive the force-bearing extrusion member and the transmission blower member, when the transmission blower member rotates, it drives the opening shaft to rotate synchronously, when the force-bearing extrusion member rotates, it squeezes the pressure-bearing linkage member, causing the opening shaft to move.
[0007] Furthermore, a circular slot is provided on one side of the detector, one end of the opening shaft passes through the circular slot, an inner groove is provided inside the detector, and an air guide plate is provided inside the inner groove. One end of the air guide plate is fixedly connected to the detector, and the other end of the air guide plate is an inclined plate that gradually tilts towards the circular slot.
[0008] Furthermore, the transmission blower includes a transmission gear rotatably connected to the support frame, and a fan blade fixedly connected to one side of the transmission gear. The transmission gear meshes with the first spur gear, and the fan blade is located near the inner groove.
[0009] Furthermore, one end of the opening shaft is provided with multiple blades at equal angles, and the surface of the blades is provided with multiple saw blades. The height of the saw blades decreases gradually away from the opening shaft, and the surface of the saw blades is parallel to the wall surface.
[0010] Furthermore, the force-bearing pressing component includes a second spur gear rotatably connected to the support frame, and an arc-shaped pressing block fixedly connected to the surface of the second spur gear, the arc-shaped pressing block being in contact with the pressure-bearing linkage component.
[0011] Furthermore, the two ends of the arc-shaped pressure block are divided into a low end point and a high end point. The low end point smoothly transitions to the high end point. The difference between the high end point and the low end point is not less than ten millimeters. The width of the blade is equal to the difference between the high end point and the low end point.
[0012] Furthermore, the output end of the driver is fixedly connected to a transmission shaft, and both the half gear and the first spur gear are fixedly connected to the outside of the transmission shaft. The gear ratio between the half gear and the second spur gear is 1:36.
[0013] Furthermore, the pressure-bearing linkage includes a connecting rod that is slidably connected to the support frame at one end, and an arc block that is fixedly connected to the other end of the connecting rod. The connecting rod has a square through groove, and the width of the arc block is greater than the distance between the lower end point and the higher end point.
[0014] Furthermore, the two sides of the arc block near the arc pressure block are arc-shaped, the arc block is concentric with the second spur gear, and the included angle formed by the two sides of the arc block does not exceed sixty degrees.
[0015] Furthermore, the transmission gear has two straight slots symmetrically opened inside, and two strip blocks are symmetrically fixedly connected to the outside of the perforated shaft. The strip blocks are located inside the straight slots, and a ring is fixedly installed on the outside of the perforated shaft. The ring is located inside the arc groove, and the diameter of the ring is smaller than the diameter of the arc pressure block.
[0016] The beneficial effects of this invention are:
[0017] 1. By driving the force-bearing extrusion component and the transmission blower component to rotate, the transmission blower component drives the opening shaft to rotate synchronously, causing the opening shaft to open holes. The force-bearing extrusion component presses against the opening shaft at intervals, controlling the movement distance of the opening shaft. This allows for precise control of the diameter and depth of the hole, thus avoiding the unevenness and dimensional deviation problems commonly found in manual hole opening. It ensures that the hole size meets the design requirements. Furthermore, the blade at the opening position of the opening shaft maintains the smoothness of the hole wall during the opening process, preventing unevenness or rough edges. This facilitates correct probe contact with the detection surface, improves measurement accuracy, ensures consistency of different hole shapes, enhances the repeatability of accurate detection, and ensures the reliability of the detection results.
[0018] 2. While the opening shaft is driven by the transmission gear, the fan blades rotate simultaneously, generating airflow. The airflow is guided by the air guide plate, and the inclined plate compresses the airflow, thus cleaning the inside of the hole simultaneously during the opening process. This significantly improves the overall efficiency and accuracy of hole opening and carbonization depth detection. The airflow generated by the fan blades can efficiently remove debris and dust from the hole, ensuring the cleanliness of the hole interior, avoiding direct contact between the probe and hard debris, preventing debris from affecting the probe, ensuring the accuracy of the measurement results, and ensuring the consistency and accuracy of the detection depth.
[0019] 3. Hole drilling can be performed simply by holding the detector and starting the driver. This allows for quick and accurate hole drilling, improving construction efficiency by eliminating the need for manual drilling with hammers and chisels. It also significantly improves hole smoothness, avoiding the irregularities and unevenness commonly found in manual drilling. This ensures that the size and depth of each hole meet design requirements, making the probe easy to operate. Even beginners can quickly get started, reducing reliance on manual skills.

[0031] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0032] Reference Figures 1-9 This invention provides a carbonation depth detection device for controlling the quality of large-volume concrete construction. The device includes a detector 1, a probe 2 disposed on one side of the detector 1, an opening shaft 3 rotatably connected inside the detector 1, a driver 4 fixedly disposed inside the detector 1, a half gear 5 and a first spur gear 6 fixedly connected to the output end of the driver 4, a force-bearing compression member 7 rotatably connected to the outside of the first spur gear 6, a pressure-bearing linkage member 8 disposed on one side of the opening shaft 3, a transmission blower 9 slidably connected to the outside of the opening shaft 3, and a support frame 10 fixedly connected inside the detector 1 and rotatably connected to the opening shaft 3. The collar 11 at one end of the shaft 3, and the collar 11 connecting the detector 1 and the support frame 10, the half gear 5 meshes with the force-pressing member 7, the first spur gear 6 meshes with the transmission blower 9, the force-pressing member 7 is slidably connected to the outside of the support frame 10, one side of the force-pressing member 7 and the transmission blower 9 are rotatably connected to the support frame 10, one side of the pressure-receiving linkage 8 is in contact with one side of the force-pressing member 7, the driver 4 is used to drive the force-pressing member 7 and the transmission blower 9, when the transmission blower 9 rotates, it drives the opening shaft 3 to rotate synchronously, when the force-pressing member 7 rotates, it squeezes the pressure-receiving linkage 8, causing the opening shaft 3 to move.
[0033] Reference Figures 1-3 The detector 1 has a circular slot 13 on one side, and one end of the shaft 3 passes through the circular slot 13. The detector 1 has an inner groove 101 inside, and a guide plate 102 is provided inside the inner groove 101. One end of the guide plate 102 is fixedly connected to the detector 1, and the other end of the guide plate 102 is an inclined plate 1021. The inclined plate 1021 gradually tilts along the direction close to the circular slot 13. The detector 1 has a ventilation opening, and a strip groove is provided near the position of the transmission blower 9, so that the air force of the transmission blower 9 can enter the inner groove 101.
[0034] Specifically, when the transmission blower 9 rotates, it drives the perforating shaft 3 to rotate, generating airflow. This airflow enters the inner groove 101 and is guided by the air guide plate 102. As the perforating shaft 3 rotates, it drills holes in the wall. The airflow is guided to the position of the perforating shaft 3, and the airflow is compressed by the inclined plate 1021, causing the airflow to accelerate and blow to the drilling position. Since the detector 1 is in contact with the wall, the airflow only carries the sand and gravel to the outside, thus cleaning the sand and gravel. The cleaned sand and gravel is blocked by the inclined plate 1021, preventing the sand and gravel from entering the interior of the transmission blower 9. Subsequently, it can be further processed using conventional cleaning methods to ensure thorough cleaning.
[0035] Reference Figures 1-7 The transmission blower 9 includes a transmission gear 91 rotatably connected to the support frame 10, and a fan blade 92 fixedly connected to one side of the transmission gear 91. The transmission gear 91 meshes with the first spur gear 6, and the fan blade 92 is located near the inner groove 101.
[0036] Multiple blades 31 are arranged at equal angles at one end of the opening shaft 3. Multiple saw blades are arranged on the surface of the blades 31. The height of the saw blades decreases gradually away from the opening shaft 3, and the surface of the saw blades is parallel to the wall.
[0037] Specifically, when the blade 31 rotates, its outer saw blade drills a hole in the wall. The surface of the saw blade is parallel to the wall, resulting in a relatively flat surface on the surface of the drilled hole that is parallel to the wall. This makes it easier to place the probe 2 and avoids the formation of obstruction areas, allowing the wind generated by the fan blade 92 to effectively clean the hole.
[0038] In addition, the length of a single blade 31 can be 7.5 mm, so the two blades 31 together are 15 mm, ensuring that the diameter of the opening is the conventional 15 mm.
[0039] Reference Figures 2-6 The force-bearing pressing component 7 includes a second spur gear 71 rotatably connected to the support frame 10, and an arc-shaped pressing block 72 fixedly connected to the surface of the second spur gear 71. The arc-shaped pressing block 72 is in contact with the pressure-bearing linkage component 8.
[0040] Reference Figures 2-6The arc-shaped pressure block 72 has two ends: a low point 721 and a high point 722. The low point 721 smoothly transitions to the high point 722. Since the high point 722 is higher than the low point 721, there is a difference between the two. The transition from the low point 721 to the high point 722 is a smooth, gradually increasing arc-shaped transition. This causes the pressure-bearing linkage 8 to gradually move under the pressure of the arc-shaped pressure block 72, ensuring that the arc-shaped block 82 moves the same distance each time it is pressed. The opening shaft 3 corresponds to the movement distance of the arc-shaped block 82. The difference between the high point 722 and the low point 721 is not less than ten millimeters, thus ensuring that the movement distance of the opening shaft 3 is equal to or greater than ten millimeters, ensuring the depth of the opening. At the same time, different pressure-bearing components 7 can be adjusted according to different situations. The width of the blade 31... The difference between the high point 722 and the low point 721 is equal, and one side of the blade 31 is collinear with the outside of the detector 1. That is, when the side of the detector 1 with the circular slot 13 contacts the wall, the blade 31 will also contact the wall. When the drilling shaft 3 moves, the blade 31 will immediately drill a hole in the wall. The distance the blade 31 moves is equal to the difference between the high point 722 and the low point 721. Therefore, the depth of the hole drilled by the blade 31 is also equal to the difference between the high point 722 and the low point 721, thus ensuring the accuracy of each drilling, making the test results more reliable, not affected by external conditions, and having high repeatability. This makes the drilling more stable and repeatable, ensuring consistent hole quality, and facilitating subsequent construction and testing work.
[0041] The difference between the high point 722 and the low point 721 represents the height difference between the two, not the distance between them.
[0042] Reference Figures 1-8 The output end of the driver 4 is fixedly connected to the transmission shaft 41. The half gear 5 and the first spur gear 6 are both fixedly connected to the outside of the transmission shaft 41. When the driver 4 drives the transmission shaft 41 to rotate, the half gear 5 and the first spur gear 6 will rotate simultaneously. At this time, the first spur gear 6 will cause the transmission gear 91 to drive the opening shaft 3 to rotate, while the half gear 5 will intermittently drive the second spur gear 71 to rotate, causing the opening shaft 3 to move intermittently. The gear ratio between the half gear 5 and the second spur gear 71 is 1:36. Since the half gear 5 and the first spur gear 6 will rotate simultaneously, that is, when the second spur gear 71 rotates one revolution, the opening shaft 3 will rotate thirty-six revolutions, so that the opening shaft 3 will rotate and open the hole in a single position for a long time, ensuring the flatness of the opening. At the same time, the fan blade 92 will continuously blow air at this time to clean the position, thereby ensuring that the opening shaft 3 can effectively perform the opening work.
[0043] Specifically, the transmission ratio of the half gear 5 and the second spur gear 71 can be changed to a ratio higher than 1:36, such as 1:72, to further increase the cutting effect of the opening shaft 3 at a single position.
[0044] Reference Figures 1-9 The pressure-bearing linkage 8 includes a connecting rod 81 that is slidably connected to the support frame 10 at one end, and an arc block 82 that is fixedly connected to the other end of the connecting rod 81. The connecting rod 81 has a square through groove 811. The shape of the square through groove 811 prevents the connecting rod 81 from shifting, ensuring that the connecting rod 81 can only move along the path of the support frame 10. The width of the arc block 82 is greater than the distance between the lower end point 721 and the higher end point 722. Therefore, when the arc block 72 moves, the arc block 82 will be immediately squeezed by the arc block 72. The arc block 82 pushes the opening shaft 3 to move, ensuring that the size and depth of the hole meet the standard, avoiding the risk of penetrating the target layer or not reaching the target layer, thereby ensuring the validity and reliability of the test data.
[0045] Reference Figures 1-9 The two sides of the arc block 82 near the arc pressure block 72 are arc-shaped, which allows the arc block 82 to move effectively under the pressure of the arc pressure block 72, reducing friction and avoiding collisions that could cause jamming. The arc block 82 is concentric with the second spur gear 71, and the included angle formed by the two sides of the arc block 82 does not exceed 60 degrees. Since the arc block 82 is centered on the second spur gear 71, the two sides of the arc block 82 will intersect at the center of the second spur gear 71. At this time, the included angle formed by the intersection is 60 degrees, which avoids the high-end point 722 from pressing the arc block 82 for a long time, ensuring that the arc block 82 stays for a relatively similar time at different positions, and ensuring that the blade 31 can cut the wall at different depths for the same time when drilling, thus achieving effective drilling.
[0046] Reference Figures 1-9 The transmission gear 91 has two symmetrical straight slots 911 inside. The shaft 3 has two strip blocks 32 fixedly connected to its exterior. The strip blocks 32 are located inside the straight slots 911. When the transmission gear 91 is driven, the strip blocks 32 will cause the shaft 3 to rotate synchronously. The shaft 3 has a ring 33 fixedly installed on its exterior. The ring 33 is located inside the arc groove 821. The ring 33 can be supported by the arc block 82. Since the arc block 82 will move, the diameter of the ring 33 is smaller than the diameter of the arc pressure block 72, thus preventing the ring 33 from contacting the arc pressure block 72.
[0047] The working principle of this invention is as follows: Hold the detector 1 firmly in your hand, and place the detector 1 with the circular slot 13 against the wall. Start the driver 4, which drives the transmission shaft 41 to rotate. The transmission shaft 41 drives the half gear 5 and the first spur gear 6 to rotate synchronously. The first spur gear 6 directly drives the transmission gear 91 to rotate. When the transmission gear 91 rotates, it drives the fan blade 92 to rotate synchronously. Since the strip block 32 is located inside the straight slot 911, the transmission gear 91 causes the perforated shaft 3 to rotate through the strip block 32. The half gear 5 then intermittently drives the second spur gear 71 to rotate. When the second spur gear 71 rotates, the arc-shaped pressure block 72 rotates synchronously with it. At this time, the arc-shaped block 82 will first contact the lower end 721 of the arc-shaped pressure block 72. As the arc-shaped pressure block 72 rotates, it will gradually press one side of the arc-shaped block 82, causing the connecting rod 81 to slide outside the support frame 10. When the arc-shaped block 82 moves, it will drive the ring 33 to move, which will cause the opening shaft 3 to move as well. When the opening shaft 3 rotates with the transmission gear 91, it will be compressed and translated, stretching the spring 12. The opening shaft 3 causes multiple blades 31 at one end to rotate, drilling into the wall through the blades 31. As the half gear 5 continues to rotate, the arc-shaped pressure block 72 rotates with the second spur gear 71, and the high-end point 722 gradually approaches the arc-shaped block 82. Finally, with the rotation of the second spur gear 71, the high-end point 722 contacts the arc-shaped block 82. At this point, the arc-shaped block 82 moves ten millimeters, and the drilling shaft 3 also drives the blade 31 to move ten millimeters synchronously, thus completing the drilling of ten millimeters. During drilling, because the fan blade 92 rotates synchronously with the transmission gear 91, the fan blade 92 generates wind force. This wind force enters the inner groove 101 and is guided by the air guide plate 102. The wind force is further compressed and guided at the inclined plate 1021. When the probe 1 is in contact with the wall, the wind will blow away the dust and debris generated during drilling, ensuring smooth drilling and reducing subsequent cleaning steps. When the second spur gear 71 rotates 360 degrees, the driver 4 stops, and the arc block 82 reaches the high end 722 of the arc pressure block 72 again. The two will not contact each other at this time. Since the arc block 82 is no longer compressed, the stretched spring 12 will rebound, causing the collar 11 to pull the opening shaft 3 back. The opening shaft 3 will drive the pressure linkage 8 to move back as a whole through the ring 33, so that the arc block 82 will contact the arc pressure block 72 again. At this time, the probe 2 can be used for detection.
[0048] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
