Abstract
Description
Technical Field
[0001] This invention belongs to the field of detection auxiliary device technology, specifically a concrete defect detection auxiliary device. Background Technology
[0002] Concrete defect detection is a crucial step in ensuring the quality and safety of building projects. Concrete defect detection auxiliary devices are used to help identify, detect, or assess internal defects in concrete structures. Through methods such as ultrasound, radar, acoustic emission, or thermal imaging, they help engineers quickly and accurately discover and assess problems in concrete structures.
[0003] The main methods for testing concrete are divided into external defect detection and internal defect detection. Internal defects usually include voids, segregation, non-compactness, internal cracks, etc., which pose a great threat to structural safety. Non-destructive testing is usually carried out using a comprehensive concrete defect tester.
[0004] During testing, two transmitters are arranged opposite each other, with the component under test placed between the two transmitters. However, for certain scenarios, such as when the component under test is suspended at a high altitude, the tester must first draw test points on the upper and lower surfaces of the component under test, then suspend the component under test, and place transducers on the test points on the upper and lower surfaces respectively. The tester below the component under test must hold the transducers by hand and test each test point one by one. The tester has to face the fatigue of holding up his arm for a long time. Holding up his arm for a long time inevitably leads to poor contact between the transducer and the component under test, resulting in abnormal data and rework. Moreover, the tester is in extreme danger below the suspended component. Therefore, this method needs to be improved. Summary of the Invention
[0005] To address the issues raised in the background art, such as the fatigue experienced by inspectors due to prolonged arm-raising during operation, the potential for data anomalies and rework caused by insufficient contact between the transducer and the object being tested, and the extreme danger posed by inspectors being positioned below suspended components, this invention provides an auxiliary device for concrete defect detection.
[0006] To achieve the above objectives, the present invention provides the following technical solution: an auxiliary device for detecting concrete defects, comprising a support assembly and a concrete body, wherein a corner assembly is fixedly installed on the top surface of the support assembly, a connecting assembly is fixedly installed on the top surface of the corner assembly, a base assembly is provided at one end of the connecting assembly, a hammer is fixedly installed at the bottom of the base assembly, a fixing assembly is provided in the inner cavity at the upper end of the base assembly, the support assembly includes a support plate, a support sleeve is fixedly installed at the bottom of the support plate, a support rod is movably connected to the inner cavity of the support sleeve, the support sleeve and the support rod are movably connected by a first bolt, and a nut is movably connected to the outer wall of the first bolt.
[0007] Preferably, the connecting assembly includes a connecting rod, the end of which has a first hole, and the outer wall of the connecting rod is provided with a connecting sleeve. The connecting sleeve is connected to the connecting rod by a second bolt. The side wall of the connecting sleeve has a hole and a nut, and the nut is welded and fixed at the position of the hole.
[0008] Preferably, the base assembly includes a base tube, a slot is provided on one side of the base tube, a second hole and a third hole are provided on the outer wall of the base tube, a dual-head laser body is fixedly installed on one side of the base tube, and a first pin and a second pin are provided on the outer wall of the base tube.
[0009] Preferably, the fixing component includes a fixing cylinder with a notch at the upper end, an opening block fixedly installed in the inner cavity of the fixing cylinder, a spring fixedly installed on the top surface of the opening block, and a transducer body fixedly installed at the end of the spring.
[0010] Preferably, a plurality of test points are evenly arranged on the surface of the concrete body, and the test points are movably connected to the transducer body.
[0011] Preferably, the fixed cylinder is fixedly connected to the base cylinder, and the diameter of the fixed cylinder is smaller than the diameter of the base cylinder, and a connecting line is provided at the lower end of the transducer body.
[0012] Preferably, the first hole at the end of the connecting rod passes through the slot and is connected to the base cylinder by a first pin.
[0013] Preferably, the hammer consists of a connecting rope and a counterweight, and the lower end second pin passes through the second hole and is connected to the connecting rope.

[0015] Preferably, both the support sleeve and the support rod are inclined, and the support assembly is made of stainless steel.
[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0017] This invention utilizes the combination of a transducer body and a concrete body to detect the concrete body. The transducer body is placed on the upper and lower surfaces of the marked detection points on the concrete body. The transducer body is installed at both the upper and lower points, and the positioning is achieved by a dual-head laser body. The test points of the component under test can be arranged on the ground and on the upper surface of the test component. It is not necessary to arrange test points on the lower surface of the component under test to accurately determine the test position. This allows the test personnel to avoid standing directly under the suspended component, thus avoiding the risk of the suspended component falling.
[0018] This invention, through the coordination of connecting components and a plumb bob, utilizes a telescopic connecting rod and a corner component to allow testers to stand in one position to test all measurement points. The plumb bob acts as a counterweight for the device, ensuring that the dual-headed laser body is always vertically upward. The lever principle of the connecting components achieves a labor-saving effect, transforming the initial method of having the tester lift the transducer into applying vertical pressure to the end of the connecting components. This allows the spring to achieve perfect contact between the transducer body and the lower surface of the tested component, resulting in uniform force distribution and protecting the transducer from damage due to excessive force.

Detailed Implementation
[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0031] like Figures 1 to 10 As shown, the present invention provides an auxiliary device for detecting concrete defects, including a support assembly 1 and a concrete body 7. A corner assembly 2 is fixedly installed on the top surface of the support assembly 1, and a connecting assembly 3 is fixedly installed on the top surface of the corner assembly 2. A base assembly 4 is provided at one end of the connecting assembly 3, and a hammer 5 is fixedly installed at the bottom of the base assembly 4. A fixing assembly 6 is provided in the inner cavity at the upper end of the base assembly 4. The support assembly 1 includes a support plate 11, and a support sleeve 12 is fixedly installed at the bottom of the support plate 11. A support rod 15 is movably connected to the inner cavity of the support sleeve 12. The support sleeve 12 and the support rod 15 are movably connected by a first bolt 13. A nut 14 is movably connected to the outer wall of the first bolt 13. The connecting assembly 3 includes a connecting rod 31, and a first hole 32 is opened at the end of the connecting rod 31. The outer wall of component 1 is provided with a connecting sleeve 33, which is connected to the connecting rod 31 by a second bolt 34. The connecting sleeve 33 has a hole and a nut on its side wall, and the nut is welded and fixed in the position of the hole. The base assembly 4 includes a base cylinder 41, a slot 42 is provided on one side of the base cylinder 41, a second hole 43 and a third hole 46 are provided on the outer wall of the base cylinder 41, a dual-head laser body 44 is fixedly installed on one side of the base cylinder 41, a first pin 45 and a second pin 47 are provided on the outer wall of the base cylinder 41, and the fixing assembly 6 includes a fixing cylinder 61, a notch 62 is provided at the upper end of the fixing cylinder 61, an opening block 63 is fixedly installed in the inner cavity of the fixing cylinder 61, a spring 64 is fixedly installed on the top surface of the opening block 63, and a transducer body 65 is fixedly installed at the end of the spring 64.
[0032] Using the above scheme: By cooperating with the connecting component 3 and the base component 4, the support sleeve 12 is welded to the bottom of the support plate 11. The support rod 15 is placed into the support sleeve 12, and the support rod 15 is fixedly installed by the first bolt 13 and the nut 14. The nut 14 is welded to the support sleeve 12. The support sleeve 12 has a round hole at the position where the nut is welded, which facilitates the passage of the first bolt 13, thereby fixing the base and making it more stable during testing. The connecting rod 31 is inserted into the inner cavity of the connecting sleeve 33, and the connecting sleeve 33 and the connecting rod 31 are fixed by the second bolt 34. The end of the first hole 32 enters the inner cavity of the slot 42. The side wall of the connecting sleeve 33 has a round hole, and a nut is welded at the corresponding position of the round hole. Tightening the second bolt 34 can connect the... The connecting rod 31 is connected to the connecting sleeve 33. The connecting rod 31 can be pushed back and forth within the connecting sleeve 33 to achieve leverage and save effort. It can also be used to keep the detection device stationary for testing other measurement points. The axis of the dual-head laser body 44 is parallel to the axis of the base cylinder 41, and the two are fixed together with adhesive. The first pin 45 passes through the second hole 43 to fix the connecting assembly 3 and the hammer 5. The first pin 45 is connected to the connecting rope, thereby fixing the hammer 5 and making it more stable during use. The second pin 47 passes through the third hole 46. The dual-head laser body 44 is designed on the side of the base cylinder 41 away from the support plate 11. Both ends of the dual-head laser body 44 can emit lasers simultaneously. The emitted laser beams are in a straight line. The dual-head laser is mainly used for non-contact, high-precision surface measurement and defect-aided detection. It can quickly and quantitatively acquire information on surface height, flatness, cracks, or depressions, and can be combined with the plumb bob 5 to improve detection accuracy and reliability. Then, the fixed cylinder 61 is inserted into the inner cavity of the base cylinder 41, making the base cylinder 41 and the fixed cylinder 61 fixedly connected. The opening block 63, spring 64, and transducer body 65 are sequentially installed in the inner cavity of the fixed cylinder 61. After installation, the transducer body 65 is placed on the upper and lower surfaces of the marked detection points on the concrete body 7 to detect the concrete body 7. Transducer bodies 65 are set at both the upper and lower points, and are positioned by the dual-head laser body 44. The measured component... The test points can be arranged on the ground and the upper surface of the test component, eliminating the need to place test points on the lower surface of the component to accurately determine the test position. This avoids the risk of the suspended component falling, as the tester does not need to stand directly under it. After the device is set up, it can be extended and retracted via the connecting rod 31. Combined with the corner component 2, this allows the tester to test all test points from a single position. The plumb bob 5 acts as a counterweight for the device, ensuring that the dual-head laser body 44 is always vertically upward. The lever principle of the connecting component 3 achieves a labor-saving effect, transforming the initial method of having the tester lift the transducer into applying vertical pressure to the end of the connecting component 3. This allows the spring 64 to achieve perfect contact between the transducer body 65 and the lower surface of the test component, resulting in uniform force distribution.It also protects the transducer from damage due to excessive force.
[0033] like Figures 6 to 10 As shown, several test points are evenly arranged on the surface of the concrete body 7, and the test points are movably connected to the transducer body 65. The fixed cylinder 61 is fixedly connected to the base cylinder 41, and the diameter of the fixed cylinder 61 is smaller than the diameter of the base cylinder 41. A connecting line is provided at the lower end of the transducer body 65. The support sleeve 12 and the support rod 15 are both set in an inclined shape, and the support component 1 is made of stainless steel.
[0034] The above scheme is adopted: Through the design of the concrete body 7 and the design of several test points on the surface of the concrete body 7, the evenly distributed test points can cover more areas, making the test results more representative of the actual situation of the entire structure. The evenly distributed test points can help engineers quickly locate local quality problems. The evenly distributed test point design allows engineers to more accurately assess the overall strength and durability of the concrete, reducing safety hazards. The test points are movably connected to the transducer body 65, so that the movable transducer body 65 can better test the concrete body 7. The fixed cylinder 61 is fixedly connected to the base cylinder 41, so that the fixed cylinder 61 can be better limited. The diameter of the fixed cylinder 61 is smaller than the diameter of the base cylinder 41, so that the fixed cylinder 61 can be inserted into the inner cavity of the base cylinder 41, thereby fixing the fixing component 6 and avoiding shaking during concrete testing. The design of the bottom connecting line of body 65 allows for better transmission of test data. The inclined design enables the support rod to better utilize the supporting force of the ground and other structures. By changing the support angle, the force borne by the support rod can be evenly distributed, avoiding local overload problems caused by unreasonable support direction. Through reasonable angle design, the strength requirements of the rod can be reduced, thereby reducing the weight and cost of the structure. The material of support component 1 is limited to stainless steel, which is free of harmful substances and has good chemical stability, reducing the risk of harmful substance pollution caused by metal corrosion. The surface is smooth and hard, and it is not easy to get stains during cleaning, making it very convenient to clean. It has high mechanical strength and durability, extending its service life.
[0035] like Figure 2 , Figure 4 and Figure 5As shown, the first hole 32 at the end of the connecting rod 31 passes through the slot 42 and is connected to the base cylinder 41 by the first pin 45. The hammer 5 consists of a connecting rope and a counterweight, and the lower end second pin 47 passes through the second hole 43 and is connected to the connecting rope. The corner assembly 2 includes a first hinge 21. The lower hinge of the first hinge 21 is welded to the support plate 11. The upper hinge of the first hinge 21 is provided with a second hinge 22. The lower section of the second hinge 22 is welded to the upper hinge of the first hinge 21, and the upper section of the second hinge 22 is welded to the connecting sleeve 33.
[0036] The above scheme is adopted: through the cooperation of the first hole 32 and the slot 42, the end of the first hole 32 passes through the slot 42, so that the first hole 32 and the slot 42 are connected to form a rocker arm. The introduction of the rocker arm makes the concrete testing device more automated, and the operator does not need to intervene frequently, reducing the instability factors caused by manual operation and improving the controllability of the entire testing process. The first pin 45 is connected to the connecting rope, thereby fixing the hammer 5, so that the hammer 5 can play a better auxiliary role during testing. The design of the corner component 2 can better support the connecting component 3, making the connecting component 3 more stable during operation. The design of the first hinge 21 and the second hinge 22, with the first hinge 21 being a casement hinge and the second hinge 22 being a flag-shaped hinge, controls the angle and direction of the connecting component 3 to rotate, so that the connecting component 3, the base component 4, the hammer 5 and the fixing component 6 can better test the concrete, avoiding the situation where the tester holds the transducer by hand on the upper and lower surfaces to place the test point.
