Description

Technical Field

[0001] This utility model relates to the field of building structure monitoring technology, specifically to an adjustable structure for a comprehensive testing instrument for concrete crack defects. Background Technology

[0002] In the field of construction engineering, concrete cracks and other structural defects pose a significant threat to structural safety, durability, and service life. During construction and subsequent use, concrete is highly susceptible to various defects such as cracks, honeycombing, and voids due to the combined effects of material properties, construction techniques, external loads, and environmental conditions. Cracks, in particular, not only weaken the overall strength of the structure but can also trigger a chain reaction, such as steel reinforcement corrosion and accelerated material aging, thus posing a serious challenge to the overall safety of the building.

[0003] In recent years, while concrete crack detection technology has made significant progress, existing methods still have limitations. Visual inspection and crack caliper methods, though simple to operate, are limited to detecting surface cracks and cannot delve into the depth of the cracks or hidden internal defects. While non-destructive testing technologies such as comprehensive concrete crack defect testing instruments and X-rays can reveal internal defects in concrete, their large size, high cost, and complex operation hinder their widespread application in routine maintenance and extensive testing.

[0004] We face numerous challenges due to the shortcomings of current crack detection equipment in terms of ease of operation, and the limitations of traditional detection methods in crack depth analysis and internal defect detection. Most traditional detection instruments can only measure the width of surface cracks, falling short in assessing crack depth and identifying internal defects. Furthermore, when using a comprehensive concrete crack defect tester, operators must hold the transducer close to the crack location for inspection. When the crack is located at a high position, this not only increases the difficulty of operation but also increases the risk of safety accidents, while simultaneously compromising the accuracy and stability of the measurements.

[0005] Therefore, developing a concrete crack detection device that is easy to adjust and suitable for various testing environments has become a technical challenge that urgently needs to be overcome by those skilled in the art. Summary of the Invention

[0006] The purpose of this invention is to provide an adjustable structure for a comprehensive concrete crack defect tester, so as to overcome the problem that the inconvenience of operation in the existing comprehensive concrete crack defect tester leads to limited detection accuracy.

[0007] The present invention solves the above-mentioned technical problems through the following technical solution:

[0008] An adjustable structure for a comprehensive testing instrument for concrete crack defects includes a telescopic support rod, a fixing device, a sliding device, a first planar transducer, a second planar transducer, and the instrument body.

[0009] The sliding device includes a sliding support and a sliding block. The sliding block is divided into a fixed part and a sliding part. The fixed part is fixedly connected to the bottom surface of the fixed device, and the sliding part is fixedly connected to the top of the fixed part. The first planar transducer and the second planar transducer are respectively fixedly installed on the sliding support. The sliding support has a concave structure and is inverted and locked onto the sliding part.

[0010] Several telescopic support rods are connected to the bottom of the fixing device for raising, lowering and supporting the fixing device;

[0011] The telescopic support rod consists of a second support rod and a first support rod from top to bottom. The upper part of the first support rod is provided with a groove, and several limiting protrusions are provided on the groove. A gap is formed between adjacent limiting protrusions. Pulley bearings are provided on both sides of the groove. The second support rod is located between the pulley bearings and can form a vertical moving connection with the first support rod. The second support rod is provided with a through hole. When the telescopic support rod is adjusted to a suitable height, the nut passes through the through hole and is fixedly connected in the corresponding gap.

[0012] The first and second planar transducers are electrically connected to the main body of the test instrument.

[0013] Furthermore, it also includes calipers, which are parallel to the direction of movement of the sliding support and are fixed to the sliding component of the sliding device by screws, for measuring the movement distance of the planar transducer.

[0014] Furthermore, the outer wall of the fixing device is provided with anti-collision foam to prevent damage to the planar transducer.

[0015] Furthermore, the first support rod is provided with an oblique support device, the cross-section of which is a right triangle, wherein the first right-angled side is parallel to the ground and the second right-angled side is perpendicular to the ground, and the first support rod is fixedly connected to the second right-angled side.

[0016] Furthermore, there are four telescopic support rods, which are connected to the bottom of the fixing device; the nuts are wing nuts.

[0017] Furthermore, it also includes a crossbeam, which is perpendicular to the direction of movement of the sliding support and is fixedly connected between two adjacent first support rods.

[0018] Furthermore, the sliding block is a one-piece molded structure.

[0019] Furthermore, the cross-section of the sliding block is I-shaped, with the horizontal part at the bottom being the fixed component and the remaining part being the sliding component.

[0020] Furthermore, the cross-section of the sliding block is convex, with the protruding part of the sliding block being the sliding component and the remaining part being the fixed component.

[0021] Furthermore, it also includes a horizontal telescopic rod, one end of which is fixedly connected to the side wall of the fixing device, and the other end is fixedly connected to the sliding support. It can move horizontally with the sliding support and is used to limit the movement of the sliding support perpendicular to its direction of movement.

[0022] Compared with the prior art, the positive and progressive effects of this utility model are as follows:

[0023] This invention provides an adjustable structure for a comprehensive concrete crack defect testing instrument. Through the design of the telescopic support rod, particularly the sliding connection of the pulley bearing between the second and first support rods, the instrument can freely rise and fall vertically. This allows the instrument to adapt to the needs of detecting concrete cracks at different heights and to concrete components of different sizes and shapes. Simultaneously, the sliding device design allows the first and second planar transducers to move flexibly horizontally, enabling precise positioning of the crack to be detected. This allows for the detection of different types of cracks, expanding the scope of application, improving detection efficiency, and meeting current needs for concrete crack defect detection. The fixed device eliminates the need for manual handling of the planar transducer, improving detection accuracy.

[0024] Furthermore, the addition of calipers allows operators to accurately measure the movement distance of the planar transducer, which helps improve the accuracy and reliability of the test data.

[0025] Furthermore, the outer wall of the fixing device is equipped with anti-collision foam, which can protect the planar transducer from damage caused by accidental collisions and improve the safety performance of the structure.

[0026] Furthermore, an inclined support device is provided on the first support rod, which further enhances the stability of the structure and prevents the testing instrument from tipping over during the testing process.

[0027] Furthermore, the design of four telescopic support rods ensures the stability and adaptability of the testing instrument under different terrains and conditions. Meanwhile, the wing nuts allow for easy tightening and loosening, thereby improving the efficiency of the mounting process.

[0028] Furthermore, the addition of the crossbeam further enhances the overall stability of the structure, enabling the testing instrument to perform efficient and accurate testing in various complex environments.

[0029] Furthermore, the design of the sliding block, whether I-shaped or U-shaped, makes the connection between the sliding support and the sliding component more robust and easier to operate. In particular, the U-shaped sliding block design, combined with the use of a horizontal telescopic rod, effectively restricts the movement of the sliding support in the direction perpendicular to its movement, improving the convenience and stability of operation.

[0045] The present invention will be further described in detail below with reference to the accompanying drawings. The description is intended to explain the present invention and not to limit it.

[0046] See Figure 1 and Figure 2 It includes a telescopic support rod 1, a fixing device 2, a sliding device 3, a first planar transducer 4, a second planar transducer 5, and a test instrument body 6;

[0047] The sliding device 3 includes a sliding support 31 and a sliding block 32. The sliding block 32 is divided into a fixed part and a sliding part. The fixed part is fixedly connected to the bottom surface of the fixed device 2, and the sliding part is fixedly connected to the top of the fixed part. The first planar transducer 4 and the second planar transducer 5 are respectively fixedly installed on the sliding support 31. The sliding support 31 has a concave structure and is inverted and locked onto the sliding part.

[0048] Several telescopic support rods 1 are connected to the bottom surface of the fixing device 2 for lifting and supporting the fixing device 2;

[0049] The telescopic support rod 1 consists of a second support rod 1-2 and a first support rod 1-1 from top to bottom; see also Figure 5 The first support rod 1-1 has a groove on its upper part, and several limiting protrusions 111 are provided on the groove. A gap is formed between adjacent limiting protrusions 111. Pulley bearings 112 are provided on both sides of the groove. The second support rod 1-2 is positioned between the pulley bearings 112, enabling it to move vertically with the first support rod 1-1. (See [reference]) Figure 6 The second support rod 1-2 is provided with a through hole 121. When the telescopic support rod is adjusted to a suitable height, the nut passes through the through hole 121 and is fixedly connected in the corresponding hole.

[0050] The first planar transducer 4 and the second planar transducer 5 are electrically connected to the test instrument body 6; for details, see [link to details]. Figure 1 It is electrically connected to the tester body via connecting cable 7.

[0051] This utility model provides an adjustable structure for a comprehensive concrete crack defect tester. Through the design of the telescopic support rod, particularly the sliding connection of the pulley bearing between the second and first support rods, the tester can freely rise and fall in the vertical direction. This allows the tester to adapt to the needs of concrete crack detection at different heights and to concrete components of different sizes and shapes. Simultaneously, the sliding device design allows the first and second planar transducers to move flexibly in the horizontal direction, thereby accurately locating the crack to be detected, enabling the detection of different types of cracks, expanding the scope of application, improving detection efficiency, and meeting current needs for concrete crack defect detection. The fixed device eliminates the need for manual handling of the planar transducer, improving detection accuracy.

[0052] See Figure 4 In a specific embodiment of the present invention, a caliper 8 is also included. The caliper 8 is parallel to the moving direction of the sliding support 31 and is fixed to the sliding component of the sliding device 3 by screws. It is used to measure the moving distance of the planar transducer. The addition of the caliper design allows the operator to accurately measure the moving distance of the planar transducer, which helps to improve the accuracy and reliability of the test data.

[0053] Preferably, the outer wall of the fixing device 2 is provided with anti-collision foam to prevent damage to the planar transducer. The anti-collision foam on the outer wall of the fixing device protects the planar transducer from accidental impacts, improving the structural safety performance.

[0054] See Figure 1 Preferably, the first support rod 1-1 is provided with an inclined support device 9. The cross-section of the inclined support device 9 is a right-angled triangle, wherein the first right-angled side 91 is parallel to the ground, and the second right-angled side 92 is perpendicular to the ground. The first support rod 1-1 is fixedly connected to the second right-angled side 92. The inclined support device on the first support rod further enhances the stability of the structure and prevents the testing instrument from tipping over during the testing process.

[0055] Specifically, there are four telescopic support rods 1, which are connected to the bottom surface of the fixing device 2; see [link / reference]. Figure 6 The nut is a wing nut (13). The design of four telescopic support rods ensures the stability and adaptability of the tester under different terrains and conditions. At the same time, the wing nut allows for easy tightening and loosening, thus improving the efficiency of the fixing process.

[0056] See Figure 1 Specifically, it also includes a crossbeam 10, which is perpendicular to the moving direction of the sliding support 31 and is fixedly connected between two adjacent first support rods 1-1. The addition of the crossbeam further enhances the overall stability of the structure, enabling the testing instrument to perform efficient and accurate testing in various complex environments.

[0057] Specifically, the sliding block 32 is a one-piece molded structure.

[0058] See Figure 7 Preferably, the cross-section of the sliding block 32 is I-shaped, with the bottom horizontal part being a fixed component and the remaining part being a sliding component.

[0059] Specifically, the cross-section of the sliding block 32 is convex, with the protruding part of the sliding block 32 being a sliding component and the rest being a fixed component.

[0060] The design of the sliding block, whether I-shaped or U-shaped, makes the connection between the sliding support and the sliding component more secure and easier to operate. In particular, the U-shaped sliding block design, combined with the use of a horizontal telescopic rod, effectively restricts the movement of the sliding support in the direction perpendicular to its movement, improving the convenience and stability of operation.

[0061] See Figure 3As a specific embodiment of the present invention, it also includes a horizontal telescopic rod 11. One end of the horizontal telescopic rod 11 is fixedly connected to the side wall of the fixing device 2, and the other end is fixedly connected to the sliding support 31. It can follow the sliding support 31 to move horizontally and is used to limit the movement of the sliding support 31 perpendicular to its moving direction.
