Description

Technical Field

[0001] This application relates to the technical field of detection equipment, and in particular to a device for non-destructive testing of reinforced concrete. Background Art

[0002] The integrated digital rebound hammer, also known as the concrete rebound tester, is a non-destructive measurement tool widely used in the fields of construction, highways, bridges, water conservancy, etc., and is mainly used to evaluate the compressive strength of reinforced concrete and other materials.

[0003] Currently, the existing integrated digital rebound hammer uses a spring to drive a weight. The weight impacts the impact rod that is in perpendicular contact with the concrete surface with a constant kinetic energy, causing local deformation of the concrete and absorbing part of the energy. The other part of the energy is converted into the rebound kinetic energy of the weight. When the rebound kinetic energy is all converted into potential energy, the weight rebounds to the maximum distance, and the instrument displays the maximum rebound distance of the weight in the name of the rebound value (the ratio of the maximum rebound distance to the initial length of the spring). This rebound value can be used to evaluate the compressive strength of the concrete.

[0004] During the test, the impact rod is abutted against the test point by holding the rebound hammer by hand, and then the rebound hammer is pressed in the direction of the test point. However, when the height of the test point is relatively high, it is necessary to climb to a height for testing, which may pose a safety hazard. Summary of the Utility Model

[0005] In order to reduce the safety hazard when the height of the test point is relatively high, this application provides a device for non-destructive testing of reinforced concrete.

[0006] This application provides a device for non-destructive testing of reinforced concrete, adopting the following technical solutions:

[0007] A device for non-destructive testing of reinforced concrete, comprising

[0008] A bearing seat, with support columns arranged at the bottom, and a bearing block is slidably connected to the bearing seat along a direction perpendicular to the support columns;

[0009] A machine body, arranged on the bearing block, and a test rod is slidably connected to the machine body;

[0010] A fixing component, arranged on the bearing block, and the machine body is detachably fixed to the bearing block through the fixing component;

[0011] A driving column, arranged at the bottom of the bearing block, the driving column slides on the bearing seat, and the driving column is parallel to the support column.

[0012] By adopting the above technical solutions, the support column and the bearing seat cooperate with each other, which is beneficial to adapting to different test heights, eliminating the need for climbing heights and reducing the potential safety hazards when the test point height is relatively high. The bearing block can slide flexibly along the direction of the support column, thereby adjusting the detection positions of the machine body and the test rod. This design enables the device to adapt to reinforced concrete structures of different sizes and shapes, improving the flexibility and application range of detection. The test rod slidably connected to the machine body can penetrate deep into the concrete for non-destructive testing, ensuring the accuracy and reliability of the test results. At the same time, the fixing component firmly fixes the machine body on the bearing block, reducing the possibility of shaking or deviation during the testing process and further ensuring the testing accuracy.

[0013] Optionally, the fixing component includes a fixing block and a fixing bolt;

[0014] The fixing block is arranged on the side of the bearing block facing away from the driving column. The fixing block is formed with a through hole, the machine body passes through the through hole, a stop block is arranged on the outer wall of the machine body, and the stop block abuts against the fixing block;

[0015] The fixing bolt is threadedly connected to the bearing block, and the end of the fixing bolt abuts against the side of the machine body facing away from the test rod.

[0016] By adopting the above technical solutions, the fixing component is composed of a fixing block and a fixing bolt, realizing the quick and detachable fixation between the machine body and the bearing block. The through hole on the fixing block allows the machine body to pass through, and the stop block abuts against the fixing block to form a preliminary positioning. Subsequently, by rotating the fixing bolt, its end abuts against the side of the machine body facing away from the test rod to achieve the firm fixation of the machine body.

[0017] Optionally, the support column includes an inner column and an outer column. The outer column is arranged at the bottom of the bearing seat, and the inner column slides up and down in the outer column;

[0018] The outer column is provided with an adjusting member, and the inner column adjusts the distance from the bearing seat through the adjusting member.

[0019] By adopting the above technical solutions, the support column adopts a nested design of an inner column and an outer column, and the distance between the inner column and the outer column is adjusted through the adjusting member. This design enables the device to be flexibly adjusted according to reinforced concrete structures of different heights or thicknesses, ensuring that the test rod can accurately reach the detection position. The adjusting member adopts a cooperation mode of an adjusting bolt and a threaded groove, and the up and down movement of the inner column can be realized by rotating the adjusting bolt. The adjustment process is simple, fast and precisely controllable.

[0020] Optionally, the adjusting member includes an adjusting bolt, and the adjusting bolt slidably penetrates through the outer column along a direction perpendicular to the inner column;

[0021] The side wall of the inner column is evenly spaced with thread grooves along the length direction, and the adjusting bolt is threadedly connected to the thread grooves.

[0022] By adopting the above technical solution, the adjusting bolt slides vertically through the outer column and is threadedly connected to the thread grooves on the side wall of the inner column. This design ensures the stability and reliability of the adjustment process, reducing the possibility of the adjusting bolt loosening or falling off during the adjustment process. At the same time, the thread grooves evenly spaced along the length direction of the side wall of the inner column provide multiple adjustment points for the adjustment, making the adjustment range wider and the adjustment accuracy higher.

[0023] Optionally, the driving column is hinged with an extension column, and a receiving groove for receiving the extension column is formed on the side wall of the driving column.

[0024] By adopting the above technical solution, the length of the driving column is adapted to the length of the support column.

[0025] Optionally, a foot pedal is provided on one side of the support column close to the driving column, and the foot pedal is away from the bearing seat.

[0026] By adopting the above technical solution, the foot pedal provides a stable standing platform for the operator, making it more convenient and safe when adjusting the position of the device or performing other operations.

[0027] Optionally, a reinforcing column is obliquely arranged between the foot pedal and the support column.

[0028] By adopting the above technical solution, the inclined arrangement of the reinforcing column enhances the load-bearing capacity and stability of the foot pedal, preventing accidental collapse or damage during use. At the same time, the reinforcing column can be stepped on during testing to further improve the stability of the bearing seat.

[0029] Optionally, the bearing seat is formed with a sliding groove for the bearing block to slide, a limiting block is arranged on the side wall of the bearing block, and the bearing seat is formed with a limiting groove for the limiting block to slide.

[0030] By adopting the above technical solution, the limiting block slides in the limiting groove, reducing the possibility of the bearing seat in the illustrated sliding groove.

[0031] In summary, the present application includes at least one of the following beneficial effects:

[0032] 1. The support column and the bearing seat cooperate with each other, which is beneficial to adapting to different test heights, eliminating the need to climb high and reducing the safety hazards when the test point height is relatively high;

[0033] 2. The support column adopts a nested design of an inner column and an outer column, and the distance between the inner column and the outer column is adjusted through an adjusting member. This design enables the device to be flexibly adjusted according to reinforced concrete structures of different heights or thicknesses, ensuring that the test rod can accurately reach the detection position.

Detailed Description of the Embodiment

[0039] The following further elaborates on the present application Figures 1-4 with reference to the accompanying drawings.

[0040] An embodiment of the present application discloses a device for non-destructive testing of reinforced concrete.

[0041] Refer to Figure 1 , this embodiment discloses a device for non-destructive testing of reinforced concrete, including a bearing seat 1, and a support column 2 is fixedly connected to the bottom of the bearing seat 1 near the end. A sliding groove 11 is formed on the bearing seat 1, and the extending direction of the sliding groove 11 is perpendicular to the length direction of the support column 2, and the sliding groove 11 penetrates through the bearing seat 1 upward. The bearing seat 1 is provided with a bearing block 3, and the bearing block 3 slides in the sliding groove 11 along the direction perpendicular to the support column 2.

[0042] Refer to Figure 1 and Figure 2 , a limiting block 31 is fixedly connected to the vertical side wall of the bearing block 3, and a limiting groove 12 is formed on the bearing seat 1. The limiting groove 12 is located on the vertical side wall of the sliding groove 11, and the limiting block 31 slides in the limiting groove 12 along the direction perpendicular to the support column 2, for restricting the bearing block 3 from detaching from the sliding groove 11.

[0043] The bearing block 3 is provided with a body 4, and a test rod 41 is slidably connected to the body 4. In order to ensure the stability of the body 4 on the bearing block 3, the bearing block 3 is also provided with a fixing assembly 5 for detachably fixing the body 4.

[0044] See also Figure 1 and Figure 3 The fixing assembly 5 includes a fixing block 51 and a fixing bolt 52. The fixing block 51 is fixedly connected to the top of the bearing block 3 and close to the end. The fixing block 51 is formed with a through hole 511. The hole wall of the through hole 511 adapts to the shape of the part of the body 4 close to the test rod 41. During installation, the test rod 41 of the body 4 first passes through the through hole 511, and then the body 4 passes through the through hole 511. The outer wall of the body 4 is fixedly connected with a stopper 42. When the body 4 passes through the through hole 511, the stopper 42 abuts against the side wall of the fixing block 51.

[0045] A support block facing the fixed block 51 is fixedly connected to the bearing block 3, and a fixing bolt 52 is threadedly connected to the support block. When part of the machine body 4 passes through the through hole 511 until the stopper 42 abuts against the fixed block 51, the fixing bolt 52 is rotated forward until the end of the fixing bolt 52 abuts against the side of the machine body 4 facing away from the test rod 41, and the machine body 4 enters a fixed state.

[0046] In addition, a driving column 6 is fixedly connected to the bottom of the bearing block 3, and a connecting hole connected to the slide groove 11 is formed at the bottom of the bearing seat 1. The driving column 6 slides in the connecting hole and passes through the connecting hole downward, and the driving column 6 is parallel to the support column 2. In the initial state, the bearing block 3 slides to abut against the groove wall of the slide groove 11 on the side away from the support column 2 by toggling the driving column 6, and then the end of the bearing seat 1 abuts against the concrete structure to be tested. At this time, the support column 2 is located between the concrete structure to be tested and the driving column 6; then the driving column 6 is toggled, so that the bearing seat 1 drives the body 4 to move toward the concrete structure to be tested, and then the test rod 41 abuts against the concrete structure to be tested. When the bearing block 3 continues to slide, the test rod 41 slides into the body 4 to complete the test.

[0047] In order to further adapt to the test points of different heights, the support column 2 includes an inner column 21 and an outer column 22. The outer column 22 is fixedly connected to the bottom of the bearing seat 1, and the inner column 21 is slidably connected to the outer column 22. The outer column 22 is also provided with an adjustment member, which includes an adjustment bolt 23. The adjustment bolt 23 is slidably penetrated through the outer column 22, and the sliding direction of the adjustment bolt 23 is perpendicular to the length direction of the inner column 21. A thread groove 211 is formed on the side wall of the inner column 21 opposite to the adjustment bolt 23. There are multiple thread grooves 211 and they are evenly spaced up and down along the length direction. When the inner column 21 stops sliding, align the thread groove 211 with the adjustment bolt 23, and then slide and rotate the adjustment bolt 23 forward, so that the adjustment bolt 23 is threadedly connected to the wall of the thread groove 211, so that the inner column 21 and the outer column 22 enter a fixed state, and the length adjustment of the support column 2 is completed.

[0048] See also Figure 4 In order to make the driving column 6 adapt to the adjusted length of the supporting column 2, the driving column 6 is hinged with extension columns 61 on opposite sides and near the bottom, and the extension columns 61 can be turned up and down. The side wall of the driving column 6 is formed with a receiving groove 62 extending in the vertical direction, and the extension column 61 is received in the receiving groove 62. When the extension column 61 is needed, the extension column 61 can be taken out of the receiving groove 62 and turned downward until the extension column 61 abuts against the groove wall of the receiving groove 62 away from the notch. At this time, the driving column 6 can be operated by turning the extension column 61.

[0049] See also Figure 1 At the same time, in order to further reduce the difficulty of the test, a pedal 24 is fixedly connected to the side wall of the support column 2 close to the driving column 6, and the pedal 24 is arranged away from the bearing seat 1, and a reinforcement column 25 is also tilted and fixed between the pedal 24 and the support column 2. When the driving column 6 abuts against the ground, the pedal 24 abuts against the ground. At this time, the operator can step on the reinforcement column 25 and the pedal 24 to improve the stability of the bearing seat 1. Then, the pedal 24 can be stepped on to provide a stable support point for the support column 2 and the bearing seat 1, which is convenient for moving the driving column 6, reducing the difficulty of operation and safety risks.

[0050] The implementation principle of a device for nondestructive testing of reinforced concrete in the embodiment of the present application is as follows:

[0051] During the test, the operator stands on the pedal 24 and adjusts the overall height and length of the device as needed, so that the test rod 41 is aligned with the point to be tested, and then moves the drive column 6, so that the bearing seat 1 drives the machine body 4 to move toward the point to be tested, until the test rod 41 reaches the point to be tested and slides into the machine body 4, so as to achieve the concrete test. After that, the support column 2 can be slid to move the machine body 4 to the next point to be tested on the same horizontal line for testing. Similarly, after the test on the same horizontal line is completed, the upper and lower heights of the bearing seat 1 are adjusted to test the test points at other heights.

[0052] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
