Description

Technical Field

[0001] This utility model relates to the field of strength testing technology, specifically to a device for testing the strength of reinforcing steel bars in water conservancy projects. Background Technology

[0002] A steel reinforcement strength testing device for water conservancy projects is a specialized piece of equipment used to test the strength of steel reinforcement in water conservancy projects. It typically consists of sensors, a data acquisition system, a signal processing unit, and a display terminal. During testing, the sensors acquire physical signals such as stress and strain in the steel reinforcement. The data acquisition system transmits these signals to the signal processing unit, which analyzes and calculates them before displaying key parameters such as the steel reinforcement's strength, yield strength, and tensile strength on the display terminal. This helps engineers assess whether the steel reinforcement performance meets design standards and engineering quality requirements, ensuring the safety and stability of water conservancy project structures. For example, Chinese Patent Publication No. CN222529088U discloses a steel reinforcement strength testing device for water conservancy projects.

[0003] Existing steel reinforcement strength testing devices for water conservancy projects are usually only suitable for testing the overall strength of steel reinforcement, and cannot test the strength of a section of steel reinforcement. In actual water conservancy projects, steel reinforcement may suffer from local corrosion, stress concentration or damage due to factors such as processing technology, transportation loss or construction environment. If these local problems are not detected and dealt with in time, even if the overall strength meets the standards, they will become weak links in the engineering structure. Over time, this can lead to crack expansion, structural deformation or even overall instability, seriously threatening the service life and operational safety of water conservancy projects. Utility Model Content

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a steel reinforcement strength testing device for water conservancy projects, which can effectively solve the problem that the existing technology is only suitable for testing the overall strength of steel reinforcement, but cannot achieve the strength testing of a section of steel reinforcement.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This utility model provides a device for testing the strength of reinforcing steel bars in water conservancy projects, comprising:

[0007] The base has two slide rails symmetrically fixedly connected to both sides of the upper end face along the length direction, and two perforated plates symmetrically fixedly connected to both sides of the upper end face along the width direction. A scale is fixedly connected to both sides of the opposite surfaces of the two perforated plates.

[0008] Furthermore, a vibration assembly and a detection assembly are arranged side by side in the two slides. The vibration assembly includes a first slider slidably connected in the slide. A first index rod is fixedly connected to both sides of the first slider in the width direction, and the first index rod is in contact with a scale. A pair of first electric telescopic rods are fixedly connected to the upper end face of the first slider. A top plate is fixedly connected to the upper end face of the pair of first electric telescopic rods. A vibrator is fixedly connected to the upper end face of the top plate. A clamp is fixedly connected to the bottom of the top plate, and the other end of the clamp is fixedly connected to the output end of the vibrator.

[0009] Furthermore, the first slider is fixedly connected to a resonant recess on its upper end face between a pair of first electric telescopic rods. Multiple elastic conductive blocks are fixedly connected to the outer arc surface of the resonant recess in a linear array. Multiple diffusers corresponding to the elastic conductive blocks are fixedly connected to the inner arc surface of the resonant recess in a linear array. A resonant block is fixedly connected to the inner bottom of the resonant recess. Multiple resonant ropes are fixedly connected to both sides of the upper end face of the resonant block, and the other end of the resonant rope is fixedly connected to the inner top of the resonant recess.

[0010] Furthermore, the detection component includes a second slider slidably connected in a slide rail. A second index rod is fixedly connected to both sides of the second slider in the broadband direction, and the second index rod is in contact with a scale. A pair of second electric telescopic rods are fixedly connected to the upper end face of the second slider. A fixing plate is fixedly connected to the upper end face of the pair of second electric telescopic rods. A frequency detector is fixedly connected to the upper end face of the fixing plate, and a vibration damping head is fixedly connected to the bottom of the fixing plate.

[0011] Furthermore, the second slider is fixedly connected to a vibration-absorbing recess on its upper end face between a pair of second electric telescopic rods. The outer arc surface of the vibration-absorbing recess is connected to a rectangular array of multiple guide contacts. The other end of each guide contact extends through the vibration-absorbing recess into the interior of the vibration-absorbing recess and is fixedly connected to an arc-shaped vibration-distributing plate. Vibration-absorbing blocks are fixedly connected to both inner walls of the vibration-absorbing recess, and the other side of the vibration-absorbing block extends through the inner wall of the vibration-absorbing recess. A vibration-inducing rod is fixedly connected to the other side of the vibration-absorbing recess, and the other end of the vibration-inducing rod is fixedly connected to the detection end of the frequency detector.

[0012] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0013] 1. By extending and retracting the first electric telescopic rod in the vibration assembly, the top plate and the first slider move closer and further apart, thereby achieving the clamping and fixing of the clamp head to one end of the rebar placed in the resonant recess. The clamp head also transmits the vibration force generated by the vibrator to the rebar. When the vibration force is transmitted to the rebar, since part of the rebar is in contact with the resonant recess through the elastic transmission block, the vibration force is transmitted to the interior of the resonant recess. The vibration force is amplified by the resonant block and the resonant rope. The contact between the rebar and the resonant recess through the elastic transmission block allows the vibration force to be transmitted to the resonant recess. With the synergistic effect of the resonant block and the resonant rope, the vibration force is effectively amplified, thereby improving the strength and clarity of the detection signal, and thus improving the sensitivity and accuracy of rebar strength detection. The slider can more accurately locate local quality problems of the rebar, effectively solving the problem that traditional detection devices are difficult to detect local strength of rebar.

[0014] 2. By detecting the extension and retraction of the second electric telescopic rod in the detection component, the fixed plate and the second electric telescopic rod are brought closer and further apart, thereby achieving the compression and fixation of the vibration damping head and the other end of the steel bar placed in the vibration-absorbing recess. A part of the vibration-absorbing recess contacts the steel bar through guide contacts, thereby receiving the vibration force transmitted from one end of the resonant recess by the steel bar. This force is then collected and guided into the vibration-absorbing recess by the arc-shaped vibration distribution plate. The vibration force guided into the vibration-absorbing recess is further captured by the vibration-absorbing block and transmitted to the frequency detector through the vibration-inducing rod. This enables the frequency detector to detect the vibration force in the vibration-absorbing recess. The capture of the vibration force by the vibration-absorbing block and the transmission of the signal by the vibration-inducing rod allow the frequency detector to accurately acquire the vibration force signal. By analyzing the vibration frequency of the steel bar and combining it with the resonance enhancement design of the vibration component, a more detailed analysis of the internal structural characteristics of the steel bar can be achieved, enabling accurate detection of the steel bar strength.

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] The present invention will be further described below with reference to the embodiments.

[0027] Example: Refer to Figures 1 to 2 A device for testing the strength of reinforcing steel bars in water conservancy projects, comprising:

[0028] The base 1 has two slide rails 11 symmetrically fixedly connected to both sides of the upper end face along the length direction, and two perforated plates 13 symmetrically fixedly connected to both sides of the upper end face along the width direction. A scale 12 is fixedly connected to both sides of the opposite face of the two perforated plates 13.

[0029] The steel bars are fixed through the entire structure using the perforated plate 13, while the scale 12 is used to determine the section where the strength of the steel bars needs to be tested.

[0030] Reference Figure 1 , Figure 3Two slide rails 11 are arranged side by side with a vibration component 2 and a detection component 3. The vibration component 2 includes a first slider 21 slidably connected in the slide rail 11. A first index rod 22 is fixedly connected to both sides of the first slider 21 in the width direction, and the first index rod 22 is in contact with the scale 12. A pair of first electric telescopic rods 23 are fixedly connected to the upper end face of the first slider 21. A top plate 24 is fixedly connected to the upper end face of the pair of first electric telescopic rods 23. A vibrator 26 is fixedly connected to the upper end face of the top plate 24. A clamp 261 is fixedly connected to the bottom of the top plate 24, and the other end of the clamp 261 is fixedly connected to the output end of the vibrator 26.

[0031] The distance between the vibration component 2 and the detection component 3 is adjusted using the slide rail 11. The distance between the vibration component 2 and the detection component 3 represents the section of steel bar that needs to be detected. The first index rod 22, together with the scale 12, determines the position of the first slider 21 in the base 1. At the same time, when the steel bar is placed in the resonant recess 25 through the hole plate 13, the first electric telescopic rod 23 begins to retract, thereby causing the clamp 261 to gradually approach the steel bar, thereby achieving the clamp 261 to squeeze and fix the steel bar located at one end of the resonant recess 25. After the clamp 261 completes the squeezing and fixing of the steel bar, the vibrator 26 starts to work and transmits the vibration force to the corresponding steel bar position through the clamp 261.

[0032] Reference Figures 3 to 4 The first slider 21 is located between a pair of first electric telescopic rods 23. A resonant recess 25 is fixedly connected to the upper end face of the first slider 21. Multiple elastic conductive blocks 27 are fixedly connected to the outer arc surface of the resonant recess 25 in a linear array. Multiple diffusers 28 corresponding to the elastic conductive blocks 27 are fixedly connected to the inner arc surface of the resonant recess 25 in a linear array. A resonant block 29 is fixedly connected to the inner bottom of the resonant recess 25. Multiple resonant ropes 210 are fixedly connected to both sides of the upper end face of the resonant block 29, and the other end of the resonant rope 210 is fixedly connected to the inner top of the resonant recess 25.

[0033] The elastic transmission block 27 in the resonant recess 25 contacts the reinforcing bar. Because the elastic transmission block 27 is elastic, it can be used with the clamp 261 to compress and fix reinforcing bars of different specifications. When the vibration force is transmitted to the reinforcing bar, since part of the reinforcing bar contacts the resonant recess 25 through the elastic transmission block 27, the vibration force is transmitted to the interior of the resonant recess 25 through the release and diffusion of the diffuser 28. The vibration force is enhanced by the resonant block 29 and the resonant rope 210. The reinforcing bar contacts the resonant recess 25 through the elastic transmission block 27, so that the vibration force is transmitted to the resonant recess 25. With the synergistic effect of the resonant block 29 and the resonant rope 210, the vibration force is effectively amplified.

[0034] Reference Figure 1 , Figure 5The detection component 3 includes a second slider 31 slidably connected in the slide rail 11. The second slider 31 has a second index rod 32 fixedly connected to both sides in the broadband direction, and the second index rod 32 is in contact with the scale 12. A pair of second electric telescopic rods 33 are fixedly connected to the upper end face of the second slider 31. A fixing plate 34 is fixedly connected to the upper end face of the pair of second electric telescopic rods 33. A frequency detector 35 is fixedly connected to the upper end face of the fixing plate 34. A vibration damping head 351 is fixedly connected to the bottom of the fixing plate 34.

[0035] The position of the second slider 31 in the base 1 is determined by the second index rod 32. By determining the position of the second slider 31 and the first slider 21 in the base 1, the distance between the vibration component 2 and the detection component 3 is determined (this distance represents the section of the steel bar that needs to be detected). The second electric telescopic rod 33 retracts to make the vibration damping head 351 contact the steel bar. The vibration damping head 351, together with the vibration absorption recess 36, completes the compression and fixation of the other end of the steel bar. At the same time, the vibration damping head 351 can prevent the vibration force from being transmitted to the fixing plate 34, thereby affecting the detection result of the frequency detector 35.

[0036] Reference Figures 5 to 6 The second slider 31 is fixedly connected to the upper end face of the pair of second electric telescopic rods 33 with a vibration-absorbing recess 36. The outer arc surface of the vibration-absorbing recess 36 is connected to a rectangular array of multiple guide contacts 37. The other end of each guide contact 37 extends through the vibration-absorbing recess 36 into the interior of the vibration-absorbing recess 36 and is fixedly connected to an arc-shaped vibration-distributing plate 38. Both sides of the inner wall of the vibration-absorbing recess 36 are fixedly connected to vibration-absorbing blocks 39, and the other side of the vibration-absorbing blocks 39 extends through the inner wall of the vibration-absorbing recess 36. The other side of the vibration-absorbing recess 36 is fixedly connected to a vibration-inducing rod 310, and the other end of the vibration-inducing rod 310 is fixedly connected to the detection end of the frequency detector 35.

[0037] By utilizing multiple guide contacts 37 in the vibration-absorbing recess 36 to make multi-point contact with the outer circumference of the reinforcing bar, the vibration of the reinforcing bar is transmitted through multiple guide contacts 37. After being concentrated by the arc-shaped vibration-dispersing plate 38, it is dispersed into the vibration-absorbing recess 36. The vibration force dispersed into the vibration-absorbing recess 36 is further captured by the vibration-absorbing block 39 and guided to the detection end of the frequency detector 35 by the vibration-guiding rod 310, thereby realizing the detection of the vibration force in the current vibration-absorbing recess 36 by the frequency detector 35.

[0038] The working principle of this utility model is as follows:

[0039] First, the operator inserts the reinforcing bar to be tested through the hole plate 13, so that the local section to be tested is located between the vibration component 2 and the testing component 3. The distance between the two is adjusted by sliding the first slider 21 and the second slider 31. The length of the test section is located by using the cooperation of the first index rod 22, the second index rod 32 and the scale 12 (for example, if the middle 50cm section of the reinforcing bar needs to be tested, the distance between the two sliders is adjusted to 50cm).

[0040] Then the operator starts the first electric telescopic rod 23, which retracts to drive the top plate 24 down. The clamp 261 gradually presses one end of the steel bar (located in the resonant recess 25). The operator observes the degree of compression of the elastic transmission block 27 to ensure that the steel bar is in close contact with the resonant recess 25 without shaking. When the vibrator 26 is turned on, the vibration force is transmitted to the steel bar through the clamp 261 and simultaneously transmitted to the inside of the resonant recess 25 through the elastic transmission block 27. The resonant block 29 and the resonant rope 210 work together to amplify the vibration force and evenly diffuse it to the steel bar in the detection section through the diffuser hood 28, so that the steel bar produces stable vibration.

[0041] The operator simultaneously activates the second electric telescopic rod 33, causing the fixed plate 34 to descend and the vibration damping head 351 to press the other end of the reinforcing bar (located in the vibration absorption recess 36), thus isolating the vibration interference of the non-detection section.

[0042] The vibration of the steel bar is transmitted to the vibration-absorbing recess 36 through the guide contact 37. After being collected by the arc-shaped vibration distribution plate 38, the vibration signal is captured by the vibration-absorbing block 39 and transmitted to the frequency detector 35 through the vibration-inducing rod 310. The operator observes the vibration frequency data displayed by the frequency detector 35 in real time to determine the strength characteristics of the steel bar detection section.

[0043] The operator analyzes the strength distribution of the tested section based on the vibration frequency fed back by the frequency detector 35 and the standard parameters of the steel reinforcement material.

[0044] If the vibration frequency is stable and meets the standard value, the strength of the steel bar in that section is considered normal.

[0045] If the frequency is abnormal (such as large fluctuations or deviations from the standard value), it indicates that the detection section may have rust, damage or stress concentration, and further verification is required.

[0046] After the inspection is completed, the operator extends the first electric telescopic rod 23 and the second electric telescopic rod 33, loosens the reinforcing bar, slides the slider to change the inspection section, and repeats the above steps to complete the inspection of the entire section.

[0047] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
