Description
Technical Field
[0001] The utility model relates to the technical field of concrete defect detection, in particular to a device for detecting internal defects of highway concrete structures. Background Technique
[0002] Concrete structures are common structural types in buildings, including building walls, bridges, roads, and water conservancy projects. However, concrete structures also face various problems during use, some of which are caused by internal defects in the concrete. Internal defects in concrete can cause many problems, such as reducing structural strength, accelerating structural aging, and leading to structural collapse. Therefore, the detection of internal defects in concrete is very important.
[0003] Non-metallic ultrasonic detectors are commonly used concrete defect detection equipment. Utilizing the reflection and diffraction of ultrasonic waves, they can perform non-destructive testing on non-metallic materials and components such as concrete and plastics to determine whether there are defects inside and on the surface of the materials.
[0004] However, the above equipment also has disadvantages during use. For example, when performing double-sided detection on a concrete structure, users need to draw grid lines on the detection wall of the concrete to determine the detection points, apply coupling agent at the detection points, and then hold the transducer with both hands at the same horizontal position on the same side for detection. Other personnel are also required to cooperate in operating the instrument to collect data. The number of detection points needs to be set at least 20 groups or more, resulting in a large workload, low work efficiency, and high labor costs, which is not conducive to the efficient detection of concrete structures. Therefore, a new detection device is urgently needed to solve this problem. Summary of the Utility Model
[0005] The main purpose of the utility model is to provide a device for detecting internal defects of highway concrete structures, which solves the disadvantages that existing tourist stools and luggage bags cannot be conveniently carried and used integrally.
[0006] The purpose of the utility model can be achieved by adopting the following technical solutions:
[0007] A device for detecting internal defects of highway concrete structures includes a base track and a vertical track slidably connected to the base track. An elevating slide rail is slidably installed in the inner channel of the vertical track. A slider is slidably connected to the inner wall of the elevating slide rail. One end of the slider is fixedly connected to a pick rod. One end of the pick rod is rotatably connected to a left-right threaded shaft, and a clamping sleeve is embedded on the outer wall of the other end of the pick rod.
[0008] Furthermore, both ends of the outer part of the elevating slide rail extend and slide in the inner wall of the vertical track, and a first connecting rod and a second connecting rod are welded. A handle is welded and fixed to the outer wall of the first connecting rod, and a motor is detachably installed on the outer wall of the second connecting rod.
[0009] Further, an operation panel is embedded in the inner wall of the handle, a storage battery is installed on the back of the operation panel, and the output end of the motor is connected to the positive and negative threaded shaft through a shaft sleeve.

[0011] Further, the detector body is placed in a storage rack welded to the outer wall of the pick rod.
[0012] Further, the slider is of a solid structure and the pick rod is of a hollow structure.
[0013] The beneficial technical effects of the present utility model:

[0020] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.
[0021] like Figures 1 - 3 As shown, a highway concrete structure internal defect detection device provided by the present embodiment includes a base rail 1, and a vertical rail 2 slidably connected to the base rail 1, a lifting rail 8 is slidably installed in the internal groove of the vertical rail 2, the base rail 1, the vertical rail 2 and the lifting rail 8 are all made of aluminum alloy, which reduces the weight of the device and is convenient for carrying and on-site operation. A slider 9 is slidably connected to the inner wall of the lifting rail 8, and the slider 9 slides in the inner wall of the lifting rail 8 to play a role of limiting guidance. One end of the outer side of the slider 9 is fixedly connected to a cantilever rod 3, and the spacing between the cantilever rods 3 is set to 1 meter, so that a concrete structure column with a width of 1 meter can be detected. The structure column can be square or cylindrical, and one end of the cantilever rod 3 is rotatably connected to a positive and negative threaded shaft 7, and the positive and negative threads of the positive and negative threaded shaft 7 are the same length, which can drive the cantilever rods 3 on both sides to move toward each other when rotating, and a jacket 4 is embedded in the outer wall of the other end of the cantilever rod 3, and the jacket 4 is an elastic material, which can support the transducer to maintain stability.
[0022] like Figure 1 and Figure 2 As shown, the outer ends of the lifting slide rail 8 extend to slide in the inner wall of the vertical track 2, and are welded with a first connecting rod 16 and a second connecting rod 17. The outer wall of the first connecting rod 16 is welded and fixed with a handle 13. The user stands on one side and holds the handle 13 for detection, and watches the detection transducer 5 on one side align with the detection point in a top-down posture. At this time, the transducer on the other side is synchronously aligned with the point of the observation position. The outer wall of the second connecting rod 17 is detachably mounted with a motor 6. The second connecting rod 17 is used to fix the motor 6 so that it has an external support structure. The motor 6 is connected to the operation panel 14 in the handle 13.
[0023] like Figure 3 As shown, an operation panel 14 is embedded in the inner wall of the handle 13, a battery 15 is installed on the back of the operation panel 14, the output end of the motor 6 is connected to the forward and reverse threaded shaft 7 through a sleeve, the battery 15 can meet the working needs of the electrical equipment on the device, and the buttons of the operation panel 14 are convenient for the user to operate with fingers extended when holding the handle 13 with one hand.
[0024] like Figure 1 and Figure 2As shown, the detection transducer 5 is clamped inside the jacket 4. The connection line 12, which penetrates the pick rod 3 and the jacket 4, is movably inserted into the back of the detection transducer 5. The end of the connection line 12 is inserted into the detector body 11. The detection transducer 5 is the signal output end and signal acquisition end structure of the ultrasonic detector. The detector body 11 generates ultrasonic signals through the piezoelectric effect. When these signals propagate through the material, they will be reflected and scattered when encountering defects. After the reflected and scattered signals are received by the ultrasonic transducer, they are processed and analyzed by the signal processing unit, and finally the internal situation of the material is displayed on the display screen.
[0025] As Figure 1 and Figure 2 shown, the detector body 11 is placed inside the storage rack 10 welded to the outer wall of the pick rod 3. The storage rack 10 is convenient for placing the detector body 11, making it close to the user for convenient synchronous operation.
[0026] As Figure 1 and Figure 2 shown, the slider 9 is a solid structure, and the pick rod 3 is a hollow structure. The solid structure of the slider 9 is convenient for keeping the pick rod 3 under pressure on the left - right threaded shaft 7, so that when the left - right threaded shaft 7 rotates, the pick rod 3 is moved using the screw drive principle. The hollow structure of the pick rod 3 is to reduce the weight of the device.
[0027] The working principle of this device:
[0028] The first step: This device is suitable for detecting concrete structural columns with a certain width. The structural column can be a square structure or a cylindrical structure. The detector body 11 is clamped on the storage rack 10, and the detection transducer 5 is clamped in the jacket 4. The back passes through the connection line 12 and is connected to the detector body 11. On both side walls of the concrete structural column to be detected, detection grid lines are drawn to determine the detection points. Coupling agent is applied at the detection points. The base track 1 is placed on both sides of the concrete structural column, and the base track 1 is visually fine - tuned to make it symmetrical on both sides of the structural column.
[0029] The second step: During detection, hold the handle 13 and move it back and forth to detect the points on the horizontal grid line. The user looks down from one side of the concrete structural column to align the detection transducer 5 with the detection point. The operation panel 14 starts the motor 6 to drive the left - right threaded shaft 7 to rotate. The pick rod 3 moves towards each other on the thread, and the slider 9 moves linearly in the lifting slide rail 8. The detection transducers 5 on both sides approach the detection point synchronously and contact the coupling agent. The user can operate the detector body 11 with the other hand to collect detection data. Control the motor 6 to rotate in the reverse direction, the detection transducers 5 separate, and push the vertical track 2 to move horizontally on the base track 1 to detect the next set of points.
[0030] Step 3: When replacing the horizontal line position, the handle 13 moves the lifting slide rail 8 through the first connecting rod 16 to slide within the vertical track 2, and visually determine that the detection transducer 5 is aligned with the position. Conduct such cyclic detection until the position detection is completed.
[0031] The above are only further embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the scope disclosed by the present utility model, according to the technical solution and its concept of the present utility model, makes equivalent replacements or changes, all belong to the protection scope of the present utility model.
