Description

Technical Field

[0001] This utility model relates to the field of concrete testing, specifically to a concrete crack detection device. Background Technology

[0002] Concrete technology is widely used in highways, bridges, engineering projects, underground tunnels, and various building fields. Under the long-term effects of impact loads, fatigue loads, and the external environment, coupled with the inherent defects in the properties of concrete materials, cracking of cement concrete is an unavoidable phenomenon. It can easily damage the integrity of highway, bridge, engineering project, underground tunnel, and various building structures, change the stress conditions, and cause significant safety hazards. Therefore, relevant equipment is needed to detect concrete cracks.

[0003] Traditional concrete crack detectors are mostly handheld devices. When inspecting concrete cracks at higher locations, they require the user to hold the device up with their arm. Prolonged use of these devices is physically demanding and can easily cause damage to the elbows and arm muscles. Furthermore, prolonged manual operation can cause hand tremors, leading to the device shaking and potentially coming into contact with the crack, thus damaging the equipment. Additionally, these devices cannot be easily repositioned to detect cracks at higher locations, on side walls, or on the bottom, resulting in low adaptability. When not in use, they are exposed to the elements without any protective devices, making them susceptible to damage during transport. Utility Model Content

[0004] To address the problems of traditional concrete crack detectors, which are mostly handheld devices that require arm support to inspect high-level cracks, prolonged use is physically demanding and can easily cause elbow and arm muscle damage. Furthermore, hand tremors during extended operation can cause the device to shake, potentially leading to contact with the crack and damage. Additionally, the device lacks flexibility in repositioning to different locations (high, side, or bottom cracks), resulting in low adaptability. When not in use, it is exposed to the elements without protective devices, making it susceptible to damage during transport. Therefore, this invention provides a concrete crack detection device.

[0005] A concrete crack detection device includes a mobile frame with a through groove and a support frame. A protective cover and a base plate are movably mounted on the top and inside of the through groove, respectively. A reciprocating screw is rotatably mounted on the support frame, and a detection component is threadedly connected to the outer wall of the reciprocating screw. The detection component includes a rotating block, on which a detection probe is fixedly mounted. Illumination lamps and an image acquisition device are respectively mounted on both sides and above the detection probe. A display control panel is also fixedly mounted on the support frame.

[0006] More preferably, the mobile frame includes a top plate and casters. A through slot is provided through the top plate, and two interconnected receiving slots are provided inside the top plate. One receiving slot is movably provided with a bottom plate, and the other receiving slot is rotatably provided with a gear. Limiting slots are fixedly provided on the side walls of the receiving slots on both sides of the bottom plate, and the bottom plate can move inside the limiting slots. A rack is fixedly provided on the top wall of the bottom plate, and the rack and gear are meshed and connected to each other. The central shaft of the gear passes through the side wall of the receiving slot and an adjustment knob is fixedly provided on its outer end.

[0007] More preferably, the support frame is fixedly installed on the top wall of the top plate, the display control panel is fixedly installed on its back, and a storage frame is also provided below the display control panel. A push rod is fixedly installed at the top of the storage frame, which can easily push the mobile frame forward.

[0008] More preferably, a groove is fixedly provided on the front of the support frame, a reciprocating screw is rotatably mounted on the groove, and a servo motor is fixedly mounted through the groove at its top end. Another limiting groove is fixedly provided on the side wall of the groove. The detection component includes a moving block, which passes through the reciprocating screw and is threadedly connected to its outer wall. The inner end of the moving block is slidably mounted inside the other limiting groove, and a rotating shaft is rotatably mounted on the outer end of the moving block. The rotating block is fixedly mounted on the outer wall of the rotating shaft, and another adjusting knob is fixedly mounted on one end of the rotating shaft.

[0009] More preferably, there are two lights, which are fixedly mounted on rotating blocks on both sides of the detection probe. The image acquisition unit is fixedly mounted on the rotating block above the detection probe. The display control panel is electrically connected to the servo motor, the two lights, the detection probe, and the image acquisition unit.

[0010] More preferably, one end of the protective cover is rotatably mounted on the top wall of the top plate, and the bottom wall of the other end and the corresponding position of the top wall of the top plate are both provided with matching magnet blocks. A hand pull ring is also fixedly installed on the top wall of the protective cover.

[0011] Compared with existing technologies, the advantages of this invention are: by utilizing the up-and-down movement of the detection component on the reciprocating screw, it can adapt to crack detection at different heights. Simultaneously, the rotation of the rotating block allows the detection component to detect cracks on the side walls, bottom walls, and top walls. Combined with a lighting lamp and image acquisition device, crack detection can be achieved more clearly, and it can adapt to dark detection environments. The storage frame can store other accessories needed for detection. During transportation, the detection component can be placed between the protective cover and the base plate, protecting it from collision damage. Attached Figure Description

[0022] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments of the present invention can be combined with each other. The following will refer to the accompanying drawings. Figures 1-5 The present invention will be described in detail with reference to the embodiments.

[0023] A concrete crack detection device includes a mobile frame 1, which includes a top plate 13 and casters 14. The mobile frame 1 is provided with a through groove 2 and a support frame 3. The through groove 2 passes through the top plate 13. The support frame 3 is fixedly installed on the top wall of the top plate 13. A display control panel 12 is fixedly installed on the back of the support frame 3. A storage frame 20 is also provided below the display control panel 12. A push rod 21 is fixedly installed at the top of the storage frame 20, which can easily push the mobile frame 1 forward.

[0024] Pushing the push rod 21 can move the caster wheel 14 forward, thereby pushing the mobile frame 1 forward. Personal items can be placed in the storage box 20 to reduce the burden on employees. When it is necessary to detect cracks on the ground, the detection probe 9 is pointed downwards to detect the cracks below through the through groove 2.

[0025] The top and inside of the through groove 2 are respectively provided with a protective cover 5 and a bottom plate 4. The top plate 13 is also provided with two interconnected receiving grooves 15. One of the receiving grooves 15 is provided with a bottom plate 4. The bottom plate 4 can play a protective shielding role below the detection component 7.

[0026] Another receiving groove 15 is rotatably equipped with a gear 16. The side walls of the receiving grooves 15 on both sides of the base plate 4 are fixedly provided with limiting grooves 17. The base plate 4 can move inside the limiting grooves 17. The top wall of the base plate 4 is fixedly provided with a rack 18. The central shaft of the gear 16 passes through the side wall of the receiving groove 15 and an adjustment knob 19 is fixedly provided at the outer end.

[0027] By turning the adjustment knob 19, the gear 16 can be rotated. Since the rack 18 and the gear 16 are meshed together, the rotation of the gear 16 can drive the rack 18 to move left and right, thereby driving the base plate 4 to move left and right along the limiting groove 17, thus blocking or allowing passage through the through groove 2. When blocking, it can protect the bottom of the detection component 7, and when passing through, it can facilitate the detection component 7 to detect the cracks below.

[0028] One end of the protective cover 5 is rotatably mounted on the top wall of the top plate 13, and the bottom wall of the other end and the corresponding position on the top wall of the top plate 13 are both equipped with matching magnet blocks 25. A pull ring 27 is also fixedly mounted on the top wall of the protective cover 5. After the detection component 7 enters the protection range of the protective cover 5, pulling the pull ring 27 can rotate the protective cover 5 to cover the detection component 7. The magnet blocks 25 can attract each other, thus allowing for quick opening and closing of the view. The side of the protective cover 5 that contacts the moving block 23 is provided with a groove, and the crossbar of the moving block 23 can be movably engaged in the groove.

[0029] Since the display control panel 12 is electrically connected to the servo motor 26, the two lights 10, the detection probe 9, and the image acquisition unit 11, the information detected by the detection probe 9 and the image acquisition unit 11 and the images captured can be seen on the display control panel 12. The display control panel 12 can also control the servo motor 26 to start according to the detection environment, so that the detection component 7 can be adjusted according to the position and height of the crack. The two lights 10 can also be switched on and off freely for better detection.

[0030] A reciprocating screw 6 is rotatably mounted on the support frame 3. A detection component 7 is threadedly connected to the outer wall of the reciprocating screw 6. The detection component 7 includes a rotating block 8. A groove 22 is fixedly provided on the front of the support frame 3. The reciprocating screw 6 is rotatably mounted on the groove 22, and a servo motor 26 is fixedly provided through the groove 22 at its top end. Another limiting groove 17 is fixedly provided on the side wall of the groove 22. The detection component 7 includes a moving block 23, which passes through the reciprocating screw 6 and is threadedly connected to its outer wall. The inner end of the moving block 23 is slidably disposed inside the other limiting groove 17. Activating the servo motor 26 can drive the reciprocating screw 6 to rotate, thereby driving the moving block 23 to move up and down along the direction of the limiting groove 17 to meet the needs of crack detection at different heights.

[0031] A rotating shaft 24 is rotatably mounted on the outer end of the movable block 23. A rotating block 8 is fixedly mounted on the outer wall of the rotating shaft 24. Another adjusting knob 19 is fixedly mounted on one end of the rotating shaft 24. A detection probe 9 is fixedly mounted on the rotating block 8. Illumination lamps 10 and an image acquisition device 11 are respectively mounted on the sides and above the detection probe 9. There are two illumination lamps 10, fixedly mounted on the rotating blocks 8 on both sides of the detection probe 9. The image acquisition device 11 is fixedly mounted on the rotating block 8 above the detection probe 9.

[0032] The detection probe 9 is a common crack detection probe in existing technology, and the image acquisition device 11 can be an image acquisition structure such as a camera. When it is necessary to adjust the flip detection direction according to the location of the crack, turn the adjustment knob 19 to rotate the catheter rotation shaft 24, which can drive the rotating block 8 to rotate forward, upward, and downward, thereby adjusting the detection direction. Furthermore, if the environment is dim when the detection probe 9 is performing crack detection, the illumination lamp 10 can be turned on to provide clearer image acquisition by the image acquisition device 11. The real-time image acquired by the image acquisition device 11 can be compared with the data detected by the detection probe 9 to avoid detection errors.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
