Description

Technical Field

[0001] This utility model relates to the field of road surface crack detection technology, and in particular to a road and bridge pavement crack detection device. Background Technology

[0002] Road and bridge pavement crack detection equipment is used in the construction and operation stages of roads and bridges. It can improve detection efficiency and accuracy, realize early warning, and facilitate data traceability and analysis. Because it can ensure traffic safety, extend the service life of roads and bridges, and meet industry standards, it has become an indispensable detection tool for road and bridge engineering.

[0003] Road and bridge pavement crack detection equipment generally consists of a display screen, operation panel, storage device, processor, and other structures. The equipment uses a camera and light source to collect pavement images, which are then transmitted to a data processing device via a data cable or wireless module. Software algorithms are used to process and analyze the data to extract crack features and combine them with positioning information for precise location. Finally, the results are displayed on the operation interface. Meanwhile, positioning navigation, mechanical transmission, and power supply devices work together to ensure the efficient and accurate operation of the equipment.

[0004] Existing road and bridge pavement crack detection equipment cannot effectively store and protect the detection head, making it susceptible to physical damage when not in use. During transportation, storage, or construction, the head is prone to collisions with external objects, causing lens breakage and sensor damage, affecting the normal operation and detection accuracy of the equipment. Long-term exposure exposes the head to environmental erosion such as dust, rainwater, and sandstorms. Dust accumulation, rainwater infiltration, and sandstorm abrasion reduce the quality of collected data, thus affecting detection accuracy. Therefore, a new road and bridge pavement crack detection device is proposed to solve the above problems. Utility Model Content

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figure 1 , Figure 2 and Figure 5The present invention provides an embodiment of a road and bridge pavement crack detection device, including a detection device 1. The detection device 1 adopts a high-strength structure with good seismic performance to ensure stable operation in complex road and bridge inspection environments. A display panel 2 is fixedly connected to its front end. The display panel 2 is a high-resolution liquid crystal display screen that can clearly display detection data, images and various status information of the device, which is convenient for staff to read and analyze in real time.

[0034] The front end of the detection device 1 is also fixedly connected with multiple control buttons 3. These control buttons 3 have obvious tactile feedback, are reasonably laid out, and are easy for operators to operate. They can easily realize functions such as starting, stopping, and setting parameters of the equipment. The rear side of the detection device 1 is fixedly connected with a protective shell 16. The protective shell 16 has a semi-enclosed structure, which can effectively block external dust, debris, etc., to avoid interference or damage to the internal structure and provide reliable protection for the internal structure. The protective shell 16 is fixedly connected with a fixing block 12. The fixing block 12 plays a role in stabilizing support and ensuring the stability of the parts connected to it. The fixing block 12 is rotatably connected with two clamps 13. The clamps 13 can rotate flexibly. When the detection head 17 is placed in it, it can be tightly attached to the detection head 17 under the action of the second spring 18 to prevent it from shaking.

[0035] The clamping plate 13 is internally rotatably connected to a component plate 14, which helps the clamping plate 13 better adapt to the shape of the detection head 17 and further improves the fixing effect of the detection head 17. The clamping plate 13 is fixedly connected to a fixing disk 15 on the outside. The fixing disk 15 moves synchronously during the rotation of the clamping plate 13 and is used to transmit force. The fixing disk 15 is internally fixedly connected to a second spring 18. The second spring 18 has good elasticity, stores energy when compressed, and can quickly rebound when released, driving the clamping plate 13 to reset. The other end of the second spring 18 is fixedly connected to the outside of the fixing block 12, thus forming a stable elastic connection structure to ensure the normal operation of the clamping plate 13. The detection device 1 is fixedly connected to a first transmission line 4 on the outside. The first transmission line 4 is responsible for signal transmission and effectively connects the detection device 1 to the shrinking assembly to ensure the stability and accuracy of data transmission. The other end of the first transmission line 4 is fixedly connected to the shrinking assembly.

[0036] Reference Figure 1 , Figure 3 and Figure 4The retraction component includes a second transmission line 8, which has good flexibility and can slide smoothly within the housing 5 as the detection head 17 is stretched and contracted, while ensuring that signal transmission is not affected. The other end of the second transmission line 8 is fixedly connected to the detection head 17, which is used to directly contact the road and bridge surface to collect data related to cracks. It has a high-precision sensor that can accurately detect information such as the width and depth of cracks. One end of the second transmission line 8 is fixedly connected to one end of the first transmission line 4, realizing a complete path for the signal to be transmitted from the detection head 17 through the second transmission line 8 to the first transmission line 4, and finally to the detection device 1. A first spring 7 is fixedly connected inside the second transmission line 8. The first spring 7 has strong elastic restoring force and can provide a reverse tension after the second transmission line 8 is stretched, realizing the automatic retraction of the second transmission line 8. A fixing post 6 is fixedly connected inside the first spring 7, which provides stable support for the first spring 7 and ensures that it remains stable during the extension and contraction process without displacement or twisting.

[0037] The other end of the fixed post 6 is fixedly connected to the outer shell 5. The outer shell 5 serves to protect the internal structure and provides space for the installation and movement of components such as the connecting plate 9 and the limiting shell 10. The outer side of the outer shell 5 is slidably connected to the outer side of the detection device 1, allowing the shrinking assembly to move flexibly relative to the detection device 1 to adapt to different detection requirements. The outer side of the transmission line 8 is slidably connected to the inside of the outer shell 5, ensuring smooth sliding of the transmission line 8 within the outer shell 5 and preventing external interference. The outer side of the fixed post 6 is rotatably connected to the connecting plate 9. The connecting plate 9 can rotate flexibly within the outer shell 5 under the pull of the transmission line 8. Its rotation drives the movement of the ball bearing 11. The outer side of the connecting plate 9 is textured, and these textures cooperate with the ball bearing 11 to lock and unlock the rotation position of the connecting plate 9.

[0038] A ball bearing 11 is rotatably connected to the outer side of the connecting disc 9. The ball bearing 11 rolls as the connecting disc 9 rotates. When the tension of the second transmission line 8 stops, the ball bearing 11 will be engaged in the groove of the connecting disc 9 under the action of the first spring 7, preventing the connecting disc 9 from rotating in the opposite direction, thereby fixing the length of the second transmission line 8. A limiting shell 10 is slidably connected to the outer side of the ball bearing 11. The limiting shell 10 restricts the movement trajectory of the ball bearing 11, ensuring that it is always within the range of action of the connecting disc 9, and at the same time preventing the ball bearing 11 from falling out. The outer side of the limiting shell 10 is slidably connected to the outer side of the outer shell 5, and works in cooperation with the outer shell 5 to provide a stable working environment for the ball bearing 11 and the connecting disc 9. A sliding groove is opened inside the limiting shell 10, which provides a track for the sliding of the ball bearing 11, ensuring the accuracy and stability of the movement of the ball bearing 11.

[0039] Working principle: When workers need to inspect cracks in the ground, they can open the protective shell 16, remove the detection head 17 from the inside of the two clamping plates 13, place the detection head 17 on the location to be inspected, and then start the detection device 1 through the control button 3. The ground can then be inspected through the detection head 17. When the detection head 17 needs to be stored, it can be placed back inside the two clamping plates 13. When the detection head 17 slides to the outside of the clamping plates 13, it will squeeze the clamping plates 13 to both sides, causing the fixing plate 15 connected to the outside of the clamping plates 13 to squeeze the second spring 18. When the detection head 17 slides to the inside of the clamping plates 13, the squeezed spring 18 will push the clamping plates 13 back to their original position, thereby restricting the detection head 17.

[0040] When the operator needs to extend the detection head 17, the transmission line 8 can be pulled through the detection head 17, extending it out from inside the housing 5. This extension of the transmission line 8 causes the other end of the transmission line 8 to pull the connecting plate 9, causing the connecting plate 9 to rotate inside the housing 5. The rotation of the connecting plate 9 then moves the ball bearing 11 along with it. The side of the connecting plate 9 that contacts the ball bearing 11 has textured surfaces. Once the detection head 17 has reached its full length, the pulling can be stopped. At this point, the spring 7... This will drive the transmission line 2 8, causing it to rotate in the opposite direction, which in turn causes the limiting shell 10 to rotate in the opposite direction as well. At this time, the ball bearing 11 will rotate into the groove of the connecting plate 9, thereby locking the connecting plate 9 to maintain the length pulled out by the detection head 17. When it is necessary to retract the transmission line 2 8, it can be gently pulled outward, causing the connecting plate 9 to rotate and the ball bearing 11 to rotate out from the groove on the outside of the connecting plate 9. At this time, the spring 1 7 will pull the transmission line 2 8 into the inside of the outer shell 5, thereby realizing the storage of the transmission line 2 8.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
