Abstract
Description
Technical Field
[0001] This application relates to the technical field of road crack detection, and in particular to a road crack detection device for highway engineering. Background Technology
[0002] Detection equipment can detect cracks when they are still in their tiny stages, promptly alerting maintenance departments to take action. Ground-penetrating radar is commonly used to detect tiny cracks that have just appeared inside the road base. These cracks may not yet show obvious signs on the road surface. Early detection and treatment can prevent the damage from developing further, avoiding small cracks from gradually expanding into large cracks, or even causing serious consequences such as road collapse.
[0003] A search revealed Chinese Patent Publication No. CN214334850U, which discloses a road crack detection device. In use, simply pushing the handle moves the device forward to inspect the road. During inspection, a motor drives a rotating screw, causing the detection probe on the slider to move left and right, inspecting the road surface located under the support plate. This simplifies the inspection process and makes it easier for workers to operate. The design is simple and convenient, solving the problem of cumbersome manual handheld operation and preventing missed detections caused by manual changes in the inspection position.
[0004] Regarding the aforementioned related technologies, the inventors have discovered the following drawbacks: In existing technologies, when conducting road inspections or subsequent maintenance work, workers generally need to pause the inspection and manually bend over to mark the location of cracks, which increases the workload of workers and reduces the efficiency of inspections. In order to solve the problem of workers manually marking the location of cracks in existing technologies, which increases the labor intensity of workers, this application proposes to set up a liftable mold on the device, thereby facilitating workers to quickly mark the location of cracks, thereby reducing the labor intensity of workers and improving work efficiency. Utility Model Content
[0005] To facilitate the rapid marking of crack locations by staff, thereby reducing their workload and improving work efficiency, this application provides a road crack detection device for highway engineering.
[0006] This application provides a road crack detection device for highway engineering, which adopts the following technical solution: it includes a base and a bracket. A detection component is installed on the base. The bracket is rotatably installed on the base. A fixing box is provided on one side of the base. A connecting component is provided between the fixing box and the bracket. A template is slidably provided at the lower end of the fixing box. A sponge pad is provided between the template and the fixing box.
[0007] Optionally, two vertical rods are installed on the upper end of the template, the upper ends of the two vertical rods pass through the fixing box, and fixing caps are provided on the vertical rods, with the fixing caps threadedly connected to the vertical rods.
[0008] Optionally, the connecting assembly includes a fixing rod and a vertical plate. The fixing rod is mounted on the bracket, one end of the vertical plate is rotatably mounted on the fixing rod via a connecting shaft, and the other end of the vertical plate is rotatably connected to the fixing box via a rotating shaft.
[0009] Optionally, a drive rod is provided on one side of the connecting shaft. One end of the drive rod is rotatably connected to the bracket via a connecting rod, and the other end of the drive rod is rotatably mounted on the fixed rod. Both the drive rod and the connecting shaft are provided with bevel gears, and the two bevel gears mesh for transmission.
[0010] Optionally, a torsion spring is fitted onto the drive rod, with one end of the torsion spring mounted on the drive rod and the other end mounted on the connecting rod.
[0011] Optionally, the upper part of the fixing box is provided with a liquid replenishment hole, and there are two liquid replenishment holes, which are symmetrically arranged on the fixing box.
[0012] Optionally, the detection component includes a placement box mounted on the base, and a ground-penetrating radar is disposed inside the placement box.
[0013] In summary, this application includes the following beneficial technical effects:
[0014] 1. This utility model, by incorporating components such as a fixed box, a template, and a sponge pad, allows workers to move the base via a support during operation, which in turn moves the ground-penetrating radar. Upon detecting a crack, the device moves the template above the crack, then drives the support to rotate. The support, through connecting components, moves the fixed box downwards, which in turn moves the template downwards. As the template contacts the ground, it compresses the sponge pad, causing the marking liquid in the sponge pad to flow out from the template gaps. This achieves rapid marking of the crack, reducing the labor intensity of workers and improving work efficiency.
[0015] 2. This utility model is equipped with components such as a drive rod, bevel gear, connecting shaft, and torsion spring. During operation, the drive rod, bevel gear, and connecting shaft cooperate to adjust the rotation of the drive rod, thereby driving the placement box to rotate and adjusting the angle of the placement box so that the direction of the notes is consistent with the direction of the crack, which facilitates subsequent operation by the staff. While the drive rod rotates, it also drives the torsion spring to work. When the staff releases the drive rod, the torsion spring automatically resets the drive rod. Attached Figure Description

[0021] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.
[0022] This application discloses a road crack detection device for highway engineering. For example... Figure 1 As shown, the system includes a base 1 and a support 2. A detection component is installed on the base 1. The detection component includes a placement box 3, which is mounted on the base 1. A ground-penetrating radar is installed inside the placement box 3. The ground-penetrating radar transmits high-frequency electromagnetic waves into the ground through a transmitting antenna. These electromagnetic waves propagate in the underground medium. When they encounter the interface between different media, the electromagnetic waves will undergo reflection, refraction, and scattering due to the different electromagnetic properties of the different media. The reflected waves will be received by the receiving antenna. After signal processing and analysis, the structure of the underground medium and the location, size, shape, and properties of the target object can be inferred based on the time, amplitude, frequency, and phase information of the reflected waves.
[0023] Combination Figure 1 , Figure 2 As shown, the bracket 2 is rotatably mounted on the base 1. A fixing box 7 is provided on one side of the base 1. A connecting component is provided between the fixing box 7 and the bracket 2. The connecting component includes a fixing rod 4 and a vertical plate 5. The fixing rod 4 is mounted on the bracket 2. One end of the vertical plate 5 is rotatably mounted on the fixing rod 4 through a connecting shaft 6. The other end of the vertical plate 5 is rotatably connected to the fixing box 7 through a rotating shaft 8.
[0024] Combination Figure 2 , Figure 3As shown, a drive rod 14 is provided on one side of the connecting shaft 6. One end of the drive rod 14 is rotatably connected to the bracket 2 through the connecting rod 15, and the other end of the drive rod 14 is rotatably mounted on the fixed rod 4. A torsion spring 17 is sleeved on the drive rod 14. One end of the torsion spring 17 is mounted on the drive rod 14, and the other end of the torsion spring 17 is mounted on the connecting rod 15. When the operator adjusts the drive rod 14 to rotate, the drive rod 14 drives the torsion spring 17 to rotate and store force. When the operator releases the drive rod 14, the torsion spring 17 drives the drive rod 14 to automatically reset.
[0025] See Figure 1 , Figure 3 As shown, both the drive rod 14 and the connecting shaft 6 are equipped with bevel gears 16. The two bevel gears 16 mesh to drive the transmission. The template 10 is slidably mounted on the lower end of the fixed box 7. When the drive rod 14 rotates, it drives the bevel gears 16 to rotate. The meshing between the two bevel gears 16 drives the connecting shaft 6 to rotate. The connecting shaft 6 drives the vertical plate 5 to rotate. The vertical plate 5 drives the fixed box 7 to rotate. The fixed box 7 drives the template 10 to rotate, thereby adjusting the angle of the template 10 and achieving the effect that the direction of the template 10 is consistent with the direction of the crack.
[0026] See Figure 4 As shown, two vertical rods 11 are installed on the upper end of the template 10. The upper ends of the two vertical rods 11 pass through the fixing box 7. Fixing caps 12 are provided on the vertical rods 11. The fixing caps 12 are threadedly connected to the vertical rods 11. By removing the fixing caps 12 from the vertical rods 11, the restriction on the template 10 is removed, so that the template 10 can be replaced, thereby improving the applicability of the device.
[0027] A sponge pad 9 is provided between the template 10 and the fixing box 7. The upper part of the fixing box 7 is provided with a liquid replenishment hole 13. There are two liquid replenishment holes 13, which are symmetrically arranged on the fixing box 7. The liquid replenishment hole 13 facilitates the real-time replenishment of the marking liquid to the sponge pad 9, avoiding the cumbersome steps of disassembly and replenishment, and improving work efficiency.
[0028] The implementation principle of a road crack detection device for highway engineering in this application embodiment is as follows: When inspecting the road surface, the staff pushes the base 1 to move through the bracket 2. The base 1 drives the ground penetrating radar to move accordingly and detects the ground through the ground penetrating radar. When a crack is detected, the staff pushes the device again through the bracket 2 and moves the template 10 above the crack. Then, one end of the bracket 2 is pressed down, and the bracket 2 drives the vertical plate 5 to move downward through the connecting shaft 6. The vertical plate 5 drives the fixing box 7 to move accordingly. The fixing box 7 drives the template 10 to move towards the ground and make contact with the ground. Then, one end of the bracket 2 moves downward, and the template 10 and the fixing box 7 squeeze the sponge pad 9. At this time, the marking liquid in the sponge pad 9 flows out from the gap of the template 10, realizing rapid marking of the ground.
[0029] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
