Description

Technical Field

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

[0002] Currently, urban roads, highways, and other road surfaces are all paved with asphalt to form asphalt pavements. Due to the effects of traffic loads and natural factors, cracks will appear on the asphalt pavement. If the cracks are not repaired in time, they will cause potholes, which will cause deeper damage to the asphalt pavement. Therefore, it is necessary to use a crack detector to detect and treat roadbed cracks.

[0003] A patent search revealed a device for detecting roadbed cracks, as indicated by publication number "CN221167363U". This device uses a high-pressure gas exhaust system to remove gravel from road cracks, ensuring the accuracy of the detection. However, a drawback is that when the high-pressure gas removes the gravel, it can splash onto the outside of the detection rod, impacting it and potentially damaging it, thus affecting its normal use. Therefore, this invention designs a road crack detection device to solve these problems. Utility Model Content

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Through the mechanical linkage design, this utility model only requires the operator to turn on the first motor, which will cause the first motor to move along the direction of the square groove. This will cause the scraper to push the gravel at the crack to be misaligned with the crack, so as to prevent the gravel from coming into contact with the detection rod. Thus, by using the device in this application, not only is the detection rod protected, but the accuracy of the detection rod in detecting cracks is also ensured.

[0015] 2.

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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Example 1

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a highway crack detection device includes a base plate 1 and rollers 2. The rollers 2 are fixed at the four corners of the bottom of the base plate 1. A housing 3 is fixed at the top center of the base plate 1. A detector 4 is fixed at the top of the housing 3. A detector rod 5 fixed at the bottom of the detector 4 is fixedly inserted through the housing 3. A square groove 6 is integrally formed on the left side inside the housing 3. A mounting plate 7 is fixed on the top left side of the base plate 1. A drive assembly 8 is set outside the mounting plate 7. The drive assembly 8 includes a first motor 801 fixed on the left side outside the mounting plate 7. The first motor 801 is a geared motor. The output end of the first motor 801 rotates through the mounting plate 7. A rotating plate 802 is fixedly sleeved outside the output end of the first motor 801. A guide hole 803 is integrally formed inside the rotating plate 802. A connecting rod 804 is set inside the guide hole 803. The end of the connecting rod 804 away from the guide hole 803 is embedded in the square groove 6. A scraper 805 is rotatably sleeved outside the connecting rod 804.

[0026] A clearance hole 9 is integrally provided in the middle of the interior of the base plate 1. The clearance hole 9 is fitted onto the outside of the detection rod 5. The bottom of the detection rod 5 is higher than the bottom of the base plate 1. A limiting hole 10 is integrally provided on the left side of the interior of the base plate 1. A sliding plate 11 is slidably connected inside the limiting hole 10. The sliding plate 11 is slidably fitted onto the outside of the scraper 805. The guide hole 803 is a through hole design. The length of the guide hole 803 is greater than the side length of the square groove 6. A handle 12 is fixedly provided on the top right side of the base plate 1. The center of the output end of the first motor 801 coincides with the center of the square groove 6. The handle 12 has a U-shaped cross-section when viewed from the side. A lithium battery 13 is fixedly provided on the top right side of the base plate 1. The lithium battery 13 is connected to the first motor 801 and the detector 4 through wires.

[0027] The operator first pushes handle 12, causing handle 12 to move roller 2, base plate 1, detector 4, and detector rod 5 along the direction of the crack. This allows detector 4 to control detector rod 5 to inspect the crack. Additionally, the operator can activate the first motor 801, which drives rotating plate 802 to move connecting rod 804 along the direction of square groove 6. At this time, connecting rod 804 is in a state of rotating and displacing within guide hole 803, ensuring the normal displacement of connecting rod 804 within square groove 6 by rotating plate 802. When connecting rod 804 drives scraper 805 along the transverse direction of square groove 6... When moving, the scraper 805 drives the slide plate 11 to move along the direction of the limiting hole 10. When the connecting rod 804 drives the scraper 805 to move along the longitudinal direction of the square groove 6, the scraper 805 moves up and down along the direction of the slide plate 11. In this way, the scraper 805 repeatedly pushes the gravel at the crack to the outside of the crack, which not only prevents the gravel from blocking the crack, but also prevents the gravel from contacting the detection rod 5. At the same time, the lifting design of the scraper 805 can prevent the scraper 805 from contacting the ground during reset, which would cause the gravel on the ground to be pushed back to the crack by the scraper 805, thus ensuring the effect of gravel removal. The clearance hole 9 clears the detection range of the detection rod 5.

[0028] Example 2

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, an observation hole 14 is integrally provided at the front end of the inner shell 3. The observation hole 14 is a through hole. A baffle 15 is provided on the left side of the front end of the inner shell 3 via a hinge and on the right side via a latch. The second motor 16 is fixedly connected to the base plate 1 inside the shell 3. The second motor 16 is connected to the lithium battery 13 via a wire. The output end of the second motor 16 is externally fixedly sleeved on the drive gear 17. The second motor 16 is a servo motor with a self-locking function. The second motor 16 stops running after rotating 180 degrees. A pivot pin 18 is rotated to the right side inside the base plate 1. A partition 19 is fixedly sleeved on the outside of the pivot pin 18. The top surface of the partition 19 is in contact with the bottom surface of the base plate 1. The driven gear 20 is fixedly sleeved on the upper part of the pivot pin 18 and meshes with the gear teeth of the drive gear 17. The diameter of the drive gear 17 is the same as the diameter of the driven gear 20.

[0030] According to the operation method in Embodiment 1, after the crack detection is completed, the staff can turn on the second motor 16. The second motor 16 drives the driving gear 17 to control the driven gear 20 together with the pivot pin 18 and the partition plate 19 to rotate 180 degrees and then stop running. At this time, the partition plate 19 and the clearance hole 9 overlap each other, thereby isolating the detection end of the detection rod 5 from the outside world and protecting the appearance of the detection rod 5. In addition, the staff can open the baffle 15 and perform maintenance on the detection rod 5 and the second motor 16 through the observation hole 14.
