Description

Technical Field

[0001] This utility model relates to a road marking detection device, belonging to the field of road marking detection technology. Background Technology

[0002] Road marking inspection is crucial for ensuring road traffic safety. Comprehensive inspection items and strict quality control standards ensure the quality and standardization of markings, reducing traffic accidents caused by marking issues. Furthermore, inspections provide road management departments with scientific data to guide the maintenance and management of road markings.

[0003] CN201822192924.2 discloses a laser detection device for road markings, including a telescopic rod installed at the bottom of a vehicle chassis, the other end of which is connected to a laser. Distance sensors are installed on the vehicle wheels. Both the laser and the distance sensors are connected to an information collector via wires, and the information collector is connected to a computer via wires.

[0004] The technical solution disclosed in the aforementioned patent documents uses a laser to scan the length and width of road markings and records their wear and tear, greatly facilitating road marking maintenance. However, practical experience has shown that this solution still has the following technical problems: it can only detect single-lane road markings; for two-lane or three-lane road markings, multiple back-and-forth movements of the vehicle are required for complete detection, resulting in low detection efficiency and significant room for improvement in its applicability.

[0005] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0006] This invention addresses the shortcomings of the prior art by providing a road marking detection device that can effectively detect not only single-lane markings but also two-lane or three-lane road markings simultaneously, significantly improving the efficiency of road marking detection and broadening its application scope.

[0007] To solve the above technical problems, the present invention adopts the following technical solution:

[0008] The road marking detection device includes a main arm, which is mounted horizontally to the front of the vehicle body via a connecting seat. A downward-facing main laser is installed at the lower part of both ends of the main arm along its length. Two staggered auxiliary arms are installed inside the main arm. Both the main arm and the auxiliary arms are hollow structures. The auxiliary arms are connected to the main arm via telescopic cylinders. One end of the auxiliary arm extends out from inside the main arm, and a downward-facing auxiliary laser is installed at the bottom of the extended end. The auxiliary laser and the main laser are at the same horizontal height.

[0009] Furthermore, the connecting seat is located above the middle position of the main arm.

[0010] Furthermore, a transverse partition is fixedly installed in the middle of the main arm cavity, and the transverse partition is arranged along the length direction of the main arm.

[0011] Furthermore, the diaphragm divides the main arm cavity into two sliding cavities arranged vertically, and a secondary arm arranged laterally is installed in each sliding cavity.

[0012] Furthermore, the telescopic cylinder is installed inside the auxiliary arm, and the two telescopic cylinders are arranged in opposite directions.

[0013] Furthermore, the head of the telescopic cylinder is connected to the inner wall of the auxiliary arm via a first fixed shaft. The head of the telescopic cylinder is hinged to the first fixed shaft, and the first fixed shaft is fixedly connected to the inner wall of the auxiliary arm.

[0014] Furthermore, the tail of the telescopic cylinder is connected to the inner wall of the main boom via a second fixed shaft. The tail of the telescopic cylinder is hinged to the second fixed shaft, and the second fixed shaft is fixedly connected to the inner wall of the main boom.

[0015] Furthermore, the auxiliary arm is provided with a first slip ring and a second slip ring at both ends along its length.

[0016] Furthermore, the first slip ring is fixedly connected to the end of the auxiliary arm, the outer ring of the first slip ring is slidably connected to the inner wall of the main arm, the second slip ring is fixedly connected to the inner side of the end of the main arm, and the inner ring of the second slip ring is slidably connected to the outer wall of the auxiliary arm.

[0017] Compared with the prior art, the present invention, by adopting the above technical solution, has the following advantages:

[0018] This invention is installed at the front of the vehicle body and moves synchronously with the vehicle body. During the vehicle's movement, the main laser and the auxiliary laser can scan the length and width of the road markings and record the wear and tear of the road markings. This invention can simultaneously detect road markings for single lanes, two lanes, and three lanes, greatly improving the detection of road markings and broadening its application scope.

[0019] When it is necessary to detect road markings on a single lane, only the main laser needs to work; when it is necessary to detect road markings on a two-lane road, one of the auxiliary lasers extends outward under the action of the telescopic cylinder, and the main laser and one of the auxiliary lasers work synchronously; when it is necessary to detect road markings on a three-lane road, both auxiliary lasers extend outward under the action of the telescopic cylinder, and the main laser and both auxiliary lasers work synchronously.

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments. Attached Figure Description

[0027] like Figures 1-4 As shown in the figure, this utility model provides a road marking detection device, including a main arm 1, which is installed horizontally at the front end of the vehicle body 3. A main laser 4 is installed at the lower part of both ends of the main arm 1 along the length direction, and two secondary arms 7 are installed inside the main arm 1 in an alternating manner. One end of the secondary arm 7 extends out from the inside of the main arm 1, and a secondary laser 11 is installed at the bottom of the extended end, which is positioned downwards. The secondary laser 11 and the main laser 4 are located at the same horizontal height.

[0028] The main arm 1 is fixedly connected to the vehicle body 3 via a connecting seat 2, which is located above the middle position of the main arm 1.

[0029] Both the main arm 1 and the auxiliary arm 7 are hollow structures. A transverse partition 5 is fixedly installed in the middle of the inner cavity of the main arm 1, and the transverse partition 5 is arranged along the length of the main arm 1.

[0030] The diaphragm 5 divides the inner cavity of the main arm 1 into two sliding cavities 6 arranged vertically, and the auxiliary arms 7 arranged horizontally are installed in the sliding cavities 6 respectively.

[0031] The auxiliary boom 7 and the main boom 1 are connected by telescopic cylinders 8, which are installed inside the auxiliary boom 7 and arranged in opposite directions. The telescopic cylinders 8 provide power for the sliding of the auxiliary boom 7 within the main boom 1.

[0032] The head of the telescopic cylinder 8 is connected to the inner wall of the auxiliary arm 7 via a first fixed shaft 9.
