Technical Field
[0001] This utility model relates to the technical field of road surface testing equipment, specifically to a road surface laser scanner-assisted testing vehicle with automatic cleaning function. Background Technology
[0002] In recent years, my country has made remarkable achievements in highway infrastructure construction, with the total mileage of highways exceeding 5.35 million kilometers and a basic expressway network taking shape. With the deepening of the "Transportation Powerhouse" strategy, the road maintenance concept has gradually shifted from "reconstruction over maintenance" to "equal emphasis on construction and maintenance." Data shows that in 2022 alone, the total length of highways under maintenance nationwide reached 5.35 million kilometers, accounting for 99% of the total mileage. As a core component of preventative maintenance, road surface inspection is facing unprecedented demands for technological upgrades.
[0003] Currently, vehicle-mounted 3D laser inspection equipment is the mainstream technology for road surface inspection (CN201810091282). Although it can achieve automatic road surface scanning and data visualization analysis, it faces significant technical bottlenecks in practical applications: Using the testing equipment requires the road surface to be dry and clean, free from cracks, water accumulation, or mud and sand; otherwise, the test data will be distorted. More problematic is the need for operators to constantly manually clean debris from the testing area. In case of unexpected situations (such as gravel suddenly obstructing the laser or water accumulation affecting measurements), not only is handling the situation time-consuming and labor-intensive, but it can also easily interrupt the testing process. Furthermore, if testing personnel spend a significant amount of time cleaning the test section, testing efficiency can be greatly reduced.
[0004] Therefore, in order to make the vehicle-mounted 3D laser scanning results more accurate and stable, it is necessary to develop a road laser scanner auxiliary test vehicle with automatic cleaning function. Utility Model Content
[0005] The purpose of this invention is to propose a road surface laser scanner-assisted test vehicle with automatic sweeping function to solve the technical defects pointed out in the background art.
[0006] To overcome the aforementioned technical deficiencies, the technical solution adopted by this utility model is as follows: A road surface laser scanner-assisted testing vehicle with automatic cleaning function includes a testing trolley and a cleaning mechanism disposed on the front side of the testing trolley in the direction of travel. The testing trolley has a receiving groove for installing testing equipment, and a vertically penetrating testing opening is formed in the middle of the receiving groove. The cleaning mechanism includes a cleaning receiving box, a cleaning roller brush disposed in the cleaning receiving box, a garbage collection box disposed in the cleaning receiving box for holding garbage, and a power component for driving the cleaning roller brush.
[0007] Furthermore, the detection trolley includes a trolley frame, a guide wheel assembly disposed at the bottom of the trolley frame, and a handrail disposed on the top surface of the trolley frame.
[0008] Furthermore, the trolley frame includes a transverse support frame and a longitudinal support frame, which together form the trolley frame, and the receiving groove is disposed inside the transverse support frame and the longitudinal support frame.
[0009] Furthermore, the guide wheel assembly includes guide wheel mounting plates disposed on the front and rear sides of the longitudinal support frame, a universal guide wheel disposed on the front guide wheel mounting plate, and a fixed guide wheel disposed on the rear guide wheel mounting plate. A handrail mounting seat is disposed on the rear guide wheel mounting plate, and the handrail is mounted on the handrail mounting seat.
[0010] Furthermore, the sweeping roller brush is rotatably mounted on the front side of the sweeping container, with the brush bristles protruding downwards. The waste collection bin is located on the rear side of the sweeping container. The sweeping roller brush drives the waste into the waste collection bin to form temporary storage. The power component is a drive motor, which is connected to the sweeping roller brush via a belt drive mechanism or a gear drive mechanism. The drive mechanism is located in the side cavity of the sweeping container. The waste collection bin is mounted inside the sweeping container via a snap-fit structure.
[0011] Furthermore, the cleaning mechanism is fixedly connected to the front end of the detection trolley via an electromechanical box. The electromechanical box and the trolley frame are detachably connected by bolts. A rechargeable battery pack is installed inside the electromechanical box, which supplies power to the cleaning mechanism and the detection equipment. The electromechanical box is equipped with a battery cover for easy installation and removal of the rechargeable battery pack, and a switch for controlling the power supply is correspondingly installed on the electromechanical box.
[0012] Furthermore, a wiper assembly is provided at the bottom of the front horizontal support frame. The wiper assembly includes a flexible wiper blade and a wiper blade frame. The flexible wiper blade is fixed to the wiper blade frame by a fastener, and the wiper blade frame is fixedly installed at the bottom of the horizontal support frame.
[0013] Furthermore, the flexible wiper blade is made of rubber.
[0014] Compared with the prior art, the present invention has the following beneficial effects: This invention proposes a road surface laser scanner-assisted testing vehicle with automatic cleaning function. It includes a testing trolley and a cleaning mechanism positioned at the front in the forward direction. The testing trolley has a receiving slot for accommodating the testing equipment and a testing opening in the center. The cleaning mechanism includes a cleaning receiving box, a cleaning roller brush, a waste collection box, and a drive motor. It is connected to the testing trolley via an electromechanical box and powered by a rechargeable battery pack. A squeegee assembly is also provided at the bottom of the front transverse support frame. This invention integrates the cleaning mechanism with the testing function to achieve real-time removal of road surface pollutants, avoiding interference from gravel, water film, etc., which could lead to data distortion. It reduces the time spent on manual pre-cleaning, thereby lowering testing costs. The squeegee assembly improves road surface cleanliness, the snap-fit structure facilitates quick assembly and disassembly of the waste collection box, and the detachable electromechanical box design facilitates maintenance, thus improving testing efficiency, data accuracy, and equipment usability.
