Description

Technical Field

[0001] This utility model relates to the technical field of road surface smoothness testing equipment, specifically a rapid road surface smoothness testing device based on laser scanning. Background Technology

[0002] Road surface smoothness is one of the important indicators for measuring road quality, which directly affects driving safety, comfort, and vehicle lifespan. Traditional road surface smoothness detection methods mainly rely on manual measurement or static detection equipment, which have problems such as low efficiency, poor accuracy, and high labor intensity. With the development of laser scanning technology, laser scanning-based road surface smoothness detection equipment has gradually become the mainstream. It has advantages such as fast detection speed, high accuracy, and high degree of automation. For example, CN206648616 U discloses a mobile road surface smoothness detection device, which emits a grid-shaped laser onto the road surface through a laser detection device. Then, the image acquisition device records the generated grid shape and sends it to the processor. The processor makes a data-based judgment on the road surface smoothness by analyzing and comparing the grid deformation. For example, the method and apparatus for detecting road surface smoothness disclosed in publication number CN 116356650 A provides methodological support for laser scanning of road surface smoothness and provides an apparatus. However, structurally speaking, the laser detection device (LiDAR) of the above-mentioned devices cannot be effectively stored when not in use, leaving it exposed and prone to damage, affecting the service life of the equipment. Furthermore, none of the above-mentioned devices can mark uneven areas on the road surface, resulting in poor performance. Utility Model Content

[0003] In view of the above-mentioned shortcomings in the existing technology, the purpose of this utility model is to provide a road surface smoothness rapid detection device that can improve the service life of the device and optimize the effect of the device.

[0004] The technical solution adopted by this utility model to achieve the above objectives is: a rapid road surface smoothness detection device based on laser scanning, including an outer casing, a laser scanner, a linear motion module, and a marking mechanism. The linear motion module is provided inside the outer casing. The linear motion module includes a linear motion platform. A mounting frame is fixedly connected to the linear motion platform. The laser scanner is fixedly connected to the mounting frame. A motion port is provided on the outer casing corresponding to the mounting frame. An outer sealing plate is fixedly connected to the end of the mounting frame. The marking mechanism is located on the bottom of the laser scanner on the outer casing of the device.

[0005] In the above technical solution, the marking mechanism includes a nozzle assembly and a pump. The equipment casing has a storage cavity inside. The pump is fixedly connected inside the equipment casing. The nozzle assembly is fixedly connected to the outer wall of the equipment casing. The pump is connected to the storage cavity through a first pipe. The pump is connected to the nozzle assembly through a second pipe.

[0006] In the above technical solution, the linear motion module further includes a first motor, a sliding column, and a lead screw. The sliding column is fixedly connected inside the outer casing of the equipment, and the linear motion table is slidably connected to the sliding column. The lead screw is threadedly connected to the linear motion table. The first motor is fixedly connected inside the outer casing of the equipment, and the first motor is poweredly connected to the lead screw.

[0007] In the above technical solution, the mounting frame includes a fixed frame, a rotating frame, and a second motor. The fixed frame is fixedly connected to the linear motion platform, the rotating frame is rotatably connected to the fixed frame, the laser scanner is fixedly connected to the rotating frame, the outer sealing plate is fixedly connected to the end of the rotating frame, and the second motor is fixedly connected to the fixed frame and is poweredly connected to the rotating frame.

[0008] In the above technical solution, the end of the fixed frame is provided with a rotating part, one end of the rotating frame is fixedly connected to a shaft, the shaft is rotatably connected to the rotating part, and the second motor is poweredly connected to the shaft.

[0009] In the above technical solution, an inner sealing plate is fixedly connected to one side of the laser scanner on the mounting bracket, and the second motor is fixedly connected to the inner sealing plate.

[0010] In the above technical solution, a liquid filling pipe is fixedly connected to the outer casing of the equipment and communicates with the storage cavity.

[0011] In the above technical solution, a mounting bracket is fixedly connected to the outer casing of the equipment.

[0012] The beneficial effects of this utility model are: 1. The linear motion module can drive the mounting frame to extend and retract, allowing the laser scanner to extend from inside the equipment casing to detect road surface flatness. When not in use, the laser scanner can be stored inside the equipment casing, and the movement port can be sealed by the outer enclosure plate. This effectively protects the laser scanner and prevents it from being exposed to the outside environment, which would affect the service life of the equipment. 2. The outer casing of the equipment is equipped with a marking mechanism. When the flatness of a certain section of road scanned by the laser scanner does not meet the requirements, the marking mechanism can mark the corresponding road to facilitate subsequent road repair, thereby optimizing the equipment's performance. 3. The mounting bracket includes a fixed bracket and a rotating bracket, and the laser scanner is fixedly connected to the rotating bracket. When the mounting bracket extends outward, the rotating bracket is driven to rotate through the second motor housing, thereby adjusting the scanning angle of the laser scanner and optimizing the scanning effect.

Detailed Implementation

[0015] 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.

[0016] Please see Figure 1-4 A rapid road surface smoothness detection device based on laser scanning includes an outer casing 100, a laser scanner 200, a linear motion module, and a marking mechanism. First, a linear motion module is provided inside the outer casing 100. The linear motion module includes a first motor 301, a sliding column 302, a lead screw 303, and a linear motion table 304. That is, a sliding column 302 is fixedly connected inside the outer casing 100, a linear motion table 304 is slidably connected to the sliding column 302, and a lead screw 303 is threadedly connected to the linear motion table 304. The first motor 301 is fixedly connected inside the outer casing 100 and is poweredly connected to the lead screw 303. When the first motor 301 drives the first lead screw 303 to rotate, the linear motion table 304 can perform linear motion on the sliding column 302. Secondly, a mounting frame 400 is fixedly connected to the linear motion table 304, and a laser scanner 200 is fixedly connected to the mounting frame 400. The laser scanner 200 is used to scan the ground, such as the laser detection device in a mobile road surface smoothness detection device disclosed in announcement number CN 206648616 U, or the lidar in the road surface smoothness detection method and device disclosed in announcement number CN 116356650 A. The specific detection method and system are existing technologies and will not be described in detail here. Furthermore, the outer casing 100 of the equipment has a movement port 305 corresponding to the mounting bracket 400, and an outer sealing plate 306 is fixedly connected to the end of the mounting bracket 400. In this way, when the linear motion table 304 moves linearly, it can drive the laser scanner 200 to pass through the movement port 305, thereby realizing road scanning. When not in use, the linear motion table 304 can drive the laser scanner 200 to move into the equipment outer casing 100 for storage and protection, and the outer sealing plate 306 seals the movement port 305 to prevent foreign objects from entering the interior. Through the above structure, the laser scanner 200 can be effectively protected, avoiding being exposed to the outside world and affecting the service life of the equipment. To further optimize, the aforementioned mounting frame 400 includes a fixed frame 401, a rotating frame 402, and a second motor 403. Specifically, the fixed frame 401 is fixedly connected to the linear motion table 304, and the rotating frame 402 is rotatably connected to the fixed frame 401. Specifically, the fixed frame 401 has a rotating part 404 at one end, and a shaft 405 is fixedly connected to one end of the rotating frame 402. The shaft 405 is rotatably connected to the rotating part 404. A laser scanner 200 is fixedly connected to the rotating frame 402, and an outer sealing plate 306 is fixedly connected to the end of the rotating frame 402. A second motor 403 is fixedly connected to the fixed frame 401. The second motor 403 is poweredly connected to the shaft 405. In this way, when the laser scanner 200 moves to the outside, the second motor 403 can drive the rotating frame 402 to rotate, thereby adjusting the scanning angle of the laser scanner 200 to improve the scanning effect. Furthermore, an inner sealing plate 406 is fixedly connected to one side of the laser scanner 200 on the mounting frame 400, and the second motor 403 is fixedly connected to the inner sealing plate 406. In this way, when the linear motion table 304 moves the laser scanner 200 to the outside, the inner sealing plate 406 can close the motion port 305, thereby preventing foreign objects from entering the interior through the motion port 305 during road surface flatness detection and improving the equipment's protective performance. Furthermore, a marking mechanism is provided on the bottom of the laser scanner 200 on the outer casing 100 of the equipment. This marking mechanism can mark areas with abnormal road surface smoothness for subsequent road repair. In this embodiment, the marking mechanism includes a nozzle assembly 501 and a pump 502. A storage cavity 102 is provided inside the outer casing 100, and the pump 502 is fixedly connected inside the outer casing 100. The nozzle assembly 501 is fixedly connected to the outer wall of the outer casing 100, with the nozzle assembly 501 facing the ground. The pump 502 is connected to the storage chamber 102 via a first pipe, and the pump 502 is connected to the nozzle assembly 501 via a second pipe 503. Thus, when marking is performed, the pump 502 can pump the marking liquid (which can be paint) stored in the storage chamber 102, and then the marking liquid is sprayed from the nozzle assembly 501 onto the ground to achieve marking. Of course, a liquid filling pipe 504 is fixedly connected to the outer casing 100 of the equipment and communicates with the storage chamber 102, through which marking liquid can be added to the storage chamber 102. Finally, a connecting frame 400 is fixedly connected to the outer casing 100 of the equipment. The equipment can be installed on a movable device, such as a trolley or a car, through the connecting frame 400. Furthermore, in this embodiment, the control of the first motor 301, the second motor 403, and the pump 502 can be any control method in the prior art, as long as the desired effect is achieved.
