Abstract
Description
Technical Field
[0001] This utility model belongs to the field of vehicle inspection technology, and more specifically, relates to an installation and adjustment device for laser scanning and inspection of the outer contour of a vehicle. Background Technology
[0002] With global economic development and the increasing number of cars on the road, the inspection and management of vehicles has become increasingly important. As a crucial basis for regulation, vehicle outline detection has become an essential component of intelligent transportation systems. The objects of vehicle outline detection include dimensions such as length, width, and height, as well as vehicle type classification. Vehicle outline detection technologies in the market are mainly classified into three categories: weighing technology, video technology, and laser technology. Among them, laser technology, with its high precision, strong anti-interference capabilities, and versatility, is gradually demonstrating its advantages and has become a focus of research for various manufacturers, providing managers with more options. Laser scanning-based vehicle outline detection systems have been widely applied in fixed overload control stations, highway entrance overload control stations, and off-site enforcement stations for detecting vehicles exceeding length, width, and height limits, as well as for preventing toll evasion.
[0003] As described in patent application CN201821315353.0, an installation and adjustment device for laser scanning detection of vehicle outlines includes a fixing rod, a connecting assembly, a protective cover, a laser scanning sensor, and an installation and adjustment device. The installation and adjustment device includes a rotating adjustment frame and two β adjustment frames. The rotating adjustment frame is used to adjust the orientation of the laser scanning sensor, and the two β adjustment frames are used to adjust the two swing directions of the laser scanning sensor, so that the scanning light curtain of the laser scanning sensor is parallel or perpendicular to the driving direction. The technical solution provided by this utility model can save costs, shorten installation time, and achieve higher installation and adjustment accuracy, realizing precise adjustment and fixation of the laser scanning sensor used for vehicle outline detection.
[0004] Although the aforementioned mounting and adjustment device for laser scanning detection of vehicle outer contours achieves precise adjustment and fixation of the laser scanning sensor used for vehicle outer contour detection, it does not take into account the issue of installation position adjustment, thereby reducing adjustment efficiency.

[0017] Specific Implementation Example 1: Please refer to... Figure 1-2 A mounting and adjustment device for laser scanning detection of vehicle outline includes a bracket 10; a slider 14 is slidably connected to the upper end of the bracket 10; a stepper motor 22 is embedded inside the slider 14, and the output end of the stepper motor 22 is fixedly connected to a gear 15; the slider 14 is rotatably connected to a gear 16; the gear 15 and gear 16 mesh; a mounting frame 17 is fixedly connected to the upper end of the gear 16; a mounting plate 23 is rotatably connected to the mounting frame 17; a stepper motor 19 is fixedly connected to the outer side of the upper end of the mounting frame 17; the output end of the stepper motor 19 is fixedly connected to the mounting plate 23; a stepper motor 11 is fixedly connected to the upper end of the bracket 10; a lead screw 13 is fixedly connected to the output end of the stepper motor 11; the lead screw... 13 is threadedly connected to slider 14; a pair of mounting bolts 21 are provided on the lower side of the mounting bracket 17; a rain shield 20 is provided on the outer side of the mounting bracket 17; the rain shield 20 and the mounting bracket 17 are detachably connected by a pair of mounting bolts 21; by setting stepper motor 11 and lead screw 13, the width of the large carriage of different sizes can be adapted to improve the adjustment efficiency; by setting stepper motor 29 and mounting plate 23, the convenience of the angle adjustment of scanner 18 is improved; by setting stepper motor 32, gear 15 and gear 26, the friction of gear 216 and gear 15 makes the angle adjustment of scanner 18 more stable, improves the stability of installation, and facilitates the subsequent rotation adjustment of scanner 18.
[0018] Please see Figure 2 A damping shaft is provided at the rotatable connection between the mounting plate 23 and the mounting bracket 17 to reduce the rotation amplitude of the mounting plate 23.
[0019] Please see Figure 1-2 The mounting plate 23 is bolted to the scanner 18; there is a gap between the mounting bracket 17 and the scanner 18.
[0020] Please see Figure 1 The rain shield 20 is made of stainless steel.
[0021] Please see Figure 1The upper end of the bracket 10 is fixedly connected to the slide plate 12; the slider 14 is slidably connected to the slide plate 12; by setting the rain shield 20, the scanner 18 is shielded by the rain shield 20. At the same time, since the rain shield 20 and the mounting bracket 17 are detachably connected by a pair of mounting bolts 21, the structure is simple and the installation is convenient, providing simple rain protection for the scanner 18.
[0022] During operation, the scanner 18 is placed on the mounting plate 23 and secured with bolts. Then, the output of stepper motor 11 rotates, causing the lead screw 13 to rotate. At this time, the slider 14 begins to move horizontally. When the slider 14 moves to the detection position, stepper motor 29 is activated. The output of stepper motor 29 drives the mounting plate 23 to rotate, causing the scanning angle of the scanner 18 to change and cover the height of the vehicle's outer contour. Stepper motor 32 is activated. The output of stepper motor 32 drives gear 15 to rotate, and gear 15 drives gear 26 to rotate, allowing the scanner 18 to completely scan the outer contour of the car.
[0023] When it is necessary to inspect the outer contour of a large car, the stepper motor 11 is started. The output end of the stepper motor 11 drives the lead screw 13 to rotate and connect. Since the lead screw 13 and the slider 14 are threadedly connected, the slider 14 can move to the other side of the bracket 10 to completely scan the outer contour of the car, which facilitates the installation and adjustment of the scanning equipment.
