Description

Technical Field

[0001] This utility model relates to the field of freight loading inspection technology, specifically to an intelligent loading dual-radar laser scanning device. Background Technology

[0002] LiDAR (Lidar) is a radar system that uses laser beams to detect the position, velocity, and other characteristics of targets. Currently, lidar scanning technology is applied in the field of freight vehicle loading inspection. Specifically, lidar can continuously scan the loading area of ​​trucks, collecting information such as the length, width, and height of the truck bed. The radar output data is then processed by a processor to output the processed vehicle outline information and real-time position information, as well as point cloud image data of the loaded material surface, providing auxiliary decision-making for loading tasks.

[0003] For example, CN 216189442 U discloses a lidar detection system for automatic loading of coal mine trains, which includes a mounting plate and a control box. The control box is fixedly connected to the bottom of one end of the mounting plate. The mounting plate has a sliding opening, and a screw is rotatably connected inside the sliding opening. A slider is threaded onto the screw, and a laser emitter is rotatably connected to the bottom of the slider via a rotating shaft. The laser emitter is connected to the top of the slider via a turnbuckle, and both ends of the turnbuckle are rotatably connected to the slider and the laser emitter, respectively. One end of the screw passes through the inner wall of the sliding opening and is fixedly connected to a knob. The outer wall of the mounting plate has a groove, and a guide rod is fixedly connected inside the groove. An L-shaped locking rod is slidably sleeved on the guide rod. This lidar detection system aims to quickly detect the loading status of coal mine trains, thereby improving the transportation efficiency of coal mines. However, the following problems still exist: the beam exit or entrance of the laser emitter and laser receiver are in a harsh working environment for a long time and are easily blocked by coal dust and other dust, affecting the detection accuracy. Utility Model Content

[0004] The purpose of this invention is to provide a smart vehicle-mounted dual-radar laser scanning device with a reasonable structure and reliable operation that solves the above problems and can ensure detection accuracy even in harsh working environments.

[0005] The technical solution of this utility model is:

[0006] A smart vehicle-mounted dual-radar laser scanning device includes a horizontal top frame and radar laser scanning components mounted on the horizontal top frame. The key technical features are: two radar laser scanning components, one arranged on the X-axis side of the horizontal top frame and the other on the Y-axis side; a protective cylinder corresponding to each radar laser scanning component is fixed to the lower surface of the horizontal top frame; a lifting cylinder corresponding to each protective cylinder is inverted on the upper surface of the horizontal top frame; a connecting column is provided at the lower end of the cylinder rod of each lifting cylinder; the lower end of the connecting column is connected and fixed to the top surface of the outer shell of each radar laser scanning component; a cover plate is fixed to the bottom surface of the outer shell of each radar laser scanning component; a limiting stop corresponding to the cover plate is provided at the lower end of each protective cylinder; an air inlet is provided on the side wall of each protective cylinder; an air pump is provided on the horizontal top frame; a filter layer is provided at the inlet of the air pump; and the outlet of the air pump is connected to the air inlets on the two protective cylinders via a pipeline.

[0007] The aforementioned intelligent vehicle loading dual radar laser scanning device has two guide rods symmetrically arranged on the side wall of the connecting column, and the inner wall of the protective cylinder has longitudinal guide grooves corresponding to the ends of the guide rods.

[0008] The aforementioned intelligent vehicle loading dual-radar laser scanning device has multiple mounting rods on the upper surface of the horizontal top frame.

[0009] In the aforementioned intelligent vehicle-mounted dual radar laser scanning device, the upper stop point of the detection port of the radar laser scanning component faces the air inlet of the protective cylinder.

[0010] The beneficial effects of this utility model are:

[0011] 1. In use, two radar laser scanning components arranged at right angles are used to detect freight vehicles and loading surfaces, further improving detection accuracy.

[0012] 2. During testing, the two radar laser scanning components move downwards under the action of their respective lifting cylinders to perform the testing operation. After the testing is completed, in order to avoid dust causing a decrease in the detection accuracy of the radar laser scanning components, the lifting cylinders drive the radar laser scanning components to rise and drive the cover plate to be fastened to the lower end of the corresponding protective cylinder. Even in harsh working environments, the detection accuracy of the radar laser scanning components can be guaranteed.

[0013] 3. During the testing process, dust may be adsorbed at the detection port of the radar laser scanning component. Before closing the cover, start the air pump to filter the outside air and send it into the protective cylinder, blowing off the dust at the detection port and then blowing it out of the protective cylinder, thereby achieving the cleaning purpose and ensuring the accuracy of the next test.

[0017] The present invention will be described in detail with reference to the accompanying drawings.

[0018] like Figure 1 , Figure 2 As shown, the intelligent vehicle-mounted dual-radar laser scanning device includes a horizontal top frame 2 and a radar laser scanning assembly 9 mounted on the horizontal top frame 2. The upper surface of the horizontal top frame 2 is provided with multiple mounting rods 1.

[0019] The radar laser scanning component 9 consists of two parts, one of which is arranged on the X-direction side of the horizontal top frame 2 and the other is arranged on the Y-direction side of the horizontal top frame 2.

[0020] The lower surface of the horizontal top frame 2 is fixed with a protective cylinder 7 corresponding to the radar laser scanning component 9. The upper surface of the horizontal top frame 2 is inverted with a lifting cylinder 3 corresponding to the protective cylinder 7. The lower end of the cylinder rod of the lifting cylinder 3 is provided with a connecting column 11. The lower end of the connecting column 11 is connected and fixed to the top surface of the outer shell of the radar laser scanning component 9. The bottom surface of the outer shell of the radar laser scanning component 9 is fixed with a cover plate 8. The lower end of the protective cylinder 7 is provided with a limiting stop corresponding to the cover plate 8. In this embodiment, two guide rods 12 are symmetrically provided on the side wall of the connecting column 11, and the inner wall of the protective cylinder 7 is provided with a longitudinal guide groove 13 corresponding to the end of the guide rod 12.

[0021] The protective cylinder 7 has an air inlet 10 on its side wall, and an air pump 5 is mounted on the horizontal top frame 2. The air pump 5 has a filter layer 4 at its inlet, and its outlet is connected to the air inlets 10 on the two protective cylinders 7 via a pipe 6. The upper stop point of the detection port 901 of the radar laser scanning assembly 9 faces the air inlet 10 of the protective cylinder 7.

[0022] Working principle:

[0023] When the loading vehicle arrives at the loading position, the two radar laser scanning components 9 (the transmitter and receiver of each radar laser scanning component 9 are located on the same side and are concentrated at the detection port 901) move down under the action of the corresponding lifting cylinder 3 and reach the outside of the protective cylinder 7 to realize bidirectional scanning and information acquisition.

[0024] After the scanning operation is completed, the lifting cylinder 3 drives the radar laser scanning component 9 to rise. At the same time, the air pump 5 is started to filter the outside air and send it into the protective cylinder 7, and blow off the dust at the detection port 901 and blow it out of the protective cylinder 7. Finally, the cover plate 8 is fastened to the lower end of the protective cylinder 7.

[0025] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made within the scope of this utility model should still fall within the scope of this patent.
