[0002] At present, the highway inspection robot is an intelligent device specially designed for autonomous or remotely controlled inspection operations on highways.

[0003] High-speed inspection devices in the prior art generally tend to adopt a relatively large floor-standing design. This design certainly ensures the stability and comprehensiveness of the equipment to a certain extent, but it also brings a series of problems that cannot be ignored. First, the large floor-standing inspection device is huge in size, which makes it quite clumsy during transportation, installation and daily maintenance. This not only increases the difficulty of operation, but also invisibly increases the cost of manpower and material resources, and poses a considerable challenge to the flexibility and efficiency of the inspection work. Secondly, due to the limitation of size, such devices often seem to be unable to cope with narrow or complex terrain.

[0048] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] Example 1

[0050] like Figures 1 to 8As shown, a non-ground-type intelligent inspection robot for highway maintenance data collection includes a partition 101, a main body 10, a main moving mechanism 1, two batteries 102, two auxiliary moving mechanisms 2, a solar mechanism 3 and an inspection camera mechanism 4, the main body 10 is arranged on one side of the partition 101, the two batteries 102 are respectively fixedly connected to the two ends of the main body 10, the main moving mechanism 1 is installed in the middle of the main body 10, the two auxiliary moving mechanisms 2 are respectively installed at the two ends of the main body 10, the solar mechanism 3 is installed on the top of the main body 10, and the inspection camera mechanism 4 is installed inside the main body 10;

[0051] The main moving mechanism 1 includes a rotating motor 11 and a rotating shaft 12. The rotating motor 11 is installed inside the main body 10. The rotating shaft 12 is rotatably installed inside the main body 10. The rotating shaft 12 is connected to the output end of the rotating motor 11 through a coupling. A main wheel 13 is fixedly sleeved on the outer circumference of the rotating shaft 12. A friction pad 131 is provided on the outer circumference of the main wheel 13. Through the arrangement of the main moving mechanism 1, the auxiliary moving mechanism 2 and other structures, the main moving mechanism 1 and the auxiliary moving mechanism 2 work together to ensure the stability and accuracy of the equipment movement. At the same time, the inspection camera mechanism 4 can collect image data of the highway in real time, providing strong support for subsequent maintenance and management.

[0052] like Figure 1 to Figure 3 As shown, four symmetrically arranged reinforcing ribs 1011 are fixedly connected to the upper part of the main body 10, two symmetrically arranged connecting rods 1012 are fixedly connected to the middle part of the main body 10, a warning light 1013 is installed on the connecting rod 1012, a handle strap 1021 is fixedly connected to one side of the battery 102, and a charging port 1022 is installed on one side of the battery 102.

[0053] like Figure 1 to Figure 7 As shown, the auxiliary moving mechanism 2 includes a screw motor 21, a long rod 212 and a second sliding block 22. The screw motor 21 is installed inside the main body 10. The output end of the screw motor 21 is connected to a coaxially arranged transmission screw 211 through a coupling. The long rod 212 and the second sliding block 22 are both slidably assembled inside the main body 10. The long rod 212 is movably sleeved on the outer circumference of the transmission screw 211. One side of the long rod 212 is fixedly connected to a first curved rod 213. The first curved rod 213 is slidably assembled inside with a first sliding rod 214. One side of the first sliding rod 214 is fixedly connected to a first sliding block 215. The first sliding block 215 is rotatably mounted with an auxiliary outer wheel 216.

[0054] One side of the second sliding block 22 is fixedly connected with three symmetrically arranged second curved rods 221, inside of which the first auxiliary inner wheel 222 and two symmetrically arranged second auxiliary inner wheels 223 are rotatably installed respectively, and one side of the second sliding block 22 is fixedly connected with three symmetrically arranged second sliding rods 224.

[0055] like Figure 1 to Figure 6 As shown, a first spring 2141 is provided inside the first sliding rod 214, and first dampers 2142 are installed at both ends of the first spring 2141, one of the first dampers 2142 is installed on one side of the main body 10, and the other first damper 2142 is installed on one side of the first sliding block 215, and a second spring 2241 is provided inside the second sliding rod 224, and second dampers 2242 are installed at both ends of the second spring 2241, one of the second dampers 2242 is installed on one side of the main body 10, and the other second damper 2242 is installed on one side of the second sliding block 22.

[0056] like Figure 1 to Figure 3 As shown, the inspection camera mechanism 4 includes two straight rods 41 , both of which are fixedly connected to the inside of the main body 10 , and an inspection camera 42 is installed at the bottom of the straight rods 41 .

[0057] In this embodiment, before the device needs to be used, the battery 102 is first charged through the charging port 1022 on the battery 102. After charging is completed, the main body 10 is lifted up by the two handle straps 1021. After lifting, the main wheel 13 and the first auxiliary inner wheel 222 and the two second auxiliary inner wheels 223 on the main body 10 are attached to the partition 101, and then the screw motor 21 on the secondary moving mechanism 2 is turned on. The rotation of the screw motor 21 causes the transmission screw 211 to rotate, and the transmission screw 211 rotates. The long rod 212 is rotated to move toward the partition 101. When the long rod 212 moves, the auxiliary outer wheel 216 is fitted with the other side of the partition 101. After the fitting is completed, the main moving mechanism 1 is turned on. The main moving mechanism 1 is turned on to start the rotating motor 11. The starting of the rotating motor 11 causes the rotating shaft 12 to rotate. The rotation of the rotating shaft 12 causes the main wheel 13 to rotate. During the rotation process, the main wheel 13 causes the friction pad 131 to rub against the partition 101, thereby increasing its service life. During the movement of the main wheel 13, the auxiliary outer wheel 216, the first auxiliary inner wheel 222 and the second auxiliary inner wheel 223 assist the movement of the main body 10. When the partition 101 is slightly deformed or there is a foreign object, the positions of the auxiliary outer wheel 216, the first auxiliary inner wheel 222 and the second auxiliary inner wheel 223 are adjusted by the first spring 2141 inside the first sliding rod 214 and the second spring 2241 inside the second sliding rod 224. During the adjustment of the auxiliary outer wheel 216, the first auxiliary inner wheel 222 and the second auxiliary inner wheel 223, the first damper 2142 and the second damper 2242 are combined to effectively prevent the first spring 2141 and the second spring 2241 from sliding by themselves due to their spring characteristics, thereby improving the stability and applicability of the equipment movement. During the movement of the main body 10, the inspection camera 42 on the inspection camera mechanism 4 is used to shoot real-time highway image data, including road conditions, traffic signs, facilities and equipment, for real-time inspection and data collection.

[0058] Example 2

[0059] like Figures 1 to 8As shown, the solar mechanism 3 includes two top rods 31, a servo motor 32 and a solar panel 37. The two top rods 31 are fixedly connected to the top of the main body 10. The tops of the two top rods 31 are movably hinged with a first hinge rod 311. The servo motor 32 is installed on the top of the main body 10. The output end of the servo motor 32 is connected to a coaxially arranged transmission shaft 33 through a coupling. A second hinge rod 34 is fixedly connected to the outer circumference of the transmission shaft 33. A third hinge rod 35 is movably hinged on the second hinge rod 34. The third hinge rod 35 is rotatably installed with a hinge shaft 311 inside. 6. The solar panel 37 is installed on the top of the hinge shaft 36 and the two first hinge rods 311. A photosensitive sensor 371 is installed on one side of the solar panel 37. Through the arrangement of the warning light 1013, the solar mechanism 3 and other structures, during the use of the equipment, the turning on of the warning light 1013 effectively warns the moving vehicle and improves safety. The solar mechanism 3 automatically adjusts the angle of the solar panel 37 through the photosensitive sensor 371 to maximize the solar energy collection efficiency and realize auxiliary charging. This design not only saves the battery 102 power, but also improves the self-sufficiency of the equipment.

[0060] In this embodiment, during the use of the device, the warning light 1013 is turned on. The turning on of the warning light 1013 can effectively warn vehicles traveling on the highway. The solar mechanism 3 is used to assist in charging the battery 102. A photosensitive sensor 371 is provided on the solar panel 37 inside the solar mechanism 3. The angle of the solar panel 37 is automatically adjusted according to the feedback of the photosensitive sensor 371. The adjustment of the solar panel 37 is to turn on the servo motor 32. The rotation of the servo motor 32 causes the transmission shaft 33 to rotate. The rotation of the transmission shaft 33 causes the second articulated rod 34 to rotate. The rotation of the second articulated rod 34 causes the third articulated rod 35 and the articulated shaft 36 to be displaced. At this time, the first articulated rod 311 also follows the auxiliary displacement to maximize the efficiency of solar energy collection. When there is sufficient light, the robot can use solar energy for power supply to save the battery 102 power.
