DETAILED DESCRIPTION

[0021] 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.

[0022] like Figure 2~Figure 7 As shown, this embodiment proposes a detection device for surveying underground disease bodies of roads, and its structure includes a body 1. The data acquisition device in this embodiment is arranged at the lower end of the body 1, and is used to collect disease body data. The first moving structure, the second moving structure and the steering structure are arranged on the body 1. Among them, the first moving structure is used to make the body 1 move on a smooth road surface; the second moving structure is used to make the body 1 move on a bumpy road surface; the steering structure is used to make the body 1 turn, the signal receiver 16 is arranged on the body 1, and the signal receiver 16 is connected to the first moving structure, the second moving structure and the steering structure. The camera 17 is fixedly arranged on the body 1, and the signal transmitter is connected to the signal receiver 16. This embodiment collects specific information of the area to be detected through the camera 17, and the operator does not need to be present in person to remotely understand the information of the detection area. In this embodiment, a searchlight can be added in front of the camera 17 to facilitate operation in a dimly lit environment.

[0023] The steering structure in this embodiment includes a first control motor 451, and the machine body 1 includes a first frame 11 and a second frame 12. The first control motor 451 is fixedly connected to the machine body 1, and the first mounting plate 43 and the second mounting plate 44 are fixedly arranged on the first frame 11. The first screw rod 45 and the first sliding rod 46 are rotatably arranged on the first mounting plate 43 and the second mounting plate 44. The first sliding rod 46 is adopted in this embodiment so that the sliding rack 41 will not produce movement deviation when the sliding rack 41 moves. The output shaft of the first control motor 451 is fixedly connected to the first screw rod 45, the first screw rod 45 and the first sliding rod 46 are parallel to each other, the steering gear 42 is fixedly arranged on the second frame 12, the sliding rack 41 is meshed with the steering gear 42, the sliding rack 41 is threadedly connected to the first screw rod 45, and the sliding rack 41 is slidingly connected to the first sliding rod 46. The first control motor 451 adopted in this embodiment is a two-phase motor. Since the rotation stroke of the screw rod is much larger than the rotation stroke of the second frame 12 relative to the first frame 11, the rotation angle of the second frame 12 controlled by the first screw rod 45 is more accurately controllable, which facilitates the operator to remotely control the movement of the machine body 1.

[0024] The first moving structure in this embodiment includes a first moving wheel 21, a second moving wheel 22, a third moving wheel 23 and a fourth moving wheel 24, a first rotating shaft 211 is fixedly disposed between the first moving wheel 21 and the second moving wheel 22, the first rotating shaft 211 is rotatably connected to the first frame 11, a second rotating shaft 212 is fixedly disposed between the second moving wheel 22 and the third moving wheel 23, and the second rotating shaft 212 is rotatably connected to the second frame 12. In this embodiment, the first moving wheel 21, the second moving wheel 22, the third moving wheel 23 and the fourth moving wheel 24 are used to control the movement of the machine body 1 on a smooth road surface, thereby ensuring that the machine body 1 is more stable during the movement process, the machine body 1 will not jump, and the movement efficiency of the machine body 1 is improved.

[0025] The second moving structure in this embodiment includes a first moving member 51, a second moving member 52, a third moving member 53 and a fourth moving member 54. The first moving member 51 and the second moving member 52 are rotatably arranged on both sides of the first rotating shaft 211, and the third moving member 53 and the fourth moving member 54 are rotatably arranged on both sides of the second rotating shaft 212. The first moving member 51 includes a first rotating sleeve 61, and the first moving rod 511, the second moving rod 512 and the third moving rod 513 are fixedly arranged on the first rotating sleeve 61. In this embodiment, the first rotating sleeve 61 is sleeved on the first rotating shaft 211. The first moving rod 511, the second moving rod 512 and the third moving rod 513 are 120° apart from each other, and the lengths of the first moving rod 511, the second moving rod 512 and the third moving rod 513 are all greater than the radius of the first moving wheel 21. Such a design ensures that when encountering a pothole section, the moving wheel on the machine body 1 sinks into the depression. At this time, by rotating the first rotating sleeve 61, the moving member replaces the moving wheel to contact the road surface, and the wheel is taken away from the depression. When the machine body 1 is traveling on a smooth road, it is only necessary to rotate the moving part away from the road surface. At this time, the moving wheel contacts the road surface instead of the moving part, so that the machine body 1 can move forward smoothly and efficiently on the smooth road surface.

[0026] In this embodiment, the ends of the first moving rod 511, the second moving rod 512 and the third moving rod 513 are all fixed with a moving disk 5111, and a buffer layer 5112 is fixedly arranged on the periphery of the moving disk 5111. The buffer layer 5112 is made of rubber material to reduce the collision damage caused by the long-term contact between the moving disk 5111 and the road surface, thereby improving the service life of the equipment. The first moving member 51, the second moving member 52, the third moving member 53 and the fourth moving member 54 have the same structure. The cylindrical structure of the moving disk 5111 ensures that when encountering a complex road surface, the periphery of the moving disk 5111 has a foothold in contact with the road surface, so that the body 1 can be propped up and moved on a bumpy road surface.

[0027] In the present embodiment, a second control motor 821 is provided in the first frame 11, and a first adjustment structure is arranged between the second control motor 821 and the first rotating shaft 211, and is used to adjust the speed of the first rotating shaft 211. The first adjustment structure includes a first speed regulating member 81, which is fixedly connected to the first rotating shaft 211. The second speed regulating member 82 is rotatably arranged on the first frame 11, and the first speed regulating member 81 and the second speed regulating member 82 are both truncated cone-shaped structures, and the conveyor belt 811 is connected and arranged between the first speed regulating member 81 and the second speed regulating member 82. The first speed regulating member 81 and the second speed regulating member 82 are of the same size, and the first speed regulating member 81 and the second speed regulating member 82 are symmetrically placed to ensure that the conveyor belt 811 will not be separated from the first speed regulating member 81 and the second speed regulating member 82 during the movement, thereby causing the movement to deviate. The conveyor belt 811 used in the present embodiment is made of rigid and hard materials (such as metal, plastic, etc.). It is ensured that the conveyor belt 811 will not be skewed or deviated during the movement. Since the transmission ratio between the first speed regulating member 81 and the second speed regulating member 82 changes during the movement of the conveyor belt 811 , the movement speed of the machine body 1 can be adjusted.

[0028] The third control motor 911 in this embodiment is fixedly arranged on the first frame 11, the third mounting plate 14 and the fourth mounting plate 15 are fixedly arranged on the first frame 11, the second screw rod 92 and the second sliding rod 91 are rotatably arranged between the third mounting plate 14 and the fourth mounting plate 15, the adjusting member 812 is arranged between the first speed regulating member 81 and the second speed regulating member 82, both ends of the adjusting member 812 are slidably connected to the conveyor belt 811, and the adjusting member 812 is threadedly connected to the second screw rod 92. The adjusting member 812 is slidably connected to the second sliding rod 91 to prevent the adjusting member 812 from moving out of position. The output shaft of the third control motor 911 is fixedly connected to the second screw rod 92. Since the movement stroke of the screw rod is much larger than the movement stroke of the adjusting member 812, the movement speed of the control body 1 can be controlled to reach the target value more accurately.

[0029] In this embodiment, the connecting member 83 is fixedly arranged on the first rotating sleeve 61, and the connecting member 83 is a truncated cone structure, and the connecting member 83 and the first speed regulating member 81 are combined into a truncated cone structure. Such a design ensures that when the conveyor belt 811 moves to contact the connecting member 83, the transmission ratio increases, the rotation speed of the moving member decreases, and it is easier to pass through the pothole section.

[0030] In this embodiment, the second rotating sleeve 62 is fixedly arranged on the second moving member 52, the first rotating gear 71 is fixedly arranged on the first rotating sleeve 61, the second rotating gear 72 is fixedly arranged on the second rotating sleeve 62, the third rotating gear 73 and the fourth rotating gear 74 are rotatably arranged on the first frame 11, the connecting shaft 731 is fixedly arranged between the third rotating gear 73 and the fourth rotating gear 74, the third rotating gear 73 is meshed with the first rotating gear 71, the fourth rotating gear 74 is meshed with the second rotating gear 72, and the structure of the second frame 12 is the same as that of the first frame 11, which is used to ensure that the machine body 1 is a four-wheel drive, so that the machine body 1 can cope with various complex road surfaces. Such a design ensures that when the conveyor belt 811 controls the rotation of the first moving member 51, the meshing of the rotating gears can synchronously drive the second moving member 52 to rotate, ensuring that the machine body 1 moves more smoothly and reliably on pothole sections.

[0031] In this embodiment, the lower end of the first frame 11 is also provided with an installation box 3, and the data acquisition device is fixedly arranged in the installation box 3. A telescopic member 31 is provided between the first frame 11 and the installation box 3, and the fixed end of the telescopic member 31 is fixedly connected to the first frame 11, and the telescopic end of the telescopic member 31 is fixedly connected to the installation box 3. A sliding rail 13 is also provided at the lower end of the first frame 11, and the installation box 3 is slidingly connected to the sliding rail 13. The telescopic member 31 used in this embodiment is preferably a hydraulic cylinder or a cylinder. Among them, the hydraulic cylinder or the cylinder is the prior art, and this embodiment will not be repeated. When the body 1 is moving on a flat road, the telescopic member 31 extends to drive the data acquisition device close to the road surface, thereby improving the accuracy of the data collected by the data acquisition device; and when the body 1 moves on a bumpy road surface, the telescopic member 31 contracts to drive the data acquisition device away from the road surface, thereby preventing the bumpy road section from colliding with the data acquisition device on the road surface.

[0032] The working process of this embodiment is as follows: when the detection equipment is working on a flat road, the telescopic member 31 is extended to make the data acquisition device close to the road surface, and the operator observes the road condition through the camera 17, and then conveys the movement and steering instructions to the signal receiver 16 according to the road condition. The body 1 receives the instructions, controls the steering by controlling the first control motor 451, and controls the movement of the body 1 by controlling the second control motor 821, so as to realize the detection of the specified position; when the detection equipment is working on a bumpy road surface, the telescopic member 31 is retracted to make the data acquisition device away from the road surface, and the conveyor belt 811 is contacted with the connecting member 83 by starting the third control motor 911. At this time, the second control motor 821 is started to drive the first moving member 51, the second moving member 52, the third moving member 53 and the fourth moving member 54 to rotate, so that the body 1 is separated from the bumpy road surface.

[0033] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
