Description

[0002] Security inspection is an indispensable technology in human production and life in today's society. Especially for industrial production, safety is one of the most important factors. Various methods need to be adopted in the industrial production process to ensure safe production. At present, many companies use manual inspections to conduct safety inspections, but manual inspections are not only labor-intensive but also inefficient. The technology of using robots for intelligent inspections is becoming increasingly popular, such as in power, rail transit and other application scenarios;

[0003] For example, in the utility model patent entitled "An inspection robot with shock absorption effect" and with publication number CN220261028U, a shock absorption effect is achieved by using the wheels, mounting shafts, transmission shafts and shock absorption mechanism in a transmission mechanism. The device has good shock absorption effect and inspection function, and is a better inspection robot than other traditional devices.

[0004] However, since the support of the fuselage by the rollers on both sides is in a balanced state when traveling on a horizontal road, the existing inspection robot has only one side of the roller that can move up and down. When the fuselage tilts, the other side of the roller moves up and down, its supporting force on the fuselage will increase or decrease, and the above balance will be broken. The fuselage will still tilt to one side to a certain extent, which is prone to rollover. Utility Model Content

[0024] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process. The specific work is as follows.

[0025] Embodiment 1: According to the attached drawings of the specification, when in use, the driving motor 6 starts the differential to rotate, and the differential drives the shaft rod 7 to rotate, which in turn causes the shaft rod 7 to drive the universal coupling to rotate, and the universal coupling drives the roller 8 to rotate, so that the inspection robot moves. When passing through a bumpy road section, the roller 8 is supported upward, and the roller 8 drives the concave frame 15 to rotate under the action of the connecting rod. At this time, the concave frame 15 pushes the piston rod 21 upward, and the piston rod 21 pushes the piston plate 20 upward to squeeze the shock-absorbing spring 19. The shock-absorbing spring 19 absorbs the pressure and deforms, thereby playing a shock-absorbing role. In this process, the damping oil 24 in the bearing cylinder 18 Through the oil hole 23, it moves from one side of the piston plate 20 to the other side. Since the damping oil 24 is relatively viscous, the piston plate 20 moves slowly, which not only absorbs the vibration, but also prevents the shock-absorbing spring 19 from rebounding quickly, thereby achieving a damping effect. When the height of the detector 4 needs to be adjusted, the first motor 10 is started, and the driving end of the first motor 10 drives the screw 11 to rotate. Since the lifting rod 14 and the screw 11 are meshed and connected by a threaded groove, when the screw 11 rotates, it has a driving effect on the lifting rod 14, and the lifting rod 14 drives the detector 4 to adjust the height. The detection direction of the detector 4 can be adjusted by the electric rotating table 3.

[0026] Embodiment 2: According to the attached drawings of the specification, when in use, the driving motor 6 starts the differential to rotate, and the differential drives the shaft rod 7 to rotate, which in turn makes the shaft rod 7 drive the universal coupling to rotate, and the universal coupling drives the roller 8 to rotate, so that the inspection robot moves. When passing through a bumpy section, the roller 8 is supported upward, and the roller 8 drives the concave frame 15 to rotate under the action of the connecting rod, and then the roller 8 is vibrated through the spring shock absorber 25. When the height of the detector 4 needs to be adjusted, the first motor 10 is started, and the driving end of the first motor 10 drives the screw 11 to rotate. Since the lifting rod 14 is meshed with the screw 11 through a threaded groove, when the screw 11 rotates, it has a driving effect on the lifting rod 14, and the lifting rod 14 drives the detector 4 to adjust the height. The detection direction of the detector 4 can be adjusted by the electric rotating table 3.
