When a loose screw is found, the manipulator 101 drives the device body 1 to move closer to the position of the loose screw. During the movement, the second camera 201 accurately locates the screw that needs to be tightened. Then the first electric telescopic rod 203 drives the electric extension and tightens the screw through the electric sleeve 202.

The output end of the battery 104 is connected to the input end of the device body 1 and the input end of the manipulator 101 to provide them with power. When the battery 104 is less than 10% in power, it will automatically return to prevent the device body 1 from falling from a height.

[0020] In this embodiment, the device body 1 is connected to a wireless terminal, which is an electronic product such as a computer or a mobile phone. The device body 1 can be operated on the mobile terminal.

The device of the utility model can provide power for the device through a built-in battery, which can be implemented by technicians in the relevant technical field and will not be described in detail here.

[0025] The utility model is implemented in detail as follows: when in use, the robot is manipulated at the mobile terminal, and the robot will conduct inspections in the designated area. At this time, the mechanical mobile terminal 102 climbs upwards through the principle of magnetic attraction. During the climbing process, the first camera 103 continuously scans the looseness and corrosion of the screws. When a loose screw is found, the manipulator 101 drives the device body 1 to approach the position of the loose screw. During the movement, the second camera 201 accurately locates the screw that needs to be tightened, and then the first electric telescopic rod 203 drives the electric extension and tightens the screw through the electric sleeve 202. When the distance between the nut and the stud is small, it proves that the screw is tightened. Then the first electric telescopic rod 203 drives the electric sleeve 202 to shorten the process of tightening the screw. When the first camera 103 finds corrosion, the manipulator 10 1 drives the mobile terminal to move to the corrosion position, and then the second electric telescopic rod 302 drives the marking pen 301 to extend and mark. When the marking pen 301 contacts the steel structure, the device body 1 will move forward one step to leave a mark, and then the second electric telescopic rod 302 will shorten to complete the marking process. During the process of tightening the screws and marking, the first camera 103 and the second camera 201 will take pictures and send them to the mobile terminal. During the process of tightening the screws, the first camera 103 and the second camera 201 judge the tightness of the screws by the distance from the nut to the stud, so there is a certain error. During the marking process, the first camera 103 judges the corrosion situation by the color difference of the steel structure pattern and the like, and the first camera 103 can only judge the approximate position. Therefore, when dealing with rust, workers need to check the corrosion situation around the mark.
