[0034] according to Figure 2 、 Figure 3 and Figure 6 As shown, the inner wall of the battery box 219 is provided with a plurality of heat dissipation holes 225 at equal intervals. Two fixing frames 226 are installed inside the battery box 219, and the bottoms of the two fixing frames 226 are in contact with the top of the battery body 220. A battery cover 227 is installed on the top of the battery box 219. The outer surfaces of the two electric push rods 203 are provided with stabilizing frames 228. The two stabilizing frames 228 are both installed on the top of the crawler 1 by bolts, so that the entire maintenance robot can be driven to move under the action of the crawler 1.

[0035] according to Figure 1 、 Figure 2 and Figure 7 As shown, a stabilizing mechanism 3 is provided on the top of the crawler 1. The stabilizing mechanism 3 includes two second electric telescopic rods 301, two mounting grooves 302 and four rectangular holes 303. The two second electric telescopic rods 301 are respectively installed at the bottom of the inner wall of the two mounting grooves 302. The two mounting grooves 302 are both opened at the top of the crawler 1. Each rectangular hole 303 is opened at the top of the crawler 1. A concave column 307 is movably connected to the inside of each rectangular hole 303, which is convenient for ensuring that the porous column 309 can move vertically under the action of the concave column 307.

[0036] according to Figure 2 and Figure 7As shown, the four concave columns 307 are divided into two groups, and a rectangular plate 304 is fixed between the opposite sides of each group of concave columns 307. The bottoms of the two rectangular plates 304 are respectively installed with the top ends of the telescopic ends of the two second electric telescopic rods 301 through first screws. A card slot 305 is opened on the opposite side of each group of concave columns 307, and a support plate 306 is provided inside each card slot 305. The four support plates 306 are divided into two groups, and each group of support plates 306 is respectively installed on the bottom of each rectangular plate 304 through second screws. A rectangular block 308 is fixed between the opposite sides of each group of concave columns 307, which is convenient for the concave column 307 to move stably vertically with the cooperation of the rectangular block 308, the rectangular hole 303 and the rectangular plate 304.

[0037] according to Figure 2 and Figure 7 As shown, a porous column 309 is provided inside each concave column 307, and an anti-slip pad 310 is bonded to the top of each porous column 309. A fixing bolt 311 is movably passed through the same surface of each group of concave columns 307, and one end of each fixing bolt 311 is movably passed through the inside of one of the through holes on each porous column 309. One end of each fixing bolt 311 is threaded through the inner wall of each concave column 307, so that the moved porous column 309 can be fixed with the cooperation of the fixing bolt 311 and the concave column 307.

[0038] The effect achieved by the entire mechanism is: when it is necessary to conduct regular inspections on the oil pipeline, the controller 201 is directly connected to the ground control console through the wireless transmission module 216, and the crawler 1 is also connected to the ground control console. At the same time, an appropriate amount of corrosion inhibitor liquid is placed inside the liquid storage shell 222. When everything is ready, the entire maintenance robot is moved to the inlet of the oil pipeline, and according to the height of the steel wire plate 210, all the fixing bolts 311 are taken out from the inside of the corresponding concave column 307 in turn, and then the height of each porous column 309 is adjusted in turn until the top of each porous column 309 is on the same horizontal plane as the top of the steel wire plate 210, and then the fixing bolts 311 and the matching through holes on the porous column 309 are used. The porous column 309 can be fixed inside the corresponding concave column 307, and then the ground control console can be used to directly control the crawler 1 to move inside the oil pipeline. When the crawler 1 moves, the moving crawler 1 will drive the maintenance mechanism 2 and the stabilization mechanism 3 to move. At the same time, the panoramic camera 218 will always transmit the captured images in the form of electrical signals, and at the same time, through the cooperation of the controller 201 and the wireless transmission module 216, it will be directly transmitted to the display screen of the ground control console for staff to observe. When the staff observes that the inner wall of the oil pipeline is corroded through the display screen on the ground control console, the staff can directly move the steel plate 210 to the oil pipeline through the cooperation of the panoramic camera 218 and the crawler 1. When the steel plate 210 moves to the position of the corrosion on the inner wall of the oil pipeline, the staff will directly use the cooperation of the ground control console, the controller 201 and the wireless transmission module 216 to synchronously start the two electric push rods 203. At this time, the two started electric push rods 203 will directly drive the mounting plate 204 connected thereto to move vertically upward with the cooperation of the corresponding stabilizing frame 228, and the upwardly moving mounting plate 204 will drive the steel plate 210 to move upward through the cooperation of the rotating block 208. When the top of the steel plate 210 contacts the position of the corrosion on the inner wall of the oil pipeline, the two electric push rods 203 will be directly paused at this time. Then, the cooperation of the ground control console, the controller 201 and the wireless transmission module 216 will be used to control the two second electric push rods 203 to move upward. The retracting rods 301 are activated at the same time. At this time, the two second electric telescopic rods 301 activated will directly drive the corresponding concave columns 307 to move vertically upward under the cooperation of the corresponding mounting slots 302, rectangular plates 304, card slots 305, support plates 306, rectangular blocks 308 and rectangular holes 303. At this time, each moving concave column 307 will drive the corresponding porous column 309 to move under the cooperation of the corresponding fixing bolts 311, and the moving porous column 309 will also drive the corresponding anti-slip pad 310 to move. When the tops of the four anti-slip pads 310 are in contact with the inner wall of the oil pipeline, the two second electric telescopic rods 301 are directly suspended. Then, with the cooperation of the ground control console, controller 201 and wireless transmission module 216,The motor 207 is started to rotate forward and reverse. At this time, the started motor 207 will directly drive the rotating block 208 to rotate left and right with the cooperation of the rotating rod 206 and the limiting hole 205. At this time, the rotating rotating block 208 will drive the wire plate 210 to rotate left and right. At this time, the rotating wire plate 210 can stably grind and remove rust on the corroded position on the inner wall of the oil pipeline. When the panoramic camera 218 observes that the corroded position on the inner wall of the oil pipeline is almost polished, the two electric push rods 203 are started synchronously. Through the cooperation of the mounting plate 204 and the rotating block 208, the top of the wire plate 210 is separated from the inner wall of the oil pipeline. When the top of the wire plate 210 just separates from the inner wall of the oil pipeline, the two electric push rods 203 are paused again. At this time, the cooperation of the ground control console, the controller 201 and the wireless transmission module 216 is used to directly start the first electric telescopic rod 212 and the water pump 221. At this time, the telescopic end of the first electric telescopic rod 212 is between the hollow block 213 and the round tube 214. With the cooperation of the rotating block 208, the nozzle 215 is directly moved out from the lower side of the rotating block 208. At this time, the nozzle of the nozzle 215 is rotated left and right to aim at the corroded position of the inner wall of the oil pipeline that has been polished. Then, the water pump 221 is started and, with the cooperation of the liquid inlet pipe 223, the hose 224 and the round pipe 214, the corrosion inhibitor liquid is directly sucked out from the inside of the liquid storage shell 222 and sprayed on the inner wall of the oil pipeline that has just been polished and derusted. When the corrosion inhibitor is sprayed on the stone When the inner wall of the oil pipeline has been polished and rust-removed, a layer of anti-corrosion film is directly formed there. When the maintenance robot completes the maintenance operation, it directly controls the water pump 221 to shut down, then uses the first electric telescopic rod 212 to drive the nozzle 215 to reset, then controls the motor 207 to shut down, and then uses the two second electric telescopic rods 301 and the concave column 307 to cooperate to reset all the anti-slip pads 310. Finally, the maintenance robot is controlled to move again to continue inspecting the inner wall of the oil pipeline.

[0039] Among them, the crawler 1 is mainly composed of a walking mechanism, a power supply, a control mechanism and a communication device. The simple principle is that the ground control console controls the direction of the walking mechanism, whether to walk and other operations through the cooperation of the communication device and the control mechanism.

[0040] Among them, the crawler 1, controller 201, electric push rod 203, motor 207, first electric telescopic rod 212, wireless transmission module 216, panoramic camera 218, battery body 220, water pump 221 and second electric telescopic rod 301 are all existing technologies and will not be explained in detail here.

[0041] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
