[0029] The bending part includes a bending electric cylinder 22 provided inside the swivel ring 17.

The cleaning part includes a cleaning control electric cylinder 19 provided inside the swivel ring 17. A cleaning part 20 is provided on the telescopic rod of the cleaning control electric cylinder 19.

[0030] The working principle is as follows: When in use, the operator can move and set the detection assembly in a preset area of the cab for mobile positioning. For pipeline 1 and pipeline 2, they can move within the detection assembly. The two ends of the oil pipe are respectively docked with the oil cylinder assembly 4 and the oil changer assembly 1. Specifically, in this embodiment, the high-pressure oil pipe is composed of pipeline 1, pipeline 2, and the detection assembly. The detection assembly can move on pipeline 1 and pipeline 2 to perform real-time monitoring on pipeline 1 and pipeline 2. When connecting, the docking seal part 28 is respectively in sealed docking with the oil cylinder port 5 and the docking port of the oil changer assembly 1. The mating shaft 29 is in cooperation with the mating hole on the docking plate 501, and the buckle plate 30 is simultaneously buckled with the buckle seat 6 to achieve fixation, that is, the ends of pipeline 1 and pipeline 2 are fixed on the oil cylinder port 5 and the docking port of the oil changer assembly 1. When buckling, the buckle plate 30 moves telescopically to complete the buckling. Further, when the mating shaft 29 is in cooperation with the mating hole on the docking plate 501, it can push the telescopic pressure rod 502, and the first spring 503 exerts a reverse force, that is, exerts a directional force on the mating shaft 29, which can make the buckling state more stable. When disassembling, the control ring 27 can be rotated to make the control gear 32, the rotating shaft 33, and the inclined surface seat 35 rotate. The inclined end surface of the inclined surface seat 35 pushes the contact part 36 to move the buckle plate 30, thereby releasing the buckling state.

[0031] Further, the docking cylinder 24 and the docking plate 501 form a closed space, and the air pressure in the closed space can be adjusted through the air pressure regulating valve 25. For example, the internal air is extracted, and during subsequent operations, the air pressure is monitored in real time through the air pressure detector 26, that is, to detect whether there is a leakage at the docking part.

[0032] The detection assembly moves on pipeline 1 2 and pipeline 2 3, and can detect defects in pipeline 1 2 and pipeline 2 3. Pipeline 1 2 and pipeline 2 3 pass through the moving frame 7, and the contact ball 18 can reduce friction. Specifically, pipeline 1 2 and pipeline 2 3 are generally supported by materials with good toughness and high strength. Conventional visual inspection can only detect obvious defects. In this embodiment, by bending pipeline 1 2 and pipeline 2 3 and detecting the convex area at the bending part, cracks on pipeline 1 2 and pipeline 2 3 can be detected, which is beneficial for further protective measures. Specifically, the traveling motor 9 drives the traveling wheels 12 to move. Inside the moving frame 7, the indexing motor 15 can work, and the indexing ring 17 rotates, that is, rotates around pipeline 1 2. The cleaning control cylinder 19 controls the cleaning part 20 to contact the surfaces of pipeline 1 2 and pipeline 2 3 to remove ash layers, which is convenient for subsequent detection and also for the cleaning and maintenance of pipeline 1 2 and pipeline 2 3. When the adsorption motor 13 works, the dust can be sucked and transported through the adsorption pipe 10 to complete the removal. The bending cylinder 22 controls the bending part 23 to push pipeline 1 2 and pipeline 2 3, and pipeline 1 2 and pipeline 2 3 are bent and deformed. On the opposite side of the bending part 23, that is, the convex area of the bending area faces the detector 21. The detector 21 can check for cracks on the convex area, and thus can effectively check whether there are defective cracks on pipeline 1 2 and pipeline 2 3.
