The paths along which the at least two detection blocks 300 slide with respect to the mounting base 200 should intersect at a point, which can be considered as the center of the pipe 100 when the pipe 100 is inspected. When the detection blocks 300 slide relative to the mounting base 200, the end parts of the detection blocks can be in contact with the outer side wall of the pipe 100, when one ends of all the detection blocks 300 are in contact with the outer side wall of the pipe 100, the mounting base 200 can drive the detection blocks 300 to move along the axial direction of the pipe 100, and when the detection blocks 300 pass through the opposite opening of the pipe 100, whether the opposite opening exists in the opposite opening or not can be detected.
The term "staggered" means that the axes of the two pipes 100 are staggered when they are connected, resulting in a step structure at the opposite ends of the pipes 100, and the term "folded" means that the axes of the two pipes 100 are inclined to each other when they are connected, resulting in the two pipes 100 being inclined to each other.
Because the number of the pipes 100 on the heating surface of the power plant boiler is large, the pipe diameters of the pipes may be different, and therefore, when the pipes 100 with different pipe diameters are detected, the pipe aligning inspection tool needs to be properly adjusted. The pipe aligning inspection tool disclosed by the embodiment comprises at least two inspection blocks 300, when in inspection, the inspection end of the first inspection block 300 is abutted against the pipe 100, the mounting base 200 is adjusted to move relative to the pipe 100, when the mounting base 200 moves, the other inspection blocks 300 are driven to move, when the center line of the other inspection blocks 300 passes through the circle center of the pipe 100, the first inspection block 300 is fixed with the mounting base 200, then the other inspection blocks 300 are slid until the inspection ends of the other inspection blocks contact with the pipe 100, then the inspection blocks 300 are also fixed, at the moment, the pipe aligning inspection tool is only pushed to move along the axis of the pipe 100 and pass through the pipe orifice of the pipe 100, and whether the aligning between the two pipes 100 has a wrong opening or a folded opening can be inspected. This kind of pipe is to mouthful inspection tool can once inspect the mouth of pipe 100 from a plurality of directions, and one-time through can checking out whether the mouth of pipe 100 has a wrong mouth or a discount mouth, need not the inspection many times, and the promotion efficiency of inspection that can be very big saves check-out time, simultaneously, because of its angle of inspection at the same moment is more, therefore its measurement accuracy is also very high, can be more accurate the judgement pipe 100 have a wrong mouth or a discount mouth to the mouth.
In this embodiment, the number of the detecting blocks 300 may be two or at least three, when at least three detecting blocks 300 are provided, the sliding paths of the detecting blocks 300 may be in any direction, as long as the sliding paths of the detecting blocks 300 are finally compared with a point, the end of the detecting block 300 can be abutted against the outer side wall of the pipe 100 and tangent to the outer side wall of the pipe 100, and at this time, the detecting blocks 300 are moved relative to the pipe 100, so that whether the pipe 100 has a wrong opening or a folded opening at the opposite opening can be detected.
When the two detection blocks 300 are provided, the sliding paths of the two detection blocks 300 are inclined to each other, which also ensures that the alignment of the pipe 100 can be checked from multiple directions when the pipe alignment inspection tool moves along the axis of the pipe 100, thereby accurately judging whether the pipe 100 has a wrong or folded opening at the alignment.
