during normal spraying treatment, the lowermost annular block 17 is positioned in the threaded hole 18, the vertical shaft 3 drives the annular block 17 to rotate, the annular block 17 rotates to be matched with the internal thread on the sliding block 5 through the external thread, the sliding block 5 is driven to move upwards, meanwhile, the first pressure spring 21 is pressed to deform, when the sliding block 5 moves upwards, the diameter of the upper end of the conical cavity is smaller than the diameter of the lower end of the conical cavity, so the stop block 6 moves outwards to reset under the action of the pressure of the second pressure spring 24, the stop block 6 can be separated from the annular block 17 due to the outward movement of the stop block 6, and the sliding block 5 and the vertical shaft 3 move downwards under the action of the pressure of the first pressure spring 21 and the gravity of the vertical shaft 3, so that the vertical shaft 3 moves downwards for a specific; namely, the spraying projection 15 and the arc-shaped scraper 16 move downwards at the same time for a certain distance, and the distance of downward movement is the distance between two adjacent annular plates; therefore, the steps are repeated, and the inner wall of the circular female well 34 is continuously coated from top to bottom and is smoothly processed by the arc scraper.
When the spraying projection 15 and the arc scraper move downwards to the same plane with the projection, when the concrete smearing device below meets the embedded projection below the round female shaft 34, the lowest baffle plate is positioned in the sleeve 2 and is positioned at the front side of the stop block 6 when the rotating direction of the sleeve 2 is the same, the stop block 6 is positioned at the outermost end of the displacement, when the first thread block 26 below is separated from the slide block 5, the other adjacent thread block 26 above is matched with the slide block 5, under the rotating action of the thread block 26, the slide block 5 can move upwards to the uppermost end of the displacement, when the thread block 26 continues to rotate along with the vertical shaft 3, because the slide block 5 cannot move upwards, at the moment, the first magnet 30 and the second magnet 31 are positioned at the same angular position, under the attraction force of the first magnet 30 and the second magnet 31, the vertical shaft 3 cannot move downwards, the rotation of the thread block 26 drives the slide block 5 to rotate, the slide block 5 enables the sleeve 4 to rotate and separate from the positioning pin 28, the sleeve 4 rotates together with the vertical shaft 3, the torsion spring 27 is twisted and deformed, when the concrete smearing device is contacted with the pre-embedded protruding part in the manhole, the concrete smearing device can not rotate continuously under the blocking of the protruding part, the blocking plate enables the blocking block 6 to move outwards through the inclined surface on the blocking block 6, the blocking plate is positioned at the rear side of the blocking block 6 with the same rotating direction as the sleeve 4, at the moment, the vertical shaft 3 does not rotate together with the sleeve 4, the first magnet 30 is separated from the second magnet 31, under the torsion action of the torsion spring 27, the sleeve 4 drives the vertical shaft 3 to move reversely, meanwhile, because the first magnet 30 and the second magnet 31 are not attracted any more, the slide block 5 drives the vertical shaft 3 to move downwards together, therefore, the protruding part can be avoided, and simultaneously, after the slide, the stopper 6 stops the downward movement of the annular block 17 so that the vertical shaft 3 cannot move further downward, and thus the vertical shaft 3 moves downward by a distance which is equal to the distance between two adjacent thread blocks 26, and the spraying protrusion 15 and the arc-shaped scraper 16 move downward at the same time. Thereby, the reciprocating rotation treats the inner wall around the protruding portion.
Through the process, when the lower scraper and the spraying protruding part 15 encounter the obstruction of the protruding part, the reverse rotation can be realized, and the normal smearing of the inner wall around the protruding part is realized.
Since the inner wall around the protruding portion is processed only once, the vertical shaft 3 can be moved up to the vicinity of the protruding portion after the entire inner wall of the manhole is processed, and the inner wall in the vicinity of the protruding portion can be processed several times.
After the bottom is coated, the device is taken out.
