This invention relates to the field of stainless steel pipe inner wall cleaning technology, specifically to a cleaning device and process for the inner wall of extra-long stainless steel pipes. The device includes a cleaning mechanism, an anti-deviation mechanism, an auxiliary feeding mechanism, and an active feeding mechanism. The cleaning mechanism comprises several rigid pipes. In this invention, motor one and motor two are started synchronously. Motor two drives a directly connected rotating shaft two to rotate, and two meshing gears follow the rotation. Multiple rubber sleeves on the two rotating shafts two cooperate with each other, rubbing against the outer walls of the rigid pipes and the outer walls of the flexible hoses, causing the brush section to move steadily forward inside the stainless steel pipe. Then, the rotating shaft one, directly connected to the motor, drives several sprockets one on its outer side to rotate. Through chain transmission, the sprockets two drive the reel to extend the flexible hose on its outer side. The flexible hose and the brush section move synchronously, thereby preventing the flexible hose from dragging the brush section, avoiding jamming of the brush section, and ensuring cleaning efficiency.

This utility model discloses a convenient bagging support cart, including a lower base plate with three sets of uprights fixedly connected to its top. Connecting rods are inserted into the interior of each of the three sets of uprights, and an upper support is fixedly connected to the top of each of the three sets of connecting rods. Through the interlocking of the three sets of uprights and connecting rods, combined with the lifting components on the connecting frame, the height of the upper support and hooks can be flexibly adjusted.
