A prefabricated direct-buried heat-insulating pipe joint outer protective tube surface cleaning treatment device

Abstract

The application discloses a prefabricated direct-buried heat preservation pipe jointing surface cleaning treatment equipment, which comprises a rack and a transmission shaft, the transmission shaft is installed on the rack through a bearing and a bearing seat, the rack is installed with a driving assembly for driving the transmission shaft to rotate, one end of the transmission shaft is installed with a first fixing disc, the middle part of one side of the first fixing disc is installed with a second fixing disc, at least one outer cleaning mechanism is installed on the outer side of the first fixing disc which is located on the outer side of the second fixing disc, and the second fixing disc is installed with an inner cleaning mechanism. Through coaxial rotation structure design of the inner and outer cleaning mechanisms, the application can realize synchronous cleaning of the outer wall and the inner wall of the pipeline at the same time, operation is not interfered, and the surface treatment efficiency of the prefabricated direct-buried heat preservation pipe before jointing is obviously improved. Through cooperation of the elastic extension and the guiding and stabilizing structure, the inner cleaning mechanism can stably and tightly press the inner wall with the cleaning pad, and the inner wall is cleaned uniformly and reliably.
