Abstract
The invention discloses a quick-replaceable main drive seal structure of a shield machine. The main drive seal structure comprises a welded base plate, a sealing wear-resisting plate, a sealing fixed plate, a lip seal, an inside sealing pressing plate, an outside sealing pressing plate and a sealing connecting plate, wherein the inner end face of the welded base plate is fixed to the outer end face of a cutter head flange; the inner end face of the sealing wear-resisting plate is fixed to the outer end face of a main drive frame; two ends of the lip seal are fixed to the inner end face of the sealing fixed plate by means of the inside and outside sealing pressing plates respectively; and the inner side face of the sealing fixed plate is engaged and located on the outer side face of the welded base plate. The quick-replaceable main drive seal structure of the shield machine is simple and low in cost investment; the structure is quite convenient to mount, demount and replace, so that the maintenance time and the maintenance cost are greatly reduced, and the maintenance efficiency and the convenience are improved; and the structure can be additionally arranged on the basis of the previous main drive structure of the shield machine to protect the previous seal system, and the structure can be replaced quickly after being damaged, so that the transformation and upgrading of equipment are facilitated, and the cost is saved.
