ROLLING CORRECTION DEVICE OF SHIELD EXCAVATING MACHINE WITH ROTARY EXCAVATION

摘要

PURPOSE:To permit an excavator to return in reverse rotation while taking the specified position by installing a supporting member fast to the side wall of a pit by a separating/mating means, and rotating a skin plate with rotation of a motor for the desired angle. CONSTITUTION:A plate 14a is elongated by a separating/mating means 14, protruded from a hole in a skin plate 21, and attached by pressure to the side wall 30 of natural ground. At this time, a pulse motor 13 is secured to the side wall 30 of natural ground indirectly. Then the pulse motor 13 is rotated, and the skin plate 21, i.e., the excavator, is rotated through an externally cogged gear 12 and internally cogged gear 11 for an angle corresponding to returning together. When the return with rotating together is completed, the separating/ mating means 14 is separated from the side wall 30 of natural ground by following the opposite procedures. Thereby returning inversive force is obtained without collapsing the side wall 30 of natural ground.
