Abstract (en)
A vertically movable thruster apparatus includes: a pair of racks (31) of required length which are disposed, respectively, on outer surfaces of a canister (21) and each of which has tooth sections (32) of constant pitch in the vertical direction; guide members (40) which are disposed along the racks (31), respectively; and a pair of elevation devices (30) for vertical movement of the canister (21) in a vertical passageway (2). Each of the pair of the elevation devices (30) includes: a pair of upper and lower catches (36), (38) which are respectively independently brought into fitting engagement and disengagement with tooth sections (32) at positions vertically spaced apart; a pair of upper and lower frames (34), (35) equipped with the catch (36) and the catch (38), respectively; and an elevation cylinder (33) arranged between the frames (34), (35). The elevation cylinder (33) is configured such that, with respect to one of the frames (34) firmly fastened to the vertical passageway, the elevation cylinder moves the other frame (35) vertically using the guide member (40) as a guide. According to this construction, the thruster can be raised to a position above a waterline.
