Abstract

The invention relates to the technical field of ship engineering and discloses a dredger. When the dredger is in the working state, main trunnions are mounted on a first low-position trunnion seat anda first high-position trunnion seat correspondingly, so that the minimum and maximum excavation requirements can be met, and switching between the first low-position trunnion seat and the first high-position trunnion seat can also be carried out according to the operation condition, so that the height of the rotation point of a bridge frame is changed, and the work requirements of different digging depths can be met on the same dredger; in the non-working state such as long-time shutdown or dispatching, locking trunnions on the two sides of the front portion of the bridge frame are mounted ina second low-position trunnion seat or a second high-position trunnion seat, and the connection between the front portion of the bridge frame and a ship body is realized; due to the fact that both the main trunnions and the locking trunnions have the selection of two height positions of the low-position trunnion seat and the high-position trunnion seat, maintenance and overhaul operations of thedredger are facilitated; and meanwhile, the requirements of the heavy bridge frame can be met through mutual cooperation of the trunnions and the trunnion seats, and the adaptability of the dredger ishigh.

Description

technical field [0001] The invention relates to the technical field of ship engineering, in particular to a dredger. Background technique [0002] The cutter suction dredger uses a rotating reamer to loosen the soil at the bottom of the river or the seabed, mixes it with cement to form mud, sucks it into the pump body through the dredging pipe, and sends it to the mud discharge area through the mud discharge pipe. [0003] Cutter suction dredger is currently a kind of engineering ship widely used in engineering fields such as dredging waterways and land reclamation. One end of the hull of this type of ship is provided with a slot for installing a bridge device equipped with reamers and other equipment. In the construction state of the cutter suction dredger, the bridge frame rotates at a certain angle around its rotation point, that is, the trunnion, and the end of the bridge frame with the reamer is gradually lowered, so that the reamer can contact with the working area of...
