Abstract

The invention discloses a gantry type grab dredger which comprises a dredger body, a gantry crane, a dredge pump and a processing device, wherein a sludge storage cabin is arranged on the dredger body; the gantry crane, the dredge pump and the processing device are mounted on the dredger body; a dredging grab is arranged on the gantry crane; the processing device is used for processing sludge; the sludge storage cabin is used for storing the sludge after being processed by the processing device; and the dredge pump is used for pumping the sludge to a blowing filling area or a sludge barge from the sludge storage cabin. The gantry type grab dredger is high in operation efficiency, can operate under deep water and can process hard soil and stone.

Description

technical field [0001] The invention relates to the field of ships, in particular to a gantry type grab dredger. Background technique [0002] At present, the commonly used types of dredgers mainly include full-turn grab dredgers, cutter suction dredgers, and trailing suction dredgers. The full-turn grab dredger mainly grabs the mud by the grab, and then lifts, luffs, turns, and opens the grab to unload the mud to complete the work. At the same time, it needs to be equipped with a special mud barge; cutter suction dredger, trailing suction and The cutter rake dredger mainly works through the dredging and mud blowing system. [0003] The dredgers in the prior art all have deficiencies, the full-turn grab dredger: low work efficiency, need to be equipped with special mud barges, and high operating cost. Cutter suction dredger: The operating depth is limited, and the general operating water depth can only reach 30m, which cannot meet the requirements of deep water operation. ...
