Adaptive double reamer dredging device

Abstract

The invention discloses a self-adaption double-reamer dredging device. The self-adaption double-reamer dredging device comprises two reamer mechanisms which are arranged in parallel, two transverse movement mechanisms which are arranged perpendicular to the reamer mechanisms, and an amplitude variation mechanism. The two reamer mechanisms both comprise reamers, sleeves, reamer shafts penetrating into the corresponding sleeves and first motors used for driving the corresponding reamers to rotate. The two transverse movement mechanisms both comprise sliding rail bases, two-way screw rods, first sliding blocks, second sliding blocks, guide sliding rails and second motors, wherein the sliding rail bases are arranged perpendicular to the corresponding reamer mechanisms; the two-way screw rods are erected on the corresponding sliding rail bases; the first sliding blocks and the second sliding blocks are arranged on the two-way screw rods in a sleeving mode and can move in the same direction or in the opposite directions; the guide sliding rails are arranged on the corresponding sliding rail bases and used for allowing the first sliding blocks and the second sliding blocks to slide; and the second motors are used for driving the corresponding two-way screw rods to rotate. According to the self-adaption double-reamer dredging device, the distance and angles of the two reamers can be adjusted through the transverse movement mechanisms and the amplitude variation mechanism, and therefore the flexibility of a cutter suction dredger in the cutting work can be improved, missed dredging and secondary pollution are reduced, and the dredging efficiency is improved.

Description

technical field

[0001] The invention relates to a reamer dredging device, in particular to an adaptive double reamer dredging device. Background technique

[0002] A cutter suction dredger is a dredger equipped with a cutter head cutting device, which can be used to excavate almost all types of soil. It can continuously complete dredging, mud transportation, and unloading at one time during work. It is a dredging ship with high efficiency, strong maneuverability and low cost, and it is also the most widely used dredging ship at present. In addition to being composed of a steel structure hull and matching power equipment like ordinary ships, it is also equipped with other dredging equipment according to the actual needs of the work of the cutter suction dredger, mainly including positioning, dredging, dredging and auxiliary dredging. The device has four parts. Dredging equipment is the core of a cutter suction dredger, and the cutter mechanism is the main working mechanism ...
