Detachable rake head truss for shallow dredging of dredger and shallow dredging method
The invention relates to a detachable rake head truss for shallow dredging of a dredger and a shallow dredging method. The rake head truss is composed of side plates, a rear steel beam, a scraping plate and a support, the side plates are divided into the main side plate and the auxiliary side plate, the main side plate and the auxiliary side plate are located on the two sides of the rear steel beam and the scraping plate respectively, and the rear steel beam, the main side plate, the scraping plate and the auxiliary side plate form a closed rectangular structure. The support is located in the closed rectangular structure and divided into rib plates and inclined plates, the rib plates equally divide the inner space of the closed rectangular structure into a plurality of cavities, the two ends of each rib plate are connected with the rear steel beam and the scraper, and the inclined plates are welded in the cavities divided by the rib plates in a crossed mode. During shallow dredging operation, the rake head trusses are installed on the two sides of a rake head body. The rake head truss is specially designed for mass layer large-area shallow dredging construction of the dredger, the shallow dredging effect and efficiency are improved by increasing the shallow dredging coverage area of a rake head, and the rake head truss has the advantages of being high in strength, small in self weight, simple in structure, convenient to assemble, capable of shortening the construction period, wide in application range and the like.
本发明涉及一种挖泥船扫浅用可拆卸耙头桁架及扫浅方法，耙头桁架由侧板、后钢梁、刮板和支架组成，侧板分为主侧板和副侧板，主侧板、副侧板分别位于后钢梁和刮板的两侧，后钢梁、主侧板、刮板和副侧板组成封闭的长方形结构，支架位于封闭的长方形结构内部，支架分为筋板和斜板，筋板将封闭的长方形结构内部空间等分成若干个腔室，筋板两端连接后钢梁和刮板，斜板呈十字交叉形式，焊接于筋板分割的各个腔室内。扫浅作业时，耙头桁架安装在耙头本体两侧。本发明专为挖泥船在质量层大面积扫浅施工所设计，通过增大耙头扫浅覆盖面积，提高了扫浅效果和效率，具有强度大，自重小，结构简单，装配方便，缩减了工期，适用范围广等优点。
