The invention discloses an ultra-large variable-amplitude pile-frame pile driving barge. The ultra-large variable-amplitude pile-frame pile driving barge comprises a barge body, a pile frame, a closure gap, a variable-amplitude oil cylinder, a hydraulic hammer matching device, a pile holding device and a pile supporting device, wherein the barge body is of a steel box type structure, an object nose bridge is arranged on the bow portion of the barge body, and a variable-amplitude oil cylinder support and a pair of hinged supporting rod supports are arranged on the middle bow portion of a main deck of the barge body; an upper-layer building and a bracket are arranged on the middle stern portion of the main deck of the barge body; ten barge moving winches, seven hoisting winches and two grocery cranes are further arranged on the main deck of the barge body; the pile frame comprises a main frame, a pile hoisting platform, an auxiliary frame and a drop hammer platform; a closure gap backrest mechanism is further arranged on the lower portion of the main frame; the auxiliary frame is of a quadrilateral variable-section truss structure; the closure gap is welded to the middle of the front surface of an upper-layer auxiliary frame platform, a middle-layer auxiliary frame platform, a lower-layer auxiliary frame platform, a ninth-layer main frame platform, a first-layer main frame platform and the front surface of a lower backrest of the closure gap; and the bottom of the variable-amplitude oil cylinder is hinged to a lower hinged support of the variable-amplitude oil cylinder. The pile frame is low in weight, model selection of the variable-amplitude oil cylinder can be facilitated, and the construction cost is reduced.
本发明公开了一种超大型变幅桩架式打桩船,包括船体、桩架、龙口、变幅油缸、液压锤的配套装置、抱桩器和扶桩器。船体为钢箱型结构,船体的艏部设置一对象鼻梁,船体主甲板的中艏部布置变幅油缸支座和一对换铰撑杆支座;船体主甲板的中艉部布置上层建筑和托架;船体主甲板上还布置十台移船绞车、七台起重绞车和两台杂货吊车;桩架包括主架、吊桩平台、副架和吊锤平台;主架下部还设置龙口靠背机构;副架为四边形变截面桁架结构;龙口焊接在上、中、下层副架平台、第九层主架平台至第一层主架平台的前表面中部以及龙口下靠背的前表面上;变幅油缸的底部铰接在变幅油缸下铰座上。本发明的桩架重量轻,能便于变幅油缸选型,降低建造成本。
