The embodiment of the invention discloses an installation construction method for a 280-ton travelling crane. The installation construction method comprises the following steps of checking whether deformation of a high-strength bolt connecting face is within an allowable range or not; rechecking all components used on a main beam according to a drawing; arranging steel stools before assembly, and laying roadbed boxes below the steel stools; assembling and hoisting the main beam; assembling auxiliary beams and end beams of the crane on the ground to form a frame, and integrally hoisting the frame; checking the span, camber and diagonal line of a bridge; checking boundary dimension and the welding condition of a main trolley, and cleaning and grinding all connecting faces; hoisting the whole main trolley; assembling and hoisting an auxiliary trolley; assembling and hoisting a cab and an electric appliance chamber; mounting accessories; mounting a pantograph frame, receiving power at high voltage, debugging power supply and debugging a single body; threading a steel wire rope and installing a load limiter; limiting and restoring, and carrying out whole vehicle joint debugging; and performing trial load and acceptance. By means of the method, the purpose of installing a detached 280T crane part in a new plant is achieved.

    本发明实施例公开一种280吨行车的安装施工方法,包括以下步骤:检查高强螺栓连接面变形是否在允许范围内;对主梁上用的所有构件按图纸进行复查;组装前设置好钢凳,并在钢凳下方铺设路基箱;对主梁进行组装和吊装;在地面对行车副梁和端梁进行组装,形成框架后整体吊装;检查桥架的跨度、拱度、对角线;检查主小车外形尺寸及焊接情况,对所有连接面进行清洗和打磨;对主小车整体进行吊装;对副小车进行组装和吊装;组装并吊装驾驶室与电器室;附件安装;导电弓架安装、高压受电、供电调试、单体调试;穿引钢丝绳并安装限载器;限位恢复并进行整车联调;试载并进行验收,本发明实现了对拆除的280T行车零件在新的厂房安装的目的。
