The invention relates to the technical field of equipment hoisting, in particular to a hoisting system and a hoisting method for crown block overrun equipment in a limited space, comprising an original crown block system, a hoisting mechanism slidably mounted on a trolley track and a reinforcing mechanism arranged between a crown block walking beam and an equipment foundation at an interval; the hoisting mechanism comprises a hoisting frame installed on the trolley track in a sliding mode, the hoisting frame is of a rectangular structure, and hoisting chain blocks are installed at the four corners of the hoisting frame and used for controlling the hoisting height of equipment. A chain block is connected between the limiting stop block and the hoisting frame, and a sliding chain block is arranged on the chain block; the reinforcing mechanism comprises a rectangular frame, and a base plate is filled between the rectangular frame and the crown block walking beam; the plant roof does not need to be dismantled, the operation difficulty is reduced, and the construction expenditures of plant building dismantling recovery and hoisting equipment leasing are saved; the existing structures such as the crown block track and the trolley track are utilized, a sliding track does not need to be reset, and the tool manufacturing cost and time are saved.

    本发明涉及设备吊装技术领域,特别是涉及一种天车超限设备用受限空间内吊装系统及吊装方法,包括原天车系统,还包括滑动安装在小车轨道上的吊装机构和间隔设置天车行走梁和设备基础之间的加固机构;吊装机构包括滑动安装在小车轨道上的吊装框架,吊装框架为矩形结构,吊装框架的四角处均安装有吊装手拉葫芦,用于控制设备吊装高度;限位挡块和吊装框架之间连接有倒链,倒链上设置有滑移手拉葫芦;加固机构包括矩形框架,矩形框架和天车行走梁之间填塞有垫板;无需拆除厂房屋顶,降低了操作难度,节约了厂房建筑拆除恢复、吊装设备租赁的施工经费;利用天车轨道、小车轨道等现有结构,无需重新设置滑移轨道,节省了工装制作成本和时间。
