The invention relates to the technical field of blast furnace maintenance, and discloses a blast furnace maintenance platform and a cooling wall replacement method. A gear wheel is in rolling contact with a furnace mouth steel ring, and the rolling direction is horizontal; a rotating frame is arranged on the gear wheel, the rotating frame is driven by a chain block, and the chain block drives the rotating frame to horizontally rotate along the furnace mouth steel ring; a first winch and a second winch are arranged on the rotating frame, the steel wire rope ends of the first winch and the second winch are connected with a lifting platform, and the lifting platform is used for bearing workers to install the cooling wall; a hanging beam is arranged on the steel frame upright post between the blast furnaces, a hoist beam is arranged on the hanging beam, and a central winch is arranged on the hoist beam; the maintenance platform is arranged above the furnace mouth steel ring, an operator can enter the furnace from the lifting platform to install the cooling wall, the cooling wall can be hoisted to a designated position in cooperation with the rotating frame, the replacement mode is good in safety, the main line construction time can be shortened, a protective shed does not need to be erected, and a furnace shell does not need to be damaged.

    本发明涉及高炉维修技术领域,公开了一种高炉维修平台及冷却壁更换方法,档轮与炉口钢圈滚动接触,滚动方向为水平;档轮上设有旋转框架,旋转框架通过倒链进行驱动,通过倒链带动旋转框架沿炉口钢圈进行水平旋转;旋转框架上设有第一卷扬和第二卷扬,第一卷扬和第二卷扬的钢丝绳端连接有升降平台,升降平台用于承载工作人员安装冷却壁;在高炉之间的钢架立柱上设有吊挂梁,吊挂梁上设有葫芦梁,葫芦梁上设有中心卷扬;本申请在炉口钢圈上方设置维修平台,操作人员能从升降平台进入炉内安装冷却壁,并且配合旋转框架能将冷却壁吊运到指定位置,这样的更换方式安全性好,能缩短主线施工时长,且不用搭设保护棚,也不用破坏炉皮。
