The invention provides a coke oven top ascending pipe and bridge pipe hoisting and replacing construction technology. The technology comprises the following steps that S1, lifting lugs are evenly arranged on the water receiving seal side of an ascending pipe in the circumferential direction; s2, lifting ropes are arranged on the lifting lugs in a penetrating mode correspondingly, and the connecting points of the lifting ropes are located at the central axis of the ascending pipeline main pipe; s3, connecting each lifting rope connecting point with lifting equipment, and vertically lifting the ascending pipeline to the top of the coke oven; s4, replacing a bridge pipe between the ascending pipeline and the gas collecting pipeline; the lifting lugs are arranged at the water receiving seal end of the ascending pipeline, the lifting ropes penetrate through the lifting lugs respectively, and the connecting points of the lifting ropes are located at the central axis of the main pipe of the ascending pipeline, so that it can be guaranteed that the ascending pipeline is approximately in a vertical state in the lifting process, and the situation that the ascending pipeline is damaged in the lifting process is avoided. And the angle of the rising pipeline needs to be greatly adjusted, so that potential safety hazards exist.

    本发明提供一种焦炉顶部上升管及桥管吊装更换施工工艺,包括如下步骤:S1、在上升管道的接水封侧上周向均匀设置吊耳;S2、在吊耳上分别穿设起吊绳索,各起吊绳索相互的连接点位于所述上升管道主管的中轴线处;S3、连接各吊绳连接点与起吊设备,将所述上升管道垂直吊起至焦炉顶部;S4、更换上升管道与集气管道之间的桥管;该发明在上升管道接水封端设置吊耳,由于在吊耳上分别穿设起吊绳索,各起吊绳索的连接点位于所述上升管道主管的中轴线处,能够保证上升管道在起吊过程中大致位于垂直状态,避免了上升管道在吊升过程中,需大幅调整上升管道角度而存在的安全隐患。
