Abstract

The invention relates to a smelting reduction furnace main body welding platform which comprises a central platform and a working platform extending outwards based on the central platform, and the working platform is connected with the central platform through a telescopic beam; a base is arranged at the bottom of the central platform; a hydraulic jacking system is arranged at the bottom of the base; and a mechanism for driving the central platform to rotate is also arranged in the base. The invention further provides a construction method of the smelting reduction furnace main body welding platform. The smelting reduction furnace main body welding platform is fixed to the bottom of an MPR furnace; the central platform is lifted to the weld height; the hydraulic rod pushes the working platform outwards to reach the welding seam position; the operation platform is small in size, telescopic and rotatable, linear long welding seam welding is achieved through the point-type small platform, multiple times of height positioning can be achieved through one-time installation, and the scaffold building work is effectively reduced; and the welding work safety is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of welding construction platforms, in particular to a main body welding platform of a smelting reduction furnace. Background technique [0002] The main body of the smelting reduction furnace (MPR furnace for short) is a steel plate welded cylinder structure. This type of furnace body structure uses scaffolding to build a walking platform inside the furnace during the construction of each section of the furnace shell. Due to the large height difference of each layer of the furnace shell, it is necessary to build a construction platform for each additional layer. The walking platform needs a supporting structure. In order to ensure construction safety, it is difficult to build a supporting structure at a higher position, and the supporting structure is complex. Contents of the invention [0003] The present invention aims to solve the above problems, thereby providing a furnace body construction platform ...
