Problems solved by technology
[0003] At present, during the disassembly and relocation process of the lower material flow control valve, the main workload is the relocation after dismantling and before installation. Each relocation needs to be repeatedly shifted by using a hand chain hoist. The unlucky work after dismantling and before installation requires more construction time, lower labor efficiency and greater safety risks

The invention provides a disassembly device and disassembly method for a blast furnace lower material flow regulating valve. The disassembly device includes: a top rail; a bottom rail; a long support arm, and the long support arm includes a The connected beam part and the inclined beam part integrally formed with the cross beam part and extending toward the top track; the first walking assembly, the first walking assembly includes a first axle detachably connected with the inclined beam part; the short support arm, the short support arm and The bottom of the lower material flow regulating valve is fixedly connected and extends to the bottom track; the second walking assembly includes a second wheel shaft detachably connected to the short support arm; the traction assembly includes a second axle that is fixedly connected to the lower material flow regulating valve The connecting ear and the traction rope detachably connected with the connecting ear; traction device; lifting device. The invention can greatly improve the disassembly efficiency of the lower material flow regulating valve, reduce the labor cost, and reduce the safety risk of disassembling and assembling the lower material flow regulating valve.
Description
technical field [0001] The invention relates to the technical field of blast furnace maintenance, in particular to a disassembly device and a disassembly method for a blast furnace lower material flow regulating valve. Background technique [0002] As the key equipment of the blast furnace top material distribution system, the tank-merging blast furnace lower material flow regulating valve is used to transfer the material in the top weighing tank to the furnace. Since the blast furnace needs to carry out uninterrupted material distribution during the production period, the lower material flow regulating valve is the key channel of the furnace top material. Under the erosion of long-term material circulation, the inner lining or surface of the blast furnace is damaged to varying degrees. During the repair period of the blast furnace, The damaged lower flow regulating valve needs to be replaced as a whole. Because the blast furnace adopts the tank-merging system for material ...
