Abstract

The utility model provides a gun head dismounting tool for a blast furnace gun, which comprises an ejecting plate which is a blocking main body and is used for being attached to the end part of a gun head to apply an abutting force to the gun head, a clamping plate is arranged on one side of the ejecting plate and is of a frame-shaped structure, and the inner side wall of the clamping plate is matched with the joint of a gun body and the gun head of the gun. The clamping plate is used for being clamped and positioned at the joint of a gun body and a gun head of the clay gun, and the two connecting plates are arranged on the two sides of the jacking plate and the two sides of the clamping plate respectively and used for connecting the jacking plate with the clamping plate so as to form a structure for applying force to disassembly of the gun head. The gun head is stably disassembled through axial thrust generated by mud jacking pressure in the mud gun, traditional hammering is replaced, the situations that metal scraps splash, the gun head falls off to hurt people, the connecting position of equipment deforms and a sealing piece loses efficacy due to impact force are avoided, and disassembling safety and equipment reliability are improved.
