Embodiment Construction

[0016] Depend on figure 1 , figure 2 Visible, the present invention is made up of hook bar 1, seal cover 2, baffle plate 3, guard plate 4 and supporting plate 5. The baffle plate 3 is oval in shape; the sealing cover 2 is circular; the guard plate 4 is a rectangular frame; the lower end of the supporting plate 5 has a right-angled hook.

[0017] The sealing cover 2 is welded on the front of the baffle 1, and the position is concentric with the baffle 1. The supporting plate 5 is welded to the back of the baffle plate 3, the sealing cover 2 is placed on the right angle hook of the supporting plate 5, and a hook bar 1 is respectively connected to both sides of the rectangular frame of the guard plate 4, and the two ends of the hook bar 1 Each has a right-angled hook head.

[0018] The size of the hook bar 1 needs to be determined according to the specific size of the gun head 8 diameter and length, and the length of the inside of the hook bar 1 that the present invention ado...

Abstract

The invention relates to a method for automatically detaching a gun head, which adopts a detacher comprising cant hooks, a sealing cover, a baffle, a protecting plate and a backing plate, wherein the sealing cover is welded in front of the baffle, the backing plate with an elbow bend is arranged behind the baffle, a rectangular protecting plate laps on the elbow bend of the backing plate, and a cant hook is respectively arranged on both sides of the protecting plate. The detaching method of the invention is realized in a way as follows: the hydraulic cylinder piston of the notch gun is used for extruding the notch gun to drive the sealing cover to move, so that the gun head is detached from the notch gun, thereby relieving the heavy manual labor of swinging the sledge hammer, eliminating unsafe factors, avoiding checking accidents, saving energy consumption and ensuring smooth production of blast furnaces. The invention has the advantages of simple structure, low cost, convenient operation, convenience, high speed, easy manufacture and long service life.

Description

technical field [0001] The invention belongs to a mechanical appliance in front of a blast furnace, in particular to a dismantling method for automatically dismantling the nozzle of a blast furnace iron mouth mud gun. Background technique [0002] The gun head is a vulnerable part of the blast furnace tap hole mud gun, and the integrity of the gun head is the key to ensuring the normal sealing of the tap hole. At present, the clay guns in front of blast furnaces used in China generally adopt a monolithic structure, and each gun head weighs 130-150 kg on average. Because the front end of the gun head is often severely burned at high temperature, it needs to be replaced very frequently. According to statistics, an average of about 150 blast furnaces need to be replaced every year. For a long time, the traditional method of manual replacement of nozzles has been used, that is, the furnace workers use a sledgehammer to replace the nozzles. Each replacement requires 5 to 8 peopl...
