Abstract

The invention relates to the field of iron and steel smelting, and relates to an auxiliary device used for an oxygen lance maintenance pressure test. The auxiliary device mainly comprises a maintenance platform (1), roller pedestals (3), and an oxygen lance rotation device (4). The roller pedestals (3) are arranged on the maintenance platform (1). According to the length of the oxygen lance, a plurality of roller pedestals (3) are distributed with certain spaces. Roller seats (5) are arranged on the upper parts of the roller pedestals (3). The oxygen lance rotation device is arranged on a position close to one end of the maintenance platform (1). With the device provided by the invention, automated operations of oxygen lance maintenance and pressure test can be realized, worker labor intensity is reduced, crane frequent use is reduced, working efficiency is improved, and safety risk is reduced.

Description

technical field [0001] The invention relates to the field of iron and steel smelting, and relates to an auxiliary device for welding maintenance and pressure testing after an oxygen lance is used. Background technique [0002] When the oxygen gun is used, the gun head works at a high temperature of about 1700°C. Due to frequent use, regular maintenance is required. When the gun body needs to be repaired horizontally, the oxygen gun is usually placed on the welding structure frame, and the crane is used to cooperate with manual work. Move and rotate the body of the oxygen lance, then overhaul welding and pressure test. [0003] The problem with this method is that it is inconvenient for workers to operate, the work efficiency is low, and the crane needs to be used frequently, which affects other work in the workshop and has certain potential safety hazards. Contents of the invention [0004] The purpose of the present invention is to provide an auxiliary device for oxygen ...
