Description
Technical Field

Background
In the steel smelting process, oxygen blowing by an oxygen lance is an essential link. In order to ensure the safety of oxygen lance blowing, the oxygen lance transmission equipment adopts a 'double-vehicle double-lance' type.

Each oxygen lance is provided with a lifting trolley and a lifting system which are independent from each other, and a movable guide rail and the lifting system of the oxygen lance lifting trolley are fixed on the transverse trolley, so that the aim of quickly replacing the converting lance and the standby lance is fulfilled. The oxygen lance transverse moving trolley consists of a hoisting lifting platform and a movable guide rail, and when the oxygen lance transverse moving trolley normally works, a lance body and a lifting trolley move up and down along the rail surface of the movable guide rail under the action of a hoisting lifting system. The most widely applied structural form in the existing transverse moving trolley is a single main beam and horizontal reverse roller type structural form, the tipping moment caused by dead weight eccentricity of the trolley and a gun body is born by the horizontal reverse roller, and the vertical wheel only bears the vertical load.
However, as the tonnage of the converter is increased and the diameter of the oxygen lance is increased, the overturning moment is larger and larger, and the horizontal force borne by the horizontal wheel is larger and larger. The problem is often not solved by increasing the horizontal counter roller under the structural restriction of a high-rise frame and equipment.
