Clamping and positioning device of oxygen lance

氧枪夹紧定位装置

Abstract

The utility model relates to a clamping and positioning device of an oxygen lance, consisting of a pushing head, a hinge, a pushing rod, a base and a hydraulic cylinder. The front end of the pushing rod sheathed on the hydraulic cylinder is hinged with the pushing head by the hinge; the hydraulic cylinder is connected on the base by bolts; and the base is fixed on an oxygen lance cart by a foundation bolt. As the hydraulic transmission is adopted, the clamping and positioning device has fast and accurate action, greatly reduces aligning and positioning time, enhances clamping force, avoids swinging and offset of the oxygen lance, guarantees that the oxygen lance, an oxygen lance opening and a furnace body are on the same central line, thus reducing the labor intensity of operators, eliminating unsafe factors and being beneficial to smooth accomplishment of the blowing process of a rotating furnace.
本实用新型涉及一种氧枪夹紧定位装置,是由推头、铰链、推杆、底座及液压缸组成,套装在液压缸上的推杆前端通过铰链铰接一推头,液压缸用螺栓连接在底座上,底座通过地脚螺栓固定在氧枪小车上。由于采用液压传动,不仅动作快速准确,极大减少了对中定位的时间;而且夹紧力增强,避免了氧枪的摆动和偏移,保证氧枪与氧枪口及炉体始终在同一中心线上。从而减轻了操作人员的劳动强度,消除了不安全因素,有利于转炉吹炼过程的顺利完成。
