Stroke conversion device for iron notch drilling machine for blast furnaces

用于高炉开铁口机的行程转换装置

Abstract

The utility model relates to a stroke conversion device for an iron notch drilling machine for blast furnaces, which comprises an outer casing. The outer casing is provided with a first worm and a second worm inside. A tension steel wire with one end fixedly connected with the first worm is wound on the first worm. The other end of the tension steel wire penetrates through the outer casing and exposes out of the outer casing. The first worm is provided with a reset spring and is in mesh transmission with the second worm through a speed-variable gear. A shaft of the second worm extends out of the outer casing to form an output end. The stroke conversion device can be mounted in a safety area distant from the blast furnaces and can be connected with detection equipment, action stroke of an action device of the iron notch drilling machine is converted into angular displacement by the stroke conversion device, and automation and standardization of control of the iron notch drilling machine are realized beneficially.
本实用新型涉及一种用于高炉开铁口机的行程转换装置,包括外壳,外壳内设有第一、第二蜗杆,第一蜗杆上绕有一端与之固定连接的牵拉钢丝,牵拉钢丝的另一端穿过外壳露出端头,第一蜗杆上还设有复位弹簧;第一蜗杆经变速齿轮与第二蜗杆形成啮合传动;第二蜗杆的轴伸出外壳形成输出端。本实用新型可以安装在远离高炉的安全区域,可与检测设备相连,并将开铁口机动作装置的动作行程转换为角位移,有利于实现开铁口机控制的自动化和标准化。
