AI Technical Summary

Technical Problem

The existing observation pipes for the top charging of settling and depletion furnaces are prone to misalignment, making operation laborious and posing a risk of slippage, which affects the convenience and safety of furnace condition inspection.

Method used

A foot-operated observation device for the top of an electric furnace was designed. It adopts a lever transmission structure and multiple limit protections. Through the cooperation of the foot pedal linkage and the fixed pulley, the observation port cover can be easily opened and stably rotated. Combined with the dual limit mechanism of the limit iron ball and the limit ring, the convenience and safety of operation are ensured.

Benefits of technology

It significantly reduces operational intensity, avoids the risk of cover plate misalignment and slippage, improves the convenience and safety of furnace top inspection operations, and the modular design facilitates maintenance.

Abstract

This utility model discloses a foot-operated electric furnace top observation device, including an observation tube. A fixed pulley is provided on one side of the observation tube, and the fixed pulley is connected to a foot pedal linkage via a groove. The foot pedal linkage is connected to a pedal drive shaft. A fixed shaft is provided on the observation tube, and the pedal drive shaft passes through the fixed shaft and connects to an L-shaped observation port cover. The support arm of the L-shaped observation port cover is connected to the fixed shaft, and the cover is positioned above the observation tube. A sliding groove is provided on the support arm of the observation port cover for the pedal drive shaft to slide. A limiting iron ball is provided on the pedal drive shaft, and the range of motion of the limiting iron ball is controlled by a pair of limiting rings. The L-shaped observation port cover is driven to open and close through the linkage structure of the fixed pulley, foot pedal linkage, and pedal drive shaft. The use of limiting rings and grooved slide rails prevents the drive shaft from derailing, and the pedal height of 10-15cm from the ground reduces the risk of slipping. It is suitable for furnace condition inspection of settling / leanening electric furnaces, and features labor-saving operation and high safety.
