Pig machine chain transmission device

Abstract

The invention discloses a chain gear for a pig machine, which comprises a driving wheel, a driven wheel and a chain belt. The driven wheel has no teeth. The position of teeth is designed to be a smooth circumferential track side; the outer edge of the circumferential track side is designed with a protrudent retainer ring. In this way, when the driving wheel drives the driven wheel to run through the chain belt, the driven wheel, the chain belt and the driving wheel are kept running synchronously all along, and the chain belt does not fall off. The problems that the driving wheel, the driven wheel and the chain belt run asynchronously, and the chain belt falls off for many years are solved through changing the physical design of the driven wheel of the chain gear of the pig machine. Not only the processing cost of the driven wheel is significantly reduced, but also the service life of the driven wheel is significantly prolonged, thus improving the complete use effect of the pig machine. Proved through probation and practice, the physical design of the device is rational, and the device runs stably and reliably through adopting the chain gear of the pig machine, in particular the anti-falling-off structure of the driven wheel.

Description

technical field [0001] The invention relates to a cast iron machine, which is a supporting equipment of an ironmaking blast furnace, in particular to a chain transmission device of the cast iron machine. Background technique [0002] With the development of my country's iron and steel industry, iron casting machines have become important supporting equipment in metallurgical equipment, and they also occupy an important position in the production of iron and steel enterprises. The cast iron machines with fixed rollers used by various domestic iron and steel enterprises, due to the wear and tear of the teeth of the main and driven wheels and the chain belt of the cast iron machine, and the cumulative manufacturing error, etc., the operation of the driving wheel, the driven wheel and the chain belt cannot be synchronized. The driving chain of the driving and driven wheels often falls (climbs) during operation. Once the belt falls during operation, it will cause serious damage t...
