Non-return device of chain belt of pig machine

Abstract

The invention discloses an iron-making blast furnace assorted non-return device of a chain belt of a pig machine, comprising a baffle, a supporting shaft, a supporting seat and a non-return pad, wherein the baffle is arranged on the supporting shaft between two supporting holes of the supporting seat; the circular arc end of the upper part of the baffle locks the shaft sleeve end of a chain belt;the non-return pad is arranged on the front side plate of the supporting seat; when the baffle rotates around the supporting shaft and resets and falls back by dead weight or the chain belt falls andslides back, the lower part of the baffle can not reverse under the blocking which corresponds to the non-return pad. The device is symmetrically arranged below both ends of the chain belt of the upper layer of a pig machine in pairs. In the invention, the design of an unpowered mechanism automatically falling back by the dead weight is adopted, the baffle realizes per se rotation under the touchof the shaft sleeves of both ends of the chain belt, and then the resetting is realized by the dead weight of the baffle; when the chain belt is accidentally broken to fall back and slide back from the high end to the low end, the circular arc end of the upper part of the baffle locks the shaft sleeves of both ends of the chain belt, and the lower part is blocked by the non-return pad, thereby taking the non-return effect and effectively preventing the accidents of serious damage, long-time machine halt, production halt and the like of the pig machine.

Description

technical field [0001] The invention relates to a chain-belt transmission facility of a cast iron machine, which is an accessory equipment of an ironmaking blast furnace, in particular to a chain-belt non-return device of a cast iron machine. Background technique [0002] At present, the supporting cast iron machine for ironmaking blast furnace is driven by the driving wheel to drag the chain belt, and the cast iron mold filled with molten iron is slowly moved to the blanking end by the chain belt for operation. The chain belt is affected by factors such as tensile stress and fatigue wear during operation, and is prone to breakage. Once the chain belt breaks accidentally, the chain belt will fall from the high end to the low end. In this case, the cast iron machine will It will be affected, which can cause downtime and production shutdown accidents, and in severe cases, it will affect the normal production of the blast furnace. Contents of the invention [0003] The prese...
