轻型带式输送机及防逆风装置的研制与应用

针对现有普通带式输送机普遍存在故障点多、成本高、耗电量大、不易铺设和安装等缺陷,结合井下环境特点,研制了一种轻型带式输送机。该轻型带式输送机将原普通带式输送机传动部位改造为以卸载滚筒兼作电动机、联轴器、减速器、传动滚筒的传动装置,极大简化了普通带式输送机传动装置,实现了掘进工作面的集中控制;并利用手动蜗轮张紧装置替代了原有蜗轮、蜗杆张紧装置,使该轻型带式输送机具备结构简单、重量轻、安装维护方便等特点;同时实现了轻型带式输送机与防逆风装置的联锁,能有效防止掘进工作面原煤运输时风量流失,防止风流逆转和瓦斯进入进风流。

Development and Application of Light Type Belt Conveyor and Its Dead Wind Proof Device

In view of defects of more fault points,high cost,big power consumption,uneasy to laid and installation existed in common belt conveyor,a kind of light type belt conveyor was developed according to underground environment condition characteristics.The drive part of common belt conveyor was reformed to driving device which takes unload roller as motors,coupling,reducer and drive roller,which simplifies drive device of common belt conveyor and realizes centralized control of heading face.The manual worm gear tensioning device was used to replace original worm and worm tensioning devices,which make the light type belt conveyor has characteristics of simple structure,light weight,easy installation and maintenance.Meanwhile,the conveyor realizes interlocking with dead wind proof device,which can effectively prevent airloss in coal transportation of heading face,and prevent airflow reversal and gas going into airflow.
