平面轉(zhuǎn)彎帶式輸送機(jī)是指采用平輸送帶實現(xiàn)平面轉(zhuǎn)彎的特種帶式輸送機(jī)，也可伴隨著平面轉(zhuǎn)彎進(jìn)行豎向凸凹弧彎曲，構(gòu)成空間轉(zhuǎn)彎。它是通過采取一定的特殊措施使輸送機(jī)運行時產(chǎn)生一個向外的離心推力來克服由轉(zhuǎn)彎造成的輸送帶張力的向心合力，從而保證輸送帶的轉(zhuǎn)彎運行。該平面轉(zhuǎn)彎帶式輸送機(jī)可實現(xiàn)輸送帶的自然變向，而不需采用特殊結(jié)構(gòu)的專用輸送帶。

平面轉(zhuǎn)彎帶式輸送機(jī)的使用可以使得原先無法實現(xiàn)的運輸線路得以實現(xiàn),或者使用常規(guī)膠帶機(jī)方式實現(xiàn)起來非常復(fù)雜的運輸通道得以大大簡化,從而減少轉(zhuǎn)運站的投資,減少污染點、減少設(shè)備故障點、減少維修和操作人員等。可廣泛用于煤炭、冶金、建材、糧食、化工、電力、港口等領(lǐng)域，具有極高的社會效益和經(jīng)濟(jì)效益。

The plane bend belt conveyor is a special belt conveyor which uses flat conveyor belt to realize plane bending, it can also form space bending by performing vertical bending on convex and concave curved segment along with plane bending. It makes the conveyor produce an outward centrifugal thrust during operation to overcome the centripetal composite force of conveyor belt tension resulted from bending by taking certain special measures, thus ensuring the bend running of conveyor belt. This plane bend belt conveyor can realize the natural direction change of conveyor belt without the need of special conveyor belt with special structure.

The use of plane bend belt conveyor can realize the transportation line which cannot be realized on the original conveyor, or make the transportation channel greatly simplified which is very complicated to be realized with conventional rubber belt conveyor, thus lowering the investment for transfer station, reducing pollution points and equipment trouble points, and decreasing maintenance and operation personnel, etc. It can be widely used in fields as of coal, metallurgy, building materials, grains, chemical engineering, electric power, harbor, etc., and has very high social benefit and economic benefit.
