一、帶式輸送機是什么

帶(dai)式輸(shu)(shu)(shu)(shu)送(song)(song)(song)機是以(yi)輸(shu)(shu)(shu)(shu)送(song)(song)(song)帶(dai)作牽引和承(cheng)(cheng)(cheng)載構件，通過承(cheng)(cheng)(cheng)載物(wu)料的(de)輸(shu)(shu)(shu)(shu)送(song)(song)(song)帶(dai)的(de)運(yun)動(dong)(dong)(dong)進行物(wu)料輸(shu)(shu)(shu)(shu)送(song)(song)(song)的(de)連續輸(shu)(shu)(shu)(shu)送(song)(song)(song)設(she)備。其結(jie)構原(yuan)理是，輸(shu)(shu)(shu)(shu)送(song)(song)(song)帶(dai)繞經(jing)傳(chuan)動(dong)(dong)(dong)滾筒和尾部(bu)滾筒形成無極環形帶(dai)，上(shang)下輸(shu)(shu)(shu)(shu)送(song)(song)(song)帶(dai)由托(tuo)輥支承(cheng)(cheng)(cheng)以(yi)限制(zhi)輸(shu)(shu)(shu)(shu)送(song)(song)(song)帶(dai)的(de)撓(nao)曲(qu)垂度，拉緊裝(zhuang)置為輸(shu)(shu)(shu)(shu)送(song)(song)(song)帶(dai)正常運(yun)行提供所需(xu)的(de)張力。工作時驅(qu)動(dong)(dong)(dong)裝(zhuang)置驅(qu)動(dong)(dong)(dong)傳(chuan)動(dong)(dong)(dong)滾筒，通過傳(chuan)動(dong)(dong)(dong)滾筒和輸(shu)(shu)(shu)(shu)送(song)(song)(song)帶(dai)之間的(de)摩擦力驅(qu)動(dong)(dong)(dong)輸(shu)(shu)(shu)(shu)送(song)(song)(song)帶(dai)運(yun)行，物(wu)料裝(zhuang)在輸(shu)(shu)(shu)(shu)送(song)(song)(song)帶(dai)上(shang)和帶(dai)子一起運(yun)動(dong)(dong)(dong)。

帶式輸送機一般是在端部卸(xie)載，當采用專門(men)的卸(xie)載裝(zhuang)置時，也可在中(zhong)間卸(xie)載。

二、帶式輸送機分為哪幾類

1、按承載能力分類

（1）輕(qing)型帶式(shi)輸送機：專門應用于輕(qing)型載荷的輸送機。

（2）通用(yong)帶(dai)式(shi)輸(shu)送(song)(song)(song)機(ji)：這是應用(yong)最廣泛的(de)帶(dai)式(shi)輸(shu)送(song)(song)(song)機(ji)，其他類型帶(dai)式(shi)輸(shu)送(song)(song)(song)機(ji)都是這種帶(dai)式(shi)輸(shu)送(song)(song)(song)機(ji)的(de)變形(xing)。

（3）鋼繩芯帶式(shi)輸(shu)(shu)送機：應用于重型載(zai)荷的輸(shu)(shu)送機。

2、按可否移動分類

（1）固(gu)定(ding)(ding)帶式輸送機：輸送機安(an)裝在固(gu)定(ding)(ding)的地點，不需(xu)要移動。

（2）移動帶式輸(shu)送機：具(ju)有移動機構。如輪、履帶。

（3）移(yi)置(zhi)帶(dai)式(shi)輸送機(ji)：通過移(yi)動(dong)設(she)備(bei)變換(huan)設(she)備(bei)的位置(zhi)。

（4）可伸縮帶式輸(shu)送機：通(tong)過(guo)儲帶裝置改變輸(shu)送機的長度。

3、按輸送帶的結構形式分類

（1）普通輸送帶(dai)帶(dai)式輸送機：輸送帶(dai)為平型，帶(dai)芯(xin)為帆(fan)布或尼龍帆(fan)布或鋼繩芯(xin)。

（2）鋼(gang)(gang)繩牽(qian)引帶式輸送機：用鋼(gang)(gang)絲繩作為牽(qian)引機構，用帶有耳邊的輸送帶作為承載機構。

（3）壓帶(dai)式(shi)輸送(song)機：兩條閉環帶(dai)，其(qi)中一條為(wei)承(cheng)載帶(dai)，另一條為(wei)壓帶(dai)。

（4）鋼帶輸送(song)機：輸送(song)帶是鋼帶。

（5）網帶(dai)輸送(song)機(ji)：輸送(song)帶(dai)是網帶(dai)。

（6）管狀帶(dai)式輸送(song)(song)機：輸送(song)(song)帶(dai)圍包成管狀或用特(te)殊結(jie)構輸送(song)(song)帶(dai)密閉輸送(song)(song)物(wu)料(liao)。

（7）波狀擋邊帶式輸送(song)機(ji)：輸送(song)帶邊上有擋邊以增大物料的截面，傾斜角度大時，一般在橫向設置(zhi)擋板(ban)。

（8）花(hua)紋帶(dai)(dai)式輸送(song)機：用花(hua)紋帶(dai)(dai)以增大(da)物(wu)料和輸送(song)帶(dai)(dai)的摩(mo)擦，提(ti)高輸送(song)傾角(jiao)。

4、按承栽方式分類

（1）托(tuo)輥(gun)式帶(dai)式輸送機：用托(tuo)輥(gun)支撐輸送帶(dai)。

（2）氣墊帶(dai)式(shi)輸(shu)送(song)(song)機：用氣膜支(zhi)撐輸(shu)送(song)(song)帶(dai)。另(ling)外還有磁性(xing)輸(shu)送(song)(song)帶(dai)、液墊帶(dai)式(shi)輸(shu)送(song)(song)機，它們共(gong)同的特(te)點都是對輸(shu)送(song)(song)帶(dai)連續支(zhi)撐。

（3）深槽型(xing)帶(dai)式輸(shu)送(song)機(ji)：由于加大(da)槽深，除用托輥支撐外(wai)，也起(qi)到(dao)對物(wu)料的夾持作用，可增大(da)輸(shu)送(song)傾角。

5、按輸送機線路布置分類

（1）直線(xian)帶式輸送機：輸送機縱向是直線(xian)，但是可在鉛垂面上(shang)有凸凹(ao)變(bian)化(hua)曲(qu)線(xian)。

（2）平面彎曲(qu)帶式輸送機：可在(zai)平面上實(shi)現(xian)彎曲(qu)運(yun)行(xing)。

（3）空間彎(wan)曲(qu)帶(dai)式輸(shu)送(song)機：可以在(zai)空間實現彎(wan)曲(qu)運(yun)行(xing)。

6、按驅動方式分類

（1）單(dan)滾筒驅動帶式輸送機。

（2）多滾筒(tong)驅(qu)動帶式輸送機。

（3）線摩擦帶(dai)式輸(shu)(shu)送機：用(yong)一(yi)個或多(duo)個輸(shu)(shu)送帶(dai)作為驅動體。

（4）磁性帶式輸(shu)送機(ji)：通過磁場作用驅動(dong)輸(shu)送帶。
