一、帶式輸送機是什么

帶(dai)(dai)(dai)式輸(shu)送(song)(song)(song)(song)(song)(song)機(ji)是(shi)以(yi)輸(shu)送(song)(song)(song)(song)(song)(song)帶(dai)(dai)(dai)作牽(qian)引(yin)和承載構件，通(tong)過承載物(wu)(wu)料(liao)(liao)的(de)(de)輸(shu)送(song)(song)(song)(song)(song)(song)帶(dai)(dai)(dai)的(de)(de)運(yun)動(dong)進行(xing)(xing)物(wu)(wu)料(liao)(liao)輸(shu)送(song)(song)(song)(song)(song)(song)的(de)(de)連(lian)續輸(shu)送(song)(song)(song)(song)(song)(song)設備。其結(jie)構原理(li)是(shi)，輸(shu)送(song)(song)(song)(song)(song)(song)帶(dai)(dai)(dai)繞經(jing)傳(chuan)(chuan)動(dong)滾(gun)筒和尾(wei)部滾(gun)筒形成無極(ji)環形帶(dai)(dai)(dai)，上(shang)下輸(shu)送(song)(song)(song)(song)(song)(song)帶(dai)(dai)(dai)由托輥支承以(yi)限制輸(shu)送(song)(song)(song)(song)(song)(song)帶(dai)(dai)(dai)的(de)(de)撓曲垂度，拉緊裝置為輸(shu)送(song)(song)(song)(song)(song)(song)帶(dai)(dai)(dai)正常運(yun)行(xing)(xing)提供所需(xu)的(de)(de)張(zhang)力(li)。工作時(shi)驅動(dong)裝置驅動(dong)傳(chuan)(chuan)動(dong)滾(gun)筒，通(tong)過傳(chuan)(chuan)動(dong)滾(gun)筒和輸(shu)送(song)(song)(song)(song)(song)(song)帶(dai)(dai)(dai)之間的(de)(de)摩擦力(li)驅動(dong)輸(shu)送(song)(song)(song)(song)(song)(song)帶(dai)(dai)(dai)運(yun)行(xing)(xing)，物(wu)(wu)料(liao)(liao)裝在輸(shu)送(song)(song)(song)(song)(song)(song)帶(dai)(dai)(dai)上(shang)和帶(dai)(dai)(dai)子一起運(yun)動(dong)。

帶式輸送機一般是在(zai)端部卸載，當采用專門的卸載裝置時，也可在(zai)中間(jian)卸載。

二、帶式輸送機分為哪幾類

1、按承載能力分類

（1）輕型帶式輸送機：專(zhuan)門應用于(yu)輕型載荷的輸送機。

（2）通(tong)用帶(dai)式(shi)輸(shu)送(song)機(ji)：這是應用最(zui)廣泛的帶(dai)式(shi)輸(shu)送(song)機(ji)，其他類型(xing)帶(dai)式(shi)輸(shu)送(song)機(ji)都是這種帶(dai)式(shi)輸(shu)送(song)機(ji)的變形。

（3）鋼繩芯帶式輸送(song)機(ji)：應用于重(zhong)型載荷的輸送(song)機(ji)。

2、按可否移動分類

（1）固定帶(dai)式輸送機：輸送機安裝在固定的(de)地點，不需要移動。

（2）移動帶式輸送機(ji)：具(ju)有移動機(ji)構(gou)。如輪、履帶。

（3）移置帶式輸(shu)送機(ji)：通過(guo)移動設(she)備變換設(she)備的位置。

（4）可伸縮(suo)帶式輸(shu)送機：通(tong)過儲帶裝置(zhi)改變輸(shu)送機的長度。

3、按輸送帶的結構形式分類

（1）普通(tong)輸送帶帶式輸送機：輸送帶為平型，帶芯為帆布或尼龍帆布或鋼(gang)繩芯。

（2）鋼繩(sheng)牽引帶式(shi)輸(shu)送機(ji)：用(yong)鋼絲繩(sheng)作為(wei)牽引機(ji)構(gou)，用(yong)帶有耳邊的輸(shu)送帶作為(wei)承載機(ji)構(gou)。

（3）壓帶(dai)式輸送機：兩條閉環帶(dai)，其中一(yi)條為承載帶(dai)，另一(yi)條為壓帶(dai)。

（4）鋼帶輸送機：輸送帶是鋼帶。

（5）網帶輸送機：輸送帶是(shi)網帶。

（6）管狀帶式(shi)輸(shu)送(song)機：輸(shu)送(song)帶圍包成管狀或用特殊結構(gou)輸(shu)送(song)帶密閉輸(shu)送(song)物料。

（7）波(bo)狀擋邊(bian)帶(dai)式輸送(song)(song)機(ji)：輸送(song)(song)帶(dai)邊(bian)上(shang)有擋邊(bian)以增大物料的截面，傾(qing)斜角度大時，一般(ban)在橫向設(she)置擋板。

（8）花紋(wen)帶(dai)式輸(shu)(shu)送(song)機：用花紋(wen)帶(dai)以增(zeng)大物料和輸(shu)(shu)送(song)帶(dai)的摩(mo)擦，提高輸(shu)(shu)送(song)傾角。

4、按承栽方式分類

（1）托(tuo)輥式帶式輸(shu)送(song)機：用托(tuo)輥支(zhi)撐輸(shu)送(song)帶。

（2）氣墊(dian)帶(dai)式輸(shu)(shu)送機：用(yong)氣膜支撐輸(shu)(shu)送帶(dai)。另外還有磁(ci)性輸(shu)(shu)送帶(dai)、液(ye)墊(dian)帶(dai)式輸(shu)(shu)送機，它們共同的特點都是(shi)對輸(shu)(shu)送帶(dai)連(lian)續支撐。

（3）深(shen)(shen)槽(cao)型帶式輸送機：由于加大(da)槽(cao)深(shen)(shen)，除用托輥支撐外(wai)，也起到(dao)對物料的夾持作用，可增大(da)輸送傾角。

5、按輸送機線路布置分類

（1）直線(xian)帶式輸送(song)機：輸送(song)機縱向是(shi)直線(xian)，但是(shi)可在鉛垂(chui)面上(shang)有凸凹(ao)變化曲線(xian)。

（2）平面彎(wan)曲帶式輸送機(ji)：可在平面上實現彎(wan)曲運行。

（3）空間彎曲帶式輸送機：可以在(zai)空間實(shi)現(xian)彎曲運(yun)行。

6、按驅動方式分類

（1）單(dan)滾筒驅動帶式輸送(song)機(ji)。

（2）多滾筒驅動帶(dai)式輸送(song)機(ji)。

（3）線摩擦帶式輸送(song)機：用一個或多個輸送(song)帶作為驅動體。

（4）磁性(xing)帶式(shi)輸(shu)送機(ji)：通過磁場作(zuo)用驅(qu)動(dong)輸(shu)送帶。
