輸送機自動拉緊裝置

核心提示：今天主要介紹一下四川輸送機自(zi)動拉緊裝置（一）：

輸(shu)送機自動拉(la)緊裝置

今天主要介(jie)紹一下(xia)四川輸送(song)機(ji)自動(dong)拉緊裝置（一）：

     帶式輸(shu)送(song)(song)機在啟動(dong)(dong)和(he)制動(dong)(dong)工(gong)況(kuang)，為保證輸(shu)送(song)(song)帶不(bu)(bu)打滑需要比正常運行工(gong)況(kuang)更(geng)大的輸(shu)送(song)(song)帶張力(li)。自(zi)動(dong)(dong)拉緊裝置，可(ke)根據帶式輸(shu)送(song)(song)機啟動(dong)(dong)、穩定運行、制動(dong)(dong)工(gong)況(kuang)的不(bu)(bu)同(tong)張力(li)要求，自(zi)動(dong)(dong)調(diao)整輸(shu)送(song)(song)帶拉緊力(li)，并自(zi)動(dong)(dong)響(xiang)應拉緊滾筒的位置變化。

自(zi)動(dong)(dong)(dong)式拉緊(jin)(jin)裝(zhuang)(zhuang)置(zhi)包括電動(dong)(dong)(dong)絞車自(zi)動(dong)(dong)(dong)拉緊(jin)(jin)裝(zhuang)(zhuang)置(zhi)、液壓自(zi)動(dong)(dong)(dong)拉緊(jin)(jin)裝(zhuang)(zhuang)置(zhi)和液力絞車自(zi)動(dong)(dong)(dong)拉緊(jin)(jin)裝(zhuang)(zhuang)置(zhi)等。

A：電動(dong)絞車(che)(che)自(zi)動(dong)拉(la)(la)(la)緊(jin)(jin)(jin)裝(zhuang)(zhuang)置(zhi)：電動(dong)絞車(che)(che)主動(dong)拉(la)(la)(la)緊(jin)(jin)(jin)裝(zhuang)(zhuang)置(zhi)由電動(dong)絞車(che)(che)、鋼絲(si)繩、滑輪組、拉(la)(la)(la)緊(jin)(jin)(jin)小(xiao)車(che)(che)、張(zhang)(zhang)力傳感器及電氣系統(tong)(tong)組成(cheng)。電動(dong)絞車(che)(che)自(zi)動(dong)拉(la)(la)(la)緊(jin)(jin)(jin)裝(zhuang)(zhuang)置(zhi)，根據(ju)帶式輸(shu)送(song)機(ji)的(de)(de)(de)啟(qi)動(dong)、穩定(ding)(ding)運行(xing)、制動(dong)工(gong)(gong)況(kuang)分別(bie)設(she)(she)定(ding)(ding)所需的(de)(de)(de)拉(la)(la)(la)緊(jin)(jin)(jin)力。啟(qi)動(dong)前(qian)，拉(la)(la)(la)緊(jin)(jin)(jin)裝(zhuang)(zhuang)置(zhi)按(an)啟(qi)動(dong)工(gong)(gong)況(kuang)輸(shu)送(song)帶的(de)(de)(de)張(zhang)(zhang)力要求(qiu)進(jin)行(xing)拉(la)(la)(la)緊(jin)(jin)(jin)。當(dang)輸(shu)送(song)帶進(jin)入正(zheng)常運行(xing)狀態時，輸(shu)送(song)帶的(de)(de)(de)設(she)(she)計張(zhang)(zhang)力比啟(qi)動(dong)工(gong)(gong)況(kuang)小(xiao)，拉(la)(la)(la)緊(jin)(jin)(jin)裝(zhuang)(zhuang)置(zhi)降低輸(shu)送(song)帶拉(la)(la)(la)緊(jin)(jin)(jin)力，并自(zi)動(dong)保持張(zhang)(zhang)力不變(bian)。輸(shu)送(song)機(ji)在停機(ji)進(jin)入制動(dong)工(gong)(gong)況(kuang)時，拉(la)(la)(la)緊(jin)(jin)(jin)裝(zhuang)(zhuang)置(zhi)自(zi)動(dong)增大拉(la)(la)(la)緊(jin)(jin)(jin)力，以滿足輸(shu)送(song)帶制動(dong)張(zhang)(zhang)力要求(qiu)。自(zi)動(dong)電動(dong)絞車(che)(che)拉(la)(la)(la)緊(jin)(jin)(jin)裝(zhuang)(zhuang)置(zhi)，在啟(qi)動(dong)和制動(dong)工(gong)(gong)況(kuang)能自(zi)動(dong)根據(ju)設(she)(she)定(ding)(ding)的(de)(de)(de)張(zhang)(zhang)力值(zhi)進(jin)行(xing)拉(la)(la)(la)緊(jin)(jin)(jin)力調(diao)整(zheng)。可通過與(yu)輸(shu)送(song)機(ji)系統(tong)(tong)的(de)(de)(de)控制聯動(dong)，實現(xian)對拉(la)(la)(la)緊(jin)(jin)(jin)系統(tong)(tong)的(de)(de)(de)自(zi)動(dong)控制。
