液(ye)壓(ya)緊(jin)(jin)鏈器(qi)是專為(wei)刮板運輸機設計的(de)一種新型(xing)緊(jin)(jin)鏈器(qi)，使(shi)用(yong)靈活方(fang)便(bian)，操作簡單，緊(jin)(jin)鏈效(xiao)果好，使(shi)用(yong)安全，是目前緊(jin)(jin)鏈器(qi)中使(shi)用(yong)較為(wei)方(fang)便(bian)理想的(de)產品。

對于大功率(lv)、長運距的(de)重型刮(gua)板(ban)輸送(song)(song)機(ji)(ji)而言，刮(gua)板(ban)鏈(lian)(lian)所(suo)需預緊(jin)力很大，閘盤緊(jin)鏈(lian)(lian)器很難(nan)實現。液壓緊(jin)鏈(lian)(lian)器利 用(yong)馬(ma)達(da)提供動(dong)力，帶動(dong)鏈(lian)(lian)輪反轉緊(jin)鏈(lian)(lian)并制(zhi)動(dong)，同時 具有機(ji)(ji)械和電氣閉鎖保護裝置，***性高，適(shi) 用(yong)范圍廣，是一種性能比較完善的(de)刮(gua)板(ban)輸送(song)(song)機(ji)(ji)緊(jin)鏈(lian)(lian) 裝置，礦(kuang)用(yong)液壓緊(jin)鏈(lian)(lian)器，特別(bie)適(shi)用(yong)于重型刮(gua)板(ban)輸送(song)(song)機(ji)(ji)的(de)鏈(lian)(lian)條張緊(jin)。

緊鏈過程

緊鏈(lian)(lian)前(qian)，首先用阻(zu)鏈(lian)(lian)器將刮(gua)板(ban)(ban)鏈(lian)(lian)固(gu)定(ding)，壓(ya)下回(hui)轉(zhuan)機架使(shi)馬達(da)(da)(da)緊鏈(lian)(lian)裝 置進(jin)入正確嚙(nie)合(he)(he)狀態，并檢查惰輪(lun)和大齒輪(lun)嚙(nie)合(he)(he)間 隙是否合(he)(he)適；然后向(xiang)液(ye)壓(ya)控制閥(fa)(fa)供(gong)(gong)液(ye)，操(cao)作(zuo)液(ye)壓(ya)控 制閥(fa)(fa)手(shou)柄(bing)至相應位置，液(ye)壓(ya)馬達(da)(da)(da)轉(zhuan)動，刮(gua)板(ban)(ban)鏈(lian)(lian)低速 反(fan)轉(zhuan)，隨著刮(gua)板(ban)(ban)鏈(lian)(lian)張(zhang)緊力(li)加大，液(ye)壓(ya)馬達(da)(da)(da)轉(zhuan)速變得 十分緩(huan)慢，注意觀(guan)察刮(gua)板(ban)(ban)鏈(lian)(lian)的張(zhang)緊程度，直(zhi)到拖出的刮(gua)板(ban)(ban)鏈(lian)(lian)足夠松弛，將液(ye)壓(ya)控制閥(fa)(fa)手(shou)柄(bing)扳(ban)到中位制 動，馬達(da)(da)(da)停(ting)轉(zhuan)，此(ci)時可(ke)以安全地增減(jian)鏈(lian)(lian)環，調整(zheng)刮(gua)板(ban)(ban)鏈(lian)(lian)長度；接鏈(lian)(lian)完成后將液(ye)壓(ya)控制閥(fa)(fa)手(shou)柄(bing)扳(ban)至與緊鏈(lian)(lian)操(cao)作(zuo)相反(fan)位置，使(shi)馬達(da)(da)(da)正向(xiang)運(yun)轉(zhuan)拉鏈(lian)(lian)，當阻(zu)鏈(lian)(lian)器固(gu)定(ding)的上(shang)鏈(lian)(lian)松動時，操(cao)作(zuo)液(ye)壓(ya)控制閥(fa)(fa)手(shou)柄(bing)至中位停(ting)止(zhi)向(xiang)液(ye)壓(ya)控制閥(fa)(fa)供(gong)(gong)液(ye)，馬達(da)(da)(da)停(ting)止(zhi)運(yun)轉(zhuan)；取下阻(zu)鏈(lian)(lian)器，操(cao)作(zuo)液(ye)壓(ya)控制閥(fa)(fa)轉(zhuan)動鏈(lian)(lian)輪(lun)，使(shi)張(zhang)緊力(li)均衡(heng)； 后斷(duan)開緊鏈(lian)(lian)系統(tong)，使(shi)惰輪(lun)與大齒輪(lun)脫離嚙(nie)合(he)(he)。
