刮板機是干什么用的
刮(gua)板機(ji)是(shi)煤(mei)(mei)礦采(cai)掘(jue)(jue)工(gong)作面(mian)使(shi)用的運(yun)輸機(ji)械。主要用于采(cai)煤(mei)(mei)工(gong)作面(mian)和(he)采(cai)區順槽運(yun)輸,也可(ke)在(zai)煤(mei)(mei)巷,半煤(mei)(mei)巖巷道掘(jue)(jue)進工(gong)作面(mian)使(shi)用。它能夠向上(shang),也可(ke)以向下運(yun)輸,向上(shang)運(yun)輸一般(ban)不超過35度(du)。向下運(yun)輸一般(ban)不超過25度(du),實際以不超過20度(du)為(wei)宜。
刮板機(ji)(ji)(ji)(ji)具有運(yun)輸能力不受(shou)貨載塊度和(he)(he)濕度影響,機(ji)(ji)(ji)(ji)身高度小便于(yu)(yu)裝(zhuang)(zhuang)載,機(ji)(ji)(ji)(ji)身長度調節(jie)方便,機(ji)(ji)(ji)(ji)體堅固能蹋于(yu)(yu)瀑破裝(zhuang)(zhuang),媒的工作(zuo)面等(deng)優點,所以在多鎮(zhen)煤(mei)礦(kuang)使用較為廣(guang)泛。但它的缺點是(shi):工作(zuo)阻力大(da),耗(hao)電(dian)量大(da),溜槽磨損嚴重,維護和(he)(he)使用不當時易(yi)斷鏈,運(yun)輸距離(li)受(shou)到一定限制。
刮板機結構
主要由以下(xia)幾部分(fen)組成:
(1)驅動(dong)裝置(zhi):包括(kuo)電動(dong)機、減速(su)機、傳動(dong)鏈輪等(deng);
(2)輸送裝置:包括主、從動鏈輪、刮板鏈條等;
(3)外殼。
刮板機使用注意事項
1、操作前必須穿戴好(hao)勞(lao)動保護用品。
2、嚴禁鉆跨護欄,站在刮板拉桿上扒焦炭。
3、禁(jin)止往皮(pi)帶(dai)上放紅(hong)焦。
4、禁止皮帶不運轉時刮料(liao)。
5、設備(bei)檢修時嚴(yan)禁啟動(dong)設備(bei)。
6、禁(jin)止跳護欄和在熄焦軌道(dao)處逗留。
刮板機檢查
1、檢(jian)查溜槽有無磨損、堵塞或其(qi)它不(bu)正常跡象;
2、檢查刮板與底槽(cao)接觸是否良好(hao),有無漏煤;
3、檢查電(dian)動機和減速機的工(gong)作情況(kuang),電(dian)動機不得超過規定溫度,傾聽(ting)牙(ya)輪咬合情況(kuang)、有無跳動和跑偏(pian)現象;
4、檢查大小齒輪,拉板與六角(jiao)輪(lun)咬合(he)是否良好,有無跳動和(he)跑偏現象;
5、檢查各機械軸承的潤滑情況(kuang),檢查各(ge)部(bu)閘門是否靈活,位置是否適(shi)當。
刮板機的安裝標準
刮板機的(de)安(an)裝(zhuang)基準(zhun)線(xian)(xian)(xian)是推焦中(zhong)(zhong)(zhong)心(xin)線(xian)(xian)(xian)、前(qian)(qian)軌(gui)中(zhong)(zhong)(zhong)心(xin)線(xian)(xian)(xian)、標高6260mm平臺(tai)(tai),第(di)(di)一、三臺(tai)(tai)刮板機的(de)機槽(cao)中(zhong)(zhong)(zhong)心(xin)線(xian)(xian)(xian)與前(qian)(qian)軌(gui)中(zhong)(zhong)(zhong)心(xin)線(xian)(xian)(xian)平行,第(di)(di)二臺(tai)(tai)刮板機的(de)機槽(cao)中(zhong)(zhong)(zhong)心(xin)線(xian)(xian)(xian)與前(qian)(qian)軌(gui)、前(qian)(qian)端梁中(zhong)(zhong)(zhong)心(xin)線(xian)(xian)(xian)垂(chui)直相(xiang)(xiang)交,與推焦中(zhong)(zhong)(zhong)心(xin)線(xian)(xian)(xian)、左右側梁中(zhong)(zhong)(zhong)心(xin)線(xian)(xian)(xian)相(xiang)(xiang)平行。安(an)裝(zhuang)時(shi)第(di)(di)一、二臺(tai)(tai)機槽(cao)寬為(wei)(wei)690mm、第(di)(di)三臺(tai)(tai)機槽(cao)寬為(wei)(wei)1000mm,均應以中(zhong)(zhong)(zhong)心(xin)線(xian)(xian)(xian)為(wei)(wei)安(an)裝(zhuang)基準(zhun),偏離(li)中(zhong)(zhong)(zhong)心(xin)線(xian)(xian)(xian)誤差為(wei)(wei)±1.0mm,安(an)裝(zhuang)時(shi)誤差大,就(jiu)會產(chan)生(sheng)刮板與機槽(cao)卡、堵現象。安(an)裝(zhuang)時(shi)連接處螺栓要擰緊、防止松動。
