履帶式液壓鉆機履帶的維護和修理
千(qian)里之行(xing)(xing)始于足下(xia)!履帶式液壓鉆機(ji)的使用壽(shou)命與履帶行(xing)(xing)走機(ji)構(gou)的維護(hu)密不可分(fen)。
軌道(dao)(dao)的使(shi)(shi)用壽(shou)命通(tong)常(chang)取決于軌道(dao)(dao)的張力和調整是(shi)否合(he)理。因此,有必要檢(jian)查上軌道(dao)(dao)的下撓(nao)度(du)(du)。檢(jian)查方法是(shi):先清(qing)理軌道(dao)(dao),在從動(dong)輪頂部(bu)放楔塊,然后啟動(dong)走行軌道(dao)(dao)擠壓楔塊,使(shi)(shi)軌道(dao)(dao)地面下端張緊(jin),松動(dong)部(bu)分上部(bu)向(xiang)(xiang)下偏轉(zhuan)。用直尺測量撓(nao)度(du)(du),法向(xiang)(xiang)撓(nao)度(du)(du)一般為(8~15)mm。
履(lv)(lv)帶(dai)張(zhang)(zhang)緊(jin)總成由油缸、張(zhang)(zhang)緊(jin)梁和(he)(he)張(zhang)(zhang)緊(jin)彈(dan)簧組成。張(zhang)(zhang)緊(jin)方法是:用(yong)高壓油槍從(cong)噴油嘴向油缸內注入鈣基潤(run)(run)滑(hua)(hua)脂(zhi),推動(dong)(dong)活塞,然后推動(dong)(dong)從(cong)動(dong)(dong)輪通(tong)過(guo)張(zhang)(zhang)緊(jin)梁,實(shi)現(xian)履(lv)(lv)帶(dai)張(zhang)(zhang)緊(jin)。當需要放(fang)松時(shi),逆(ni)時(shi)針(zhen)緩慢轉動(dong)(dong)充油閥使(shi)其放(fang)松,潤(run)(run)滑(hua)(hua)脂(zhi)從(cong)排(pai)油口排(pai)出。注意:如果左右履(lv)(lv)帶(dai)下垂(chui)不同,履(lv)(lv)帶(dai)在行駛(shi)時(shi)會發生偏(pian)離(li)。支(zhi)承輪和(he)(he)支(zhi)承輪均采(cai)用(yong)
浮動油封(feng),潤(run)滑油采用(yong)工(gong)業齒輪油。旋(xuan)轉(zhuan)時(shi),密封(feng)圈的一(yi)端(duan)不移動,密封(feng)圈的另一(yi)端(duan)隨車輪旋(xuan)轉(zhuan)。借助(zhu)于(yu)O形圈的張力,將兩個浮環的端(duan)面壓緊,實現密封(feng)。
