The principles are as follows:(1) 盡可能保證物料得到均化；Ensure the materials are homogenized.(2) 在 120 °扇形區(qū)域內(nèi)建立初始料堆；The initial material pile should be formed in the 120 degrees sector range.(3) 建立完成的初始料堆的堆頂要 120 °范圍內(nèi)順時(shí)針由標(biāo)準(zhǔn)堆高降到 0，并保證 在正常堆料時(shí)堆料臂

54、卸料點(diǎn)軌跡與堆頂為等落差。堆料臂前端距堆頂高度保持在0.81.2 米。The top level of the formed initial material pile is requested to decrease from the standard level to 0 (bottom) in the 120 degrees sector range clockwise. The parallel distance between the track of the cantilever discharge outlet and pile top level should be const

55、ant and maintained between 0.8 to 1.2m.12.3 殘余料堆恢復(fù)。當(dāng)來料系統(tǒng)出現(xiàn)故障時(shí)，控制取料機(jī)在取到料堆高度只有標(biāo)準(zhǔn) 堆高的 1/2 時(shí)取料機(jī)停止作業(yè)。來料系統(tǒng)故障排除，堆料機(jī)再次起動(dòng)進(jìn)行堆料時(shí)，控制 系統(tǒng)要控制堆料機(jī)將料堆恢復(fù)至正常作業(yè)時(shí)的形狀，即堆頂滿足正常堆料作業(yè)的要求，然后堆料機(jī)轉(zhuǎn)入正常堆料作業(yè)。Material piling recoveryOnce the material feeding belt conveyor fails, the reclaimer should stop running if the material piles

56、drops to half level of the set value. After the feeding belt is recovered, the stacker can start, and only when the material piles level can fulfill the request for normal operation, the reclaimer can be put into operation again.12.4 錯(cuò)位堆料。當(dāng)取料機(jī)運(yùn)行至靠近堆料區(qū)域出現(xiàn)碰撞危險(xiǎn)時(shí)，即取料機(jī)與堆料臂 逆時(shí)針行程起點(diǎn)的夾角為 64 度時(shí)控制系統(tǒng)應(yīng)控制堆料臂自動(dòng)逆時(shí)

57、針位移 55 度，此時(shí)堆 料機(jī)要在按層堆料的形狀下將料堆恢復(fù)至正常堆料作業(yè)時(shí)的形狀即堆頂滿足正常堆料 作業(yè)的要求，然后堆料機(jī)轉(zhuǎn)入正常堆料作業(yè)。Anti-collision operationTo avoid the collision, when the reclaimer runs near the stacker piling region, the stacking cantilever should revolve by 55 degrees anticlockwise if the angel between the reclaimer and the stacking cantil

58、ever in anticlockwise direction reaches 64 degrees. In this case, the stacker should work to recover the material piles tofulfillthe normal operation request, and then the stacker would switch to normal operation mode.12.5 緊急堆料。 當(dāng)取料機(jī)停止工作， 而此時(shí)堆料還在運(yùn)行， 堆料臂逆時(shí)針運(yùn)行的終點(diǎn) 與取料機(jī)的夾角為 269 度時(shí)，控制系統(tǒng)應(yīng)控制堆料機(jī)不再前行。 此時(shí)如來料系統(tǒng)已沒有 物料，應(yīng)控制堆料機(jī)停機(jī)，如還在繼續(xù)給料，要發(fā)出信號(hào)給中控室的同時(shí)，控制堆料機(jī) 分層將物料堆在沒有達(dá)到標(biāo)準(zhǔn)堆高的料堆區(qū)域在。當(dāng)堆料區(qū)堆尾達(dá)到自然安息角37 °時(shí)應(yīng)控制堆料機(jī)及整個(gè)來料系統(tǒng)停機(jī)。Emergency material pilingWhen the stacker is running while the reclaimer system shuts down, if the angle between the reclaimer and the end position of the stacking cantilever in the anticlock
