52、ctions as item described in item 3.1.12.2 初始料堆。料場(chǎng)沒(méi)有料的情況下 ,要能夠先堆出滿足正常堆料要求的初始 料堆。建立初始料堆的原則是 :Initial material piling is taken place when there are no material piles at the first begging. Then the first qualified material pile should be acquired. The principles are as follows:(1 盡可能保證物料得到均化 ;Ensure the
53、 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 0.8 1.2 米。The top level of the formed initial material pile is requested to decrease from the standard
54、 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 constant and maintained between 0.8 to 1.2m.12.3 殘余料堆恢復(fù)。當(dāng)來(lái)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(lái)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
55、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 recovery Once the material feeding belt conveyor fails, the reclaimer should stop running if the material piles drops to half level of the set value. After the feeding belt is recovered, the stacker can start, and only when the mater
56、ial 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)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 operation To avoid the collision
57、, 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 cantilever in anticlockwise direction reaches 64 degrees. In this case, the stacker should work to recover the material pil
58、es to fulfill the normal operation request, and then the stacker would switch to normal operation mode. 12緊.5 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(lái)料系統(tǒng)已沒(méi) 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(méi)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(lái)料系統(tǒng)停機(jī)。 Emergency material piling When 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 anticlockwise direction reaches 269 degrees, the stacker should not keep revolving
