標準解讀
GB/T 44258-2024 是一項針對土方機械中高原隧道用純電動輪胎式裝載機的國家標準。該標準詳細規(guī)定了此類裝載機的技術(shù)要求、試驗方法、檢驗規(guī)則以及標志、包裝、運輸和貯存要求,旨在確保設(shè)備在高海拔、復(fù)雜隧道環(huán)境下的安全、可靠與高效運作。具體要點包括:
-
適用范圍:明確了本標準適用于工作海拔高度達到或超過2000米,專用于高原隧道施工的純電動輪胎式裝載機。這類裝載機以電池為動力源,設(shè)計需考慮高海拔環(huán)境下氧氣稀薄對電氣系統(tǒng)性能的影響。
-
技術(shù)要求:
- 電動系統(tǒng):規(guī)定了電動機、電池組及管理系統(tǒng)的技術(shù)指標,如續(xù)航能力、充電效率、電池溫控系統(tǒng)等,確保在低溫、低氣壓條件下仍能穩(wěn)定輸出動力。
- 輪胎與底盤:考慮到高原地形的特殊性,對輪胎的耐磨性、抓地力及底盤的穩(wěn)定性、通過性提出了更高要求。
- 環(huán)保與安全:強調(diào)了設(shè)備在運行過程中的低噪音、零排放特性,并對操作安全、緊急制動系統(tǒng)、防翻滾保護等方面做出規(guī)定。
-
試驗方法:詳細說明了如何進行各項性能測試,包括但不限于電動系統(tǒng)的耐久性試驗、高原環(huán)境適應(yīng)性試驗、裝載能力驗證等,確保產(chǎn)品符合設(shè)計要求。
-
檢驗規(guī)則:制定了產(chǎn)品出廠前的檢驗流程與標準,包括型式試驗、出廠檢驗等內(nèi)容,確保每臺設(shè)備在交付前都經(jīng)過嚴格的質(zhì)量控制。
-
標志、包裝、運輸和貯存:規(guī)范了裝載機的標識信息、包裝方式以及在運輸和貯存過程中的注意事項,以防在高海拔運輸過程中因外界條件影響設(shè)備性能。
該標準的實施,為高原隧道施工中純電動輪胎式裝載機的設(shè)計制造提供了統(tǒng)一規(guī)范,有助于提升設(shè)備的整體性能和安全性,促進新能源土方機械在高海拔地區(qū)的應(yīng)用與發(fā)展。
