I 摘要 針對傳統(tǒng)鉆探行業(yè)施工過程中設備搬遷困難、鉆孔效率低以及無法傾斜 鉆探等問題，研制、改進新一代高效可傾式鉆探設備則顯得尤為必要。該礦用 鉆機改型過程中所面對的若干問題進行了較為詳細研究，并對關鍵件加工過程 出現(xiàn)的工藝文體進行分析和調(diào)整。 通過調(diào)研了解到，對鉆孔深度 100 米左右的鉆機需求量比較大，而目前 的 100 米鉆機，存在著勞動強度大、適應性差等缺點。鑒于以上原因，我們決 定開發(fā) 100 米鉆機。經(jīng)幾次方案討論決定，鉆機應具有以下特點：經(jīng)濟耐用可 靠、質(zhì)優(yōu)價廉；便于解體搬運；體積小，重量輕；操作簡單，維修方便；適用 于 42、50mm 兩種鉆桿； 適用于合金鉆頭或金剛石鉆頭鉆進；鉆進速度快，效率高；動力為電機或柴油 機。 關鍵詞:100 米 變速箱 鉆機 II Abstract the equipment moves the difficulty in view of the traditional drilling profession construction process in, the drill hole efficiency lowers as well as is unable to incline questions and so on drilling, the development, improves new one generation highly effective to be possible to lean the type drilling equipment to appear especially essential. In this mineral product drilling machine modification process faces certain questions have conducted the comparatively dissect, and the craft literary style which appears to the key processing process carries on the analysis and the adjustment. Understood through the investigation and study, quite is big to the drill hole depth 100 meter about drilling machine demands, but the present 100 meters drilling machines, have the labor intensity in a big way, the compatible inferior shortcoming. In view of the fact that above reason, we decided develops 100 meters drilling machines. Decided after several plan discussions that, the drilling machine should have following characteristic: economy durable reliable, high quality at low price; is advantageous for the disintegration transporting; the volume is small, the weight is light; the operation is simple, the service is convenient; is suitable for 42, 50mm two kind of drill rods; is suitable in the alloy drill bit or the carbon bit sneaks in; sneaks in the speed to be quick, the efficiency is high; the power is the electrical machinery or the diesel engine. Kewords: drilling machines 100 meters gearbox III 目 錄 摘要 ...........................................................................................................................
