摘要 FDP－15D型非開挖導(dǎo)向鉆機，是一種全液壓動力頭式導(dǎo)向鉆機。該鉆機主要用于非開挖地下管線的鋪設(shè)工程?？稍诓婚_挖地面的情況下，穿越地表建筑物或地下設(shè)施等障礙（如公路、鐵路、河流、建筑及地下埋設(shè)物等），鋪設(shè)各類地下管線。廣泛是用于通訊、電力、熱力、煤氣及自來水管線的非開挖鋪設(shè)施工。 FDP－15D型非開挖導(dǎo)向鉆機可分為動力站和主機體操縱臺三部分。動力站主要提供高壓液壓油，而主機體就負(fù)責(zé)把液壓油的能量轉(zhuǎn)換為鉆進(jìn)的動力。主機體的設(shè)計重點在于動力頭的設(shè)計。合理的設(shè)計主機體，可提高鉆進(jìn)的效率和鉆機的使用壽命，靈活的結(jié)構(gòu)可以減低鉆機維護(hù)和維修的難度減低使用成本。 關(guān)鍵字：非開挖 導(dǎo)向鉆機 主機體 動力頭 Abstract The FDP－15D type non-dig direction drilling machine, is a kind of whole hydraulic pressure power prinipal type direction to drill machine.Should drill machine to mainly used for to open to dig the earth not the paving engineering of the pipeline.Can cross the earth's surface building or underground facilities etc. obstacle(such as the highway,railroad,river,construct and the underground lay a thing etc.) under the sistuation that not open to dig the earth surface, build each kind of underground pipeline.Extensively is used for not open of communication,electric power,thermodynamic energy,gas and the water pipe line to dig to build a construction. FDP-15D type can be divided into non-dig-rigs and power stations mainframe hardware components. Provide high-pressure hydraulic oil major power stations, and on mainframe hardware for the hydraulic oil to the energy conversion into power. Mainframe hardware design focuses on the first engine design. Reasonable mainframe hardware design can enhance the efficiency and rigs into the life, flexible structures can reduce maintenance and repair rigs used to reduce the difficulty of cost.
