摘要
MZ120型液压履带式钻机是一部以建筑土体锚固技术为理论基础的专用工程机械。土体锚固技术以其独特的支护效应、简便的施工工艺,经济的造价而越来越广泛地应用于边坡加固,建筑物的深基坑支挡、坝基稳固、悬索建筑等基础工程中,尤其在深基坑的挡土结构中采用土层锚固技术以占绝对优势。
本次设计主要对液压锚杆钻机的动力头进行了优化设计,通过设计变量的选取,目标函数的构造,约束条件的建立,得出了动力头优化设计的数学模型。采用MATLAB编程、调试、运行,最终获得了动力头的优化尺寸。

Abstract
The hydraulic anchor for soil drilling of the MZ120 is a special-purpose kind of engineering construction machine. The theoretical foundation is the firmness technology. With simple and convenient construction craft and low economic fabrication cost, it has been widely applied to the slope strengthened, the deep base hole of the building supports and blocks, the dam foundation stabilized, hang and ask for building, etc. Especially, adopting the firm technology of the soil layer anchor and blocking the soil structure in the deep base hole, it parative advantage in this filed.
This design mainly has carried on the optimized design to power the head of the hydraulic pressure soil anchor rig. Through design variable selection, objective function structure, restraint condition establishment, the power head to optimize the design the mathematical model has been obtained. Through adopting the programming of the MATLAB, debugging and running, the size of optimization of the motive force head has been obtained finally.
