300米潜水井钻机履带式设计.doc

摘要
本文设计的300米潜水井钻机采用履带式液压驱动系统,双履带构成钻机的安装支点和基本框架。全液压驱动的控制回路,使其行走和转向机构设计简单、操作方便机构、性能可靠、安全系数较高,更加适用于潮湿等恶劣环境下的工作。
本文对钻机的底盘结构、液压支腿设计计算,特别是对底盘结构在根据理论力学和材料力学进行理论计算的基础之上,并进行了有限元分析。使钻机在满足正常工作前提下,对其底盘结构进行了经济性、制造工艺性等方面进行了优化设计。

Abstract
This article designs 300 meters dive the water well drilling machine to use the marching hydraulic pressure driving system, the double caterpillar band constitutes drilling machine's installment pivot and the bare bone. The entire hydraulic pressure actuation's control loop, causes it to walk is simple with the rotation gear design, the ease of anization, the perform reliably, the safety coefficient are high, even more is suitable for moistly and so on under the adverse circumstance work.
In this paper, the chassis rig structure, hydraulic outrigger and hydraulic control circuit design, especially on the chassis structure in accordance with theoretical mechanics and materials for mechanics on the basis of theoretical calculations and conducted cosmspress finite element analysis. The rig to meet the normal working premise, its chassis structure of the economy, and other aspects of the manufacturing process was optimized.
Keywords: Diving driller; hydraulic drive system; chassis structure; crawler
