【摘要】：针对目前进口钻机的维护费用较高和周期较长,以及国产钻机的移动性不强等问题,在借鉴了国外同类钻机的成功经验的基础上,本文设计了一种全液压动力头式钻机。整台钻机能够在短时间内拆分为9个相对独立的模块。这种模块化设计降低了钻机的运输要求,解决了现有的国产液压钻机移动性不强的问题。整机的电气系统和液压系统元件大部分采用国产元件,降低了钻机的维护费用,缩短了钻机维修保养周期。本设计完成了如下的设计内容:(1)钻机的主要结构件塔架的结构设计和材料选择。在确定塔架的总体结构后为焊接式桁架结构后,初步选择了构成塔架的钢材型号。分析塔架的两种危险状况下的受力情况。选择然后通过计算机模拟仿真,找出塔架系统的薄弱环节并强化。(2)动力系统的选择。通过对工程机械常用动力输出系统的特点分析,确定本机原动机的为柴油机。而后通过柴油机负载特性曲线及其实际带载测试结果划分出了“柴油机—液压泵”动力系统的稳定工作区域,并确定了实际工作中的柴油机允许转速范围。(3)液压动力头的选择。计算出液压马达的输出参数。而后根据钻探工况和施工要求确定液压动力头的输出参数。选择合适的减速箱、变速箱和液压卡盘,完成液压动力头的选型和搭建。(4)电气系统设计。电气系统包括发动机的监测回路和整机的安全保护回路两部分。发动机监测回路通过发动机的ECM系统和多功能显示器实现。整机安全保护回路以逻辑元件低压继电器为核心。针对不同的安全保护情况,制定不同的安全保护措施;最后绘制了整机的电气原理图。(5)液压系统分管路的设计。分析钻机在部署和施工过程中所需的各个动作。选择能够实现钻机所需的动作的液压执行元件。然后以选定的执行元件为核心搭建各个液压分管路,绘制各个分管路液压原理图。
[Abstract]:Aiming at the problems of high maintenance cost and long period of imported drilling rigs, and the low mobility of domestic rigs, a full hydraulic power head drilling rig is designed based on the successful experience of the same kind of drilling rigs abroad. The whole rig can be split into 9 relatively independent modules in a short time. This modular design reduces the transportation requirements of drilling rigs and solves the problem that the mobility of existing domestic hydraulic drilling rigs is not strong. The electric and hydraulic system components of the whole machine are mostly made of domestic components, which reduce the maintenance cost of drilling rig and shorten the maintenance period of drilling rig. This design has completed the following design contents: 1) the structure design and material selection of the main structure tower of drill rig. After determining the overall structure of the tower as a welded truss structure, the steel model of the tower is preliminarily selected. The stress of the tower under two dangerous conditions is analyzed. The weak link of tower system is found and the selection of power system is strengthened by computer simulation. By analyzing the characteristics of common power output system of construction machinery, it is determined that the prime mover of this machine is a diesel engine. Then, the stable working area of the diesel engine hydraulic pump power system is divided by the load characteristic curve of diesel engine and the test results with actual load, and the selection of the hydraulic power head of the diesel engine with allowable speed range of 3) is determined. The output parameters of the hydraulic motor are calculated. Then the output parameters of hydraulic power head are determined according to drilling conditions and construction requirements. Select suitable deceleration box, gearbox and hydraulic chuck, complete the type selection of hydraulic power head and build the electrical system design. The electrical system includes two parts: the monitoring circuit of engine and the safety protection circuit of the whole machine. The engine monitoring loop is realized through the engine ECM system and multi-function display. The whole machine safety protection circuit takes the logic element low-voltage relay as the core. According to different safety protection conditions, different safety protection measures are worked out. Finally, the electrical schematic diagram of the whole machine is drawn. Analysis of the rig in the deployment and construction of the required actions. Select the hydraulic actuator that can perform the required movement of the rig. Then take the selected actuator as the core to build each hydraulic pipeline, draw the hydraulic schematic diagram of each pipeline.
