【摘要】：深井钻机作为技术含量比较高的桩工机械之一,目前在我国的应用日益广泛。因而对深井钻机的重要部件--钻桅结构的研究成为很重要的工作。由于深井钻机钻桅结构受力复杂,很难用解析法计算其结构强度和刚度,所以本文应用Creo3.0M020软件和现场实验测试的方法对X深井钻机的钻桅结构进行系统的研究。通过对X深井钻机钻桅结构的所有实验测点的计算应力与测试应力对比分析结果误差进行统计分析,从而验证X深井钻机钻桅结构的Creo建模方法的准确性。首先,简述本文的选题背景及意义,介绍深井钻机的国内外研究现状。介绍钻机的类型,引出本文研究对象X深井钻机钻桅结构,并且介绍X深井钻机的特点。其次,介绍Creo3.0M020,以内层钻塔为例详细介绍X深井钻机钻桅结构的组成部分由实际模型到几何模型再到计算模型的简化处理过程,介绍风载对X深井钻机工作的影响,介绍X深井钻机的61个计算模型,介绍测点的分布及Creo计算应力。再次,对X深井钻机钻桅结构进行现场实验研究,选取X深井钻机钻桅结构的重要工况即翻转工况和提拉工况进行深入研究。简述了现场实验测点的分布,确定实验测试过程中的初值,简述了测点的分布及测点的测试应力。最后,对X深井钻机钻桅结构Creo结构计算结果与现场实验测试结果进行对比分析,选择X深井钻机钻桅结构的重要工况即翻转工况和提拉工况进行深入对比分析。对比分析了测点的Creo计算应力与现场实验测试应力,并且对所有实验测点计算应力与现场测试应力对比结果的误差进行统计分析,得出Creo中计算出的应力和现场实验测试所得应力相差不大,从而验证X深井钻机钻桅结构的Creo建模方法的准确性。
[Abstract]:As one of the piling machines with high technical content, deep well drilling rig is widely used in our country. Therefore, it is very important to study the structure of drilling mast, which is an important part of deep drilling rig. Because the drillmast structure of deep drilling rig is complex, it is difficult to calculate its structural strength and stiffness by analytic method, so this paper makes a systematic study on the drillmast structure of X deep well drill rig by using Creo3.0M020 software and the method of field experiment test. The accuracy of the Creo modeling method for the mast structure of X deep drilling rig is verified by statistical analysis of the errors between the calculated stress and the test stress at all the experimental test points of the drill mast structure of the X deep well drill rig. Firstly, the background and significance of this paper are briefly introduced, and the research status of deep drilling rig at home and abroad is introduced. This paper introduces the type of drilling rig, introduces the structure of X deep well drill mast, and introduces the characteristics of X deep well drill rig. Secondly, the paper introduces Creo 3.0M020, and introduces the simplified processing process of the structure of X deep well drill mast from actual model to geometry model to calculation model, and introduces the influence of wind load on the work of X deep well drill rig. This paper introduces 61 calculating models of X deep well drilling rig, and introduces the distribution of measuring points and the calculation of stress by Creo. Thirdly, the drilling mast structure of X deep well drill rig is studied in the field, and the important working conditions of the drilling mast structure of X deep well drill rig are studied deeply, namely, the reverse condition and the pulling condition. In this paper, the distribution of field test points is briefly described, the initial values in the course of experimental testing are determined, and the distribution of measuring points and the test stress of measuring points are briefly described. Finally, the Creo structure calculation results of X deep drilling rig are compared with the field test results, and the important working conditions of the drilling mast structure of X deep well drilling rig are compared and analyzed. The Creo calculation stress and the field test stress are compared and analyzed, and the errors between the calculated stress of all the experimental points and the field test stress are statistically analyzed. It is concluded that the stress calculated in Creo is not different from that in field test, which verifies the accuracy of the Creo modeling method for the mast structure of X deep drilling rig.
