【摘要】：随着世界经济的快速增长,高、重、大的基础设施越来越多,这就需要相关的设备来完成。全液压履带桩架的结构紧凑,适用性强,特别是具有承前启后作用的立柱及调整机构,是保障顺利完成施工作用的关键部件。在深入调研的基础上,结合国内外各种履带桩架的结构、机构、优点,设计开发了履带桩架使用的多功能回转立柱。首先结合国内外专业资料,详细分析了各种相关设备的结构、机构原理,进行了作业特点,确定了多功能桩架的总体方案,并确定了多功能桩架的总体参数。其次,根据现场实际情况和发展要求提出了开发多功能回转立柱,确定以多功能回转立柱为主要研究对象,结合施工要求,对立柱作业过程的结构、机构的作用给予详细分析;结合多功能立柱结构的具体情况,推导了计算立柱结构在外荷载作用下,强度、刚度、稳定性。然后,运用三维工程分析软件,分析了多功能回转立柱与起架系统。对立柱结构的应力、应变、位移等进行全面详实的分析。计算结果表明,各项力学(强度、刚度等)和机构(运动干涉等)指标均满足要求。最后分析了对履带桩架的接地面积对整机稳定性的影响;考虑正前方、重心偏向的侧方、行走装置与上车垂直方向三个位置,对履带桩架的稳定分析,确定了履带桩架的稳定域范围。研究开发新型多功能桩架,以满足快速发展的亟需。研究开发新型多功能桩架,可达到一机多用的目的,减少机器占用场地费用,减轻施工企业的负担;同时,由于新型多功能桩架施工效率高,可为企业带来良好效益。新型多功能桩架的开发将提供具有独立自主知识产权的产品,为国家经济建设和一路一带的推进发挥积极作用。
[Abstract]:With the rapid growth of the world economy, more and more high, heavy and large infrastructure, which requires relevant equipment to complete. The compact structure of the full hydraulic crawler pile frame, strong applicability, especially the pillar and adjusting mechanism with the role of preceding and following, is the key component to ensure the smooth completion of the construction function. The structure, mechanism and advantages of all kinds of crawler pile frames inside and outside the country are designed and developed the multi-function rotary column used for the crawler pile frame. First, combining the professional data at home and abroad, the structure of various related equipment, the mechanism principle, the operation characteristics are analyzed in detail, the overall scheme of the multi-function pile frame is determined, and the total function of the pile frame is determined. Secondly, according to the actual situation and development requirements of the field, the multi function rotary column is put forward, and the multi-function rotary column is determined as the main object. The structure of the column operation process and the function of the mechanism are analyzed in detail according to the construction requirements. Under the action of external load, strength, stiffness and stability. Then, the multi-function rotary column and lifting system are analyzed with three-dimensional engineering analysis software. The stress, strain and displacement of the column structure are analyzed and detailed and detailed. The results show that all the mechanics (strength, stiffness, etc.) and the mechanism (motion interference and so on) meet the requirements. After the analysis of the effect of the ground area of the crawler pile frame on the stability of the whole machine, considering the side of the front, the lateral center of the center of gravity, the three positions of the walking device and the vertical direction of the truck, the stability analysis of the track pile frame, the stability range of the track pile frame is determined and the new multi-function pile frame is developed to meet the urgent need of rapid development. The new multi-function pile frame can achieve the purpose of multi use, reduce the cost of the machine and reduce the burden of the construction enterprises. At the same time, the new multi-function pile frame can bring good benefit to the enterprise. The development of the new multi-function pile frame will provide the products with independent intellectual property right, for the national economic construction and the construction of the national economy. The promotion of the whole area plays a positive role.
