液压支架三维CAD系统设计
摘 要
液压支架是地下工程或隧道工程的关键设备之一,它主要用于支护顶板、防止顶板垮落,为施工人员和施工设备提供一个安全可靠的工作空间。随着国家工程建设规模的扩大和施工进程的加快,对液压支架的支护性能提出了越来越高的要求。
首先,在分析了传统液压支架架型的基础上,通过机构演化,开发了一种新架型——垂直导杆型液压支架;该新型支架不仅结构简单、重量轻和调架容易,而且可极大地改善液压支架的受力状况,提高稳定性,具有广泛的应用前景。
其次,采用三维参数化的设计软件Pro/E,完成了垂直导杆型液压支架的三维参数化造型,实现了Pro/E与ADAMS软件之间的模型转换,并利用ADAMS软件对该液压支架进行了动力学分析,得到了该支架在各种工况下图形。

Abstract
Hydraulic power support is one of the important facilities in underground projects or tunnel projects, which is used for supporting top rock, and preventing the top rock from collapsing. It can provide a safe and secure workspace for construction workers and equipments. Along with the scale expansion and high speed of national projects in constructional process, the performance of hydraulic power support need to be increasingly higher and higher. Therefore researching and developing a new type of hydraulic power support is very significant in practice.
Firstly, basing on the analysis of traditional hydraulic power support, by mechanical evolution, a new type of the vertical guide-bar hydraulic power support is developed, and its canopy is also simplified in structure that has no activity side flap. The new support has some advantages: it not only can improve the stress condition, enhance the stability of it, but also possesses of simple structure, light weight, easy adjustment the interval between the adjacent supports. Therefore it is very hopeful in the application prospects.
Secondly, the three-dimensional parametric model of the vertical guide-bar hydraulic power support is set up by using the three dimensional parametric software-Pro/E, this model is translated from Pro/E to ANSYS, and the analysis pictures of both stress and deformation in several static force conditions are got by means of ANSYS software.
