液壓支架三維CAD系統設計
摘 要
液壓支架是地下工程或隧道工程的關鍵設備之一,它主要用于支護頂板、防止頂板垮落,為施工人員和施工設備提供一個安全可靠的工作空間。隨著國家工程建設規模的擴大和施工進程的加快,對液壓支架的支護性能提出了越來越高的要求。
首先,在分析了傳統液壓支架架型的基礎上,通過機構演化,開發了一種新架型——垂直導桿型液壓支架;該新型支架不僅結構簡單、重量輕和調架容易,而且可極大地改善液壓支架的受力狀況,提高穩定性,具有廣泛的應用前景。
其次,采用三維參數化的設計軟件Pro/E,完成了垂直導桿型液壓支架的三維參數化造型,實現了Pro/E與ADAMS軟件之間的模型轉換,并利用ADAMS軟件對該液壓支架進行了動力學分析,得到了該支架在各種工況下圖形。
關鍵詞:施工機械;液壓支架;垂直導桿機構;三維參數化;ADAMS;
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.
