新研制的液压整体迈步式吊盘可解决超深立井井筒施工中凿井设备的悬吊问题,为了能使吊盘在井筒施工中具有更好的安全性和可靠性,研制了液压整体迈步式吊盘试验架。主要对液压迈步式吊盘试验架的结构形式及荷载布置进行了分析,通过SAP2000建立模型并进行计算分析,得出试验架立柱上最大的应力比及荷载作用下的轴力图,最后分析得出最大荷载工况下各杆件的应力比,使迈步式吊盘能够可靠进行地面试验。
The newly developed hydraulic step-by-step hanger can solve the problem of shaft sinking equipment in the construction of ultra-deep shaft shaft. In order to make the suspension plate have better safety and reliability in wellbore construction, a hydraulic overall step-by-step Swing plate test stand. The structure and load arrangement of the hydraulic stepping-type test rig are analyzed. The model is established and calculated by SAP2000. The maximum stress ratio of the test stand and the axial force under load are obtained. The final analysis shows Under the maximum load conditions, the stress ratio of each rod, so that the step-type hanging plate can be reliably ground test.
