直埋管抗压强度与轴向滑动试验装置设计

Design of compressive strength and axial sliding performance test device of directly buried steam pipe

通过综合比较国内外现有直埋管抗压强度与轴向滑动试验装置结构特点,根据设计要求,提出了以吸砂机配合砂箱平车分工位完成试验与装砂卸砂的总体设计方案,该装置包括砂箱平车、推拉力试验机、液压加载装置、吸砂系统以及工作梯5个部分。应用三维虚拟建模技术设计砂箱平车、推拉力试验机等机械结构。在虚拟建模基础上,完成砂箱的静态性能分析,校核砂箱的强度和刚度。

Through comprehensive comparison of the structure characteristics of domestic and foreign existing overall compressive strength and axial sliding performance test device of directly buried steam pipe,according to design requirements,the overall design scheme of completing the test and loading and unloading sand in different positions with sand suction machine and sand box flat car is put forward,including the sand box flat car,the push and tensile testing machine,the hydraulic loading device,the sand suction system and the job ladder five parts.Solidworks is used in 3Ddrawing of the device and their components,and AutoCAD is used to transform it into two-dimensional engineering drawings.ANSYS is used in the static analysis of the sand box to check the strength and stiffness.
