The invention belongs to the technical field of catenary cantilever assembly, and particularly relates to a construction method for preassembling a catenary cantilever based on Revit, which comprises the following steps: selecting a track center line; selecting an overhead line system model to be pre-configured, and obtaining all family and project parameters of the overhead line system model; modifying measurement parameters, drawing parameters and rule parameters; and according to the modified parameters and constraint conditions of each part in the family file, obtaining an overhead line system pre-configuration model meeting all conditions, and calculating pre-configuration parameters involved in the method to purchase components and perform on-site pre-configuration construction. According to the method, the variable parameters are obtained, the geometric constraint model is established, and the position and size of each construction are calculated through the algorithm, so that whether collision occurs between the components can be found in time, and the problems of reworking and material waste are avoided.

    本发明属于接触网腕臂装配技术领域,特别涉及一种基于Revit实现接触网腕臂预配的施工方法,包括选择轨道中心线;选择要预配的接触网模型,获取其所有族及项目参数;修改测量参数、图纸参数、规则参数;依据所修改的参数及族文件中各个零件的约束条件,得的符合所有条件的接触网预配模型及计算出本发明中所涉及的预配参数进行采购构件以及现场预配施工。本发明通过获取变量参数,建立几何约束模型,并通过算法进行各个构建的位置以及尺寸的计算,可及时发现构件之间是否发生碰撞,避免返工以及材料浪费的问题。
