Ship pipeline support and hanger rapid statistics and plotting method based on three-dimensional model

Abstract

The invention discloses a ship pipeline support and hanger rapid statistics and plotting method based on a three-dimensional model, wherein the method comprises the following steps: building a pipeline support and hanger model, and enabling installation information parameters of pipeline supports and hangers to be matched in the three-dimensional model; laying the pipeline support and hanger model, wherein the pipeline supports and hangers need to be classified and laid under the corresponding assembly nodes according to statistics and plotting requirements; numbering the pipeline support andhanger model, and writing numbering information into model attributes; exporting pipeline support and hanger statistical information: performing projection transformation on the pipeline support and hanger model, establishing a mapping relationship between different view angle projection drawings of the pipeline supports and the corresponding simplified symbols, and transforming the projection drawings of the pipeline support and hanger model into the corresponding pipeline support and hanger simplified symbols; and quickly labeling a pipeline support and hanger installation drawing. The method has the beneficial effects that automatic statistics of the specifications and the number of the pipeline supports and hangers is achieved, rapid plotting of the pipeline support and hanger installation drawing is achieved according to the plotting requirements of the pipeline supports and hangers, and the design quality and efficiency of a pipeline system are greatly improved.

Description

technical field [0001] The invention belongs to the field of ship system and digital design, and in particular relates to a three-dimensional model-based fast statistics and drawing method for ship pipeline supports and hangers. Background technique [0002] The ship pipeline support and hanger is also called the pipeline horse foot. It is a complex assembly composed of clamp rings, brackets (hangers), vibration isolation pads, vibration isolators and other components. Its main function is to bear pipeline loads, Constraining pipeline deformation and controlling pipeline vibration are important components of the ship's fluid pipeline network system. The design of pipeline supports and hangers directly affects the fluid characteristics, impact resistance performance and vibration and noise control effect of the pipeline network, and is an important content in the design of ship systems. [0003] In the design of the ship system, the pipeline supports and hangers are distribu...

Problems solved by technology

In the current ship digital design, model-based statistics and drawing are limited to the statistics of the number, length and weight center of gravity of the model and the simple projection of the model. Although this method can reduce part of the workload, due to the lack of pertinence, Designers still need to spend a lot of time and energy on data collation and editing and modification of drawing information in the later stage, so it is necessary to optimize the whole process
