Title: Installation support device for piping
Inventor: USAMI YOSHIAKI
IPC: G06Q50/06
Filed: 1995-04-04
Abstract: PURPOSE: To minimize the stress developed in case of installation and to improve the quality of piping by finding the variation quantities of the directions of error vectors that minimize a composite vector in magnitude, and outputting the variation quantities as the quantities of rotation of the piping corresponding to the error vectors. CONSTITUTION: When pipes 1 and 2 are installed between equipments 1 and 2 in the angle state shown in the figure (b), errors of the pipes 1 and 2 are cumulatively added as they are. For the purpose, when proper angles on the axes of the pipes 1 and 2 are selected, the errors can be prevented from being accumulated. Namely, when the pipe 2 is installed while rotated on the axis by 180 deg. on the basis of the state in the figure (b), the errors of the pipes cancel each other and deflection is eliminated on the whole. Thus, the errors are minimized to suppress the generation of the stress as much as possible. When the number of pipes is large, it is difficult to determine proper angles, pipe by pipe, but the determination of the angles of respective pipes whose errors become minimum is automated to facilitate the determination.
