A Design Method of Symmetrical Beam Type Three-part Steel Bifurcation Pipe

Abstract

The invention discloses a design method of a symmetrical beam type three-part steel bifurcation pipe, which comprises the following steps: step 1, designing the shell shape of the bifurcation pipe; step 2, designing a U-beam; and step 3, designing a waist beam. The invention adopts the drawing method to design the shape of the steel bifurcation pipe, which can improve the design efficiency of water conservancy projects. When designing the pipe shell shape, it is not necessary to deduce the calculation formula of the common point of the intersecting line, and the pipe can be directly drawn by the drawing method in CAD. The shell type ensures that the four intersecting lines can intersect at the same point, which is simple and clear; when designing the shape of U-beam and waist beam, there is no need to obtain the equation of the cone-tube intersecting line, and it is not necessary to derive the U-beam according to the equation of the cone-tube intersecting line The equations of the inner edge, outer edge and outer edge of the waist beam can directly draw the shape of the U-beam and the waist beam through the drawing method in CAD, which is simple and clear; Design of pipelines such as beamless branch pipes.

Description

technical field [0001] The invention relates to the technical field of computer-aided design of water conservancy and hydropower projects, in particular to a design method for symmetrical beam-type three-part steel branch pipes. Background technique [0002] Such as figure 1 As shown, the symmetrical beam-type three-point steel branch pipe is a space obtained by intersecting four conical pipes (main conical pipe 1, left conical pipe 2, right conical pipe 3, and middle conical pipe 4) tangent to the same common tangent sphere. Combined structure, the main pipe 9 and the middle branch pipe 10 are coaxial, the left branch pipe 11 and the right branch pipe 12 are symmetrically arranged along the axis of the main pipe 9 and the middle branch pipe 10, the main pipe 9 is connected with the main tapered pipe 1, and the middle branch pipe 10 is connected with the middle tapered pipe 4. The left branch pipe 11 is connected with the left tapered pipe 2, and the right branch pipe 12 is...

Problems solved by technology

Although this method can accurately design the shape of the steel bifurcation pipe, it is difficult for most engineers and technicians to master the derivation and application of the formula

There are also some literatures that use the combination of drawing method and analytical geometry to design the shape of steel bifurcation pipes. There are many parameters and cumbersome steps, and it is laborious to adjust the shape of bifurcation pipes.
