Pipe axis pay-off device and pay-off method

Abstract

The invention discloses a pipeline axis setting-out device. The pipeline axis setting-out device mainly comprises a fixed mechanism, an angle locating mechanism and a setting-out mechanism, wherein the fixed mechanism is arranged on the end surface of a main pipeline; the angle locating mechanism is arranged on the fixed mechanism located in the center of the end surface of the main pipeline; the center of the angle locating mechanism is rotatably connected to the fixed end of the setting-out mechanism; the length direction of the setting-out mechanism is perpendicular to the axis of the main pipeline; and a line laser emission instrument is arranged on the free end of the setting-out mechanism. The invention also discloses a pipeline axis setting-out method. The pipeline axis setting-out device and the pipeline axis setting-out method have the beneficial effects that the setting-out mechanism can be quickly arranged on the main pipeline through the fixed mechanism and is accurately located through the angle locating mechanism, thereby ensuring the accurate setting-out of branch pipeline axes, providing foundation for follow-up setting-out of intersecting lines, improving installation accuracy and ensuring installation quality of intersecting pipelines.

Description

technical field [0001] The invention belongs to the technical field of pipeline construction, and in particular relates to a pipeline axis line releasing device and a line setting method. Background technique [0002] When multiple pipes are connected, the envelope formed by the junction between the pipes is called the intersecting line. After the main pipe is positioned, the large sample of the intersecting line must be accurately released first, and then the other pipes are welded to the main pipe. Since the joint angle of other pipes and the main pipe is not only located on the horizontal or vertical central axis of the main pipe, but also has an angle with the horizontal or vertical central axis, the angle positioning of the two intersecting pipes is difficult, and the central axis of the pipe The setting-out is inaccurate, which affects the installation quality of the pipeline. At present, there are related positioning devices in the prior art, which are not suitable ...
