Pipeline intersecting line projecting device and projecting method

Abstract

The invention discloses a pipeline intersecting line projecting device. The pipeline intersecting line projecting device comprises a pipeline clamping mechanism, an elevation regulation mechanism and a laser projecting mechanism. The pipeline clamping mechanism comprises a first clamping body and a second clamping body which are arranged in parallel. The elevation regulation mechanism comprises a main shaft, a regulation sleeve and a scale. One end of the main shaft is connected with the first clamping body, and the other end of the main shaft is connected with the second clamping body. The regulation sleeve is installed on the main shaft and can slide in the length direction of the main shaft. The laser projecting mechanism comprises a center shaft, a rotating shaft and a laser projector. The lower end of the center shaft is connected with the regulation sleeve. The upper portion of the center shaft is connected with one end of the rotating shaft in a rotating manner. The rotating shaft can rotate around the center shaft. The laser projector is installed at the other end of the rotating shaft. The invention further provides a pipeline intersecting line projecting method. The pipeline intersecting line projecting device and method have the main beneficial effects that a plurality of reference points are projected on the pipe wall of a pipeline through the laser projecting mechanism, an operator sequentially connects the reference points so that the intersecting line lofting work can be completed, the work efficiency is improved, and the lofting precision is improved.

Description

technical field [0001] The invention belongs to the technical field of pipeline construction, and in particular relates to a pipeline intersecting line projection device and a projection 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. At present, there are mainly two methods for setting out intersecting lines. One is manual setting out, which mainly relies on the experience of the staff to make large samples of intersecting lines. , will cause corresponding troubles to the follow-up process; the other is to use templates to draw intersecting lines. Although the precision of this method is relatively high, however, different templates must be prepared for pipes with different diameters. Therefore, ther...

At present, there are mainly two methods for setting out intersecting lines. One is manual setting out, which mainly relies on the experience of the staff to make large samples of intersecting lines. , will cause corresponding troubles to the follow-up process; the other is to use templates to draw intersecting lines. Although the precision of this method is relatively high, however, different templates must be prepared for pipes with different diameters. Therefore, there are Labor preparation time is long, the defect of high production cost, and the template is highly targeted, which is not conducive to reuse
