Problems solved by technology

[0002] When the steel pipes are connected, the envelope line formed by the joint between the steel pipes and the steel pipes is called the intersecting line. At present, in the pipeline construction and the production of pipeline connectors, it is generally drawn manually on one of the pipelines. Intersecting lines, or drawing by template method, this method has low accuracy of marking and easily affects the quality of products or construction
In addition, the pipes are connected with different diameters, and the pipe axes are not at the same level, the marking process of the intersecting line is more complicated

Embodiment Construction

[0029] Embodiments of the present invention are further described below in conjunction with the accompanying drawings:

[0030] Such as figure 2 As shown, an intersecting line scribing instrument includes an inline bracket 1, a tube wall fixture 2, an origin seat 3, an insertion rod 4, and an infrared projection device 5. The tube wall fixture 2 is installed on two sides of the inline bracket 1 end, the origin seat 3 is installed on the straight bracket 1, the insertion rod 4 is installed on the origin seat 3, and the infrared projection device 5 is installed on one end of the insertion rod 4.

[0031] See figure 1 , the main pipe 6 is connected to the branch pipe 7 through the reducer pipe 8 , and the envelope formed by the junction of the reducer pipe 8 and the branch pipe 7 is an intersecting line 9 . When adopting this device to carry out intersecting line 9 payout to branch pipe 7, this device needs to be installed and clamped on the main pipe 6 (such as figure 2 sho...

Abstract

The invention discloses an intersecting line lineation instrument and method. The lineation instrument comprises a linear support, pipe wall clamps, an original point base, an inserting rod and an infrared projection device. The pipe wall clamps are arranged at the two ends of the linear support. The original point base is arranged on the linear support. The inserting rod is arranged on the original point base. The infrared projection device is arranged at one end of the inserting rod. Compared with the prior art, the intersecting line lineation instrument and method have the beneficial effects that firstly, the operation that the large radius of a pipeline is changed into the small radius, the small radius of the pipeline is changed into the large radius, and intersecting lines of pipelines with different elevations are subjected to lineation can be rapidly finished; and secondly, the linear support can be rapidly installed on the pipeline through the pipe wall clamps, the moving radius of an infrared transmitter can be rapidly adjusted on the original point base, a drive mechanism on the original point base is automatically rotated, the intersecting line lofting work is rapidly finished, and the lineation precision and work efficiency are improved.

Description

technical field [0001] The invention relates to the technical field of pipeline construction, in particular to an intersecting line marking instrument and a marking method. Background technique [0002] When the steel pipes are connected, the envelope line formed by the joint between the steel pipes and the steel pipes is called the intersecting line. At present, in the pipeline construction and the production of pipeline connectors, it is generally drawn manually on one of the pipelines. Intersecting lines, or drawn by the template method, this method has low marking accuracy and is likely to affect the quality of products or construction. In addition, the pipes are connected with different diameters, and the pipe axes are not at the same elevation, the marking process of the intersecting line is more complicated. Contents of the invention [0003] The purpose of the present invention is to address the deficiencies of the prior art, to provide an intersecting line markin...
