Abstract

The invention discloses a built-in steel pipe mitre elbow discharging lofting device comprising a vertical rod, a circular rod, an angle scale ruler, a pointer, an elastic painting needle, a connecting rod and a transverse rod. One side of the top of the vertical rod is provided with the transverse rod, one end of the transverse rod is movably connected to the top of the circular rod, the connecting rod is arranged in the middle of the vertical rod, one end is movably connected to the circular rod, the angle scale ruler is arranged on the vertical rod in a manner of being parallel to the connecting rod, the upper portion of the connecting rod is provided with the pointer, the upper portion of the pointer is overlapped with the angle scale ruler, and the bottom of the circular rod is provided with the elastic painting needle. According to the built-in steel pipe mitre elbow discharging lofting device, by arranging the angle scale ruler and other equipment, angle lofting is implemented, complex calculation is omitted, the lofting line is accurate and smooth, the error is small, multiple times of cutting are avoided, and work intensity is reduced for workers.

Description

technical field [0001] The invention relates to a steel pipe angle measuring device, in particular to a built-in steel pipe shrimp elbow blanking and setting device. Background technique [0002] In steel pipeline project engineering, there are many elbows and corners. The angles of these elbows are determined by the line, and are often not the angle values ​​on the atlas. When making elbows, since there is no similar data in the reference atlas, it is necessary to calculate the lofting size through complex angle function calculations, and then go through on-site lofting, scribing, and then cutting and manufacturing. Complicated, usually ordinary workers do not calculate. In addition, the stakeout value calculated by using the angle function, with the larger the diameter of the pipe, the more this set of data should be, otherwise the error will be large. Once a set of calculated values ​​is wrong, it has to be recalculated, resulting in duplication of work and low efficie...
