摘要：【中文】本发明公开了一种用于管道弯头安装的测量工具，属于管道安装领域。所述测量工具包括：支撑件、角度测量件，以及同轴设置的第一激光光源、第二激光光源与第三激光光源；角度测量件垂直设置在支撑件上；第一激光光源可转动地设置在角度测量件的上表面上；第二激光光源设置在角度测量件的下表面上；第三激光光源设置在支撑件上；第一激光光源、第二激光光源均可沿角度测量件的径向发射激光，第三激光光源可沿支撑件的轴向发射激光。本发明不仅可方便地对相邻水平管段之间的待施工弯头的弯曲角度及偏转角度进行准确测量，加快测量速度，提高测量精度，也可对待施工弯头进行下料作业，扩大测量工具的使用范围，便于推广。 【EN】The invention discloses a measuring tool for installing a pipeline elbow, and belongs to the field of pipeline installation. The measuring tool comprises: the device comprises a supporting piece, an angle measuring piece, a first laser light source, a second laser light source and a third laser light source which are coaxially arranged; the angle measuring part is vertically arranged on the supporting part; the first laser light source is rotatably arranged on the upper surface of the angle measuring piece; the second laser light source is arranged on the lower surface of the angle measuring piece; the third laser light source is arranged on the support piece; the first laser light source and the second laser light source can both emit laser along the radial direction of the angle measuring piece, and the third laser light source can emit laser along the axial direction of the supporting piece. The invention can not only conveniently and accurately measure the bending angle and the deflection angle of the elbow to be constructed between the adjacent horizontal pipe sections, accelerate the measurement speed and improve the measurement precision, but also can carry out blanking operation on the elbow to be constructed, thereby enlarging the application range of the measuring tool and being convenient for popularization.
