Description

Technical Field

[0001] The utility model relates to the technical field of pressure vessel manufacturing, in particular to a tool for measuring the angle of pressure vessel equipment. Background Art

[0002] During the manufacturing inspection process of Class A and B welded joints of pressure vessel cylinders, the circumferential and axial edge angles of welded joints and weld excess height are indicators that must be controlled, and are generally inspected and measured with a welding inspection ruler. When the weld excess height cannot be inspected with a welding inspection ruler due to factors such as size or structure, a sample must be made for inspection and measurement. The sample for edge angle inspection and measurement is specified in 6.5.2 of GB / T150.4-2011 as follows: The edge angle formed in the circumferential direction of the welded joint is inspected with an inner sample or outer sample and a ruler with a chord length equal to Di / 6 and not less than 300mm. The disadvantages of this detection method are: (1) The equipment size and structural factors have a serious impact on the edge angle detection. The inspection position must be selected according to the equipment size and structure. When the edge is concave toward the shell, an external sample is used and the detection is performed outside the cylinder; when the edge is convex toward the shell, an internal sample is used. At this time, the measurement personnel must drill into the cylinder for detection; (2) When the product structure size is inconsistent, it is necessary to make samples of corresponding specifications. The number is large and it is difficult to meet the needs of multiple varieties of products; (3) When the sample is tested, it is also necessary to use other tools (angle measuring instruments, mobile light sources, brackets, etc.). The cumulative error during the measurement process is large and the accuracy is low; (4) The measurement process is limited by the direction of the edge angle. It is particularly difficult to measure the edge angle of the welded joint with misaligned edges. Utility Model Content

During the measurement process, the vertical ruler 2 is perpendicular to the main ruler 1, and scale lines are provided on the surfaces of the main ruler 1 and the vertical ruler 2. The distance between the contact position of the two ends of the main ruler 1 with the inner wall of the cylinder and the lower surface of the main ruler 1 is the same as the distance between the contact position of the vertical ruler 2 with the inner wall of the cylinder from the zero scale. The reading size of the main ruler 1 and the vertical ruler 2 is the actual measured size. The vertical ruler 2 is locked by the vertical locking device for easy reading.

[0019] The utility model realizes the measurement of the edge angle of the pressure vessel by sliding the transverse retainer on the outside of the main scale 1 and the vertical scale 2 in the vertical retainer 7, and adjusting the positions of the transverse retainer and the vertical scale 2 as needed.
