Description

Wide area fillet weld measurer Technical Field The invention relates to the technical field of measuring devices, in particular to a wide-area fillet weld measuring device. Background In the construction of steel structures, a large amount of welding work is required, the quality control of welding is mainly controlled by a nondestructive testing technology, and the nondestructive testing method which is most widely applied in various testing methods is Visual Testing (VT). In visual inspection of fillet weld, the fillet weld inspection generally needs to measure the size of a welding leg and the size of a welding throat, but the limitations of the HJC series welding inspection rule commonly used for measuring welding seams in the current industry are quite obvious when the fillet weld is measured, as shown in fig. 14, the welding seam size measurement can only be carried out on the fillet weld of a standard 90-degree vertical angle joint, and when the welding joint is not at the 90-degree vertical angle, the welding inspection rule loses one side measurement reference surface, so that accurate measurement cannot be completed. At present, no measuring instrument or measuring method is available in the industry, and the fillet weld measurement of the acute angle or obtuse angle joint can be completed rapidly and effectively. Disclosure of Invention The invention provides a wide-area fillet weld measurer, and aims to solve the problem of fillet weld measurement of a vertical fillet joint of non-90 degrees. The wide-area fillet weld measurer is realized by the following technical scheme that the wide-area fillet weld measurer comprises a main ruler, two auxiliary rulers, two welding leg measuring rulers and a welding throat measuring ruler, wherein the two auxiliary rulers are respectively positioned at two sides of the main ruler, the two auxiliary rulers are in sliding telescopic fit with the main ruler along concentric circular tracks of the main ruler, the two welding leg measuring rulers are respectively in radial sliding fit with the two auxiliary rulers, the welding throat measuring rulers are in radial sliding fit with the main ruler, a locking mechanism is arranged between the auxiliary rulers and the main ruler, and the locking mechanism is used for fixing the relative positions of the main ruler and the auxiliary rulers after being adjusted in place. Compared with the prior art, the scheme has the following advantages and beneficial effects: According to the scheme, the two auxiliary scales slide and stretch along the concentric circular track of the main scale, a certain measuring angle range can be formed, the angle weld measuring device can be adapted to the angle weld measuring of the common acute angle, obtuse angle and 90-degree vertical angle joint in steel structure construction, the limitation that the traditional HJC-series welding inspection scale can only measure 90-degree vertical angle joint is solved, and the industry blank of non-standard angle joint weld measuring is filled. The auxiliary ruler and the main ruler are in sliding telescopic fit, and after being adjusted to be attached to the angle of the base metal, the relative position can be quickly fixed through the locking mechanism, no additional auxiliary tool is needed, and the field detection efficiency is greatly improved. The auxiliary ruler can be contracted to the main ruler after measurement is completed, so that the whole volume is reduced, portable storage is realized, and convenience is brought to carrying and storage on a construction site. In this scheme, the leg dipperstick and the radial sliding fit of attaching chi, the radial sliding fit of throat dipperstick and main scale can independently accomplish the measurement of leg size and throat size respectively, and the reading is direct and accurate. The measuring process does not need to disassemble or adjust the device for multiple times, can acquire two key dimension data of the same fillet weld at one time, and meets the conventional measuring requirement of steel structure welding construction. Further, the main ruler and the auxiliary ruler are of fan-shaped structures, two concentrically arranged slide rail grooves are formed in the main ruler, the slide rail grooves are arc-shaped grooves, one side of each of the two auxiliary rulers is connected with a slide rail, and the two slide rails are respectively in arc-shaped sliding fit with the two slide rail grooves; The main ruler is also provided with a throat sliding groove along the radial direction of the main ruler, the throat sliding groove is positioned on the symmetrical line of the main ruler, the throat measuring ruler is in sliding fit with the throat sliding groove, the two auxiliary rulers are provided with welding leg sliding grooves along the radial direction of the auxiliary rulers, and the two welding leg measuring rulers are respectively in sliding fit with the two welding leg sliding groove
