Embodiment Construction
[0021] The present invention is described in detail below in conjunction with accompanying drawing:
[0022] A convenient measuring mechanism for U-shaped rib welding groove angle, comprising an L-shaped inner dial plate 1, an L-shaped outer dial plate 2, a rotating shaft 3 with threads at both ends, an inner dial gauge needle 4 and an outer dial gauge needle 5, An inner annular step 6 and an outer annular step 7 are respectively arranged on the rotating shaft 3. The structure of the L-shaped inner dial plate 1 is exactly the same as that of the L-shaped outer dial plate 2. At the top corner of the L-shaped inner dial plate 1 and the top corner of the L-shaped outer dial plate 2 are provided with a rotating shaft through the installation through hole 20, and the L-shaped inner dial plate 1 is fixedly sleeved on the inner annular step 6 on the rotating shaft 3 through the installation through hole 20 through the rotating shaft. The L-shaped outer dial plate 2 is fixedly sleeved...

The invention discloses a convenient measuring mechanism and a measuring method for the angle of a U-shaped rib welding groove, which solves the problems of difficult operation and measurement error in measuring the welding groove angle of a U-shaped rib plate in the prior art. The L-shaped inner dial plate (1), the rotating shaft (3) and the L-shaped outer dial plate (2) form the dial frame of the measuring mechanism, and the inner dial scale is arranged on the outer surface of the L-shaped inner dial plate (1). 12), the inner dial pointer (4) is arranged on the outer rotating shaft (3) of the L-shaped inner dial plate, and a triangular hook-shaped ruler (8) is arranged at the tail of the inner dial pointer (4). An outer dial scale (13) is arranged on the outer surface of the dial plate (2), an outer dial pointer (5) is arranged on the outer rotating shaft (3) of the L-shaped outer dial plate, and an outer dial pointer (5) is arranged at the tail of the outer dial pointer. Right-angled trapezoid leans against chi (10). The measurement accuracy is greatly improved, and the on-site operation is simple and easy.
Description
technical field [0001] The invention relates to an angle measuring device, in particular to a convenient measuring device and a measuring method for accurately and quickly measuring the angle of a welding groove on a U-shaped floor plate of a bridge. Background technique [0002] Steel U-shaped ribs are widely used in the roof or bottom plate support of urban overpass bridge systems. U-shaped ribs are fixed on the steel roof or bottom plate by welding to strengthen the support strength of the top or bottom plate. U-shaped ribs Before welding with the top or bottom plate, it is necessary to make a welding groove on the U-shaped rib. The U-shaped rib is connected to the top or bottom plate through the welding groove. The bottom plate is fixed and welded together; the angle of the welding groove on the U-shaped rib will directly affect the difficulty of the welding operation and the quality of the welding; when designing a bridge, the welding slope of the U-shaped rib used as t...
