Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary positioning for bridge parts processing, in particular to an angle-adjustable positioning device for assembling an open rib. Background Art

[0002] Most bridge parts are large in size and weight. In order to enhance the overall strength of bridge parts, various stiffening ribs (or open ribs) are often welded on the beam parts. After the stiffening ribs are welded at a certain position on the inner wall of the arc plate or steel tube, in order to facilitate the subsequent welding of the stiffening ribs, it is usually necessary to rotate the arc plate or steel tube so that the position to be welded is at the bottom, and the welded stiffening ribs are at a high position. Since the stiffening ribs are long and heavy, in order to avoid the stiffening ribs from overturning or the initial welding posture angle from shifting, temporary support, packaging and other auxiliary components are often required to temporarily position the stiffening ribs. These temporary auxiliary components often need to be welded on the stiffening ribs and arc parts (arc plates or steel tubes). In the subsequent processing process, these temporary auxiliary components often need to be disassembled. Since the auxiliary components are welded on the arc parts, the subsequent disassembly operation is relatively labor-intensive and time-consuming, and the disassembled auxiliary components are difficult to reuse, which will consume more auxiliary materials.

[0003] Therefore, the present application proposes a positioning device that can be recycled and reused to avoid waste of auxiliary materials, and can be quickly assembled and disassembled, and can clamp and position open ribs with different installation angles. Utility Model Content
