Mechanical U rib internal welding tracking device

Abstract

The invention relates to a mechanical U rib internal welding tracking device. The device comprises a transverse sliding body, a longitudinal walking trolley, springs and a push-pull dragging plate. The transverse sliding body comprises a bevel rolling wheel, a tracking sliding plate, a welding gun support, guide rail sliding blocks and spring connecting plates. The welding gun support is obliquelyarranged on a tracking sliding plate, the spring connecting plates are arranged at upper ends of two side edges of the tracking sliding plate, the springs are arranged on the spring connecting plates, and the guide rail sliding blocks are symmetrically installed at bottoms of the two side edges of the tracking sliding plate. The longitudinal walking trolley comprises a connecting plate, an adjustable side plate, a central rolling wheel, a spring hanger, a baffle plate, a linear guide rail, a baffle plate cushion block and a rolling wheel. By using the device of the invention, uniformity and consistency of a fusion angle and a fusion depth of gas protection welding interior angle welding are stably achieved, submerged-arc welding full penetration welding quality of a non-prefabricated groove in an outer side is guaranteed, and ultrasonic inspection of welding seams of welding tests of multiple U ribs is 100% qualified.

Description

technical field [0001] The invention relates to the technical field of tracking devices, in particular to a mechanical U-rib internal welding tracking device. Background technique [0002] With the rapid development of bridge construction in our country, all-steel structure bridges have occupied a dominant position. All kinds of new bridge steel components are also constantly appearing, and the requirements for efficient automatic production and technological level are also constantly improving. Steel bridge decks are one of them. Started to use T-shaped reinforced ribs, and later developed the use of U-shaped outer corner welded ribs, and further required double-sided welding of U-shaped ribs for inner and outer corners. Now the process requirements have been further improved, and U-shaped ribs with fully automatic double-sided full-penetration welding are required. board structure. [0003] For the welding of the inner corners of the U-shaped ribs of the steel bridge de...

Problems solved by technology

The tracking deviation of the inner weld seam will affect the depth and angle of the effective fusion of the weld seam into the base metal, and then affect the remelting of the outer weld to the inner weld bead. The position where the remelting is not completely good is the incomplete penetration welding defect, which needs to be removed Weld bead repair welding
