Problems solved by technology

[0004] However, for the steel structure bridges that have been built, since the U ribs are located under the roof, before the development of the U rib internal welding technology, the connection between the U ribs and the face plate was welded on one side on the outside, resulting in the construction of bridges that have been opened to traffic after a period of operation. A large number of cases of cracking at the joints between panels and U-ribs

Embodiment Construction

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] Aiming at the existing bridges, solve the narrow confined space, invisible, and long-distance weld posture adjustment problems encountered in U-rib internal supine welding at the site of the completed bridge, and provide a welding torch posture for U-rib internal supine welding system The adjustment device provides reliable and stable adjustment of the welding torch posture in a narrow space, so that the welding quality higher than the design requirements can be achieved in the internal welding seam supplementation process.

[0025] see figure 1 and figure 2 , a structural schematic diagram of a welding system using a welding torch attitude adjustment device for a U-rib internal supine welding system according to a preferred embodiment of the present invention. The supine welding system inside the U-rib is used to repair the...

Abstract

The invention relates to the technical field of bridge maintenance, and discloses a welding gun posture adjusting device for a U-shaped rib internal overhead position welding system. The adjusting device is used for adjusting the position of a welding gun for repair welding of a welding seam between a U-shaped rib and a panel from the inside of the U-shaped rib. The welding gun posture adjusting device is arranged on a walking mechanism moving in the length direction of the U-shaped rib and comprises a welding gun pitching angle adjusting mechanism, a welding gun height adjusting mechanism anda welding gun transverse moving adjusting mechanism. The welding gun is installed on the welding gun pitching angle adjusting mechanism, the welding gun pitching angle adjusting mechanism is fixed tothe welding gun height adjusting mechanism, and the welding gun height adjusting mechanism is fixed to the welding gun transverse moving adjusting mechanism. According to the invention, independent driving is adopted for achieving adjustment of the angle, the height and the transverse movement of the welding gun, the welding gun posture adjusting device can be installed at the tail ends of various automatic welding devices, and multi-dimensional accurate adjustment of the welding gun is achieved.

Description

technical field [0001] The invention relates to the technical field of bridge maintenance, in particular to a welding torch attitude adjustment device for a U-rib internal supine welding system. Background technique [0002] Steel structure bridges have a history of more than 200 years, and their development is closely related to material technology, manufacturing technology, and structural design. In terms of structural design, steel trusses or steel plate girders were used in the early stage. Since the middle of the 20th century, with the maturity of the design level of orthotropic thin steel box girder structure and the improvement of welding technology, the steel box girder structure is characterized by its low height, light weight, high rigidity, large ultimate bearing capacity, easy manufacturing and structural Continuous and good features have become the main structural form of steel bridge decks. [0003] Orthotropic bridge decks are mainly composed of steel struct...
