Problems solved by technology
The clamping of the plate unit on the welding tire frame adopts the method of screw compression or steel wire rope tightening. This single-point compression method causes wave deformation on the edge of the plate unit, and the straightness of the plate edge is not conducive to the butt joint of the plate unit. Welding
[0003] The range of anti-deformation welding in the prior art is relatively narrow. For plate elements with different plate thicknesses or different types of plate rib stiffening, multiple anti-camber values are often required, and it is necessary to manufacture multiple sets of tire frames with different anti-camber values, and the labor of the correction process is added. High strength and low efficiency, the welding deformation control of the plate unit greatly affects the workload and welding quality of the next process

The invention discloses a hydraulically adjustable antiarch value plate unit ship form welding device which is characterized by being composed of a plurality of welding jigs arranged on a welding platform. Each welding jig is composed of a guide block, a movable mold plate, a hydraulic jack, a chuck and a spiral locker. The chuck limits the edge position of a bridge deck slab, the guide block limits the moving direction of the movable mold plate, the hydraulic jack jacks up the middle of the bridge deck slab synchronously to achieve a set deformation value, and the spiral locker clamps the movable mold plate to limit the position of a welding platform ship for ship form welding. Compared with the prior art, the hydraulically adjustable antiarch value plate unit ship form welding device issimple in structure, quick to load and unload and precise in welding control. By adjusting the position of the clamp and replacing a movable arc-shaped mold plate structure, the reversible deformationwelding demands of plate units with different thicknesses and widths are met, and reversible deformation of bridge deck slabs of various specifications is achieved quickly, so that the welding quality of the plate units is improved effectively, thereby providing favorable conditions to batch production.
Description
technical field [0001] The invention relates to the technical field of welding tire frame production, in particular to a ship-shaped welding device for a hydraulically adjustable anti-arch value plate unit used for bridge steel box girders. Background technique [0002] In bridge steel box girder manufacturing engineering, the welding deformation control of steel box girder U ribs, spherical flat steel ribs and plate ribs is an important point in the quality control of plate elements. Angular deformation often occurs without anti-deformation control. The horizontal flatness, vertical flatness, and board edge straightness are seriously out of tolerance, and the correction workload is relatively large. Due to the large number of plate unit specifications and large production volume, how to improve production efficiency, complete the plate unit and beam segment manufacturing tasks within the specified construction period, design a welding device suitable for different widths, t...
