Embodiment Construction

[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0030] Such as figure 1 Shown is the implementation flowchart of the method of the present invention. Automatic assembly method of the present invention comprises the following steps:

[0031] (1) U-shaped rib groove processing, pressing, bridge deck blanking:

[0032] After flattening the U-shaped rib with a steel plate, expand the width and length according to the design dimensions of the U-shaped rib and reserve a certain amount of processing for blanking, milling on both sides of the steel plate and processing the groove of the fillet weld (to ensure that the fillet weld of the U-shaped rib The groove angle is 50°), and then the steel plate is pressed on the molding machine to form a U-shaped rib 15; the bridge deck 14 is flattened and then unloaded.

[0033] Such as figure 2 Shown is the groove form of the U-shaped rib fille...

Abstract

The invention discloses an automatic assembly method for orthotropic plate unit U-shaped ribs. The method comprises: S1, molding U-shaped ribs; S2, blanking a bridge deck slab and forming a U-shaped rib assembly locating line; S3, locating the U-shaped ribs on an area to be welded on the bridge deck slab through a U-shaped rib assembly locating device; S4, clamping the U-shaped ribs through the U-shaped rib assembly locating device; S5, using a welding robot for U-shaped rib fillet welding positioned welding; and S6, repeating the steps till U-shaped ribs on the whole plate unit are assembled and subjected to positioned welding. The method has the advantages of being high in assembly accuracy and assembly production efficiency, stable in welding quality and the like of orthotropic plate unit U-shaped ribs and is high in applicability, capable of being popularized and applied in manufacture fields of steel structures such as ship steel structures, mechanical steel structures and building steel structures and wide in the application range.

Description

technical field [0001] The invention relates to an automatic assembly technology for U-shaped ribs of orthotropic plate units, in particular to an automatic assembly method for U-shaped ribs of bridge deck units in the manufacture of steel bridges. Background technique [0002] At present, orthotropic slab structures are widely used in the deck design of long-span steel bridges. The bridge orthotropic plate structure is a structure in which a certain number of longitudinal and transverse stiffeners are welded on the deck, bottom plate or web to increase the rigidity of the bridge deck, bottom plate or web. Since its stiffness is different in two directions perpendicular to each other, it causes structural anisotropy. [0003] The longitudinal stiffeners on orthotropic slabs generally adopt U-shaped ribs or slab ribs. For the assembly of U-shaped ribs, manual and semi-mechanized methods are generally used at present. The area to be welded is manually polished. After the U-s...
