A bridge u-rib anti-deformation welding displacement table

Abstract

The invention provides a bridge U-shaped rib plate reverse deformation welding positioning table which comprises supports, lifting devices and a supporting rack. The lifting devices are separately arranged in the middles of the supports and connected with the middle of the supporting rack. Pin shaft locking parts are arranged at the positions, corresponding to the supports, of the two ends of the supporting rack. After one end of the supporting rack is locked to the corresponding support, the corresponding lifting device rises to support the supporting rack to enable an acute angle to be formed between the supporting rack and the horizontal direction, and after the lifting device falls, the locking end of the supporting rack is unlocked, the other end of the supporting rack is locked to the corresponding support, and when the corresponding lifting device rises again, an acute angle is formed between the supporting rack and the other end of the support, and left-right rollover is achieved. The bridge U-shaped rib plate reverse deformation welding positioning table has the most important characteristics that the operation heights of workpiece feeding and discharging are effectively decreased, modification of foundation deep-excavation is not needed for a workshop, the capital construction cost is saved, and the mounting flexibility of equipment is improved.

Description

technical field [0001] The invention belongs to the technical field of welding fixtures, and in particular relates to a displacement adjusting table used for anti-deformation welding of bridge U ribs. Background technique [0002] With the rapid development of welding technology and the improvement of automation level, the shifting table used in the welding process of bridge U ribs can no longer meet the development of welding technology. Most of the existing welding shifting tables for U-ribs on the bridge base plate are single-hinge point rotation or large-scale shifting tables are built by digging deep foundations in the workshop. This type of shifting table not only brings high labor intensity to welding technicians , while also increasing the non-effective working time occupied by the displacement, and the clamping device on the displacement table has no wide applicability for bridge substrates of different sizes. In addition, the anti-deformation effect of the shiftin...
