Self-climbing scaffold device for arch bridge rib

Abstract

The invention relates to a self-climbing scaffold device for an arch bridge rib. The self-climbing scaffold device comprises a connecting transverse plate, a hanging basket and a traction mechanism, wherein the traction mechanism is matched and connected with the connecting transverse plate; the self-climbing scaffold device for the arch bridge arch rib further comprises a sliding butt joint mechanism; the sliding butt joint mechanism comprises a main electric telescopic rod, a linkage rod, a first strip-shaped through opening, a hanging rod, a limiting clamping piece, a positioning top plate, a pulley, an auxiliary electric telescopic rod and an auxiliary side clamping mechanism. The main electric telescopic rod is connected to the connecting transverse plate. The hanging rod penetrates through the first strip-shaped through opening. The limiting clamping piece is connected to the hanging rod. One end of the linkage rod is movably connected to the suspender, and the other end of the linkage rod is movably connected to the suspender. The device has the beneficial effects that automatic butt joint with arch ribs of the arch bridge is facilitated, the stability of sliding connection is guaranteed, and the installation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of scaffolding for arch ribs of arch bridges, in particular to a self-climbing scaffolding device for arch ribs of arch bridges. Background technique [0002] An arch bridge is a round arched bridge body, and the supporting ribs formed by it are also arched. Generally, during the construction or maintenance of an arch bridge, it needs to move along the arch ribs of the arch bridge, mainly relying on the scaffolding that can be climbed. Workers stand in the hanging basket equipped with the scaffolding, but generally when installing the scaffolding equipment on the arch rib of the arch bridge, it is necessary to manually adjust and fix the position of the pulleys that are docked on the scaffolding, and the installation efficiency is low. If the support point of the pulley is offset directly above the center point of the arch rib, the smooth movement of the pulley after docking cannot be ensured. Contents of ...
