Seamless lapping device for bridge span vertical folding type floating bridge

Abstract

The invention discloses a seamless lapping device for a bridge span vertical folding type floating bridge and belongs to the technical field of floating bridges. The seamless lapping device for the bridge span vertical folding type floating bridge comprises a bridge span and lapping plates between the bridge spans; the bridge span is an oblong plane plate; concave structures are machined at the two ends, in the length direction of the same plane, of the plate; four connecting seats with pin holes are fixed on the end surfaces of the two ends of the plate; the four connecting seats are distributed at top corners of the plate; the lapping plates between the bridge spans are rectangular plane plates; the widths of the lapping plates between the bridge spans are half of the width of the bridge span; the thicknesses of the lapping plates between the bridge spans are equal to the depths of the concave structures on the bridge span; the two ends of the bridge span are connected with the lapping plates between the bridge spans; the lapping plates between the bridge spans at the two ends are positioned in diagonal positions of the bridge span; the lapping plates between the bridge spans are movably connected to vertical end surfaces of the concave structures of the bridge span; and the lapping plates between the bridge spans realize 180-degree rotational degrees of freedom relative to the bridge span and are limited by horizontal surfaces of the concave structures and the surfaces of the lapping plates between the bridge spans. The seamless lapping device for the bridge span vertical folding type floating bridge has the advantage that the seamless lapping of seams of the folding type floating bridge in the unfolding process can be met.

Description

technical field [0001] The invention relates to the technical field of pontoon bridges, in particular to a folding pontoon bridge that can quickly open and close waterways. Background technique [0002] The pontoon bridge has the advantages of fast erection speed, great ability to overcome river obstacles, little influence by the river bottom soil, can change with the water level, and is easy to evacuate, etc. Existing methods for opening bridge doors include: belt-type gate bridge removal method, telescopic gate bridge removal method, local truss decomposition method, overlapping gate bridge removal method, etc. Above-mentioned these pontoon bridge erecting methods are complicated to operate and use, the number of personnel is large, and the operation time is long. [0003] Vertical folding pontoon bridge is a new development direction of pontoon bridge. The bridge span is prone to motion interference during the folding process. After unfolding, there will inevitably be ga...

The above-mentioned pontoon bridge erection methods are complicated to operate, have a large number of personnel, and have long working hours

[0003] Vertical folding pontoon bridge is a new development direction of pontoon bridge. The bridge span is prone to motion interference during the folding process. After unfolding, there will inevitably be gaps between the bridge span and the bridge span, which will affect the quality of the bridge body surface.
