An offshore liftable pontoon equipped with auxiliary docking and anti-rolling devices

Abstract

The invention discloses a liftable pontoon bridge at sea equipped with an auxiliary docking and anti-rolling device. The device comprises a lifting bridge body, a main body of the pontoon bridge, an anti-rolling damping net, a clamping mechanism at the head end and a clamping mechanism on the port side. There is a buoyancy chamber inside the main body of the pontoon, which can change the draft of the pontoon in cooperation with the lifting bridge body, so as to reduce the water surface area of ​​the pontoon and reduce the swaying movement; The end clamping mechanism cooperates to realize the connection between the pontoons; the starboard side of the pontoon main body is equipped with a starboard connecting body, which cooperates with the port side clamping mechanism of another pontoon to realize the side connection between the pontoons; the anti-rolling damping net is used to increase Damping during the movement of the pontoon to reduce the swaying motion of the pontoon in waves. The invention solves the problem of difficult docking construction of the floating bridge under relatively high sea conditions, and at the same time reduces the swaying motion response of the floating bridge in severe sea conditions, reduces the structural stress amplitude of the connection of the floating bridge, and prolongs the service life.

Description

technical field [0001] The invention belongs to the technical field of design and manufacture of ships and marine engineering equipment, and in particular relates to a liftable floating bridge on the sea equipped with auxiliary docking and anti-rolling devices. Background technique [0002] The pontoon bridge has the advantages of flexible construction and adjustable overload area of ​​the bridge deck. It is one of the commonly used equipment for material and equipment transportation across the river and unloading operations on coastal beaches. At present, the main working scenarios considered in the design of most pontoon bridges are inland rivers and coastal beaches with good sea conditions. At this time, the external wind, wave, current and other environmental loads are small compared to the inertia characteristics and recovery stiffness coefficient of the pontoon itself, and the induced pontoon movement is very small, so the connection and construction work is easy and t...
