Gangway structure for connecting floating bridge with floating platform

Abstract

The invention provides a gangway structure for connecting a floating bridge with a floating platform and belongs to the technical field of floating bridge connection. The gangway structure for connecting the floating bridge with the floating platform comprises the floating bridge, the floating platform, footplates, a gangway and supporting limiting frames, wherein the footplates are arranged on the floating bridge and the floating platform; the gangway is hinged between the footplates of the floating platform and the floating bridge; and the supporting limiting frames are hinged on the floating bridge and the floating platform. According to the gangway structure for connecting the floating bridge with the floating platform, as a platform footplate is hinged on a floating bridge platform and the platform footplate is matched with a truss type gangway, the adapted draft difference is great and the adaptation is high; as the supporting limiting frames are arranged and a main support is arranged in the form of a double A-shaped truss, the position of the gangway structure between the floating platform and the floating bridge is effectively limited at a maximum draft difference and at a minimum draft difference so as to ensure that vehicles can safely pass; damage of the bridge body caused by collision between the floating bridge and the floating platform can be avoided; and moreover, the design load of the truss type gangway is reduced, the weight of the structure is reduced and the safety is enhanced.

Description

technical field

[0001] The invention relates to the technical field of floating bridge connection, in particular to a springboard structure connecting a floating bridge and a floating platform. Background technique

[0002] As one of the main tools for crossing ravines, bridges have a long history of construction, play a pivotal role in people's production and life, and become a necessary carrier tool in life.

[0003] At present, the existing bridges include reinforced concrete bridges and steel structure floating bridges. Reinforced concrete bridges are durable and have low maintenance costs. The construction period is short, and it can be recycled and used with stronger adaptability. It is generally arranged in places with large environmental changes and instability, such as the sea. In the sea with strong wind and waves, due to the deep water depth and long distance, the cost of building a reinforced concrete bridge is not only high, but also there is a risk of damage, ...
