Multi-segment bendable plug-in modular platform for u-rib interior construction

Abstract

The invention relates to the technical field of bridge maintenance, and discloses a multi-segment bendable plug-in modular platform for internal construction of U-ribs, which includes at least two platform segments and a plug-in mechanism, and adjacent platform segments pass through The oppositely arranged plug-in mechanism is connected; each platform segment includes a platform body and a running mechanism installed under the platform body; each plug-in mechanism includes a flexible shell connected to the platform body and a mechanical chuck arranged in the flexible shell , Each mechanical chuck is provided with buckles that can be fastened with each other. The multi-segment bendable plug-in modular platform for U-rib internal construction of the present invention is divided into at least two platform segments and connected by a plug-in mechanism, which effectively reduces the rigid length of the construction platform and does not need to make a long U-rib The entrance of the U rib can be placed inside the U rib, thereby avoiding the impact of the excessive length of the entrance on the bridge structure, and making the insertion operation easier; the mobile platform is divided into at least two platform segments, which also makes it easier to , can be divided into sections to pass through the curved section, making it easier to pass and also suitable for U-ribs with larger angles in the curved section.

Description

technical field [0001] The invention relates to the technical field of bridge maintenance, in particular to a multi-segment bendable plug-in modular platform for internal construction of U-ribs. Background technique [0002] Steel structure bridges have a history of more than 200 years, and their development is closely related to material technology, manufacturing technology, and structural design. In terms of structural design, steel trusses or steel plate girders were used in the early stage. Since the middle of the 20th century, with the maturity of the design level of orthotropic thin steel box girder structure and the improvement of welding technology, the steel box girder structure is characterized by its low height, light weight, high rigidity, large ultimate bearing capacity, easy manufacturing and structural Continuous and good features have become the main structural form of steel bridge decks. [0003] Orthotropic bridge decks are mainly composed of steel struct...

Problems solved by technology

During the welding process of the real bridge, the length of the mobile platform that can meet the U-rib supine welding is more than 1 meter. In order to put the U-rib supine welding device into the U-rib of the real bridge, a longer entrance must be made for the U-rib. However, if the entrance is too long, it will have a greater impact on the bridge structure

Furthermore, when the U-rib is a curved section, the 1-meter-long mobile platform cannot turn and walk in the curved section, so that the U-rib of the curved section cannot be welded
