Abstract

The invention relates to the technical field of bridge maintenance, and discloses a multi-section bendable plug-in type modular platform for U rib internal construction. The platform comprises at least two platform sections and plug-in mechanisms. The adjacent platform sections are connected through the plug-in mechanisms which are oppositely arranged; each platform segment comprises a platform body and a walking mechanism installed below the platform body; and each plug-in mechanism comprises a flexible shell connected with the platform body and a mechanical chuck arranged in the flexible shell, and each mechanical chuck is provided with buckles which can be buckled with each other. The multi-section bendable plug-in type modular platform for U rib internal construction is divided into atleast two platform sections which are connected through the plug-in mechanisms so that a rigid length of the construction platform is effectively reduced, the platform can be placed into a U rib without forming a long inlet, an influence of the overlong inlet on a bridge structure is avoided, and placement operation is easier; and the mobile platform is divided into at least two platform sectionsso that when a bent section is arranged in the U rib, the sections can pass through the bent section, passing is more easy and the platform can be suitable for the U rib with a large angle of the bent 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...

Embodiment Construction

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] see figure 1 , is a structural schematic diagram of a U-rib internal supine construction system using a multi-segment bendable plug-in modular platform for U-rib internal construction in a preferred embodiment of the present invention. The supine construction system inside the U-rib is used for upward grinding and welding of the area to be welded between the U-rib and the panel from the inside of the U-rib, including a construction mechanism 10 and a mobile platform 20, and the construction mechanism 10 is set on the mobile platform 20 , the mobile platform 20 moves inside the U-rib, thereby driving the construction mechanism 10 to perform welding.

[0027] The construction mechanism 10 includes a construction robot arm 11 and a construction robot arm 12 rotatably installed at the end of the construction robot arm 11 .
