Mobile variable radius arch bridge support without disassembly

Abstract

This invention relates to a mobile, variable-radius, non-disassembly-required arch bridge support, comprising a mobile platform, a lifting platform on the mobile platform, an arched frame on the lifting platform, and multiple variable-diameter supports on the arched top surface of the arched frame, the top surfaces of the multiple variable-diameter supports collectively forming an arched support surface; the variable-diameter support includes a bottom panel, a top panel, a first connecting rod, and a first lifting mechanism; the bottom panel is fixedly connected to the arched frame, the top panel is part of the arched support surface, one end of the first connecting rod is rotatably connected to the bottom panel, and the other end is rotatably connected to the top panel; one end of the first lifting mechanism is rotatably connected to the bottom panel, and the other end is rotatably connected to the top panel; the advantages are: by setting up a mobile, variable-diameter support to replace the existing supports used in arch bridge construction, the support is non-disassembly-required and recyclable, shortening the construction time and reducing labor costs.
