Movable hanger operating platform and manufacturing, installing, using and removing methods thereof

Abstract

The invention discloses a movable hanger operating platform which structurally comprises a truss lower, two pairs of longitudinally symmetrical connecting rod parts are welded on the truss base plate in a transversely symmetrical mode, a monorail trolley is arranged at the upper end of each connecting rod part and forms a kinematic pair with the a repair rail at the bottom of the lower bridge face of a steel trussed beam, the length*width specification of the truss base plate is 16.5m*8m, riffled steel plates are laid on the top face of the truss base plate, and guardrails are arranged on the periphery of the top face of the truss base plate. The invention further discloses manufacturing, installing, using and removing methods of the movable hanger operating platform. The movable hanger operating platform has the advantages of being low in cost, easy to manufacture, convenient to operate and capable of being recycled, and not only overcoming a number of defects of the prior art and solving the problem that construction is inconvenient in an assembling process of the steel trussed beam, but also ensuring that no potential safety hazards of objects falling from high altitude exist and the ambient environment is not polluted, so that the technical purposes of being safe and reliable, reducing cost, shortening construction periods and improving efficiency are achieved.

Description

technical field [0001] The invention relates to an operation platform, more specifically, the invention relates to a movable hanger operation platform for assembling steel truss girders and methods for making, installing, using and dismantling the same. Background technique [0002] The inventor of the present application once participated in the construction of the main bridge of Fenfangwan Yangtze River Bridge in Jiangjin District, Chongqing City. Light rail bridge, the steel truss girder with a total length of 897m is divided into 61 segments. The steel truss girder constituting the bridge has an inverted trapezoidal cross-section, the upper and lower bottom widths of the inverted trapezoid are 37m and 16.5m respectively, the height is 12.5m, and the length of each standard segment is 16m. In the splicing construction of steel truss girders, high-strength bolts are used to connect and weld each section, while the construction of the bottom of the lower deck includes not ...
