Description

Box girder post-pouring cross beam construction operation platform Technical Field The utility model relates to the technical field of civil engineering, in particular to a box girder post-pouring cross beam construction operation platform. Background Along with the increasing of the domestic construction technology level, in the construction process of a small pre-stress box girder of a highway, a middle cross beam of a railway T-shaped girder and an end cross beam, a wooden template is usually adopted for opposite pulling construction, workers need to work below the box girder, in the process construction, the steel bars and the templates are usually transferred by manpower to be matched with a simple hanging basket for working, or a climbing vehicle is adopted for carrying construction devices, the process uses the manpower to transfer the steel bars and the templates, wastes time and labor, the simple hanging basket has high safety risk, the device is not easy to transport, the climbing vehicle has large volume, the requirement on the condition of a construction site is high, and the construction limit is large. Disclosure of utility model The utility model provides a box girder post-pouring cross beam construction operation platform which can overcome certain or some defects in the prior art. The box girder post-pouring cross beam construction operation platform comprises a platform main body, wherein the platform main body comprises a main frame formed by welding a plurality of steel pipes, an installation interval is arranged in the main frame, a lifting table is arranged in the installation interval, an opening for the lifting table to pass through is formed in the bottom of the main frame, and a winch for lifting the lifting table is arranged at the top of the main frame. When a constructor uses an operation platform to carry construction devices such as steel bars, the constructor pushes the main frame to roll, 4 rollers at the bottom end of the main frame roll, so that the main frame moves to a designated place, the constructor can conveniently move the operation platform, after the main frame moves to the designated place, the constructor starts a winch, the winch drops down the lifting table, after the lifting table drops down below a box girder, the constructor below the box girder pulls open a door plate, a frame cage is opened, then the constructor carries the required construction device into the frame cage, after the carrying is completed, the constructor closes the door plate, then the door plate and the frame cage are fixed through bolts, the door plate is prevented from being opened when the winch lifts the frame cage upwards, the construction device falls down to hurt people, after the frame cage is lifted up to the box girder, the constructor opens the door plate, and takes out the construction device in the box girder. Preferably, the lifting platform comprises a rectangular frame cage, and a door plate hinged with the frame cage is arranged on one side of the frame cage.
