Multifunctional operating platform for large-volume prestressed concrete box girder tensioning

The invention discloses a multifunctional operating platform for large-volume prestressed concrete box girder tensioning, which mainly consists of a main body structure, a hoisting system, a tensioning oil pump, a tensioning jack, a tool storage box, a safety protection system, a climbing ladder and an appurtenant structure. The main body structure is a framework structure which consists of five plane trusses and two vertical trusses, and the hoisting system consists of an electric hoist, a crane girder, a walking trolley and a track. The multifunctional operating platform mainly adopts the electric hoist for lifting the jack, and electrical equipment of the electric hoist can be precisely controlled, thereby being conductive to the mounting para-position operation of the tensioning jack and ensuring the safety of the construction. The multifunctional operating platform has the advantages of strong adaptation capability, simple construction, convenient operation and high operation efficiency while tensioning
