Method for integrally shifting cantilever beam out of platform and moving cantilever beam back to platform
The invention provides a method for integrally shifting a cantilever beam out of a platform and moving the cantilever beam back to the platform. The method comprises a shift-out process of integrally moving the cantilever beam from a platform of a cantilever beam type drilling platform to a floating dock and a move-back process of moving the cantilever beam back to the platform from the floating dock after respectively reconstructing the cantilever beam and the platform, wherein in the shift-out process, a rigid tooling rail which is aligned to the side wall of a cantilever beam support is designed, a trolley provided with a lifting device is arranged on the tooling rail, a hydraulic system is utilized to assist a jacking top plate to jack up the cantilever beam, the lifting device is controlled to tightly jack up the top plate, the trolley and the cantilever beam are fixed by use of a horse plate, and after the trolley and the cantilever beam are relatively positioned, a hauling tooling and a winch are utilized to pull the cantilever beam to roll and slide along the tooling rail; In a move-back process, the cantilever beam is conveyed in a reverse direction and is aligned to the rail, and the cantilever beam is loaded back by use of a pushing device of the rail. The method provided by the invention has the advantages of reasonable, safe and efficient process, high tooling machinability, good construction operability and low cost.
