5. hanging method according to claim 4, is characterized in that described mounting method is:
Step 1: described derrick body epimere collapsed into described derrick body hypomere completely and be lifted on offshore boring island in the telescopic body lifting type headframe device of rotation falling state, derrick brace table and offshore boring island being fixed with pin;
Step 2: operate described derrick lifting fluid cylinder, rotate up derrick body to derrick body bottom and approach the Edge-stopping of the thribble service platform on rig floor platform;
Step 3: the flexible hydraulic wireline winch of operation derrick stops extending after derrick body epimere flushes with derrick body hypomere bottom to described derrick body epimere bottom;
Step 4: operate derrick lifting fluid cylinder, rotation derrick body stops in the time that derrick body bottom and offshore boring island leave safe distance again;
Step 5: again operate the flexible hydraulic wireline winch elongation of derrick derrick body epimere and stop in the time that the bottom of derrick body epimere arrives derrick brace table top;
Step 6: again operate derrick lifting fluid cylinder, rotation derrick body to derrick foreleg and described derrick foreleg stops when supporting and matching, now described derrick body, in stand up position, is supported derrick foreleg lower end to be fixedly connected with the derrick foreleg that is fixedly installed on offshore boring island by pin; The piston rod of the described derrick lifting fluid cylinder of operation retraction is to cylinder body;
Step 7: again operate the flexible hydraulic wireline winch of derrick, derrick body epimere is increased to extreme higher position, then lift described in operation and stretch retaining mechanism, described derrick body epimere and hypomere are stretched to position and are locked the highest lifting.
6. according to the hanging method described in claim 4 or 5, it is characterized in that: described lifting stretched retaining mechanism and comprised that coupling is arranged at the flashboard fixing hole of described derrick body epimere and hypomere, mates the flashboard and the flashboard telescopic oil cylinder that arrange with described flashboard fixing hole, described console is connected with described flashboard telescopic oil cylinder, by the operation of described console control flashboard telescopic oil cylinder; In the step of described mounting method, again operating the step that the flexible hydraulic wireline winch of derrick is increased to derrick body epimere behind extreme higher position is: operate described flashboard telescopic oil cylinder, described flashboard is inserted to the flashboard fixing hole that described derrick body epimere and hypomere coupling arranges, described derrick body epimere and hypomere are stretched to position and are locked the highest lifting.
