Described hoisting method does; When said derrick body epimere collapsed into said derrick body hypomere fully and be in the rotation falling state, boom hoisting lifted by crane the derrick device balance of said contraction state through the integral lifting otic placode that is arranged at four angles, derrick brace table upper end; Wherein, said main winch can lift with the derrick brace table together, and is overweight like integral hoisting type derrick device, also can main winch be separated with the derrick brace table, separately lifting.
5. hanging method according to claim 4 is characterized in that described mounting method is:
Step 1: with said derrick body epimere collapse into said derrick body hypomere fully and be in the rotation falling state telescopic body lifting type derrick device lift on the offshore boring island, with pin derrick brace table and offshore boring island are fixed;
Step 2: operate said derrick raising cylinder, rotate up derrick body to derrick body bottom and stop near the edge of the thribble service platform on the rig floor platform;
Step 3: the flexible hydraulic wireline winch of operation derrick stops bottom elongation derrick body epimere to said derrick body epimere with after derrick body hypomere bottom flushes;
Step 4: operate the derrick raising cylinder again, rotation derrick body to derrick body bottom and offshore boring island stop in the time of leaving safe distance;
Step 5: the bottom of operating the flexible hydraulic wireline winch elongation of derrick derrick body epimere to derrick body epimere once more stops when arriving derrick brace table top;
Step 6: operate the derrick raising cylinder once more; Rotation derrick body to derrick foreleg and said derrick foreleg support and stop when being complementary; This moment, described derrick body was in stand up position, through pin derrick foreleg lower end was connected with the derrick foreleg support fixation that is fixedly set in offshore boring island; The piston rod of the said derrick raising cylinder of operation withdrawal is to cylinder body;
Step 7: operate the flexible hydraulic wireline winch of derrick once more, derrick body epimere is increased to the extreme higher position, operate said lifting then and stretch retaining mechanism, said derrick body epimere and hypomere are stretched positional lock and fastened the highest lifting.
6. according to claim 4 or 5 described hanging methods; It is characterized in that: described lift stretch retaining mechanism comprise coupling be arranged at the flashboard fixing hole of said derrick body epimere and hypomere, with the flashboard and the flashboard telescopic oil cylinder of said flashboard fixing hole coupling setting; Described console is connected with said flashboard telescopic oil cylinder, by the operation of said console control flashboard telescopic oil cylinder; Operating the flexible hydraulic wireline winch of derrick in the step of said mounting method once more with the step that derrick body epimere is increased to behind the extreme higher position is: operate said flashboard telescopic oil cylinder; Said flashboard is inserted the flashboard fixing hole that said derrick body epimere and hypomere coupling is provided with, said derrick body epimere and hypomere are stretched positional lock and fastened the highest lifting.
