The invention relates to the technical field of gas turbine overhaul, in particular to a gas turbine rotor wheel disc hoisting tool which comprises an annular support provided with an annular guide rail; the annular gear is movably connected to the annular guide rail in the circumferential direction; the plurality of gears are arranged on the tooth surface of the annular gear at intervals and are meshed with the annular gear; the multiple screw rods are arranged in a penetrating mode in the radial direction of the annular support and connected with the multiple gears in a one-to-one correspondence mode; the plurality of lifting claws are in threaded connection with the plurality of screw rods in a one-to-one correspondence manner; according to the technical scheme, one screw can be rotated by a single person, the screw drives the gear to rotate, then the annular gear is driven to rotate on the annular guide rail, other gears are driven to rotate, and other screws are driven to rotate synchronously, so that the lifting claws in all directions are screwed in or screwed out at the same time; the hoisting efficiency is greatly improved; the concentricity of the wheel disc to be hoisted and the hoisting tool during hoisting is ensured; the safety of the hoisting process is ensured.

    本发明涉及燃气轮机检修技术领域,具体涉及一种燃气轮机转子轮盘吊装工具,包括:环形支架,设有环形导轨;环形齿轮,沿周向活动连接于环形导轨上;多个齿轮,间隔设于所述环形齿轮的齿面上,且均与所述环形齿轮啮合;多个螺杆,沿环形支架的径向贯穿设置,且与多个齿轮一一对应连接;多个吊爪,与多个所述螺杆一一对应螺纹连接;本申请采用上述技术方案,单人即可转动一个螺杆,螺杆带动齿轮转动,进而带动环形齿轮在环形导轨上转动,再带动其他齿轮转动,带动其他螺杆同步转动,使得各个方向的吊爪同时旋进或旋出,大大提高吊装的效率和保证吊装时待吊装轮盘与吊装工具的同心度;保障吊装过程安全。
