TECHNICAL FIELD

[0002] The 9H grade gas turbine waste heat boiler is a core equipment of a high-efficiency combined cycle power generation system, and the pressure part module of the waste heat boiler is a box-shaped integral structure composed of a serpentine tube row. After the box-shaped integral pressure part module is horizontally transported to the installation site by a flat car, it needs to be turned from a horizontal posture to an upright posture by hoisting equipment and then hoisted and installed into the flue of the gas turbine waste heat boiler. In the on-site hoisting construction, the traditional hoisting and turning-over process of the pressure part module is carried out by a fixed gantry crane plus a temporarily welded turning-over support. This hoisting tool and hoisting method have the following problems: (1) there is a safety hazard. The inertial moment of the heavy pressure part module is large when it is turned over. The temporarily welded turning-over support has a high risk of breaking under the action of large inertial moment, which can easily cause an overturning accident; (2) the temporarily welded turning-over support has poor compatibility. The sizes of the pressure modules of the H grade gas turbine waste heat boiler are different, and the specifications designed by different manufacturers are different. The turning-over support tool is difficult to adapt to pressure modules of different sizes, and various sizes of temporary turning-over supports need to be customized, resulting in an increase in construction cost; (3) the temporarily welded turning-over support directly contacts the pressure module, which can damage the surface of the base material of the pressure module, especially for nickel-based alloy materials, and can also cause intergranular corrosion hazards; (4) the hoisting rope is easy to entangle during turning over, which forms a hoisting hazard.

Control the circular tube beam (23) horizontally upward, make the bottom support frame (4), the compression part module (1), the front side channel steel beam (10) of the turning frame, the rear side channel steel beam (11) of the turning frame and the top end lifting beam (12) of the tool rise, leave the transport flat car (9); The sixth step, control the main hook (19) and the auxiliary hook (20) at the same time, make the bottom support frame (4) and the compression part module (1), and the "door” shape frame, clockwise tilt and overturn, until the bottom support frame (4), the compression part module (1) and the "door” shape frame are in vertical state, make the main hook (19) and the auxiliary hook (20) stop in the air.
2. The auxiliary turning and lifting method of the waste heat boiler compression part module according to claim 1, wherein: The seventh step, lift the main hook (19) upward, make the first main lifting rope (21) and the second main lifting rope (22) bear the whole weight of the bottom support frame (4), the compression part module (1) and the "door” shape frame, make the third auxiliary lifting rope (30) and the fourth auxiliary lifting rope (31) not bear weight; The eighth step, remove the lower end of the third auxiliary lifting rope (30) from the third lifting lug (15) and connect it to the fifth lifting lug (17); remove the fourth auxiliary lifting rope (31) from the fourth lifting lug (16) and connect it to the sixth lifting lug (18); lift the auxiliary hook (20) upward, so that the third auxiliary lifting rope (30) and the fourth auxiliary lifting rope (31) are in the state of bearing the weight of the front side channel steel beam (10) of the turning frame and the rear side channel steel beam (11) of the turning frame; The eighth step, remove the connecting bolts of the tool top end lifting beam (12) and the front side channel steel beam (10) of the turning frame, and remove the connecting bolts of the tool top end lifting beam (12) and the rear side channel steel beam (11) of the turning frame; then remove the connecting bolts of the front side channel steel beam (10) of the turning frame and the rear side channel steel beam (11) of the turning frame and the annular fixed frame connecting beam (3) on the side of the compression part module (1); separate the front side channel steel beam (10) of the turning frame and the rear side channel steel beam (11) of the turning frame from the tool top end lifting beam (12), so as to form a separated lifting state, in which the first main lifting rope (21) and the second main lifting rope (22) vertically lift the compression part module (1) and the bottom support frame (4) through the tool top end lifting beam (12); the third auxiliary lifting rope (30) vertically lifts the front side channel steel beam (10) of the turning frame, and the fourth auxiliary lifting rope (31) vertically lifts the rear side channel steel beam (11) of the turning frame.
3. The auxiliary turning and lifting method of the waste heat boiler compression part module according to claim 2, wherein: The ninth step, the main lifting crane (7) controls the main hook (19), after lifting and installing the compression part module (1) and the bottom support frame (4) into the flue of the boiler, remove the connecting bolts between the tool top end lifting beam (12) and the side top end lifting beam (5), and the middle top end lifting beam (6), and put the tool top end lifting beam (12) on the ground; the auxiliary hook (20) puts the front side channel steel beam (10) of the turning frame and the rear side channel steel beam (11) of the turning frame on the ground through the triangular lifting frame composed of the four auxiliary lifting ropes. The tenth step is to assemble the top end of the hoisting beam (12), the front side of the beam (10) and the rear side of the beam (11) to another piece of the pressure part module (1), repeat the fourth step to the ninth step, and complete the hoisting and installation work of another piece of the pressure part module (1).
