Description

TECHNICAL FIELD

[0001] The utility model relates to module hoisting field, concretely is a turning-over device for waste heat boiler module. BACKGROUND

[0002] During the installation of the waste heat boiler of the second phase project of Bahrain Adu, two pieces of harp were damaged during transportation and needed to be replaced by purchasing from the boiler factory. According to the conventional installation process, the installation of harp must be carried out from the front of the furnace to the back of the furnace in sequence. If the installation of all modules is waited until the new harp arrives, the construction period of the entire waste heat boiler installation will be greatly delayed, which will have a great impact on the progress of the project.

[0003] During this process, the in-place guide rail and the electric lifting device are first installed on the boiler top beam to prepare for module movement and height adjustment. Then the turning-over frame is fixed on the boiler stand column to facilitate the turning-over of the module under the cooperation of the crane. After the module is unloaded from the vehicle, it is slowly lifted, fixed and turned over to the correct installation direction through the lifting frame and the hoisting beam. Subsequently, the module after turning over is slowly moved into the boiler interior along the guide rail through the electric lifting adjustment device and is fixed at the predetermined position by using the lifting rod. Finally, the turning-over frame is sent back to the starting point to prepare for the repeated operation on the next piece of module. The entire process ensures that even if a module is damaged, the construction can continue through reverse hoisting, thereby minimizing the impact on the overall construction period.

[0004] In order to continue the installation of other modules without being affected by the damaged module under the condition of piece-by-piece supply of waste heat boiler modules and module damage, without causing large-scale impact on the construction period, the reverse installation and the normal installation are adopted to preferentially complete the alignment of the normally installed modules and the subsequent pipeline installation work, so that part of the pipeline installation work can be smoothly carried out, thereby achieving the purpose of shortening the construction period. The damaged harp is installed in reverse, and the remaining parts are installed in normal mode, thereby avoiding the situation that all harps cannot be installed. During this process, there is a lack of a supporting fixed frame for turning-over, which affects the efficiency of turning-over. UTILITY MODEL CONTENTS
