Embodiment
[0081] Crane and tooling:
[0082] Two cranes are arranged in the turbine room, one 225T trolley and one 130T trolley are arranged on the trolley. The special tooling includes a well-shaped frame and two sets of pole beams.
[0083] Lug arrangement:
[0084] Each vertical high-pressure heater manufacturer sets 4 temporary lifting lugs 11 and 2 temporary supports 12 on the vertical high-pressure heater. (Temporary lug 11 is used for the rotation of vertical high-pressure heater 1; Temporary support 12 is used for the support and connection of well-shaped frame 2 and vertical high-pressure heater 1.)
[0085] Vertical high pressure heater rotates up:
[0086] Use a 225T hook with the lifting beam to lift the temporary lifting lug 11 on the upper part of the vertical high-pressure heater, use a 130T hook with the lifting beam to lift the temporary lifting lug 11 at the lower part of the vertical high-pressure heater, and lift the four hooks at the same time. After the vertical...

The invention discloses a method for placing a vertical high-pressure heater of a power plant in position through #-shaped frames, and mainly relates to the field of mounting of large power plant equipment. The method comprises the following steps: S1, temporary lifting lugs and temporary supports are prefabricated on the vertical high-pressure heater; S2, a hoisting channel is reserved in an operation layer platform of a construction site; S3, the vertical high-pressure heater in a horizontal state is transported to the lower side of the hoisting channel through a transport cart; S4, the vertical high-pressure heater is hoisted away from the transport cart through two travelling cranes, and then the transport cart is driven away from the construction site; S5, the vertical high-pressure heater is rotated from the horizontal state to a vertical state through cooperation of the two travelling cranes; and S6, the vertical high-pressure heater in the vertical state is vertically hoisted through one of travelling cranes, and the #-shaped frames are additionally mounted at the temporary supports of the vertical high-pressure heater. Through the method, the problem that under the condition of narrow height space, the high-pressure heater cannot cross the operation layer platform to be placed in position through an original technical method can be solved.
Description
technical field [0001] The invention relates to the field of large-scale power station equipment installation, in particular to a method for placing a vertical high-pressure heater in a power plant using a well-shaped frame. Background technique [0002] The vertical high-pressure heater is an important facility of the power station. Generally, after the manufacturer completes the manufacture of the vertical high-pressure heater, it is transported to the construction site for installation. Due to the heavy weight and high height of the vertical high-pressure heater, the vertical high-pressure Problems with the installation of heaters have been plaguing the staff. [0003] The existing technical solution is to enable the vertical high-pressure heater to be hoisted from the lifting hole and realize rotation upright and translational positioning under the premise that the driving girder of the steam turbine workshop is reinforced to the load-bearing capacity to meet the hoistin...
