Abstract

The invention relates to a hoisting and turning-over device and method for a large chemical container. The device comprises an arch-shaped assembly, a connection bolt and a nut, wherein the arch-shaped assembly is connected with the large chemical container by the connection bolt and the nut; the arch-shaped assembly comprises a circular-arc steel plate and a support steel plate; and the two endsof the circular-arc steel plate are respectively connected with two ends of the support steel plate by connecting steel plates. by the adoption of the hoisting and turning-over device disclosed by the invention, the large chemical container can be turned over to be vertical from horizontal or can be turned over to be horizontal from vertical. The large chemical container has a simple structure and the method is safe and reliable.

Description

technical field [0001] The invention relates to a lifting and turning device and method, in particular to a lifting and turning device and method for turning a large chemical container from horizontal to vertical, or from vertical to horizontal. Background technique [0002] In the prior art, some large chemical containers, such as the lower shell of the IGCC (Integrated Gasification Combined Cycle Power Generation System) gasifier, need to be assembled with internal parts. Due to structural reasons, after the gasifier cylinder is assembled, it needs to be hoisted into a deep pit and then further assembled with internal parts. The diameter of the lower cylinder of the IGCC gasifier is 4810mm, the wall thickness is 85mm, the total length is 19m, and the total weight is 279 tons. If the necessary measures are not taken, during the lifting process, after one end of the cylinder is lifted, a part of the other end will bear a huge weight, which may damage the lower cylinder of t...
